Age-related response of isolated rat hepatocytes to menadione and (R)-[alpha]-lipoic acid

Creator:: Graves, Jason T.
Abstract:: Age-related decline in the capacity of endogenous antioxidant systems complicates pharmaceutical use by the elderly by potentially increasing the toxicity of some compounds. Of particular interest is chemical detoxification via glutathione (GSH) and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and GSH S-transferase (GST). These enzymes have been shown...

Identifying microRNAs by automated phylogenetic and structural analysis

Creator:: Smith, Daniel P.
Abstract:: Motivation: It can take considerable amounts of time and effort to use existing computational tools to analyze a small RNA sequence for the purpose of determining if it is characteristic of microRNA. It is similarly tedious to search for homologs to known microRNA sequences in the rapidly growing collection of...

Biochar as a cover for dairy manure lagoons: reducing odor and gas emissions while capturing nutrients

Creator:: Dougherty, Brian W.
Abstract:: Liquid manure lagoons are known to be sources of odor and environmentally damaging gas emissions. Land application of the manure slurry after storage can lead to detrimental nutrient runoff and leaching. Floating lagoon covers (biocovers) are one option for reducing emissions, but to date they have only been used to...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:: Stocking, Peter
Abstract:: Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Toxicity and Mutagenicity of Polycyclic Aromatic Hydrocarbons in Contaminated Soils using Mammalian In Vitro Assay

Creator:: Luker, George W.
Abstract:: There exists a growing need to establish a better in vitro model for evaluating PAH toxicity and carcinogenicity and to improve assessments of risk to human health, especially to the complex mixtures that exist in the environment. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants due to the incomplete combustion...

Monitoring Resistance in Onion Thrips to Insecticides, Lannate® and Exirel®, in the Treasure Valley of Eastern Oregon and Southwestern Idaho

Creator:: Sanchez, Kevin
Abstract:: To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...

Exploring the Growth Habits of Sweetpotatoes (Ipomoea batatas) in the Willamette Valley of Western Oregon

Creator:: Epps, Charlotte
Abstract:: Sweetpotatoes are a highly nutritious staple crop, playing an important role in global nutritional security. Although the majority of research in the United States (U.S.) focuses on the cultivation of the storage roots, both the leaves and roots are edible. Sweetpotatoes are indigenous to the Andes Region of South America;...

Enhancing Protocols to Improve Consistency Across Nanotoxicology Studies

Creator:: Luker, Sabrina R.
Abstract:: In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...

Fungal endophytes as source to combat bacterial infections

Creator:: Green, Jaimie R
Abstract:: Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...
