José Mourinho, The special one: A pedagogical case

The purpose of this work is to create a case to reflect about the leadership role of José Mourinho in Real Madrid CF, considering his successful background experiences in FC Porto, Chelsea FC and FC Inter. The case is based on the failure of the Special One in Real Madrid CF. This paper is mainly focused in the leadership process, charismatic leadership and contingency theory of leadership. Moreover it is intended to introduce concepts about the influence of leaders in the organizational culture, the management of human resources, and the role of a leader adapting to a different context.

Accident caused by Centruroides testaceus (DeGeer, 1778) (Scorpiones, Buthidae), native to the Caribbean, in Brazilian airport

Describes the case of a 6-year-old girl who was stung by a Centruroides testaceus, a scorpion native to the Lesser Antilles, in the Guarulhos International Airport, São Paulo, Brazil, as she disembarked from a flight coming from the Caribbean. The patient presented only local symptoms (a small area of erythema and pain at the sting site), which were resolved after a few hours with analgesics, without the need for antivenom. Physicians who treat patients stung by scorpions should be alert to the possibility of such accidents being caused by non native species, especially those cases that occur near airports or ports.

O contrato de Project Finance

Currently, Angola portrays a notorious economic growth and due to recent innovative legislations, it has become the major investment attracting pole, especially in Sub-Saharan Africa, having, thus, an extraordinary potentiality for a rapid and sustainable development, likely to place her in outstanding positions in the world economic ranking. Yet, such economic growth entails demanding levels of intensive investment in infrastructure, what has been reported of the Angolan Government to be unable to respond to, save if recurring to very high index of external debt, poisoning, in this way, the future budgeting of the country. Due to these infrastructure investment shortages, the cost of production remains highly onerous and the cost of life extremely unaffordable. On this account, the current study disserts about the contract of Project Finance; an alternative finance resource given as a viable solution for the private financing of infrastructure, aiming to demonstrate that such contractual figure, likewise the experience of several emerging economies and others, is a contract bid framework to take into account in today’s world. It refers to a financing technique – through which the Government may satisfy a common need (for example, the construction of a public domain or public servicing), without having to pay neither offer any collateral – based on a complex legal-financial engineering, arranged throughout a coalition of typical and atypical agreements, whereby it is mandatory to look back at the basic concepts of corporate law. More than just a simple financial study, the dissertation at stake analyses the nature and legal framework of Project Finance, which is a legally atypical and innominate contract, concluding that there is a relevant need for regulating and devoting a special legal regime in the Angolan jurisdiction for this promising legal form in the contemporary corporate finance world.

Treatment of American tegumentary leishmaniasis in special populations: a summary of evidence

We aimed to assess and synthesize the information available in the literature regarding the treatment of American tegumentary leishmaniasis in special populations. We searched MEDLINE (via PubMed), EMBASE, LILACS, SciELO, Scopus, Cochrane Library and mRCT databases to identify clinical trials and observational studies that assessed the pharmacological treatment of the following groups of patients: pregnant women, nursing mothers, children, the elderly, individuals with chronic diseases and individuals with suppressed immune systems. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The available evidence suggests that the treatments of choice for each population or disease entity are as follows: nursing mothers and children (meglumine antimoniate or pentamidine), patients with renal disease (amphotericin B or miltefosine), patients with heart disease (amphotericin B, miltefosine or pentamidine), immunosuppressed patients (liposomal amphotericin), the elderly (meglumine antimoniate), pregnant women (amphotericin B) and patients with liver disease (no evidence available). The quality of evidence is low or very low for all groups. Accurate controlled studies are required to fill in the gaps in evidence for treatment in special populations. Post-marketing surveillance programs could also collect relevant information to guide treatment decision-making.

