    Sammanfattning : Red blood cell (RBC) and iron status biomarkers are commonly used in clinical diagnostics. However, interpretations of infant test results are inherently challenging. LÄS MER

  3. 2. Investigating the source of free fetal hemoglobin in preeclampsia. The role of the placenta and the fetus

    Författare :Zahra Masoumi; Lund Obstetrik och gynekologi; []
    Nyckelord :Preeclampsia pregnancy; Placenta; Umbilical cord blood; Fetal erythropoiesis; Non-erythroid globin;

    Sammanfattning : Preeclampsia (PE) is an important pregnancy complication that affects 3-8% of women worldwide and is a leading cause of maternal and fetal morbidity and mortality. It is known that PE is associated with placental dysfunction, resulting in hypoxia, oxidative stress, altered metabolism and production of inflammatory cytokines. LÄS MER

  4. 3. Clinical and immunological aspects of human parvovirus B19 infection

    Författare :Oscar Norbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human Parvovirus B19; intrauterine fetal death; hematopoiesis; bone marrow suppression; gamma-interferon; immune response; cytotoxic T cell; acute infection; persistent infection;

    Sammanfattning : Human parvovirus B19 (B19) causes erythema infectiosum, a limited disease of childhood also known as the fifth disease or slapped cheek syndrome, referring to the characteristic facial rash. It normally infects through the respiratory route, even though transmission via blood products and transplanted organs occur. LÄS MER

  5. 4. Human parvovirus B19 : studies on the pathogenesis of infection

    Författare :Thomas Tolfvenstam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human parvovirus B19 (B19) causes the common childhood disease erythema infectiosum. The virus is transmitted by the respiratory route, infects erythroid progenitor cells, and thereby inhibits erythropoiesis. The seroprevalence in the adult population is 50-70%, rising to over 80% among the elderly. LÄS MER

  7. 5. THE HYPOXIC HEMATOPOIETIC STEM CELL NICHE Consequences of Hypoxia-induced Transcription on Stem Cell Fate

    Författare :Matilda Rehn; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic Stem Cells; Stem Cell Niche; Hypoxia; Hypoxia-Inducible Factor; Vegfa.;

    Sammanfattning : Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. LÄS MER
