In Vitro Calcification Evaluation of Polycarbonate Urethane—Impact of Production Processes
Artificial Organs, EarlyView.The study shows that hot pressing induces chemical changes in PCU, promoting calcification, while solution‐cast patches remain unaffected. ABSTRACT Background Heart valve diseases remain a leading cause of death in industrialized nations. Polycarbonate urethane (PCU) is a promising material for heart valve prostheses due to its biocompatibility and low

Results of GC–MS Analyses of 40 Extracts of Diabetes Devices
Contact Dermatitis, EarlyView.Forty acetone extracts of 27 diabetes devices were investigated by gas chromatography–mass spectrometry. Two hundred eighty four individual chemicals were identified. All 40 extracts contained one or more chemicals that were previously identified as allergens in diabetes devices causing allergic Contact Dermatitis.

A Triple-Catalytic, Fully Biogenic Synthesis of Cyclic Carbonates. [PDF]
ChemSusChemA three‐step synthesis of cyclic carbonates from biogenic resources (fatty acids, O2, CO2) is reported. The process operates via a visible light‐mediated hydrocarbon oxidation, with an overall 100% atom‐economy, in the presence of easily accessible catalysts (porphyrin, VO(acac)2, pyridine) but without intermediate work‐up procedures.

Do plantar calcaneal spurs make the plantar aponeurosis enthesis stronger? A biomechanical analysis
Journal of Anatomy, EarlyView.Novel testing set up for determining enthesial avulsion parameters. Donor calcanei were dissected to isolate the central band of the plantar fascia, and mounted in a custom 3D‐printed rig (Fig A, B, C) for uniaxial tensile testing of the plantar fascia enthesis (Fig D). This study demonstrated no significant differences in the avulsion parameters, Fmax

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.
