Regional development and banking activities

This article is a continuation of studies devoted to the interaction of the region and its banking system. The research object in this article is the banking system of the Rostov region, the Southern Federal District, and its impact on the acceleration of socioeconomic development of both the regions. The subject of the study is interaction of banks with the real sector of the economy and the population of the region. The authors analyzed the scientific sources exploring the interaction of the banking and real sectors of the economy and methodological approaches to the analysis of banking activities’s effects on the region and its socio-economic indicators. Based on econometric modeling, quantitative and qualitative regularities of the indicators are revealed. As a result, authors concluded that the growth in the total volume of profits received by existing credit institutions contributes to the growth of such important socio-economic indicators like Gross Regional Product, internal costs of research and development, labor productivity, fixed asset investments, per capita income, growth of deposits attracted by credit institutions, as well as the growth in the amount of debt on loans extended by credit institutions to legal entities and individuals.peer-reviewe

The effect of laser radiation on the surface of the aluminum alloy AMG-6

The effect of laser radiation on the change in the amount of oxygen and its distribution on the surface of an aluminum alloy AMG-6 is studied. It has been established that the oxygen content increases with time after laser treatment. The latter worsens the wetting of the alloy.Исследовано влияние лазерного излучения на изменение количества кислорода и его распределения на поверхности алюминиевого сплава АМГ-6. Установлено, что со временем после лазерной обработки содержание кислорода увеличивается. Последнее ухудшает смачивание сплава

Pharmacological preconditioning by incretinomimetics exenatide and vildagliptin: decrement of liver ischemia-reperfusion injury

Study of hepatoprotective activity of exenatide and vildagliptin on the liver ischemia/reperfusion model, taking into account biochemical and morphological parameter

Dynamic Wetting and Dewetting: Comparison of Experiment with Theories

The dynamics wetting/dewetting of a metal surface by distilled water drop was studied experimentally. The advancing and receding dynamic contact angles were obtained as a function of a contact line speed. The hydrodynamic and molecular-kinetic models have been applied to the experimental data to interpret the obtained results. The independent variables of the molecular-kinetic and hydrodynamic models, and the determination coefficient were determined by fitting procedure. The receding contact angles are found to be fitted better to the wetting models in comparison with the advancing dynamic contact angles

Evaporation Rate of a Liquid Layer Streamlined by Gas Flow in Minichannel

Paper presents the experimental results of mass evaporation rate from ethanol layer surface into a moving in parallel way air flow. Dependences of the mass evaporation rate on the gas velocity, temperature difference between gas and liquid layer, and liquid layer thickness were obtained. The assumption about the formation of the concentration boundary layer at the interface was made. It is found that with increasing the gas flow velocity the gradient of vapor concentration in the gas phase increases; as a result the evaporation rate rises. When changing the liquid layer thickness, the local maximum of evaporation rate was observed, but for 2 mm thickness layer two maxima were found. Probably, it is due the appearance of unstable structures on the liquid surface

Forced spreading over superhydrophobic and copper surfaces

Dynamic spreading over superhydrophobic and copper surfaces was studied experimentally under the condition of contact line movement with speed greater than 1 mm/sec. Three modes of spreading of distilled water drop over copper surfaces with sufficient typical roughness (0.591, 5.190 and 6.210 μM) were detected. The first one is drop formation when the contact line speed and dynamic contact angle increase sharply. The second mode is spreading of a drop, which is characterized by a monotonic decrease in the contact line speed and dynamic contact angle. The third one is a formation of an equilibrium contact angle at a constant wetted area (the contact line speed tends to zero, and spreading of a drop occurs as long as the driving force is greater than zero). Some features in spreading were detected on superhydrophobic surface with parameter roughness of 0.751μm compared to other substrates. During drop formation after sharp increase in the contact line speed and dynamic contact angle, there is a mode which is accompanied by a decrease in the contact line speed and monotonic increase in the advancing dynamic contact angle

