ПРЕСТУПНОСТЬ НЕСОВЕРШЕННОЛЕТНИХ: ОСНОВНЫЕ ТЕНДЕНЦИИ (РЕГИОНАЛЬНЫЙ АСПЕКТ)

he article analyzes the nature and internal structure of various types of crimes in which involved minors. Describes the main social factors contributing to this anomaly in the period of development of society. Investigated the motivation, the system and the types of crimes of minors in the Volgograd region, are the main trends of development of this phenomenon. The study also discusses the theoretical basis of the problem of the influence of economic stability on the species structure of juvenile delinquency. In this study the analysis of various types of deviance minors in different areas of the city of Volgograd. In the process of rapid modernization of communication processes most of today’s youth have not been able to quickly rebuild their behavior. Currently, the value-perception of the adolescents focused on the material benefits in terms of expanded economic interactions. In these conditions, social processes become increasingly removed from humane and spiritual orientations. The effective functioning of society in its interaction based on cooperation and understanding is of great importance to stimulate the positive trends in social sphere in modern Russia. The modern period of development, coupled with a drastic breaking of the foundations of life, the formation of new social relations and institutions and the destruction of the old, inevitably contributes to social tension, the reassessment of social and moral values and development of deviant behavior of minors. The advantages of this study are the involvement of local archives regional committees on Affairs of minors, was first introduced to active scientific revolution, as well as logical structuring and grouping of the main issues related to the dynamics and changes in the species structure of juvenile crime, which allowed us to perform a fairly extensive archive of statistical material. Based on this analysis, the authors made a “psychological portrait” of a juvenile offender, identified the main motives that caused teenagers to commit various crimes, considered in detail the structure of their crimes. The problem of motivation has received considerable attention, as its study brings researchers to the subjective knowledge of the motor components, causing a minor to commit a crime. It is equally important that, given the socio-economic factors in the analysis of human aggression is of great value not only for theoretical analysis through a systemic approach, but also for further improvement of preventive, rehabilitative work with young offenders. The process of modernization of the Russian society have not only brought much positive change, but destroying the traditional way of life, have brought cardinal changes in communication processes of the younger generation. Overall, the article gives some increase of knowledge in the identified scientific fields, contributes to the development of the science and practice of studying of illegal behaviour of minors and promotes the understanding of problems related to social processes in modern society. Having carefully studied the main factors that intensify illegal behavior of adolescents in the period of economic transformation of society, the authors come to the conclusion that the processes of industrialization, urbanization, changing economic structure has had on the structure and activity of deviant behavior of teenagers in the period under review, a significant impact. This is probably due to the fact that these processes at the initial stage of its development has resulted in significant changes in the internal foundations of the structure of society.В представленной статье проанализированы природа и внутренняя структура различных  видов преступлений, в которых принимали участие несовершеннолетние. Описаны  основные социальные факторы, способствующие развитию данной аномалии в  рассматриваемый период развития общества. Исследованы мотивация, система и виды  преступлений несовершеннолетних в Волгоградском регионе, представлены основные тенденции развития данного явления. Также в исследовании рассматриваются  теоретические основы проблемы влияния экономической стабильности на видовую  структуру правонарушений несовершеннолетних. В исследовании предпринят анализ  различных видов девиаций несовершеннолетних в различных районах города Волгограда. В процессе ускоренной модернизации коммуникационных процессов большинство  современной молодежи оказалось не в состоянии в короткие сроки перестроить свое поведение. В настоящее время ценностное восприятие подростков ориентировано на  материальные блага в условиях расширения экономических форм взаимодействия. В этих  условиях социальные процессы становятся все более отстраненными от гуманных и духовных ориентаций. Эффективное функционирование общества в его взаимодействии,  основанном на сотрудничестве и понимании, имеет большое значение для стимулирования  положительных тенденций в социальной сфере современной России. Современный период  развития, сопряженный с кардинальной ломкой устоев жизни, образованием новых  общественных отношений и институтов и разрушением старых, неизбежно способствует  росту социальной напряженности, переоценке социально-нравственных ориентиров и развитию девиантного поведения несовершеннолетних. Преимуществами данного  исследования являются привлечение материалов местных архивов районных комитетов по делам несовершеннолетних, впервые вводящихся в активный научный оборот, а также  логическая структурированность и группировка основных вопросов, связанных с динамикой  и изменением видовой структуры правонарушений несовершеннолетних, которые позволили проанализировать довольно обширный архивный статистический материал. На основе этого  анализа авторы составили “психологический портрет” несовершеннолетнего  правонарушителя, определили основные мотивы, побуждавшие подростков к совершению различных преступлений, подробно рассмотрели структуру совершенных ими преступлений. Проблеме мотивации уделяется значительное внимание, поскольку ее изучение приближает  исследователей к уяснению субъективно-двигательных компонентов, приводящих  несовершеннолетних к совершению преступления. Не менее важно, что учет социально- экономических факторов при анализе человеческой агрессивности имеет большую ценность  не только для теоретического анализа в рамках системного подхода, но и для дальнейшего  совершенствования профилактической, коррекционной работы с подростками- правонарушителями. Процесс модернизации российского общества принес не только много  позитивных перемен, но, разрушая традиционный уклад жизни, привнес кардинальные  изменения в коммуникационные процессы подрастающего поколения. В целом статья дает свой прирост знаний в обозначенной научной области, вносит свой вклад в развитие науки  и практики изучения противоправного поведения несовершеннолетних и способствует  осмыслению проблем, связанных с социальными процессами, происходящими в современном обществе. Внимательно изучив основные факторы, активизирующие противоправное поведение подростков в период экономической трансформации общества,  авторы приходят к выводу о том, что процессы индустриализации, урбанизации, изменения  экономического уклада оказали на структуру и активность девиантного поведения  подростков в рассматриваемый период значительное влияние. Вероятно, это связано с тем,  что данные процессы на начальной стадии своего развития привели к существенному изменению внутренних устоев структуры общества

