background: vascular access (va) is an important aspect for blood circulatory in hemodialysis (hd). arteriovenous fistula (avf) is a suitable procedure to gain va. maturation of the avf is a status of avf, which can be cannulated for hd. this study aimed to discover the parameters that effectively reduce the duration between va and start of hd, which symbolizes the maturation time (mt).   metho...

Background: Mammalian oocyte undergoes a series of structural nuclear modulations during maturation in order to obtain full competence to support fertilization and early embryonic development. Microtubules are major cytoskeleton components and have pivotal modulators for chromosomal movement, and it has been shown that partial or immature spindle organization may compromise correct ploidy of th...

objective: nutrients and antioxidants in the medium of immature oocyte have a profound effect on maturation, fertilization and development of resulting embryos. in this study the effects of melatonin as an antioxidant agent on maturation, glutathione level and expression of high mobility group box-1 (hmgb1) gene were evaluated in immature oocytes of mice stained with brilliant cresyl blue (bcb)...

in vitro maturation (ivm) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. this review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. the review is based on literature reports and the author’s experience. in ivm cycles,...

objective: currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hcg) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (ivf), but doses that range from 2500- 15000 iu have been used. we intended to determine whether low dose u-hcg was effective for oocyte maturation in ivf/intracytoplasmic sper...

background: the effect of temperature and humidity on the maturation of toxocara cati eggs in an in vitro system was investigated. methods: suspensions of toxocara cati eggs, with 5% formalin/saline or 2.5% formalin/ringer were prepared and maintained at 37 °c under 40% humidity or at 25 °c under 98% humidity for 3 weeks for egg development. results: the suspension sample mixed by 2.5% formalin...
