Ovarian steroid hormones, mainly estrogen and progesterone, play a central role in the regulation of ovarian functions. The biological effects of progesterone (PR) and estrogen (ER) are dependent on the activation of both PR and ER isoforms. In the present study, we studied the cellular distribution and localization of progesterone receptor B (PR-B) and estrogen receptor alpha (ERα) in the bovi...

most serious problem that leads to reproductive system failure in both human and animals. Present study was carried out to investigate whether hydroalcholic extract of Dorema aucheri leaves could protect the male rats against lead-induced reproductive toxicity. Materials and Methods: Adult wistar rats were treated with 0.1% lead acetate in drinking water with or without 100, 200 and 400 mg/kg D...

the changes of total calcium content of persian sturgeon, acipenser persicus follicles were investigated during different stages of germinal vesicle migration. total calcium content increased during maturation and ripening of the oocytes i.e. migration of nucleus toward the animal pole. according to data, the total calcium of follicles with polarization index (pi: the ratio of the distance of t...

BACKGROUND Lymphoepithelial cyst (LEC) of the pancreas is a rare benign tumor. LEC with sebaceous glands of the pancreas is extremely rare, and its histogenesis remains unclear. CASE PRESENTATION We present a 66-year-old man with an incidental finding of a cystic lesion at the neck of the pancreas. Pancreatic juice cytology results and elevated serum carbohydrate antigen 19-9 and Dupan-2 leve...

this study was designed to evaluate the detrimental effect of atrazine (atr) on germinal epitheliums (ge) cytoplasmic carbohydrate (ch) and unsaturated fatty acids (ufa) ratio and to clarify the effect of atr on serum levels of fsh, lh, testosterone and inhibin-b (inh-b). the impact of atr exposure on total antioxidant capacity (tac), sperm dna packing and integrity were also investigated. seve...

background: previous researches about the effects of epididymal obstruction on the testes are contradictory, and the mechanism harmful effect of male duct system obstruction on seminiferous tubules still remains unclear. objective: the aim of this study was to investigate the effects of epididymal obstruction in prepubertal rats on the testis. materials and methods: 15 days of age, the young ra...

Although it has been known for over a century that sea urchin eggs are polarized cells, very little is known about the mechanism responsible for establishing and maintaining polarity. Our previous studies of microtubule organization during sea urchin oogenesis described a cortical microtubule-organizing center (MTOC) present during germinal vesicle (GV) migration in large oocytes. This MTOC was...

Submit Manuscript | http://medcraveonline.com Hakansson and Molin [4] suggests that microbial colonization of the GI tract affects the composition of GALT. Once the intestine is exposed to microorganisms, intraepithelial lymphocytes increase; germinal centers with immunoglobulin-producing cells arise rapidly in follicles and in the lamina propria and serum immunoglobulin concentrations increase...

Primary peritoneal papillary serous carcinoma is a rare primary malignancy diffusively involving the peritoneum of abdomen and pelvis. Epithelial ovarian cancers and primary peritoneal cancers arise from the common germinal epithelium which develops from the coelomic epithelium. Due to a common embryonic origin of the ovary and the peritoneum, carcinoma of the ovary and primary peritoneal carci...
