Electrochemical biosensors for Salmonella: State of the art and challenges in food safety assessment

According to the recent statistics, Salmonella is still an important public health issue in the whole world. Legislated reference methods, based on counting plate methods, are sensitive enough but are inadequate as an effective emergency response tool, and are far from a rapid device, simple to use out of lab. An overview of the commercially available rapid methods for Salmonella detection is provided along with a critical discussion of their limitations, benefits and potential use in a real context. The distinguished potentialities of electrochemical biosensors for the development of rapid devices are highlighted. The state-of-art and the newest technologic approaches in electrochemical biosensors for Salmonella detection are presented and a critical analysis of the literature is made in an attempt to identify the current challenges towards a complete solution for Salmonella detection in microbial food control based on electrochemical biosensors.This work received financial support from the European Union (FEDER funds through COMPETE) and National Funds (FCT, Fundação para a Ciência e Tecnologia) through project UID/QUI/50006/2013.

O aborto é uma dor narcísica irreparável?

O artigo nasce de uma experiência de atendimento psicanalítico em grupo com grávidas que realizam pré-natal no HUB, Hospital Universitário de Brasília, por 18 meses totalizando 53 atendimentos. A escuta objetiva oportunizar, a partir da fala, um reposicionamento subjetivo. O texto gira em torno de alguns conceitos psicanalíticos como narcisismo, ambivalência, investimento no objeto, luto, melancolia e angústia, correlacionando-os com a gravidez e o aborto. O artigo narra algumas experiências de grávidas que, no passado, vivenciaram a dor narcísica do aborto e discute como a grávida pode superar o luto e tonar-se apta a investir em uma nova gravidez. Como investir num filho que remete aos abortos anteriores, que significam a impotência e o fracasso destas mulheres? Como ajudá-la a sonhar, a conceber uma representação deste filho para dar a ele a oportunidade de viver? Como ajudá-la a sustentar este desejo essencial? Os atendimentos pretendem ajudá-las a sonhar, a conceber uma representação do filho e a sustentar este desejo essencial de vida. Diversos casos clínicos são apresentados, contemplando mulheres em diversas fases da gestação. Cada uma delas descreve como enfrenta a possibilidade do aborto. Este artigo investiga a relação da grávida, em repetido risco de aborto, com o seu bebê. É possível a mulher superar a dor do aborto e tornar-se apta a investir em uma nova gravidez que chegue a termo? ____________________________________________________________________________________ ABSTRACTThe article results from an experience involving psychoanalytic sessions with a group of pregnant women undergoing pre-natal care at the University of Brasilia Hospital during 18 months, a total of 53 sessions. The objective of the listening sessions is to allow the subjects to reach a better understanding of their subjectivity. The text approaches psychoanalytical concepts such as narcissism, ambivalence, investment in the object, mourning, melancholy and anguish, relating them to pregnancy and miscarriage. The article describes experiences with pregnant women who, in the past, experienced the narcissistic pain of miscarriage and discusses how pregnant women can overcome their mourning and become apt to invest in a new pregnancy. How can these women invest in new children who remind them of previous miscarriages that symbolize their impotence and failure? How to help this woman dream, develop a representation of her child, so as to give him the chance of living? How to help her keep this essential desire? The sessions intend to help the women dream, develop a representation of the child and sustain this essential desire for life. Several clinical cases are shown, including women in different phases of pregnancy. Each one describes how to deal with the possibility of miscarriage. This article investigates the relationship between pregnant women, who present repetitive risk of miscarriage, and their child. Is it possible for a woman to overcome the pain of miscarriage and be ready to invest in a new successful pregnancy

School success: concept, factors and strategies

The Project "Beliefs, knowledge and practices of teachers" was developed as part of a multiple action plan intended to address school failure, developed by the Intermunicipal Community of Terras de Trás os Montes (CIM-TTM), Portugal. This article presents a part of the study devoted to its central theme: school success. From the theoretical research carried out it was realized that there is a multiplicity of "school successes", the explicitness of the concept in order to unveil the meanings that underlie the various statements being rare [1]. In the project carried out, the meaning assigned to it is centered upon the development of competences, seen according to the curriculum document The Profile of Students Leaving Compulsory Education [2], as complex combinations of knowledge, skills and attitudes, which children and young people should acquire as indispensable tools for exercising a full, active and creative citizenship. This project involved as participants the leaders (school cluster directors, class headmasters and curricular department coordinators) and the teachers of all levels and cycles of education of eleven school clusters integrated in the region covered by the CIM-TTM. In the part of the study here presented, group interviews were used with the leaders of each School group for data collection. For data analysis we used content analysis and considered a priori defined categories and shaped by the theory: meanings of school success, success factors and strategies to promote success. As results of the study, in relation to the meaning, factors and strategies of success, the following were highlighted: (i) relativity of the concept and some criticism of educational policies; (ii) association of the concept with attaining positive grades and student progress; (iii) concept defined according to the profile in the above-mentioned curriculum document; (iv) attention to the uniqueness of students; (v) indication of personal factors (students' future prospects and expectations), family and social factors as promoters of school success, and (v) indication of the educational policy on curricular flexibility as a favorable framework for the implementation of support measures and individualized teaching that contribute to the success of all students.This work was supported by FCT - Fundação para a Ciência e Tecnologia (Science and Technology Foundation) within the scope of Project UIDB/05777/2020info:eu-repo/semantics/publishedVersio

Diferenciação pedagógica: experiências de aprendizagens a partir das culturas locais

