NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

Advanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Selecting forwarding neighbors in wireless Ad Hoc networks [PDF]

Proceedings of the 5th international workshop on Discrete algorithms and methods for mobile computing and communications, 2001
Broadcasting is a fundamental operation which is frequent in wireless ad hoc networks. A simple broadcasting mechanism, known as flooding, is to let every node retransmit the message to all its 1-hop neighbors when receiving the first copy of the message. Despite its simplicity, flooding is very inefficient and can result in high redundancy, contention,

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Analysis of load balance performance of multipath in wireless ad hoc networks

Tongxin xuebao, 2005
A novel analysis model for computing the load of wireless ad hoc network that uses multipath routing was proposed. This model took the number of paths, the way of route selecting and the density of the network nodes into account and could analyse or ...

Disrupting Lipid Raft Microdomains to Block Polyploid Giant Cancer Cell Budding and Enhance Radiotherapy Response

Advanced Science, EarlyView.
Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

Advanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical
