Worms have the ability to find people 15 types of cancer
Source:
Today, the diagnosis of cancer using a variety of technologies. As a rule, in the current hospitals, this is done using a CT scan, but sometimes cancer can be detected by . Recently, Japanese scientists have learned to diagnose cancer using roundworms Caenorhabditis elegans, which are also known as nematodes. No, to conduct a study of these tiny creatures don't need to swallow. It is enough to take the tests and let the experts to put the worms next to the urine samples. Observing the behavior of worms that can with 85% accuracy find out a person has cancer or not.
About the new technology of cancer diagnosis was described in a scientific publication . It was called N-NOSE, which stands for Nematode-NOSE (eng. "nose nematodes"). The study is only 90 dollars at the current exchange rate is about 6 000 rubles. Development of the technology was carried out from 2015 and now a new method of cancer detection is used in some clinics in Japan. The novelty has already interested representatives of the European hospitals, but it needs improvement.
So look round worms of the species Caenorhabditis elegans
How to detect cancer?
A New method of cancer detection is quite simple. The patient takes a urine sample, a sample of which is placed in the area of the Petri dish. Then, in the middle of the laboratory vessel is placed millimeter worms Caenorhabditis elegans, fed by E. coli. Scientists have long noticed that nematodes tend to move to attractive smells and to keep away from unpleasant smells. So, in the course of testing based on biological samples from 17 hospitals in Japan, researchers found that worms usually chosen closer to the urine of people with cancer, and biological samples from healthy people stay away.
Thanks to the technology of N-NOSE can be quite accurately know a person has cancer or not. In the future, scientists want to conduct genetic modification of worms, so they began to approach the urine samples of people with certain types of cancer. In the future, technology will allow you to recognize up to 15 types of cancer, including trudnoudaljaemye . At the same time technology is effective in the diagnosis of cancer of the gastrointestinal tract.
Determine the presence of cancer can even dog
The Ability to recognize cancer have not only roundworms, but also dogs. In 2017, the authors of the project said that for six months trained German shepherds Thor and Nikos smell clothes women with breast cancer. It later turned out that trained dogs can detect the disease with 100% accuracy.
As you can see, methods for the detection of cancer are many and varied. For the successful treatment of cancer it is important to detect them at an early stage. According to Japanese scientists, the method of round worms is one of the ways to detect cancer at the earliest stages of its development. Perhaps in the near future, this technology will help to significantly deadly diseases and healthy people on the planet will be much more.
