Both Day 14 corpora lutea (CL) of the estrous cycle and Day 200 CL of pregnancy secrete detectable prostaglandin E (PGE) and prostaglandin F2 alpha (PGF2 alpha) in vitro. Corpora lutea from Day 200(More)
The affinity and specificity of an antagonist of oxytocin, [1-D(CH2)5,Tyr(ME)2,Thr4,Tyr-NH2(9)]ornithine vasotocin (OTA), to oxytocin receptors (OTR) in bovine gestational endometrium was determined(More)
Secretion of progesterone by Day 14 bovine corpora lutea (CL) of the estrous cycle and Day 200 CL of pregnancy was evaluated in vitro to determine what regulates secretion of progesterone by CL of(More)
The effects of PGE2, PGF2alpha, trilostane, RU-486, PA, INDO, MER-25, PGE2, or PGF2alpha + PA on secretion of progesterone, PGE2, or PGF2alpha by bovine corpora lutea (CL) of mid-pregnancy in vitro(More)
The major objective of this experiment was to determine whether the bovine placenta could be stimulated to secrete progesterone, since the bovine placenta secretes little progesterone when the corpus(More)
In rodents and pigs, leptin stimulates the release of gonadotropin-releasing hormone (GnRH) from hypothalamus, gonadotropins from adenohypophyseal (AP) explants and cells, and luteinizing hormone(More)
