Invention of resurrection from the dead technology
Hope for human immortality?
If people could come back to life after death, what would the world be like?
There might be no more death, and humans would live forever.
"Plants that "come back from the dead
However, resurrection from the dead only happens in mythological stories, and in real life, people often do not come back from the dead.
However, a group of scientists in the United States has really achieved "back from the dead", so that the organs of the dead for a period of time rejuvenated.
This technology continues to develop, it will really bring people back to life in situ.
However, is it really good to revive a dead person?
Can a person come back to life after death?
"Resurrected" pig brains
The medical definition of brain death is true death, because after the death of the brain, all human activities can not be carried out, including breathing.
Without the ability to breathe, the cells in the body cannot breathe aerobically and synthesize energy.
Normally, the body is deprived of oxygen for more than 15 minutes, and all the cells of the organism die irreversibly.
So, Nenad Sestan, a professor of medicine from Yale University, managed to "revive" the brain of a pig after it died by filling it with extra fluid.
The brain decides whether we live or die
The experiment was conducted in 2019, when the pig had been dead for four hours, the body had long been cold, according to the normal process, dragged to the slaughterhouse is not fresh.
It was such a cold pig, part of its body was indeed revived by Célestin.
Cestan will be a special liquid into the pig's brain, after the pig's brain cells began to rejuvenate.
In no time, the brain returned to its fresh appearance, as if it had just been taken out of the pig's head.
Imagine using this liquid to "revive" the pig's vital organs after its death.
Professor Nenad Sestan
If this fluid is used in a human being, then the human being can also be revived.
Three years after the pig brain "reanimation" experiment, Prof. Sestan published an article in the journal "Nature".
In it, he talks about the "resurrection" of organs and the future prospects of this technology.
So, what is the liquid that Professor Sestan injects into pig organs?
Can this technology really bring back the dead?
Experimental pigs
The mysterious resurrection fluid
According to Professor Sestan's paper, the technology he used to revive the pig's brain is called OrganEx perfusion fluid, the main component of which is human hemoglobin and blood, mixed in a 1:1 ratio.
Because the body's cells die mainly from lack of oxygen after brain death, human hemoglobin is able to carry more oxygen, which is equivalent to supplying oxygen toward the oxygen-deprived cells inside.
However, mammalian cells are already beyond saving after 15 minutes of oxygen deprivation, so why was he able to "revive" the pig brain after using OrganEx perfusion solution?
Hemoglobin
It turns out that OrganEx perfusion fluid is only one of the OrganEx technology, in addition to the injection of this liquid, but also requires the use of simulation technology, used to restore the body's blood circulation, heart and lung function.
The real difficulty is not in the perfusion fluid, but in this system.
In layman's terms, Cestan removed the pig's brain and put it into another "live pig" body, using the external supply of oxygen to make it re-energized.
In this way, it seems less like a resurrection and more like an organ transplant, except that the transplanted object is not a physical object, but a simulated system.
Human blood circulation
Regarding OrganEx technology, only Nenad Sestan is at the forefront, and there is exceptionally little information about it that can be found.
Shupei Zhang, M.D., of Yale University, added to Setans' experiments, saying that OrganEx technology is an improvement on the technology of ECMO, which was originally how organs were kept at a minimum loss during transplantation.
The traditional ECMO technique is to simply use oxygen perfusion, which can cause reperfusion damage to the cells.
Using OrganEx technology, it was able to reduce cellular breakage and, in some organs, even achieve cell proliferation.
This technology has received support from peers, and many surgical experts say it will have a profound impact on the future of organ transplantation.
Cestan's pig brain experiment has a specific term in academia called BrainEx, however, it was this BrainEx that caused the uproar that followed.
ECMO technology in organ transplantation
The "Resurrection" Debate
Harvard University's Soo-Hyun In believes that BrainEx technology, which could make the current organ transplant system controversial, would be breaking the law if it delayed transplantation.
In Soo Hyun, who specializes in medical and ethical research, mentioned that in medicine, a person's death is judged according to brain death.
However, the definition of brain death is very vague, especially when a person suffers an accident and has severe brain damage, but is still not brain dead, it does not meet the definition of brain death.
Therefore, in organ transplantation, there are two criteria for judging.
Organ Donation
The first is brain death, and this is the most normal death in the medical sense.
The second one is circulatory death, which is after the heart has stopped beating for 2 to 5 minutes.
The reason for the definition of death is that there is a golden time for organ removal, and the quicker the removal the higher the probability of a successful transplant.
If BrainEx technology is used, then the brain stays alive and there is no longer any such thing as brain death.
If there is no brain death, then transplantation is nonsense.
If the brain does not die, the human race will not die
As for the "resurrection from the dead" that many people believe, medical experts are unanimous in saying that if this technology keeps the human brain alive or, in a way, the human being will always be alive, a kind of immortality.
But what is the point of such immortality? The equivalent of being a vegetable.
One might think that if every human organ is revived using OrganEx, will the person be revived?
In fact, as long as the brain is alive, then the other organs in the body are theoretically alive, and there is no need to resurrect other organs.
In addition, there is still a fundamental difference between the brain being alive and the whole person being alive, and there are many definitions of alive, such as living like the walking dead, living with a bang, etc.
What is a vegetable
The pig brain "reanimation" experiment caused a huge shock in the American academic community, and Nita Farahani, a specialist in law and philosophy at Duke University, published an article about the pig brain experiment.
In her article, she writes that organ transplants should be donor-based, rather than prioritizing the value of the transplant.
To put it bluntly, if the donor is not qualified to remove the organ, then we cannot force or remove it early because we are in a hurry, because that, too, is against the law.
It is a dilemma that both organ donors and organ recipients are human beings and they should have their rights as human beings.
However, it seems difficult to have it both ways when it comes to organ transplants.
Organ donors should be above the value of their organs
Resurrection and Immortality
Although there is no direct correlation between the pig brain "resurrection" experiment and human immortality, this incident has sparked a discussion about resurrection from the dead.
The known "resurrection from the dead" is a human freezing technique that uses liquid nitrogen to rapidly cool the human body at -180°C to prevent ice crystals from piercing the cellular tissue.
The body is then frozen in liquid nitrogen until it is reanimated in the future.
In fact, for the frozen individual, he or she is not dead, human cryopreservation requires freezing before brain death, which is equivalent to freezing the human state at the moment before death.
Human freezing
There is no waking technology, so at this stage of human freezing, it is a large ice coffin, or a particularly expensive kind.
The earliest frozen people were planned to wake up in 2017, but did not reach that technology, so the freezing will be extended.
Human freezing technology is time-consuming and energy-consuming, and cannot be interrupted in the middle, otherwise it is all a bubble.
If mankind suffers an energy crisis before the development of waking technology, then all these frozen people will be abandoned.
Human freezing is very energy-intensive
Another medical fantasy of immortality is the repair of the telomeres of chromosomes.
Telomeres are a marker of the limit of human lifespan, and they stop shortening when they reach a certain length, which means that cells stop dividing.
Humans can increase in value indefinitely during embryonic life because at this time telomerase is still present and will repair our shortened telomeres.
But when differentiation begins and humans have a life span, telomerase stops being synthesized and the countdown to telomere shortening begins.
If humans could repair their telomeres, then the division of human cells would never end and human life span would be extended indefinitely, eventually becoming immortal.
Naturally, there is one type of cell that can do this, and that is the cancer cell that people see and fight.
Immortal cancer cells
Yes, cancer cells are immortal. If human beings live forever, do we become the cancer cells of the earth?
