    • Isolation and Characterisation of Halogenated and Bioactive Compounds from Thalassospira sp. and Alteromonas sp. 

      Ali, Nadia Ghazi (Master thesis; Mastergradsoppgave, 2019-05-15)
      Bacterial natural products have contributed with a large part of the bioactive compounds that lead to drugs, and the biggest portion of the marketed antibiotics are bacterial products or their derivatives. Marine bacteria are not yet investigated to the same extend as their terrestrial counterparts. Therefore, they are considered a promising source for novel bioactive metabolites for drug development, ...

      Thanki, Meera Satish (Master thesis; Mastergradsoppgave, 2010-06-17)
      Marine bioprospecting is a promising field of research that has gained interest worldwide for the past few decades, and can be characterised as a systematic and purpose oriented search for bioactive compounds or genetic material from marine sources. Several compounds have been isolated and some have found their way into the commercial market. The main aim of this master thesis was to investigate the ...
    • Isolation and characterization of antiviral compounds from marine organisms 

      Ammari, Yashar (Master thesis; Mastergradsoppgave, 2010-06-16)
      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 ...
    • Isolation and characterization of bioactive compounds from the marine hydrozoans Halecium muricatum and Halecium beanii 

      Korsmo, Kim André (Master thesis; Mastergradsoppgave, 2012-05)
      In the marine environment there is a great potential for discovering new commercial drugs, and marine bioprospecting has previously led to the discovery of drugs available for clinical use, like Yondelis ® and cytosine arabinoside. In this work two hydroids were tested for anticancer and antibacterial activity. The organic extracts from the two hydroids, Halecium muricatum and Halecium beanii, ...
    • Isolation and Characterization of Secondary Metabolites from Arctic Marine Hydroids 

      Harvey, Therese (Master thesis; Mastergradsoppgave, 2018-05-15)
      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, ...
    • Isolation and characterization of secondary metabolites from Arctic, Marine Invertebrates 

      Nyborg, Amalie Rebekka (Mastergradsoppgave; Master thesis, 2022-05-11)
      The search for bioactive compounds, or genes in macro- and microorganisms from the sea, is termed marine bioprospecting. Marine bioprospecting aims to increase the utilization and value of marine biomasses and organisms with the purpose of developing commercial products. Because of the special condition of the sea, it is known that marine invertebrates have adapted chemical defense strategies to ...
    • Isolation and characterization of wax esters from Calanus finmarchicus 

      Andersen, Toril (Master thesis; Mastergradsoppgave, 2010-06-16)
      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 ...
    • Isolation, characterization and chondrogenic differentiation of adult stem cell-derived MUSE-cells 

      Johansen, Lars-Arne (Master thesis; Mastergradsoppgave, 2016-05-13)
      Articular cartilage is coating the layers of freely movable joints, enabling a smooth surface and acts resisting to forces. The tissue is aneural and avascular, and has a poor ability to selfrenew in cases of tissue damage. Therefore, cartilage lesions often lead to degenerative disorders such as osteoarthritis (OA). OA is considered the most common form of arthritis affecting people worldwide, ...
    • Isolation, structure elucidation and bioactivity profiling of lyso-ornithine lipids from the marine bacterium Lacinutrix sp. 

      Jawad, Jawad (Master thesis; Mastergradsoppgave, 2021-05-11)
      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 ...
    • Isolering av villøse cytotrofoblaster fra humane, friske og fullgåtte placenta 

      Heide, Gøril (Master thesis; Mastergradsoppgave, 2011-09-15)
      Det er et paradoks at fosteret, som representerer fremmed vev, ikke avstøtes av morens immunsystem ved implantasjon. Stedsspesifikk suppresjon av den maternelle immunresponsen er foreslått som forklaring, og flere mekanismer for dette er kjent. Føtal og neonatal trombocytopeni (NAIT) er et av tilfellene hvor maternell immunisering kan føre til ødeleggelse av fosterets celler, i dette tilfellet ...

Det kan defineres som en formålrettet og systematisk leting etter bestander, bioaktive forbindelser eller gener i marine organismer med sikte på utvikling av et produkt som er kommersielt eller samfunnsmessige viktige. Målet med denne oppgaven er å lete etter forbindelser med anticancereffekt i ekstrakter av tre ulike ...
    • Isolering og vurdering av invariable NKT-cellers dreperfunksjon 

      Simonsen, Karsten Holt (Master thesis; Mastergradsoppgave, 2012-06-01)
      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 ...
    • Isolerte hurtighetstester som indikator på sprintprestasjoner i offisielle kamper. En kvalitativ studie som omhandler sammenhengen mellom sprint i felttest og sprint i kamp 

      Ryslett, Stian (Master thesis; Mastergradsoppgave, 2019-05-15)
      Studiet baserer seg på data som er samlet inn fra spillere som spiller i nasjonal serie G16 (N=18, alder=15.83±0.5 år). Data ble samlet inn fra både felttester og obligatoriske kamper. Kampdata ble hentet fra nasjonale seriekamper(N=11). Data fra felttester ble hentet fra hurtighetstester på 10, 20, 30 og 40 meter som ble gjennomført av de samme spillerne som ble målt i kamp. Her ble tiden på de ...

    • ‘It feels like my metabolism has shut down’. Negotiating interactional roles and epistemic positions in a primary care consultation 

      Lian, Olaug S; Nettleton, Sarah; Grange, Huw R.; Dowrick, Christopher (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-16)
      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 ...
