Figure 2From: Altered myocardial substrate metabolism is associated with myocardial dysfunction in early diabetic cardiomyopathy in rats: studies using positron emission tomographyIn vitro function of single cardiomyocytes. Single cardiomyocyte mounted between a force transducer and piezoelectric motor (A). Maximal (Fmax) and passive (Fpassive) force (B), maximal rate of force redevelopment (K tr max) (C) and calcium sensitivity (D) in ZL rats (open bars) and ZDF rats (filled bars). Data are expressed as mean ± SEM, n = 4, * p < 0.005.Back to article page
