  2. 1. Exploring Electronic Processes at the Mesoporous TiO2/Dye/Electrolyte Interface

    Author : Wenxing Yang; Boschloo Gerrit; Hagfeldt Anders; Johansson Erik; Gerald Meyer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; dye regeneration; Stark effect; the local electric field; cationic effect;

    Abstract : Dye sensitized solar cells (DSSCs) are an attractive way to convert light into electricity. Its development requires a detailed understanding and kinetic optimization of various electronic processes, especially those occurring at the mesoporous TiO2/dye/electrolyte interface. READ MORE

  4. 2. Dendrimer-mediated gene delivery: Effect of polymer structure on cellular response

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene therapy; DNA condensation; cationic polymers; toxicity; non-viral vector; drug delivery; polyplex; PAMAM dendrimers;

    Abstract : The delivery of nucleic acids to cells, in vitro and in vivo, is becoming a realistic approach for intervention with gene expression at a molecular level. It can be used to repair malfunctioning genes or to introduce new functionalities, with the most important application being clinical treatment of human diseases. READ MORE

  5. 3. Adsorption kinetics of cationic polyacrylamides on cellulose fibres and its influence on fibre flocculation

    Author : Daniel Solberg; KTH; []
    Keywords : Adsorption; bridging; cationic polymers; cellulose fibres; electrosteric stabilisation flocculation; ;

    Abstract : The adsorption of cationic polyacrylamide (C-PAM) and silicananoparticles onto a model surface of silicon oxide wascompared with the adsorption of C-PAM to fibres and theirinfluence on flocculation of a fibre suspension. An increase inionic strength affects the polyelectrolyte adsorption indifferent ways for these two systems. READ MORE

  6. 4. NO Effect on Inflammatory Reaction in Extracorporeal Circulation : Ex vivo Studies

    Author : Mika Lahtinen; Jan Borowiec; Per Venge; Vibeke Videm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiac surgery; extracorporeal circulation; inflammatory reaction; NO; degranulation; neutrophil; eosinophil; basophil; complement; contact system; coagulation; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Clinical Chemistry; klinisk kemi;

    Abstract : Nitric oxide (NO) is expressed in inflammatory tissues. However, NO effects are controversial in inflammation; NO is described as acting in a dose dependent manner and possess both pro-inflammatory and anti-inflammatory properties. READ MORE

  7. 5. Development of lipodisks as carriers for cationic amphiphilic peptides

    Author : Karin Reijmar Brunnström; Katarina Edwards; Fredrik Höök; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Antibiotics have made a tremendous contribution to mankind. They are one of the most successful medicines in human history. However, more and more bacterial strains develop resistance and the risk to public health can hardly be overstated. New types of antibiotics are urgently needed. READ MORE
