Muscle structure and function in older adults with a rotator cuff tear
… age. Symptoms of a rotator cuff tear include muscle atrophy, fatty infiltration, decreased strength, and a loss of functional ability. However, a healthy aging process is also associated with atrophy, reduced strength, and declines in physical function. The goals of this dissertation were to …

Exercise tolerance and skeletal muscle structure and function in patients with chronic obstructive pulminary disease
… cardiac and renal failure suffer from skeletal muscle (SM) abnormalities that impair exercise tolerance and (ii) patients with chronic obstructive pulmonary disease (COPD) may have metabolic and functional abnormalities of SM. However, no studies have conducted a detailed investigation of SM …

Exercise tolerance and skeletal muscle structure and function in patients with severe chronic heart failure
… of the peripheral circulation and skeletal muscle function as possible factors limiting the exercise tolerance of patients with CHF. However there are few studies describing both the structural and functional abnormalities in the skeletal muscle of patients with CHF. In the first study of …

An evaluation of gastrocnemius muscle structure and function in endurance runners and low physical activity individuals
… runners. The gastrocnemius is the main muscle used for propulsion in running, and may be at risk for injury due to its morphology. In previous studies, changes in the morphology and architecture of the gastrocnemius muscle have been evident following training, but it is unclear whether …

Gastrocnemius muscle structure and function in habitually resistance-trained marathon runners and traditionally running-trained marathon runners: a comparative analysis
… identified as one of the most commonly injured structures during running. Running training causes an overload on muscle and stimulates a physiological adaptation to create a training response. Specific adaptations in metabolic and physiological function of a muscle may be further achieved …

GENERATION OF FULL-LENGTH WILD-TYPE GATA4 PROTEIN AND CHARACTERIZATION OF ITS BINDING TO UNC-45 DOMAINS
<p>Striated muscle UNC-45 (SM UNC-45) protein acts as a chaperone for cardiac and skeletal muscle myosins; regulating their folding, assembly into thick filaments, interaction with other sarcomeric proteins, and degradation. GATA4 is an important transcription factor that regulates the expression …

Imaging displacement and strain in the medial gastrocnemius muscle during ankle-joint motion using 2D-ciné DENSE MRI
Skeletal muscle structure has been defined on both macro and microscopic levels by gross dissection, light- and electron-microscopy. The basic physiological building blocks involve the electromechanical coupling between interlinking actin and myosin fibres. Detailed intramuscular behaviour during …

Using a bio-inspired model to understand the evolution of the remora adhesive disk
… disk includes a complex and integrated bone and muscle structure that enhances the adhesion of the remora on rough surfaces. Manmade adhesives often fail on wet, compliant surfaces, which can result in poor performance when attaching sensors in medical, defense, and research situations. However, …

Analysis of a Proposed Cell Binding Site on Caenorhabditis Elegans Collagen Type Iv
… cell migration and binding. C. elegans body wall muscle col IV consists of two alpha 1 chains and one alpha 2 chain. The human col IV molecule has a cell binding site (CBS) composed of aspartate (D) on each alpha 1 chain and arginine (R) on the alpha 2 chain that form a D-D-R sequence recognized …

A comparative study of the structure and biochemical activity of flight muscles from several insect species
… studies were conducted with the flight muscles and mitochondria of several insect species to determine any correlation which exists between muscle structure and the metabolic activity of their mitochondria. Light microscopic examinations were used in the subcellular observations of these …
