This research examines dynamics and change in the Iranian family during the recent half- century especially subsequent to the Islamic revolution in 1979. Developmental positions and changes are discussed and consideration is given to the extent to which family dynamics and change have been influenced by structural changes or ideational forces. We will focus on ideational forces based on a new a...
Background: Diabetes mellitus is a metabolic condition characterized by elevated blood glucose levels secondary to absolute impairment of insulin secretion. Maternal diabetes has been demonstrated to adversely affect pre implantation embryo development and pregnancy outcomes. Emerging evidence has implicated that these effects are associated with compromised oocyte competence. Several developme...
Three amplitude-discrimination experiments within a backward masking task were carried out to study whether young children have a slower rate of perceptual processing than do adults. Rate of processing was defined within an explicit model of perceptual performance that allows the investigator to determine if rate is responsible for developmental differences in auditory discrimination. A develop...
introduction: mouse embryos can successfully be frozen with sucrose and propandiol. however, different developmental stages of mammalian embryos have shown to have various capacities to undergo freeze-thawing procedure. in the present study, the ability of 1,2,4 and 8-ell mouse embryo to tolerate the freeze-thawing procedure was investigated and the effect of this procedure on the further in vi...
introduction: the aim of this study was to investigate the growth and development of mouse two cell embryo on human uterine polarized monolayers. material and methodes: human endometrial tissue was obtained from patients who had undergone total hysterectomy. then, epithelial cells were isolated by collagenase i 0.25% and cultured on either ecm gel coated millipore filter insert (polarized) or p...
Experiment 1 investigated developmental differences at high stimulus rates by using maximum length sequences (MLSs) and cross-correlation techniques to recover auditory evoked brainstem responses (ABRs). Reliable MLS ABRs were recorded in all of the newborns tested at the highest rate presented (minimum interpulse interval = 1.1 msec). Interpreting developmental rate effects from latency and am...
