Article Snippet: The effect of phosphate on the relaxation of isometrically contracting single skinned fibres from the semitendinosus muscle of the frog Rana temporaria has been investigated using laser pulse photolysis of the photolabile caged calcium-chelator diazo-2 to rapidly reduce the Ca2+ (<2 ms) within the fibre and produce >90% relaxation of force.. Relaxation occurred in two phases – an initial linear shoulder which lasted approximately 20 ms followed by a double-exponential phase which gave two rate constants, k1 (43.4±1.8 s–1, mean ±SEM, n=14) and k2 (15.6±0.3 s–1, mean ±SEM, n=14) at 12°C.. Increased phosphate concentrations did not affect the linear phase, but slowed the double-exponential phase following photolysis of diazo-2 in a dose-dependent fashion (k50= 0.9 mM for k1, 1.15 mM for k2).

Article Snippet: The aim of this study was to compare the effects of increased concentrations of MgADP, inorganic phosphate (Pi) and H+ ([MgADP], [Pi] and [H+], respectively) on the rate of relaxation in two different muscle types: skinned muscle fibres from the frog Rana temporaria and myofibrillar bundles from the giant Pacific acorn barnacle Balanus nubilus.. Relaxation transients are produced by the photolysis of diazo-2 and are well fitted with a double exponential curve, giving two rate constants: k1 [5.6±0.1 s–1 for barnacle, n=30; 26.3±0.7 s–1 for frog, n=14 (mean±SEM)] and k2 [0.6±0.1 s–1 in barnacle, n=30; 10.4±1.0 s–1 in frog, n=14 (mean±SEM)], at 10°C.. Decreasing the pH by 0.5 pH units did not significantly affect k1 for barnacle relaxation [5.6±0.1 s–1 (mean±SEM), n=15] compared to the decrease in k1 of 40% seen in frog. Article Title: The effects of the inotropic agent EMD 57033 on activation and relaxation kinetics in frog skinned skeletal muscle. Article Snippet: The effect of the cardiotonic sensitizing drug EMD 57033 was studied in frog skinned skeletal muscle fibres at 12°C to provide a baseline for skeletal muscle studies and for comparison with cardiac fibres.. The activation and relaxation of fibres were induced by laser flash photolysis of the caged calcium NP-EGTA, and caged calcium chelator diazo-2 respectively.. EMD 57033 (10 μM) slightly increased the rate of relaxation (rate constant k1 changing from 24.0±2.9 s–1 in control to 28.1±3.2 s–1) but had no significant effect on the rate of activation (k1=9.6±0.9 s–1 in control conditions, 9.7±1.6 s–1 with EMD 57033).
