Characterization Of Ovine Ileal Epithelial And Myofibroblast Cell Lines And Their Role In Innate Immunity, Shaurav Bhattarai
Electronic Theses and Dissertations
Development of continuous cell lines has been an indispensable tool for studying disease pathogenesis at cellular and molecular level. Intestinal epithelial cells serve as a barrier between the luminal contents and internal tissue and face unique challenge in maintaining homeostasis. Any form of disruption in the uppermost intestinal epithelium exposes underlying intestinal subepithelial myofibroblast (ISEMF) cells to the luminal content, which results in the generation of immune responses from ISEMF cells. Our main goal was to establish and characterize intestinal epithelial and myofibroblast cell lines from a 3-day old sheep. ISEMF cells play significantly important role in wound healing, tissue …

Enhanced Beta (Β) Glucan Beverages – Evaluation Of Satiety, Nutrition, And Shelf Stability, Beatrice Serwaa Manu
Enhanced Beta (Β) Glucan Beverages – Evaluation Of Satiety, Nutrition, And Shelf Stability, Beatrice Serwaa Manu
Electronic Theses and Dissertations
Oats and barley are unique cereals owing to their nutritional and health benefits. Soluble dietary fiber components, especially β-glucan found in both grains, have been associated with the reduction of cholesterol, normalization of blood sugar levels and suppression of hunger. These nutritional and therapeutic attributes are ideal for production of novel and more diversified food products from these cereals. β-glucan, however, imparts high viscosity in food systems particularly in high moisture foods, thus impairing their sensory characteristics. Reduced viscosity oat-barley beverages, using partial enzyme and acid hydrolysis, may fill a void in the market segment and yet serve as effective …

Electronic Theses and Dissertations
Auxin and cytokinin are major plant hormones that orchestrate plant development. These hormones are involved in cell division and differentiation and their spatio‐temporal balance controls organ initiation and maturation. Even though independent transcriptional responses to these hormones have been characterized, their concomitant outputs have not been described. We developed methodology to determine auxin-cytokinin relative output (ACRO) ratios at cellular resolution. Hormone-specific fluorescent markers that localize to the nucleus were used to report transcriptional outputs of auxin and cytokinin. Multiphoton microscopy and image data processing were used to quantify their relative ratio at cellular level in three-dimensional tissue volumes. This strategy …
Epidemiological Investigations Of Bighorn Sheep Respiratory Disease And Implications For Management, Brandi L. Felts
Epidemiological Investigations Of Bighorn Sheep Respiratory Disease And Implications For Management, Brandi L. Felts
Electronic Theses and Dissertations
Infectious respiratory disease has long been identified as the cause of bighorn sheep (Ovis canadensis) historical declines and extirpations, and Mycoplasma ovipneumoniae (Movi) is the primary pathogen inducing disease and mortality. Population-level effects of pneumonia events range from mild to extirpation. Variable individual response to pathogen exposure emerges from dynamic interactions between competing evolutionary processes within the host and pathogen. Understanding impacts of this evolutionary warfare is essential to assessing long-term impacts of pathogen invasion and developing appropriate countermeasures to protect population health. Freeranging populations are faced with spillover infections from domestic sheep and goats as well as …

Winter Patch Grazing, Patch Burn Grazing, And Bird Communities In Western South Dakota, Jennifer Lutze
Electronic Theses and Dissertations
Ground nesting bird species are on a considerable decline and research efforts are being made to increase these populations throughout the Great Plains. Ground nesting bird communities found in the Northern Great Plains are driven greatly by varying amounts of cover and area size. Past research implemented patch-burn grazing to increase structural heterogeneity and to increase grassland bird habitat in the tallgrass prairie. While bird populations were very responsive to this management in the Northern Great Plains fire management is viewed negatively, especially for Midwest cattle ranchers. We implemented research to determine if winter-patch grazing on mixed grass prairie could …

Behavioral Chronopharmacology Of Cannabinoids In Young And Aged Mice, Erik Lewis Hodges
Behavioral Chronopharmacology Of Cannabinoids In Young And Aged Mice, Erik Lewis Hodges
Electronic Theses and Dissertations
The overarching goal of this research is to explore the biological mechanisms of aging and formulate novel therapeutic approaches to mitigate age-related impairments. The presence and pervasiveness of ~24 hour (circadian) rhythms in molecular and behavioral dynamics suggests that the mechanisms regulating these rhythms are integral to biological aging and possibly amenable to therapeutic interventions. Based on evidence presented in this dissertation, we conclude that the endocannabinoid system is a mediator of both central and peripheral circadian physiology. Additionally, the hormetic pharmacological properties of the synthetic cannabinoid CP55940 suggest that bidirectional modulation of circadian rhythms via cannabinoids is possible. Chapter …
