  1. 1. Ligand binding and enzyme catalysis studied by molecular dynamics simulations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tomas Hansson; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; molecular dynamics simulation; free energy; linear response; drug design; empirical valence bond; HIV protease; protein tyrosine phosphatase; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Molecular dynamics simulations and free energy calculations can be applied to biomolecular systems to predict ligand binding affinities. Combined with hybrid quantum-classical potential energy surfaces, such computations can also be used to probe enzymatic catalysis mechanisms. LÄS MER

  2. 2. The effects of glucocorticoids on brown fat : physiological and molecular studies

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Ineke Luijten; Jan Nedergaard; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Brown adipose tissue (BAT) is the main site for non-shivering thermogenesis in most mammals. The BAT-specific uncoupling protein-1 (UCP1) uncouples substrate oxidation from ATP production and hereby decreases metabolic efficiency. LÄS MER

  3. 3. Towards molecular weight-dependent uses of kraft lignin

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ayumu Tagami; Mikael Lindström; Olena Sevastyanova; Anna Wistrand; Stefan Backa; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; successive solvent fractionation; molecular weight; structural analysis; thermal stability; heat capacity; antioxidant activity; methylene blue sorption; tunicate cellulose nanofiber-starch lignin composites films; film properties; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. LÄS MER

  4. 4. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Detta är en avhandling från Kuopio : Kuopio University Printing Office

    Författare :Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; [1993]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Sammanfattning : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. LÄS MER

  5. 5. Protein Interaction Studies with Low Molecular Weight Ligands Applications for Drug Discovery, Basic Research and Diagnostic Tool Design

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tony Christopeit; U.Helena Danielson; Danièle Altschuh; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, the interactions between different proteins and small ligands were characterized by surface plasmon resonance spectroscopy (SPR) and fluorescence resonance energy transfer (FRET) based assays.   For the C-reactive protein (CRP), a new type of artificial binder was identified which allows designing diagnostic assays superior to commonly used standard assays.
