Q beta and Q gamma components of intramembranous charge movement in frog cut twitch fibers
Intramembranous charge movement was measured in frog cut twitch fibers mounted in a double Vaseline-gap chamber with a TEA.Cl solution at 13-14 degrees C in the central pool. When a fiber was depolarized from a holding potential of -90 mV to a potential near -60 mV, the current from intramembranous charge movement was outward in direction and had an early, rapid component and a late, more slowl...
متن کاملEffects of conditioning depolarization and repetitive stimulation on Q beta and Q gamma charge components in frog cut twitch fibers
Charge movement was measured in frog cut twitch fibers with the double Vaseline-gap technique. Steady-state inactivation of charge movement was studied by changing the holding potential from -90 mV to a level ranging from -70 to -30 mV. Q beta and Q gamma at each holding potential were separated by fitting the Q-V plot with a sum of two Boltzmann distribution functions. At -70 mV Q beta and Q g...
متن کاملSeparation of Q beta and Q gamma charge components in frog cut twitch fibers with tetracaine. Critical comparison with other methods
Charge movement was measured in frog cut twitch fibers with the double Vaseline-gap technique. 25 microM tetracaine had very little effect on the maximum amounts of Q beta and Q gamma but slowed the kinetics of the I gamma humps in the ON segments of TEST-minus-CONTROL current traces, giving rise to biphasic transients in the difference traces. This concentration of tetracaine also shifted V ga...
متن کاملFactors affecting the appearance of the hump charge movement component in frog cut twitch fibers
Charge movement was measured in frog cut twitch fibers with the double Vaseline gap technique. Five manipulations listed below were applied to investigate their effects on the hump component (I gamma) in the ON segments of TEST minus CONTROL current traces. When external Cl-1 was replaced by MeSO3- to eliminate Cl current, I gamma peaked earlier due to a few millivolts shift of the voltage depe...
متن کاملSome inequalities for the q-beta and the q-gamma functions via some q-integral inequalities
Some new inequalities for the q-gamma, the q-beta and the q-analogue of the Psi functions are established via some q-integral inequalities. In classical analysis, integral inequalities have been well-developed and leading to a wide variety of applications in mathematics and physics (see [11–13] and references therein). In a survey paper [4], Dragomir et al. used certain clever integral inequali...
