Implantation failure after IVF is one of the factors associated with a reduced chance of pregnancy for some patients. Assisted hatching methodologies are designed to facilitate the embryo's escape from the zona pellucida, and this strategy has been suggested as a means of improving pregnancy rates in patients with previous implantation failure. The aim of this prospective and randomized study w...

OBJECTIVE The benefits of cochlear implantation for children with developmental delays (DD) often are unclear. We compared cognition, adaptive behavior, familial stress, and communication in children with and without DD. STUDY DESIGN Retrospective review. SETTING Two tertiary care pediatric hospitals. PATIENTS Two hundred four children who underwent cochlear implantation assessed before a...

STUDY QUESTION What is the effect of artificial shrinkage by laser-induced collapse before vitrification on the implantation potential after transfer of vitrified-warmed blastocysts? SUMMARY ANSWER The artificial shrinkage by laser-induced collapse did not significantly increase the implantation rate per transferred collapsed blastocyst (37.6%) compared with non-collapsed blastocysts (28.9%) ...

Background: To achieve multiple oocytes for in vitro fertilization, ovulation induction is induced by gonadotropins however, it has several effects on oocytes and embryo quality and endometrium receptivity. The aim of this study was to assess ultrastructural changes of corpus luteum after ovarian induction using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (HCG) during l...

BACKGROUND The aim of this study was to investigate the safety and effectiveness of fan-shaped distribution and coaxial puncture technology for radioactive iodine 125 (125I) seed implantation in treatment of lung cancer patients with lung dysfunction. MATERIAL AND METHODS We enrolled and analyzed 33 lung cancer patients with lung dysfunction diagnosed in our hospital from 2013 to 2014 in this s...

OBJECTIVE Uterine contraction induced by the embryo transfer (ET) process has an adverse effect on embryo implantation. The aim of this study was to determine the effect of oxytocin antagonist supplementation on the day of ET on in vitro fertilization outcomes via a meta-analysis. METHODS We performed a meta-analysis of randomized controlled trials (RCTs). Four online databases (Embase, Medli...

PURPOSE Sacral root neuromodulation is becoming a superior alternative to the standard treatment of idiopathic nonobstructive urinary retention. We report results in 20 successive patients who underwent sacral foramen implantation to restore bladder function. MATERIALS AND METHODS After an initial, thorough baseline assessment 20 patients 19.43 to 55.66 years old with idiopathic nonobstructiv...

Recent reports have demonstrated that erythroid progenitor cells contain and secrete various angiogenic cytokines. Here, the impact of erythroid colony-forming cell (ECFC) implantation on therapeutic angiogenesis was investigated in murine models of hindlimb ischemia. During the in vitro differentiation, vascular endothelial growth factor (VEGF) secretion by ECFCs was observed from day 3 (burst...
