Age-related changes in muscle mass (sarcopenia) and functional properties are the result of a very complex hierarchical system of basic cell aging processes and cell adaptive responses. A basic aging mechanism pertains to mitochondrial production of free radicals and their associated secondary effects.

Imaging of Skeletal Muscle [PDF]
Rheumatic Disease Clinics of North America, 2011 Various diagnostic imaging techniques such as sonography, computed tomography, scintigraphy, radiography, and magnetic resonance imaging (MRI) have made possible the noninvasive evaluation of skeletal muscle injury and disease. Although these different modalities have roles to play, MRI is especially sensitive in the diagnosis of muscle disorders and ...

It is rare for lymphoma to present as a primary muscle lesion. The computed tomography (CT) features are described in three cases. Muscle involvement was the only manifestation of lymphoma in two, and in all three cases, contrast enhancement of the soft tissue mass occurred.

The most common tumors arising in muscle are soft tissue sarcomas, fibromatoses, and hemangiomas. Rhabdomyosarcoma is primarily a tumor of childhood and adolescence and arises most commonly in extramuscular sites. Most intramuscular rhabdomyosarcomas are alveolar.

Regeneration of skeletal muscle
Cell and Tissue Research, 2011Skeletal muscle has a robust capacity for regeneration following injury. However, few if any effective therapeutic options for volumetric muscle loss are available. Autologous muscle grafts or muscle transposition represent possible salvage procedures for the restoration of mass and function but these approaches have limited success and are plagued by ...

The paper is devoted to the most complicated aspects of low back pain. The differences between specific and nonspecific low back pain using the "red flags" system is highlighted. The authors consider the causes of pain chronification (the "yellow flags" system) and the necessity of using a biopsychosocial model.

Skeletal muscle channelopathies
Journal of Neurology, 2002Ion channelopathies have common clinical features, recurrent patterns of mutations, and almost predictable mechanisms of pathogenesis. In skeletal muscle, disorders are associated with mutations in voltage-gated Na(+), K(+), Ca(2+), and Cl(-) channels leading to hypoexcitability, causing periodic paralysis and to hyperexcitabilty, resulting in myotonia

Intramuscular hemangiomas are rare benign tumors, making up 0.8% of all hemangiomas. They are of interest to the surgeon because their location may present considerable therapeutic challenge since radiographic work-up of the soft- tissue mass by magnetic resonance imaging (MRI) may be suspicious for malignancy.

Current Opinion in Neurobiology, 2002
Recent studies challenge the view that signals provided by motor neurons are required to activate subsynaptic nuclei and induce postsynaptic specializations in developing skeletal muscle. New findings show that acetylcholine receptor genes are expressed and that acetylcholine receptor clusters form preferentially in the prospective synaptic region of ...

Vasodilation in skeletal muscle
American Journal of Physiology-Legacy Content, 1963Blood flow was studied in dog hind-limb muscle isolated except for femoral and sciatic nerves. At constant perfusion pressure, elevation of aortic pressure produced by blood transfusion or intravenous epinephrine administration elicited a three- to fourfold increase in blood flow in perfused muscle.
