Marginal sea methane seep sediments sustain highly productive chemosynthetic ecosystems and are hotspots of intense biogeochemical cycling. Rich methane supply stimulates rapid microbial consumption of oxygen; these systems are thus usually hypoxic to anoxic. This and reported evidence for resident nitrogen fixation suggest the presence of an anaerobic(More)
The objective of this study is to identify the genetic defects in a Chinese family with autosomal dominant familial neurohypophyseal diabetes insipidus. Complete physical examination, fluid deprivation, and DDAVP tests were performed in three affected and three healthy members of the family. Genomic DNA was extracted from leukocytes of venous blood of these(More)
The purpose of this article is to study the effect of positive antisperm antibody (AsAb) in seminal plasma on acrosomal enzyme activity, nitric oxide synthase (NOS) activity, and superxide dismutase (SOD) activity of spermatozoa. A total of 40 infertility patients with positive AsAb in seminal plasma were selected as experimental group, and 40 fertile males(More)
The purpose of this study was to explore whether the time from pelvic and abdominal nonurological surgery-induced iatrogenic ureteral injuries to repair associates with outcomes. We retrospectively reviewed 81 cases of pelvic and abdominal nonurological surgery-induced iatrogenic ureteral injuries occurring in 78 patients treated at our hospital from(More)
B23, a multifunctional nucleolar protein, is overexpressed in numerous cancers and is associated with tumorigenesis. However, the clinical significance and potential role of B23 in bladder urothelial carcinoma remains to be elucidated. The present study observed that the mRNA and protein expression levels of B23 were increased in bladder cancer cells and(More)
Gastrointestinal surgery-associated anastomotic leaks and luminal perforations can be life-threatening events with high mortality and morbidity rates. In order to get a favorable outcome, early diagnosis and prompt therapy are necessary. In these conditions, the ‘gold standard’ approach to treatment in the past was surgery. However, surgical procedures are(More)
