This study aimed to investigate the potential use of magnetic susceptibility (MS) as pedotransfer function to predict soil attributes under two sugarcane harvesting management systems. For each area of 1 ha (one with green sugarcane mechanized harvesting and other one with burnt sugarcane manual harvesting), 126 soil samples were collected and subjected to laboratory analysis to determine soil physical, chemical and mineralogical attributes and for measuring of MS. Data were submitted to descriptive statistics by calculating the mean and coefficient of variation. In order to compare the means in the different harvesting management systems it was carried out the Tukey test at a significance level of 5%. In order to investigate the correlation of the MS with other soil properties it was made the correlation test and aiming to assess how the MS contributes to the prediction of soil complex attributes it was made the multiple linear regressions. The results demonstrate that MS showed, in both sugarcane harvesting management systems, statistical correlation with chemical, physical and mineralogical soil attributes and it also showed potential to be used as pedotransfer function to predict attributes of the studied oxisol.

The study of the nervous system is increasing in Veterinary Medicine. Transcranial ultrasonography (TCUS) has the advantage of being a non-invasive and low cost method compared to computerized tomography (CT) and Magnetic Resonance Imaging (MRI). The temporal bone has been used as an acoustic window in TCUS in humans. This study aimed to correlate transcranial ultrasonographic images obtained through the temporal and occipital window with healthy dog's encephalic anatomy, and to standardize the technique. 37 adult mongrel dogs were used: 30 animals in vivo, in order to perform USTC screening and seven dog corpses for brain section as well as USTC planes. Data analysis was accomplished by the non parametric Wilcoxon test. Results obtained indicate that TCUS (in dorsal and oblique planes) is a viable method for brain evaluation in dogs weighting up to 10kg without anesthesia.

A fração em acetato de etila (EtOAc) obtida a partir da partição do extrato de etanol (EtOH) das folhas de O. sessiliflora R. E. Fries (Annonaceae) foi submetida a diversos procedimentos cromatográficos, incluindo cromatografia líquida de alta eficiência (HPLC), o que resultou no isolamento dos flavonóides: quercetina-3-O-α-L-ramnopiranosil-(1→4)-β-D-glucopiranosídeo (1), inédito na literatura, canferol-3-O-α-L-ramnopiranosil-(1→4)-β-D-glucopiranosídeo (2), rutina (3) e canferol-3-O-rutinosídeo (4). As estruturas foram definidas através da análise dos espectros de ressonância magnética nuclear (NMR) de ¹H e de 13C (1D e 2D) e espectrometria de massas.
