The reaction causing bioactivation is not well understoodSo-called nitrovasodilators such as nitroglycerin have been used effectively in the treatment of angina pectoris in coronary heart disease for more than century. Within the human body, nitric oxide (NO) is released from the nitroglycerin and in turn stimulates an enzyme that dilates the arteries and thus improves blood circulation. In 1998, Robert F. Furchgott, Ferid Murad and Louis Ignarro were awarded the Nobel Prize for Medicine for...

Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy.Their work, published in the August issue of The American Journal of Pathology, is the first to make the connection between eye disease and arginase, an enzyme known to be a player in cardiovascular disease, according to researchers at MCG and Charlie...

British researchers found drinking beetroot juice made it possible to exercise up to 14 percent longer. Their study, published in the Journal of Applied Physiology, suggested the nitrate in the juice may turn into nitric oxide in the body and reduce the oxygen cost of exercise. Researchers at the University of Exeter and Peninsula Medical School in England gave eight men -- ages 19-38 -- about 16 ounces of organic beetroot juice for six consecutive days before they completed a series of...

Wake Forest University scientists have developed a new research tool in the pursuit of heart medications based on the compound nitroxyl by identifying unique chemical markers for its presence in biological systems.Nitroxyl, a cousin to the blood-vessel relaxing compound nitric oxide, has been shown in studies to strengthen canine heart beats, but research into its potential benefits for humans has been slowed by a lack of specific detection methods."I think this is a very powerful tool to...

Chemists at the University of California-Santa Cruz say they've developed novel compounds that show promise for photodynamic cancer therapy. The compounds, called dye-sensitized ruthenium nitrosyls, are absorbed by cancer cells and respond to specific wavelengths of light by releasing nitric oxide, which triggers the cancer cells' death, the researchers said. For cancer treatment, you want localized delivery of a very high concentration of nitric oxide, said Professor Pradip Mascharak. We've...

More and more, scientists are getting a better grip on the nitrogen cycle. They are learning about sources of nitrogen and how this element changes as it loops from the nonliving, such as the atmosphere, soil or water, to the living, whether plants or animals. Scientists have determined that humans are disrupting the nitrogen cycle by altering the amount of nitrogen that is stored in the biosphere.The chief culprit is fossil fuel combustion, which releases nitric oxides into the air that...
