Effects of catecholamines on K-related membrane currents in the bullfrog atrial muscle were studied under voltage clamp using the double sucrose-gap technique. Isoproterenol (10(-8)-10(-6) M) and norepinephrine (5 X 10(-6)-10(-5) M) induced an outward shift of the basal current level and enhanced both the background current (Ib) for hyperpolarization and the instantaneous outward current for de...

Information systems integration (ISI) represents the degree of cooperation in information system practices between business functions within a firm and between a firm and its trading partners. Although the establishment of information systems integration objective has been reported as one of the key concerns of top management because ISI enhances the firms’ competitiveness and growth, the class...

OBJECTIVE The purpose of the present study was to validate various surrogate estimates of insulin sensitivity (IS) in a renal transplant population and to assess the influence of immunosuppressive and antihypertensive therapy on insulin resistance (IR) after renal transplantation. RESEARCH DESIGN AND METHODS A total of 167 consecutive renal transplant recipients without previously known diabe...

Data from neurons in vivo have shown that spike output can often sustain episodes of high variability. Theoretical studies have indicated that the high conductance state of neurons brought on by synaptic activity can contribute to an increase in the variability of spike output by decreasing the integration timescale of the neuron. In the present work, we were interested in understanding how bac...
