Action potential-driven current transients were recorded from sensory cilia and used to monitor the spike frequency generated by olfactory receptor neurons, which were maintained in their natural position in the sensory epithelium. Both basal and messenger-induced activities, as elicited with forskolin or cyclic nucleotides, were dependent on the presence of mucosal Na+. The spike rate decrease...

It is generally assumed that in cardiac Purkinje fibers the hyperpolarization activated inward current i(f) underlies the pacemaker potential. Because some findings are at odds with this interpretation, we used the whole cell patch clamp method to study the currents in the voltage range of diastolic depolarization in single canine Purkinje myocytes, a preparation where many confounding limitati...

Enkephalins and enkephalin-containing polypeptides were released from perfused bovine adrenal glands by nicotine and Ba2+, agents that release catecholamines. All the enkephalin-containing polypeptides that are normally found in the adrenal medulla were released by the two secretagogues in approximately the same proportions as are present in adrenal chromaffin granules.

Ba2+ and Ca2+ prevent and reverse the Btk delta-endotoxin inhibition of the short-circuit current in isolated lepidopteran midgut. These findings support the K+ pump-leak steady-state model for midgut K+ homeostasis and the K+ channel mechanism of Bt toxin action. They provide a new tool with which to study the interactions between Bt toxin and midgut cell membranes.

The ligand L1 forms a dinuclear double helicate with Cu+ but upon addition of Ba2+ to the system a side-by-side species is formed both in solution and in the solid state; in the presence of Na+ both the helicate and the side-by-side species are formed in roughly equal amounts in solution.
