An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Time in Space: Velimir Khlebnikov and the “Philosophy of Hyperspace”

Arts
This article reconceptualizes Velimir Khlebnikov’s aesthetic temporality not as a lyrical motif but as an epistemic procedure through which poetic language tests the legibility of history.

Differential regulations of fibronectin and laminin in Smad2 activation in vascular endothelial cells in response to disturbed flow

Journal of Biomedical Science, 2018
Background Atherosclerosis occurs in arterial curvatures and branches, where the flow is disturbed with low and oscillatory shear stress (OSS). The remodeling and alterations of extracellular matrices (ECMs) and their composition is the critical step in ...

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Circulant matrices on global data analysis [PDF]

, 2017
In this thesis, we investigate the unbiasedness of the commonly used covariance and variogram estimators when the underlying process is assumed to be stationary on the circle or axially symmetric on the sphere. We represent both estimators as a quadratic

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane
