Consider the following text:

(CNN) Researchers at Yale University say they have been able to restore blood circulation and other cellular functions in pigs a full hour after the animals' deaths, suggesting that cells don't die as quickly as scientists had assumed.

With more research, the cutting-edge technique could someday potentially help preserve human organs for longer, allowing more people to receive transplants.

The researchers used a system they developed called OrganEx, which enables oxygen to be recirculated throughout a dead pig's body, preserving cells and some organs after a cardiac arrest.
