Women show higher vitamin C plasma concentrations than men, but the reasons for this observation still require elucidation. The objective of the present study was to investigate whether sex differences in vitamin C plasma concentrations are present in elderly subjects and whether these differences are due to sex-specific lifestyles, total antioxidant status (TAOS) and/or body composition. Fasti...
background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...
Introduction: According to studies, high intake of fruits and vegetables are associated with reduced cancer incidence and mortality. The high levels of antioxidants in fruits and vegetables are believed to contribute in cancer prevention, possibly by inhibiting oxidative stress. This study aimed to investigate the effects of cigarette smoke, alcohol and vitamin E and vitamin C on oral mucosa an...
Background: Oxidative modification of low-density lipoprotein (LDL) appears to be an early step in the pathogenesis of atherosclerosis. Meanwhile, myeloperoxidase (MPO)-catalyzed reaction is one of the potent pathway for LDL oxidation in vivo. The aim of this study was to evaluate in vitro antioxidant effects of vitamins C and E on LDL oxidation mediated by MPO. Methods: MPO was isolated from f...
Hyperoxaluria and oxidative stress are risk factors in calcium oxalate (CaOx) stone formation. Supplement with antioxidant could be effective in prevention of recurrent stone formation. The present study aims to evaluate the protective effects of vitamin E and vitamin C in hyperoxaluric rat. The experiment was performed in rats for 21 days. Rats were divided into 5 groups as follows: control (g...
Background and Objective: Improvement of vitamin D status can lead to cardiovascular health. Therefore, the objective of this study was to investigate effects of daily consumption of fortified canola oil with 1000 IU of vitamin D on serum concentrations of 25-hydroxy cholecalciferol and lipid profile of adults in Shiraz, Iran. Materials and Methods: In this double-blind randomized trial, a tot...

The ellagic acid, total phenolic, and vitamin C contents in four raspberry cultivars (Heritage, Autumn Bliss, Rubi, and Zeva) grown in Spain were detected and quantified by HPLC in fresh, just frozen, and stored fruits at -20 degrees C for a one year period. Ellagic acid [207-244 mg kg(-)(1) of fresh weight (fw)], total phenolic (137-1776 mg kg(-)(1) of fw), and vitamin C (221-312 mg kg(-)(1) o...
