The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

Creator:: McNeel, Anthony Kent
Abstract:: Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

The Influence of Wildfire and Invasive Vegetation on Mule Deer

Creator:: Schuyler, Elizabeth
Abstract:: The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...

Disease invasion dynamics : brucellosis and tuberculosis in African buffalo (Syncerus caffer)

Creator:: Gorsich, Erin E.
Abstract:: Emerging infectious diseases in wild animals threaten global biodiversity as well as domestic animal and human health. Their unprecedented increase in conjunction with anthropogenically induced range shifts of endemic pathogens exposes hosts to novel parasite combinations, lending urgency to research on disease dynamics in wildlife systems. In natural populations, hosts...

An appraisal of risks and benefits in the provision of selenium for beef cattle

Creator:: Hathaway, Ronald L.
Abstract:: Three experimental grazing trials were conducted to explore the hypothesis that in the Klamath Basin, a higher level of selenium supplementation is necessary than those proven adequate elsewhere. Two forage species were investigated: Festuca arundinaeca and Agropyron repens, in 0.61 hectare plots, both grown in a selenium deficient soil area....

Comparison and analysis of small area estimation methods for improving estimates of selected forest attributes

Creator:: Goerndt, Michael E.
Abstract:: One of the most common practices regarding estimation of forest attributes is the partitioning of large forested subpopulations into smaller areas of interest to coincide with specific objectives of present and future forest management. New estimators are needed to improve estimation of selected forest attributes in small areas where the...

Biological oxidation of sorbitol

Creator:: Cummins, Joseph Thomas
Abstract:: The oxidation of sorbitol by soluble extracts of A. suboxydans proceeds by two pathways depending upon which pyridine nucleotide is present. In the presence of TPN, sorbose is formed. In the presence of DPN fructose is produced. Both products of the oxidation of sorbitol have been identified by paper chromatography,...

Characterization of the Mechanisms of Action and Molecular Targets of Hop-derived Flavonoids in the Mitigation of Obesity-related Metabolic Impairments

Creator:: Paraiso, Ines L.
Abstract:: Obesity is a complex multifactorial disease resulting from excessive energy intake compared to energy expenditure. The excess energy is mostly stored as fat in enlarged adipocytes, but some lipids may infiltrate other organs such as the liver to form ectopic fat. Adipose tissue and ectopic fat produce and secrete a...

Drug Discovery and Chemical Ecology Investigations of Specialized Metabolism in Tolypocladium and Paraisaria

Creator:: Tehan, Richard M.
Abstract:: Since the discovery of penicillin in 1928, the fungal kingdom has remained a fertile source for the discovery of new, biologically active, natural products. Further, as natural products continue to be discovered from fungi, a deeper understanding of the critical role of specialized metabolism in fungal ecology is afforded. The...

Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...
