Co-circulação dos vírus dengue tipo 1, 2 e 4 nos Estados do Rio Grande do Norte e Paraíba, 2013

Dengue is a viral disease transmitted by female mosquitoes from genus Aedes, the principal urban vector is Aedes aegypti. Actually dengue has caused, in global scale, substantial morbidity and mortality. Four serotypes (antigenically distinct) are known: DENV-1, DENV-2, DENV-3 and DENV-4. The objective of this study was described the epidemiological profile dengue in the states of Rio Grande do Norte (RN) and Paraíba (PB), 2013. For that, suspected cases of dengue were studied, received for Laboratory of Molecular Biology of infectious disease and cancer (LADIC-UFRN) from different Health Units from RN and PB between January and December of 2013. The viral RNA was obtained from serum samples of patient from health units from RN and PB. It were studied 478 suspected cases of dengue , 252 (52,7%) from Rio Grande do Norte and 226 (47,3%) from Paraíba, showeds a global rate of infection global prevalence of 29,7% (142/478). The co-circulation of three serotypes was observed: DENV-1 (9,8% [14/142]), DENV-2 (3,5% [5/142]) and DENV-4 (86,7% [123/142]). People between 21-30 years old were the most affected by the disease during all the period of the study, representing 63,7% of the cases in both states. The genus most affected was female, representing 63,3% of cases in both states. Pau dos Ferros, Rio Grande do Norte, had the highest circulation of disease, with 8,2% (8/97) of cases. In Paraíba, the city most affected was João Pessoa, with (80% (36/45) of cases. The months with the biggest viral circulation in RN and PB were March and August, respectively. These results are very important to understanding the dengue viral activity in RN and PB, providing data that can guide control actions of this disease in support to local control programs

An examination of the role of the sports and exercise medicine specialist in Ireland- from epidemiology to treatment

The expansion of the specialty of sports and exercise medicine (SEM) is a relatively recent development in the medical community and the role of the SEM specialist continues to evolve and develop. The SEM specialist is ideally placed to care for all aspects of physical activity not only in athletes but also in the general population. As an advocate for physical activity the SEM specialist plays a broad role in advising safe effective sports and recreation participation; screening for disease related to sports participation; examining and contributing to the evidence behind treatment strategies and evaluating any potential negative impact of sports injury prevention measures. In this thesis I will demonstrate the breadth of the role the Sports and Exercise Medicine Specialist from epidemiology to in-depth examination of treatment strategies. In Chapter 2, I examined the epidemiology of sports and recreation related injury (SRI) in Ireland, an area that has previously been poorly studied. We report on 3,172 SRI (14% of total presentations) presentations to the ED over 6 months. Paediatric patients (4-16 yrs) were over represented comprising 39.9% of all SRI presentation compared to 16% of total ED presentations and 18% of the general population. These injuries were serious (32% fractures) and though 49% of injuries occurred during organised competition/practice, 41.5% occurred during recreation-most often at home. In Chapter 3, I examined risk factors associated with hand injury in hurling. The previous chapter highlighted the importance of a firm evidence base underpinning treatment strategies. When measures to improve welfare are introduced not only must potential benefits be measured, so too must potential unwanted adverse outcomes. In this study I examined a cohort of adult hurlers who had presented to the ED with a hurling related injury in order to highlight the variables associated with hand injury in this population. I found the athletes who wore a helmet were far more likely (OR 3.15 95% CI (1.51-6.56) p= 0.002) to suffer a hand injury than athletes who did not. Very few of those interviewed (4.9%) used hand protection compared to 65% who used helmet and faceguard. The introduction of the helmet and faceguard in hurling has undeniably decreased the incidence of head and face injury in hurling. However in tandem with this intervention several observational studies have demonstrated an increase in the occurrence of hurling related hand injuries. This study highlights the importance of being cognisant of unanticipated or unintended consequences when implementing a new treatment or intervention. In Chapter 4, I examined the role of population screening as applied to sport and exercise. This is a controversial area –cardiac screening in the exercising population has been the subject of much debate. Specifically I define the prevalence of exercise induced bronchoconstriction (EIB) using a specifically designed sports specific field-testing protocol. In this study I found almost a third (29%) of a full international professional rugby squad had confirmed asthma or EIB, as compared with 12-15% of the general population. Despite regular medical screening, 5 ‘new’ untreated cases (12%) were elicited by the challenge test and in the group already on treatment for asthma/EIB; over 50% still displayed EIB. In Chapter 5, I examined the evidence supporting current treatment options for iliotibial band friction syndrome (ITBFS). The practice of sports medicine has traditionally been ‘eminence based’ rather than ‘evidence based’. This may be problematic as some of these practices are based upon flawed principles- for example the treatment of iliotibial band friction syndrome (ITBFS). In this chapter, using cadaveric and biomechanical studies I expand upon the growing base of evidence clarifying the anatomy and biomechanics of the area-thereby re-examining the principles on which current treatments are based. The role of the SEM specialist is broad; we chose to examine specific examples of some of the roles that they execute. An understanding of the epidemiology of SRI presenting to the ED has implications for individual patients, sports governing bodies and health resource utilisation. Population screening is an important tool in health promotion and disease prevention in the general population. Screening in SEM may have similar less well-recognised benefits. The SEM specialist needs to be conversant in screening for medical conditions concerning physical activity. A comprehensive understanding of the pathophysiology of a disease is required for its diagnosis and treatment. Due to the ongoing evolution of SEM many treatments are eminence-based rather than evidence‐based practice. Continued re-examination of the fundamentals of current practice is essential. An awareness of potential unwanted side effects is essential prior to the introduction of any new treatment or intervention. The SEM specialist is ideally placed to advise sports governing bodies on these issues prior to and during their implementation.

To what extent has research conducted by the GaWC Research Network aided our understanding of large EU law firm geography?

This thesis explores whether a specific group of large EU law firms exhibited multiple common behaviours regarding their EU geographies between 1998 and 2009. These potentially common behaviours included their preferences for trading in certain EU locations, their usage of law firm alliances, and the specific reasons why they opened or closed EU branch offices. If my hypothesis is confirmed, this may indicate that certain aspects of large law firm geography are predictable – a finding potentially of interest to various stakeholders globally, including legal regulators, academics and law firms. In testing my hypothesis, I have drawn on research conducted by the Globalization and World Cities (GaWC) Research Network to assist me. Between 1999 and 2010, the GaWC published seven research papers exploring the geographies of large US and UK law firms. Several of the GaWC’s observations arising from these studies were evidence-based; others were speculative – including a novel approach for explaining legal practice branch office change, not adopted in research conducted previously or subsequently. By distilling the GaWC’s key observations these papers into a series of “sub-hypotheses”, I been able to test whether the geographical behaviours of my novel cohort of large EU law firms reflect those suggested by the GaWC. The more the GaWC’s suggested behaviours are observed among my cohort, the more my hypothesis will be supported. In conducting this exercise, I will additionally evaluate the extent to which the GaWC’s research has aided our understanding of large EU law firm geography. Ultimately, my findings broadly support most of the GaWC’s observations, notwithstanding our cohort differences and the speculative nature of several of the GaWC’s propositions. My investigation has also allowed me to refine several of the GaWC’s observations regarding commonly-observable large law firm geographical behaviours, while also addressing a key omission from the group’s research output.

Rethinking Care Through Social Reproduction: Articulating Circuits of Migration

Care has come to dominate much feminist research on globalized migrations and the transfer of labor from the South to the North, while the older concept of reproduction had been pushed into the background but is now becoming the subject of debates on the commodification of care in the household and changes in welfare state policies. This article argues that we could achieve a better understanding of the different modalities and trajectories of care in the reproduction of individuals, families, and communities, both of migrant and nonmigrant populations by articulating the diverse circuits of migration, in particular that of labor and the family. In doing this, I go back to the earlier North American writing on racialized minorities and migrants and stratified social reproduction. I also explore insights from current Asian studies of gendered circuits of migration connecting labor and marriage migrations as well as the notion of global householding that highlights the gender politics of social reproduction operating within and beyond households in institutional and welfare architectures. In contrast to Asia, there has relatively been little exploration in European studies of the articulation of labor and family migrations through the lens of social reproduction. However, connecting the different types of migration enables us to achieve a more complex understanding of care trajectories and their contribution to social reproduction.

