Liquid Gallium Nanozyme Coatings Enable Sustained Nitric Oxide Generation With Antioxidant and Anti‐Inflammatory Functions

Advanced Science, EarlyView.
Liquid gallium (Ga) acts as a catalytic center for nitric oxide (NO) generation within a tannic acid–zirconium metal–phenolic network coating. Stabilized Ga nanoparticles catalyze S‐nitrosothiol decomposition through surface electron transfer, enabling controlled NO production, enhancing endothelial biocompatibility, and providing antioxidant and anti ...

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

Advanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

Adaptive Cellular Responsiveness to Electrical Stimulation at the Skin‐Electrode Interface

Advanced Science, EarlyView.
This study presents an adaptive bioelectronic response in which sustained electrical stimulation (ES) upregulates voltage‐gated calcium channels (VGCCs) and enhances cellular sensitivity to subsequent ES at the skin‐device interface. VGCC‐associated adaptive sensitization promotes regenerative wound‐healing responses in vivo, including accelerated ...

Real-Time Prediction of the Dynamic Spatial Configuration of Umbilical Cables Based on Monitoring Data During Deep-Sea In-Situ Mining

Journal of Marine Science and Engineering
Prediction of the spatial configuration of the umbilical cable during deep-sea mining in-situ tests is of great significance because dynamic change may cause the umbilical cable to touch the ground or overturn the mining vehicle.

TIPIN Couples Epigenetic Rewiring to EGFR Stabilization and Lenvatinib Resistance in Liver Cancer

Advanced Science, EarlyView.
DNA hypomethylation elevates TIPIN expression in liver cancer. TIPIN competes with E3 ligase c‐Cbl for the EGFR intracellular domain, inhibiting EGFR ubiquitination and lysosomal degradation to sustain oncogenic EGFR‐ ERK signaling. High TIPIN confers lenvatinib resistance, while TIPIN depletion restores drug sensitivity in liver cancer. ABSTRACT Aims:

Isogeometric contact analysis in subsea umbilical and power cables

Marine Structures
Subsea umbilical and power cables contain a large number of contact interfaces between different geometries and materials. These complex interactions rise significant challenges for accurately considering contact surface properties by using traditional analytical solutions or finite element methods.
