Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

Journal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

Diagnostic Accuracy of APTw and NOEw MRI Metrics for IDH Mutation and 1p/19q Codeletion Prediction in Gliomas

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
We evaluated how confounding effects from fluid, macromolecules and T1 relaxation impact the performance of APTw and NOEw metrics for noninvasive glioma classification at 3 T. Corrected APTw metrics showed the highest discriminations of IDH‐mutant from wild‐type gliomas (AUC = 0.94–0.96), whereas NOEw metrics did not differ between groups.

Conformational determinants of glucagon stability and aggregation kinetics in aqueous and commercial formulations

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Glucagon is a well‐established therapeutic peptide, widely used to treat hypoglycemia. Like many peptide drugs, it offers advantages such as specificity, biocompatibility, and high affinity for receptor targets, but suffers from limited physical and chemical stability.

Sequence‐encoded determinants drive distinct early aggregation pathways and different structural outcomes in PNT1 fibrils across Henipavirus members

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Protein aggregation is increasingly recognized as a biologically relevant process in viral proteins, yet the molecular determinants governing such phenomena remain poorly understood. Intrinsically disordered proteins (IDPs) are ubiquitous in viral proteomes, where conformational plasticity not only enables functional diversity but also permits

From Fragments to Function: Novel Hydrazone Derivatives as Monoamine Oxidase Inhibitors

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Twelve N‐acylhydrazone derivatives (5a–f, 6a–f) were synthesized and characterized. Compounds displayed potent submicromolar inhibition against both MAO‐A and MAO‐B. Compound 6e exhibited the strongest activity (IC50 = 0.073 μM for MAO‐A; 0.064 μM for MAO‐B). Kinetic and docking analyses confirmed reversible, competitive inhibition via FAD interaction.
