...research has come to a virtual halt, causing the U.S. to fall far behind other countries in developing new techniques. Methods available overseas but not in the U.S. include an injection that provides two months of protection and a skin implant that can release a contraceptive hormone into the bloodstream for up to five years...
...enzyme is crucial in curbing intoxication. When a shot of vodka or a beer is swallowed, it travels to the stomach and then to the intestine, where it passes through the organ's wall into the bloodstream. Once there it circulates to the brain, where it finally exerts its inebriating effect. Alcohol dehydrogenase breaks down spirits in the stomach, reducing the amount of pure alcohol that enters the bloodstream about 20%; the rest is eventually metabolized by similar enzymes in the liver...
...freedom from unnecessary red tape. Too many controls, he declared, could "constipate" the financial exchanges. That is the kind of attitude that has brought the system to its current state, in which drug money freely mingles with the life force of the world economy, like a virus in the bloodstream...
...panoply of risk factors, which also include heredity, smoking, high blood pressure and obesity. Even the idea that cholesterol is "bad" is seriously flawed, since the chemical is produced naturally in the body and is vital to the functioning of human cells. It is carried in the bloodstream by two types of molecules: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Too much LDL is harmful because it contributes to the accumulation of fatty deposits that block arteries, but large amounts of HDL are thought to be beneficial because they seem to help clean the blood vessels. Moore correctly...
...brain degeneration or is a by-product is not clear. But if the beta amyloid is the cause, then the Boston research could represent a turning point. The study suggests that the suspect chemical may be produced in one or more tissues outside the brain, circulate in the bloodstream and enter various other tissues. But damage seems to occur only when the beta amyloid is deposited in certain regions of the brain important to memory and intellect. If that is true, then a way might be found to block the delivery of the protein to the brain. That could slow...
