Resumo Objetivo: Avaliar e reconstruir imagens tridimensionais da vascularização ao longo da trompa de Falópio (TF) e sua relação com o ovário e fímbria do ovário, além de quantificar os vasos sanguíneos ao longo da TF de acordo com seus segmentos anatômicos usando microtomografia confocal (micro-TC). Materiais e Métodos: Nove espécimes (seis com TFs e três com TFs e ovários) foram fixados em solução de formol a 10% por mais de 24 h à temperatura ambiente. A coloração com iodo foi realizada usando solução de Lugol a 10% durante 24 h. Todos os espécimes foram avaliados usando micro-TC. Uma análise morfométrica foi realizada nas imagens reconstruídas para quantificar a distribuição vascular ao longo da TF. Resultados: A densidade dos vasos sanguíneos nas fímbrias foi significativamente aumentada em comparação ao segmento ístmico da TF (p < 0,05). A fímbria ovariana foi claramente identificada, demonstrando importante relação entre esses vasos e as fímbrias da TF. Conclusão: Acreditamos que as fímbrias apresentam vascularização aumentada e desproporcional em comparação com os demais segmentos da TF e que a fímbria ovariana desempenha importante papel nessa diferença.

Abstract Objective: To evaluate and reconstruct three-dimensional images of vascularization along the fallopian tube (FT), as well as to determine its relationship with the ovary and ovarian fimbria, and to quantify the blood vessels along the FT according to its anatomical segments, using confocal microtomography (micro-CT). Materials and Methods: Nine specimens (six FTs and three FTs with ovaries) were fixed in a solution of 10% formalin for > 24 h at room temperature. Iodine staining was performed by soaking the specimens in 10% Lugol’s solution for 24 h. All specimens were evaluated using micro-CT. A morphometric analysis was performed on the reconstructed images to quantify the vascular distribution along the FT. Results: In the FTs evaluated, the density of blood vessels was significantly greater in the fimbrial segments than in the isthmic segments (p < 0.05). The ovarian fimbria was clearly identified, demonstrating the important relationship between these vessels and the FT fimbriae. Conclusion: We believe that the vascularization in the fimbriae is greater than and disproportional that in the other segments of FT, and that the ovarian fimbria plays an important role in the development of that difference.

ABSTRACT Considering the importance of topographic surveys to determine soil volumes and study efficient and accessible alternatives for this operation, this study aimed to analyze methods and respective equipment for planialtimetric surveys to determine soil volume. An experimental grid was installed in an area locate in Fernandópolis, SP, Brazil, in which quotas were measured by geometric leveling (standard method), trigonometric leveling, leveling with receivers of the Global Navigation Satellite System (GNSS) by relative (frequencies L1/L2) and absolute positioning (code C/A) and extraction of altitudes in digital terrain model from SRTM and ASTER images. In comparison to geometric leveling, trigonometric leveling was the most accurate in determining soil volume (0.6% error), followed by GNSS leveling by relative positioning (23.7% error), and extraction of altitudes by SRTM (32.0% error) and ASTER images (38.3% error). GNSS leveling by absolute positioning presented the highest error in determining soil volume (287.4%) compared to the other methods.

In human identification for forensic purposes the sex is one of the most important and first features to be assessed in each case. Baudoin condylar index is a sex determination method based on measurements of length and width of the occipital condyle. The aim of this research was to apply the Baudoin condylar index for sex determination, and evaluate its reliability. The sample was composed of 100 Brazilian human skulls, 50 male and 50 female from São Gonçalo cemetery, City of Cuiabá, Brazil. The measurement values were statistically analyzed in order to compare the matching rate for each sex, each side, as well as the overall average. The results showed that the overall percentage of success in applying the Baudoin index was 44.83% to males, and 51.93% to females, amounting to 47.5% matching. The accuracy of the Baudoin index to sex determination was quite low for this Brazilian sample, the reason why this method should be disregarded as a criterion to sexing skulls in a forensic context.

En la identificación de personas con fines forenses el sexo es una de las características más importantes y primordiales a evaluar en cada caso. El índice condilar Baudoin es un método de determinación del sexo basado en mediciones de la longitud y la anchura del cóndilo occipital. El objetivo de esta investigación fue aplicar el índice condilar de Baudoin para la determinación del sexo, y evaluar su fiabilidad. La muestra fue compuesta de 100 cráneos humanos brasileños, 50 hombres y 50 mujeres del cementerio São Gonçalo, ciudad de Cuiabá, Brasil. Los valores de medición se analizaron estadísticamente con el fin de comparar la tasa de coincidencia para cada sexo, cada lado, además de la media general. Los resultados mostraron que el porcentaje general de éxito en la aplicación del índice de Baudoin fue de 44,83% para los hombres y 51,93% para las mujeres, lo que asciende a una coincidencia del 47,5%. La precisión del índice de Baudoin para la determinación del sexo fue bastante baja para esta muestra brasileña, por lo que este método debe ser considerado como criterio para determinar el sexo de los cráneos en un contexto forense.
