Arthritis patients being treated with the drug rituximab should be given flu vaccinations immediately before treatment begins or several months later, but not in the first two months after treatment, Dutch researchers have found. The vaccine is not dangerous when given after treatment with the d... Read More
In the 1980s, Harald zur Hausen and his co-workers discovered that specific types of human papillomavirus (HPV) cause cervical cancer. Scientists soon found out how these pathogens cause cells to degenerate. It is known today that the main culprits are viral proteins E6 and E7. Both proteins swi... Read More
Scientists already know that smallpox, measles, tuberculosis, seasonal influenza and severe acute respiratory syndrome (SARS) can be transmitted during commercial flights. Now, in the first study to predict the number of H1N1 flu infections that could occur during a flight, UCLA researchers foun... Read More
A new retrovirus, xenotropic murine leukaemia virus-related virus (XMRV), first identified in tumor tissue of individuals with prostate cancer, was subsequently found in 68 of 101 US patients with chronic fatigue syndrome (CFS). This observation raised the possibility that XMRV is the etiologic ... Read More
