...incubating ribonucleic acid (RNA) and protein from normal red cells with immature cells from victims of sickle-cell anemia, Cleveland's Dr. Austin S. Weisberger effected a crossover: the growing cells picked up the normal RNA and protein and, with it, the power to make normal hemoglobin. Cautiously, Dr. Weisberger hopes that similar methods may be developed for treating cancers of the blood...
...vast numbers in Africa. The disease got its name because the deoxygenated red cells in the veins lose their globular shape (they look normal in the arteries) and take a crescent or sickle form. The Pauling team found that this was because of a minute, submolecular abnormality in the hemoglobin...
With Conant, Pappenheimer had developed an improved method for measuring the oxidation potentials of hemoglobin. In addition, he had conducted research on cytochromes, iron-containing enzymes which are closely related to hemoglobin. Cytochromes fulfill an important function in the oxidative processes of metabolism in many organisms. Since diphtherial cytochrome is probably a derivative of coproporphyrin, the dual inhibiting effect of iron suggested that the toxin operates by "impersonating" cytochrome...
...have no time for such things as Winter Comps. I must construct ontological systems; I must synthesize ethyl alcohol from hemoglobin; I must proselytize the novels of Jane Austen...
...dealing with methemoglobinemia, in which poisoned red cells carry no oxygen, and other cells cannot deliver enough, to the tissues. Many chemicals can cause the condition, and Dr. Singley had no idea which was to blame. But the remedy is the same: methylene blue, given intravenously, restores hemoglobin to normal oxygen-bearing function. Dr. Singley tried it on both boys and they responded quickly, lost their weird bluish cast...
