Introduction:
Sample type recommended by the manufacturer for the digoxin Abbott assay is either serum collected in glass tubes or plasma (sodium heparin, lithium heparin, citrate, EDTA or oxalate as anticoagulant) collected in plastic tubes. In our hospital samples are collected in plastic tubes. Our hypothesis was that the serum sample collected in plastic serum tube can be used interchangeably with plasma sample for measurement of digoxin concentration. Our aim was verification of plastic serum tubes for determination of digoxin concentration.Materials and methods:
Concentration of digoxin was determined simultaneously in 26 venous blood plasma (plastic Vacuette, LH Lithium heparin) and serum (plastic Vacuette, Z Serum Clot activator; both Greiner Bio-One GmbH, Kremsmünster, Austria) samples, on Abbott AxSYM analyzer using the original Abbott Digoxin III assay (Abbott, Wiesbaden, Germany). Tube comparability was assessed using the Passing Bablok regression and Bland-Altman plot.Results:
Serum and plasma digoxin concentrations are comparable. Passing Bablok intercept (0.08 [95% CI = −0.10 to 0.20]) and slope (0.99 [95% CI = 0.92 to 1.11]) showed there is no constant or proportional error.Conclusion:
Blood samples drawn in plastic serum tubes and plastic plasma tubes can be interchangeably used for determination of digoxin concentration. 相似文献3.

Moisture is a driving factor in the long-term mechanical deterioration of canvas paintings, as well as for a number of physico–chemical degradation processes. Since the 1990s a number of publications have addressed the equilibrium hygroscopic uptake and the hygro-mechanical deformation of linen canvas, oil paint, animal glue, and ground paint. In order to visualise and quantify the dynamic behaviour of these materials combined in a painting mock-up or reconstruction, we have performed custom-designed experiments with neutron radiography and nuclear magnetic resonance (NMR) imaging. This paper reports how both techniques were used to obtain spatially and temporally resolved information on moisture content, during alternate exposure to high and low relative humidity, or in contact with liquids of varying water activities. We observed how the canvas, which is the dominant component in terms of volumetric moisture uptake, absorbs and dries rapidly, and, due to its low vapour resistance, allows for vapour transfer towards the ground layer. Moisture desorption was generally found to be faster than absorption. The presence of sizing glue leads to a local increase of moisture content. It was observed that lining a painting with an extra canvas results in a damping effect: i.e. absorption and drying are significantly slowed down. The results obtained by NMR are complementary to neutron radiography in that they allow accurate monitoring of water ingress in contact with a liquid reservoir. Quantitative results are in good agreement with adsorption isotherms. The findings can be used for risk analysis of paintings exposed to changing micro-climates or subjected to conservation treatments using water. Future studies addressing moisture-driven deformation of paintings can make use of the proposed experimental techniques. 相似文献

Despite efforts to desegregate and promote equal opportunity, Black students have a minimal role in gifted programs. Efforts to improve this situation must begin with a focus on the individual student. Classroom teachers need assistance from gifted and talented coordinators with nomination procedures. Information regarding standardized tests, perceptions of low achievement, and the characteristics of Black achievers is essential for improving nomination. The second step to increasing minority participation in gifted programs is to implement a multi‐criteria assessment profile. Compiled by the gifted and talented coordinator with the continued assistance of the classroom teacher, this profile should include a case study documenting gifted characteristics, family background information, and peer evaluations. Standardized test scores may play a minor role. Successful identification of gifted Black students depends on a thorough examination of the individual. 相似文献

Evidence‐based classwide interventions have the potential to help a large number of students by preventing problem behaviors before they become a significant problem in the classroom. Results of a study examining the effectiveness of a classwide peer‐modeling intervention package to improve students' on‐task behavior in the classroom are presented. The classwide intervention took place in three mixed‐grade classrooms (third/fourth, fourth/fifth, and fifth/sixth) with 14–20 students each. Fifteen‐minute intervention sessions occurred approximately two times a week for a total of six to eight sessions. During each intervention session, students watched a 4‐minute videotape segment depicting a peer model demonstrating near 100% on‐task behavior, which was accompanied by verbal coaching and small tangible rewards. Results demonstrated large treatment effects across all three classrooms, which remained large in two of the classrooms at follow‐up 4–8 weeks later. Corresponding positive social validity by participating students and teachers was also documented. Results are discussed in terms of implications, limitations, and future research directions. © 2010 Wiley Periodicals, Inc. 相似文献

