Now, scientists have found new ways of obtaining precise and comprehensive data from x-ray computer tomography. In the project BIO-CT-EXPLOIT, an international team of mathematicians, physicists, and  engineers   figured out new ways to extract valuable information from the data obtained in CT scans. The research project has led to new computer codes for medical applications. In future, they will be used for bone implants, surgery, and tissue engineering. http://medicalxpress.com/news/2012-01-ct-scan.html Other Mon, 30 Jan 2012 08:08:04 EST news247133269 Breast reconstruction surgery will become both safer and more realistic thanks to research led by Queensland University of Technology (QUT) in Brisbane, Australia. http://medicalxpress.com/news/2011-12-advances-breast-reconstruction.html Other Tue, 06 Dec 2011 09:38:46 EST news242386716 A team of scientists from Worcester Polytechnic Institute (WPI) and CellThera, a private company located in WPI's Life Sciences and Bioengineering Center, have regenerated functional muscle tissue in mice, opening the door for a new clinical therapy to treat people who suffer major muscle trauma. http://medicalxpress.com/news/2011-11-body-rebuilding-regenerate-muscle-mice.html Medical research Tue, 29 Nov 2011 13:28:23 EST news241795693 (Medical Xpress) -- During the conflicts in Iraq and Afghanistan, blast injuries resulting from improvised explosive devices, or IEDs, and roadsides bombs took countless lives and left thousands of soldiers who managed to survive with devastating injuries. http://medicalxpress.com/news/2011-11-platelet-rich-plasma-chronic-wounds-veterans.html Medical research Thu, 10 Nov 2011 08:50:01 EST news240136247 (Medical Xpress) -- Lasers have been used to fabricate tiny scaffolds to be used as delivery vehicles to drop cells off at damaged locations and help treat diseases such as Alzheimer’s and Parkinson’s. http://medicalxpress.com/news/2011-09-lasers-path-neuron-regeneration.html Medical research Wed, 21 Sep 2011 08:25:19 EST news235812205 Researchers have been working at growing tissue and organs in the laboratory for a long time.

To improve that knowledge, Brown University researchers have developed a simple and reliable system for measuring the power that cells employ to assemble into three-dimensional tissue. The research appears online the week of April 11 in Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2011-04-tissue-biomaterials.html Medical research Mon, 11 Apr 2011 16:07:17 EST news221756827
