Cardiomyocyte contractile properties in FVB and ALDH2 transgenic mice treated with or without streptozotocin. (A) Resting cell length; (B) peak shortening (PS), normalized to cell length; (C) maximal velocity of shortening (+ dL/dt); (D) maximal velocity of relengthening (- dL/dt); (E) time-to PS (TPS); (F) time-to-90% relengthening (TR90). Mean ± SEM, n = 101 to 102 cells from four mice per group. *P <0.05 versus FVB group; #
P <0.05 versus FVB-STZ group.