Migrant domestic workers, vulnerability and the law: immigration and employment laws in Cyprus and Spain

The intersection of gender, welfare and immigration regimes has been one of the main focus of a rich scholarship on paid domestic work in Europe. This article brings into the discussion the nexus of employment and immigration law regimes to reflect on the role of legal regulation in structuring and reducing the vulnerability of domestic workers. I analyse this nexus by looking at the cases of Cyprus and Spain, two states falling under the cluster of Southern Mediterranean welfare regimes, that share certain characteristics in terms of immigration regimes, but have substantially different employment law regulation models. The first part sketches the debate on the employment law regulation of domestic work. The second part starts by giving an overview of the immigration regimes of Cyprus and Spain in relation to migrant domestic workers and then proceeds to analyse the two countries’ models and substance of employment law regulation in domestic work. The comparison of these two divergent approaches informs the debate on how the legal regulation of domestic work should be best structured. In Spain there have been recent dynamic legislative changes in the employment law regulation of domestic work. The final part of the article traces these changes and reflects on why such processes have not taken place in Cyprus.

Quand la manifestation tourne à l'émeute : les affrontements violents entre forces de l'ordre et manifestants en Côte d'Ivoire.

Les manifestations de crise, en Côte d'Ivoire, ont été extrêmement violentes. Au cours des quinze dernières années, plus de 400 personnes sont mortes, tuées dans des affrontements avec les forces de sécurités ou des contre-manifestants. Malgré la gravité du problème, peu d’études scientifiques y sont consacrées et les rares analyses et enquêtes existantes portent, de façon unilatérale, sur l’identité et la responsabilité pénale des auteurs et commanditaires putatifs de cette violence. La présente étude s’élève contre le moralisme inhérent à ces approches pour aborder la question sous l’angle de l’interaction : cette thèse a pour objectif de comprendre les processus et logiques qui sous-tendent l’usage de la violence au cours des manifestations. Le cadre théorique utilisé dans cette étude qualitative est l’interactionnisme symbolique. Le matériel d’analyse est composé d’entrevues et de divers documents. Trente-trois (33) entrevues semi-dirigées ont été réalisées avec des policiers et des manifestants, cooptés selon la technique de la boule de neige, entre le 3 janvier et le 15 mai 2013, à Abidjan. Les rapports d’enquête, de l’ONG Human Rights Watch, sur les manifestations de crise, les manuels de formation de la police et divers autres matériaux périphériques ont également été consultés. Les données ont été analysées suivant les principes et techniques de la théorisation ancrée (Paillée, 1994). Trois principaux résultats ont été obtenus. Premièrement, le système ivoirien de maintien de l'ordre est conçu selon le modèle d’une « police du prince ». Les forces de sécurité dans leur ensemble y occupent une fonction subalterne d’exécutant. Elles sont placées sous autorité politique avec pour mandat la défense inconditionnelle des institutions. Le style standard de gestion des foules, qui en découle, est légaliste et répressif, correspondant au style d’escalade de la force (McPhail, Schweingruber, & Carthy, 1998). Cette « police du prince » dispose toutefois de marges de manœuvre sur le terrain, qui lui permettent de moduler son style en fonction de la conception qu’elle se fait de l’attitude des manifestants : paternaliste avec les foules dites calmes, elle devient répressive ou déviante avec les foules qu’elle définit comme étant hostiles. Deuxièmement, à rebours d’une conception victimaire de la foule, la violence est une transaction situationnelle dynamique entre forces de sécurité et manifestants. La violence suit un processus ascendant dont les séquences et les règles d’enchainement sont décrites. Ainsi, le premier niveau auquel s’arrête la majorité des manifestations est celui d’une force non létale bilatérale dans lequel les deux acteurs, protestataires et policiers, ont recours à des armes non incapacitantes, où les cailloux des premiers répondent au gaz lacrymogène des seconds. Le deuxième niveau correspond à la létalité unilatérale : la police ouvre le feu lorsque les manifestants se rapprochent de trop près. Le troisième et dernier niveau est atteint lorsque les manifestants utilisent à leur tour des armes à feu, la létalité est alors bilatérale. Troisièmement, enfin, le concept de « l’indignité républicaine » rend compte de la logique de la violence dans les manifestations. La violence se déclenche et s’intensifie lorsqu’une des parties, manifestants ou policiers, interprète l’acte posé par l’adversaire comme étant en rupture avec le rôle attendu du statut qu’il revendique dans la manifestation. Cet acte jugé indigne a pour conséquence de le priver de la déférence rattachée à son statut et de justifier à son encontre l’usage de la force. Ces actes d’indignités, du point de vue des policiers, sont symbolisés par la figure du manifestant hostile. Pour les manifestants, l’indignité des forces de sécurité se reconnait par des actes qui les assimilent à une milice privée. Le degré d’indignité perçu de l’acte explique le niveau d’allocation de la violence.

