A partir da primeira publicação de caráter musicológico de música brasileira do século XVIII, realizada em 1951 por Francisco Curt Lange (Archivo de Música Religiosa de la Capitania Geral das Minas Gerais), surgiram iniciativas brasileiras que manifestaram as mais variadas propostas editoriais. O estudo das edições produzidas no país nas últimas cinco décadas revela várias dualidades, dentre as quais as dez mais importantes serão abordadas neste artigo: 1) publicação ou circulação informal; 2) Gesamtausgaben ou Denkmähler; 3) edição acadêmica ou edição prática; 4) fontes de um único acervo ou de vários; 5) obra isolada ou coletânea; 6) trabalho individual ou trabalho de equipe; 7) obras inéditas ou já divulgadas; 8) financiamento privado ou de instituições governamentais; 9) apenas partitura ou partituras e partes; 10) divulgação em papel ou em meios eletrônicos. Além da identificação dessas dualidades, o objetivo deste artigo é tentar compreender o seu significado e relacioná-las às atuais perspectivas editoriais da música antiga no país.

OBJETIVO: A insuficiência renal aguda (IRA) no pósoperatório (PO) de cirurgia cardíaca é complicação grave. O objetivo deste trabalho é avaliar o tempo de circulação extracorpórea (CEC) como fator de risco para IRA. MÉTODO: Foram avaliados 116 pacientes de um único centro, submetidos a cirurgia cardíaca com CEC. Foram avaliados os dados demográficos, características clínicas, variáveis intra e pós-operatórias. A creatinina sérica e o clearance de creatinina foram avaliados até o 5ºPO. IRA foi definida como necessidade de diálise. Os pacientes foram estratificados em dois grupos: grupo CEC< 70 min e grupo CEC> 90min. RESULTADOS: O aumento médio da creatinina sérica no PO foi 0,18+0,41 no grupo CEC<70min e 0,42+0,44 no grupo CEC>90min (p=0,005). Diálise foi necessária em 1,3% dos pacientes do grupo CEC<70min, e em 12,5% do grupo CEC> 90min (p=0,018). O risco relativo para diálise foi 1,12 (IC 95%, 1,00-1,20) para CEC>90min. Não houve diferença para mortalidade (5,2 versus 7,5%, p=0,631). CONSLUSÃO: O desenvolvimento de IRA no pós-operatório de cirurgia cardíaca foi observado em pacientes com tempo de CEC superior a 90 minutos, embora o clearance de creatinina não tenha demonstrado alteração entre os grupos.

In 18 dogs, previously anesthetized with sodium pentobarbital for the surgical preparation, catheterism and monitoring, the action of sodium pentobarbital (7.5 mg/kg) and enflurane (1.5 - 2%) in the liver circulation was studied. Measurements of the following parameters were made in four different times, before and 15, 30 and 60 min after the drug administration. By direct determination: hepatic artery flow, portal vein flow, mean pressure of the abdominal aorta, peripheral arterial pressure (mean), pressure in the caudal cava vein, portal pressure; and by indirect determination: total flow, arterial-cava gradient, portal-cava gradient, resistance in the hepatic artery territory, resistance in the territory of the portal vein, and total resistance. Based on the results, it is concluded that in the experiment's conditions: sodium pentobarbital doesn't change significantly the hepatic circulation, and enflurance produces a fall in the total hepatic flow, by reducing the portal flow, without alterations of the hepatic arterial flow. It diminishes the total hepatic resistance by diminishing the arterial resistance without alterations of the portal resistance; it diminishes the arterial-cava gradient in consequence of the reduction of the abdominal aorta pressure and of the portal pressure, but it seems that the caudal cava pressure is not altered. It also occurs a fall in the peripheral mean pressure.

The beachs of Santos are situated in Santos Bay, central portion of paulista coast, in São Paulo state. This beachs are frequently affected by cold fronts with winds and currents from the South. These fronts are responsible for the removal and transport of sediments (sand) in Santos beaches. In order to quantify this sedimentation the channels of Santos were analysed, due to their function as box colectors of sediments during storm events. The channels are filled by sands, which volume in channels 1 to 6 was estimated, by using the length, width and height of sand sedimented in the channels, in the event of 22-27 april 2005. The chanels 2, 3 and 1 presented the larger volumes of sands, confirming that the central and SW portion of the beaches of Santos present higher levels of sedimentation or re-sedimentation. That is due to the transport by ocean waves and currents and currents from the Channel of the Port of Santos. This central portion suffer invasion of marine water over street and buildings, caracterizated of geological rise area.

This work aims to express the production and consumption changes occurred in the State of São Paulo in line with the logistics, the systems of movement and the economic flows. The mentioned productive and consumption devolutions towards the interior just was possible in the fast rhythm, with the hierarchical combination of some basic elements, such as: 1) the logistics as strategy, planning and management (including in the concession of public services to the private enterprise) of transports, storage and communications; 2) the technological improvement of systems of movement (infrastructure and means of transportation) and 3) the economic flows (goods, services, informations, capital gains and people) in the territory. Thus, we go to an analysis of the impacts of the fifth logistics revolution and the alternatives between systems of movement and territorial fluidity in the service of corporative demands in the space pertaining to the State of São Paulo. © Copyright Scripta Nova, 2009.

Background and objectives: The introduction of extracorporeal circulation in clinical practice was decisive for the development of modern cardiovascular surgery. Addition of new procedures and equipment, however, brings inherent risks and complications. The objective of this report is to describe a malfunction of the oxygenation system and emphasize the importance of the interaction among the medical team members to prevent errors and complications. Case Report: During valve replacement and IVC correction surgery, we observed a darker shade of red in the blood on the exit of the oxygenator. Laboratory tests demonstrated severe acidosis and hypoxemia. The entire system was evaluated, but the cause of the malfunction was not found. Measures to reduce damage were successfully instituted. After the surgery, the whole system underwent technical evaluation. Conclusions: Interaction among the medical team members, early diagnosis, and immediate intervention were fundamental for a favorable outcome. © 2011 Elsevier Editora Ltda.
