abstract aim and background: the purpose of the present study was to investigate the factorial structure, reliability and divergent and convergent validity of the extended life orientation test- persian version (elot-p). methods and materials: first, elot was translated to persian language. then by using the back-translation procedure, the gaps between the translated version and the original ve...

Introduction: Embryonic Stem (ES) cells as pluripotent cells derived from the inner cell mass of blastula can differentiate to neural cells in vitro and this property is valuable in studies of neurogenesis and in the generation of donor cells for transplantation. In this regard, the propose of this research, was the study of the role of two important factors in the development of neural syst...

Vascular endothelial growth factor receptor-2 (VEGFR-2); a cell surface receptor for vascular endothelial growth factors, is a key pharmacological target involved in the cell proliferation/angiogenesis. It has been revealed that VEGFR-2 induces proliferation through activation of the extracellular signal-regulated kinases pathway. In this regard, targeting the VEGFR-2 has been considered as an ...
