Background: The neurotrophic factor, S100B, is released primarily from astrocytes, with serum and CSF levels of S100B reported as altered in schizophrenia. However, many of these reports are contradictory. Here, serum levels of S100B in schizophrenia and influence of age, gender, medication and illness severity were examined.
Methods: Serum S100B levels were measured in patients with schizophrenia treated with clozapine. Lifestyle, metabolic and illness severity parameters were correlated with S100B concentrations.
Results: Data showed raised serum levels of S100B in schizophrenia female patients, but not male patients, compared to controls. Correlation analysis demonstrated a positive association between S100B serum concentrations and BMI.
Conclusions: This study supports previous findings that adipocytes may contribute to S100B serum concentrations in females, in addition to astrocytes. This study also supports the hypothesis that metabolic effects of medication, lifestyle choices and the illness itself, may be contributing factors to altered levels of S100B.

Previous studies have shown that astrocyte activation in the anterior cingulate cortex (ACC), accompanied by upregulation of the astrocyte marker S100 calcium binding protein B (S100B), contributes to comorbid anxiety in chronic inflammatory pain (CIP), but the exact downstream mechanism is still being explored. The receptor for advanced glycation end-products (RAGE) plays an important role in chronic pain and psychosis by recognizing ligands, including S100B. Therefore, we speculate that RAGE may be involved in astrocyte regulation of the comorbidity between CIP and anxiety by recognizing S100B.

High-concentration oxygen inhalation is the primary intervention to prevent perioperative hypoxemia. However, there are concerns that this may induce an imbalance in oxidation‒reduction processes, particularly in pediatric patients with compromised antioxidant defenses. This study aimed to evaluate the impact of varying intraoperative concentrations of oxygen inhalation on oxidative stress in children by analyzing plasma biomarkers, oxygenation indices, and the duration of surgery and oxygen inhalation.

Polycystic ovarian syndrome (PCOS) is a complex endocrine-metabolic disorder, and multiple factors contribute to its pathophysiology. The current study assessed a PCOS-like animal model induced by consuming a high-fat sugar (HFHS) diet and compared the treatment outcome of mitochondrial-targeted antioxidants versus heat therapy. Sixty rats were divided into the following study groups: three control groups (negative and positive for the treatments used), HFHS, hot tub therapy (HTT) treatment, and MitoQ10 treatment (500 µmol/L MitoQ10 in clean drinking water daily, from week fourteen till week twenty-two of the study).

Cerebral Global Ischemia (CGI) is a devastating neurological condition affecting millions globally each year, leading to significant inflammatory responses and long-term consequences, including delayed neuronal death and neurocognitive impairment. Following brain injury, resident microglial cells are activated, triggering pro-inflammatory cytokine expression and altering neuroimmune processes in a sex-dependent manner, particularly within the hippocampus. Coumestrol, a plant estrogen, is promoted as an alternative to post-menopausal hormone therapy due to its various mechanisms that enhance brain health, including its anti-inflammatory effects.

Traumatic brain injuries (TBIs) are a leading cause of mortality and morbidity, particularly in forensic settings where determining the cause of death and timing of injury is critical. Glial fibrillary acidic protein (GFAP), a biomarker specific to astrocytes, has emerged as a valuable tool in post-mortem analyses of TBI. A PRISMA-based literature search included studies examining GFAP in human post-mortem samples such as brain tissue, cerebrospinal fluid (CSF), serum, and urine.
