OBJECTIVE Left-ventricular assist device (LVAD) implantation complicated by early right ventricle (RV) failure has a poor prognosis. This study details our center's experience with veno-arterial extracorporeal membrane oxygenation (ECMO) as perioperative RV support in patients with preoperative biventricular failure undergoing LVAD implantation. METHODS Ten patients, who underwent LVAD implan...

Left ventricular assist devices (LVAD), currently used in treatment of terminal heart failure, are working on principle of rotary pump, which generates continuous blood flow. Non-pulsatile flow is supposed to expose endothelial cells to high stress and potential damage. Therefore, we investigated longitudinal changes in concentration of circulating endothelial microparticles (EMP) as a possible...

background: despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (g-csf) improves implantation in infertile women. objective: to assess the g-csf effects on ivf outcomes in women with normal endometrial thickness. materials and methods : in this...

We report a very low birthweight infant with congenital complete atrioventricular block (CCAVB) who underwent delayed implantation of a permanent pacemaker without temporary pacing. The female infant was born at 30 weeks gestation and weighed 1422 g. After birth, the infant showed respiratory failure due to pleural effusion and respiratory distress syndrome at birth. The heart rate ranged betwe...

Background: In spite of the great deal of research in assisted reproductive techniques, more than 80% of transferred embryos by IVF/ICSI methods fail to be implanted. The causes for repeated implantation failures (RIF) may be reduced endometrial receptivity or other various uterine pathologies, such as thin endometrium, altered expression of adhesive molecules or immunological factors; whereas ...

Autophagy is ubiquitous in all forms of heart failure and cardioprotective miR-133a is attenuated in human heart failure. Previous reports from heart failure patients undergoing left ventricular assist device (LVAD) implantation demonstrated that autophagy is upregulated in the LV of the failing human heart. Studies in the murine model show that diabetes downregulates miR-133a. However, the rol...

Background: RIF is the most common cause of unsuccessful pregnancy after IVF. Among the various causes of RIF, the role of maternal genetic factors is of great significance. PAI-1 polymorphism is one of the notable polymorphisms in this field. In this study, the relationship between this polymorphism and the recurrent spontaneous abortions and infertility in different populations has been inves...