O projecto que a seguir se apresenta reflecte o trabalho realizado no âmbito do Projecto das Escolas Rurais, desenvolvido em parceria entre a Escola Superior de Educação de Bragança (ESEB), o Instituto das Comunidades Educativas (ICE) e as Comunidades Locais. Homenageia-se desta forma o Professor Joaquim Bairrão Ruivo, sócio fundador e presidente da Assembleia Geral do ICE durante longos anos. A contextualização do projecto centrou-se no concelho de Vinhais, meio rural do interior norte, onde a desertificação humana se faz sentir. Constituiu-se como principal objectivo a implementação de dinâmicas de acção potenciadoras da construção de espaços de envolvimento intergeracional que contemplassem a participação da escola e das comunidades rurais na partilha dos seus saberes e culturas. Tendo em conta a necessária (re)valorização do espaço rural assumiu-se o seu desenvolvimento como um processo social centrado nas potencialidades das comunidades locais. As estratégias foram definidas a partir do pressuposto que a acção directa no meio rural é uma tarefa complexa e multidimensional, só possível através de uma abordagem integradora e multidisciplinar que se realiza na confluência de diferentes olhares que estabelece elos de ligação na entrecruzada teia de relações que emergem dessas comunidades. A ESEB envolveu alunos da formação inicial que apoiaram o intercâmbio de jardins-de-infância (JI), escolas do 1º Ciclo do Ensino Básico (1ºCEB) e espaços comunitários de forma continuada, na dinamização de projectos educativos centrados no local. Emerge, do trabalhado realizado, que o contacto intencionalizado tem proporcionado uma maior interacção das crianças com as comunidades de pertença e grupos mais alargados ao envolverem-se em experiências de aprendizagem centradas na descoberta do meio. Além disso o contacto dos formandos da ESEB com as comunidades rurais permitiu-lhe o conhecimento de uma realidade diferente, reconhecendo a importância dos contextos no desenvolvimento de projectos educativos sustentados na cultura local e sustentadores de vivências de cidadania

Tratamiento mecánico y químico de la periimplantitis experimental. Estudio controlado preclínico “in vivo”

El objetivo de este estudio fue evaluar el efecto combinado de un cepillo de titanio con el uso concomitante de agentes químicos en el tratamiento quirúrgico de la periimplantitis experimental. MATERIAL Y MÉTODOS: Se colocaron 6 implantes en la mandíbula de 8 perros Beagle (unidad de análisis), tres meses después de la extracción de todos los premolares mandibulares. La periimplantitis experimental se indujo durante los siguientes 3 meses. Los defectos óseos resultantes fueron aleatoriamente asignados a 3 grupos de tratamiento: 1) TiBrushTM + hipoclorito de sodio + clorhexidina (TBH), 2) TiBrushTM + clorhexidina (TB), 3) punta de ultrasonidos + clorhexidina (US). El implante distal en cada hemimandíbula fue usado como control, y en él no se realizó ningún tratamiento. Tres meses después de la cicatrización se tomaron medidas clínicas, radiológicas e histológicas. RESULTADOS: Todos los métodos de descontaminación consiguieron una mejoría estadísticamente significativa de todos los parámetros clínicos y radiológicos estudiados. El análisis histomorfométrico reveló diferencias entre los grupos de tratamiento en términos de altura de hueso reticular (variable principal del estudio), pero estas diferencias no fueron estadísticamente significativas. Sin embargo si hubo diferencias entre los grupos en relación a la inflamación, profundidad del defecto óseo y relleno del defecto, sin diferencias estadísticamente significativas entre los grupos 1 (TBH) y 2 (TB). CONCLUSIONES: La resolución de la periimplantitis después de la cirugía de acceso y la descontaminación de la superficie de los implantes con los cepillos de titanio y el empleo o no de hipoclorito de sodio es posible. Sin embargo el empleo concomitante de hipoclorito de sodio tiene un efecto muy limitado en los resultados del tratamiento

Conscious Material Choices. A Systemic Approach to Reframing our Relationship with Materials and to Accelerating the Positive Impact Future

We are immersed in a sustainability crisis fueled by our “take-makewaste” industrial model1 and our throwaway culture2. We need an urgent, seismic shift from linear growth to sustainable prosperity. Positive impact can be at the core of new ideas, projects and business models, integrating all aspects of sustainability and creating tangible, long-lasting value. We can move positive impact front and center in our creative conversations with materials. Using systems thinking, material professionals can imagine a ‘new normal’. Leverage points to activate change include a reframed relationship with materials, a new modus operandi and new opportunities leveraging on circularity thinking and technology. Beyond the immediate opportunities that making conscious material choices can unlock in products and buildings, we can radically accelerate the positive impact future

The volatile composition of Portuguese propolis towards its origin discrimination

The volatiles from thirty six propolis samples collected from six different geographical locations in Portugal (mainland, Azores archipelago and Madeira Island) were evaluated. Populus x canadensis Moenchen leaf-buds and Cistus ladanifer L. branches essential oils were comparatively analysed. The essential oils were isolated by hydrodistillation and analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS). Cluster analysis based on propolis samples volatiles chemical composition defined three main clusters, not related to sample site collection. Cluster I grouped 28 samples with high relative amounts of oxygen-containing sesquiterpenes (20-77%), while cluster II grouped 7 samples rich in oxygen-containing monoterpenes (9-65%) and the only sample from cluster III was monoterpene hydrocarbons rich (26%). Although Populus x canadensis and Cistus ladanifer were associated as resin sources of Portuguese propolis, other Populus species as well as plants like Juniperus genus may contribute to the resin in specific geographical locations.Soraia I.
