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...

Native bees, honeybees and pollination in Oregon cranberries

Creator:: McKenney, Melissa A.
Abstract:: Farmers rely almost exclusively on the imported European honeybee (Apis mellifera L.) for fruit and vegetable crop pollination services. The recent decline in honeybee health has underscored the danger of relying on a single species to provide vital services. Increasing pollinator biodiversity with native bees may provide biological insurance against...

Investigation of microbial extracts as a source of neurological agents

Creator:: Malmo, Jay M.
Abstract:: This study tested natural products from cyanobacteria from the Red Sea in Egypt and marine tunicates from the Algoa Bay in South Africa. Products from marine organisms have been used as lead compounds for the synthesis of new drugs because of their biological activity mechanism. Specifically, these products may contain...

Use of Artemisinin to Treat Mycoplasma haemolama Infection in Llamas

Creator:: Puccetti, Jessica N.
Abstract:: Mycoplasma haemolamae is associated with mild to marked anemia in stressed, immune-suppressed, and debilitated animals, and may be found in low numbers in healthy animals. The continued presence of the organism, detectable by polymerase chain reaction (PCR)-based assay, may be associated with an underlying problem, such as stress or immune-suppression...

Characterization of Type III Effectors from Pseudomonas syringae pv. tomato DC3000

Creator:: Thireault, Caitlin
Abstract:: Many Gram-negative bacteria use a type III secretion system (TTSS) to establish a relationship with a host. Pathogens can use the secretion system as a way to deliver proteins known as type III effectors (TTEs) into a host cell and block host defense. The variation and redundancy of the type...

Method development for extraction and purification of dermal RNA from FVB/Nmice treated with environmental PAH mixtures

Creator:: Larkin, Andrew, Siddens, Lisbeth, and Krueger, Sharon
Abstract:: Epidermal RNA samples from FVB/N mice treated with PAH standards and environmental PAH mixtures were harvested and purified using Trizol extraction and RNeasy mini prep kit purification. Epidermal RNA integrity was low (RIN mean 3.5), indicating significant RNA degradation and the need to modify handling, collection, and processing of skin...

Differences in Societal and Behavioral Attitudes toward Skin Cancer between Japanese American and Japanese

Creator:: Nguyen, Vananh M.
Abstract:: The rate of melanoma among Asian American has been steadily increasing in the past five years, while in other Asian countries, such as Japan, the incident rate remains relatively the same. Does the culture and societal attitudes toward skin cancer make a difference in the incident rate of melanoma? This...

The Inhibition of a-Amylase and a-Glucosidase by Bioflavonoids

Creator:: Griffith, Anneke M.
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...

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...

Immunohistochemical characterization of melanomas in bigenic mice containing activated Cdk4 and keratinocyte specific ablation of Retinoid-X-Receptor alpha (RXRα) protein With international consideration of Differences in Societal and Behavioral Attitudes toward Skin Cancer between Japanese American and Japanese

Creator:: Nguyen, Vananh M.
Abstract:: OVERVIEW OF INTRODUCTION - This is a combined thesis for both disciplines of BioResource Research (BRR)Interdisciplinary and International Degree (ID) Programs OSU. The first chapter encompasses the BRR research, which is a preliminary study utilizing immunohistochemical method to characterize melanomas in bigenic mice with activated Cdk4 protein and Retinoid-X-Receptor α...

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.)...

Evaluation of Restored Wetlands in the Greater Willamette Valley

Creator:: Leondar, Elizabeth A.
Abstract:: ABSTRACT Wetlands are considered critically important in the delivery of ecosystem services such as water quality improvement, flood protection, and conservation of native biodiversity. A common measure of the effectiveness of these ecosystem services is denitrification, an anaerobic microbial process that converts nitrate (NO3-), a common water pollutant, into dinitrogen...

Telomere Binding Protein Antagonists for Stem Cell Therapy

Creator:: VanGarde, Aurora
Abstract:: Understanding the mechanisms through which stem cells self-renew is important for the development of new therapies to repair and restore damaged tissue. This research explores possible mechanisms of telomere mimic action and seeks to validate a new assay for evaluating telomere binding antagonists and studying the effects of telomere binding...

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...

EBB1, an AP2/ERF Transcription Factor, Promotes Transgenic Shoot Development in Populus

Creator:: Ree, Joseph
Abstract:: Recalcitrance to transformation makes genetic engineering of many valuable plants infeasible for practical use. Transitory host modification during transformation using transgenes offers a possible means of overcoming this obstacle. In prior work in our laboratory, the genes GA20ox7 and EBB1 were found to increase regeneration in vitro. In this project,...

Serum Haptoglobin as an Indicator for Calving Difficulties and Postpartal Diseases in Transition Dairy Cows

Creator:: Sabedra, Dominique A.
Abstract:: Abstract Haptoglobin is an acute phase protein that is elevated in response to tissue damage and infections in dairy cows. The objectives of this study were to evaluate whether serum haptoglobin concentrations in the first week after calving can indicate disease status and severity, and whether haptoglobin concentrations are elevated...

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...
