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...

The Storage of Grain and Aging of Flour, and Their Effects on Flour Functionality

Creator:: Miranda-Garcia, Omar
Abstract:: Flour aging is thought to occur naturally during storage of wheat flour. In soft-wheat it is hypothesized that aging may increase water absorption properties of the flour. The aim of this study was to determine if the absorption capacity of flour changes as a response to flour aging. Absorption was...

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...

Microbes may induce soil water repellency through the production of aliphatic constituents as a response to desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency may be influenced by microbes whereby they produce aliphatic constituents (non-wetting materials) that coat the soil particles when they are subjected to desiccation stress.

Preliminary Evidence that the Microbial Community may Produce Aliphatic Constituents and Induce Soil Water Repellency as a Response to Desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency is one cause of rill soil erosion and overland flow that results in the loss of fertile topsoil. Previous research suggests that since microbial growth depends on temperature/moisture and follows diurnal and seasonal cycles, a biological mechanism would be able to explain the observed seasonality and climate...

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...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Stomach Analysis of Top Aquatic Predators in a Headwater Stream Network

Creator:: Ain, Najma
Abstract:: Top predators play important roles in regulating communities and ecosystem processes in freshwater ecosystems. In the headwater stream network, it is crucial to understand the interspecific interaction between multiple predators. In Oregon forested ecosystems, Coastal Giant Salamander (Dicamptodon tenebrosus) and cutthroat trout (Oncorhynchus clarkii) are the top predators in many...
