MicroRNA target gene prediction of ischemic stroke by using variational Bayesian inference for Gauss mixture model.

MicroRNAs (miRNAs) as biomarkers of numerous diseases, are a novel group of single-stranded, non-coding small RNA molecules, which can regulate the gene expression and transcription or translation of target genes. Therefore, accurately identifying miRNAs and predicting their potential target genes correlated with ischemic stroke contribute to quick understanding and diagnosis of the pathogenesis of ischemic stroke. In order to identify the targets of miRNAs, the differential expression and expression profiling of mRNAs in genome are integrated by using the Gene Expression Omnibus (GEO) database and limma package.

Effect of Melilotus officinalis extract on the apoptosis of brain tissues by altering cerebral thrombosis and inflammatory mediators in acute cerebral ischemia.

Present investigation evaluates the protective effect of Melilotus officinalis (MO) extract on the brain tissues in acute cerebral ischemia. Acute cerebral ischemia was induced by occlusion of carotid artery and rats with cerebral ischemia were treated with MO (100, 250 & 500mg/kg) for the duration of three days. Cerebral ischemia was confirmed by estimating infract volume and neurological deficit score.
