The synergic role of actomyosin architecture and biased detachment in muscle energetics: Insights in cross bridge mechanism beyond the lever‐arm swing
No full textMuscle energetics reflects the ability of myosin motors to convert chemical energy into mechanical energy. How this process takes place remains one of the most elusive questions in the field. Here, we combined experimental measurements of in vitro sliding velocity based on DNA-origami built filaments carrying myosins with different lever arm length and Monte Carlo simulations based on a model which accounts for three basic components: (i) the geometrical hindrance, (ii) the mechano‐sensing mechanism, and (iii) the biased kinetics for stretched or compressed motors. The model simulations showed that the geometrical hindrance due to acto-myosin spatial mismatching and the preferential detachment of compressed motors are synergic in generating the rapid increase in the ATP‐ase rate from isometric to moderate velocities of contraction, thus acting as an energy‐conservation strategy in muscle contraction. The velocity measurements on a DNA‐origami filament that preserves the motors’ distribution showed that geometrical hindrance and biased detachment generate a non‐zero sliding velocity even without rotation of the myosin lever‐arm, which is widely recognized as the basic event in muscle contraction. Because biased detachment is a mechanism for the rectification of thermal fluctuations, in the Brownian‐ratchet framework, we predict that it requires a non‐negligible amount of energy to preserve the second law of thermodynamics. Taken together, our theoretical and experimental results elucidate less considered components in the chemo‐mechanical energy transduction in muscle
Transmitting the Quintessence of Everyday Life to the Next Generation : Based on the Discourse of YANAGIDA Kunio
No full textRecently, people seem to lose the consciousness of transmitting to younger generations about the human virtues in ordinary life. In this note the author examines the discourses of Yanagida Kunio on the succession of culture in former time and urges to reconsider the importance of transmission of culture on daily life in our time.研究ノートdepartmental bulletin pape
Neutrinos and cosmological matter-antimatter asymmetry: A minimal seesaw with Frampton-Glashow-Yanagida ansatz
No full textIn light of the latest neutrino data, we revisit a minimal seesaw model with the Frampton-Clashow-Yanagida ansatz. Renormalization-group running effects on neutrino masses and flavor mixing parameters are discussed and found to essentially have no impact on testing such a minimal scenario in low-energy neutrino experiments. However, since renormalization-group running can modify neutrino mixing parameters at high energies, it does affect the leptogenesis mechanism, which is responsible for the observed matter antimatter asymmetry in our Universe. Furthermore, to ease the conflict between the naturalness argument and the successful leptogenesis, a special regime for resonant leptogenesis is also emphasized.National Recruitment Program for Young Professionals; CAS Center for Excellence in Particle Physics (CCEPP)SCI(E)ARTICLE163
