Article Synopsis
  • Sitosterolemia is a rare genetic condition leading to abnormal metabolism of plant sterols, resulting in symptoms like skin xanthomas and early heart disease, but brain damage related to the condition hasn't been well-studied.
  • * Researchers examined a family with severe cases of sitosterolemia, where a 66-year-old female patient showed neurological issues including weakness and incontinence, along with brain imaging revealing abnormalities and cholesterol crystal deposits.
  • * Findings suggest that cholesterol deposits in the brain's connective tissues are linked to increased plant sterol levels and two specific gene variants in the family, highlighting the need for more research into the neurological effects of sitosterolemia.*

Coronavirus disease-2019 (COVID-19) first emerged in late 2019 and has since spread worldwide. More than 600 million people have been diagnosed with COVID-19, and over 6 million have died. Vaccination against COVID-19 is one of the best ways to protect humans.

Objective: This study aimed to evaluate the predictive value of quantitative electroencephalography (QEEG) in the outcome of patients with acute ischemic stroke (AIS) who underwent mechanical thrombectomy (MT) and to assess the correlation between clinical outcome and QEEG and CT perfusion (CTP) data.

Methods: Twenty-nine MT patients were included in this prospective study. Continuous electroencephalography (EEG) monitoring was performed, in which delta power, the δ/α ratio (DAR), and the (θ + δ)/(α + β) ratio (DTABR) were calculated.

Background: GGC repeat expansion in has been recently linked to neuronal intranuclear inclusion disease (NIID) via unknown disease mechanisms. Herein, we explore the genetic origin of the sporadic cases and toxic RNA gain-of-function mechanism in NIID.

Methods: Multiple genetic screenings were performed on NIID individuals and their available family members.

To investigate the frequencies and numbers of invariant natural killer T (iNKT) cells and γδT cells in the peripheral blood of patients with the Parkinson's disease (PD), and to examine their association with the PD severity. Peripheral blood samples from 47 PD patients (PD group) and 47 age-matched healthy control subjects (HC group) were collected. The frequencies and the absolute cell numbers were analyzed by flow cytometry.

Background: Multiple sclerosis is a demyelinating and autoimmune disease and its immune response is not fully elucidated. This study was conducted to examine the pathological changes and B cell subsets in experimental autoimmune encephalomyelitis (EAE) mice, and analyze the expression of triosephosphate isomerase (TPI) and GADPH to define the role of B cell subsets in the disease.

Results: Female C57BL/6 mice were randomly divided into EAE group (n = 18) and control (n = 18).

Background: Lots of previous reports have suggested a potential association of atopic dermatitis (AD) with stroke and myocardial infarction (MI). However, the result is still controversial, Consequently, we conducted this meta-analysis to estimate the relationship of AD with Stroke and MI.

Methods: PubMed, Embase, and Web of Science databases were searched from inception to June 2018.

To determine whether glycated hemoglobin and mean arterial pressure (MAP) during thrombolysis are prognostic factors of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) for acute ischemic stroke (AIS).A total of 125 AIS patients, who received rt-PA intravenous thrombolysis in our hospital, were included into the present study, and divided into good prognosis group and poor prognosis group. Univariate and multivariate logistic regression analyses were used to determine the prognostic factors of AIS treated by rt-PA thrombolysis, Spearman correlation analysis was used to analyze the correlation of the accumulated cigarette consumption in the smoking subgroup and glycated hemoglobin in the diabetic subgroup with the prognosis after intravenous thrombolysis and the symptomatic intracranial hemorrhage (sICH).

Background: The pathogenesis of Parkinson's disease (PD) is complex; it includes mitochondrial dysfunction, oxidative stress, and neuroinflammation. Notably, Toll-like receptors (TLRs) may activate inflammatory or anti-inflammatory responses in Parkinson's disease. Vinpocetine has been tested as an anti-inflammatory in both animal and in vitro research.

Objective: This study aims to observe the pathological changes of the brain and spinal cord in an experimental allergic encephalitis (EAE) mice model in the early onset, peak and remission periods of the disease, to detect the changes in the T-cell subsets and cytokine levels, to analyze the types of immune response and related principles in the different stages of the disease.

Methods: C57BL/6 mice were randomly divided into two groups: the EAE group (n = 18) and the control group (n = 18). C57BL/6 mice were immunized with myelin oligodendrocyte glycoprotein (MOG) 35-55 polypeptide/complete Freund's adjuvant (CFA) to establish the EAE mouse model.

Background: Development of Parkinson's disease (PD) is attributed to both genetic and environmental factors. Furthermore,GAPDH may play a key role in the development of neurodegenerative disease. Examination of genetic polymorphism in patients with sporadic PD will help uncover the mechanisms of PD pathogenesis and provide new insights into the treatment of PD.

Bone marrow mesenchymal stem cells (BMSCs) are mainly administered via three routes: intra-arterial, intravenous and intracerebral. It has been reported that BMSC administration via each route ameliorates the functional deficits after cerebral ischemia. However, there have been no comparisons of the therapeutic benefits of BMSC administration through different delivery routes.

Baló's concentric sclerosis (BCS) is a rare demyelinating disorder usually considered a variant of multiple sclerosis (MS). However, its pathogenesis and its correlation with MS remains unclear and controversial. This report presents seven Hans Chinese subjects diagnosed as BCS on the basis of the pathognomonic MR (magnetic resonance) findings.

Objective: To examine the correlation between multiple sclerosis (MS) in Chinese Southern Han population and the polymorphism of HLA-DRB1 and -DPB1 alleles, and compare it to the reports of Western, Japanese and Northern Chinese populations.

Methods: The HLA-DRB1 and -DPB1 alleles of 26 patients with conventional MS (C-MS), 13 patients with optic-spinal form of MS (OS-MS), and 50 normal controls were determined by sequence-based typing (SBT) method. The frequency of the HLA alleles was compared between the 2 MS subtypes and the MS subtypes and the controls by chi(2) or Fisher exact probability test.
