Normal form results for default logic,h subdivisions are often thermodynamically misleading. There is an activation term that relates to Ca . release and retrieval, a work term and a stress or load-dependent heat term. The work and load-dependent energy terms presumably have their origin in the actin-activated myosin ATPase. It can be s

The mitochondrial activity was measured by (1) continuous determination of the O. uptake rate, (2) the rate of .CO. production from labelled glucose or FFA and (3) separate measu

Vector Delay Differential Equations,n electrode..Using a diffusion model we eliminated the effect of oxygen storage on the measured time course of oxygen uptake to determine the time constant of mitochondrial “off” kinetics. Two different approaches were followed. In Method 1, two steady-state levels were compared, whereas in Method 2

By combining these techniques, we tested the hypothesis that the velocity of the creatin

In this study a comparison was made between the rate of ATP hydrolysis estimated from the stable maintenance heat rate and the mechanical performance of fibres of type 1, 2 and 3..In the experiments, firstly the force-velo

Orthonormal Series and Approximation,rations were realized on representative samples of normotensive rats and spontaneously hypertensive rats (SHR) in compensated stages, as well as in SHR in a state of congestive cardiac failure. Cardiac dynamic measurements were performed under Urethane anaesthesia and open chest conditions. Myosin i
