  1. 16. Inhibition of mPGES-1 as therapeutic strategy in inflammation and cancer

    Författare :Filip Bergqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Prostaglandin E2 (PGE2) is an inflammatory and oncogenic lipid mediator. It is mainly formed via metabolism of arachidonic acid by cyclooxygenases (COX-1 and COX-2) and the terminal enzyme microsomal prostaglandin E synthase-1 (mPGES-1). LÄS MER

  3. 17. NMR studies of metabolites and xenobiotics : From time-points to long-term metabolic regulation

    Författare :Ina Ehlers; Jürgen Schleucher; Farquhar Graham; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; isotopomer; phospholipid; persistent organic pollutant; CO2 fertilization; photorespiration;

    Sammanfattning : Chemical species carry information in two dimensions, in their concentrations and their isotopic signatures. The concentrations of metabolites or synthetic compounds describe the composition of a chemical or biological system, while isotopic signatures describe processes in the system by their reaction pathways, regulation, and responses to external stimuli.

  4. 18. Particle dynamics during biomass devolatilization : Momentum exchange and particle dispersion

    Författare :Angel David Garcia Llamas; Kentaro Umeki; Rikard Gebart; Per Gren; Peter Glarborg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; devolatilization; rocketing; PIV; PTV; Energiteknik; Energy Engineering;

    Sammanfattning : Devolatilization is a heat-driven thermochemical process in which a liquid or a solid fuel releases mass in the form of volatile compounds after drying, as a result of the combination of endothermic and exothermic reactions. It differs from pyrolysis in that it does not require an inert atmosphere and that the reactant must be either solid or liquid. LÄS MER

  5. 19. Active Matter in a Critical State: From passive building blocks to active molecules, engines, and active droplets

    Författare :Falko Schmidt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active matter; nonequilibrium; self-assembly; microswimmers; nanomotors; optical tweezers; colloidal molecules; active droplets; critical Casimir forces;

    Sammanfattning : The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able to develop mechanisms to generate active motion. LÄS MER

  7. 20. Immunoassays using high-Tc SQUIDs

    Författare :Fredrik Öisjöen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; YBCO; antigen.; magnetic nanoparticles; immunoassays; antibody; SQUID; High-Tc;

    Sammanfattning : The development of a system for immunoassays using highly sensitive high-Tc superconducting quantum interference devices (SQUIDs) and magnetic nanoparticles (MNPs) is described in this thesis.High-Tc SQUIDs were fabricated using pulsed laser deposition and photolithography.
