Leptin, the 16-kDa product of the obese (ob) gene, primarily secreted from adipose tissue, has been implicated to play an important role in the regulation of food intake and energy expenditure. This study investigated protective effect of leptin on trichostatin A-induced apoptotic on in vitro maturation ratio of buffalo oocytes. Ovaries were collected from abattoir and were transported...

Background: Since the freezing method was offered, much effort has been done to improve the freezing conditions in different studies and the impact of different freezing methods and mediums on oocyte, embryo and ovarian tissues has been examined. Based on studies, minerals play an important role in oocyte maturation and subsequent embryo development. Vanadium is one of the minerals, which is ve...

background : chronic kidney disease (ckd) is a complicated kidney problem causing permanent renal failure in progressive stages. the final stage of ckd is called esrd in which most accepted management is hemodialysis (hd). arterio-venus fistula (avf) is the most practical way of making proper access to the blood circulatory system however, maturation of the avf is a challenge, since there are n...

introduction: the purpose of this study was to evaluated the effect of β-mercaptoethanol on resumption of meiosis, in vitro maturation of immature mouse oocytes and resulting embryo development with and without bso (dl-buthionine sulfoximine). material and methods: germinal vasicle (gv) were recovered from 6-8 weeks old nmri ovaries and cultured in maturation medium in memα supplemented with 7....

oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. progesterone (p4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...
