    Sammanfattning : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. LÄS MER

  3. 2. Chemical analysis of complex mixtures with regard to potentially genotoxic organic compounds

    Författare :Tomas Alsberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes different methods for the extraction, fractionation, and analysis of particle adsorbed organic compounds. The utility of capillary gas chromatography mass spectrometry (GC-MS) for the analysis of polycyclic aromatic compounds (PAC) is demonstrated. LÄS MER

  4. 3. Prognostic and predictive factors for colorectal cancer

    Författare :Masoud Karimi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Colorectal cancer is the third most common cancer worldwide of which approximately 30% of cases are localized in the rectum. Rectal cancer accounts for around 700, 000 cases and 310, 000 deaths annually across the world with a global distribution that varies due to different lifestyles. LÄS MER

  5. 4. Understanding p53 structure and targeting mutant p53 for improved cancer therapy

    Författare :Qiang Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The p53 gene family consists of p53, p63 and p73. The three proteins share a high degree of structural similarity in their DNA-binding domains but have rather different functions. The tumor suppressor p53 acts as the guardian of the genome and is activated in response to cellular stress. LÄS MER

  7. 5. Design, synthesis and evaluation of spiro-bicyclo[2.2.2]octane derivatives as paclitaxel mimetics

    Författare :Sophie Manner; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric baker s yeast reduction; paclitaxel; spiro; bicyclo[2.2.2]octane; paclitaxel mimetics;

    Sammanfattning : Nature contains an endless supply of natural products and has for long been a source of inspiration for the pharmaceutical industry. Many of the drugs currently in clinical use originate from natural products. LÄS MER
