Anti-bacterial additive widespread in U.S. waterways
Many rivers and streams in the United States are believed to contain a toxic antimicrobial chemical whose environmental fate was never thoroughly scrutinized despite large-scale production and usage for almost half a century, according to an analysis conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. The chemical, triclocarban, has been widely used for decades in hand soaps and other cleaning products, but rarely was monitored for or detected in the environment. The new findings suggest that triclocarban contamination is greatly underreported. The study is published in the current online edition of Environmental Science & Technology, a peer-reviewed journal of the American Chemical Society.  more

Rebuilding wounded veterans: Annual review of limb loss & prosthetics research
The FDA has approved a partial artificial heart that keeps people alive in the hospital while they wait for a heart transplant. The SynCardia CardioWest Temporary Total Artificial Heart is intended to be a "bridge to transplant" for people who don't respond to other treatments and who could die from non-reversible biventricular heart failure, a condition in which both the left and right sides of the heart are not functioning properly. The device, cleared for marketing in October 2004, is the first of its kind authorized to be sold in the United States  more

Protein adiponectin appears protective against heart disease
Reduced blood concentrations of a protein called adiponectin appear to indicate a significant risk of cardiovascular disease in one of the first studies to focus on risk of the disorder among patients with diabetes mellitus type 1, previously known as juvenile diabetes. Recent studies suggest that adiponectin, a protein specific to fat tissue, is involved in obesity, diabetes and heart disease. more

Molecule predicts colon cancer patient survival
Harvard researchers have examined the factors that help spur the progression of colorectal cancer and identified the integrin [alpha]v[beta]6 as an important risk factor for development of early-stage disease. They further demonstrate that detection of high levels of this molecule is able to predict patient survival for colorectal cancer, a disease that kills over 55, 000 Americans each year. The study will appear online on January 20 in advance of publication in the February 1 print edition of the Journal of Clinical Investigation.  more
