Background And Purpose: MicroRNAs have recently been shown to regulate the downstream bioprocesses of intracerebral hemorrhage. The aim of this study was to investigate whether miRNAs can be used as biomarkers to predict secondary hematoma enlargement (HE) in patients with ICH.
Methods: Consecutively, 79 ICH patients admitted within 6 h of symptom onset and 30 healthy individuals were enrolled in this study. Whole-genome miRNA expression profiles were generated in 32 patients (HE/non-HE: 14/18). Representative differentially expressed miRNAs were measured in all cases (HE/non-HE: 30/49) and normal controls (n = 30) by real-time PCR.
Results: Thirty miRNAs showed differential expressions in the plasma samples from patients with HE as compared with the non-HE controls. Compared to the hierarchical cluster analysis with all probes on microarray, all patients were separated into two main branches with only four exceptions by 30 differentially expressed miRNAs, improving the overall accuracy from 47.62 to 77.78% in the HE and 72.73 to 100% in the non-HE group. Further support vector machine (SVM) test can discriminate the two groups with 100% accuracy with 10 differentially expressed miRNAs.
Conclusions: We demonstrated that multiple miRNAs are differentially expressed in the plasma of ICH patients with or without HE and may serve as circulating biomarkers for predicting HE after ICH.

Winter barley (Hordeum vulgare) production areas in the middle and lower reaches of the Yangtze River are severely threatened by barley yellow mosaic disease, which is caused by Barley yellow mosaic virus and Barley mild mosaic virus. Improving barley disease resistance in breeding programs requires knowledge of genetic loci in germplasm resources. In this study, bulked segregant analysis (BSA) identified a novel major quantitative trait loci (QTL) QRym.

Regulation of protein production in response to physiological signals is achieved through precise control of Eukaryotic Elongation Factor 2 (eEF2), whose distinct translocase function is crucial for cell survival. Phosphorylation of eEF2 at its Thr56 (T56) residue inactivates this function in translation. Using genetically modified paralogue of a colon cancer cell line, HCT116 which carries a point mutation at Ser595-to-Alanine in the eEF2 gene we were able to create a constitutively active form of eEF2.

Previous studies have demonstrated that one dose of psilocybin leads to persisting neural and behavioral changes. The durability of psilocybin's effects suggests that there are likely alterations of gene expression at the transcriptional level.
