Perhaps the high offer of deadly weapons was what prompted Shi Jinping and Vladimir Putin to think about deaths in the military procession this week in Beijing.
This joking was more than a serious discussion, but with each of 72 years old, the Chinese president and his Russian counterpart may feel more cold on the shoulder than Kim Jong Un, the 41 -year -old North Korean leader who wandered beside them.
Speaking through a translator, Xi Putin told that 70 is a young man today, which prompted Putin to claim that human organs can now be planted again and again, which may allow people to “avoid aging indefinitely.” “This century,” Shi replied, “It may be possible to live up to 150.”
It was a modern conversation, but he had a progress in the transplantation of organs that reached the stage in which the procedures could extend the life of healthy human beings as well as saving those who suffer from a final disease?
For the appointed patients, the transplant is clear. “When you suffer from kidney, liver, or heart disease in the final stage, the transplant adds years of age in general,” says Reza Motallebzadeh, a UCL. “It is completely savior.”
A long list of organs and tissues can now be grown, including the heart, lungs, kidneys, pancreas, liver, small intestine, skin, bones, heart valves and cornea. More members are added. Earlier this year, she became the first woman in the UK giving birth after receiving a womb that her sister donated.
Throughout the world, the demand for organ transplants exceeds display. In Britain, the waiting operations list for life -saving organ transplants was not higher. With limited supplies, what members are in those who benefit more than others – are usually young and metabolic.
But what if we have abundant supplies of members? Is it logical to offer them to the elderly to keep them well? Motallebzadeh is skeptical. He says: “The organ transplant is a huge process and it must be strong enough physiologically to overcome this,” he says.
This is not the only consideration, says Mothlbadah. “The three main causes of death in the recipient of the transplant are cancer, infection, and cardiovascular disease. Many anti -rejection treatments have side effects that lead to this.”
In short, the presence of multiple tours of surgery and continuous doses of strong anti -rejection medications, which increase the risk of cancer, cardiovascular disease and deadly infections, instead of extending it.
The main efforts are in a swing to solve the problem of organ deficiency. One path involves the use of organs of pigs. This procedure, Xenotransingation, is still experimental, but doctors in New York performed kidney and pig transplants in the tissues that pass to see how the fare is.
Last year, two genetically modified alive patients received. The adjustments removed the genes of harmful pigs, and the broken viruses that lie in wait for the genome of pigs that could re -wake up and cause infections, decisively, added human genes to make them more compatible.
Members were provided by egenesis, a biotechnology company that George’s Church has co -founded the Harvard University Church. He said that both patients were “healthy and happy” and not on dialysis anymore.
The company has the approval of the US Food and Drug Administration to conduct a clinical trial in 33 patients. “If these 33 are in addition to the first, it will be expanded for all the population,” said Cherish. “The number of pigs that we have to make is a small part of the consuming number every year to cut bacon and pork.”
At the present time, the company focuses on the kidneys, liver and heart, but the church expects to provide every member and tissue that is usually planted from man to man.
Agricultural pigs for organs are a practice that will have critics, but more radical and morally enforced proposals on the table. Earlier this year, the researchers said that developments in stem cell biology and artificial uterine technology can enable scientists to create Spare human bodies.
This process is complicated, but it involves making a fetus from the patient’s cells, disrupting the genes needed to form a brain, and developing it in an artificial uterus. The result is a human body without a brain, made to provide organs to his genetic father.
“There is an Ike factor,” says Charston Charlesworth, a post -PhD researcher at Stanford University. “For many people, the arm is fine, a liver fine and a fine of the kidneys. But when you have everything except for the brain, it feels more human similarities and people feel anxious.”
The church has great hopes for another approach. The liver and other organs can be adjusted genetically, inside or outside the body, to be infection resistance and the release of anti -aging compounds such as proteins that help the body to maintain good health. “You turn the organ into an anti -aging treatment,” he says. If this is done on the site, it avoids the need to perform a major surgery, anti -rejection drugs and human beings without a head.
Is it born that people live this century to 150? “Perhaps someone will read your article is the last person who does not have the option to live up to 150,” says Cherish. “It will be sad to be the person who just lacks, and I have a feeling that I am one of these people.”
