From the pig liver can extract more valuable than gold, worth 500 million yuan per kilogram! It can not only resist aging, but also prevent cell cancer. Yesterday, at the promotion meeting of the Biomedicine, Modern Agriculture and Food Technology held at the Science Fair, 8 new scientific research achievements appeared and sought cooperation. These new projects are closely related to our lives.
Yesterday, a special promotion meeting was held in Mianyang with the theme of biomedicine, modern agriculture and food technology. At the meeting, 8 new scientific research achievements appeared and they sought cooperation.
These new projects are all related to our lives. For example, the scientists invented the "slender" pediatric drug, the antibody drug "starved to death" cancer cells, and the future use of bioengineering technology to propose the use of metallothionein in pig liver to help humans delay aging and prevent cancer, use polymer materials as medical clothing. Can handle nuclear waste, etc. Liver Alchemy
MT scavenging free radicals "health killer" has a nemesis
MT, the scientific name of metallothionein, a substance that can help humans delay aging and prevent canceration of cells, is more expensive than gold. A kilogram is worth 500 million yuan, and it has attracted worldwide attention.
“This valuable thing can be extracted through the liver.†Yesterday, Sun Yali, the old expert technical center of the Chinese Academy of Sciences, released the above-mentioned scientific and technological achievements, and stated that “this wonderful flower will be medical Health, beauty, makeup, etc. bloom brilliant brilliance."
Why can MT have such magical effect? Let us first understand from the "health killer" free radicals. Free radicals are atoms or molecules that have unpaired electrons. They are widely present in the human body and in vitro. If there are too many free radicals in the body, they will break the balance and cause disease or aging. It is understood that the cooking fumes, smoked cigarettes, and automobile exhausts are all rich in free radicals.
"MT can eliminate excess free radicals in the human body." Sun Yali said that the cosmetics that ladies love to use "antioxidant anti-aging" function contain MT, use it to remove oxygen free radicals in the human body, to reduce the body and the skin The purpose of aging.
In addition, it can also be used as a heavy metal antidote to participate in cellular DNA damage repair, enhance the body's response to various emergencies, prevent cell cancer, etc. It can be widely used in medicine, food care and cosmetic additives, genetic engineering Reagents, chemicals, environmental protection, animals, agriculture and other experimental supplies.
Chinese scientists have invented methods for extracting MT from pig livers. For every 100 piglets slaughtered, 22.5 kg of pig liver was removed and 50 grams of MT can be produced. Annual production of 100 batches, can extract 60% to 70% crude 5 kg, according to the domestic calculation of 3,000 yuan per gram, the output value can achieve 15 million yuan.
“As far as the actual level of Chinese consumers is concerned, their annual demand is about 50 to 60 kilograms, and the current actual output is less than 10 kilograms per year.†Liu Yali said that due to its difficulty in extracting technology, the international quoted price is 66 dollars per milligram. About RMB 500 million per kilogram. “Our technology is very mature and we hope to find people of insight to develop together.†In his opinion, they prefer to jointly develop “gold mines†compared to technology transfer. Technology Q & A What is MT?
Sun Yali said that MT is a low molecular weight, rich in cysteine, an active protein that specifically binds heavy metals. What is its role?
Sun Yali said that it is the most effective free radical scavenger and has a strong antioxidant effect. What is a free radical?
"Scientists call these atoms or molecules with unpaired electrons free radicals." Sun Yali said that in a world of atoms, there is a special rule that is, as long as there are more than two atoms together Its peripheral electrons must be paired. If they are not paired, they must search for another electron and make themselves a stable material. He compares free radicals to bachelors in human society. If he is over- or out of control, he will become a “single citizenâ€. Minimal pills
The medicine is thinner than the sand and the baby is no longer afraid
The baby is ill and medication is a big problem. Smell the smell of medicine, the baby may shake his head and do not want to swallow it; even if the drug is stuffed into the baby's mouth, but the bitter taste may also prompt the baby to spit it out; that strange taste may even make the baby The digestive tract is irritated and vomits during the medication.
Yesterday, a Henan science and technology company released a "preparation of children's pharmaceutical preparations" technology. The biggest advantage of this technology is that a thin film can completely cover the taste of drugs, allowing the size of the drug to shrink to a smaller extent than sand grains, and it can also use slow-release technology to control its release position.
"After the technology is widely used in children's drugs, parents will no longer worry about the difficulty of taking medicine." Sun Weidong, the company's official in an interview with Huaxi Dushi Bao, said that the vast majority of medicines on the market are traditional. As a result of technology, a large amount of sucrose, flavors and other excipients are used to cover the taste of medicinal drugs, resulting in a large amount of drugs. This new technology uses polymer materials as pharmaceutical excipients, not only can completely cover the smell of medicine, but also greatly reduce the volume of medicine.
