angiogenin sepsis

Background: tRNA-derived small RNAs (tsRNAs) as a novel non-coding RNA have been studied in many cardiovascular diseases, but the relationship between tsRNAs and septic cardiomyopathy has not been investigated. We sought to analyze changes of the expression profile of tsRNAs in septic cardiomyopathy and reveal an important role for tsRNAs. Methods: We constructed a sepsis model by cecal ligation and puncture (CLP) in mice, and microarray analysis was used to find differentially expressed tsRNAs. Quantitative real-time PCR was used to verify the expression of tsRNAs and the interference effect of angiogenin (ANG), a key nuclease producing tsRNAs...

Standard renal replacement therapy in acute renal failure (ARF) and end-stage renal disease (ESRD) is based on membrane technology. The transition from natural cellulosic membranes to synthetic membranes has not been associated with improvement in mortality rates. Modifications of dialysis with continuous arteriovenous hemofiltration and hemodiafiltration to remove middle molecular weight toxins, low molecular weight proteins and peptides (LMWP) and cytokines involved in inflammation appear to have reached their limits...

Renal replacement therapy in acute renal failure (ARF) and chronic renal failure (end-stage renal disease; ESRD) has been based on the use of modifications of dialysis (continuous arteriovenous hemofiltration and hemodiafiltration) to remove middle-molecular-weight toxins, consisting of low-molecular-weight proteins and peptides (LMWP) and cytokines involved in inflammation. High-flux dialyzers are not efficient at removing LMWP, and for this reason, sorbents have been studied to augment or replace dialysis...
