Effects of ß-adrenoceptor stimulation on cardiac function.
, 2022 Cardiac parameters were assessed after ß-adrenoceptor stimulation by building non-CCRCs to isoproterenol (10−9 to 10−6 M). The (A) LVDevP (left ventricular developed pressure) and (B) perfusion pressure, reflecting cardiac inotropy and coronary ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Synchronization‐Dissipation in the Cardiorespiratory System
Advanced Science, EarlyView.By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.
