a study was conducted to investigate the effect of follicular size (small,

the sexual maturation and spawning period of blood cockle in matang mangrove estuary was studied by naked eye and histological observations of the gonads from july 2010 to april 2011. the high spawning period was from november to february. however, at one station where bottom sediment exhibited a severe reduction in potential of −100 mv lower, immature individuals were common. these results sug...

background: the aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. methods: pre-mature mice were primed with pregnant mare stimulating gonadotrophin (pmsg) and germinal vesicle (gv) stage oocytes were obtained 48 h after. the oocytes were cultured in tissue culture medium (...

the use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (ohss) and potential cancer risk. this is also true in high risk women such as those polycystic with ovary (pco) and polycystic ovarian syndrome (pcos). in vitro maturation (ivm) of oocytes was primarily developed to make ivf safe for women with pco and at high risk of o...

conclusions the relationship between calcification of tooth and maturation of cervical bones was significant. this suggested that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator. results all correlation values obtained were statistically significant (p < 0.001). correlations between dental development and skeletal maturity stage due to cv...

background: therapeutic potential of in vitro maturation (ivm) in infertility is growing with great promise. although significant progress is obtained in recent years, existing ivm protocols are far from favorable results. the first aim of this study was to investigate whether two step ivm manner change reactive oxygen species (ros) and total antioxidant capacity (tac) levels. the second aim wa...

objective: dendritic cells (dcs) are the most effective antigen-presenting cells with many applications. however, dcs can be generated in vitro by various methods from bone marrow cells, each with varying pros and cons. thus, we evaluated three different methods to generate dcs from mice bone marrow cells. materials and methods: bm cells from c57bl/6 mice were cultured in the presence of 1000 u...

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...
