1. 11. Interferon-Υ and interleukin-4 in health and disease : Studies on Borrelia infection, inflammatory polyneuropathies and normal pregnancy

   Författare :Christina Ekerfelt; Ann Kari Lefvert; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Background: The immune system needs stringent regulation in order to effectively eliminate infecting agents and, at the same time, protect the body from immunemediated tissue destruction. T cells have a major role in this regulation by secreting cytokines. LÄS MER

3. 12. Humoral and cellular immune response to Helicobacter pylori in Bangladeshi children and adults that may be related to protection

   Författare :Taufiqur Rahman Bhuiyan; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; Adults; Children; Birth cohort; Maternal antibodies; Serology; Th17; T cell; B cell; Developing country;

   Sammanfattning : Helicobacter pylori (Hp) colonizes the human gastric and duodenal mucosa and the infection may cause peptic ulcers and gastric adenocarcinoma. Half of the world’s population is infected with Hp with the highest prevalence in developing countries. LÄS MER

4. 13. Perinatal Risk Factors for Childhood Leukemia

   Författare :Estelle Naumburg; Eleni Petridou; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Childhood leukemia; infant leukemia; leukemia epidemiology; supplementary oxygen; perinatal risk factors; perinatal infection; prenatal ultrasound; prenatal x-ray; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

   Sammanfattning : The aim of the studies described in this thesis was to assess the association between certain perinatal factors and the risk of childhood lymphatic and myeloid leukemia and infant leukemia. The five studies presented were all conducted in Sweden as population-based case-control studies. LÄS MER

5. 14. Aspects of chronic autoimmune thyroiditis in children and adolescents

   Författare :Johan Svensson; Pediatrisk endokrinologi; []
   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

7. 15. Causes and consequences of blood parasite infections in birds

   Författare :Martin Stjernman; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; Djurfysiologi; Parasitologi människa och djur ; Parasitology human and animal ; maternal transfer; stabilising selection; parasite resistance; parasites; trade-off; cost of reproduction; Ficedula hypoleuca; pied flycatcher; Haemoproteus; blue tit; Parus caeruleus;

   Sammanfattning : Parasites are ubiquitous and can cause significant fitness reductions to their hosts. Therefore, selection for the evolution of host resistance should be strong. However, resistance may be costly and should be traded-off against other fitness related traits. LÄS MER
