...effects to amphetamines but is sold over-the-counter, can also be dangerous when taken before exercise, and was linked to the death of Baltimore Orioles pitcher Steve Bechler earlier this year. One Orioles team doctor said, “It makes the heart beat faster, the blood vessels constrict. That poor kid cooked to death from the inside...
...literary conventions do constrict the writing on occasion, beginning with the rigid stereotypes of each character. The audience feels somewhat beaten over the head with repetitions of “you’re so dull” and “you’re so crazy” between two opposing characters in a formulaic character foil. The sullen girl’s continuous moping and the irrepressible cheeriness of her friend become overwhelming about ten minutes into the production...
...Soyinka, winner of the 1986 Nobel Prize for Literature, has championed "The Last Summer of Reason," writing a foreword for the new book. "We're really in a season of fundamentalist insanity in many religions," Soyinka told us. "There's a real escalation of intolerance, of the will to constrict the mind. Many people outside have been unaware of the enormity of the killings that have been taking place in Algeria, for instance, in the name of religious purity. So a book like Djaout's, which is a very pointed allegory, is something that I think is required at this...
...first, the effects of serotonin seemed confined to the body alone: it was found to trigger contractions in the muscles and intestines and to regulate blood pressure by forcing blood vessels to constrict. But experiments at the National Institutes of Health in the 1950s revealed that compounds that depressed serotonin levels depressed patients as well. Not long after, researchers found two more clues to the serotonin-depression connection. The first was that reserpine, an anti-blood-pressure medicine that depresses serotonin levels, can sometimes trigger depression. The second came from iproniazid, originally developed as an anti-tuberculosis agent. The medicine...
BETTER DRUGS Researchers have long known that a brain chemical called serotonin plays an important role in triggering migraine headaches. For reasons that are still unclear, serotonin sometimes floods the blood vessels of the brain, causing them to constrict. The body then overreacts, sending serotonin levels plummeting and forcing the blood vessels to expand to several times their normal size. This cycle of contraction and expansion results in the headache's characteristic throbbing pain. In 1993 Glaxo introduced a drug called Imitrex that allowed doctors for the first time to prescribe something that was specifically designed to interrupt the cycle...