A consagração dos naturais

“One cannot analyse a legal concept outside the economic and socio-cultural context in which it was applied” – such is the longstanding thesis of António Manuel Hespanha. I argue that Hespanha’s line of argument relative to legal concepts is also applicable, mutatis mutandis, to legal agents: the magistrates, advocates, notaries, solicitors and clerks who lived and exercised their professions in a given time and place. The question, then, is how to understand the actions of these individuals in particular contexts – more specifically in late 18th century and 19th century Goa. The main goal of the present thesis was to comprehend how westernized and Catholic Goan elite of Brahman and Chardó origin who provided the majority of Goan legal agents used Portuguese law to their own advantage. It can be divided into five key points. The first one is the importance of the Constitutional liberalism regime (with all the juridical, judicial, administrative and political changes that it has brought, namely the parliamentary representation) and its relations with the perismo – a local political and ideological tendency nurtured by Goan native Catholic elite. It was explored in the chapter 2 of this thesis. The second key point is the repeated attempts made by Goan native Catholic elite to implement the jury system in local courts. It was studied in the chapter 3. Chapter 4 aims to understand the participation of the native Catholic elite in the codification process of the uses and traditions of the indigenous peoples in New Conquests territory. The fourth key point is the involvement of those elites not only in the conflict of civil and ecclesiastical jurisdictions but also in the succession of the Royal House of Sunda. It was analyzed in the chapter 5. The functions of an advocate could be delegated to someone who, though lacking a law degree, possessed sufficient knowledge to perform this role satisfactorily. Those who held a special licence to practice law were known as provisionários (from provisão, or licence, as opposed to the letrados, or lettered). In the Goa of the second half of the 18th century and the 19th century, such provisionários were abundant, the vast majority coming from the native Catholic elite. The characteristics of those provisionários, the role played by the Portuguese letrados in Goa and the difficult relations between both groups were studied in the chapter 6.

A generic treatment of Alismatidae in the Neotropics with special reference to Brazil

A Subclasse Alismatidae nos neotrópicos é composta de nove famílias com 11 gêneros das quais, nove ocorrem na bacia amazônica e cinco no Brasil extra-amazônico. Apenas duas famílias não estão presentes no Brasil e mais duas ausentes da Amazônia brasileira. Este trabalho apresenta descrições detalhadas das famílias e gêneros, além de comentários sobre distribuição geográfica dos gêneros. As famílias estão organizadas na sequência sistemática que nós aceitamos. Os gêneros de cada família estão organizados em ordem alfabética i=sem significado sistemático. Fornecemos desenhos de pelo menos um gênero para cada família. Referências importantes -- tais como revisões genéricas, levantamentos da literatura, ou monografias de áreas neotropicais — estão relacionadas no início de cada tratamento a nível de família. As excelentes coleções do Projeto Flora Amazônica foram de importância decisiva para nosso trabalho-, sem elas não poderiamoi fazer um tratamento genérico completo para toda a região neotrópica.

Terapia celular com células mesenquimais por via intracoronária: contributos do estudo invasivo da microcirculação coronária

