  1. 1. Mechanisms involved in amyloid induced cytotoxicity

    Författare :Johan Östman; Lars Lannfelt; Umeå universitet; []
    Nyckelord :amyloid; transthyretin; cytotoxicity; apoptosis; caspases; aggregation; molekylärbiologi; Molecular Biology;

    Sammanfattning : Amyloidoses comprise a group of diseases where normal or mutated protein precipitates into amyloid fibrils. The deposition of fibrils causes dysfunction of organs and toxicity to nervous tissue. Up to date, 24 different proteins and peptides are known to be able to form amyloid fibrils. LÄS MER

  2. 2. Structural studies of heterogeneous amyloid species of lysozymes and de novo protein albebetin and their cytotoxicity

    Författare :Vladimir Zamotin; Ludmilla Morozova-Roche; Daniel Otzen; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amyloid; cytotoxicity; atomic force microscopy; Biophysics; Biofysik;

    Sammanfattning : A number of diseases are linked to protein folding problems which lead to the deposition of insoluble protein plaques in the brain or other organs. These diseases include prion diseases such as Creutzfeld-Jakob disease, Alzheimer's disease, Parkinson's disease and type II (non-insulin dependent) diabetes. LÄS MER

  3. 3. Selenium cytotoxicity in cancer

    Författare :Marita Wallenberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Selenium is an essential trace element, present in the 21st amino acid selenocysteine, which is specifically incorporated into selenoproteins. Today, there are 25 identified selenoproteins in humans, whereof many comprises redox active functions to uphold the intracellular redox balance. LÄS MER

  4. 4. Cytotoxic Compounds of Plant Origin – Biological and Chemical Diversity

    Författare :Petra Lindholm; Anders Backlund; Lars Bohlin; Kristín Ingólfsdóttir; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacognosy; pharmacognosy; cytotoxicity; antitumour; Nuphar alkaloid; cyclotide; thionin; cardiac glycoside; Farmakognosi; Pharmacognosy; Farmakognosi;

    Sammanfattning : The development of resistance by tumour cells to chemotherapeutic agents is a major problem in cancer treatments. One way to counter this is to find compounds with cytotoxic mechanisms other than those of drugs in clinical use today. LÄS MER

  5. 5. Antiparasitic metabolites from plants used in the Tacana Bolivian native tribe : Traditional medicine, an overview of natural products with medicinal interest

    Författare :Ivan Limachi; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tacana Traditional Medicine; Antiparasitic; cytotoxicity; Hyptis brevipes; hyptis mutabilis; Tessaria integrifolia; Trichilia adolfi;

    Sammanfattning : The thesis aims to contribute to the preservation of traditional medicinal knowledge of the Tacana Bolivian native tribe, as well as to the isolation and characterization of antiparasitic metabolites from plants used for the treatment of endemic diseases. A selection of medicinal plants, made in collaboration with the Tacana communities who decided which plants have a specific medicinal propose, were collected and identified by the national herbarium of Bolivia, and confirmed by healers from the most representative communities.
