  1. 16. Mast cells in Hodgkin lymphoma : or 'What's a nice cell like you doing in a tumour like this?'

    Författare :Marie Fischer; Gunnar Nilsson; Gunilla Enblad; Tor Olofsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Hodgkin lymphoma; mast cells; CD30; CD30L; IL-9; CCL5; atopic dermatitis; psoriasis; IL-8; Patologi; Pathology; Patologi;

    Sammanfattning : Mast cell (MC) accumulation around tumours is an old observation gaining new relevance due to the multifaceted nature of MCs and their many roles in immunity, beyond allergy. Knowledge about tumour specific recruitment of, and interactions with, MCs is needed to unravel the function of their presence. LÄS MER

  3. 17. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests

    Författare :Kristoffer Hylander; Christer Nilsson; Bengt Gunnar Jonsson; Ellen Macdonald; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; boreal forest; bryophyte; buffer strip; ecological boundary; edge effect; headwater stream; land snail; liverwort; moss; phytometer; riparian forest; substrate; terrestrial gastropod; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. LÄS MER

  4. 18. iLocks: a novel tool for RNA assays with improved specificity

    Författare :Tomasz Krzywkowski; Mats Nilsson; Gunnar von Heijne; Weng-Onn Lui; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; miRNA; non-coding RNA; padlock probes; rolling circle amplification; invader; single cell; in situ; adenovirus; virology; diagnostics; Biochemistry; biokemi;

    Sammanfattning : The Central Dogma of molecular biology describes a framework for how genetic information is transferred in cells, placing RNA as a messenger between DNA and translated proteins. During the last years, interest in RNA research has grown tremendously due to the increasing understanding and recognition of the importance of RNA in regulation of gene expression, biochemical catalysis, and genome integrity surveillance.

  5. 19. Fatigue crack growth experiments and analyses - from small scale to large scale yielding at constant and variable amplitude loading

    Författare :Pär Ljustell; Fred L. Nilsson; Bo Alfredsson; Gunnar Härkegård; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fracture mechanics; fatigue crack growth; finite elements analysis; small scale yielding SSY ; large scale yielding LSY ; low cycle fatigue LCF ; crack tip opening displacement CTOD ; crack closure; potential drop method; constant amplitude load; variable amplitude load; inconel 718; stainless steel 316L;

    Sammanfattning : This thesis is on fatigue crack growth experiments and assessments of fatigue crack growth rates. Both constant and variable amplitude loads in two different materials are considered; a nickel based super-alloy Inconel 718 and a stainless steel 316L. LÄS MER

  7. 20. Incidental Gallbladder Cancer : Incidence, predictors, management and outcome in a Swedish population

    Författare :Linda Lundgren; Per A Sandström; Axel Ros; Gunnar Persson; Oliver Gimm; Magnus Nilsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Cholecystectomy is a common surgical procedure and incidental gallbladder cancer is a rare and unexpected finding at a cholecystectomy performed upon benign indications. Whether to perform routine or selective histopathology of the gallbladder specimen is still a subject for discussion. LÄS MER
