The effect on reducing cardiac workload via Langendorff perfusions on 13C-labeling and concentration of metabolites relevant to the HBP.
A, UDP-GlcNAc M+6 MPE. B, UDP-GlcNAc concentrations. C, UDP-GlcNAc M+6 concentrations. Horizontal bars, means ± S.E. (error bars); n = 4 for Beating 20 min, n = 3 for Nonbeating 20 min, n = 3 for Beating 30 min, n = 4 for Nonbeating 30 min, n = 4 for Beating 40 min, n = 4 for Nonbeating 40 min. *, p < 0.05 Beating versus Nonbeating at the same perfusion duration; ‡, p < 0.05 versus the immediately preceding perfusion duration for the same experimental group.
