Histological examination of biopsy material of animal bone tissue using osteoplastic biocomposite coating of implants accelerating consolidation

In modern veterinary and humane medicine, the issue of optimizing reparative osteogenesis, aimed at accelerating consolidation, preventing bacterial infection, a stabilization method, as well as activating osteoinductive and osteoconductive properties, is quite acute. This can be achieved using osteoplastic biocomposite coatings on implants. The significant role of such components as hydroxyapatite, methyluracil, amoxicillin in metabolic processes aimed at regenerative, antibacterial and metabolic processes of osteogenesis has been determined. The group of authors set the goal of the study: to study, using a histological method, the quantitative and qualitative aspects of fusion of a fracture of the middle third of the diaphysis of long tubular bones (radius), in an experiment, using the developed biocomposite coating. The material for this study was histotopographic preparations of bone regenerates obtained on day 35 using a needle for trephine biopsy of bone tissue, after consolidation of the simulated fracture was established using implants with the developed osteoplastic coating. As a result of the study of histotopographic materials using 3.5% and 5% biocomposite coating to accelerate consolidation, in the experimental groups there is no amount of the developed composite, which indicates biocompatibility with complete biointegration without allergenic and cytostatic effects.Throughout the experiment, no significant difference was found between the experimental groups; in each group, restored microcirculation was visualized with many physiological Haversian canals with blood vessels, the nervous system and adequate tissue trophism. Histological examination of the formed bone regenerate is necessary to confirm the completed accelerated process of osteogenesis in small non-productive animals.

Формирование исполнительных функций в дошкольном возрасте

Executive functions (EF) are responsible for creative thinking, shifts in perspectives, and accepting the views of others. EF allow us to take a break and think before we do something or give an inappropriate answer, to resist temptations and to focus on the current task. EF is a general term for cognitive processes which regulate, control and manage other cognitive processes necessary for behavior change. The main executive functions include: inhibition (inhibition of reaction, self-control, resistance to temptations and resistance to act impulsively), interference control (selective attention and cognitive inhibition), working memory, mental set-shifting (including thinking “out of the box”, which allows us to see things from different perspectives, adapting quickly and flexibly to changing circumstances). The paper provides an overview of Russian and international research on EF. It analyses the possibility of training and developing EF in preschoolers. The level of EF development is regarded as a predictor of academic performance in school. The paper explores the results of modern international empirical research on the relationship of EF and the development of theory of mind and manifestation of aggressive behavior. The study has revealed that EF deficit is a predictor of high aggression levels. The paper focuses on the role of such components of EF as working memory, inhibition, mental set-shifting, and attention in different types of aggressive behavior. The paper presents data on gender dependence of EF deficit and various types of demonstrated aggressiveness. It also provides data on the relationship between EF and the development of theory of mind. The data highlights the role of mental set-shifting in the development of children’s ability to understand the mental state of another person. Besides, the paper provides data from international studies on the role of game behavior therapy in the development of various components of EF.

Emotional Intelligence, Emotional Self-regulation and Dispositional Mindfulness in High School Intelligent Students

The aim of current investigation was to study the relationship among emotional intelligence, mindfulness and emotional self-regulation in high school intelligent students. in line with the objectives of the study, using sectional method 144 intelligent students (77male and 67 female) of intelligent schools were selected in random sampling method. They were asked to fill Bar-On EQ-i , FFMQ, and Self-Regulation Questionnaire (SRQ) Data were analyzed using chi square, t-test, and Pearson’s moment correlation and multivariate regression statistical tests. chi square tests revealed that the two studied male and female intelligent students have no significant difference in the demographic variables. Moreover results of the t-test indicated that the two groups have significant difference in emotional intelligence. Results of stepwise regression indicated that variables of acting with awareness and no reaction from mindfulness variable explains about 17% of emotional self-regulation variance. Moreover, the components of problem solution and optimism about emotional intelligence explain 38% of emotional self-regulation. According to the results, it can be concluded that from components of mindfulness, acting with awareness and no mental reaction and from components of emotional intelligence, problem solution and optimism play a major role in emotional self-regulation of the intelligent students. Hence it seems necessary to pay much attention to the role of such components in emotional self-regulation and decreasing negative emotions of such students.

The impact of Polycomb group (PcG) and Trithorax group (TrxG) epigenetic factors in plant plasticity.

Current advances indicate that epigenetic mechanisms play important roles in the regulatory networks involved in plant developmental responses to environmental conditions. Hence, understanding the role of such components becomes crucial to understanding the mechanisms underlying the plasticity and variability of plant traits, and thus the ecology and evolution of plant development. We now know that important components of phenotypic variation may result from heritable and reversible epigenetic mechanisms without genetic alterations. The epigenetic factors Polycomb group (PcG) and Trithorax group (TrxG) are involved in developmental processes that respond to environmental signals, playing important roles in plant plasticity. In this review, we discuss current knowledge of TrxG and PcG functions in different developmental processes in response to internal and environmental cues and we also integrate the emerging evidence concerning their function in plant plasticity. Many such plastic responses rely on meristematic cell behavior, including stem cell niche maintenance, cellular reprogramming, flowering and dormancy as well as stress memory. This information will help to determine how to integrate the role of epigenetic regulation into models of gene regulatory networks, which have mostly included transcriptional interactions underlying various aspects of plant development and its plastic response to environmental conditions.

Post-Liberalization Challenges in Telecommunications: Balancing Antitrust and Sector-Specific Regulation; Tentative Lessons from the Experiences of the United States, New Zealand, Chile, and Australia

This paper seeks to shed some light both on how economy-wide and infrastructure or sector-specific components of the regulatory framework should be designed and on what the respective roles of such components should be to maximize the efficiency of economic regulation in telecommunications. It attempts to derive some lessons from the experience of four countries - the United States, New Zealand, Chile, and Australia - which have chosen to put different emphasis and given different roles to those different elements of the regulatory framework. Each of the four country model is evaluated on its ability to achieve key objectives of telecommunications regulation, which are presented in the following section. Then, the paper compares the experiences of the four countries in order to draw lessons on how economy-wide and infrastructure or sector-specific rules and institutions should de designed to ensure the maximum efficiency of the regulatory framework applicable to telecommunications.

Ultrastructure of the endoplasmic factor responsible for cytoplasmic streaming in Chara internodal cells.

Previous investigators have proposed that cytoplasmic streaming in Chara internodal cells results from the interaction between an endoplasmic factor and fibrils composed of microfilaments in the stationary cortex. Using the internal perfusion technique, we confirmed the observation that organelles which had been attached to the fibrils by decreasing the internal concentration of ATP moved along the fibrils after ATP was introduced. Thin-sectioned specimens revealed that endoplasmic organelles of various shapes were linked to microfilament bundles in the absence of ATP. Linkage was effected by regularly arranged electron-dense materials with a spacing of 100 -- 130 nm at definite regions on each organelle. The organelles in question were studied in negatively stained preparations of endoplasm. The organelles had some common features. (1) They were all membrane-limited.(2) Their sizes and configurations varied largely. (3) One or more protuberances were present on them. (4) The protuberances were usually rod- or horn-like. (5) Small globular bodies 20--30 nm in diameter were found in ordered array with the same spacing as those in thin sections at the surface of the protuberances. (6) Many fine filaments were always attached to the surface of the protuberances. These fine filaments differed from F-actin in diameter (less than 4 nm) and inability to react with heavy meromyosin from rabbit skeletal muscle. The role of such components of the organelles in cytoplasmic streaming is discussed. A paracrystalline array of microfilaments with a transverse periodicity of about 38 nm is presented, together with its optical diffraction pattern.
