A ESCOLA NO QUINTAL DA CULTURA: TEATRALIDADES EM PERSPECTIVA DIALÓGICA
Authors: Gonçalves Jean Carlos
Published: September 2017

Esse artigo tem como objetivo compreender os sentidos de escola na série brasileira Quintal da Cultura, exibida pela TV Cultura. Escolheu-se como corpus o episódio A Escolinha do Quintal – Vogais. A análise é realizada a partir dos pressupostos da perspectiva dialógica que tem nos estudos de Bakhtin e o Círculo sua ancoragem teórica. Os resultados do trabalho apontam para a relação com o discurso teatral e com efeitos de teatralidade como fatores intrínsecos ao programa em questão. Em contraponto, a análise dos dados apresenta sentidos de escola bastante provocadores do ponto de vista da noção bakhtiniana de relações dialógicas, principalmente no que se refere à visualidade cenográfica do espaço da sala de aula e à presença de relações de poder e forças entre professores e alunos. A série revisita a escola por meio de códigos e signos de um projeto discursivo ainda marcado pela resistência à mudança e às reconfigurações educacionais da contemporaneidade.
CURRÍCULO INTEGRADO, ENSINO MÉDIO TÉCNICO E BASE NACIONAL COMUM CURRICULAR: ENTREVISTA COM GAUDÊNCIO FRIGOTTO
Authors: Frigotto Gaudêncio , Dickmann Ivo , Pertuzatti Ieda
Published: September 2017

O professor Gaudêncio Frigotto, da Universidade do Estado do Rio de Janeiro e da Universidade Federal Fluminense, é um dos mais eminentes educadores da atualidade brasileira e latino-americana. Seus estudos sobre a relação educação e trabalho são referência no campo da educação básica e das políticas de currículo. Esta entrevista, realizada em Chapecó-SC, discute as questões curriculares mais atuais da educação brasileira: o ensino médio técnico e integral e a Base Nacional Comum Curricular (BNCC). Seu discurso reforça suas posições sobre a responsabilidade da escola pública de construir um ser humano omnilateral, via currículo integrado e integral e apresenta sua crítica sobre o processo de construção da BNCC, que se faz às avessas por ser eminentemente conservador, restritivo e penalizador à escola pública em detrimento da escola privada. Por fim, em tom profético, ao analisar o cenário educativo brasileiro pós-golpe parlamentar à democracia, o professor Frigotto anuncia as intempéries que viriam a se concretizar com a reforma do ensino médio via medida provisória 746/2016 e a PEC 241/2016.
A (in) estabilidade dos usos do corpo: sobre as práticas de prevenção em saúde e segurança do trabalho no contexto de uma companhia geradora de energia elétrica no nordeste brasileiro
Authors: Monteiro Fabiana Ribeiro , Furtado Odair
Published: September 2017

O objetivo geral deste estudo consistiu em compreender a atividade dos profissionais da saúde e segurança do trabalho numa empresa geradora de energia elétrica no nordeste brasileiro. A partir desta experiência, desenvolvemos uma linha de análise sobre como esta práxis laboral prevencionista ilustra a constituição da produção/manutenção do corpo-máquina na atualidade capitalista. Foi possível verificar entre os participantes da pesquisa, dentre outros aspectos, um imenso esforço para cumprir as exigências normativas da legislação, fato que se materializava na metodologia de trabalho adotada e recomendada por esses trabalhadores, como a execução de campanhas educativas, palestras, treinamentos, auditorias, cujo discurso pautava-se, de forma geral, no uso adequado do corpo para evitar doenças e acidentes ocupacionais. Campo de captura da subjetividade do capital, o corpo individual está associado às práticas mais concretas do cotidiano e ilustra que existe uma história de aproximação privada do eu, assim como há uma história da propriedade de produção.

