We tested the hypothesis that dietary fibre (DF) has protective effects against manganese (Mn)-induced neurotoxicity. Forty-eight one-month old Sprague-Dawley rats were randomly divided into six groups: control, 16 % DF, Mn (50 mg kg-1 body weight), Mn+ 4 % DF, Mn+ 8 % DF, and Mn+ 16 % DF. After oral administration of Mn (as MnCl2) by intragastric tube during one month, we determined Mn concent...

BACKGROUND Dietary intake of ω3 polyunsaturated fatty acids (ω3-PUFAs) reduces progression of atherosclerosis and prevents future cardiovascular events. Macrophages are key players in the pathogenesis of aortic aneurysm. The effects of ω3-PUFAs on abdominal aortic aneurysm (AAA) formation and macrophage-mediated inflammation remain unclear. METHODS AND RESULTS: The AAA model was developed by an...

Lactobacillus brevis was isolated from the intestinal tract of Sander lucioperca and its immunological parameters as well as intestinal morphology were studied. Thereafter, the fish were challenged with 4.5×108 CFU/g Aeromonas hydrophila. The fish were monitored daily and the rate of survival was recorded over a period of 7 days post-challenge. The results showed that feeding with supplemented ...

The effects of varying dietary protein concentrations on the metabolism of 1,2-dimethylhydrazine (DMH) to mutagenic prod ucts by male C57BL/6 x C3H F, mice were assayed by in vivo and in vitro methods. DMH and its metabolite, azoxymethane (AOM), did not increase the mutation frequency of Salmonella typhimurium (strain G-46) in vitro alone or in the presence of mouse liver homogenates capable of...

Poly-trans-[(2-carboxyethyl) germasesquioxane] (Ge-132) is the most common organic germanium compound. The ingestion of Ge-132 promotes bile secretion. We assessed the rat caecal characteristics after the administration of Ge-132 and raffinose, a prebiotic oligosaccharide, because both Ge-132 and some prebiotics can change the fecal color to yellow. We also compared the changes in the caecal fl...

The effects of varying dietary protein concentrations on the metabolism of 1,2-dimethylhydrazine (DMH) to mutagenic products by male C57BL/6 X C3H F mice were assayed by in vivo and in vitro methods. DMH and its metabolite, azoxymethane (AOM), did not increase the mutation frequency of Salmonella typhimurium (strain G-46) in vitro alone or in the presence of mouse liver homogenates capable of a...

The Healthy Beverage Index (HBI) is an emerging approach to assess beverage pattern quality. HBI total scores range from 0 to 100, with higher scores indicating greater adherence to proposed beverage recommendations. However, assessing patterns is resource-intensive due to the need for extensive dietary data, typically 24-h dietary records or recalls. The BEVQ-15, a beverage intake questionnair...

This study demonstrated the effect of the simultaneous dietary administration of fish protein and fish oil, two macronutrients found in fish meat, on cholesterol metabolism in rats. Male Wistar rats were divided into four groups and fed an AIN-93G modified hypercholesterolmic diet with casein (20%) + soybean oil (7%), casein (10%) + fish protein (10%) + soybean oil (7%), casein (20%) + soybean ...

The increased requirement for vitamin Blz in thyrotoxic animals is well established (l-3). Vitale et al. (4) have demonstrated that magnesium will also partially overcome the growth-inhibiting action of thyroxine administration. Uncoupling of oxidative phosphorylation occurs in rats made magnesium-deficient either by dietary deprivation of magnesium (5) or by thyroxine administration (4). In vi...
