The worldwide circulation of H9N2 avian influenza virus in poultry, the greater than 2.3 % positive rate for anti-H9 antibodies in poultry-exposed workers, and several reports of human infection indicate that H9N2 virus is a potential threat to human health. Here, we found three mutations that conferred high virulence to H9N2 virus in mice after four(More)
An amphiphilic thermo-responsive ABA triblock copolymer, poly(methyl methacrylate)-b-poly(N-isopropylacrylamide-co-poly(ethylene-glycol) methyl ether methacrlate)-b-poly(methyl methacrylate) (PMMA-b-P(NIPAM-co-PEGMEMA)-b-PMMA), was designed and synthesized via reversible addition fragmentation chain transfer (RAFT) polymerization, and subsequently(More)
The circulation of H9N2 viruses throughout the world, along with their expanded host range, poses a potential health risk to the public, but the host responses to H9N2 virus in mammals were little known. To obtain insight into the host immune responses to the avian H9N2 virus, the expressions of both cytokines and chemokines in the lungs of infected mice(More)
H9N2 avian influenza viruses circulate worldwide in poultry and have sporadically infected humans, raising concern whether H9N2 viruses have pandemic potential. Here, we use a guinea pig model to examine whether serial passage results in adaptive viral changes that confer a transmissible phenotype to a wild-type H9N2 virus. After nine serial passages of an(More)
The aim of this study was to establish a method for discriminating Dendrobium officinale from four of its close relatives Dendrobiumchrysanthum, Dendrobium crystallinum, Dendrobium aphyllum and Dendrobium devonianum based on chemical composition analysis. We analyzed 62 samples of 24 Dendrobium species. High performance liquid chromatography analysis(More)
BACKGROUND Polyporus umbellatus is an important medicinal fungus distributed throughout most area of China. Its wide distribution may have resulted in substantial intraspecific genetic diversity for the fungus, potentially creating variation in its medical value. To date, we know little about the intraspecific genetic diversity of P. umbellatus. (More)
Double-hydrophilic block copolymer composed of poly(N-vinylpyrrolidone) (PVP) and poly(styrene-alter-maleic anhydride) (PSMA) has been synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. Poly(N-vinylpyrrolidone)-block-poly(styrene-alter-maleic anhydride) (PVP-b-PSMA) thus formed was characterized by gel permeation(More)
A novel amphiphilic ABC triblock copolymer, poly(N-isopropylacrylamide)-b-poly(styrene-alternate-maleic anhydride)-b-polystyrene (PNIPAAm-b-PSMA-b-PSt), was designed and synthesized by reversible addition fragmentation chain transfer polymerization. The copolymer can disperse in aqueous media at room temperature to self-assemble into pH- and(More)
The concentrations of seven heavy metals (HMs) in jujube samples collected from Hetian region (HTR), Hami region (HMR), Erkesu region (ESR), Bayikuleng region (BLR), and Turpan region (TUR) were determined by inductively coupled mass spectrometry (ICP-MS). The accuracy and precision of the analytical method were confirmed by the certified reference material(More)
(2016). Effects of mycorrhizal fungus Mycena sp. on the growth and polysaccharide properties of Dendrobium officinale. Dendrobium officinale Kimura et Migo (Orchidaceae), an endangered species, is a medicinal plant and the sole origin plant of Dendrobii Officinalis Caulis (Tiepishihu), a rare Chinese herbal medicine. Several photosynthetic orchids have(More)
