Lipofuscin: The Missing Link in the Worsening of Obstructive Sleep Apnea

open access: yesThe Laryngoscope, EarlyView.
Lipofuscin, also known as the age pigment, is a permanent autofluorescent intracellular deposit that accumulates with aging or oxidative stress, thereby interfering with cellular function. This study revealed significantly larger deposits of lipofuscin in the lateral pharyngeal wall muscles of patients with severe obstructive sleep apnea (OSA) compared

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

open access: yesMacromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.