Effect of sildenafil in renal ischemia/reperfusion injury in rats

To evaluate the effect of sildenafil, administered prior to renal ischemia/reperfusion (I/R), by scintigraphy and histopathological evaluation in rats. Methods: Twenty-four rats were divided randomly into two groups. They received 0.1 ml of 99mTechnetium-etilenodicisteine intravenous, and a baseline (initial) renal scintigraphy was performed. The rats underwent 60 minutes of ischemia by left renal artery clamping. The right kidney was not manipulated. The sildenafil group (n=12) received orally 1 mg/kg of sildenafil suspension 60 minutes before ischemia. Treatment with saline 0.9% in the control group (n=12). Half of the rats was assessed after 24 hours and half after seven days I/R, with new renal scintigraphy to study differential function. After euthanasia, kidneys were removed and subjected to histopathological examination. For statistical evaluation, Student t and Mann-Whitney tests were used. Results: In the control group rats, the left kidneys had significant functional deficit, seven days after I/R, whose scintigraphic pattern was consistent with acute tubular necrosis, compared with the initial scintigraphy (p<0.05). Sildenafil treatment resulted in better differential function of the left kidneys 24h after reperfusion, compared with controls. Histopathologically, the left kidney of control rats (24 hours after I/R) showed a higher degree of cellular necrosis when compared with the sildenafil treated rats (p<0.05). Conclusion: Sildenafil had a protective effect in rat kidneys subjected to normothermic I/R, demonstrated by scintigraphy and histomorphometry

Capital 2.0 capital formation and legal risk in a new global economic order from fiat to exit: including case studies of the proposed transatlantic trade and investment partnership between the United States and the European Union and the financing relation between the United States and the People’s Republic of China

