  2. 1. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Author : Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. READ MORE

  4. 2. Regulatory properties of dendritic cells and B cells in adaptive immunity

    Author : Bengt Johansson Lindbom; Adaptivt immunförsvar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunologi; serologi; Immunology; Cellular differentiation; Cytokines; Dendritic cells; B lymphocytes; T lymphocytes;

    Abstract : This thesis is based upon four original papers in which human dendritic cells (DCs) and B cells have been analyzed in terms of how they influence the character of adaptive immune responses. DCs isolated from human tonsils were found to possess a capacity to directly regulate proliferation, isotype switching, and antibody production in B cells. READ MORE

  5. 3. The role of Malassezia in the pathogenesis of atopic eczema/dermatitis syndrome

    Author : Catharina Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Atopic dermatitis; atopic eczema dermatitis syndrome; Malassezia; Pityrosporum; T-cells; PBMC proliferation; cytokines; ELISPOT; TCRVB; IgE; skin prick test; atopy patch test;

    Abstract : Atopic eczema/dermatitis syndrome (AEDS) is a chronically relapsing skin disease, which is often associated with elevated levels of serum lgE. The immunopathology of AEDS is at present unclear, but it is known that lymphocytes infiltrating the AEDS lesions are predominantly of the CD4+ T helper phenotype. READ MORE

  6. 4. Barley- and Legume Products Beneficially Affect Metabolic Responses and Appetite Regulation

    Author : Elin Johansson; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The role of dietary fibre (DF) in disease prevention has been extensively investigated and prospective studies observed that increased DF intake decreased the risk of cardiovascular disease (CVD), reduced the risk of weight gain as well as the risk of type 2 diabetes (T2D). Also a diet characterized by low glycaemic index (GI) has been shown to reduce the risk of T2D and CVD. READ MORE

  7. 5. Activation of CO2 by Palladium Complexes Bearing Tridentate PCP Ligands

    Author : Roger Johansson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Kinetics; Insertion reactions; PCP ligands; CO2 activation; Palladium II complexes;

    Abstract : The present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. READ MORE
