Layered approach may yield stronger, more successful bone implants

Researchers from the American Dental Association Foundation and NIST have developed a new method for layering two kinds of biomaterials into one strong, yet porous unit that may lead to improved reconstruction or repair of bones.

1. Bone-growing nanomaterial could improve orthopaedic implants
   09-17-2007 · EurekAlert!
   Bone-forming cells grow faster and produce more calcium on anodized titanium covered in carbon nanotubes compared with plain anodized titanium and the non-anodized version currently used in orthopaedic implants, new Brown University research shows. The work, published in Nanotechnology, uncovers a new material that can be used to make more successful implants. The research also shows tantalizing promise for an all-new device: a "smart" implant that can sense and report on bone growth.

   10-17-2006 · EurekAlert!
   It is so small, you can barely see it, but a microsensor created by University of Alberta engineers may soon make a huge difference in the lives of people recovering from hip replacement surgery. The U of A research team has invented a self-powered wireless microsensor for monitoring the bone healing process after surgery -- it is so tiny it can fit onto the tip of a pen.

5. MGH researchers confirm that bone marrow restores fertility in female mice
   07-31-2007 · EurekAlert!
   A new study from Massachusetts General Hospital researchers confirms that female mice that receive bone marrow transplantation after fertility-destroying chemotherapy can go on to have successful pregnancies throughout their normal reproductive life. The report verifies that donor marrow can restore fertility in mice through an as-yet unidentified mechanism. While donor-derived oocytes were observed in the ovaries of marrow recipients, all pups born were from the recipients' own eggs.

6. Smaller is stronger -- now scientists know why
   01-02-2008 · EurekAlert!
   As metal structures get smaller -- as their dimensions approach the micrometer scale or less -- they get stronger. Now scientists from Lawrence Berkeley National Laboratory, Hysitron Inc. and General Motors Research and Development Center, working at the National Center for Electron Microscopy, have learned how. The researchers observed that compressing nanoscale pillars of nickel drives out dislocations and can produce a perfect crystal -- a process the researchers call "mechanical annealing."

7. New treatment for glaucoma shows promise in laboratory, say Iowa State researchers
   08-01-2007 · EurekAlert!
   Iowa State University researchers developed a new technique that successfully treated rats for blindness caused by glaucoma. They previously determined that animals with glaucoma increase production of neurotrophins in an attempt to shield against blindness. They imitated that process in the laboratory, modifying bone marrow-derived stem cells and transplanting them into the eyes. Their experimental treatment will be used on dogs in the next year. If successful, it is expected to move to human trials.
