Survey of rhizosphere associated entomopathogenic fungi on small fruits and Christmas trees in the Willamette Valley, OR

Creator:: Fisher, Joanna J.
Abstract:: The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are commercially available as microbial control agents for the black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), the key root-feeding insect pest in Pacific Northwest small fruits and ornamentals. Understanding habitat selection is critical to improve the efficacy, persistence and cost of...

Pheromone mating disruption of filbertworm moth (Cydia latiferreana)in commercial hazelnut orchards

Creator:: Hedstrom, Christopher
Abstract:: BACKGROUND: Oregon produces 99% of the hazelnuts grown in the United States. The key pest threatening commercial hazelnut orchards in Oregon is Cydia latiferreana (Tortricidae), filbertworm moth (FBW). Currently, most growers control FBW with one to two applications of esfenvalerate (Asana XL), a broad spectrum pyrethroid. Pheromone mating disruption is...

Response of reef fish assemblages to overgrowth of the hydrocoral Millepora complanata by the crustose alga Ramicrusta sp.

Creator:: Adams, AnnaRose
Abstract:: Natural disturbances and human activities can alter the benthic composition of coral reefs and other marine ecosystems. Reef fishes that associate with particular structures on the sea floor, such as coral heads, may be vulnerable to perturbations of those habitats. The spread of a newly discovered crustose alga (Ramicrusta sp.)...

Quantification of Cytokine Production Following Exposure to 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) to Determine Potential Role in Suppression of the Immune Response in a Graft versus Host (GvH) Model

Creator:: Magaña, Laura Cristal
Abstract:: 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a potent immunosuppressant and a prototypic ligand for the aryl hydrocarbon receptor (AhR). In a graft versus host (GvH) response, treatment with TCDD suppresses a cytotoxic T-lymphocyte (CTL) response by Day 10, concurrent with a T-regulatory (Treg) like phenotype in the donor CD4+ T-cells, observed on Day...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

Inhibition of α-Amylase and α-Glucosidase by Bioflavonoids

Creator:: Griffith, Anneke M. (Tucker)
Abstract:: Various flavonoid-rich plant extracts have shown efficacy in the treatment of diabetes. Although it is often assumed that dietary flavonoids exert biological antioxidant effects, it is possible that the observed effects work in carbohydrate metabolism. In this study we evaluated the effect of catechins and catechin containing extracts on α-amylase...

Automated annotation of Caenorhabditis mitochondrial genomes and phylogenetic analysis

Creator:: Campbell, Jessica L.
Abstract:: Motivation Relatively little is known about the evolution of mitochondrial genomes between Caenorhabditis species despite decades of research. Both the worldwide search for new nematode species and the effort to increase sequencing speeds require automated tools to quickly characterize and categorize large amounts of data. Results We developed an automated...

Discovery and Isolation of Bioactive Natural Products from Actinomycete Bacteria with an Examination ofInfectious Disease Drug Development and Application : A Comparison of the Developing and Developed Worlds

Creator:: Petrossian, Gregory
Abstract:: New antibiotic compounds with novel mechanisms of action have become essential in response to the recent paradigm of increasingly resistant strains of bacteria. Secondary metabolites (natural products) from bacteria such as Actinobacteria serve as lead compounds for the development of pharmaceutical drugs widely used to fight bacterial, viral and fungal...

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...

Probing Circadian Clock-Steroid Receptor Interactions in GnRH Neurons

Creator:: Grimwood, Victoria J.
Abstract:: Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...

The Release of Nickel from Stainless Steel into Cooked Foods

Creator:: Kamerud, Kristin L.
Abstract:: Toxicological studies show that oral doses of nickel can cause allergic contact dermatitis, and routes of exposure, such as nickel leached from stainless steel cookware are not well characterized. In this study, four variables: grade of stainless steel, cook time, stainless steel seasoning or cooking cycles, and commercial tomato sauces,...

Discovery and Characterization of New Cyanobacterial Natural Products from Moorea sp

Creator:: Cowley, Elise Shylo
Abstract:: Natural products (secondary metabolites) are small organic molecules derived from plants, microbes, and marine organisms that have served as a diverse source of useful compounds pharmaceuticals. New biologically active natural products are critical as anti-infective and cancer drug leads. Cyanobacteria, or blue-green algae, produce diverse cytotoxic metabolites that represent potential...

De novo Discovery of Novel Long Noncoding RNAs in the North American Beaver

Creator:: Kashyap, Amita
Abstract:: Long noncoding RNAs (lncRNAs) are RNA molecules that are at least 200 nucleotides long and do not encode proteins. lncRNAs have roles in gene regulation, chromatin epigenetics, and molecular scaffolding. In light of mounting evidence implicating species-specific noncoding RNAs and gene regulatory mechanisms in species adaptations, it is reasonable to...

Functional consequences of microRNA regulation by polycyclic aromatic hydrocarbons in 3D human bronchial epithelial cells

Creator:: Mans, Michael-Andres D.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a class of contaminants ubiquitous in the environment and result from the incomplete combustion of fossil fuels. Many PAHs have been identified as procarcinogenic, and are metabolized to form DNA adducts; however, other mechanisms also may contribute to toxicity and help explain differences in toxicity...

Vegetative effects of RNAi-suppression of the poplar homolog of LEAFY in the field

Creator:: Jacobson, Jeremy
Abstract:: Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...

Use of Platelet Rich Plasma for the Treatment of Subclinical Endometritis in Beef Heifers

Creator:: Puttman, Elizabeth A.
Abstract:: Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...
