Biology Case Study

/in /by

 

  1. SCIENCE:  what exactly happened genetically (do not list symptoms) to the the first generation women when they were given the DES?   EXPLAIN.

 

  1.  LEGAL :  could any of these groups  SUE?

which ones?
WHAT SHOULD the argument be if they sue?
Who would  win? WHY?
What should the settlement be (not just money)?
What group should have stepped in and stopped this? and HOW?

  1. ETHICAL: Were the doctors who gave this to women responsible for what happened to them and subsequent generations?  WHY or WHY NOT?
  2. Why did these women take an unknown substance?
  3. This has happened very few times in medical history.  Find one example that has happened recently and tell me about it
  4. A new area of genetics called EPIGENETICS (page 134) has recently given an explanation about what might have happened.  What is epigenetics and how does it fit into the case?

 

  1.  future of DES.  Do you think this could go on for many generations in the future.  EXPLAIN.

 
8 find a family  that has been affected by DES and write their story.
 

  1. the worst thing about this is it will follow generations and we aren’t sure how it will affect them. Look at the chart and make a prediction what you think happen in the future.

 
There is a chart, reading and information about all generations on page 141 but the questions above need research to answer, and I am attaching it here.

Background:
Visit http://highered.mheducation.com/sites/0073403490/information_center_view0/index.html and choose the Students edition tab at the left side of the page (you don’t need to sign in). Click on Chapter 4(It is from old book, for more information read chapter 8 in current book “Fundamentals of Human Physiology” by Silverthorn, Pearson education, and then on Animation Quizzes. Open the animations links and view the animations: 1) action potential propagation in an unmyelinated axon (the first animation) and 2) voltage gated channels and the action potential (the sixteenth animation). Take the quizzes under each animation.
Then go to http://faculty.washington.edu/chudler/ap.html
Read through the material. Observe the simulated action potential recording.
Procedure:
Insert the Ph.I.L.S. disk or access the online website.
Do Lab Activity: The Compound Action Potential (#12).
Conclusion:
Attach a screen shot (Ctrl & Prt Scr then paste) of the completed graph from your PhILS journal and Write a general narrative report (NOT scientific format) that discusses what can be learned from the exercise. Discuss a little and be sure to incorporate answers to the following questions in your narrative.
1. When a cell is at rest, what ions can pass through easily?
2. The words “spike” and “impulse” are used in place of what?
3. What is “threshold”?
4.Which ions move through the membrane causing depolarization?
5. Which ions move through the membrane causing repolarization?
6. What causes the sodium channels to open?

College for grading. Unless otherwise stated, answer in complete sentences, and be sure to use correct English, spelling and grammar. Sources must be cited in APA format. Your response should be four (4) double-spaced pages; refer to the &quote; Assignment Format & quote; page located on the Course Home page for specific format requirements.
Integrate by discussion the properties of life, basic chemical terminology, and molecules and compounds of a cell necessary for life. Include the basic anatomy and physiology of a cell and describe how cell respiration, photosynthesis, and cell reproduction occur in a succinct manner.
Include a brief discussion about Mendel’s Laws and an overview of DNA structure and function.
Conclude with a discussion of cancer and the mechanisms of gene control.

What is an infectious disease?

/in /by

Consider the following scenario:
Due to an increase in chronic diseases such as cardiovascular disease and cancer death in the United States as well as infectious diseases, the Center for Disease Control and Prevention (CDC), the Food & Drug Administration (FDA), and the National Cancer Institute (NCI) have formed a joint task force and has tasked you with developing an educational presentation on these topics to share with your community. Due to the public’s lack of knowledge on these topics, it is your job to create a presentation that is informative and educational regarding your chosen topic.
Research your topic using online sources such as the FDA, CDC, NIH, WHO and local sources for content on your topic for this presentation.
Choose ONE of the following chronic diseases/cancer and one of the infectious diseases:
Chronic Diseases/Cancer (select 1)
Coronary artery disease Hypertension Type 2 Diabetes Obstructive Pulmonary Disease (COPD) Obesity Alzheimer’s Disease Breast Cancer Lung cancer
Infectious Diseases (select 1)
Hepatitis A TB Influenza Staphylococcus HIV/AIDS
Create a 20- to 22-slide Microsoft® PowerPoint® presentation with appropriate images, if needed.
Include the following points for the chronic disease/cancer selected:
Provide a brief background on your chosen disease. Explain the disease. What are the risk factors, both modifiable and non-modifiable? Identify how this disease develops (is it sudden or progress through stages). What are the symptoms of the disease? Identify ways of preventing this disease. Include how a fitness or exercise program, if any, can help prevent this disease? How does exercise help prevent the disease? Identify the nutritional needs of the individual with this disease, as well as what diet should be implemented to meet the nutritional needs. Discuss both in terms of how diet can prevent the onset of the disease as well as the type of diet needed to treat the disease.
Explain how to treat this disease using conventional medicine and complementary and alternative medicine (CAM), otherwise known as holistic medicine. Discuss how conventional and CAM can be used to treat the disease. Which aspects of CAM are used in this particular chronic disease/cancer? Can CAM be used as a preventive measure? How? Make recommendations for where your audience might search for more information regarding this disease. Make sure these are credible sources (e.g. not Wikipedia). Explain the criteria for determining credible sources.
Include the following points for the infectious disease selected:
What is an infectious disease? Which infectious disease did you select? Define the disease you selected. Is the disease new or has it occurred in the past? Provide a brief history of this infectious disease. Does the disease present a significant problem for the human population globally, or is it localized? Describe the cause (name of the pathogen involved in the disease) and symptoms of the disease. Which populations are most susceptible to infection? How is the disease transmitted? Is there a vaccine or treatment available for the disease? How is it treated?
