Previous studies on victimization have either used self-reports of peer-reports, but correspondence between these measures is low, implying that types of victims may exist that differ in convergence between self- and peer-reported victimization. Importantly, the very few studies that do exist on such types were cross-sectional, and did not address ...

Hematopoietic stem cells (HSCs) from umbilical cord blood have been successfully used to treat blood disorders but one major hurdle is the relatively low cell dose available. Double cord blood unit transplantation results in elevated engraftment failure because one unit predominates over the other. Various approaches are thus being undertaken ...

Aluminum (Al) is an environmental neurotoxin that affects cerebral functions and causes health complications. However, the role of Al in arbitrating glia homeostasis and pathophysiology remains obscure. Astrocyte, microglia activation (reactive gliosis), and associated inflammatory events play a decisive role in neurodegeneration and may represent a target for treating neurodegenerative ...
