...lipoproteins). LDLs are called "bad" cholesterol because an excess of cholesterol carried by them can lead to the buildup of harmful deposits in the arteries. The other cholesterol carriers, known as HDLs (for high-density lipoproteins), are considered "good" because, far from being killers, they may actually play a vital role in preventing heart disease. They seem to act like biological vacuum cleaners, sucking up excess cholesterol in the bloodstream. It is because the 50-odd Cincinnati families possess unusually high levels of HDL that they are believed to have such a resilient blood chemistry -- and such long lives...
Portable analyzers, though, cannot calculate LDL and HDL levels. Even many laboratories have been unable to give consistently accurate counts of HDL. Yet that figure may be the most vital statistic of all in evaluating cardiovascular health in otherwise moderate- or low-risk individuals. Says Dr. Bruce Gordon, associate professor of medicine at Manhattan's Rogosin Institute: "There are a sizable number of people who would be inappropriately treated unless their HDL levels were taken into account...
Just how HDL plays its apparently vital role in ridding the body of excess cholesterol is not entirely clear. The substance is, after all, only one element in an alphabet soup of particles that make up the so-called lipid transport system, which moves cholesterol through the bloodstream. Though individual cells can make their own cholesterol, much of their supply comes from the bloodstream, arriving from the liver aboard macromolecular ferryboats, known as very-low-density lipoproteins, or VLDLs. These carrier particles are loaded in the liver with cholesterol and dietary fats known as triglycerides, which are used by cells...
Lawyers call threats by defense attorneys to disclose classified information "graymail." To laymen, it looks suspiciously close to blackmail since it forces the prosecution to make a choice: let the secrets be revealed or drop the relevant charges. North has insisted that more than 3,500 classified documents are vital to his defense. Special prosecutor Lawrence Walsh wants to use about 400 secret papers, from which a special interagency group made numerous deletions to protect national security. North's lawyers have objected to nearly all these exclusions. If the judge decides the deleted information is necessary for North's defense...
