  1. 21. Pharmacodynamics of Enzyme Induction and its Consequences for Substrate Elimination

    Författare :Mats O. Magnusson; Rikard Sandström; Mats Karlsson; Ulf Bredberg; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Enzyme induction; Time course; Turnover model; Mechanism-based; Modelling; NONMEM; Farmakokinetik Farmakoterapi;

    Sammanfattning : Enzyme induction is a process whereby a molecule enhances the expression of enzymes. If the affected enzymes are involved in the elimination of a drug, this may result in a drug interaction. Induction is therefore of major concern during drug development and in clinical practice.

  2. 22. Microdialysis as a tool in pharmacokinetic-pharmacodynamic studies investigating the brain distribution and effect delay of morphine and morphine-6-glucuronide

    Författare :Marcel René Bouw; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : The microdialysis technique was developed as a tool for studying the pharmacokinetic and pharmacodynamicrelationships of morphine and morphine-6-glucronide (M6G). Concentrations of unbound drug in blood andbrain were monitored in order to elucidate the origin of the observed delay in antinociceptive effect in rats. LÄS MER

  3. 23. Clinical Pharmacokinetics of the Antimalarial Artemisinin Based on Saliva Sampling

    Författare :Toufigh Gordi; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Artemisinin; pharmacokinetics; saliva; HPLC; pharmacodynamics; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Sammanfattning : Artemisinin is the parent compound of a novel family of antimalarials. Repetitive administrations of artemisinin to both healthy volunteers and malaria patients have been shown to result in decreased plasma concentrations of the compound, most probably due to an autoinduction of different CYP450 enzymes.

  4. 24. Surface expression using the AIDA autotransporter : Towards live vaccines and whole-cell biocatalysis

    Författare :Martin Gustavsson; Gen Larsson; Per Berglund; Andres Veide; Jan-Willem de Gier; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AIDA-autotransporter; Escherichia coli; live vaccines; surface expression;

    Sammanfattning : The area of surface expression has gathered a lot of interest from research groups all over the world and much work is performed in the area. Autotransporters have been used for surface expression in Gram-negative bacteria. LÄS MER

  5. 25. Radionuclide Production with PET Cyclotrons, Applications and Preclinical Experiments

    Författare :Jonathan Siikanen; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radionuclide production; Solid target; Water target; Cyclotron; PET; SPECT; 18F; 89Zr;

    Sammanfattning : Nuclear medicine is based on the radiotracer principle of George de Hevesy and the magic bullet concept by Ehrlich and focuses on the diagnosis, the treatment of diseases and the investigation of normal states within the human body using radiopharmaceuticals. A radiopharmaceutical is an atom or a chemical compound in which one or several atoms are replaced with a radionuclide. LÄS MER
