Decontamination of persistent organic pollutants in fishmeal and fish oil. Process optimization and modeling
Oterhals, Åge (Doctoral thesis, 2011-10-07)Persistent organic pollutants (POPs) are fat soluble chemical substances that persist in the environment and bioaccumulate in the food chain. Through long-range environmental transportation by air, water and migratory ... -
A diet containing cod backbone proteins attenuated the development of mesangial sclerosis and tubular dysfunction in male obese BTBR ob/ob mice
O'Keeffe, Maria; Oterhals, Åge; Weishaupt, Hrafn; Leh, Sabine; Ulvik, Arve; Ueland, Per Magne; Halstensen, Alfred; Marti, Hans Peter; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2023)Purpose The obese black and tan, brachyuric (BTBR) ob/ob mouse spontaneously develops features comparable to human diabetic nephropathy. The primary aim of the present study was to investigate if a diet containing fish ... -
Dietary fish intake increased the concentration of soluble ACE2 in rats: can fish consumption reduce the risk of COVID-19 infection through interception of SARS-CoV-2 by soluble ACE2?
O'Keeffe, Maria; Oterhals, Åge; Vikøren, Linn Anja Slåke; Drotningsvik, Aslaug; Mellgren, Gunnar; Halstensen, Alfred; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2023)The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the cells after binding to the membrane-bound receptor angiotensin-converting enzyme 2 (ACE2), but this may be prevented through interception by soluble ... -
Effect of cod residual protein supplementation on markers of glucose regulation in lean adults: A randomized double-blind study
Vildmyren, Iselin; Halstensen, Alfred; McCann, Adrian; Midttun, Øivind; Ueland, Per Magne; Oterhals, Åge; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2020)Large quantities of protein-rich cod residuals, which are currently discarded, could be utilized for human consumption. Although fish fillet intake is related to beneficial health effects, little is known about the potential ... -
