Analysis Of Botulinum Toxin A And Interacting Proteins In Skeletal Muscle Cells: An Investigation Into The Mechanisms Of Botulinum Toxin A As A Treatment For Chronic Exertional Compartment Syndrome, Lauren Kee
Pence-Boyce STEM Student Scholarship
Background: Chronic exertional compartment syndrome (CECS) is a condition in which muscle tissue expands against the surrounding fascia during activity and is compressed along with the nerves and blood vessels within the muscle compartment, leading to abnormally high intracompartmental pressure (ICP) and debilitating pain. Treatment typically includes fasciotomy, which results in significant levels of CECS recurrence; however, botulinum toxin A (BoNT-A) injection has recently been seen to decrease both ICP and pain through an unknown mechanism with little to no recurrence.
Methods: In this study, cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), prostaglandin E2 receptor 4 (EP4), endothelial nitric oxide synthase (eNOS), …
Finding The Balance The Effects Of Α-Cyclodextrin, 2-Hydroxypropyl-Β-Cyclodextrin, And Cholesterol Bacteroides Vulgatus And Clostridium Bolteae, Bethany Weaver
Honors Program Projects
Atherosclerosis is a cardiovascular disease that is characterized by the hardening of arteries through the formation of cholesterol plaques. Cyclodextrins could potentially treat atherosclerosis by shrinking plaques. These cyclic oligosaccharides can make complexes with cholesterol but have also shown toxic side effects. This study looked for potential negative effects of cyclodextrins and cholesterol on gut bacteria. It was hypothesized that Bacteroides vulgatus will have decreased growth when grown in broth with cholesterol. In contrast, Clostridium bolteae will have decreased growth when grown in broth with cyclodextrins. Due to the fact that these bacteria are anaerobic, Clostridium bolteae and Bacteroides vulgatus, …
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 …
