Antioxidant enzyme response in rainbow trout (Oncorhynchus mykiss) after subchronic exposure to an environmentally-relevant polycyclic aromatic hydrocarbon mixture

Creator:: Norby, Tyler S.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage. The aim of this study...

Chlordecone (CD), a mixed steroid X receptor (SXR) and estrogen receptor alpha(ERα) agonist, altered hepatic cholesterol (CH) homeostasis and lipoprotein metabolism

Creator:: Lee, Junga
Abstract:: Overtly non-toxic doses of organochlorine (OC) insecticides perturb lipid homeostasis in mice and rats. To increase understanding of how chlordecone (CD), an OC insecticide, modulates cholesterol (CH) homeostasis, we determined the effect of CD pretreatment on the tissue and hepatic subcellular distribution of exogenous [¹⁴C]CH. Corn oil alone or CD...

The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Toxic politics at 64N, 171W : addressing military contaminants on St. Lawrence Island, Alaska

Creator:: Henifin, Kai A.
Abstract:: St. Lawrence Island, Alaska is home to two Formerly Used Defense Sites (FUDS) under remediation by the U.S. Army Corps of Engineers since 1985. After more than two decades the local residents continue to be concerned about inadequate site characterization and cleanup. During the summer of 2005, I collected ethnographic...

Geneticist L.C. Dunn : politics, activism, and community

Creator:: Gormley, Melinda (Melinda Brooke)
Abstract:: L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Kinematic and cyclostationary parameter estimation for co-channel emitter location applications

Creator:: Ohm, David R.
Abstract:: The problem of locating a signal source, or an emitter, has many civilian and military applications, such as communication regulations enforcement, military reconnaissance, and search-and-rescue operations. Many of the most widely used emitter location methods rely on the accurate and robust estimation of the differential time delay, or time-difference-of-arrival (TDOA),...
