We characterized 7 highly pathogenic avian influenza A(H5N1) viruses isolated from poultry in China during 2009-2012 and found that they belong to clade 2.3.4 but do not fit within the 3 defined subclades. Antigenic drift in subtype H5N1 variants may reduce the efficacy of vaccines designed to control these viruses in poultry.
We characterized two novel highly pathogenic H5N6 influenza viruses isolated from Chinese poultry in 2013. Genomic analysis showed that both isolates were reassortants, and derived their genes from H5 and H6 subtype viruses found in poultry in China. The virulence of the two isolates was examined in chickens and mice, and both isolates were found to be(More)
Infrasound is a kind of environmental noise and threatens the public health as a nonspecific biological stressor. Upregulated expression of corticotrophin releasing hormone (CRH) and its receptor CRH-R1 in the neurons of hypothalamic paraventricular nucleus (PVN) was reported to be responsible for infrasonic noise-induced stress and injuries. Recent studies(More)
Tob (transducer of ErbB2) is a negative cell cycle regulator with anti-proliferative activity in the periphery. Using a behavioral screening paradigm to look for novel gene functions in the brain, we identified Tob as a brain-expressed protein involved in learning and memory. Behavioral training of fear-conditioning triggered a transient elevation of Tob(More)
In China, domestic ducks and wild birds often share the same water, in which influenza viruses replicate preferentially. Isolation of 2 novel reassortant highly pathogenic avian influenza (H5N5) viruses from apparently healthy domestic ducks highlights the role of these ducks as reassortment vessels. Such new subtypes of influenza viruses may pose a(More)
In this study, the complete genomic sequence of a novel reassortant H9N2 avian influenza virus (AIV) from domestic ducks in eastern China was reported. Phylogenetic analysis showed that seven of the eight genes were all highly homologous to the chicken-origin H9N2 viruses, whereas the PB2 gene was homologous to the human-origin H1N1 virus, which suggested(More)
BACKGROUND Although extensive data demonstrates that the majority of H6 duck isolates belonged to a single H6N2 virus lineage with a single gene constellation in southern China from 2000 to 2005, the prevalence of H6N2 virus in poultry in Eastern China is largely unknown. RESULTS Epidemiology revealed that H6N2 viruses were the most frequently detected(More)
Magnetic skyrmions are promising for building next-generation magnetic memories and spintronic devices due to their stability, small size and the extremely low currents needed to move them. In particular, skyrmion-based racetrack memory is attractive for information technology, where skyrmions are used to store information as data bits instead of(More)
Pigs are susceptible to infection with both human and avian influenza A viruses and are considered intermediate hosts that facilitate virus reassortment. Although H5N1 virus has spread to a wide range of avian and mammalian species, data about swine H5N1 isolates are scarce. To determine whether Asian H5N1 influenza viruses had been transmitted to pigs, a(More)
Fatty acid synthase (FAS) is a key enzyme of lipogenesis. In this study, the FAS mRNA expression patterns were examined in three fat related tissues (liver, breast and thigh) at different developmental stages in two chicken breeds (Beijing-You, BJY and Arbor Acres broiler, AA). Results of the Real time-qPCR showed that the expression of FAS mRNA level in(More)
