...afflicts up to 100,000 black Americans. A preliminary study in the New England Journal of Medicine suggests that butyrate, a widely used flavor enhancer, can overcome the basic cause of the disease. A genetic flaw leads the body to make abnormal hemoglobin, the blood protein that carries essential oxygen...
...first breakthrough occurred when neurologists realized that damage to the spinal cord continues to progress for about 48 hours after the initial accident. As the first nerve cells die, they release toxins that attack neighboring cells that have managed to survive. Some of these toxins are renegade oxygen molecules, called free radicals, that eat through cell membranes. The ensuing flood of biochemicals destroys even more nerve cells. The devastation spreads from the gray matter at the center of the cord to the white matter that surrounds it. Ironically, the body's response to injury only makes matters worse. The inflammation...
...this cascade of events could be interrupted, researchers reasoned, then further paralysis might be prevented. In 1990 Michael Bracken of Yale University and his colleagues showed that large doses of an inexpensive steroid, methylprednisolone, could do the job. Apparently, the drug attaches itself to the oxygen free radicals, preventing them from attacking vulnerable tissue. Bracken's study showed that if administered within eight hours of the accident, methylprednisolone could cut the amount of secondary damage in half, sometimes making the difference between the patient's being able to walk...
Hill helped clear up the confusion in the 1980s by carefully measuring the sulfur content of samples taken from the caverns. Her work proved that Carlsbad was carved not by carbonic acid but by sulfuric acid, produced by a reaction between oxygen dissolved in groundwater and hydrogen sulfide bubbling up from deep below the earth's surface. This highly toxic solution, which would have killed anyone present at the time, sculpted the many subterranean chambers at Carlsbad...
Lindsey's virtue is that he understands the centripetal nature of power -- that to get to the core of it, you have to almost disappear. Lindsey is everywhere and nowhere at the same time. "He's like oxygen," says Clinton strategist Paul Begala. "You can't see him, and you can't live without him." After years of his being at Clinton's side -- Lindsey was the presidential candidate's first traveling companion when the two trekked anonymously through airports, carrying their own bags -- there is practically nothing in print about him. He shuns interviews and does...
