Glutamate at the Vertebrate Neuromuscular Junction: From Modulation to Neurotransmission

Cells, 2019
Although acetylcholine is the major neurotransmitter operating at the skeletal neuromuscular junction of many invertebrates and of vertebrates, glutamate participates in modulating cholinergic transmission and plastic changes in the last.

Classification of Neuromuscular Junction and Tendon Recordings of Neuromuscular Diseases by Their Spectrogram

, 2021
In this study, the effect of spectrograms from neuromuscular junction and tendon records for normal, neurogenic and myopathic motor units being constructed via EMG Simulator v3.6 on the differential diagnosis were investigated.

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Diseases of the neuromuscular junction

Current Opinion in Pharmacology, 2002
The neuromuscular junction is a prototype synapse and it is also the site of well-characterised autoimmune and hereditary disorders. In the presynaptic terminal, voltage-gated potassium channels and voltage-gated calcium channels are subtly altered in genetic disorders and mutations in the enzyme that synthesises acetylcholine have been demonstrated in

Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

Advanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

High‐Density Magnetomyography With Optical Magnetometers Reveals Spatiotemporal Patterns of Evoked Muscle Activity

Advanced Materials Technologies, EarlyView.
Optically pumped magnetometers are employed to contactlessly map the spatiotemporal dynamics of the magnetic field linked to electrical activity of a skeletal muscle in vivo. It is demonstrated that localization of the clinically relevant innervation zone is feasible using this non‐invasive magnetic measurement modality. ABSTRACT Magnetomyography (MMG)

Clinical and functional studies of autoimmune disorders of neuromuscular transmission [PDF]

, 2015
Inherited and acquired disorders of the neuromuscular junction are an important cause of muscle weakness and fatigability. In this thesis I focus on the autoimmune disorders of neuromuscular transmission.

Temperature sensitivity of the pyloric neuromuscular system and its modulation by dopamine [PDF]

, 2013
We report here the effects of temperature on the p1 neuromuscular system of the stomatogastric system of the lobster (Panulirus interruptus). Muscle force generation, in response to both the spontaneously rhythmic in vitro pyloric network neural activity

Presynaptic spinophilin tunes neurexin signalling to control active zone architecture and function [PDF]

, 2015
Assembly and maturation of synapses at the Drosophila neuromuscular junction (NMJ) depend on trans-synaptic neurexin/neuroligin signalling, which is promoted by the scaffolding protein Syd-1 binding to neurexin.
