  2. 21. Structural enzymology of oxalate degradation in Oxalobacter formigenes

    Author : Catrine L Berthold; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Oxalic acid, as one of nature's most highly oxidised compounds, is toxic to most organisms. It is introduced in the human body in the diet but also as a waste product of cellular metabolism. Mammals do not posses the ability to degrade oxalate and must excrete it in the urine or through the intestine. READ MORE

  4. 22. Palladium Catalyzed Methane Oxidation for Emission Control

    Author : Ida Friberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water deactivation; methane oxidation; regeneration; Pd beta; Pd Al2O3; Si Al ratio; Ba; sulfur poisoning; Pd SSZ-13;

    Abstract : The use of methane based fuels, such as natural gas and biogas, benefits from lower emissions of CO2, CO, NOx, non-methane HC, SOx and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt CH4 residuals, which are desirable to minimize since CH4 is a strong greenhouse gas with high global warming potential. READ MORE

  5. 23. Predictive testing for contact allergy : comparison of some guinea pig and mouse protocols including dose-response designs

    Author : Helen Wahlkvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : contact allergens; contact allergy; cumulative contact enhancement test; dose-response; evaluation; Freund s complete adjuvant test; guinea pig maximization test; local lymph node assay; mouse ear swelling test; patch test; predictive testing; statistical analysis;

    Abstract : Contact allergy (delayed hypersensitivity) may develop as a result of skin exposure to contact allergens (haptens) and can lead to allergic contact dermatitis. The purpose of this study was to evaluate some predictive animal test methods for contact allergens. READ MORE
