Phosphate rebinding induces force reversal via slow backward cycling of cross-bridges.

Objective: Previous studies on muscle fibers, myofibrils, and myosin revealed that the release of inorganic phosphate (P) and the force-generating step(s) are reversible, with cross-bridges also cycling backward through these steps by reversing force-generating steps and rebinding P. The aim was to explore the significance of force redevelopment kinetics (rate constant ) in cardiac myofibrils for the coupling between the P binding induced force reversal and the rate-limiting transition for backward cycling of cross-bridges from force-generating to non-force-generating states.

Methods: and force generation of cardiac myofibrils from guinea pigs were investigated at 0.

Cross-education: motor unit adaptations mediate the strength increase in non-trained muscles following 8 weeks of unilateral resistance training.

Introduction: Early increases in muscle strength following unilateral resistance training are typically accompanied by strength gains in the contralateral untrained muscles, a phenomenon known as cross-education. However, the specific motor unit adaptations responsible for this gain transfer remain poorly understood. To address this gap, we recorded myoelectrical activity from the biceps brachii using high-density electromyography.

Touch-driven advantages in reaction time but not in performance in a cross-sensory comparison of reinforcement learning.

Coupling of Li-Fe: Li Isotope Fractionation during Sorption onto Fe-Oxides.

Chemical weathering processes play a key role in regulating the global climate over geological time scales. Lithium (Li) isotope compositions have proven to be a robust proxy for tracing weathering processes that produce secondary minerals, such as clays and oxides, with a focus often placed on Li adsorption to, or incorporation into, clay minerals. In addition, the interaction between Li and Fe-oxides has long been assumed and discussed based on field observations, but experimental constraints on this process are lacking.
