Introduction: A favorable endometrium is the essential requirement for implantation. The aim of this study was to determine the predictive value of endometrial power Doppler ultrasonographic parameters in predicting the success of implantation in patients undergoing IVF and ICSI cycles. Methods: Seventy three patients aged<38 years with basal serum FSH level<12 , who had not more than two faile...

As numerical and structural defects in chromosomes are an inevitable consequence of IVF, Pre-implantation genetic diagnosis and screening (PGD/PGS) methods are used for detecting abnormalities in embryos before implantation to the uterus to increase the successful rate of IVF. Pre-implantation genetic diagnosis and screening approaches can be achieved by different techniques such as NGS, CGH an...

assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

PURPOSE To evaluate whether a combination of penetrating keratoplasty (PKP) or pars plana vitrectomy (PPV) and Ahmed glaucoma valve (AGV) implantation affords a level of success similar to that of AGV implantation alone. METHODS Eighteen eyes underwent simultaneous PPV and AGV, 14 eyes with PKP and AGV and 30 eyes with AGV implantation alone were evaluated. Success was defined as attainment o...

Microfluidics holds great potential for the field of assisted reproduction techniques (ART), to provide integrated platforms for combined embryo culture and characterization. The development of mouse embryos is not impaired in a microfluidic format: it proceeds faster during the pre-implantation period (< day 4), and gives similar birth rates. More importantly, single embryo culture is enhanced...

In human in-vitro fertilization (IVF), embryos are routinely transferred to the uterus on either day 2 or day 3 of development, resulting in a 10-15% implantation rate. However, in other mammalian species, the transfer of cleavage stage embryos, which normally reside in the oviduct, to the uterus results in a significantly lower implantation rate compared with blastocysts. It is therefore propo...

BACKGROUND Implantation failure is one of the most important factors limiting success in IVF treatment. The majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. OBJECTIVE The purpose of our trial was to explore whether endometrial injury...

BACKGROUND Despite ACC/AHA guidelines indicating implantable cardioverter defibrillator (ICD) as class I therapy for primary prevention of sudden cardiac death in patients with EF≤35%, ICD utilization rates in real world practice have been low. OBJECTIVE To determine the rate of ICD implantation at a tertiary care academic center and to assess the reasons for under-utilization of the same. ...

BACKGROUND The autonomic nervous system plays a central role in cardiovascular regulation; sympathetic activation occurs during myocardial ischemia. OBJECTIVE To assess the spectral analysis of heart rate variability during stent implantation, comparing the types of stent. METHODS This study assessed 61 patients (mean age, 64.0 years; 35 men) with ischemic heart disease and indication for s...

BACKGROUND Permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVI) remains an issue open for criticism. Aim of this study is to investigate a strategy to reduce PPMI rate after TAVI in general and more specifically after implantation of the LOTUS® prosthesis. METHODS Through our learning curve, we have developed a structured protocol to reduce PPMI rate. T...
