Population biology changes in native dimorphic whitefish <i>Coregonus lavaretus</i> were studied over a decade in the subarctic Pasvik watercourse, where large biotric changes occurred due to an invasion by vendace <i> C. albula</i>. Although initially recorded in the upstream part of the watercourse, where it is now the dominant pelagic species, the vendace subsequently also colonised the downstream ...

Recently we reported on the development of a phospholipid vesicle-based barrier as a medium throughput method for screening of drug permeability. The aim of this present study is to characterize the barrier structure, including an estimation of the amount of phospholipid within it, its storage stability and its stability over various pH ranges found in different parts of the gastrointestinal tract. ...

Background: A previous study has shown that variations in threshold and intensity (lipid goal attainment) of statins for primary prevention contribute to regional differences in overall consumption of statins in Norway. Our objective was to explore how differences in prevalences of use, dosing characteristics, choice of statin and continuity of therapy in individual patients adds new information ...

Benthic marine invertebrates collected from sub-Arctic regions of northern Norway, were found to be a promising source of novel bioactive compounds against human and fish pathogenic bacteria and fungi. Lyophilized material from seven species of ascidians, six sponges and one soft alcyonid coral were extracted with 60% acidified acetonitrile (ACN). After separation into an ACN-rich phase (ACN extract) ...

<i>Hovedbudskap</i>: Mattilsynet og Direktoratet for naturforvalting (DN) ber Vitenskapskomiteen for mattrygghet om å vurdere den genmodifiserte bomullslinjen MON 15985 til import, prosessering, og til bruk i næringsmidler og fôrvarer. Søknaden gjelder ikke dyrking. Monsanto søkte opprinnelig om godkjenning av bomullslinjen i 2005, men søknaden ble trukket og erstattet av vedlagte søknad i 2008. I ...

Background: Poxvirus-vectored vaccines against infectious diseases and cancer are currently under development. We hypothesized that the extensive use of poxvirus-vectored vaccine in future might result in co-infection and recombination between the vaccine virus and naturally occurring poxviruses, resulting in hybrid viruses with unpredictable characteristics. Previously, we confirmed that ...

Background Polar bears (Ursus maritimus) are major predators in the Arctic marine ecosystem, feeding mainly on seals, and living closely associated with sea ice. Little is known of their gut microbial ecology and the main purpose of this study was to investigate the microbial diversity in faeces of polar bears in Svalbard, Norway (74-81 degrees N, 10-33 degrees E). In addition the level of blaTEM ...

Prostate cancer (PCa) patients receive androgen-deprivation therapy (ADT) to reduce tumor burden. However, complete eradication of PCa is unusual, and recurrent disease is evident within approximately 2 years in high-risk patients. Clinical evidence suggests that combining ADT with radiotherapy improves local control and disease-free survival in these patients compared with radiotherapy alone. ...
