Effect of selenium source and supplementation rate in ewes on selenium status, passive immunity and growth performance of their lambs

Creator:: Stewart, Whitney C.
Abstract:: Selenium (Se) is an essential micronutrient of sheep. Supplementation is especially important in young lambs in order to prevent Se-deficiency signs. In the United States, the FDA regulates Se supplementation to ruminant diets at a level of 0.3 mg/kg Se (as fed basis). Questions still exist regarding what chemical form...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Membrane-type matrix metalloproteinase and inhibitor expression in sheep embryos and uterus

Creator:: Paul, Katy Beth
Abstract:: Expression of membrane-type matrix metalloproteinases (MT) and tissue inhibitors of matrix metalloproteinases (TIMP) was evaluated in sheep embryos and uterus during the pre- and peri-implantation periods. Embryos and uterine samples were surgically collected from ewes on days 9, 11, 13, and 15 of pregnancy (n=3 ewes/day) and of the estrous...

Expression of extracellular matrix proteins during blastulation in bovine embryos and factors affecting bovine endodermal cell outgrowth In Vitro

Creator:: CoreyAyne, Singleton
Abstract:: During early embryonic development, endodermal cells leave the inner cell mass (ICM) and migrate over an extracellular matrix (ECM), located on the blastocoelic side of the trophectoderm, to form a continuous layer of extraembryonic endoderm. Cell migration events depend on a family of cell surface proteins known as integrins that...

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...

Involvement of myristoylated alanine-rich c kinase substrate (MARCKS) protein in prostaglandin F2α- induced secretion of oxytocin by the bovine corpus luteum

Creator:: Salli, Ugur
Abstract:: Prostaglandin F₂α (PGF₂α), a stimulatory hormone of luteal oxytocin secretion, is known to activate protein kinase C (PKC); however, the intracellular signals that promote exocytosis of oxytocin remain to be elucidated. Myristoylated alanine-rich C kinase substrate (MARCKS), a protein specifically phosphorylated by PKC, crosslinks actin filaments associated with the inner...

Gene expression in the peripartum canine placenta

Creator:: Fellows, Elizabeth Jane
Abstract:: This research investigated gene expression in the canine placenta during the peripartum period. Previous studies have recognized molecular changes that occur in the placenta around the time of placental release in other species, but no study has looked at gene expression in the late gestation canine placenta. Of particular significance...

Fluorimetric analysis of intracellular calcium in high and low mobility fowl sperm

Creator:: Olson, Jill Wardell
Abstract:: Sperm mobility is defined as the net movement of a sperm population against resistance. Previous research demonstrated that the cell-permeant Ca2+ indicator rhod-2 AM gave a fluorescent signal predominantly in the head region of fowl sperm that differed between sperm mobility phenotypes. This thesis served to explore the role of...
