Researchers at the Johns Hopkins School of Medicine have discovered how one antioxidant protein controls the activity of another protein, critical for the development of spinal cord neurons. The research, publishing this week in Cell, describes a never-before known mechanism of protein control.

A new study finds that many women with breast cancer take antioxidant supplements while undergoing cancer treatment, even though the consequences of doing so are unknown. Published in the July 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that additional research should be undertaken to determine the effects of antioxidant supplementation on the health and survival of breast cancer patients.

Researchers have widely believed that the organic compound, allicin – which gives garlic its aroma and flavour – acts as the world's most powerful antioxidant. But until now it hasn't been clear how allicin works, or how it stacks up compared to more common antioxidants such as Vitamin E and coenzyme Q10, which stop the damaging effects of radicals.

Antioxidant supplementation was found to be effective in relieving pain and reducing levels of oxidative stress in patients with chronic pancreatitis (CP), reports a new study in Gastroenterology.

Diets and beauty products which claim to have anti-oxidant properties are unlikely to prevent ageing, according to research funded by the Wellcome Trust. Researchers at the Institute of Healthy Ageing at UCL (University College London) say this is because a key fifty year old theory about the causes of ageing is wrong.

Over the past ten years, dark chocolate and cocoa have become recognized through numerous studies for flavanol antioxidant benefits. In a study published this month in the Journal of Agricultural and Food Chemistry, scientists from The Hershey Company and Brunswick Laboratories of Norton, MA report on the levels of antioxidants in selected cocoa powders and the effect of processing on the antioxidant levels.

A Brazilian palm berry sweeping the globe as a popular health food - though little research has been done on it – now may have its purported benefits better understood.

Plums: they're sweet, juicy, and packed with beneficial antioxidants and dietary fiber. Although there are many varieties available to consumers, there are two main types of the small, purple fruit: Japanese plums and European plums.

Cranberries are tart, tiny fruits packed with powerful antioxidants. The small, red berries offer a wide variety of health benefits.

A recent study shows that a loss of antioxidants in the endothelial cells that line blood vessels in the lungs contributes to the loss of vasodilator effects and, ultimately, to the development of pulmonary hypertension. The findings appear in Clinical and Translational Science.

Taurine is a potent antioxidant with hepatoprotective effects. Organelle based changes in hepatocytes after taurine treatment in experimental liver fibrosis were searched systematically and organelle injury scores decreased were found to decrease significantly. Moreover, ultrastructural and histopathological scores in both groups were in strong correlation.

Researchers from Monash University have designed a nano-sized "trojan horse" particle to ensure healing antioxidants can be better absorbed by the human body.
