  1. 6. The construction, analysis and validation of mechanistic mathematical models of protein kinetics in the context of replicative ageing in budding yeast

    Författare :Johannes Borgqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein kinetics; Replicative ageing; Cdc42; Ordinary differential equations; Reaction diffusion models; Parameter estimation; Model validation; Model construction; Symmetry methods;

    Sammanfattning : Mathematical modelling constitutes a forceful tool for elucidating properties of biological systems. Using theoretical approaches in combination with experimental techniques it is possible to study specific molecular aspects of phenomena such as the ageing of human beings. LÄS MER

  3. 7. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

    Författare :Marlene Munoz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopolymers; polyhydroxyalkanoates; polyhydroxybutyrate; moderate halophile; Halomonas boliviensis; fermentation; recovery; thermally induced phase separation; scaffolds; covalent modification; hydrophobic ion pairing; polyethylenemine; lysozyme.;

    Sammanfattning : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. LÄS MER

  4. 8. The role of Malassezia allergens and mast cells in atopic eczema

    Författare :Christine Selander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atopic eczema (AE) is a chronic inflammatory skin disease, characterized by intense itching, dry skin, infiltration of immune cells and skin lesions. To date, the cause of AE, a disease affecting 15-30% of children and 2-10% of adults, remains unknown and the pathomechanisms are not fully understood. LÄS MER

  5. 9. Microarray Analysis of mRNA Decay Assays and Prediction of Drug Target Conservation

    Författare :Alexandra Jauhiainen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microarray analysis; mRNA decay; evolutionary conservation; ecotoxicology; environmental risk assessments; ecotoxicology;

    Sammanfattning : This thesis contains two papers concerning (I) the evolutionary conservation of drug targets and its potential use in environmental risk assessments and (II) mRNA degradation as a control mechanism during osmotic stress in the yeast S. cerevisiae. Environmental risk assessments are needed for the approval of new pharmaceutical compounds. LÄS MER

  7. 10. Halomonas species as a source of poly(3-hydroxybutyrate). Preparation of hydrophilic macroporous polymer scaffolds

    Författare :Daniel Guzmán; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Halomonas species; poly 3-hydroxybutyrate ; genome sequence; Fed-batch cultivation; macroporous scaffolds;

    Sammanfattning : This thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation. PHB is the simplest homopolymer belonging to the class of polyhydroxyalkanoates (PHAs), the biopolyesters that can biodegraded in the environment to carbon dioxide and water and are hence attractive substitutes for fossil-derived plastics.
