  1. 1. Endemic and epidemic Streptococcus pyogenes strains : reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis

    Författare :Anders Österlund; Uppsala universitet; []
    Nyckelord :Medical sciences; Streptococcus pyogenes; epidemiology; invasive disease; recurrentpharyngotonsillitis; RAPD; intracellular; biopsy culture; tonsils; immunohistochemistry; electron microscopy; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : The bacterium Streptococcus pyogenes is a common human pathogen known to cause bothuncomplicated and severe infections. Epidemics of invasive disease caused by S. pyogenesserotype T1 were seen in the county of Uppsala, Sweden, in 19881989 and 1994. LÄS MER

  3. 2. Gonad development and male gametogenesis

    Författare :Christina Österlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Testicular and ovarian organogenesis involve a pathway of developmental genes which are differentially regulated in males and females. In mammals, sex determination is controlled by a dominant gene, SRY, located on the Y chromosome. LÄS MER

  4. 3. Applications of the DGT technique for measurements of anions and cations in natural waters

    Författare :Helene Österlund; Per Andersson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Since the toxicity and mobility of trace metals are related to the metals' speciation, robust methods for trace metal speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER

  5. 4. Further characterisation and applications of the diffusive gradients in thin films technique : In situ measurements of anions and cations in environmental waters

    Författare :Helene Österlund; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : As both the toxicity and the mobility of trace elements are related to chemical forms present, robust methods for element speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER

  7. 5. Estrogen receptor gene activity within the brain and the relation to psychiatric disorders : mapping and function

    Författare :Marie Österlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :steroid hormone; ER system; in situ hybridization; rnRNA; ER serotonin; depression; affective disorders;

    Sammanfattning : Estrogens have for a long time been known to regulate neuroendocrine functions in the central nervous system (CNS), primarily related to reproduction. In recent years estrogens have been found to also modulate many other brain functions, for example mood and cognition. LÄS MER
