Center for X-ray, Synchrotron and Neutron Research opened in Russia
In Russia, in September 2024, the Center for X-ray, Synchrotron and Neutron Research was opened, which will become a key scientific platform for coordinating research in these areas. The new center was created on the basis of Novosibirsk State University (NSU) and is aimed at developing scientific projects related to the use of advanced radiation technologies. The center will work on long-term scientific projects and coordination of interdisciplinary research related to X-ray and synchrotron radiation, as well as neutrons. Read more here
Non-alcoholic wine has been created in Russia to protect the kidneys during X-ray
On April 21, 2024, Russian scientists from Belgorod State National Research University (NIU BelSU) announced the creation of non-alcoholic red wine, which can be used for medical purposes. Such a beverage may in particular protect a patient's kidneys during X-ray scanning.
Renal X-ray is a radiation examination method designed to assess the anatomical structure and functional state of the urinary system. Due to the harmful effects of ionizing radiation on the body, the intensity of the rays is strictly dosed, and the procedure is carried out only for medical reasons. The wine obtained by Russian specialists allows you to increase the safety of such a scan.
According to TASS, non-alcoholic wine is made using original technology from northern grape varieties specially selected and grown by geneticists of the university in the botanical garden of the National Research University of BelSU. The drink is said to be high in antioxidants. These substances protect the cells of the body from damage by reactive oxygen species.
 | Scientists of the Research Institute of Pharmacology of Living Systems of the National Research University of BelSU, as a result of experiments, proved that dealcoholized wine protects the kidneys from damage during X-ray contrast studies, the university said in a statement. |  |
According to the director of the Research Institute of Pharmacology of Living Systems of the National Research University of BelSU, Doctor of Medical Sciences, Professor Vladimir Pokrovsky, the antioxidant properties of the resulting drink prevent the development of endothelial dysfunction in systemic inflammation, including post-covid (COVID-19) syndrome. At the same time, the installation developed and assembled by the physicists of BelSU allows you to remove alcohol, not only preserving, but also increasing the volume of polyphenols and other useful substances.[1]
New materials for X-ray machines have been developed in Russia - they are non-toxic and cheap
On January 18, 2024, the Russian Scientific Foundation (RNF) announced that specialists from Lomonosov Moscow State University (MSU) have developed new safe materials for X-ray machines and ionizing radiation sensors. The obtained compounds effectively convert X-rays into visible light.
We are talking about scintillators - materials that emit visible light when X-ray or other ionizing radiation hits them. Such compounds are used in medicine and technology: in X-ray installations, inspection tapes at airports, quality control devices, etc. Russian researchers note that one of the most promising scintillators is considered to be hybrid manganese halides - compounds of manganese halides with halides of organic amines. They are cheap to produce and non-toxic, capable of absorbing and emitting light over a wide range of wavelengths. However, most hybrid manganese halides contain bulk organic molecules that reduce the density of the material and therefore its ability to absorb and convert X-rays. MSU specialists have proposed a way to solve the problem.
Scientists synthesized four manganese compounds with bromine and compact organic residues. During the studies, manganese bromide crystals were placed in organic solvents isopropanol and dioxane. The reaction proceeded at a temperature of + 70 degrees Celsius. As a result, crystals of the desired compounds precipitated from the solution a few days later.
Two of the four substances obtained glow in the red range, the other two in the green. Compared to hybrid manganese halides, the new materials are significantly more effective at converting the high-energy radiation incident on them into visible light. In particular, materials with bulk organic molecules have 100% absorption only if their thickness is several millimeters. In the case of new compounds, such an indicator is achieved using a submillimeter layer. Thus, the obtained substances can be used in miniature ionizing radiation sensors and new generation X-ray machines.[2]
2020: Dentistry in Russia warned about the consequences of the order of the Ministry of Health on the analysis of X-ray images
At the end of November 2020, the dental self-regulatory organization League sent a letter to Prime Minister Mikhail Mishustin warning about the consequences of the order of the Ministry of Health, obliging radiologists to analyze each medical report and draw up a protocol on it within 24 hours. This requirement also applies to dentistry.
The authors of the letter consider this requirement redundant and contrary to clinical recommendations, since such a procedure will increase the time of provision of the service and its cost. For example, in the treatment of the dental canal, three targeted images are taken.
| | If we describe each picture in order to move to the next stage, we will simply get bogged down, "said Sergei Pankiv, chairman of the League SRO and director of the Dentes dental clinic in Pskov. | |
According to him, radiologists who can describe a dental problem are difficult to find - this is not taught at medical universities.
The League's letter says that radiologists are now scarce specialists during the COVID-19 coronavirus pandemic. Their functions in dental clinics are often performed by nurses or doctors themselves, so the new requirements of the Ministry of Health put the need to recruit new employees. In addition, due to a shortage of radiologists, some clinics will close altogether, which will lead to a shortage of qualified dental care in Russia.
Dentists asked the prime minister and the Ministry of Health to amend the order and provide for X-ray examinations without drawing up a protocol by their specialists.
According to the data Rosstat for 2018, cited by the publication, 62,900 dentists and 22,200 radiologists and radiologists worked in Russia. In 2019 - 63,100 dentists and 15,600 dental staff, follows from the data of the analytical company BusinesStat.[3]
