  2. 11. Conformational changes in Staphylococcus aureus' alpha-toxin : from water-soluble monomer to a transmembrane channel

    Author : Beatrix Vécsey Semjén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Staphylococcal alpha-toxin membrane-protein interaction pore formingtoxins.;

    Abstract : Alpha-toxin is secreted by Staphylococcus aureus as a soluble monomer that without further activation can oligomerize and form a transmembrane channel. One of the aims of the present work was to understand the underlying mechanisms of the membrane insertion process. READ MORE

  4. 12. α-Synuclein Fibril Formation and the Effects of Lipid Membranes

    Author : Ricardo Gaspar; Fysikalisk kemi; []

    Abstract : Amyloid protein aggregation results in major disturbances of cellular processes in humans. The most common amyloid-related disorders are Alzheimer´s disease and Parkinson´s disease. Parkinson´s disease is charaterized by the formation of protein-rich aggregates that are deposited in neurons, termed Lewy bodies and Lewy neurites. READ MORE

  6. 14. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Author : Nie Jun; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Abstract : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).

  7. 15. Novel methods to synthesize aliphatic polyesters of vivid architectures

    Author : Rajiv Srivastava; Ann-Christine Albertsson; Ronnie Palmgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyesters; 1; 5-dioxepan-2-one; Caprolactone; Sn Oct 2; Enzyme; Lipase-CA; Ring-Opening Polymerization; Architecture; Tissue Engineering; Polymer chemistry; Polymerkemi;

    Abstract : Cross-linked films of ε-caprolactone (CL) and 1,5-dioxepan-2-one (DXO) having various mole fractions of monomers and different cross-link densities were prepared using 2,2’-bis-(-caprolactone-4-yl) propane (BCP) as cross-linking agent and Sn(Oct)2 as catalyst. Reaction parameters were examined to optimize the film-forming conditions. READ MORE
