Explosive Expansion. While they assessed the Russian information, Western scientists continued to interpret Luna 9's pictures. London University Astronomer Gilbert Fiedler called attention to lines in some of the pictures that might be edges of an ancient lava flow; he agreed with the Russians and many American scientists that the porous surface resulted from the explosive expansion of gases in the lava as it emerged onto the moon's airless surface...
...suffer from coronary artery disease, fewer than 10 million have their problem neatly confined to a plug of fatty or chalky material in a single artery -what doctors call "segmental disease." The majority have a diffuse disease involving several artery branches, vastly complicating all efforts to boost blood flow to the oxygen-starved heart muscle. Because there is as yet no proof that medical treatment with diet, drugs, exercise and control of weight and blood pressure does much good, Santa Monica's Dr. James A. Mc-Eachen told the American College of Cardiology, countless victims may eventually turn...
Bailey (TIME cover, March 25, 1957); now, says McEachen, the reaming-out (see diagram), which he does in the di rection opposite to that of the blood flow to reduce the risk of clotting, may have to be combined with the graft of a patch into the side of the diseased artery to restore its full bore. Under any circumstances, he said, the heart-lung machine is needed during the operation, and the surgeon has to use "microsurgical instruments, magnifying lenses, tiny sutures and great care." Of six Santa Monica patients followed for up to three years, five have derived...
...type of coronary disease, most cardiac surgeons base their work on a technique first used in 1950 by Montreal's pioneering Dr. Arthur M. Vine-berg. The left internal mammary artery, which is not very important in man, is implanted in the heart wall so that its blood flow may reinforce the coronaries. One internal mammary is big enough to carry an adequate blood supply for the entire left ventricle (the heart's main pumping chamber), and if the blood still does not reach all the starved areas, the right mammary artery can be used to supply...
High tides and heavy storms also cause flooding problems in the Cambridge-Boston area. Engineers cannot let the flow through the dam during the hours of high tides for fear of a water backrush. A flow of storm into the river at that time causes overflowing...
