objective: the aim of this study was to evaluate and compare the population of natural killer t lymphocyte (nkt) in the uterus and spleen of the hyperstimulated and control mice at the seventh day of pregnancy. materials and methods: the superovulated and control mice were put individually in a cage with a male mouse. in the next morning they were considered for observing the vaginal plag. the...

background: in this study, we aimed to investigate the ability of transvaginal doppler ultrasonography in predicting in vitro fertilization (ivf) outcome in women undergoing this procedure. materials and methods: in this prospective observational study, 65 infertile women underwent ivf procedure in isfahan, during 2013-2014, were studied. the pulsatility index (pi), resistive index (ri) and pea...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

background: decalcified freeze-dried bone allograft (dfdba) may have the potential to enhance bone formation around dental implants. our aim in this study was the evaluation and comparison of two types of dfdba in treatment of dehiscence defects around euroteknika ® implants in dogs.     methods: in this prospective clinical trial animal study, all mandibular premolars of three iranian dogs wer...

background: vitamin d in complex with its receptor by regulating gene expression, endometrium immune response and stimulation of endometrium decidualization can be involved in implantation. so, it seems that the amount of vitamin d in follicular fluids (ff) may have an association with art success. objective: first, we intended to investigate the possible association between levels of follicula...

Central venous occlusion is a risk when using transvenous pacemaker leads, which may complicate repeated lead implantation. This particularly important in young children with small body sizes, who often need an upgrade from single to dual chamber device later life. Furthermore, survival reported be shorter compared adults. Despite this, there are limited data on access patency during implantati...

Certain uterine prostaglandins (PGs) are elevated at implantation sites and are needed to trigger the events of blastocyst implantation that include blastocyst-uterine attachment and stromal decidualization with vascular permeability changes. Several decades of investigations showed that treatment with PG synthesis inhibitors, prior to or during the time of implantation, resulted in either comp...

The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...

Objective(s): To evaluated the effects of melatonin on early embryo competence and the expression rate of the primary implantation receptors (ErbB1 and ErbB4). Materials and Methods: Two-cell mouse embryos were cultured in 3 groups: simple media, melatonin-treated (10-9 M melatonin) and Luzindole-treated (10-9 M luzindole). Then, the rate of ErbB1 and ErbB4 gene and protein expression, the leve...
