BACKGROUND Neonatal death in full-term infants who suffer from perinatal asphyxia (PA) is a major subject of investigation, since few tools exist to predict patients at risk of ominous outcome. We studied the possibility that urine S100B measurement may identify which PA-affected infants are at risk of early postnatal death. METHODOLOGY/PRINCIPAL FINDINGS In a cross-sectional study between Ja...

Cyclooxygenase-2 (COX-2) enzyme and its inflammatory products such as prostaglandin E2 (PGE2) have been implicated in the pathogenesis of several inflammatory diseases. However their role in diabetic vascular disease is unclear. Advanced glycation end products (AGEs) act via their receptor, RAGE, to play a major role in diabetic complications. In this study, we investigated the effect of AGEs a...

BACKGROUND AND PURPOSE We have previously demonstrated that augmented and prolonged activation of astrocytes detrimentally influences both the subacute and chronic phases of cerebral ischemia. Furthermore, we have suggested that the astrocyte-derived protein S100B may be important in these pathogenic events. However, the causal relationship between S100B and exacerbation of brain damage in vivo...

INTRODUCTION Both recurrent depressive disorders and affective bipolar disorders are characterized by the changes in glial tissue. S100B protein is a calcium-binding molecule, mainly secreted by glial cells, which, depending on its concentration, has a trophic or toxic effect on neuronal cells. In the recent years, due to the postulated glial hypothesis of affective disorders and the ideas conc...

Growing evidence is now available on the use of S100B protein as a valuable marker of brain damage and its role as a neurotrophic factor. Bearing in mind, among different S100B protein properties that are still being investigated, the possibility of measuring this protein in different biological fluids renders it suitable for use in several disciplines. This is the case with perinatal medicine ...

There is growing evidence that genetic abnormalities play an important role in the pathogenesis of Parkinson disease (PD). At least 18 genetic loci and 13 disease-related genes for parkinsonism have been identified. The S100 calcium-binding beta (S100B), which is expressed and secreted by astrocytes, has been found to be associated with PD. To evaluate whether the S100B variants are related to ...

INTRODUCTION Sepsis-associated encephalopathy (SAE) is a diffuse cerebral dysfunction induced by the immuno-inflammatory response to infection. Elevated levels of the brain-specific S100B protein are present in many septic patients and reflect the severity of SAE. Adjunctive treatment with drotrecogin alfa (activated) (DrotAA), the human recombinant form of activated protein C, has been shown t...

Background: S100B Protein is a biomarker that reflects post-trauma brain injury. In traumatic brain injury definite prediction of outcome of the patients is important goal. In this regard our study focuses on the S100B protein value in predicting brain death after head trauma. Methods: This was a cross-sectional study conducted on seventy-two patients (50 male and 22 female) aged 5-80 years (me...

BACKGROUND S100B has been described as a biologic marker of neuronal damage. The purpose of this study was to assess its prognostic value in patients with subarachnoid aneurysmal hemorrhage. METHODS Seventy-four patients (32 men and 42 women; age, 48 +/- 11 yr) admitted within 48 h after subarachnoid hemorrhage onset and treated by surgical clipping or coiling within 2 days after admission we...

In high-density myoblast cultures S100B enhances basic fibroblast growth factor (bFGF) receptor 1 (FGFR1) signaling via binding to bFGF and blocks its canonical receptor, receptor for advanced glycation end-products (RAGE), thereby stimulating proliferation and inhibiting differentiation. Here we show that upon skeletal muscle injury S100B is released from myofibers with maximum release at day ...
