  2. 11. Studies on phosphate ester cleavage and development of oligonucleotide based artificial nucleases (OBAN’s)

    Author : Hans Åström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Five different Oligonucleotide Based Artificial Nuclease (OBAN) systems have been synthesized. OBAN's may be regarded as a development of traditional antisense methodology where inhibition of gene expression can be achieved by hybridizing a synthetic oligonucleotide to natural mRNA and thus inhibiting further translation into protein products.

  4. 12. Use of Switchable Carbamate Surfactants for Design of Reversible Colouring of Cotton

    Author : Anna-Karin Hellström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cotton; pigment; textile colouring; de-colouring; switchable surfactant; carbamate;

    Abstract : Circularity of materials is a global need. However, recycling of cotton often requires many steps involving chemical or mechanical treatments. According to the waste hierarchy, reuse is a more environmentally benign approach than recycling, giving extended lifecycles with only limited processing of materials. READ MORE

  5. 13. Characterization of aluminum in environmental systems using X-ray absorption and vibrational spectroscopy : The importance of organic matter

    Author : Kristoffer Hagvall; Torbjörn Karlsson; Per Persson; Lars Lövgren; Dan Berggren Kleja; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The fate and behavior of many metals in the environment are highly dependent on interactions with natural organic matter (NOM), which is abundant in most soils and surface waters. The complexation with NOM can influence the speciation of the metals by affecting their hydrolysis and solubility. READ MORE

  6. 14. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength

    Author : Julie Durruty; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acid precipitation.; LignoBoost process; compressible filter cake; particle interactions; xylan; softwood lignin; constitutive relationships; local filtration properties; dead-end filtration;

    Abstract : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.

  7. 15. Structure-function studies of glutaredoxins and related oxidoreductases

    Author : Tobias Elgán; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Thiol-disulfide oxidoreductase; thioredoxin; Trx; glutaredoxin; Grx; protein disulfide oxidoreductase; PDO; -C-X-X-C-; specificity; conformational stability; ligandinduced stability; CD spectroscopy; redox potential;

    Abstract : The members of the ubiquitous group of thiol-disulfide oxidoreductases are characterized by a conserved tertiary structure, the thioredoxin (Trx) fold, and by having a consensus -C-X-X-C- active site sequence motif. By utilizing the active site cysteines, these proteins participate in redox reactions by catalyzing reversible disulfide oxidation and reduction. READ MORE
