RESUMO

Genetic information in genomes is ordered, arranged in such a way that it constitutes a code, the so-called cis regulatory code. The regulatory machinery of the cell, termed trans-factors, decodes and expresses this information. In this way, genomes maintain a potential repertoire of genetic programs, parts of which are executed depending on the presence of active regulators in each condition. These genetic programs, executed by the regulatory machinery, have functional units in the genome delimited by punctuation-like marks. In genetic terms, these informational phrases correspond to transcription units, which are the minimal genetic information expressed consistently from initiation to termination marks. Between the start and final punctuation marks, additional marks are present that are read by the transcriptional and translational machineries. In this work, we look at all the experimentally described and predicted genetic elements in the bacterium Escherichia coli K-12 MG1655 and define a comprehensive architectural organization of transcription units to reveal the natural genome-design and to guide the construction of synthetic genetic programs.

RESUMO

En este trabajo se evaluó el efecto del consumo del jugo de tomate de árbol (Cyphomandra betacea) sobre parámetros nutricionales y bioquímicos en 54 voluntarios (44 mujeres y 10 hombres) con edades 45±8 años de Ecuador. Al inicio se les realizó una evaluación nutricional y bioquímica, luego se les invitó a consumir el jugo (100g de fruto en 150 ml de agua) diariamente durante 6 semanas. Finalizado este tiempo, se procedió a realizar la evaluación nutricional y bioquímica nuevamente. La evaluación nutricional determinó 67% de obesidad abdominal. Disminuyendo a 53% después del consumo del jugo de tomate de árbol. El 87% de los voluntarios antes del tratamiento, mostraron hipercolesterolemia; 40,7% y 46,3% tenían los triglicéridos y el LDL elevados y 18,5% valores de glucosa entre 98-130mg/dL. Valores que disminuyeron significativamente en este grupo después de la toma del jugo En general, tanto en voluntarios con y sin sobrepeso se observó disminución significativa de colesterol total, LDL y glucosa; sin cambios significativos en los valores de HDL. El consumo del jugo no afectó la actividad de las enzimas alanina-aminotransferasa ni aspartato-aminotransferasa, tampoco las concentraciones de creatinina, urea y ácido úrico; ni la presión arterial, demostrando que no afecta la función hepática ni renal. Estos resultados indican que el consumo del jugo de tomate de árbol, durante seis semanas, parece ejercer un efecto hipolipemiante y moduladora en el metabolismo de la glucosa y colocan a C betacea como uno de los frutos andinos con alto potencial nutraceutico. Sin embargo, estos aspectos deben ser investigados con más detalles(AU)


In this work the effect of consumption of tree tomato juice (Cyphomandra betacea) was evaluated on nutritional and biochemical parameters in 54 volunteers (44 women and 10 men) aged 45 ± 8 years-Ecuador. A nutritional and biochemical evaluation was performed in volunteers; then they were invited to drink tree tomato juice (100g of fruit in 150 ml of water) daily for 6 weeks. Finished these 6 weeks, volunteers were nutritional and biochemical evaluated again. 67% abdominal obesity was found, decreasing at 53% after drinking the established dosage of juice. 87% of the volunteers before treatment, showed hypercholesterolemia, 40.7% and 46.3% had hypertriglyceridemia and elevated LDL, respectively and 18.5% glucose concentrations between 98-130 mg/dL. These values decrease significantly in this group after drinking tomato juice. In general, Total Cholesterol, LDL and glucose concentrations decrease significantly after drinking tree tomato juice in all the voluntaries with or without overweight. There is no change in HDL concentrations. The consumption of tree tomato juice did not affect the activity of alanine aminotransferase or aspartate aminotransferase enzymes either creatinine, urea and uric acid concentrations, neither blood pressure suggesting that does not affect renal or liver function. These results indicate that consumption of tree tomato juice for six weeks appears to have a lipid-lowering and modulating effect on glucose metabolism, suggesting C betacea as one of the high Andean fruits nutraceutical potential. However, this issue should be investigated in more detail(AU)

RESUMO

En la muestra estudiada (sitios con profundidad de sondaje mayor a 4mm. en pacientes con Periodontitis del Adulto moderada o grave) la administración de Espiramicina sistémica produjo los siguientes efectos: CLINICOS: 1. La Espiramicina adjunta al raspaje y alisado radicular produjo mayor reducción de la profundad de sondaje a las 5 días que el tratamiento mecánico sólo. 1. Produjo mejoría de los indicadores clínicos de la Enfermedad periodontal, logrando sobre la profundidad de sondaje y el nivel Clínico de inserción un efecto significativamente diferente de aquel producido por el otro grupo. 3. Logro reducir en mayor grado el sangrado al sondaje y la inflamación gingival