Scientific, institutional and personal rivalries among Soviet geographers in the late Stalin era

Scientific, institutional and personal rivalries between three key centres of geographical research and scholarship (the Academy of Sciences Institute of Geography and the Faculties of Geography at Moscow and Leningrad State Universities) are surveyed for the period from 1945 to the early 1950s. It is argued that the debates and rivalries between members of the three institutions appear to have been motivated by a variety of scientific, ideological, institutional and personal factors, but that genuine scientific disagreements were at least as important as political and ideological factors in influencing the course of the debates and in determining their final outcome

Deactivation and Regeneration of Mo/ZSM-5 Catalysts for Methane Dehydroaromatization

The methane dehydroaromatization (DHA) was studied over a series of impregnated Mo/ZSM-5 catalysts with different molybdenum contents (1-10 wt.%). It was shown that total methane conversion was decreased by 30% during 12 h of DHA reaction. The benzene formation rate was increased from 0.5 to 13.9 mol C6H6/(gMo·s) when the molybdenum content in the catalyst was lowered from 10 to 1 wt.%. The deactivated Mo/ZSM-5 catalysts were studied by a group of methods: N2 adsorption, XRD, TGDTA, HRTEM and XPS. The content and condensation degree (C/H ratio) of the carbonaceous deposits was found to increase with an increase of either of the following parameters: molybdenum content (1-10 wt.%), reaction temperature (720-780 °C), space velocity (405-1620 h-1), reaction time (0.5-20 h). The stability of Mo/ZSM-5 catalysts in reaction-regeneration cycles was better when the time on stream was shorter. The regeneration conditions of deactivated Mo/ZSM-5 catalysts providing their stable operation under multiple reaction-regeneration cycles have been selected

Clonal Hematopoiesis and Risk of Atherosclerotic Cardiovascular Disease

BACKGROUND: Clonal hematopoiesis of indeterminate potential (CHIP), which is defined as the presence of an expanded somatic blood-cell clone in persons without other hematologic abnormalities, is common among older persons and is associated with an increased risk of hematologic cancer. We previously found preliminary evidence for an association between CHIP and atherosclerotic cardiovascular disease, but the nature of this association was unclear. METHODS: We used whole-exome sequencing to detect the presence of CHIP in peripheral-blood cells and associated such presence with coronary heart disease using samples from four case-control studies that together enrolled 4726 participants with coronary heart disease and 3529 controls. To assess causality, we perturbed the function of Tet2, the second most commonly mutated gene linked to clonal hematopoiesis, in the hematopoietic cells of atherosclerosis-prone mice. RESULTS: In nested case-control analyses from two prospective cohorts, carriers of CHIP had a risk of coronary heart disease that was 1.9 times as great as in noncarriers (95% confidence interval [CI], 1.4 to 2.7). In two retrospective case-control cohorts for the evaluation of early-onset myocardial infarction, participants with CHIP had a risk of myocardial infarction that was 4.0 times as great as in noncarriers (95% CI, 2.4 to 6.7). Mutations in DNMT3A, TET2, ASXL1, and JAK2 were each individually associated with coronary heart disease. CHIP carriers with these mutations also had increased coronary-artery calcification, a marker of coronary atherosclerosis burden. Hypercholesterolemia-prone mice that were engrafted with bone marrow obtained from homozygous or heterozygous Tet2 knockout mice had larger atherosclerotic lesions in the aortic root and aorta than did mice that had received control bone marrow. Analyses of macrophages from Tet2 knockout mice showed elevated expression of several chemokine and cytokine genes that contribute to atherosclerosis. CONCLUSIONS: The presence of CHIP in peripheral-blood cells was associated with nearly a doubling in the risk of coronary heart disease in humans and with accelerated atherosclerosis in mice.

