BACKGROUND The Mycobacterium tuberculosis H37Rv and BCG effects on the host cell transcriptional profile consider a main research point. In the present study the transcriptome profiling analysis of RAW264.7 either infected with Mycobacterium tuberculosis H37Rv or BCG have been reported using Solexa/Illumina digital gene expression (DGE). RESULTS The DGE(More)
A cross-sectional survey was conducted during summer 2013 to determine the occurrence of Escherichia coli, fecal coliforms (FCs), E. coli O157:H7, and Salmonella on raw vegetable commodities common to Asian cuisine from 21 vendors or farmers at six farmers' markets in northern California. Based on 242 samples from six commodities (basil, yardlong beans,(More)
The purpose of this study was to investigate the appropriate proportion of Caco-2 and HT29 co-culture in vitro cell models for permeability studies. The results showed that the transepithelial electrical resistance values of 9:1 and 1:0 groups (263 ± 3.61 and 300 ± 7.55) after 21-day culture were >250 Ω cm(2), which were suitable for further experiments.(More)
In the present work, we studied the possible cellular mechanisms of hyperoside isolated from Apocynum venetum leaves in corticosterone-induced neurotoxicity, using PC12 cells as a suitable in vitro model of depression. Cell viability was quantitated by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. The release amount of lactic(More)
Depression is a major psychiatric disorder affecting nearly 21% of the world population and imposes a substantial health burden on society. Although significant progress has been made in depression research, the common molecular mechanism of antidepressants is still far from clearly understood. The neuroprotective effect of antidepressants has been proposed(More)
The calcium-binding residues, Tyr302 and His235, and the sodium-binding residue, Asp194, on the activity of Bacillus licheniformis α-amylase were investigated using site-directed mutagenesis. Tyr302 and His235 were replaced by Asn and Asp, respectively, to produce the mutants Y302N and H235D; Asp194 was replaced by Ala to produce D194A. The mutant amylases(More)
How to target cancer cells with high specificity and kill cancer cells with high efficiency remains an urgent demand for anticancer drugs. Temporin-La, which belongs to the family of temporins, presents antitumor activity against many cancer cell lines. We first used a whole bioinformatic analysis method as a platform to identify new anticancer(More)
A novel virulent phage named JL1 against Escherichia coli O157:H7 was isolated from raw sewage. It was found that JL1 has an icosahedral head and a long flexible non-contractile tail. The complete genome of JL1 is composed of a linear double-stranded DNA of 43,457 base pairs in length, with 54.77 % G+C content and 60 putative open reading frames. Morphology(More)
Mercury ions (Hg(2+)) are one of the most dangerous pollutants. Even at low concentration, it causes serious environmental and health problems. Current methods for the detection of Hg(2+) in environmental samples are tedious and time consuming because they require sophisticated instrumentation and complicated sample pre-treatment processes. In this work, a(More)
Actinobacillus pleuropneumoniae is a causative agent of porcine pleuropneumonia, which is a highly contagious endemic disease of pigs. Adhesion is a critical first step in the infection process. Trimeric autotransporter adhesions (TAAs) have been identified as novel virulence factors; however, little is known on their roles in A. pleuropneumoniae(More)
