Plasma vitamin C, but not vitamin E, is associated with reduced risk of heart failure in older men.
BACKGROUND Oxidative stress has been implicated in the pathogenesis of heart failure (HF). However, data on the association between antioxidant intakes and circulating levels and risk of incident HF in the older general population are limited. We have examined prospectively the associations between plasma vitamin C and E, dietary intakes of vitamin C and E, and incident HF. METHODS AND RESULT...

متن کاملFaster plasma vitamin E disappearance in smokers is normalized by vitamin C supplementation.
Vitamin E disappearance is accelerated in cigarette smokers due to their increased oxidative stress and is inversely correlated with plasma vitamin C concentrations. Therefore, we hypothesized that ascorbic acid supplementation (500 mg, twice daily; 2 weeks) would normalize smokers' plasma alpha- and gamma-tocopherol disappearance rates and conducted a double-blind, placebo-controlled, randomiz...
متن کاملVitamin E secretion by Caco-2 monolayers to APOA1, but not to HDL, is vitamer selective.
The aim of this study was to characterize the pathways of basolateral secretion of common dietary tocopherols from polarized Caco-2 monolayers, a model of intestinal absorption. Given differences in structure and physical properties, we hypothesized that secretion may differ between different forms of vitamin E, thus potentially contribute to the selectivity seen in vivo. Monolayers were incuba...
متن کاملVitamin D: Is There a New Era?
Background: In recent decades, much interest has been focused on investigating new roles of vitamin D in human body beyond the mineral-ion homeostasis. Methods: By searching medical databases such as PubMed, over 16000 articles were found which have been published since 2000 on novel aspects of vitamin D in health and diseases. Results: Of great interest was the effects of vitamin D on ...
