alpha-carotene

05/01/1999 - "These data suggest that plasma levels of alpha-carotene and gamma-tocopherol may represent markers of atherosclerosis in humans. "
05/01/1999 - "Lipophilic antioxidants in blood plasma as markers of atherosclerosis: the role of alpha-carotene and gamma-tocopherol."
01/01/2000 - "No association with atherosclerosis was observed for quartiles of serum concentrations of alpha-carotene, beta-carotene, lutein, and zeaxanthin. "
02/01/2004 - "These findings suggest that higher levels of plasma oxygenated carotenoids (lutein, zeaxanthin, beta-cryptoxanthin) and alpha-carotene may be protective against early atherosclerosis."
05/01/1999 - "In order to assess whether the levels of lipophilic antioxidants in human plasma can discriminate between subjects with and without atherosclerosis, we measured the lipophilic antioxidants alpha-tocopherol, gamma-tocopherol, alpha-carotene, beta-carotene and ubiquinol-10 in plasma of 34 patients with coronary heart disease (CHD) and in 40 control subjects. "

01/01/2010 - "The results of this review showed that various vitamins (vitamin C, D, E, A, beta and alpha carotene) are associated with improvement in features of COPD such as symptoms, exacerbations and pulmonary function. "

08/01/2001 - "Plasma vitamin A, alpha-carotene, beta-carotene, lycopene, lutein/zeaxanthin, and vitamin E were depressed at enrollment and increased by day 7. Multivariate analyses showed that higher plasma lycopene concentrations at enrollment were associated with clearance of parasitemia between enrollment and day 3 (odds ratio = 1.46, 95% confidence interval = 1.07-2.06, per 0.10 micromol/L of lycopene). "

01/01/2013 - "Alpha-carotene, lycopene, and beta-cryptoxanthin showed protection against esophageal squamous cell cancer. "

01/01/1995 - "Oral administration of alpha-carotene (0.05% in drinking water) significantly decreased the mean number of lung tumors per mouse. "
01/01/1995 - "In the two-stage mouse skin carcinogenesis model (initiator, 7,12-dimethylbenz[a]anthracene; promoter, 12-O-tetradecanoylphorbol-13-acetate), topical application of alpha-carotene at a 200 nmol dose per painting twice a week significantly decreased the mean number of skin tumors per mouse. "
12/01/1992 - "alpha-Carotene, but not beta-carotene, reduced the number of lung tumors per mouse to about 30% of that in the control group (P < 0.001, Student's t test). "
01/15/2005 - "The inverse association observed with alpha-carotene and breast cancer was greater for invasive cancers with nodal metastasis. "
