Blood vessel inhibitor shows promise against metastatic thyroid cancer Thyroid cancer that has spread to distant sites has a poor prognosis, but an experimental drug that inhibits tumor blood vessel formation can slow disease progression in some patients, a research team led by investigators from The University of Texas M. D. Anderson Cancer Center reports in the July 3rd edition of The New England Journal of Medicine. Nanostructures improve bone response to titanium implants Titanium implants were successfully introduced by P.-I. Brånemark and co-workers in 1969 for the rehabilitation of edentulous jaws. After 40 years of research and development, titanium is currently the most frequently used biomaterial in oral implantology, and titanium-based materials are often used to replace lost tissue in several parts of the body.
