(PhysOrg.com) -- Scientists have extracted organically preserved muscle tissue from an 18 million years old salamander fossil. The discovery by researchers from University College Dublin, the UK and Spain, reported in the Proceedings of the Royal Society B shows that soft tissue can be preserved under a broader set of fossil conditions than previously known. http://www.physorg.com/news176660912.html Other Sciences Thu, 05 Nov 2009 17:20:01 EST news176660912 Limb-sparing surgery, which has been taking the place of amputation for bone and soft tissue sarcomas of the lower limb in recent years, may not provide much or even any additional benefit to patients according to a new review. The analysis, published in the September 15, 2009 issue of Cancer indicates that patients and physicians should rethink the pros and cons of limb-sparing surgery and amputation. http://www.physorg.com/news169104146.html Medicine & Health Mon, 10 Aug 2009 06:23:22 EST news169104146 Canadian scientists at the University of Alberta's Cross Cancer Institute are developing a new technology that integrates two existing medical devices -- medical linear accelerators, or "linacs," which produce powerful X-rays for treating cancer, and magnetic resonance imagers (MRIs), which are widely used to image tumors in the human body. http://www.physorg.com/news167934943.html Medicine & Health Mon, 27 Jul 2009 18:00:04 EST news167934943 Researchers at The University of Nottingham are hoping to find out if inflammation of the knee could be an early sign of osteoarthritis - a condition which leads to pain, stiffness, swelling and disability. http://www.physorg.com/news167568303.html Medicine & Health Thu, 23 Jul 2009 11:45:45 EST news167568303 (PhysOrg.com) -- For modern implants and the growth of artificial tissue and organs, it is important to generate materials with characteristics that closely emulate nature. http://www.physorg.com/news161598692.html Nanotechnology Fri, 15 May 2009 09:33:56 EST news161598692 Oncologists often have to wait months before they can determine whether a treatment is working. Now, using a non-invasive method, researchers at UCLA's Jonsson Comprehensive Cancer Center have shown that they can determine after a single cycle of chemotherapy whether the toxic drugs are killing the cancer or not. http://www.physorg.com/news158951404.html Medicine & Health Tue, 14 Apr 2009 18:10:40 EST news158951404 Paleontologists in 2005 hailed research that apparently showed that soft, pliable tissues had been recovered from dissolved dinosaur bones, a major finding that would substantially widen the known range of preserved biomolecules. http://www.physorg.com/news136613903.html Biology Wed, 30 Jul 2008 05:18:23 EST news136613903
