Skeletal muscle mitochondria in health and disease

Cell Calcium, 2021
Mitochondrial activity warrants energy supply to oxidative myofibres to sustain endurance workload. The maintenance of mitochondrial homeostasis is ensured by the control of fission and fusion processes and by the mitophagic removal of aberrant organelles.

Mitochondria: Muscle Morphology

2019
Mitochondrial genetic defects can potentially affect any cell, tissue, and organ; however, they are often referred to as mitochondrial encephalomyopathies to indicate that skeletal muscle and brain tissue, due to their high energy demand, are most often involved.

The oxidase systems of Ascaris-muscle mitochondria

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1970
Abstract 1. The oxidase systems of Ascaris-muscle mitochondria were investigated by polarographic and spectroscopic techniques. 2. Spectrophotometric studies at −196° revealed that Ascaris-muscle mitochondria contained low levels of substrate-reducible a-, b- and c-type cytochromes.

Giant Mitochondria in Human Muscle With Inclusions

Archives of Neurology, 1967
RECENTLY, two reports have been published on myopathies characterized primarily by abnormalities of mitochondria. In the first, Luft et al1described a severely hypermetabolic patient with loosely coupled oxidative phosphorylation in mitochondria and, in the second, Shy et al2described pleoconial and megaconial conditions, both related to aberrent ...

Volume rendering of heart muscle mitochondria

Proceedings of the 2011 companion on High Performance Computing Networking, Storage and Analysis Companion, 2011
Volumetric representations of electron microscopy reveal nanometer structural features of the mitochondrion. These organelles are the cell's 'power plant,' generating most of the adenosine triphosphate - the main source of chemical energy for a cell. Visualized here are the mitochondria present in human heart muscle.

Oxidative phosphorylation in Moniezia muscle mitochondria

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract 1. 1. Mitochondria isolated from Moniezia expansa , an intestinal parasitic tapeworm, have the same structural characteristics as the classical mammalian aerobic mitochondria by having clearly defined outer and inner membranes, outer compartment and intracristal spaces, and elementary particles attached to the mitochondrial cristae. 2.

Neuromuscular Disorders with Abnormal Muscle Mitochondria

1980
Publisher Summary Mitochondria are the site of oxidative phosphorylation of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). The mechanical work of muscle fibers—that is, shortening of myofibrils, depends on an adequate supply of ATP, and metabolic disorders of mitochondria can be assumed to impair the function of the muscle fiber.

Familial Myopathy With Abnormal Muscle Mitochondria

Archives of Neurology, 1968
DURING the past ten years several myopathies with unusual microscopic changes in muscle have been described. 1-3 Shy and Magee presented the original report of a familial myopathy, "central core disease," characterized by weakness and hypotonia from birth and a characteristic morphologic abnormality in the center of muscle fibers.

Mitochondria in Skeletal Muscle

Exercise and Sport Sciences Reviews, 2008
Apoptosis is an essential process that plays a critical role in both tissue development and maintenance. Apoptosis has been shown to be involved in skeletal muscle atrophy resulting from chronic muscular disuse, sarcopenia, and mitochondrial myopathies. Exercise may attenuate some of the proapoptotic adaptations that occur during these conditions. This

Mitochondria in Muscle and Exercise

2017
This chapter will discuss the role of mitochondria in muscle, particularly the effect of acute and chronic exercise. The focus will be on human studies. A general overview of mitochondrial structure and function will be followed by a discussion of the diverse techniques used to measure mitochondrial function.
