  1. 6. Learning System Thinking : The role of semiotic and cognitive resources

    Författare :Maria Larsson; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; systems thinking; collaborative modeling; learning; external representations; cognition; semiotics; system dynamics;

    Sammanfattning : In the course of our educational life we are introduced to various subject areas, each with its specific way of representing knowledge. The challenge for the learner is to be able to think in ways that are supported by, and match, the representational format. A fundamental question for the science of learning concerns how this is achieved. LÄS MER

  4. 8. Translational Aspects of Erythropoietin Receptor and Hypoxia-Inducible Factors in Breast Cancer

    Författare :Anna-Maria Larsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; Anemia; Hypoxia; Erythropoietin EPO ; EPO receptor EPOR ; Estrogen Receptor ER ; Hypoxia-Inducible Factors HIFs ; Tamoxifen Response; Proliferation;

    Sammanfattning : The main function of erythropoietin (EPO) is in hematopoiesis where EPO stimulates increased proliferation, survival and differentiation of erythrocytic precursors in response to hypoxia. The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. LÄS MER
