The first concrete evidence that stuttering and a second speech disorder called spasmodic dysphonia are caused by biochemical abnormalities rather than by emotional disturbances was presented here Monday by University of Texas researchers. Stuttering affects one in every 100 people in the U.S. and spasmodic dysphonia, in which the larynx spasms to choke off words, affects perhaps a tenth as many. The discoveries, presented at a meeting of the American Assn.

Chromium is an essential trace mineral found in a variety of foods, including whole grains, cereals, spices (such as black pepper), broccoli, mushrooms, cheese, seafood and meat. In the body, it plays a role in metabolizing fats and carbohydrates and controlling blood levels of sugar. The body has a hard time absorbing chromium supplements in mineral form; it is absorbed more easily when it's bound to another molecule.

Oprah Winfrey recently informed the nation on "Good Morning America" that she "blew out her thyroid" at the end of last season because of stress. But that isn't exactly a medical term.

Whenever I hear about some amazing way to boost resting metabolism, my male-bovine-droppings detector goes berserk. Take the perennially popular one stating that 1 pound of muscle burns an extra 50 calories a day while at rest — so if you gain 10 pounds of muscle, your resting metabolic rate (RMR) soars by an extra 500 calories each day. Awesome! And also drivel. I'm more likely to believe bears use Porta-Potties and the pope is a Wiccan. Though its origins are uncertain, any number of fitness magazines have made the "50 calories per pound of muscle" statement.

The way Roman Gabriel tells it, the same characteristics that made him a great football player -- bullheadedness, combativeness, stick-to-itiveness -- served him less favorably in his personal life. Three times divorced, the greatest quarterback in Los Angeles Rams history is estranged from his daughter and four sons and says he has not seen two of his three grandchildren in years. The other, he has never met.

Cholesterol is thought to be crucial to normal metabolism, but a team at Quark Biotech Inc. of Fremont has produced apparently healthy mice that are cholesterol-free. The team reported in the current issue of Science that it removed a gene that carries out the final step in the natural production of cholesterol. The mice, however, are smaller than normal and show poorer growth characteristics.

The cluster of symptoms collectively known as a metabolic syndrome heighten the prospect that with age will come steep cognitive decline, a new study has found.  Researchers followed 7,087 French people over 65 for four years to see what factors were most clearly linked to losses in mental performance that fell short of dementia. Many seniors--including 15.8% of the sample--are diagnosed with metabolic syndrome , defined by these researchers as having two of the following five biomarkers: high blood pressure, a large waist circumference, a high  overall cholesterol reading , a particularly low score on HDL (or "good")

Horace Albert Barker, 93, UC Berkeley biochemist, who made significant studies in the function of vitamin B-12. Internationally respected, Barker in 1944 helped pioneer the use of isotopic tracers to synthesize sugar, sharing the Sugar Research Award from the National Academy of Sciences. In the 1950s, he moved into vitamin B-12 coenzyme chemistry and later into bacterial metabolism, fatty acid oxidation and carbohydrate transformations.

Just a few nights of bad sleep is enough to throw the body's metabolism into disarray, according to a new study published Monday in the journal Annals of Internal Medicine. The study shows that getting four hours of sleep a night for four nights made healthy people's bodies resistant to insulin - a condition that is a common precursor of weight gain, diabetes and other serious health problems. In a healthy body, when you take in sugar, insulin is released from the pancreas and travels throughout the body, signaling to cells that they should absorb some of that new glucose.
