Abstract: Introduction: Severe Epistaxis is common in patients with head trauma, especially when associated with multiple fractures of the face and skull base. Several methods of controlling bleeding that can be imposed. The anterior nasal tapenade associated with posterior Foley catheter is one of the most widespread, and the universal availability of necessary materials or their apparent ease of execution. Methods: Case report on control of severe epistaxis after severe TBI, with posterior nasal packing by Foley catheter and control tomography showing multiple fractures of the skull base and penetration of the probe into the brain parenchyma. Conclusion: This is a rare but possible complication in the treatment of severe nose bleeds associated with fracture of the skull base. This brief report highlights risks related to the method and suggests some care to prevent complications related through a brief literature review.

Abstract: Fruit rot, besides causing losses in production, reduces the final quality of the product interfering in the commercialization. The objective of this work was to evaluate the efficiency of alternative products applied to pre-harvest for control of brown rot (Monilinia fructicola) and soft rot (Rhizopus spp.) In peaches. The experiment was conducted in the municipality of Nepomuceno-MG, in a peach orchard of the cultivar Diamante. The experimental design was a randomized block design with 7 treatments and 3 replicates, with field plots formed by 12 plants (arranged in 3 rows), being considered for the evaluations only the two central plants. Three applications were made at flowering and at 21; 7 and 3 days before harvest, with solutions containing the following treatments: 1-Clove oil 0.1%; 2-silicate clay 1.5%; 3-Phosphite K 0.20%; 4-Benzalkonium chloride 0.25%; 5-Azoxystrobin 0.02%; 6-Iprodione 0.15%; 7-Witness (water only). Treatments 4 and 5 were applied only at 21 and 7 days before harvest. Ten fruits were selected and placed in sterile trays under uncontrolled conditions, with disease evaluations at 3 and 6 days after the beginning of storage in 2005 and at 3; 6 and 9 days in 2006. The iprodione controlled the incidence of M. fructicola and had no effect on Rhizopus spp. Clove oil controlled the incidence and severity of M. fructicola by the fifth day and Rhizopus spp. by the sixth day. The phosphites of k, benzalkonium chloride and azoxystrobin were efficient in controlling the incidence and severity of Rhizopus spp. and had no effect on M. fructicola.

RSBO , 2010,
Abstract: Introduction: Root canal system obturation uses filling materials and sealers that should present, among other proprieties, a biocompatibility to the periradicular tissues. Objective: To compare, in vivo, bone tissue response to two types of biomaterials: Resilon points and gutta-percha points. Material and methods: For this purpose, 40 male albino Wistar rats were used for implantation of the biomaterial points in their previously perforated left tibia. Twenty rats received gutta-percha point implants and the other 20 rats received Resilon point implants. All animals had their right tibia partially perforated, as a control group. At the end of the 2nd, 4th, 8th and 16th week post-implantation, bone tissue samples were taken for analysis. Histological sections were stained by HE, photographed, and morphologically analyzed using TPS Dig 1.38 software. Tissue response was analyzed, taking into consideration the periosteum thickness variation in the formed bone callus area. Results: Data were statistically analyzed by ANOVA, followed by Tukey’s test (p < 0.05). There was no statistical difference between the materials tested, when the periosteum thickness was analyzed. Conclusion: Both Gutta-percha and Resilon points were biocompatible and well tolerated when implanted in bone tissue of rats.

Abstract: The effect of cover crops annually implanted in the summer, since 2001, under no-tillage system, on the soil chemical attributes was evaluated. The experiment was carried out in Embrapa Rice & Beans, in Santo Ant nio de Goiás, GO, Brazil, in a Dystrophic Red Latosol (Red Oxisol). Brachiaria brizantha, corn (Zea mays L.) associated with B. brizantha, pigeon pea, millet, Panicum maximum, sorghum, Stylosanthes guianensis, and sunn hemp were used as cover crops. Sixty days after the cut of the cover crops, common bean crop was implanted, under a central pivot sprinkler irrigation system. In November 2001, 2005, and 2006, soil samples were collected in the depths of 0-5 cm, 5-10 cm, and 10-20 cm. Immediately after the 2005 sampling, it was applied 4,000 kg ha-1 of dolomitic lime, in all the experimental area. Cover crops affected soil pH and magnesium content in the superficial layer. Soil under millet showed higher phosphorus content in subsuperficial layers, in relation to the initial values. The soil P and Cu contents were higher in the subsuperficial layers, while the other chemical attributes were higher in the superficial layer. There was movement of Ca and Mg in the soil profile, one year after the application of lime in the soil surface. KEY-WORDS: No-tillage system; grasses; Leguminosae; soil fertility. Avaliaram-se os efeitos de culturas de cobertura implantadas anualmente no ver o, desde 2001, em sistema plantio direto, sobre os atributos químicos do solo.

Abstract: Este trabalho foi desenvolvido com objetivo de se avaliar três formas de manejar a irriga o do feijoeiro. A cultivar de feij o preto BRS Supremo foi submetida ao manejo da irriga o por tensiometria, tanque Classe A e Penman-Monteith. Avaliaram-se a produtividade de gr os, número de vagens por planta, número de gr os por vagem, massa de 100 gr os, altura da planta, lamina total e eficiência de uso da água. O método do tanque propiciou a maior lamina acumulada e a maior frequência de irriga o. A lamina total estimada por tensiometria foi 29,7 e 17,8% menor que a estimada pelos métodos do tanque e de Penman-Monteith, respectivamente. Houve diferen as significativas quanto à produtividade de gr os, número de gr os por vagem e altura da planta. O método do tanque propiciou a obten o de maiores produtividades enquanto o método da tensiometria levou à economia de água de irriga o ocorrendo, no entanto, redu o da produtividade. Plantas de feijoeiro submetidas a déficit hídrico de 21 e 37%, respectivamente, nas fases vegetativa e reprodutiva tiveram sua produtividade reduzida em 29%. Déficit hídrico de 22% na fase reprodutiva reduziu a produtividade do feijoeiro em 15%. N o foram observadas diferen as significativas na eficiência do uso da água. The objective of this research was to evaluate three methods of irrigation management in the bean crop. The variety of black bean BRS Supremo was submitted to irrigation management by tensiometry, Class A pan method, and Penman-Monteith. The productivity of grains, number of grains per plant, grains per berry, weight of 100 grains, height of plants, total water depth and water use efficiency were evaluated. The method of the Class A pan promoted the largest accumulated water depth and the largest irrigation frequency. The tensiometry underestimated in 29.7 and 17.8% the total water depth estimated by the Class A pan method, and Penman-Monteith, respectively. The results demonstrated that there were significant differences for the productivity of grains, number of grains per berry and height of plants. The Class A pan method favored larger productivities, while the tensiometry took the economy of irrigation water, having, however, reduction of the productivity. Bean plants subjected to water deficit of 21 and 37%, respectively, in the vegetative and reproductive stages, have their productivity reduced by 29%. Water deficit of 22% in the reproductive stage reduces the productivity by 15%. There were no significant differences in the water use efficiency.