Characteristics of blood pressure level in children with different body weight

BACKGROUND: Essential arterial hypertension (AH) develops more often in children with accompanying risk factors — obesity, overweight, positive heredity and genetic predisposition.AIM: Study of peculiarities of arterial hypertension clinical course in adolescents with normal body weight, overweight and obesity.MATERIALS AND METHODS: The study was conducted on children with arterial hypertension who received treatment in two hospitals in Voronezh in 2016–2020. A retrospective analysis of the children’s case histories was carried out taking into account the anamnesis, clinical laboratory and instrumental examination data and the pharmacotherapy. Some children underwent polymerase chain reaction genetic testing to determine pathological alleles of genes regulating blood pressure (BP).RESULTS: 96 patients aged 9 to 17 took part in the study. The group with normal body weight included 38 children (39.6%), median age 16.4 (aged 10.7; 17.9), with overweight — 33 people (34.4%), median age 15.2 (aged 12.0; 17.9), with obesity — 25 children (26.0%), median age 14.5 (aged 9.2; 17.9). Obese children developed arterial hypertension at earlier age (p = 0.023). According to blood pressure daily monitoring (BPDM), pathological values of systolic blood pressure (SBP) during the day (above the 95th percentile) among children with normal body weight were observed in 17 patients (44.7%), with excess body weight — in 14 people (42.4%), with obesity — in 16 people (64%), p = 0.031. Accurate difference values between the groups were obtained in terms of time index (TI) of SBP at night (p = 0.006). Time index of diastolic BP during the day > 50% was observed only in the obese children group — 4 people (16%) (p = 0.042). Pathological alleles of the angiotensinogen gene (AGT: 704 T>C), aldosterone synthase gene (CYP11B2: -344 C>T) and endothelial nitrogen synthase type 3 (NOS3: -786 T> C) were identified most frequently during genetic testing in some patients.CONCLUSION: Children with obesity developed earlier arterial hypertension compared to the same-age children with normal body weight and more often had unfavorable type of arterial hypertension according to BPDM. These results can be used to choose individual therapy and to develop special attention as regards certain target organs damage

Репарация легочной ткани при впервые выявленном туберкулезе легких как генетически детерминированный процесс

The objective of the study is to assess the effect of rs6707530 polymorphism of the FN1 gene and rs1150754 polymorphism of the TNXB gene on the healing of lung tissue destruction in patients with newly detected pulmonary tuberculosis.Subjects and methods. 82 patients older 18 years with newly diagnosed pulmonary tuberculosis with destruction were enrolled in the study. X-ray data were assessed on the 2nd, 4th and 6th months of the study. Patients were divided into 2 groups depending on the efficacy of chemotherapy intensive phase.Results. In the group of patients with an effective course of chemotherapy, the frequency of carriers of G allele (p < 0.001) and T/G genotype (p = 0.01) in rs6707530 locus of the FN1 gene was higher. While T/T genotype (p = 0.002) and T allele (p < 0.001) prevailed among the patients with persisting destruction of lung tissue after the intensive phase of chemotherapy.Цель исследования: оценить влияние полиморфизма rs6707530 гена FN1 и полиморфизма rs1150754 гена TNXB на динамику заживления деструкции легочной ткани у больных с впервые выявленным туберкулезом легких.Материалы и методы. В исследование включено 82 пациента старше 18 лет с впервые выявленным туберкулезом легких в фазе распада. На 2, 4 и 6-м мес. исследования проводилась оценка рентгенологических данных. Пациенты были разделены на 2 группы в зависимости от эффективности интенсивной фазы химиотерапии.Результаты. В группе пациентов с эффективным курсом химиотерапии чаще встречались носители аллеля G (p < 0,001) и генотипа T/G (p = 0,01) в локусе rs6707530 гена FN1. При этом генотип T/T (p = 0,002) и аллель Т (p < 0,001) доминировали среди пациентов с сохранением деструкции легочной ткани после интенсивной фазы химиотерапии

