Free ureteral replacement in rats: regeneration of ureteral wall components in the acellular matrix graft. [PDF]
, 1997 ObjectivesTo evaluate ureteral replacement by a free homologous graft of acellular matrix in a rat model.MethodsIn 30 male Sprague-Dawley rats, a 0.3 to 0.8-cm midsegment of the left ureter was resected and replaced with an acellular matrix graft of ...

Weekly Versus Monthly Testosterone Administration On Fast and Slow Skeletal Muscle Fibers in Older Adult Males [PDF]
, 2014 Context: In older adults, loss of mobility due to sarcopenia is exacerbated in men with low serum T. T replacement therapy is known to increase muscle mass and strength, but the effect of weekly (WK) vs monthly (MO) administration on specific fiber types

Rinsho Shinkeigaku, 2012 Muscle fibers have been classified into two major forms of red (slow twitch) and white (fast twitch) muscles. The red muscle utilizes lipid as energy source through mitochondrial metabolism and function to sustain the position against gravity (sometimes called as antigravity muscle). Under microgravity the red muscle is selectively involved.

Skeletal Fiber Type in Muscle Pain and Dysfunction
BiomedicinesDifferent types of skeletal muscle fibers display marked heterogeneity in metabolic, mechanical, and regenerative properties. However, their role in chronic musculoskeletal pain remains insufficiently integrated into clinical models.

Effects of Low Cell pH and Elevated Inorganic Phosphate on the pCa-Force Relationship in Single Muscle Fibers at Near-Physiological Temperatures [PDF]
, 2014 Intense muscle contraction induces high rates of ATP hydrolysis with resulting increases in Pi, H+, and ADP, factors thought to induce fatigue by interfering with steps in the cross-bridge cycle.

Aging of Skeletal Muscle Fibers [PDF]
Annals of Rehabilitation Medicine, 2015 Aging has become an important topic for scientific research because life expectancy and the number of men and women in older age groups have increased dramatically in the last century. This is true in most countries of the world including the Republic of Korea and the United States. From a rehabilitation perspective, the most important associated issue

A histochemical study of the red and white muscle fibers Part II. Activity of the cytochrome oxidase in muscle fibers [PDF]
, 1958 From the histochemical studies of cytocyrome oxidase on the striated muscles of the cats and mice, the following results have been obtained. The three types of muscle fibers are distinguishable by the activity of cytochrome oxidase from each other as by ...

European Journal of Translational Myology, 2013 It has long been recognized that histological changes observed in aging muscle suggest that denervation contributes to muscle deterioration and that disuse accelerates the process while running activity, sustained for decades, protects against age ...
