background: in previous studies, the neuroprotective effect of 17&beta-estradiol; in diffuse traumatic brain injury has been shown. this study used ici 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17&beta-estradiol; in traumatic brain injury is mediated by the estrogen receptors. methods: the ovariectomized rats were divided in...

Background and Objective: The S100B protein has recently been considered as an important marker for predicting severe brain damage; however, there has been very little evidence of increasing this marker in cerebral edema due to metabolic disorders such as diabetes ketoacidosis (DKA). This study was designed and performed to evaluate the prognostic role of S100B protein in predicting brain edema...

Background: Predicting adverse neurovascular complications due to diabetic ketoacidosis (DKA) particularly in children leads to more appropriately management of disease as well as achievement of acceptable patients' survival. Cerebral edema is a life-threatening adverse event following DKA responsible for high mortality rate. Recently, authors have focused introducing new risk assessment tools ...
