Hepatitis B and liver cancer among Hmong : knowledge, perceptions of risk, and barriers to hepatitis B screening and vaccination

Creator:: Kue, Jennifer
Abstract:: Chronic hepatitis B disproportionately affects Asian Americans. Although Asians make up only 4.2% of the total United States (U.S.) population, they account for more than half of those infected with hepatitis B. If left untreated, chronic hepatitis B could lead to cirrhosis, liver damage, and liver cancer. Studies show that...

Topometric Analysis for High-throughput Phenotyping of Seed Shattering in Perennial Ryegrass (Lolium perenne L.)

Creator:: Tubbs, Travis B.
Abstract:: Seed shattering is a constraint to improvement of seed yield in Lolium perenne L. and as a result, seed retention is an essential trait for this valuable crop. Field studies were conducted near Corvallis, OR in two years (2017-2018 and 2018-2019) to identify genetic variation for seed retention and to...

Advanced Approaches in Hazard Assessment of Polycyclic Aromatic Hydrocarbons Using Zebrafish

Creator:: Wilson, Lindsay B.
Abstract:: The field of toxicology is challenged with a vast number of environmental chemicals and mixtures to which humans and ecosystems are exposed with limited toxicity data available. Chemical hazard assessment traditionally utilizes mammalian models and can be both cost- and time-limiting and may pose ethical concerns. To rapidly tackle this...

Magma dynamics and evolution in continental arcs : insights from the Central Andes

Creator:: Grocke, Stephanie B.
Abstract:: Constraining the magma evolution and dynamics that lead to the eruption of large volume continental arc systems is fundamental to our understanding of continental crust formation.

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

DNA mismatch repair-dependent responses to the food-borne carcinogen 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) in the mouse

Creator:: Smith-Roe, Stephanie L.
Abstract:: The DNA mismatch repair (MMR) pathway maintains genomic stability and reduces cancer risk (colorectal and other internal cancers) by correcting polymerase errors and activating cell cycle checkpoints and apoptosis in response to DNA damage. Few studies have examined the influence of commonly encountered environmental mutagens/carcinogens on the etiology of MMR-deficient...

Effects of DNA mismatch repair inhibition in Arabidopsis thaliana

Creator:: Wilcox, Buck W. L.
Abstract:: Genomic instability underlies diseases of unregulated cell growth that result in cancers and developmental abnormalities in humans. Similar genome destabilizing mechanisms are used to create genetic variety in crops for use in breeding and trait development. Errors that occur during DNA replication may cause mutations if they are not corrected...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

Dietary soy and green tea in the prevention of prostate cancer

Creator:: Hsu, Anna
Abstract:: Prostate cancer risk is significantly lower in Asian countries compared to the US, which has prompted interest in the chemo-preventative action of dietary components such as soy and green tea commonly found in Asian diets, such as soy and green tea. Studies have suggested that soy isoflavones and green tea...

Evaluation of vitamin B-6 status of Saudi adult males in the Riyadh region - Saudi Arabia

Creator:: Al-Assaf, Abdullah
Abstract:: The aim of this study was to investigate the vitamin B-6 status of Saudi adult males and compare the status between rural and urban subjects. Fifty-one adult male subjects were recruited from urban (n=31) and rural (n=20) populations of Riyadh. These subjects were reclassified to cigarette smokers (n=19), water pipe...

Mass Spectrometry-based Analysis of Superwarfarins and their Metabolites and the Investigation of Novel Treatments for Poisoned Victims

Creator:: Nosal, Daniel Grzegorz
Abstract:: Superwarfarins are anticoagulant rodenticides that are 100 times more potent and 15 times more persistent than warfarin. They have been used since the 1980s and cause over 10,000 cases of accidental and intentional poisonings per year. Apart from inducing uncontrollable bleeding, by inhibiting the vitamin K cycle, superwarfarins can disrupt...

Abstract:: The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...

Abstract:: The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...
