The clinical efficacy of a spoligotyping method for discriminating Mycobacterium tuberculosis strains was evaluated. Among the strains other than Beijing or Beijing like family, 30 different spoligotypes out of 39 strains were produced, which included 4 strains not having IS6110 sequence. The oligonucleotide chip-based spoligotyping technique is useful for(More)
The in vitro activities of CG400549, a novel FabI inhibitor, were compared to those of linezolid and commonly used antimicrobials against recent bacterial isolates. CG400549 had an MIC(90) of 0.5 microg/ml for Staphylococcus aureus strains and was more potent than either linezolid or vancomycin.
Histone acetyltransferases (HATs) use acetyl CoA to acetylate target lysine residues within histones and other transcription factors, such as the p53 tumor suppressor, to promote gene activation. HAT enzymes fall into subfamilies with divergence in sequence and substrate preference. Several HAT proteins have been implicated in human cancer. We have(More)
Oligonucleotide chips targeting the bacterial internal transcribed spacer region (ITS) of the 16S-23S rRNA gene, which contains genus- and species-specific regions, were developed and evaluated. Forty-three sequences were designed consisting of 1 universal, 3 Gram stain-specific, 9 genus-specific, and 30 species-specific probes. The specificity of the(More)

In this study, we investigated the inhibitory effects of purpurogallin, a naturally occurring phenol, on the production of lipopolysaccharide (LPS)-induced pro-inflammatory mediators and cytokines in BV2 microglia cells. The cells were pre-treated or not with various concentrations of purpurogallin and then stimulated with 0.5 µg/ml LPS. Cell viability was(More)
The aim of this study was to evaluate the beneficial effects of Schisandrae semen essential oil (SSeo) on apoptosis events and the mechanisms associated with these effects in human leukemia U937 cells. The treatment of U937 cells with SSeo significantly inhibited survival and induced apoptosis. Schisandrae semen essential oil treatment increased the levels(More)
BACKGROUND Sargassum horneri, an edible marine brown alga, is typically distributed along the coastal seas of Korea and Japan. Although several studies have demonstrated the anti-oxidative activity of this alga, the regulatory mechanisms have not yet been defined. The aim of the present study was to examine the cytoprotective effects of S. horneri against(More)
BACKGROUND Pyrazinamide (PZA) is among the first-line drugs for the treatment of tuberculosis. In vitro, it kills semidormant mycobacteria only at low pH. The purpose of this study was to compare PZA resistance with pyrazinamidase (PZase) activity and the genotype to better understand the molecular basis of PZA resistance and to expand the profile of pncA(More)
OBJECTIVES This study was performed to analyse in vitro and in vivo activities of CG400549, a new FabI inhibitor, against clinical isolates of staphylococci. The mode of action of CG400549 and resistance mechanism of Staphylococcus aureus against CG400549 were also investigated by genetic approaches. METHODS In vitro activity of CG400549 was evaluated by(More)
BACKGROUND Four traditional Korean medicinal herbs which act in retarding the aging process, Polygonum multiflorum Thunb., Rehmannia glutinosa (Gaertn) Libosch., Polygala tenuifolia Willd., and Acorus gramineus Soland., were prepared by systematic investigation of Dongeuibogam (Treasured Mirror of Eastern Medicine), published in the early 17th century in(More)
