...This was not a deliberation of a purely scientific nature. Frist, a former heart and lung transplant surgeon, carries weight with this White House - because he is a physician, because he has a personal friendship with the President, and also because of his official role as the Senate?s Liaison to the White House. With his decision, the Senator has sent a message to President Bush, who is currently embroiled in the most contentious issue of his short term: Should he or should he not give the go-ahead to federal funding for embryonic stem cell research? Frist's proposal...
...nearly 30,000 tons of arsenic are believed to be at large. Investigators testing soil in the state's playgrounds have found arsenic levels far higher than hazardous-waste experts consider safe. Prolonged exposure can lead to nerve damage, dizziness and numbness, as well as increased risk of bladder, lung and skin cancer...
...eventually doctors diagnosed arsenic poisoning. The price he has paid is high: he lost a third of his overall motor control, and, even today, his face remains partly paralyzed. "My eye droops; I have weakness in my arms and legs," he says. "My long-term risk for bladder, lung and other problems is magnified enormously...
...course, technology has advanced considerably since then. The sophisticated pump used in last week's operation is designed to be completely implanted. Developed by Abiomed in Danvers, Mass., with funding from the National Heart, Lung and Blood Institute, the softball-size device is charged across the skin, so there's no need for chest tubes. Its batteries are miniaturized, and its pumping chambers are lined with a specialized coating that should cut down on blood clots...
Does that mean we should forget about total artificial hearts like Abiomed's? Not at all. There will always be some folks whose hearts are so worn out they cannot be salvaged. A review panel convened by the National Heart Lung and Blood Institute in 1999 estimated that between 5,000 and 10,000 patients a year might be helped by the development of total artificial hearts. But as with many medical advances, the early going will probably be grim. Doctors in Louisville will consider their experiment an astounding success if their patient manages to live an extra two months...
