Engineering A Mutation In The Heparin Binding Pocket Of The Human Fibroblast Growth Factor, Roshni Patel
Engineering A Mutation In The Heparin Binding Pocket Of The Human Fibroblast Growth Factor, Roshni Patel
Chemistry & Biochemistry Undergraduate Honors Theses
Fibroblast growth factors (FGFs) are family of proteins that belong to a group of growth factors that are found in mammals and play an important role in angiogenesis, differentiation, organogenesis, and tissue repair. In summary, their main functionality is involved in cell division and proliferation. Because FGFs plays such a vital role in cell proliferation, they are mainly involved in the process of wound healing and injuries. FGF binds to its ligand, heparin—a heavily sulfated glycosaminoglycan. The binding of heparin to FGF occurs through electrostatic interactions, specifically between the negatively charged sulfate groups on heparin and positively charged residues such …
Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir
Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir
Animal Science Undergraduate Honors Theses
One societal trend that has been gaining much traction and popularity since the 21st century began is “organic” and/or “natural” food products. In 1999, the global market accounted for $15.2 billion dollars worth of organic food and drink, compared to the market in 2014 where we consumed $80 billion dollars worth (Willer et. al, 2016). With “natural” production of food animals however, “natural” parasite transmission may be a consequence. To that end, this experiment examines the prevalence of helminths in 110 “natural” laying hens from three regional farms and the efficacies of fenbendazole, piperazine, and levamisole on what should …

Exploring The Mechanisms Of Action Of Antifungal Peptides Using Saccharomyces Cerevisiae., Michelle L. Mason
Biological Sciences Undergraduate Honors Theses
Candida albicans is a normal inhabitant of the skin and mucosal membranes of humans, however, in individuals with depressed immune systems or disrupted cutaneous flora, Candida can overgrow and cause serious infection. Candida infection is the fourth leading cause of nosocomial infection in the United States. These infections are often associated with longer hospital stays and higher mortality. Current drug therapies for this infection are largely ineffective due to the increased drug resistance of Candida species, and for some therapeutics, high levels of drug toxicity to humans. Histatin 5 is a naturally occurring salivary peptide that has strong antifungal properties. …
The Effects Of Smoking On The Calcification Of The Aortic Valve, Brittany Pendergraft
The Effects Of Smoking On The Calcification Of The Aortic Valve, Brittany Pendergraft
Biological Sciences Undergraduate Honors Theses
Calcific Aortic Valve Disease is responsible for approximately 28,000 deaths annually and the complete mechanism is not completely understood. The disease is known to be effected by an inflammatory response, osteogenic response and an oxidative stress response that leads to thickening and mineralization of the aortic valve. Originally, this disease was thought to be brought on by age and deterioration of the valve but these rapid stress responses when the valve is disrupted by biochemical and mechanical stress has led to its classification as an active disease. Smoking has been shown to have many of the same effects experienced by …
Synthesis Of Medicinally Relevant Thiazolyl Aryl Ketones Under Mild Conditions, Danielle M. Gardner
Synthesis Of Medicinally Relevant Thiazolyl Aryl Ketones Under Mild Conditions, Danielle M. Gardner
Health, Human Performance and Recreation Undergraduate Honors Theses
Purpose: The growing amount of clinical resistance observed in current antifungal drugs and in anti-HIV pharmaceuticals is a concern in the medical community. The purpose of this study is to develop a mild synthetic process for biomedically relevant thiazolyl aryl ketones that can be used to develop antifungal and anti-HIV drugs. We hypothesized that the proposed synthetic technique would be more efficient, produce fewer unwanted byproducts, and be more tolerant of functional groups than existing methods.
Methods: Prior to each of the ketone reactions, the necessary salt was synthesized by mixing thiazole and 9-bromofluorene neat in a reaction tube heated …
Developing A Presumptive Test For Select Synthetic Cannabinoids, Carrie Snyder
Developing A Presumptive Test For Select Synthetic Cannabinoids, Carrie Snyder
Graduate Theses and Dissertations
Synthetic cannabinoids (SC's) began to gain popularity around the world in 2009. Since then, many of the compounds have been outlawed and methods developed to detect them and their metabolites using mass spectrometry. Our work investigated the possibility of developing a colorimetric presumptive test. The SC JWH-019 was synthesized and its ketone targeted as a possible reaction site. Many SC's contain ketones and thus a reaction at this site would be applicable to many of the compounds. Since JWH-019 is costly and time consuming to synthesize, much of the experimental work was done using benzophenone (BP). BP contains a diaryl …
