  1. 16. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

    Författare :Susanna Gross; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

    Sammanfattning : Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. LÄS MER

  3. 17. Familial thoracic aortic aneurysms and dissections : studies on genotype and phenotype

    Författare :Matias Hannuksela; Bo Carlberg; Bengt Johansson; Eva-Lena Stattin; Anders Gottsäter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thoracic aorta; familial aortic aneurysm; familial aortic dissection; genetics; aortic stiffness;

    Sammanfattning : Background: Thoracic aortic aneurysms and dissections (TAAD) have a genetic component with an estimated 20-25% of the patients having a positive family history. An aneurysm often precedes a dissection. Acute aortic dissections are associated with high mortality and morbidity, even when operated on. LÄS MER

  4. 18. Studies on periodontitis and analyses of individuals at risk for periodontal diseases

    Författare :Henrik Jansson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; diabetes mellitus; genotype; periodontal disease; risk factor;

    Sammanfattning : Parodontit är en infektionssjukdom som orsakas av munhålans normala bakterieflora samt faktorer i infektionsförsvaret. Det inflammatoriska svaret fungerar som ett skydd för värden men är samtidigt vävnadsnedbrytande. Detta är anledningen till förlust av tandens stödjevävnader. LÄS MER

  5. 19. Gene transfer by interspecific hybridization in bryophytes

    Författare :Weerachon Sawangproh; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homozygote; heterozygote; admixture; single nucleotide polymorphism; STRUCTURE; PCoA; hybrid index; inbreeding; outbreeding; hybrid depression; heterosis; phylogeny; purging selection; genetic purging; genotype; phenotype; sympatry; allopatry;

    Sammanfattning : The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. LÄS MER

  7. 20. Genetical and Clinical Studies in Wilson's Disease

    Författare :Erik Waldenström; Kerstin Westermark; Ulf Landegren; Ann-Christine Syvänen; Peter Ferenci; Uppsala universitet; []
    Nyckelord :Internal medicine; copper radioisotopes; DNA sequence analyses; genotype; hepatolenticular degeneration; neoplasms; phenotype; positron-emission tomography; psychopathology; Invärtesmedicin;

    Sammanfattning : Wilson’s disease is a rare inborn error of metabolism caused by a defect in ATP7B, a protein necessary for proper copper excretion into bile. It is characterised by copper accumulation with hepatic and central nervous system dysfunction. LÄS MER
