(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The major virulence factor of enterotoxigenic Escherichia coli is the heat-labile enterotoxin (LT), an AB5 toxin closely related to the cholera toxin. LT consists of six subunits, the catalytically active A-subunit and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Next generation sequencing of ribosomal DNA is increasingly used to assess the diversity and structure of microbial communities. Here we test the ability of 454 pyrosequencing to detect the number of species present, and ...
-
(Master thesis / Masteroppgave, 2019)The genus Cochlearia, together with its sister genus Ionopsidium Rchb., forms the tribe Cochlearieae, a rather small tribe which comprises about 30 taxa, which either x=6 or x=7 basic chromosome number. The x=6 series forms ...
-
A new method to quantify the accuracy of classification and spatial delineation in land cover mapsRestricted Access (Master thesis / Masteroppgave, 2018)Land cover maps provide spatial information on the physical cover of the earth. With increasing strain on natural resources, these maps enable knowledge-based nature management. Such maps represent a generalization of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Background Advances in sequencing technologies and bioinformatics have made the analysis of microbial communities almost routine. Nonetheless, the need remains to improve on the techniques used for gathering ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Atlantic cod (Gadus morhua) provides an interesting species for the study of host-microbe interactions because it lacks the MHC II complex that is involved in the presentation of extracellular pathogens. Nonetheless, little ...

A stainless-steel mortar, pestle and sleeve design for the efficient fragmentation of ancient bone (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Different types of milling equipment – such as oscillating ball mills, freezer mills, mortar and pestle – can be used to fragment ancient bone prior to DNA extraction. However, each of these tools is associated with practical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Background Multigenic diseases are often associated with protein complexes or interactions involved in the same pathway. We wanted to estimate to what extent this is true given a consolidated protein ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In animals, cellularization of a coenocyte is a specialized form of cytokinesis that results in the formation of a polarized epithelium during early embryonic development. It is characterized by coordinated assembly of an ...

Aberrant m6A regulation in Alkbh5 deficient mice results in increased DNA methylation and altered gene expressionRestricted Access (Master thesis / Masteroppgave, 2013)
-
(Master thesis / Masteroppgave, 2017)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Colored dissolved organic matter (CDOM) absorbs a substantial fraction of photosynthetically active radiation (PAR) in boreal lakes. However, few studies have systematically estimated how this light absorption influences ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)Bioaccumulation of sediment‐associated polychlorinated biphenyls (PCBs) was examined in Atlantic cod (Gadus morhua) through direct diffusion from the sediment (via the water phase) and through the food chain (dietary ...

Accumulation of the neonicotinoid insecticide clothianidin in bumblebees (Bombus terrestris)Restricted Access (Master thesis / Masteroppgave, 2019)
-
(Master thesis / Masteroppgave, 2014)
-
(Doctoral thesis / Doktoravhandling, 2018)The last few years have seen the arrival of new effective cancer therapies which is directed at the immune system rather than the cancer cells directly. One type of cancer immunotherapies is the so-called checkpoint ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)The multifunctional enzyme transglutaminase 2 (TG2) is the target of autoantibodies in the gluten-sensitive enteropathy celiac disease. In addition, the enzyme is responsible for deamidation of gluten peptides, which are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)How genomic selection enables species to adapt to divergent environments is a fundamental question in ecology and evolution. We investigated the genomic signatures of local adaptation in Atlantic cod (Gadus morhua L.) along ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Theoretical models suggest that sympatric speciation along environmental gradients might be common in nature. Here we present the first data-based model of evolutionary diversification along a continuous environmental ...
