Itemized determination of As, Sb, Bi, Se, and Ge in graphite sample by HG-AFS with high-temperature microwave digestion.

In this paper, we optimized a method for fast and accurate determination of five impurity elements (As, Sb, Bi, Se, and Ge) in graphite samples to overcome the shortcomings of existing methods, such as complicated equipment, cumbersome process, multiple-time preparation, separate determination, and large error in results. Graphite samples were digested with HNO-HSO-HClO-HF in a high-temperature and high-pressure microwave digestion apparatus, and the elements were extracted and determined separately by AFS (atomic fluorescence spectrometry). There is no element loss during the processing and analysis of this method.

The Inflammatory Transcription Factor C/EBPβ Plays a Critical Role in Cardiac Fibroblast Differentiation and a Rat Model of Cardiac Fibrosis Induced by Autoimmune Myocarditis.

The aim of the present study was to investigate the mechanisms of CCAAT/enhancer-binding protein β (C/EBPβ) in cardiac myofibroblast (CMF) differentiation and in a rat model of cardiac fibrosis induced by experimental autoimmune myocarditis (EAM).In vitro studies performed in primary neonatal rat CMF revealed that silencing of C/EBPβ expression (via lentiviral mediated shRNA strategies) was sufficient to reduce C/EBPβ mRNA and protein levels as well as to decrease the expressions of actin cytoskeletal proteins, cofilin, and filamin A (FLNA). TGFβ increased IL-1β, IL-6 and TNF-a production in cardiac fibroblasts (CF), while C/EBPβ knockdown reduced the secretion of these inflammatory mediators.
