Aspectos epidemiológicos da saúde bucal de crianças em um município brasileiro

The Health Sciences, prior to the planning of prevention programs, adopt the tools to analyze the population profile, entitled epidemiological surveys, to obtain data on the need for heathcare and the possibility of treating health events. The aim of this study was to evaluate dental conditions in schoolchildren, aged five to fourteen, enrolled in public schools in Américo Brasiliense, SP Brazil. The dmft and DMFT index, caries experience, and prevalence of fluorosis were analyzed. For this epidemiological study, 1,137 children were selected. Four calibrated dentists performed oral exams according to WHO criteria (1997). The data were collected using descriptive analyses. The results showed that 94% of the five-year-old children were caries free, and the value of dmft was 1.44. DMFT was 1.19 in 12-year-olds. The lowest and the highest fluorosis prevalence could be observed in eight and fourteen-year-olds, respectively. It could be concluded that the city of Américo Brasiliense has developed respectful educational and preventive oral health programs which presented satiosfactory results in the present epidemiological study.

Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry for Differentiation of the Dimorphic Fungal Species Paracoccidioides brasiliensis and Paracoccidioides lutzii

Isolates of Paracoccidioides brasiliensis and Paracoccidioides lutzii, previously characterized by molecular techniques, were identified for the first time by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). All isolates were correctly identified, with log score values of >2.0. Thus, MALDI-TOF MS is a new tool for differentiating species of the genus Paracoccidioides.

Carbohydrates, growth and production of -roxo de valinhos- fig tree in initial development under irrigation management

The carbohydrates translocation and consequently growth and production of fig tree (Ficuscarica L.) vary according to the different management on cultivation conditions. The aim of this study was to evaluate the changes in the levels and total carbohydrates accumulation together with growth and “Roxo de Valinhos” fig trees production onimplementation of orchards in initial phase, cultivated with and without irrigation. We adopted a factorial arrangement (2 x 7) with four repetitions distributed in installments (with and without irrigation) subdivided in time (collect time). Destructive analyzes were performed at 40, 80, 120, 160, 200, 240 and 280 days after pruning (DAP) and are measured: stem diameter and branch, stem length and branch, number of leaves, internodes and fruit. Subsequently, the plant parts were sectioned to obtain the leaf area, length and roots volume, fresh and dry matter weight. The number, weight and total productivity of fruits were evaluated. The media of all growth attributes and production characteristics were higher in treatments with water irrigation. The total carbohydrate content was higher at 120 and 160 DAP and the carbohydrates accumulation was increasing for most institutions over the plants development, except for the leaves that showed a decrease in the levels at 160 DAP. The fruits showed greater carbohydrates accumulation in relation to the other evaluated organs.
