Class Rules• Disruptive behavior will not be tolerated. That includes talking, sleeping, and

tardiness.

• Do not text or use your cell phone while class/lab is in session. If you must be available during an emergency I request that you notify me before class or lab begins. If I notice you texting then you are likely disrupting other students.

• Phones are to be turned off and put away during quizzes and exams.

• There will be no eating or drinking in the lab. Students are not allowed to bring in any food or drinks. People who bring food and drinks into the lab will be asked to leave. This is an OSHA requirement.

• Students are expected to treat fellow students and staff members with respect.

• OCTC has a zero tolerance rule with regards to fighting and threatening other students or staff. That will include inappropriate e-mails. They will be reported.

• Students are expected to check their email, BlackBoard and the LSA website often.

Attendance

•Students are expected to attend and be on time for each and every class. •In order for you to learn, you must be present.

• The attendance and tardy policies and procedures will be the same as your home high school.

•The expectation is that you are in the classroom, willing and ready to learn each day.

•This class is fun but it is also challenging. If you miss class, you will get behind.

• When your home school activities conflict with LSA we will work with you on an individual basis.

• Much of what we do is team-based - you will be missed by your group when you are not in class!

Pay AttentionStudents must carefully follow instructions on all assignments, exams, etc.

experiment dealt with enzyme amylase and trypsin

Question: What conclusions can you draw from the protein digestion experiment? (Your answer must refer to the enzyme and molecule involves. Answer in complete sentences)

Answer: This experiment tells me that noone of the amino acid bonds in ay of test tubes were broken.

Question: What conclusions can you draw from the protein digestion experiment? (Your answer must refer to the enzyme and molecule involves. Answer in complete sentences)

Answer: solution was clear yellow tint appeared in the tubes that were left in room temp. These made the glucose reading positive for the ones at room temperature and negative reading for the ones in the hot water.

Late WorkHomework, projects, labs, etc. are due at the beginning of class on the assigned day.

I will not accept late work from students unless they have an excused absence.

It is your responsibility to retrieve the work you missed. You may email me to get missed assignments.

Labs cannot be made up. If you miss a lab, a make-up assignment will be given in its place even if you have an excused absence.

Unit 1 The Mystery Infection - Overview

In the opening lesson, you will be exposed to interventions involved in detecting, fighting, and preventing an infectious disease as they investigate a potential outbreak at a fictitious college.

Sue Smith, a freshman in college, is not feeling well. She thinks she just has a cold, but further investigation will reveal something far more serious. You will use various techniques and technologies to diagnose Sue and determine the source of the disease on campus. You will analyze clues found in the history and physical examination of each possible patient, identify pathogens present in body fluids through DNA sequence analysis, and test for the infectious agent using the antibody-based Enzyme-linked Immunosorbant Assay (ELISA).

You will be introduced to the field of bioinformatics as you explore genetic databases to identify known gene sequences. You will also review principles of human immunity as you learn how antibodies can be used to identify the presence of a disease agent.

At the conclusion of the investigation, you will outline a plan to stop a potential outbreak on campus and discuss interventions such as antibiotic therapy and vaccination, two topics to be explored in greater detail in the subsequent lessons.

Unit 1 The Mystery Infection - Overview

Understandings• Medical interventions help maintain health and homeostasis in the body.• A variety of methods can be used to detect and/or identify infectious agents.

Knowledge and SkillsIt is expected that you will:• Recognize that medical interventions are measures to improve health or alter the course of an

illness and can be used to prevent, diagnose, and treat disease.• Describe how bioinformatics, the collection, classification, storage, and analysis of biochemical and

biological information using computers, can be used to identify disease pathogens.• Describe the applications of bioinformatics in health and wellness.• Recognize that diagnostic tests for infectious diseases can provide qualitative results, indicating the

presence or absence of disease, as well as quantitative results, indicating the concentration of the infectious agent or of an antibody produced in response to the disease agent.

• Explain the principles of the Enzyme-linked Immunosorbant Assay (ELISA) test and describe how antibodies can be used to detect disease.

• Analyze connections between individuals in a disease outbreak.• Use publically available molecular databases to search for DNA sequences and identify pathogens.• Compute serial dilutions and calculate resultant concentrations.• Perform ELISA testing to determine the concentration of infectious bacteria in simulated body fluids

and identify infected patients.

KEY TERMS


What is a medical intervention?

Unit 1 - How to Fight InfectionActivity 1.1.1 Intervention InventoryIntroduction

Look around. Someone in the class is probably wearing glasses or contact lenses. Most likely someone in your school is sporting a cast or using crutches. Maybe you took an aspirin this morning for a raging headache or chugged a sports drink after your morning workout. In some way, each of these devices, medications or treatments, helped people improve their quality of life. Medical interventions are any measure whose purpose is to improve health or alter the course of a disease. Unless faced with a serious illness or injury, we often forgot about the variety of medical interventions that function to keep us well. Medicine is changing at a rapid pace. Many diseases that were lethal hundreds of years ago can now be controlled or even cured. New devices, medications, procedures, and tests help to extend and improve our quality of life. In both Principles of the Biomedical Sciences and Human Body Systems, you examined interventions related to specific illnesses or diseases. In this course, you will explore medical interventions of the past, present, and even the future.

Unit 1 - How to Fight InfectionActivity 1.1.1 Intervention InventoryGoal:

In this activity, you will brainstorm the vast array of medical interventions, big and small, new and old, which function to maintain health and homeostasis in our bodies. You will then work with your team to organize your ideas and group these interventions into categories. This year, you will become acquainted with the members of the Smith family. Their stories will introduce you to modern medical interventions as well as help you visualize the future of medicine. As you follow their family, through good times and bad, be on the lookout for medical interventions.

Outbreak Assessment:

Who is patient zero on campus? Sue

How did this disease spread on campus?• One possible hypothesis: Sue brought the bacteria back from her visit to the

other college

• Jill lives with Sue and plays on the same sports team, they share many cups, utensils and water bottles.

• Either Jill or Sue passed the infection to Maria, who is always in their room.

• Sue had lab with Marco. They may have shared a soda during the break and had other contact leading to transmission of the bacterium


Outbreak Assessment:

What is the appropriate treatment? Use antibiotics to treat those infected

What other medical interventions should be used?• Provide the bacterial meningitis vaccine to those who are unaffected• Test other students at the college that Sue visited
