Abstract P-43: Effect of Glucocerebrosidase Dysfunction on the Pool of Plasma Exosomes of Patients with Gaucher Disease

Background: Extracellular vesicles (EVs) are small membrane vesicles released from different types of cells. EVs are found in many human biological fluids. Exosomes are a subtype of EVs that are released by the fusion of multivesicular bodies with the plasma membrane. This type of vesicles is characterized by specific exosomal markers. Exosomes extracted from peripheral body liquids could have specific properties associated with different physiological conditions as well as human disorders, including neurodegenerative diseases. Gaucher disease (GD) – is the most common form of lysosomal storage disorders caused by mutations in the glucocerebrosidase (GBA) gene. Lysosome functionality is critical for the regulation of extracellular vesicle secretion and content. In model animals, the inhibition of glucocerebrosidase has been shown to increase the secretion of extracellular vesicles in brain tissues. Amount evaluation of EVs and their size in the biological fluids of patients with GD has not been early performed; therefore, it is unknown whether lysosomal dysfunction found in GD patients influences the plasma pool of EVs. The aim of this study was to evaluate the amount of blood plasma EVs in patients with GD and their characterization for morphology and size. Methods: EVs were isolated from the blood plasma of 8 GD patients and 8 controls by ultracentrifugation, and were characterized using cryo-electron microscopy (cryo-EM), nanoparticle tracking analysis (NTA), and dynamic light scattering (DLS). Also, the presence of exosomal markers CD9, CD63, CD81, and HSP70 was analyzed by flow cytometry and western blot. Results: Here, it was first shown an increased proportion of exosome fraction in EVs from plasma of GD patients compared to controls by DLS and cryo-EM (p<0.001) that was confirmed by mode size detected by NTA (p<0.02). Moreover, an increased number of double and multilayer vesicles in plasma EVs from GD patients was demonstrated by cryo-EM. We also detected an increase in the expression of exosomal markers on the surface of vesicles from the blood plasma of patients with GD compared to controls. Conclusion: Here, we firstly report that the exosomes obtained from the blood plasma of GD patients have a larger size and altered morphology. Thus, we have shown that lysosomal dysfunction in GD patients leads to a striking alteration of blood plasma extracellular vesicle pool

New Genetic Markers for Molecular Typing of Bacillus anthracis Strains

Objective: Identification of new markers for the molecular typing of Bacillus anthracis. Materials and methods. The genomes of 16 B. anthracis strains from the collection of the Stavropol Research Anti-Plague Institute, 11 B. anthracis strains and 5 strains of Bacillus cereus from GenBank were investigated. The methods of in vitro and in silico analysis of canonical and whole-genome single nucleotide polymorphisms (SNP), genome regions with variable number of tandem repeats (VNTR) were used for the analysis. Results and discussion. It has been established that there are deletions and (or) SNPs in some of B. anthracis strains of the main genetic lineage B, within the homologous genes of the tri-cistronic operon gerH, which encodes spore germination proteins. gerA genes contain the Bams34 VNTR locus, the sizes of genes in different strains vary due to the different number of tandem repeats and the presence of indels, which suggests the variability of GerA spore germination proteins. In the area of reverse primer annealing, some of them have several SNPs or deletions, which makes impossible PCR amplification of the Bams34 locus. Previously not described VNTR locus, SNPs and indels in sequences of plasmids pXO1 and pXO2, as well as SNP in chromosomal gene of glycerol-3-phosphate transporter were identified. Two pairs of PCR primers for the variable regions of the plasmids were designed. VNTR-locus, SNP and indels in sequences of plasmids pXO1 and pXO2 are suitable genetic markers for the differentiation of typical virulent diplasmid strains belonging to the main genetic lineages of B. anthracis A, B and C. The allele T of SNP within chromosomal glpT gene is specific for one of two strains isolated during the outbreak of anthrax and distinguishes it from all other strains of B. anthracis

Проблемы риск-коммуникаций по вопросам радиационной безопасности: оценка информированности населения Санкт-Петербурга и Ленинградской области о деятельности атомной отрасли и его представления о факторах опасности

