OBJETIVO: Comparar a câmara de cintilação e sistema de coincidência (CC) com a ecocardiografia de estresse pela dobutamina (EED) na detecção de viabilidade miocárdica, utilizando-se a recuperação funcional como padrão de referência. MÉTODOS: Vinte e um pacientes com doença arterial coronária e disfunção grave do ventrículo esquerdo foram estudados prospectivamente, submetidos a EED e CC, antes da cirurgia de revascularização do miocárdio (RM), e a EED, três meses após. RESULTADOS: De 290 segmentos analisados, 83% encontravam-se acinéticos, 15%, hipocinéticos, e 2, discinéticos ao repouso. A EED identificou 68% destes segmentos como não-viáveis. A CC identificou 56% destes segmentos como normais (contratilidade alterada com metabolismo e perfusão preservada), 30% como viáveis (perfusão reduzida e metabolismo preservado) e 14%, como não-viáveis (ausência de metabolismo e perfusão). Entre os não-viáveis pela EED, a CC classificou 80% como normais ou viáveis e 19,9%, como não viáveis (p<0,001). A sensibilidade e especificidade da EED foram de 48,3% e 78,1%, respectivamente. A sensibilidade e especificidade da CC de 92,2% e 20,0%, respectivamente. A CC identificou maior proporção de recuperação funcional nos segmentos classificados como normais do que os viáveis e não-viáveis. CONCLUSÃO: A CC classificou como normal ou viável a maior parte dos segmentos não-viáveis pela EED. Na avaliação da recuperação funcional, três meses após a RM, a CC demonstrou uma alta sensibilidade, porém reduzida especificidade.

Multi-core processors is a design philosophy that has become mainstream in scientific and engineering applications. Increasing performance and gate capacity of recent FPGA devices has permitted complex logic systems to be implemented on a single programmable device. By using VHDL here we present an implementation of one multi-core processor by using the PLASMA IP core based on the (most) MIPS I ISA and give an overview of the processor architecture and share theexecution results.

Telecommunications and network technology is now the driving force that ensures continued progress of world civilization. Design of new and expansion of existing network infrastructures requires improving the quality of service(QoS). Modeling probabilistic and time characteristics of telecommunication systems is an integral part of modern algorithms of administration of quality of service. At present, for the assessment of quality parameters except simulation models analytical models in the form of systems and queuing networks are widely used. Because of the limited mathematical tools of models of these classes the corresponding parameter estimation of parameters of quality of service are inadequate by definition. Especially concerning the models of telecommunication systems with packet transmission of multimedia real-time traffic.

Mangas 'Bourbon' foram conservadas em câmara fria, a temperatura de 10º C, tendo recebido previamente os seguintes tratamentos em pós-colheita: 1) controle; 2) imersão por 10' em água a 55 C; 3) imersão por 5' a 50 C em solução de Benomyl a 0,025% de p.a.; 4) imersão por 5' a 50ºC em solução de Benomyl a 0,050%; 5) imersão por 5' a 55ºC em solução de Benomyl a 0,025% de p.a. e 6) imersão por 5' a 55ºC em solução de Benomyl a 0,050% de p.a. Os resultados indicaram que todos os tratamentos, com exceção do controle, foram eficientes no controle da antracnose. Quanto à ocorrência das podridões moles, constatou-se perdas de 44, 36, 20, 20, 4 e 8% do primeiro para o sexto tratamento, respectivamente. Assim ficou evidenciado que os tratamentos à mais alta temperatura, conjugados ao fungicida Benomyl, foram aqueles mais interessantes no tratamento em pós-colheita de manga 'Bourbon' .

Mammalian cancer as well as the Rous chicken sarcoma has been successfully transplanted into the anterior chamber of the eyes of guinea pigs. It was of interest, therefore, to see if the infectious myxomatosis of rabbits, another representative of the infectious tumors, could be grown in the anterior chamber of the guinea pig eye, and, if growth occurred, to compare the tumor's behaviour with that of growths of the above mentioned etiology. Forty-three full-grown guinea pigs from mixed stocks were used throughout, and seventy-eight heterologous transplantation experiments were performed. The grafts measuring less than 2 mm. in diameter were cut from the subcutaneous tissue in skin lesions of rabbits with infectious myxomatosis recently killed. The transfer to the anterior chamber was performed after the usual technique. Some degree of partial survival was found in 23,8% of the grafts, in which typical myxoma cells could be demonstrated fifteen days after the transplantation. The transplant apparently does not increase in size, differing in that respect from that of the Rous chicken sarcoma, which increases in size by 2 or 3 diameters in 2 weeks (Shrigley, Greene & Duran-Reynals, 1945). The virus was still alive in 26% of the grafts 21 days after transplantation, and was able to induce a typical disease when injected to normal rabbits. No alteration in the properties of the virus after growth in the guinea pig was noticed, and this also is different from what happens with the Rous chicken sarcoma.

