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

    Författare :Johan Svensson; Karolinska Institutet.; Karolinska Institutet.; [2013]

    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

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

    Detta är en avhandling från Institutionen för kliniska vetenskaper, Malmö

    Författare :Johan Svensson; Lund University.; Lunds universitet.; [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

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

    Författare :Johan Svensson; Linköpings universitet.; Linköpings universitet.; [1990]

    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

  4. 4. 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; Lund University.; Lunds universitet.; [2008]
