How the preparation and analysis of a pedigree help to explain the dilemma faced by Thomas and his family. Introduction: Huntington’s disease affects the brain, causes changes in the movement, mood and thinking skills. It is a progressive disease and inherited by dominant alleles. Huntington’s disease cannot be cured and the changes of the brain cannot be stopped or slowed down. Thomas’s brother was diagnosed with dementia, muscular rigidity, seizures and at the age of 49, it is confirmed that he is suffered from Huntington’s disease. Thomas and family are educated about this threatening disease when they approach the genetic counselor.

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.
