Does protein kinase A modulate A-type potassium currents of larval zebrafish ( Danio rerio ) white muscle fibres?
PKA modulates the A-type K(+) current in zebrafish skeletal muscle and affects action potential properties. Our results provide new insights into the role of A-type K(+) channels in muscle physiology.
Prediction of fluid responsiveness failed 1 hr after successful cardiopulmonary resuscitation from cardiac arrest. Four hours after return of spontaneous circulation, however, the variables pulse pressure variation, variation of the velocity time integral, and global end-diastolic volume index, but not stroke volume variation, enabled prediction of fluid responsiveness and may, therefore, be considered for subsequent hemodynamic optimization after successful cardiopulmonary resuscitation.
