We observed a temporarily increased intramuscular availability of free Gln that could have influenced cellular processes in skeletal muscle. (nature.com)
We all know that elevated training intensity requires an optimal state of mind, but many fail to consider that superior workouts also rely on having an optimal muscle cellular environment. (drdwaynejackson.com)

What actually is skeletal muscle hypertrophy? (blogspot.com)
Analogously, you would expect your muscle fibers to "hypertrophy" (from mechanical overload and constant nutrient abundance) until they are "ready to burst" and then divide and form new muscle fibers . (blogspot.com)

Local tumors (fibrosarcoma, osteosarcoma, mast cell tumors) can invade adjacent muscle. (4build.eu)

The addition of BrdU-positive myonuclei increased from 1 per 1000 myofibers in cross sections of control muscles to 2 to 3 per 100 myofibers in the resected muscles. (arvojournals.org)
Both active and passive stretch of the rectus muscles produced by strabismus surgery dramatically upregulated the processes of satellite cell activation, integration of new myonuclei into existing myofibers, and concomitant upregulation of immature myosin heavy chain isoforms. (arvojournals.org)
3 When a muscle is injured, this specialized cell population becomes activated, divides, and either repairs damaged fibers or forms new myofibers. (arvojournals.org)

mTOR then increases the translation of muscle-cell ribosomal proteins that increase ribosome biogenesis, which is the literal production of proteins. (tigerfitness.com)

Scientists think that a low-calorie diet and exercise-induced proteins (Sterol regulatory element-binding protein) cause the high levels of IMTG in athletes' skeletal muscle. (wikipedia.org)

Muscle growth of low birth weight (LBW) piglets may be improved with adapted nutrition. (nature.com)
Our previous studies showed that Gln had the potential to increase muscle fiber size in piglets 16 , but the mechanism was not clear. (nature.com)

Intramuscular myxoma is a fairly rare benign tumor accounting for 3% of benign tumors. (jotsrr.org)

Conversely, inactivity markedly decreases collagen turnover in both tendon and muscle. (fasciaguide.com)

Researchers believe that the improved efficiency of trained skeletal muscles prevents the development of insulin resistance. (wikipedia.org)

Abnormal tightening or contracture of the shoulder muscle (infraspinatus) is a muscle disease that affects one or both shoulders. (4build.eu)
Fibrous replacement of the deltoid muscle: a remediable cause of abduction contracture of the shoulder in scleroderma. (medscape.com)

Intramuscular fat (also known as intramuscular triglycerides, intramuscular triacylglycerol, or intramyocellular triacylglycerol [IMTG]) is located inside skeletal muscle fibers. (wikipedia.org)

Myofibrils are cylindrical structures made up of repeated units known as sarcomeres that cause the striated appearance of muscle when meat is observed by electron microscopy. (earthwormexpress.com)

Finally, HIF-1α overexpression was confirmed in the muscle biopsies and in some RIG-I positive perifascicular muscle fibres but not in controls. (nih.gov)
The results of the 1997 muscle biopsies by Jurimäe et al. (blogspot.com)
Most muscle biopsies exhibit a constellation of pathologic findings that must be synthesized to arrive at a diagnosis. (medscape.com)

This procedure results in rotation of the globe toward the resected muscle, increased resting tension across the agonist-antagonist pair, and stretching of the elastic components of the muscles. (arvojournals.org)
This thinning is also primarily a dermal change, with loss of elastic fibers, epithelial appendages, and ground substance. (medscape.com)

Absorbs - stomach and intestinal lining (gut) Filters - the kidney Together these sheets and fibers and known as muscles, and control the movements of an organisms as well as many other contractile functions. (4build.eu)
Comprised of leucine, isoleucine, and valine, these three little amino acids effectively control the rate at which your muscle grows (hypertrophies), its contractile force, its endurance, and so on - to say they are massively important is an understatement. (tigerfitness.com)
This correlated with an increased contractile strength of the muscles, indicating improved muscle power. (recmalabs.com)

The use of visual biofeedback has demonstrated greater increases in muscle activation and greater improvements in exercise form compared to verbal and audio feedback. (mtrigger.com)
Or would you have expected that bodybuilding is a sport that is characterized by a loss in highly glycolytic type IIb fibers and increases in both the intermediate type IIa, as well as the "endurance type" slow-twitch muscles? (blogspot.com)

These and other functions of the muscle spindles, as well as the tension-sensitive organs in tendons, will be discussed. (humanneurobiology.com)

Theoretically, the possibilities include (1) a primary T-cell mediated autoimmune response causing muscle damage, (2) a primary degenerative process involving abnormal protein processing leading to a secondary inflammatory response, and (3) separate and independent immune and degenerative processes caused by an external trigger. (medscape.com)
