I still, by the way, have not had an infection. Not even a hint of one.

The majority of nvH1N1 infections are mild and self-limiting in nature, but a small percentage of the patients require hospitalization and sometimes emergency care. Unlike the seasonal flu virus, the people who seem to suffer serious complications from this [...] (Source: Laika's MedLibLog) Laika's MedLibLog blogs http://www.medworm.com/rss/comments.php?id=3104978 Fri, 18 Dec 2009 22:15:30 +0100 3104978 http://www.medworm.com/index.php?rid=3092651&cid=t_178883_86_f&fid=38272&url=http%3A%2F%2Flaikaspoetnik.wordpress.com%2F2009%2F12%2F16%2Fnot-one-rct-on-swine-flu-or-h1n1-outrageous%2F Last week doctorblogs (Annabel Bentley) tweeted: “Outrageous- there isn’t ONE randomised trial on swine flu or #H1N1“ Annabel referred to an article at Trust the Evidence, the excellent blog of the Centre for Evidence-Based Medicine (CEBM) in Oxford, UK.

Tracked down so far: regular flu shot pneumonia vaccine So far, no H1N1 has shown up on my personal health radar. The Health Department was offering 1500 or so of them, but one evidently had to stand for a couple of hours in the rain to get one. It was on the other side of town, too. So now my body is busy building antibodies, leaving me too sluggish to do much more than read blogs now.

Despite their relatively simple structure, viral channels can achieve highly specific gating and selection of ions, and the particular mechanisms appear to be different from those of prokaryotes and eukaryotes. The unique structural and functional properties of viral channels make them ideal targets for antiviral therapy because the molecules that inhibit viral ion channels may not interact with human ion channels. The M2 proton channel of influenza A virus is a model viral ion channel. This small channel, whose pore is formed by four equivalent transmembrane helices, is the target of two widely used anti-influenza A drugs, amantadine and rimantadine, both belonging to the adamantane class of compounds. However, resistance of influenza A to ...

The nucleoprotein (NP), the major protein component of RNPs, binds along the entire length of each genomic RNA segment at a 24-nt interval, forming the double-helical RNP structures found in mature viruses. The viral polymerase, consisting of PA, PB1, and PB2 subunits, binds to the two RNA termini of the RNP. As one of the most abundant proteins made in infected cells, influenza virus NP has essential roles in many important viral processes, including intracellular trafficking of the viral genome, viral RNA replication, viral genome packaging, and virus assembly. The recently determined crystal structures of two NP trimers show an overall fold and an exter...

It is comprised of two functional domains: N-terminal (amino acids 1-73) RNA-binding domain; and C-terminal (amino acids 74-230/237) effector domain. Here we focus on several of the best-characterized functional interactions of the NS1 protein. A major role of the NS1 protein is to counter host cell antiviral responses. Thus, the RNA-binding domain binds double-stranded (ds) RNA, thereby inhibiting the dsRNA activation of the antiviral oligo A synthetase/RNase L pathway that is induced by interferon-α/β (IFN-α/β). A region of the effector domain binds the protein kinase PKR, thereby preventing ...

This would not be entirely correct. The first high resolution electron microscopy images of the swine flu virus have been released which show that the virus is not spherical but rahter oblong in shape, as shown in the image below.

The results suggest that new strains usually begin in East and Southeast Asia, where they circulate continuously. These “seed” other outbreaks by proceeding first through Oceania, then Europe and North America, and eventually South America. But the paper indicates that viruses hardly ever go back in the other direction. The second paper used comparative genomics to assess the evolutionary dynamics of H3N2 and another influenza A strain, H1N1. These researchers also suggest that influenza A strains in one region seed outbreaks in the rest of the world, following a “source-to-sink” pattern, though this research didn’y implicate ...
