Alterations in thin filament length during postnatal skeletal muscle development and aging in mice
Frontiers in Physiology, 2014 The lengths of the sarcomeric thin filaments vary in a skeletal muscle-specific manner and help specify the physiological properties of skeletal muscle.

Kinetic mechanism of myofibril ATPase
Biophysical Journal, 1994 The kinetic mechanism of myofibril ATPase was investigated using psoas and mixed back muscle over a range of ionic strengths. Myofibrils were labeled with pyrene iodoacetamide to measure the rate constants for the binding of ATP and formation of the weakly attached state.

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

The Regulation of Muscle Structure and Metabolism by Mio/dChREBP in Drosophila. [PDF]
PLoS ONE, 2015 All cells require energy to perform their specialized functions. Muscle is particularly sensitive to the availability of nutrients due to the high-energy requirement for muscle contraction.

Animal Research and One Health, EarlyView.ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Mechanism of Oleic Add-Induced Myofibril Disassembly in Rat Cardiomyocytes [PDF]
, 2008 This study investigated the mechanism of oleic acid (OA)- induced disassembly of myofibrils in cardiomyocytes. OA treatment disrupted myofibrils, as revealed by the disorganization of several sarcomeric proteins.

Cytoskeleton, EarlyView.ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle
Developmental Dynamics, EarlyView.Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Theoretical considerations on myofibril stiffness
Biophysical Journal, 1997 A discrete model of the interaction between individual myofilaments was developed to study the stiffness of a sarcomere for the case in which filament compliance is not negligible. Our model retains, in the limit, the characteristics of the previously published model by Ford et al. (Ford, L. E., A. F. Huxley, and R. M. Simmons. 1981.
