Formate-drivengrowth coupledwith H2 production

Yun Jae Kim Marine Biotechnology Research Center

bio1213hotmailcom

Although a common reaction in anaerobic

environments the conversion of formate to

bicarbonate and H2 (HCOO- + H2O HCO3- + H2 Go = +13

kJmol) has not been considered energetic enough to support

growth of microorganisms Recently experimental evidence

for growth on formate was reported for syntrophic

communities of Moorella sp strain AMP and a hydrogen-

consuming Methanothermobacter species and of

Desulfovibrio sp strain G11 and Methanobrevibacter

arboriphilus AZ1 The basis of the sustainable growth of the

formate-utilizers is explained by H2 consumption by the

methanogens which lowers the H2 partial pressure thus

making the pathway exergonic2 However it has never been

shown before that a single strain can grow on formate by

catalyzing its conversion to bicarbonate and H2 Here we

report that several hyperthermophilic archaea belonging to

the Thermococcus genus are capable of formate-oxidizing

H2-producing growth The actual G values for the formate

metabolism were calculated to range between -8 and -20

kJmol under the physiological conditions where

Thermococcus onnurineus NA1 were grown Furthermore

we detected ATP synthesis in the presence of formate as a

sole energy source Gene expression profiling and disruption

identified the gene cluster encoding formate hydrogen lyase

cationproton antiporter and formate transporter which were

responsible for growth of T onnurineus NA1 on formate This

work represents the first demonstration of formate-driven

growth by a single microorganism with protons as the

electron acceptor and demonstrates the biochemical basis of

this ability

Formate-dependent H2 production is dependent upon

formate hydrogen lyase systems composed of the

formate dehydrogenase and membrane-associated

hydrogenase3 In Escherichia coli and Thermococcus

litoralis formate is oxidized to CO2 by formate

dehydrogenase (HCOO- rarr CO2 + H+ + 2e-) and protons are

reduced to H2 by hydrogenase (2H+ + 2e- rarr H2) in response to

the accumulation of formate during fermentation to

maintain cytoplasmic pH4-7 The formate hydrogen lyase

systems in Methanococcus maripaludis and

Methanobacterium formicicum consisting of formate

dehydrogenase and F420-hydrogenase provide reductant to

methanogenesis and may play a role in maintaining the

redox balance during formate-growth8-11 However it has

never been shown that formate oxidation with H2 production

can be coupled to ATP generation leading to growth

We were concerned that Thermococcus onnurineus

NA1 genome contains many copies of genes coding for the

formate dehydrogenases and hydrogenases12 which might

form formate oxidizing hydrogen-evolving formate hydrogen

lyases Three copies of formate dehydrogenase genes

(fdhA) TON_0281 TON_1563 and TON_0539 are located in

three separate gene clusters and possess 48-61 amino

acid sequence identity with each other Among eight copies

of hydrogenase gene clusters three clusters were found

proximate to the formate dehydrogenase genes (Fig 1) The

functional annotation revealed that the two large gene

clusters (fdh1-mfh1-mnh1 fdh2-mfh2-mnh2) include three

modular subclusters encoding for formate dehydrogenases

multimeric membrane-bound hydrogenases and

cationproton antiporters while the small gene cluster (fdh3-

sulfI) lacks one subcluster and the hydrogenase genes code

for a cytoplasmic hydrogenase

To investigate the growth potential of T onnurineus NA1

using formate we performed anaerobic batch culturing in

media containing formate at 80degC and investigated the cell

growth and H2 production As shown in Fig 2a the strain

was able to grow efficiently by oxidation of formate as well

as to produce H2 and CO2 (mostly in the form of bicarbonate)

No growth or H2 production was detected in the control

culture lacking formate Under these conditions the actual

Gibbs energy values of the conversion of formate to H2 and

bicarbonate ranged between -8 and -20 kJmol (Fig 2b)

Therefore formate-dependent metabolism could yield

energy to support cell growth of T onnurineus NA1

although they would only allow the production of less than 1

mol ATP (ADP + Pi rarr ATP + H2O G = +70 kJmol)1314

[Figure 1] Gene organization of formate dehydrogenase gene clusters from

T onnurineus NA1

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

Methods SummaryT onnurineus NA1 was cultured in the modified

medium 120 including 35 gl NaCl 05 or 10 gl yeastextract and 10 gl sodium formate or 10 gl sulfur at80degC under anaerobic condition Cell suspensionswere prepared by washing cells with an anaerobicbuffer containing 20 mM imidazole 600 mM NaCl 30mM MgCl2 10 mM KCl 5 mM dithiothreitol pH 69 andresuspending them in the same buffer at celldensities of 1 mg protein25 ml Gases in theheadspace of serum bottles were measured with gaschromatography and formate was detected with liquidchromatography The amount of bicarbonates in theliquid was determined by measuring CO2 formed byacidifying the cell suspensions The ATP content of thecells was measured using the luciferinluciferaseassay kit Thermodynamic calculations were doneusing the Nernst equation to correct Gibbs energyvalues (G) for the actual temperature and the actualconcentrations of reactants and products The

standard Gibbs energy value (G o) was corrected toa temperature of 80oC (G o= -26 kJmol at 80oC) bylinear interpolation from tabulated values for 70 and85oC21 Activities rather than concentrations ofreactants and products were considered using theDebye-Huckel equation and they gave a negligibleeffect on Gibbs energy values (less than 027 kJmol)

A custom microarray was manufactured byRoche Nimblegen (Madison WI) Arrays werescanned using a GenePix 4000B scanner (MolecularDevices Union City CA) and the data were extractedusing NimbleScan 24 software (Roche NimbleGenMadison WI) For quantitative RT-PCR cDNAs weresynthesized from 350 ng of total RNA usingSuperScript II reverse transcriptase and PCRreactions were performed with gene-specificprimers using rTaq DNA polymerase (Takara OtsuJapan) Gene disruption was performed according tothe methods applied to a hyperthermophilicarchaeon Thermococcus kodakaraensis KOD122

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Formate-drivengrowth coupledwith H2 production

