Artificial muscle morphology : structure/property relationships in polypyrrole actuators
… Our detailed understanding of polypyrrole morphology at different lengthscales provides valuable insight to the mechanisms of polypyrrole actuation, and has helped us process polypyrrole more intelligently for improved electroactive devices.

Skeletal muscle morphology and function in former elite distance runners : a 20 year follow-up
… and functional characteristics of skeletal muscle. Sixty men (current age = 49.2 ± 2.4 yr.) were first studied between 1966-1974 when they were all highly trained. Based on their training regimens in the interim between testing, subjects were described as highly trained (HI), fitness trained …

IMPLICATIONS OF AGING AND DEGENERATIVE ROTATOR CUFF TEARS FOR UPPER LIMB MUSCLE MORPHOLOGY, STRENGTH, AND FUNCTION
… methods that enhance our understanding of how muscle morphology relates to strength. Traditional motion capture combined with a musculoskeletal modeling approach were used to evaluate shoulder strength requirements necessary for successful task completion and determine how age- and rotator cuff …

A comparison of muscle damage, soreness, morphology, T2 changes and running performance following an ultramarathon race
Background: Exercise induced muscle damage collectively describes the response to strenuous or unaccustomed exercise. It is well - established that endurance running causes muscle damage. Indirect indicators of muscle damage include the loss of muscle strength, increased levels of muscle proteins, …

Skeletal muscle structure and metabolism in chronic heart failure
… exercise intolerance. Maladaptations in skeletal muscle appear to be a likely reason for the limited exercise tolerance. In study I, exercise tolerance and skeletal muscle metabolism and morphology were examined in 17 CHF patients and eight healthy similarly aged sedentary control subjects. In …

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 …

Investigation of spine loading to understand vertebral fractures
… of vertebral compressive loading and trunk muscle activity were highly correlated with previously collected in vivo measurements of pressure, vertebral compression from telemeterized implants, and trunk muscle myoelectric activity from electromyography. To gain insights into how individual …

Coccydynia in Taiwanese women: biomechanical and physiological study
… had thicker resting transversus abdominis (TrA) muscles than healthy participants but showed less thickness change during a functional task, indicating reduced ability to contract the muscle. Differences between patients and healthy groups from motion analysis and EMG studies were found and …

Longitudinal variation in the axial muscles of snakes
The axial muscles of snakes are notable for having long tendons within individual segments that span several vertebrae. Consequently, muscles that extend anteriorly have a constraint on their length as their origins are located closer to the skull. However, this and other aspects of longitudinal …

Functional myology of the primate head and neck with implications for hominin evolution
… relied upon untested hypotheses linking nuchal muscle form and function to bony morphologies. This thesis addresses the gap in knowledge of variation in the primate nuchal musculature and its relationship to positional behaviors through the use of gross cadaveric dissections and in silico …

The adaptive response of humans to exercise: Impact of exercise intensity, fibre-type specific responses and molecular patterns of response
… in aerobic performance, aerobic capacity and muscle phenotype following high-intensity interval training (HIT) or endurance exercise (END). The acute molecular response (fibre recruitment and signal activation) and training-induced adaptations in aerobic capacity, aerobic performance, and …

High-intensity interval eccentric cycling: Acute and chronic effects
… <Study 2>; and iii) aerobic performance, muscle morphology and function after 8-week interval eccentric versus concentric cycling training <Study 3>. Study 1: Nine men and two women (20-48 y) performed an incremental concentric and eccentric cycling test. Peak power output (PPO) was 53% …

The extracellular matrix of the nematode Caenorhabditis elegans : a model to study the role of cell-matrix interaction in animal development.
… transgenic rescue animals displayed defects in muscle morphology, gonad migration, high male number, and tail morphology. Further analyses revealed that males from pat-3(Y804E) transgenic mutant and him-4/hemicentin share similar phenotypes such as abnormal gonads and unsuccessful mating, …

Assessment of Ocular Accommodation in Humans
… tomographer (AS-OCT) was used to image the morphology of the ciliary muscle during accommodation. The accuracy of ciliary muscle measurements was improved when using reference points on the sclera to align the AS-OCT scan. The use of a ciliary muscle area metric demonstrated poor …

Arthrogryposis. Causes, Consequences and Clinical Course in Amyoplasia and Distal Arthrogryposis
… occurring condition with hypoplastic muscles and joint contractures. Distal arthrogryposis (DA) syndromes are often hereditary, and joint involvement is predominantly in hands and feet. Arhrogryposis with CNS involvement includes chromosomal and other syndromes. Aims. The purpose of …

The reproductive seasonality and flight capability of Sitona discoideus Gyllenhal (Coleoptera: Curculionidae) and its pattern of larval establishment in Canterbury lucerne
… the weevil's reproductive condition and flight muscle morphology were monitored by dissection. This work confirmed that the univoltine adult weevils entered aestivatory diapause some three to four weeks after the eclosion of the new generation in December-January each year. Flight to aestivation …

FROM MUSCLE TO MEAT: MORPHO-FUNCTIONAL FOUNDATIONS FOR APPLICATIVE ASPECTS.
The transformation of muscle into meat is a biologically complex mechanism with deep implications for animal physiology, the meat industry, and food science. Understanding the morpho-functional foundations of this process -including structural, cellular, and molecular characteristics of muscle …