THE INEXORABLE RISE OF THE NEW INTERVENTIONISM
Authors: ALBESCU Oana , MANIU Mircea
Published: September 2017

The present research follows two different movements: what happens and the way we think about what actually happens in terms of global political and economic governance. The first is a realistic approach considering the recent developments throughout the world, the second is an idealistic approach of ideologies attempting to change reality - but nevertheless influenced by the very reality they aspire to model. Towards the end we try to articulate these two tracks: 1. In terms of ideology, we believe we are witnessing today a sharp decline in ideological rigor. Contrasted to the Second World War fanatical clash of ideologies, or with the rigid dogmatism of the Cold War, we cannot help noticing that we live somehow phlegmatic times. Ideologies do exist, but there is a hegemonic centrist, gray tendency, put between the clearly understandable black and white. 2. In terms of politics and economics, the real world is heading on different ways. Both Russia and China have enforced heterodox interventionist policies. But even US acted ad hoc during the financial crisis. And the same might be said about EU during the migration crisis. Our point is that the rise of the new interventionism goes hand in hand with the recent softening of ideological constraints. In our closing chapter we argue that the ideological vacuum behind the new interventionism has been filled mostly by either technocratic or/and ad hoc-ratic attitudes.
THE IDEOLOGY OF ECONOMIC LIBERALISM AND THE POLITICS OF HOUSING IN ROMANIA
Authors: VINCZE Enikő
Published: September 2017

The privatization of housing (linked to the privatization of means of production), respectively the creation of a new private housing fund, have been crucial for the emergence of capitalist property regime and market economy in Romania. The state withdrew from its position as a developer (of housing stock, but not only), however it did not remain passive, contrary, it assumed a central role in the creation of the (housing) market through modifying legislation and creating new institutions that administered this process. The article is addressing how the ideology of economic liberalism is working through housing politics as a core medium of the transformation of really existing socialism into neoliberal capitalism. In particular, it describes how – through privatization – this ideology creates material effects in the housing sector, i.e. accumulation on the one side and dispossession on the other side of the class structure. Moreover, the article insists that the housing stock’s privatization after 1990 happened in relation with the housing politics of state socialism, which allowed the existence of three types of property on housing. The creation of a new private housing fund was tied to post-socialist primitive accumulation resulted from the privatization of state enterprises and from the investment of profit obtained in the due process into real estate businesses. After some introductory ideas about ideologies and housing politics, the article discusses the privatization of housing and the creation of the private housing stock as central pillars of capitalist political economy. The description of some features of housing production and personal ownership of dwellings in state socialism is followed by an account on the promotion of privatization after 1990 by local-national-transnational actors using the example of the city of Cluj. The last chapter of the article concludes on the process of transformation of state socialism into neoliberal capitalism through the politics of housing sustained by the ideology of economic liberalism.
QU’EST-CE QUE LE NÉO-POPULISME? QUELQUES EXPLIQUATIONS FACTUELLES POUR UN ÉCLAIRCISSEMENT THÉORIQUE
Authors: MIȘCOIU Sergiu
Published: September 2017

What is Neo-Populism? Factual Contributions for Theoretical Advancements. In defining the specificity of neo-populism, numerous theoretical attempts have been leading to rather unsatisfactory results. In this article, instead of trying to abstractly define neo-populism, by using a wide range of examples, I will propose a series of empirical delineations that will contribute to a theoretical clarification of the specificity of neo-populism in relation to its mother-concept – populism.
POPULISM AND LEADERSHIP: IS THERE ANYTHING NEW UNDER THE SUN?
Authors: SOARE Sorina
Published: September 2017

The literature on populism tends to consider dominant leaders as a characteristic feature of populist parties across time and space. However, we know very little about what the populist leadership is about. In this context, this article aims to contribute to a relatively unexplored arena of populist studies, which is what is special about the populist political leadership in an increasingly personalised politics. In the attempt to bridge the literature on populism and personalization of politics, the article argues that populist leadership mirrors the nucleus of the populist discourse. The centrality of the party leader translates in most cases into the emphasis on the unmediated, hence un-institutionalized, genuine democracy that populist parties tend to preach. Because of the veneration of the people, populist leadership is not primarily about communicational skill and (technical) competence but also – first and foremost – a continuously demonstrated trust. Hence the populist leadership is about the mutual pursuit of the people’s interests. Populist leaders must demonstrate by both word and personal example that they are from the people, like the people.
RADICALISM AND MODERNITY
Authors: RAKUSA-SUSZCZEWSKI Mikołaj
Published: September 2017

