  1. 21. Immunopathogenesis of relapsing fever borreliosis

    Författare :Marie Andersson; Sven Bergström; Betty P. Guo; Janis J. Weis; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Relapsing fever; Borrelia; mouse models; biological barriers; pathology; chemokines; cytokines; pregnancy; Molecular biology; Molekylärbiologi;

    Sammanfattning : Relapsing fever (RF) is caused by different species of Borrelia transmitted by soft ticks or by the human body louse. Illness is characterized by reappearing peaks of high concentrations of spirochetes in blood, concordant with fever peaks separated by asymptomatic periods. LÄS MER

  2. 22. Enterovirus Infections of β-Cells : A Mechanism of Induction of Type 1 Diabetes?

    Författare :Anna-Karin Berg; Gun Frisk; Torsten Tuvemo; Arne Andersson; Merja Roivainen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; enterovirus; type 1 diabetes; β-cells; human pancreatic islets; picornavirus; chemokines; nitric oxide; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : The process of β-cell destruction that leads to type 1 diabetes (T1D) is incompletely understood and it is believed to be a result of both genetic and environmental factors. Enterovirus (EV) infections of the β-cells have been proposed to be involved, however, the effects of EV infections on human β-cells have been little investigated. LÄS MER

  3. 23. Malaria during pregnancy and childhood : A focus on soluble mediators and neutrophils

    Författare :Stéphanie Boström; Marita Troye-Blomberg; Maria Yazdanbakhsh; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Plasmodium falciparum; pregnancy; childhood; neutrophils; biomarkers; cytokines; chemokines; antibodies; Fulani; Dogon; immunologi; Immunology;

    Sammanfattning : In areas where malaria is endemic, pregnant women and children bear the main burden of severe and life-threatening malarial disease. The aim of this work was to study the impact of Plasmodium falciparum infection on inflammatory responses in pregnant women and children residing in African countries. LÄS MER

  4. 24. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

    Författare :Ibrahim Elgali; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

    Sammanfattning : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

  5. 25. Studies of the Effect of Enterovirus Infection on Pancreatic Islet Cells

    Författare :Asma Basheir Elshebani; Gun Frisk; Heiki Hyöty; Uppsala universitet; []
    Nyckelord :Medical sciences; type 1 diabetes; Human pancreatic islets; β-cells; chemokines; enterovirus; MEDICIN OCH VÅRD;

    Sammanfattning : Enterovirus (EV) infections have been associated with the pathogenesis of Type 1 Diabetes (T1D). However, the pathway(s) by which EV may induce or accelerate diabetes is not well understood. LÄS MER
