ABSTRACT
RESUMO: Objetivou-se com este trabalho avaliar a produção de massa e o teor de flavonoides de plantas de marcela cultivadas com fósforo e cama de frango e colhidas em duas épocas. Estudou-se a combinação de doses de P2O5 (0, 100, 200 e 300 kg ha-1) na forma de superfosfato triplo, com e sem cama de frango (10 t ha-1), arranjados como fatorial 4x2, no delineamento blocos casualizados, com quatro repetições. Foram feitas duas colheitas das plantas, consideradas como parcelas subdivididas no tempo. A propagação foi indireta, com semeio em bandejas e transplante ao campo. As plantas foram colhidas aos 195 e 223 dias após o transplantio - DAT. A altura máxima das plantas foi de 1,14 m com uso da cama de frango e de 0,97 m sem cama, aos 195 dias após o transplantio. A produção máxima de massa fresca de parte aérea das plantas foi de 30,31 t ha-1 na colheita aos 223 DAT, enquanto a de massa seca foi de 11,38 t ha-1, ambas com o uso de 300 kg ha-1 de P2O5.A massa fresca de inflorescências foi maior (4,08 t ha-1) com adição de cama de frango ao solo e menor (3,49 t ha-1) sem cama de frango; em resposta às doses de fósforo, cresceram linearmente, sendo a máxima de 4,65 t ha-1 com uso de 300 kg ha-1 de P2O5, independente da época de colheita. A massa seca de inflorescências foi máxima de 2,38 t ha-1 com o uso de 300 kg ha-1 P2O5 na colheita aos 223 DAT. A maior produção de massa seca e o maior teor de flavonoides das inflorescências foram obtidos com o cultivo das plantas de marcela em solo com cama de frango (10 t ha-1) e com P2O5 (300 kg ha-1) na colheita aos 223 dias após o transplantio.
ABSTRACT: The aim of this experiment was to evaluate the biomass yield and flavonoid contents of Achyrocline satureioides grown under different levels of phosphate fertilizer in association with broiler litter, during two successive harvests. Four levels of P2O5 (0, 100, 200 and 300 kg ha-1), as triple superphosphate, and two levels of broiler litter (0 and 10 t ha-1) were arranged as a 4x2 factorial design in randomized blocks with four replications. Two harvests of plants, considered as split-plot, were made. Seeds were sown in polystyrene trays then transplanted to the experimental field and harvested at 195 and 223 days after transplanting (DAT). The maximum heights of the plants were 1.14 m under the addition of broiler litter and 0.97 m without it, at 195 days after transplanting. The highest yields of total fresh weight (30.31 ton ha-1) and dry weight (11.38 ton ha-1) were obtained at 223 DAT, both with the concentration of 300 kg ha-1 P2O5. The fresh weight of the inflorescences was greater under the addition of broiler litter (4.08 ton ha-1) than without it (3.49 ton ha-1). The plants grew linearly in response to the use of phosphate, and the maximum yield was 4.65 ton ha-1 under the concentration of 300 kg ha-1 P2O5, regardless of the harvest season. The dry weight of the inflorescences reached maximum yield (2.38 ton ha-1) at 223 DAT, in response to the use of 300 kg ha-1 P2O5. The highest yield of dry weight and the highest contents of flavonoids from the inflorescences were obtained when A. satureioides was grown under the concentration of P2O5 (300 kg ha-1) with the addition of broiler litter (10 ton ha-1) and harvested at 223 DAT.

RESUMO: O objetivo do trabalho foi avaliar a influência de diferentes composições de substratos no crescimento inicial de Campomanesia xanthocarpa, bem como avaliar índices fisiológicos. O trabalho foi desenvolvido em Dourados-MS, no período de janeiro a outubro de 2008. Foi estudada a Campomanesia xanthocarpa sob cinco diferentes substratos (LVd/A/O= Latossolo Vermelho distroférrico+areia grossa lavada+Organosuper® (5:4:1 v/v); LVd/A/C= Latossolo Vermelho distroférrico+areia grossa lavada+cama-de-frango (5:4:1 v/v); LVd/A/O2= Latossolo Vermelho distroférrico+areia grossa lavada+Organosuper® (7:2:1 v/v); LVd/A/C2= Latossolo Vermelho distroférrico+areia grossa lavada+cama-de-frango (7:2:1 v/v); LVd/A= Latossolo Vermelho distroférrico+areia grossa lavada (6:4 v/v)), em vasos de 7 dm3, e mantidos em ambiente protegido com 100% de luminosidade. O substrato composto por Latossolo Vermelho distroférrico + areia grossa lavada proporcionou maior diâmetro de caule (8,29 mm), massa seca de raiz, caule e folhas (6,98; 4,49 e 9,06 g/planta, respectivamente) e aumento nos índices fisiológicos nas avaliações finais, indicando que este substrato pode ser utilizado no desenvolvimento de Campomanesia xanthocarpa.
ABSTRACT: The objective of this study was to evaluate the influence of different compositions of substrates on the initial growth of Campomanesia xanthocarpa and to evaluate the physiological rate. The study was conduct in the city of Dourados - state of Mato Grosso do Sul, Brazil, in the period from January to October 2008. The Campomanesia xanthocarpa was studying under five different substrates (LVd/A/O= Oxisol+coarse sand+Organosuper® (5:4:1 v/v); LVd/A/C= Oxisol+ coarse sand+ chicken manure (5:4:1 v/v); LVd/A/O2= Oxisol+ coarse sand+Organosuper® (7:2:1 v/v); LVd/A/C2= Oxisol+ coarse sand+chicken manure (7:2:1 v/v); LVd/A= Oxisol+ coarse sand (6:4 v/v)) in 7 dm3 pots and kept in a protected environment with 100% brightness. The substrate consisting of Oxisol + coarse sand provided greater stem diameter (8.29 mm), dry weight of the root, stem and leaf (6.98, 4.49 and 9.06 g / plant, respectively) and increased the physiological indices in the final evaluations, which indicates that this substrate can be used in the development of Campomanesia xanthocarpa.

