Permanent facial paralysis is a catastrophic event for involved patients. In long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. But its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. This article advocate a new modification for resolving this problem with concomitant el...
Preferential atrophy of Type-II muscle fibres occurs in several clinical situations, including cachexia, muscle disuse, chronic glucocorticoid treatment, remote neoplasia, and sometimes as an aspect of recent-denervation. For the patient, the Type-II atrophy itself might be unfavourable (as a glucocorticoid side-effect) or favourable (survivalistic via the muscle-alanine liver-gluconeogenesis p...
Metabolic abnormalities develop in various chronic diseases and lead to progressive catabolism with decrements in the skeletal musculature that result in muscle atrophy. We investigated pathways of skeletal muscle proteolysis using an experimental model of chronic left-ventricular dysfunction. Skeletal muscle atrophy developed in wild-type mice 12 weeks following myocardial infarction accompani...
Powers SK, Kavazis AN, McClung JM. Oxidative stress and disuse muscle atrophy. J Appl Physiol 102: 2389–2397, 2007; doi:10.1152/japplphysiol.01202.2006.—Skeletal muscle inactivity is associated with a loss of muscle protein and reduced forcegenerating capacity. This disuse-induced muscle atrophy results from both increased proteolysis and decreased protein synthesis. Investigations of the cell ...

[Purpose] To study muscle atrophy, the muscle atrophy model mice have been used frequently. In particular, cast immobilization is the most common method to induce muscle atrophy. However, it is time consuming and often causes adverse events including skin injury, edema, and necrosis. The present study, we developed a hook-and-loop fastener (Velcro) immobilization method as a new, simple, and le...
Skeletal muscle atrophy refers to the decline in muscle mass and strength that occurs under various conditions, including aging, starvation, cancer and other cachectic diseases. Muscle atrophy caused by aging, known as sarcopenia, primarily occurs after 50 years of age. Muscle atrophy‑related genes, including atrogin1/muscle atrophy F‑box (MAFbx) and muscle RING finger 1 (MuRF1), are expressed ...
BACKGROUND Denervation-induced skeletal muscle atrophy results in significant biochemical and physiological changes potentially leading to devastating outcomes including increased mortality. Effective treatments for skeletal muscle diseases are currently not available. Muscle-specific miRNAs, such as miR-206, play an important role in the regulation of muscle regeneration. The aim of the presen...
In this study, the role of the calcineurin pathway in skeletal muscle atrophy and atrophy-reducing interventions was investigated in rat soleus muscles. Because calcineurin has been suggested to be involved in skeletal and cardiac muscle hypertrophy, we hypothesized that blocking calcineurin activity would eliminate beneficial effects of interventions that maintain muscle mass in the face of at...
Atrophy developing in the quadriceps femoris muscle following knee injury is one of the serious problems not only in the field of orthopedics but also of rehabilitation. However the pathogenesis of this atrophy has not yet been elucidated. The author therefore produced a complex ligament injury model using the knee joints of rats in order to study the pathogenesis of this atrophy. After severin...
