PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...
