Friday 3 June 2016 Karin Larsson defended her PhD thesis at the Department of Biology and Biological Engineering – Food and Nutrition Science, Chalmers University of Technology. The title of her work was Oxidation of fish lipids during gastrointestinal in vitro digestion. Prof. Ingrid Undeland has been Karin’s superviser, and Prof. Marie Alminger secondary supervisor. Abstract of Karin’s thesis is available here.
Our goal in Nordic Lipidforum is to be relevant for our members. We want to promote applied research and technology, be a contact network, provide information about network playground for Nordic and international meetings, to inspire talented employees to increase their competence in lipid science and development, and much more. This is only possible with active members that share news and relevant activities. If you want to share something you believe is of importance, do not hasitate to contact secretary or members of the board.
The Nordic Lipidforum is now present at LinkedIn, so sign up the group today.
We are a small «lipid family» in the Nordic countries. Everyone knows everyone. Almost. The number of members in Nordic Lipidforum has been relatively stable for years, but with a slight decline. In time of globalisation, we are happy to see that our presence also is taken notice of outside the Nordic countries. We have now members from Peru as well!
If you know someone, either a colleague or two, a friend or professional contact, that might be interested in joining the Nordic Lipidforum, just ask them to sign up. You will find information about membership fee and an online application form here.
We hereby request all members to pass forward our website to people they believe might be interested in, and advantage of joining Nordic Lipidforum. Let us set a goal of 50 more members by the end of 2016!
On the January 29th an animal study from University of Gothenburg showing increased cancer growth in mice supplemented with Vitamin E and N-acetylcystein, was published in Science Translational Medicine1. The study shows that tumour progression is markedly increased and survival time decreased in mice which were given the antioxidants after initiation of tumour development. These results are in accordance with earlier human studies, showing that smokers taking -carotene supplements had higher lung cancer incidence than smokers not taking any supplementation2. Data from the recent study indicate that the anti-oxidants protects the cancer-cells from the normal, reactive-oxygen species based defence system, that are used by the body to kill cancer cells. It does however not say anything on whether anti-oxidant supplements can increase protection of cancer formation, only that already established cancer-cells have increased survival and drive increased tumour progression.

In a recently published study, Cansell and co-workers show very clearly that the presence of triglycerides in the blood affects dopamine-signalling from the brain. This is part of the so called “reward-system”, which is very important in controlling preferences for palatable food. In the study, they show that infusing small amounts of triglycerides in the brain, this reduced the preference for palatable (sweet and fat) food and reduced their feed-seeking behaviour. This is might be an important finding, since it indicates that the triglyceride-peaks in the blood occurring after a meal is important in regulating appetite and preferences for energy-dense foodstuffs, and that increased strive after sugar and fat might be due to dysfunctions in this system.
