(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-07)The evolving situation in Lebanon is characterized by multiple crises that affect education and can negatively affect a student’s school-functioning and mental health. The Ministry of Education and Higher Education decided in 2019 to further intensify and upscale implementation of school-based psychosocial support. This study is a contextualization and validation of the Student Learning in ... -
High-resolution visualization and assessment of basal and OXPHOS-induced mitophagy in H9c2 cardiomyoblasts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)Mitochondria are susceptible to damage resulting from their activity as energy providers. Damaged mitochondria can cause harm to the cell and thus mitochondria are subjected to elaborate quality-control mechanisms including elimination via lysosomal degradation in a process termed mitophagy. Basal mitophagy is a house-keeping mechanism fine-tuning the number of mitochondria according to the metabolic ... -
Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-03)Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key arctic fish, may be at risk for crude oil exposure during this potentially sensitive life stage. Additionally, this species experiences lower food availability during their spawning ... -

In this article, we will have an in-depth look at the award-winning SOLIS technique (scanned oblique light-sheet instant-volume sectioning), a new twist on multifocus fluorescence microscopy. Through ... -
Shallow-water hydrothermal venting linked to the Palaeocene–Eocene Thermal Maximum
(Journal article; Tidsskriftartikkel, 2023-08-03)The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input of carbon into the ocean and atmosphere. Hydrothermal venting of greenhouse gases produced in contact aureoles surrounding magmatic intrusions in the North Atlantic Igneous Province have been proposed to play a key role in the PETM carbon-cycle perturbation, but the precise ... -
Støres floke i nord
(Chronicle; Kronikk, 2023-05-21)Problemene i nord forteller oss mye om både Arbeiderpartiets problemer generelt og i Nord-Norge spesielt. Jonas Gahr Støre er sannsynligvis den norske statsministeren i moderne tid som har hatt sterkest engasjement for Nord-Norge. Likevel styrer han nå mot nok et historisk svakt valgresultat i landsdelen. Hans floker i nord forteller oss mye om både Arbeiderpartiets problemer generelt og i Nord-Norge ... -
Systemic immune profile in Prader-Willi syndrome: elevated matrix metalloproteinase and myeloperoxidase and reduced macrophage inhibitory factor
(Journal article; Tidsskriftartikkel, 2023-07-10)Background - Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental syndrome with highly increased risk of obesity and cardiovascular disease (CVD). Recent evidence suggests that inflammation is implicated in the pathogenesis. Here we investigated CVD related immune markers to shed light on pathogenetic mechanisms.<p> <p>Methods - We performed a cross-sectional study with 22 participants ... -
ATPase activity of DFCP1 controls selective autophagy
(Journal article; Tidsskriftartikkel, 2023-07-08)Cellular homeostasis is governed by removal of damaged organelles and protein aggregates by selective autophagy mediated by cargo adaptors such as p62/SQSTM1. Autophagosomes can assemble in specialized cup-shaped regions of the endoplasmic reticulum (ER) known as omegasomes, which are characterized by the presence of the ER protein DFCP1/ZFYVE1. The function of DFCP1 is unknown, as are the mechanisms ... -
Bridging Law Application to Fracture of Fiber Concrete Containing Oil Shale Ash
(Journal article; Tidsskriftartikkel, 2023-07-23)Concrete is a widely used material in various industries, including hazardous waste management. At the same time, its production creates a significant carbon footprint. Therefore, intensive research is being conducted to create more eco-friendly concrete, for example, partially replacing cement with by-products such as oil shale ash (OSA) or improving properties by adding dispersed fibers such as ... -
Goldilocks Dilemma: LPS Works Both as the Initial Target and a Barrier for the Antimicrobial Action of Cationic AMPs on E. coli
(Journal article; Tidsskriftartikkel, 2023-07-20)Antimicrobial peptides (AMPs) are generally membrane-active compounds that physically disrupt bacterial membranes. Despite extensive research, the precise mode of action of AMPs is still a topic of great debate. This work demonstrates that the initial interaction between the Gram-negative E. coli and AMPs is driven by lipopolysaccharides (LPS) that act as kinetic barriers for the binding of AMPs to ... -
What we do in the dark: Prevalence of omnivorous feeding activity in Arctic zooplankton during polar night
(Journal article; Tidsskriftartikkel, 2023-07-04)During the productive polar day, zooplankton and sea-ice amphipods fulfill a critical role in energy transfer from primary producers to higher trophic-level species in Arctic marine ecosystems. Recent polar night studies on zooplankton and sea-ice amphipods suggest higher levels of biological activity than previously assumed. However, it is unknown if these invertebrates maintain polar night activity ... -
Ontogenetic changes in the body structure of the Arctic fish Leptoclinus maculatus
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)Histological studies of the ontogenetic changes in Arctic marine fishes are often fragmented and incomplete. Here we present a comprehensive histological ontogenetic analysis of the daubed shanny (<i>Leptoclinus maculatus</i>) from the Arctic, characterizing its development as it undergoes a series of changes in the organ and tissue organization, especially during the postlarvae transition from the ... -
Apparent universality of 1/f spectra as an artifact of finite-size effects
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-29)Power spectral density scaling with frequency f as 1/ f <sup>β</sup> and β ≈ 1 is widely found in natural and socioeconomic systems. Consequently, it has been suggested that such self-similar spectra reflect the universal dynamics of complex phenomena. Here, we show that for a superposition of uncorrelated pulses with a power-law distribution of duration times the estimated scaling exponents β¯ ... -
Estimating the information content of genetic sequence data
(Journal article; Tidsskriftartikkel, 2023-07-25)A prominent problem in analysing genetic information has been a lack of mathematical frameworks for doing so. This article offers some new statistical methods to model and analyse information content in proteins, protein families, and their sequences. We discuss how to understand the qualitative aspects of genetic information, how to estimate the quantitative aspects of it, and implement a statistical ... -
Metasurface supporting quasi-BIC for optical trapping and Raman-spectroscopy of biological nanoparticles
(Journal article; Tidsskriftartikkel, 2023-02-09)Optical trapping combined with Raman spectroscopy have opened new possibilities for analyzing biological nanoparticles. Conventional optical tweezers have proven successful for trapping of a single or a few particles. However, the method is slow and cannot be used for the smallest particles. Thus, it is not adapted to analyze a large number of nanoparticles, which is necessary to get statistically ... -
Ettpartidominans i et flerpartisystem: Norske Samers Riksforbund i Sametinget
(Journal article; Tidsskriftartikkel, 2023-06-16)Norske Samers Riksforbund (NSR) har dominert Sametinget siden Sametinget ble etablert med et flerpartisystem i 1989. Ved hvert valg har NSR vunnet flest representanter, de har for det meste vært hovedaktøren i dannelsen av sametingsråd og de har formet den samepolitiske dagsordenen. Artikkelen analyserer ved hjelp av teoriretningen historisk institusjonalisme hvorfor NSR fikk sin dominerende posisjon ... -
Predator–prey interactions in the Arctic: DNA metabarcoding reveals that nestling diet of snow buntings reflects arthropod seasonality
(Journal article; Tidsskriftartikkel, 2023-07-06)Tundra arthropods are of considerable ecological importance as a seasonal food source for many arctic-breeding birds. Dietary composition and food preferences are rarely known, complicating assessments of ecological interactions in a changing environment. In our field study, we investigated the nestling diet of snow buntings (Plectrophenax nivalis (L., 1758)) breeding in Svalbard. We collected fecal ...
