Possibilities for a Positive Change in the Body Image of Students in Dance-Motor Training

This article presents a study on the effectiveness evaluation of the author’s program of dance-motor training aimed at developing a positive image of the physical self in adolescence. The authors used a comprehensive approach to assess the effectiveness of training: the types of psychological problems, the characteristics of the image of the physical self, and the functional state of the participants in the training were monitored. The study involved 96 students from Nizhny Novgorod universities aging from 18 to 25. The researchers used the methods of the drawing test ‘Human figure’ (K. Mahover, F. Gudinaf); the test of twenty statements ‘Who Am I’ (M. Kun, T. McPartland); and the method of computer campimetry for assessing the functionalstate of the body by the function of color-diffusion (SA Polevaya). The self-body image of the subjects in the experiment was characterized by weak integration and awareness; negative and disharmonious deep self-esteem; low values of awareness of one’s own uniqueness; and the maximum limit of the green color was detected in more than half of the subjects (61.45%). Dance-motor training was based on themethodological principles of the integrative-holistic and syndrome-factor approach to mental disorders, developed by A.R. Luria. The development of the psychomotor sphere of a personality was considered as a trigger mechanism for restoring the interaction between the psychological and physiological sub-systems of mental activity. The dependence of the content and structure of mental processes on sociocultural experience (i.e., world artistic culture) was actualized. The mechanism of the regulating role of an image and speech in building the movement has become more active. Dance-motor trainings with students were conducted over the course of a year. We used methods of body-oriented psychotherapy, vegetotherapy, and dance-motor therapy, including contact improvisation. The dance-motor training included warm-ups (aerobic and anaerobic exercises, muscle-stretching exercises); the thematic study of muscle clamps; and choreographic performances (learning movement stereotypes, free and contact improvisation). In the control experiment, a statistically significant conjugate dynamics was observed for the majority of the studied parameters (0.001). Keywords: body image, dance-motor training, student

The effect on nitrogen oxide emission from agricultural soils

The study investigates the effect of biochar on nitrous oxide emission in Endoargic Anthrosols in the southern territory of the Russian Far East. Biochar (bio-charcoal) was applied in the amounts of 1 kg/m2 and 3 kg/m2 in combination with organic and mineral fertilizers to drained and drain-free fields during the vegetation season, and the five-gas analyzer G2508 (Picarro) was used. Cumulative flows of N2O were estimated. The analysis revealed that biochar reduces the emissions and the cumulative flow of nitrous oxide. The higher the dose of biochar, the lower the emission and cumulative flows of nitrous oxide, regardless of a drainage system. Biochar (1 kg/m2) reduced the cumulative N2O flow from the soil by 52.2% throughout the experiment conducted, while a dose of 3 kg/m2 allowed for 97.8% reduction. The study found that organic and mineral fertilizers can be effectively used in combination with biochar, as N2O emission from the soil with mineral fertilizers is significantly higher than from the soil with organic fertilizers. Biochar (1 kg/m2) combined with organic fertilizers reduces N2O emission by 53.7%, while a dose of 3 kg/m2 can reduce emissions by 88.9%. Biochar (1 kg/m2) combined with mineral fertilizers reduced the flow of N2O by 17.5%, while a 3 kg/m2 dose of biochar used with mineral fertilizers reduced the emission by 85.3%

Development of a microchip analytical system with PCR reagents lyophilized into aluminum microchips and modified by the plasma enhanced chemical vapor deposition

