...Harvard professor of cell biology and pediatrics, Mark T. Keating, and an instructor in pediatrics at the Harvard-affiliated Children’s Hospital, Felix Engel, administered two drugs to rats who had suffered induced heart attacks. One of the drugs targets p38 MAP kinase, an enzyme that prevents heart muscle cells from undergoing cellular division. The other is FGF1, a growth factor that promotes the creation of new blood vessels...
Heart muscle cells, or cardiomyocytes, “need a blood supply and oxygen to survive,” said Engel. “FGF1 did not have a great effect on cell proliferation, but we found it was providing a new blood supply. If you just inhibit p38 MAP kinase, you don’t get blood vessels...
...same time, a brand-new probe called Mars Reconnaissance Orbiter began its mission to map Mars' surface with unprecedentedly sharp-eyed cameras, ground- penetrating radar and other instruments. The cameras are so powerful that they can actually see Opportunity, which is about the size of a golf cart, from nearly 200 miles up. They can also help find safe routes for the rover. But more important, they will give scientists a map of Mars that will make future exploration--ultimately by humans--much easier to plan...
...recent study headed by researchers at the Harvard-affiliated Dana-Farber Cancer Institute has identified a complete map of the genetic regions that may influence how estrogen contributes to breast cancer—results that could advance clinical treatment for breast cancer patients. The study identifies the molecular “control panels,” which consists of thousands of on-off switches for genes, that may be part of the mechanism by which estrogen regulates breast cancer. The findings—to be published in Nature Genetics this month—may help individualize treatment for breast cancer...
...them. Sharon insisted that Israel would keep its key West Bank settlements and the Jordan valley, and would never share Jerusalem; the route of his security wall leaves the Palestinians hemmed in to two parcels of West Bank land, and Olmert has based his unilateral withdrawal plan on the map created by that wall. Last week Olmert even proclaimed that the Golan Heights, Syrian territory captured by Israel in the 1967 war, is "an inseparable part of the State of Israel." In other words, the current Israeli government has nothing to offer Arab moderates...