Yun Jae Kim Marine Biotechnology Research Center

bio1213hotmailcom

Although a common reaction in anaerobic

environments the conversion of formate to

bicarbonate and H2 (HCOO- + H2O HCO3- + H2 Go = +13

kJmol) has not been considered energetic enough to support

growth of microorganisms Recently experimental evidence

for growth on formate was reported for syntrophic

communities of Moorella sp strain AMP and a hydrogen-

consuming Methanothermobacter species and of

Desulfovibrio sp strain G11 and Methanobrevibacter

arboriphilus AZ1 The basis of the sustainable growth of the

formate-utilizers is explained by H2 consumption by the

methanogens which lowers the H2 partial pressure thus

making the pathway exergonic2 However it has never been

shown before that a single strain can grow on formate by

catalyzing its conversion to bicarbonate and H2 Here we

report that several hyperthermophilic archaea belonging to

the Thermococcus genus are capable of formate-oxidizing

H2-producing growth The actual G values for the formate

metabolism were calculated to range between -8 and -20

kJmol under the physiological conditions where

Thermococcus onnurineus NA1 were grown Furthermore

we detected ATP synthesis in the presence of formate as a

sole energy source Gene expression profiling and disruption

identified the gene cluster encoding formate hydrogen lyase

cationproton antiporter and formate transporter which were

responsible for growth of T onnurineus NA1 on formate This

work represents the first demonstration of formate-driven

growth by a single microorganism with protons as the

electron acceptor and demonstrates the biochemical basis of

this ability

Formate-dependent H2 production is dependent upon

formate hydrogen lyase systems composed of the

formate dehydrogenase and membrane-associated

hydrogenase3 In Escherichia coli and Thermococcus

litoralis formate is oxidized to CO2 by formate

dehydrogenase (HCOO- rarr CO2 + H+ + 2e-) and protons are

reduced to H2 by hydrogenase (2H+ + 2e- rarr H2) in response to

the accumulation of formate during fermentation to

maintain cytoplasmic pH4-7 The formate hydrogen lyase

systems in Methanococcus maripaludis and

Methanobacterium formicicum consisting of formate

dehydrogenase and F420-hydrogenase provide reductant to

methanogenesis and may play a role in maintaining the

redox balance during formate-growth8-11 However it has

never been shown that formate oxidation with H2 production

can be coupled to ATP generation leading to growth

We were concerned that Thermococcus onnurineus

NA1 genome contains many copies of genes coding for the

formate dehydrogenases and hydrogenases12 which might

form formate oxidizing hydrogen-evolving formate hydrogen

lyases Three copies of formate dehydrogenase genes

(fdhA) TON_0281 TON_1563 and TON_0539 are located in

three separate gene clusters and possess 48-61 amino

acid sequence identity with each other Among eight copies

of hydrogenase gene clusters three clusters were found

proximate to the formate dehydrogenase genes (Fig 1) The

functional annotation revealed that the two large gene

clusters (fdh1-mfh1-mnh1 fdh2-mfh2-mnh2) include three

modular subclusters encoding for formate dehydrogenases

multimeric membrane-bound hydrogenases and

cationproton antiporters while the small gene cluster (fdh3-

sulfI) lacks one subcluster and the hydrogenase genes code

for a cytoplasmic hydrogenase

To investigate the growth potential of T onnurineus NA1

using formate we performed anaerobic batch culturing in

media containing formate at 80degC and investigated the cell

growth and H2 production As shown in Fig 2a the strain

was able to grow efficiently by oxidation of formate as well

as to produce H2 and CO2 (mostly in the form of bicarbonate)

No growth or H2 production was detected in the control

culture lacking formate Under these conditions the actual

Gibbs energy values of the conversion of formate to H2 and

bicarbonate ranged between -8 and -20 kJmol (Fig 2b)

Therefore formate-dependent metabolism could yield

energy to support cell growth of T onnurineus NA1

although they would only allow the production of less than 1

mol ATP (ADP + Pi rarr ATP + H2O G = +70 kJmol)1314

[Figure 1] Gene organization of formate dehydrogenase gene clusters from

T onnurineus NA1

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

containing (2) medium cha a chaperonin-encoding gene from T onnurineus NA1

was used as a control to normalize expression levels b Growth and H2 production

of wild-type and mutant strains on formate-containing medium (mean plusmn sd n=2)

Wild-type (squares) Δƒmfh1 (circles) Δƒmfh2 (diamonds) and ΔƒsulfI (triangles)

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Formate-drivengrowth coupledwith H2 production

