Caffeic acid inhibits colitis in a mouse model -- is a drug-metabolizing gene crucial?
Researchers at Iowa State University have found that increased expression of a form of cytochrome P-450 is a key marker of inhibition of colitis in mice by caffeic acid, an anti-inflammatory antioxidant compound widely distributed in foods. The results, which appear in the June 2009 issue of Experimental Biology and Medicine, implicate CYP4B1, a form of cytochrome P450 previously found to be associated with resolution of allergic inflammation in another model.

Origins of sulfur in rocks tells early oxygen story
Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere. Now a team of geochemists can show an alternative origin for this isotopic composition that may point to an early, oxygen-rich atmosphere. (2009-04-16)

A hot solution to bean sprout safety
Bacterial infection of mung bean seeds can cause outbreaks of food poisoning when the sprouts are eaten.

Study: Fluid buildup in lungs is part of the damage done by the flu
In a fight against respiratory infections, the body typically produces a little fluid to help the lungs generate a productive cough. But new research suggests that the influenza virus can tip the balance toward too much fluid in the lungs, interfering with the supply of oxygen to the rest of the body. An immune response ultimately is needed to eliminate the virus, but this research suggests that it's not the presence of the virus alone that does all the harm to a sick person (2009-02-10)

U of Minnesota research finds most road salt is making it into the state's lakes and rivers
Research at the University of Minnesota has revealed that road salt used throughout the winter is making the state's lakes and rivers saltier, which could affect aquatic life and drinking water. The research indicates that better training of snow plow drivers and more judicious use of road salt could help lessen the impact and save the state money. (2009-02-10)

Hope for preventative treatment for cystic fibrosis lung disease
Heidelberg researchers have succeeded in preventing cystic fibrosis lung disease in an animal model by spraying amiloride into the lungs of young mice. This is the first therapy to successfully attack the root cause of the widespread hereditary disease in a living organism. When mice are given inhalation treatment with the drug in the first days of life, no thick mucus forms in the lungs and airway inflammation and chronic lung damage can be prevented. (2009-02-05)

Discovery of ionic elemental crystal against chemical intuition

Cutting salt isn't the only way to reduce blood pressure
Most people know that too much sodium from foods can increase blood pressure. A new study suggests that people trying to lower their blood pressure should also boost their intake of potassium, which has the opposite effect to sodium. Researchers found that the ratio of sodium-to-potassium in subjects' urine was a much stronger predictor of cardiovascular disease than sodium or potassium alone. (2009-01-26)

Low potassium linked to high blood pressure
As a risk factor for high blood pressure, low levels of potassium in the diet may be as important as high levels of sodium -- especially among African-Americans, according to research being presented at the American Society of Nephrology's 41st Annual Meeting and Scientific Exposition in Philadelphia, Pa. (2008-11-08)

Inland ants often prefer salt over sugar, implying salt may be a limitation on their activity
Mammals are limited by the availability of salt, and now researchers have shown that ants are too. In experiments in North, Central and South American, researchers from the universities of California, Oklahoma and Arkansas have shown that plant-eating and omnivorous ants living more than 60 miles inland are more interested in salt than sugar, with the preference greater the farther they live from the coast. Carnivorous ants show no such preference. (2008-10-27)
