Abstract Background Wheat flour maturation affects the aggregation and structural stability of proteins. The number high-molecular-weight glutenin subunits (HMW-GSs) differs in various wheat varieties. effects Dx2 absence on protein characteristics thermal were investigated during 120 days using near-isogenic lines (NILs). Results delayed decreased flours maturation, i.e., maturation-induced in...

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: human chorionic gonadotropin (hcg) has been used as a replacement for the mid-cycle luteinizing hormone (lh) surge for several years. the recent arrival of recombinant dna technology has made recombinant hcg (rhcg) accessible. objective: to assess efficacy of rhcg compared to urinary hcg (uhcg) for triggering of ovulation and induction of final oocyte maturation in assisted reproduc...

Background: in vitro maturation (IVM) of oocytes has increasing potential applications in assisted reproductive technology (ART), during which germinal vesicle (GV) oocytes cultured in vitro to produce mature (MII arrested) ones. Although functional, IVM oocytes have low developmental competence compared to in vivo matured oocytes; possibly because IVM comprises asynchrony between nuclear and c...

background & aim: considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. this study was designed to determine the effect of gundelia tournefortii leaves (gte) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: germinal vasicle (gv) were recovere...

background: in vitro maturation (ivm) of oocytes reduces the costs and averts the side-effects of gonadotropin stimulation for in vitro fertilization (ivf). reliable ivm is an intellectual, scientific and clinical challenge with a number of potential applications. objective: the effect of hcg was evaluated on the timing and regulation of in vitro ovulation for the syrian mice oocytes in the pre...

background: leukemia inhibitory factor (lif) is a 45-56 kda glycoprotein that has an important role in proliferation and embryo implantation. its effect on oocyte maturation and how to exert the function remained to be elucidated. methods: immature mice superovulated with human menopausal gonadotropin and germinal vesicle (gv) oocytes were obtained from ovary 48 hours after. gv oocytes were cul...

background: previous studies have reported the antifertility activities of sulfonamides. this study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. methods: a total of 54 rats were randomly divided into 9 groups (n=6) . group i served as the control and group ii (vehicle) received saline. other groups, iii to ix,...
