Background: There always has been a question about the best age for cochlear implantation (CI) in prelingual deaf children. The age factor in the outcome of cochlear implantation in prelingual deaf children has been the subject of many studies. The aim of the present study was to find the effect of age at the time of implantation on hearing threshold of these children. Methods: One hundred and ...

 Abstract Background: The aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (CI) on speech intelligibility. Methods: Aprospective study was undertaken on 47 children in a pediatric tertiary referral center for CI. All children were deaf prelingually and were younger than 8 years of age. They were followed up until 5...

implantation failure is the most frequent cause of pregnancy loss in couples who try to conceive, either in a natural way or using assisted reproductive techniques (art). identify the precise mechanisms of implantation failure can lead to identify couples at risk and also providing appropriate therapeutic options to affected couples. despite the high prevalence of this disorder, a few causing f...

background: integrins are heterodimeric glycoprotein receptors that regulate the interaction of cells with extracellular matrix and may have a critical role in implantation. the aim of this study was to investigate the effect of ovulation induction on the expression of α4, αv, β1, and β3 integrins in mouse blastocyst at the time of implantation. methods: the ovarian stimulated and non-stimulate...

background: pregnancy rate with ivf cycle is almost 22%. many investigations perform to increase this rate in ivf. various factors affect the result of ivf cycles. one of these factors could be uterine contractions that expel transferred embryo. ritodrine is a beta mimetic agent that can block and decrease uterine contractions. objective: the objective of this study was to determine ritodrine e...

clinical studies have shown that in pathological conditions such as endometriosis and reproductive tract infection (male and female) there is an activation status of macrophages that produce large quantities of nitric oxide (no) in addition to other effector molecules. large amounts of no may have embryotoxic roles and produce infertility. this study was designed to evaluate the effect of diffe...

hla-g is a tolerogenic molecule that expresses in cytotrophoblast cells and plays an important role in immune response suppression in maternal decidua. interactions between the extracellular domains of the hla-g protein with cell receptors of the immune system are well-known.this  study  investigated  the  association  between  hla-g  gene  polymorphism  with repeated implantation failure (rif)...
