beta cryptoxanthin/infarction

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

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

β-Cryptoxanthin and astaxanthin are antioxidant carotenoid pigments that inhibit lipid peroxidation as potently as vitamin E. We hypothesized that acute treatment with β-cryptoxanthin and astaxanthin causes similar reductions in the sizes of cardiac infarcts caused by ischemia-reperfusion (I/R)

The present study aimed to explore the function and molecular mechanism of β-cryptoxanthin on myocardial ischaemia-reperfusion injury (MIRI). Left anterior descending coronary artery ligation with reperfusion was utilised to establish a MIRI rat model. The results indicated that β-cryptoxanthin

BACKGROUND Neither macro- nor micronutrient supplements have been clearly demonstrated to reduce the risk of preterm birth. However, there has been little attention to carotenoids, tocopherols, and long-chain fatty acids other than n-3 polyunsaturates. METHODS We conducted a case-control study

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

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

Systemic inflammation, oxidative stress, and atrial fibrosis are identified as the main mechanisms for atrial fibrillation (AF). Antioxidant micronutrients may have antiarrhythmic benefit in humans. We studied whether plasma carotenoids are related to the risk of AF in elderly subjects. The study
