1. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence
Sammanfattning : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. LÄS MER
2. Clinical and experimental studies on oxidized fragrance terpenes as contact allergens
Sammanfattning : The work presented in this thesis aims to improve the possibilities for diagnosing contact allergy to oxidized limonene and linalool and to, in patients, study contact allergy from structurally closely related hydroperoxides with regard to their specificity, potency and cross-reactivity. The fragrance terpenes limonene (from citrus oil) and linalool (from lavender oil) are widely used in household and industrial products. LÄS MER
3. A novel fatty acid 8R-dioxygenase and hydroperoxide isomerase : catalytical, pharmacological and biochemical properties of two fungal enzymes
Sammanfattning : .... LÄS MER
4. Catalytic and Structural Properties of Heme-containing Fatty Acid Dioxygenases : Similarities of Fungal Dioxygenases and Cyclooxygenases
Sammanfattning : 7,8-Linoleate diol synthase (7,8-LDS) of the take-all pathogen of wheat, Gaeumannomyces graminis, converts linoleic acid to 8R-hydroperoxyoctadecadienoic acid (8-HPODE) by 8-dioxygenase activity (8-DOX), and further isomerizes the hydroperoxide to 7S,8S-dihydroxyoctadecadienoic acid (7,8-DiHODE) by hydroperoxide isomerase activity. Sequence alignment showed homology to prostaglandin H synthase (PGHS), and both enzymes share structural and catalytic properties. LÄS MER
5. Novel Fatty Acid Dioxygenases of Human and Plant Pathogenic Fungi : Studies by Gene Deletion and Expression
Sammanfattning : The dioxygenase-cytochrome P450 fusion proteins (DOX-CYP) comprise a heme-containing enzyme family that shares structural and catalytic properties with mammalian prostaglandin H (PGH) synthases. 7,8-Linoleate diol synthase (7,8-LDS) of Gaeumannomyces graminis was first characterized, and DOX-CYP enzymes are of mechanistic and biological interest.