Objetivo Determinar los tiempos de asistencia, características extrahospitalarias e intrahospitalarias y supervivencia de las paradas cardiacas atendidas por una UVI móvil, al igual que los factores implicados en la supervivencia al ingreso y al alta hospitalaria. Diseño Estudio observacional retrospectivo desde el 1 de enero de 2010 al 31 de diciembre de 2010, con un seguimiento de un año desde la PCR. Ámbito Área sanitaria IV del Principado de Asturias, con 342.020 habitantes en 2010.PacientesSe incluyeron todos los pacientes que sufrieron una PCR en 2010 y fueron atendidos por la UVI móvil. Variables principales Datos demográficos, causa de la PCR, intervención por testigos, tiempos de asistencia y supervivencia al ingreso, al alta y un año después. Resultados Se atendieron un total de 177 paradas cardiacas. En 120 se indicó el soporte vital avanzado (SVA), siendo 66 de ellas (55%) de causa presumiblemente cardiaca. Recuperaron el pulso 63 pacientes (52,5%), llegando 51 de ellos con vida al hospital (42,5%). Se les dio el alta a 13 pacientes (10,8%). Al año 11 (9,2%) seguían vivos y 9 de ellos (7,5%) tenían una cerebral performance category (CPC) de 1. El ritmo inicial de fibrilación ventricular (FV) y los tiempos cortos en la asistencia se relacionaron con la supervivencia. Conclusiones La supervivencia fue superior a la publicada al ingreso al hospital y similar a la del alta. Como factores relacionados se encontraron los tiempos de asistencia y el ritmo inicial. La reanimación por el testigo fue escasa y no se usaron desfibriladores semiautomáticos (DEA) públicos (AU)
Objective To evaluate attendance timings, out- and in-hospital characteristics, and survival of cardiac arrests attended by an advanced life support unit in Asturias (Spain) in 2010. Factors related to survival upon admission and at discharge were also analyzed. Design A retrospective, observational trial was carried out involving a cohort of out-hospital cardiac arrests (OHCA) occurring between 1 January 2010 and 31 December 2010, with one year of follow-up from OHCA. Setting Health Care Area IV of the Principality of Asturias, with a population of 342,020 in 2010.PatientsAll patients with OHCA and attended by an advanced life support unit were considered. Main variables Demographic data, the etiology of cardiac arrest, bystander cardiopulmonary resuscitation (CPR), attendance timings and survival upon admission, at discharge and after one year. Results A total of 177 OHCA were included. Of these, 120 underwent CPR by the advanced life support team. Sixty-six of these cases (55%) were caused by presumed heart disease. A total of 63 patients (52.5%) recovered spontaneous circulation, and 51 (42.5%) maintained circulation upon admission to hospital. Thirteen patients (10.8%) were discharged alive. After one year, 11 patients were still alive (9.2%) - 9 of them (7.5%) with a Cerebral Performance Category (CPC) score of 1. Ventricular fibrillation and short attendance timings were related to increased survival. Conclusions The survival rate upon admission was better than in other series and similar at discharge. Initial rhythm and attendance timings were related. Public automated external defibrillators (AED) were not used, and bystander CPR was infrequent (AU)

AIM: To assess the dentine/fibreglass-bonded interface by scanning electron microscopy and the push-out bond strength of four luting cements. METHODOLOGY: Forty root-filled human canines, with similar root lengths, were restored with fibreglass posts and randomly divided into four groups according to the cements employed (CG Gold Label I, RelyX ARC, BisCem and RelyX U100). After standardized post-space preparation, the root dentine was pre-treated for dual-polymerizing resin cements and untreated for the other cements. The mixed luting cement paste was inserted into root canals with a spiral filler and applied to the post-surface that was seated into the root canal. After 7 days, the teeth were sectioned perpendicular to their long axis into 1-mm-thick sections and submitted to a push-out test (1 mm min(-1)). Statistical analyses were carried out by two-way anova and Tukey's tests (P < 0.05). RESULTS: The bond strength was significantly affected by the type of cement (P < 0.001) and by the longitudinal region of the root canal (P < 0.031). All cements exhibited gaps at the dentine/cement interface. CONCLUSIONS: The self-adhesive materials and the glass ionomer cements had the highest push-out bond strength values when compared with the dual-curing resin cement.

Classic cytogenetic and comparative genomic hybridisation (CGH) data on osteosarcomas have been reported extensively in the literature. However, the number of paediatric osteosarcoma cases studied below the age of 14 years remains relatively small. This study reports four new cases of paediatric osteosarcoma in patients aged 3 to 13 years, evaluated by classic cytogenetics and CGH analyses. Clonal chromosomal alterations were detected in all the cases and included structural rearrangements at 1p11-13, 1q11, 4q27-33, 6p23-25, 6q16-25, 7p13-22, 7q11-36, 11p10-15, 11q23, 17p11.2-13, 21p11, and 21q11-22. The CGH analysis revealed recurrent gains at 1p, 4q, 17p, and 21q and losses at 3q and 16p. Five amplification sites were observed at 1q11-23, 6p21, 8q13, 8q21.3-24.2, and 17p. The data are discussed and compared with other cytogenetic reports in the literature.
