A Multi-Tiered Approach Using Daphnia magna to Assess Chlorpyrifos Risk to Aquatic Receptors

Creator:: Maggio, Stephanie A.
Abstract:: Chlorpyrifos (CPF) is a widely used broad-spectrum organophosphate insecticide. Following exposures, CPF and its more toxic oxon metabolite (CPFO) elicit neurotoxic effects by inhibiting the activity of the acetylcholinesterase enzyme (AChE), resulting in altered fitness and death at high doses. Following exposure, organisms bioactivate CPF to CPFO through the Cytochrome...

Protein methylation at sites of blood vessel injury

Creator:: Weber, Darin J.
Abstract:: Blood vessel injury was found to release intracellular pools of protein D-aspartyl/L-isoaspartyl carboxyl methyltransferase (PIMT) into the extracellular milieu, where it became trapped. Trapped PIMT was able to utilize radiolabeled S-adenosyl-L-methionine (AdoMet) introduced into the circulation to methylate blood vessel proteins containing altered aspartyl residues specifically at the site of...

Molecular and genetic assessment of selected antiporters and methyl-accepting chemotaxis proteins in Vibrio cholerae

Creator:: Quinn, Matthew J.
Abstract:: The pathogen Vibrio cholerae uses cations as a primary currency of virulence and environmental persistence, using gradients of those cations to move, acquire nutrients, and control virulence gene expression. An understanding of the overlapping roles of bioenergetics and chemotaxis in the virulence and environmental survival of V. cholerae issues from...

In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

Creator:: Blizzard, Robert J.
Abstract:: The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...

Short-term relationship of timber management and Pacific giant salamander populations, and the response of larval stream amphibian to predators under differing sediment levels

Creator:: Leuthold, Niels C.
Abstract:: In the Pacific Northwest, multiple studies have found negative effects of timber harvest on stream amphibians, but the results have been highly variable and region-specific. In this collection of studies, I examined the short term effect of timber harvest using a field study, and used lab work to examine a...

Computational Investigations of Transition Metal Catalyses and Amorphous Metal Oxides : Accelerating Scientific Discovery Through Automation

Creator:: Mustard, Thomas J. L.
Abstract:: Automation of computational chemistry, while only an engineering feat, has the potential to accelerating computational research be removing all by the science. The work in this thesis mainly discusses fundamental understanding of complex chemical systems. What is not obvious are the numerous tasks necessary for this fundamental understanding. Under the...

Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:: Lee, Jae-Hyuk
Abstract:: This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

“We Don’t Stop ‘til We Get There”: Reframing the Hip Hop Ill-literacies of Latinx Youth

Creator:: Cole, Matthew C.
Abstract:: The experiences of Latinx youth are well-studied in U.S. schools, yet, few studies have focused on their experiences in Community Based Educational Spaces (CBES). CBES continue to be on the periphery of Education research despite the potential affordances of youth-led work in such out-of-school spaces (Baldridge, 2020). At the same...
