Colorimetric Method for Monensin

open access: yesJournal of AOAC INTERNATIONAL, 1973
Abstract A colorimetric method has been developed for the analysis of monensin, an anticoccidial agent. The principle of the method is adaptable to feeds, premixes, fermentation broth, and crystalline samples. A solution of 3% vanillin in 0.5% sulfuric acid in methanol was used as the color reagent for monensin.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
