1. Ethers as gasoline additives : toxicokinetics and acute effects in humans
Sammanfattning : Ethers or other oxygen-containing compounds are used as replacements for lead in gasoline and to ensure complete combustion. Methyl tertiary-butyl ether (MTBE) is already in use world-wide and ethyl tertiary-butyl ether (ETBE) may be used increasingly in the future. LÄS MER
2. Expression of Manganese Lipoxygenase and Site-Directed Mutagenesis of Catalytically Important Amino Acids : Studies on Fatty Acid Dioxygenases
Sammanfattning : Polyunsaturated fatty acids can be bioactivated by two families of dioxygenases, which either contain non-heme iron (lipoxygenases) or heme (cyclooxygenases, linoleate diol synthases and α-dioxygenases).Lipoxygenases and their products play important roles in the pathophysiology of plants and fungi.

3. Lean NOx reduction with methanol over supported silver catalysts
Sammanfattning : The oxygen rich and relatively cold exhaust gases from fuel-efficient combustion engines bring challenges for the reductive aftertreatment of NOx. In this context selective catalytic reduction over silver/alumina has shown positive results, especially with oxygenated reducing agents. LÄS MER
4. Discovery of Novel Fatty Acid Dioxygenases and Cytochromes P450 : Mechanisms of Oxylipin Biosynthesis in Pathogenic Fungi
Sammanfattning : Dioxygenase-cytochrome P450 (DOX-CYP) fusion enzymes are present in diverse human and plant pathogenic fungi. They oxygenate fatty acids to lipid mediators which have regulatory functions in fungal development and toxin production. LÄS MER
5. Studies on 15-lipoxygenase in dendritic cells and leukotriene receptors in Hodgkin lymphoma
Sammanfattning : Classical Hodgkin lymphoma (cHL) is histologically characterized by a minority of malignant cells, the so-called Hodgkin-Reed Sternberg (H-RS) cells, surrounded by inflammatory cells such as T lymphocytes, eosinophils, macrophages and mast cells. It is generally believed that various molecules released by the H-RS cells are of major importance in the pathophysiology of cHL. LÄS MER
