Kwon, Hyuk Jung (Texas A&M University, 2005-08-29)The objective of this study was to determine concentrations of amino acids and polyamines as well as nitric oxide (NO) and polyamine synthesis in the ovine conceptus (embryo/fetal and associated placental membrane). Ewes ...
-
Lassala, Arantzatzu Leticia (2009-05-15)This research was conducted to test the hypothesis that parenteralarginine supplementation is effective in enhancing birth weights of intrauterinegrowth restricted (IUGR) fetuses. Underfed and prolific ewes were used ...
-
Farmer, Jennifer Lynn (2009-05-15)Galectins are proteins with 15 known members found in nearly all living organisms. They share a conserved CRD that binds beta-galactoside sugars, and functions to cross-link glycoproteins as well as glycolipid receptors ...
-
Hanna, Carol Bailey McCormick (2009-05-15)The ability to create transgenic livestock is a tremendous benefit in scientific research for many disciplines including functional genomics, pharmaceutical synthesis and development of enhanced production animals. Transgenes ...
-
Jobgen, Wenjuan Shi (2009-06-02)This study was conducted to test the hypothesis that dietary arginine supplementation reduces fat mass in diet-induced obese rats. Male Sprague-Dawley rats were fed either low- or high-fat diets for 15 wks (16 rats/diet). ...

Minten, Megan A.; Bilby, Todd R.; Bruno, Ralph G. S.; Allen, Carolyn C.; Madsen, Crystal A.; Wang, Zeping; Sawyer, Jason E.; Tibary, Ahmed; Neibergs, Holly L.; Geary, Thomas W.; Bauersachs, Stefan; Spencer, Thomas E.; Ye, Xiaoqin (PloS One, 2013)
-
Black, Sarah Grace (2011-10-21)Endogenous retroviruses (ERVs) comprise a significant portion of the genome of all mammals and have been implicated in placental development in multiple species. The ovine genome contains approximately 27 copies of ...
-
Joyce, Margaret Mary (2009-05-15)Coordinated signals between the maternal endometrium and conceptus during the peri-implantation period are essential for the establishment and maintenance of pregnancy. In pigs, this involves estrogen secretion from ...
-
Rios, Jonathan Joseph (2009-05-15)West Nile virus (WNV), a member of the Flaviviridae family of RNA viruses, was first introduced to the United States in 1999 with rapid transmission across a variety of hosts throughout the continental states. Genetic ...
-
Navarrette, Ashley Elizabeth (2012-07-16)Infertility in dairy cattle remains a major economic loss to dairy producers. Identifying dairy cattle with superior genetic potential for improved fertility would increase dairy farm profitability. Dairy heifers were ...
-
Gray, Catherine Allison (Texas A&M University, 2005-08-29)Recurrent early pregnancy loss in the ovine uterine gland knockout (UGKO) ewe model manifests on Day 14 of pregnancy, indicating that endometrial secretions are critical for peri-implantation conceptus development. Therefore, ...
-
Song, Gwon Hwa (Texas A&M University, 2007-09-17)The peri-implantation period in mammals is critical with respect to survival of the conceptus and establishment of pregnancy. During this period of pregnancy, reciprocal communication between ovary, conceptus, and endometrium ...
-
Simmons, Rebecca M. (2010-07-14)Maternal contributions from the uterine endometrial luminal (LE) and glandular (GE) epithelia are unequivocally required to support ruminant conceptus growth and development, elongation and implantation. Therefore, studies ...
-
Greff, Sorin Meredith (2012-10-19)Maintenance of body temperature is one of the first and most important physiological processes that must be initiated after birth. Failure to sustain homeothermy leads to hypothermia and death. Indeed, in sheep, 40% of ...
-
Gao, Haijun (2010-07-14)This research was conducted to test the hypothesis that select nutrients including glucose, leucine, arginine and glutamine stimulate conceptus development by activating mTOR (mammalian target of rapamycin; HGNC approved ...
-
Ahn, Hyo Won (Texas A&M University, 2008-10-10)During early pregnancy in ruminants, progesterone (P4) from the corpus luteum (CL) and interferon tau (IFNT) from the conceptus act on the endometrium to regulate genes including interferon stimulated genes (ISGs) that are ...
-
Satterfield, Michael Carey (Texas A&M University, 2008-10-10)Progesterone is unequivocally required for the establishment and maintenance of pregnancy in all mammals studied. Its known functions are complex and encompass global changes in gene expression. Therefore, studies were ...
-
Minten, Megan A. (2012-10-19)Establishment of pregnancy in ruminants requires blastocyst development to form an elongated filamentous conceptus that produces interferon tau (IFNT), the pregnancy recognition signal, and initiate implantation. Blastocyst ...
-
Amstalden, Marcel (Texas A&M University, 2004-09-30)The physiological mechanisms through which nutrition mediates its effects in controlling reproduction are not well characterized. Both neural and endocrine components have been implicated in the communication of nutritional ...
