Vol 6 Chapter 2945: The Secret of Human Aging

Latest URL: Seeing the disappointment of everyone in the audience, the corners of Wu Hao's mouth twitched slightly. What he wants is this kind of effect, it's like a street vendor suddenly made a delicious food, and after showing it off to the onlookers, he said he wouldn't sell it. I can stand it.

"You don't have to be too disappointed. This smart bionic robot dog will not be too far away from meeting you. After the press conference, these smart bionic robot dogs on the stage will also meet and interact with you in the park. Those who are interested can stay and participate.”

After listening to Wu Hao's words, everyone looked a little better, and they were more attracted by the experience activities after the press conference. After all, whether it is from the technical level or the appearance of these intelligent bionic robot dogs, they are very good. attractive.

Well, this is the intelligent bionic robot dog we brought to you, I hope you like it!

After finishing speaking, amidst applause, the large screen floating in the air appeared again, and began to play a short video about this intelligent bionic robot dog.

As for Wu Hao, he also took the opportunity to issue a password to let these robot dogs leave the field. As for him, he took the opportunity to drink a saliva and take a short rest. This talk is really a bit tiring.

After the short film was over, Wu Hao returned to the stage to stand firm, and then said with a smile: "Everyone knows that we have always attached great importance to the investment and research and development in the field of biomedical technology. Under our continuous encouragement, after years of development, We have also achieved some results in this field.”

coming!

Everyone couldn't help laughing bitterly. Is this a little achievement? If it's just a little achievement, then what are the achievements of those pharmaceutical giants?

It can be said that Haoyu Technology has far surpassed those pharmaceutical giants in the field of biomedical technology in recent years.

At present, it already has a huge influence in the field of international biomedical technology, and this has also broken the monopoly of developed countries such as Europe and the United States in this field, and created a precedent for the domestic biomedical technology industry.

But now in Wu Hao's mouth, these are just some achievements, this modesty is a bit too much, hypocrisy!

"The purpose of our entry into the field of biomedicine is actually very simple, that is, to be able to cure more people and save more patients afflicted by the disease. So we have been exploring in this field, how to prolong the life span of our human beings, how to Let us humans stay healthy and avoid diseases.

After several years of hard work, we have indeed achieved some results in the field of biomedical technology, whether it is our intelligent bionic artificial organ tissue technology, or our bio-3D printing technology, or our biopharmaceutical technology, it can be said that It has saved countless patients, including many patients who were sentenced to death. We have successfully overcome many diseases, even many terminal diseases.

According to a latest medical research report we have obtained, with the blessing of our existing technologies, we can extend the natural life span of a person to about one hundred years old. "

coax!

After listening to Wu Hao's words, there was a sensation in the audience. This news is no less than a bomb to everyone, making it difficult for everyone to digest for a while.

The people who reacted first looked at the young Wu Hao on the stage and couldn't help but shook their heads. They felt that Wu Hao really dared to say it. Although they admitted that Haoyu Technology's biomedical technology is very advanced, they can't say that it can treat human nature. Extending the lifespan to one hundred years is too big a word, and it will be controversial.

Seeing the reactions of everyone in the audience, Wu Hao smiled slightly: "Of course, this is just an ideal age, because there are many factors that affect a person's life span, and it is too difficult to predict.

It can only be said that under normal circumstances, this goal can be achieved. However, it is still unknown whether this goal can be achieved. After all, our biomedical technology has only been around for a few years, and it takes time to accumulate and prove it. This is a very slow process full of too many uncertain factors. "

Speaking of this, Wu Hao turned around and said: "We have been studying how to prolong human life, how to keep people young and not aging.

In fact, this problem is also a subject of common research in the frontiers of our country's medical science. In these years of research, we have also found many reasons that lead to our human aging.

For example, in the most famous theory of telomere loss, scientists have discovered a small piece of DNA-protein complex at the end of our human eukaryotic cell linear chromosome, which is called telomere.

There are many main functions of telomere DNA. There are three main points. The first is to protect chromosomes from being degraded by nucleases; Retraction ensures complete replication of chromosomes.

After continuous research by scientists, it has been found that telomeres are related to cell aging. The older the cell, the shorter the telomere length; the younger the cell, the longer the telomere. Aging occurs when the function of a cell's telomeres is impaired, and when telomeres are shortened to a critical length, aging is accelerated and death approaches.

Secondly, cell division will shorten the telomere. Once it divides, it shortens a little, just like wearing away an iron rod. If only a stump is left, the cell is close to aging.

As you all know, UU Reading www.uukanshu.com The number of cell divisions in our human body is limited, generally about 50 times, and of course it is not limited to 50 times. The upper limit of human cell division is determined by the telomere in the cell, and the length of the telomere affects the cycle of cell division. After each cell division, telomeres shorten due to wear and tear. When there are too many divisions and the telomeres are too short, the two ends of the chromosomes cannot be protected and the cells stop dividing. The number of divisions of normal human cells is limited, generally about 50 times. However, affected by various factors, the number of cell separations for different people is different, some may be longer, and some may be shorter.

According to the famous Hayflick limit theory, the cells in the human body will die due to self-produced toxins after about 50 divisions. But it is not that the longer the telomere, the longer the life span. Although the telomere has a certain relationship with the life span, it is not the only factor that affects the life span. Such as disease, air pollution, and even excessive stress may lead to premature cell apoptosis. At present, the clinical medical community tends to think that telomeres are only one of the causes of human aging and death.

In addition, scientists have also discovered that there is an enzyme in the cell that synthesizes telomeres. The replication of telomere cannot be catalyzed by classical DNA polymerase, but by a special reverse transcriptase—telomerase.
