Thermal stereoisomerization of all-(E)-.BETA.-carotene: (Z)-.BETA.-carotenes and electrocyclized .BETA.-carotenes.

open access: yesJournal of Nutritional Science and Vitaminology, 1983
Thermal isomerization of synthetic all-(E)-beta-carotene yielded a multi-component mixture composed of more than sixteen (Z)-beta-carotenes and two thermo-cyclized isomers. They were separated and purified by high-performance liquid chromatography. Ten of these were characterized by spectroscopic methods as four mono-(Z)-, five di-(Z)-, and one tri-(Z)-

Targeted Inhibition of CD74+ Macrophages by Luteolin via CEBPB/P65 Signaling Ameliorates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study identifies CD74⁺ macrophages as key drivers of synovial inflammation in osteoarthritis (OA). The flavonoid luteolin is predicted to inhibit this pathway by blocking Nuclear Factor Kappa‐light‐chain‐enhancer of Activated B cells (NF‐κB) signaling. To enhance delivery, a targeted nanoplatform (MDSPL) is developed.
