...Gallo's quest for the cause of cancer began in childhood. As a boy of 14, in Waterbury, Conn., he watched his younger sister die of leukemia. The memory is still vivid: "She was an emaciated, jaundiced child with a mouth full of blood." His sister's pathologist became a family friend, and Gallo grew up accompanying him to his lab. In 1965 he joined the NCI and began the hunt for his sister's killer...
University of Minnesota plant pathologist Chester J. Mirocha said that Meselson's findings were irrelevant to the whole debate, because the samples of leaves containing mycotoxins did not have the yellow spots which resemble bee feces...
...major villain in this epidemic. It has not been easy. Cholesterol is, after all, only one piece in a large puzzle that also includes obesity, high blood pressure, smoking, stress and lack of exercise. All of these play their part in heart disease "like members of an orchestra," explains Pathologist Richard Minick of the New York Hospital-Cornell Medical Center...
...suspicious about cholesterol, particularly the cholesterol in diet, when they looked inside the diseased arteries of heart attack victims. There, instead of smooth, supple vessels, they saw what looked like brittle, old pipes, clogged and hardened by deposits of cholesterol-the condition now known as atherosclerosis. In 1913, Russian Pathologist Nikolai Anitschkow showed that he could produce similar deposits, or plaques, in the arteries of rabbits just by feeding them a diet rich in cholesterol. Subsequent research further supported the connection between diet and cardio-vascular disease. Epidemiologist Ancel Keys conducted a landmark study in seven nations beginning...
...widely accepted explanation is the so-called injury theory, propounded by Russell Ross at the University of Washington in Seattle. According to Ross, the disease begins with damage to the thin layer of cells, or endothelium, that forms the protective lining of the arteries. In some cases, says Seattle Pathologist Earl Benditt, the lining may be harmed by viral infection. He has detected the presence of herpes virus in about 8% of atherosclerotic tissue samples. Damage can also result from high blood pressure, which forces blood to strike the artery wall with unusual force; from chemical derivatives of cigarette smoke...
