Advanced Science, EarlyView.A reconfigurable microneedle electrode array integrated system is developed for minimally invasive and transdermal monitoring of subcutaneous electromyography, reactive oxygen species, and pH values. By assembling discrete thumbtack‐shaped microneedles into an array, the system enables multi‐parameter detection with single‐microneedle resolution.

Applying the Method of Critical Fluctuations on Human Electrocardiograms [PDF]
arXiv, 2019 In this work we apply the Method of Critical Fluctuations (MCF)on human Electrocardiogram (ECG) time-series. The method is able to reveal critical characteristics, in terms of physical behavior, in experimentally recorded signals. Using the concept of criticality as basic criterion for the characterization of the recorded ECG as that of a healthy ...

Advanced Science, EarlyView.This study investigates the role of protein arginine methyltransferase 1 (PRMT1) in endothelial cells (ECs) in chronic obstructive pulmonary disease (COPD). Mice with endothelial‐specific PRMT1 deletion develop pulmonary hemorrhage, inflammation, and apoptosis, driven by excessive nuclear factor kappa B activation.
