This book was released on 2010 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding conjugated linoleic acids (CLA) improves reproductive performance in dairy cows; however, the molecular mechanisms by which CLA improves reproduction are not well understood. Therefore, we evaluated whether the CLA isomers, trans-10, cis-12 CLA and cis-9, trans-11 CLA altered synthesis of steroidogenic hormones in bovine luteal cells by measuring concentrations of progesterone, PGE2, and PGF2[alpha] in conditioned medium and expression of genes involved in their synthesis. Confluent luteal cells from each of 4 cows were cultured in 0 [mu]M (control) or 0.1 [mu]M solutions of trans-10, cis-12 CLA and cis-9, trans-11 CLA in varying ratios (1:0, 0:1, 1:1, 2:1, 1:2, 5:1, 1:5, 9:1, or 1:9) for 48 h in the presence and absence of 1 [mu]M of the adenylate cyclase activator forskolin. Independent of CLA isomer and ratio, CLA decreased, compared to control, hormone concentrations of prostaglandin F2[alpha] (62.6 ± 10.5 vs. 50.4 ± 9.9 pg/mL; P[subscript Overall] = 0.003) and, in the absence of forskolin, prostaglandin E2 (61.2 ± 11.3 vs. 36.1 ± 10.1 pg/mL; P
Download or read book Pf2 and Pge2 Their Effects on Cell Respiration and Steroidogensis in the Bovine Corpus Luteum written by Charlotte B. Bacon and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are essential to the process of cell respiration and steroidogenesis. Both of these processes impact the viability of the corpus luteum, which is required to maintain early pregnancy. In cattle and other species, progesterone supports gestation, regulates embryogenesis and works in concert with estrogen to maintain the reproductive tract. Many investigators have sought to understand the processes that control regression of the corpus luteum. Two prostaglandins, PGF2a and PGE2, have been implicated in the functioning of this transient gland. It is accepted by most researchers that the primary luteolysin responsible for functional and structural demise of the corpus luteum is PGF2a. However, there is ambiguity between reported effects of PGF2a and PGE2 on whole cells and on animals in vivo. Therefore, the specific effects of these prostaglandins on oxygen consumption and progesterone secretion in mitochondria isolated from bovine corpora lutea are the focus of this dissertation. A decrease in oxygen consumption and a concomitant decrease in ATP may contribute to luteolysis. These in vitro studies using isolated mitochondria may help to resolve these questions. The first objective was to determine the influence of PGF2a and PGE2 on the oxygen consumption of mitochondria isolated from bovine corpora lutea. The second objective was to determine the effect of both of these prostaglandins on mitochondrial progesterone production. This is the first time that the direct effects of PGF2a on mitochondrial cellular respiration and steroidogenesis have been studied in the corpora lutea of any species. These results will expand information in the area of ovarian physiology and may clarify the roles of PGF2a and PGE2 in corpus luteum function.

Download or read book Periparturient Diseases of Dairy Cows written by Burim N. Ametaj and published by Springer. This book was released on 2017-12-21 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the results achieved so far by application of various biological systems (including genomics, transcriptomics, proteomics, and metabolomics) involved in the pathomechanisms and early diagnosis of periparturient diseases as specific biomarkers of disease in cattle. These emerging technologies help to extensively enhance our understanding of the etiology and pathogenesis of periparturient diseases of transition dairy cows. The book includes a chapter dedicated to ‘omics’ sciences and one that discusses the myths established in animal and veterinary sciences in recent decades and emerging, new paradigms. The diseases discussed include metritis, mastitis, laminitis, ketosis, rumen acidosis, periparturient immunosuppression, gastrointestinal microbiota and their involvement in disease, infertility, fatty liver, milk fever, and retained placenta. This book is intended for academics, veterinarians, animal nutritionists, researchers, and graduate students working in the field of ‘omics sciences’ with a special interest in dairy cattle health.

Download or read book Regulation of Implantation and Establishment of Pregnancy in Mammals written by Rodney D. Geisert and published by Springer. This book was released on 2015-10-08 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades technological advances in transcriptomics, proteomics, metabolomics, and glycomics along with the ability to selectively knockout genes of interest has greatly advanced our understanding of maternal-conceptus interactions that are essential for the establishment and maintenance of a successful pregnancy. This knowledge provides a foundation from which to build research endeavors to help resolve infertility, embryonic loss and recurrent abortion in humans, captive wild animals and important farm species. The present volume on “Regulation of Implantation and Establishment of Pregnancy in Mammals” brings together current reviews from leading experts to address the diversity of mechanisms by which species establish and maintain pregnancy. Implantation in rodents, dogs, pigs, cattle, sheep, horses, primates, humans and embryonic diapause in wild species are discussed. Reviews will provide current knowledge on the role of endometrial steroid receptors, adhesion factors, cytokines, interferons, steroids, prostaglandins, growth factors and immune cells involved with regulation of conceptus development.

Download or read book Male Fertility and Its Regulation written by E.S. Hafez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncontrolled population growth, a significant problem for many countries, depresses real living standards in all developing areas. As a corollary, un controlled population growth also stresses the ability to deliver adequate reproductive health care on both national and individual levels. To focus on this and related problems an International Congress to examine many aspects of male and female Reproductive Health Center Care was held on 10-15 October 1982 in Maui, Hawaii, USA. This volume is a result of the proceedings from the 'Symposium on Male Fertility and its Regulation' which was a part of the Reproductive Health Care Congress. The organizers of this symposium recognized the need to focus male reproductive understanding on contraceptive development. The ultimate objective was and still is to produce a variety of safe and effective male contraceptives similar to that accomplished in the female. Speakers were invited to review the state of the art in several areas related to male contra ception, reproductive toxicity and reproductive biology. The abstracts of these sessions were published as a special issue of Archives of Andrology (Vol. 9, No.1, August, 1982). Subsequently, this volume was assembled from key papers presented at the Symposium. Additionally, invited man uscripts from leaders in specific areas were solicited to provide additional range to the topics covered.
