La disponibilidad de información cuantitativa sobre inversiones en infraestructura es imprescindible para realizar análisis e investigaciones sobre el tema y para que quienes adoptan decisiones de política puedan formular medidas pertinentes, oportunas y sostenibles. La existencia de una base de datos robusta y estandarizada podría facilitar respuestas para varias preguntas cruciales: ¿cuánto debe crecer la inversión en infraestructura para que el PIB crezca, por ejemplo, en un punto porcentual?, ¿cuál es el nivel de la inversión en infraestructura que maximiza el crecimiento?, ¿es sostenible en el largo plazo?, ¿se gasta lo suficiente en mantenimiento o reparaciones?, ¿en cuánto tiempo se espera que una determinada obra de infraestructura tenga el esperado impacto económico y social?, ¿el monto de inversión que se efectúa en infraestructura compensa el agotamiento de otro tipo de capitales?, ¿es apropiada para el desarrollo sostenible la estructura sectorial de la inversión en infraestructura?, en fin, ¿qué porcentaje de las inversiones en infraestructura se originan en rentas y otros beneficios de la extracción de recursos naturales?, entre otros.

Sildenafil attenuates acute pulmonary embolism-induced pulmonary hypertension. However, the hemodynamic effects of sildenafil in combination with other vasodilators during acute pulmonary embolism have not been examined yet. In the present study, we examined the hemodynamic effects of combined sildenafil (0.25 mg/kg, i.v.) and L-arginine (100, 200, 500, and 1000 mg/kg/h, i.v.) in an anesthetized dog model of acute pulmonary embolism. Plasma nitrite/nitrate (NOx) and cGMP concentrations were determined using an ozone-based chemiluminescence assay and a commercial enzyme immunoassay, respectively. We found that L-arginine alone did not attenuate acute pulmonary embolism-induced pulmonary hypertension. However, significant decreases in mean pulmonary artery pressure were observed 30, 45, 60, and 75 min after the administration of sildenafil alone or after the combined administration of sildenafil and L-arginine (all P<0.05). No significant differences among groups were observed in the respiratory parameters. While L-arginine significantly increased NOx concentrations, cGMP concentrations increased only when sildenafil was administered (all P<0.05). These results suggest that while sildenafil attenuates acute pulmonary embolism-induced pulmonary hypertension, L-arginine does not enhance the beneficial hemodynamic effects of sildenafil. In addition, these findings suggest that stimulation of NO synthesis with L-arginine during acute pulmonary embolism does not produce beneficial effects. (c) 2005 Elsevier B.V. All rights reserved.

Supernumerary teeth are a relatively frequent disorder of odontogenesis that can interfere with the development of the germs teeth. This pathology is most common in the maxillary anterior area, called mesiodens, and their prevalence is generally reported to occur more frequently in male than female, in a ratio of 2:1. The aim of this article was to report the clinical procedures performed in the Clinic of Pediatric Dentistry at the Araraquara School of Dentistry when the presence of two mesiodens, radiographically shown, caused retention of permanent anterior teeth, resulting in esthetic and funcional disturb. All the surgical procedures, etiology and the importancy of the early diagnostic for the appropriate treatment was detailed described.
