Variation of cardiac cycle during prolonged cycling exercise.
The Annals of physiological anthropology, 1989 The purpose of this study was to elucidate the changes in heart rate (HR), systolic and diastolic time intervals accompanying prolonged cycling exercise. Seven healthy male students (N group) and seven male collegiate long distance runners (LDR group) underwent 60-min bicycle ergometer exercise loaded at 30% and 50% HRmax.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Actuation of Cell Layers in Three Dimensions
Advanced Materials, EarlyView.ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the
