Study of omega-meson production in pp collisions at ANKE

The production of omega-mesons in the pp->pp omega reaction has been investigated with the COSY-ANKE spectrometer for excess energies of 60 and 92MeV by detecting the two final protons and reconstructing their missing mass. The large multipion background was subtracted using an event-by-event transformation of the proton momenta between the two energies. Differential distributions and total cross sections were obtained after careful studies of possible systematic uncertainties in the overall ANKE acceptance. The results are compared with the predictions of theoretical models. Combined with data on the phi-meson, a more refined estimate is made of the Okubo-Zweig-Iizuka rule violation in the phi/omega production ratio.Comment: 10 pages, 9 figures, version 1, submitted to EPJ-

Clinical Use and Therapeutic Potential of IVIG/SCIG, Plasma-Derived IgA or IgM, and Other Alternative Immunoglobulin Preparations

Intravenous and subcutaneous immunoglobulin preparations, consisting of IgG class antibodies, are increasingly used to treat a broad range of pathological conditions, including humoral immune deficiencies, as well as acute and chronic inflammatory or autoimmune disorders. A plethora of Fab- or Fc-mediated immune regulatory mechanisms has been described that might act separately or in concert, depending on pathogenesis or stage of clinical condition. Attempts have been undertaken to improve the efficacy of polyclonal IgG preparations, including the identification of relevant subfractions, mild chemical modification of molecules, or modification of carbohydrate side chains. Furthermore, plasma-derived IgA or IgM preparations may exhibit characteristics that might be exploited therapeutically. The need for improved treatment strategies without increase in plasma demand is a goal and might be achieved by more optimal use of plasma-derived proteins, including the IgA and the IgM fractions. This article provides an overview on the current knowledge and future strategies to improve the efficacy of regular IgG preparations and discusses the potential of human plasma-derived IgA, IgM, and preparations composed of mixtures of IgG, IgA, and IgM

The Problem of Forming the Subjective and Object Civilian Position of Young Citizen

Modern youth is subject to the influence of numerous trends, conditioned by fashion trends, the spread of marketing strategies of enterprises, the activities of various social and political associations. The author considers the problem of forming a civic position of a young urban citizen as an actualized search for personal self-realization in conditions of intensive information exchange and a large volume of virtual communications. The author notes that the modern citizen lives on the junction of real and virtual interactions, in the general mass of which the role of the latter increases its significance not only in the framework of education, but also in the sphere of feedback with organizations, enterprises and the sphere of state support. The actualization of the problem of self-identification of young people with the city appeared in the stable trends of mass outflow of the population from rural settlements, small towns, and also peripheral regions towards the capital regions. The need to increase the civic activity of urban youth in the author’s presentation is due to the tasks of developing the subject-object position of the population in relation to the region of residence. The article presents data of the content analysis of virtual communities devoted to the development and current events of city life. According to the results of the study, the author notes the criminalization of news reports, as well as the shortcomings in the timely submission of information to citizens. Evaluation of the structure of ads and motivating posts related to sympathy for a particular city made it possible to come to the conclusion that the formation of socially active behavior of citizens is largely oriented towards the leisure city complex, while much less attention is paid to active participation in city life. The threat of this trend is seen in the formation of the orientation of young people to the leisure attractions of individual regions.Современная молодежь подвержена влиянию многочисленных тенденций, обусловленных веяниями моды, распространением маркетинговых стратегий предприятий, деятельностью различных социальных и политических объединений. Проблема формирования гражданской позиции молодого горожанина рассматривается автором как актуализированный поиск самореализации личности в условиях интенсивного информационного обмена и большого объема виртуальных коммуникаций. Автор отмечает, что современный горожанин проживает на стыке реальных и виртуальных интеракций, в общей массе которых роль последних увеличивает свою значимость не только в рамках просвещения, но и в сфере обратной связи с организациями, предприятиями и сферой государственного обеспечения. Актуализация проблемы самоидентификации молодежи с городом появилась в устойчивых тенденциях массового оттока населения из сельских поселений, малых городов, а также периферийных районов в сторону столичных регионов. Необходимость повышения гражданской активности городской молодежи в представлении автора обусловлена задачами развития субъект-объектной позиции населения в отношении региона проживания. В статье приведены данные контент-анализа виртуальных сообществ, посвященных развитию и текущим событиям городской жизни. По результатам исследования автор отмечает криминализацию новостных сводок, а также недостатки своевременности подачи информации горожанам. Оценка структуры объявлений и мотивирующих постов, связанных с симпатиями к конкретному городу, позволила прийти к выводу, что формирование социально-активного поведения граждан во многом ориентировано на досуговый городской комплекс, в то время как деятельному участию в жизни города уделяется значительно меньше внимания. Угроза данной тенденции рассматривается в формировании ориентации молодежи на досуговую привлекательность отдельных регионов

Laparoscopic and open surgery with D3-lymphadenectomy in patients with left-sided colon cancer: clinical and pathological parallels

Aim of investigation. To evaluate morphological characteristics of the resected specimen after open and laparoscopic surgery with D3-lymphadenectomy for left-sided colon cancer. Material and methods. The investigation was designed as retrospective-prospective comparative case-match study. From archival cases and prospectively collected database cases with left-sided colon cancer stage I-III treated by complete mesocolic excision (CME) with D3-lymphadenectomy were selected. Patients who underwent open surgery formed the first group. The second group included patients after laparoscopic surgery. Results. Each group consisted of 54 patients. There were no significant differences in terms of age, gender, body mass index, tumor location, and tumor stage between the two groups. No statistically significant difference in specimen morphological characteristics after open and laparoscopic surgery with D3-lymphadenectomy for left-sided colon cancer was observed. Conclusion. The feasibility and safety of laparoscopic technique in treatment of left-sided colon cancer is reasonable regarding to the specimen quality. Similar clinical and pathological results suggest that there is no oncological difference between open and laparoscopic techniques with D3-lymphadenectomy for left-sided colon cancer. However, further studies are required to estimate long-term oncological results

Orthorhombic polar Nd-doped BiFeO3 thin film on MgO substrate

International audienceA Nd-doped BiFeO3 thin film deposited on MgO substrate was studied by synchrotron diffraction. The ferroelectric nature of the film is proven by in-plane remanent polarization measurement. The highest possible symmetry of the film is determined to be orthorhombic, within the Fm2m space group. Such a structure is rotated by 45 degrees with respect to the substrate and is consistent with tilts of oxygen octahedra doubling the unit cell. This polar structure presents a rather unusual strain-accommodation mechanism
