  1. 1. Direct Thrombin Inhibitors in Treatment and Prevention of Venous Thromboembolism: Dose – Concentration – Response Relationships

    Författare :Marie Cullberg; Mats O. Karlsson; Ulf G. Eriksson; Nick H.G. Holford; Uppsala universitet; []

    Sammanfattning : For prevention and treatment of thrombotic diseases with an anticoagulant drug it is important that an adequate dose is given to avoid occurrence or recurrence of thrombosis, without increasing the risk of bleeding and other adverse events to unacceptable levels. The aim of this thesis was to develop mathematical models that describe the dose-concentration (pharmacokinetic) and concentration-response (pharmacodynamic) relationships of direct thrombin inhibitors, in order to estimate optimal dosages for treatment and long-term secondary prevention of venous thromboembolism (VTE).

  3. 2. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity

    Författare :Jorge Llano; Leif A. Eriksson; Ulf Ryde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; statistical mechanics; biophysical chemistry; interface; surface thermodynamics; bioelectrochemistry; ionizing radiation; radiation therapy; condensed matter; computational chemistry; nucleic acids; radiation damage; electrode potential; electronic transport; photochemistry; strand break; photodynamic action; cytostatic; solvation; solvated electron; absolute potential; chemical potential; Biologi; Biology; Biologi;

    Sammanfattning : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.

  4. 3. Mechanisms behind Cadmium-Induced Teratogenicity

    Författare :Estíbaliz López Fernández de Villaverde; Lennart Dencker; Ulf Eriksson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Cadmium; Teratogenesis; Exencephaly; Mechanisms; Toxikologi; Toxicology; Toxikologi;

    Sammanfattning : Heavy metals polluting our environment cause concern for developing organisms. Among them, cadmium with extremely slow elimination from the body, causes lower birth weight in humans but has not been classify as a human teratogen. Studies in different laboratory animals have shown that cadmium indeed is a potent teratogen. LÄS MER

  5. 4. In vivo Pharmacokinetics of Two New Thrombin Inhibitor Prodrugs : Emphasis on Intestinal and Hepatobiliary Disposition and the Influence of Interacting Drugs

    Författare :Elin Matsson; Hans Lennernäs; Lars Knutson; Ulf Eriksson; Kim Brouwer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Direct thrombin inhibitors; prodrugs; ximelagatran; AZD0837; erythromycin; ketoconazole; drug-drug interactions; hepatobiliary transport; biliary clearance; ATP-binding cassette; ABC transporters; solute carriers; SLC transporters; CYP3A4; Biopharmacy; Biofarmaci; Biopharmaceutics; Biofarmaci;

    Sammanfattning : Biliary excretion is an important elimination route for many drugs and metabolites. For such compounds, it is important to know the extent of excretion and drug exposure in the bile, e.g., for the risk assessment of drug interactions, liver toxicity and the effects of genetic variants.
