BACKGROUND Among influenza viruses, type A viruses exhibit the greatest genetic diversity, infect the widest range of host species, and cause the vast majority of cases of severe disease in humans, including cases during the great pandemics. The hemagglutinin 1 (HA1) domain of the HA protein contains the highest concentration of epitopes and, correspondingly, experiences the most intense positi...
Infections of avian influenza virus (AIV) in turkey breeder hens can cause a decrease in both egg production and quality, resulting in significant production losses. In North Carolina in 2003, a triple-reassortant H3N2 AIV containing human, swine, and avian gene segments was isolated from turkey breeder hens (A/turkey/NC/16108/03). This viral subtype was subsequently isolated from both turkeys ...
BACKGROUND Current influenza vaccines need to be annually reformulated to well match the predicated circulating strains. Thus, it is critical for developing a novel universal influenza vaccine that would be able to confer cross-protection against constantly emerging divergent influenza virus strains. Influenza virus A is a genus of the Orthomyxoviridae family of viruses. Influenza virus nucleop...

A comprehensive study of the influence of classical anisotropy fields on the magnetic properties of Heisenberg antiferromagnets within unified molecular field theory versus temperature T , magnetic field H , and anisotropy field parameter h A 1 is presented for systems comprised of identical crystallographicallyequivalent local moments. The anisotropy field for collinear z -axis antiferromagnet...
In Aichi Prefecture, the first influenza outbreak of the 20052006 influenza season occurred from November to December 2005 in the northeast area (1). As of March 26, 2006, we had obtained a total of 182 influenza virus isolates from the respiratory specimens collected through the surveillance program in Aichi Prefecture. Of these, 70 (39%) were influenza AH1 virus, 106 (58%) were influenza AH3 ...
An H4N6 subtype avian influenza virus was isolated from a pockmark duck in southern China in November 2013 and named A/duck/Guangxi/149D24/2013 (H4N6). All eight gene segments of the strain were sequenced. Sequence analysis indicated that this H4N6 virus was a natural reassortant virus. This H4N6 virus has two basic amino acids in the cleavage site of hemagglutinin 1 (HA1) and HA2, and the amin...
Since the first appearance of the pandemic (H1N1) 2009 virus many efforts have been made to monitor the changes of the virus at molecular level with the aim to early detect mutations which could alter its pathogenicity. Some mutations have been observed more frequently in viruses that caused severe or fatal infections than in viruses involved in mild infections. Among these, the most common see...
It is shown that the heat operator in the Hall coherent state transform for a compact Lie group K [Ha1] is related with a Hermitian connection associated to a natural one-parameter family of complex structures on T ∗K. The unitary parallel transport of this connection establishes the equivalence of (geometric) quantizations of T ∗K for different choices of complex structures within the given fa...