In contemporary debates on social radicalism there is a predominant belief that it carries with it serious threats to the public sphere, similar to all manifestations of extremism and other attitudes that challenge and question the liberal basis of the social order. The persistent and almost obsessive identification of radicalism with populism and religious fundamentalism, and in general with danger to the social order, seems to confirm this tendency. Meanwhile, the alternative subject literature indicates how much this way of thinking is ideologized and aligned with conservatism in thought, casting a blind eye to the complex motives of the radical subject. We refer here to various applications of radicalism as a philosophical, psychological and social predicament, which prompts the revision of abusive and simplified interpretations. We also assume that radicalism, as properly understood, can be interpreted as a kind of peculiar fever emerging out of the piling up of possibilities brought about by modernity. Radicalism is a disquieting state of mind, which appears not so strongly in a risk society as in a society of infinite opportunities.
HOW TO LOOK AT NEOLIBERALISM. REVISITING ADORNO'S SOCIAL PHYSIOGNOMY
Authors: BOGDAN Ciprian
Published: September 2017

Against the widespread view that Adorno remains stuck in an antiquated way of approaching ideology as expression of social totality, the present article tries to recuperate Adorno’s dialectical legacy in the context of contemporary neoliberalism. One central point made by Adorno - though usually missed by interpreters - is that ideology operates according to the Hegelian “negation of negation”. We believe that this basic insight can be applied not only to liberal capitalism (19th century) and monopoly capitalism (20th century), but also to neoliberalism, thus shedding a new light even on contemporary phenomena like fake news or the proliferation of dystopian political scenarios as in the case of Trump or Brexit campaigns.
IDEOLOGICAL CONSTRUCTIONS AND SOCIOLOGICAL (MIS)UNDERSTANDINGS IN INTERNATIONAL RELATIONS. THE CASE OF ‘TRANSATLANTIC COMMUNITY’
Authors: VĂETIȘI Șerban
Published: September 2017

The article investigates the various formulas and constructions expressing and contributing to the evolution of Transatlantic community as regional transcontinental set of relationships; political and discursive construction of shared principles, values, and strategies; and social/sociological reality. The suggested analysis provides a critical reappraisal of some of its fundamental elements of definition, ideology, political structure and social-historical complexity, while attempting to contrast between the systemic and intrasystemic views of community. The interpretation reveals the necessity to ask ourselves whether there exist something like a Transatlantic community that can be defined in sociological sense, and, secondly, to question the uses and limits of a sociology of international relations as sociology of transatlantic community. The article concludes on some mutations at the level of sociological epistemology, that would ultimately reposition a legitimate focus on Transatlantic community, beyond its critical histories, supra-political reality, restrictive policies, and Manichaean ideology.
THE EUROPEAN UNION AND CHINA: ON THE CHALLENGES OF THE STRATEGIC PARTNERSHIP
Authors: PANTEA Ana
Published: September 2017

China and the EU are both skilful and pragmatic powers which shape their foreign policies in different manners, according to their principles. In the case of PRC, we can notice primordially domestic priorities like the need to sustain economic growth and to cover political legitimacy. In recent years, its foreign policy has been challenged by the need to manage the consequences of its own success, which have come as a response of new demands for securing global stability. The EU strategy states that the engagement with China will be “principled, practical and pragmatic”, staying true to its interests and values. As such, the present article discusses the challenges of EU-China partnership as it has to respond to the interferences of national, European and global interests.

EL DESCUBRIMIENTO DE LOS FENÓMENOS METEOROLÓGICOS EN EDUCACIÓN INFANTIL. UNA PROPUESTA EXPERIMENTAL
Authors: De Álvaro Marciel Patricia
Published: September 2017

El presente artículo recoge un proyecto educativo orientado al conocimiento de los fenómenos meteorológicos en Educación Infantil, basado en la investigación, la manipulación y la experimentación por parte de los más pequeños, y centrado más en el gusto por aprender e investigar que en el simple hecho de adquirir conceptos de una forma meramente mecánica. Nuestra propuesta aborda tanto el descubrimiento de las características físicas del medio como el desarrollo afectivo, el movimiento, los hábitos de control corporal, la comunicación y las relaciones sociales, todo ello tratado desde una perspectiva científica que defiende la importancia de la ciencia y la experimentación en Educación Infantil. Para ello, recurrimos al trabajo por rincones, una estrategia educativa que se adapta a la perfección al aprendizaje científico que queremos trabajar en el aula.

