But researchers are quietly moving forward finding new miracles these incredible cells can perform. Out of my own curiosity--in 2008 I had bioprosthetic valve replacement surgery--I decided to see where they were on fixing hearts with stem cells.Found this CBS news story from last June about a guy who's taking part in a clinical http://www.biomednews.org/2010/03/stem-cells-new-source-for-heart-repairs.htmlnoreply@blogger.com (Barbara Payne)0tag:blogger.com,1999:blog-7726830.post-4072915706972072140Wed, 03 Feb 2010 10:27:00 +00002010-02-03T05:00:08.507-06:00Image via WikipediaA doctor who specializes in treating aneurysms has been searching for a way to prevent some patients--certain genotypes are more susceptible--from suffering strokes within days after initial treatments.

They're telling us again how good for us red wine is. This time a benefit has been found to start even before wine's antioxidant protective qualities have had a chance to kick in.
