Why ELISA test is used to screen human serum for the AIDS virus, while Western blot techniques are used only as a confirmation test. Introduction: Acquired immunodeficiency syndrome (AIDS) is a disease of the immune system caused by the human immunodeficiency virus (HIV). Human immunodeficiency virus is a sexually transmitted infection, and it can be spread from mother to child during breastfeeding, childbirth, infected blood transfusion, and sexual intercourse.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.

Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
