Bone Organoids Across the Development‐to‐Remodeling Continuum: From Tissue Formation to Functional Competence and Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Mineralization alone does not establish a mature bone organoid. This Review integrates biological foundations, materials design, adaptive remodeling, and translational validation through the development‐to‐remodeling continuum (DRC). By separating biological functions from the evidence supporting them, the framework exposes critical gaps in current ...

Bioprinted Stiffness‑Tunable Pancreatic Microniches to Decode Early Tumor Initiation Mechanisms

open access: yesAdvanced Healthcare Materials, EarlyView.
Stiffness‐tunable GelMA microniches generated by microvalve bioprinting preserve wild‐type acinar identity while revealing a nonlinear, Kras‐dependent response to matrix mechanics. Intermediate stiffness promotes acinar‐to‐ductal metaplasia and proliferation, defining a permissive mechanical window.

Artemisinin‐Loaded Core‐Shell Microspheres Modulate Histone Lactylation to Remodel the Microenvironment for Cartilage Protection in Rheumatoid Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
ART@PLGA@GH‐A microspheres are developed via microfluidic technology for intra‐articular delivery of artemisinin. The system remodels rheumatoid arthritis microenvironments by regulating metabolic and inflammatory disorders, reducing lactate‐driven histone lactylation and cellular senescence, while restoring cartilage homeostasis and protecting joint ...

Observations on Linear Anisotropic Viscoelasticity

open access: yes, 1968
The theory of anisotropic viscoelasticity is based upon the Onsager reciprocity relations. Experimental evidence presented here verifies this concept of matrix symmetry for time-dependent phenomena.

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Effect of Visco-Elasticity of an Orthotropic Arterial Wall on Pulse-Wave Propagation

open access: yesМеханика машин, механизмов и материалов, 2008
The problem of harmonic pressure wave propagation through a viscous fluid contained in a thin viscoelastic orthotropic tube is considered. To take into account viscoelasticity of the tube the linear viscoelasticity model is used.

Intravascular Photoacoustic Viscoelasticity Imaging

open access: yesPhotonics
Plaque rupture drives acute cardiovascular events and originates from a mechanical imbalance between fibrous cap integrity and lipid core loading. This process reflects the coupled elastic and viscous behavior of plaque components, and viscoelasticity ...
