Scientists study fish oil diet in bid to cut heart attack risks


Researchers at the University of Edinburgh will examine the way a fish-rich diet helps maintain a low risk of heart attack amongst Eskimos, in the first study of its kind to be carried out in the city. Investigators hope that the results would help to guide the development of future heart treatments.

Researcher Dr Jehangir Din explained: "We know that fish oils benefit the heart, but we don’t know how exactly how this process works. We intend to look at the action of both fish oil supplements and increased fish in the diet on the way the blood vessels of the body function. Heart attacks are caused by clots blocking inflamed arteries, so we will look at the effects of fish oils on inflammation and clot breakdown."

The study, which is already underway, will draw in men to help them study the effects of fish oils on the body’s blood vessels. The researchers are appealing for 20 healthy men aged 25-40 who smoke at least ten cigarettes a day and 30 life-long non-smokers aged 40-75 to join the study, which is based at the Royal Infirmary of Edinburgh. The study is due to end in the summer of 2005.

Dr Din said: "We need smokers for this study because we know smoking can impair blood vessel function and increase inflammation, and we are interested to learn if fish oil supplementation can counteract these effects."

Those interested in volunteering for the study should contact Dr Din on 44-131-242-1850 or email him at Travel and other expenses will be paid.

The study is funded by the British Heart Foundation. Iain Lowis, Director of the British Heart Foundation in Scotland, said: "There is consistent research evidence that supports the benefits of eating oily fish and its protection against cardiovascular disease. We welcome this further study at the University of Edinburgh, which has the potential to improve the future treatment of heart patients."

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
