Last week researchers at the University of Texas Southwestern Medical Center at Dallas announced a promising new way of increasing bone density that seems to reverse the effects of spinal osteoporosis. The treatment relies on sodium fluoride, the chemical used by dentists to strengthen teeth and in toothpaste to prevent cavities. When the drug was tested years ago as a treatment for osteoporosis, it produced severe side effects like stomach bleeding, and while the fluoride caused bones to thicken, they were still easily broken. But the Texas researchers tried giving patients slow-dissolving fluoride pills that released the drug only...
...becoming particles of LDL. The LDLs are then pulled out of the bloodstream by special protein receptors on the surface of cells. "These receptors reach out and grab cholesterol like a first baseman catching a ball thrown by a shortstop," says Dr. Michael Brown of the University of Texas Southwestern Medical Center, who, with his colleague Dr. Joseph Goldstein, won a Nobel Prize in 1985 for discovering LDL receptors. What happens to excess LDLs that are not taken up by cells? Under normal conditions, these are swept by the bloodstream through the liver, where they are captured by cell receptors...
...living habits are major contributors to heart disease. Scientists are convinced that well- designed prevention programs can cut the incidence of heart disease in the U.S. by two-thirds, perhaps even more. "Twenty years from now," says Dr. Scott Grundy, a nutrition researcher at the University of Texas Southwestern Medical Center at Dallas, "I expect to see a dramatic reduction in heart attacks...
Gorbachev's remarks contrasted with comments he had made just before the extraordinary session in Tallinn. During a speech at the southwestern agricultural center of Oryol, he acknowledged that his policies of glasnost had "brought to light a lot of problems . . . in interethnic relations."

But in the Cincinnati suburb of South Greenhills, some ten miles east of the Department of Energy's Fernald nuclear weapons plant, Charles Zinser, 38, was preoccupied, unmindful of the glorious surroundings. Zinser recalled how beginning in 1984 he had rented a vegetable garden near the plant. He often took his two young sons along as he worked. Two years later, both were found to have cancer. Samuel, then eight, had leukemia, and Louis, two, had part of a leg amputated...
