Objective(s): Failed fertilization after intra-cytoplasmic sperm injection (ICSI) is mainly attributed to failed oocyte activation and can be overcome by artificial oocyte activation (AOA). The present study aims to compare in vitro outcomes of ICSI following two different assisted oocyte activation chemical procedures (SrCl2 and Ionomycin) in sibling oocytes of ICSI candidates.Materials and Me...

background: it is not clear whether the latest activation sites in the left ventricle (lv) are matched with infracted regions in patients with ischemic cardiomyopathy (icm). we aimed to investigate whether the latest activation sites in the lv are in agreement with the region of akinesia in patients with icm.   methods: data were analyzed in 106 patients (age = 60.5 ± 12.1 y, male = 88.7%) with...

background: artificial stimulation of mouse oocyte, in the absence of sperm contribution, can induce its parthenogenic activation of oocyte. ultrasound is one of the newest methods for artificial activation of mammal oocytes, and its successful utilization in pig oocyte activation has been recently reported. our objective was to assess the effect of ultrasound on mouse oocyte activation. materi...

the present study aimed at investigating whether vocabulary-learning strategies had any impact on the vocabulary learning of iranian efl learners. the participants of the study were 67 male and female undergraduate university students, majoring in english translation and english literature at islamic azad university, north tehran branch, who were taking “reading comprehension ii” course. in ord...

the performance of olive stone activated carbon (osac) for sorption of cu2+, zn2+ and ni2+ ions was investigated via batch technique. osac materials were prepared under different physially activation conditions. olive stone waste was physically activated with n2 gas and steam gas at 900oc at 3.5h hold time (osac-3) was choice as the best one for cu2+, zn2+ and ni2+ removal. characterization for...

malting is a complex biotechnological process that includes steeping; germination and drying of cereal grains under controlled conditions of temperature and humidity. in this research malting process parameters were predict by modular neural network with different activation function included, logsig-logsig, tanh-tanh, logsigtanh, logsig-identity and tanh-identity. steeping time (x1) and germin...

objective(s): this study aims to determine the effects of ozone therapy on restoring impaired nrf2 activation to ameliorate chronic tubulointerstitial injury in rats with adenine-induced ckd. materials and methods: sprague–dawley rats were fed with 0.75% adenine-containing diet to induce ckd and chronic tubulointerstitial injury. ozone therapy was administered by rectal insufflation. after 4 we...
