Muscle spindles of the rat sternomastoid muscle

European 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]

Archives 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,

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

European 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

Skeletal 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.

Aging of Skeletal Muscle Fibers [PDF]

Annals of Rehabilitation Medicine, 2015
Aging has become an important topic for scientific research because life expectancy and the number of men and women in older age groups have increased dramatically in the last century. This is true in most countries of the world including the Republic of Korea and the United States. From a rehabilitation perspective, the most important associated issue

Bile Acids Induce Alterations in Mitochondrial Function in Skeletal Muscle Fibers

Antioxidants, 2022
Cholestatic chronic liver disease is characterized by developing sarcopenia and elevated serum levels of bile acids. Sarcopenia is a skeletal muscle disorder with the hallmarks of muscle weakness, muscle mass loss, and muscle strength decline.

Muscle Fiber Conduction Velocity, Muscle Fiber Composition, and Power Performance

Medicine & Science in Sports & Exercise, 2016
The aim of this study was to explore the relationship between muscle fiber conduction velocity (MFCV), fiber type composition, and power performance in participants with different training background.Thirty-eight young males with different training background participated: sedentary (n = 10), endurance runners (n = 9), power trained (n = 10), and ...

Supraspinatus and deltoid muscle fiber composition in rotator cuff tear conditions

JSES International, 2020
Background: Rotator cuff (RC) tears are associated with RC muscle atrophy and changes in composition that are crucial to the prognosis of RC repair. The aim of this study was to characterize muscle fiber composition in the supraspinatus (SS) muscle under

Damaged muscle fibers might masquerade as hybrid fibers – a cautionary note on immunophenotyping mouse muscle with mouse monoclonal antibodies

European Journal of Histochemistry, 2018
We report that, labeling mouse muscle tissue, with mouse monoclonal antibodies specific to slow or fast myosin heavy chain (sMyHC and fMyHC, respectively), can lead to artefactual labeling of damaged muscle fibers, as hybrid fibers (sMyHC+ and fMyHC ...

Mechanisms of exercise-induced preconditioning in skeletal muscles

Redox Biology, 2020
Endurance exercise training promotes numerous biochemical adaptations within skeletal muscle fibers culminating into a phenotype that is safeguarded against numerous perils including doxorubicin-induced myopathy and inactivity-induced muscle atrophy ...
