...that cell that is suddenly sparking the interest of cancer researchers and molecular biologists around the world. Known as a cancer stem cell, it could be the culprit behind a malignant tumor's nasty habit of recurring year after year and popping up in distant parts of the body long after the primary growth is gone. Studies of that cell are helping scientists unravel some of cancer's deepest secrets and leading doctors closer to the ultimate goal of any cancer therapy--a cure. Think of the stem cell as a tumor's master print; as long as the original...
...distraction from the tiny percentage of cells--perhaps as few as 3% to 5%--that are the real culprits. At the latest meeting of the American Association for Cancer Research, researchers at City of Hope Cancer Center in Duarte, Calif., announced that they had isolated a group of stem cell--like cells in lungs that seed the abnormal growth of small-cell lung cancers. Scientists at Stanford University took the concept even further. They were able to isolate stem cells from breast-cancer tumors and identify a genetic signature that allowed them to predict the progression of the disease. "Everybody...
...members of the European Union. For now, Hamas leaders, facing dwindling postelection optimism, can be glad that popular frustration and anger are pointed at Israel, the U.S. and Europe. Flexibility on the part of the international community would ease their difficulties, but meanwhile Hamas must find a way to stem the crisis or risk having opprobrium turned...
...Israel has suspended monthly payments of approximately $50 million in tax and customs revenues it collects for the Palestinians. And it will not talk to Hamas until it halts attacks on Israel by all Palestinian factions. Even as Hamas, which has itself held to a cease-fire, tries to stem attacks by other militants, Israel says it will continue to retaliate, increasing economic damage...
Both bullpens managed to stem the tide in the later innings: Yale held the dynamic Harvard offense to one run over the final four innings, while Wilson and senior Lance Salsgiver permitted just two hits over the final five frames. Salsgiver pitched two perfect innings in his stint...
