Natural rubber processing is one of the potential agro-industrial sectors for Indonesia, whose role quiteimportant as a foreign exchange earner plantation sub-sector. The production rate 1.6 million tons in2002 or 22% world's total natural has placed Indonesia second largest producingcountry after Thailand. This study aims to determine whether quality blanket sir 10 optimal by using amaturation...

Background: The buffalo (Bubalus bubalis) is the animal with special production characteristics in producing milk and meat has a critical role in rural industry in Iran. The most problem of this specie is its low reproductive output. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on maturation rate of Buffalo oocyte.Materials and Methods: Ovaries were colle...

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

the majority of cancer treatments are invasive. gonadal injuries cause reductions in fertility which results in lack of hope for conception in cancer patients and frustration for their partners. fortunately, current advancements in cryopreservation and transplantation sciences regarding fertility preservation lead to cryostorage of gonads and preservation prior to the onset of chemo- and radiot...

conclusions the present study showed that vitrification using cryotop and freezing medium can damage oocytes by reducing the maturation and fertilization rates in both developmental stages. results vitrification caused a significant reduction in the maturation rate of oocytes. of those that matured, the fertilization rate of vitrified ivm-mii (44.1%) and ov-mii oocytes (50%) was not significant...

validation of predicting fatness methods in the iranian girls with respect to the maturity process could help to identify anthropometric risk factors. this study evaluate the accuracy of four body composition prediction equations in the teenager students in hamadan city .method: the anthropometry profile of 266 adolescent girls (12-16 ys) including ,weight (55.69±10.18 kg),body mass index (21.9...

background: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...

background: in general, 15% of oocytes collected in art cycles are immature. these oocytes may be cryopreserved further for use in in-vitro maturation (ivm) program. objective: the aim of this study was to determine maturation capacity, morphometric parameters and morphology of human immature oocytes in both fresh ivm (fivm) and vitrified-ivm (vivm) oocytes. materials and methods: 93 women who ...

sea cucumbers saponins are triterpenoid glycosides which exert beneficial biomedical effects. this study was performed to assess the effect of saponin extracted from sea cucumber holothuria leucospilota            ( h. leucospilota ) on maturation of mice oocytes and granulosa cells. the germinal vesicles oocytes were collected from 6–8 weeks old naval medical research institute (nmri) mice ova...

background: falciparum malaria is a severe health burden worldwide. antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. malarial hemozoin (hz), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. objective: to determine the immunological impact of hemozoin on the capacity ...
