As mammals age, their neuromuscular junctions (NMJs) gradually change their form, acquiring an increasingly fragmented appearance consisting of numerous isolated regions of synaptic differentiation. It has been suggested that this remodelling is associated with impairment of neuromuscular transmission, and that this contributes to age-related muscle weakness in mammals, including humans. The un...
In patients with myasthenia gravis neuromuscular transmission has been tested in individual hypothenar and thenar motor units using trains of near threshold electrical stimuli delivered to the motor nerve. The most important observations included: (1) the proportion of motor units with pathological decrements varied from 0 to 90%, (2) the decrements in surface voltage were frequently much more ...
temporary paralysis is a rare manifestation of envenoming following the yellow iranian scorpion, odontobuthus doriae (o. doriae). thus, to elucidate the underlying mechanism, we investigated the neurotoxic effect of venom in the sciatic nerve, the possible mechanism in a mice model. the neurotoxicity and temperature effects in the venom-induced neurotoxicity were examined using the mouse sciati...
This review outlines the basic pharmacodynamic and pharmacokinetic properties of sugammadex for the cardiac anesthesiologist. It describes the different clinical scenarios when sugammadex can be used during cardiac surgery and gives clinical recommendations. Sugammadex is a unique reversal drug that binds a chemical complex with rocuronium and vecuronium, by which the neuromuscular blockade is ...
A blocker of postsynaptic acetylcholine receptors was isolated from venom of the Eastern green mamba Dendroaspis angusticeps, by gel filtration, ion-exchange and reverse phase high performance liquid chromatography. The isolated component blocks neuromuscular transmission and responses to exogenously applied acetylcholine in isolated chick biventer cervices preparations. These results suggest t...
Congenital myasthenic syndromes (CMS) are a rare heterogeneous group of inherited neuromuscular disorders associated with distinctive clinical, electrophysiological, ultrastructural and genetic abnormalities. These genetic defects either impair neuromuscular transmission directly or result in secondary impairments, which eventually compromise the safety margin of neuromuscular transmission. In ...
