  1. 6. Lactobacillus mediated delivery of therapeutic peptides in the gastrointestinal tract

    Författare :Yin Lin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Lactobacilli are normal residents of the human gastrointestinal (GI) tract. Many species belonging to the genera Lactobacillus with health beneficial properties have been introduced as probiotics. Genetic engineering of Lactobacillus could potentially combine the colonizing ability and probiotic effect with an engineered therapeutic function. LÄS MER

  3. 7. Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition

    Författare :Juan Pablo Almeida; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus;

    Sammanfattning : High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching. LÄS MER

  4. 8. Assembly Mechanisms in Aquatic Bacterial Communities : The Role of Disturbances, Dispersal and History

    Författare :Mercè Berga Quintana; Silke Langenheder; Eva Lindström; Örjan Östman; Mathew Leibold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; diversity; community composition; metacommunity;

    Sammanfattning : Environmental conditions, biotic interactions, dispersal and history have been suggested to be important processes influencing the spatial distribution of organisms and thus to affect community assembly. Understanding how these processes influence community assembly is important, particularly because community diversity and composition are suggested to be relevant for ecosystem functioning. LÄS MER

  5. 9. Bacterial Regulation of Peripheral Immunity : Mechanistic insights from lactobacilli and Staphylococcus aureus

    Författare :Manuel Mata Forsberg; Eva Sverremark-Ekström; Monika Brunner-Weinzierl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Immune regulation; Cytokines; T cells; gamma-delta T cells; MAIT cells; NK cells; Lactobacillus; Staphylococcus aureus; staphylococcal enterotoxins; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : There is a constant cross-talk between our immune system and the colonizing microbiota. The gut resident bacteria produce a broad range of molecules with regulatory activities in both local and distal tissues. Staphylococcus (S. LÄS MER

  7. 10. Evolutionary consequences of ecological interactions

    Författare :Etsuko Nonaka; Åke Brännström; Göran Englund; Richard Svanbäck; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptive dynamics; eco-evolutionary dynamics; ecological speciation; ecosystem; individual based; population dynamics; phenotypic plasticity; predator-prey; sexual selection;

    Sammanfattning : Eco-evolutionary dynamics integrates the reciprocal interactions betweenecology and evolution. These two branches of biology traditionally assumethe other as static for simplicity. However, increasing evidence shows thatthis simplification may not always hold because ecology and evolution canoperate in similar timescales. LÄS MER
