introduction: neurohormones like testosterone and estradiol have an important role in learning and memory. the hippocampus is essentially involved in learning and memory, and is known to be a target for estradiol actions. estrogen receptors (ers) are highly expressed in ca1 of rat hippocampus, and mediate the effects of estrogen on learning and memory. estradiol receptor belong to a family of t...

To investigate how estrogen level on the endometrial transformation day for hormone replacement therapy-frozen-thawed embryo transfer cycle influences pregnancy outcome. A retrospective analysis was conducted clinical data from 772 patients who underwent therapy-frozenthawed between January 2016 and 2020 in Reproductive Medicine Center, Maternal Child Health Hospital of Shaoguan City. The were ...

the study was undertaken to compare the efficacy of an estradiol-17β + cidr based protocol with the conventional ovsynch + cidr based protocol for synchrony of wave emergence and ovulation in murrah buffalos. in group i (n=25), on day 0 (beginning of experiment), buffaloes were administered a cidr device (1.38 g p4) and concurrently received 1.5 mg e-17β. on day 9, the cidr was removed and a pr...

background: the uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. as such, uterine stem cells have been studied in recent years. transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. objective: the present research evaluated the mrna expression of oct4 and sox2 in the uterine tissues of ovariectomized mice tr...

Estradiol valerate (Exogenous estrogen) is a synthetic ester and is also a female estrogen hormone. There arestudies showing that estradiol may have anticancer effects. This study was performed to reveal the effects ofexogenous estrogens on the viability of cervical cancer cells in cell culture. We used Hela cells as our cell linein this study. Hela cells were exposed to 0.0001, 0.001, 0.01, 0....

Hormones have been used to change phenotypic sex in many fish species. However, information specific changing brown trout Salmo trutta is lacking. This study compared the effectiveness of two different 17β-estradiol (estradiol) concentrations (20 mg/kg and 30 mg/kg) fed for 60 days, beginning at initial feeding. At 456 days post-initial feeding, 20 treatment groups were 84% 86% female, respecti...

Introduction: Beside its autonomic functions, the nucleus paragigantocellularis lateralis (LPGi) is involved in the descending pain modulation. 17β-Estradiol is a neuroactive steroid found in several brain areas such as LPGi. Intra-LPGi microinjection of 17β-estradiol can elicit the analgesic responses. 17β-Estradiol modulates nociception by binding to estrogenic receptors as wel...