Yun Jae Kim Marine Biotechnology Research Center

bio1213hotmailcom

Although a common reaction in anaerobic

environments the conversion of formate to

bicarbonate and H2 (HCOO- + H2O HCO3- + H2 Go = +13

kJmol) has not been considered energetic enough to support

growth of microorganisms Recently experimental evidence

for growth on formate was reported for syntrophic

communities of Moorella sp strain AMP and a hydrogen-

consuming Methanothermobacter species and of

Desulfovibrio sp strain G11 and Methanobrevibacter

arboriphilus AZ1 The basis of the sustainable growth of the

formate-utilizers is explained by H2 consumption by the

methanogens which lowers the H2 partial pressure thus

making the pathway exergonic2 However it has never been

shown before that a single strain can grow on formate by

catalyzing its conversion to bicarbonate and H2 Here we

report that several hyperthermophilic archaea belonging to

the Thermococcus genus are capable of formate-oxidizing

H2-producing growth The actual G values for the formate

metabolism were calculated to range between -8 and -20

kJmol under the physiological conditions where

Thermococcus onnurineus NA1 were grown Furthermore

we detected ATP synthesis in the presence of formate as a

sole energy source Gene expression profiling and disruption

identified the gene cluster encoding formate hydrogen lyase

cationproton antiporter and formate transporter which were

responsible for growth of T onnurineus NA1 on formate This

work represents the first demonstration of formate-driven

growth by a single microorganism with protons as the

electron acceptor and demonstrates the biochemical basis of

this ability

Formate-dependent H2 production is dependent upon

formate hydrogen lyase systems composed of the

formate dehydrogenase and membrane-associated

hydrogenase3 In Escherichia coli and Thermococcus

litoralis formate is oxidized to CO2 by formate

dehydrogenase (HCOO- rarr CO2 + H+ + 2e-) and protons are

reduced to H2 by hydrogenase (2H+ + 2e- rarr H2) in response to

the accumulation of formate during fermentation to

maintain cytoplasmic pH4-7 The formate hydrogen lyase

systems in Methanococcus maripaludis and

Methanobacterium formicicum consisting of formate

dehydrogenase and F420-hydrogenase provide reductant to

methanogenesis and may play a role in maintaining the

redox balance during formate-growth8-11 However it has

never been shown that formate oxidation with H2 production

can be coupled to ATP generation leading to growth

We were concerned that Thermococcus onnurineus

NA1 genome contains many copies of genes coding for the

formate dehydrogenases and hydrogenases12 which might

form formate oxidizing hydrogen-evolving formate hydrogen

lyases Three copies of formate dehydrogenase genes

(fdhA) TON_0281 TON_1563 and TON_0539 are located in

three separate gene clusters and possess 48-61 amino

acid sequence identity with each other Among eight copies

of hydrogenase gene clusters three clusters were found

proximate to the formate dehydrogenase genes (Fig 1) The

functional annotation revealed that the two large gene

clusters (fdh1-mfh1-mnh1 fdh2-mfh2-mnh2) include three

modular subclusters encoding for formate dehydrogenases

multimeric membrane-bound hydrogenases and

cationproton antiporters while the small gene cluster (fdh3-

sulfI) lacks one subcluster and the hydrogenase genes code

for a cytoplasmic hydrogenase

To investigate the growth potential of T onnurineus NA1

using formate we performed anaerobic batch culturing in

media containing formate at 80degC and investigated the cell

growth and H2 production As shown in Fig 2a the strain

was able to grow efficiently by oxidation of formate as well

as to produce H2 and CO2 (mostly in the form of bicarbonate)

No growth or H2 production was detected in the control

culture lacking formate Under these conditions the actual

Gibbs energy values of the conversion of formate to H2 and

bicarbonate ranged between -8 and -20 kJmol (Fig 2b)

Therefore formate-dependent metabolism could yield

energy to support cell growth of T onnurineus NA1

although they would only allow the production of less than 1

mol ATP (ADP + Pi rarr ATP + H2O G = +70 kJmol)1314

[Figure 1] Gene organization of formate dehydrogenase gene clusters from

T onnurineus NA1

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

[Figure 1] Typical temporalwaveforms of snapping shrimpsounds produced by the threespecies of snapping shrimp

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Guided by the inhibitory activities of indole-containing natural products against isocitrate lyase (ICL)

from Candida albicans and sortase A (Srt A) from Staphylococcus aureus a series of compounds

structurally analogous to natural products were synthesized Eight Srt A inhibitors and an ICL inhibitor

having higher activities than the natural products were discovered by screening the enzyme inhibitory

activities of synthesized compounds Among the Srt A inhibitors discovered six exhibited higher activities

than p-hydroxymercuribenzoic acid which suggests that these compounds have great potential as

Guided by the inhibitory activities of indole-containing natural products against isocitrate lyase (ICL)

from Candida albicans and sortase A (Srt A) from Staphylococcus aureus a series of compounds

structurally analogous to natural products were synthesized Eight Srt A inhibitors and an ICL inhibitor

having higher activities than the natural products were discovered by screening the enzyme inhibitory

activities of synthesized compounds Among the Srt A inhibitors discovered six exhibited higher activities

than p-hydroxymercuribenzoic acid which suggests that these compounds have great potential as

alternative antibacterial agents

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Formate-drivengrowth coupledwith H2 production

