    <p> the superposition of two does not mean that one plus one equals two. "We can only say that the possibility of" Guo Xing experts say. H9N2 has been isolated in the human body, this time H7N9 appeared in the crowd, in his view,parajumpers dames jas, and some features may be related to H9N2. But in fact, H7 subtypes of the virus,hogan donna, and there is no lack of precedent infect humans. Avian influenza family genealogy H7N9 infections in poultry have not had the human condition, the Chinese had also not found the virus Influenza A virus is a big family. It H (hemagglutinin) and N (neuraminidase) subtypes to distinguish different species. Where H's appearance is very eye-catching,spaccio hogan milano, like a spear, like projections on the virus surface. H and N both to some extent determines the ability of the virus to enter cells and finally to diffuse out of the cell. More simply,scarpe hogan uomo outlet online, H like carrying a key,hogan donna, it is through a combination of live-cell receptor,hogan donna, opened the lock of living cells, into cells. And after N is finished copying the virus,hogan interactive donna, tearing cells, after the virus replicate unimpeded leave the cell. There are 16 H subtypes,hogan interactive, N has nine subtypes. They will be with each other mathematical combination,hogan 2014, should have 144 kinds of speculation with the result.</p>

    <p> for example,hogan donna, belong to the avian influenza virus. But Jin Qi that "belong to the same type of virus reassortment high probability." In simple terms,hogan sito ufficiale, the occurrence of reassortment virus refers to the re "assembly" between two different viruses. For eight gene segments of bird flu virus, the virus recombinant many forms. Guo Xing experts used a vivid metaphor - after the demolition of two tables assembled into a - "could you use a table with four legs which may also use only one; another and another table parts assembly, but eventually a shape of the table. " H7N9 reassortant after retained its external form,hogan olympia outlet, which is the surface of the virus hemagglutinin (H) and neuraminidase (N). The six gene fragments all from inside the H9N2. This is a huge change. It seems odd in gold, even a gene is changed,hogan scarpe, are likely to make the virus exhibit new features. One of the most immediate question is whether it will carry the virus H9N2 of features? "It takes time to judge." Jin Qi that from genetic phenotype is concerned,parajumper jas, it will carry the characteristics of H9N2; but in terms of biological characteristics.</p>

    <p> As of yesterday,hogan bianche, 14 people have infection,hogan scarpe, were more in critical condition. H7N9 bird flu virus is a subtype of the virus. However, compared with the previous body found in poultry H7N9, H7N9 gene sequences of the human body found has changed. Chinese Center for Disease Control published gene sequence,outlet hogan online, the two gene fragments of the virus from the avian H7N9 virus,hogan rebel, the other six gene fragments derived from H9N2 viruses. "Reassortant virus has occurred." Jin Qi, said reassortant influenza virus is high probability of a change in the way. Reassortment usually occurs when two viruses simultaneously infect a host, they enter the same cell. "This does not necessarily happen reassortment, but will lead to such a possibility." Guo Xing National Health and Family Planning Commission expert group emphasized the prevention of influenza in the reconstitution process, the two virus should belong to one type.</p>
