  2. 1. Physiological changes in mice deficient in different subtypes of thyroid hormone receptors : a focus on studies of heart and muscle

    Author : Catarina Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : heart rate; ECG; body temperature; [beta]-adrenergic receptor density; thyroid hormone; isometric twitch; SERCa;

    Abstract : The aim of these studies was to determing the specific roles of the different subtypes of thyroid hormone receptors (TR), with focus on heart and muscle function, by using mice deficient in TR[alpha]1, TR[beta] (both TR[beta]1 and TR[beta]2 subtypes) and TR[alpha]1/[beta]. For this purpose, new techniques were set up to study various physiological parameters in these mice. READ MORE

  5. 3. Design and Synthesis of BACE-1 Inhibitors : Novel Compounds Targeting an Aspartic Protease Important in the Pathogenesis of Alzheimer’s Disease

    Author : Catarina Björklund; Bertil Samuelsson; Rolf Johansson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis deals with the design and synthesis of protease inhibitors targeting the aspartic protease BACE-1 (β-site APP cleaving enzyme-1), an enzyme important in the pathogenesis of Alzheimer’s disease. The inhibitors are evaluated with respect to inhibition data, in a structure-activity relationship part. READ MORE

  6. 4. Towards compatibilization of cellulose nanofibrils in polymer matrices : Polymer design for mediating the nanofibril–matrix interface

    Author : Rosella Telaretti Leggieri; Eva Malmström; Mats Johansson; Catarina de Carvalho Esteves; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibril CNF ; copolymer; nanocomposite; coating; reinforcement; interface; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Magnifying the nanostructure of wood reveals the features of an extraordinary nanocomposite material. In this nanocomposite, long fibrils of semicrystalline cellulose, with a cross-section in the nanometer range and length up to several micrometers, are embedded in an amorphous matrix made of other polymeric components.
