NY Oral Surgeon gets 18-54 yrs in Jail for Bodysnatching

Michael Mastromarino, the leader of the body-snatching ring that plundered the corpse of broadcaster Alistair Cooke apologized to the victims as he was sentenced to 18-54 years in prison. “I am deeply sorry for all the emotional pain I have caused to donor families and donor recipients,” he told the Brooklyn Supreme Court in New York. Mastromarino once ran a dental practice on New York`s Fifth Avenue specializing in dental implant surgery. But he was forced to surrender his dental

Nanocrystalline Titanium shows Exceptional Mechanical Properties

Novel processing of commercially pure titanium (CP Ti) has produced exceptional mechanical properties and recent clinical trials have proven its superior biocompatibility as well. CP Ti is desirable mainly for its superior biocompatibility, but suffers from low strength compared to either steel or alloyed titaniums. Severe plastic deformation (SPD) processing aims to get microstructural refinement to a level not achievable with traditional processing yielding nanocrystalline titanium. Fatigue life has nearly doubled and although damage tolerance suffered, the levels are still

Nanoparticles Aid Bone Growth

Bioengineers and bioscientists at Rice University and Radboud University in Nijmegen, Netherlands, have shown they can grow denser bone tissue by sprinkling stick-like nanoparticles throughout the porous material used to pattern the bone. To grow new bone, tissue engineers typically place bone cells on porous, biodegradable materials called scaffolds, which act as patterns. With the right chemical and physical cues, the cells can be coaxed into producing new bone. As the scaffold degrades, it is replaced by new bone. “Ideally,
