Finite element analysis of retrograde superior ramus screw of pubis for the treament of pelvic anterior ring fracture.

Background: Retrograde superior ramus screw of pubis (SRSP) is a new kind of pelvic minimally invasive internal fixation apparatus developed by our team. The purpose of this study was to analyze the biomechanical stability of this new minimally invasive pelvic internal fixation device, and to provide this new device with theoretical basis for clinical application.

Methods: The Tile C1.

Deletion of pcnB affects antibiotic susceptibility in resistant Escherichia coli by reducing copy number of ColE1-family plasmids.

Plasmids play a major role in the spread of antibiotic resistance genes in bacteria. Plasmid copy number (PCN) is often tightly regulated. In plasmids of the ColE1-type, this regulation happens by a negative feedback mechanism using an antisense RNA.

A combination of microwave treatment and covalent binding of gallic acid improves the solubility, emulsification and thermal stability of peanut protein isolate.

This work aimed to investigate the effect of a combination of microwave treatment and covalent binding of gallic acid (GA) on the structural and functional properties of peanut protein isolate (PPI). It was found that PPI exhibited the maximum solubility at microwave power of 480 W, 60 °C for 4 min. The microwave-treated peanut protein isolates (MPPI) had more binding sites than PPI.

Study on the mechanisms of efficient phosphorus recovery by a pilot-scale biofilm sequencing batch reactor under low carbon demand.

To study the mechanism of a novel pilot-scale biofilm sequencing batch reactor (PS-BSBR) for efficient phosphorus recovery under low carbon demand. The phosphate uptake/release performance and carbon source utilization efficiency of PS-BSBR and a typical enhanced biological phosphate removal (EBPR) -AO process were compared, and the detection methods of different phosphorus forms were improved. The results showed that phosphate uptake/release content of PS-BSBR were 3.
