...drug developer, HIV is nothing but a thief. All the virus wants to do is break inside a healthy cell, steal its genetic machinery, and start profiting from the intrusion. To stop a thief, you need to throw a monkey wrench - or several - into his plans...
...last night that his proposed 2008 fiscal budget will provide the option of free human papillomavirus (HPV) vaccinations for girls aged 9 to 18, as part of a $72 million increase in state public health funding. The vaccine, known as Gardasil, helps to prevent the spread of the HPV virus, which infects about 6.2 million people in the U.S. each year. The virus is transmitted through genital contact and can lead to cervical cancer and genital warts, according to the Center for Disease Control and Prevention. Although the proposed vaccination program does not apply to the majority of undergraduates...
...extraterrestrial bouquet, a blossom from another galaxy. But it is a revelation from a skirmish in deepest inner space, one with huge potential promise in the war against AIDS. The twisting green "stems" are a rare antibody called b12; the red "florets" are a surface protein of the HIV virus; and the yellow area where they meet is the virus' point of vulnerability, where the b12 antibody latches on to start neutralizing the deadly entity that causes AIDS. The 3-D X-ray crystallographic image, released as part of a paper that appears in the journal Nature, is more than...
...While b12 is a rare antibody, occuring in only a very few individuals, what it does to this particularly vulnerable protein in the HIV virus has now been documented in great detail in the new study. The b12 antibody thus provides a key to scientists: its behavior will give them a precise roadmap on which to develop potential vaccines that would replicate b12's actions. One other advantage of b12 and its target protein (which is called HIV gp120): while the HIV virus is known to mutate over and over again, the HIV gp120 protein is stable throughout the existing...
...world health organization (WHO) representative on pandemic influenza, Dr. David Heymann has one of the most important jobs in medicine: coordinating international preparations for a possible virus outbreak that could threaten millions of lives. That job got much harder on Feb. 7, when Indonesia announced it had stopped sharing with the WHO the samples of H5N1 avian-flu virus it had isolated. Simultaneously, Jakarta announced an agreement with U.S. drug company Baxter International, which will develop a vaccine from the strains and give Indonesia technical assistance in manufacturing it. For 50 years, the WHO has received free influenza-virus samples...
