From: Optimizing DCD donor liver function with resveratrol during machine perfusion
Experimental design and perfusion system. (a) Four rat liver groups underwent 30-min warm ischemia (DCD), then preservation: SCS (4 °C UW solution), SNMP (25 °C), or SNMP + RES (25 °C with resveratrol). All groups received 1-h NMP reperfusion (38 °C diluted donor blood). Six livers/group, plus naïve controls (ischemia + direct reperfusion). Schematic shows timeline and sampling points. (b) Perfusion circuit components: roller pump, oxygenator, reservoir, bubble trap, heating coil, and temperature monitor. Open-circuit design with unrestricted outflow (figure designed with biorender.com). (c) Portal vein pO₂ and pCO₂ levels during 2-h perfusion (SNMP vs. SNMP + RES groups).
