In the last decade, the investigation of marine natural products has resulted in a remarkable number of compounds with promising biological activities. Marine natural products have been shown to display antibacterial, antifungal, anticancer, antiviral, antiparasitic, anti-inflammatory activity and several other pharmacological activities of benefit to humankind. In this project, an investigation ...

Metridium senile, Halocynthia pyriformis and ParaParastichopus tremulus were subjected to organic and aqueous extraction. The aqueous extract was made with water, while the organic was made with dichloromethane and methanol in 1:1 ratio. The aqueous and organic extracts were fractionated on reversed-phase HPLC and tested for antiviral activity against Herpes simplex virus-1. All the three organisms ...

Marine bioprospecting is the systematic search for and discovery of products from Nature, with potential of being developed into commercially available pharmaceuticals. The ocean represents the largest habitat on Earth, and represent a great resource of organisms with unique biological and chemical diversity. The marine environment makes the living condition challenging. To survive these conditions, ...

Calanus finmarchicus is a vast resource that until recently have been exploited to a minimal degree only. In the last few years harvesting and processing methods have been developed. There is a large market and great interest in products derived from marine oils. Most of the products today are derived from organisms at a high trophic level, i.e. products derived from cod liver oil. One disadvantage ...

From previous work, it was identified two analytes of interest, produced by Lacinutrix sp. The two analytes are iso-branched lyso-ornithine lipids with only one CH2 group differing between the two compounds, in the hydrocarbon chain (lysoC15:0 and C16:0). The bacterium was isolated from the marine sponge Halicondria sp. that was collected beside Bjørnøya, on a research cruise in 2009. The analytes ...

Antibakteriell aktivitet mot Gram positive og Gram negative bakterier er påvist i ekstrakter av celler og plasma fra Solaster endeca, Crossaster papposus og Urasterias Linckii. Det har også blitt påvist antibakteriell aktivitet mot Gram negative bakterier i ekstrakter av hel kropp fra Solaster endeca og Croassaster papposus. Materialet ble grovekstrahert med 60 % Acetonitril, videre ble vannfase og ...

Invariable Natural Killer T (iNKT) celler er en undergruppe av T-lymfocytter som interagerer med det non-polymorfe CD1d-molekylet og aktiveres av glykosphingolipid-antigener (som αGalCer ). iNKT celler kan produsere rikelige mengder immunoregulerende cytokiner som påvirker nivået av aktivering til mange typer celler og kan også drepe andre celler. Målet for denne oppgaven var å undersøke om iNKT-celler ...

The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is a scientific organization that encourages sound clinical practice, teaching and research related to diagnostic imaging in women's healthcare. The ISUOG Clinical Standards Committee (CSC) has a remit to develop Practice Guidelines and Consensus Statements as educational recommendations that provide healthcare practitioners ...

Introduction: Our aim is to explore the ways in which a patient and a general practitioner (GP) negotiate knowledge-claims stemming from different epistemic domains while dealing with a mismatch between experiential and biomedical knowledge during a clinical consultation. We interpret their interaction in relation to the sociocultural context in which their negotiation is embedded, and identify ...

Background - In South-Eastern Norway, genetic testing for BRCA1 and BRCA2 is offered to breast cancer patients by their treating surgeon or oncologist. Genetic counselling from a geneticist or a genetic counsellor is offered only to those who test positive for a pathogenic variant or have a family history of cancer. This practice is termed “mainstreamed genetic testing”. The aim of this study was ...
