  1. 1. Return Migration from Sweden 1968-1996. A Longitudinal Analysis

    Författare :Martin Klinthäll; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transient migration; longitudinal analysis; Sweden; income performance; integration; refugee; immigrant; Migration; labor market; self-selection; Social and economic history; Ekonomisk och social historia;

    Sammanfattning : This book deals with return migration from Sweden in the period 1968-1996 to Chile, Germany, Greece, Iran, Poland, Turkey, United States and Yugoslavia, against the background of economic and political developments in Sweden and in the different source countries. An important question in the study regards whether return migrants deviate from other immigrants in terms of human capital characteristics and economic integration. LÄS MER

  3. 2. Injury-induced activation of vascular smooth muscle cells. Role of specific gene expression and intracellular signalling pathways

    Författare :Cecilia Lövdahl; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metalloproteinase; extracellular matrix; ERK1 2 signalling; migration; proliferation; injury; vessel wall; smooth muscle cell; Medicine human and vertebrates ; Medicin människa och djur ;

    Sammanfattning : Migration and proliferation of smooth muscle cells (SMC) are important events in the development of atherosclerosis and restenosis following angioplastic surgery. It is important to gain further knowledge about the mechanisms regulating SMC form and function in order to understand the underlying disease process. LÄS MER

  4. 3. Regulation of GRAF1 membrane sculpting function during cell movement

    Författare :Monika K. Francis; Richard Lundmark; Pekka Lappalainen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocytosis; migration; polarisation; tension; CLIC GEEC; GRAF1; Rho GTPase; Cdc42; Rab8; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. LÄS MER

  5. 4. Energy migration and charge formation in conjugated polymers

    Författare :Yuri Zaushitsyn; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance; relaxation; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; egenskaper elektriska; magnetiska och optiska ; supraledare; magnetisk resonans; spektroskopi; supraconductors; magnetic and optical properties; electrical; energy transfer; Physics; Fysik; Condensed matter:electronic structure; transient absorption spectroscopy; conjugated polymer; charge photogeneration;

    Sammanfattning : The main part of the thesis is concerned with charge photogeneration in conjugated polymers. MeLPPP and POMeOPT films were investigated by transient absorption spectroscopy using different excitation photon energies and light intensities with and without an external electric field. LÄS MER

  7. 5. Regulation of PKCalpha and the role of PKC in neuroblastoma cell migration

    Författare :Helena Stensman; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; oncology; cancerology; Cytologi; Medicin människa och djur ; Medicine human and vertebrates ; neuroblastoma; cell migration; intramolecular interactions; autophosphorylation; Protein kinase C; onkologi; cancer;

    Sammanfattning : Members of the protein kinase C (PKC) family of serine/threonine kinases play critical roles in cellular regulation. Depending on differences in regulation, PKCs can be divided into classical (alpha, betaI, betaII and gamma), novel (delta, epsilon, eta and theta) and atypical (zeta and iota/lambda) isoforms. LÄS MER
