Risk factors for ischemic stroke in patients with Philadelphia chromosome (Ph)-negative myeloproliferative neoplasms.

Background: Philadelphia chromosome-negative myeloproliferative neoplasms (Ph-negative MPNs) are linked with various complications, notably ischemic stroke. The study aims to identify risk factors for ischemic stroke in Ph-negative MPNs patients.

Methods: Patients were categorized into two groups based on whether they had experienced ischemic stroke.

Pre-administration of BAX-inhibiting peptides decrease the loss of the nigral dopaminergic neurons in rats.

Aims: In this study, we investigated the effects of Bax-inhibiting peptide (Bip)-V5, an anti-apoptosis membrane-permeable peptide, on the 6-hydroxydopamine (6-OHDA) induced Parkinson's disease (PD) model rats.

Materials And Methods: Rats were randomly divided into five groups: Control, 6-OHDA only, Vehicle+6-OHDA, zVAD+6-OHDA, and V5+6-OHDA, that rats were preadministrated with different reagents before 6-OHDA administration.

Key Findings: The result showed that intrastriatal preadministration of Bip-V5 significantly decreased the amphetamine-induced rotation of the 6-OHDA model rats and the loss of the nigral dopaminergic (DA) neurons.

Bone marrow mesenchymal stem cells ameliorate neurological deficits and blood-brain barrier dysfunction after intracerebral hemorrhage in spontaneously hypertensive rats.

Spontaneous intracerebral hemorrhage (ICH) is a common and fatal subtype of stroke, with hypertension the most common cause of this disorder. Bone marrow derived mesenchymal stem cells (BM-MSCs) have been shown to elicit protective properties in stroke models. In the present study, male spontaneously hypertensive rats (SHR) were subjected to ICH by intracerebral injection with autologous blood, Wistar-Kyoto (WKY) rats were employed as control.

Bone marrow stromal cells combined with oxiracetam influences the expression of B-cell lymphoma 2 in rats with ischemic stroke.

This study aimed to investigate the combination effects of bone marrow stromal cells (BMSCs) and oxiracetam for ischemic stroke. Forty Sprague Dawley female rats (220 ± 20 g) were subjected to a 2-hour ischemic middle cerebral artery occlusion (MCAO)-24 hours reperfusion model. The rats were randomly divided into 4 groups.

Stratification of gene coexpression patterns and GO function mining for a RNA-Seq data series.

RNA-Seq is emerging as an increasingly important tool in biological research, and it provides the most direct evidence of the relationship between the physiological state and molecular changes in cells. A large amount of RNA-Seq data across diverse experimental conditions have been generated and deposited in public databases. However, most developed approaches for coexpression analyses focus on the coexpression pattern mining of the transcriptome, thereby ignoring the magnitude of gene differences in one pattern.

T cell CD40LG gene expression and the production of IgG by autologous B cells in systemic lupus erythematosus.

CD40 ligand (CD40LG), encoded on the X chromosome, has been reported to be overexpressed on lupus T cells. Herein, we investigated the effect of DNA demethylation on T cell CD40LG expression and the production of IgG by autologous B cells in lupus. We found normal human T cells transfected with CD40LG induced autologous B cell activation and plasma cell differentiation.

Identification of novel genetic susceptibility loci for Behçet's disease using a genome-wide association study.

Introduction: Behçet's disease is a chronic systemic inflammatory disease that remains incompletely understood. Herein, we perform the first genome-wide association study in Behçet's disease.

Methods: Using DNA pooling technology and the Affymetrix 500K arrays, we identified possible candidate gene associations with Behçet's disease in a cohort of 152 Behçet's disease patients and 172 healthy ethnically matched controls.
