Named after scientists from Mordovian State University (MSU). NP Ogareva has developed a new method to increase the thermal effect of laser radiation without transforming the fiber, which can be used in cancer treatment. This will help reduce the cost of the procedure. The Ministry of Education and Science of the Russian Federation told socialbites.ca about this.
Laser therapy uses an intense, narrow beam of light to destroy cancer cells and is usually done through an endoscope, a narrow, lighted tube used to view tissue inside the body. Flexible endoscopes use thin optical fibers used individually or in bundles to deliver light to the therapeutic area.
“This therapy will eliminate superficial tumors for which removal by ablation (directed destruction using laser radiation or high-frequency current) is not contraindicated. In this case, the fabric will be heated to temperatures sufficient for it to vaporize and char. For other types of tumors, such as melanoma, heating will not be as important and will “It will be carried out to temperatures that will cause the death of benign cells.” Materials from Moscow State University told socialbites.ca. NP Ogareva Svetlana Khrushchalina.
Preliminary experiments on mice showed that treatment using a suspension of ytterbium-containing nanoparticles and laser radiation with a wavelength of 980 nm had an antitumor effect against melanoma. By day 13 after treatment using particles, inhibition of tumor growth in animals was two to three times higher than in animals treated without the use of particles (laser radiation alone).
The overall cost of the process will be lower, as it will be possible to reuse the fiber and reduce the power of the radiation provided.
