The Features and Regulation of Co-transcriptional Splicing in Arabidopsis.

Precursor mRNA (pre-mRNA) splicing is essential for gene expression in most eukaryotic organisms. Previous studies from mammals, Drosophila, and yeast show that the majority of splicing events occurs co-transcriptionally. In plants, however, the features of co-transcriptional splicing (CTS) and its regulation still remain largely unknown.

Dietary Energy Level Promotes Rumen Microbial Protein Synthesis by Improving the Energy Productivity of the Ruminal Microbiome.

Improving the yield of rumen microbial protein (MCP) has significant importance in the promotion of animal performance and the reduction of protein feed waste. The amount of energy supplied to rumen microorganisms is an important factor affecting the amount of protein nitrogen incorporated into rumen MCP. Substrate-level phosphorylation (SLP) and electron transport phosphorylation (ETP) are two major mechanisms of energy generation within microbial cells.

Protective effect of madecassoside against cognitive impairment induced by D-galactose in mice.

This study was designed to investigate the protective effect of madecassoside from Hydrocotyle sibthorpioides against cognitive impairment induced by D-galactose (D-gal) in mice. The result revealed that treatment with madecassoside significantly reversed D-gal-induced learning and memory impairments, as measured by the Morris water-maze test. Studies on the potential mechanisms of this action showed that madecassoside significantly reduced oxidative stress and suppress inflammatory responses via blocking NF-κB and ERK/p38 MAPK pathways.

Helenalin attenuates alcohol-induced hepatic fibrosis by enhancing ethanol metabolism, inhibiting oxidative stress and suppressing HSC activation.

A compound was isolated from Centipeda minima using bioassay-guided screening. The structure of this compound was elucidated based on its spectral data, and it was identified as helenalin. The hepatoprotective effect of helenalin was evaluated using a liver fibrosis model induced by intragastric administration with alcohol within 24 weeks in rats.

Treatment of tannery wastewater by electrocoagulation.

Treatment of tannery wastewater by electrocoagulation with low cell current (< or = 1A) and soluble electrodes (mild steel electrodes and aluminum electrodes) was studied. Compared with aluminum electrodes, mild steel electrodes were more effective for the removal of sulfide, with a removal efficiency of over 90%. But during the treatment process, black color precipitate typical to iron(II) sulfides was produced.
