  1. 1. Corticosteroids in Lumbar Disc Surgery

    Författare :Anders Lundin; Olle Nilsson; Björn Rydevik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; lumbar disc heniation; corticosteroids; outcome; thermal quantitative sensory testing; QST; VAS; disability rating index; DRI; microscopic discectomy; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : In a prospective randomised double-blind study eighty patients with MRI verified lumbar disc herniation and corresponding clinical findings underwent microscopic disc removal. The patients were peroperatively given systemic and local corticosteroids or placebo, and followed for 2 years. LÄS MER

  3. 2. Local Adaptation, Countergradient Variation and Ecological Genetics of Life-history Traits in Rana Temporaria

    Författare :Ane Timenes Laugen; Wolf Blanckenhorn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; amphibians; Bergmanns rule; body size clines; countergradient variation; developmental rate; FST; temperature; QST; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; populationsbiologi; Population Biology;

    Sammanfattning : The main aim of this work was to identify local adaptation processes in amphibian populations, thereby improving the general understanding of genetics and mechanisms behind the evolution and maintenance of biological diversity. Phenotypic and genetic variation in life-history traits was studied within and between populations common frog (Rana temporaria) populations along a 1600 km transect from southern Sweden to northern Finland.

  4. 3. Chronic intraoral pain - assessment of diagnostic methods and prognosis

    Författare :Maria Pigg; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuropathic pain; Orofacial pain; Trigeminal pain; Clinical studies; Prognosis; Diagnostic methods; Quantitative sensory testing; QST; Chronic pain; Endodontics;

    Sammanfattning : The overall goal of this thesis was to broaden our knowledge of chronic intraoral pain. The research questions were:•What methods can be used to differentiate inflammatory, odontogenic tooth pain from pain that presents as toothache but is non-odontogenic in origin?•What is the prognosis of chronic tooth pain of non-odontogenic origin, and which factors affect the prognosis?Atypical odontalgia (AO) is a relatively rare but severe and chronic pain condition affecting the dentoalveolar region.

  5. 4. Phenotypic plasticity and local adaptation in island populations of Rana temporaria

    Författare :Martin Lind; Frank Johansson; Juha Merilä; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Costs of plasticity; Developmental threshold; FST; Local adaptation; Phenotypic plasticity; Pool drying; QST; Freshwater ecology; Limnisk ekologi; zooekologi; Animal Ecology;

    Sammanfattning : Phenotypic plasticity is the ability of a genotype to express different phenotypes in different environments. Despite its common occurrence, few have investigated differences in plasticity between populations, the selection pressures responsible for it, and costs and constraints associated with it. LÄS MER

  7. 5. Tracing selection and adaptation along an environmental gradient in Populus tremula

    Författare :David Hall; Pär Ingvarsson; Thomas Bataillon; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Local adaptation; Selection; genetic differentiation; QST; FST; Association study; frequency spectra; recurrent hitchhiking; selective sweep; Tree; Populus; natural selection; quantitative genetics; Terrestrial ecology; Terrestrisk ekologi; Population Biology; populationsbiologi; genetik; Genetics;

    Sammanfattning : The distribution of the expressed genotype is moved around in the population over time byevolution. Natural selection is one of the forces that act on the phenotype to change the patterns ofnucleotide variation underlying those distributions. LÄS MER