Although a plethora of research focuses on economically at-risk preschool children in general across the United States, little can be found that investigates methods for improving rural children’s academic outcomes. This review of research is intended to provide a contextual understanding of the background and current conditions that exist for rural preschool children and their families in America, and to recommend strategies for improving adverse cognition and learning conditions, including a lack of early literacy skills, and low high school completion rates that frequently are found in this population, utilizing the Common Core State Standards (CCSS) as a framework. Attention will be given to demographics, academic performance and scientifically-based practices proven to impact both teaching and learning for rural preschool children, particularly those from minority households, incorporating the newly developed CCSS. A comparison will be made between rural white and African American children’s learning and cognition, highlighting significant disparities for African American students, despite the fact that they make up less than 10 % of all rural preschool children. For the scope of this study, rural communities will be defined as those with varying qualities situated outside of metropolitan areas. Results from this study reveal the conditions for rural preschool children, especially those from African American families with low-income levels. Findings indicate that providing training for teachers, administrators and families linked to rural schools; and infusing CCSS into the rural preschool curricula significantly improves school readiness, and decreases dropout rates. 相似文献

Objectives: This study compared the mapping of natural language patron terms to the Medical Subject Headings (MeSH) across six MeSH interfaces for the MEDLINE database.Methods: Test data were obtained from search requests submitted by patrons to the Library of the Health Sciences, University of Illinois at Chicago, over a nine-month period. Search request statements were parsed into separate terms or phrases. Using print sources from the National Library of Medicine, Each parsed patron term was assigned corresponding MeSH terms. Each patron term was entered into each of the selected interfaces to determine how effectively they mapped to MeSH. Data were collected for mapping success, accessibility of MeSH term within mapped list, and total number of MeSH choices within each list.Results: The selected MEDLINE interfaces do not map the same patron term in the same way, nor do they consistently lead to what is considered the appropriate MeSH term.Conclusions: If searchers utilize the MEDLINE database to its fullest potential by mapping to MeSH, the results of the mapping will vary between interfaces. This variance may ultimately impact the search results. These differences should be considered when choosing a MEDLINE interface and when instructing end users. 相似文献

The notion that parent involvement impacts student learning outcomes for children who are at risk for failing academically has been supported by prominent early childhood education experts. Recent attention has been given to specific ways parents can help increase student learning through their interactions with children as they complete home learning activities. It is important to note that the term parent is used interchangeably with the terms adult, guardian and family member. The term “at-risk reader” refers to readers who are at risk of failing school because of reading deficiencies. This report will examine whether parent training to increase parent–child interactions during the completion of second grade Interactive Homework Assignments (IHA) can facilitate increases in a student’s ability to draw inferences from reading selections, a skill closely aligned with proficiency in reading acquisition. The second grade level was chosen because these children were those whose teachers were concerned with preparing them to take the third grade SAT9. Third grade level was not selected because many of their professional development activities were prescribed due to their immediate concern with preparing students to take the SAT9. IHA, for the scope of this study, is homework designed to increase parent involvement and student achievement. The results indicate that specific parent training during a brief period of time, approximately four weeks, has the potential for improving academic performance for academically at-risk students. 相似文献

This study examined the relationship between polyvictimization, psychological distress, and trauma symptoms in college men and women. Childhood victimization was common among participants. Regression analyses revealed that polyvictimization (i.e., high cumulative levels of victimization) is a better predictor of psychological distress and trauma symptoms than is any individual category of victimization (i.e., sexual, physical, peer/sibling, child maltreatment, witnessing/indirect, or property crime). Gender did not moderate the relation between victimization and distress and trauma symptoms. Implications for counselors are discussed. 相似文献
