Mitophagy, the clearance of surplus or damaged mitochondria or mitochondrial parts by autophagy, is important for maintenance of cellular homeostasis. Whereas knowledge on programmed and stress-induced mitophagy is increasing, much less is known about mechanisms of basal mitophagy. Recently, we identified SAMM50 (SAMM50 sorting and assembly machinery component) as a receptor for piecemeal degradation ...

Artikkelen er inspirert av Stein Rokkans «impossibility theorem», som sier at integreringsmekanismene i den enkelte nasjonalstat er så omfattende at betingelsene for en sterk felles europeisk identitet med et institusjonelt politisk tillitsfellesskap ikke er mulig. Artikkelen snur blikket fra forholdet mellom den enkelte nasjonalstat og et overnasjonalt EU til betingelsene for nasjonsbygging på et ...

When students drop out of high school, this is often negative for their development as well as for society, as those who drop out have an increased risk of unemployment, health problems, and social problems. The aim of the present study was to synthesize knowledge regarding processes related to school dropout in general and school re-enrollment in particular. We performed a narrative review of ...

Background: Alcohol consumption among older adults is on the rise, which may be an increasing public health concern. The proportion of older adults who drink above defined low-risk drinking limits, associated characteristics and the sex distribution of at-risk drinking vary across countries. The aims of this study were to (i) estimate the prevalence of at-risk drinking among older adults in Norway, ...

Oil production in Arctic ice-covered areas poses a risk for pollution of the ecosystem including that within the brine channel network of sea ice. Sea-ice autotrophs contribute substantially to Arctic primary production, but are inherently difficult to test for oil exposure responses in situ. This study had two objectives, first, we developed a suitable lab-based mesocosm system, second, we tested ...

Salmon farming has been a great success story in Norway over the last 50 years, but the industry is still much disputed. Right from the start, farmers were licensed, with a limit on total production. In addition, each site was regulated according to carrying capacity. Over the years, various management measures have been used to regulate both the total production and environmental conditions, before ...

Objectives - The main objective was to gain more knowledge on exposure to bioaerosols in the processing area on board fishing trawlers.<p> <p>Methods - Exposure sampling was carried out during the work shifts when processing fish in the processing area on board five deep-sea fishing trawlers (trawlers 1–5). Exposure samples were collected from 64 fishermen breathing zone and from stationary ...

The European Commission’s recently published ‘Farm to Fork’ strategy seeks to facilitate a transition towards a sustainable food system. The strategy moves from a linear understanding of the food system towards a more circular view of the system’s complex interdependencies. Despite these laudable intentions, it does not follow the guidance of the EU’s Group of Chief Scientific Advisors that the ...

The effects of harvest and fluctuating environment on inter-dependent predators and prey are complex and not well-known. We define a stochastic model where the predators and prey dynamically interact. The novelty of the model holds on the fact that predators and prey dynamics are simultaneously affected by correlated environmental noises. Interacting predators and prey are harvested using a proportional ...

The Arctic is a climate-sensitive area, responding rapidly to present changes, but for the past changes, the recordis still incomplete. Forinstance, theWeichselian glacial historyof the Svalbard–Barents Sea Ice Sheet (SBIS) haslargely been reconstructed based on studies of the fragmentary Spitsbergen terrestrial and shelf records. However, the sediments removed from the land and shelf areas during ...