RESUMO: Introdução - A utilização de células e das suas propriedades para o tratamento das doenças cardiovasculares, é uma promessa para o futuro e talvez a única forma de ultrapassar algumas das insuficiências das terapêuticas atuais. A via de entrega das células mais utilizada na investigação tem sido a intracoronária, ganhando a microcirculação especial relevância, por ser onde ocorre a primeira interação com o tecido nativo. As células estaminais mesenquimais (CEM) têm propriedades que as tornam particularmente aptas para a Terapia Celular, mas as suas dimensões, superiores ao diâmetro dos capilares, tem motivado controvérsia quanto à sua entrega intracoronária. A cardiologia de intervenção tem atualmente técnicas que permitem a avaliação em tempo real e in vivo do estado da microcirculação coronária. A determinação do índice da resistência da microcirculação (IRM) fornece informação sobre a circulação dos pequenos vasos, de forma independente da circulação coronária e do estado hemodinâmico, mas a aplicabilidade clínica deste conhecimento encontra-se ainda por definir. Objectivos Esclarecer o potencial do IRM no estudo dos efeitos do transplante de CEM por via intracoronária. População e Métodos . Estudo pré-clínico com modelo animal (suíno) desenvolvido em 3 fases. Na Primeira Fase foram utilizados 8 animais saudáveis para estudar e validar a técnica de determinação de estudo da microcirculação. Efetuou-se a determinação do IRM com duas doses diferentes de papaverina para a indução da resposta hiperémica máxima (5 e 10 mg) e após a disfunção da microcirculação com injeção intracoronária de microesferas de embozene com 40 μm de diâmetro. Na Segunda Fase foram utilizados 18 animais saudáveis, randomizados em grupo controlo e grupo recetor de 30 x 106 CEM por via intracoronária. Foram avaliados de forma cega o IRM, a pressão aórtica, o fluxo coronário epicárdico e a ocorrência de alterações electrocardiográficas. Na Terceira Fase foram utilizados 18 animais, com enfarte agudo do miocárdio provocado (EAM), randomizados em grupo controlo, grupo recetor de CEM expandidas de forma convencional e grupo recetor de CEM expandidas com metodologia inovadora e de menores dimensões. Foi realizada uma exploração da dose/efeito com infusão faseada de 10 x 106, 15 x 106 e 20 x 106 CEM, com determinação do IRM, da pressão aórtica, do fluxo coronário epicárdico e da ocorrência de alterações eletrocardiográficas. Quatro semanas após a entrega das células foi novamente avaliado o IRM e foi efetuado o estudo anatomopatológico dos animais na procura de evidência de neoangiogénese e de regeneração miocárdica, ou de um efeito positivo da resposta reparadora após o enfarte. Resultados Nas 3 fases todos os animais mantiveram estabilidade hemodinâmica e eletrocardiográfica, com exceção da elevação de ST de V1-V3 verificada após a injeção das microesferas. Na Primeira Fase as duas doses de papaverina induziram uma resposta hiperémica eficaz, sem tradução com significado na determinação do IRM (variação da pressão distal de - 11,4 ± 5 e de - 10,6± 5 mmHg com as doses de 5 e 10 mg respetivamente (p=0,5). Com a injeção das microesferas o IRM teve uma elevação média de 310 ± 190 %, para um valor médio de 41,3 ± 16 U (p = 0,001). Na Segunda Fase não houve diferenças significativas dos parâmetros hemodinâmicos, do fluxo epicárdico e da avaliação eletrocardiográfica entre os dois grupos. O IRM de base foi semelhante e após a infusão intracoronária observou-se uma elevação expressiva do IRM nos animais que receberam células em comparação com o grupo controlo (8,8 U ± 1 vs. 14,2 U ± 1,8, P=0,02) e quanto ao seu valor de base (aumento de 112%, p=0,008). Na terceira Fase não houve novamente diferenças significativas dos parâmetros hemodinâmicos, do fluxo epicárdico e da avaliação eletrocardiográfica entre os três grupos. Houve uma elevação do IRM nos animais que receberam células a partir da 2ª dose (72% nas células convencionai e 108% nas células inovadoras) e que se manteve com a 3ª dose (100% nas células convencionais e 88% nas inovadoras) com significado estatístico em comparação com o grupo controlo (p=0,034 com a 2ªdose e p=0,024 com a 3ª dose). Quatro semanas após a entrega das CEM observou-se a descida do IRM nos dois grupos que receberam células, para valores sobreponíveis aos do grupo controlo e aos valores pós-EAM. Na avaliação anatomopatológica e histológica dos corações explantados não houve diferenças entre os três grupos. Conclusões O IRM permite distinguir alterações da microcirculação coronária motivadas pela entrega intracoronária de CEM, na ausência de alterações de outros parâmetros clínicos da circulação coronária utilizados em tempo real. As alterações do IRM são progressivas e passíveis de avaliar o efeito/dose, embora não tenha sido possível determinar diferenças com os dois tipos de CEM. No nosso modelo a injeção intracoronária não se associou a evidência de efeito benéfico na reparação ou regeneração miocárdica após o EAM.