Elucidating the Mechanism of Action of Unnatural Amino Acid Containing Antimicrobial Peptides in Membrane Environments
Clark, Tiffany D. (East Carolina University, 2012)Organism resistance continues to develop to the currently available antimicrobial compounds necessitating the development of innovative new therapeutic compounds with different specificities and mechanisms of action that ... -
Elucidating the Mechanisms of Transthyretin Aggregation in Transthyretin Amyloidosis
Dasari, Anvesh K. R. (East Carolina University, 2018-07-24)Accumulation of insoluble aggregates (amyloids) is a characteristic feature of many neurodegenerative diseases including Alzheimer's disease and Parkinson's disease. Aggregation and deposition of Transthyretin (TTR) protein ... -
EXPLORATION INTO THE SCOPE AND MECHANISM OF THE PLATINUM-CATALYZED ACYLATION OF 2-(ARYLOXY)PYRIDINES
Guthrie, Jacob D (East Carolina University, 2019-07-11)Transition metal catalysts have played a key role in direct C-H bond functionalization. However, one main drawback of these reactions is that oxidants and additives are often required to regenerate the active catalyst, ... -
EXPLORING STUDENT EXPERIENCES ACROSS A LINKED SEQUENCE COURSE-BASED UNDERGRADUATE RESEARCH EXPERIENCE
Whiting, Brandon (East Carolina University, 2020-11-23)This study reports the effect a linked Course-based Undergraduate Research Experience (CURE) has on a students' understanding of research and the associated experiences they encountered. CUREs offer an alternative path to ... -
Extraction of Salvia miltiorrhiza Using Subcritical Water
Biller, Jessica, J (2014)Salvia miltiorrhiza, also known as Danshen, is an herb commonly used in Chinese medicine to treat cardiovascular and other diseases. As it has recently gained more recognition, this herb is currently being investigated for ... -
Fluorescent Derivatives of Prostamides: Tools for Studying Anti-Cancer Activity
Stanley, Jordan Lynne (East Carolina University, 2018-07-23)The endocannabinoid arachidonoyl ethanolamide (AEA) and prostaglandins derived from it selectively induce apoptosis in tumorigenic cell lines due to overexpression of COX-2. It is likely that a novel J-series prostamide, ... -
