Nanotextured implant materials: blending in, not fighting back
...meter features strongly favored the adsorption and spreading of fibronectin, a protein that helps endothelial cells quickly coat the graft. Webster and Haberstroh's next step will be to test such nanostructured implants in live animals. If the same behavior holds true for materials placed in the body, the ra...Researchers create interactive map with Google technology to track avian flu spread

In one instance the supermap shows a direct line spreading from Thailand to Europe in a single rapid event, illustrating a 2004 incident when several infected ...'Supermap' of avian flu yields new info on source/spread
...important to track how this particular mutation is spreading because it appears to be so infective and deadly in mice," says Janies. For now, it appears that the H5N1 virus is not highly communicable to humans or between humans. But that could change quickly. Scientists say emerging, unpredictable mutations......or, crawl through tissues and enter blood vessels spreading the cancer throughout the body. Richard Klemke, Ph.D., professor of pathology at UCSD School of Medicine and the Moores Cancer Center, and his colleagues set out to better understand the complexity of signaling mechanisms within the cell that becom...Is climate change likely to increase disease in corals?
... Barrier Reef is white syndrome, a disease that is spreading rapidly, leaving stripes of dead corals like ribbons of death in its wake. In a new study published by PLoS Biology, John Bruno, Amy Melendy, and colleagues show that the interaction between anomalously high ocean temperatures and the extent of coral...LSU professor involved in genome sequencing of the first marsupial

...as a rare strain of the flu has a better chance of spreading through a population that is already immune to more common strains of the virus. In this case, flies carry one of two versions of the foraging gene (either the "rover" or "sitter" type). Rover larvae move around more than sitter larvae while feeding ...FDG-PET imaging clearly predicts lung cancer patients' response to chemotherapy
...st common type of lung cancer, usually growing and spreading more slowly than small cell lung cancer. Lung cancer is the second most common cancer and the most common cause of cancer-related death in both men and women in the United States. In 2007, about 213,380 new cases of lung cancer (both small cell and n...'Short-circuit' found in ocean circulation

...vated potatoes first appearing in Europe and later spreading worldwide, were first recorded outside of the Americas in 1567 on the Canary Islands Archipelago. Today, scientists believe that the remnant landraces of these early potatoes still grow in on the Canary Islands. For years, researchers have debated ...Landmark study details demographic, ecological and genetic spread of rabies in raccoon outbreak
...ere are no natural settings to keep the virus from spreading across the entire Midwest. "However, we can now model what the spread of the virus would look like and then intervene," says Dr. Real. Although raccoons are common throughout North America, their impact as a rabies host before the 1970s was limited...2007 Joint Assembly in Acapulco -- press conference schedule
