3D Multicellular Scaffold Based Model for Advancing Bone Disorder Research

open access: yesAdvanced Functional Materials, EarlyView.
A scalable 3D multicellular in vitro bone model engineered by integrating osteoblasts, osteoclasts, and endothelial cells on biodegradable scaffolds. The system recapitulates key features of human bone remodeling and disease pathology. As a proof of concept, the model mimics osteogenesis imperfecta, demonstrating its potential as a physiologically ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Evening the Playing Field: Tailoring the Allocation of the Burden of Proof at IDEA Due Process Hearings to Balance Chldren\u27s Rights and Schools\u27 Needs [PDF]

open access: yes, 2005
The Individuals with Disabilities in Education Act (the IDEA ) is a broad federal mandate intended to make a free appropriate public education available to all disabled students. More importantly, however, the IDEA encourages schools to enable parents

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts
