Changes in pH at the dentin surface in roots obturated with calcium hydroxide pastes

The purpose of this study was to determine the pH, after defined periods of time, in cavities prepared in the facial surface of the cervical, middle, and apical regions of roots obturated with calcium hydroxide pastes. Root canal instrumentation was performed on 40 recently extracted, single-rooted human teeth. Cavities 1.5 mm in diameter and 0.75 mm in depth were prepared in the cervical, middle, and apical regions of the facial surface of each root. Teeth were randomly divided into four groups. One group was left unobturated and served as a control. The three remaining groups were obturated with either aqueous calcium hydroxide, calcium hydroxide mixed with camphorated monochlorophenol, or Pulpdent pastes. Access cavities and apical foramina were closed with Cavit. Each tooth was stored individually in a vial containing unbuffered isotonic saline. pH at the surface was measured in the cervical, middle, and apical cavities at 0 and 3, 7, 14, 21, 28, 45, 60, 90, and 120 days. Results indicate that hydroxyl ions derived from calcium hydroxide pastes diffused through root dentin at all regions over the experimental period of 120 days. The pattern of pH change at the tooth surface was similar in all regions of the root, regardless of the type of calcium hydroxide paste used. This was a rapid rise in pH from a control value of pH 7.6, to greater than pH 9.5 by 3 days, followed by a small decline to pH 9.0 over the next 18 days, before finally rising and remaining at, or above pH 10.0 for the remainder of the experimental period. Pulpdent paste in the apical region was the only exception in this pattern, producing a pH rise nearly one full unit below the other pastes, pH 9.3. These results indicate that, for all pastes tested, a high pH is maintained at the root surface for at least 120 days. Copyright © 1996 by The American Association of Endodontists.

Música do Norte: intelectuais, artistas populares, tradição e modernidade na formação da “MPB” no Pará (anos 1960 e 1970)

A presente dissertação trata da atuação de intelectuais (poetas, jornalistas, militantes, estudantes, folcloristas, antropólogos) e artistas populares na formação da chamada “MPB”, Música Popular Brasileira, no Pará. Entre meados da década de 1960 e de 1970, setores intelectualizados da classe média paraense iniciaram uma grande mobilização no sentido de atualizarem a música popular produzida em Belém aos debates políticos e estéticos que a MPB realizava no restante do país. Festivais foram realizados, grupos de poesia e música surgiram, atuações políticas se misturavam com posturas boemias e grande atividade artística. A nova intelectualidade buscava ao mesmo tempo fazer uma música moderna, mas pautada em elementos da cultura popular paraense ou amazônida. Em meio a novos artistas advindos destes setores da sociedade uma revisão da memória da música popular se fazia e antigos nomes eram incorporados a uma tradição. Concomitantemente a isso, o carimbó, que até então estava restrito às cidades e comunidades interioranas, surge em Belém como uma explosão musical e torna-se música consumida pelas rádios, TVs e indústria do disco. A urbanização deste gênero do folclore regional leva a um amplo debate sobre autenticidade, mercado e identidade cultural da região amazônica e do Pará em particular. Neste processo, artistas de extratos populares entram em cena dando sua contribuição à música popular do Norte. O amplo debate nos jornais sobre o carimbó (sua autenticidade ou sua degeneração frente ao mercado) se soma as atuações da jovem intelectualidade. Neste complexo contexto de múltiplas atuações surge uma MPB de feições regionais.

Quantitative EEG evaluation in patients with acute encephalopathy

Objetivos Investigar o uso do EEG quantitativo (qEEG) em pacientes com encefalopatias agudas (EAs ) e anormalidades da atividade de base no EEG. Método s pacientes foram divididos em prognóstico favorável (grupo A, 43 pacientes) e desfavorável (grupo B, 5 pacientes). O programa EEGLAB foi utilizado para a análise do qEEG. Um gráfico da potência espectral de todos os canais foi gerado para cada participante. Os dois grupos foram comparados estatisticamente. Resultados No grupo A, a análise espectral revelou picos (frequências teta e alfa) em 84% (38/45) dos pacientes. No grupo B, um pico espectral na frequência delta foi detectado em um paciente. Os pacientes remanescentes dos dois grupos não apresentaram picos espectrais. A análise estatística mostrou menores frequências registradas nos eletrodos posteriores dos pacientes do grupo B. Conclusão O qEEG pode ser útil na avaliação de pacientes com EAs auxiliando na determinação do prognóstico.

