Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction-the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of in...

Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...

conclusions pet/ct can provide diagnosis and more accurate staging, location of tumor with its capability in providing the anatomical and physiological information synchronizes. therefore pet/ct plays an important role in oncology. objectives in this paper, we evaluate application of pet/ct for improve oncologic imaging. methods the papers were searched in pubmed and scopus databases with the r...

background disability is a relatively common problem in children. the pattern of admission in these children and their common infections may differ from other children because of their special disabilities. objectives we aimed to determine common infectious diseases resulting in admission of these children to our hospital. patients and methods between september 2006 and september 2007, 60 disab...

The human amniotic membrane known as the innermost single epithelial-covered layer provides many applications such as applicable anti-inflammatory and anti-cancer effects. These immunomodulatory effects belongs to the epithelial cells, a type of epiblast-derived fetal stem cells which currently used for regenerative medicine and transplantation. These cells are collected by author-prepared faci...

Welcome to Development’s special issue on stem cells and regeneration. Developmental biology as a field is undergoing profound transformations. The sequencing of genomes has allowed us to move away from single-gene studies and to focus on a more global understanding of the gene regulatory networks underlying development. Modern imaging techniques now allow the precise quantification of developm...
