A team of European researchers says hair grays with age as follicles become bleached first gray, and then white, from within. The researchers closely examined cell cultures of human hair follicles and found in the absence of the enzyme catalase, the hydrogen peroxide naturally produced in hair cells stops being broken down into water and oxygen. Also, hair follicles could not repair the damage caused by the accumulating hydrogen peroxide because of low levels of enzymes MSR A and B. High...

Two presentations during the American Society of Nephrology's Renal Week demonstrated that frequently monitoring hemoglobin during hemodialysis will provide physicians with trending information that may reduce hemoglobin variability. The study demonstrated increased time-in-target range for hemoglobin in end-stage renal disease patients. The study suggests that increased frequency of hemoglobin monitoring may contribute to more accurate dosing for anti-anemia medication (e.g., erythropoietin...

By Shelley, Suzanne ENVIRONMENTAL Tetra-amido macrocyclic ligands (TAMLs) are environmentally friendly catalysts with a host of pollution- reduction and clean-up applications, and are a prime example of green chemistry. Terry Collins, professor of chemistry and director of the Center for Green Science at Carnegie Mellon Univ., created the catalysts and now believes that small-molecule catalysts have the potential to be even more effective than previously proven. The oxidation catalysts...

Bristol-Myers Squibb Company and AstraZeneca have presented promising results from a 24-week Phase III study of saxagliptin, an investigational DPP-4 inhibitor in development for the treatment of type 2 diabetes. Results from a 24-week Phase III study have demonstrated that saxagliptin, when used in combination with metformin as an initial therapy, produced reductions across all key measures of glucose control studied (glycosylated hemoglobin level (A1C), fasting plasma glucose and...

Instruments falsely report anoxia in affected peopleScientists at the University of Bonn have discovered a new rare type of hemoglobin. Hemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes color. The new hemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. After examining two patients, the scientists now...

TURIN (Reuters) - Eight Nordic skiers at the Winter Olympics have been suspended for five days after tests showed they had an abnormally high red blood cell count, the International Ski Federation (FIS) said on Friday. Sean Crooks (Canada), Sergey Dalidovich (Belarus), Jean Marc Gaillard (France), Alexsandr Latzukin (Belarus), Natalia Matveeva (Russia), Kikkan Randall (U.S.), Evi Sachenbacher (Germany) and Leif Zimmermann (U.S.) were shown to have abnormally high hemoglobin values,...

Inhaling a small dose of nitric oxide gas may one day help sickle cell patients avoid pain crises and live healthier lives, researchers say. Nitric oxide may help normalize a sickle cell patient's hemoglobin by restoring the natural charge and shape to the oxygen-carrying component of red blood cells, Medical College of Georgia researchers have found. "Hemoglobin S plus nitric oxide behaves much like normal adult hemoglobin, which does not sickle," says Dr. C. Alvin Head, chair of the Medical...
