The ultrastructural analysis of oocytes and ovarian follicles has been used to evaluate the effects of assisted reproductive techniques, such as cryopreservation or in vitro oocyte maturation. It also benefits the understanding of such complex mechanisms that occur during folliculogenesis. From the beginning of primordial follicles growth until oocyte maturation in preovulatory follicles oocyte...

background:   objective: this study was designed to examine the effects of hp on in-vitro maturation of oocytes and cell death in cumulus cells derived from vitrified-warmed mouse ovaries.   materials and methods: preovulatory follicles were harvested from non-vitrified and vitrified-warmed 6-8 week-old female nmri mouse ovaries and randomly assigned to following groups: non-vitrified (control)...

background: dominant lactic acid bacteria (lab) originally isolated from traditional non-dairy fermented foods, may harbor unique characteristics such as probiotic properties. in this research, probiotic potential of dominant lab isolated from pickled garlic was studied. methods: after isolation of dominant lab from pickled garlic produced with apple cider vinegar, the isolate was identified by...

Background: The treatment of choice for hydatidosis as an important zoonotic disease is surgery. Different agents are injected into the cyst to prevent secondary hydatidosis. To avoid the side effects of such protoscolicidal agents, considering the high protoscolicidal effects of the garlic extract, we conducted the present study on protoscolices in limited applicable times and compared the ext...

abstract: introduction & objective: the infertility treatment by using in vitro matured oocyte has many potential applications. it minimizes the risk of ovarian hyper stimulation and is an alternative treatment for women with polycystic ovarian syndrome who may have problems regarding stimulation for ivf. this method may prove important for subjects in need of fertility preservation and also pr...

embryo culture were used to produce inter specific walnut hybrid plants between juglans nigra l. and j. regia l. developed ovaries were collected from j. rejia female flowers which were pollinated with j. nigra pollen grain by high dusting on a mature tree. in order to isolate embryos, exocarps were aseptically removed. isolated embryos from ovules at different developmental stages were transfe...

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