(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, 2021)The intrinsic dynamic nature of chromosomes is emerging as a fundamental component in regulating DNA transcription, replication, and damage-repair among other nuclear functions. With this increased awareness, reinforced ...
-
(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)The biogeochemical impact of coccolithophores is defined not only by their overall abundance in the oceans but also by wide ranges in physiological traits such as cell size, degree of calcification and carbon production ...
-
(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 ...
-
(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, 2021)Resolution of relationships at lower taxonomic levels is crucial for answering many evolutionary questions, and as such, sufficiently varied species representation is vital. This latter goal is not always achievable with ...
-
(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 ...
-
(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, 2020)Piptoporellus baudonii is proposed as a new combination for Laetiporus baudonii in the Polyporales (Basidiomycota) based on morphological and molecular features. This parasitic macrofungus attacks cashew trees, Eucalyptus, ...
