Explanation Nitroglycerin is the preliminary preferred treatment for angina pectoris and chest pain. The main mechanism behind considering nitroglycerin is that it relaxes the vascular smooth muscle. It dilates both arterial and venous beds. Vasoconstriction and vasodilatation are often coupled to change in cardiac output. Vasoconstriction is induced by the peptide, and vasodilatation is induced by the nitric oxide...

Chapter 42.4, Problem 3CC

Summary Introduction

To explain: The reason behind why nitroglycerin is preferred to relieve chest pain and used to treat heart disease patients.

Concept introduction:

Nitroglycerin is used as a vasodilator that opens blood vessels to improve blood flow. Angina results when there is imbalance between the oxygen supply and oxygen demand without a proportional increase in supply. The process of narrowing of arterioles is known as vasoconstriction. The process of relaxation of arterioles is known as vasodilatation.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