Published: September 2017

This study was carried out to determine the glycemic index of coconut-enriched gari which was fermented at various durations. A total of 18 apparently healthy subjects participated in the study. The determination of total carbohydrate, crude fibre and available carbohydrate, followed by glycemic index was performed on six samples of the coconut gari using the standard operating procedure. The coconut gari samples (48 hours fermentation) gave mean glycemic index values ranging from 81.96 ± 3.42 - 84.96 ± 4.90 while the 72 hours fermentation gave a mean range of 74.34 ± 2.24 – 82.04 ±5.40. The samples were subjected to statistical analysis using ANOVA and found to be non-significantly (p > 0.05) different when compared to each other. The low G.I rating observed in coconut gari fermented for 72 hours is an indication that the food may be good for consumption as a staple except with under some exceptional conditions. This study suggests that extensive fermentation of gari enriched with coconut could be nutritionally appropriate for diabetics.

O dimensionamento das condutas deverá ter em consideração o número de condutores isolados ou cabos que poderão ser colocados nessa mesma conduta, tendo por base as suas características, o modo de instalação das canalizações e o diâmetro útil (interior) da própria conduta. Nas Regras Técnicas de Instalações Eléctricas de Baixa Tensão, com exceção, das instalações coletivas e entradas, não é definido um valor máximo de ocupação da secção reta interior das condutas pelos condutores isolados e cabos, sendo o único requisito a garantir, que as condutas permitam o fácil enfiamento e desenfiamento dos condutores isolados e cabos. No entanto, as mesmas regras recomendam uma ocupação da conduta não superior a um terço da sua secção reta interna, de forma a garantir, nomeadamente, o fácil enfiamento (e desenfiamento) dos condutores isolados e dos cabos.

Health care providers’ recommendations and influenza vaccination during pregnancy: A Québec survey
Authors: Desjardins Michaël , Paquet Caroline , Boucoiran Isabelle , Laferrière Céline , Gosselin-Brisson Anne , Labbé Annie-Claude , Martel-Laferrière Valérie
Published: September 2017

Background: Seasonal influenza is associated with high morbidity and mortality among pregnant women. Inactivated influenza vaccine is recommended for all pregnant women. Our study evaluated health care providers’ compliance with current Québec guidelines and their estimation of vaccine acceptance among the pregnant women they care for. Methods: An electronic survey was distributed to 1,084 health care providers, including general practitioners (GP), obstetrician-gynecologists (OBGYN), midwives, and nurse practitioners (NP), in Québec who followed at least one pregnant woman in the past year and who could be reached by their professional association by email. The survey was available online (via SurveyMonkey) between January 15 and February 15, 2015. Results: A total of 344/1,084 health care providers (32%) answered the survey: 134/250 GPs (54%), 91/497 OBGYNs (18%), 76/186 midwives (40%), and 43/150 NPs (29%). Overall, 60% of participants reported following current recommendations. Provider’s age <40 years old (54% versus 67%; p=0.02), low number of pregnancies followed per year (<50: 35% versus ≥50: 73%; p<0.001), and having a non-academic practice (54% vs 66%; p=0.03) were associated with lower compliance with guidelines. Compliance with vaccination recommendations differed between professions (OBGYNs: 80%, NPs: 72%, GPs: 67%, midwives: 12%; p<0.001). According to participants, about 40% of women accept vaccination when offered, and their reasons for refusing vaccination were mostly efficacy and safety issues. Conclusions: Québec faces major barriers to influenza vaccination of pregnant women: health care professionals report low compliance with guidelines, and they perceive and report that women are reluctant to accept vaccination. Action should be taken to increase vaccination offers by health care workers to pregnant women, with the aim of increasing the influenza immunization rate in this population.
Self-stool banking as a source for fecal microbiota transplantation: A pilot study
Authors: Raybardhan Sumit , Ng Wil , Tomassi Joanne , Katz Kevin
Published: September 2017

