The role of zinc in the molecular and cellular events in the prostate

Creator:: Yan, Michelle
Abstract:: Zinc is an essential mineral that is integral to many proteins and transcription factors that regulate key cellular functions. The normal prostate accumulates high concentrations of zinc; however, malignant tissues have significantly lower zinc levels. This unique relationship between zinc and the prostate has sparked interest in the role of...

The function of zinc in the maintenance of DNA integrity in vivo

Creator:: Song, Yang
Abstract:: Approximately 12% of Americans do not consume the amount of zinc equal to the Estimated Average Requirement for zinc and could be at risk for marginal zinc deficiency. Zinc is an essential component of proteins in the defense against oxidative stress and DNA damage repair. Specifically in the prostate, zinc...

The effect of ration formulation on the subsequent generation of volatile gases and odors from bovine waste

Creator:: Kellems, Richard O.
Abstract:: The objective of this study was to determine the effect that ration formulation has on volatilization of gases and offensiveness of the odor associated with the wastes produced from Holstein replacement heifers. Six separate experiments were conducted to study the relationships between different variables on the release of hydrogen sulfide,...

Diclofop in runoff from agricultural watersheds in a high winter rainfall zone

Creator:: Hickman, John Spencer
Abstract:: Diclofop-methyl [me yl 2-(4-(2,4-dichlorophenoxy) phenoxy) propanoate] hydrolysis, degradation, and leaching were studied in field and laboratory experiments. Greater than 75% of the applied diclofop-methyl hydrolyzed to diclofop in 2 days at 4°C, the prevailing soil temperature during western Oregon winters. Degradation beyond the diclofop molecule, also an active herbicide, was...

Deposition and persistence of polynuclear aromatic hydrocarbons after slash burning clear-cut sites in Oregon

Creator:: Sullivan, Timothy Joseph
Abstract:: Research has been completed which identifies qualitatively and quantitatively the deposition, persistence and fate of polynuclear aromatic hydrocarbons (PNAH) on burned clear-cut sites in Oregon. Eight PNAH were identified and quantified in post-burn litter samples taken from four slash-burned sites. Deposition of lower molecular weight, 3-4 ring compounds was considerably...

Short-term fate of xenobiotic substances in pesticide deposits

Creator:: Bentson, Kenneth Paul
Abstract:: An experimental protocol to determine the effects of temperature and light on the dissipation of xenobiotic substances in pesticide deposits is presented. A factorial design laboratory experiment is used to develop isothermal models of the dissipation of compounds over time in authentic pesticide deposits on excised leaves arid glass microscope...

Transcriptional regulation of mouse epidermal permeability barrier development and homeostasis by Ctip2

Creator:: Wang, Zhixing
Abstract:: Skin is the largest organ in the body that protects the organism from environmental, chemical and physical traumas of each passing day. The protective skin epidermal permeability barrier (EPB) is formed within the exterior layers of the epidermis, which are regularly sloughed off and repopulated by movement of inner cells....

Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:: Chibwe, Leah
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

Application of nonequilibrium ecology to managed riparian ecosystems

Creator:: Stringham, Tamzen K.
Abstract:: Seasonal trends in water table level and soil moisture for four plant community types within an irrigated eastern Oregon riparian zone were described. Aboveground biomass, species composition, litter, percent bareground and percent basal cover of key plant species and life forms were measured. The relationship between water table levels and...

Poly- and perfluorinated alkyl substance release from landfills and landfill model reactors

Creator:: Allred, Brent McKay
Abstract:: Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...

Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

Creator:: Guild, Liane S.
Abstract:: Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resultant burning emissions and terrestrial aboveground elemental pool losses during a period of early colonization in the vicinity of Jamari,...
