Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Defensin‐DNA Supramolecular Complexes as a New pH‐Sensing Nanomaterial

Aggregate, Volume 7, Issue 6, June 2026.
Crocodylus porosus β‐defensin 13 (CpoBD13), a host defence peptide from the saltwater crocodile, is discovered to interact with single‐ and double‐stranded DNA to form supramolecular assemblies, termed defensin‐induced spherical complexes (DISCs).

Disulphide structure of a sunflower seed albumin: conserved and variant disulphide bonds in the cereal prolamin superfamily

, 1996
Disulphide mapping of a methionine-rich 2S albumin from sunflower seeds showed four intra-chain disulphide bonds which are homologous with those in a related heterodimeric albumin from lupin seeds (conglutin δ).

Retention of the Full Visual Opsin Repertoire in Some Australian Cryptozoic Lizards

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study investigates the link between visual evolution and fossorial habits in the endemic Australian skink genus Lerista. We provide evidence for positive site‐specific selection in all 4 cone opsins, as well as relaxed selection specific to LWS. We also provide evidence of selection linked to limb reduction, an indicator of fossorial adaptation ...

The disulphide bonds of an Asian influenza virus neuraminidase

, 1983
The arrangement of the disulphide bonds in the pronase-released neuraminidase heads of the Asian influenza virus A/Tokyo/3/67 have been examined by cyanogen bromide fragmentation, enzymic digestion and diagonal peptide mapping.

Mesna in Otologic Surgery: Efficacy and Safety—A Scoping Review

The Laryngoscope, Volume 136, Issue 6, Page 2449-2460, June 2026.
PRISMA flow diagram indicating the process of systematic inclusion and exclusion of articles. ABSTRACT Objective Mesna (Sodium 2‐mercaptoethanesulfonate) is widely used as a mucolytic agent and uroprotective agent. Recently, its disulfide bond‐breaking property has been applied in otologic surgery to facilitate safer dissection of cholesteatoma and ...