Yun Jae Kim Marine Biotechnology Research Center

bio1213hotmailcom

Although a common reaction in anaerobic

environments the conversion of formate to

bicarbonate and H2 (HCOO- + H2O HCO3- + H2 Go = +13

kJmol) has not been considered energetic enough to support

growth of microorganisms Recently experimental evidence

for growth on formate was reported for syntrophic

communities of Moorella sp strain AMP and a hydrogen-

consuming Methanothermobacter species and of

Desulfovibrio sp strain G11 and Methanobrevibacter

arboriphilus AZ1 The basis of the sustainable growth of the

formate-utilizers is explained by H2 consumption by the

methanogens which lowers the H2 partial pressure thus

making the pathway exergonic2 However it has never been

shown before that a single strain can grow on formate by

catalyzing its conversion to bicarbonate and H2 Here we

report that several hyperthermophilic archaea belonging to

the Thermococcus genus are capable of formate-oxidizing

H2-producing growth The actual G values for the formate

metabolism were calculated to range between -8 and -20

kJmol under the physiological conditions where

Thermococcus onnurineus NA1 were grown Furthermore

we detected ATP synthesis in the presence of formate as a

sole energy source Gene expression profiling and disruption

identified the gene cluster encoding formate hydrogen lyase

cationproton antiporter and formate transporter which were

responsible for growth of T onnurineus NA1 on formate This

work represents the first demonstration of formate-driven

growth by a single microorganism with protons as the

electron acceptor and demonstrates the biochemical basis of

this ability

Formate-dependent H2 production is dependent upon

formate hydrogen lyase systems composed of the

formate dehydrogenase and membrane-associated

hydrogenase3 In Escherichia coli and Thermococcus

litoralis formate is oxidized to CO2 by formate

dehydrogenase (HCOO- rarr CO2 + H+ + 2e-) and protons are

reduced to H2 by hydrogenase (2H+ + 2e- rarr H2) in response to

the accumulation of formate during fermentation to

maintain cytoplasmic pH4-7 The formate hydrogen lyase

systems in Methanococcus maripaludis and

Methanobacterium formicicum consisting of formate

dehydrogenase and F420-hydrogenase provide reductant to

methanogenesis and may play a role in maintaining the

redox balance during formate-growth8-11 However it has

never been shown that formate oxidation with H2 production

can be coupled to ATP generation leading to growth

We were concerned that Thermococcus onnurineus

NA1 genome contains many copies of genes coding for the

formate dehydrogenases and hydrogenases12 which might

form formate oxidizing hydrogen-evolving formate hydrogen

lyases Three copies of formate dehydrogenase genes

(fdhA) TON_0281 TON_1563 and TON_0539 are located in

three separate gene clusters and possess 48-61 amino

acid sequence identity with each other Among eight copies

of hydrogenase gene clusters three clusters were found

proximate to the formate dehydrogenase genes (Fig 1) The

functional annotation revealed that the two large gene

clusters (fdh1-mfh1-mnh1 fdh2-mfh2-mnh2) include three

modular subclusters encoding for formate dehydrogenases

multimeric membrane-bound hydrogenases and

cationproton antiporters while the small gene cluster (fdh3-

sulfI) lacks one subcluster and the hydrogenase genes code

for a cytoplasmic hydrogenase

To investigate the growth potential of T onnurineus NA1

using formate we performed anaerobic batch culturing in

media containing formate at 80degC and investigated the cell

growth and H2 production As shown in Fig 2a the strain

was able to grow efficiently by oxidation of formate as well

as to produce H2 and CO2 (mostly in the form of bicarbonate)

No growth or H2 production was detected in the control

culture lacking formate Under these conditions the actual

Gibbs energy values of the conversion of formate to H2 and

bicarbonate ranged between -8 and -20 kJmol (Fig 2b)

Therefore formate-dependent metabolism could yield

energy to support cell growth of T onnurineus NA1

although they would only allow the production of less than 1

mol ATP (ADP + Pi rarr ATP + H2O G = +70 kJmol)1314

[Figure 1] Gene organization of formate dehydrogenase gene clusters from

T onnurineus NA1

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Formate-drivengrowth coupledwith H2 production

Yun Jae Kim Marine Biotechnology Research Center

bio1213hotmailcom

Although a common reaction in anaerobic

environments the conversion of formate to

bicarbonate and H2 (HCOO- + H2O HCO3- + H2 Go = +13

kJmol) has not been considered energetic enough to support

growth of microorganisms Recently experimental evidence

for growth on formate was reported for syntrophic

communities of Moorella sp strain AMP and a hydrogen-

consuming Methanothermobacter species and of

Desulfovibrio sp strain G11 and Methanobrevibacter

arboriphilus AZ1 The basis of the sustainable growth of the

formate-utilizers is explained by H2 consumption by the

methanogens which lowers the H2 partial pressure thus

making the pathway exergonic2 However it has never been

shown before that a single strain can grow on formate by

catalyzing its conversion to bicarbonate and H2 Here we

report that several hyperthermophilic archaea belonging to

the Thermococcus genus are capable of formate-oxidizing

H2-producing growth The actual G values for the formate

metabolism were calculated to range between -8 and -20

kJmol under the physiological conditions where

Thermococcus onnurineus NA1 were grown Furthermore

we detected ATP synthesis in the presence of formate as a

sole energy source Gene expression profiling and disruption

identified the gene cluster encoding formate hydrogen lyase

cationproton antiporter and formate transporter which were

responsible for growth of T onnurineus NA1 on formate This

work represents the first demonstration of formate-driven

growth by a single microorganism with protons as the

electron acceptor and demonstrates the biochemical basis of

this ability

Formate-dependent H2 production is dependent upon

formate hydrogen lyase systems composed of the

formate dehydrogenase and membrane-associated

hydrogenase3 In Escherichia coli and Thermococcus

litoralis formate is oxidized to CO2 by formate

dehydrogenase (HCOO- rarr CO2 + H+ + 2e-) and protons are

reduced to H2 by hydrogenase (2H+ + 2e- rarr H2) in response to

the accumulation of formate during fermentation to

maintain cytoplasmic pH4-7 The formate hydrogen lyase

systems in Methanococcus maripaludis and

Methanobacterium formicicum consisting of formate

dehydrogenase and F420-hydrogenase provide reductant to

methanogenesis and may play a role in maintaining the

redox balance during formate-growth8-11 However it has

never been shown that formate oxidation with H2 production

can be coupled to ATP generation leading to growth

We were concerned that Thermococcus onnurineus

NA1 genome contains many copies of genes coding for the

formate dehydrogenases and hydrogenases12 which might

form formate oxidizing hydrogen-evolving formate hydrogen

lyases Three copies of formate dehydrogenase genes

(fdhA) TON_0281 TON_1563 and TON_0539 are located in

three separate gene clusters and possess 48-61 amino

acid sequence identity with each other Among eight copies

of hydrogenase gene clusters three clusters were found

proximate to the formate dehydrogenase genes (Fig 1) The

functional annotation revealed that the two large gene

clusters (fdh1-mfh1-mnh1 fdh2-mfh2-mnh2) include three

modular subclusters encoding for formate dehydrogenases

multimeric membrane-bound hydrogenases and

cationproton antiporters while the small gene cluster (fdh3-

sulfI) lacks one subcluster and the hydrogenase genes code

for a cytoplasmic hydrogenase

To investigate the growth potential of T onnurineus NA1

using formate we performed anaerobic batch culturing in

media containing formate at 80degC and investigated the cell

growth and H2 production As shown in Fig 2a the strain

was able to grow efficiently by oxidation of formate as well

as to produce H2 and CO2 (mostly in the form of bicarbonate)

No growth or H2 production was detected in the control

culture lacking formate Under these conditions the actual

Gibbs energy values of the conversion of formate to H2 and

bicarbonate ranged between -8 and -20 kJmol (Fig 2b)

Therefore formate-dependent metabolism could yield

energy to support cell growth of T onnurineus NA1

although they would only allow the production of less than 1

mol ATP (ADP + Pi rarr ATP + H2O G = +70 kJmol)1314

[Figure 1] Gene organization of formate dehydrogenase gene clusters from

T onnurineus NA1

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

was used as a control to normalize expression levels b Growth and H2 production

of wild-type and mutant strains on formate-containing medium (mean plusmn sd n=2)

Wild-type (squares) Δƒmfh1 (circles) Δƒmfh2 (diamonds) and ΔƒsulfI (triangles)

