Interaction of α-synuclein with DJ-1 in homodimer and L166P mutant monomer forms in Parkinson's disease: a molecular dynamics study.

Parkinson's disease (PD) is a progressive neurodegenerative disorder that is characterized by the formation of Lewy bodies, which are primarily composed of misfolded α-Synuclein (α-Syn). DJ-1 is a crucial protein involved in the correct folding of α-Syn, and mutations impairing its function are associated with the onset of PD. One such mutation, the L166P substitution in DJ-1, which has been linked to early-onset PD and results in the loss of DJ-1's homodimer structure.

Methods: This ecological study was conducted in 5 provinces of Iran.

Surgical Management of Tuberculosis-related Cerebral Disorders: A Retrospective Single-center Study.

Background: Tuberculosis (TB) remains a significant global health concern, with extrapulmonary manifestations, including central nervous system involvement, posing substantial morbidity and mortality. While medical treatment with anti-TB drugs is the mainstay of therapy, certain TB-related cerebral complications, such as hydrocephalus, abscesses, and large symptomatic tuberculomas, may require surgical intervention. This study aimed to evaluate the outcomes of surgical management in patients with TB-related cerebral disorders.

Metformin and its potential influence on cell fate decision between apoptosis and senescence in cancer, with a special emphasis on glioblastoma.

Despite reaching enormous achievements in therapeutic approaches worldwide, GBM still remains the most incurable malignancy among various cancers. It emphasizes the necessity of adjuvant therapies from the perspectives of both patients and healthcare providers. Therefore, most emerging studies have focused on various complementary and adjuvant therapies.

Safety and potential effects of intrathecal injection of allogeneic human umbilical cord mesenchymal stem cell-derived exosomes in complete subacute spinal cord injury: a first-in-human, single-arm, open-label, phase I clinical trial.

Objective: Neurological and functional impairments are commonly observed in individuals with spinal cord injury (SCI) due to insufficient regeneration of damaged axons. Exosomes play a crucial role in the paracrine effects of mesenchymal stem cells (MSCs) and have emerged as a promising therapeutic approach for SCI. Thus, this study aimed to evaluate the safety and potential effects of intrathecal administration of allogeneic exosomes derived from human umbilical cord MSCs (HUC-MSCs) in patients with complete subacute SCI.

Molecular dynamic simulation reveals the inhibiting impact of Rhein on wild-type and P29S-mutated Rac1.

Ras-related C3 botulinum toxin substrate 1 (Rac1) is a small GTPase belonging to the Rho family. It acts as a binary molecular switch regulating several cellular functions, including cell adhesion and migration. Malfunctions due to the P29S mutation in Rac1 increase the stability of the activated form of Rac1.

Mesenchymal stem cells and their derived exosomes in multiple sclerosis disease: from paper to practice.

Multiple sclerosis (MS) is a chronic neurodegenerative, inflammatory, and demyelinating disease of the central nervous system (CNS). Current medicines are not sufficient to control the inflammation and progressive damage to the CNS that is known in MS. These drawbacks highlight the need for novel treatment options.

Epidemiology of malignant gliomas in Iran: first report of Iranian National Population-based Cancer Registry, 2009-2017.

Objective: Malignant gliomas constitute the most common type of primary malignant brain tumors. Most previous studies have evaluated the epidemiology of malignant gliomas in developed countries. Hence, there is a lack of evidence in this regard from developing countries.

Co-administration of probiotics and vitamin D reduced disease severity and complications in patients with Parkinson's disease: a randomized controlled clinical trial.

Rationale: Probiotics have beneficial effects on the nervous system by modulating the gut-brain axis. Additionally, vitamin D supplementation presents a potential way for ameliorating neuropsychological disorders, particularly in regions with a high prevalence of vitamin D deficiency.

Objectives: The current clinical trial aimed to investigate the role of co-administered supplementation of probiotics and Vitamin D on the different inflammatory aspects of patients with Parkinson's disease.

Efficacy and Safety of Vaccines After Conventional Treatments for Survival of Gliomas: A Systematic Review and Meta-Analysis.

Background: Malignant gliomas are known with poor prognosis and low rate of survival among brain tumors. Resection surgery is followed by chemotherapy and radiotherapy in treatment of gliomas which is known as the conventional treatment. However, this treatment method results in low survival rate.

Olfactory dysfunction in patients with Parkinson's disease: A systematic review and meta-analysis.

Parkinson's disease (PD) is a progressive neuro-degenerative disease and olfactory dysfunction is considered as an important issue in these patients. The prevalence of olfactory dysfunction in patients with PD was reported variously in previous studies. Therefore, we designed this systematic review and meta-analysis to estimate the pooled prevalence of olfactory dysfunction in patients with PD.

COVID-19 in pregnancy: A cross-sectional study on clinical features, disease severity, and health outcome.

Assessing the impact of coronavirus disease 2019 (COVID-19) reveals unique challenges for pregnant women, who experience distinct clinical manifestations and health outcomes compared to their non-pregnant counterparts. We aimed to evaluate the clinical features, disease severity, and health outcomes of COVID-19 in pregnant women and compare them to those of non pregnant women. In this population-based study, we included all women diagnosed with COVID-19 across the province of Tehran during the first two years of the epidemic.

Surgical tool entrapment in a young patient with recurrent lumbar spinal stenosis: a case report.

Lumbar spinal stenosis (LSS) is a prevalent cause of leg and back pain. In the youth, LSS is not common and mainly results from hereditary musculoskeletal disorders. Moreover, spinal fusion is a surgical approach to the treatment of LSS.
