Scientists Target Future Pandemic Strains of H5N1 Avian Influenza (8/10/2007)

Preparing vaccines and therapeutics that target a future mutant strain of H5N1 influenza virus sounds like science fiction, but it may be possible, according to a team of scientists at the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health (NIH), and a collaborator at Emory University School of Medicine. Success hinges on anticipating and predicting the crucial mutations that would help the virus spread easily from person to person. ...> Full Article

Where Broken DNA is Repaired (8/10/2007)

Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. Intricate DNA repair mechanisms in the cells' nuclei are constantly working to fix what's broken, but whether the repair work happens "on the road" - right where the damage occurs - or "in the shop" - at specific regions of the nucleus - is an unanswered question. ...> Full Article

Multi-Center Study Nets New Lung Tumor-Suppressor Gene (8/8/2007)

Collaborating scientists in Boston and North Carolina have found that a particular gene can block key steps of the lung cancer process in mice. The researchers report in the journal Nature that LKB1 is not only a "tumor-suppressor" gene for non-small cell lung cancer in mice, it also may be more powerful than other, better-known suppressors. ...> Full Article

High-Intensity Ultrasound May Launch Attack on Cancer, Wherever It Lurks (8/8/2007)

An intense form of ultrasound that shakes a tumor until its cells start to leak can trigger an 'alarm' that enlists immune defenses against the cancerous invasion, according to a study led by researchers at Duke University's Pratt School of Engineering. ...> Full Article

Does This Child Have Appendicitis? Watch Out for Key Signs (8/7/2007)

A 5-year-old with abdominal pain, nausea and fever may have appendicitis or any of a number of other problems. But how does the child's doctor decide whether to schedule an emergency appendectomy to surgically remove a presumably inflamed appendix - a procedure that carries its own risks like any surgery - or wait and observe what could be a ticking time bomb that could rupture and kill the patient in a matter of hours? It's a classic physician's dilemma, but a new study led by the Johns Hopkins Children's Center may ease the pediatrician's problem-solving and parents' anxiety. ...> Full Article
