Neuronal Degeneration And Short-Term Memory Impairment After Tbi, Obiamaraije Igwe Nov 2017

Neuronal Degeneration And Short-Term Memory Impairment After Tbi, Obiamaraije Igwe

Posters-at-the-Capitol

Traumatic brain injury (TBI) was associated with impaired short-term memory with causes of vehicle accidents and falls. Protein plaques containing fibrinogen (Fg), are associated with memory loss. After TBI, Fg in blood was higher than normal (>~2 mg/ml), which resulted in increased Fg in extravascular space. Therefore, Fg bonded to its endothelial receptor intercellular adhesion molecule-1 (ICAM-1). Fg then interacted with cellular prion protein (PrPC), which had a strong effect on the loss of memory and cognition. Mechanisms of Fg and PrPC complex formation and its functional implication are not known. This present study tested the level of Fg-PrPC …

Using Fluorescence Microscopy To Identify A Potential New Treatment For Heart Failure, Ryan D. Himes Apr 2017

Using Fluorescence Microscopy To Identify A Potential New Treatment For Heart Failure, Ryan D. Himes

Scholar Week 2016 - present

Cardiac glycosides have been used to treat heart failure for centuries, but they have a narrow therapeutic window, as they inhibit their target receptor nearly irreversibly. Overdoses can lead to arrhythmias. Phospholemman is a natural inhibitor of the same target as cardiac glycosides. It is possible that mutating phospholemman could achieve the same therapeutic benefit, while allowing cells to reverse the inhibition and thereby avoid an arrhythmia. I used fluorescence microscopy to screen candidate phospholemman mutants and identify one that binds more avidly to its target than the naturally occurring phospholemman. This mutant, L30A, caused similar effects as cardiac glycosides …


Antiproliferative Effects Of Hibernating American Bullfrog (Rana Catesbeiana) Blood Plasma On Thp-1 Cells, Sean Robbins Apr 2017

Antiproliferative Effects Of Hibernating American Bullfrog (Rana Catesbeiana) Blood Plasma On Thp-1 Cells, Sean Robbins

Annual Graduate Student Symposium

Hibernation is an incredible adaptation that allows an organism to go dormant during the winter, when food is scarce. Much is unknown physiologically about hibernation, and most current research comes from mammalian models. During hibernation, the cells of mammals are impeded from going through mitosis. 13-lined ground squirrels (Ictidomys tridecemlineatus) and woodchucks (Marmota monax) have a protein, alpha-2-macroglobulin, in their blood plasma, which has significant antiproliferative effects on spleen cells. The goal of my study was to determine if an exothermic organism, the American Bullfrog (Rana catesbeiana), also actively suppresses mitosis while hibernating and if so, determine if it is …
