FABP4 inhibits the cell shortening amplitude and the intracellular systolic peak Ca2+ in a dose-dependent manner in isolated rat cardiomyocytes, most likely due to a reduced excitation-contraction gain [ 22].
Indeed, direct nitrosylation of the ryanodine receptor RyR2 accounts for the enhanced excitation-contraction coupling gain and positive inotropic effect of cardiomyocyte stretch [ 42].
Main Outcome Measures: Tendon tapping force (designated as system input), reflex torque (as output), their dynamic relationship (characterized as system parameters tendon reflex gain, contraction rate, and reflex loop delay), Ashworth scale, and tendon reflex scale.
The results showed markedly increased system gain, contraction rate, and decreased reflex loop delay.
The system impulse response was obtained through system identification and characterized by the tendon reflex gain, contraction rate, reflex threshold in tapping force, and reflex loop delay.
The hypothesis was that hyperactive reflexes in SCI were associated with significantly increased reflex gain, contraction rate, and decreased reflex threshold and reflex loop delay.
To assess severity of the spastic state and characterize its properties following SCI, it is important to evaluate hyperactive reflexes quantitatively, including reflex gain, contraction rate, and threshold in SCI survivors.
Hyperactive reflexes in SCI were associated with significantly increased reflex gain, contraction rate, and decreased reflex threshold and reflex loop delay though there were different injury conditions within the spinal cord among those patients.
It was employed in relevant studies to make accurate measurements of both taps to the tendon and the reflex-mediated responses and to characterize their dynamic relationship in terms of tendon reflex gain, contraction rate, and tapping force threshold [ 12, 18, 25].
Static exercise can too be sub-categorized in relation to maximal voluntary contraction percentage (MVC) gained with increasing blood pressure [21].
They do this by measuring the effect on the excitation-contraction coupling (ECC) gain when they vary the diffusion constant of Ca2+, together with the parameters that determine the influx of Ca2+ ions to the cleft.
