Time-resolved single-molecule observations by high-speed atomic force microscopy (HS-AFM), have greatly advanced our understanding of how proteins operate to fulfill their unique functions. Using this device, we succeeded in visualizing two members of the protein disulfide isomerase family (PDIs) that act to catalyze oxidative folding and…[Read more]

For titanium screws, BV/TV remained stable throughout the study. For nacre screws, the BV/TV decrease was not statistically different. A significant difference was found between nacre and titanium screws at 6 months but not at 12 months. The screw heads, outside the bone shaft, were not eroded even after 12 months. Erosion of nacre occurred during…[Read more]