In 2016, St. Petersburg Research Institute of Radiation Hygiene named after Professor P.V. Ramzaev developed a Program for the radiation risk communication management for the adequate perception risks associated with the use of various technologies in the nuclear industry by the public. Carrying out sociological research is one of the stages of this program. The aim of the analysis presented in the article is to study the population’s awareness of radiation safety issues and its attitude to further development of the nuclear industry. The data used in this analysis is a part of a large sociological survey conducted in St. Petersburg and the Leningrad Region The sociological research was conducted by the method of a selective questionnaire survey among the adult population permanently residing in the territory of St. Petersburg and the Leningrad Region. The volume of the sample studied was 2369 respondents: 1006 in St. Petersburg and 1363 in the Leningrad Region, including Sosnovy Bor – 401. The analysis showed that the population of all the studied territories estimates the environmental situation as being mainly favorable. The residents consider the main environmental problems in all areas studied to be a collection, removal, storage, disposal of garbage, as well as air and water pollution. The population of the region is relatively poorly informed about the current projects in the nuclear industry. One-third of the inhabitants of the region perceives the Leningrad nuclear power plant as a source of danger. Respondents see the main danger in the possibility of an accident on it. There is a sharply negative attitude of the population towards the construction of radioactive waste disposal sites anywhere in the region. According to the results of the study, it can be concluded that the population of the studied region is poorly informed about the existing radiation situation and the nuclear industry projects. It requires an optimization of the choice of methods for risk communication. В 2016 г. в Санкт-Петербургском научно-исследовательском институте радиационной гигиены имени профессора П.В. Рамзаева была разработана Программа организации информационной работы с населением по вопросам радиационной безопасности для адекватного восприятия населением риска, связанного с применением в атомной отрасли различных технологий. Одним из этапов этой Программы является проведение социологических исследований. Целью представленного в статье анализа части большого социологического исследования, проведенного в г. Санкт-Петербурге и Ленинградской области, является изучение информированности населения по вопросам радиационной безопасности и его отношение к деятельности по дальнейшему развитию атомной отрасли. Социологическое исследование проведено методом выборочного анкетного опроса среди взрослого населения, постоянно проживающего на территории г. СанктПетербурга и Ленинградской области. Объем исследованной выборки составил 2369 респондентов: в г. Санкт-Петербурге – 1006, в Ленинградской области – 1363, в том числе в г. Сосновый Бор – 401. Анализ полученных результатов показал, что население всех исследованных территорий оценивает экологическую обстановку как преимущественно благоприятную. Основными экологическими проблемами на всех изученных территориях жители считают сбор, вывоз, складирование, утилизацию мусора, а также загрязнение воздуха и воды. Население региона относительно слабо информировано об актуальных проектах атомной отрасли. Треть жителей региона воспринимает Ленинградскую атомную электростанцию как источник опасности. Основную опасность респонденты видят в возможности аварии на ней. Отмечается резко негативное отношение населения к строительству пунктов захоронения радиоактивных отходов в любом месте региона. По результатам исследования можно сделать вывод, что требует оптимизации выбора методов информационной работы с населением.

ОБЪЕКТИВНОЕ И СУБЪЕКТИВНОЕ В ОЦЕНКЕ ОПАСНОСТИ ПОСЛЕДСТВИЙ МИРНЫХ ЯДЕРНЫХ ВЗРЫВОВ НА ПРИМЕРЕ ОБЪЕКТА «ДНЕПР»

The purpose of research was to assess the dynamics of the changes during the five-year period (from 2008 to 2013) of the radiation situation in the territory adjacent to the places of the peaceful nuclear explosions of the “Dnepr” series in the Murmansk region, the analysis of information environment of the subject in the Internet and the study of the population public opinion.Gamma-radiation dose rate registered in the investigated territory in 2013 (140 – 180 nSv/h) corresponded to the natural radiation background, characteristic for the Khibiny. The average content of 137Cs in soil is comparable to the level of the global fallout contamination. Levels of the artificial radionuclides concentration in the samples of natural foodstuffs (mushrooms and berries) were found in 2013 to be much lower than corresponded permissible levels. Values of the 3H specific activity for the water samples from the surface and underground sources sampled in 2013 decreased more than in 1,5 times in comparing with 2008 and have not exceeded the interventional level – 7600 Bq/kg. Exposure doses estimated for the critical group of population Exposure doses estimated in 2013 for the critical groups of population have not exceeded the dose limit adopted in RSS-99/2009. The interest of population to the mentioned problem has not been pointed out on the basic of the analysis of publications electronic versions in mass media for 2013. The comparative analysis of the results of the survey showed that level of public concern over the radiation environment in their places of residence has been low in 2008 and even lower in 2013. With a low level of the knowledge concerning radiation respondents found their significant interest for the issues relating radiation, its effects on the health and radiation protection measures.Along with the radiation-hygienic monitoring, it is necessary to conduct regular activities aimed on the population informing about the radiation situation on the basic of the significant data obtained from the responsible agencies specialists.Цель исследований состояла в оценке динамики изменений за пятилетний период (с 2008 по2013 г.) радиационной обстановки на территории, прилегающей к местам проведения мирных ядерных взрывов серии «Днепр» в Мурманской области, анализе информационной среды по данной проблеме в Интернете и изучении общественного мнения населения.Регистрируемые в 2013 г. мощности дозы гамма-излучения на обследуемой территории (140–180 нЗв/ч) соответствовали естественному радиационному фону, характерному для Хибин. Средний запас 137Cs в почве сопоставим с уровнем глобальных выпадений. Уровни загрязнения техногенными радионуклидами проб природных пищевых продуктов (грибов и ягод) в2013 г. оказались намного ниже допустимых уровней. Значения удельной активности 3H в пробах воды поверхностных и подземных источников в2013 г. снизились более чем в 1,5 раза по сравнению с2008 г. и не превышали уровень вмешательства – 7600 Бк/кг. Оцениваемые дозы облучения критических групп населения в2013 г. не превышали предела доз для населения, определенных НРБ-99/2009. На основании анализа электронных версий публикаций за2013 г. в средствах массовой информации не отмечено интереса населения к данной проблеме. Сравнительный анализ результатов анкетирования показал, что уровень беспокойства населения по поводу радиационной обстановки в местах их проживания был низким в2008 г. и еще ниже в2013 г. При низком уровне знаний о радиации респондентов обнаружен их значительный интерес к вопросам, касающимся радиации, влияния ее на здоровье и мер защиты от нее.Наряду с радиационно-гигиеническим мониторингом, необходимо проведение мероприятий, направленных на регулярное информирование населения о радиационной обстановке на основании достоверных сведений, полученных от специалистов ответственных ведомств
