    Sammanfattning : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. LÄS MER

  2. 2. Effects of Processing on Dietary Fibre in Vegetables

    Författare :Maria Svanberg; Institutionen för livsmedelsteknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low molecular weight carbohydrates; carrot cultivars; molecular weight distribution; viscosity; water-soluble polysaccharides; processing; Dietary fibre; vegetables; bulking capacity; rats; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Several beneficial effects have been connected with dietary fibre. Insoluble fibre has a good faecal bulking capacity, whereas soluble and viscous dietary fibre has been shown to have beneficial effects on carbohydrate and lipid metabolism. LÄS MER

  3. 3. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques

    Författare :Åsa Östlund; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR diffusometry; Dissolution of cellulose; Chemical shift imaging; Fiber hornification; Xylan; Molecular weight; Pore size distribution; Cryoporometry; Cellulose solution; 19F NMR; Gelation of cellulose; Self-diffusion; Pulsed field gradient NMR; TBAF DMSO; 1H NMR;

    Sammanfattning : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. LÄS MER

  4. 4. Giant cell arteritis. Epidemiological, morphological and molecular genetic studies

    Författare :Vigdís Pétursdóttir; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giant cell arteritis; temporal artery; aorta; epidemiology; atrophy; calcification; estrogen receptor a; morphometry; immunocytochemistry; Western blot; molecular genetics;

    Sammanfattning : Giant cell arteritis (GCA) is a chronic inflammatory disorder of unknown etiology, affecting large and medium-sized arteries, predominantly in postmenopausal women. Its pathogenesis is probably multifactorial. Several studies suggest that GCA is an antigen-driven disease. LÄS MER

  5. 5. Electrospinning Nanofibres from Cellulose Dissolved in Ionic Liquid

    Författare :Linda Härdelin; Chalmers University of Technology; []
    Nyckelord :dissolution; Electrospinning; molecular weight distribution.; cellulose; rheology; ionic liquids; nanofibres;

    Sammanfattning : This thesis investigates the electrospinning of cellulose nanofibres from ionic liquids. Cellulose nanofibres produced by an environmentally friendly process have the potential to replace synthetic nanofibres produced with volatile and harmful solvents. LÄS MER
