...malignant cells, he has found, do not grow faster than normal cells. Nor do they have more growth energy. Nor are they necessarily diseased. They do, however, differ from normal cells in their physiological properties. Chief difference is the fact that they use nitrogen. The nitrogen they get from proteins or protein-split products. And of those the body has an unlimited store. That is why cancer cells can multiply (not grow in size) so rapidly...
...question of whether man shall ever be able to reproduce living light, which is at least twice as efficient as best artificial light, becomes the question whether chemists will ever be able to synthesize the protein luciferin. Dr. Harvey thought that "that will come in the future. We now synthesize fats, sugars, and some of the polypetides." Luciferin seems to be either a peptone or a proteose...
...nose and red eyes took a woe-begone seat in Dr. Grafton Tyler Brown's consultation room, in Washington. Dr. Brown eyed the patient diagnostically and stated: "You have hayfever." The stuffy head snufflingly: "Yes!!" Dr. Brown scraped the man's skin and tested it with every protein he suspected might have caused the hayfever. One protein reacted positively. Stated Dr. Brown: "You have a parrot in your home." Patient snuffled: "Yes." Dr. Brown: "Get rid of the parrot." The patient did so and never after had stuffy head, running nose, red eyes. The irritating protein was dust...
Probing more basically into the world wheat situation, Grand Meunier Vilgrain declared that French wheat kernels have been of poor quality since the War, and do not now contain a sufficient proportion of protein and gluten. This effect has been wrought by the post War shortage of man power on the farms, which has induced land owners to plant a species of wheat seeds giving a greater harvest with less care, but an inferior grade of wheat. For this reason the Grands Moulins de Paris bought 10,000,000 bushels of prime U. S. wheat for milling, last year...
Mummy Germs: Tubercular bacilli found in Egyptian mummies are just like those that infest human bodies today. The characteristics of living matter change only as environment changes. Primitive living molecules were and are proteins. There is no life save in protein. The first evidence of life is metabolism or trading in energy. Biologists say the origin of species is due to changes in the formation of cells. In fact it is due to changes in types of proteins based on differences in environment.?Dr. Victor C. Vaughan, National Research Council...
