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

This article presents the practical application of the public relations process through an analysis of its consecutive phases with reference to the Wrocl?aw University of Economics, Poland. The author examines the four phases of the process (research, action, communication, and evalu ation), concentrating on the first phase, situation analysis. The diagnostic phase is based on research that was carried out among students of the university that gave rise to a sample consisting of 1,123 respondents to a questionnaire. The main aim of the research was to identify the opinions and attitudes of students in regard to their university, their evaluation of the way it functions, and their perceptions of its image. 相似文献

The article presents the results of a study focusing on the family situation, education and interpersonal relations of adults (26–35 years old) who in their adolescence (16–19 years old) displayed exceptional giftedness. One group of those surveyed were national academic award winners (90). The control group consisted of 90 people of no outstanding academic achievement. The research found many differences between these two groups, both in the family situation and in interpersonal relations. High achievers were raised in families of higher social and professional status, and almost 72.2% of them decided to continue their academic career after they had graduated from university. The national academic award winners showed higher scores in shyness and lower scores in sociability in interpersonal relations. 相似文献

The article presents a report on four 45 minute sessions with a group of 17 year old humanities students. These sessions were the first of a series organised with the aim of exploring the possibilities of elaborating didactical situations that would help the students overcome epistemological obstacles related to limits. Students' attitudes pertinent to the development of the notion of limit, as well as changes of these attitudes, are described and analysed. 相似文献

The precise etiology and reasons for the increase in incidence of autoimmune disorders still remain unclear, and although both genetic and environmental factors have been proven to shape individual predisposition, it is not known which of the factors, if not both, is responsible for the boom observed during the last decades. In order to establish whether a higher frequency of autoimmune-predisposing alleles may explain this increase we took advantage of ancient DNA methodology to establish the genetic predisposition, conferred by cytotoxic T lymphocyte associated antigen-4 （CTLA4） ＋49A/G and human leukocyte antigens （HLA） DQBI^57, in population inhabiting Poland in the Middle Ages. After successful typing of 42 individuals from a 12th-14th＇s century archeological burial site, we found that frequencies of the predisposing alleles in the medieval population were higher than they are at present, suggesting thus that the recently observed incidence increase results most probably from factors of other than genetic nature. 相似文献

This article focuses on the problems of adults who in secondary school were high ability learners. The main point of interest of the research presented here is job satisfaction among gifted people and their temperament structure. The authors are interested whether there exist correlations between the investigated variables both in the entire group of gifted individuals as well as in the subgroup of those gifted in the humanities and in the control group. The research results show that between the group of gifted people and the control group there appear significant differences in vigorousness (VG) and activity (AC). The studied groups differ as to the kind and extent of the fulfilment of expectations concerning professional career. Gifted individuals, in comparison to the control group, are more satisfied with their jobs. 相似文献

A 1D chain of coupled oscillators is considered, including the Duffing-type nonlinearity, viscous damping, and kinematic harmonic excitation. The equations of motion are presented in a non-dimensional form. The approximate equations for the vibrational amplitudes and phases are derived by means of the classical averaging method. A simple analysis of the resulting equations allows one to determine the conditions for the two basic synchronous steady-states of the system: the in-phase and anti-phase motions. The relations between the required excitation frequency and the natural frequencies of the abbreviated (linear) system are discussed. The validity of these predictions is examined by a series of numerical experiments. The effect of the model parameters on the rate of synchronization is analyzed. For the purpose of systematic numerical studies, the cross-correlation of time-series is used as a measure of the phase adjustment between particular oscillators. Finally, some essential issues that arise in case of the mechanical system with dry friction are indicated. 相似文献
