Antioxidant capacity as influenced by total phenolic and anthocyanin content, maturity, and variety of Vaccinium species
Different cultivars of four Vaccinium species [Vaccinium corymbosum L (Highbush), Vaccinium ashei Reade (Rabbiteye), Vaccinium angustifolium (Lowbush), and Vaccinium myrtillus L (Bilberry)] were
Antioxidant and prooxidant behavior of flavonoids: structure-activity relationships.
The antioxidant and prooxidant behavior of flavonoids and the related activity-structure relationships were investigated in this study using the oxygen radical absorbance capacity assay. Three
Antioxidant Capacity of Tea and Common Vegetables
Previously, some fruits were shown to contain high antioxidant activities. In this paper, we report the antioxidant activities of 22 common vegetables, one green tea, and one black tea measured using
Transition Metals, Ferritin, Glutathione, and Ascorbic Acid in Parkinsonian Brains
Reduced glutathione and the shift of the iron (II)/iron (III) ratio in favor of iron ( III) suggest that these changes might contribute to pathophysiological processes underlying PD.
Increased iron (III) and total iron content in post mortem substantia nigra of parkinsonian brain
The changes in total iron, iron (III) and the iron (II)/iron ( III) ratio in the parkinsonian substantia nigra are likely to be involved in the pathophysiology and treatment of this disorder.
Reduced and oxidized glutathione in the substantia nigra of patients with Parkinson's disease
The finding that oxidized glutathione is not decreased in Parkinson's disease suggests that the decrease in reduced glutathion is not exclusively the consequence of neuronal loss in the substantia nigra but may indicate a state of oxidative stress.
Selective Increase of Iron in Substantia Nigra Zona Compacta of Parkinsonian Brains
Abstract: Histochemical and biochemical determinations of total iron, iron (II), and iron (III) contents in brain regions from Parkinson's and Alzheimer's diseases have demonstrated a selective
High-Performance Liquid Chromatography Coupled with Coulometric Array Detection of Electroactive Components in Fruits and Vegetables: Relationship to Oxygen Radical Absorbance Capacity
An HPLC procedure utilizing reversed-phase chromatography coupled with a coulometric array detection system was developed for the characterization of overall antioxidant status in fruits and
Reduced Brain Antioxidant Capacity in Rat Models of Betacytotoxic-Induced Experimental Sporadic Alzheimer’s Disease and Diabetes Mellitus
In the diabetic rats these abnormalities were not associated with the development of peripheral diabetic neuropathy (PDN) and were not prevented by the intracerebroventricularly (icv) pretreatment of glucose transport inhibitor 5–thio-d-glucose (TG) in the STZ-icv treated rats, suggesting different mechanism of STZ -induced central effects from those at the periphery.
Antioxidant capacity in postmortem brain tissues of Parkinson's and Alzheimer's diseases.
The results showed that in the SN of parkinsonian's brain the balance between production of free radicals and the neutralization by a complex antioxidant system is disturbed.
