| The aim of this work was to determine the sugar, organic acid and mineral compositions of the whole fruit and fractions (skin, pulp and seed) of the Paulista (Plinia cauliflora) and Sabará (Plinia jaboticaba) jabuticaba tree genotypes, as well as the oil compositions of their skin and seeds. High levels of sugar, especially fructose, followed by glucose and sucrose, were encountered in the fruit. In the Paulista genotype, higher levels of total and reducing sugars were found in the pulp and skin, which was not observed when comparing the whole fruit of both genotypes. Five organic acids were found in the whole fruit and in the fractions of the two jabuticaba genotypes in quantitative order: citric acid > succinic acid > malic acid > oxalic acid... |

| In obstructive jaundice, the passage of bacteria and endotoxins through the intestine wall to reach the systemic circulation is associated with septicemia, renal failure and pulmonary dysfunction. The aim of this work was to investigate bacterial translocation utilizing 99mTc-E.coli in an experimental model of obstructive jaundice. The levels of bilirubin in rats that were subjected to ligature of the bile duct were significantly increased when compared to control animals (p < 0.001). The biodistribution results did not show any translocation of 99mTc-E.coli to the mesenteric lymphatic nodules, liver, spleen or lungs of the rats that suffered ligature of the bile duct (p > 0.05). The evaluation of the intestinal permeability using "per os"... |

| The effects of the use of a protein concentrate as a fat substitute on the quality of cheese bread were investigated. Based on a 10% basic fat formulation, the substitution of 10, 25, 50, 75 and 100% of the oil in the formula was tested. Physical characteristics were measured, and sensorial parameters were determined. The products with lower levels of fat substitute had higher levels of acceptability. With the increase in the degree of substitution, the cheese bread products were harder, had a thicker crust and presented a less pleasant appearance, less pronounced cheese flavor and a lower degree of acceptance. The use of a fat substitute resulted in a product with a significantly lower fat content and a caloric reduction greater than 25%. |

| The mangaba (Hancornia speciosa) stands out and has a great potential for economic exploitation and researches have suggested relevant results regarding the nutritional and functional value of this food. Therefore, the objective of this study was to chemically and physicochemically characterize the mangaba fruit harvested in the Middle Araguaia region. It was evaluated the chemical composition, antioxidant activity, volatile compounds, preliminary photochemical studies of phenolic components and the cytotoxic potential of ethanolic extract fruits against Artemia salina. The mean pH, the total titratable acidity and the value for reducing sugars conclude that the mangaba possesses the characteristics appropriate for both fresh consumption and for... |

| In this research it was studied the influence of the radiation intensity on growth and on the essential oil yield of Baccharis trimera. The plants growth was studied under four levels of radiation: 100, 60, 50 and 20% during a 259-day long period. Plants were then evaluated for height, number of nodes, branches, stem diameter (at the height of the colon), biomass formation, and content and composition of the oil. The highest level of radiation caused increases in all of the variables evaluated, except for height, which was reduced with increasing radiation. Essential oil content also increased with increasing level of radiation. |
