In order to investigate the contamination levels of trace metals, surface water samples were collected from six regions along Yangtze River in Nanjing Section. The concentrations of trace metals (As, B, Ba, Be, Cd, Cr, Cu, Fe, Pb, Li, Mn, Mo, Ni, Sb, Se, Sn, Sr, V and Zn) were determined using inductively coupled plasma-atomic emission spectrometry(More)
PII is an important signal protein for regulation of nitrogen metabolism in bacteria and plants. We constructed a mutant of glnB, encoding PII, in a heterocystous cyanobacterium, Anabaena sp. PCC 7120, with a cre-loxP system. The mutant (MP2alpha) grew more slowly than the wild type under all nitrogen regimens. It excreted a large amount of ammonium when(More)
An outbreak of rabies affected domestic raccoon dogs on an animal farm in Inner Mongolia, China in 2007. A study was conducted to characterize the aetiological agent and clarify the origin of the rabies virus. Brain tissues were obtained from five rabid raccoon dogs. Viral nucleoprotein antigen was detected in the brain tissues and five rabies viruses were(More)
Immunoglobulin heavy chain (IGH) gene-associated translocations occur frequently in different subtypes of B-cell lymphomas. These translocations result in deregulated expression of partner genes and play pivotal roles in the pathogenesis of lymphomas. Molecular characterization of IGH-associated translocation breakpoints has been instrumental in the(More)
In parallel systems, there are two basic ways in which waiting ready tasks can be organized: centralized organization or distributed organization. In a centralized organization, a single central task queue is maintained. In the latter case, each processor has its own private ready queue of tasks. Ideally. a central task queue global to all processors is(More)
Objective: To validate the prognostic value of NCCN-International Prognostic Index (NCCN-IPI) for patients with peripheral T-cell lymphoma (PTCL) treated with CHOP-based chemotherapy. Methods: A retrospective analysis in 162 PTCL patients who were initially diagnosed and treated in Rui Jin Hospital from January 2003 to May 2013 was conducted. Baseline(More)
To exploit multiple processors, a job is usually partitioned into several tasks that can be executed concurrently. These tasks wait for processors in task ready queue(s). There are two basic ways in which waiting ready tasks can be organized: <italic>centralized</italic> organization or <italic>distributed</italic> organization. In a centralized(More)
Effects of three ions, Mn2+, Cu2+ and Zn2+ on biological treatment of pharmaceutical wastewaterby a functional strain Xhhh were investigated. Through orthogonal tests, Cu2+ was determined to be the most important factor influencing Xhhh biodegradation performance. Biodegradation kinetic experiments demonstrated that with Cu+ concentration at about 200 mg(More)
