AB  - Calcium ions (Ca2+) tune and control numerous diverse aspects of cochlear and vestibular physiological processes. This paper is focused on the Ca2+ control of mechanotransduction in sensory hair cells in the context of polyelectrolyte properties of actin filaments within the hair–bundles of inner ear. These actin filaments appear to serve as efficient pathways for the flow of Ca2+ ions inside stereocilia. We showed how this can be utilized for tuning of force–generating myosin motors. In an established model, we unified the Ca2+ nonlinear dynamics involved in the control of myosin adaptation motors with mechanical displacements of hair–bundles. The model shows that the characteristic time scales fit reasonably well with the available experimental data for spontaneous oscillations in the inner ear. This scenario promises to fill a gap in our understanding of the role of Ca2+ ions in the regulation of processes in the auditory cells of the inner ear. © 2018 Elsevier B.V.

AB  - Cellular long-range transport involves motor proteins (MPs) (especially, kinesin and myosin) which contain a so-called relay helix. Its motion is of crucial importance to the conversion of chemical energy released in ATP hydrolysis into the coordinated mechanical movement of the entire motor protein. In this paper, we propose two combined nonlinear mechanisms for this particular functional activity and suggest the application of neutron scattering assays to experimentally determine the incoherent dynamic structure factor S(q, omega). We argue that this type of experiment is not only feasible but it could offer significant insights into the mechanism of MP function at a molecular level.

AB  - We investigate the electronic degrees of freedom in cytoskeletal microtubules in the continuum approximation. The equations of motion of the propagating local conformational state are solved in the low temperature regime. The solution, which is a kink excitation, is coupled to the motion of the mobile electron of the constituent tubulin. We calculate the influence of kink excitations on the probability of the Mossbauer emission of gamma-active nuclei. A discussion follows on this potentially useful experimental tool for the detection of nonlinear excitations in a microtubule. [S1063-651X(98)14810-9].
