Scientific Paper News Report: Pathological Basis and Topological Properties of Structural Brain Networks in Parkinson’s Disease Patients Background and Research Objectives In Parkinson’s disease (PD), α-synuclein spreads between connected brain regions, leading to neuronal loss and brain network disruption. Using diffusion-weighted imaging (DWI), t...
Comprehensive Overview of Mutations in Neurofibromatosis Type 1 Among Iranian Patients Neurofibromatosis type 1 (NF1) is a hereditary disease caused by mutations in the NF1 gene, characterized by almost complete penetrance and high phenotypic variability. This study aims to identify NF1 mutations in Iranian patients using whole-genome exome sequenc...
Astaxanthin Protects Hippocampal Neurons Against Memory Impairment Caused by Vascular Dementia in Rats Background Introduction Vascular Dementia (VAD) is a progressive cognitive disorder caused by cerebrovascular disease leading to cognitive decline. Current research shows that chronic cerebral hypoperfusion (CCH) and insufficient blood supply are ...
Study on the Protective Effects of Medicinal Microorganisms on Parkinson’s Disease Background Introduction Parkinson’s Disease (PD) is a progressive neurodegenerative disorder characterized by the death of dopaminergic neurons in the substantia nigra region of the brain. The aggregation of α-synuclein is a crucial factor in the pathogenesis of Park...
A scientific paper authored by Ricardo Augusto Leoni de Sousa and his research team was published in Volume 26, Issue 31 of the journal “Neuromolecular Medicine” in 2024. The paper is titled “Physical exercise inhibits cognitive impairment and memory loss in aged mice, and enhances pre- and post-synaptic proteins in the hippocampus of young and age...
Gene Variants and Altered Blood mRNA Levels as Risk Factors for Post-Stroke Cognitive Impairment in Indians Research Background Cognitive impairment is a common clinical outcome after stroke, occurring in about 30% of stroke survivors. Research has shown that Brain-Derived Neurotrophic Factor (BDNF) plays an important role in this process, and BDNF...
Alleviating Effect of EI-16004 on Astrocyte-Mediated Neuroinflammation in MPTP-Induced Parkinson’s Disease Model Background Introduction Parkinson’s Disease (PD) is a neurodegenerative disorder primarily affecting the elderly, characterized by tremors, bradykinesia, rigidity, and loss of postural reflexes, mainly due to the loss of dopaminergic neu...
Study on the Circadian Rhythm of Orexin System Genes and Their Impact on Early Alzheimer’s Disease (AD) Pathology Research Background and Objectives Alzheimer’s Disease (AD) is a chronic degenerative disease of the central nervous system, characterized by senile plaques formed by β-amyloid protein (Aβ) aggregation and neurofibrillary tangles formed...
A New Differential Diagnosis Method Based on miRNA Background Introduction Neuromuscular Disorders (NMDs) are a class of chronic diseases that consistently progress to muscle atrophy. Although certain diseases such as Duchenne Muscular Dystrophy (DMD), Becker Muscular Dystrophy (BMD), Congenital Muscular Dystrophy (CMD), Limb-Girdle Muscular Dystro...
Effects of Chronic Hypertension on Mitochondrial Energy Metabolism in the Cerebral Cortex of Normal and Spontaneously Hypertensive Rats Background Introduction Chronic hypertension has destructive structural and functional consequences for cerebral vessels and brain parenchyma. Hypertension impairs cerebrovascular autoregulation (Ferrari & Villa, 2...
