Chronic Consumption of Farmed Salmon Containing Persistent Organic Pollutants Causes Insulin Resistance and Obesity in Mice
Ibrahim, Mohammad Madani; Fjære, Even; Lock, Erik-Jan; Naville, Danielle; Amlund, Heidi; Meugnier, Emmanuelle; Battistoni, Brigitte Le Magueresse; Frøyland, Livar; Madsen, Lise; Jessen, Niels; Lund, Sten; Vidal, Hubert; Ruzzin, Jérôme (Peer reviewed; Journal article, 2011-09-23)Background: Dietary interventions are critical in the prevention of metabolic diseases. Yet, the effects of fatty fish consumption on type 2 diabetes remain unclear. The aim of this study was to investigate whether a diet ... -
Dietary linoleic acid elevates the endocannabinoids 2-AG and anandamide and promotes weight gain in mice fed a low fat diet
Alvheim, Anita Røyneberg; Torstensen, Bente Elisabeth; Lin, Yu Hong; Lillefosse, Haldis Haukås; Lock, Erik-Jan; Madsen, Lise; Frøyland, Livar; Hibbeln, Joseph R.; Malde, Marian Kjellevold (Peer reviewed; Journal article, 2014-01)Dietary intake of linoleic acid (LNA, 18:2n-6) has increased dramatically during the 20th century and is associated with greater prevalence of obesity. The endocannabinoid system is involved in regulation of energy balance ... -
Effects of Frozen Storage on Phospholipid Content in Atlantic Cod Fillets and the Influence on Diet-Induced Obesity in Mice
Fauske, Kristin Røen; Bernhard, Annette; Fjære, Even; Myrmel, Lene Secher; Frøyland, Livar; Kristiansen, Karsten; Liaset, Bjørn; Madsen, Lise (Peer reviewed; Journal article, 2018-05-30)A large fraction of the n-3 polyunsaturated fatty acids (PUFAs) in cod fillet is present in the form of phospholipids (PLs). Freezing initiates hydrolysis of the PLs present in the fillet. Here, we compared the effects of ... -
Improved Quantification of Prostaglandins in Biological Samples by Optimizing Simultaneously the Relationship Eicosanoid/Internal-Standard and Using Liquid Chromatography Tandem Mass Spectrometry
Araujo, Pedro; Bjørkkjær, Tormod; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2007-07)Although a wide variety of articles on quantification of eicosanoids by using internal standards are published every year, little has been done on how much internal standard should be added. This article demonstrates that ... -
No Protection against DSS-induced Colitis by Short-term Pretreatment with Seal or Fish Oils in Rats
Arslan, Gülen; Erichsen, Kari; Milde, Anne Marita; Helgeland, Lars; Bjørkkjær, Tormod; Frøyland, Livar; Berstad, Arnold (Peer reviewed; Journal article, 2007-04-30)Background: Omega-3 (n-3) polyunsaturated fatty acids (PUFAs) have modulating effects in several chronic infl ammatory conditions. The aim of the present study was to test whether prior short-term dietary supplementation ... -
A randomized double blind comparison of short-term duodenally administrated whale and seal blubber oils in patients with inflammatory bowel disease and joint pain
Bjørkkjær, Tormod; Araujo, Pedro; Madland, Tor Magne; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2009)Compared with soy oil, 10 days treatment with seal oil (SO), 10 mL×3 daily, self-administrated through a nasoduodenal feeding tube, relieves joint pain in patients with inflammatory bowel disease (IBD). This randomized, ... -
Reduced Joint Pain after Short-term Duodenal Administration of Seal Oil in Patients with Inflammatory Bowel Disease: Comparison with Soy Oil
Bjørkkjær, Tormod; Brunborg, Linn Anne; Arslan, Gülen; Lind, Ragna Anne; Brun, Johan Gorgas; Valen, Merete; Klementsen, Beate; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2004)Background: Rheumatic joint pain is a common extraintestinal complication of inflammatory bowel disease (IBD). Because the high ratio of n-6 to n-3 fatty acids (FAs) of the Western diet might promote rheumatic disorders, ... -
Short-term duodenal seal oil administration normalised n-6 to n-3 fatty acid ratio in rectal mucosa and ameliorated bodily pain in patients with inflammatory bowel disease
Bjørkkjær, Tormod; Brun, Johan Gorgas; Valen, Merete; Arslan, Gülen; Lind, Ragna Anne; Brunborg, Linn Anne; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2006-03-20)Background: A high dietary intake of n-6 compared to n-3 fatty acids (FAs) may promote the production of pro-inflammatory eicosanoids and cytokines. In two recent studies, short-term (10- day) duodenal administration of ... -
