STUDY QUESTION What factors are associated with the presence of areas unexposed to the perfusate after whole ovary perfusion? SUMMARY ANSWER Over half the ovaries perfused with the metabolic marker methylthiazolyl blue tetrazolium (MTT) were incompletely stained. Incomplete staining was statistically significantly associated with a small ovarian slice surface area, inexperience of the experim...

In lizards, the eggs are produced within small regions of the ovary known as germinal beds (GBs); previous literature suggests that the number of GBs per ovary may be linked to life-history traits such as clutch size and breeding frequency. In the oviparous montane Australian skink Bassiana duperreyi, females produce a single clutch of 3 to 11 eggs each year. Our histological examination of ova...

Note Choriocarcinoma of the ovary is a highly malignant ovarian tumor which is characterized pathologically by the presence of trophoblastic malignant cells, and biochemically by the production of the pregnancy hormone human chorionic gonadotrophin (hCG) in the absence of an ongoing pregnancy. Choriocarcinoma tends to be invasive and to metastasize early and widely through both the venous and l...

background: dzn (diazinon) is an organophosphate insecticide that had been used in agriculture and for domestic and veterinary use for several years and caused many negative effects on plants and animal species, especially on human. the aim of present study was to evaluate the effects of dzn on mda (malondialdehyde) and gsh (glutathione) levels in female rat reproductive tissue (ovary) and to a...

purpose to determine the prevalence of polycystic ovary syndrome (pcos) in women who exercise regularly. methods all women under age 45 from an industrial company who had past history of exercising more than 6 months enrolled in this cross-sectional study. prevalence of pcos and comparison of bmi between pcos and non-pcos subgroups was done. the diagnosis of pcos was based on the revised 2003 r...

background: the interaction between follicular cells and oocyte leads to a change in gene expression involved in oocyte maturation processes. objective: the purpose of this study was to quantify the expression of more common genes involved in follicular growth and oocyte developmental competence. materials and methods: in this experimental study, the expression of genes was evaluated with qrt-p...

background: bisphenol a (bpa), an environmental pollutant, can generate free radicals which damages the reproductive system. vitamin c is an antioxidant which may prevent the adverse effects of free radicals.objective: the aim was to investigate the effect of vitamin c on the ovary tissue in rats treated with bpa.materials and methods: in this experimental study, 24 female wistar rats (200±20 g...

background: in this study, we evaluated the incidence of apoptosis at the ultrastructural levels and expression of some apoptosis-related genes in vitrified human ovarian tissue just after warming. methods: human ovarian tissue biopsies from 23 women after caesarean section were transported to the laboratory within 2 hours, and then they were cut into small pieces. some pieces were vitrified an...

objective(s): to evaluate the protective effect of erdosteine, an antiapoptotic and antioxidant agent, on torsion–detorsion evoked histopathological changes in experimental ovarian ischemia-reperfusion (ir) injury. materials and methods: eighteen female wistar albino rats were used in control, ir, and ir+edosteine (ir-e) groups, (n=6 in each). the ir-e group received the erdosteine for seven da...
