Introduction
Total 25-hydroxyvitamin D [25(OH)D] is the most reliable indicator of vitamin D status. In this study, we compared two automated immunoassay methods, the Abbott Architect 25-OH Vitamin D assay and the Roche Cobas Vitamin D total assay, with the liquid chromatography-tandem mass spectrometry (LC-MS/MS).Materials and methods
One hundred venous blood samples were randomly selected from routine vitamin D tests. Two of the serum aliquots were analyzed at the Abbott Architect i2000 and the Roche Cobas 6000’s module e601 in our laboratory within the same day. The other serum aliquots were analyzed at the LC-MS/MS in different laboratory. Passing-Bablok regression analysis and Bland-Altman plot were used to compare methods. Inter-rater agreement was analyzed using kappa (κ) analysis.Results
The Roche assay showed acceptable agreement with the LC-MS/MS based on Passing-Bablok analysis (intercept: -5.23 nmol/L, 95% CI: -8.73 to 0.19; slope: 0.97, 95% CI: 0.77 to 1.15). The Abbott assay showed proportional (slope: 0.77, 95% CI: 0.67 to 0.85) and constant differences (intercept: 17.08 nmol/L; 95% CI: 12.98 to 21.39). A mean bias of 15.1% was observed for the Abbott and a mean bias of -14.1% was observed for the Roche based on the Bland-Altman plots. We found strong to nearly perfect agreement in vitamin D status between the immunoassays and LC-MS/MS. (κ: 0.83 for Abbott, κ: 0.93 for Roche) using kappa analysis.Conclusion
Both immunoassays demonstrated acceptable performance, but the Roche Cobas assay demonstrated better performance than the Abbott Architect in the studied samples.Key words: 25-Hydroxyvitamin D, chromatography, immunoassay, methods, tandem mass spectrometry 相似文献3.

This paper is based on a quasi-experimental study which examines the effects of a school-based intervention on Omani girls’ attitudes towards the notion of gender equality. A questionnaire was administered before and after the intervention to 241 girls (116 in the experimental group; 125 in the control group). A semi-structured interview was conducted before and after the intervention with 16 participants (eight from the experimental group; eight from the control group). Analysis of quantitative data in the post-intervention round revealed statistically significant differences between the two groups in attitudes towards gender equality in favour of the experimental group. Similarly, the analysis of qualitative data from the post-intervention round showed that the experimental group differed significantly from the control group in its attitudes towards women’s roles and gender equality. The paper concludes by emphasising the critical role that education can play in challenging and transforming prejudicial and discriminatory attitudes. 相似文献

This study investigates the navigational patterns and learning achievement of university students with different cognitive styles, on hypermedia learning environments using paging or scrolling. The global–local subscales of Sternberg's Thinking Styles Inventory, two hypermedia, one using paging, the other using scrolling, a multiple choice achievement test, and a questionnaire to collect the students' satisfaction on paging/scrolling were used as data collection tools. This study finds that the cognitive style and paging/scrolling, together or separately, neither affected the learning nor the satisfaction of learners. Students with different cognitive styles using paging or scrolling did all learn well, with no statistically significant difference. Also the navigation patterns did not seem to depend on cognitive style; that is, the frequencies of using the navigation tools were not significantly different. 相似文献

THE ARTICLE present results of standardization of the Meadow-Kendall Social-Emotional Assessment Inventory for Deaf and Hearing-Impaired Students (Meadow, 1983), school-age version, for use in Turkey. The SEAI is a 59-item measure for assessing socioemotional adjustment of school-age deaf and hearing impaired students. A sample of 1,097 deaf students (609 boys, 488 girls), age range 7-19 years, was rated by their teachers (275 teachers: 149 female, 126 male) using the SEAI. Data were drawn from four types of educational settings: residential, day, special class, mainstream schools. Exploratory factor analysis of the data revealed three main factors of interest, which corresponded to the hypothesized constructs in the original American standardization: Social Adjustment, Self-Image, Emotional Adjustment. The data suggest high reliability and validity of the Turkish version of the SEAI relative to the original American version. Implications of adapting the SEAI for use in Turkey are discussed. 相似文献

