SIRT1 enzyme activity after T-H and resveratrol (RSV) treatment. Activity of SIRT1 enzyme was measured in total protein extracts from left ventricular tissues of rats subjected to sham or T-H procedure. RSV or sirtinol (Stnl) and RSV were administered in a subset of the T-H group. Results were normalized to sham levels, and the significance was calculated by the unpaired t test with the Welch correction. n = 4–7; bars = mean ± standard error of the mean (SEM). *p < 0.05 compared with sham.
