Grapefruit against hepatitis C

The hepatitis C virus does not integrate its genetic material into the chromosomes of the host cells, so theoretically it can be completely removed from the body if the infection of healthy cells is stopped.

Now the runny nose can be studied on mice

Specialists from Imperial College London have bred mice capable of suffering from rhinovirus infection. Previously, the study of the pathogenesis and the search for methods of treating the "contagious cold" were difficult, since the virus could only affect humans and higher primates.
