25. Avaliação da cor e da atividade antioxidante da polpa e extrato de mirtilo (Vaccinium myrtillus) em pó / Evaluation of coloration and antioxidant activity of powder pulp and extract from blueberry (Vaccinium myrtillus) fruits
O mirtilo (Vaccinium myrtillus) tem chamado a atenção de produtores e consumidores nos últimos anos, devido a sua qualidade nutricional e benefícios à saúde. É fonte rica de pigmentos naturais, principalmente antocianinas, e apresenta alto valor agregado devido à associação como alimento funcional. O presente trabalho teve por objetivo caracterizar

26. Re(I) complexes and TiO2 films in photoinduced molecular devices / Complexos de Re(I) e filmes de TiO2 em dispositivos moleculares fotoinduzidos
The thesis focus on two main topics: characterization of TiO2 films for Dye-sensitized solar cells, DSCs, and investigation on photochemical and photophysical properties of Re(I) polypyridyl complexes. Mesoporous TiO2 films were prepared by sol-gel method and by commercial oxide (P25, Degussa) and were characterized by XRD, SEM, B.E.T. and XPS. Both oxides w

27. Micropropagation and vegetative development of blueberry / Micropropagação e desenvolvimento vegetativo de mirtilo
Blueberry cultivation is recent in Brazil, and the area expansion of this production is limited by the lack of quality seedlings. The in vitro propagation make possible, in little time, to produce of mass form, high quality plants. In this work, the first objective was to study some involved factors in the establishment, multiplication and rooting of blueber

28. Evaluation of the in vivo mutagenic potential of hydroalcoholic extracts of the northern highbush blueberry (Vaccinium corymbosum L. Ericales, Ericaceae) on peripheral blood cells of Swiss mice (Mus musculus Rodentia, Muridae)
The northern highbush blueberry (Vaccinium corymbosum L. Ericales, Ericaceae) is very rich in anthocyanins, natural pigments which have strong antioxidant properties and potential health benefits, resulting in the worldwide use the blueberry as a medicinal plant. We investigated the mutagenic potential of simple hydroalcoholic extracts of V. corymbosum acute

29. Polinização em amoreira-preta (Rubus sp.), mirtilo (Vaccinium ashei) e ameixeirajaponesa (Prunus salicina) / Pollination in blackberries (Rubus sp.), blueberry (Vaccinium ashei) and japanese plum (Prunus salicina)
As espécies frutíferas de clima temperado têm grande importância econômica e social na região Sul e Sudeste do Brasil. Dentre as várias espécies que podem ser aí produzidas, algumas foram recentemente introduzidas no sistema produtivo da região ou tiveram pouca expansão. Enquanto no primeiro caso encontra-se o mirtilo (Vaccinium ashei Read), no ú

30. The production of blueberry seedlings by hardwood and semi-hardwood cuttings and mini-cuttings / Produção de mudas de mírtilo através de estacas lenhosas, semilenhosas e miniestacas
Blueberry cultivation is very recent in Brazil. The area expansion of this production is limited by the lack of quality seedlings The purpose of this research was to increase the amount of blueberry seedlings by developing and adapting propagation techniques economically feasible. Furthermore, to verify the effect of IBA (indolbutyric acid) on rooting of bot

31. In vivo evaluation of the mutagenic potential of the Vaccinium corymbosum (blueberry) extract on peripheral blood cells of Swiss mice / Investigação do potencial mutagênico do extrato de frutos de Vaccinium corymbosum (mirtilo) em células do sangue periférico de camundongos Swiss in vivo
Vaccinium corymbosum é um vegetal muito rico em antocianinas que tem uma grande capacidade antioxidante e outros potenciais benefícios à saúde e por este motivo é altamente utilizado no mundo inteiro como planta medicinal Neste trabalho foi analisado o potencial mutagênico da administração aguda do extrato bruto de frutos desta planta em células de

32. Proanthocyanidin from Blueberry Leaves Suppresses Expression of Subgenomic Hepatitis C Virus RNA*
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease such as chronic hepatitis, cirrhosis, and hepatocellular carcinoma. While searching for new natural anti-HCV agents in agricultural products, we found a potent inhibitor of HCV RNA expression in extracts of blueberry leaves when examined in an HCV subgenomic replicon cell culture sys

33. Psychrophilic and Mesophilic Fungi in Fruit-Filled Pastries
Surveys of the mold flora of frozen blueberry and cherry pastries were undertaken. Molds were enumerated by preparing pour plates of the blended product and incubating the plates at 0, 5, 10, and 20 C. In this manner, the total fungal content of the product could be ascertained from the 10 and 20 C plates, and the psychrophilic fungal population was represen

34. Psychrophilic and Mesophilic Fungi in Frozen Food Products
The mold flora of certain frozen pastries and chicken pies was investigated. Molds were determined qualitatively or quantitatively, or both, by preparing pour plates of the blended product and incubating the plates at various temperatures. The mesophilic fungal flora developed on plates incubated at 10 and 20 C, whereas psychrophilic fungi were obtained on p

35. Involvement of Peroxidase and Indole-3-acetic Acid Oxidase Isozymes from Pear, Tomato, and Blueberry Fruit in Ripening
Protein extracts were obtained from climacteric fruits (pear, tomato) and nonclimacteric fruits (blueberry) during various stages of ripening. The use of a gel electrophoresis technique revealed a consistent reinforcement in indoleacetic acid oxidase but not in peroxidase isozymes during ripening. The significance of the results is discussed in relation to t
