...experiment involved 21 men between the ages of 61 and 81 who had negligible levels of HGH. Twelve of the men gave themselves injections of synthetic hormone three times a week for six months; the others received no treatment. All the subjects followed a diet of about 15% protein, 50% carbohydrates and 35% fat but were told not to alter their life-styles, including the amount they smoked and drank...
...nutritional value of meat has been greatly exaggerated," said Maynard S. Clark of the Farm Animal Reform Movement. "The protein value of meat is approximately that of soybeans, lentils, nuts and the seeds. The four nutritional advantages of meat products--protein, calcium, iron and vitamin B-12--are readily available in a diverse diet from plant foods...
...actions of neuropeptides, molecular messengers that travel through the body linking the nervous, immune and endocrine systems. In the 1970s neuropharmacologist Candace Pert at the National Institute of Mental Health found that these peptides bind to receptors on a cell, beginning a cascade of biomedical effects, including protein synthesis and cell division. "It's like ringing a doorbell. All kinds of reactions happen inside," says Pert. "The whole metabolism of a cell can be altered." Because their activity fluctuates with emotional states of mind, Pert refers to these peptides as "the biochemical units of emotion." Exhilaration triggers certain neuropeptides; depression...
...dogs are well protected too. Bred by Steger, they are hybrids of Siberian husky, malamute and timber wolf. They are fed a high-protein diet and are outfitted with jackets and booties. Even so, the journey has been brutal for the animals. Fifteen of them became so exhausted that they had to be airlifted out temporarily to Patriot Hills. One of Steger's favorites, an eight-year-old named Tim who had gone with him to the North Pole, died during the blizzard...
Patients received injections of interferon, a natural infection-fighting protein that can be artificially produced by genetically altered bacteria. One drawback: most of the patients who improved suffered a relapse when the injections ended. Doctors think the problem may be resolved by giving interferon for longer periods or in higher doses. Says Dr. Saul Krugman of New York University medical school: "There's no question that it is very promising...
