Every year some 400,000 Americans undergo bypass surgery to shunt the flow of blood around blocked arteries in their heart; 500,000 other patients opt for a different procedure called angioplasty, which clears a channel through the bottlenecks with thin, inflatable balloons. Most people who have these operations get what they so desperately want--a second chance at life. But the results are usually temporary. After a few years the bypass graft or the reopened artery becomes clogged with new deposits, which often require a second round of treatment. For an estimated 1 in 10 patients, the heart becomes...
Already, 1,000 patients have received the experimental therapy at 50 different medical centers. In most cases the treatment was part of a conventional bypass or angioplasty. But the preliminary results were so encouraging that doctors have started offering the new therapy to patients who are too sick to undergo any more conventional operations. There are still many unanswered questions, and some patients have died (although researchers insist their deaths did not occur as a consequence of the treatment). Yet if the new therapy lives up to its promise, hundreds of thousands of men and women with heart disease will...
...that can do just that and tried it out on 104 volunteers. The results of this study, having been withdrawn once, will probably never be published in a scientific journal. Because Zicam is marketed as a homeopathic remedy, however, the Food and Drug Administration doesn't require it to undergo rigorous testing...
...there will be drugs to trip up a cell at each of the steps it takes on the path to malignancy. A patient with lung cancer, say, might undergo gene therapy, breathing in genetically altered cold viruses that don't cause infection but instead act as miniature delivery vans carrying copies of the p53 gene. Good copies of this gene, which is mutated in many cancers, can force some cancer cells to commit suicide. The effects of p53 could be bolstered with antibodies that slow tumors by attaching to the surface of cancer cells and gumming up their ability...
...Young Universe theory has not, and will not, undergo the trying scientific scrutiny that evolution has been subjected to for years, largely because its proponents understand that it would fail to pass a test of logic and the scientific method. Whereas evolution has years of documented research proving convincingly that it is a valid theory, there is no scientific evidence to support creationism and little to support the "Young Universe" theory. Instead, the changes in educational standards instituted by the Board will have long-term detrimental effects on the quality of education in Kansas public schools and will only harm...
