Scientists in Texas are reporting development of a first-of-its-kind cloth that releases nitric oxide gas "” an advance toward making therapeutic socks for people with diabetes and a wrap to help preserve organs harvested for transplantation. The study is in ACS' Chemistry of Materials, a bi-weekly journal. Kenneth Balkus and Harvey Liu note in the new study that nitric oxide (NO) helps increase blood flow and regulates a range of other body functions. Scientists have tried for years to...

Researchers say having a glass or two of champagne a day is good for the heart and blood circulation, according to The Guardian Observer. According to University of Reading researchers, the fizz made with black grapes has the potential to reduce strokes and heart disease risk. Dr. Jeremy Spencer of University of Reading said, "We have found that a couple of glasses a day has a beneficial effect on the walls of blood vessels "“ which suggests champagne has the potential to reduce strokes...

Scientists have designed a synthetic protein that is both a structural model and a functional model of a native protein, nitric-oxide reductase. The designed protein "provides an excellent model system for studying nitric-oxide reductase, and for creating biocatalysts for biotechnological, environmental and pharmaceutical applications," said University of Illinois chemistry professor Yi Lu, who directed the work. "Through rational design, we can better understand native proteins, and maybe...

WINSTON-SALEM, N.C., Dec. 4 /PRNewswire-USNewswire/ -- A new, $2.8 million, four-year federal grant will support researchers at the University of Pittsburgh School of Medicine and their collaborators at Wake Forest University as they study why the quality of stored transfusion blood degrades over time and how to address the problem. This "storage lesion," as scientists call it, has been associated with increased risk for cardiovascular events and organ failure, particularly among...

U.S. scientists say they've demonstrated a new way of identifying nitric oxide gas using lasers and inexpensive, compact and highly sensitive sensors. Nitric oxide is a gas well known to scientists for its myriad functions, but which has proven challenging to measure accurately outside the laboratory. A team of researchers from Princeton and Rice Universities created the portable device that they say could be of great value to atmospheric science, pollution control, biology and medicine. The...

The National Oceanic and Atmospheric Administration says nitrous oxide has become Earth's largest ozone-depleting substance emitted through human activities. NOAA scientists said they have, for the first time, evaluated nitrous oxide emissions in terms of their potential impact on Earth's ozone layer. Not only did they find nitrous oxide to be the top ozone-depleting substance, but they said they expect it to remain so throughout the 21st century. The scientists said nitrous oxide -- also...

Ancient Chinese herbal formulas for heart disease may produce large amounts of artery-widening nitric oxide, U.S. researchers said. Researchers at The University of Texas Health Science Center at Houston said nitric oxide is crucial to the cardiovascular system because it signals the inner walls of blood vessels to relax -- facilitating the flow of blood through the heart and circulatory system. Senior author Nathan S. Bryan said the study reveals that ancient Chinese herbal formulas have...

New research at The University of Texas Health Science Center at Houston suggests that ancient Chinese herbal formulas used primarily for cardiovascular indications including heart disease may produce large amounts of artery-widening nitric oxide. Findings of the preclinical study by scientists in the university's Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases (IMM) appear in the Sept. 15 print issue of the journal Free Radical Biology &...

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...

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...
