Resveratrol is a botanical antioxidant with diverse biologic effects. In this paper we will review the unique antioxidant activity of resveratrol including its effects on mitochondrial function. The molecular signaling of resveratrol and cellular mechanisms that make this botanical active an important anti-aging ingredient for topical application will be discussed.

BACKGROUND Atherogenic effects of ELF-MF exposure have not been studied well so far. Therefore we have hypothesized that ELF-MF exposure might have atherogenic effect by impairing antioxidant function and increasing lipid peroxidation. This study was therefore undertaken to examine the effects of ELF-MF on paraoxonase (PON) activity, antioxidant capacity and lipid peroxidation metabolites. Effe...

Extensive research on the nutritional and medical application of selenium nanoparticles (SeNPs) was performed in past decades. Besides nutritional values, new characteristics such as antibacterial and anticancer properties depict a bright future for high Selenium (Se) consumption in the coming years. Se is essential for the proper functioning of most of the m...

In this paper it is studied the ways by which the radical cation chromophore of chlorpromazine, produced through a reaction between chlorpromazine maleate and potassium persulfate in hydrochloric acid medium, can be applied in realization an evaluation method of the antioxidant activity. The chlorpromazine radical cation is a radical with biological relevance, being involved in oxidative proces...

Chocolate is a product processed from cocoa rich in flavonoids, antioxidant compounds, and bioactive ingredients that have been associated with both its healthy and sensory properties. Chocolate production consists of a multistep process which, starting from cocoa beans, involves fermentation, drying, roasting, nib grinding and refining, conching, and tempering. During cocoa processing, the nat...

Relations between structure, antioxidant capacity and formal redox potentials (E°’) of six flavonoids dissolved in acetonitrile were studied by cyclic voltammetry and square wave voltammetry using a glassy carbon electrode. This work shows correlation between the electrochemical parameter E°’ and the number of hydroxyl groups present in the B ring of flavonoids. Besides, it has been observed th...

Bilirubin, an abundant pigment that causes jaundice, has long lacked any clear physiologic role. It arises from enzymatic reduction by biliverdin reductase of biliverdin, a product of heme oxygenase activity. Bilirubin is a potent antioxidant that we show can protect cells from a 10,000-fold excess of H2O2. We report that bilirubin is a major physiologic antioxidant cytoprotectant. Thus, cellul...
