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...

Ion implanters require high energy to improve the light sensitivity of advanced image sensors with deep photodiode structures. Although ion enable implantation, conditions near wafer surface may differ from those in shallow implantation. As implantation increases, dopant ions are implanted deeper into wafer. Consequently, conventional four-point probe tools inappropriate for measuring electrica...

Embryo implantation is a crucial step in mammalian reproduction. However, little is known regarding the physiological roles of microRNAs in the regulation of embryo implantation. Here we show that a minimum uterine expression of miR-181 is essential for the onset of embryo implantation. Both transient and prolonged transgenic expression of miR-181 led to impaired implantation, which can be resc...

BACKGROUND Although embryo implantation is a prerequisite for human reproduction, it remains a poorly understood process. The molecular mechanisms regulating endometrial receptivity and/or embryo implantation are still largely unclear. METHODS Pubmed and Medline literature databases were searched for articles in English published up to December 2013 with relevant keywords including 'endometri...

background: a major hurdle to improved in vitro fertilization (ivf) success rate is defective endometrial receptivity and implantation. various techniques have been advocated to increase implantation while reducing side effects. currently, embryo transfer (et) is performed blindly without direct visualization. as such, we sought to develop a technique utilizing a flexible minihysteroscope with ...

background: implantation remains a limiting step in ivf/icsi. endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after ivf/icsi. objective: the aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on ivf/icsi outcome. materials and methods: four hundred patients undergoing their first ivf/icsi cycle in two ...

Balloon angioplasty of ostial left anterior descending coronary artery (LAD) lesions has been associated with a high rate of acute complications and late restenosis. Recently, coronary stenting has been proposed as an effective treatment modality for ostial LAD lesions. To evaluate the effects of stent design on the development of late restenosis, we retrospectively analyzed the efficacy of slo...

cochlear implantation has become an increasingly common procedure in the rehabilitation of selected cases of profound deafness.' patients should have profound total bilateral sensorineural hearing loss. sound is transformed into small electric currents which stimulate the auditory nerves in the cochlea and generate the hearing sensation. the nucleus cochlear implant is the result of more t...

The endometrium is receptive to embryo implantation only for a short period in each reproductive cycle: development of receptivity requires alterations in endometrial gene expression. Calbindin (CaBP)-d9k and CaBP-d28k are related proteins containing EF hand motifs that have a high affinity for Ca2+. We previously demonstrated that endometrial expression of CaBP-d9k mRNA is highly regulated dur...