Características agronômicas, bromatológicas e econômicas de alturas de corte para ensilagem da cultura do milho

The aim was to evaluate agronomic, bromatologic and economical characteristics harvest heights for ensiling of corn. The trial was conducted in randomized block design and treatments corresponded to harvest heights of 20; 50; 80 and 110 cm from the soil surface. The agronomic evaluations were conducted 114 days after planting. The percentage of dry matter (DM) and productivity of stem, grain and participation of potassium remaining in the stem increased linearly with increasing cutting height (p<0.05). Therefore, the mass used at ensiling decreased proportionally with increasing cutting height (p<0.05). The silage quality was improved because of the increase in the cutting height. We observed higher crude protein (CP) content and energetic value in the silage harvested at 110 cm from the soil surface, while there was lower fiber content. However, silages produced with plants harvested at 110 cm from the soil surface showed the highest production cost (4.47 times greater than cycling through K in the remainder of the stem). The agronomic and bromatologic characteristics of corn silage improves with increasing cutting height, but the increase cutting height unfeasible economically the practice silage when the generation of final products is not computed. Thus, it is recommended that the cutting height of the corn plant is at most 50 cm.

Uso de plasma rico em plaquetas em úlceras de córnea em cães

This study aims to clinically and macroscopically evaluate the adjuvant therapy with platelet-rich plasma in the form of eyedrops or clot, for corneal ulcers in dogs treated at the Veterinary Ophthalmology Service. We analyzed 20 eyes diagnosed with ulcerative keratitis, divided into two experimental groups. The eyedrop group (GC) was composed of eyes treated topically with eyedrops of autologous plateletrich plasma (PRP), and the clot group (GT) was composed of eyes treated with a platelet-rich clot and covered with a third eyelid for retention of the clot. The groups were evaluated by clinical and macroscopic analysis and by the analysis of epithelial defect reduction, at different times, at three, five, ten, 15 and 30 days, except for the third day in GT. The coverage of the third eyelid was removed on the fifth day. In both groups the inflammation signs reduced, there was an improvement in ocular sensibility and proper repair of epithelial defect. All GT eyes and 70% GC eyes showed complete healing on the fifth day, the remainder of GC completed healing on the tenth day. PRP in the form of eyedrops and clot is an excellent adjuvant therapy to be instituted in the clinical treatment for corneal ulcer in dogs, because it decreases the inflammatory signs and the ocular pain and it potentially assists in healing epithelial defects.

Sistema de Informações Geográficas aplicado ao diagnóstico do uso da terra da bacia hidrográfica do Córrego São Caetano - Botucatu (SP)

The study aimed to obtain the land use of the watershed Stream São Caetano - Botucatu (SP), through the satellite image. The cartographic databases were: planialtimetric letter in digital format (IBGE) used in georeferencing, and satellite image. Geographic Information Systems (GIS) -IDRISI Selva was use to perform the image georeferencing and to do the final thematic map. In the software CAD - CartaLinx, it was performed the delimitation of the area under study (boundary, drainage network and areas of use and coverage). The land use of the watershed showed that pasture was the class which occupied most of the area, with 34.51% (1117,94 ha), the remainder of the area was urban (692,19ha), forests (809,79ha), cultures (599,96ha) and a very small part of reforestation (19,53ha). The use of remote sensing and geoprocessing were very satisfactory in the present work. Technologies must be increasingly used in agricultural and environmental studies, because technological tools, such as Geographic Information System (GIS), present speed, efficiency, reliable results, helping in increasing sustainability

Compressed Air, Wooden Clappers, and Other Non-Traditional Methods for Dispersing European Starlings from an Urban Roost

During autumn 2003, several thousand European starlings (Sturnus vulgaris) began roosting on exposed I-beams in a newly constructed, decorative glass canopy that covered the passenger pick-up area at the terminal building for Cleveland Hopkins International Airport, Ohio. The use of lethal control or conventional dispersal techniques, such as pyrotechnics and fire hoses, were not feasible in the airport terminal area. The design and aesthetics of the structure precluded the use of netting and other exclusion materials. In January 2004, an attempt was made to disperse the birds using recorded predator and distress calls broadcast from speakers installed in the structure. This technique failed to disperse the birds. In February 2004, we developed a technique using compressed air to physically and audibly harass the birds. We used a trailer-mounted commercial air compressor producing 185 cubic feet per minute of air at 100 pounds per square inch pressure and a 20-foot long, 1-inch diameter PVC pipe attached to the outlet hose. One person slowly (< 5 mph) drove a pick-up truck through the airport terminal at dusk while the second person sat on a bench in the truck bed and directed the compressed air from the pipe into the canopy to harass starlings attempting to enter the roost site. After 5 consecutive nights of compressed-air harassment, virtually no starlings attempted to roost in the canopy. Once familiar with the physical effects of the compressed air, the birds dispersed at the sound of the air. Only occasional harassment at dusk was needed through the remainder of the winter to keep the canopy free of starlings. Similar harassment with the compressor was conducted successfully in autumn 2004 with the addition of a modified leaf blower, wooden clappers, and laser. In conclusion, we found compressed air to be a safe, unobtrusive, and effective method for dispersing starlings from an urban roost site. This technique would likely be applicable for other urban-roosting species such as crows, house sparrows, and blackbirds.
