A small group of patients with a common heart defect who were treated for varicose veins with an injectable microfoam experienced no neurological, visual or cardiac changes as a result of the treatment, according to preliminary results from a phase II trial.   view more (2008-03-17)

Henry Ford Hospital to study effectiveness of a new procedure that may help emphysema suffers
Researchers at Henry Ford Hospital today announced the start of the EASE (Exhale Airway Stents for Emphysema) Trial, an international, multi-center clinical trial to explore an investigational treatment that may offer a significant new option for those suffering with advanced emphysema.   view more (2008-03-13)

Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't.   view more (2008-03-12)

New techniques improve imaging quality, not diagnosis of Barrett's esophagus
Novel techniques to improve the quality of imaging are helping doctors get a better look at esophageal conditions such as Barrett's esophagus (BE), but they do not necessarily improve the diagnosis or physician agreement on images, according to a study published this month in Gastroenterology, the... view more (2008-03-12)
