Generation of Kisspeptin Cell Lines to Investigate the Sex Steroid-Mediated Initiation of Puberty

Creator:: Jacobs, Dakota C.
Abstract:: Mammalian female reproduction requires preovulatory surges of gonadotropin-releasing hormone (GnRH) from neurons in the preoptic area (POA) of the hypothalamus, initiated by elevated estradiol (E₂). Rising E₂ activates a subset ofsexually dimorphic Kisspeptin neurons in the female, located in the anteroventralperiventricular nuclei (AVPV). Conversely, E₂ negative feedback is mediated by...

Developing Trap and Kill Technologies to Improve Management of the Western Spotted Cucumber Beetle (Diabrotica undecimpunctata undecimpunctata) and the Western Striped Cucumber Beetle (Acalymma trivittatum)

Creator:: Alderman, Katie
Abstract:: The western spotted cucumber beetle (Diabrotica undecimpunctata undecimpunctata) and the western striped cucumber beetle (Acalymma trivittatum) are pests of many crops, including vegetable, fruit, and nursery crops. Pesticides are commonly used to control this pest. Trap and kill technologies are under development as use in an alternative control for cucumber...

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...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:: Arnold, Madison A.
Abstract:: Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Incorporation of aerodynamic and boundary layer resistances in determining initial evaporation rates of pesticides from turf grass

Creator:: Conway, Michael
Abstract:: Evaporative loss rates of pesticides, following application to turfgrass, were measured using the Backward-Time Lagrangian stochastic Dispersion model (Flesch, Wilson, Journal of Applied Meteorology, 34, pp. 1320-1332. All pesticides were applied to a 22.8 m x 22.8 m orchard ryegrass turf plot near Corvallis, Oregon. Solar radiation, ambient temperature, surface...

Impact of lignin on efficiency of small-scale enzymatic hydrolysis of lignocellulosic biomass

Creator:: Potapchuk, Angelica
Abstract:: Energy production and consumption is a major environmental and economic concern in the world today. Biofuel produced from lignocellulosic biomass is being explored as an alternative energy source to petroleum. Lignocellulosic biomass is comprised of cellulose, hemicellulose, and lignin. To produce biofuels, lignocellulosic biomass must be broken down to expose...

Detection and Identification of Acetaminophen (Tylenol) Metabolites using Liquid Chromatography High Resolution Mass Spectrometry (LC-HRMS/MS) Analysis

Creator:: Sanchez, Karina M.
Abstract:: Acetaminophen (APAP) is a commonly used analgesic and antipyretic drug that can cause liver injury, liver necrosis, and liver failure. APAP-induced liver failure (AILF) is associated with depletion of glutathione and the increased formation of APAP protein adducts from the toxic NAPQI metabolite. There is a hypothesized detoxifying pathway where...

Immunohistochemistry Studies of Tumor Necrosis Factor Αlpha and Interferon Gamma Expression in Pseudocapillaria tomentosa Infected and Uninfected Zebrafish

Creator:: Lo, Lalee C.
Abstract:: Tumor necrosis factor alpha (TNF α) and interferon gamma (IFN γ) were initially recognized as inflammatory mediators produced by immune cells in response to infectious agents or foreign material. (1,5) However, over the past decade much research in mammalian species has indicated that these proteins also play key roles in...

Toxicity Screening of Polycyclic Aromatic Hydrocarbons (PAHs) in Primary Human Bronchial Epithelial Cells

Creator:: Amador, Samantha B.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a known class of chemicals that are linked to a multitude of adverse health outcomes. There are over 1,500 of these chemicals across various families and subgroups. 16 of these PAHs, known as parent PAHs, are identified by the EPA for focused risk assessment within...

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...
