...just like ordinary mice, with no evidence of seizures or convulsions, according to Tsien. That's critical. The NMDA receptor shows up throughout the brain, and though calcium is crucial to learning and memory, too much of it can lead to cell death. That's what happens during a stroke: when brain cells are deprived of oxygen, they release huge amounts of glutamate, which overstimulates nearby NMDA receptors and kills their host cells. Nature may have designed NR2B-based receptors to taper off in adult brains for a reason. Some scientists fear that the altered mice may be prone...
...past 25 years, doctors in the U.S. have warned their patients about the dangers of high blood pressure, a generally symptomless condition that increases the risk of heart disease, kidney failure and stroke. By aggressively treating folks whose readings exceed the normal limit of 140/90 mm Hg at rest, physicians have prevented millions of premature deaths and untold suffering. But it looks as if we've stopped getting the message. A national health survey released two years ago showed that blood-pressure rates are no longer falling; at the same time, the incidence of stroke has started to rise...
...UNLUCKY STROKES Though the benefits of heart surgery clearly outweigh the risks for most patients, a stroke during or after such an operation can be a devastating complication for some people. Being female or diabetic, for example, triples the risk of stroke. At highest risk, however, are those patients who have had a stroke prior to heart surgery; for them, the chances that another stroke will occur rise 14-fold...
...feel like one, but in reality it's an animated, digital dancer, projected onstage in Biped, a hypnotic, groundbreaking performance by the Merce Cunningham Dance Company. In a single stroke, Biped brings dance, that most physical of the arts, into the digital age, engaging the audience with its playful illusions. It's digital wizardry at its finest, and you don't need 3-D glasses--or opera glasses--to enjoy it. The Cunningham troupe performed Biped at Lincoln Center in New York City last week. It will tour Europe in the fall and return to Chicago, Washington and other...
...funeral. If he was able to transfer his hopes to Ted, it was not for long. The next summer brought Chappaquiddick, which seemed to doom Ted's chance for the White House. When Ted told his father about it, the ailing old man, already made speechless by a stroke, simply dropped his head to his chest. By November of that year, he was dead...
