We studied the distribution of HLA-D--related (DRw) antigens in 40 patients with juvenile diabetes mellitus (JDM) and 79 matched controls. We found that DRw2 was significantly decreased in the JDM group, suggesting a protective effect of the antigen and that the decrease observed in B7 was secondary. HLA-DRw3 and HLA-DRw4 were increased in the diabetic(More)
Ultrasmooth nanostructured diamond (USND) films were synthesized on Ti-6Al-4V medical grade substrates by adding helium in H(2)/CH(4)/N(2) plasma and changing the N(2)/CH(4) gas flow from 0 to 0.6. We were able to deposit diamond films as smooth as 6 nm (root-mean-square), as measured by an atomic force microscopy (AFM) scan area of 2 μm(2). Grain size was(More)
