Comparable results have been obtained at Roswell Park Memorial Institute in Buffalo and Columbia-Presbyterian Medical Center in Manhattan. There, scientists use the reaction in an electric field between the patient's blood and serum from immunized rabbits to determine acid phosphatase levels...
...with the highest concentration of the fatty molecule in their bloodstreams run the greatest risk of atherosclerosis. This is the buildup of fibrous fatty plaques in the blood vessels and a precursor of heart disease-the leading cause of death in the U.S. Hence, the reduction of blood (or serum) cholesterol has become a prime goal of doctors and patients alike. Still, physicians have been puzzled by one observation: though some patients show a seemingly dangerous level of serum cholesterol, they somehow remain immune to coronary disease...
Play evened out during the second half, and with six minutes to go in the game Crimson back Sid Anderson scored on an extra-man situation off a set serum at the Brown 40 yard line. Anderson missed the conversion, leaving Harvard with a tenuous 4-3 advantage...
Hirumi concocted a novel brew that contained cells from the lung fluid of cows and serum from fetal calves. In effect, the formula fooled the parasite into acting as if it were in a natural host. Yet trypanosomes are exasperatingly fickle creatures. After they invade humans or cattle, they show a chameleon-like ability to change their protein coatings, whose molecular structure serves as a precise signal to the host's immune system for the production of specific antibodies against the invaders. As the immune system begins mustering appropriately shaped antibodies against the trypanosomes, the parasites change their coats...
...available a tailor-made microbe that cannot survive outside the laboratory and that cannot colonize or even live in the human intestinal tract. Nor is this the only indication that the bug would make a poor pathogen, or disease organism. Curtiss' handmade microbe will not survive in human serum-including that of cancer patients. It is also easily destroyed by common household detergents...