Heterotranplantability of myxoma of rabbits was formely demonstrated when grafts from subcutaneous tissue in skin were used (MARGARINOS TÔRRES & RITA CARDOSOS, 1949). Better results are reported in this paper when grafts from the spleen of infected rabbits were employed. While grafts from normal spleen are almost completely absorbed in sixteen days, those from infected rabbits give origin to full-grown and vascularised tissue in which typical myxoma cells are predominant elements. Progressive growth of heterotransplantated myxoma cells is another similarity between infectious myxoma and malignant tumors. Formation of clear areas of circular contour (interference of a diffusible substance?) associated to myxomatous degeneration is very conspicuous. Peculiar changes of the ground substance, reticular and collagenous fibers (globular swelling, rosary and bulb formation) apparently related to myxomatous degeneration are described. An unexpected finding was the presence of typical intranuclear inclusion bodies in five among forty-eight grafts examined in the sixth day.

Background and Aims: IL28B polymorphisms, interferon (IFN)-gamma inducible protein-10 (IP-10) levels and the homeostasis model assessment of insulin resistance (HOMA-IR) score have been reported to predict rapid (RVR) and sustained (SVR) virological response in chronic hepatitis C (CHC), but it is not known whether these factors represent independent, clinically useful predictors. The aim of the study was to assess factors (including IL28B polymorphisms, IP-10 levels and HOMA-IR score) independently predicting response to therapy in CHC under real life conditions.Methods: Multivariate analysis of factors predicting RVR and SVR in 280 consecutive, treatment-naive CHC patients treated with pegylated IFN alpha and ribavirin in a prospective multicenter study.Results: Independent predictors of RVR were HCV RNA < 400,000 IU/ml (OR11.37; 95% CI 3.03-42.6), rs12980275 AA (vs. AG/GG) (OR 7.09; 1.97-25.56) and IP-10 (OR 0.04; 0.003-0.56) in HCV genotype 1 patients and lower baseline γ-glutamyl-transferase levels (OR = 0.02; 0.0009-0.31) in HCV genotype 3 patients. Independent predictors of SVR were rs12980275 AA (OR 9.68; 3.44-27.18), age < 40 yrs (OR = 4.79; 1.50-15.34) and HCV RNA < 400,000 IU/ml (OR 2.74; 1.03-7.27) in HCV genotype 1 patients and rs12980275 AA (OR = 6.26; 1.98-19.74) and age < 40 yrs (OR 5.37; 1.54-18.75) in the 88 HCV genotype 1 patients without a RVR. RVR was by itself predictive of SVR in HCV genotype 1 patients (32 of 33, 97%; OR 33.0; 4.06-268.32) and the only independent predictor of SVR in HCV genotype 2 (OR 9.0, 1.72-46.99; p=0.009) or 3 patients (OR 7.8, 1.43-42.67; p=0.01).Conclusions: In HCV genotype 1 patients, IL28B polymorphisms, HCV RNA load and IP-10 independently predict RVR. The combination of IL28B polymorphisms, HCV RNA level and age may yield more accurate pretreatment prediction of SVR. HOMA-IR score is not associated with viral response.

The aim of my speech is answering to the question if the Spanish Inheritance and Gift Tax is incompatible with the free movement of workers and capital. We are going to pay special attention to the European Commission’s request to Spain to change its Inheritance and Gift Tax provisions for Non-Residents or Assets held abroad. In order to answer to the question mentioned above five points will be explained. At first place I am going to describe the infrengement procedure established in the Article 258 that the EU Commission can follow when a Member State doesn’t comply with Community Law. At second place, we are going to explain what is the content of the EU Commission delivered on 5th of may 2010 regarding the spanish Inheritance and Gift Tax. Then, we will analise what establishes the Community Law regarding the freedom of workers and capital and how they are understood by the EU Court of Justice in similar cases. Finally, we are going to provide possible amendments that Spain could undertake.
