Arachidonic acid is an omega-6 fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain. It is the counterpart to the saturated arachidic acid found in peanut oil.
Two new studies by a University of Pittsburgh research team suggest that omega-3 fatty acids - substances that are found in high concentrations in fish oils and certain seeds and nuts - significantly inhibit the growth of liver cancer cells.
Previous studies have suggested that when it comes to using aspirin as a preventative for heart attacks, it is less effective in women than in men.
In what is believed to be the first direct comparison of blood cell testing in both sexes of 81 milligrams of acetyl salicylic acid a day, Hopkins researchers found aspirin therapy prevents the clumping together of these clot-forming cells, called platelets.
Omega-6 fatty acids--such as those found in corn oil--caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center.
Since smoking became popular in America in the 1930s, lung cancer rates have continued to climb. Today, it is still the leading cause of cancer-related deaths, with totals more than the other five leading cancers combined.
Scientists in Cambridge have discovered that a brain protein called syntaxin enables fatty molecules, used widely in health supplements, to work in the brain to make it function properly. Lead Scientist, Dr Bazbek Davletov and his colleague Dr Colin Rickman from the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK report their findings in the journal Chemistry and Biology.
A group of researchers from Israel has discovered that rats exhibiting the signs of depression have increased levels of the omega-6 fatty acid, arachidonic acid, in their brains. The details of their findings appear in the June issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal.
Anticoagulation therapies, or treatments that reduce the amount of clotting factors in the blood, are quite common and used for a variety of reasons.
Austrian researchers in a world first have successfully engineered an allergy vaccine using a genetically modified version of the birch pollen allergen.
Eating such fish is encouraged as part of a healthy diet as their oils are rich in very long chain polyunsaturated fatty acids (VLCPUFAs). However, views on the health-promoting nature of VLCPUFAs have to be balanced against the marine pollution that can cause fish, and the oils extracted from them, to be contaminated with heavy metals and dioxins, and the fact that fish stocks are in global decline.
