  1. 1. Aspects of chronic autoimmune thyroiditis in children and adolescents

    Detta är en avhandling från Institutionen för kliniska vetenskaper, Malmö

    Författare :Johan Svensson; Lunds universitet.; Lund University.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescents; thyroid autoantibodies; enterovirus infection; thyroid ultrasonography; reference standard; goiter; chronic autoimmune thyroiditis; levothyroxine treatment; Medicin människa och djur ; Medicine human and vertebrates ; children;

    Sammanfattning : The aims of this thesis were to 1) compare different methods for detection of antibodies against thyroglobulin (TgAb) and thyroid peroxidase (TPOAb), particulary in children with chronic autoimmune thyroditis (AIT), 2) investigate if maternal enterovirus infection is a risk factor for development of AIT in offspring, 3) ascertain the prevalence of thyroid autoantibodies in cord blood sera from children who later developed AIT, 4) develop a new reference standard for interpretation of normative thyroid volumes in Swedish children, and 5) evaluate the effect of Levothyroxine (L-thyroxine) treatment on thyroid size in children and adolescents with AIT. We found that 1) Methods based on radioimmunoassay (RIA) were more efficient in detecting both TgAb and TPOAb in children with AIT than methods based on agglutination. LÄS MER

  2. 2. Optical properties of some complex defects in silicon

    Detta är en avhandling från Linköping, Sweden : Department of Physics and Measurement Technology

    Författare :Johan Svensson; Linköpings universitet.; Linköpings universitet.; [1990]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : lnfrared absorption spectroscopy has been used study transitions between electronic states related to some complex defects in silicon. Three different defects have been studied: a complex defect involving carbon as one of its constituents, a divacancy, and a defect found in silicon containing tin. LÄS MER

  3. 3. Recombinant amelogenin - Strategies for purification and protein processing

    Detta är en avhandling från Linköping, Sweden : Department of Physics and Measurement Technology

    Författare :Johan Svensson Bonde; Lunds universitet.; Lund University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant amelogenin; protein purification; fusion protein; purification tag; enamel; hydroxyapatite; matrix protein; dental regeneration; wound healing; bone formation;

    Sammanfattning : Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. LÄS MER

  5. 5. Alcohol consumption and alcohol-related harm among young people: studies of the recent experience in Sweden

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Public Health Sciences

    Författare :Johan Svensson; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: The starting point for this thesis was the unexpected development in recent trends in youth drinking and harm in Sweden which seemed to question some basic assumptions of the total consumption model. For example, rapidly falling youth consumption and rising non-drinking rates were seen despite higher availability and increasing population drinking. LÄS MER
