BACKGROUND AND PURPOSE Total elbow replacement (TER) is used in the treatment of inflammatory arthropathy, osteoarthritis, and posttraumatic arthrosis, or as the primary management for distal humeral fractures. We determined the annual incidence of TER over an 18-year period. We also examined the effect of surgeon volume on implant survivorship and the rate(More)
The determination of protein structure by NMR is restricted at molecular masses above 10 kDa by overlapping resonances. One way of overcoming this problem is to label the protein with 15N. The conventional way to record 15N spectra is to use heteronuclear multiple-quantum coherence. We present here an alternative approach based on 15N single-quantum(More)
Nuclear magnetic resonance (NMR) studies of the c subunit of F1F0 ATP synthase from Escherichia coli are presented. A combination of homonuclear (1H-1H) and heteronuclear (1H-15N) 2D and 3D methods was applied to the 79-residue protein, dissolved in trifluoroethanol. Resonance assignment for all the backbone amide groups and many C alpha H side-chain(More)
