The role of platelets in hemostasis. Introduction: Hemostasis is a process through which bleeding is stopped when there is an injury. There are fivestages of hemostasis: 1.Vascular Spasm 2.Formation of platelets plug 3. Coagulation of blood 4.Clot retraction 5.Clot dissolution Platelets play a vital role in the reaction that occurs after a blood vessel injury, during which platelets come near the vessel’s wall, carry out a release reaction, and then accumulate as a result of the materials released from platelets.

Summary Introduction

To review:

The role of platelets in hemostasis.

Introduction:

Hemostasis is a process through which bleeding is stopped when there is an injury. There are fivestages of hemostasis:

1.Vascular Spasm

2.Formation of platelets plug

3. Coagulation of blood

4.Clot retraction

5.Clot dissolution

Platelets play a vital role in the reaction that occurs after a blood vessel injury, during which platelets come near the vessel’s wall, carry out a release reaction, and then accumulate as a result of the materials released from platelets.

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.
