No bail for six medics in Libyan HIV sham

Five Bulgarian nurses and a Palestinian doctor who have been imprisoned in a Libyan jail since 1999 on spurious charges of deliberately infecting more than 400 children with the HIV virus, have had their request to be released on bail rejected.

Scientists unlock more secrets of HIV and SARS

UK scientists have cracked one of the key biological processes used by viruses such as HIV and SARS when they replicate according to a paper published in the journal Nature tomorrow (11 May). Viruses are able to interfere with the host cell processes that our bodies use to replicate cells, and protein synthesis is often one of their targets.

Renewed interest in studying influenza A viruses

The emergence of the avian influenza virus H5N1 that is currently devastating chicken flocks in many countries and threatening to unleash a worldwide epidemic among humans has triggered a renewed interest among scientists in studying influenza A viruses, according to investigators at St. Jude Children's Research Hospital.

Many pregnant not tested for HIV

Despite state laws requiring that every pregnant woman be offered HIV testing multiple times during pregnancy, about 20 percent of women reach their third trimester without it, according to a review of Florida women from 2003-04, researchers say.

Effective gene suppression using small interfering RNA in hard-to-transfect human T cells

A technical advance in laboratory techniques may provide biology researchers broader access to RNA interference, a process of blocking the activity of targeted genes. RNA interference has recently emerged as an important tool in studying how genes function in normal biological processes and in disease.

Discovery of new type of cell that generates crucial immune system cells

A new type of cell that generates crucial cells of the immune system has been discovered at The Walter and Eliza Hall Institute.

Chancroid vaccine may help control HIV in Africa

HIV plagues more than 25 million people in sub-Saharan Africa, according to the World Health Organization, and efforts to develop a vaccine against the virus have achieved limited success.

Gay men who are HIV-positive rarely regret revealing their health status to others

The study, the first of its kind, could be important for clinicians who work with HIV-positive men who are often uncertain whether to tell friends, family, co-workers or others about being diagnosed with the virus that causes AIDS.

SLU Liver Center to study effectiveness of tenofovir in treating hepatitis B

Saint Louis University School of Medicine researchers are studying the effectiveness of a drug for patients with chronic hepatitis B that is currently used to treat HIV.

New study describes molecular basis of NeuroAIDS

Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.

Outcome of patients with hepatitis B and HIV infections referred for liver transplantation

A new study on HIV patients who also had Hepatitis B virus (HBV) found that better outcomes are possible if they are referred early for transplant and treated with a combination of drugs for HBV. It is essential to monitor the HBV status of these patients, however, in order to control the emergence of drug-resistant HBV infection.

Good and bad sides of the Internet as it relates to children

Between 75 and 90 percent of teenagers in the United States use the Internet to email, instant message (IM), visit chat rooms and explore other sites on the World Wide Web.

Study investigates early biology of HIV infection

In July 2005, the race to find a vaccine that would stem the worldwide rate of 13,000 new cases of HIV infection each day moved from competition among research institutions to a strategy of cooperation.

'Resonance' may be the reason for virologic failure in STI drug therapy

Researchers have been puzzled over why HIV-positive patients who have periodic, built in interruptions in their drug therapy reach a point where the therapy no longer reduces their viral loads, even in the absence of any evidence of acquired drug resistance.
