در پژوهش کنونی تعداد نورونهای تولید کننده هورمون آزاد کننده گونادوتروپین ( gnrh ) در ناحیه پیشبینایی ( poa ) هیپوتالاموس در گامههای چرخه فحلی میش مورد مقایسه قرار گرفت. هیپوتالاموس چهار گروه میش (3= n ) تخمدانبرداری شده، پرواستروس، استروس و لوتئال بعد از پرفیوژن خارج شد. تعداد نورونهای تولید کننده gnrh در ناحیه poa با استفاده از روش ایمیونوهیستوشیمی بین چهار گروه مقایسه شد. نورونهای gnrh ...
Pregnant rats were injected with 4 mg of testosterone propionate (TP) from days 15 to 22 of pregnancy or a single dose of 4 mg TP on day 17 or 21 of pregnancy. Female offspring treated with TP or the vehicle prenatally were sacrificed at 90 days of age. The volume of the cluster of intensely stained neurons in the medial preoptic area, the "sexually dimorphic nucleus of the preoptic area" (SDN-...
Binding of [3H]naloxone ([3H]NAL) to brain membranes was quantified by Scatchard analysis using two methods of separating bound from free [3H]NAL. In the centrifugation method, membranes that were soluble at 1,000 x g, but sedimented at 20,000 x g, were incubated with [3H]NAL. For filtration, all membranes that sedimented at 20,000 x g were incubated and filtered through glass filter fibers. No...
The preoptic area (POa) of the rostral diencephalon supplies the neocortex and the amygdala with GABAergic neurons in the developing mouse brain. However, the molecular mechanisms that determine the pathway and destinations of POa-derived neurons have not yet been identified. Here we show that Chicken ovalbumin upstream promoter transcription factor II (COUP-TFII)-induced expression of Neuropil...
Pyrazinamide (PZA) is a first-line tuberculosis drug that inhibits the growth of Mycobacterium tuberculosis via an as yet undefined mechanism. An M. tuberculosis laboratory strain that was auxotrophic for pantothenate was found to be insensitive to PZA and to the active form, pyrazinoic acid (POA). To determine whether this phenotype was strain or condition specific, the effect of pantothenate ...
The effect of protection from sheep grazing on indigenous plant species in relatively mesic, strongly modified Poa cita grassland, was examined using paired grazed and ungrazed sites. Ungrazed sites, fenced at times ranging from four to more than 24 years ago, had fewer species, lower indigenous cover and lower tussock density than adjacent grazed sites. The dominance of adventive species, part...
A reduction of heat loss to the environment through increased cutaneous vasoconstrictor (CVC) sympathetic outflow contributes to elevated body temperature during fever. We determined the role of neurons in the dorsomedial hypothalamus (DMH) in increases in CVC sympathetic tone evoked by PGE2 into the preoptic area (POA) in chloralose/urethane-anesthetized rats. The frequency of axonal action po...
This study aimed to investigate the efficacy and safety of celecoxib 24 hours preoperative, 1 hour preoperative, and 4 hours postoperative administration in patients with arthroscopic knee surgery (AKS).In all, 206 patients who underwent AKS were consecutively recruited and randomized into 3 groups: (1) early preoperative analgesia group (EPEA), celecoxib 400 mg 24 hours preoperative administra...
BACKGROUND Highly Individualized Egg Retrieval (HIER), defined as age-specific early oocyte retrieval (ER), has been demonstrated to avoid premature luteinization in women ≥43. We here investigated whether HIER also applies to younger women with premature ovarian aging (POA), and what best lead follicle size should be for administration of ovulation-triggers. METHODS Fifty-six women ≥43, and ...
