Sea Coral Can Make For Better Bone Grafts
2013-12-01 05:43:32

Ranjini Raghunath for redOrbit.com - Your Universe Online Changes to artificial bone grafts made from sea coral material make them more easy-to-dissolve while retaining their bone-healing properties, according to new research from Swansea University in the UK. Artificial bone grafts made from calcium compounds are an attractive alternative to traditional “autografts.” Autografts are pieces of bone taken from other parts of the body and implanted in the areas where the bone is...

Researchers Use Bioactive Film To Coat Spinal Polymer Implants To Improve Bonding With Bone
2013-02-19 11:02:32

North Carolina State University Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants — which are often used in spinal surgeries. The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical...

Coating a bone graft with an inorganic compound found in bones and teeth may significantly increase the likelihood of a successful implant, according to Penn State researchers. Natural bone grafts need to be sterilized and processed with chemicals and radiation before implantation into the body to ensure that disease is not transmitted by the graft. Human bones have a rough surface. However, once a graft is sterilized the surface changes and is not optimal for stimulating bone formation in...

An artificial bone scaffold produced by researchers in South Korea could enhance the treatment of bone damage and defects through bone graftsTokyo, July 23, 2012 - (JCN Newswire) - Traditionally, bone grafts require material to be transplanted from either another bone of the patient or from a donor. Artificial grafts offer an easier and less risky process, providing an artificial scaffold on which bone cells can grow. However, developing a material with ideal characteristics has proved...

British scientists say they've discovered bacteria that produce hydroxyapatite, a mineral form of calcium, could be used to make better bone implants. Researchers at the University of Birmingham, led by Professor Lynne Macaskie, said they discovered serratia bacteria cells stick tightly to surfaces such as titanium alloy, polypropylene, porous glass and polyurethane foam. The cells form a biofilm layer containing biopolymers that acts as a strong adhesive. The scientists said a hydroxyapatite...

 Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings' longevity."Dentin adhesives bond well initially, but then the hybrid layer between the adhesive and the dentin begins to break down in as little as one year," says Dr. Franklin Tay, associate professor of endodontics in the MCG School of...

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing. The report appears in the June 14 issue of the American Chemical Society's journal Chemistry of Materials. ACS is the world's largest scientific society. The success of a bone graft depends on the ability of the scaffold...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
