This helps explain why some diets work better for some people than others, and su Wed, 28 Jul 2010 11:18:16 PDT http://generef.com/newsstory.rss.html?pid=82534 http://generef.com/newsstory.rss.html?pid=82534 Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease.
