Second‐generation prokineticin PKR1 receptor agonists: Advancing cardioprotection against chemotherapy‐induced toxicity

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 12, Page 3377-3394, June 2026.
IS39, a novel non‐peptide PKR1 agonist, confers cardioprotection against doxorubicin‐induced toxicity. IS39 activates PKR1‐mediated pro‐survival signalling in cardiomyocytes, reducing reactive oxygen species (ROS), DNA damage and fibrosis markers. In vivo, IS39 preserves cardiac geometry and function in mice exposed to chronic doxorubicin challenge ...

Existence of Myopic‐Farsighted Stable Sets in Matching Markets

open access: yesEconometrica, Volume 94, Issue 3, Page 811-841, May 2026.
In the context of one‐to‐one matching markets, we study myopic‐farsighted stable sets, which are internally and externally stable when myopic agents consider immediate payoffs from their deviations, while farsighted agents anticipate counter‐deviations and consider final payoffs. We constructively prove the existence of a (rational expectations) myopic‐
