Push–Pull Phenazine Fluorophores: Substituent‐Position Effects on Emission and Intermolecular Organization Modulated by Hydrogen Bonding and Molecular Symmetry

ChemistryEurope, Volume 4, Issue 6, June 2026.
Push–pull substitution activates fluorescence in the weakly emissive phenazine scaffold, producing photostable green‐to‐red emitters via a one‐step annulation. A systematic comparison of positional isomers reveals that the Etter‐rule‐directed hydrogen‐bonding patterns modulate the emission wavelength and crystal packing, while the molecular symmetry ...

Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 719-724, June 2026.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

Variation in the Oxidative State of Collared Flycatcher (Ficedula albicollis) Nestlings and Its Association With Their Plumage Coloration

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Plumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).

An edge β‐strand mutation turns ubiquitin into a pore‐forming amyloid

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Ubiquitin (Ub) is a highly conserved eukaryotic protein, generally regarded as stable and soluble under physiological conditions, playing a key role in maintaining cellular protein balance. Using complementary bioinformatic, biophysical, immunochemical, and electrophysiological approaches, we show that a single point mutation—the substitution ...

Investigating the Phytochemical Constituents, Anti‐Inflammatory, and Neuropharmacological Activities of Podocarpus neriifolius Leaves Through FT‐IR, GC–MS, Experimental Studies, Molecular Docking, and Molecular Dynamics Simulations

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Podocarpus neriifolius, a widely distributed medicinal plant in South and Southeast Asia, has traditionally been used to treat rheumatism and joint pain. This study aimed to investigate the phytochemical profile and therapeutic potential of the ethanolic leaf extract of P.
