Researchers at the International Center for Materials Nanoarchitectonics (MANA) and Tokyo Medical and Dental University have developed a coating method which accelerates bonding with bone by 3 times. http://medicalxpress.com/news/2013-05-coating-method-bonding-bone.html Medical research Mon, 27 May 2013 08:27:41 EST news288862048 Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs? http://medicalxpress.com/news/2013-05-source-kidneys-transplant.html Medical research Mon, 20 May 2013 16:20:04 EST news288284721 Elderly or people with osteoporosis, smokers, diabetics or people who have had cancer are sometimes not eligible to receive dental implants as their bones are unable to correctly integrate the new prostheses which replace the root. Researchers at the Universitat Jaume I (UJI) in Castellón have developed an implant coating with a novel biodegradable material aimed at people with bone deficit. It will also increase the overall success rate of implants through an enhanced biocompatibility and reduce the time of osseointegration or bone integration. http://medicalxpress.com/news/2013-04-success-tooth-implants.html Dentistry Mon, 29 Apr 2013 09:28:22 EST news286446495 When it comes to healing the terrible wounds of war, success may hinge on the first blood clot – the one that begins forming on the battlefield right after an injury. http://medicalxpress.com/news/2013-02-artificial-platelets-soldiers-battlefield.html Medical research Fri, 15 Feb 2013 11:30:01 EST news280149428 Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation. http://medicalxpress.com/news/2013-01-central-nervous.html Medical research Tue, 29 Jan 2013 08:41:11 EST news278671263 Elderly or people with osteoporosis, smokers, diabetics or people who have had cancer are sometimes not eligible to receive dental implants as their bones are unable to correctly integrate the new prostheses which replace the root.

However, to function properly, the cells must often grow in a specific pattern or alignment. An innovative method for creating a stretched polymer scaffold that can support complex tissue architectures is described in an article in Tissue Engineering, Part C, Methods. http://medicalxpress.com/news/2013-01-d-biomimetic-scaffolds-regeneration-complex.html Medical research Thu, 10 Jan 2013 14:38:52 EST news277051106 Could ageing and damaged bones be replaced with implants based on wood?
