This work aims to investigate the anatomical basis and clinical application value of renal pedicle locating in retroperitoneoscopic nephrectomy. To summarize the anatomical basis of renal pedicle locating through retrospective analysis of 278 cases of retroperitoneoscopic nephrectomy from July 2007 to September 2009, during which renal pedicle was located at about 2-4 cm below the medial arcuate ligament of the diaphragm in the space between the psoas major muscle and inferior vena cava (abdominal aorta) in the anatomical level of space before psoas. The operation of 278 patients was all successfully completed, where renal pedicle was quickly found. It took 3.5±1.3 min to locate the renal pedicle, and 95.6±23.8 min to operate. In retroperitoneoscopic... |

ABSTRACT Anaerobic digestion is important for the management of livestock manure with high ammonia level. Although ammonia effects on anaerobic digestion have been comprehensively studied, the molecular mechanism underlying ammonia inhibition still remains elusive. In this study, based on metatranscriptomic analysis, the transcriptional profile of microbial community in anaerobic digestion under low (1500 mg L-1) and high NH4 + (5000 mg L-1) concentrations, respectively, were revealed. The results showed that high NH4 + concentrations significantly inhibited methane production but facilitated the accumulations of volatile fatty acids. The expression of methanogenic pathway was significantly inhibited by high NH4 + concentration but most of the other... |
