Fatty Acids And Lipogenesis In Ruminant Adipocytes, Taber Burns
Fatty Acids And Lipogenesis In Ruminant Adipocytes, Taber Burns
All Dissertations
Obsesity, the excess deposition of white adipose tissue, is a growing problem in the U.S. and other developed countries. Formerly thought to be inert, adipose tissue is now recognized as a dynamic endocrine organ with its secretion of adipokines and a newly proposed class hormone class 'lipokine'. Adipocytes are the functional unit of adipose tissue and can influence the tissue through hyperplasic and hypertrophic growth. In order to investigate the mechanisms involved in adipogenesis and lipogenesis of adipose tissue, stromal vascular cultures were isolated from adipose tissue of finishing cattle for use in experiments.
There is a positive relationship between …
Effects Of Dietary Supplementation Of Conjugated Linoleic Acid In Horses, Shannon Headley
Effects Of Dietary Supplementation Of Conjugated Linoleic Acid In Horses, Shannon Headley
All Theses
Conjugated linoleic acid (CLA) reduces inflammation via the inhibition of cyclooxygenase II , thus reducing prostaglandin E2 (PGE2) production. Conjugated linoleic acid has a suggested osteoclast-suppressive role in bone remodeling and osteoarthritis, which are dependent on bone resorptive stimulator PGE2. Bone resorption marker, deoxypyridinoline (DPD), and bone formation marker, bone alkaline phosphatase (BAP), have been modulated by CLA supplementation in other species. Recent research in equine exercise physiology investigated dietary supplementation of polyunsaturated fatty acids as a possible prevention and treatment for osteoarthritis, but CLA supplementation has putative effects on skeletal function or inflammation in horses has not been reported. …
Biohydrogenation Of Docosahexaenoic Acid, Catherine Klein
Biohydrogenation Of Docosahexaenoic Acid, Catherine Klein
All Dissertations
Pathways of docosahexaenoic (DHA) biohydrogenation are not known; however, DHA is metabolized by ruminal microorganisms. The addition of DHA to the rumen alters the fatty acid profile of the rumen and milk and leads to increased trans-18:1 isomers, particularly trans-11 18:1 and 22 carbon fatty acids. This study included four in vitro experiments to identify if these are produced from DHA or if they come from other sources that are affected by DHA. In each experiment, ruminal microorganisms collected from a lactating Holstein cow were incubated in batch cultures for 0, 6, 24, and 48h and a uniformly 13C DHA …
A Survey Of Heterologous Expression Systems For The Production Of Bovine Follicle Stimulating Hormone And Luteinizing Hormone, Marcia Hesser
A Survey Of Heterologous Expression Systems For The Production Of Bovine Follicle Stimulating Hormone And Luteinizing Hormone, Marcia Hesser
All Dissertations
Follicle stimulating hormone (FSH) and luteinizing hormone (LH) are glycoprotein gonadotropins from the anterior pituitary gland that are involved in reproductive functions. They are heterodimeric proteins that share a common α-subunit that is highly conserved amongst mammalian species, and is also conserved across this family of proteins. The β-subunit confers receptor specificity and is distinct. Recombinant gonadotropin expression would be an important advance for the bovine superovulation industry, as there are a number of disadvantages associated with the currently used pituitary-derived gonadotropins. For example, these pituitary products are contaminated with other proteins including hormones, exhibit batch-to-batch inconsistencies, and harbor the …
