Russian scientists invent new cancer treatment method
19 Dec '11
Scientists of the D. Mendeleyev University of Chemical Technology of Russia have developed one of the most efficient methods for treating inoperable metastasized and primary liver cancer using microspheres from yttrium aluminum silicate glass, science and technology site STRF.ru reports.
Usually such microspheres are used in radio therapy as a means of transporting rays to internal organs of a human, damaged with malignant tumor.
Before injection into a human body microspheres are subject to ray treatment with heat neutrons in nuclear reactor. As a result of radiation a short-living isotope Y90 with a 64.1-hour half-life is formed in such glasses, sufficient for delivering medicine to clinic and performing treatment. Y90 also possesses nuclear-physics characteristics, comfortable from the point of view of therapeutic applications.
The medication has already been tested on people. In the nearest future a complex to produce micro-balls with minimal impurity content. This will replace import medications, which sometimes cost up to $12,000 per dose, with a cheaper Russian analogue. Besides, national microspheres have a higher content of yttrium oxide, if compared with similar products of foreign produce (specifically, such medications are made in Canada).
The invention of Russia scientists received a Grand Prize from the best innovative exposition at the international forum on intellectual property “Expopriority’2011”, held in Moscow on December 7-9, 2011.
The D. Mendeleyev University of Chemical Technology of Russia is one of the oldest and known universities in the country, was founded in 1880 as a technical university. The University trains professionals, capable of working at the industrial companies, science and research and educational institutions, government agencies, as well as innovation business-structures.
