Advanced Functional Materials, EarlyView.We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

The role of α7 nicotinic acetylcholine receptor in modulation of heart rate dynamics in endotoxemic rats. [PDF]
PLoS ONE, 2013 Previous reports have indicated that artificial stimulation of the vagus nerve reduces systemic inflammation in experimental models of sepsis. This phenomenon is a part of a broader cholinergic anti-inflammatory pathway which activates the vagus nerve to

Unravelling the effects of mechanical physiological conditioning on cardiac adipose tissue-derived progenitor cells in vitro and in silico [PDF]
, 2018 Mechanical conditioning is incompletely characterized for stimulating therapeutic cells within the physiological range. We sought to unravel the mechanism of action underlying mechanical conditioning of adipose tissue-derived progenitor cells (ATDPCs ...

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 ...

Mechanical Communication Acts as a Noise Filter
iScience, 2019 Summary: Cells can communicate mechanically by responding to mechanical deformations generated by their neighbors. Here, we describe a new role for mechanical communication by demonstrating that mechanical coupling between cells acts as a signaling cue ...

Alternative endocardial sites for artificial cardiac stimulation.
Arquivos brasileiros de cardiologia, 2011 The conventional right ventricular stimulation can be associated with deleterious effects on cardiac function. The need for a more physiological artificial cardiac stimulation is undoubtedly one of the most important points in the area of cardiac electrotherapy. The programming algorithms for the maintenance of adequate atrioventricular conduction, the