Adult overhead athletes without a history of shoulder injury show scapular adaptations. There is a lack of detailed assessment of scapular kinematics in junior overhead athletes. This study aims to investigate three-dimensional scapular kinematics in junior overhead athletes. We recruited a total of 20 junior tennis players and 20 healthy children without participation in any overhead sports in this study. Bilateral scapular kinematic data were recorded using an electromagnetic tracking device for scapular plane glenohumeral elevation. The data were further analysed at 30°, 45°, 60°, 90° and 120° during glenohumeral elevation and lowering. Statistical comparisons of the data between groups (junior overhead athletes and non-overhead athletes) and sides (serve dominant and non-dominant shoulders of the overhead athletes) were analysed with the ANOVA. Comparisons showed that, in general, the scapula was more upwardly rotated and anteriorly tilted in overhead athletes when compared to non-overhead athletes, however there was no side-to-side differences when serve dominant and non-dominant shoulders compared in junior overhead athletes. The serve dominant arm of junior overhead athletes had alternations in scapular kinematics when compared with the non-overhead athletes. These findings provide clinical evaluation implications and the need for clinicians to assess for potential adaptations in junior overhead athletes. 相似文献

ABSTRACTThe potential relationships between innovation and sustainability processes, in engineering education, is neither obvious nor simple, especially when innovation, generally speaking, is promoted regardless of sustainability. We used UniLaSalle (In January 2016, the ‘Institut Polytechnique LaSalle Beauvais’, a French engineering school, merged with another higher education engineering school (ESITPA, Rouen). Both campuses (Beauvais and Rouen) have a common name: UniLaSalle (www.unilasalle.fr). As the interview began during 2015, this article only describes the situation of the Beauvais campus.) as a ‘living Lab’ to identify and analyse the reasons for the integration of innovation and Sustainable Development (SD) in training programmes. The aim is to explore, in a perception and reflective approach, how SD can be understood as a driver for specific innovation attitudes in higher education engineering school. This paper adopts an empirical approach based on a qualitative study, using NVivo 9 software to analyse non-numerical data. Our research suggests that SD can be a structural driver for innovation if it is integrated in a transdisciplinarity approach and not just as a discipline per se. 相似文献

Introduction:
Today, the pneumatic tube transport system (PTS) is used frequently because of its advantages related to timing and speed. However, the impact of various types of PTS on blood components is unknown. The aim of this study was to examine the influence of PTS on the quality of routine blood cell counts, erythrocyte sedimentation, and certain blood coagulation tests.Materials and methods:
Paired blood samples were obtained from each of 45 human volunteers and evaluated by blood cell count, erythrocyte sedimentation, and several coagulation tests, including prothrombin time (PT) and activated partial thromboplastin time (aPTT). Blood samples were divided into 2 groups: Samples from group 1 were transported to the laboratory via the PTS, and samples from group 2 were transported to the laboratory manually. Both groups were evaluated immediately by the tests listed above.Results:
The blood sample test results from groups 1 and 2 were evaluated and compared. No statistically significant differences were observed (P = 0.069–0.977).Conclusion:
The PTS yielded no observable effects on blood cell counts, erythrocyte sedimentation, or PT and aPTT test results. We concluded that the PTS can be used to transport blood samples and yield reliable results for blood cell counts, erythrocyte sedimentation, and several coagulation tests. 相似文献10.

This paper reports on an attempt to investigate Turkish primary school students’ interest in science by using their self-generated
questions. We investigated students’ interest in science by analyzing 1704 self-generated science-related questions. Among
them, 826 questions were submitted to a popular science magazine called Science and Children. Such a self-selected sample
may represent a group of students who have a higher level of motivation to seek sources of information outside their formal
education and have more access to resources than the students of low social classes. To overcome this problem, 739 students
were asked to write a question that they wanted to learn from a scientist and as a result 878 questions were gathered. Those
students were selected from 13 different schools at 9 cities in Turkey. These schools were selected to represent a mixture
of socioeconomic areas and also to cover different students’ profile. Students’ questions were classified into two main categories:
the field of interest and the cognitive level of the question. The results point to the popularity of biology, astrophysics,
nature of scientific inquiry, technology and physics over other science areas, as well as indicating a difference in interest
according to gender, grade level and the setting in which the questions were asked. However, our study suggests that only
considering questions submitted to informal learning environments, such as popular science magazines or Ask-A-Scientist Internet
sites has limitations and deficiencies. Other methodologies of data collection also need to be considered in designing teaching
and school science curriculum to meet students’ needs and interest. The findings from our study tend to challenge existing
thinking from other studies. Our results show that self-generated questions asked in an informal and a formal setting have
different patterns. Some aspects of students’ self-generated questions and their implications for policy, science curriculum
reform and teaching are discussed in this paper. 相似文献
