The nature of the early interaction between blastocyst and endometrial epithelium is known to be highly specific within individual species. Despite this unique initial interaction, the trophoblast promptly establishes a common theme as invasive cells penetrate the endometrium and colonize its local blood vessels. In all animals with this type of implantation the blastocyst plays a more active r...

Daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. Providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. Window configuration significantly affects the intensity and uniformity of daylight. This paper aims to investigate the effect o...

Background: The fallopian tube serves as optimal environment for the transport of gamets, fertilization and early development of embryo. In this study, the morphological assessment of superovulated mice fallopian tube were investigated at window implantation period. Materials and Methods: Female mice were superovualated then were mated with vasectomized mice; the mice were divided in experiment...

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...

Introduction: The different factors that affect the camera uniformity of Single Photon Emission Computed Tomography (SPECT) technique have been analyzed including peak shift (%) and window width of energy. The effect of peak shift and window width on SPECT image uniformity has been investigated using a point source to perform intrinsic flood images. Methods:</stro...
