Zoonotic transmission of pathogenic avian influenza virus (AIV) is a potential public health threat (1, 2), as the virus may acquire human-to-human transmissibility through mutations or by reassortment with seasonal influenza viruses (e.g., H3N2 and H1N1). The recent outbreak of novel H7N9 virus in China is an enigma (3). In contrast to outbreaks of human infections by other avian influenza vir...

BACKGROUND AND AIMS Previous work conducted by our group has shown that the accumulation of hepatic natural killer (NK) cells and the up-regulation of natural cytotoxicity receptors (NKP30 and NKP46) on NK cells from patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) were correlated with disease progression in HBV-ACLF. The natural cytotoxicity receptors expressed...

Planar chiral h6-arene chromium(0) complexes are finding increasing application in the synthesis of enantioenriched compounds by serving as enantiopure starting materials or ligands for catalytic asymmetric processes.[1,2] Whereas early methods of generating enantiopure 1,2-disubstituted h6-arene chromium(0) complexes relied on resolution of racemates,[3] many methods have been developed recent...

Coagulase-negative staphylococci (CoNS) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. The aim of the current study was to investigate the presence of blaZ (responsible for penicillin resistance) and mecA (responsible for methicillin resistance) genes among 108 CoNS belonging to 9 different species isolated from bovine mastitis in seven dairy herds (H1-...

Cotton (Gossypium hirsutum L.) mRNA (H6) is expressed predominantly in fiber cells and is present during early primary cell wall formation. However, H6 protein is found to accumulate during later stages, when active secondary cell wall formation occurs, indicating possible regulation at the translational level and function in the secondary cell wall assembly. The nucleotide-derived amino acid s...

The effects of amiloride, a reported inhibitor of serum-stim ulated sodium influx, were tested on tumor growth, tumor cell proliferation, and intracellular element content of cancer cells in vivo. We have shown previously that cancer cells have high intranuclear levels of sodium compared to those of their normal counterpart cells and have postulated that such a high level of sodium may be invol...

Until 2001, H6N1 influenza viruses in the Hong Kong bird markets were represented by a single stable A/teal/Hong Kong/W312/97-like lineage. Beginning in 2001, despite a reduction in overall prevalence, an increase was observed in the number of H6 viruses isolated from chickens and other hosts. To assess any changes in H6 viruses, we characterized 18 H6 viruses isolated in the Hong Kong bird mar...

efficient use of natural and biological cycles such as nitrogen fixation by legumes may stimulate yield of non-legumes crops in an intercropped system. in order to evaluate spring barley (h) and annual alfalfa (m) intercropping, a study was conducted in the research field of university of tehran (located in karaj) during 2009-2010 growing season. in this research, a randomized complete block de...
