  1. 6. Picophytoplankton seasonal dynamics in the Baltic Sea

    Författare :Javier Alegria Zufía; Hanna Farnelid; Catherine Legrand; Nathan Ahlgren; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; picophytoplankton; Synechococcus; picoeukaryote; phycoerythrin; phycocyanin; ammonium; nitrate; 16S rDNA; flow cytometry; grazing; viral lysis; seasonality; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Picophytoplankton (15°C there was a preference for ammonium over nitrate. Clade A/B dominated the SYN community, except during summer at the coastal station when low nitrate and warm temperatures promoted S5.2 dominance. Grazing was observed to control SYN and PPE abundances and had an effect on the SYN community structure. LÄS MER

  3. 7. Viral dynamics and evolution following primary HIV-1 infection

    Författare :Annika C Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV-1; primary infection; diversity; divergence; env; gag; pol; viral load; RNA; DNA; resting CD4 T-lyrnphocytes; antiretroviral resistance; founder virus; latency; PCR; cloning; sequencing;

    Sammanfattning : The knowledge of the early events during primary HIV-1 infection (PER) is of great importance for the understanding of the pathogenesis of HIV-1. A major problem in studies on PHI is the limited amount of data accessible from the early time-points. LÄS MER

  4. 8. HIV-1/HCV co-infection : immunity and viral dynamics

    Författare :Karolin Falconer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human immunodeficiency virus-1 (HIV-1) and hepatitis C virus (HCV) are the agents behind two viral epidemics causing huge morbidity and mortality worldwide. HCV infection is a leading cause of end-stage liver disease. LÄS MER

  5. 9. Perinatal HIV-1 infection : aspects on clinical presentation, viral dynamics and epidemiology

    Författare :Lars Navér; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Perinatal; HIV-1 infection; disease progression; viral load; genetic subtype; coreceptor; mother-to-child transmission; epidemiology;

    Sammanfattning : During the last 20 years HIV-1 infection has changed from being an unknown disease to being a widespread pandemic, in some areas affecting a large proportion of the human population. Mother-to-child transmission (MTCT) is the predominant route of transmission in children, who thus become infected during a period when their immune system is immature and developing. LÄS MER

  7. 10. Viral respiratory tract infections in children

    Författare :Johan Hamrin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The most common infection in humans is viral respiratory tract infections which predominantly present as the ‘common cold’. In some circumstances however, respiratory viruses cause acute lower respiratory tract infections (RTIs) and due to the high absolute number of infection the contribution of these cases to total morbidity and mortality are substantial.
