  2. 1. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Author : Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Abstract : 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. READ MORE

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

    Author : Vigdís Pétursdóttir; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Effects of Processing on Dietary Fibre in Vegetables

    Author : Maria Svanberg; Avdelningen för livsmedel och läkemedel; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Åsa Östlund; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Visualising Functional Nanostructures of Organic Semiconductors using Electron Microscopy

    Author : Gustav Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy; visualisation; clustering; molecular dopant; organic semiconductor; structure-property correlation; nanostructure; 3D; concentra- tion;

    Abstract : Organic semiconducting materials have enabled the solution-processable fabrication of light-weight and flexible electronic devices. In particular, doping using molecular dopants has enabled the fabrication of high-performance organic electronics. READ MORE
