Objective: To assess the association between brain-derived neurotrophic factor (BDNF) gene Val66Met polymorphism and clinical characteristics of first episode schizophrenia in a Chinese Han population.
Methods: Genotyping of BDNF Val66Met polymorphism was carried out for 135 schizophrenic patients and 483 healthy controls with TaqMan probe technology. The patients' psychotic symptoms were assessed using the positive and negative syndrome scale (PANSS).
Results: A significant difference was found in genotype distribution and allelic frequency of the Val66Met polymorphism between the two groups (P< 0.01). In patients, Met homozygotes had a significantly higher score in anxiety/depression factor, cognitive factor and total score of PANSS than Val carriers.
Conclusion: BDNF gene Val66Met polymorphism is associated with the pathogenesis of schizophrenia. The Met/Met genotype of BDNF Val66Met variant may be a risk factor for symptoms in first episode schizophrenia patients.

Intrusive memories are a key symptom of Post-Traumatic Stress Disorder (PTSD). Brain Derived Neurotrophic Factor (BDNF) has been proposed as a possible mechanism influencing intrusive memories in PTSD given its role in synaptic plasticity and memory consolidation. The BDNF Val66Met polymorphism has been linked PTSD susceptibility and episodic memory disturbances however previous research outcomes have been variable, potentially due to a failure to control for important confounds such as sex, ethnicity, BMI, developmental stage and extent of previous trauma experiences.

Introduction: The polymorphism in the brain-derived neurotrophic factor (BDNF) gene has been linked to antidepressant treatment response in patients with major depressive disorder (MDD), yet findings remain inconclusive. This updated meta-analysis aimed to clarify this association and explore subgroup effects based on antidepressant class and treatment duration.
Methods: A systematic search of PubMed, Web of Science, and Google Scholar was conducted through 27 December 2024.
Microwave radiation is extremely sensitive to the brain and has been shown in animal models to affect memory and learning. Brain-derived neurotrophic factor (BDNF) is essential for neural function and brain development, with many single nucleotide polymorphisms (SNPs) in gene. Several neuropathological disorders have been linked to the BDNF Val66Met variation.

Peripheral nerve injuries affect large numbers of individuals each year, often resulting in long-term disabilities due to impairments in motor and sensory function. With traditional treatment approaches, including surgical repair and rehabilitation, the most common outcome is incomplete recovery. This is compounded by the absence of FDA-approved medications to enhance nerve regeneration.

The aim of this study was to determine the relationship between BDNF and lactate concentration, accounting for genotype and sex, before and after a submaximal graded exercise test in 31 adults (37.5 ± 14.0 years, 54.
