Teaching old drugs new tricks

Teaching old drugs new tricks
Scientists from the European Molecular Biology Laboratory (EMBL) discovered a new way to make use of drugs' unwanted side effects. They developed a computational method that compares how similar the side effects of different drugs are and predicts how likely the drugs act on the same target molecule. The study, published in Science this week, hints at new uses of marketed drugs. Similar drugs often share target proteins, modes of action and........Go to the Research news blog (Added on 7/10/2008 9:45:44 PM)


New discovery could lead to an improved influenza vaccine

New discovery could lead to an improved influenza vaccine
Findings just reported in the scientific journal Immunity by scientists at the Trudeau Institute shed new light on how a previously-unknown messaging mechanism within the human immune system prompts specific influenza-fighting cells to the lung airways during an infection. Infections from the influenza virus are responsible for hundreds of thousands of hospitalizations and as a number of as 40,000 deaths in the United States each year.........Go to the Infectious disease blog (Added on 7/10/2008 8:43:03 PM)


A short and sweet diagnosis for cancer?

A short and sweet diagnosis for cancer?
In order to provide the most effective therapys for cancer patients, it is essential to develop methods of sensitive and specific early detection of the disease. A team of researchers from the NIBRT Dublin-Oxford Glycobiology Laboratory at UCD has developed a system which aims to pinpoint potential "biomarkers" of early forms of the disease. They do this by looking at the structures of specific sugar molecules which are attached either to........Go to the Cancer-blog (Added on 7/9/2008 9:13:33 PM)

Young women's breast cancers have more aggressive genes
Young women's breast cancers tend to be more aggressive and less responsive to therapy than the cancers that arise in older women, and scientists at the Duke Comprehensive Cancer Center and the Duke Institute for Genome Sciences & Policy may have discovered part of the reason why: young women's breast cancers share unique genomic traits that the cancers in older women do not exhibit.
