Seventy-three B/Victoria group strains isolated in the 1996-1997 influenza season were divided into three groups according to the degree of reactivity to monoclonal antibody 8E6. Analysis of nucleotide sequences of the HA1 region clarified that single amino acid substitutions were responsible for the difference in reactivity to 8E6.

One-hundred five influenza B-positive specimens obtained from southeast Asia in 2002 were categorized on the basis of DNA sequencing of HA1 gene as well as real-time PCR analysis of the NA gene. Phylogenetic analysis of the HA1 gene sequences showed that the majority of the viruses (96.2%) belonged to the B/Victoria/2/87 lineage, while a smaller percentage of the viruses (3.8%) belonged to the ...

The ideal of a Segre variety P1 × · · · × Pt ↪→ P(n1+1)···(nt+1)−1 is generated by the 2-minors of a generic hypermatrix of indeterminates (see [Ha1] and [Gr]). We extend this result to the case of SegreVeronese varieties. The main tool is the concept of “weak generic hypermatrix” which allows us to treat also the case of projection of Veronese surfaces from a set of general points and of Veron...

In this paper we study an elliptic variational problem regarding the $p$-fractional Laplacian in $\mathbb{R}^N$ on basis of recent result \cite{Ha1}, which generalizes nice work \cite{AT,AP,XZR1}, and then give some sufficient conditions under weak solutions to above are continuous $\mathbb{R}^N$. final appendix correct proofs both \cite[Lemma 10]{PXZ1} A.6]{PXZ} for $1<p<2$.

... When once the engine shall have been constructed, the difficulty shall ha1)e been reduced to the making out of cards; but as these are merely the translation of algebraical formulae, it will, by means of some simple notations, be easy to consign the execution of them to a workman. Thus, the whole intellectual labour will be limited to the preparation of the formulae, which must be adapted f...

To the editor: Kilander et al. (2010) [1] have previously reported that in some cases of patients with severe or fatal pandemic influenza A(H1N1), an amino acid substitution from aspartic acid to glycine occurs at position 222 (D222G) of the HA1 subunit of haemagglutinin (HA). In their study 11 (18%) of 61 patients with severe disease had the mutation, in contrast to 0 of 205 patients with mild...

Introduction Recently, fructose consumption has been suggested to be one of the environmental factors contributing to the development of insulin resistance, obesity, dislipidemia and other abnormalities of the metabolic syndrome. Aim Herbal extracts with established therapeutic efficiency in patients with obesity and diabetes have been traditionally used in Bulgarian ethnomedicine.This study in...

The antigenic variability of influenza viruses has always made influenza vaccine development challenging. The punctuated nature of antigenic drift of influenza virus suggests that a relatively small number of genetic changes or combinations of genetic changes may drive changes in antigenic phenotype. The present study aimed to identify antigenicity-associated sites in the hemagglutinin protein ...
