Modified ‘dumbbell' technique: a simple and intuitive method to position balloon-expandable stent valves [PDF]

, 2017
Intraoperative cardiac imaging plays a key role during transcatheter aortic valve replacement. In recent years, new techniques and new tools for improved image quality and virtual navigation have been proposed, in order to simplify and standardize stent ...

Orbital Coupling and Spin Textures of Fe/Pd Thin Films Grown on Si Substrate with High Magnetic Fields

Advanced Science, EarlyView.
High magnetic fields (HMFs) regulate orbital coupling and spin polarization in Fe/Pd thin films, promoting crystallization and ordered spin textures. HMF‐assisted growth transitions Fe from amorphous to dense 2D structures, enhancing saturation magnetization and domain uniformity. This strategy advances the design of high‐performance spintronic devices

Dipyridamole Acts as Clinical Ferroptosis Inhibitor to Prevent from Tissue Injury

Advanced Science, EarlyView.
Dipyridamole acts as a clinically used compound to suppress ferroptosis. Dipyridamole down‐regulates the expression of RNF126, which is an E3 ligase to ubiquitinate SLC7A11 for proteasome degradation. The deficiency of SLC7A11 largely abolishes the protective role of dipyridamole both in vitro and in vivo.

Injectable and Sprayable Thermoresponsive Hydrogel with Fouling‐Resistance as an Effective Barrier to Prevent Postoperative Cardiac Adhesions

Advanced Science, EarlyView.
Postoperative cardiac adhesions lead to numerous difficulties in reoperation procedures. Here, a thermo‐responsive in situ formed hydrogel is shown to can reliably cover the wounds after a convenient spraying or injection and significantly reduce adhesion formation in primary and recurrent cardiac injury adhesion models.

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

Advanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.
