...result could be a medical revolution. Until now, doctors haven't actually been fighting illnesses like cancer, stroke and heart disease. Instead they've been intervening at the level of symptoms--the last, visible step in a complex cascade of biochemical events. And they have done it largely by trial and error--finding new medicines in exotic plant extracts, for example, or looking for chemical compounds that resemble existing drugs. The process is so woefully inefficient that the drugs currently available target only 500 or so different proteins in the body...
...form of noninvasive, "black blood" magnetic-resonance-imaging technique allows doctors to detect problem spots in carotid arteries, the aorta and coronary arteries before patients develop symptoms of atherosclerosis or stroke. The high-resolution MRI blacks out blood flow, offering doctors a clear view of the blood vessels and allowing them to precisely measure the thickness of their walls. Though the black-blood technique still needs improvement, doctors hope the technology will eventually identify those at risk of heart attack long before they have...

...After decades of use as a decongestant and a weight-loss drug, a six-year study showed that the amphetamine-like stimulant phenyl-propanolamine (ppa) increases the risk of hemorrhagic stroke, especially in young women. The FDA subsequently deemed it unsafe and asked manufacturers to pull medications containing ppa off pharmacy shelves. ppa has been on the market since the mid-1930s, and consumers take 6 billion doses of it annually, in such products as Alka-Seltzer, Robitussin, Dexatrim and Tavist-D. Though ppa is widely used in many popular cold and diet pills, medications with the safer alternative pseudoephedrine...
