A group of researchers from the United States has developed a new technology that can restore damaged arteries. At the heart of technology - a microscopic drone - a special device, whose dimensions are thousands of times smaller than the tip of a person's hair. A lot of such drones use the protein preparation annexin A1, which helps restore damaged areas of the arteries.
The research group has already conducted tests on laboratory animals, which, according to the authors, showed good results.
Specialists from America used microscopic drones for tissue repair in damaged large arteries. Devices can easily penetrate into large arteries and, if necessary, restore damaged areas, which will allow to reduce the likelihood of developing a heart attack, especially in persons at risk.
Microscopic drones are essentially nanoparticles, created to destroy cholesterol plaques. Since the dimensions of the drones are microscopic, the specialists made them from soluble plastic.
According to the developers themselves, this technology will make a breakthrough in the treatment of diseases of the cardiovascular system.
Nanodrons contain a protein natural preparation, which specialists have obtained from the protein of annexin A1, which participates in the repair of damaged tissues.
Tests in laboratory animals have shown that treatment with nanoparticles after five weeks can reduce the number of cholesterol plaques by several times. As a result, the probability of clogging blood vessels is significantly reduced. In addition, nanodrons can reduce the level of active oxygen species.
Within the framework of the study, specialists successfully used the new technology on laboratory rodents and expressed the hope that the new treatment method will show the same results in people.
Omid Farokhazad, a leading expert of the research project, said that their work was the first, thanks to which nanoparticles coped with atherosclerosis in the body of laboratory rodents. Dr. Farokhazad also stressed that nanodrons can be used not only to treat diseases of the cardiovascular system, but also to use them to restore other tissues of the body. But, despite the fact that the technology has shown good results, it requires further research, since rodents, even with atherosclerosis, do not experience a heart attack.
It is worth noting that the drones were not first used by specialists. For example, in the Netherlands, a proposal was made to use drones for medical purposes and make an ambulance really fast.
A drone that moves at a speed of 100 km / h can reach its destination in a few minutes. The young technologist created a device in which he built a defibrillator and the necessary tools that are required to provide the first emergency aid for a heart attack. Also, a camera is built into the drone, thanks to which physicians can control the process at a remote distance.
