A novel Gram-positive, rod-shaped, motile, spore-forming, nitrogen-fixing bacterium, designated strain 7188T, was isolated from jujube rhizosphere soil in Beijing, China. The strain grew at 4–40 °C and pH 6–12, with an optimum of 30 °C and pH 7.0, respectively. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain 7188T is a member(More)
In this study, a series of new 5-alkoxy-[1,2,4]triazolo[4,3-a]pyridine derivatives was synthesized and their anticonvulsant activity and neurotoxicity was evaluated with the maximal electroshock and rotarod tests, respectively. The most promising compounds, 3p (5-(4-chlorophenoxy)-[1,2,4]triazolo[4,3-a]pyridine) and 3r(More)
In this study, two phenanthrene-utilizing and high-effective P-accumulating bacteria Y11 and Y4-2 were isolated from sludge samples of Taihu Lake using plate culture and blue-colored colonies methods. Strains Y11 and Y4-2 were identified as Acinetobacter sp. according to the results of morphology, physiology and the phylogenetical analyses of 16S rDNA(More)
OBJECTIVE To investigate the effects of protein tyrosine kinase (PTK), protein tyrosine phosphatase (PTP) and protein kinase C (PKC) on apoptosis and observe the changes of cytosolic calcium ([Ca(2+)]i) of arsenic trioxide (As2O3) treated human leukemia cells NB4 and cortex neurons. METHODS [Ca(2+)]i of NB4 cells and cortex neurons was probed with(More)
OBJECTIVE To investigate the expression of bcl-2 gene and cell apoptosis and cell cycle in bone marrow of chronic myelogenous leukemia (CML). METHODS APAAP assay and in situ hybridization were used for the expression of BCL-2 protein and bcl-2 mRNA in fresh bone marrow samples from 60 cases of CML. Flow cytometry was used to assess the extent of apoptosis(More)
OBJECTIVE To study the effects of constantly slow intravenous arsenic trioxide (As2O3) infusion regimen on decreasing leukocytosis in vivo and in vitro. METHODS Three kinds of leukemia cells, NB4, K562, and acute promyelocytic leukemia (APL) cells, were cultured in the media with constant concentration and varying concentrations of As2O3 respectively for(More)
