      Olsen, Thomas; Vinknes, Kathrine; Blomhoff, Rune; Lysne, Vegard; Midttun, Øivind; Dhar, Indu; Ueland, Per Magne; Svingen, Gard Frodahl Tveitevåg; Pedersen, Eva Ringdal; Drevon, Christian A; Refsum, Helga; Nygård, Ottar (Peer reviewed; Journal article, 2019-09-09)
      Purpose: We hypothesized that biomarkers and dietary factors related to cardiovascular disease risk were associated with serum retinol and evaluated these potential associations in patients with suspected coronary artery ...
    • Peroxisome Proliferator-Activated Receptor Activation is Associated with Altered Plasma One-Carbon Metabolites and B-Vitamin Status in Rats 

      Lysne, Vegard; Strand, Elin; Svingen, Gard Frodahl Tveitevåg; Bjørndal, Bodil; Pedersen, Eva Ringdal; Midttun, Øivind; Olsen, Thomas; Ueland, Per Magne; Berge, Rolf Kristian; Nygård, Ottar (Peer reviewed; Journal article, 2016-01-05)
      Plasma concentrations of metabolites along the choline oxidation pathway have been linked to increased risk of major lifestyle diseases, and peroxisome proliferator-activated receptors (PPARs) have been suggested to be ...
    • The risk association of plasma total homocysteine with acute myocardial infarction is modified by serum vitamin A 

      Olsen, Thomas; Vinknes, Kathrine; Svingen, Gard Frodahl Tveitevåg; Pedersen, Eva Ringdal; Dhar, Indu; Tell, Grethe S.; Blomhoff, Rune; Ueland, Per Magne; Midttun, Øivind; Refsum, Helga; Nygård, Ottar (Peer reviewed; Journal article, 2018)
      Background. Plasma total homocysteine (tHcy) has been implicated in the development of cardiovascular disease, but the mechanisms remain unclear. Vitamin A (Vit-A) is involved in homocysteine metabolism and we therefore ...
    • Serum Acylcarnitines and Risk of Cardiovascular Death and Acute Myocardial Infarction in Patients With Stable Angina Pectoris 

      Strand, Elin; Pedersen, Eva Ringdal; Svingen, Gard Frodahl Tveitevåg; Olsen, Thomas; Bjørndal, Bodil; Karlsson, Therese; Dierkes, Jutta; Njølstad, Pål Rasmus; Mellgren, Gunnar; Tell, Grethe S.; Berge, Rolf Kristian; Svardal, Asbjørn M.; Nygård, Ottar (Peer reviewed; Journal article, 2017-02)
      Background: Excess levels of serum acylcarnitines, which are intermediate products in metabolism, have been observed in metabolic diseases such as type 2 diabetes mellitus. However, it is not known whether acylcarnitines ...
