Studies on the 14.5 nm Meridional X-Ray Diffraction Reflection During Length Changes of Intact Frog Muscle Fibres

The intensity of the 14.5 nm meridional reflection (M3) from activated skeletal muscle fibres was studied in both single fibres and fibre bundles during the imposition of length changes. During shortening at s...

Time-Resolved Equatorial X-Ray Diffraction Measurements in Single Intact Muscle Fibres

Equatorial X-ray diffraction techniques have been successfully applied to the intact single muscle fibre preparation under length clamp and “fixed end” conditions. 10 and 11 intensity changes and stiffness hav...

Mechanical characteristics of skinned and intact muscle fibres from the giant barnacle,Balanus nubilus

Intact muscle fibres fromBalanus nubilus develop tensions of up to 600 kN sd m⁻² during electrical stimulation. The rise of tension occurs with a half-time (177 ms at 12° C) about fivefold longer than that of tet...

ATPase activity in rapidly activated skinned muscle fibres

The ATPase activity of single mechanically skinned fibres from semitendinosus muscle ofRana esculenta was measured. The method was based on the fluorimetrically detected consumption of NADH inside the fibre. NADH...

Cross bridge slippage in skinned frog muscle fibres

Mechanically skinned single fibres of the semitendinosus muscles of Rana esculenta were investigated at ca. 4‡ C. The fibres were activated by a Ca²⁺ jump technique, which allowed the development of a steady isom...

Ethanol-Induced Alteration in Membrane Phospholipid Composition: Possible Relationship to Development of Cellular Tolerance to Ethanol

There is now considerable evidence that unicellular organisms adapt to environmental or pharmacological agents which alter membrane fluidity by incorporating different fatty acids into the phospholipids of the...

Rate of isometric tension development in relation to calcium binding of skinned muscle fibres

Isolated muscle fibres from the sartorius or semitendinosus muscles of frogs were mechanically skinned and kept in a relaxed state in a medium containing Mg-ATP and EGTA. When subjected to a rapid increase in ...

Activation of the contractile system of insect fibrillar muscle at very low concentrations of Mg²⁺ and Ca²⁺

The mechanical properties of single fibres and fibre bundles of glycerinated dorsal longitudinal muscle from lethocerus maximus were investigated in ATP-salt solutions containing only trace concentrations of f...