Cathepsin S Deficiency Results in Abnormal Accumulation of Autophagosomes in Macrophages and Enhances Ang II–Induced Cardiac Inflammation

BACKGROUND: Cathepsin S (Cat S) is overexpressed in human atherosclerotic and aneurysmal tissues and may contributes to degradation of extracellular matrix, especially elastin, in inflammatory diseases. We aimed to define the role of Cat S in cardiac inflammation and fibrosis induced by angiotensin II (Ang II) in mice. METHODS AND RESULTS: Cat S-knockout (Cat S(-/-)) and littermate wild-type (WT) C57BL/6J mice were infused continuously with Ang II (750 ng/kg/min) or saline for 7 days. Cat S(-/-) mice showed severe cardiac fibrosis, including elevated expression of collagen I and α-smooth muscle actin (α-SMA), as compared with WT mice. Moreover, macrophage infiltration and expression of inflammatory cytokines (tumor necrosis factor α, transforming growth factor β and interleukin 1β) were significantly greater in Cat S(-/-) than WT hearts. These Ang II-induced effects in Cat S(-/-) mouse hearts was associated with abnormal accumulation of autophagosomes and reduced clearance of damaged mitochondria, which led to increased levels of reactive oxygen species (ROS) and activation of nuclear factor-kappa B (NF-κB) in macrophages. CONCLUSION: Cat S in lysosomes is essential for mitophagy processing in macrophages, deficiency in Cat S can increase damaged mitochondria and elevate ROS levels and NF-κB activity in hypertensive mice, so it regulates cardiac inflammation and fibrosis

Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases

The production of peroxide and superoxide is an inevitable consequence of aerobic metabolism, and while these particular "reactive oxygen species" (ROSs) can exhibit a number of biological effects, they are not of themselves excessively reactive and thus they are not especially damaging at physiological concentrations. However, their reactions with poorly liganded iron species can lead to the catalytic production of the very reactive and dangerous hydroxyl radical, which is exceptionally damaging, and a major cause of chronic inflammation. We review the considerable and wide-ranging evidence for the involvement of this combination of (su)peroxide and poorly liganded iron in a large number of physiological and indeed pathological processes and inflammatory disorders, especially those involving the progressive degradation of cellular and organismal performance. These diseases share a great many similarities and thus might be considered to have a common cause (i.e. iron-catalysed free radical and especially hydroxyl radical generation). The studies reviewed include those focused on a series of cardiovascular, metabolic and neurological diseases, where iron can be found at the sites of plaques and lesions, as well as studies showing the significance of iron to aging and longevity. The effective chelation of iron by natural or synthetic ligands is thus of major physiological (and potentially therapeutic) importance. As systems properties, we need to recognise that physiological observables have multiple molecular causes, and studying them in isolation leads to inconsistent patterns of apparent causality when it is the simultaneous combination of multiple factors that is responsible. This explains, for instance, the decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference

ШЕСТИЛЕТНИЙ ОПЫТ ТРАНСПЛАНТАЦИИ СЕРДЦА В ФГБУ «СЕВЕРО-ЗАПАДНЫЙ ФЕДЕРАЛЬНЫЙ МЕДИЦИНСКИЙ ИССЛЕДОВАТЕЛЬСКИЙ ЦЕНТР ИМЕНИ В.А. АЛМАЗОВА»

