He writes about viruses at <a href=”http://www.virology.ws” target=”_blank”>virology blog</a>.
  • Mice lacking the gene encoding toll-like receptor 2, a innate immune system sensor of microbes, do not develop insulin resistance when fed a high-fat diet – but only when the mice are raised in sterile conditions. Insulin resistance is turned off by changing the type of bacteria in the mouse gut.
  • Tuberculosis, the respiratory disease caused by Mycobacterium tuberculosis, is most commonly treated with the drugs isoniazid and rifampcin. Strains resistant to both drugs have emerged, and unfortunately the responsible mutations do not come with a fitness cost to the bacterium.

I’ll be back next Friday with more selections.

    Me compré una vgn fz240e hace 6meses sí la use 2 completos es mucho,cometí el error de pasarla de xp a w7,desde ahí siempre tiene un problema se apaga sola,y la mayoría de los driver no se consiguen,la webcam no se recuperó más,para mejor ahora no se la vendo a nadie,y en uruguay creo q no tenemos servicio técnico. Ojo, el servicio técnico de Sony Vaio en Santa Cruz, Bolivia, trabaja con la misma gente, al parecer, que en cualquier mercado lugar de la ciudad.
