We measured serum soluble vascular endothelial growth factor receptor 1 (sVEGFR1) and receptor 2 (sVEGFR2) levels in healthy Japanese individuals in order to establish a reference value using a specific ELISA. Significant differences were observed in serum sVEGFR1 and sVEGFR2 levels between children and adults. To demonstrate the usefulness of the reference value for children, we measured serum sVEGFR1 and sVEGFR2 levels in children with diarrhea positive (D+) hemolytic uremic syndrome (HUS) as a preliminary study. Serum sVEGFR2 levels in children with HUS were markedly higher than those in healthy children from the onset of D + HUS. The reference value for healthy children in the present study will allow normal and pathological conditions to be discriminated from each other in future study 相似文献

This article provides an overview of open government data. It outlines what it is, provides examples, and summarizes library engagement with these data. The professional and academic literature and other web sources were examined along with government policies and portals. Open government data is a fairly recent and evolving phenomenon that promotes government transparency and invites citizen participation and innovative reuses of public data. Libraries have been responding to this release of data in a number of ways including offering data literacy instruction and special services and programs. 相似文献

Although librarians’ increasingly important role as teachers is among the most significant shifts and trends that have been reshaping academic libraries over the past few decades, most academic librarians have not received formal training in pedagogy and teaching. The authors describe how becoming familiar with educational theory and research enabled them to revamp freshmen library workshops. They provide a theoretical overview and present practical classroom applications of learning styles theory, active learning techniques, learning by analogies, collaborative learning, and group work. Learning theories and educational research findings, the authors suggest, can be readily translated into practice and inform the teaching of information literacy to freshmen. 相似文献

Objective
Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation.Methods
In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation.Results
The study demonstrated that low doses (10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam (10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples.Conclusions
Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics. 相似文献7.

墨家认为,人是追求实现自己欲求的能动性的存在,秩序不否定却利用这个欲求而得以形成。於兼爱论在追求＂利＂的过程中,通过＂利＂的交换形成秩序。於尚同论在追求＂义＂的过程中,通过对上位者＂调谐＂形成秩序。於是尚同论呈现＂专制主义＂的外貌,可是在这样的过程之中,虽然上位者也受下位者的＂规谏＂,下位者的＂义＂也不否定了。秩序肯定着各人追求欲求的行动。墨家的社会是动态的、发展的、追求进一步富裕的和谐社会。 相似文献

We examined preschool children's use of count information in making quantity judgments. Study 1 involved 35 children 3–5 years old using a balance-scale task to judge relative quantity with or without count information provided. Study 2 replicated and extended the exploration as 54 children 3–4 years old judged relative quantity in multiple counting contexts. Children who were given count information successfully used count information in quantity evaluation when visual cues were not useful. Limited experience of counting skills, strategy choice, and limited processing capacity are each discussed as potential explanations. Implications for early childhood practice and teacher education, as well as directions for future research are explored. 相似文献

The authors examine, based on a survey of users, the electronic document delivery methods currently in place as well as changes in the recent past and future developments. Interlibrary loan and document delivery staff from institutions across the United States were surveyed in order to ascertain what document delivery mechanisms are currently in place, how they are being used, and why. Findings from this study should lead to an increased awareness of electronic delivery options in libraries across the country and elucidate the dynamics involved at individual sites. This, in turn, will assist librarians in making decisions, based not only on their individual circumstances but on the experiences and trends found across a broad sampling of institutions. 相似文献