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

Methods SummaryT onnurineus NA1 was cultured in the modified

medium 120 including 35 gl NaCl 05 or 10 gl yeastextract and 10 gl sodium formate or 10 gl sulfur at80degC under anaerobic condition Cell suspensionswere prepared by washing cells with an anaerobicbuffer containing 20 mM imidazole 600 mM NaCl 30mM MgCl2 10 mM KCl 5 mM dithiothreitol pH 69 andresuspending them in the same buffer at celldensities of 1 mg protein25 ml Gases in theheadspace of serum bottles were measured with gaschromatography and formate was detected with liquidchromatography The amount of bicarbonates in theliquid was determined by measuring CO2 formed byacidifying the cell suspensions The ATP content of thecells was measured using the luciferinluciferaseassay kit Thermodynamic calculations were doneusing the Nernst equation to correct Gibbs energyvalues (G) for the actual temperature and the actualconcentrations of reactants and products The

standard Gibbs energy value (G o) was corrected toa temperature of 80oC (G o= -26 kJmol at 80oC) bylinear interpolation from tabulated values for 70 and85oC21 Activities rather than concentrations ofreactants and products were considered using theDebye-Huckel equation and they gave a negligibleeffect on Gibbs energy values (less than 027 kJmol)

A custom microarray was manufactured byRoche Nimblegen (Madison WI) Arrays werescanned using a GenePix 4000B scanner (MolecularDevices Union City CA) and the data were extractedusing NimbleScan 24 software (Roche NimbleGenMadison WI) For quantitative RT-PCR cDNAs weresynthesized from 350 ng of total RNA usingSuperScript II reverse transcriptase and PCRreactions were performed with gene-specificprimers using rTaq DNA polymerase (Takara OtsuJapan) Gene disruption was performed according tothe methods applied to a hyperthermophilicarchaeon Thermococcus kodakaraensis KOD122

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Mechanism for formate-driven growth

Formate-driven growth coupled with H2 productionYun Jae Kim I Hyun Sook Lee I Jung-Hyun Lee I Sung Gyun Kang

[ NATURE I VOL46716 September 2010 ]

Page 7: KORDI, in quest of the world’s best ocean science and technology! · 2020-05-06 · KORDI S&T 발행인: 강정극 기획·편집: 성과확산팀 디자인: 모모새비지니스

To test this hypothesis H2 production and ATP content

were monitored upon the addition of formate to the cell

suspensions of T onnurineus NA1 in the absence of any other

exogenous energy source Indeed ATP was newly

synthesized upon the addition of formate to the cell

suspensions (Fig 3) No ATP production was detected in a

control lacking formate (data not shown) Each mole of

formate consumption led to the production of one mole of

CO2 and one mole of H2 The production of other gases

formed during well established anaerobic respirations such

as CH4 CO or H2S was not detected Thus the detection of

ATP biosynthesis in response to the addition of formate

provided strong evidence that formate-dependent proton

reduction could conserve energy in T onnurineus NA1

To identify the gene cluster to which the growth on

formate is attributed gene expression profiling of three

formate dehydrogenase gene clusters of T onnurineus NA1

was performed using a DNA microarray Relative expression

ratios were derived by comparing mRNA abundance levels in

cells grown on medium containing formate alone relative to

those in cells grown on sulfur-containing medium The

largest changes were found in the fdh2-mfh2-mnh2 gene

cluster with 72 (1318) of the genes up-regulated more

than two-fold (Fig 4) On the other hand the fdh1-mfh1-

mnh1 and fdh3-sulfI gene clusters were only slightly down-

and up-regulated respectively

Depending on the subcellular localization of formate

dehydrogenase a formate transporter can be a prerequisite

for growth on formate In T onnurineus NA1 three sets of

formate dehydrogenase proteins were predicted to be

localized in the cytoplasm by using PSORTb and TMHMM

online software1516 We searched therefore the genome

sequence of T onnurineus NA1 for formate transporter

genes and found two separate genes TON_1573 and

TON_0538 in fdh2-mfh2-mnh2 and fdh3-sulfI gene clusters

respectively TON_1573 and TON_0538 were 56 identical

The transcriptomic analysis showed that transcription of

TON_1573 was strongly up-regulated by 4-fold when formate

was supplied while TON_0538 was slightly down-regulated

13-fold indicating that only TON_1573 contributes to growth

on formate

The relative importance of the fdh2-mfh2-mnh2 gene

cluster for growth on formate was assessed by quantitative

RT-PCR and gene disruption of the large subunits of the

hydrogenases mfh1 mfh2 and sulfI (data not shown)

suggesting that the hydrogenase encoded by mfh2 is solely

responsible for growth on exogenous formate

Based on the gene organization of the fdh2-mfh2-mnh2

gene cluster we propose a mechanism for the coupling of

formate oxidation to energy conservation in T onnurineus

NA1 (Fig 5) We hypothesize that a formate transporter

imports formate into the cytoplasm and the formate

hydrogen lyase complex (composed of formate

dehydrogenase (Fdh2) and hydrogenase (Mfh2)) mediates

electrogenic H+-translocation during formate oxidation The

putative cationproton antiporter may be involved in the

transformation of the proton gradient to a sodium gradient

which is utilized for ATP synthesis An understanding of the

mechanism involved in the coupling of formate oxidation to

the energy conservation will have to await the determination

of the roles of the components in the gene cluster17-19

In summary this work presents the first evidence for the

ability of a single microorganism alone to grow on formate

along with H2 evolution and ATP generation via a formate

dehydrogenase and an energy-conserving hydrogenase As

such it represents one of the simplest anaerobic respirations

described so far

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Methods SummaryT onnurineus NA1 was cultured in the modified

medium 120 including 35 gl NaCl 05 or 10 gl yeastextract and 10 gl sodium formate or 10 gl sulfur at80degC under anaerobic condition Cell suspensionswere prepared by washing cells with an anaerobicbuffer containing 20 mM imidazole 600 mM NaCl 30mM MgCl2 10 mM KCl 5 mM dithiothreitol pH 69 andresuspending them in the same buffer at celldensities of 1 mg protein25 ml Gases in theheadspace of serum bottles were measured with gaschromatography and formate was detected with liquidchromatography The amount of bicarbonates in theliquid was determined by measuring CO2 formed byacidifying the cell suspensions The ATP content of thecells was measured using the luciferinluciferaseassay kit Thermodynamic calculations were doneusing the Nernst equation to correct Gibbs energyvalues (G) for the actual temperature and the actualconcentrations of reactants and products The

standard Gibbs energy value (G o) was corrected toa temperature of 80oC (G o= -26 kJmol at 80oC) bylinear interpolation from tabulated values for 70 and85oC21 Activities rather than concentrations ofreactants and products were considered using theDebye-Huckel equation and they gave a negligibleeffect on Gibbs energy values (less than 027 kJmol)

