The antioxidant and/or prooxidant ability of extracts obtained from wine waste were analyzed using in vitro and in vivo assays. Cyclic voltammetry was used as the in vitro assay to determine the antioxidant and/or prooxidant properties and, the in vivo effect on mycelial growth of the fungus Botrytis cinerea was evaluated. In addition, the prooxidant activity was evaluated by intracellular oxid...
The free fatty acids (FFA) effect on the oxidative stability of marine lipids was studied by fluorescence assessment. Under different reaction conditions including time, temperature, FFA content and types (different chain length and unsaturation degree), FFA were made to interact in model systems with a commercial marine oil (cod liver oil) and two different fish (hake and pout) white muscles. ...
objectives: we have investigated the effect of a saffron supplement, given at a dose of 100 mg/kg, on prooxidant-antioxidant balance (pab) in individuals with metabolic syndrome. materials and methods: a randomized, placebo-controlled trial design was used in 75 subjects with metabolic syndrome who were randomly allocated to one of two study groups: (1) the case group received 100mg/kg saffron ...
Hepatitis C virus (HCV) and HCV core protein are hypothesized to induce hepatic oxidative stress and exacerbate injury caused by other toxins such as ethanol that induce the cytochrome P450 enzyme, CYP2E1. In the current study, the effects of HCV core protein [sequence genotype 1b, (nt 342-915)] on parameters indicative of oxidative stress were evaluated in HepG2 cells stably over expressing CY...
Oxidative stress is an important aspect of toxicology and therefore of considerable interest. It can be traced back to 1954 when Gerschman et al. propounded the free radical theory which for the first time implicated partially reduced forms of oxygen in its toxic mechanism [1]. This was followed by Harman in 1956 proposing the concept of free radicals playing a role in the ageing process [2]. T...
Grapes are rich in polyphenolic compounds, which known for their beneficial effects on human health. Grape stems byproducts of the winemaking procedure. They exert antioxidant effects; however, they can also become pollutants when discarded without control into environment due to high organic content. The main aim present study was examine potential prooxidant/anticancer grape stem extracts, pr...
