Purpose
Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.Materials and methods
The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m2, n=40) and II (BMI<25 kg/m2, n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).Results
A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.Conclusions
The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.2.
The article forms an analysis of the religious discrimination discourse in Polish public schools, with special attention paid to the culturally specific, Polish understanding of the notion of religious discrimination. The introductory part presents the concept of religious discrimination as present in anti-discriminatory policies. The following part outlines the Polish system of religious education and its relation to the religious discrimination. Studies on religious discrimination in Poland are presented and discussed. Important context is supplied by a presentation of two recent cases of religious discrimination in Polish public schools, and the actions undertaken by the Freedom from Religion Foundation. Authors of the article point out the important influence of cultural context on the perception of religious discrimination. The attention is drawn to the seemingly homogenous environment of the Polish school and of the discriminative discourse used in political and social debates. The analysis shows that the presence of religion as a subject in Polish schools remains a cause of conflict between the religious and atheist citizens, a conflict in which concepts of religious discrimination and religious freedom are used as arguments by both sides. 相似文献

There is no need nowadays to convince people that modern education cannot function properly without the help of scientific research, and especially of pedagogical research. It is true that there still appear many pedagogical works inflated by wind, as Comenius expressed it more than three hundred years ago, and these publications may even acquire a temporary popularity. But the general trend towards the development of pedagogy as a discipline based on research has been established for quite some time and is constantly gaining strength in the developed countries. Concurrently, pedagogical disciplines have had increasing influence on the development of education.The question of how these disciplines have developed in Poland and how they have influenced the educational system calls for a broader review, such as to allow one to draw conclusions on how to harmonise more effectively the domain of educational research with that of education. Such a review is the aim of the present paper. The following issues are considered: the functions of educational research, the kinds of educational investigations conducted in Poland, ways of disseminating their findings, and the organisation of research in Poland. The paper ends with a discussion of some of the more important conclusions reached.
Zusammenfassung Heutzutage ist es nicht mehr nötig, viele Worte darüber zu verlieren, daß ein modernes Bildungswesen ohne Unterstützung durch wissenschaftliche, insbesondere pädagogische Forschung nicht richtig funktionieren kann. Zwar erscheinen immer noch viele pädagogische Arbeiten, die vom Wind aufgeblasen sind, wie sich Comenius vor über 300 Jahren ausdrückte, und diese können sogar zeitweilig grossen Anklang finden. Aber der allgemeine Trend, die Pädagogik als eine auf Forschung beruhende Disziplin anzusehen, besteht seit längerer Zeit und verstärkt sich in den Industrieländern ständig. Gleichzeitig üben pädagogische Disziplinen zunehmenden Einfluß auf die Entwicklung des Bildungswesens aus.Die Frage, wie sich diese Disziplinen in Polen entwickelt und wie sie das Bildungssystem beeinflußt haben, erfordert eine umfassendere Übersicht, die es ermöglicht, Schlußfolgerungen darüber zu ziehen, wie die pädagogische Forschung am besten mit dem Bildungswesen harmonisiert werden kann. Eine solche übersicht versucht der vorliegende Artikel zu geben. Er behandelt die folgenden Themen: die Funktionen der pädagogischen Forschung; die Art der in Polen angestellten Untersuchungen; die Verbreitungsmöglichkeiten ihrer Ergebnisse; und die Organisation der Forschung in Polen. Abschließend werden einige der wichtigeren Schlußfolgerungen besprochen.
Résumé De nos jours il n'est plus nécessaire de convaincre les gens que l'éducation moderne ne peut fonctionner de façon satisfaisante sans l'aide de la recherche scientifique, et plus spécialement de la recherche pédagogique. Il est vrai que l'on voit encore paraître de nombreux ouvrages pédagogiques gonflés de vent comme le disait déjà Comenius il y a plus de trois siècles, et ces publications peuvent éventuellement connaître une popularité passagère. Mais le courant général selon lequel la pédagogie est une discipline en developpement basée sur la recherche est désormais irréversible et il prend sans cesse plus d'importance dans les pays développés. Concurrement, les disciplines pédagogiques exercent une influence croissante sur le développement de l'éducation.Comment ces disciplines se sont-elles développées en Pologne et comment y ontelles influencé le système de l'éducation, sont deux questions qui demandent une étude approfondie si l'on veut en tirer des conclusions permettant d'harmoniser plus efficacement le domaine de la recherche en éducation et celui de l'éducation. C'est là l'objet de cet article. L'auteur considère les fonctions de la recherche en éducation, les différentes sortes d'enquêtes éducationnelles menées en Pologne, les moyens de diffusion des résultats et l'organisation de la recherche dans ce pays. Il termine par une discussion des conclusions les plus importantes auxquelles les Polonais sont parvenus.相似文献

To prepare a biosynthetic module in an infochemical communication project, we designed a silicon/glass microreactor with anti-adsorption polyelectrolyte multilayer coating and immobilized alcohol acetyl transferase (atf), one of the key biosynthetic enzymes of the pheromone of Spodoptera littoralis, on agarose beads inside. The system reproduces the last step of the biosynthesis in which the precursor diene alcohol (Z,E)-9,11-tetradecadienol is transformed into the major component (Z,E)-9,11-tetradecadienyl acetate. The scope of this study was to analyze and implement a multilayer, anti-adsorption coating based on layer-by-layer deposition of polyethylenimine/dextransulfate sodium salt (PEI/DSS). The multilayers were composed of two PEI with molecular weights 750 and 1.2 kDa at pH 9.2 or 6.0. Growth, morphology, and stability of the layers were analyzed by ellipsometry and atomic force microscopy (AFM). The anti-adsorption functionality of the multilayer inside the microreactor was validated. The activity of His(6)-(atf) was measured by gas chromatography coupled to mass spectrometer (GC-MS). 相似文献

Early career researchers (ECRs) are of great interest because they are the new (and biggest) wave of researchers. They merit long and detailed investigation, and towards this end, this overarching paper provides a summary of the first‐year findings of a 3‐year, longitudinal study of 116 science and social science ECRs who have published nearly 1,200 papers and come from 7 countries and 81 universities. ECRs were interviewed in their own languages face‐to‐face, by Skype, or telephone. The study focused on the attitudes and behaviours of ECRs with respect to scholarly communications and the extent to which they are adopting new and disruptive technologies, such as social media, online communities, and Open Science. The main findings include: publishing in high‐impact factor journals is the only reputational game in town; online scholarly communities, and ResearchGate in particular, are gaining ground; social media are beginning to have an impact, especially in the dissemination arena; outreach activities have become more important; libraries are becoming increasingly invisible to ECRs; Open Science is not gaining traction; and more transformational ideas are being expressed, especially in the US and UK. 相似文献
