Spatial navigation is a crucial ability for living. Previous animal studies have shown that the S100B gene is causally related to spatial navigation performance in mice. However, the genetic factors influencing human navigation and its neural substrates remain unclear. Here, we provided the first evidence that the S100B gene modulates neural processing of navigationally relevant scenes in human...

Both glial fibrillary acidic protein (GFAP) and S100B have been used as markers of astroglial plasticity, particularly in brain injury; however, they do not necessarily change in the same time frame or direction. Herein, we induced a Parkinson's disease (PD) model via a 6-OHDA intrastriatal injection in rats and investigated the changes in GFAP and S100B using ELISA in the substantia nigra (SN)...

recently, extensive efforts have been made to understand the rate of energy expenditure and the weight gain associated with atypical antipsychotic treatment, including identification of markers of obesity risk. in recent years, leptin, an adipocyte hormone, has gained significant interest in psychiatric disorders. s100b has been considered as a surrogate marker for astrocyte-specific damage in ...

BACKGROUND Intrauterine growth restriction (IUGR) is associated with perinatal mortality and with neurologic damage from intraventricular hemorrhage (IVH). We investigated whether S100B, a neural protein found in high concentrations after cell injury in the nervous system, is increased in serum of women whose pregnancies are complicated by IUGR and whose newborns develop IVH. We also explored t...

BACKGROUND S100B (S100beta) is a member of the S100 family of small calcium-binding proteins: members of this family contain two helix-loop-helix calcium-binding motifs and interact with a wide range of proteins involved mainly in the cytoskeleton and cell proliferation. S100B is a neurite-extension factor and levels of S100B are elevated in the brains of patients with Alzheimer's disease or Do...

The acknowledgement of risks for traumatic brain injury in American football players has prompted studies for sideline concussion diagnosis and testing for neurological deficits. While concussions are recognized etiological factors for a spectrum of neurological sequelae, the consequences of sub-concussive events are unclear. We tested the hypothesis that blood-brain barrier disruption (BBBD) a...

S100B, a calcium-dependent protein produced by astroglial cells in the central nervous system (CNS) and by chondrocytes, functions as both a neurotrophin and neurotoxin. It has a half-life in the systemic circulation of approximately six hours. We examined whether serum levels of S100B would be predictive of intracranial injury (ICI) in children, as detected by cranial computed tomography (CT),...

Purpose: S100B is member of a multigenic family of Ca2þ-binding proteins, which is overexpressed by gliomas. Recently, we showed that low concentrations of S100B attenuatedmicroglia activation through the induction of Stat3. We hypothesized that overexpression of S100B in gliomas could promote tumor growth by modulating the activity of tumor-associated macrophages (TAM). Experimental Design:We ...

In this work we report on an electrochemical biosensor for the determination of the S100B protein. The His-tagged VC1 domains of Receptors for Advanced Glycation End (RAGE) products used as analytically active molecules were covalently immobilized on a monolayer of a thiol derivative of pentetic acid (DPTA) complex with Cu(II) deposited on a gold electrode surface. The recognition processes bet...

S100B is a calcium-binding protein secreted in central nervous system from astrocytes and other glia cells. High blood S100B levels have been linked to brain damage and psychiatric disorders. S100B levels have been reported to be higher in schizophrenics than healthy controls. To quantify the relationship between S100B blood levels and schizophrenia a systematic literature review of case-contro...