Following the intrinsically linked balance sheets in his Capital Formation Life Cycle, Lukas M. Stahl explains with his Triple A Model of Accounting, Allocation and Accountability the stages of the Capital Formation process from FIAT to EXIT. Based on the theoretical foundations of legal risk laid by the International Bar Association with the help of Roger McCormick and legal scholars such as Joanna Benjamin, Matthew Whalley and Tobias Mahler, and founded on the basis of Wesley Hohfeld’s category theory of jural relations, Stahl develops his mutually exclusive Four Determinants of Legal Risk of Law, Lack of Right, Liability and Limitation. Those Four Determinants of Legal Risk allow us to apply, assess, and precisely describe the respective legal risk at all stages of the Capital Formation Life Cycle as demonstrated in case studies of nine industry verticals of the proposed and currently negotiated Transatlantic Trade and Investment Partnership between the United States of America and the European Union, TTIP, as well as in the case of the often cited financing relation between the United States and the People’s Republic of China. Having established the Four Determinants of Legal Risk and its application to the Capital Formation Life Cycle, Stahl then explores the theoretical foundations of capital formation, their historical basis in classical and neo-classical economics and its forefathers such as The Austrians around Eugen von Boehm-Bawerk, Ludwig von Mises and Friedrich von Hayek and most notably and controversial, Karl Marx, and their impact on today’s exponential expansion of capital formation. Starting off with the first pillar of his Triple A Model, Accounting, Stahl then moves on to explain the Three Factors of Capital Formation, Man, Machines and Money and shows how “value-added” is created with respect to the non-monetary capital factors of human resources and industrial production. Followed by a detailed analysis discussing the roles of the Three Actors of Monetary Capital Formation, Central Banks, Commercial Banks and Citizens Stahl readily dismisses a number of myths regarding the creation of money providing in-depth insight into the workings of monetary policy makers, their institutions and ultimate beneficiaries, the corporate and consumer citizens. In his second pillar, Allocation, Stahl continues his analysis of the balance sheets of the Capital Formation Life Cycle by discussing the role of The Five Key Accounts of Monetary Capital Formation, the Sovereign, Financial, Corporate, Private and International account of Monetary Capital Formation and the associated legal risks in the allocation of capital pursuant to his Four Determinants of Legal Risk. In his third pillar, Accountability, Stahl discusses the ever recurring Crisis-Reaction-Acceleration-Sequence-History, in short: CRASH, since the beginning of the millennium starting with the dot-com crash at the turn of the millennium, followed seven years later by the financial crisis of 2008 and the dislocations in the global economy we are facing another seven years later today in 2015 with several sordid debt restructurings under way and hundred thousands of refugees on the way caused by war and increasing inequality. Together with the regulatory reactions they have caused in the form of so-called landmark legislation such as the Sarbanes-Oxley Act of 2002, the Dodd-Frank Act of 2010, the JOBS Act of 2012 or the introduction of the Basel Accords, Basel II in 2004 and III in 2010, the European Financial Stability Facility of 2010, the European Stability Mechanism of 2012 and the European Banking Union of 2013, Stahl analyses the acceleration in size and scope of crises that appears to find often seemingly helpless bureaucratic responses, the inherent legal risks and the complete lack of accountability on part of those responsible. Stahl argues that the order of the day requires to address the root cause of the problems in the form of two fundamental design defects of our Global Economic Order, namely our monetary and judicial order. Inspired by a 1933 plan of nine University of Chicago economists abolishing the fractional reserve system, he proposes the introduction of Sovereign Money as a prerequisite to void misallocations by way of judicial order in the course of domestic and transnational insolvency proceedings including the restructuring of sovereign debt throughout the entire monetary system back to its origin without causing domino effects of banking collapses and failed financial institutions. In recognizing Austrian-American economist Schumpeter’s Concept of Creative Destruction, as a process of industrial mutation that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one, Stahl responds to Schumpeter’s economic chemotherapy with his Concept of Equitable Default mimicking an immunotherapy that strengthens the corpus economicus own immune system by providing for the judicial authority to terminate precisely those misallocations that have proven malignant causing default perusing the century old common law concept of equity that allows for the equitable reformation, rescission or restitution of contract by way of judicial order. Following a review of the proposed mechanisms of transnational dispute resolution and current court systems with transnational jurisdiction, Stahl advocates as a first step in order to complete the Capital Formation Life Cycle from FIAT, the creation of money by way of credit, to EXIT, the termination of money by way of judicial order, the institution of a Transatlantic Trade and Investment Court constituted by a panel of judges from the U.S. Court of International Trade and the European Court of Justice by following the model of the EFTA Court of the European Free Trade Association. Since the first time his proposal has been made public in June of 2014 after being discussed in academic circles since 2011, his or similar proposals have found numerous public supporters. Most notably, the former Vice President of the European Parliament, David Martin, has tabled an amendment in June 2015 in the course of the negotiations on TTIP calling for an independent judicial body and the Member of the European Commission, Cecilia Malmström, has presented her proposal of an International Investment Court on September 16, 2015. Stahl concludes, that for the first time in the history of our generation it appears that there is a real opportunity for reform of our Global Economic Order by curing the two fundamental design defects of our monetary order and judicial order with the abolition of the fractional reserve system and the introduction of Sovereign Money and the institution of a democratically elected Transatlantic Trade and Investment Court that commensurate with its jurisdiction extending to cases concerning the Transatlantic Trade and Investment Partnership may complete the Capital Formation Life Cycle resolving cases of default with the transnational judicial authority for terminal resolution of misallocations in a New Global Economic Order without the ensuing dangers of systemic collapse from FIAT to EXIT.

