An Agonist/Antagonist Photo‐Switchable Vitamin D Mimetic Enables Bidirectional Optical Control of VDR

open access: yesAngewandte Chemie International Edition, EarlyView.
Vitamin D exhibits complex and cell‐specific biological effects in multiple tissues via activation of the ligand‐sensing transcription factor vitamin D receptor (VDR). The photo‐switchable vitamin D mimetic 10 transitions between VDR antagonist (E) and agonist (Z) activity upon illumination and offers unprecedented bidirectional optical control over ...

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

open access: yesJournal of Applied Polymer Science, EarlyView.
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.

Hyperostosis frontalis interna: Observed patterns, prevalence, and dementia associations in older adults

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperostosis frontalis interna (HFI) is a frequently underrecognized condition characterized by overgrowth of the frontal endocranium, most commonly observed in post‐menopausal women. Although its etiology remains unclear, hormonal influences and a possible relationship with neurocognitive changes have been proposed.
