...drug to treat not only depression but, with varying success, anxiety, nicotine addiction, body-image problems, bipolar disorder, psychosis and a host of other mental disorders.) While there's been less research on drugs that manipulate glutamate - perhaps because it can be modulated fairly easily with nonprescription amino acids like N-acetylcysteine - the new study suggests the neurotransmitter may play a key role not only in the rare condition of hair-pulling but also in other obsessive-compulsive problems...
...American College of Medical Genetics recommended uniform and broader screening for the entire catalog of conditions, including amino acid deficiencies, oxidative disorders and blood diseases such as sickle cell anemia. The March of Dimes and the American Academy of Pediatrics endorsed that recommendation, and lobbied states to legislate mandatory newborn screenings. That same year, a March of Dimes survey found that only 38% of babies were getting sufficiently screened, with at least 21 of the 29 available tests. "These are rare conditions, but they can be devastating and catastrophic if not detected," says Dr. Jennifer Howse, president of the March...
...Less studied, though, is the "genetic dillution effect," in which selective breeding to increase crop yield has led to declines in protein, amino acids, and as many as six minerals in one study of commercial broccoli grown in 1996 and '97 in South Carolina. Because nearly 90% of dry matter is carbohydrates, "when breeders select for high yield, they are, in effect, selecting mostly for high carbohydrate with no assurance that dozens of other nutrients and thousands of phytochemicals will all increase in proportion to yield...
...Disease (NIDDK). When Kahn began his research, it was known that insulin regulated blood sugar by binding to a specific receptor on cells. But Kahn’s lab was the first to discover the mechanism of this activation, which involves the addition of a phosphate molecule to the amino acid tyrosine...
...that front, at least, the British and American researchers may have good company. This week a separate team of researchers at the University of Texas announced they had found what may be the virus's "Achilles' heel" - a stretch of amino acids in the HIV envelope protein, which is necessary for the virus to attach to and infect host cells. Those amino acids, researchers say, could someday be a key therapeutic target and may help change the epidemic's course...
