  1. 1. Extraction and chromatography of bioactive compounds in complex samples using supercritical CO2 technology

    Författare :Said Alhamimi; Centrum för analys och syntes; []
    Nyckelord :Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

    Sammanfattning : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. LÄS MER

  2. 2. Evaluation of HIV testing strategies and monitoring of immune responses in HIV-vaccinated individuals in Tanzania

    Författare :Said Aboud; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : This thesis describes studies on the evaluation of human immunodeficiency virus (HIV) enzyme-linked immunosorbent assays (ELISAs) and simple rapid HIV assays for use in HIV testing strategies in resource-limited settings and studies of HIV vaccine-induced immune responses. Peripheral blood mononuclear cell (PBMC) preparation techniques were also studied in preparation for use in the HIV vaccine trials. LÄS MER

  3. 3. Rethinking land access governance in Global South Cities : understanding the dynamics and contentions of land access processes and governance mechanisms in peri-urban areas of Dar es Salaam, Tanzania

    Författare :Said Nuhu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The governance of land access is recognised as vital for peri-urban growth and development in the Global South Cities because it is important for accommodating urban expansion. Peri-urban areas attract multiple actors with diverging and conflicting interests and needs, contributing to land access dynamics and contentions. LÄS MER

  4. 4. Gallbladder and pancreatic disease in patients with primary sclerosing cholangitis

    Författare :Karouk Said; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Cholecystitis; gallbladder; ejection fraction; magnetic resonance imaging; pancreatic duct; chronic pancreatitis; thioredoxin; Immunohistochemical staining;

    Sammanfattning : The aims of this study were to assess the occurrence of gallbladder abnormalities and dysfunction, to evaluate clinically useful biomarkers for premalignancy and malignancy in gallbladder epithelium and to assess presence of pancreatic duct changes and early pancreatic abnormalities in patients with primary sclerosing cholangitis (PSC). In paper I and III we investigated presence of gallbladder abnormalities in 286 patients with PSC treated at Karolinska University Hospital, Huddinge, between 1970 and 2005. LÄS MER
