    "body_text": "The Terasaki Institute and Mayo Clinic collaborators report a dual-compartment biosensing platform for donor livers undergoing normothermic machine perfusion. The system continuously monitors pH, glucose, and lactate in the circulating preservation fluid and in bile, providing a time-resolved view that occasional samples can miss. The Nature Communications study used human tissue samples and describes clinical deployment of the monitoring platform. Whether those signals improve transplant selection or outcomes requires prospective validation beyond measuring them reliably.",
