Mediation Of The Uncoupled Enos Pathway Following Oxidative Stress Using Tetrahydrobiopterin And Nitric Oxide Donor Drugs To Restore Tetrahydrobiopterin Concentration, Brianna Munnich

Scholar Week 2016 - present

Presentation Location: Warming House, Olivet Nazarene University

Abstract

The eNOS pathway, found in the endothelium of blood vessels, is a key regulator of nitric oxide levels in the circulatory system. The pathway is controlled through several positive and negative feedback loops [2]. The cofactor tetrahydrobiopterin (BH4) is a major control point in this pathway and under conditions of stress can be reduced into the dihydrobiopterin (BH2) [2,6,7,8,9]. When the reduced form is predominant, the pathway produces reactive oxygen species (ROS) rather than nitric oxide, causing stress and damage to the vessels [6,7,8,9]. In this study, different treatments were studied …

Measuring The Decrement Times Of Volatile Anesthetics In Drosophila Melanogaster Using Gas Chromatography-Mass Spectrometry, Jason Tolley

Scholar Week 2016 - present

Presentation Location: Warming House, Olivet Nazarene University

Abstract

Background

Model organisms are widely used in research, especially in the context of complex situations. One model organism that has been widely used is the common fruit fly, Drosophila melanogaster (D. mel). D. mel are most commonly used in the context of genetics, but they have also been widely used in research focusing on general anesthetics. One value that has not been measured in D. mel, however, as it relates to general anesthetics, is the decrement times. This is what was the present research set out to determine. …
