Rectal Gel Could Help Ward Off HIV: Study
"Researchers have focused on the use of microbicides -- such as tenofovir -- as a preventive treatment to be used in vaginal sex. However, scientists think unprotected anal sex is much more risky." http://www.nlm.nih.gov/medlineplus/news/fullstory_109313.html |

Statins Might Help HIV Patients, Study Suggests
"It's not unusual for HIV patients to take these cholesterol-lowering drugs, because the medications commonly used to combat HIV can cause cholesterol levels to skyrocket." http://www.nlm.nih.gov/medlineplus/news/fullstory_109198.html |

"ScienceDaily (Mar. 9, 2011) New Instrument for Analyzing Viruses: Sensitive 'PING' Device Scientists in Israel and California have developed an instrument for rapidly analyzing molecular interactions that take place viruses and the cells they infect. By helping to identify interactions between proteins made by viruses like HIV and hepatitis and proteins made by the human cells these viruses infect, the device may help scientists develop new ways of disrupting these interactions and find new drugs for treating those infections..." |

I posted this article in the Interesting articles about cancer forum, but I am re-posting it here as my personal research suggests anti-cancer substances can sometimes turn out to damage the HIV virus as well, so some of them may be worth a little extra attention in the FAAH screenings against HIV.
http://www.medicalnewstoday.com/articles/218423.php "Article Date: 07 Mar 2011 Scripps Research And MIT Scientists Discover Class Of Potent Anti-Cancer Compounds Working as part of a public program to screen compounds to find potential medicines and other biologically useful molecules, scientists from The Scripps Research Institute and Massachusetts Institute of Technology (MIT) have discovered an extremely potent class of potential anti-cancer and anti-neurodegenerative disorder compounds. The scientists hope their findings will one day lead to new therapies for cancer and Alzheimer's disease patients..." |

[...] HIV exploits cellular proteins involved in the loading, sorting and budding of cellular vesicles known as ESCRT proteins. During budding, HIV makes use of ESCRT to cut the last connection between the virion coat and the cell surface, allowing it to exit the cell. The enzyme VPS4A forms part of the ESCRT machinery and is known to be necessary for the disassembly of the complex after use, allowing its components to be recycled. The results from ultrasensitive live-cell imaging experiments showed that VPS4A also acts at an earlier stage in the budding process. In the new work, the researchers labeled the enzyme by fusing it with the Green Fluorescent Protein (GFP). This allowed them to track the protein in living cells. By recording the fluorescent signals, they observed how several VPS4A molecules came together to form larger complexes. "In this case, we were able to count how many enzyme molecules assembled at the HIV budding site during its interaction with the nascent virion" says Müller. Complexes made up of about three dodecamers of VPS4A were observed to undergo transient activation (for about a minute) at a budding site. Shortly thereafter, the virions were observed to emerge from the cell at these locations. Because virion release does not follow immediately upon activation of the enzyme, the investigators believe that at least one further intermediate step is required for budding. [...] |

"Article Date: 11 Mar 2011 New Study: HIV, Bone Density, CD4 Cells And Fracture The HIV virus ravishes the body on many levels including bone mineral density, which in turn causes a higher frequency of bone fractures. Until now, there has been little study of this actual relation, but now we know that those infected have an up to almost four percent higher risk of ending up in a cast. Simply stated, the higher the bone mineral content, the denser the bones are. And the denser the bones, the stronger they generally are and the less likely they are to break..." |
