Main research topics
Summary: I am researching how nanoscale biomolecules produce robust heartbeat rhythms. I found that myocardium uses the heat of body temperature to create a contractile rhythm that combines chaotic instability and homeostatic stability (figure). And I got a mathematical model prediction that its contractile rhythm characteristics are important for rapid ventricular dilation with each dilation of the heart. It is strongly suggested that this result may lead to pre-illness diagnosis and preemptive medical care for heart disease, and I am currently conducting research with this exit orientation.
Hyperthermal sarcomeric oscillations (HSOs): I have discovered that by warming myocardial cells to about body temperature, sarcomeres inside cardiomyocytes become HSOs, which repeatedly contract and relax in a cycle close to the heartbeat. Interestingly, HSOs kept their cycle constant despite their sensitive changes in amplitude and waveform under the influence of changes in intracellular calcium concentration. Furthermore, HSOs have found that the amplitude and phase are chaotically changed in order to achieve both responsiveness and stability.
Electron microscope live imaging method (DET film method): We have developed a technology for observing the structure and “movement” of submerged samples such as wet organs as they are with a scanning electron microscope. This measurement is possible by creating and using a thin film (DET film: Deformable and Electron Transmissive Film) that can withstand the pressure difference between vacuum and atmospheric pressure and has excellent electron beam permeability and deformability. Currently, I am conducting research and development toward the realization of observation and measurement of various nanoscale dynamics.
