Misuse of Tamiflu can create resistant influenza viruses (10/4/2007)

Swedish researchers have discovered that oseltamivir (Tamiflu), an antiviral drug used to prevent and mitigate influenza infections is not removed or degraded during normal sewage treatment. Consequently, in countries where Tamiflu is used at a high frequency, there is a risk that its concentration in natural waters can reach levels where influenza viruses in nature will develop resistance to it. ...> Full Article

New Treatment for Stroke Works up to a Day After Symptoms Start (10/2/2007)

People treated with the drug minocycline within six to 24 hours after a stroke had significantly fewer disabilities, according to a study published in the October 2, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers say minocycline may be an alternative treatment for stroke because current treatments only work during the first few hours after the onset of symptoms, and many people don't get to the hospital in time to be treated. ...> Full Article

MicroRNAs may be key to HIV's ability to hide, evade drugs (10/1/2007)

Tiny pieces of genetic material called microRNA (miRNA), better known for its roles in cancer, could be a key to unlocking the secrets of how HIV, the AIDS virus, evades detection, hiding in the immune system. Researchers at Jefferson Medical College in Philadelphia have shown that when an individual infected with HIV receives a powerful cocktail of antiviral agents called HAART (highly active antiretroviral therapy), the virus calls on miRNAs to help it remain quiet and practically undetectable, temporarily shutting down its ability to replicate and infect. ...> Full Article

Researchers discover one of the mechanisms that prevents the spread of colon cancer (10/1/2007)

The first step in the development of colon cancer is the formation of benign tumours, called adenomas, in the intestine. Over time, these tumours may progress to produce colon cancer if they undergo a series of mutations and genetic alterations. ...> Full Article

Ozone shuts down early immune response in lungs and body (10/1/2007)

As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria. ...> Full Article

Second pathway behind HIV-associated immune system dysfunction identified (10/1/2007)

Researchers may have discovered a second molecular "switch" responsible for turning off the immune system's response against HIV. Last year members of the same team identified a molecule called PD-1 that suppresses the activity of HIV-specific CD8 T cells that should destroy virus-infected cells. Now the researchers describe how a regulatory protein called CTLA-4 inhibits the action of HIV-specific CD4 T cells that control the overall response against the virus. ...> Full Article

Researchers say lack of sleep doubles risk of death, but so can too much sleep (9/29/2007)

Researchers have found that lack of sleep can more than double the risk of death from cardiovascular disease. However they have also found that point comes when too much sleep can also more than double the risk of death. ...> Full Article

New Research Shows How H5N1 Virus Causes Disease (9/29/2007)

Avian Influenza H5N1 virus affects much more than respiratory system: disseminates to gastrointestinal tract, immune and central nervous systems, and can be transmitted mother to fetus through placenta ...> Full Article

Altering the fingerprint of cancer (9/29/2007)

It has become clear over the past few decades that cancer is a genetic disease, with vast combinations of gene mutations, translocations, additions, and deletions contributing to the diverse cancers that afflict humans. Given this knowledge, a sea change is brewing in the search for new cancer treatments. ...> Full Article

Researchers investigate new suspect in West Nile deaths of pelicans (9/28/2007)

Stable flies are the latest suspect that may be involved in the West Nile virus deaths of hundreds of pelican chicks at the Medicine Lake National Wildlife Refuge in northeast Montana. West Nile virus killed 800 to 1,000 pelican chicks in 2003, averaged 400 in each of the next three summers and more than 600 this year. ...> Full Article

Prostate cancer survival affected by seasons (9/28/2007)
