background: implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (ivf/icsi) failure. several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. this study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patient...

Implantation failure is the most frequent cause of pregnancy loss in couples who try to conceive, either in a natural way or using assisted reproductive techniques (ART). Identify the precise mechanisms of implantation failure can lead to identify couples at risk and also providing appropriate therapeutic options to affected couples. Despite the high prevalence of this disorder, a few causing f...

End-stage heart failure is a growing problem associated with high mortality, using conventional medical care.1 Although heart transplantation remains the gold standard therapy for end-stage heart failure, it is a limited resource that is not applicable to a large portion of heart failure patients, particularly the elderly. An alternative strategy for patients who do not meet standard heart tran...

background: unexplained infertility is still a challenging issue as to its causes, appropriate management and treatment. evidence implicates early embryopathy or implantation failure as likely causes. objective: this study aims to investigate the effect of local endometrial injury on pregnancy rate in selected unexplained infertile patients. materials and methods: this was a randomized clinical...

BACKGROUND Advanced systolic heart failure is associated with myocardial and systemic metabolic abnormalities, including low levels of total cholesterol and low-density lipoprotein. Low cholesterol and low-density lipoprotein have been associated with greater mortality in heart failure. Implantation of a left ventricular assist device (LVAD) reverses some of the metabolic derangements of advanc...

BACKGROUND The number of patients with longer follow-up after implantation of an implantable cardioverter-defibrillator is increasing continuously. Defibrillation lead failure is a typical long-term complication. Therefore, the long-term reliability of implantable cardioverter-defibrillator leads has become an increasing concern. The aim of the present study was to assess the annual rate of tra...
