  1. 6. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Författare :Staffan Dryselius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER

  3. 7. Interaction of cyclotides and bacteria : A study of the cyclotide action and the bacterial reaction

    Författare :Sohaib Zafar Malik; Ulf Göransson; Dan Andersson; William Shafer; Uppsala universitet; []
    Nyckelord :Cyclotides; cycloviolacin O2; cycloviolacin O3; cycloviolacin O19; antimicrobial peptide resistance; Salmonella enterica; Eschericia coli; Viola odorata; Farmakognosi; Pharmacognosy;

    Sammanfattning : The growing problem of antibiotic resistance and the lack of promising prospective antibiotics have forced us to search for new classes of antibiotics. Among the candidates to develop into future antibacterials are antimicrobial peptides (AMPs). LÄS MER

  4. 8. Angiogenic growth factors : mechanism of action and function in vascular development

    Författare :Charlotte Rolny; Andrius Kazlauskas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; PDGF-BB; VEGF; angiogenesis; hypoxia; migration; heparin; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. LÄS MER

  5. 9. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    Författare :Veljo Sild; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. LÄS MER

  7. 10. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa

    Författare :Salme Timmusk; Gerhart Wagner; Janet Jansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Plant growth promotion; Induced resistance; Biocontrol; Deleterious rhizobacterium; Mikrobiologi; Microbiology; Mikrobiologi;

    Sammanfattning : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. LÄS MER
