Despite ample sunshine, 50–90% Indian children have Vitamin D deficiency (VDD). This enigma of widespread VDD needs exploration especially among under-fives as physiological variations in Vitamin D Binding Protein (VDBP) levels could be potential confounders in the interpretation of total 25-hydroxyvitamin D [25(OH)D]. However, there is scarce information about relevance of VDBP levels in under-five age group. We therefore, explored association of VDBP levels among 1–5 year old children with VDD. Serum levels of 25(OH)D, VDBP, calcium, parathyroid hormone (PTH) and alkaline phosphatase were estimated in 210 apparently healthy children in the age group of 1–5 years. VDD was defined as serum 25(OH)D levels < 20 ng/ml as per the IOM classification. VDBP levels were classified as low if levels were < 168 μg/ml as per the kit. The prevalence of VDD was 79.5% (n = 167) and VDBP levels were low in 48.6% (n = 102) of children. 25(OH)D levels correlated positively with VDBP (r = 0.298, p = 0.0001). A significant number of children (52.7%) with VDD had low VDBP (p = 0.015). and despite adequate sun exposure, 43% of children showed VDD and 56.6% had low VDPB levels. The low VDBP levels largely explain low 25OHD levels without necessarily implying VDD. It may add a new dimension for better understanding of widespread VDD among under-five children. It thus, points towards the need for redefining cut offs and complete evaluation of vitamin D status among under-fives including VDBP. 相似文献

As higher education begins to operate increasingly in a European framework, consequences for the assurance of quality in higher education are bound to become evident. A pilot study to develop a methodology for the comparison of quality across different higher education systems is described. The project involved comparison of ten study programmes in economics in Germany, the Netherlands, and the United Kingdom. A design derived from general considerations about the concept of quality and about the nature of higher education and different systems incorporated two stages. First was the collection of information and the processing of this information into manageable data sets; second was the assessment of the information by way of peer review. The proceedings and principal findings of both stages followed the overview of the project design. The article concludes by highlighting some implications of this pilot project for the future of quality assurance in higher education on a European scale. 相似文献

Currently employed markers for the detection of acute coronary syndrome are Troponin T, CK (Creatine Kinase) and CKMB activity. CKMB activity measured by immunoinhibition method can give falsely elevated results due to the presence of atypical CK and CKBB and at times lead to the mis-diagnosis of acute coronary syndrome. Hence, CKMB mass (CKMB) measured by electrochemiluminence sandwich principle was employed. In this cross-sectional study 183 samples of 61 patients were analyzed within 6 h of diagnosis of acute coronary syndrome and followed up to 72 h. The correlation coefficient between CKMB activity and CKMBM at 4–6 h was 0.744, while at 12–24 h it was 0.909 and at 48–72 h it was 0.337. Thus there was good association between the two methods at 12–24 h but, statistically for method comparison studies and for replacing one method by another, the two methods need to be in agreement with one another. In this study the two methods are not in agreement with one another and thus analytically not replaceable. Another finding was obtained that CKMBM reached cut off levels prior to CKMB enzyme activity and hence, CKMBM is clinically better than CKMB activity to detect reinfarction. 相似文献

Innovative new ventures are at the heart of economic development, particularly when these startups are created by employee, academic, and user innovators. We synthesize across literature streams examining each phenomena to document distinctions between firms originating from different “knowledge contexts.” We then integrate the knowledge context into Teece's (1986) theoretical framework identifying factors that impact a firm's ability to profit from innovation. Doing so allows us to develop stylized facts and predictive propositions pertaining to differences in the innovative contributions, roles played in shaping industrial dynamics and evolution, and performance outcomes for startups stemming from the three entrepreneurial origins. These propositions provide unique insights into the causes of patterns of industry evolution, contribute to theory in the areas of entrepreneurship and industry evolution, and yield important policy and managerial implications. 相似文献

This essay explores the complexity of imposing texts that are considered part of the English literary canon on students from multicultural backgrounds. It considers the rhetoric of the coalition government, in the recent drive to emphasize the importance of the literary heritage and return to English culture and how its impact has been felt in the classroom. It focuses mainly on the teaching of The Scarlet Letter to a Year 9 class and the issues presented when teaching it to a class of learners from very different ethnic backgrounds. It considers whether the true value of studying these texts is worthwhile for very different reasons from the social and cultural ones that have driven recent educational policy in England. 相似文献
