This study aimed to investigate the effects of vitamin and antioxidant supplements in the prevention of bladder cancer using a meta-analysis of randomized controlled trials (RCTs). Fourteen RCTs were included in the final analysis. In a fixed-effect meta-analysis, vitamin and antioxidant supplements showed no preventive effect for bladder cancer (relative risk [RR] = 1.04; 95% confidence interv...

Potentilla species have been used in traditional medicine in the treatment of different ailment, disease or malady. Potentilla reptans (P. reptans) has been scarcely studied. The aim of this study was to test antioxidant and anti-inflammatory activity of P. reptans aerial part and rhizome. DPPH assay was used to measure antioxidant activity of aqueous plant extracts. Anti-inflammatory effect wa...

the genus phoenix is one of the most widely cultivated groups of palms around the world. the aim of this study was to determine the antioxidant activity and total phenolic compounds of 14 different varieties of date palm (phoenix dactylifera l., arecaceae) seed extracts with 5 solvents [water, methanol, methanol (50%), dmso, and water: methanol: acetone: formic acid (20:40:40:0.1)]. ferric redu...

The notion that dietary antioxidants can help fight cancer is popular. However, the mechanism(s) behind the effect of antioxidants in cancer is still unclear. Previous studies indicate that supplements can influence gene expression; however, all of these studies were focused on the coding/exonic gene expression. Studies are now emerging to highlight critical functional roles for RNAs expressed ...

The effects of cultural system and essential oil treatment on antioxidant capacities in raspberries were evaluated. Raspberries were hand-harvested from organic and conventional farms in Maryland, USA, and were treated with essential oil including carvacrol, anethole, cinnamic acid, perillaldehyde, cinnamaldehyde, and linalool. Results from this study showed that raspberries grown from organic ...

Aim of the study: To evaluate the antioxidant property of Smilax zeylanica L. using CCl4 hepatotoxicity in rats. Materials and methods: Hepatotoxicity was induced in Wistar albino rats by administration of CCl4 (0.5ml/kg/day p.o. for 7days). Methanol extract of S. zeylanica roots and rhizomes (SZRM) was administered to the experimental animals at doses 200,400 and 600 mg/kg/day, p.o. for 7 days...

This study was undergone to evaluate the in-vivo anti-hyperglycemic and antioxidant potential of ethanolic extract of leaves of Tecomella undulata Seem. on streptozotocin-nicotinamide induced type 2 diabetic rats. Type 2 diabetes was induced by single intraperitoneal injection (i.p.) of 60 mg/kg streptozotocin, 15 minutes after the i.p administration of 110 mg/kg body weight of nicotinamide. Th...

This paper reports the protective effect of the phenolic fraction extracted from extra virgin olive oils (OOPEs) against the cytotoxic effects of reactive oxygen species in human erythrocytes and Caco-2 cells, employed as model systems. Pretreatment of cells with various OOPEs, indeed, provides a remarkable protection against oxidative damages: this effect was strictly dependent on the o-diphen...

background: essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. objective: the antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storage. metho...

Ebselen has a wide spectrum of interesting therapeutic actions including antioxidant, cytoprotective, neuroprotective and anti-inflammatory activities. Since its antioxidant effect is very well known, this paper links the effects of ebselen in redox cellular status to its possible involvement in the maintenance of the integrity of genomic information by using Saccharomyces cerevisiae strains pr...
