Clinical trials and animal studies have suggested that lycopene, the red carotenoid found in tomatoes, might be useful for the prevention of prostate cancer in the diet or as a dietary supplement through a variety of chemoprevention mechanisms. As most mechanism of action studies have used prostate cancer cells or males with existing prostate cancer, we investigated the effects of lycopene on p...

OBJECTIVE Furan (C4H4O) is a heat-induced food contaminant that is utilized as an industrial chemical agent. Lycopene is a natural substance that is produced by plants and tomatoes. We aimed to evaluate the toxicity of furan on testes and the protective effect of lycopene in diabetic rats. MATERIAL AND METHODS Male Wistar albino rats were divided into five groups: Group 1 (control group) rece...

The present study was carried out to enhance shelf life of pasteurized cream using Echinophora platyloba essential oil (EEO) and lycopene. For this purpose, two concentrations of EEO (0.10% and 0.50%) and lycopene (20 and 50 ppm) alone and together as combinations were added in pasteurized creams and analyzed for microbial characteristics, sensorial properties and lipid stability durin...

An experiment was conducted to determine the effect of lycopene on lipid profile and quality of meat of broiler chickens Ross 308 at a different form of selenium. 540 broiler cockerels were randomly divided into 6 groups: without lycopene supplement (groups C and E3), supplemented with 50 mg/kg lycopene (groups E1 and E4), supplemented with 100 mg/kg lycopene (groups E2 and E5) while the source...

consumption of tomato products and supplements with a concomitant decrease in the biomarkers of oxidation including the oxidation of serum lipids, LDL cholesterol, serum proteins and DNA. No adverse effects were observed in this study up to a daily intake of 150 mg lycopene for one week (6). Recent studies have shown that ingested lycopene is metabolized in the body. Several metabolites have no...

Obesity is associated with increased liver cancer risks and mortality. We recently showed that apo-10'-lycopenoic acid, a lycopene metabolite generated by beta-carotene-9',10'-oxygenase (BCO2), inhibited carcinogen-initiated, high-fat diet (HFD)-promoted liver inflammation, and hepatic tumorigenesis development. The present investigation examined the outstanding question of whether lycopene cou...

The aim of this study was to investigate the possible protective role of lycopene on cisplatin (CP)-induced spermiotoxicity using quantitative, biochemical and histopathological approaches. Adult male Sprague-Dawley rats were randomly divided into four groups. The control group received physiological saline; animals in cisplatin group received only cisplatin; pre-treatment group received a 10-d...

Lycopene in tomatoes and tomato products is routinely determined by extraction into organic solvents and spectrophotometric quantification. The direct determination of lycopene, by measuring the color or other optical properties of a tomato homogenate, would be an attractive alternative. We have evaluated two instruments for this purpose. The color of tomatoes and tomato products is routinely d...

Prostate cancer is the most common cancer in American men. Preventable measures for this malignancy are not well established. Among potentially beneficial natural compounds is the carotenoid lycopene, which is derived largely from tomato-based products. Recent epidemiologic studies have suggested a potential benefit of this carotenoid against the risk of prostate cancer, particularly the more l...

OBJECTIVE To evaluate the effect of pre-natal supplementation of antioxidant Lycopene in prevention of pre-eclampsia in the high risk pregnant women. We also assessed the effect of lycopene supplementation on intra-uterine growth restriction and the perinatal outcome in women at high risk of developing pre-eclampsia. MATERIALS AND METHODS A total of 54 women between 14-28 weeks of pregnancy w...
