Muscle contraction: A mechanical perspective [PDF]

The European Physical Journal E, 2010
In this paper we present a purely mechanical analog of the conventional chemo-mechanical modeling of muscle contraction. We abandon the description of kinetics of the power stroke in terms of jump processes and instead resolve the continuous stochastic evolution on an appropriate energy landscape.

Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

FEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

Model-based control of skeletal muscle using muscle-contraction models

Journal of Biomechanical Science and Engineering
Bioactuators using skeletal muscle are expected to be applied to medical and welfare equipment as functional materials with self-growth functions. In this regard, their contraction force must be controlled with high accuracy for the desired operation ...

Electrical pulse stimulation reflecting the episodic nature of real‐life exercise modulates metabolic and secretory profile of primary human myotubes

FEBS Open Bio, EarlyView.
Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.

Experimental research models for skeletal muscle contraction

Journal of Physical Fitness and Sports Medicine, 2016
Skeletal muscle has an important role besides its obvious function in physical movement and locomotion; namely, it maintains whole-body metabolism. Maintaining muscle mass and quality with regular exercise is closely related to quality of life and a ...

The impact of Hnrnpl deficiency on transcriptional patterns of developing muscle cells

FEBS Open Bio, EarlyView.
We performed nanopore whole‐transcriptome sequencing comparing RNA from Hnrnpl‐knockdown versus control C2C12 myoblasts to investigate the contributions of Hnrnpl to muscle development. Our results indicate that Hnrnpl regulates the expression of genes involved with Notch signaling and skeletal muscle, particularly splicing patterns of specific muscle ...

Estimation of quadriceps femoris muscle dysfunction in the early period after surgery of the knee joint using shear-wave elastography

BMJ Open Sport & Exercise Medicine, 2018
Objectives Orthopaedic surgery of the knee joint results in functional deterioration of the quadriceps femoris muscle. However, little is known about quadriceps femoris muscle dysfunction in the early postsurgical period.

Translating a Preclinically Tested 15 Hz rTMS Protocol to Humans With Chronic Spinal Cord Injury: A Safety and Feasibility Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Repetitive transcranial magnetic stimulation (rTMS) is a non‐invasive brain stimulation strategy with a demonstrated potential to reinforce the residual pathways after a spinal cord injury (SCI). A preclinically tested high‐frequency (15 Hz) rTMS (15 Hz rTMS) protocol was shown to induce corticospinal tract axon regeneration growth ...

Bilateral versus Unilateral Training With Rhythmic Auditory Cueing in Stroke Rehabilitation: Effects on Upper Limb Function and Interhemispheric Inhibition

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Stroke is a leading cause of long‐term disability in adults, with upper limb hemiparesis being a common impairment. Traditional training is mostly aimed at paralyzed limbs, but the effect of bilateral training is still unclear.

Long‐Term Evaluation of Givinostat in Duchenne Muscular Dystrophy, and Natural History Comparisons

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives This ongoing, open‐label extension study is evaluating the long‐term safety, tolerability, and efficacy of givinostat, a Class I and II histone deacetylase inhibitor, in patients with Duchenne muscular dystrophy (DMD). Methods The recruited patients completed one of two prior clinical studies (one Phase 2 and one Phase 3 [EPIDYS ...
