    APP is assumed to play a role in causing Alzheimer,s disease. Its biological functions in the human body are currently unknown but of increasing interest in basic research, especially in investigating the process of wound healing [source]


    UNCOUPLING OF SILICON COMPARED WITH CARBON AND NITROGEN METABOLISMS AND THE ROLE OF THE CELL CYCLE IN CONTINUOUS CULTURES OF THALASSIOSIRA PSEUDONANA (BACILLARIOPHYCEAE) UNDER LIGHT, NITROGEN, AND PHOSPHORUS CONTROL1

    JOURNAL OF PHYCOLOGY, Issue 5 2002
    Pascal Claquin
    The elemental composition and the cell cycle stages of the marine diatom Thalassiosira pseudonana Hasle and Heimdal were studied in continuous cultures over a range of different light- (E), nitrogen- (N), and phosphorus- (P) limited growth rates. In all growth conditions investigated, the decrease in the growth rate was linked with a higher relative contribution of the G2+M phase. The other phases of the cell cycle, G1 and S, showed different patterns, depending on the type of limitation. All experiments showed a highly significant increase in the amount of biogenic silica per cell and per cell surface with decreasing growth rates. At low growth rates, the G2+M elongation allowed an increase of the silicification of the cells. This pattern could be explained by the major uptake of silicon during the G2+M phase and by the independence of this process on the requirements of the other elements. This was illustrated by the elemental ratios Si/C and Si/N that increased from 2- to 6-fold, depending of the type of limitation, whereas the C/N ratio decreased by 10% (E limitation) or increased by 50% (P limitation). The variations of the ratios clearly demonstrate the uncoupling of the Si metabolism compared with the C and N metabolisms. This uncoupling enabled us to explain that in any of the growth condition investigated, the silicification of the cells increased at low growth rates, whereas carbon and nitrogen cellular content are differently regulated, depending of the growth conditions.

    The Angelic Doctor and the Stagirite: Thomas Aquinas and Contemporary ,Aristotelian' Ethics

    PROCEEDINGS OF THE ARISTOTELIAN SOCIETY (HARDBACK), Issue 1 2001
    M. W. F. Stone
    To what extent, if any, is the moral thought of Thomas Aquinas ,Aristotelian'? This question is not simply of historical interest, since it directs our attention to those areas of contemporary English-speaking moral philosophy where Thomas is discussed. In some quarters there is a tendency to classify Thomas as a thinker in the ,Aristotelian tradition', and his debt to Aristotle is thought to be apparent in his remarks on moral reasoning and virtue. Nowhere is this tendency more evident than in discussions of Thomas by supporters of modern virtue ethics. In this paper, I will argue that the relationship of Thomas's ethics to Aristotle is much more complicated than these discussions assume. Despite the strong and interesting affinities that exist between the practical philosophies of Thomas and Aristotle, the sum total of their common features can never disguise nor dilute the profound differences that separate them. The paper will conclude with some suggestions as to how an appreciation of these differences can enable us to cast Thomas's remarks on virtue in a different light. [source]


    The use of generalizability theory to estimate data reliability in single-subject observational research

    PSYCHOLOGY IN THE SCHOOLS, Issue 5 2007
    Pui-Wa Lei
    Direct observation of behaviors is a data collection method customarily used in clinical and educational settings. Repeated measures and small samples are inherent characteristics of observational studies that pose challenges to the numerical estimation of reliability for observational data. In this article, we review some debates about the use of Generalizability Theory in estimating reliability of single-subject observational data. We propose that it could be used but under a clearly stated set of conditions. The conceptualization of facets and object of measurement for a common design of observational research is elucidated under a different light. We provide two numerical examples to illustrate the ideas. Limitations of using Generalizability Theory to estimate reliability of observational data are discussed. © 2007 Wiley Periodicals, Inc.
