Role of director of a kindergarten in shaping school culture
Thesis deals with the role of the director of a kindergarten within shaping of the school culture and with the potential of school culture in terms of contemporary education. Thesis focuses on the factors which the director influences the most and which leads to increased level of quality of teachers' work. In the theoretical part the emphasis is on understanding the concepts in the school culture, school climate, management and leadership and also on relationships in kindergarten, which create and develop a quality society. Further, the thesis concerns the research investigation, which detects the orientation of the issue of school culture and current use of knowledge in connection to the management of kindergarten. Key words Kindergarten surrounding, communication, kindergarten culture, interpersonal relationships, labor relations, director, employee satisfaction, styles of management
Table_1_Unbiased screen for pathogens in human paraffin-embedded tissue samples by whole genome sequencing and metagenomics.xlsx
Identification of bacterial pathogens in formalin fixed, paraffin embedded (FFPE) tissue samples is limited to targeted and resource-intensive methods such as sequential PCR analyses. To enable unbiased screening for pathogens in FFPE tissue samples, we established a whole genome sequencing (WGS) method that combines shotgun sequencing and metagenomics for taxonomic identification of bacterial pathogens after subtraction of human genomic reads. To validate the assay, we analyzed more than 100 samples of known composition as well as FFPE lung autopsy tissues with and without histological signs of infections. Metagenomics analysis confirmed the pathogenic species that were previously identified by species-specific PCR in 62% of samples, showing that metagenomics is less sensitive than species-specific PCR. On the other hand, metagenomics analysis identified pathogens in samples, which had been tested negative for multiple common microorganisms and showed histological signs of infection. This highlights the ability of this assay to screen for unknown pathogens and detect multi-microbial infections which is not possible by histomorphology and species-specific PCR alone.</p

Schematic overview of the four different JUP isoforms.
<p>JUP-81 and JUP-63 have an identical N-terminus (the N-terminal 303 amino acids), and JUP-63 further shares its C-terminus with cytokeratin 19 (K1C19). The sequences of JUP-55 and JUP-30 are currently unknown but they contain epitopes that are shared with JUP-81 and are thought to be located in the N-terminal region of native JUP. JUP-30 lacks (at least) the N-terminal 50 amino acids of JUP-81. JUP-81, which is also referred to as gamma-catenin, is furthermore homologous to beta-catenin. Amino acids 1, 303 and 745 of JUP-81 are indicated with arrows.</p
Thrombendarterectomy tissue for secretome production and immunohistochemistry.
<p>a) Tissue sample as it was received from the surgical department. b) The tissue was separated into the plaque part (I) for production of the plaque secretome, and the best preserved part (II) for production of the control secretome.</p
Schematic presentation of the selection strategy.
<p>a) The phage library, containing billions of different phages, was amplified from the bacterial stock. ScFv are fused to minor coat protein III and as such displayed on the phage surface. b) In a subtraction step, the phage library was incubated with secretome from the healthy control tissue. Binders to common proteins were removed in this way. c) Phages that did not bind to the control secretome were incubated with the atherosclerotic secretome in this panning step. d) Unbound phages were washed off, and e) bound phages were eluted and used to infect a suitable <i>E.coli</i> strain (<i>E.coli</i> TG1). f) Bacteria infected with the selected and eluted phages were plated on large agar plates. g) To further enrich for phages that specifically bind to the atherosclerotic secretome, the selection round was repeated. h) Single colonies were induced to produce monoclonal phages. i) Monoclonal phages were analysed for their reactivity with atherosclerotic versus control secretomes in ELISA. In total, six different selections were performed. For each separate selection the control and atherosclerotic secretomes from one individual patient were used. In order not to loose diversity, only two subtractive panning rounds were performed for each selection. To analyse whether enrichment of atherosclerotic secretome-specific binders had taken place, polyclonal phage pools (as obtained in step a) after each subtractive panning round (and of the unselected library as a control) were analysed in ELISA for reactivity with atherosclerotic and control secretomes.</p

Detection of JUP in plaques by immunohistochemistry and in secretome by immunoblotting.
<p>a) Overview of JUP immunoreactivity on endarterectomised tissue. Strong staining in the atherosclerotic plaque tissue is observed. b) Clockwise from top left (400-fold magnification): H&E staining (1), anti-CD68 (2), negative control (3), and anti-JUP staining (4). c and d) Six plaque secretomes (lanes 1–6), two control secretomes (lanes 7 and 8) and GST-tagged JUP (lane 9, 107 kD) were immunoblotted with anti-JUP mAb 2C9 (c) and scFv 25G5 (d). e) Competition experiment with mAb 2G9 (which replaced 2C9). Western blots containing recombinant GST-tagged JUP (lane 1, 107 kD), ACS plasma (lane 2), and secretome (4.5 µl in lane 3 and 1.9 µl in lane 4) were incubated with mAb 2G9, which was (blot on the right) or was not (blot on the left) pre-incubated with soluble, recombinant GST-tagged JUP protein. f) Competition experiment with scFv 25G5. Western blots containing different amount of atherosclerotic plaque secretome (lane 1∶4.5 µl, lane 2∶1.9 µl, lane 3∶0.9 µl, lane 4∶0.4 µl) were incubated with scFv 25G5, which was (blot on the right) or was not (blot on the left) pre-incubated with soluble, recombinant GST-tagged JUP protein. For all immunoblots: known molecular weights of protein markers are depicted on the left and estimated molecular weights of detected protein bands are depicted on the right of both Western blots.</p
