Quantitative Spatiotemporal Analysis of Ultrasound Images of Fasciculations in ALS

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Fasciculations are a hallmark of amyotrophic lateral sclerosis (ALS), yet quantitative description of individual events on muscle ultrasound (MUS) is limited. We characterized the spatiotemporal kinematics of individual fasciculations to determine whether they differ between ALS and other neurogenic conditions.

In vitro and in vivo muscle mass and strength during the first week of critical illness

Intensive Care Medicine Experimental
Background Loss of muscle mass and strength is provoked by critical illness. Our primary aim was to study the development of muscle atrophy and weakness in vitro in isolated myofibers and in vivo muscle mass and in vitro muscle strength during the first ...

Gut microbiota-mediated betaine regulates skeletal muscle fiber type transition by affecting m6A RNA methylation and Myh7 expression

Gut Microbes
Skeletal muscle fiber composition is essential for maintaining muscle function and overall health. Growing evidence underscores the pivotal role of the gut-muscle axis in mediating the influence of gut microbiota on skeletal muscle development.

The Anterior Belly of the Digastric Muscle as a Novel Target for Needle Electromyography in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Needle electromyography (EMG) in the bulbar region aids in the diagnosis of amyotrophic lateral sclerosis (ALS) but remains technically challenging. The genioglossus muscle (GM) is commonly examined; however, pain and poor relaxation may limit its evaluation.

Taurine Transport in Chronically Stimulated Fast- and Slow-Twitch Muscles of the Rat

Japanese Journal of Pharmacology, 1986
Indirect stimulation via the sciatic nerve, 10 or 100 Hz stimulus trains of 1 sec duration, applied every 3 sec, 8 hr/day for 1-4 weeks increased taurine concentration of the extensor digitorum longus (EDL, fast-twitch) muscle of the rat. The uptake of [3H]-taurine into the EDL and tibialis anterior (TA, fast-twitch) muscle was also increased by the ...

Diagnostic Performance of the Strength‐Duration Test for Bedside Screening of Critical Illness Polyneuropathy and/or Myopathy: A Prospective, Cross‐Sectional Study

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Critical illness polyneuropathy and/or myopathy (CIP/CIM) is a major cause of weakness in the intensive care unit (ICU). The availability of conventional electrodiagnostic testing may be limited. Alternative electrophysiologic methods, including the strength‐duration test (SDT) and the stimulus electrodiagnosis test (SET ...

Contraction of glycerinated rabbit slow-twitch muscle fibers as a function of MgATP concentration [PDF]

, 1992
We have measured the isometric tension and force-velocity relationships of glycerinated rabbit slow-twitch semimembranosus muscle as a function of MgATP concentration ([MgATP]) and have compared the results with those obtained previously from fast-twitch

The Effect of Eight Weeks of High-Intensity Interval Training on Follistatin Gene Expression in the Fast and Slow Twitch Muscles of Rats with Myocardial Infarction [PDF]

Iranian Journal of Medical Sciences
Background: Myocardial infarction causes mitochondrial atrophy and loss of function by reducing mitochondrial volume. Therefore, researchers are interested in finding a way to reduce the injuries and treat them. The study aims to evaluate the effect of 8

Force‐velocity properties of fast‐twitch and slow‐twitch muscles of the kitten.

The Journal of Physiology, 1985
The characteristics of the isometric and force‐velocity properties of the fast‐twitch flexor digitorum longus (f.d.l.) and the slow‐twitch soleus muscles of the developing kitten were determined at post‐natal ages of 2 days and 1,2,4 and 6 weeks. The contractile properties of the isometric twitch and tetanus were similar to those previously reported by
