Autoimmune Channelopathies at Neuromuscular Junction

Frontiers in Neurology, 2019
The neuromuscular junction, also called myoneural junction, is a site of chemical communication between a nerve fiber and a muscle cell. There are many types of channels at neuromuscular junction that play indispensable roles in neuromuscular signal ...

The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]

, 2020
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

Stepwise Regulation of Cellular Oxidative Stress via Conductive‐Piezoelectric Integrated Microstructured Conduits for Enhanced Nerve Regeneration

Advanced Science, EarlyView.
This study presents a conductive‐piezoelectric integrated microstructured conduit for peripheral nerve regeneration. The conduit combines reduced graphene oxide with a piezoelectric nanofiber membrane, enhancing nerve repair through physical guidance, oxidative stress inhibition, and ultrasound‐activated electrical stimulation.

Mechanisms for the Age-related Increase in Fatigability of the Knee Extensors in Old and Very Old Adults [PDF]

, 2018
The mechanisms for the age-related increase in fatigability during high-velocity contractions in old and very old adults ({greater than or equal to}80 yrs) are unresolved. Moreover, whether the increased fatigability with advancing age and the underlying

A Wearable System Featuring Biomimetic Spatially Distributed Iontronic Sensing Array for Dynamic Monitoring of Deep Tissue Modulus

Advanced Science, EarlyView.
A fully wearable system enables real‐time, dynamic, and accurate monitoring of Young's modulus in multilayer tissues containing deep muscle. It demonstrates high accuracy and robustness across simulations, benchtop validations, and human testing. It quantifies edema severity and tracks muscle stiffness during rest, loaded elbow flexion, rope skipping ...

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

Advanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...
