developmental dysplasia of the hip (ddh) or congenital hip dysplasia (cdh) is the most prevalent developmental childhood hip disorder. it includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. the natural history of neglected ddh in adults is highly variable. the mean age of onset of symptoms is 34.5 years for dysplastic dd...

Background: Growth differentiation factor -9B (GDF-9B) is an oocyte derived growth factor, this protein is essential for development of ovarian follicles and act mainly by binding to its receptor on the surface of granulosa cells. The effect of this factor on the growth of follicles in various developmental stages particularly primordial and primary follicles is unknown. The aim of this study w...

-the cowpea aphid, aphis craccivora koch, is an important pest of robinia pseudoacacia frisia. life table parameters of a. craccivora were determined under natural (16- 33ºc and 32-89% rh, respectively) and laboratory (25 ± 1ºc, rh of 70 ± 5% and a photoperiod of 16:8 h (l: d) conditions. the data were analyzed using the age-stage, two-sex life table theory. each experiment was replicated 45 ti...

Introduction: The morphogenic and histogenetic events of an organ and their time sequencing are basic required information to study factors involved in cells differentiation and evaluating the influence of different agents during the critical period of organ formation. The birds are noted as models in experimental embryologic studies, more than other animals. The present study described the mor...

PURPOSE Accurate description of an individual's communication status is critical in both research and practice. Describing the communication status of individuals with severe intellectual and developmental disabilities is difficult because these individuals often communicate with presymbolic means that may not be readily recognized. Our goal was to design a communication scale and summary score...

Development of wheat (Triticum spp.) is primary driven by temperature, but is also affected by other factors such as vernalization and photoperiod. Crop growth and development are often described in terms of calendar days. However, determining the development in terms of thermal time or physiological time is more accurate because it is an accumulation of the caloric energy needed for the o...

Increased understanding of developmental disorders of the brain has shown that genetic mutations, environmental toxins and biological insults typically act during developmental windows of susceptibility. Through analysis of developmental time-course gene expression data derived from human pluripotent stem cells, with disease association, pathway, and protein interaction databases, we identify w...
