Feasibility of Corbicula flumina as abiomarker for environmental pollutants in the Willamette River

Creator:: Lauderbach, Douglas
Abstract:: This report examines the feasibility of using the bivalve Corbicula flumina as a biomarker for environmental contaminants in the Willamette River. Compounds such as DDT, dioxins, furans, and PCBs persist in the environment, pose health related concerns, and due to their lipophilic nature accumulate in biological organisms. The success of...

Biosynthetic Studies of the α-Amylase Inhibitor Trestatin in Streptomyces dimorphogenes

Creator:: Demessie, Ananiya A.
Abstract:: The prevalence of obesity and diabetes in the United States and globally has been rising in the last few decades and it continues to climb. One of the causes for this increase is the over consumption of sugars and/or carbohydrates. Among medications available to treat obesity and diabetes are the...

DNA Mismatch Repair-Dependent Suppression of Genotoxicity of Benzo[a]pyrene Diol Epoxide

Creator:: Kernan, Casey P.
Abstract:: DNA mismatch repair (MMR) plays an important role in preserving genomic stability and reducing cancer risk. Environmental exposures to polycyclic aromatic hydrocarbons (PAHs) are believed to contribute significantly to carcinogenesis. PAHs are found in food, air, water and soil and upon bioactivation can form diol epoxides which are electrophilic in...

Genetic variation of Renibacterium salmoninarum genes in infected salmonids

Creator:: Burnett, Jeffrey R.
Abstract:: Renibacterium salmoninarum is the causative agent of bacterial kidney disease in both wild and farmed salmonid species worldwide. The genome of this pathogen has significant synteny to the ubiquitous, soil-dwelling Arthrobacter spp. though it is 1.9 Mb smaller, suggesting that reductive evolution has occurred. Recently, our group finished sequencing and...

Trace element concentration in tree-rings biomonitoring centuries of environmental change

Creator:: Padilla, Kimberly L. and Anderson, Kim A.
Abstract:: Inductively coupled plasma mass spectrometry (ICP-MS) was used to examine trace element concentration in treerings over three and half centuries to assess macro-trends of environmental change. Tree-rings of a 350+ year old mammoth ponderosa pine (Pinus ponderosa) were analyzed for element concentration and evaluated versus local and global historical events....

Reduced toxicity of benzethonium chloride to Escherichia coli through adsorption onto titanium dioxide nanoparticles

Creator:: Waldron, Kerri Raven
Abstract:: Antimicrobial agents are being increasingly used in consumer soaps and detergents, despite a lack of data demonstrating their efficacy in such products. This study investigated the nature of the interaction between different crystalline structures of titanium dioxide nanoparticles and BTC, and explore which structure, if any, could be best used...

Potential of eradicating noxious weed seeds from the soil with heat and carabid seed predators

Creator:: Marshall, Nicole S.
Abstract:: The goal of this project was to develop and test non-herbicidal techniques that remove nonnative plant or weed seeds from the top 2 inches of the soil. The Nature Conservancy (TNC) is currently restoring prairies in the Willamette Valley. Some areas of the Pacific Northwest have already seen loss of...

Biogeochemistry of inorganic P, Mn, and Fe in seasonally reduced soils of the Willamette Valley, Oregon

Creator:: King, Rex
Abstract:: Saturated soils undergo reduced conditions as microorganisms consume oxygen and require other terminal electron accepting processes for the mineralization of soil organic carbon. Currently, the soil redox potential has not been considered as important when sampling these soils for Fe, Mn, and P04. Since Fe- and Mn-oxides are electron sinks...
