Characterization of ionotropic glutamate receptors in insect neuro-muscular junction

Comparative Biochemistry and Physiology Part - C: Toxicology and Pharmacology, 2009
Pharmacological properties of ionotropic glutamate receptors from Calliphora vicina larvae neuro-muscular junction (C. vicina iGlurs) were studied by two-electrode voltage-clamp technique. Characteristics of the ion channel pore were analyzed using a 26-member series of channel blockers, which includes mono- and dicationic derivatives of adamantane and

Modulation of Neurotransmitter Release by Carbon Monoxide at the Frog Neuro-Muscular Junction [PDF]

open access: yesCurrent Drug Metabolism, 2007
Carbon monoxide (CO) is an endogenous gaseous messenger, which regulates numerous physiological functions in a wide variety of tissues. Using extracellular microelectrode recording from frog neuro-muscular preparation the mechanisms of exogenous and endogenous CO action on evoked quantal acetyl-choline (Ach) release were studied.

GRADUAL NERVE ELONGATION AFFECTS NERVE CELL BODIES AND NEURO-MUSCULAR JUNCTIONS

Hand Surgery, 2005
The purpose of this study is to clarify the reactions of the neuro-muscular junction and nerve cell body to gradual nerve elongation. The sciatic nerves of Japanese white rabbits were lengthened by 30 mm in increments of 0.8 mm/day, 2.0 mm/day and 4.0 mm/day.

Action of Pyrrolizidine Alkaloids on the Neuro-Muscular Junction

Nature, 1959
MEDIAN lethal doses of the plant pyrrolizidine alkaloids, heliotrine and lasiocarpine, have been determined by Bull et al.1. Deaths occurred from hepatotoxic effects except in some female rats given heliotrine.

Glutamate as a transmitter: Comparison between the crustacean neuro-muscular junction and the chicken retina

Comparative Biochemistry and Physiology A, Comparative Physiology, 1973
Abstract 1. 1. The continued presence of the transmitter at a synapse can be expected to block synaptic conduction. This criterion was applied to the postulated transmitter role of glutamate at the crustacean neuro-muscular junction and synapses in the chicken retina. 2. 2.

Presynaptic effects of carbon monoxide in frog neuro-muscular junction [PDF]

open access: yes, 2005
The effects of CO and zinc(II)protoporphyrin (ZnPP-9) hemoxigenase blocker on acetylcholine release in frog neuro-muscular junction are investigated and the role of guanylatecyclase in CO effects is revealed. It is found that CO, similar to NO acts as endogenic modulator in frog (and generally cold-blooded) neuro-muscular junction and the soluble ...