Review of the flood risk management system in Germany after the major flood in 2013

Widespread flooding in June 2013 caused damage costs of €6 to 8 billion in Germany, and awoke many memories of the floods in August 2002, which resulted in total damage of €11.6 billion and hence was the most expensive natural hazard event in Germany up to now. The event of 2002 does, however, also mark a reorientation toward an integrated flood risk management system in Germany. Therefore, the flood of 2013 offered the opportunity to review how the measures that politics, administration, and civil society have implemented since 2002 helped to cope with the flood and what still needs to be done to achieve effective and more integrated flood risk management. The review highlights considerable improvements on many levels, in particular (1) an increased consideration of flood hazards in spatial planning and urban development, (2) comprehensive property-level mitigation and preparedness measures, (3) more effective flood warnings and improved coordination of disaster response, and (4) a more targeted maintenance of flood defense systems. In 2013, this led to more effective flood management and to a reduction of damage. Nevertheless, important aspects remain unclear and need to be clarified. This particularly holds for balanced and coordinated strategies for reducing and overcoming the impacts of flooding in large catchments, cross-border and interdisciplinary cooperation, the role of the general public in the different phases of flood risk management, as well as a transparent risk transfer system. Recurring flood events reveal that flood risk management is a continuous task. Hence, risk drivers, such as climate change, land-use changes, economic developments, or demographic change and the resultant risks must be investigated at regular intervals, and risk reduction strategies and processes must be reassessed as well as adapted and implemented in a dialogue with all stakeholders.

Utilização do “cheque-dentista” por parte de crianças de 10 e 13 anos no ano letivo 2013/2014 em duas escolas no agrupamento de Vizela

Introdução: Uma grande parte de todas as consultas de medicina dentária realizadas em Portugal ocorre em prestadores de natureza privada, consequentemente a acessibilidade, principalmente entre os estatutos socioeconomicamente mais desfavorecido é dificultada. As crianças e os jovens são um grupo especial da população que necessita de particular atenção e proteção por parte dos serviços governamentais, investir na sua saúde e no seu bem‐estar garante ganhos de saúde ao longo das suas vidas. Tendo isto em conta, foi criado o Programa Nacional de Promoção de Saúde Oral (PNPSO). Os objetivos principais deste programa consistem na redução da incidência de doenças orais, melhoria dos conhecimentos e comportamentos sobre saúde oral e a promoção da equidade na prestação de cuidados de saúde oral. Desta forma são emitidos cheques-dentista para determinados grupos populacionais, sendo eles crianças e jovens com idade inferior a 16 anos, gravidas a ser seguidas no SNS, beneficiários do complemento solidário para idosos, portadores de Sida/VIH, e consultas no âmbito da prevenção do cancro oral. Participantes e Métodos: Realizou-se um estudo observacional transversal onde a população em análise foi constituída pelos responsáveis dos alunos de 10 e 13 anos abrangidos pelo PNPSO que no ano letivo 2013/2014 frequentaram o Colégio de Vizela e o Instituto Silva Monteiro. A recolha de dados foi feita através de um inquérito realizado por escrito com questões relativas à utilização dos documentos no âmbito do PNPSO. Em ambas as situações esteve presente o consentimento informado e garantiu-se a total confidencialidade dos dados. Os dados recolhidos neste estudo foram submetidos a uma análise estatística recorrendo ao software IBM SPSS Statistics v22. Resultados: Na população analisada quando questionados “O seu educando já tinha tido alguma consulta de medicina dentária?” 88,5% responderam “sim”, desses a maioria referiu que o médico dentista onde essas consultas foram realizadas estava incluído no programa (81,5%). Uma grande parte dos inquiridos referiu a escola como fator que lhes deu a conhecer o programa (sendo que 90,2% incluíram essa opção nas suas respostas). Quando questionados se fizeram tratamentos fora do programa 54,9% responderam que não. Em relação à utilização do(s) cheque(s)-dentista a que tiveram direito, 86,1% dos beneficiários referiu ter utilizado, desses, 67,6% mencionou a conclusão dos tratamentos com as consultas no âmbito do programa. Quando questionados o que os levou a escolher o consultório onde os tratamentos incluídos no PNPSO foram realizados, 57,9% do total de respostas foram para o “conhecimento prévio do médico dentista”. Na opinião de grande parte dos inquiridos (97,5%), o cheque-dentista é um incentivo para cuidados de saúde oral. No futuro, 99,2% dos beneficiários referiram que irão realizar os tratamentos a que tenham direito com o PNPSO. Conclusão: Com este estudo foi possível observar que grande parte dos beneficiários analisados utilizou o(s) cheque(s)-dentista a que tiveram direito. É possível observar que a maioria dos utentes referiram ter beneficiado com o programa, e afirmam que este constitui um meio de promoção e prevenção de doenças orais futuras e um incentivo para os cuidados de saúde oral. O processo de divulgação do PNPSO foi na sua maioria realizado pelas escolas, em que ambas se revelaram competentes a dar a conhecer o programa aos beneficiários.

