  1. 16. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins

    Författare :Martin Lidman; Gerhard Gröbner; Magnus Wolf-Watz; Philip Williamson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bax; Bc-2; apoptosis; mitochondria; membranes; oxidized lipids; NMR; calorimetry; circular dichroism; biokemi; Biochemistry; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. LÄS MER

  5. 19. Functional hybrid and composite porous membranes derived from imidazolium-type poly(ionic liquid)

    Författare :Atefeh Khorsand Kheirabad; Jiayin Yuan; Naser Tavajohi Hassan Kiadeh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly ionic liquid ; porous polyelectrolyte membranes; composite materials; functional membranes; materialkemi; Materials Chemistry;

    Sammanfattning : Poly(ionic liquid)s (PIL)s, as a subclass of polyelectrolytes, are composed of polymeric backbones with ionic liquid (IL)-based species in each repeating unit. Recent studies have deepened the understanding of the PIL concept in terms of characteristics, functions and applications in comparison to classical ILs and traditional polyelectrolytes. LÄS MER

  7. 20. Proton transfer across and along biological membranes

    Författare :Johan Berg; Peter Brzezinski; Artur Osyczka; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological membranes; cardiolipin; cytochrome bo3; cytochrome c oxidase; energy conversion; fluorescence correlation spectroscopy FCS ; localized coupling; mitochondria; proton transfer; Rcf1; respiration; single-enzyme measurement; Biochemistry; biokemi;

    Sammanfattning : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. LÄS MER
