A total of 567 lactic acid bacteria (LAB) strains were isolated from the stool samples of longevous people in regions of Hotan, Xinjiang and Bama, Guangxi, China. In order to reduce the number of strains for further examinations, 36 isolates were screened out for further examination whilst the other strains, which had lower probiotic properties, were not(More)
This paper put forward a deconvolution-based method for designing and optimizing tanshinone IIA sustained-release pellets (TA-SRPs) with improved efficacy in the treatment of variant angina. TA-SRPs were prepared by coating TA ternary solid dispersion immediate-release pellets (TA-tSD-IRPs) with the blends of polyvinyl acetate (PVAc) and polyvinyl(More)
Bacterial communities in rhizosphere soil of healthy and diseased cotton (infected by the pathogenic fungus Verticillium dahliae Kleb.) were examined at different plant growth stages using T-RFLP and 16S rDNA clone library. At flowering and bolling, soil samples from the rhizosphere of healthy cotton had the highest richness, whereas the highest evenness(More)
OBJECTIVE To evaluate the clinical significance of minimally invasive percutaneous new plate osteosynthesis (MIPPO) applied in three and four-part fractures of proximal humerus in elder patients. METHODS From June 2008 to December 2010, 98 old patients with three and four-part fractures of proximal humerus were treated with locking plate osteosynthesis.(More)
Wetland and floodplain soils in the East African Rift of Kenya provide a record of changing palaeoclimate and palaeohydrology compatible with climate records for the mid-Holocene through the late Holocene Medieval Warm Period (~AD 800–1270) and Little Ice Age (~AD 1270–1850), documented previously in nearby lacustrine sites. Soils forming from(More)
We measured stable carbon and nitrogen isotope ratios in 117 hair samples from American black bears (Ursus americanus) in Great Smoky Mountains National Park, Tennessee, during 1980-2001 from live-trapped bears. We also collected hair from bears with known diets to compare with the wild bears. We hypothesized that biological factors (age, mass, and sex),(More)
RATIONALE The condition of the pyrolysis reactor is very important for obtaining stable, precise hydrogen isotopic ratios using gas chromatography/thermal conversion/isotope ratio mass spectrometry (GC/TC/IRMS). However, few studies of the conditioning process have been conducted, and little is known about the best methods for high-precision hydrogen(More)
