background and aim: age implantation is one of the effective factors on speech production outcomes in cochlear implanted (ci) children. the purpose of this study is to determine the role of age implantation on formant frequencies and production of three persian vowels including /a/, /u/, /i/ in ci children. methods: sixty nine congenitally deaf children who received ci were divided into three g...

background: it has been demonstrated that performing a mock embryo transfer (et) significantly improves the pregnancy rate in ivf cycles. the mock et could be performed prior to the stimulation cycle or immediately before real et. the problem of the first procedure is the possibility of variation in the uterine position and or cervico�uterine angle. objective: the purpose of this study was to d...

background: there are some controversial data on application of progesterone and progesterone plus estrogen at luteal phase. objective: to investigate the effects of different luteal support hormones on the alkaline phosphates (alp) activity in the endometrial epithelium and endometrial thickness during superovulation process for obtaining the optimized endometrial receptivity in animal model. ...

background: natural endometrium in frozen-thawed embryo transfer (fet) may have some benefits upon implantation in patients with repeated implantation failure (rif). it might be due to possible differences between natural and stimulated endometrial growth factors and cytokins secretions. objective: the objective of this study was to compare the pregnancy rate of fet on modified natural cycle ve...

PurposeThis study aims to evaluate the fluctuation of serum Lactate Dehydrogenase (LDH) in patients who are post-HeartMate 3 (HM3) Left Ventricular Assist Device (LVAD) implantation and determine if routine monitoring LDH values has changed management patients, outcomes, or detected any pump thrombosis events.MethodsThis is a retrospective cohort reviewing electronic medical records forty-eight...

Successful implantation is the result of reciprocal interactions between the implantation-competent blastocyst and receptive uterus. Although various cellular aspects and molecular pathways of this dialogue have been identified, a comprehensive understanding of the implantation process is still missing. The receptive state of the uterus, which lasts for a limited period, is defined as the time ...

BACKGROUND Complications of intrathecal baclofen (ITB) pump implantation for treatment of pediatric patients with spasticity and dystonia associated with cerebral palsy remain unacceptably high. To address the concern that some patients may have underlying arrested hydrocephalus, which is difficult to detect clinically because of a low baseline level of neurological function, and may contribute...

Phospholipase C beta 1 (PLCβ1) is a downstream effector of G-protein-coupled receptor signalling and holds central roles in reproductive physiology. Mice with a disruption in the Plcβ1 gene are infertile with pleiotropic reproductive defects, the major reproductive block in females being implantation failure. Here, PLCβ1 was demonstrated at the luminal and glandular epithelia throughout the pre...

introduction: in this study human follicular fluid has been used as an enzyme- rich solution to prevent embryo implantation in mice which resulted in reduction of pregnancy rate. materials & methods: 2-6 month nih female mice were used to study the effect of interauterine follicular fluid on the fertility rate. 226 plugged female mice were caged in three groups: control, placebo, and experiment...

Introduction: Literature regarding the different degrees of hearing loss in patients with Cornelia de Lange syndrome (CDLS) reports that half of the affected patients exhibit severe to profound sensorineural hearing loss. We present the first pre-school child with CDLS who underwent cochlear implantation for congenital profound sensorineural hearing loss.   Case Report: A 3-year-old boy with CD...
