Pine bark extract boosts nitric oxide production

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.

Worm study sheds light on how the human body ages

Microscopic worms used for scientific research are living longer despite cellular defects, a discovery that is shedding light on how the human body ages and how doctors could one day limit or reverse genetic mutations that cause inherited diseases, according to a new University of Colorado at Boulder study.

Ostructive sleep apnea and continuous positive airway pressure

Researchers in Brazil have found that treating patients who suffer from obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) dramatically reduces early indications of atherosclerosis in just months, linking OSA directly to the hardening or narrowing of the arteries.

Past clinical trials of vitamin E fatally flawed

Generations of studies on vitamin E may be largely meaningless, scientists say, because new research has demonstrated that the levels of this micronutrient necessary to reduce oxidative stress are far higher than those that have been commonly used in clinical trials.

Proteins Nox1 and Nox2 play important role in amyotrophic lateral sclerosis

University of Iowa researchers investigating the basic biology of cell signaling have made a discovery that may have therapeutic implications for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.

Link between nicotine and atherosclerosis

It's well known that smoking cigarettes increases risk for a host of serious health problems from cancer to heart disease. Now a new study from Weill Cornell Medical College in New York City looks at how they do their dirty work by contributing to atherosclerosis, or hardening of the arteries. The evidence points to nicotine, the addictive chemical in cigarettes.

Smoking and Alzheimer's disease

People who smoke are more likely to develop Alzheimer's disease or dementia than nonsmokers or those who smoked in the past, according to a study published in the September 4, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.
