Compounds in cocoa may help decrease blood pressure

Compounds in cocoa may help to reduce blood pressure, according to a new systematic review in The Cochrane Library. The researchers reviewed evidence from short-term trials in which participants were given dark chocolate or cocoa powder daily and found that their blood pressure dropped slightly compared to a control group.

Ingredient for butter flavor in microwave popcorn is a respiratory hazard

The ingredient 2,3-pentanedione (PD), used to impart the flavor and aroma of butter in microwave popcorn, is a respiratory hazard that can also alter gene expression in the brain of rats. Manufacturers started using PD when another butter flavoring, diacetyl, was found to cause bronchiolitis obliterans, a life-threatening and nonreversible lung disease in workers who inhaled the substance.

Study finds evidence that smoking cessation is more difficult for women than men

A recent study challenged an enduring belief that women were less successful than men in quitting smoking. The study, published in the journal Tobacco Control, found convincing evidence that across all of the age groups, "there is relatively little difference in cessation between the sexes."

New melatonin analogues more efficient in inhibiting NOS activity in Parkinson's disease

University of Granada researchers have tested melatonin analogues in rats as it inhibits the enzyme nitric oxide synthase (NOS), which is involved in the development of conditions as inflammatory bowel disease, septic shock or rheumatoid arthritis, as well as in neurodegenerative conditions as Huntington's disease, Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis.

New photoactive compound eradicates 'Iraqibacter' from wounds and skin infections

Researchers at the University of California, Santa Cruz, have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder.

Study confirms that COX-2 inhibitors predispose people to cardiovascular disease

After nearly 13 years of study and intense debate, a pair of new papers from the Perelman School of Medicine, at the University of Pennsylvania have confirmed exactly how a once-popular class of anti-inflammatory drugs leads to cardiovascular risk for people taking it.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Helpful roles of rank, toxic substances

Usually, we think of mold, feces, nitric oxide, hydrogen sulfide and rat poison as rank, toxic or both. But scientists funded by the National Institutes of Health are learning more about the helpful roles these substances can play.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.
