(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Patients with head and neck cancer (HNC) and patients with primary Sjögren’s syndrome (pSS) may exhibit similar symptoms of dry mouth and dry eyes, as a result of radiotherapy (RT) or a consequence of disease progression. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The aim of the present study was to investigate effects of defined mixtures of polycyclic aromatic hydrocarbons (PAHs) and perfluoroalkyl substances (PFASs), at low, environmentally relevant (1× = L), or high (20× = H) ...

A proteomics-based approach to identify interactors of the IDA-HAE/HSL2 signaling pathwayRestricted Access (Master thesis / Masteroppgave, 2019)
-
Protist diversity across a marine - freshwater gradient with a special focus on the X-cell parasiteRestricted Access (Master thesis / Masteroppgave, 2014)Protists are a highly abundant and diverse group of microorganisms that hold important ecological roles in all aquatic ecosystems. Phototrophic protists are responsible for a large portion of the global primary production, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Protist community composition and seasonal dynamics are of major importance for the production of higher trophic levels, such as zooplankton and fish. Our aim was to reveal how the protist community in the Skagerrak changes ...

Protists in the intestinal content of Atlantic cod (Gadus morhua L.), with a special emphasis on two parasite groups; the X-cell and Mesomycetozoa.Restricted Access (Master thesis / Masteroppgave, 2015)Protists have representatives in all but one of the kingdoms in the tree of life and are highly important in the oceans, where they generate most of the carbon-flow in the first trophic levels. Parasitic lineages work as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Extracellular vesicles (EVs) are membrane-bound particles released from cells, and their cargo can alter the function of recipient cells. EVs from X-irradiated cells have been shown to play a likely role in non-targeted ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The ALKBH family of Fe(II) and 2-oxoglutarate dependent oxygenases comprises enzymes that display sequence homology to AlkB from E. coli, a DNA repair enzyme that uses an oxidative mechanism to dealkylate methyl and etheno ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The Notch signalling pathway is a conserved and widespread signalling paradigm, and its misregulation has been implicated in numerous disorders, including cancer. The output of Notch signalling depends on the nuclear ...
-
(Master thesis / Masteroppgave, 2015)Flavohemoglobin is a flavoheme enzyme that catalyzes dioxygenation of nitric oxide (NO) to nitrate NO3–. NO is diatomic radical gas produced by enzymatic and non-enzymatic oxidation of reduced nitrogenous compounds. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Lactobacillus plantarum produces a number of antimicrobial peptides (bacteriocins) that mostly target closely related bacteria. Although bacteriocins are important for the ecology of these bacteria, very little is known ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Enteric redmouth disease caused by the pathogen Yersinia ruckeri is a significant problem for fish farming around the world. Despite its importance, only a few virulence factors of Y. ruckeri have been identified and studied ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)1. An increasing number of empirical studies aim to quantify individual variation in demographic parameters because these patterns are key for evolutionary and ecological processes. Advanced approaches to estimate individual ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Copepods are a critical component of ocean ecosystems, providing an important link between phytoplankton and higher trophic levels as well as regulating biogeochemical cycles of carbon (C) and nutrients. Lipid-rich animals ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Although artificial-selection experiments seem well suited to testing our ability to predict evolution, the correspondence between predicted and observed responses is often ambiguous due to the lack of uncertainty estimates. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)1. Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding ecology of these apex predators remains ...
-
(Master thesis / Masteroppgave, 2014)Aberrant DNA methylation is one of the most common alterations in cancer, and a vast diversity of methods for its investigation exists. Quantitative methylation-specific PCR (qMSP) is frequently used to estimate the amounts ...
-
(Master thesis / Masteroppgave, 2022)In the present study, the temporal and spatial paleoecology of the Lower Silurian Rytteråker Formation in the Oslo region, is explored through multivariate gradient analysis of a novel dataset of stratigraphically collected ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)An accurate method to estimate the age of a stain or the time since deposition (TsD) would represent an important tool in police investigations for evaluating the true relevance of a stain. In this study, two laboratories ...