A custom microarray was manufactured byRoche Nimblegen (Madison WI) Arrays werescanned using a GenePix 4000B scanner (MolecularDevices Union City CA) and the data were extractedusing NimbleScan 24 software (Roche NimbleGenMadison WI) For quantitative RT-PCR cDNAs weresynthesized from 350 ng of total RNA usingSuperScript II reverse transcriptase and PCRreactions were performed with gene-specificprimers using rTaq DNA polymerase (Takara OtsuJapan) Gene disruption was performed according tothe methods applied to a hyperthermophilicarchaeon Thermococcus kodakaraensis KOD122

Methods SummaryT onnurineus NA1 was cultured in the modified

medium 120 including 35 gl NaCl 05 or 10 gl yeastextract and 10 gl sodium formate or 10 gl sulfur at80degC under anaerobic condition Cell suspensionswere prepared by washing cells with an anaerobicbuffer containing 20 mM imidazole 600 mM NaCl 30mM MgCl2 10 mM KCl 5 mM dithiothreitol pH 69 andresuspending them in the same buffer at celldensities of 1 mg protein25 ml Gases in theheadspace of serum bottles were measured with gaschromatography and formate was detected with liquidchromatography The amount of bicarbonates in theliquid was determined by measuring CO2 formed byacidifying the cell suspensions The ATP content of thecells was measured using the luciferinluciferaseassay kit Thermodynamic calculations were doneusing the Nernst equation to correct Gibbs energyvalues (G) for the actual temperature and the actualconcentrations of reactants and products The

standard Gibbs energy value (G o) was corrected toa temperature of 80oC (G o= -26 kJmol at 80oC) bylinear interpolation from tabulated values for 70 and85oC21 Activities rather than concentrations ofreactants and products were considered using theDebye-Huckel equation and they gave a negligibleeffect on Gibbs energy values (less than 027 kJmol)

A custom microarray was manufactured byRoche Nimblegen (Madison WI) Arrays werescanned using a GenePix 4000B scanner (MolecularDevices Union City CA) and the data were extractedusing NimbleScan 24 software (Roche NimbleGenMadison WI) For quantitative RT-PCR cDNAs weresynthesized from 350 ng of total RNA usingSuperScript II reverse transcriptase and PCRreactions were performed with gene-specificprimers using rTaq DNA polymerase (Takara OtsuJapan) Gene disruption was performed according tothe methods applied to a hyperthermophilicarchaeon Thermococcus kodakaraensis KOD122

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

Methods SummaryT onnurineus NA1 was cultured in the modified

medium 120 including 35 gl NaCl 05 or 10 gl yeastextract and 10 gl sodium formate or 10 gl sulfur at80degC under anaerobic condition Cell suspensionswere prepared by washing cells with an anaerobicbuffer containing 20 mM imidazole 600 mM NaCl 30mM MgCl2 10 mM KCl 5 mM dithiothreitol pH 69 andresuspending them in the same buffer at celldensities of 1 mg protein25 ml Gases in theheadspace of serum bottles were measured with gaschromatography and formate was detected with liquidchromatography The amount of bicarbonates in theliquid was determined by measuring CO2 formed byacidifying the cell suspensions The ATP content of thecells was measured using the luciferinluciferaseassay kit Thermodynamic calculations were doneusing the Nernst equation to correct Gibbs energyvalues (G) for the actual temperature and the actualconcentrations of reactants and products The

standard Gibbs energy value (G o) was corrected toa temperature of 80oC (G o= -26 kJmol at 80oC) bylinear interpolation from tabulated values for 70 and85oC21 Activities rather than concentrations ofreactants and products were considered using theDebye-Huckel equation and they gave a negligibleeffect on Gibbs energy values (less than 027 kJmol)

A custom microarray was manufactured byRoche Nimblegen (Madison WI) Arrays werescanned using a GenePix 4000B scanner (MolecularDevices Union City CA) and the data were extractedusing NimbleScan 24 software (Roche NimbleGenMadison WI) For quantitative RT-PCR cDNAs weresynthesized from 350 ng of total RNA usingSuperScript II reverse transcriptase and PCRreactions were performed with gene-specificprimers using rTaq DNA polymerase (Takara OtsuJapan) Gene disruption was performed according tothe methods applied to a hyperthermophilicarchaeon Thermococcus kodakaraensis KOD122

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

As a continuous effort of developing highly enantioselective epoxide hydrolase from marine

microorganisms it was found that Rhodobacterales bacterium HTCC2654 was highly enantioselective

toward racemic Glycidyl Phenyl Ether (GPE) An Open Reading Frame (ORF) encoding a putative Epoxide

Hydrolase (EHase) was cloned from the genome of R bacterium HTCC2654 followed by expression and

purification in Escherichiacoli The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE

Enantiopure (R)-GPE from kinetic resolution of 292 mM racemic GPE using the purified REH could be

obtained with enantiopurity of more than 999 enantiomeric excess (ee) and 384 yield (theoretical 50)

within 20 min (enantiomeric ratio (E-value) 384) The enantioselective activity of REH toward GPE was also

confirmed by the analysis of the vicinal diol 3-phenoxy-12-propanediol To our knowledge this study

demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the

known native EHases

Amplified polar warming and moistening under global warming are critical issues for the climate

changes The authors find that a poleward shift of the westerly jet stream and associated synoptic eddy

feedback play a critical role in enhancing polar warming and moistening Namely the mean circulation

changes due to anthropogenic forcing lead to the changes in storm feedbacks which reinforce again

climate responses particularly the polar responses such as the enhanced polar warming and moistening It

is demonstrated here that the storm feedback can be explained by a simple rule based on the mean

circulation change This rule can be used for understanding other regional climate responses to the

anthropogenic forcing

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

[Figure 2] Normalized spectra ofsounds produced by the threespecies of snapping shrimp

