Question

Can someone help me rephrase this.

Within minutes of the final heartbeat, a cascade of biochemical events triggered by a lack of blood flow, oxygen, and nutrients begins to destroy a body's cells and organs. A team of
scientists has found this massive and permanent cellular failure doesn't have to happen so quickly. Using a new technology they developed -- which delivers a specially designed cell-
protective fluid to organs and tissues - the researchers restored blood circulation and other cellular functions in pigs a full hour after their deaths

Answer 1

Within minutes of the last heartbeat, the body's cells and organs start to degrade due to a series of biochemical processes brought on by a deficiency in nutrition, oxygen, and blood flow. This significant and irreversible cellular breakdown doesn't have to occur as soon, according to a team of researchers. The researchers revived blood flow and other cellular functions in dead pigs an hour later using a novel device they created that distributes a specifically tailored cell-protective fluid to organs and tissues.
