A total of 5608 clinical isolates of Gram-positive bacteria were collected from 12 teaching hospitals across China from 2005 to 2010. The minimum inhibitory concentrations (MICs) of 19 antimicrobial agents were determined by the agar dilution method at the central laboratory. Overall, the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and(More)
Adult community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and methicillin-susceptible S. aureus (CA-MSSA) skin and soft tissue infection (SSTI) in China is not well described. A prospective cohort of adults with SSTI was established between January 2009 and August 2010 at 4 hospitals in Beijing. Susceptibility testing and molecular(More)
Oxygen concentration is essential for appropriate metabolism. Hypoxia can exert a significant impact on physiological alteration of the cell and organism. Tibetan Chicken (Gallus gallus) is a Chinese indigenous breed inhabiting in Tibetan areas, which is also a chicken breed living at high altitude for the longest time in the world. It has developed an(More)
The prevalence of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) among 1,012 vancomycin-susceptible methicillin (meticillin)-resistant S. aureus isolates collected from 14 cities in China from 2005 to 2007 was 13 to 16%, as determined by a combination of (i) measurement by the modified population analysis profile-area under the curve(More)
Ceftazidime-avibactam, aztreonam-avibactam, and comparators were tested by reference broth microdilution against 372 nonrepetitive Gram-negative bacilli (346 unselected plus 26 selected meropenem-nonsusceptible Enterobacteriaceae isolates) collected from 11 teaching hospitals in China in 2011 and 2012. Meropenem-nonsusceptible isolates produced(More)
Interspecies cloning might be used as an effective method to conserve endangered species and to support the study of nuclear-cytoplasm interaction. In this study, we describe the development of takin-bovine embryos in vitro produced by fusing takin ear fibroblasts with enucleated bovine oocytes and examine the fate of mitochondrial DNA in these embryos. We(More)
Hypervirulent Klebsiella pneumoniae (hvKP) is traditionally defined by hypermucoviscosity, but data based on genetic background are limited. Antimicrobial-resistant hvKP has been increasingly reported but has not yet been systematically studied. K. pneumoniae isolates from bloodstream infections, hospital-acquired pneumonia, and intra-abdominal infections(More)
Epigallocatechin-3-gallate (EGCG) is credited with the majority of the health benefits associated with green tea consumption. It has a high economic and medicinal value. The feasibility of using different variable selection approaches in Fourier transform near-infrared (FT-NIR) spectroscopy for a rapid and conclusive quantitative determination of EGCG in(More)
Cloning by somatic nuclear transfer is an inefficient process in which some of the cloned animals die shortly after birth and display organ abnormalities. In an effort to determine the possible genetic causes of neonatal death and organ abnormalities, we used real-time quantitative reverse transcription-polymerase chain reaction to examine expression(More)
