  2. 1. The in vivo metabolism of Benzo(a)pyrene studied by chromatography in combination with mass spectrometry

    Author : Yang Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Polycyclic aromatic hydrocarbons (PAHs) constitute a large class of chemicals with widespread occurrence in the environment. It is essentially impossible to avoid exposure to these substances on a daily basis. READ MORE

  4. 2. Hemocompatibility of materials for use in prosthetic heart valves

    Author : Yanqi Yang; Eric G. Butchart; Linköpings universitet; []
    Keywords : Heart valve prosthesis; mechanical heart valves; bioprosthetic heart valves; biomaterials; hemocompatibility; blood-material interaction; in vivo test; MEDICINE; MEDICIN;

    Abstract : Thromboembolism (valve thrombosis and systemic embolism) is the main drawback of mechanical heart valve prostheses. The patients carrying these valves have to be subjected to life-long anticoagulant therapy to reduce thromboembolism. READ MORE

  5. 3. Asymmetric Synthesis and Mechanistic Insights of Transition-Metal-Catalyzed Hydrogenation

    Author : Jianping Yang; Pher G. Andersson; Clément Mazet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asymmetric hydrogenation; Iridium catalysis; Rhodium catalysis; Chiral organofluorine; Enantioconvergent catalysis; Arene hydrogenation; Organic Chemistry; organisk kemi;

    Abstract : The work presented in this thesis is focused on asymmetric synthesis and mechanistic insights of hydrogenations catalyzed by Ir-N,P- and Rh-diphosphine complexes. The developed methodologies provide an efficient catalytic system to access optically enriched compounds by exploiting the effect of the N,P ligand structure and investigating the enantioconvergent behavior.

  6. 4. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes

    Author : Qiancheng Xie; Staffan Lundström; James Yang; J. Gunnar I. Hellström; Anders G. Andersson; Nils Ruther; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial river; Sediment transport; Morphological change; Meandering; Confluence-diffluence; River training; Field measurements; Numerical simulations; Physical model tests; Machine learning; Alluvial flod; Sedimenttransport; Morfologisk förändring; Slingrande; Konfluens-diffluens; Flodträning; Fältmätningar; Numeriska simuleringar; Fysiska modellprov; Maskininlärning; Strömningslära; Fluid Mechanics;

    Abstract : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. READ MORE

  7. 5. Structural and Biochemical Studies of Antibiotic Resistance and Ribosomal Frameshifting

    Author : Yang Chen; Maria Selmer; Dominique Fourmy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein synthesis; elongation; elongation factor G; fusidic acid; antibiotic resistance; aminoglycoside adenyltransferase; ribosomal frameshifting; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : Protein synthesis, translation, performed by the ribosome, is a fundamental process of life and one of the main targets of antibacterial drugs. This thesis provides structural and biochemical understanding of three aspects of bacterial translation.Elongation factor G (EF-G) is the target for the antibiotic fusidic acid (FA). READ MORE
