Most of the excitement, however, is being generated by a group of vitamins -- C, E and beta carotene, the chemical parent of vitamin A -- that are known as antioxidants. These nutrients appear to be able to defuse the volatile toxic molecules, known as oxygen-free radicals, that are a byproduct of normal metabolism in cells. These molecules are also created in the body by exposure to sunlight, X rays, ozone, tobacco smoke, car exhaust and other environmental pollutants...
...pills. No heart attacks occurred among those in this group who received aspirin along with the beta carotene capsules. The Harvard researchers have begun a trial in 45,000 postmenopausal women to see if a similar effect occurs in women. Scientists speculate that the antioxidant helps prevent those nasty oxygen- free radicals from transforming LDL, the bad form of cholesterol, into an even more menacing artery clogger...
...Republican or Democratic--it has something to do with putting oxygen in the system, [which] is being suffocated," he said...
...vital gas being destroyed is a form of oxygen in which the molecules have three atoms instead of the normal two. That simple structure enables ozone to absorb ultraviolet radiation -- a process that is crucial to human health. UV rays can make the lens of the eye cloud up with cataracts, which bring on blindness if untreated. The radiation can cause mutations in DNA, leading to skin cancers, including the often deadly melanoma. Estimates released last week by the United Nations Environment Program predict a 26% rise in the incidence of nonmelanoma skin cancers worldwide if overall ozone levels drop...
...there for nearly a week, depriving all candidates of the chance to promote issue-oriented messages. Said former Democratic Party chairman John White: "Your first instinct is to think there's an opening, but other candidates were really disadvantaged by this trash too. It just sucked up all the oxygen in the room." Co-anchor Cathy Burnham of the state's leading television outlet, WMUR, wryly acknowledged that fact last week as she introduced a story on Senator Bob Kerrey's health-care ideas. "And now," she said, minutes into the newscast's political coverage...
