With the rapid development of science and technology, many of today's "science fiction plots" may gradually become a reality. Recently, scientists in the field of anti-aging have made a new breakthrough, Israeli scientists in the experiment let 13 sixty-year-old people (average 68 years old) experience a "reverse growth".
Thirteen elderly people inhaled hyperbaric oxygen, or lost their age by 25 years
Israeli scientists selected 13 elderly people as research subjects, their average age is about 68 years old, and their physique is no different from that of ordinary elderly people, all of whom suffer from diseases that are highly prevalent in the elderly, such as hypertension and diabetes.
Under the arrangement of scientists, these elderly people enter the high-pressure state to breathe pure oxygen, and they have to inhale 5 times a week for 90 minutes each time. Professor Shai Efrati, who led the experiment, which lasted for 6 months, chose a more direct skin sampling method and excluded the effects of ultraviolet rays on the skin in order to allow people to more clearly observe the changes in these elderly people.
There is no precedent for histological testing in this way. After multiple sample extractions and comparisons, it was found that the physiological indicators of the skin varied greatly.
The detection found that the senescent cells were reduced by one-fifth, and combined with the conclusions of Professor Shai Efrati's previous hyperbaric oxygen experiments, the physiological age of these elderly people may be reduced by 25 years.
For senescent cells in the human body, they will continue to release "pro-inflammatory factors", so that healthy cells are infected, and will stay in the body for a long time, and over time accumulate a large amount in the body, so that the rate of aging of the body is accelerated. Therefore, the elimination of senescent cells is considered a viable means of maintaining youthfulness.
Moreover, through microscopic imaging observation, it was also found that the skin showed a youthful state. The extracted skin samples increased the length of the elastic fibers by more than 3 times, and the density of collagen fibers increased by more than one-tenth, and the two are important substances to maintain skin elasticity and avoid the appearance of loose and falling skin, and they show signs of improvement that the original aging skin has undergone some "rejuvenation" changes.
The degree of technology is high, and the rich circle is popular first
Of course, this 6-month trial was not smooth sailing, there were also 2 accidents, an old man accidentally caused a local infection when taking a skin sample, and returned to normal after 3 days of conditioning. There is also an elderly person who may have an ordinary barotrauma due to a cold, and he has also recovered after simple treatment. It can be seen that the hyperbaric oxygen chamber as a whole is still reliable in terms of safety.
Hyperbaric oxygen as a physiotherapy method, in fact, has a long history, to now have a relatively mature technology, in a number of hospitals to achieve landing, play a role in medical assistance. Hyperbaric oxygen can promote the lysis of oxygen in cells, help heal wounds, soothe inflammation, and improve immunity. After years of research, scientists have discovered its potential to delay aging, and for this reason, it has also promoted the domestic O2ark hyperbaric oxygen chamber and other landing products, and many people are eager to try it.
However, the O2ark hyperbaric oxygen chamber is highly priced, conservatively starting at 300,000, which is often found in the circle of the rich who have more money and spare their lives. Pop singer Justin Bieber has said she has bought 2 hyperbaric oxygen chambers and wants to keep it in its current state. Hyperbaric oxygen chambers have also been purchased by some well-known health clubs and hotels to improve their service standards and competitiveness, and they were once ridiculed as only affordable by the rich.
In fact, in terms of the current technology to delay decay, the use threshold is not only the hyperbaric oxygen chamber. Gambling king He Hongshen accidentally fell and survived to the age of 98 by hitting 860,000 brain injections every day. Li Ka-shing, a 94-year-old Hong Kong rich man, also spent more than 1.5 million yuan a year to try the "Wlnad" product developed by Harvard in order to disobey the elderly. It is understood that the substance has been listed as an important scientific research project by many countries, mainly to alleviate the medical burden caused by aging from the physiological level.
However, according to a domestic east, a cat and other channels can be found that "Wlnad" such stretch life supplements, although the use threshold has dropped by more than 95%, but still mainly for high-net-worth people, the landing of related technologies still needs a long time.
The clichéd "aging" may become a thing of the past
At this stage, anti-aging technology has made great progress, even if many results are still just out of the laboratory, and have not achieved a real sense of practicality and popularization, but this may be a process that needs to be experienced in the development of science and technology.
Nowadays, the scientific research of the world is catching up with me, and the Chinese Academy of Sciences on the mainland has discovered a new aging gene KAT7, which has cleared this gene and extended its lifespan by a quarter; Nobel Prize scientist Shinya Yamanaka has made a breakthrough in the field of gene editing technology, and the cells of 114-year-old people have been successfully restored to the "0-year-old" state.
People's cognition of aging may have stayed at the level of "irreversible" and "irreversible" in the past, and with the advent of many scientific research technologies, perhaps within the 21st century, aging will become a common disease, and the era of everyone's hundred years old is not far away from us.
