Molecular anatomy of influenza virus detailed

...able to visualize influenza virus particles should boost our efforts to prepare for a possible pandemic flu attack," says NIAMS Director Stephen I. Katz, M.D., Ph.D. "This work will allow us to 'know our enemy' much better." One of the difficulties that has hampered structural studies of influenza virus ...

H9N2 avian flu vaccine paired with adjuvant provokes strong human immune response at low doses

...uvant is a substance that is added to a vaccine to boost the body's immune response to the vaccine's antigen. "In the event of an influenza pandemic, adjuvanted vaccines could provide a way to extend a limited vaccine supply to more people," he adds. In 1999, two children in Hong Kong became infected wit...

Renewed dolphin slaughter prompts new campaign

...e public awareness of the dolphin drive hunts , to boost measurable support through the group's website petition ( www.actfordolphins.com ) which currently includes over 22,000 signatures, and to convince the Japanese government to end the hunts on ethical grounds. According to the group, the ethical a...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...The discovery, they say, could lead to new ways to boost the effectiveness and reduce undesired side effects of steroid-hormone treatments and cancer drugs. The study, published online this week ahead of regular publication in the Proceedings of the National Academy of Sciences, also uncorks an almost 1...

Pair of microRNA molecules controls major oncogene in most common leukemia

...with a much more aggressive cancer." Drugs that boost production of these two natural TCL1 inhibitors might work as a future treatment for B-cell chronic lymphocytic leukemia, he said. These molecules could also be combined with 12 other miRNAs known to be associated with B-CLL to provide a test that ma...
