the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
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...
در این مطالعه تغییرات هورمون های استروئیدی 11-ketotostesterone (11-kt)، testeosterone (t)، 17?-estradiol (e2) و 17?-hydroxyprogesterone (17?-ohp) و توسعه گنادی تاسماهی سیبری acipenser baerii در محیط محصور بررسی شد. در ابتدای دوره (تیر1388) با استفاده از بیوپسی جنسیت و مرحله رسیدگی 16 ماهی (9 عدد نر و 7 عدد ماده) تعیین شد. با پیشرفت مرحله رسیدگی جنسی (در هر دو جنس تاسماهی سیبری) غلظت 17?-ohp رون...
Background & Aims: Adult neurogenesis occurs in the two main areas of the brain of most mammalian species in; sub ventricular zone, and the dentate gyrus of the hippocampus. Many factors such as 17-β estradiol affect neurogenesis in the hippocampus. The aim of this study was to investigate the effect of exogenous 17-β estradiol on neurogenesis in the ovariectomized (OVX) mice. Materials & Meth...
The purpose of this study was to determine the effects of 17-beta-estradiol on area postrema neuronal activity in vivo and on area postrema potassium currents (IK) in vitro. In anesthetized rats, intravenous injection of 17-beta-estradiol (10 ng/kg bw) -inhibited area postrema neuronal activity in 8/8 neurons tested. The averaged firing rate decreased from 2.9 +/- 1.1 to 1.1 +/- 0.3 Hz. The inh...
Introduction: The 17β-estradiol acts as a neurosteroid in the brain and modulates nociception by binding to the estrogen receptors and also by allosteric interaction with other membrane-bound receptors like glutamate receptors. Paragigantocellularis lateralis nucleus (LPGi) is one of the important brain regions implicated in the pain modulation. So, this study was designed to evaluate the ...
OBJECTIVE To evaluate the influence of 2 continuous combined estrogen-progestin replacement products, compared with unopposed estrogen and placebo, on cardiovascular risk markers in postmenopausal women in a randomized, double-blind, placebo-controlled trial. METHODS Two hundred seventy healthy postmenopausal women were randomly assigned to 1 of 4 treatment groups: placebo, unopposed 17-beta ...
OBJECTIVE The influence of 17-beta-estradiol on the stress response of Candida albicans was studied. METHODS The survival of clinical isolates of C. albicans treated with 17-beta-estradiol after heat and oxidative stress was measured by viable plate counts. Cellular proteins were analyzed via SDS-PAGE. RESULTS The heat stress response induced by 17-beta-estradiol in C. albicans grown at 25 ...
introduction: 17&beta-estradiol; modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. in addition to its autonomic functions, paragigantocellularis lateralis (lpgi) is involved in the pain modulation, too. the aim of the current study was to investigate the involvement of the membr...
