Bakgrunn: Aortastenose er en sykdom som har økt forekomst med økende alder, og alvorlig symptomgivende aortastenose har en dyster prognose. Uten behandling er median overlevelsestid 2 år dersom pasienten utvikler hjertesvikt. Tidligere ble denne pasientgruppen operert med åpen hjertekirurgi, men mange fikk ikke tilbud om behandling grunnet omfattende komorbiditet og høy-risiko. Dermed oppstod behovet ...

Zooplankton patchiness has been documented in many shelf areas and is of vital importance for understanding predator-prey relationships in pelagic marine systems. By combining hydrographic, acoustic and net data collected in spring 2017, we present a detailed understanding of the extent of this phenomenon in the Lofoten-Vesterålen region. Such patches are of potential interest not only for zooplankton ...

The present contribution conducts an intervention in the study and practice of digital and media literacy. After reviewing key tenets of recent debates, I advance a specific under- standing of the concept – critical digital literacy – that, as I argue, comprehensively addresses issues of knowledge, competencies, and skills in relation to digital technologies. In particular, I posit that critical ...

One of the most significant epidemiological tools for the perceived truth about contemporary Norwegian youth is in Ungdata, Youth Data. This is a continuous online-based survey grounded upon several and varying investigations of youth in Norwegian high schools, now extending to primary schools as well. The knowledge bases, epidemiological practices, technicalities, economic premises for the work and ...

A long-standing issue in Russian linguistics concerns the noun in paucal constructions like dva goroda ‘two cities’. Is goroda the genitive singular of gorod, a separate ‘numerative case form’, or a ‘paucal number’? Although stress has figured prominently in the debate, corpus data and informant data regarding stress have received little attention. Based on the accentuated part of the Russian National ...

We discuss the influence of charged dust on radar observations in the Earth ionosphere. This region in the upper Earth atmosphere can be described as a partially ionized, low‐temperature plasma. Plasma parameters vary by orders of magnitude spatially and in time. Dust particles influence the charge balance, in some cases dusty plasma condition is met. The polar mesospheric echoes are an example of ...

Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...

The gene encoding MG Orn has been identified from a metagenomic library created from the intertidal zone in Svalbard and encodes a protein of 184 amino acid residues. The <i>mg orn</i> gene has been cloned, recombinantly expressed in <i>Escherichia coli</i>, and purified to homogeneity. Biochemical characterization of the enzyme showed that it efficiently degrades short RNA oligonucleotide substrates ...

The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO₂ supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and not yet estimated for the Arctic Ocean. With the severe climatic changes in the Arctic Ocean, impacting sea ice and potentially the vertical carbon transport mechanisms, ...

<i>Background</i>: The developing fetus is particularly vulnerable to the effects of endocrine disrupting chemicals (EDCs). Molecular fingerprints of EDCs can be identified via microRNA (miRNA) expression profiles and may be etiologically implicated in the developmental origin of disease (DOHaD).<p> <p><i>Methods/design</i>: This pilot study includes pregnant women at high risk (smoking at ...
