    Abstract : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bio­availability and environmental transport of the POPs. READ MORE

  4. 2. Studies of second coordination sphere effects and metal variations on [FeFe]-hydrogenase mimics

    Author : Holly J. Redman; Gustav Berggren; Pickett Chris; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogenases; synthesis; inorganic chemistry; molecular biomimetics; spectroscopy; FTIR; cyclic voltammetry; catalysis; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Abstract : Mitigation of climate change motivates researchers to explore hydrogen as a potential energy carrier. Unfortunately, widespread use of hydrogen as an energy carrier is limited by numerous challenges in its production, including high energy consumption; high economic cost; current reliance on rare metals such as platinum.

  5. 3. The Structural Basis of the Control of Actin Dynamics by the Gelsolin Superfamily Proteins

    Author : Sakesit Chumnarnsilpa; Robert Robinson; Lars Backman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Rearrangement of the actin cytoskeleton occurs in a variety of cellular processes and structures and involves a wide spectrum of proteins. Among these, the gelsolin superfamily proteins (GSPs) control actin organization by severing filaments, capping filament ends and bundling filaments. READ MORE

  7. 5. Design and synthesis of aspartyl protease inhibitors : Targeting HIV-1 and malaria plasmepsin I and II

    Author : Daniel Nöteberg; Charles Hedgecock; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Medicine; medicin;

    Abstract : Aspartyl proteases can generally be inhibited by peptide mimics containing an uncleavable peptide bond isostere at the proposed cleavage site. One such peptide bond isostere is the hydroxyethylamine moiety, which in this thesis has successfully been incorporated in potential inhibitors of the HIV-1-protease as well as the malarial proteases plasmepsin I and II.
