Can You Come Back Hours After Death

In a new development, scientists announced on Wednesday that they have restored cell and organ function in pigs after death. Sounds incredible, right? The technology delivered a specially designed cell-protective fluid to organs and tissues, restoring blood circulation and other cellular functions in pigs a full hour after their death.Also Read – Two-headed calf with pig-like body and double tongue Born in Russia, dies a few days later

The findings, recently published in the journal Nature, may help expand the health of human organs during surgery and increase the availability of donor organs. Also Read – Meet Pigcasso – the Artistic Pig whose paintings are sold for over Rs 2 Lakhs

“All cells don’t die instantly, there’s a more protracted chain of events,” said David Andrijevic, associate research scientist at the Yale School of Medicine and co-lead author of the study. Also Read – Foods That Can Make Your Skin Look Older

“It’s a process where you can intervene, stop and restore some cellular function,” Andrijevic said.

The research builds on a previous Yale-led project that restored circulation and certain cellular functions in the brain of a dead pig with technology called BrainEx.

In the new study, the scientists applied a modified version of BrainEx called OrganEx to the whole pig.

The technology consists of a perfusion device similar to heart-lung machines — which do the work of the heart and lungs during surgery — and an experimental fluid containing compounds that can promote cellular health and suppress inflammation throughout the pig’s body.

Cardiac arrest was induced in anesthetized pigs treated with OrganEx one hour after death.

Six hours after the OrganEx treatment, the researchers found that certain key cellular functions were active in many parts of the pigs’ bodies, including the heart, liver and kidneys.

Some organ functions were also restored. For example, they found evidence of electrical activity in the heart, which retained its ability to contract.

The team was especially surprised to observe involuntary and spontaneous muscle movements in the head and neck area when they evaluated the treated animals, which remained anesthetized for the entire six-hour experiment.

These movements indicate the preservation of some motor functions, the researchers said. Additional studies are needed to understand the apparently restored motor functions in the animals, they said.

The researchers also called for a rigorous ethical review by other scientists and bioethicists. The OrganEx technology could have several potential applications in the long term, according to the researchers.

For example, it could extend the lifespan of organs in human patients and increase the availability of donor organs for transplantation. It can also help treat organs or tissue damaged by ischemia during heart attacks or strokes, she added.
