| Los altos niveles de ácidos grasos saturados en la carne de rumiantes representan un punto crítico en la alimentación humana por su relación con enfermedades cardiovasculares. La levadura Saccharomyces cerevisiae (Sc) es rica en ácido oleico y representa una alternativa para modificar el perfil de ácidos grasos de la carne, al incrementar la proporción de ácidos grasos insaturados. Por lo anterior, se realizó un experimento con corderos en crecimiento (20± 0.9 kg PV), utilizando una dieta a base de concentrado y tres niveles (tratamientos, T) de Sc (0, 3 y 5 g animal-1 d-1, T1, T2 y T3, respectivamente), con el objetivo de determinar el comportamiento animal, caracterizar la fermentación ruminal, los niveles plasmáticos de colesterol y los ácidos grasos... |

| Recombinant CHO TF70R cells are able to grow and produce t-PA on serum-free medium BIOPRO1 (BioWhitaker Europe, Belgium). The purpose of the present study was to determine the effect of medium supplementation with vitamins, lipids, and specific amino acids on cell growth, t-PA production and biological functionality. Among vitamins, only biotin, folic acid, cobalamine and benzoic acid were required for improving growth and t-PA production. Lipid supplement allowed a significant increase cell concentration and t-PA specific activity and concentration, though its specific production rate decreased slightly. Medium supplementation with proline, serine and asparagine had also positive effects on cell growth. Besides, the addition of asparagine (even in the... |

| In this work, we examined the impact of polymorphism in the cytochrome P450 (CYP) 3A5 gene, CYP3A5*1 (6986A > G, rs 776746), on the reduction in the lipid levels caused by simvastatin and atorvastatin. We studied 350 hyperlipidemic patients who received 10-40 mg of atorvastatin (n = 175) or simvastatin (n = 175) daily. Genotyping for CYP3A5 was done by PCR-RFLP analysis. Differences in the lipid profile before and after treatment were expressed as the % difference. The frequency of CYP3A5 polymorphism was 13.4% for heterozygotes and 86.6% for homozygotes. Comparison of the responses to same dose of each drug showed that the highest % difference was associated with total cholesterol (TC) in subjects receiving atorvastatin 40 mg compared with simvastatin... |

| A carne bovina magra e considerada um alimento de alta densidade nutricional, por apresentar em sua composicao uma grande quantidade de nutrientes, com alta disponibilidade e baixo valor calorico. Ela e rica em proteinas de alta qualidade, acidos graxos essenciais, vitaminas do complexo B (tiamina, riboflavina, niacina, biotina, acido pantotenico, folacina, vitaminas B6 e B12) e minerais como ferro, zinco e fosfora. Todos os nutrientes contidos na carne bovina sao de primordial importancia na alimentacao, destancando-se o ferro. Na carne bovina, o ferro e encontrado na forma heme, de mais facil absorcao pelo organismo humano do que o ferro nao heme, disponivel nos vegetais, cereais, frutas e ovos. No entanto, por ignorancia ou sensacionalismo, informacoes... |

| A review of lipid requirements of shrimp and other crustacean species, when applicable, is presented. Qualitative requirements of crustaceans for cholesterol, fatty acids and phospholipids have been documented, but quantitative requirements generally remain undefined. Potential interrelationships between different classes of lipids that may influence requirements as well as differences due to age and species need to be investigated. A more accurate definition of lipid requirements can be achieved by supporting traditional evaluations based upon weight gain and survival with biochemical or histological evidence. |

| Partial or total replacement of fish meal by a mixture of plant protein (PP) sources (corn gluten, wheat gluten, extruded peas, rapeseed meal and sweet white lupin) balanced with indispensable amino acids was examined in juvenile gilthead sea bream over the course of a 6-month growth trial. A diet with fish meal (FM) as the sole protein source was compared to diets with 50%, 75% and 100% of replacement (PP50, PP75, and PP100). The possible influence of diets on growth performance, plasma metabolites, gut integrity, liver structure, anti-oxidant and immune status was evaluated. Final body weight was progressively decreased with PP inclusion, but in PP50 and PP75-fed fish, feed efficiency (FE) was significantly improved and specific growth rates remained... |

| Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris (T. terrestris) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n=6). Animals in experimental groups were received high fructose diet (70 %) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also... |

| This study evaluated whether a high fat diet (HFC group) induces overweight, hepatic steatosis and plasma lipoproteins level alteration compared to standard chow diet (SC group). Female mice were submitted to each diet over 6 months. Body mass and food intake were evaluated weekly throughout the experiment. Total cholesterol, TG, LDL-c, HDL-c and VLDL-c were analyzed. Mice were sacrificed to remove liver, spleen, heart and intestine. The volume of the organs was determined according to the submersion method. Fixed livers were embedded in paraffin and stained with hematoxylin and eosin and Masson's trichrome. The analysis used a video microscope system and a test-system with 42 test-points. The volume density was estimated for hepatocytes, steatosis and... |

| The intracellular protozoan Toxoplasma gondii lacks the ability to synthesize sterol and scavenges cholesterol from the lowdensity lipoprotein receptor (LDLR) pathway of its host to facilitate replication. Sterol biosynthesis inhibitors, however, have a demonstrated anti-Toxoplasma effect. In this study, we examined the host mevalonate pathway as a novel source of cholesterol for T. gondii and its effects on parasite growth in macrophages. Parasite growth did not significantly change in the absence of LDLR or when LDL was exogenously supplemented. Lovastatin and compactin, both inhibitors of hydroxymethylglutaryl-CoA (HMG-CoA) reductase in the mevalonate pathway, significantly inhibited T. gondii growth in both wild-type and LDLR-knockout macrophages.... |

| In this study we compared the hypocholesterolaemic ability of two potato peptide preparations in rats. Experimental groups were fed for 4 weeks, with casein as the basal diet, in comparison with two diets containing 20% potato peptide preparations PPS (Short hydrolysis preparation) and PPL (Long hydrolysis preparation). Serum total cholesterol and serum triglyceride level were lower in PPS-fed group compared with CN-and PPL-fed groups. Lower non-HDL cholesterol level (P<0.05) in both PPS-and PPL-fed groups, was followed by higher neutral sterol excretion, and higher hepatic LDL-R and SR-B1 mRNA level than the control. Hepatic SREBP-2 and HMG-CoA reductase mRNA level were higher in PPL-fed group compared with the CN-fed group (P<0.05). Caecal total... |

| We examined the effects of Amylomyces rouxii, which is a mold found in some fermented foods in Indonesia, on serum cholesterol and hepatic LDL receptor mRNA in rats. Rats were fed a 0.5% cholesterol-enriched diet with (A. rouxii group) or without (control group) 30g/kg A. rouxii for 4 wk. There were no significant differences in the body weight, food intake or liver weight among the groups. However, the weight of the cecum in the A. rouxii-fed group was significantly higher than that in the control group. The cecal pH in the A. rouxii-fed group was significantly lower than that in the control group. Cecal acetic acid, propionic acid and total SCFA concentrations in the A. rouxii-fed group were significantly higher than those in the control group. The serum... |
