  1. 1. Nucleic acid analysis tools : Novel technologies and biomedical applications

    Författare :Iván Hernández-Neuta; Mats Nilsson; Frank Bier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic acid analysis; padlock probes; selector probes; rolling circle amplification; microfluidics; single-molecule detection; digital quantification; fluorescence microscopy; mobile phone microscopy; molecular diagnostics; virology; Biochemistry; biokemi;

    Sammanfattning : Nucleic acids are fundamental molecules of living organisms functioning essentially as the molecular information carriers of life. From how an organism is built to how it responds to external conditions, all of it, can be found in the form of nucleic acid sequences inside every single cell of every life form on earth. LÄS MER

  3. 2. Retinoid metabolism and signalling in vascular smooth muscle cells

    Författare :Pauline Ocaya; Allan Sirsjö; Andreas C. Gidlöf; William S. Blaner; Örebro universitet; []
    Nyckelord :all-trans Retinol; all-trans Retinoic acid; retinoid metabolism; proliferation; Vascular smooth muscle cells; CYP26; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

    Sammanfattning : Smooth muscle cells (SMCs) play a major role in cardiovascular diseases. In advanced atherosclerosis, blood flow is impaired due to reduced luminal diameter. Percutaneous vascular interventions, including balloon angioplasty and stent-application are commonly used for the re-establishment of luminal size and improvement of tissue perfusion. LÄS MER

  4. 3. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Författare :Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. LÄS MER

  5. 4. Wild plants can improve their rhizosphere chemistry in acid soils

    Författare :Marion Schöttelndreier; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; wild plants.; time pattern; soil heterogeneity; rhizotrons; rhizosphere; pH; oxalic acid; nutrient availability; malic acid; hydroponics; citric acid; 14C; biodegradation; acid soils; aluminium toxicity; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. LÄS MER

  7. 5. Aspects on wettability and surface composition of modified wood

    Författare :Lars-Elof Bryne; Ove Söderström; Charles R. Frihart; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wettability; contact angle; work of adhesion; Lewis acid-base; modified wood; Building engineering; Byggnadsteknik;

    Sammanfattning : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. LÄS MER