Background: Fecal microbiota transplantation is a promising therapeutic alternative for refractory Clostridium difficile infection. Self-stool donation can overcome challenges with donor screening and eliminate risks of blood borne pathogen exposure. We assessed the feasibility of a fecal banking protocol. A secondary objective was to identify perceptions around fecal banking. Methods: Admitted medicine patients were screened over 15 months. Patients with gastrointestinal comorbidities or factors affecting intestinal microbiota were excluded. Participants completed a survey and could opt to bank a sample. Processing occurred during defined lab hours. Feasibility was assessed on process and resource indicators. Success was defined as 50% consent rate. Results: A total of 4,675 patients were screened; 60% were excluded, primarily because of antibiotic exposure (1,343, 48%). A total of 537 patients were surveyed, of whom 73% consented to fecal banking. The primary reason for declining was that fecal banking was considered ‘too gross’ (34%). Of 72 samples provided, 27 were successfully banked. Lack of a bowel movement was the primary reason for not banking (54%), and inadequate quantity was the top reason for rejecting a collected sample (63%). Average processing time was 58 minutes (range 22–640 min). The majority of participants reported a preference for using their own stool (82%), and 87.5% (n=64) were willing to bank again. Conclusion: A self-donor fecal banking protocol is feasible. Scalability of this process is addressed through dedicated resources for collecting and processing samples from larger cohorts. Formal evaluation of the efficacy and microbiome integrity of samples is required.
Management of cytomegalovirus in hematopoietic stem cell transplant recipients: A review of novel pharmacologic and cellular therapies
Authors: Kronfli Nadine , Haider Shariq
Published: September 2017

Background: Despite diagnostic and therapeutic advances, cytomegalovirus (CMV) infection has remained a significant complication after hematopoietic stem cell transplantation (HSCT). The widespread use of pre-emptive antiviral therapy has reduced, but not eliminated, the occurrence of early CMV infection. The epidemiological shift of CMV infection, requiring repeated and prolonged treatment courses, creates an increasing need for novel antiviral drugs. This is an exciting time in the evolution of pharmacologic anti-CMV therapies. Objective: This review article provides an update on the therapeutic options for treatment of CMV in HSCT recipients, focusing on new pharmacologic agents—including maribavir, letermovir, brincidofovir, leflunomide, and artesunate—as well on as the emerging concept of cellular therapies and the future of a CMV vaccine. Results: In the past few years, encouraging preliminary data has emerged for both new pharmacologic therapies and cellular therapies; however, current evidence does not support their routine use for CMV prophylaxis or treatment. Conclusions: Despite the lack of data substantiating the routine use of new pharmacologic and cellular therapies, numerous trials, many of which are either phase III or randomized, are currently underway and will undoubtedly influence the use of these agents in the near future. CMV vaccines offer a safe and effective alternative to pharmacologic and cellular therapies as we await results of phase III clinical trials.
Successful use of intrathecal colistin in the treatment of Pseudomonas aeruginosa ventriculitis
Authors: Whellams Diana , Chagla Zain , Irfan Neal
Published: September 2017

This case report describes a 56-year-old woman with multi-drug-resistant Pseudomonas aeruginosa ventriculitis secondary to external ventricular drain insertion who was successfully treated with intrathecal colistin, intravenous colistin, and intravenous meropenem. A review of the English-language literature found six similar cases. While the patient did not experience side effects, self-limited paresthesias of the arm were noted in one case report. Intrathecal colistin should be considered as a therapy for ventriculitis when antibiotic choices are limited by resistant organisms. Patients should be monitored for neurological side effects during therapy.
Shunt freedom and clinical resolution of idiopathic intracranial hypertension after bariatric surgery in the pediatric population: report of 3 cases
Authors: Hoang Kimberly B. , Hooten Kristopher G. , Muh Carrie R.
Published: September 2017

Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a disease of elevated intracranial pressure that is thought to develop due to impaired CSF absorption related to elevated venous sinus pressure in the setting of increased intraabdominal and thoracic pressures. Symptoms can be disabling and, if left untreated, can lead to permanent visual loss. Previous treatments directed toward vision preservation include CSF diversion through shunting and optic nerve sheath fenestration. Recently, attention has been turned toward surgical weight loss strategies as an alternative to shunt treatment. The authors present a report of 3 patients with adolescent-onset IIH that was treated at the authors’ institution (Duke University) in whom bariatric surgery was pursued successfully. The patients had previously undergone CSF shunting at ages 12, 15, and 23 years. They were shunt dependent for a collective average of 3.3 years prior to bariatriwc surgery. All patients reported “low-pressure” or postural headaches after bariatric surgery that correlated with dramatic reduction in their weight. Two of the 3 patients had their shunts removed and continued to be shunt free 1.5 years later at last follow-up; the third patient remained shunt dependent with the pressure set at 200 mm H2O. Given the significant complications inherent to multiple shunt revisions, earlier intervention for weight loss, including bariatric surgery, in these patients might have prevented complications and the associated health care burden. The authors recommend a multidisciplinary approach for IIH treatment with early consideration for weight loss interventions in select patients.

Published: September 2017

High-altitude electromagnetic pulse can couple oil-gas pipeline systems to cause damage to electronic equipments. In order to study the effects of high-altitude electromagnetic pulse on buried pipeline, the differential equations for high-altitude electromagnetic pulse coupling buried pipeline are derived based on Maxwell’s equations. The coupling equations are solved in frequency domain, and then the induced current and voltage waveforms are obtained by using inverse Fourier transform. The currents and voltages at both ends and in the middle of pipeline are calculated. It is shown that the peak values of the currents along the pipeline don’t vary much. The voltages at both ends of the pipeline are larger and the voltage polarity at one end is opposite to another, while the voltages in the middle of the pipeline are smaller. Finally, the effects of system characteristics on induced currents are presented, such as the length of the pipeline, the depth of the pipeline, the radius of outer surface of the pipeline and the conductivity of the ground. The results of these studies are applicable to electromagnetic pulse protection.

Published: September 2017

The energy balance of internal combustion engines used in vehicles today shows that between 50 and 80% of the fuel energy is lost. This waste of energy has fostered a growing interest in energy harvesting systems in the automobile sector. This energy can be recovered, for example, from the cooling and exhaust systems, the brakes or the suspension system. With regard to suspension system harvesters, usually called Energy Harvesting Shock Absorbers (EHSAs), many solutions, based on different technologies, have been proposed so far in the literature available. Unfortunately, to date there is no commonly-accepted approach that allows the designers to select the best technology to replace a conventional damper with another component, i.e. an EHSA, which harvests energy but at the same time offers the same contribution to comfort and handling as the conventional damper. This paper presents a general methodology which can be used to compare present or future EHSA solutions. It studies the technology behind direct drive and electromechanical shock absorbers, and an electromechanical representation is proposed for each of them. Besides, for comparison purposes, a common equivalent mechanical representation for each EHSA is suggested. Some experimental results, using track-recorded data to estimate an urban road profile and also the ISO 8608 standard class C roughness index, are included, which demonstrate the ability of the methodology to compare effectively different EHSAs which harvest energy but at the same time have the damping characteristics of a conventional shock absorber.

Published: September 2017

The magnetic flux density in the magnetizing coil during the hysteresis measurement was calculated. The influence of a slot, machined in a ferromagnetic plate was simulated. The size of the magnetizing yoke was changed and the influence of this modification was studied on the detectable flux density. The size of the slot and the thickness of the air gap, which appears between the magnetizing yoke and plate’s surface, was also taken into account. It was found that by this simulation the experimental conditions could be successfully modelled. A sensitivity analysis of the studied nondestructive testing setup was also performed and the impact of different experimental parameters was analyzed. The results of simulation can be used successfully for determining the optimal parameters of the actual measurement arrangement if method Magnetic Adaptive Testing measuring technique (which is based on systematic measurement and evaluation of minor magnetic hysteresis loops) is applied.