[Figure 3] Normalized spectra ofsounds produced by the speciesA lobidens with different clawlengths

The typical temporal waveforms and spectra of the sounds produced by the three species of snapping

shrimp with different claw shapes and almost the same claw lengths were investigated under laboratory

conditions The sound spectra generated by one species of snapping shrimp were also investigated for

various claw lengths For the three species of snapping shrimp their typical temporal waveforms were

similar but their sound spectra and pulse durations differed This difference was related to the size of the

single cavitation bubble which was generated by the high-speed water jet emitted from the snapping

shrimp claw The range of difference in the times between the snapping shrimp claw closure and the

collapse of the single cavitation bubble for the three species of snapping shrimp seemed to be determined

by the difference in the claw shape The collapse time the equilibrium radius and the maximal radius of the

cavitation bubble for each species were estimated from the first peak frequency component in the snapping

shrimp sound spectrum For one species of snapping shrimp the peak frequency components in the sound

spectra were observed for various claw lengths and their superposition could be considered as the cause

that the broad peak frequency components were variously observed in the averaged snapping shrimp sound

spectra which were measured in many shallow water areas

A numerical method which combines the Boundary Element Method (BEM) and the Volume Of the

Fluid method (VOF method) has been presented to solve wave-structure interactions the intense wave

motion at the proximity of the structure is modeled by the VOF method and the rest of the fluid region is

modeled by the BEM The combined method can considerably reduce the time-consuming VOF domain and

thus practically makes it possible to apply the VOF method for random wave calculations in which long

time computations are usually required to obtain statistically meaningful results and therefore the use of

the single-VOF model often becomes prohibitive in terms of computational time and storage memories A

VOF model CADMAS-SURF which is based on SMAC scheme and had been constructed by a number of VOF

researchers in coastal engineering in Japan is used in the combined BEM-VOF model The two-way

coupling treatment which enables us to deal with bidirectional wave propagations which was originally

given for the SOLA-VOF model by Yan et al (2003a) and later improved by Kim et al (2007) was modified for

the SMAC scheme The coupling treatments are described in detail in the paper The validity of the

combined BEM-VOF model was investigated by comparing the numerical results with the theoretical

results for the propagations of Stokes 5th order waves and random waves

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

A two-frame Particle Image Velocimetry (PIV) technique was used to investigate the flow

characteristics of a complicated propeller wake influenced by a hull wake As the propeller is significantly

affected by the hull wake of a marine vessel measurements of the propeller wake under the hull wake are

certainly needed for more reliable validation of numerical predictions Velocity field measurements were

conducted in a cavitation tunnel with a simulated hull wake Generally the hull wake generated by the hull

of a marine ship may cause different loading distributions on the propeller blade in both the upper and the

lower propeller planes The unstable propeller wake caused by the shiprsquos hull was interpreted in terms of

Turbulent Kinetic Energy (TKE) to obtain useful information for flow modeling The unstable or unsteady

phenomenon in the upper propeller wake was identified by using the Proper Orthogonal Decomposition

(POD) method to characterize the coherent flow structure with turbulent kinetic energy Strong

unsteadiness appeared in the second and higher modes largely affecting the downstream flow

characteristics The first eigenmode can be used to appropriately identify the tip vortex positions even in the

unstable downstream region which are helpful for establishing reliable wake modeling

The electrical resistivity of soil having different Chemical Weathering Index(CWI) was measured and

the correlation between CWI and the electrical resistivity was estimated The electrical resistivity of soil

varies with CWI of soil The difference in the electrical resistivities of soils having different weathering

degrees is clear at lower water contents At the volumetric water contents estimated in this study CWI

could be described by a linear equation of electrical resistivity with the constants related to the volumetric

water content The findings in this study suggest that the electrical resistivity could be used as an effective

alternative for estimating the weathering degree of soil

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Compensatory growth and proximate composition of dark-banded rockfish(mean weight 136 g) were

examined after fish had experienced five different prefeeding regimes over a 7-week period Fish were fed

at 0 (R0) 25 (R25) 50 (R50) 75 (R75) and 100 (R100 control) satiation for 2 weeks before satiation

feeding for 5 weeks Fish of R50 and R75 achieved the same body weight as the control fish after satiation

feeding for 5 and 2 weeks respectively Although the specific growth rate and feed efficiency of R0 and R25

fish were higher than those of the control fish during the first 3 weeks of satiation feeding fish in these

tanks did not catch-up with the body weight of the control fish at the end of the 5 week At Week 2 and Week

7 the lipid ratios to the body mass of R0 R25 and R50 fish were significantly lower than those of the control

fish but there was no difference between the control and R75 fish This result suggests that the fish

subjected to a prerestricted feeding regime of 50-75 satiation feeding for 2 weeks result in complete

compensatory growth while the fish experiencing more severe feed restriction (0-25 satiation) only show

partial compensatory growth capacity

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

from Candida albicans and sortase A (Srt A) from Staphylococcus aureus a series of compounds

structurally analogous to natural products were synthesized Eight Srt A inhibitors and an ICL inhibitor

having higher activities than the natural products were discovered by screening the enzyme inhibitory

activities of synthesized compounds Among the Srt A inhibitors discovered six exhibited higher activities

than p-hydroxymercuribenzoic acid which suggests that these compounds have great potential as

alternative antibacterial agents

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

High spatial resolution satellite data (IKONOS) combined with in situ data was used to quantitatively

estimate the spatial distribution of tidal flat surface sedimentary facies for the Hwangdo tidal flat Cheonsu

