Advanced Science, EarlyView.A damage‐free iCVD fluoropolymer passivation strategy is introduced for ambipolar vertical OECTs. Vapor‐phase infiltration and thermal annealing induce nanoscale phase separation in the OMIEC channel, enhancing overall device performance. A single‐channel bipolar event‐driven spiking encoder is also demonstrated for electrocardiogram signal encoding ...

Advanced Science, EarlyView.Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...

Thickness‐Gradient Liquid Metal Connectors for Seamless Electrophysiological Sensors
Advanced Science, EarlyView.Thickness‐gradient liquid metal interfaces with elastomeric substrates enable seamless integration between ultrathin skin‐conformal electrodes and external interconnects. The mechanically compliant connector reduces interfacial mismatch and supports stable ECG/EMG monitoring under bending and motion.

BJS (British Journal of Surgery), EarlyView., 2020 All patients operated for oesophageal cancer in Sweden from 2013 to April 2018 were identified, and 246 patients were recruited to this population‐based nationwide Swedish study. The results show that longitudinal health‐related quality of life after minimally invasive oesophagectomy was similar to that of the open surgical approach.

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ
Advanced Science, EarlyView.UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...
