At 20 (0)C, both quantal and non-quantal spontaneous acetylcholine release (expressed as miniature endplate potential frequency [f-MEPPs] and the H-effect, respectively) increased during the first 30 min of hypoxia in solution with normal extracellul

The effects of an acetylcholine analogue, carbachol (CCh), and a purified irreversible nicotinic antagonist, α-bungarotoxin (BTX), on the frequency of the miniature endplate potentials (mEPPs) at the neuromuscular junction of the frog were tested at

The purpose of this report is to describe what progress was made in defining and explaining the phenomenon of NQR and to stress some functional roles of this type of release, as based on our own data and other observations.

A model of concentration changes across the synaptic cleft during a single quantum release is presented that can be used for description and characterization of the kinetic in postsynaptic current development under the influence of different antagoni

Ligand-gated ionic channels are integral membrane proteins that enable rapid and selective ion fluxes across biological membranes. In excitable cells, their role is crucial for generation and propagation of electrical signals. This survey describes r

The resting membrane potential (V(m)) of isolated somatic longitudinal muscles of the earthworm Lumbricus terrestris was studied by glass microelectrodes. The inhibition of chloride permeability by low pH did not affect V(m) of the muscle fibers in i

Uni-quantal endplate currents (EPCs) were recorded extracellularly at the frog neuromuscular synapse and their latency dispersions expressed as P(90) were estimated in the presence of acetylcholine. Stimulation-evoked EPCs with long release latencies

The conduction velocity of the nerve terminal, mean quantal content, and release latencies of uniquantal endplate currents (EPCs) were recorded in proximal, central, and distal parts of the terminal by extracellular pipettes located 5, 50, and 100 mi

Adult and embryonic nicotinic receptors expressed in COS cells have similar affinities for acetylcholine but differ in their Hill coefficient. Parameters of wild-type receptors were compared with those of receptors with mutated delta and gamma subuni

Resting non-quantal acetylcholine (ACh) and probably glutamate (Glu) release from nerve endings activates M1- and NMDA-receptor mediated Ca2+ entry into the sarcoplasm with following activation of NOS and production of NO. This is a trophic message f
