Fecal microbiota transplantation therapy for Parkinson's disease: A preliminary study.

Imbalances in the gut microbiota mediate the progression of neurodegenerative diseases such as Parkinson's disease (PD). Fecal microbiota transplantation (FMT) is currently being explored as a potential therapy for PD. The objective of this study was to assess the efficacy and safety of FMT on PD.

MFN2 ameliorates cell apoptosis in a cellular model of Parkinson's disease induced by rotenone.

A number of studies indicated that apoptosis, a specific type of programmed cell death, contributed to the loss of dopaminergic neurons during progression of Parkinson's disease (PD). Previously, the authors of the present study demonstrated that apoptosis of dopaminergic neurons was mainly achieved via the mitochondria-mediated apoptosis pathway, however, the precise molecular mechanisms remain to be elucidated. The present study aimed to determine whether mitofusin-2 (MFN2), a mitochondrial protein, participated in the apoptosis of dopaminergic neurons in a cellular model of PD induced by rotenone.

AVE0991, a nonpeptide analogue of Ang-(1-7), attenuates aging-related neuroinflammation.

During the aging process, chronic neuroinflammation induced by microglia is detrimental for the brain and contributes to the etiology of several aging-related neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. As a newly identified axis of renin-angiotensin system, ACE2/Ang-(1-7)/MAS1 axis plays a crucial role in modulating inflammatory responses under various pathological conditions. However, its relationship with aging-related neuroinflammation is less studied so far.

Effects of low oxygen dead space ventilation and breath-holding test in evaluating cerebrovascular reactivity: A comparative observation.

Objective: This study aims to explore the application prospect of low oxygen dead space ventilation (LODSV) in evaluating vasomotor reactivity (VMR) by comparison between LODSV and breath-holding test (BHT).

Methods: Outpatient or inpatient patients who underwent transcranial Doppler sonography (TCD) were enrolled into this study. These patients successively underwent BHT and LODSV.

MicroRNA biomarkers of Parkinson's disease in serum exosome-like microvesicles.

Parkinson's disease (PD) is a progressive age-related debilitating motor disorder and the second most common neurodegenerative disease after Alzheimer's disease. In this study, we aimed to investigate the expression of 24 candidate miRNAs in PD and to assess their diagnostic value in patients with PD. We collected serum samples from 109 patients with PD and 40 age- and sex-matched healthy volunteers (control group).

Flunarizine blocks voltage-gated Na(+) and Ca(2+) currents in cultured rat cortical neurons: A possible locus of action in the prevention of migraine.

Although flunarizine (FLN) has been widely used for migraine prophylaxis with clear success, the mechanisms of its actions in migraine prophylaxis are not completely understood. It has been hypothesized that migraine is a channelopathy, and abnormal activities of voltage-gated Na(+) and Ca(2+) channels might represent a potential mechanism of cortical hyperexcitability predisposing to migraine. The aim of the present study was to investigate the effects of FLN on Na(+) and Ca(2+) channels of cultured rat cortical neurons.