Bay Korea The classification result was accurate in terms of a comparison with the in situ data and the

overall accuracy was 907 which confirmed the validity of the classification GIS analysis based on a

probabilistic model was applied to a quantitative estimation of the relationship between each surface

sedimentary facies and the spectral reflectance Mud flat facies showed a high positive correlation (R2 =

091) and sand flat facies showed a high negative correlation (R2 = 100) which was a good reflection of the

sedimentary characteristics of Hwangdo tidal flat Relationships between each sedimentary facies and DEM

also showed good agreement with the topographic characteristics in the study area The study revealed that

tidal flat surface sediment classification using high resolution remote sensing imagery and in situ data

successfully shows spectral and topographic characteristics of the study area It was noted that spectral

reflectance was affected by a combination of environmental factors including grain size topography and

remnant surface water It is possible to determine the type of tidal flat through quantitative estimates of the

spatial distribution of surface sediments according to their spectral reflectance

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Effects of screening a hydrophone with open-cell foams are determined to reduce the level of

infrasonic background noise which is the self-noise probably induced by the presence of flow around the

hydrophone in shallow and deep seas The result obtained in shallow sea with bottommounted geometry

shows that the level of background noise could be reduced by more than 20 dB below 10 Hz if the

hydrophone is screened Also the result of ship noise measurement conducted in deep sea with drifting

geometry shows that a maximum background noise reduction of 15 dB could be achieved in the infrasonic

band without affecting the true acoustic signals

Guided by the inhibitory activities of indole-containing natural products against isocitrate lyase (ICL)

from Candida albicans and sortase A (Srt A) from Staphylococcus aureus a series of compounds

structurally analogous to natural products were synthesized Eight Srt A inhibitors and an ICL inhibitor

having higher activities than the natural products were discovered by screening the enzyme inhibitory

activities of synthesized compounds Among the Srt A inhibitors discovered six exhibited higher activities

than p-hydroxymercuribenzoic acid which suggests that these compounds have great potential as

alternative antibacterial agents

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

Hydrogenases are the key enzymes involved in the metabolism of H2 catalyzing the chemical reaction

2H+ + 2e- H2 Three genes encoding Group 4 [NiFe]-hydrogenases from Thermococcus onnurineus NA1

were found to be organized into three separate gene clusters fdh1-mfh1-mnh1 fdh2-mfh2-mnh2 and

codh-mch-mnh3 (Figure 1) The open reading frames in the clusters can be divided into three-modules of

dehydrogenase-hydrogenase-cationproton antiporter subunits Phylogenetic analysis of the large subunits

of all the target hydrogenases revealed that the target hydrogenases grouped together in a separate cluster

4b in Group 4 (Figure 2) By sequence alignment of subgroup 4b hydrogenases a pair of highly conserved

motifs (L1 and L2) were revealed which represent two regions surrounding the two pairs of cysteine ligands

of the NiFe center of the large subunits of hydrogenases (Figure 3) Biochemical and physiological

experiments could assess the roles of the novel hydrogenases and other components of the tripartite

clusters

Lon proteases are distributed in all kingdoms of life and are required for survival of cells under stress

Lon is a tandem fusion of an AAA+ molecular chaperone and a protease with a serine-lysine catalytic dyad

We report the 20-Å resolution crystal structure of Thermococcus onnurineus NA1 Lon (TonLon) The

structure is a three-tiered hexagonal cylinder with a large sequestered chamber accessible via an axial

channel Conserved loops extending from the AAA+ domain combine with an insertion domain containing

the membrane anchor to form an apical domain that serves as a gate governing substrate access to an

internal unfolding and degradation chamber Alternating AAA+ domains are in tight- and weak-binding

nucleotide states with different domain orientations and intersubunit contacts reflecting intramolecular

dynamics during ATP-driven protein unfolding and translocation The bowl-shaped proteolytic chamber is

contiguous with the chaperone chamber allowing internalized proteins direct access to the proteolytic sites

without further gating restrictions

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively

In the present study the protective effect of diphlorethohydroxycarmalol (DPHC) isolated from Ishige

okamurae a brown algae on high glucose-induced-oxidative stress was investigated using human

umbilical vein endothelial cells (HUVECs) High concentration of glucose (30 mM) treatment induced

cytotoxicity whereas DPHC prevented cells from high glucose-induced damage restoring cell viability was

significantly increased In addition the lipid peroxidation intracellular Reactive Oxygen Species (ROS) and

Nitric Oxide (NO) levels induced by high glucose treatment were effectively inhibited by addition of DPHC in

a dose-dependent manner DPHC also suppressed the over-expressions of Inducible Nitric Oxide Synthase

(iNOS) and cyclooxygenase-2 (COX-2) proteins as well as nuclear factor-kappa B (NF-KB) activation induced

by high glucose in HUVECs These finding indicate that DPHC might be used as potential pharmaceutical

agent which will reduce the damage caused by high glucose-induced-oxidative stress associated with

diabetes

Polybrominateddiphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are potentially toxic and

persistent anthropogenic chemicals PBDEs are a class of brominated flame-retardants that are used in

the plastics electronic circuitry television sets building materials and textiles PCBs has been widely used

for industrial applications such as dielectric fluids in capacitors and transformers print inks paints

pesticidesdue to their chemical and physical stability Stockholm Convention recognized them as priority

persistent organic compounds for cautious regulation in the world In this study congener specific

determination of PBDEs and PCBs was carried out in 24 surface sediment samples and a sediment core

from Masan Bay Korea Among the 40 PBDE congeners targeted only 29 were detectable PBDE congener

profile within sediments was dominated by BDE-209 followed by BDEs-99 -47 -153 and -183 sequentially

which reflects well the dominant usage of Deca-BDE commercial mixture in Korea In surface sediments

the average PBDEs levels approached that of average PCBs values However trends observed in the

sediment core suggest that this pattern will alter over time and result in higher surface sediment PBDE

concentrations than PCBs in the future Various diffuse and point sources were identified for PBDEs and

PCBs in this location Shipping and other industrial activities were associated with PCB contamination while

domestic and industrial waste discharges corresponded with PBDE contamination The average

concentration for PBDEs and PCBs in surface sediments were 57 72 ngg dry weight respectively
