Dual‐Network Protein Hydrogels Promote Rapid Hemostasis and Immune‐Regulated Scarless Tissue Regeneration

Advanced Science, EarlyView.
A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.

A Non-Oxidative Approach toward Chemically and Electrochemically Functionalizing Si(111) [PDF]

, 2006
A general method for the non-oxidative functionalization of single-crystal silicon(111) surfaces is described. The silicon surface is fully acetylenylated using two-step chlorination/alkylation chemistry.

Multi‐Property Machine Learning Models to Accelerate the Transition Toward Bio‐Based Emulsion Polymers

Advanced Intelligent Discovery, EarlyView.
A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...

Exogenous ochronosis: case report and literature review Ocronose exógena: relato de caso e revisão de literatura

Anais Brasileiros de Dermatologia, 2012
Exogenous ochronosis is a rare, cosmetically disfiguring condition, resulting from the longterm use of topical hydroquinone in treatment of melasma. It manifests as gray-brown or blue-black macules in hydroquinone-exposed regions.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

On-line Electrochemical Tagging of Free Cysteines in Peptides during Nanospray Ionisation Mass Spectrometry: An Overview

CHIMIA, 2004
A recently developed nanospray interface for mass spectrometry (MS) was used to electro-generate benzoquinone from hydroquinone. When spraying biomolecules containing free cysteine residues in the presence of hydroquinone, the thiol cysteine ...
