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...

Scientists at VIB and Ghent University in Flanders, Belgium have found an unexpected ally for the treatment of septic shock, the major cause of death in intensive care units. By inducing the release of nitric oxide (NO) gas in mice with septic shock, researchers Anje Cauwels and Peter Brouckaert discovered that the animal's organs showed much less damage, while their chances of survival increased significantly. That's contrary to all expectations, since it is generally assumed that nitric...

As good as laparoscopy is in preventing some of the stresses of open surgery on the body, it does have drawbacks, including reduced blood flow and organ dysfunction. Laparoscopy is a type of surgery in the abdomen done through small incisions. By adding another gas to the carbon dioxide used to inflate the surgical area during laparoscopy, researchers at Duke University Medical Center have found they can preserve more normal blood flow during noninvasive surgery. The gas ethyl nitrite (ENO)...

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...

In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. Nitric oxide, a gas well known to scientists for its myriad functions, has proven challenging to measure accurately outside the laboratory. A team of Princeton and Rice University researchers has demonstrated a new method of identifying the gas using lasers and sensors that are inexpensive, compact and highly sensitive. Such a portable device, suitable for...

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 &...
