AIM: this study aims to estimate significance of the descriptive dental epidemiology in evaluation of the long-term effect of the Community program for prevention of dental caries.METHODS: The descriptive dental epidemiology data of DMFT 12-year-old children in Belarus and Russia were analyzed since 1961 to 2014.RESULTS: Meta-analysis of publications indicated that prevalence of dental caries has dropped from average 3.7-3.8 DMFT at baseline to 2.2-2.6 DMFT after 20 years of the programs implementation in Belarus and Russia accordingly. However, during last 5-6 years a negative trend was assumed.CONCLUSION: Based on long-term DMFT monitoring, the community programs in Belarus and Russia were effective in reducing dental caries by 30-40% for about 30-years period. However, the observed trend was not stable perhaps due to insufficient scientific support of programs.Цель исследования — оценка информативности данных описательной эпидемиологии в определении эффективности программ профилактики и тенденций заболеваемости детей кариесом в России и Беларуси. Проведен метаанализ данных многолетнего мониторинга среднего КПУ постоянных зубов у 12-летних детей Беларуси и России. За 20-летний период систематического мониторинга наблюдалось снижение индекса КПУ зубов у детей со «среднего» (3,7—3,8) до «низкого» уровня: в Беларуси и РФ соответственно 2,2 и 2,6. В последние годы ряд эпидемиологических исследований указывают на рост заболеваемости детей кариесом в обеих странах. Заключение: многолетние данные описательной эпидемиологии позволили определить, что программа профилактики, разработанная в СССР в 1988 г., была эффективной в снижении интенсивности кариеса зубов у детей. Рост заболеваемости в последние годы, возможно, обусловлен недостаточной научной поддержкой программ профилактики.

The objective of the present study was to choose the optimal method for the modeling of the glance of a bullet after hitting a target under conditions of the laboratory experiment. The study required the designing and construction of an original device for the modeling of the rebound effect of a light-firearm shot under experimental conditions. The device was tested under conditions of the laboratory experiment. The trials have demonstrated the possibility of using barriers of different weight and dimensions in the above device, their positioning and fixation depending on the purpose of the experiment, dynamic alteration of its conditions with due regard for the safety and security arrangements to protect the health and life of the experimenters without compromising the statistical significance and scientific validity of the results of the experiments.Цель исследования - выработка оптимального способа моделирования рикошета пули в условиях лабораторного эксперимента. Разработана и создана оригинальная установка для моделирования рикошета огнестрельного снаряда в экспериментальных условиях. Данная установка апробирована в ходе лабораторного эксперимента. Доказана возможность использования в установке преград различных массы и размера, расположения и фиксации в соответствии с задачами эксперимента, динамического изменения его условий с обеспечением безопасности жизни и здоровья исследователя без снижения достоверности и научной обоснованности результатов эксперимента.

We studied a new method of treatment of amyotrophic lateral sclerosis with autologous mesenchymal stem cells. Autologous mesenchymal stem cells were injected intravenously (intact cells) or via lumbar puncture (cells committed to neuronal differentiation). Evaluation of the results of cell therapy after 12-month follow-up revealed slowing down of the disease progression in 10 patients in comparison with the control group consisting of 15 patients. The cell therapy was safe for the patients.

We have studied the effect of in vivo irradiation of blood by radiation at different wavelengths (254 nm, 632.8 nm, and 670 nm), which can be absorbed by blood, on the absorption spectra and gas composition of venous blood for individual patients. We have determined the differences in short-term and long-term changes in both spectral characteristics and the gas composition of blood induced by irradiation. During and immediately after irradiation, for all the patients we observed an increase in the partial pressure of oxygen and a decrease in the partial pressure of carbon dioxide in venous blood. After irradiation was completed, the changes in the partial pressures of blood gases were different for different patients: the gas pressures both increased and decreased, depending on the photo-induced changes in the level of hemoglobin oxygen saturation in venous blood. © 2013 Springer Science+Business Media New York.

Composite stomatological light-cured materials with a polymer matrix, bonding layer and inorganic filling (glass) are examined. The requirements imposed on these materials by modern therapeutical stomatology are indicated. The composition and some technological aspects of the production of the new material are presented. An investigation of the physical-mechanical properties of the new composite material (strength, water absorption, polymerization depth) showed that these indices are on par with the best foreign analogs. © 2014 Springer Science+Business Media New York.

We have used EPR dosimetry on tooth enamel to show that the combined effect of x-rays with effective energy 34 keV and gamma radiation with average energy 1250 keV leads to a significant increase in the reconstructed absorbed dose compared with the applied dose from a gamma source or from an x-ray source or from both sources of electromagnetic radiation. In simulation experiments, we develop an approach to estimating the contribution of diagnostic x-rays to the exposure dose formed in the tooth enamel by the combined effect of x-rays and gamma radiation. © 2014, Springer Science+Business Media New York.

Based on study of spectral and relaxation characteristics, we have established that paramagnetic centers induced in tooth enamel by x-rays and gamma radiation are identical in nature. We show that for the same exposure dose, the intensity of the electron paramagnetic resonance (EPR) signal induced by x-radiation with effective energy 34 keV is about an order of magnitude higher than the amplitude of the signal induced by gamma radiation. We have identified a three-fold attenuation of the EPR signal along the path of the x-radiation from the buccal to the lingual side of a tooth, which is evidence that the individual had undergone diagnostic x-ray examination of the dentition or skull. We have shown that the x-ray exposure doses reconstructed from the EPR spectra are an order of magnitude higher than the applied doses, while the dose loads due to gamma radiation are equal to the applied doses. The data obtained indicate that for adequate reconstruction of individual absorbed doses from EPR spectra of tooth enamel in the population subjected to the combined effect of x-radiation and accidental external gamma radiation as a result of the disaster at the Chernobyl nuclear power plant, we need to take into account the contribution to the dose load from diagnostic x-rays in examination of the teeth, jaw, or skull. © 2010 Springer Science+Business Media, Inc.
