In Print Photo by Graham Ramsay From Focus: Enzyme Mends Fibers that Give Stretch to Tissues In mammals, elastin fibers give mechanical flexibility to a variety of tissues, such as blood vessels, lungs, and the retina. Fiber damage can be life-threatening since there is no known way to rebuild elastin. But Tiansen Li (right), Xiaoqing Liu, and colleagues report that they have identified a natural enzyme that repairs elastin fibers in aging tissues. The finding may lead to a better understanding and therapeutic approach to aging-related diseases like macular degeneration.   Publications Online BBS Bulletin Focus HMI World HSTconnector MD-PhD Newsletter MedEd News Mentations On The Brain   Related Links InteliHealth Harvard Health Publications		Headlines Ratings of Teen-Rated Video Games Do Not Always Fully Describe Content Key Advance Reported in Regenerating Nerve Fibers Possible Mechanism for Link Between Diabetes and Alzheimer's Disease Discovered Research Clarifies How Alzheimer's Medicines May Reduce Interference with Learning and Memory Two Studies Examine Aspirin for Cancer Prevention Cancer Cells Can Compress Blood Vessels, Block Entry of Drugs Upcoming Milestone Symposium: Moving Drugs Forward: Reaching the Patient FDA Commissioner Mark McClellan and other presenters Tuesday, March 9 3:00-5:00 p.m.		Spotlight Nominations Sought for Annual Mentoring Awards The Office for Diversity and Community Partnership at HMS seeks nominations for two annual mentoring awards.
