The effect of individual administration of low doses of highly purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (1 g/kg body weight) on the growth of Morris hepatocarcinoma 3924A transplanted in ACI/T rats was investigated. Both EPA and DHA inhibited growth of the hepatocarcinoma (50% reduction of tumor weight or volume at the 19th day(More)
Subjects at high risk for colon cancer received different doses of fish oil on a 30-day randomized double-blind trial to evaluate the chemopreventive effect of n-3 fatty acids against colorectal cancer. Using rectal mucosal proliferation, assessed with 3H-thymidine autoradiography, fish oil induced in the treated groups but not in the placebo group a change(More)
In view of the promising future for use of n-3 polyunsaturated fatty acids (PUFA) in the prevention of cancer and cardiovascular diseases, it is necessary to ensure that their consumption does not result in detrimental oxidative effects. The aim of the present work was to test a hypothesis that low doses of eicosapentaenoic acid (EPA) or docosahexaenoic(More)
Supplementation with low doses of eicosapentaenoic (EPA) or docosahexaenoic (DHA) acid was used here to investigate changes in epithelial proliferation, differentiation, and apoptosis in normal rat colonic mucosa. ACI/T rats received by oral administration low doses of purified EPA or DHA ethyl esters (1 g/kg body weight) and colonic mucosa was analyzed for(More)
The effects of long-term treatment with a high dose (7.7 g/day) of n-3 polyunsaturated fatty acids (PUFA) were studied for human red blood cells (RBCs). RBCs isolated from healthy subjects treated for 30 and 180 days with n-3 PUFA showed the following modifications: (1) a time dependent modification of membrane fatty acid composition with a concomitant(More)
Age-related macular degeneration (AMD) is the most common cause of irreversible visual impairment among people over 50 years of age, accounting for up to 50% of all cases of legal blindness in Western countries. Although the aging represents the main determinant of AMD, it must be considered a multifaceted disease caused by interactions among environmental(More)
The present work was performed to study an optimal dose and duration of dietary n-3 polyunsaturated fatty acid (PUFA) supplementation that would not result in harmful modifications of oxidative cell metabolism. Forty healthy subjects were divided into four groups that received 2.5 g/d eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA), 5.1 g EPA +(More)
Nonsyndromic cleft lip with or without cleft palate (NSCL/P), the most common type of orofacial clefting, is one of the most frequent congenital defects. Based on epidemiological data, NSCL/P can be distinguished from nonsyndromic cleft palate only (NSCPO). Both phenotypes have a complex etiology and environmental and genetic factors are involved in their(More)
The purpose of this study was to determine whether individual administration of highly purified eicosapentaenoic acid (EPA), one of the main components of the n-3 polyunsaturated fatty acid family, would alter the growth of focal lesions during hepatocarcinogenesis. The protocol used to induce chemical carcinogenesis in liver was the Solt-Farber model(More)
