    • Direct and indirect risk associated with the use of dietary supplements among persons with dementia in a Norwegian memory clinic 

      Risvoll, Hilde; Giverhaug, Trude; Halvorsen, Kjell H.; Waaseth, Marit; Musial, Frauke (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-12)
      Background: The use of dietary supplements (DS) is common among persons with dementia. Direct risks associated with DS use include adverse events and DS-drug interactions. A direct risk is a risk caused by the treatment itself. Indirect risks are related to the treatment setting, such as the conditions of use, and not to the treatment itself. Because dementia symptoms may reduce a person’s ability ...

    • Hormone therapy use, sex hormone concentrations and gene expression : The Norwegian Women and Cancer study (NOWAC) 

      Waaseth, Marit (Doctoral thesis; Doktorgradsavhandling, 2010-08-27)
      I følge salgsstatistikken økte forbruket av hormontilskudd kraftig i Norge på 1990-tallet, men avtok fra 2002. Både hormontilskudd og kroppens egenproduserte kjønnshormoner er relatert til kreft hos kvinner, bl.a. brystkreft. Kreft karakteriseres ved ukontrollert celledeling som utvikles gradvis gjennom endringer i genmaterialet. Teknologisk utvikling gjør det mulig å utforske sammenhenger mellom ...

      Olsen, Karina Standahl; Fenton, Christopher Graham; Frøyland, Livar; Waaseth, Marit; Paulssen, Ruth H; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      High blood concentrations of n-6 fatty acids (FAs) relative to n-3 FAs may lead to a “physiological switch” towards permanent low-grade inflammation, potentially influencing the onset of cardiovascular and inflammatory diseases, as well as cancer. To explore the potential effects of FA ratios prior to disease onset, we measured blood gene expression profiles and plasma FA ratios (linoleic ...
