(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In most mammalian cells, DNA replication occurs once, and only once between cell divisions. Replication initiation is a highly regulated process with redundant mechanisms that prevent errant initiation events. In lower ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Epigenetic observations are represented by the total number of reads from a given pool of cells and the number of methylated reads, making it reasonable to model this data by a binomial distribution. There are numerous ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Adaptive radiation is the diversification of species to different ecological niches and has repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of the largest and deepest lakes in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Bacillus anthracis , the causative agent of anthrax, is a considerable global health threat affecting wildlife, livestock, and the general public. In this study, whole‐genome sequence analysis of over 350 B. anthracis ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Capture and long-distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Pituitary endocrine cells fire action potentials (APs) to regulate their cytosolic Ca2+ concentration and hormone secretion rate. Depending on animal species, cell type, and biological conditions, pituitary APs are generated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Objectives We report a transcriptome acquisition for the bath sponge Spongia officinalis, a non-model marine organism that hosts rich symbiotic microbial communities. To this end, a pipeline was developed to efficiently ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Background Understanding the phylogenetic relationships among species is one of the main goals of systematic biology. Simultaneously, credible phylogenetic hypotheses are often the first requirement for ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The house sparrow is an important model species for studying physiological, ecological and evolutionary processes in wild populations. Here, we present a medium density, genome wide linkage map for house sparrow (Passer ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Plague continued to afflict Europe for more than five centuries after the Black Death. Yet, by the 17th century, the dynamics of plague had changed, leading to its slow decline in Western Europe over the subsequent 200 y, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The Gasterosteidae fish family hosts several species that are important models for eco-evolutionary, genetic and genomic research. In particular, a wealth of genetic and genomic data has been generated for the three-spined ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A characteristic feature of vertebrate cells is a Golgi ribbon consisting of multiple cisternal stacks connected into a single-copy organelle next to the centrosome. Despite numerous studies, the mechanisms that link the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Intravitreal injections of antibody-based biologics targeting vascular endothelial growth factor (VEGF) are highly effective and have markedly decreased the risk of visual impairment associated with prevalent retinal ...
-
A new method to quantify the accuracy of classification and spatial delineation in land cover maps (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, 2019)Many laboratory courses consist of short and seemingly unconnected individual laboratory exercises. To increase the course consistency, relevance, and student engagement, we have developed a research‐inspired and project‐based ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A wide range of species, including marine mammals, seabirds, birds of prey, fish and bivalves, were investigated for potential population health risks resulting from contemporary (post 2000) mercury (Hg) exposure, using ...
