To study the temporal relationship between changes in hormone levels with the development of myometrial gap junctions, rats were sacrificed to collect uterine vein blood and uterine tissues daily from Day 15 to Day 20 of pregnancy, every 3 h on Day 21, during delivery, and 3 h after parturition. Levels of progesterone, estradiol and prostaglandin F2 alpha (PGF2 alpha) were measured by specific ...
During cholestatic liver diseases, cholangiocytes express neuroendocrine phenotypes and respond to a number of hormones and neuropeptides by paracrine and autocrine mechanisms. We examined whether the neuroendocrine hormone progesterone is produced by and targeted to cholangiocytes, thereby regulating biliary proliferation during cholestasis. Nuclear (PR-A and PR-B) and membrane (PRGMC1, PRGMC2...
Catheters were placed in the carotid artery via a facial artery (n = 12) and in the ovarian vein (n = 12), and, in conjunction, electromagnetic flow meters were placed around the ovarian artery (n = 6) in cyclic beef cows. Androstenedione was quantitatively the highest and dehydroepiandrosterone the lowest of the ovarian androgens measured. Ovarian androgens were correlated positively with each...
Farm trials were conducted to determine if the calving rate was different for control cows inseminated with frozen semen at estrus in comparison to cows treated with progesterone for 12 days and bred at the ensuing estrus. Intravaginal silastic coils impregnated with progesterone were used and an injection of 5 mg estradiol benzoate and 50 mg progesterone in corn oil was given at the time of in...
BACKGROUND Progesterone levels are higher in placental barriers during pregnancy, but the effect of progesterone on human immunodeficiency virus type 1 (HIV-1) infection in placental cells has not been addressed. We hypothesize that progesterone may affect HIV infection. METHODS Purified trophoblastic cells and trophoblastic cell lines were infected or transfected with HIV-1, and the effect o...
background: the value of serial measurement of serum ß subunit of human chorionic gonadotropin (ßhcg) and ultrasonography in the early diagnosis of ectopic pregnancy has well established. objective: the objective of this study was to explore the diagnostic value of raising level of serum ßhcg, single measurement of progesterone (p) and estradiol (e2) in early diagnosis of ectopic pregnancy. mat...
Background: After puberty, asthma becomes more prevalent and severe in women as compared to men. Researchers are suggesting a role for sex hormones impact on inflammatory mediators. Physical activity decreases inflammation and sex hormone levels and improves pulmonary functions in asthmatic patients. Therefore, the aim of the present study was to investigate the effect of 12 weeks of aerobic ex...
Plasma progesterone concentrations measured by radioimmunoassay in the Natal clinging bat remained below 2.01 ng/ml during lactational anoestrus but increased significantly during the period of delayed implantation. Values peaked at implantation but were followed by a significant decrease thereafter. Concentrations remained low (less than 6.0 ng/ml) during the initial period of fetal developmen...
abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
BACKGROUND To assess the impact of luteal phase support on the expression of estrogen receptor (ER) alpha and progesterone receptors B (PR-B) on the endometrium of oocyte donors undergoing controlled ovarian hyperstimulation (COH). METHODS A prospective, randomized study was conducted in women undergoing controlled ovarian hyperstimulation for oocyte donation. Participants were randomized to ...
