  2. 1. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

    Author : Sara K. Olofsson; Otto Cars; Dan I. Andersson; Diarmaid Hughes; George G. Zhanel; Uppsala universitet; []
    Keywords : Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

    Abstract : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. READ MORE

  4. 2. Selection and use of affinity proteins developed by combinatorial engineering

    Author : Kristofer Sandström; KTH; []
    Keywords : phage display; combinatorial; selection; cd28; cllulosome; cellulose;

    Abstract : In affinity protein biotechnology the selective bindingbetween a chosen protein and an interacting biomolecule isutilized for a variety of applications including bioseparation,detection and therapy. Traditionally, affinity proteinsrecruited for such applications have been derived from naturalproteins or immunoglobulins generated via immunization routes. READ MORE

  5. 3. Pollen Competition as a Target for Sexual Selection in Plants

    Author : Åsa Lankinen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Pollen tube growth rate; Pollen selection models; Pollen interactions; Pollen competition; Plants; Phenotypic plasticity; Non-random mating; Genotype by environment interactions; Mate choice; Viola tricolor.; Plant ecology; Växtekologi;

    Abstract : According to the theory of sexual selection, traits can evolve because they confer a mating advantage in competition with members from the same sex. In animals, sexual selection is considered as an important evolutionary force. In this thesis I have investigated the potential for sexual selection in plants. READ MORE

  6. 4. Avian MHC: variation and selection in the wild

    Author : Helena Westerdahl; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymorphism; balancing selection; cDNA; avian malaria; great reed warbler; Djurekologi; bird; Animal ecology; immune defence; MHC class II; Major Histocompatibility Complex; MHC class I;

    Abstract : In vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. READ MORE

  7. 5. Life History of the Common Gull (Larus canus) : A Long-Term Individual-Based Study

    Author : Kalev Rattiste; Mats Björklund; Jon E Brommer; Jan-Åke Nilsson; Uppsala universitet; []
    Keywords : Ecology; longitudinal studies; reproductive success; survival; pair bond; indicator trait; breeding time; heritability; selection; Ekologi; Larus canus; ekologisk botanik; Ecological Botany;

    Abstract : An individual’s life history is a sequence of events which eventually determine its contribution to the next generation, or fitness. These events are affected by environmental factors, genetic make-up and decisions made by an individual and its breeding partner. READ MORE
