introduction: the aim of this study was to evaluate the effect of human sperm mtt viability assay on outcome of intracytoplasmic sperm injection. mtt is a tetrazolium salt, routinely used for cell proliferation and cytotoxicity assays. materials and methods: 50μl of processed semen was treated with mtt solution, while the remaining used as the control. meanwhile, 109 donated human oocytes (meta...
Flowering plants (angiosperms) are the most prevalent and evolutionarily advanced group of plants. Success of these plants is owed to several unique evolutionary adaptations that aid in reproduction: the flower, the closed carpel, double fertilization, and the ultimate products of fertilization, seeds enclosed in the fruit. Angiosperms exhibit a vast array of reproductive strategies, including ...
background: human menopausal gonadotropin (hmg) has contributed many improvements to human assisted reproduction. however, effects of hmg on oocyte development and clinical results remain controversial. objective: this study was conducted to investigate the effects of hmg on the zona pellucida of oocytes, as well as clinical results in superovulation treatment. materials and methods: this retro...
Background: Enzymatic and histological change in the testicular cells of rats treated orally, intraperitoneally and intradermally for 45 days with Gibberellic acid (GBA) in independent studies is reported. This study was conducted to evaluate in vitro fertilization (IVF) rate and preimplantation embryonic development in GBA treated adult male rats. Materials and Methods: Thirty six adult male W...
Follicular development, ovulation, fertilization and fetal development in tenrecs (Tenrec ecaudatus)
Religious tourism, as one of the ways of development, cultural exchange and social interaction between nations can have many benefits for any society today. Enjoying indigenous cultures and local religious ethics is an important factor in attracting tourists. The city of Khorramabad has special religious ethics, such as the celebration of gellmalli in the Ashura Day and the chehell manbarr in T...
Fruit and seed formation in plants is normally initiated after pollination and fertilization, and, in the absence of fertilization, flowers senesce. In the Arabidopsis thaliana mutant fruit without fertilization, a mutation in AUXIN RESPONSE FACTOR8 (ARF8) results in the uncoupling of fruit development from pollination and fertilization and gives rise to seedless (parthenocarpic) fruit. Parthen...
Abstract: The object of this research is development of memory assessment system, using Event Related Potentials. Our approach is using ERPs recorded on Fz, Cz and Pz electrodes. Subjects made old/new recognition judgments on new unstudied unmeaning pictures and old pictures which had been presented at study phase. Features related with memory activity in time-frequency domain were used to achi...
