Spared performance but increased uncertainty in schizophrenia: Evidence from a probabilistic decision-making task
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021)Aberrant attribution of salience to in fact little informative events might explain the emergence of positive symptoms in schizophrenia and has been linked to belief uncertainty. Uncertainty is thought to be encoded by neuromodulators, including norepinephrine. However, norepinephrinergic encoding of uncertainty, measured as task-related pupil dilation, has rarely been explored in schizophrenia. ... -
Fatty acid profile of cooked leg meat and raw hepatopancreas of red king crab (Paralithodes camtschaticus) during three-month live holding without feeding at 5 and 10 °C
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-06)The red king crab (RKC, Paralithodes camtschaticus) is a highly-valued decapod species. Typically, RKCs undergo a period of live holding (LH), often without feeding, in onshore facilities, allowing for flexible management before export to destination markets. This study aimed to (i) gain information on the fatty acid (FA) profile of the cooked leg meat and raw hepatopancreas obtained from RKC harvested ... -
Effects of a wave power park with no-take zone on decapod abundance and size
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-11)Past studies have revealed higher levels of biodiversity, total abundance, and size of individuals around offshore installations of renewable energy. This study investigated the effects of Lysekil wave power park (area 0.5 km2) on the abundance and carapace size of decapods at the Swedish west coast.

Issues of under-representation in quantitative DNA metabarcoding weaken the inference about diet of the tundra vole Microtus oeconomus
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)During the last decade, methods based on high-throughput sequencing such as DNA metabarcoding have opened up for a range of new questions in animal dietary studies. One of the major advantages of dietary metabarcoding resides in the potential to infer a quantitative relationship between sequence read proportions and biomass of ingested food. However, this relationship’s robustness is highly dependent ... -
Probability distributions for wind speed volatility characteristics: A case study of Northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11)The Norwegian Arctic is rich in wind resources. The development of wind power in this region can boost green energy and also promote local economies. In wind power engineering, it is a tremendous advantage to base projects on a sound understanding of the intrinsic properties of wind resources in an area. Wind speed volatility, a phenomenon that strongly affects wind power generation, has not received ... -
Single-shot fringe pattern phase retrieval using improved period-guided bidimensional empirical mode decomposition and Hilbert transform

Between-study differences in grip strength: a comparison of Norwegian and Russian adults aged 40-69 years
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-03)Background - Identifying individuals with low grip strength is an initial step in many operational definitions of sarcopenia. As evidence indicates that contemporaneous Russian populations may have lower mean levels of grip strength than other populations in northern Europe, we aimed to: compare grip strength in Russian and Norwegian populations by age and sex; investigate whether height, body mass ... -
Samfunnsoppdrag under press Erfaringer og vurderinger i norske bibliotek under Covid-19
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-15)Siden mars 2020 har Covid-19-pandemien rammet det norske samfunnet på ulike måter. Foruten de helsemessige ringvirkningene, har privat og offentlig sektor vært nødt til å tilpasse seg den pågående krisen. De første inngripende smitteverntiltakene i Norge ble innført 12. mars. Sentrale myndigheter ga beskjed om at skoler og barnehager skulle stenge –sammen med blant annet kultur-og ... -

The wHole Story About Fenestrations in LSEC
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-13)The porosity of liver sinusoidal endothelial cells (LSEC) ensures bidirectional passive transport of lipoproteins, drugs and solutes between the liver capillaries and the liver parenchyma. This porosity is realized via fenestrations – transcellular pores with diameters in the range of 50–300 nm – typically grouped together in sieve plates. Aging and several liver disorders severely reduce LSEC ... -

Dysregulated non-coding telomerase RNA component and associated exonuclease XRN1 in leucocytes from women developing preeclampsia-possible link to enhanced senescence
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-05)Senescence in placenta/fetal membranes is a normal phenomenon linked to term parturition. However, excessive senescence which may be induced by telomere attrition, has been associated with preeclampsia (PE). We hypothesized that the telomerase complex in peripheral blood mononuclear cells (PBMC) and circulating telomere associated senescence markers would be dysregulated in women with PE. We measured ... -
Cutoff criteria for the placebo response: a cluster and machine learning analysis of placebo analgesia.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)Computations of placebo effects are essential in randomized controlled trials (RCTs) for separating the specific effects of treatments from unspecific effects associated with the therapeutic intervention. Thus, the identification of placebo responders is important for testing the efficacy of treatments and drugs. The present study uses data from an experimental study on placebo analgesia to suggest ...
