A comparative analysis of 375 patients with lateral and medial medullary infarction.

Background: Few studies have compared the etiology and clinical features between pure lateral medullary infarction (LMI) and pure medial medullary infarction (MMI).

Methods: All patients included were hospitalized at The First Affiliated Hospital and The Second Affiliated Hospital of Wenzhou Medical University from January 2015 to July 2020. Their risk factors, clinical manifestation, stroke mechanisms and short-term prognosis were analyzed retrospectively.

A homozygous mutation of alanyl-transfer RNA synthetase 2 in a patient of adult-onset leukodystrophy: A case report and literature review.

Introduction: Leukodystrophy is a group of hereditary leukoencephalopathies predominantly affecting the white matter. Multiple genes and mutations have been reported to be associated with this disorder. Identification of pathogenic genes can facilitate diagnosis of leukodystrophy and development of therapeutic strategies.

Meta-analysis of brain iron levels of Parkinson's disease patients determined by postmortem and MRI measurements.

Brain iron levels in patients of Parkinson's disease (PD) are usually measured in postmortem samples or by MRI imaging including R2* and SWI. In this study we performed a meta-analysis to understand PD-associated iron changes in various brain regions, and to evaluate the accuracy of MRI detections comparing with postmortem results. Databases including Medline, Web of Science, CENTRAL and Embase were searched up to 19 November 2015.

Selenotranscriptomic Analyses Identify Signature Selenoproteins in Brain Regions in a Mouse Model of Parkinson's Disease.

Genes of selenoproteome have been increasingly implicated in various aspects of neurobiology and neurological disorders, but remain largely elusive in Parkinson's disease (PD). In this study, we investigated the selenotranscriptome (24 selenoproteins in total) in five brain regions (cerebellum, substantia nigra, cortex, pons and hippocampus) by real time qPCR in a two-phase manner using a mouse model of chronic PD. A wide range of changes in selenotranscriptome was observed in a manner depending on selenoproteins and brain regions.

Paroxetine ameliorates lipopolysaccharide-induced microglia activation via differential regulation of MAPK signaling.

Background: Paroxetine, a selective serotonin reuptake inhibitor for counteracting depression, has been recently suggested as having a role in prevention of dopaminergic neuronal degeneration in substantia nigra, a hallmark of Parkinson's disease (PD). The pathogenesis of this type of neurological disorders often involves the activation of microglia and associated inflammatory processes. Thus in this study we aimed to understand the role of paroxetine in microglia activation and to elucidate the underlying mechanism(s).

CCDC62 variant rs12817488 is associated with the risk of Parkinson's disease in a Han Chinese population.

It has been recently proposed by a genome-wide association study (GWAS) meta-analysis that the CCDC62 variant rs12817488 is a new risk locus associated with Parkinson's disease (PD). In this study, we aimed to investigate the association between rs12817488 and PD in a Chinese cohort. A total of 341 PD patients and 423 matched controls were recruited in Eastern China.

[Effects of chronic hypoxic hypercapnia on spatial learning-memory and expression of NMDAR1 in rats].

Aim: To explore the effect of chronic hypoxic hypercapnia on learning-memory and the possible mechanisms involved.

Methods: Fifty-eight male SD rats were randomly divided into three groups: Normal control group (NC, n=18), 2-week (2HH, n=18), and 4-week hypoxic hypercapnia (4HH, n=20) group. The rats, spatial learning-memory tasks were assessed by the Morris water maze.
