Antioxidant Protects Islet Cells Used in Transplants for Diabetes

A synthetic antioxidant developed by researchers at National Jewish Medical and Research Center improves the survival of islet cells used in transplants for diabetes. The findings, reported in the August issue of the journal Diabetes by researchers at the University of Pittsburgh, could help overcome a significant drawback of the “Edmonton Protocol,” a promising treatment for diabetes. “The antioxidant neutralizes the harmful free radicals generated when islet cells are isolated from the pan

More quality, not more weight, may make vehicles safer, U-M researcher says

A University of Michigan physicist and a research scientist are questioning the belief that bigger and heavier vehicles are automatically safer than other cars and trucks. U-M physicist Marc Ross and Tom Wenzel, a research scientist at Lawrence Berkeley National Laboratory (LBNL), recently released a report which shows that vehicle quality is actually a better predictor of safety – both for the driver and for other drivers – than weight. The two will discuss their results at a briefi

ASU researcher puts recalled Firestone tires to good use

New field studies produce environment-friendly results An Arizona State University researcher is making good use of some of the 14 million Firestone tires that were recalled two years ago. The tires were used on Ford Explorers and recalled after reports of tread separation. How to dispose of all those used tires without causing serious environmental hazards once had state officials scratching their heads, but Civil and Environmental Engineering Professor Han Zhu believes has the answe

Archaeologists uncover 3700-year-old ’magical’ birth brick in Egypt

University of Pennsylvania Museum archaeologists have discovered a 3700-year-old “magical” birth brick inside the palatial residence of a Middle Kingdom mayor’s house just outside Abydos, in southern Egypt. The colorfully decorated mud birth brick–the first ever found–is one of a pair that would have been used to support a woman’s feet while squatting during actual childbirth. The birth brick, which measures 14 by 7 inches, was discovered during summer 2001 excavations directed b

Soy protein in the diet produces health benefits, regardless of isoflavone content

Many health advantages have been attributed to soy isoflavones, which are components of soy-protein foods, yet it is still unclear to what extent the isoflavones themselves are responsible for these benefits. In a new study published in the American Journal of Clinical Nutrition, Jenkins et al. compared the effects of a low-saturated fat control diet, and soy-protein diets with either a high or low isoflavone content in the context of their effects on risk for coronary artery disease. Compared with t

Wine drinkers have healthier lifestyles

People who consume alcohol in moderation are healthier, yet the relationship between alcoholic beverage preference and health benefit or risk has not been extensively investigated. In a new study published in the American Journal of Clinical Nutrition, Barefoot et. al. surveyed alcoholic beverage preference in a large and homogeneous group of highly educated upper-income Americans and found that beverage choice has implications beyond the relative physiological benefits of alcohol. Wine drinking has
