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.
According to new research from the U.S. controlling the level of a fatty acid in the brain could help treat Alzheimer's disease (AD).
A comprehensive review of current scientific literature, published in the peer-reviewed journal ecancer, has suggested that antidepressants can help the human body fight cancer by boosting its own immune response, amongst other mechanisms.
Dr. Marcus Conrad of the Institute of Clinical Molecular Biology and Tumor Genetics at the Helmholtz Zentrum Munchen has decrypted the molecular mechanism through which the death of cells is caused by oxidative stress.
"Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty acids, according to new research from Wake Forest University School of Medicine.
The known association between breast feeding and slightly higher IQ in children has been shown to relate to a particular gene in the babies, according to a report this week in the Proceedings of the National Academy of Sciences.
Omega-3 polyunsaturated fatty acids protect against the development and progression of retinopathy, a deterioration of the retina, in mice.
Martek Biosciences has announced that the European Patent Office (EPO) has granted another patent to Martek for ARA (arachidonic acid) oil made from Martek's microbial source for use in infant formula.
The reason behind why patients who are on aspirin still have heart attacks is an important topic in cardiovascular disease.
UCLA researchers found that altering the fatty acid ratio found in the typical Western diet to include more omega-3 fatty acids and decrease the amount of omega-6 fatty acids may reduce prostate cancer tumor growth rates and PSA levels.
Osteoarthritis, which usually develops between the ages of 40 and 50, is more prevalent in women. It is thought that sex hormones may play a role in developing the disease, since they can be involved in inflammation of the tissues affected by it.
COX enzymes - well-known for their contrasting role in cardiovascular biology - interact physically to form a previously unrecognized biochemical partnership and function in the development of blood vessels in a mouse model.
Arthritis and erectile dysfunction (ED) affect men more as they age.
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.
