THE ANTIOXIDANT PROPERTIES OF ZINC AND METALLOTHIONEIN
Neurochemistry International, 1996Support for the hypothesis that metallothionein isoforms participate in intracellular defense against reactive oxygen and nitrogen species is derived from observations that substances causing oxidative stress, such as ethanol and iron, and agents involved in inflammatory processes, such as interleukin-1 and tumour necrosis factor alpha, induce the ...

Antioxidant and anticancer properties of berries
Critical Reviews in Food Science and Nutrition, 2017The enduring relationship between dietary patterns and human health has led us to investigate the bioactive components present in fruits and vegetables for a very long time. Berries, notably the popular ones such as strawberry, raspberry, blueberry, blackberry, and the Indian gooseberry, are among the best known dietary sources due to the presence of a

Antioxidative properties of black tea
Preventive Medicine, 2005Black tea, obtained by tea leaves fermentation, is an oxidized product and contains mainly multimeric polyphenols, whose biological activity is not well documented. This paper reviews the available literature on the effects of black tea on health with a focus on its antioxidative activity.A review of the different issues and studies relating to ...

Antioxidant properties of DI- and polyamines
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19931. One diamine, putrescine and two polyamines, spermidine and spermine (PAs) of different concentrations, were processed through antioxidant systems in order to study their antioxidant effects. The systems investigated were as follows. 2. "Oxidative stress" was induced in RBCs to investigate filtration parameters, the effect of reduced glutathione (GSH)

Antioxidants-Carcinogenic and Chemopreventive Properties
1989Synthetic and naturally occurring antioxidants have a wide variety of biological actions in rodents in addition to their primary antioxidant activity. Some of the included biological effects are of direct interest in relation to studies of carcinogenicity and/or modulation of carcinogenesis.

Direct Antioxidant Properties of Creatine
Biochemical and Biophysical Research Communications, 2002Creatine is the most popular supplement proposed to be an ergogenic aid. There is some evidence in the literature that creatine supplementation increases lean body mass, muscular strength, and sprint power. However, the efficacy of creatine has not been consistent, and the potential mechanisms are unresolved.

Antioxidant properties of acetaminophen and cardioprotection
Basic Research in Cardiology, 2001The acute administration of acetaminophen to isolated, perfused guinea pig hearts appears to have cardioprotective effects against the injury/mechanical dysfunction caused by global, low-flow, myocardial ischemia and reperfusion. In the current study we selected ischemia/reperfusion and administration of sodium pentobarbital as perturbations of the ...

Antioxidant properties of ganglioside micelles
Free Radical Research, 2007Antioxidant activity of gangliosides GM1 and GT1b in the Fenton type of reaction was investigated by EPR spectroscopy using DMPO as a spin trap. Hydroxyl radical spin adduct signal intensity was significantly reduced in the presence of gangliosides at their micellar concentrations.

Antioxidant and Chelating Properties of Flavonoids
1996Publisher Summary Flavonoids are a group of naturally occurring, low molecular weight polyphenols of plant origin, which formally should be considered as benzo-γ-pyrone derivatives. This chapter discusses several groups of flavonoids: flavones (I), flavonols (Ia), flavanones (ll), and flavanols (IIa).

Chemical and Antioxidant Properties of Betalains
Journal of Agricultural and Food Chemistry, 2017Betalains are vacuolar pigments composed of a nitrogenous core structure, betalamic acid. Betalamic acid condenses with imino compounds (cyclo-DOPA/its glucosyl derivates) or amino acids/derivates to form violet betacyanins and yellow betaxanthins. These pigments have gained the curiosity of scientific researchers in recent decades.
