Antioxidant activity applying an improved ABTS radical cation decolorization assay.
A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates,Expand
The Antioxidant Activity of Regularly Consumed Fruit and Vegetables Reflects their Phenolic and Vitamin C Composition
Fruit and vegetables rich in anthocyanins demonstrated the highest antioxidant activities, followed by those rich in flavanones and flavonols, while the hydroxycinnamate-rich fruit consistently elicited the lower antioxidant activities. Expand
Interaction between flavonoids and the blood–brain barrier: in vitro studies
It is demonstrated that flavonoids and some metabolites are able to traverse the blood–brain barrier (BBB) and that the potential for permeation is consistent with compound lipophilicity. Expand
A controlled investigation of the cause of chronic idiopathic axonal polyneuropathy.
A logistic regression analysis identified environmental toxin exposure and hypertriglyceridaemia, but not glucose intolerance or alcohol overuse as significant risk factors that deserve further investigation as possible causes of CIAP. Expand
Potential problems of ascorbate and iron supplementation: pro-oxidant effect in vivo?
No compelling evidence for a pro-oxidant effect of ascorbate supplementation, in the presence or absence of iron, on DNA base damage was observed and a significant decrease occurred in levels of 8-oxo-7,8-dihydroguanine by ascorBate supplementation and 5-hydroxymethyl uracil by both ascor Bate plus iron supplementation. Expand
Iron supplementation and oxidative damage to DNA in healthy individuals with high plasma ascorbate.
There were no detrimental effects, over the period under investigation, in terms of oxidative damage to DNA, and the effects of larger doses or of longer supplementation periods should also be investigated. Expand
The Compositional Characterisation and Antioxidant Activity of Fresh Juices from Sicilian Sweet Orange (Citrus sinensis L. Osbeck) Varieties
Orange juices, particularly those rich in anthocyanins, may represent a significant dietary source of flavonoids, and a comparison of the phenolic compositions, the ascorbic acid contents and the antioxidant activities of fresh Sicilian orange juices showed a good correlation with the determined antioxidant capacity. Expand
Gender Differences in Steady-state Levels of Oxidative Damage to DNA in Healthy Individuals
The role of gender in predisposition to oxidative damage to DNA needs to be addressed in future studies and the results are discussed in relation to the Vitamin C and iron status of the subjects and to the existing, yet limited, literature data. Expand
Hesperetin Glucuronide, a Photoprotective Agent Arising from Flavonoid Metabolism in Human Skin Fibroblasts¶
The results indicate that hesperetin glucuronides, but not he Speretin, protect against UV-A-induced necrotic cell death. Expand
Ferulic and caffeic acids as potential protective agents against photooxidative skin damage
The biological properties and, particularly, the antioxidant activity of plant hydroxycinnamic acids, such as caffeic and ferulic acids, are well recognised. This preliminary study was designed toExpand
