Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...

Аbstract. Relevance. The number of women older reproductive age is steadily increasing, and repeated failures Assisted Reproductive Technologies programs during the transfer high-quality embryos indicate possibility disruption embryo implantation processes associated with impaired receptivity functionality endometrium. Morphological, immunological immunohistochemical changes in endometrium fact...

We report a case of recurrent occlusion of laser iridotomy (LI) sites after a Visian ICL (Implantable contact lens version 4, Staar Surgical AG, Nidau, Switzerland) implantation. A 45-year-old woman had bilateral ICL implantation after placement of two peripheral LI sites in each eye to prevent pupillary block. At one month after the operation, severe narrowing or occlusion of four LI sites occ...

BACKGROUND An examination of the alterations in Fibroblast Growth Factor-1 (FGF-1) expression in a group of repeated implantation failure after in vitro fertilization (IVF) patients, when compared to fertile patients. PATIENTS AND METHODS Study group consisted of 24 patients with repeated implantation failure and 29 fertile control patients. Endometrial samples received at the luteal phase we...

Background: Clinical infertility is defined as the inability to become pregnant after 12 months of unprotected intercourse. Worldwide, more than 80 million couples suffer from infertility;the majority of this population are residents of developing countries. In vitro fertilization (IVF) is the most successful of the infertility treatments, and for many people is the last possibility for pregnan...

Abstract Hydrosalpinx is a disease characterized by the obstruction of salpinx, with progressive accumulation in shape fluid-filled sac at distal part tuba uterina, and closed to ovary. Women hydrosalpinges have lower implantation pregnancy rates due combination mechanical chemical factors thought disrupt endometrial environment. Evidence suggests that presence hydrosalpinx reduces rate assiste...

Abstract Study question To evaluate the efficacy of Hyaluronan Enriched Media (HEM) to optimize Reproductive Outcomes in women with Recurrent Implantation Failures (RIF)? Summary answer In RIF, HEM seems offer beneficial and safer reproductive outcomes. What is known already has shown enhance implantation process an embryo in-utero. Efficacy outcomes still not proven. design, size, duration Thi...
