Combining Bioinformatics And Chemical Biological Approaches To The Study Of Signaling Pathways In Parasitic Nematodes, William R. De Martini
Combining Bioinformatics And Chemical Biological Approaches To The Study Of Signaling Pathways In Parasitic Nematodes, William R. De Martini
Theses, Dissertations and Culminating Projects
Lymphatic filariasis (elephantitis) is a disfiguring disease caused by thread-like nematodes. This disease affects the lives of over 120 million people and over one billion people are at risk for infection in endemic regions. Drugs used to treat this disease suffer from toxicity and emerging resistance and new therapies need to be identified. Our laboratory has been studying the filarial parasite, Brugia malayi (B. malayi), one of the causative agents of this disease. The laboratory is focused on the study of critical protein kinase signaling pathways, necessary for parasite protective anti-oxidative responses, as potential therapeutic targets. We have previously determined, …
The Applications Of Graphene And Its Derivatives For Heavy Metal Removal, Clemonne John Madarang
The Applications Of Graphene And Its Derivatives For Heavy Metal Removal, Clemonne John Madarang
Theses, Dissertations and Culminating Projects
Heavy metal pollution is very prevalent in our environment. The entire removal of heavy metal and organic contaminants in natural water resources will not only affect the environment itself, but also can block the toxic contaminant transfers in food chains. Currently, there are many studies being done to remove these heavy metal ions from our water, such as reduction reactions, chemical precipitation, reverse osmosis and electrolytic recovery. One of the promising techniques is adsorption. The focus of this research is using graphene and its derivatives, such as silylated graphene oxide (GO), to adsorb heavy metals, specifically, lead. This research describes …
Investigation Of Charge Recombination In Escherichia Coli Photolyase And Vibrio Cholera Cryptochrome Dash, Agnieszka Zieba
Investigation Of Charge Recombination In Escherichia Coli Photolyase And Vibrio Cholera Cryptochrome Dash, Agnieszka Zieba

Proton-coupled electron-transfer (PCET) is a mechanism of great importance in protein electron transfer and enzyme catalysis, and the involvement of aromatic amino acids in this process is of much interest. The DNA repair enzyme photolyase provides a natural system that allows for the study of PCET using a neutral radical tryptophan (Trp‘). In Escherichia coli photolyase, photoreduction of the flavin adenine dinucleotide (FAD) cofactor in its neutral radical semiquinone form (FADH') results in the formation of FADH and Trp . Charge recombination between these two intermediates requires O A/T # the uptake of a proton by ~ Trp . The …
Preparation And Crystal Structures Of Chiral And Non-Chiral Mixed Ligand Copper Complexes Containing N-Methyl Imidazole And Various N-Phthaloylalanines, Hiral Patel
Theses, Dissertations and Culminating Projects
A quasiracemate is the cocrystallization of two similarly shaped but chemically distinct molecules of opposite handedness. There has been extensive work done in the field of organic quasiracemates by Dr. Kraig A. Wheeler. Limited work has been done in inorganic quasiracemates. The goal of this study was to prepare various metal based enantiomers, racemates, and quasiracemates using A-phthaloylalanines, and TV-methylimidazole as ligands bound to copper arranged in a centrosymmetric pattern. In this study, we developed a method to prepare A-phthaloylalanines and its copper complexes. Three complexes have yielded crystal structures: a racemate, bis(7V-methylimidazole) bis(D,L-3-chloro-7V-phthaloylalanato)copper(II); a quasiracemate, bis(A-methyhmidazole)(L-3-chloro-iV-phthaloylalanato)(D-3-methyl-7V-phthaloylalanato) copper(II); and an …
