Nitric oxide has emerged as an important signaling molecule in plants - as in mammals including people. In studies of a tropical medicinal herb as a model plant, researchers have found that nitric oxide targets a number of proteins and enzymes in plants.

Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature.

A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are constructed.

Nitric oxide (NO) is a gas released by cells in the lungs. When a person with allergies and/or asthma experiences an inflamed airway, the inflammatory cells release more NO and the NO levels increase.

A study to be published in the October edition of Hypertension Research reveals Pycnogenol, (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, helps individuals by enhancing healthy nitric oxide (NO) production which leads to an increase in blood flow and oxygen supply to muscles.

Administering inhaled nitric oxide (NO) during surgery helps protect liver transplant patients from organ failure, according to a new study from researchers at the University of Alabama at Birmingham (UAB).

Nitric oxide (NO) acts as a biological mediator throughout the body; for example, if the pressure in a blood vessel increases, the cells that line the blood vessel produce NO, which causes the surrounding smooth muscle cells to relax so that the blood vessels dilate and the pressure in the vessel drops.

A new report from a team of researchers at the University of Washington, Seattle, and the University of Alabama at Birmingham indicates that one of the main complications of liver transplantation can be treated very simply by allowing the transplant recipients to inhale nitric oxide (NO) during the operation in which they received their new liver.

A nationwide study led by researchers at UCSF provides evidence that inhaled nitric oxide is safe and effective for the prevention of the most common type of long-term lung disease of very premature infants.

Use of nitric oxide in patients with acute lung injury does not improve survival and may cause harm, warn researchers in a study published on bmj.com today.
