background: the present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (bual) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of f9sh, lh, prolactin, estrogen and progesterone. methods: twenty-four mature female rabbits divided into two test and control-sham groups. the animals underwent ovariohystrectomy...
Information on the reproductive biology of toadfish remains limited. In this study, we examined structure and development gonads in grunting Allenbatrachus grunniens (Linnaeus, 1758) using morphological, histological ultrastructural methods. The fish were collected from Pranburi River Estuary, Thailand, during annual period for species (January to December 2018). ovary was paired had elongated ...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
We investigated the expression of Ad4BP (also known as SF-1), a transcription factor regulating steroidogenic P-450 genes, in the steroidogenic tissues such as adrenal glands, testes and ovaries through the prenatal and postnatal life of rats. Ad4BP was detected in the primordial adrenal glands and gonads of the 13.5 day postcoitum (d.p.c.) fetus. After the appearance of Ad4BP, a steroidogenic ...
Distribution of estrogen receptor alpha (ERalpha) in the dominant follicle (DF) and corpus luteum (CL) at the three stages of estrous cycle in Japanese Black cows was evaluated by means of immunohistochemistry. Ovarian dynamics were observed twice daily using ultrasonography until the ovariectomy performed on Day 7 (First group, n=3), Day 10 (Second group, n=3) and Day 18 (Third group, n=3) (Da...
Women with polycystic ovary syndrome (PCOS) exhibit elevated androgen levels, oligoanovulation, infertility, and insulin resistance in metabolic tissues. The aims of these studies were to determine the role of insulin signaling in the development and function of ovarian theca cells and the pathophysiologic effects of hyperinsulinism on ovarian function in obesity. We disrupted the insulin recep...
