...interest in a topic long pigeonholed by science was spurred by a report that Eugenist Helen Spurway gave at University College in London. Among humans, she declared, virgin birth could not happen in the case of a hermaphrodite, who would not be self-fertile. However, parthenogenesis* might occur. This is the process by which an ovum begins to divide spontaneously, without having been fertilized by a sperm-perhaps after it has made up for the missing male chromosomes by a form of doubling. It is almost certain that the offspring of parthenogenesis would be a female, since the ovum contains...
Despite the high frequency of heart attacks, U.S. physicians still do not know just how often they occur, or with what results. In last week's A.M.A. Journal, Dr. Paul Dudley White appealed to all his colleagues to send him data of two kinds: 1) How many patients with acute coronary thrombosis did each physician treat in the 30-day period beginning Sept. 24, when the President had his attack? Details wanted include patient's sex and age, occupation, national origin, and whether the attack proved fatal in the first 24 hours or in one of the following...
...Lillehei, one of last week's Lasker Award winners (see above), told the American College of Surgeons that he had used the technique successfully on dogs, was about ready to try it on human patients. A section of coronary artery near the chest wall (in which most occlusions occur) is either opened, scraped clean and sewed up again, or is removed and replaced with a healthy length of artery. Operation time, in a "dry field" (using a heart-lung machine): half an hour...
Toynbee cited the responsibility of all religions to help human nature to cope with its innate sinfulness. "Within the last 5000 years, any change in human nature has been imperceptible," he said; "individuals differ in personality, but certain psychological types inevitably occur in the same proportions in all races...
...times. In the last 100 operations, he has had only six fatalities, all of them, he claims, from the normal deterioration of badly diseased hearts rather than from the operation itself. The principal purpose of the operation, says Beck, is to "take the steam out of successive attacks," which occur in 50% to 80% of coronary cases, with the chances of survival steadily decreasing. Said he to reporters: "Coronary surgery can't cure, but it ... prolongs the patient's life and makes him more comfortable. Nine of ten patients who receive the operation are back at work...
