Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the structure of pyruvate carboxylase when it is in solution (in the "natural" state). http://www.physorg.com/news168689251.html Biology Wed, 05 Aug 2009 11:08:01 EST news168689251 Different projects and research are under way to create standards indicating how good agricultural and livestock products taste. http://www.physorg.com/news168542502.html Chemistry Mon, 03 Aug 2009 22:10:01 EST news168542502 There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease. A new study, published in the August 11, 2009, issue of the Journal of the American College of Cardiology, extensively reviews data from a broad range of studies in tens of thousands of patients and sets forth suggested daily targets for omega-3 consumption. http://www.physorg.com/news168539596.html Medicine & Health Mon, 03 Aug 2009 20:50:01 EST news168539596 Scientists at Washington University School of Medicine in St. Louis have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes, hypertension or cardiovascular disease using treatments delivered in food rather than medication. http://www.physorg.com/news168179215.html Medicine & Health Thu, 30 Jul 2009 13:40:02 EST news168179215 Current research suggests that a diet high in omega-3 fatty acids may help prevent one of the leading causes of legal blindness among the elderly. The related report by Tuo et al, "A high omega-3 fatty acid diet reduces retinal lesions in a murine model of macular degeneration," appears in the August 2009 issue of the American Journal of Pathology. http://www.physorg.com/news167548837.html Medicine & Health Thu, 23 Jul 2009 06:21:43 EST news167548837 A team of researchers from the Yale University (United States) and a Spanish company have developed a system to detect the vapours emitted by human skin in real time. The scientists think that these substances, essentially made up of fatty acids, are what attract mosquitoes and enable dogs to identify their owners. http://www.physorg.com/news167480588.html Chemistry Wed, 22 Jul 2009 11:23:42 EST news167480588 Experts estimate that over 24 million people worldwide suffer from dementia, and many of these people live in low- and middle-income countries. Recently, there has been growing interest in whether dietary factors, particularly oily fish and meat, might influence the onset and/or severity of dementia. http://www.physorg.com/news167050084.html Medicine & Health Fri, 17 Jul 2009 11:48:33 EST news167050084 Consumers may be able to eat longer-lasting, potentially healthier fish fillets if research at Oregon State University makes its way to the supermarket. http://www.physorg.com/news166982443.html Chemistry Thu, 16 Jul 2009 17:01:18 EST news166982443 Results from two large studies using DHA, an omega 3 fatty acid, were reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna. http://www.physorg.com/news166596511.html Medicine & Health Sun, 12 Jul 2009 05:49:12 EST news166596511 A study comparing how two common dietary oil supplements affect body composition suggests that both oils, by themselves, can lower body fat in obese postmenopausal women with Type 2 diabetes. http://www.physorg.com/news166186990.html Medicine & Health Tue, 07 Jul 2009 12:03:31 EST news166186990 The Department of Energy's Joint Genome Institute (JGI) announced today that they will sequence the genomes of four species of labyrinthulomycetes. These little-known marine species were selected for sequencing as the result of a proposal submitted to the competitive JGI Community Sequencing Program by a team of microbiologists led by Dr. Jackie Collier, assistant professor at the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University. http://www.physorg.com/news165498490.html Biology Mon, 29 Jun 2009 12:48:47 EST news165498490 Pancreatitis is often a fatal condition, in which the pancreas digests itself and surrounding tissue. Scientists have previously found that alcohol can trigger the condition by combining with fatty acids in the pancreas, which leads to an excessive release of stored calcium ions. Once calcium ions enter cell fluid in the pancreas it activates digestive enzymes and damages the cells. http://www.physorg.com/news165489834.html Medicine & Health Mon, 29 Jun 2009 10:40:03 EST news165489834 Between the 1932 and 2008 Olympic Games, world record times of the men's 100m sprint improved by 0.6 seconds. Scientists at the Research Institute of Wildlife Ecology in Austria have shown that an equivalent improvement can be achieved in mice by feeding them a diet high in a certain type of polyunsaturated fatty acid. Dr. Christopher Turbill will present the research at the Society for Experimental Biology meeting on Monday, June 29. http://www.physorg.com/news165474068.html Biology Mon, 29 Jun 2009 06:01:59 EST news165474068 Research lead by Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, identifying an enzyme that makes neuroprotectin D1 which specifically and selectively protects retinal cells key for vision, will be published in the June 26, 2009 issue of the Journal of Biological Chemistry. http://www.physorg.com/news165236810.html Chemistry Fri, 26 Jun 2009 12:07:21 EST news165236810 (AP) -- Vermont dairy farmers Tim Maikshilo and Kristen Dellert, mindful of shrinking their carbon footprint, have changed their cows' diet to reduce the amount of gas the animals burp - dairy cows' contribution to global warming. http://www.physorg.com/news164810504.html Space & Earth Sun, 21 Jun 2009 13:42:30 EST news164810504 Researchers in Japan are reporting new evidence that the ordinary vinegar -- a staple in oil-and-vinegar salad dressings, pickles, and other foods -- may live up to its age-old reputation in folk medicine as a health promoter.
