  5. 3. Methodological aspects on microdialysis sampling and measurements

    Author : Pernilla Abrahamsson; Ola Winsö; Michael Haney; Anna-Maja Åberg; Urban Ungerstedt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microdialysis; liver ischemia; heart ischemia; epicardium; liver parenchyma; CMA 600; metabolism; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Abstract : Background:     The microdialysis (MD) technique is widely spread and used both experi­mentally and in clinical practice. The MD technique allows continuous collection of small molecules such as glucose, lactate, pyruvate and glycerol. Samples are often analysed using the CMA 600 analyser, an enzymatic and colorimetric analyser. READ MORE

  6. 4. Quantitative approaches for health risk assessment of environmental pollutants : estimation of differences in sensitivity, relative potencies, and margins of exposure

    Author : Fereshteh Kalantari; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Historically, quantitative health risk assessment of chemical substances is based on deterministic approaches. For a more realistic and informative health risk assessment, however, the variability and uncertainty inherent in measurements should be taken into consideration. READ MORE

  7. 5. Dose-response modeling : evaluation, application, and development of procedures for benchmark dose analysis in health risk assessment of chemical substances

    Author : Salomon Sand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Risk assessment; dose-response; benchmark; BMD;

    Abstract : In this thesis, dose-response modeling and procedures for benchmark dose (BMD) analysis in health risk assessment of chemical substances have been investigated. The BMD method has been proposed as an alternative to the NOAEL (no-observedadverse- effect-level) approach in health risk assessment of non-genotoxic agents. READ MORE
