A Boston University School of Medicine study suggests short bursts of nitrites can be beneficial in protecting the heart from stress. The study, researchers said, demonstrated for the first time that short elevations in circulating levels of nitrites are sufficient to have a lasting impact on the heart by modulating its oxidation status and its protein machinery. Nitrite is an oxidation product of the short-lived cell signaling molecule nitric oxide and, until recently, was thought to be...

High nitrate levels in water from parts of the Seymour Aquifer in Texas may make it unfit for human consumption but just right for irrigation, researchers said. The high concentration of nitrates -- as high as 40 parts per million in some areas -- exceeds federal safe drinking water standards for use as a municipal water source but the water would benefit agricultural producers, Texas A&M University researchers said in a release. When you get more than 10 parts per million, it exceeds the...

Agriculture producers may find they don't have to bottle their water from the Seymour Aquifer in the Rolling Plains to make it more valuable, according to Texas AgriLife Research scientists.Drs. John Sij, Cristine Morgan and Paul DeLaune have studied nitrate levels in irrigation water from the Seymour Aquifer for the past three years, and have found nitrates can be as high as 40 parts per million. Though unacceptable for drinking, the water would benefit agricultural producers who use it for...

A recently completed 16-year U.S. ground water study shows statistically significant increases in concentrations of nitrates in seven of 24 well networks. Nitrate is the most common chemical contaminant in the world's ground water, scientists said. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency because of health concerns related to infant health and possible cancer risks. Results of the U.S. Geological Survey study were analyzed to...

NFU Cymru is calling for a common-sense approach to new rules on nitrates and set-aside land. The union has called on the Welsh Assembly Government to justify its plans to extend Nitrate Vulnerable Zones in Wales and to drop any plans for extra environmental rules for farms to compensate for dropping the set-aside system. The union says nitrate levels are actually falling in Wales and is questioning the science behind WAG proposals to increase the amount of land designated NVZs....

Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature. In the first phase of the study, which involved 31 aquatic scientists from across the United States, researchers added small amounts of an uncommon non-radioactive isotope of nitrogen to 72 streams across the U.S. and Puerto Rico. Using this tracer, the team's objective was to...

Researchers at Barts and The London School of Medicine have discovered that drinking just 500ml of beetroot juice a day can significantly reduce blood pressure. The study, published online today in the American Heart Association journal Hypertension, could have major implications for the treatment of cardiovascular disease. Lead by Professor Amrita Ahluwalia of the William Harvey Research Institute at Barts and The London School of Medicine, and Professor Ben Benjamin of Peninsula Medical...

By Lansdown, A B G Silver is a xenobiotic element with no recognized trace metal value in the human body. It is absorbed into the body through the lungs, gastrointestinal tract, mucus membranes of the urinogenital tract, and through the skin, mainly in the form of silver protein complexes. Although silver is metabolized throughout the soft tissues, available evidence from experimental animal studies and human clinical reports has failed to unequivocally establish that it enters tissues of...
