...Alzheimer's patients. A short time later, four research teams zeroed in on the gene that encodes the recipe for making the protein. To their great surprise, they discovered that beta amyloid was a fragment of a much larger protein, which came to be known as the amyloid-precursor protein, or APP for short...
That same year, other research teams, including one led by Selkoe, created yet another stir. They zeroed in on the elusive enzymes that snip the beta-amyloid fragment from the precursor protein. "We had the paper, and now we had the scissors," says Selkoe. If he is right, one of those scissors, gamma secretase, may actually be the presenilin-1 protein. Whatever the true identity of gamma secretase turns out to be, pharmaceutical companies are rushing to develop drugs that block it. Bristol-Myers Squibb has already started safety tests of one such compound and hopes to expand its study...
...only shown no interest in renegotiating the pact to allow Washington to go ahead, it has also warned that if the U.S. withdraws from the treaty all other arms-control agreements are null and void. The reason for Moscow's hostility is that they see the system as a precursor of a larger umbrella that could eventually neutralize the deterrent value of Russia's own nuclear arsenal. And its fears are well grounded - while President Clinton is considering a limited system involving some 20 interceptors to guard against one or two missiles fired by "rogue states," candidate George W. Bush...
...fiber diets, while the other half went happily on their way eating their usual (read: low-fiber) foods. In a development that more than one researcher calls "shocking," members of the high-fiber group were no slower than their ostensibly less healthy counterparts to develop colorectal polyps - often a precursor to cancer...
...this one. They were bigger, older, rougher, more ska-core and punk. The floor then was not violent by Rage Against the Machine standards, catering more to the more gentle colliding of a skank pit. At that time, the opening band was Goldfinger, a light-hearted, prankish, oft-nude precursor to Blink-182. This time, the openers were not nearly as friendly. But the presence of the Suicide Machines did not scare off any of the teenage girls. Rather, the presence of the teenage girls lulled the Suicide Machines into a half-hearted set, ripping through their songs without many...
