Diagnostic Testing in Suspected Primary Mitochondrial Myopathy

open access: yesMuscles, 2023
The diagnosis of primary mitochondrial myopathy is often delayed by years due to non-specific clinical symptoms as well as variable testing of mitochondrial disorders.

Effects of ATP on Time Parameters of Contractility of Rats’ Slow and Fast Skeletal Muscles in Normal and Hypothermic Conditions

open access: yesMuscles, 2023
We have previously shown that hypothermia leads to an increase in the synaptic modulating effects of ATP but not of adenosine in several different animal skeletal muscles.

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

open access: yes, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

Information decomposition of multichannel EMG to map functional interactions in the distributed motor system [PDF]

open access: yes, 2019
The central nervous system needs to coordinate multiple muscles during postural control. Functional coordination is established through the neural circuitry that interconnects different muscles.

In Vivo Time- Resolved Microtomography Reveals the Mechanics of the Blowfly Flight Motor [PDF]

open access: yes, 2014
Dipteran flies are amongst the smallest and most agile of flying animals. Their wings are driven indirectly by large power muscles, which cause cyclical deformations of the thorax that are amplified through the intricate wing hinge.

Functional characterization of orbicularis oculi and extraocular muscles [PDF]

open access: yes, 2016
The orbicularis oculi are the sphincter muscles of the eyelids and are involved in modulating facial expression. They differ from both limb and extraocular muscles (EOMs) in their histology and biochemistry. Weakness of the orbicularis oculi muscles is a

Fluid-driven origami-inspired artificial muscles

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Artificial muscles are flexible actuators with capabilities similar to, or even beyond, natural muscles. They have been widely used in many applications as alternatives to more traditional rigid electromagnetic motors. Numerous studies focus

Degradative Signaling in ATG7-Deficient Skeletal Muscle Following Cardiotoxin Injury

open access: yesMuscles, 2023
Skeletal muscle is a complex tissue comprising multinucleated and post-mitotic cells (i.e., myofibers). Given this, skeletal muscle must maintain a fine balance between growth and degradative signals.

Realizing the potential of dielectric elastomer artificial muscles

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance To build new robots that can safely interact with people, while completing complex tasks, we need artificial muscles. Ideally, these devices would be completely soft, as strong as natural muscles, and powered by electricity for easy ...

Physical Function Tests Are Potential Tools to Identify Low Physical Resilience in Women after Breast Cancer Treatment

open access: yesMuscles, 2023
Background: This study sought to investigate whether different physical function tests (objective measures of physical performance) may identify a low physical resilience in breast cancer survivors (BCS).
