Introduction: The implantation is a complex procedure that involves many molecules. One of these molecules is integrin specially &alphav&beta3 which serves as receptor for components of extra cellular matrix to act as bridging molecules between the blastocyst and the endometrial surface during the implantation process. By blocking &alphav&beta3 interactions, the implantation can be impaired. ...

Introduction: Estrogen, a crucial hormone during pregnancy, acts through two types of receptors. The estrogen receptor alpha and beta (ESR-α and ESR-β) are more abundant and exists in all human reproductive systems. Association of ESR-α and ESR-β genes polymorphisms has been reported in some reproductive problems such as spontaneous abortion, endometriosis-related infertility, and in vitro fert...

Separation by plasma implantation of oxygen (SPIMOX) has been suggested as an economic alternative for separation by implantation of oxygen (SIMOX) to form the silicon-oninsulator (SOI) structure. The chief advantage of SPIMOX is the high throughput and low-cost implanter. The operation regime of implantation for SPIMOX, which uses dc plasma immersion ion implantation (PIII) for the oxygen impl...

Objective(s): NOTCH signaling pathway is well known for its role in cell fate, cell survival, cell differentiation, and apoptosis. Some of the NOTCH signaling genes are critical for endometrial function and implantation in animals and appear to play a similar role in humans. The purpose of the current study was to investigate the potential roles of some main components of the NOTCH family in hu...

Introduction: One of the most common reasons of infertility is un-ovulatory period. Hormone therapy is the most common treatments of this type of infertility. Gonadotropins may exert toxic effects on the molecular organization of uterine surface, such as glycoconjugates. Glycoconjugates are the most important components of the uterine and trophoblast surface playing an important role in embryo ...

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 patients...

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 ...

the main problemswith the use of fossil fuels is the restrictions on their access and the detrimental consequences of their use which causes a threat to human health and quality of life. consequently, the use of other energy sources has become necessary. renewable energy as a permanent and clean energy source is an answer to this problem. one such energy source includes photovoltaic solar energ...

objective(s): progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. it is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. material and methods: adult female nmri mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...
