Polyetheretherketone (PEEK), which has biomechanical performance similar to that of human cancellous bone, is used widely as a spinal implant material. However, its bioinertness and hydrophobic surface properties result in poor osseointegration. This study applies a novel modification method, arc ion plating (AIP), that produces a highly osteoblast compatible titanium dioxide (TiO2) coatings on...

The two commonly performed surgical techniques used to repair displaced midshaft clavicle fractures are plate fixation or intramedullary nailing; however, despite recent evidence, the optimal method to treat such fractures remains a continued topic of debate. A meta-analysis of randomized controlled trials (RCTs) was conducted to evaluate long term function, complications, and operative duratio...

When distilled water from a tin-lined still served as the plating diluent, cells of Aerobacter aerogenes developed symptoms of metabolic injury as evidenced by increased counts on supplemented, as compared with minimal, plating medium. Cysteine was as effective as yeast extract as a supplement to the minimal medium in increasing the viable count. Mg(++) and, to a lesser extent, phosphate buffer...

INTRODUCTION: The stiffness of a fixation construct affects the mechanism and progression by which a fracture heals. Locked plating constructs have improved fixation strength in weak bone, but their relatively high stiffness may suppress interfragmentary motion (IFM) to a level insufficient for optimal promotion of secondary bone healing.[1] This is especially of concern when locked plates are ...

The immunomagnetic separation (IMS) is a technique that has been used to increase sensitivity and specificity and to decrease the time required for detection of Salmonella in foods through different methodologies. In this work we report on the development of a method for detection of Salmonella in chicken cuts using in house antibody-sensitized microspheres associated to conventional plating in...
