It is still not clear which group of ammonia-oxidizing microorganisms plays the most important roles in nitrification in soils. Change in abundances and community compositions of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) under long-term different nitrogen (N) fertilization rates were investigated in an acidic luvisols soil using(More)
OBJECTIVES To study the cytotoxicity induced by haematoporphyrin monomethyl ether (HMME)-mediated sonodynamic therapy (SDT) on C6 glioma cells. METHODS The potent photosensitizer HMME was used as the sensitizer. Rat C6 glioma cells were incubated with HMME (10 microg/mL) in the dark for 2 h and then subjected to ultrasound treatment at 1.0 MHz and 0.5(More)
This study aimed to explore the correlation between red blood cell (RBC) transfusion volume and patient mortality in massive blood transfusion. A multicenter retrospective study was carried out on 1,601 surgical inpatients who received massive blood transfusion in 20 large comprehensive hospitals in China. According to RBC transfusion volume and duration,(More)
Microbial immobilization/mineralization and mineral fixation/release of ammonium are important for N retention and supply. However, the rates of such processes vary among different fertility soils and fertilization management practices. Three long-term different fertilized soils were used to simulate a range in soil fertility level and incubated with(More)
