Mouse Models for Thin Filament Disease
2008Thin filament integrity is important for the ordered structure and function of skeletal muscles. Mutations within genes that encode thin filament and thin filament-associated proteins can cause muscle disruption, fiber atrophy and alter fiber type composition, leading to muscle weakness.

Capillary thinning of polymeric filaments
Journal of Rheology, 1999The capillary thinning of filaments of a Newtonian polybutene fluid and a viscoelastic polyisobutylene solution are analyzed experimentally and by means of numerical simulation. The experimental procedure is as follows. Initially, a liquid sample is placed between two cylindrical plates.

Thin filament interferometric microphone
Journal of Applied Physics, 1980A thin filament which follows the motion of a gas is used to measure small pressure fluctuations for photoacoustic spectroscopy. Optical heterodyne detection of laser radiation scattered from the filament provides a sensitive measurement of its displacement.

Thin Threads of Solar Filaments
Solar Physics, 2005High-resolution images obtained in Hα with the new Swedish Solar Telescope at La Palma, Spain, have been used for studies of fine-scale threads in solar filaments. The widths of the thin threads are ≤0.3 arcsec. The fact that the width of the thinnest threads is comparable to the diffraction limit of the telescope of about 0.14 arcsec, at the ...

Thin filament structure and activation
Proceedings, annual meeting, Electron Microscopy Society of America, 1989Skeletal muscle contraction is triggered by the release of calcium ions from the sarcoplasmic reticulum of the myofibrils. Troponin and tropomyosin in the thin (actin-containing) filaments act together as the transducer of this signal. Evidence from reconstruction of electron images of negatively stained samples and from x-ray diffraction studies of ...

Investigations into the Pathobiology of Thin-Filament Myopathies
2008Mutations in actin and tropomyosin, identified in patients with myopathic disease have been used in tissue culture models and functional studies with a view to understand how these mutations impact on skeletal muscle structure and function and result in muscle weakness.

Variation of thin filament length in heart muscle
Nature, 1977ALTHOUGH the length dependence of force generation by heart muscle has been attributed to the degree of overlap of thin and thick filaments within the sarcomere, the required accurate values of the lengths of cardiac thin filaments have not been available.

Thin Filament-Mediated Regulation of Cardiac Contraction
Annual Review of Physiology, 1996Cardiac and skeletal muscle contraction are activated by Ca2+ binding to specific regulatory sites on the striated muscle thin filament. The thin filament is a large allosteric assembly, containing multiple copies of actin, tropomyosin, and the three troponin subunits (troponin C, troponin I, and troponin T).

Thin Filament Structure and Regulation
1981Actin must rank as one of the most ubiquitous proteins in nature. Thin filaments consisting largely of actin molecules have been found to occur in all of the different muscle types that have so far been studied. In addition, actin molecules with virtually identical properties to those in muscle have been found in a variety of non muscle cells, ranging ...