Aim. To estimate the results of 6-year experience of heart transplantation (HT) in Federal Almazov North-West Medical Research Centre. Methods. From 2010 to 2015 we have performed 65 HT. Mean age was 44.3 ± 14 years old (from 10 to 64 years old). We used biventricular assist device (BIVAD, Berlin Heart Excor) support in 7 heart transplant candidates before HT. 19 patients (29%) received thymoglobulin, whereas 46 patients (71%) had basiliximab to induce immunosuppression.Results. Extracorporeal membrane oxygenation machines were implanted in 5 patients (7.7%) after HT due to acute right ventricular failure. Suture annuloplasty (the Batista procedure) for tricuspid valve repair was carried out in 3 cases (4.6%). Venovenous hemodiafi ltration was used in 11 patients (16.9%). A total of 598 endomyocardial biopsies (EMB) were performed after HT. Evidence of cellular rejection (R1 and R2) was presented in 286 biopsies (48%). The 30-day in-hospital mortality rate was 3.1%. The 6-month survival rate after HT was 92%, 1-year – 91% and overall survival for the 6-year period of observation – 89.2%. Maximum observation period was 71 months.Conclusions. The 6-year experience of HT in our Center has shown a high level of survival. BIVAD Excor support can be effectively used as a «bridge» to HT. Prevention of graft loss due to acute rejection in heart transplant recipients can be achieved only through regular EMB monitoring. The rate of viral infection increased in 2 months after HT.Цель исследования. Оценить результаты трансплантаций сердца (ТС), выполненных в ФГБУ «Северо-Западный федеральный медицинский исследовательский центр имени В.А. Алмазова» за шесть лет.Материалы и методы. В период с 2010-го по 2015 год в Центре было выполнено 65 ТС. Средний возраст реципиентов составил 44,3 ± 14 лет (от 10 до 64 лет). В качестве «моста» к ТС у 7 пациентов перед пересадкой были имплантированы устройства вспомогательного кровообращения (УВК) Excor. Для индукции иммуносупрессивной терапии у 19 пациентов (29%) применялся антитимоцитарный иммуноглобулин, у 46 пациентов (71%) – базиликсимаб.Результаты. У 5 (7,7%) пациентов, в связи с тяжелой правожелудочковой недостаточностью, в раннем периоде после ТС была установлена система ЭКМО. У 3 (4,6%) больных ввиду развития трикуспидальной недостаточности была выполнена пластика трикуспидального клапана по Батиста. Проведение сеансов заместительной почечной терапии после ТС потребовалось у 11 (16,9%) реципиентов. Всего за шестилетний период наблюдения у всех пациентов было выполнено 598 эндомиокардиальных биопсий (ЭМБ). В 286 (48%) случаях диагностировано клеточное отторжение трансплантата стадии R1 или R2. 30-дневная госпитальная летальность составила 3,1% (2 пациента). Выживаемость в отдаленном периоде составила: через 6 месяцев – 92%, через 1 год – 91%, общая выживаемость за 6 лет наблюдения – 89%. Максимальный срок наблюдения – 71 месяц.Заключение. Шестилетний опыт ТС в нашем Центре показал высокий уровень выживаемости после операции. Имплантация УВК является «мостом» к ТС у больных с терминальной стадией ХСН. ЭМБ остается единственным эффективным методом диагностики острого отторжения трансплантата сердца. Через два месяца после ТС в структуре инфекционных осложнений увеличивается частота вирусной инфекции

Interaction of the allogeneic state and hypercholesterolemia in arterial lesion formation in experimental cardiac allografts

To learn more about the interaction of allogeneic transplantation and hypercholesterolemia in the formation of arterial lesions, we performed heterotopic cardiac transplantation in rabbits. We analyzed lesions in both the coronary arteries and the proximal ascending aorta 6 weeks after surgery in both transplanted and native hearts of normocholesterolemic rabbits and those with diet-induced hypercholesterolemia (serum cholesterol, 1638 +/- 366 mg/dL, n = 6, 6 weeks after transplantation). All animals received cyclosporin A (5 mg.kg-1.d-1) for immunosuppression. The transplanted aortas of hypercholesterolemic animals had thicker intimal lesions than did the native aortas (intima/media ratio, 0.67 +/- 0.4 versus 0.08 +/- 0.1, P < .05) and contained more T cells (37.4 +/- 12.8 versus 5.7 +/- 6.2 per high-power field, P < .001). In normocholesterolemic animals (n = 5) the coronary arteries had negligible lesions in the native heart and only slight and inconsistent intimal lesions in the transplanted heart. In the hypercholesterolemic animals, more coronary arteries had intimal lesions in the transplanted hearts than in the native hearts (74% versus 43%). Coronary artery lesions in the native hearts consisted mostly of foam cells, while those in transplanted hearts had more abundant smooth muscle cells as determined by alpha-actin staining. Intimal endothelial cells in transplanted aortas expressed increased levels of vascular cell adhesion molecule-1 and intracellular adhesion molecule-1 compared with the native vessels subjected to identical levels of cholesterolemia. Medial smooth muscle cells in transplanted aortas contained much higher levels of immunoreactive tumor necrosis factor-alpha than did medial cells of the native aorta in the same hypercholesterolemic animals. The intima of transplanted aortas contained prominent microvessels compared with the native aorta of the hypercholesterolemic rabbits. We conclude that even during treatment with doses of cyclosporine that control acute myocardial rejection, hypercholesterolemia and the allogeneic state act together to augment allograft atherosclerosis, T-cell accumulation, intimal neovascularization, local cytokine expression, and indices of cell activation in arteries
