Bioprinting High‐Cell‐Density Cardiac Tissue Constructs With Sustained Contractile Function

Advanced Healthcare Materials, EarlyView.
Contractile cardiomyocytes in 3D culture provide insights into the behavior of the heart. Combining a 3D bioprinting approach with a multi‐electrode array allows the development of the 3D culture to be monitored over time, and matured cultures allow the effect of drugs on cardiac function to be modelled, replicating effects seen in clinical application.

Macrophage Membrane‐Camouflaged Nanozyme Microneedles Restore Immunovascular Homeostasis Through SPP1‐ApoE Signaling in Diabetic Wounds

Advanced Healthcare Materials, EarlyView.
Macrophage membrane‐coated Cu/Zn‐MOF nanozyme microneedles (MNs) reprogram the diabetic wound microenvironment through localized, minimally invasive delivery. By suppressing M1‐like macrophage activation while promoting extracellular matrix deposition and angiogenesis, this biomimetic platform accelerates diabetic wound repair.

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Research on pre-synchronization control strategy of the micro-grid with multi-VSG

Global Energy Interconnection, 2018
Seamless switching is an important guarantee for the inverter to work continuously without stopping when grid-connected power generation system is the transient process from grid-connected to isolated island and from isolated island reclosing. Based on the principle of pre-synchronous operation of traditional synchronous generators, this paper analyzes

Tomographic Printing in a Chip: A Versatile Platform for Biomimetic 3D Organ‐on‐Chip

Advanced Healthcare Materials, EarlyView.
A novel light‐based bioprinting approach, TVAM‐in‐a‐chip, enables rapid, contactless fabrication of biomimetic 3D organ‐on‐chip devices directly within preassembled microfluidic platforms. This strategy supports diverse materials, including cell‐laden resins, and eliminates post‐assembly steps.

Impairment of value-based decision-making in morphine-dependent rats is partly related to neural connectivity between the anterior cingulate cortex and basolateral amygdala

EXCLI Journal : Experimental and Clinical Sciences
Previous studies have established that the amygdala specifically the basolateral amygdala (BLA), has a fundamental role in decision-making. The present study aimed to investigate functional and neural synchronization between the BLA and anterior ...

Pre-synchronization Control Strategy for Grid Connection of GFM Converter Based on LADRC

Science and Technology for Energy Transition
The grid-forming (GFM) converter simulates the rotor characteristics of a synchronous motor through the application of the virtual synchronous generator control (VSG), providing crucial inertia and damping support for the grid connection of distributed generation (DG). However, in the island mode, when the DG is closed and connected to the grid, due to
