Researchers have developed an improved version of an enzyme that degrades the dense scar tissue that forms when the central nervous system is damaged. By digesting the tissue that blocks re-growth of damaged nerves, the improved enzyme - and new system for delivering it - could facilitate recovery from serious central nervous system injuries. http://www.physorg.com/news176398485.html Medicine & Health Mon, 02 Nov 2009 15:35:23 EST news176398485 Mother Nature has provided the lizard with a unique ability to regrow body tissue that is damaged or torn ― if its tail is pulled off, it grows right back. She has not been quite so generous with human beings. But we might be able to come close, thanks to new research from Tel Aviv University. http://www.physorg.com/news175177923.html Biology Mon, 19 Oct 2009 13:32:43 EST news175177923 Scientists are developing new scaffolding technology which could be used to grow tissues such as skin, nerves and cartilage using 3D spaghetti-like structures. Their research is highlighted in the latest issue of Business, the quarterly highlights magazine of the Biotechnology and Biological Sciences Research Council. http://www.physorg.com/news174906941.html Chemistry Fri, 16 Oct 2009 10:30:01 EST news174906941 Researchers have fresh insight into an evolutionarily ancient way that cells cope when oxygen levels decline, according to a new study in the October 7th issue of Cell Metabolism. In studies of cells taken from the lining of human pulmonary arteries, they show that a microRNA - a tiny bit of RNA that regulates the activity of particular genes and thus the availability of certain proteins - allows cells to shift their metabolic gears, in a process known as the Pasteur effect. http://www.physorg.com/news174050396.html Medicine & Health Tue, 06 Oct 2009 12:40:01 EST news174050396 (PhysOrg.com) -- Tracking down new active agents for cancer or malaria treatment could soon become easier - thanks to a computer program with which researchers from the Max Planck Institute of Molecular Physiology in Dortmund aim to facilitate the search for suitable pharmaceutical substances. The program, which is called Scaffold Hunter, acts as a tool for navigating chemical space. http://www.physorg.com/news167924736.html Chemistry Mon, 27 Jul 2009 15:30:02 EST news167924736 (PhysOrg.com) -- MIT engineers and colleagues have built a new tissue scaffold that can stimulate bone and cartilage growth when transplanted into the knees and other joints. http://www.physorg.com/news161257258.html Medicine & Health Mon, 11 May 2009 10:41:38 EST news161257258 (PhysOrg.com) -- As a high school sophomore, Asad Moten read a news story about engineering new organs for patients waiting for a transplant, and decided to start his own tissue-engineering project. http://www.physorg.com/news155489423.html Chemistry Thu, 05 Mar 2009 15:32:25 EST news155489423 Broken hearts could one day be mended using a novel scaffold developed by MIT researchers and colleagues. http://www.physorg.com/news144852736.html Medicine & Health Sun, 02 Nov 2008 12:52:16 EST news144852736