Channel-forming activity of syringopeptin 25 A in mercury-supported phospholipid monolayers and negatively charged bilayers

Interactions of the cationic lipodepsipeptide syringopeptin 25 A (SP25A) with mercury-supported dioleoylphosphatidylcholine (DOPC), dioleoylphosphatidylserine (DOPS) and dioeleoylphosphatidic acid (DOPA) self-assembled monolayers (SAMs) were investigated by AC voltammetry in 0.1 M KCl at pH 3, 5.4 and 6.8. SP25A targets and penetrates the DOPS SAM much more effectively than the other SAMs not only at pH 6.8, where the DOPS SAM is negatively charged, but also at pH 3, where it is positively charged just as SP25A. Similar investigations at tethered bilayer lipid membranes (tBLMs) consisting of a thiolipid called DPTL anchored to mercury, with a DOPS, DOPA or DOPC distal monolayer on top of it, showed that, at physiological transmembrane potentials, SP25A forms ion channels spanning the tBLM only if DOPS is the distal monolayer. The distinguishing chemical feature of the DOPS SAM is the ionic interaction between the protonated amino group of a DOPS molecule and the carboxylate group of an adjacent phospholipid molecule. Under the reasonable assumption that SP25A preferentially interacts with this ion pair, the selective lipodepsipeptide antimicrobial activity against Gram-positive bacteria may be tentatively explained by its affinity for similar protonated amino-carboxylate pairs, which are expected to be present in the peptide moieties of peptidoglycan strands.

Effects of a 12-week aerobic exercise intervention on eating behaviour, food cravings and 7-day energy intake and energy expenditure in inactive men

This study examined effects of 12 weeks of moderate-intensity aerobic exercise on eating behaviour, food cravings and weekly energy intake and expenditure in inactive men. Eleven healthy men (mean ± SD: age, 26 ± 5 years; body mass index, 24.6 ± 3.8 kg/m2; maximum oxygen uptake, 43.1 ± 7.4 mL/kg/min) completed the 12-week supervised exercise programme. Body composition, health markers (e.g. blood pressure), eating behaviour, food cravings and weekly energy intake and expenditure were assessed before and after the exercise intervention. There were no intervention effects on weekly free-living energy intake (p=0.326, d=-0.12) and expenditure (p=0.799, d=0.04), or uncontrolled eating and emotional eating scores (p>0.05). However, there was a trend with a medium effect size (p=0.058, d=0.68) for cognitive restraint to be greater after the exercise intervention. Total food cravings (p=0.009, d=-1.19) and specific cravings of high-fat foods (p=0.023, d=-0.90), fast-food fats (p=0.009, d=-0.71) and carbohydrates/starches (p=0.009, d=-0.56) decreased from baseline to 12 weeks. Moreover, there was a trend with a large effect size for cravings of sweets (p=0.052, d=-0.86) to be lower after the exercise intervention. In summary, 12 weeks of moderate-intensity aerobic exercise reduced food cravings and increased cognitive restraint, however, these were not accompanied by changes in other eating behaviours and weekly energy intake and expenditure. The results indicate the importance of exercising for health improvements even when reductions in body mass are modest.
