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.

In recent years, an increasing number of students with specific learning disabilities (SLDs) have enrolled in universities. The present exploratory study examined the frequency of use and appreciation of universal (open to every student) and specific services (offered to students with SLDs) and their relation to age, academic achievement, satisfaction, self-efficacy, and use of self-regulated learning (SRL) strategies. Participants were 147 Italian university students with SLD diagnoses (42 males; mean age: 22.49, SD = 3.29). Results showed that, overall, the frequency of use and appreciation of specific services were positively related to academic satisfaction, self-efficacy, and SRL strategies. Furthermore, frequency of use of compensatory tools and dispensatory measures was positively associated with academic achievement. These findings suggest that universities play an important role in supporting students with SLDs during their academic years by providing them with useful services and accommodations. 相似文献

影响力最大化问题是发现网络中的若干节点作为种子节点,使得影响力在网络中的传播最大化.基于投票模型,研究了移动通信网络中的影响力最大化问题.首先,根据用户以及用户间的短消息交互信息生成一个社会关系图.其次,每个用户对其最亲密的邻居进行投票.由于每个用户只能投一票,而其最亲密的邻居可能有多个,按照用户的活跃度对这些亲密的邻居进行排序,并且只对最活跃的邻居进行投票.最后,按照用户得票数对影响力进行排序,并返回排名靠前的若干个.通过对真实的移动通信数据集进行分析验证本文算法的有效性. 相似文献

加拿大英语除了具有鲜明的创新性特点以外,其保守性特点也很突出。18世纪末英国殖民者将当时的英语带到北美。随着时代的变迁,英语在祖国发生了变化,但大洋彼岸因种种因素没有发生同样的变化。因此在今天的加拿大英语中却仍可寻到昔日英国英语的痕迹。这在语音、词汇和语法方面均有体现。加拿大英语保守性特点的成因主要有语言接触因素、社会因素和移民源的心理因素。通过对加拿大英语保守性特点及其成因的分析,有助于英语的学习与传播。 相似文献

Home advantage in team games is well proven and the influence of the crowd upon officials' decisions has been identified as a plausible cause. The aim of this study was to assess the significance of home advantage for five event groups selected from the Summer Olympic Games between 1896 and 1996, and put home advantage in team games in context with other sports. The five event groups were athletics and weightlifting (predominantly objectively judged), boxing and gymnastics (predominantly subjectively judged) and team games (involving subjective decisions). The proportion of points won was analysed as a binomial response variable using generalized linear interactive modelling. Preliminary exploration of the data highlighted the need to control for the proportion of competitors entered and to split the analysis pre- and post-war. Highly significant home advantage was found in event groups that were either subjectively judged or rely on subjective decisions. In contrast, little or no home advantage (and even away advantage) was observed for the two objectively judged groups. Officiating system was vital to both the existence and extent of home advantage. Our findings suggest that crowd noise has a greater influence upon officials' decisions than players' performances, as events with greater officiating input enjoyed significantly greater home advantage. 相似文献
