Pressbox (Press Release) - The position of each MLC band was determined using standards containing multiple single muscle fibres (i.e. expressing MHC I, IIA, IIX fibres) and myosin extracted from human skeletal muscle and cardiac tissue, as described previously (Okada et al. 2008). Gels were scanned and each MLC isoform band was quantified by densitometry (Quantity One, BioRad) and expressed as a molar fractional abundance by dividing the band intensity signal by its respective PIK-3 molecular weight (23 for MLC 1f, 17 for MLC 2f and 15 for MLC 3f) and expressing this value relative to the total MLC signal. All data are reported as mean ��s.e.m. Two-sample Student's t tests were used to examine differences between control and heart failure groups for most variables, except for the elastic and viscous moduli since these were measured across different sinusoidal oscillation frequencies. For the moduli data, a repeated measures analysis was used, with frequency as a repeated measure, and pair-wise comparisons performed between the control and heart failure groups at each frequency. Relationships between variables were determined using Pearson correlation coefficients. All analyses were conducted with SPSS software version 16 (SPSS Inc.; Chicago, IL, USA). Physical characteristics for heart failure patients and controls are shown in Table 1. Groups were similar for age, height, body mass and body mass index, although was lower (P <0.01) in patients compared to controls. Daily physical activity level measured by accelerometry over an average of 7.5 �� 0.7 days did not differ between patients and Ion Channel Ligand Library solubility dmso controls. At the standard amplitude of 0.125% fibre length for the Lenvatinib purchase sinusoidal length perturbations applied to muscle preparations in studies carried out in our laboratory and others for insect flight (Miller et al. 2009a), cardiac (Mulieri et al. 2002; Palmer et al. 2004) and skeletal muscle (Wang & Kawai, 1997), we found a significant amount of non-linearity in the force response in MHC I human skeletal muscle fibres over a broad range of frequencies. To assure a linear force response, a requirement of our method of analysis, we reduced the amplitude of the applied sinusoidal length perturbations. We found that length changes of 0.05% fibre length resulted in a linear force response, while maintaining an adequate signal-to-noise ratio. Interestingly, this change in the amplitude of the sinusoidal length oscillations uncovered a unique characteristic of MHC I human skeletal muscle fibres. Figure 3A shows the characteristic Nyquist plot for MHC I fibres using 0.125% length amplitude, which is similar in form to that observed in MHC I fibres from rabbits (Wang & Kawai, 1997). Use of 0.05% length amplitude in MHC I fibres, however, revealed a ��notch�� that typically occurred within the frequency range of 1 to 4 Hz (notch labelled at 2.75 Hz in Fig. 3A).
