Latim e formação lingüística

Sob a perspectiva de que o latim é a língua viva (do passado) e após reflexões decaráter lingüístico que orientam o trabalho, procura-se apresentar, como exemplo, uma unidadede programa de ensino lingüístico do latim, sem incidir em anacronismos e equívocos do velhopensamento humanístico.

O acaso, o poeta e a re-visão da ciência no límen do milênio

O Canto II do poema A Máquina do Mundo Repensada, de Haroldo de Campos (2000), é inovador ao trazer, para o cerne de um texto composto em terza rima, a ciência como protagonista da mensagem poética veiculada ao longo dos versos. Se na primeira parte do poema há um retorno aos textos da tradição, na segunda, ainda que esses diálogos permaneçam sub-repticiamente, o impulso para novos horizontes é assegurado pelo ingresso do tema científico no poema, que impulsiona o eu-poético a novos caminhos e estreita as possibilidades de estabelecimento do texto literário como palco das descobertas da ciência, ao mesmo tempo que questionador dessas descobertas. No Canto II do poema haroldiano, objeto de análise neste artigo, o desbravar das fronteiras da literatura tangencia o desbravar das fronteiras da ciência. Isso faz de Haroldo um poeta do “absolutamente novo”.

Does hyperglycemia in pregnancy change fetal kidney growth?: a longitudinal prospective study

PURPOSE: To measure fetal renal volume in normoglycemic and hyperglycemic pregnancies. METHODS: A longitudinal prospective study was conducted and included 92 hyperglycemic and 339 normoglycemic pregnant women attended at the prenatal service of a hospital from Rio de Janeiro State. Ultrasound examinations were performed to estimate gestational age at baseline and the kidney volume was estimated using the prolate ellipsoid volume equation. RESULTS: Fetal kidney volume growth between normoglycemic and hyperglycemic pregnancies are significantly different. The fetal kidney volume growth in pregnancy is positively correlated with gestational age explained by these predictor equations, by group: normal renal volume = exp (6.186+0.09×gestational week); hyperglycemic renal volume = exp (6.978+0.071×gestational week) and an excessive growth pattern for hyperglycemic pregnancies may be established according to gestational age. CONCLUSION: This is important for early detection of abnormalities in pregnancy, particularly in diabetic mothers.

Avaliação de fungicidas, óleos essenciais e agentes biológicos no controle de Amphobotrys ricini em mamoneira (Ricinus communis L.)

The castor bean (Ricinus communis L.) is a tropical oilseed species, and the oil extracted from its seeds is one of the most versatile oils in the nature, showing various industrial uses. Even though it is a rustic species, the castor bean is subjected to several diseases such as the gray mold, caused by the fungus Amphobotrys ricini. Genetic breeding would be the best alternative for the disease control, but a long time is required to obtain resistant cultivars. Thus, the use of control strategies based on chemical, alternative or biological methods shows viable in the short term. The aim of this study was to investigate gray mold control efficiency, in castor bean crop, using chemical, alternative and biological methods. The pathogen control efficiency was evaluated both in vitro and in vivo using fungicides, essential oils and biological control agents. As regards the in vitro inhibition of the pathogen mycelial growth, the best treatments with essential oils were those based on C. martini and C. zeylanicum at all five tested concentrations. For both oils, the average diameter of colonies was 0.7 cm against 4.79 cm for the control treatment. For the fungicides, at all four tested levels, the most efficient active ingredients were methyl tiophanate, carbendazim, tebuconazole and iprodione. The ED50 of these fungicides was <1uL/L, yielding 100% mycelial growth inhibition at all concentrations. As to the inhibition of A. ricini conidium germination, the fungicides tebuconazole and chlorotanolyl were the best at all tested concentrations, and the average of germinated conidia with these fungicides was 0.0 and 0.15%, respectively, against 100% for the control treatment. In the field, treatment with the fungicide iprodione was the best for the disease control when compared to biological and alternative treatments. Under field conditions, the average disease severity for the treatment with iprodione was 15.76% against 95.81% for the inoculated control.

Características químicas, físicas e sensoriais de bolos de laranja e pães adicionados de inulina e oligofrutose

Inulin and oligofructose are fructans that can change important characteristics in original products when added in food. Two formulations of orange cakes (one containing 77.7g of inulin and another one 77.7g of oligofructose/inulin) and two formulations of breads (one containing 130g of inulin and another one 175g of oligofructose/inulin) were compared to the respective standard formulations (with no fructans) in relation to chemical composition, texture, volume, color and sensory acceptability with a nine-point hedonic scale. The cakes and breads with inulin and oligofructose/inulin showed greater amount of total dietary fiber in relation to standard products. The orange cake with inulin had lower cohesiveness and yellower dough when compared to the standard cake, but the addition of inulin and oligofructose/inulin reduced the acceptability for appearance, texture and flavor and the overall acceptability, although the acceptability for aroma was the same for the three products. The breads with inulin and oligofructose/inulin were harder and less cohesive than the standard bread, and bread with inulin showed minor volume in relation to the standard. The bread with inulin also presented crust with lower luminosity, dough with higher intensity of redness and yellowness and higher intensity of color in relation to standard, besides different hue. In relation to sensory acceptability, the bread with oligofructose/inulin had higher overall acceptability and flavor when compared to standard bread.

Polymorphisms in Osteopontin Gene in Amazon Buffaloes

The aim of this work was to identify polymorphisms in the osteopontin gene. It was used in this experiment 306 male buffaloes, older than 18 months, bred in two farms, one in the State of Amapa and the other farm in the State of Para. There was identified three SNP polymorphisms for the region amplified by the primer OS4 (5'upstream) and four SNP polymorphisms for the region amplified by the primer OS9 (exon 5 to exon 6). The polymorphisms were in positions 1478, 1513 and 1611 in the region amplified by OS4 and positions 6690, 6737, 6925 and 6952 in the region amplified by OS9. These data indicate that the osteopontin gene is important because it can have a substantial influence on the reproductive traits of male buffaloes.