Пищевой статус и структура потребления макронутриентов у больных туберкулезом с различной лекарственной устойчивостью возбудителя

The objective: to assess the nutritional status and actual nutrition of respiratory tuberculosis patients with various drug resistance patterns.Subjects and methods. The actual nutrition of tuberculosis patients was assessed using a standard questionnaire containing questions about the amount of food and meals consumed at home in the last 30 days preceding the survey. Assessment of anthropometric indicators and the survey were carried out by medical workers when the patients were admitted to hospital. Patients were enrolled from April to August 2018 out of 300 respiratory tuberculosis patients who had a positive result of a sputum test for M. tuberculosis. The multidrug resistant tuberculosis group consisted of 222 patients, while the group of those drug susceptible or having mono- or polyresistance included 78 patients.Results. It was found out that the home diet of patients with active respiratory tuberculosis was imbalanced in respect of basic nutrients and energy. The following was detected: lack of protein in the diet (including the one of animal origin) in 80.6 ± 2.3% with a depth of more than 55.7%; excess unbalanced fat consumption in 66.6 ± 2.7%; insufficient consumption of dietary fiber in 45.0 ± 2.8%. Multidrug resistant tuberculosis patients consumed more energy and macronutrients (proteins, fats, dietary fiber, animal protein, cholesterol, and fatty acids) both in absolute terms and relative to individual needs, but at the same time they had worse nutritional status indicators; 37,2% of them had malnutrition of the 1st to 3rd degree. At the same time, patients with multidrug resistant tuberculosis were significantly more often HIV-positive, they had disseminated and chronic tuberculosis, the treatment of which itself lead to a decrease in appetite, malnutrition, metabolic and digestion disorders.Цель исследования: оценка пищевого статуса и фактического питания больных туберкулезом органов дыхания с различной лекарственной устойчивостью возбудителя.Материалы и методы. Оценка фактического питания больных туберкулезом проводилась с использованием стандартного опросника, содержащего вопросы, характеризующие количество потребляемых пищевых продуктов и блюд в домашних условиях в течение последних 30 дней, предшествовавших опросу. Определение антропометрических показателей и опрос проводили медицинские работники в момент поступления пациентов в стационар. Выборка пациентов сформирована в период с апреля по август 2018 г. из 300 больных туберкулезом органов дыхания, выделявших M. tuberculosis. Группу туберкулеза с множественной лекарственной устойчивостью составили 222 больных, группу с сохраненной чувствительностью M. tuberculosis к противотуберкулезным препаратам, а также с моно/полирезистентностью ‒ 78 пациентов.Результаты. Установлено, что домашнее питание больных активным туберкулезом органов дыхания характеризовалось несбалансированностью основных пищевых веществ и энергии. Выявлены: недостаток белка в рационе (в том числе животного происхождения) ‒ у 80,6 ± 2,3% с глубиной более 55,7%; избыточное несбалансированное потребление жиров ‒ у 66,6 ± 2,7%; недостаточное потребление пищевых волокон ‒ у 45,0 ± 2,8%. Больные туберкулезом с множественной лекарственной устойчивостью потребляли больше энергии и макронутриентов (белков, жиров, пищевых волокон, животного белка, холестерина, жирных кислот) как в абсолютном выражении, так и относительно индивидуальной потребности, но вместе с тем имели худшие показатели пищевого статуса, 37,2% лиц имели недостаточность питания 1-3-й степени. При этом больные туберкулезом с множественной лекарственной устойчивостью значимо чаще имели ВИЧ-положительный статус, распространенный и хронический туберкулез, лечение которого само приводит к снижению аппетита, недоеданию, нарушению обмена и усвоения пищевых веществ.Авторы заявляют об отсутствии у них конфликта интересов
