  1. 16. Evolution of symbiotic lineages and the origin of new traits

    Författare :Daniel Tamarit; Siv G. E. Andersson; Lisa Klasson; Amparo Latorre; Julian Parkhill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; symbiosis; host-association; Lactobacillus; Bifidobacterium; Rhizobiales; Bartonella; honeybees; ants; codon usage bias; genome architecture; genome organization; gene transfer agent; evolutionary genomics; comparative genomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. LÄS MER

  3. 17. Chronic sorrow and quality of life in patients with multiple sclerosis

    Författare :Ann-Kristin Isaksson; Gerd Ahlström; Lars-Gunnar Gunnarsson; Siv Söderberg; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Multiple sclerosis; illness experience; diagnosis experience; impairment; health-related quality of life; subjective quality of life; immunological treatment; chronic sorrow; depression; managing chronic illness; content analysis; well-being; Caring sciences; Vårdvetenskap; Vårdvetenskap; Nursing Science;

    Sammanfattning : The overall aim of this thesis was to increase our understanding and knowledge of patients’ experiences of living with multiple sclerosis (MS). A mixed-method design was used, including both qualitative and quantitative methods. LÄS MER

  4. 18. A mobile app for self-management of urinary incontinence : treatment effect and user experience

    Författare :Ina Asklund; Eva Samuelsson; Malin Sjöström; Katarina Hamberg; Siv Mørkved; Umeå universitet; []
    Nyckelord :stress urinary incontinence; pelvic floor muscle training; mHealth; self-management; randomized controlled trial; qualitative research; ansträngningsinkontinens; bäckenbottenträning; mHealth; egenbehandling; randomiserad kontrollerad studie; kvalitativ forskning; family medicine; allmänmedicin;

    Sammanfattning : Background Urinary incontinence affects 25-45% of all women. The most common type is stress urinary incontinence, which is the leakage of urine on physical exertion. Pelvic floor muscle training is an effective first-line treatment for this condition but many women do not seek help from their ordinary health care service. LÄS MER

  5. 19. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Författare :Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Phylogenetics; Mitochondrial origin and Evolution; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.

  7. 20. Biological and Molecular Characteristics of Microorganism-Stimulated Defence Response in Lycopersicon esculentum –L

    Författare :Idress H. Attitalla; Siv Andersson; Sture Brishammar; Sadik Tuzun; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Phytophthora cryptogea; Fusarium oxysporum strain IMI 386351; Pseudomonas sp. strain MF30; plant defence; phylogenetic analysis; differentiation methods; Biologi; Biology; Biologi;

    Sammanfattning : Microorganisms, including two fungi, Phytophthora cryptogea and Fusarium oxysporum strain Fo-(IMI 386351), and one bacterium, Pesudomonas sp. strain MF30, were tested for their abilities to stimulate plant defence responses in tomato (Lycopersicon esculentum –L.) and to serve as effective biocontrol agents (Bs).