Микрочиповые аналитические системы для молекулярно-генетического анализа в последние годы привлекают повышенный интерес исследователей. Алюминиевые микрочипы являются особенно перспективными для внедрения микрочипового формата полимеразной цепной реакции (ПЦР) в лабораторную практику. Подобные микрочипы требуют пассивации поверхности для предотвращения ингибирования ПЦР и улучшения аналитических характеристик системы. Привлекательна и возможность снижения трудозатрат и ошибок оператора за счет лиофилизации реактивов в микрочипах. Микрочипы с лиофилизированными реактивами позволяют избежать сложностей, связанных с хранением при низкой температуре, сокращают количество стадий пипетирования и тем самым уменьшают риск ложноположительных результатов, которые могут быть вызваны контаминацией проб. В работе предложен метод иммобилизации реагентов для ПЦР в микрореакторах алюминиевых микрочипов, поверхность которых была предварительно пассивирована с помощью плазмохимического осаждения из газовой фазы (ПХО). В качестве модельных объектов для лиофилизации выбраны тест-системы для определения фрагмента гена 35S вируса мозаики цветной капусты, используемого в генетически-модифицированных организмах (ГМО), фрагмента геномной ДНК микроорганизма Mycoplasma hominis, а также фрагмента гена глобина человека (белковая часть гемоглобина человека). Разработана экспериментальная установка для лиофилизации, которая позволила оптимизировать условия проведения процесса. Показано, что полученные таким образом алюминиевые микрочипы могут храниться не менее двух месяцев при комнатной температуре, и их аналитические характеристики сравнимы с ПЦР с использованием жидких реактивов, при в 20 раз меньшем потреблении реактивов и в 2-3 раза меньшем количестве операции пипетирования.Microchip analytical systems for the polymerase chain reaction (PCR) have attracted an increased interest of researchers in recent years. Aluminum microchips are particularly promising for the microchip PCR techniques implementation in a routine laboratory practice. However, the surface of the chips needs to be chemically inert for the PCR inhibition prevention and improved analytical characteristics of the system. It should also be noted that the possibility of decreasing of handling procedures and operator mistakes by using lyophilized reagents inside microreactor remains very attractive. Such microchip systems allow avoiding some of the storage difficulties and significantly decrease the number of pipetting stages. All of these lead to minimizing the risk of false positive results due to the sample cross-contamination. In this paper a method of PCR reagents lyophilization into the microreactors of aluminum microchips was developed. The surface of the microchip was modified using the Plasma Enhanced Chemical Vapor Deposition (PE CVD). As the model reagents for the lyophilization, the PCR test systems for 35S gene fragment determination (cauliflower mosaic virus) and human globin (protein part of human GEM) were used. The newly developed experimental system for lyophilization allowed optimizing the process for several microchips. It was shown that the obtained aluminum microchip could be stored under the ambient conditions up to 5 months and their analytical characteristics are comparable with the test-tube PCR, with 20 times less the reagents consumption and 2-3 times less the number of pipetting steps

Antibiofilm activity of aminopropanol derivatives against Pseudomonas aeruginosa

Bacterial biofilm, particularly formed by Pseudomonas aeruginosa, are a cause of severe chronic infectious diseases. Bacteria within a biofilm are phenotypically more resistant to antibiotics and the macroorganism immune system, making it an important virulence factor for many microbes. The aminopropanol derivatives with adamantyl (KVM-97) and N-alkylaryl radicals (KVM-194, KVM-204, KVM-261, and KVM-262) were used as study object. The aim of this study was to investigate the antibiofilm activity of compounds on biofilm formation and on mature biofilm of P. aeruginosa. The effects of the aminopropanol derivatives on the biofilm mass were evaluated by using crystal violet assay. Ciprofloxacin, meropenem, ceftazidime, gentamicin were used as reference substances. Reported results demonstrate that all compounds displayed antibiofilm activity at the tested concentrations. Remarkable reduction in biofilm formation of P. aeruginosa was found after treatment with KVM-97, KVM-261 and KVM-262 in high concentration (5× MIC), biofilm inhibition activity were 84.3%, 90.5% and 83.3% respectively. After a treatment with KVM-204 at 250 μg/ml (5× MIC) 76.6% of the preformed 24-hr biofilms were destroyed. Furthermore, compounds KVM-97, KVM-194, and KVM-261 in both concentrations showed potent antibiofilm activity against the P. aeruginosa, inhibition activity values being between 56.7 and 65.7%. All tested compounds in dose-dependent manner exhibited pronounced inhibition activity against mature 5-days P. аeruginosa biofilm. It was also observed that tested compounds show high antibiofilm activity in comparison to reference antimicrobials. The aminopropanol derivatives may provide templates for a new group of antimicrobial agents and potential future therapeutics for treating chronic infections
