The effect of alpha-tocopherol on the oxidative cleavage of beta-carotene
(Elsevier B.V., 2000-07-15)
Two cleavage pathways of beta-carotene have been proposed, one by central cleavage and the other by random (excentric) cleavage. The central cleavage pathway involves the metabolism of beta-carotene at the central double ...
Radioprotection of beta-carotene evaluated on mouse somatic and germ cells
(Elsevier B.V., 1996-09-23)
In the present paper, the protective effect of beta-carotene was evaluated after whole body exposure of mice to 2 Gy of X-rays. Splenocytes, reticulocytes, bone marrow cells and spermatids were evaluated for the frequency ...
beta-carotene and other carotenoids as antioxidants
(Amer Coll Nutrition, 1999-10-01)
Carotenoids are natural pigments which are synthesized by plants and are responsible for the bright colors of various fruits and vegetables. There are several dozen carotenoids in the foods that we eat, and most of these ...

β-carotene attenuates the paradoxical effect of tobacco smoke on the mortality of rats after experimental myocardial infarction
(2005-09-01)
The objective of this study was to investigate the effects of exposure to tobacco smoke (ETS) in rats that were or were not supplemented with dietary β-carotene (BC), on ventricular remodeling and survival after myocardial ...
Correlation between carotenoid concentrations in serum and normal breast adipose tissue of women with benign breast tumor or breast cancer
(1998-11-01)
To evaluate the relationship between carotenoid concentrations in serum and breast tissue, we measured serum carotenoid concentrations and endogenous carotenoid levels in breast adipose tissue of women with benign breast ...
beta-carotene attenuates the paradoxical effect of tobacco smoke on the mortality of rats after experimental myocardial infarction
(Amer Society Nutritional Science, 2005-09-01)
The objective of this study was to investigate the effects of exposure to tobacco smoke (ETS) in rats that were or were not supplemented with dietary beta-carotene (BC), on ventricular remodeling and survival after myocardial ...
Beta-carotene supplementation attenuates cardiac remodeling induced by one-month tobacco-smoke exposure in rats
(Oxford University Press, 2006-03-01)
Objective: the objectives were to analyze the cardiac effects of exposure to tobacco smoke (ETS), for a period of 30 days, alone and in combination with beta-carotene supplementation (BC). Research methods and procedures: ...
Dietary predictors of serum total carotene in low-income women living in São Paulo, south-east Brazil
(Cambridge Univ Press, 2009-11-01)
Objective Dietary intake and nutritional status of antioxidant vitamins have been reported to protect against some cancers the objective of the present study was to assess the correlations between serum levels of carotenoids ...
β-Carotene supplementation results in adverse ventricular remodeling after acute myocardial infarction
(2006-02-01)
Objective: We studied the effects of β-carotene (BC) on ventricular remodeling after myocardial infarction. Methods: Myocardial infarction was induced in Wistar rats that were then treated with a BC diet (500 mg/kg of diet ...
