Background: Breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. Assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. The purpose of this study was to determine the relationship between estrogen and progesterone receptors with Her-2, Ki67, P53, and clinicopathologica...

Preterm deliveries is the major contributors of neonatal mortalities and under 5 age group morbidities. Excessive use Progesterone its supplements, antenatal steroidal cover tocolysis prevents this. In this study, there has been made an attempt to study perinatal outcome both mother neonate revolving around premature by using two different routes for progesterone administration. A prospective w...

Taenia solium cysticercosis is a health problem in underdeveloped and developed countries. Sex hormones are involved in cysticercosis prevalence in female and male pigs. Here, we evaluated the effects of progesterone and its antagonist RU486 on scolex evagination, which is the initial step in the development of the adult worm. Interestingly, progesterone increased T. solium scolex evagination a...

Progesterone is an anxiolytic steroid that could play a role in the regulation of anxiety in women. However, the mechanism by which progesterone decreases anxiety is incompletely understood. Progesterone affects the function of the brain by two distinct mechanisms. Progesterone regulates reproductive behavior by activating intracellular progesterone receptors (PRs). In addition, progesterone is...

background: there are some controversial data on application of progesterone and progesterone plus estrogen at luteal phase. objective: to investigate the effects of different luteal support hormones on the alkaline phosphates (alp) activity in the endometrial epithelium and endometrial thickness during superovulation process for obtaining the optimized endometrial receptivity in animal model. ...

Dispersed bovine placental cells (fetal cotyledon and maternal caruncle) were shown to synthesize progesterone. To determine if their steroidogenic activity could be modulated by a cyclic nucleotide-mediated process, we added luteinizing hormone, 8-bromoadenosine 3',5'-monophosphate, 8-bromoguanosine 3',5'-monophosphate, adenosine, or cholera toxin to dispersed cells from placentomes of 100-283...

BACKGROUND Progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic gonadotropin (hCG), which is produced by the corpus luteum. This occurs in the luteal phase of the menstrual cycle. In assisted reproduction techniques (ART) the progesterone or hCG levels, or both, are low and the natural process is insufficient, so the luteal phase is sup...

the present study was carried out to characterize the cervical mucus (cm) collected when inseminating holstein cows and to relate the secretion pattern with pregnancy. the mucus was collected from mid-cervix of 64 cows with spontaneus estrus (se) and induced estrus (ie). the quantity, pattern and consistency of the mucus, ph, arborization patterns and the sperm motility were observed. the level...
