  1. 1. Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems

    Författare :Stefanie Eriksson; Fysikalisk kemi; []
    Nyckelord :diffusion NMR; diffusion tensor; Microscopic anisotropy; q-MAS; exchange; liquid crystals; yeast cell suspensions;

    Sammanfattning : NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. LÄS MER

  3. 2. Main Circuits, Submodules, and Auxiliary Power Concepts for Converters in HVDC Grids

    Författare :Stefanie Heinig; Hans-Peter Nee; Staffan Norrga; Kalle Ilves; Rainer Marquardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ac–dc power conversion; energy storage; fault tolerance; HVDC converters; HVDC grid; isolated power supply; modular multilevel converter MMC ; power system faults; silicon carbide; submodules; voltage source converter VSC ; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In order to enable the massive introduction of renewable energies the need for high-voltage direct current (HVDC) grids is anticipated. Large, globally interconnected HVDC networks will likely be the most cost-efficient means to balance electricity demand and available generation. LÄS MER

  4. 3. Exosomes : immunomodulators in cancer and therapy

    Författare :Stefanie Hiltbrunner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Exosomes are nano-sized membrane vesicles derived from the late endosomal compartment. They are capable of transferring proteins, lipids and RNA between cells. B cell and dendritic cell (DC)-derived exosomes express major histocompatibility complex (MHC) class I and II, as well as costimulatory molecules (CD80/86) and can initiate T cell responses. LÄS MER

  5. 4. Biodiversity-ecosystem function in a willow biomass production system : tree productivity, litter decomposition and fungal community

    Författare :Stefanie Hoeber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The relationship between biodiversity and ecosystem function is an important issue in ecology. Stands of Salix (willow) are suitable model systems to study this relationship. Salix and other crops are mainly grown in monoculture in agricultural systems. LÄS MER

  7. 5. Structure-based Virtual Screening for Ligands of G Protein-coupled Receptors : Design of Allosteric and Dual-Target Modulators

    Författare :Stefanie Kampen; Jens Carlsson; Peter Kolb; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; Polypharmacology; Molecular Docking; Structure-based Drug Design; Parkinson’s Disease; Virtual Screening; Allosteric Modulators; Bioinformatics; Bioinformatik;

    Sammanfattning : G protein-coupled receptors (GPCRs) are integral membrane proteins responsible for signal transduction of extracellular stimuli into the cell. Because of their widespread distribution throughout the human body and important roles in physiological processes, GPCRs are prominent drug targets and approximately 34% of all approved drugs interact with members of this superfamily.