Published: September 2017

Background:

Many studies are currently researching the effects of video games, particularly in the domain of cognitive training. Great variability exists among video games however, and few studies have attempted to compare different types of video games. Little is known, for instance, about the cognitive processes or brain structures that underlie learning of different genres of video games.

Objective:

To examine the cognitive and neural underpinnings of two different types of game learning in order to evaluate their common and separate correlates, with the hopes of informing future intervention research.

Methods:

Participants (31 younger adults and 31 older adults) completed an extensive cognitive battery and played two different genres of video games, one action game and one strategy game, for 1.5 hours each. DTI scans were acquired for each participant, and regional fractional anisotropy (FA) values were extracted using the JHU atlas.

Results:

Behavioral results indicated that better performance on tasks of working memory and perceptual discrimination was related to enhanced learning in both games, even after controlling for age, whereas better performance on a perceptual speed task was uniquely related with enhanced learning of the strategy game. DTI results indicated that white matter FA in the right fornix/stria terminalis was correlated with action game learning, whereas white matter FA in the left cingulum/hippocampus was correlated with strategy game learning, even after controlling for age.

Conclusion:

Although cognition, to a large extent, was a common predictor of both types of game learning, regional white matter FA could separately predict action and strategy game learning. Given the neural and cognitive correlates of strategy game learning, strategy games may provide a more beneficial training tool for adults suffering from memory-related disorders or declines in processing speed, particularly older adults.
Pulsed Thermography Applied to the Study of Cultural Heritage

Published: September 2017

In this paper, an overview of the recent applications of pulsed infrared thermography is presented. Pulsed infrared thermography, which provides stratigraphic information by analyzing the heat diffusion process within the sample after a thermal perturbation, is applied to the investigation of different kinds of cultural heritage artefacts. In particular, it is used to analyze repairs, decorative elements, and casting faults on bronzes, to detect texts hidden or damaged in ancient books/documents, and to characterize paint decorations. Moreover, the integration of pulsed infrared thermography and three-dimensional shape recording methods is proposed in order to provide a three-dimensional representation of the thermographic results. Finally, it is shown how the obtained thermographic results may be crucial from the historical and artistic points of view for understanding the modus operandi of a specific artist and/or of a workshop and for reconstructing the manufacturing process of the analyzed artefacts.
Coconut Allergy Revisited
Authors: Anagnostou Katherine
Published: September 2017

Despite concerns voiced often by food-allergic patients, allergy to coconut is rare, not directly associated with nut allergy and few cases are reported so far in the literature. We present an interesting case of coconut allergy in a child that was previously tolerant to coconut and regularly exposed via both the skin and gastrointestinal route.
Anacetrapib, a New CETP Inhibitor: The New Tool for the Management of Dyslipidemias?
Authors: Filippatos Theodosios D. , Kei Anastazia , Elisaf Moses S.
Published: September 2017

Cholesteryl ester transfer protein (CETP) inhibitors significantly increase serum high-density lipoprotein cholesterol (HDL) cholesterol levels and decrease low-density lipoprotein cholesterol (LDL) cholesterol concentration. However, three drugs of this class failed to show a decrease of cardiovascular events in high-risk patients. A new CETP inhibitor, anacetrapib, substantially increases HDL cholesterol and apolipoprotein (Apo) AI levels with a profound increase of large HDL2 particles, but also pre-β HDL particles, decreases LDL cholesterol levels mainly due to increased catabolism of LDL particles through LDL receptors, decreases lipoprotein a (Lp(a)) levels owing to a decreased Apo (a) production and, finally, decreases modestly triglyceride (TRG) levels due to increased lipolysis and increased receptor-mediated catabolism of TRG-rich particles. Interestingly, anacetrapib may be associated with a beneficial effect on carbohydrate homeostasis. Furthermore, the Randomized EValuation of the Effects of Anacetrapib Through Lipid-modification (REVEAL) trial showed that anacetrapib administration on top of statin treatment significantly reduces cardiovascular events in patients with atherosclerotic vascular disease without any significant increase of adverse events despite its long half-life. Thus, anacetrapib could be useful for the effective management of dyslipidemias in high-risk patients that do not attain their LDL cholesterol target or are statin intolerable, while its role in patients with increased Lp(a) levels remains to be established.
