Phase resetting in human stem cell derived cardiomyocytes explains complex cardiac arrhythmias.
PLoS Computational BiologyPhase resetting of cardiac oscillators underlies some complex arrhythmias. Here we use optogenetic stimulation to construct phase response curves (PRC) for spheroids of human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CM) and a ...

An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring
Advanced Science, EarlyView.This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.

Advanced Science, EarlyView.Epsilon‐near‐zero (ENZ) silicon carbide enables a selective far‐infrared emitter spectrally aligned with the human skin window around 10 µm for wavelength‐matched thermal therapy. In 25 within‐subject trials (50 hands) monitored by laser speckle contrast imaging, SiC increases blood perfusion by 30.2% versus a broadband graphite emitter while ...

Advanced Science, EarlyView.In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Management of ventricular storm with thoracic epidural anesthesia
Annals of Cardiac Anaesthesia, 2019 The incidence of recurrent ventricular arrhythmias is increasing these days. Ventricular electrical storm can be of three types as follows: monomorphic ventricular tachycardia (VT), polymorphic VT, and ventricular fibrillation.

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System
Advanced Electronic Materials, EarlyView.This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐
