Un récent article du New York Times partage des résultats d’un article publié dans Nature Medecine où les scientifiques ont ressuscité des poumons endommagés à l’intérieur de 24 heures en utilisant la circulation porcine et des respirateurs.

They were damaged, swollen and soggy with fluid. Like 80 percent of lungs offered for transplant, these were just too far gone for the operation.
But researchers at Columbia and Vanderbilt saw an opportunity. They had been working for eight years on a system to restore damaged lungs.
