Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation

Advanced Robotics Research, EarlyView.
A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.

Absence of physiological Ca2+ transients is an initial trigger for mitochondrial dysfunction in skeletal muscle following denervation [PDF]

, 2017
Background: Motor neurons control muscle contraction by initiating action potentials in muscle. Denervation of muscle from motor neurons leads to muscle atrophy, which is linked to mitochondrial dysfunction.

Ethanol Exposure Causes Muscle Degeneration in Zebrafish

Journal of Developmental Biology, 2018
Alcoholic myopathies are characterized by neuromusculoskeletal symptoms such as compromised movement and weakness. Although these symptoms have been attributed to neurological damage, EtOH may also target skeletal muscle.

CONSTRUCTIVE TISSUE REMODELING BY EXTRACELLULAR MATRIX BIOSCAFFOLDS WITHIN THE AGING SKELETAL MUSCLE MICROENVIRONMENT [PDF]

, 2013
Adult mammalian skeletal muscle tissue retains inherent regenerative capability in response to injury. This regenerative response is contingent upon an activated progenitor cell population and a temporal transition from pro-inflammatory M1 to ...

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

Ontogenetic changes in skeletal muscle fiber type, fiber diameter and myoglobin concentration in the Northern elephant seal (Mirounga angustirostris)

Frontiers in Physiology, 2014
Northern elephant seals (Mirounga angustirostris) (NES) are known to be deep, long-duration divers and to sustain long-repeated patterns of breath-hold, or apnea.

Membrane Sealing in Frog Skeletal-Muscle Fibers [PDF]

Proceedings of the National Academy of Sciences, 1973
Self-sealing, not found in frog skeletal muscle fibers immersed in Ringer's solution, can be induced by solutions rich in calcium ion. Strontium replaced calcium on the sealing process, but magnesium did not. The sealing accomplished in high-calcium media was preserved in those fibers reimmersed in normal Ringer's solution.

Complex coordination of cell plasticity by a PGC-1α-controlled transcriptional network in skeletal muscle [PDF]

, 2015
Skeletal muscle cells exhibit an enormous plastic capacity in order to adapt to external stimuli. Even though our overall understanding of the molecular mechanisms that underlie phenotypic changes in skeletal muscle cells remains poor, several factors ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...
