The latent dedifferentiation capacity of newt limb muscles is unleashed by a combination of metamorphosis and body growth

open access: yesScientific Reports, 2022
Newts can regenerate their limbs throughout their life-span. Focusing on muscle, certain species of newts such as Cynops pyrrhogaster dedifferentiate muscle fibers in the limb stump and mobilize them for muscle creation in the regenerating limb, as they ...

Progressive impairment of CaV1.1 function in the skeletal muscle of mice expressing a mutant type 1 Cu/Zn superoxide dismutase (G93A) linked to amyotrophic lateral sclerosis [PDF]

open access: yes, 2016
Background: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disorder that is typically fatal within 3–5 years of diagnosis. While motoneuron death is the defining characteristic of ALS, the events that underlie its pathology are

Role of physiological ClC-1 Cl- ion channel regulation for the excitability and function of working skeletal muscle. [PDF]

open access: yes, 2016
Electrical membrane properties of skeletal muscle fibers have been thoroughly studied over the last five to six decades. This has shown that muscle fibers from a wide range of species, including fish, amphibians, reptiles, birds, and mammals, are all ...

Severely atrophic human muscle fibers with nuclear misplacement survive many years of permanent denervation

open access: yesEuropean Journal of Translational Myology, 2016
Likewise in rodents, after complete spinal cord injury (SCI) the lower motor neuron (LMN) denervated human muscle fibers lose completely the myofibrillar apparatus and the coil distribution of myonuclei that are relocated in groups (nuclear clumps) in ...

Muscle spindles of the rat sternomastoid muscle

open access: yesEuropean Journal of Translational Myology, 2018
The sternomastoid (SM) muscle in rodents presents a peculiar distribution of fiber types with a steep gradient from the ventral, superficial, white portion to the dorsal, deep, red region, where muscle spindles are restricted. Cross section of the medial

The effect of breed and body weight at slaughter on histochemical muscle fiber characteristics and meat quality of longissimus lumborum and semitendinosus lamb muscles [PDF]

open access: yesArchives Animal Breeding, 2023
The skeletal muscles of mammals are composed of fibers of different morphological, metabolic and functional characteristics. The properties of muscle fibers may be determined genetically as well as by environmental factors such as the age of the animals,

Flux control of cytochrome c oxidase in human skeletal muscle [PDF]

open access: yes, 2000
In the present work, by titrating cytochrome c oxidase (COX) with the specific inhibitor KCN, the flux control coefficient and the metabolic reserve capacity of COX have been determined in human saponin-permeabilized muscle fibers. In the presence of the

Histochemical demonstration of three types of muscle fibers of the intercostal muscles. A study on oxidative enzymes [PDF]

open access: yes, 1963
Since the classic work of Ranvier, it is well known that the mammalian striated muscle is composed of two types of muscle fibers, i. e., the red and white muscle fibers.

Persistent muscle fiber regeneration in long term denervation. Past, present, future

open access: yesEuropean Journal of Translational Myology, 2015
Despite the ravages of long term denervation there is structural and ultrastructural evidence for survival of muscle fibers in mammals, with some fibers surviving at least ten months in rodents and 3-6 years in humans.

High-throughput proteomics fiber typing (ProFiT) for comprehensive characterization of single skeletal muscle fibers

open access: yesSkeletal Muscle, 2020
Background Skeletal muscles are composed of a heterogeneous collection of fiber types with different physiological adaption in response to a stimulus and disease-related conditions.
