Resolving Acne With Optimized Adapalene Microspongeal Gel, In Vivo And Clinical Evaluations, Rania Yehia, Dalia Attia, M. M. Elmazar Jan 2024

Resolving Acne With Optimized Adapalene Microspongeal Gel, In Vivo And Clinical Evaluations, Rania Yehia, Dalia Attia, M. M. Elmazar

Pharmacy

In our pursuit of enhancing acne treatment while minimizing side effects, we developed tailored Adapalene microsponges (MS) optimized using a Box–Behnken design 33. The independent variables, Eudragit RS100 percentage in the polymer mixture, organic phase volume, and drug to polymer percentage, were explored. The optimized formulation exhibited remarkable characteristics, with a 98.3% ± 1.6 production yield, 97.3% ± 1.64 entrapment efficiency, and a particle size of 31.8 ± 1.1 μm. Notably, it achieved a 24 h cumulative drug release of 75.1% ± 1.4. To delve deeper into its efficacy, we evaluated the optimized microspongeal-gel in vitro, in vivo, and clinically. …


The Effects Of Alcohol On Crash Avoidance Reaction Time In A Driving Simulator Task In Humans, Aishwarya Vasudevan Jan 2024

The Effects Of Alcohol On Crash Avoidance Reaction Time In A Driving Simulator Task In Humans, Aishwarya Vasudevan

Wayne State University Theses

AIM 1: Alcohol-impaired driving continues to be a significant cause of car crash injuries and deaths. The blood alcohol concentration (BAC) cut-off level for drunk driving is 0.08% in Michigan, and is estimated that lowering this cut-off to 0.05%would save 500–800 lives every year in the US alone. We used a portable virtual reality (VR)-based driving simulator to demonstrate the effects of alcohol at BAC concentrations 0.02-0.08%, grouped into 0.01% increments, on driving performance, specifically Crash Avoidance Reaction Time (CART), i.e., the time (in msec) required to initiate a steering avoidance response. We found that BAC concentrations as low as …


The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson Jan 2024

The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson

Honors College Theses

The purpose of this research is to improve understanding of the neurodevelopmental effects of embryonic exposure to elevated inflammation and oxidative stress induced by the antipyretic drug acetaminophen (APAP). Our study was the first to examine the interactive effects of APAP and inflammation in zebrafish embryos and how the treatments affect brain development and larval behavior. Experimental groups of zebrafish larvae were exposed to lipopolysaccharide (LPS) to induce inflammation, APAP, or LPS + APAP and larval behavior was analyzed using Ethovision automated behavioral tracking software. We also measured changes in whole-brain Glycogen Synthase Kinase 3 Beta (GSK3B) and GSK3B phosphorylation, …
