background: despite extensive progress in ivf techniques, one of the most difficult problems is the variability in the response to controlled ovarian hyperstimulation (coh). recent studies show the effects of individual genetic variability on coh outcome. objective: to evaluate the correlation between lhβ g1502a polymorphisms in exon 3 of the lh gene and ovarian response to coh. materials and m...

background: intracytoplasmic sperm injection (icsi) is an advanced technique employed in assisted reproductive clinics for treatment of infertile couples. the reproductive endocrinologists try their level best to identify factors that enhance success rate after icsi. objective: to compare estradiol progesterone ratio on ovulation induction day amongst pregnancy outcome groups following icsi. ma...
background: misoprostol, a prostaglandin e1 analogue compared to prostaglandin e2, has the advantage of being inexpensive and stable at room temperature, with its proven efficacy and safety. however studies on the effect of ph on the efficacy of misoprostol have yielded conflicting results. thus its use in the induction of labour in patients with premature rupture of membrane requires further i...
background: different protocols are used for controlled ovarian hyper stimulation (coh), but the optimal method has not yet been determined. objective: the aim of this study was to compare the outcome of controlled ovarian stimulation (cos) using clomiphen citrate (cc) plus hmg versus cc plus rfsh in intra uterine insemination cycles (iui). materials and methods: 144 women with unexplained or m...
introduction: the aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. methods: in order to produce embryoid bodies, es cells line royan b1 were grown in suspension in the absence of lif for 4 days. ebs were divided into 4 groups. ebs in group 1 & 2 were further cultured i...
objective(s): study of non-coding rnas is considerable to elucidate principal biological questions or design new therapeutic strategies. mirnas are a group of non-coding rnas that their functions in pi3k/akt signaling and apoptosis pathways after t cell activation is not entirely clear. herein, mirnas expression and their putative targets in the mentioned pathways were studied in the activated ...
in this paper, a new approach is proposed for the optimum design of single-phase induction motor. by using the classical design equations and the evolutionary algorithms such as genetic algorithms (ga), particle swarm optimization (pso) and modified particle swarm optimization (mpso), a single phase induction motor (spim) was designed with the maximum efficiency. the finite element method (fem)...
the effect of lh and gnrh analogues on induction of ovulation in bactrian camel (camelus bactrianus)
ovarian follicle response and corpus luteum formation following induction of ovulation using gonadotropin-releasing hormone (gnrh) analogues and luteinizing hormone (lh) in bactrian camel were characterized. bactrian camels with a mature follicle (13-19.6 mm) received: 1) natural porcine lh (25 mg, iv, n = 4), 2) buserelin (20 μg, iv, n = 4) and 3) alarelin (25 μg, im, n = 4). daily ultrasonogr...
in this study, an electrostatic sprayer which had been previously designed and constructed was evaluated in order to quantify the charging of droplets. liquid atomization was achieved by using an ultrasonic nozzle. the nozzle maximum flow rate was 25 milliliters per minute and vibration frequency was about 30 khz. the induction method was used for charging the output droplets. all experiments w...
