A vaccinia virus promoter was evaluated for regulation of a foreign gene in fowlpox virus by a transient expression assay. Fowlpox virus-infected quail cells, transfected with plasmid DNA containing chloramphenicol acetyltransferase (CAT) gene ligated to a vaccinia virus promoter, expressed CAT activity. No CAT activity was detected either in uninfected cells or fowlpox virus-infected cells. These results indicated that a heterologous vaccinia virus promoter can regulate expression of a foreign gene in fowlpox virus.

Student guidance is an always desired characteristic in any educational system, butit represents special difficulty if it has to be deployed in an automated way to fulfilsuch needs in a computer supported educational tool. In this paper we explorepossible avenues relying on machine learning techniques, to be included in a nearfuture -in the form of a tutoring navigational tool- in a teleeducation platform -InterMediActor- currently under development. Since no data from that platform isavailable yet, the preliminary experiments presented in this paper are builtinterpreting every subject in the Telecommunications Degree at Universidad CarlosIII de Madrid as an aggregated macro-competence (following the methodologicalconsiderations in InterMediActor), such that marks achieved by students can beused as data for the models, to be replaced in a near future by real data directlymeasured inside InterMediActor. We evaluate the predictability of students qualifications, and we deploy a preventive early detection system -failure alert-, toidentify those students more prone to fail a certain subject such that correctivemeans can be deployed with sufficient anticipation.

The chemistry of today’s concrete mixture designs is complicated by many variables, including multiple sources of aggregate and cements and a plethora of sometimes incompatible mineral and chemical admixtures. Concrete paving has undergone significant changes in recent years as new materials have been introduced into concrete mixtures. Supplementary cementitious materials such as fly ash and ground granulated blast furnace slag are now regularly used. In addition, many new admixtures that were not even available a few years ago now have widespread usage. Adding to the complexity are construction variables such as weather, mix delivery times, finishing practices, and pavement opening schedules. Mixture materials, mix design, and pavement construction are not isolated steps in the concrete paving process. Each affects and is affected by the other in ways that determine overall pavement quality and long-term performance. Equipment and procedures commonly used to test concrete materials and concrete pavements have not changed in decades, leaving serious gaps in our ability to understand and control the factors that determine concrete durability. The concrete paving community needs tests that will adequately characterize the materials, predict interactions, and monitor the properties of the concrete.

Estudo transversal descritivo exploratório que objetivou analisar forças impulsoras e restritivas para trabalho em equipe em um Centro de Material e Esterilização (CME) de um hospital escola, a partir de aproximação da Teoria de Campo de Kurt Lewin, em Goiânia, Goiás. Participaram 35 profissionais, que responderam a um questionário autoaplicável, baseado na referida teoria, que prevê que situações grupais são permeadas por forças que mobilizam positiva ou negativamente seus movimentos e dizem respeito ao envolvimento do sujeito (Eu), a interação do grupo (Outro) e ao ambiente de trabalho (Ambiente). Foi utilizada análise de conteúdo no tratamento dos dados distribuídos nas dimensões predefinidas. Os resultados consolidaram 1.990 registros, categorizados como maioria (59,3%) de forças impulsoras, predominantes na dimensão Eu. Nas dimensões Outro e Ambiente observou-se equilíbrio entre as forças. O delineamento do campo de forças permitiu uma visão objetiva, concreta das limitações, potenciais da equipe estudada e possibilidades para promover mudanças.

Recommendations and laws do not always contain specific and clear provisions on the use of cadaveric material in research, and even more rarely do they address explicitly the ethical issues related to research on material obtained during forensic autopsy. In this article we analyse existing legal frameworks in Europe by comparing the legal provisions in 2 European Countries which are member states of the Council of Europe, the UK and Switzerland. They were chosen because they have distinct legal frameworks that make comparisons interesting. In addition, the detailed laws of the UK and a specific law project and national ethical recommendations in Switzerland permit us to define more clearly the legal range of options for researchers using cadaveric material obtained during forensic investigations. The Human Tissue Act 2004 in England, Wales and Northern Ireland, its Scottish equivalent with the same title (2006) and the national ethical guidelines in Switzerland all require consent from the deceased person, an appropriate relative or a person with power of attorney for healthcare decisions before cadaveric biological material can be obtained and used for research. However, if the purpose of the autopsy is purely forensic, no such authorization will be sought to carry out the autopsy and related analyses, which might include genetic testing. In order to be allowed to carry out future research projects, families need to be approached for informed consent, unless the deceased person had left written directives including permission to use his or her tissues for research.

O presente trabalho trata-se de estudo de corte transversal, com objetivo de avaliar a conduta dos profissionais de enfermagem vítimas de acidentes com material biológico, do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, no estado de São Paulo, referente ao atendimento e ao seguimento clínico especializado. A população foi composta por 1.215 profissionais de enfermagem, entrevistados entre os anos de 2010 e 2011, dos quais 636 (52,3%) sofreram acidentes com material biológico e 182 (28,6%) não procuraram atendimento no serviço especializado. O motivo mais frequentemente relatado foi atribuir pouco risco ao acidente. Assim, acredita-se que os motivos alegados pelos profissionais para não procurarem o atendimento, para não completarem a terapêutica e nem o seguimento clínico podem contribuir para a proposição de estratégias capazes de aumentar a adesão às medidas profiláticas após exposição ocupacional a material biológico.

The irritable bowel syndrome has been considered a diagnosis of exclusion and multiple diagnostic procedures were often performed in order to exclude an organic disorder. Nowadays, studies show that in young patients, who match the clinical criteria of irritable bowel syndrome and show no alarm features, the prevalence of underlying organic disorders is low, or at least not higher than in the general population. Based on these findings, current recommendations suggest that no extra diagnostic tests have to be performed in those patients, apart from the serological tests in search of celiac disease, which are recommended for patients presenting an irritable bowel syndrome with diarrhea or a mixed-type irritable bowel syndrome.

We study the role of domestic financial institutions in sustaining capital flows to the private and public sector of a country whose government can default on its debt. As in recent public debt crises, in our model public defaults weaken banks' balance sheets, disrupting domestic financial markets. This effect leads to a novel complementarity between private capital inflows and public borrowing, where the former sustain the latter by boosting the government's cost of default. Our key message is that, by shaping the direction of private capital flows, financial institutions determine whether financial integration improves or reduces government discipline. We explore the implications of this complementarity for financial liberalization and debt-financed bailouts of banks. We present some evidence consistent with complementarity.

Objective: To describe the barriers and facilitator factors to follow the attention flow of professionals injured by biological material in the worker perspective. Method: Qualitative descriptive study with data collected through individual interviews with 18 injured workers, assisted in reference public units in the city of Goiânia. The content analysis was carried out with assistance of the ATLAS.ti 6.2 software, under the work organization and subjective perspectives. Results: From the interviews regarding the barriers and facilitator factors emerged the categories: organizational structure, Support from close people, and Knowledge influence. Conclusion: The organized services have enabled more qualified consultations and the workers follow-up, which caused a satisfaction feeling in relation to the working environment.
