Batten down the hatches against HIV

A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation" into the corresponding, disease-related protein. A stumbling block has been the efficient and targeted delivery of RNA into the cells. Researchers led by Hongjie Dai at Stanford University have sucessfully used carbon nanotubes as a "means of transport," they write in "Angewandte Chemie."

   07-09-2007 · EurekAlert!
   Researchers from the University of Granada and Hospital Carlos III in Madrid, verified that maslinic acid -- found in wax from olive skin -- inhibits serin-protease, the enzyme used by HIV to release itself from the infected cell into the extracellular environment.

2. Does treating worms in people with HIV slow progression to AIDS?
   12-18-2007 · EurekAlert!
   There is evidence that co-infection of Helminth worms may result in a more rapid progression of HIV infection to AIDS. Does treating these worms ("de-worming") slow down this progression? In a new study published in PLoS Neglected Tropical Diseases, researchers set out to answer this question. Their study found that there were simply not enough data to make any firm conclusions, and they call for larger, well-designed studies to help come to a definitive answer.

3. MicroRNAs may be key to HIV's ability to hide, evade drugs, Jefferson scientists find
   09-30-2007 · EurekAlert!
   Tiny pieces of genetic material called microRNA could be key to HIV's ability to evade detection in the immune system. Researchers have shown that when an HIV-infected individual receives a powerful cocktail of antiviral agents called HAART, the virus uses miRNAs to help it hide and remain practically undetectable, temporarily shutting down its ability to replicate. Learning to manipulate miRNA's inhibitory effects might have implications for new strategies against the virus.

4. Striking shift seen among newly HIV-infected men regarding partners
   12-05-2007 · EurekAlert!
   "While the findings showed condom use was up and the number of partners was down, the most startling effect was seen in men choosing to have unprotected intercourse almost exclusively with other HIV-infected individuals. This reflects a systematic shift by men, most of whom are gay, following HIV infection to behaviors that protect their sex partners," said lead author, Wayne Steward, PhD, MPH, assistant professor of medicine at UCSF's Center for AIDS Prevention Studies.

   The death rate in New York City reached an all-time low in 2006, as the number of deaths fell to 55,391 -- down from 57,068 in 2005 and 60,218 in 2001. Mortality declined in eight leading categories, including diabetes, HIV, chronic lung disease and kidney failure. The only leading killer that increased significantly was substance use (up 8 percent).