---------------------------- ABSTRACT: ABSTRACT Introduction The use of cells for the treatment of cardiovascular disease is a promise for the future and perhaps the only option to overcome some of the shortcomings of current therapies. The strategy for the delivery of cells most often used in current research has been the intracoronary route and due to this microcirculation gains special relevance, mainly because it is the first interaction site of transplanted cells with the native tissue. Mesenchymal stem cells (MSC) have properties that make them suitable for Cell Therapy, but its dimensions, larger than the diameter of capillaries, have prompted controversy about the safety of intracoronary delivery. The interventional cardiology currently has techniques that allow for real-time and in vivo assessment of coronary microcirculation state. The determination of the index of microcirculatory resistance index (IMR) provides information about small vessels, independently of the coronary circulation and hemodynamic status, but the clinical applicability of this knowledge is yet to be defined. Objectives To clarify the potential use of IMR in the study of the effects of MSC through intracoronary transplantation. Population and Methods Preclinical study with swine model developed in three phases. In Phase One 8 healthy animals were used to study and validate the IMR assessment in our animal model. IMR was assessed with two different doses of papaverine for inducing the maximal hyperaemic response (5 and 10 mg) and microcirculation dysfunction was achieved after intracoronary injection with embozene microspheres with 40 μm in diameter. In Phase Two we randomized 18 healthy animals divided between the control group and the one receiving 30 x 106 MSC through an intracoronary infusion. There we blindly evaluated IMR, the aortic pressure, the epicardial coronary flow and the occurrence of ECG changes. In Phase Three we used 18 animals with a provoked acute myocardial infarction (AMI), randomized into a control group, a MSC expanded conventionally receiver group and a MSC expanded with an innovative methodology receiver group. There was a stepwise infusion with doses of 10 x 106, 15 x 106 and 20 x 106 MSC with determination of IMR, the aortic pressure, the epicardial coronary flow and occurrence of electrocardiographic abnormalities. Four weeks after cell delivery we again measured the IMR and proceeded with the pathological study of animals in the search for evidence of neoangiogenesis and myocardial regeneration, or a positive effect in the reparative response following the infarction. Results All animals remained hemodynamically stable and with no electrocardiographic abnormalities, except for the ST elevation in V1-V3 observed after injection of the microspheres. In Phase One the two doses of papaverine achieved an hyperemic and effective response without significant differences in IMR (variation of the distal pressure -11.4 ± 5 and -10.6 ± 5 mmHg with the doses of 5 and 10 mg respectively (p = 0.5). With the injection of the microspheres the IMR had an average increase of 310 ± 190% for an average value of 41.3 ± 16 U (p = 0.001). In the second phase there were no significant differences in hemodynamic parameters, epicardial flow and electrocardiographic assessment between the two groups. The baseline IMR was similar and after intracoronary infusion there was a significant increase in animals receiving cells compared with the control group (8.8 ± U 1 vs. 14.2 ± 1.8, p = 0.02) and with their baseline (112% increase, p = 0.008). In the third phase again there were no significant differences in hemodynamic parameters, the epicardial flow and electrocardiographic evaluation between the three groups. There was a significant increase in IMR in animals that received cells from the 2nd dose (72% in conventional cells and 108% in the innovative cells) that remained with the 3rd dose (100% in conventional cells and 88% in the innovative) with statistical significance compared with the control group (p = 0.034 with 2nd dose, p = 0.024 with 3rd dose). Four weeks after delivery of the MSC we observed the fall of the IMR in the two groups that received cells with values overlapping those of the control group. In pathological and histological evaluation of removed hearts there were no differences among the three groups. Conclusions The IMR allows for the differentiation of changes in coronary microcirculation motivated by intracoronary delivery of MSC in the absence of modification in other clinical parameters. IMR changes are progressive and enable the evaluation of the effect / dose, though it has not been possible to determine differences in the two types of MSC. In our model, intracoronary injection of MSC was not associated with evidence of repair or myocardial regeneration after AMI.

