Das Muskelfäserchen (Muskelfibrille, Myofibrille, Myofibril)

1957
Ganz wie die Muskelfaser hat auch die Muskelfibrille eine doppelte Gliederung, eine axiale und eine transversale. Die transversale oder quere Gliederung (parallel mit der Querachse) wird dargestellt durch die verschiedenen von der Lichtmikroskopie her bekannten Bander und Zonen, die fur die Querstreifung aller quergestreiften Muskulatur verantwortlich ...

Elongation of cross-striated myofibrils

Biochimica et Biophysica Acta, 1956
Abstract When myofibrils isolated from the indirect flight muscles of Calliphora were treated under the microscope with freshly-prepared crude suspensions of sarcosomes from the same muscles they elongated by about 4% and then contracted when treatment ceased; several cycles of elongation and contraction could be brought about. Evidence is given that

Myofibrils, Intercalated Disk

2010
Cardiac muscle belongs to the striated types of muscle containing the same arrangements of myofilaments as skeletal muscle. However, unlike in skeletal muscle no syncytia are built but cylindrical muscle cells containing one large cube-shaped nucleus in central position are arranged end to end and join with adjacent cells at special attachment sites ...

Gelation of Turkey Breast and Thigh Myofibrils: Changes During Isolation of Myofibrils

Journal of Food Science, 1993
ABSTRACT The relationship between functional properties of meat and myofibrils was examined for turkey breast and thigh by determining gel‐forming ability of proteins at each step in a myofibril isolation procedure. Physical properties of thermally induced gels (70°C for 30 min) were determined by torsional fracture analysis.

Volume changes in isolated myofibrils

Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964
Volume changes in glycerol-extracted myofibrils were studied. The effect of pH, ion content and ATP concentration on the change in volume was determined. A volume change greater than that attributed to ATP dephosphorylation was observed. The magnitude of the volume change of the entire system was 10−3 cm3 whereas that due to dephosphorylation was 10−6 ...

Binding of filamin isoforms to myofibrils

Journal of Muscle Research & Cell Motility, 2000
Two filamin isoforms were purified from bovine tissues and characterized. Muscle filamin and nonmuscle filamin had different SDS gel mobilities, proteolytic digestion patterns, myofibrillar binding distributions and myofibril binding affinities. The muscle specific filamin had an apparent molecular weight of 265 kDa and bound primarily to the Z-lines ...

Preparation of myosin rods from myofibrils

Biochemical and Biophysical Research Communications, 1973
Abstract A simple and fast procedure is described for producing myosin rods with a good yield. The method is based on the digestion of myofibrils by soluble papain. After purification by alcoholic precipitation and gel filtration, rod segments exhibited physical-chemical parameters identical to previously reported data.

[2] Preparation of myofibrils

1982
Publisher Summary A variety of procedures are available for the preparation of myofibrils, and this chapter presents four of these that include myofibrils from fresh rabbit psoas muscle, myofibrils from glycerinated psoas muscle, myofibrils in bulk from fresh muscle, and myofibrils in bulk from stored muscle..

To the heart of myofibril assembly

Trends in Cell Biology, 2000
One of the most fascinating examples of cytoskeletal assembly is the myofibril, the contractile structure of striated (i.e. skeletal and cardiac) muscle. Myofibrils are composed of repeating contractile units known as sarcomeres, perhaps the most highly ordered macromolecular structures in eukaryotic cells.

Adaptation in der Myofibrille

physiopraxis, 2004
Muskelkater – wodurch entsteht er? Muskelschaden oder Remodellierungsprozess der Myofibrillen? Und wie kann man ihn behandeln? Wissenschaftler aus aller Welt diskutieren Pathogenese und Therapie. Wilhelm E. Kraft hat für physiopraxis die aktuelle Literatur recherchiert und die Studienergebnisse auf den Punkt gebracht.
