Current research suggests that nitric oxide may play a role in the pathogenesis of neonatal meningitis. The related report by Mittal et al, "Inhibition of inducible nitric oxide controls pathogen load and brain damage by enhancing phagocytosis of Escherichia coli K1 in neonatal meningitis," appears in the March 2010 issue of The American Journal of Pathology. Bacterial meningitis, or inflammation of the membranes that cover the brain and spinal cord, is often fatal, even when treated with...

A new study, published Thursday in Analytical Chemistry, states that the eye make-up worn by Cleopatra and other ancient Egyptians apparently had a dual purpose, shielding the wearer from the "evil eye" and protecting them from eye disease. According to French scientists, some 4,000 years ago ancient Egyptians used the make-up - made from lead and lead salts - to darken the eyes. The mixture sometimes took up to a month to create, Philippe Walter told AFP. Walter co-headed the research team...

The interaction of enzymes "“ especially the tyrosine kinases called Src and inducible nitric oxide synthase "“ plays an important role in the growth of non-small cell lung cancers, the most common form of this deadly disease in the United States, said researchers from Baylor College of Medicine in a report in the Journal of Biological Chemistry. Such cancers require activation of the epidermal growth factor receptor, said Dr. Tony Eissa, professor of medicine "“ pulmonary,...

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...
