  1. 1. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

    Författare :Richard Karlsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; hypoxia.; forkhead; Akt PKB; Bcl-2; apoptosis; Flt3; FL; c-kit; KL; cytokines; Hematopoiesis; progenitor;

    Sammanfattning : Hematopoietic stem cells and progenitor cells are maintained in the bone marrow microenvironment, where factors including soluble and membrane-bound cytokines influence the processes of self-renewal, proliferation and differentiation. Two nonreduntant cytokines with effects on hematopoiesis, Kit Ligand (KL) and Flt3 Ligand (FL), signal via related tyrosine kinase receptors, c-kit and Flt3. LÄS MER

    Sammanfattning : The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM).

    Sammanfattning : Privacy mechanism design is an important research area and is receiving increased attention in recent years. This field focuses on addressing the challenge of revealing general data that might have correlations with sensitive information, all while protecting this sensitive information against unauthorized access.

    Sammanfattning : Increasing awareness of sustainable building materials has led to interest in enhancing the structural performance of engineered wood products. Wood is a sustainable, renewable material, and the increasing use of wood in construction contributes to its sustainability. LÄS MER

  7. 5. Från mål till måltid : Implementeringen av det politiska målet om 25 procent ekologisk mat i offentlig sektor år 2010– en fallstudie kring skolmaten i Växjö

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; policy implementation; institutional framework; organization; street level bureaucracy; organic food; sustainable development; Växjö; Human geography; Kulturgeografi;

    Sammanfattning : The purpose of this thesis is to investigate the implementation of a political aim – formulatedfrom a context of sustainable development. In 2006 both the Swedish national Parliament andthe municipality of Växjö (among others) stated that 25% of publically served food wouldstem from organic production by the end of 2010. LÄS MER
