The aim of this study was to evaluate the effects of an oral supplementation with a Curcuma longa ethanol and aqueous extract on the susceptibility to oxidation of cellular and subcellular membranes affected in the atherosclerotic process, such as erythrocyte membranes and liver microsomes, in rabbits fed with a high-fat diet. ⋯ The results of this study indicated that oral administration of a nutritional dose of C. longa extracts reduces the susceptibility to oxidation of erythrocyte and liver microsome membranes in vitro and may contribute to the prevention of effects caused by a diet high in fat and cholesterol in blood and liver during the development of atherosclerosis.

We investigated the effects of conjugated linoleic acid (CLA) on tumor incidence, apoptosis, eicosanoid formation, 1,2-diacylglycerol (DAG), and fatty acid profiles of colonic mucosa in 1,2-dimethylhydrazine-treated rats fed different types of dietary fats. ⋯ These results suggested that increased apoptosis by dietary CLA may be attributed, at least in part, to changes in arachidonic acid metabolism in rats. Therefore, CLA may have anticarcinogenic effects by inducing apoptosis through modification of signal transduction in colonic mucosal cells.

We assessed quality of life (QOL) in patients on home enteral tube feeding (HETF). The data should contribute to ethically justified decision making. ⋯ . Measures of QOL research can be used in HETF patients. QOL is reduced in patients on HETF. Part of this effect is explained by malnutrition. HETF can prevent further weight loss and improve some aspects of QOL, thus allowing physicians to focus on patients.
