The effect of lycopene on serum nitrate-nitrite levels was investigated in diabetic rats. In this investigation, 28 Wistar rats were divided into 4 groups, each of seven rats. These groups were control group, diabetes group, diabetes-lycopene group and lycopene group. The concentration of nitrite and nitrate was detected at high levels in diabetes group, diabetes-lycopene group and lycopene gro...

This report details the findings of a single-dose Phase I pharmacokinetic and toxicity study of a food-based formulation of lycopene in healthy adult male subjects. Five dosing groups (n = 5 per group) were sequentially treated with increasing doses of lycopene ranging from 10 to 120 mg. Blood samples were collected for a total of 28 days (672 h) after administration of single doses of lycopene...

An evaluation of the Health Professionals Follow-Up Study has detected a lower prostate cancer risk associated with the greater consumption of tomatoes and related food products. Tomatoes are the primary dietary source of lycopene, a non-provitamin A carotenoid with potent antioxidant activity. Our goal was to define the concentrations of lycopene, other carotenoids, and retinol in paired benig...

Lycopene has been shown to be associated with anticancer effects in numerous tumor types. However, the underlying mechanisms of lycopene in human head and neck squamous cell carcinoma (HNSCC) remain to be determined. The present study aimed to investigate the involvement of lycopene overload and the cytotoxic effects of lycopene on HNSCC cells, and to determine the possible mechanisms involved....

UNLABELLED Background/aim: To determine the efficacy of lycopene, which is considered an antioxidant agent, in decreasing the cochlear damage induced by cisplatin. MATERIALS AND METHODS A total of 38 rats were randomized into 4 groups: control, cisplatin, cisplatin + lycopene, and lycopene-treated groups. In all groups, the distortion-product otoacoustic emission measurements were performed o...

Lycopene is a potentially useful compound for preventing and treating cardiovascular diseases and cancers. Studies on the effects of lycopene on oxidative stress offer insights into its mechanism of action and provide evidence-based rationale for its supplementation. In this analysis, randomized controlled trials of the effects of oral lycopene supplementation on any valid outcomes of oxidative...

OBJECTIVE Lycopene is a phytochemical, found in tomatoes having singlet oxygen quenching ability higher than other antioxidants, participates in most of chemical reactions to protect critical cellular biomolecules. Present study is to analyze effect of tomato's lycopene, synthetic lycopene, its placebo form in patients of OS. METHODS Study includes 45 patients having oxidative stress, age 40-...

background: a great deal of evidence has indicated that oxidatively modified ldl plays a critical role in the initiation and progression of atherosclerosis. antioxidants that can prevent ldl oxidation may act as antiatherogens. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper ions to ldl is usually thought to be a prerequisite for ldl oxidation by copper...

Prostate cancer (PCa) is a common illness for aging males. Lycopene has been identified as an antioxidant agent with potential anticancer properties. Studies investigating the relation between lycopene and PCa risk have produced inconsistent results. This study aims to determine dietary lycopene consumption/circulating concentration and any potential dose–response associations with the risk of ...

Introduction Lycopene (C40H56), as a unsaturated red-pigmented linear carotenoid, has a molecular weight of 536.85 Da, and 11 conjugated and 2 non-conjugated double bonds; it is lipophilic and therefore more soluble in organic solvents (1-3). Lycopene is a lipid-soluble antioxidant and has been inversely associated with lipid peroxidation, comprising low-density lipoprotein oxidation and reduce...
