Researchers from Utrecht University, The Netherlands, have developed a model that illustrates how HIV evades the immune system. The study, published July 18th in the open-access journal PLoS Computational Biology, incorporates detailed interactions between a mutating virus and the immune system.

In industrialized countries, persons infected sexually with HIV now appear to experience mortality rates similar to those of the general population in the first 5 years following infection, though a higher risk of death remains as the duration of HIV infection lengthens, according to a study in the July 2 issue of JAMA.

Adult circumcision is safe in HIV-infected men without advanced HIV disease, according to research published in PLoS Medicine.

Soon after an individual becomes infected with HIV the virus infects cells in the brain and spinal cord (the central nervous system [CNS]).

One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes. A major step in that direction is the cataloguing of the “complete” salivary proteome, a set of proteins in human ductal saliva, identified by a consortium of three research teams, according to an article published today in the Journal of Proteome Research.

Swedish Radio news reports claim that many people here are being forced to pay for their AIDS and HIV medicines - which are supposed to be handed over without any cost.

A mathematical model shows that a new wave of drug-resistant HIV is rising among among men in San Francisco who have sex with men and that this trend will continue over the next few years, according to a new study from the UCLA AIDS Institute.

February 7th was proclaimed National Black HIV/AIDS Awareness Day. Making this step the Florida Department of Health highlights the disproportionate impact of HIV/AIDS on the black community and encourages people to learn more about HIV/AIDS.
