Increased ionic strength decreases maximal calcium-activated force (Fmax) of skinned muscle fibers via mechanisms that are incompletely understood. In detergent-skinned fibers from either rabbit (psoas) or lobster (leg or abdomen), Fmax in KCl-containing solutions was less than in potassium methanesulfonate (KMeSO3), which we showed previously was the least deleterious salt for adjusting ionic strength. In either salt, lobster fibers were considerably less sensitive to elevated ionic strength… Expand
Ion-specific protein destabilization of the contractile proteins of cardiac muscle fibers
It is found that a protein stabilizer (trimethylamine N-oxide, TMAO) completely abolished the ion-specific effects on Fmax, indicating that certain osmolytes can alter Fmax if the contractile proteins are initially destabilized. Expand
Influence of ionic strength on the time course of force development and phosphate release by dogfish muscle fibres
Only the rate constants for reactions of ATP, ADP and Pi with the contractile proteins varied with IS, thus suggesting that the actin–myosin interactions are largely non‐ionic. Expand

The present study suggests that the actomyosin interaction is generally nonionic in nature, but there are at least two ionic processes, one at the beginning and the other close to the end of the actin-myOSin interaction. Expand
Intracellular sodium homeostasis in relation to the effective free-energy change of ATP hydrolysis: studies of crayfish muscle fibers
Abstract We investigated the impact of reductions in the effective free-energy change of ATP hydrolysis (dG/dATP) on intracellular sodium homeostasis in bundles of fibers from the abdominal extensorExpand
Human skeletal muscle fibres: molecular and functional diversity.
The present review will describe the mechanisms through which molecular diversity is generated and how fibre types can be identified on the basis of structural and functional characteristics and discuss the advantage that fibre diversity can offer in optimizing muscle contractile performance.

Functional significance of cell volume regulatory mechanisms.
Cell volume may be considered a second message in the transmission of hormonal signals, and alterations of cell volume and volume regulatory mechanisms participate in a wide variety of cellular functions including epithelial transport, metabolism, excitation, hormone release, migration, cell proliferation, and cell death.

Ion-specific and general ionic effects on contraction of skinned fast- twitch skeletal muscle from the rabbit
The data indicate that increased ionic strength per sc decreases Fmax, probably by destabilizing the cross-bridge structure in addition to increasing electrostatic shielding of actomyosin interactions. Expand
Tension in Skinned Frog Muscle Fibers in Solutions of Varying Ionic Strength and Neutral Salt Composition
The maximal calcium-activated isometric tension produced by a skinned frog single muscle fiber falls off as the ionic strength of the solution bathing this fiber is elevated declining to zero nearExpand
Ionic Strength and the Contraction Kinetics of Skinned Muscle Fibers
The results suggest that in fibers activated at low ionic strength some of the cross bridges that are formed are abnormal in the sense that they retard shortening and persist in relaxing solution. Expand
The Myofilament Lattice: Studies on Isolated Fibers
It is demonstrated that the ionic strength affects the tension-generating capacity of the muscle as it affects the chemo-mechanical transform of excitation-contraction coupling and it is further demonstrated that interfilament spacing changes encountered during shortening and with variation in the osmotic strength have no effect upon the tensions of muscle. Expand
The effects of osmoregulatory solutes on tension generation in skinned fibres isolated from dogfish myotomal muscle have been investigated and it is found that TMAO acts as a general protein stabilizer and can offset the effects of urea on enzyme Km and maximal velocity in vitro. Expand
Evidence for cross-bridge attachment in relaxed muscle at low ionic strength.
Both in vitro binding and the effect of overlap on rapid stiffness measurements in fibers suggest that cross-bridges are attached to actin in relaxed muscle at low ionic strength. Expand
Contraction transients of skinned muscle fibers: effects of calcium and ionic strength
The isotonic velocity transients following step changes in load were studied in solutions in which calcium concentration and ionic strength were varied and showed that calcium has no effect on either the null time or the amplitude of the transients. Expand
Swelling of skinned muscle fibers of the frog. Experimental observations.
Frog skeletal muscle fibers swell upon transfer to aqueous relaxing medium, consistent with the idea that swelling arises from the negatively charged nature of the myofilaments, from either mutual filamentary repulsion or a Donnan-osmotic mechanism. Expand
Influence of temperature upon contractile activation and isometric force production in mechanically skinned muscle fibers of the frog
The pCa required for 50% maximal force (pCa50) was inversely proportional to absolute temperature, and the shift was consistent with a Gibbs free energy change of binding (delta G) of about -7.8 kcal/mol. Expand
