    Nyckelord :HIV; antiretroviral treatment; evolution; gag; pol; env;

    Sammanfattning : Due to the high replication rate and the low fidelity of the viral reverse transcriptase (RT), various mutations are introduced continuously into the gene pool of HIV-1. Together with recombination events this leads to the evolution of countless quasispecies. LÄS MER

  3. 22. Genetic factors influencing susceptibility to intracellular infections

    Författare :Fabio Sánchez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Genetic susceptibility; leprosy; leishmaniasis; HIV; quantitative trait locus; linkage analysis; multigenic; severity.;

    Sammanfattning : Genetics of susceptibility to infection is a complex trait in which many factors from the host, the parasite and the environment, interact to produce different clinical manifestations of disease. This thesis explores the relationship between the first infectious susceptibility gene ever cloned, SLC11A1 and the occurrence of intracellular infections (leprosy, leishmaniasis and HIV infection) in several populations of humans.

  4. 23. Factors influencing the success of pelagic cyanobacteria

    Författare :Per Hyenstrand; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; cyanobacteria; inorganic nitrogen; competition; iron; phytoplanktonsuccession; Biologi; Biology; Biologi; limnologi; Limnology;

    Sammanfattning : Cyanobacteria are present in most aquatic systems, and pelagic bloom-forming species often flourish in lakes. Since blooms of cyanobacteria are undesirable for several reasons, e.g. they can result in foul odours and tastes as well as toxicity, these organisms have been subject to an extensive amount of research around the globe.