Diversity of the land resources in the Amazonian State of Rondônia, Brazil

Conflicting opinions are recorded in the literature concerning the suitability of Amazon lands for sustainable agriculture following deforestation. This article has been written to shed light on this question by summarizing climate, landform, soil and vegetation features from the findings of a land resource study of the Brazilian state of Rondônia in south-west Amazonia. The work, which followed the World Soils and Terrain Digital Database (SOTER) methodology, was financed by the World Bank. During the course of the survey special emphasis was given to studying soils; 2914 profiles were analyzed and recorded. The study identified a complex pattern of land units with clear differences in climate, landform, soils and native vegetation. Forested areas mosaic with lesser areas of natural savannas. The latter occur on both poorly-drained and well-drained, albeit nutrient deficient sandy soils. The tallest and most vigorous forests or their remnants were seen growing on well-drained soils formed from nutrient-rich parent materials. Many of these soils could, or are being used for productive agriculture. Soils developed on nutrient-poor parent materials support forests that are significantly lower in height, and would require large lime and fertilizer inputs for agriculture. Low forests with high palm populations and minor areas of wet land savannas cover the poorly drained soils. It is evident that forest clearing in the past was indiscriminant; this cannot be condoned. The diversity of land conditions found throughout Rondônia would suggest that many past studies in the Amazon have simply been too broad to identify significant soil differences.

Leaf anatomical features of three Theobroma species (Malvaceae s.l.) native to the Brazilian Amazon

Theobroma species have economic importance due to their use in the cosmetic and food industries, mainly in the production of chocolate. However, the anatomy of their vegetative structures remains poorly studied. The goal of this study was to describe the anatomical features of Theobroma grandiflorum, T. speciosum and T. subincanum to contribute to the biological knowledge of these species, as well as provide support to the biotechnological studies of native fruit plants of the Amazon. Leaves at different developmental stages were collected and analyzed under light microscopy and scanning electron microscopy. Sessile and stalked stellate trichomes and digitiform glandular trichomes were observed in the expanded leaves of T. grandiflorum and T. subincanum. These species were also similar in the morphology of the midrib, the organization of the mesophyll and the presence of starch grains in the midrib pith cells. Claviform glandular trichomes and mucilage cells in the epidermis occurred only in the expanded leaves of T. speciosum. The presence of mucilage secretory trichomes in shoot apices (colleters) of all species is a new finding for the genus Theobroma.

Closed hybrid hierarchical reservoirs based on the deconstruction of the cellular native microenvironment

The stem cell niche organization and dynamics provide valuable cues for the development of mimetic environments that could have potential to stimulate the regenerative process. We propose the use of biodegradable biomaterials to produce closed miniaturised structures able to encapsulate different cell types or bioactive molecules. In particular, capsules are fabricated using the so-called layer-by-layer technology, where the consecutive (nano-sized) layers are well stabilized by electrostatic interactions or other weak forces. Using alginate-based spherical templates containing cells or other elements (e.g. proteins, magnetic nanoparticles, microparticles) it is possible to produce liquefied capsules that may entrap the entire cargo under mild conditions. The inclusion of liquefied micropcapsules may be used to produce hierarchical compartmentalised systems for the delivery of bioactive agents. The presence of solid microparticles inside such capsules offers adequate surface area for adherent cell attachment increasing the biological performance of these hierarchical systems, while maintain both permeability and injectability. We demonstrated that the encapsulation of distinct cell types (including mesenchymal stem cells and endothelial cells) enhances the osteogenic capability of this system, that could be useful in bone tissue engineering applications.

Introduction to special Issue: future priorities in European media and communication research

(Excerto) The European Journal of Communication seeks to present the best in current research in the broad field of media and communication research. Irregularly, we seek to take stock by inviting a small group of leading scholars to present their work at a symposium on a common theme, which then forms the basis for a Special Issue of the Journal. In 2014, the European Science Foundation (ESF) published one of their ‘Forward Looks’ entitled Media in Europe: New Questions for Research and Policy. We subsequently invited several of the Forward Look’s authors to meet and discuss their work with us at a symposium hosted by the European University Cyprus, and the discussion and revised papers that resulted are published here.