For example, he said, a real-suspension drug with a net weight of 60 grams has only two grams of weight, and the accessories are nearly 30 times that of drugs. With the new technology, the excipients can be controlled at 3 to 5 times the amount of raw materials. between.
With medicines made with new technologies, moms and dads feed their babies. Adding only a small amount of sugar in the boiling water will allow the baby to take it comfortably and happily.
According to Sun Weidong, at present, this technology has just been developed and it fills the gap in this domestic technology. Yesterday was the first time that they released information to the public. They hope that this technology will find partners in Sichuan. He predicts that medicines produced using this technology as soon as five years from now can be listed. Anti-cancer new party
Block tumor-repleting antibody drugs "starve to death" cancer cells
“The old ancestors said that they would die without fighting. The war would not necessarily kill the enemy but could also cut the supply. This kind of antibody against tumors is this principle.†Zhang Dezheng, Institute of Biophysics, Chinese Academy of Sciences Tell everyone that the traditional cancer treatment technology is to kill cancer cells, and the means of their new drugs is to "starve the dead cancer cells." This new drug for treating tumors, called antibody huAA98, can block the supply of tumor blood vessels so that the tumor cannot grow up and it cannot cause harm to the body. In order to make everyone understand the principle of the operation of this drug, Zhang Dejun specifically described the principle of tumor growth in popular terms.
"Like a person grows up to eat, the tumor grows also to have a meal, the tumor meal comes from the blood vessel that grows inside. This kind of blood vessel can provide the nutrition." Zhang Dezhao says, the antibody huAA98 can block the tumor blood vessel supply, through Destruction of the blood vessels causes abnormal blood vessels, which cuts off oxygen, blood, and nutrient supply to the tumor. In addition, the traditional therapeutic technology can kill normal cells and affect the body's immune system. And this antibody only targets specific cancer cell molecules. And if you are targeting tumor vessels, you can treat different cancers by controlling the blood vessels.
At present, this antibody drug is in the preclinical phase. They have cooperated with a famous Sichuan hospital and have performed well on some animals.
Laser "consultation" coal mine risk "earthing" in advance
At the Mianyang Science Fair, disaster warning technologies developed by local companies and scientific research institutes in Sichuan, such as three-dimensional laser scanning and ultraviolet flame detection, are not only ahead of international standards, but also have been placed on dangerous industries in Chuanchuan and even China. Magic spell."
To make a regular physical examination of the bridge, you can always find the "lesions" in your body. An instrument called a three-dimensional laser scanning and measuring instrument can clearly understand the “pathogens†hidden in buildings, bridges and even coal mines, providing early warning for people's risk-relief operations. According to Shi Fuqiang, Dean of Sichuan Provincial Security Inspection Institute, 3D laser scanning technology is also called real scene replication technology. It changes the traditional single point measurement method and can provide 3D point cloud data on the surface of the scanned object. It is mostly used to obtain high precision and high accuracy. Digital terrain model for resolution. Taking the coal mine as an example, the gas in the coal mine can easily cause explosions. After the explosion-proof 3D laser scanning meter enters, gas scans are performed to establish a real-world model, dynamic analysis is performed, and risk factors are discharged in advance.
As the research institute that has taken the lead in comprehensively pioneering this technology, Sichuan Academy of Sciences has established the national key laboratories for key hazard detection and control at the provincial level with 3D laser scanning technology as the core. At present, this technology has been applied first in fields such as chemical parks, non-coal mines, cultural relics protection, earthquake sites, and transportation facilities, filling the gap in the field of three-dimensional measurement and control in China.
Photosensitive UV detection without deadly warning fire
At the Expo, the UV Flame Detector, a participating project brought about by a company in Xindu, Sichuan, is also attracting attention.
According to reports, the core hardware of the UV flame detector is a photo-sensitive tube. Before the fire broke out, ultraviolet light would be emitted from the flame or smoke, and the phototubes would receive the ultraviolet signal and undergo data processing to send the fire warning to the monitoring equipment.
The detection range of the UV flame detector varies depending on the model and range. Indoors up to several hundred square meters, outdoor higher, up to thousands of square meters. Basically, 360 degree no dead angle monitoring can be done. It is reported that the technology of UV flame detector has been very mature in Japan. The Xindu company was independently researched and developed after studying in Japan. It is different from the domestic technology that directly introduced Japan.
It is understood that the product has been tested in schools, research institutes and other places. The next step is to promote in the market.
