OBJECTIVE
Modification of low-density lipoprotein due to oxidative stress is essential in the development of coronary atherosclerosis. Data of specific carotenoids except β-carotene on cardioprotective effects in humans are limited.
RESULTS
This study examined the associations between plasma
Antioxidants, particularly carotenoids and tocopherols, may protect against cardiovascular disease. The objective of this study was to determine whether dietary and adipose tissue carotenoids and tocopherols are associated with the risk of myocardial infarction (MI). Cases (n = 1456) of a first
BACKGROUND
In vitro, animal and epidemiological studies suggest that lipoprotein oxidation may play an important role in atherosclerosis. Antioxidants may protect against lipoprotein oxidation and in that way inhibit atherosclerosis and its clinical sequelae. To investigate this possibility, we
OBJECTIVE
Epidemiologic studies have suggested that dietary intake and plasma concentrations of antioxidants have an inverse relation with coronary heart disease. To test whether fat-soluble antioxidants can play a role against the occurrence of myocardial infarction (MI), we measured plasma levels
BACKGROUND
Increased intake of carotenoids and vitamin E may protect against myocardial infarction (MI). However, prospective data on blood levels of carotenoids other than beta-carotene and vitamin E (tocopherol) and risk of MI are sparse.
RESULTS
We conducted a prospective, nested case-control
BACKGROUND
Carotenoids may reduce the risk of coronary heart disease through their antioxidant properties, but the results of epidemiological studies are controversial. We analysed the relation between the intake of selected carotenoids and retinol and risk of acute myocardial infarction
Trans sodium crocetinate (TSC) is a synthetic small-molecule antioxidant that has the ability to enhance oxygen diffusion to hypoxic tissue. Because TSC is a promising drug candidate to treat acute ischemic stroke (AIS), we tested the hypothesis that TSC may be neuroprotective following cerebral
OBJECTIVE
Previous studies have shown that high intake or concentrations of serum carotenoids may protect against acute myocardial infarction (AMI). The role of carotenoids on the risk of AMI remains inconsistent. The aim of the present study was to examine if serum concentrations of major
Biomarkers of dietary exposure or nutritional status are sought actively to overcome limitations of traditional dietary methodology. We compared plasma and adipose tissue biomarkers for carotenoids and tocopherols. The data consisted of samples from 91 men and 122 women, ages 45-70 years, from the
BACKGROUND
Emerging evidence suggests a possible role of lycopene in the primary prevention of cardiovascular disease (CVD).
OBJECTIVE
We examined whether plasma lycopene concentrations in the Physicians' Health Study were associated with CVD in a prospective, nested, case-control
Lycopene, a carotenoid rich in tomato fruit (ripe), is an effective antioxidant and free radical scavenger. In this study n-hexane extract of tomato was evaluated for its protective action against oxidative stress in experimental myocardial infarction induced by administration of adrenaline in rats.
OBJECTIVE
To examine the relationship between total serum carotenoid levels and the risk of subsequent coronary heart disease (CHD) events.
METHODS
New analysis of a cohort from the Lipid Research Clinics Coronary Primary Prevention Trial and Follow-up Study (LRC-CPPT). The LRC-CPPT was a
BACKGROUND
Numerous studies have shown that higher intakes or higher blood concentrations of carotenes are associated with a lower risk of coronary artery disease (CAD). Given the null results in trials of beta-carotene supplementation, considerable attention has focused on the potential role of
OBJECTIVE
To study relationships between habitual dietary intake, adipose tissue concentrations of alpha-carotene, beta-carotene and lycopene, and plasma concentrations of alpha- and beta-carotene.
METHODS
Cross-sectional study including assessment of food habits by a food frequency questionnaire
BACKGROUND
Antioxidants increase the resistance of low-density lipoprotein to oxidation and may thereby reduce risk for atherosclerosis.
OBJECTIVE
To determine whether intake of vitamin E, vitamin C, or carotenoids predict risk for total or ischemic stroke.
METHODS
Prospective observational
