Reliability of muscle thickness measurements in ultrasonography

International Journal of Rehabilitation Research, 2020
This study aims to clarify some of the issues associated with the reliable measurement of muscle thickness on ultrasonographic images of the musculoskeletal system, namely the repeatability of measurements in different time frames, the effect of body side selection, and the effect of scan orientation.

Thick Filaments in Unstretched Mammalian Smooth Muscle

Nature New Biology, 1971
THE controversy concerning the organization of myosin in mammalian smooth muscle was reviewed (Nature New Biology, 231, 225; 1971) at a time when the studies of Rice's laboratory and our own demonstrated a regular, quasi-rectangular array of thick filaments in guinea-pig taenia coli (TC) and rabbit portal-anterior mesenteric vein (MV), and, further ...

Thick filaments and paramyosin of annelid muscles

Journal of Ultrastructure Research, 1976
Thick filaments from annelid muscle were observed by positive and negative staining of the glycerinated sample, which was homogenized in a relaxing medium containing ATP. The preservation of myosin on the filament surface was strictly related to very high concentration of ATP (12 m M .). The 144 A periodicity was scarcely visible.

Ciliary muscle thickness in adults with Down syndrome

Ophthalmic and Physiological Optics, 2022
AbstractPurposeThe relationship between ciliary muscle thickness (CMT), age and refractive error was investigated to determine if CMT, like other anterior ocular anatomy, differs in adults with Down syndrome (DS).MethodsThe CMT of 33 adults with DS was imaged using anterior segment optical coherence tomography.

Sequential disassembly of vertebrate muscle thick filaments

Journal of Molecular Biology, 1980
Abstract Native thick filaments from rabbit psoas muscle have been sequentially dissolved by incremental rises in salt concentration. Three quite separate stages of depolymerization can be detected; these presumably reflect constraints imposed on the disassembly process by variations in the packing of myosin and by the presence of other thick ...

Structure of Limulus telson muscle thick filaments

Journal of Molecular Biology, 1981
Abstract Computer analysis of electron micrographs of negatively stained thick filaments isolated from the telson levator muscle of the horseshoe crab ( Limulus polyphemus ) has shown that they have a four-stranded helical structure. The repeating units along each helix have a bent extended shape (measuring approximately 20 nm × 8 nm × 8 nm) and are ...

Ultrasound assessment of hamstring muscle size using posterior thigh muscle thickness

Clinical Physiology and Functional Imaging, 2014
SummarySeveral studies have investigated the relationship between ultrasound‐measured muscle thickness (MT) and individual muscle cross‐sectional area (CSA) and muscle volume (MV) in extremity and trunk muscles; however, the hamstring muscle has not been studied.

Muscle capillary basement membrane thickness in lipoatrophic diabetes

Research in Experimental Medicine, 1977
A 21 years old female patient with lipoatrophic diabetes, a distinct syndrome of insulin resistant diabetes mellitus, loss of subcutaneous fat, hepatosplenomegaly, hyperlipidemia, increased basal metabolic rate, subvalvular aortic stenosis and cystic bone lesions is described. She exhibited all clinical signs of diabetic microangiopathy.

PACKING OF MYOSIN MOLECULES IN MUSCLE THICK FILAMENTS

Cell Biology International, 2000
AbstractThe backbone of the myosin filament is an aggregate of α‐helical coiled coil myosin rods. Its surface forms a three‐stranded helix composed of myosin heads. Currently there is no adequate model to describe the organization of the myosin filament.

Variation and Impact of Muscle Thickness

1978
Muscles largely differ in thickness due to the variation of their weight during growth, which results mainly from an increase in the diameter of muscle fibres. With increasing thickness, the morphological aspects of the perimysium network is changed. The thickness each muscle may present depends on the dimensions of the skeleton.
