Reduction characteristic of chlorobenzene by a newly isolated Paenarthrobacter ureafaciens LY from a pharmaceutical wastewater treatment plant.

A highly efficient chlorobenzene-degrading strain was isolated from the sludge of a sewage treatment plant associated with a pharmaceutical company. The strain exhibited a similarity of over 99.9% with multiple strains of Paenarthrobacter ureafaciens.

Performance and Microbial Community Analysis of an Electrobiofilm Reactor Enhanced by Ferrous-EDTA.

The biological reduction of ferrous ethylenediaminetetraacetic acid (EDTA-Fe-NO and EDTA-Fe) is an important process in the integrated electrobiofilm reduction method, and it has been regarded as a promising alternative method for removing NO from industrial boiler flue gas. EDTA-Fe-NO and EDTA-Fe are crucial substrates that should be biologically reduced at a high rate. However, they inhibit the reduction processes of one another when these two substrates are presented together, which might limit further promotion of the integrated method.

[Effect of Human Umbilical Cord-derived Mesenchymal Stem Cells on Proliferation and Differentiation of Leukemia Cells].

Objective: To investigate the effect of human umbilical cord-derived mesenchymal stem cells(HUC-MSC) on the proliferation and differentiation of NB4 treated with all-trans retinoid acid (ATRA) and its underlining mechanisms .

Methods: Human umbilical cord mesenchymal stem cells were isolated from umbilical cord of newborns. Co-culture system was established by HUC-MSC and NB4 in vitro.

Phase I evaluation of the safety and pharmacokinetics of a single-dose intravenous injection of a murine monoclonal antibody against Hantaan virus in healthy volunteers.

Anti-Hantaan virus monoclonal antibody (AHM) is a murine monoclonal antibody against Hantaan virus being developed for the treatment of hemorrhagic fever with renal syndrome. The purpose of the present study was to describe the tolerance and pharmacokinetics of an intravenously administered single ascending dose of AHM in Chinese healthy volunteers. Four cohorts of 22 healthy subjects received AHM at 2.
