  1. 1. Physical activity and breast cancer. Risk, survival and perceived energy

    Författare :Anna Johnsson; LUCC - Lunds universitets cancercentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; occupational sedentariness; Breast cancer; exercise;

    Sammanfattning : Background: Physical activity and avoidance of sedentariness do enhance health in women with breast cancer, and could even reduce the risk of developing the disease. One aim of this thesis was to elucidate the association between sedentariness and breast cancer risk in women as a whole, and then separately for those younger than 55 years old and those 55 years or older.

  2. 2. Characterization of Gcn5 histone acetyltransferase in Schizosaccharomyces pombe

    Författare :Anna Johnsson; Anthony Wright; Mattias Mannervik; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : The organisation of eukaryotic DNA into chromatin provides a natural barrier that prevents full access to the DNA thereby inhibiting events such as transcription, replication and repair. In order for these DNA-related events to occur, the chromatin needs to be modified by chromatin remodelling or, by reversible post-translational modifications. LÄS MER

  3. 3. Pharmacogenetics of human cytochrome P450 3A (CYP3A) enzymes

    Författare :Anna Westlind Johnsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : The cytochrome P450 3A (CYP3A) subfamily encompasses the most important CYP enzymes with respect to drug metabolism, in particular CYP3A4. responsible for the metabolism of a majority of drugs being metabolized in order to be excreted. LÄS MER

  4. 4. Tracking the fate of biocontrol microorganisms in the environment using intrinsic SCAR markers

    Författare :Anna-Ida Johnsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Biocontrol microorganisms can be used as an alternative to conventional chemical pesticides to control plant diseases. This thesis investigated the fate and behaviour of three microbial model control agents with effect against fungal pathogens in cropping systems, and the spread of one of the model strains in bioaerosols.

  5. 5. The Actin Filament System : Its Involvement in Cell Migration and Neurotransmitter Release

    Författare :Anna-Karin Johnsson; Roger Karlsson; Stéphane Gasman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Actin; Profilin; Synaptotagmin; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Sammanfattning : The microfilament system consists of actin filaments as the major component and is regulated by a number of actin binding proteins. It is juxtaposed to the plasma membrane where it forms a dense cortical weave from where it pervades into the cell interior. LÄS MER
