  2. 1. Adaptive evolution in multidimensional trait spaces

    Author : Paula Vasconcelos; Claus Rüffler; Maria Servedio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive dynamics; mutidimensional trait spaces; evolutionary dynamics; disruptive selection; resource competition; diversification;

    Abstract : Negative frequency-dependent disruptive selection, which arises due to the interplay between organisms of a population and their environment, is an important element driving phenotypic diversification and even speciation. Such selection regime can result from frequency- and density-dependent interactions between the organisms and their environment, so that the fitness landscape itself changes as the population evolves.

  4. 2. Oligonucleotide Complexes with Cell-Penetrating Peptides : Structure, Binding, Translocation and Flux in Lipid Membranes

    Author : Luis Daniel Ferreira Vasconcelos; Ülo Langel; Tore Bengtsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; Large unilamellar vesicle; Membrane perturbation; Endosomal escape; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The ability of cell-penetrating peptides to cross plasma membranes has been explored for various applications, including the delivery of bioactive molecules to inhibit disease-causing cellular processes. The uptake mechanisms by which cell-penetrating peptides enter cells depend on the conditions, such as the cell line the concentration and the temperature. READ MORE

  5. 3. Effects of warming and browning on benthic and pelagic ecosystem components in shallow lakes

    Author : Francisco Rivera Vasconcelos; Sebastian Diehl; Jan Karlsson; Christopher T. Solomon; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; benthic; pelagic; algae; consumers; browning; warming; shallow lakes; food web; dissolved organic matter;

    Abstract : The majority of lakes on Earth are shallow, unproductive and located at high latitudes. These lakes are experiencing big changes due to climate change, where two environmental drivers operate simultaneously, browning and warming. How they affect lake ecosystems is not well understood.

  6. 4. Vaccine development strategies applied to the Plasmodium falciparum malaria antigen 332

    Author : Nina-Maria Vasconcelos; Klavs Berzins; Matti Sällberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; malaria; sub-unit vaccines; immunogenicity; antibody response; antigen Pf332; Immunology; Immunologi;

    Abstract : Malaria is one of the major infectious diseases in the world with regard to mortality and morbidity, and the development of a vaccine against the malaria parasite Plasmodium falciparum is considered of high priority. The aim of the work presented in this thesis was to develop and characterize recombinant vaccine constructs based on the P. READ MORE

  7. 5. Complexes of cell-penetrating peptides with oligonucleotides : Structure, binding and translocation in lipid membranes

    Author : Luis Daniel Ferreira Vasconcelos; Ülo Langel; William C. Wimley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; oligonucleotide; transfection; non-covalent complexes; membrane interaction; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The fundamental element of life known to man is the gene. The information contained in genes regulates all cellular functions, in health and disease. The ability to selectively alter genes or their transcript intermediates with designed molecular tools, as synthetic oligonucleotides, represents a paradigm shift in human medicine. READ MORE
