Fiber types and fiber diameters in canine respiratory muscles

Journal of Applied Physiology, 1987
In the present study, we measured fiber types and fiber diameters in canine respiratory muscles and examined regional variation within the diaphragm. Samples of eight diaphragm regions, internal intercostals, external intercostals, transversus abdominis, and triceps brachii were removed from eight adult mongrel dogs, frozen, and histochemically ...

Resveratrol regulates muscle fiber type conversion via miR-22-3p and AMPK/SIRT1/PGC-1α pathway.

Journal of Nutritional Biochemistry, 2019
This study investigated the effects of resveratrol and miR-22-3p on muscle fiber type conversion in mouse C2C12 myotubes. Here we showed that resveratrol significantly increased the protein level of slow myosin heavy chain (MyHC) and the activities of ...

Muscle fiber‐type distribution, fiber‐type‐specific damage, and the Pompe disease phenotype

Journal of Inherited Metabolic Disease, 2012
AbstractPompe disease is a lysosomal storage disorder caused by acid α‐glucosidase deficiency and characterized by progressive muscle weakness. Enzyme replacement therapy (ERT) has ameliorated patients’ perspectives, but reversal of skeletal muscle pathology remains a challenge.

Muscle Fiber Types

Orthopedics, 1985
ABSTRACT; Muscle fiber can be typed according to histologic, biochemical, neurophysiology, and ultrastructural differences. The relationship between muscle fiber typing and clinical areas of investigation is summarized. Genetic factors are largely responsible for the distribution of main muscle fiber types.

Fiber Types in Mammalian Skeletal Muscles

Physiological Reviews, 2011
Mammalian skeletal muscle comprises different fiber types, whose identity is first established during embryonic development by intrinsic myogenic control mechanisms and is later modulated by neural and hormonal factors. The relative proportion of the different fiber types varies strikingly between species, and in humans shows significant variability ...

Mechanical, flexural and microstructural properties of cement-tailings matrix composites: Effects of fiber type and dosage

Composites Part B: Engineering, 2019
Cement-tailings matrix composites (CTMC) have problems such as high brittleness and poor crack resistance when subjected to high stresses corresponding to large depths.

Effective fiber type investigation on the shear behavior of ultrahigh-performance fiber-reinforced concrete beams

Advances in Structural Engineering, 2019
In this study, the effects of different fiber types on shear behavior (cracking pattern, shear cracking strength, ultimate shear strength, and post-cracking deformability) of ultrahigh-performance fiber-reinforced concrete beams were investigated ...

Effects of fiber type, volume fraction and aspect ratio on the flexural and acoustic emission behaviors of steel fiber reinforced concrete

Construction and Building Materials, 2018
This paper investigates the effects of fiber type, volume fraction and aspect ratio on the flexural and acoustic emission (AE) behaviors of steel fiber reinforced concrete (SFRC) using four-point bending tests. Three types of steel fibers, i.e., straight,

Congenital Fiber-Type Disproportion

Seminars in Pediatric Neurology, 2011
Congenital fiber-type disproportion is a form of congenital myopathy that may be best viewed as a syndrome rather than as a formal diagnosis. The central histologic abnormality is that type 1 fibers are consistently smaller than type 2 fibers by at least 35%-40%.
