Objectives: To determine serum levels of brain-derived neurotrophic factor and its polymorphism rs12291063 in schizophrenic patients.
Methods: The case-control study was conducted from January1, 2020, to May 15, 2021, at Dr Abdul Qadeer Khan Institute of Behavioural Sciences, Dow University of Health Sciences, Karachi, and comprised schizophrenia cases aged 14-60 years who were diagnosed using Diagnostic and Statistical Manual of Mental Disorders-V criteria, and healthy controls without any psychiatric illness. Positive and negative syndrome scale score was used to assess disease severity. The genomic deoxyribonucleic acid of the subjects was isolated from peripheral blood, followed by polymerase chain reaction, gel electrophoresis and sequencing of the amplicons. The sequences were analysed using MEGA X software for genotyping. Serum brain-derived neurotrophic factor levels were assessed using enzyme-linked immunosorbent assay. Data was analysed using SPSS 21.
Results: Of the 100 subjects, 50(50%) were cases; 36(72%) males and 14(28%) females (p<0.05) with mean age 34.34±10.32 years. There were 50(50%) controls; 32(64%) males and 18(36%) females (p=0.391) with mean age 30.886±8.88 years. Among the cases, the mean age at schizophrenia diagnosis was 25.14±9.54 years, and there was a significant association with positive family history for psychiatric disorders (p<0.05). Sequencing revealed no T>C substitution. Serum brain-derived neurotrophic factor levels were significantly higher in cases compared to controls (p<0.001). There was a weak negative correlation between brain-derived neurotrophic factor levels and positive and negative syndrome scale score (p<0.05).
Conclusions: Higher brain-derived neurotrophic factor levels were found to be associated with schizophrenia, while no association of rs12291063 T>C was found with schizophrenia.

Drugs generally used in major depressive disorder are considered inappropriate for the more common milder forms. The efficacy of saffron extracts has been demonstrated in mild to moderate depression and in preclinical models of depression. However, evidence of saffron activity on reduced hedonic responsiveness and motivational anhedonia is limited.

Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.
Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.

Misfolding and accumulation of amyloid-β (Aβ) in the brains of patients with Alzheimer's disease (AD) lead to neuronal loss through various mechanisms, including the downregulation of eukaryotic elongation factor 2 (EEF2) protein synthesis signaling. This study investigated the neuroprotective effects of indole and coumarin derivatives on Aβ folding and EEF2 signaling using SH-SY5Y cells expressing Aβ-green fluorescent protein (GFP) folding reporter. Among the tested compounds, two indole (NC009-1, -6) and two coumarin (LM-021, -036) derivatives effectively reduced Aβ misfolding and associated reactive oxygen species (ROS) production.

Brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB) are known to contribute to both protective and pronociceptive processes. However, their contribution to neuropathic pain after spinal cord injury (SCI) needs further investigation. In a recent study utilizing TrkB mice, it was shown that systemic pharmacogenetic inhibition of TrkB signaling with 1NM-PP1 (1NMP) immediately after SCI delayed the onset of pain hypersensitivity, implicating maladaptive TrkB signaling in pain after SCI.

The negative impact of repeated-mild traumatic brain injury (rmTBI) is profoundly seen in circadian-disrupted individuals. The unrelenting inflammation, glial activation, and gut dysbiosis are key neuropathological aberrations in the aftermath of rmTBI. In this study, we examined the impact of chitosan lactate (CL) on circadian disturbance (CD) + rmTBI-generated neurological dysfunctions and its prebiotic response on the gut-brain axis.
