(PhysOrg.com) -- In research that could open new avenues of investigation in the prevention and treatment of fractures, in bone regeneration and tissue engineering, scientists from Yale School of Medicine have found that a combination of bone marrow aspiration followed by treatment with anabolic parathyroid hormone (PTH) greatly boosted bone regeneration in localized areas in rats. The study appears online in the Journal of Bone and Mineral Research. http://www.physorg.com/news180721494.html Medicine & Health Tue, 22 Dec 2009 16:42:14 EST news180721494 (PhysOrg.com) -- Nature and its bottom-up processes for creating robust and responsive materials are inspiring new generations of synthetic materials and creative design. http://www.physorg.com/news179137286.html Biology Fri, 04 Dec 2009 08:22:22 EST news179137286 Researchers in Pennsylvania are reporting for the first time that nanoparticles 1/5,000 the diameter of a human hair encapsulating an experimental anticancer agent, kill human melanoma and drug-resistant breast cancer cells growing in laboratory cultures. The discovery could lead to the development of a new generation of anti-cancer drugs that are safer and more effective than conventional chemotherapy agents, the scientists suggest. The research is scheduled for the Dec. 10 issue of ACS' Nano Letters. http://www.physorg.com/news148573402.html Nanotechnology Mon, 15 Dec 2008 14:23:22 EST news148573402 A nontoxic nanoparticle developed by Penn State researchers is proving to be an all-around effective delivery system for both therapeutic drugs and the fluorescent dyes that can track their delivery. http://www.physorg.com/news146243225.html Nanotechnology Tue, 18 Nov 2008 15:07:05 EST news146243225 (PhysOrg.com) -- Medical researchers are looking at any number of new methods to get drugs to specific locations in the body. Some methods are efficient but less safe, while others are safe but often fail to deliver. http://www.physorg.com/news145939852.html Nanotechnology Sat, 15 Nov 2008 02:50:52 EST news145939852
