Studing the Possibility of Application of Inorganic Sorbents in Radiochemical Analysis of 90Sr

Радиационный контроль стронция-90 является важным для решения природоохранных и экологических задач. Анализ литературных источников показывает нам, что методики по определению стронция-90 длительные, достаточно сложные и многостадийные, не исключены погрешности определения и заниженные результаты. Необходимо подобрать оптимальные условия определения данного изотопа, упростить анализ и ускорить, при этом снизить предел обнаружения до 0,1 Бк/л. В результате работы были изучены 5 сорбентов для предварительного концентрирования стронция. На основании сравнения сорбционных характеристик выбраны лучшие сорбенты, исследовали влияние рН на степень сорбции стронция. Для селективного выделения стронция-90 на тонкослойном сорбенте MnO2-ТАЦ изучили влияние рН и возможность отделения цезия-137.Radiation monitoring of strontium-90 is important for solving nature conservation and ecological problems. The analysis of literature sources shows us that the methods for determining strontium-90 are long, rather complicated and multi-stage, determination errors and underestimated results are not excluded. It is necessary to select the optimal conditions for the determination of this isotope, simplify the analysis and accelerate, while reducing the detection limit to 0.1 Bq/L. As a result of the work, 5 sorbents for preliminary concentration of strontium were studied. Based on a comparison of the sorption characteristics, the best sorbents were selected, and the effect of pH on the degree of strontium sorption was investigated. For the selective isolation of strontium-90 on a thin-layer MnO2-CTA sorbent, the effect of pH and the possibility of separating cesium-137 were studied.Исследование выполнено при финансовой поддержке РФФИ и Правительства Свердловской области в рамках проекта № 20-43-660055

Automatic selection of a subset size at vector fields construction

An algorithm for selection of the size of a correlation kernel at displacement vector field construction by the method of digital image correlation has been proposed. The algorithm has been tested on simulated and experimental optical images having different texture. The influence of the correlation kernel size and image texture on nose immunity at determining displacements has been studied. It is shown that the proposed algorithm allows to find this size providing the minimum error when determination of displacements and estimation of deformation

Apoptosis in the liver of male <em>db/db</em> mice during the development of obesity and type 2 diabetes

Obesity and diabetes mellitus are known to lead to the development of metabolic syndrome and non-alcoholic fatty liver disease (NAFLD). The mechanisms of programmed cell death are actively involved in maintaining cellular homeostasis along development of NAFLD. Proteins of the BCL-2 family are key regulators of physiological and pathological apoptosis. Homozygous males of BKS.Cg-Dock7mLeprdb/+/+/J mice (db/db mice) are characterized by progressive obesity and the development of type 2 diabetes mellitus (DM2) with severe hyperglycemia at 4–8 weeks and organ lesions at 8–10 weeks of age. The aim of this research was to study the expression of molecular cell regulators of apoptosis in liver cells of db/db mice males at different stages of obesity and diabetes development (at the age of 10 and 18 weeks). Immunohistochemical analysis (using the indirect avidin-biotin peroxidase method) and morphometric evaluation of the expression of the antiapoptotic protein Bcl-2 and the proapoptotic protein Bad in liver cells of studied animals at different stages of obesity and DM2 were carried out. An excess of the value of the Bcl-2 protein staining area over the Bad protein staining area was revealed in the liver of 10-week-old animals. The Bcl-2/Bad expression area ratio in 10-week-old animals was twice as high as in 18-week-old animals, which indicates the presence of conditions for blocking apoptosis in the liver of younger db/db mice. At the 18th week of life, db/db mice displayed an almost threefold increase in the expression area of the Bad protein against the background of an unchanged expression of the Bcl-2 protein. The decrease in the Bcl-2/Bad staining area ratio in 18-week-old animals was due to the increase in the Bad expression area, which indicates the absence of antiapoptotic cell protection and creates conditions for activation of the mitochondrial pathway of apoptosis in the liver of male db/db mice with pronounced signs of obesity and DM2

Accelerated Recovery Protocol in Extended Combined and Single-Stage Surgery for Pelvic Cancer

Introduction. The study aimed to evaluate a routine accelerated recovery management in patients with extended combined pelvic surgery.Materials and methods. We surveyed the records and outcomes in various oncological patients following the accelerated recovery protocol after a routine extended combined pelvic surgery at the Moscow City Oncology Hospital No. 1 during 2018–2020.Results and discussion. Locally advanced tumours comprised 37 (75.5 %) cases, and the remaining 12 (24.5 %) were nonpelvic resections due to metastasis. Radical surgery was achieved in 41 (83.7 %) cases, while the other 8 (16.3 %) were symptomatic due to the emerged complications of intestinal permeability disruption, bleeding, urinary obstruction, paracancrotic abscess, internal fistulae or pain syndrome. Postoperative complications were evaluated in the Clavien-Dindo classification.Conclusion. The results obtained suggest the feasibility of an accelerated recovery protocol-based practice in extended combined pelvic surgery
