Yes, what I was saying was for the brain though I do not think the cord 
is very resistant to true Ischemia (Clamping the cord involves some 
collateral flow .
Regarding Kidneys and Liver , they cannot be better than the time for 
transplantation. Unfortunately we do not flush perfuse these organs and 
isolate them so the times will be less. I have used whole body 
retroperfusion just to keep these organs cool and I do not think they 
really provide nutritive flow due to valves in the lower body venous 
circuit.
Incidentally I missed out the Clinton bit can somebody explain it to me ?
