Measuring The Decrement Times Of Volatile Anesthetics In Drosophila Melanogaster Using Gas Chromatography-Mass Spectrometry, Jason Tolley Apr 2021

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. …


Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger Mar 2021

Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger

Scholars Week

Life history morph, sex, and body condition are traits that may influence stress within salamander populations because of differences in physiology and environmental conditions. Given widespread declines and the effects chronic stress can have on amphibian health, it is important to understand within-population drivers of stress and how population level variation may influence population viability. Thus, the objective of our study was to assess how corticosterone varies within the Arizona tiger salamander (Ambystoma mavortium nebulosum) population at the Mexican Cut Nature Preserve. We used a non-invasive skin swabbing method to collect baseline and elevated corticosterone from paedomorph (aquatic …

Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.

The purpose of this study is to …


Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona Mar 2018

Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona

Smoothened receptor (SMO) is a protein that in humans, is encoded by the SMO gene. A systemic mutation in its binding pocket helps predict the sensitivity of mutant proteins to different drugs. Known as a GPCR-like receptor, it is a component of the hedgehog signaling pathway; a pathway involved in body patterning and the regulation of adult stem cells. An uncontrolled or inappropriate activation of the Hedgehog pathway drives tumor progression in cancers and a number of birth defects. To achieve these goals, the molecular modeling software MOE was used to build small molecules and drug molecules like Vismodegib and …
