Urinary sampling for 5HIAA and metanephrines determination: revisiting the recommendations
Authors: Corcuff Jean-Benoît , Chardon Laurence , El Hajji Ridah Ines , Brossaud Julie
Published: June 2017

Context

Biogenic amines such as 5-hydroxy-indole acetic acid (5HIAA) the main metabolite of serotonin or metanephrines (catecholamines metabolites) are used as biomarkers of neuroendocrine tumours.

Objective

To re-evaluate the recommendations for urinary sampling (preservatives, diet, drugs, etc.) as many of the reported analytical interferences supporting these recommendations are related to obsolete assays.

Methods

Bibliographic analysis of old and modern assays concerning preservation, extraction, assay and interferences.

Results

5HIAA may degrade as soon as urine is excreted. Thus, acids as preservatives (hydrochloric or acetic acid) have to be immediately added. Care should be taken not to decrease the pH under 2. Urine preservative for metanephrine assays is not mandatory. Diets including serotonin-, tryptophan- and dopamine-rich foods have to be avoided depending on the biomarkers investigated (bananas, plantain, nuts, etc.). Tryptophan-rich over-the-counter formulas have to be prohibited when 5HIAA has to be assayed. Acetaminophen may interfere with electrochemical detection depending on high-pressure liquid chromatography (HPLC) parameters. No interference is known with mass spectrometric assays but with the one described for metanephrines determination. Some drugs interfere however with serotonin and catecholamines secretion and/or metabolism (monoamine oxidase inhibitors, serotonin or dopamine recapture inhibitors, etc.).

Conclusion

Revisited recommendations are provided for the diet, the drugs and the preservatives before HPLC coupled with electrochemical and mass spectrometry assays.
Hospital-Level Variation in Practice Patterns and Patient Outcomes for Pediatric Patients Hospitalized With Functional Constipation
Authors: Librizzi Jamie , Flores Samuel , Morse Keith , Kelleher Kelly , Carter Jodi , Bode Ryan
Published: June 2017

BACKGROUND AND OBJECTIVE:

Constipation is a common pediatric condition with a prevalence of 3% to 5% in children aged 4 to 17 years. Currently, there are no evidence-based guidelines for the management of pediatric patients hospitalized with constipation. The primary objective was to evaluate practice patterns and patient outcomes for the hospital management of functional constipation in US children’s hospitals.

METHODS:

We conducted a multicenter, retrospective cohort study of children aged 0 to 18 years hospitalized for functional constipation from 2012 to 2014 by using the Pediatric Health Information System. Patients were included by using constipation and other related diagnoses as classified by International Classification of Diseases, Ninth Revision. Patients with complex chronic conditions were excluded. Outcome measures included percentage of hospitalizations due to functional constipation, therapies used, length of stay, and 90-day readmission rates. Statistical analysis included means with 95% confidence intervals for individual hospital outcomes.

RESULTS:

A total of 14 243 hospitalizations were included, representing 12 804 unique patients. The overall percentage of hospitalizations due to functional constipation was 0.65% (range: 0.19%–1.41%, P < .0001). The percentage of patients receiving the following treatment during their hospitalization included: electrolyte laxatives: 40% to 96%; sodium phosphate enema: 0% to 64%; mineral oil enema: 0% to 61%; glycerin suppository: 0% to 37%; bisacodyl 0% to 47%; senna: 0% to 23%; and docusate 0% to 11%. Mean length of stay was 1.97 days (range: 1.31–2.73 days, P < .0001). Mean 90-day readmission rate was 3.78% (range: 0.95%–7.53%, P < .0001).

CONCLUSIONS:

There is significant variation in practice patterns and clinical outcomes for pediatric patients hospitalized with functional constipation across US children’s hospitals. Collaborative initiatives to adopt evidence-based best practices guidelines could help standardize the hospital management of pediatric functional constipation.

Published: June 2017

OBJECTIVES:

To describe 24-hour time-use patterns and their association with health-related quality of life (HRQoL) in early adolescence.

METHODS:

The Child Health CheckPoint was a cross-sectional study nested between Waves 6 and 7 of the Longitudinal Study of Australian Children. The participants were 1455 11- to 12-year-olds (39% of Wave 6; 51% boys). The exposure was 24-hour time use measured across 259 activities using the Multimedia Activity Recall for Children and Adolescents. “Average” days were generated from 1 school and 1 nonschool day. Time-use clusters were derived from cluster analysis with compositional inputs. The outcomes were self-reported HRQoL (Physical and Psychosocial Health [PedsQL] summary scores; Child Health Utility 9D [CHU9D] health utility).

RESULTS:

Four time-use clusters emerged: “studious actives” (22%; highest school-related time, low screen time), “techno-actives” (33%; highest physical activity, lowest school-related time), “stay home screenies” (23%; highest screen time, lowest passive transport), and “potterers” (21%; low physical activity). Linear regression models, adjusted for a priori confounders, showed that compared with the healthiest “studious actives” (mean [SD]: CHU9D 0.84 [0.14], PedsQL physical 86.8 [10.8], PedsQL psychosocial 79.9 [12.6]), HRQoL in “potterers” was 0.2 to 0.5 SDs lower (mean differences [95% confidence interval]: CHU9D −0.03 [−0.05 to −0.00], PedsQL physical −5.5 [−7.4 to −3.5], PedsQL psychosocial −5.8 [−8.0 to −3.5]).

CONCLUSIONS:

Discrete time-use patterns exist in Australian young adolescents. The cluster characterized by low physical activity and moderate screen time was associated with the lowest HRQoL. Whether this pattern translates into precursors of noncommunicable diseases remains to be determined.
Hibridismo y frontera en la literatura marginal contemporánea de Argentina Y Brasil
Authors: Leighton Gabriela , Leal Amanda
Published: June 2017

Con sus similitudes y diferencias, la emergencia de una literatura marginal contemporánea en Brasil y en Argentina es un fenómeno social que se radica en las denominadas favelas y en los barrios o villas. En ese sentido, sus narrativas describen el contexto social vivido en los barrios periféricos, posibilitando que diversos “Yoes” que estaban silenciados “hablen” en un campo literario que era hasta entonces lugar de privilegio y de “alta cultura”. Dicha literatura es muchas veces interpretada desde una perspectiva legitimista o relativista. Sin embargo, esas claves analíticas impiden identificar las especificidades, las desviaciones y los quiebres narrativos presentes en el emergente campo literario de la literatura marginal, o “literatura villera”.
First record of Batrachoides surinamensis (Bloch & Schneider, 1801) and Canthidermis maculata (Bloch, 1786) (Pisces: Teleostei) from Rio Grande do Norte, northeastern coast of Brazil
Authors: Garcia Jr. José , Alves Geovanine Araújo , Oliveira Jorge Eduardo Lins , Carvalho Adriana Rosa
Published: June 2017

A new occurrence each of Batrachoides surinam­ensis and Canthidermis maculata is reported in the northeastern coast of Brazil. This report adds to the known records for both species and increases the regional marine fish richness to 461 species. Following these records, 1.6 tons of C. maculata were landed from May 2016 to January 2017, representing more than 1,500 individuals caught monthly. While it sheds light on the importance of C. maculata, the economic and social role of B. surinamensis remains unknown. Likewise, their conservation status is currently uncertain and further investigation is warranted.

Published: June 2017

This study presents Ctenogobius boleosoma from the São Luis estuarine region, the first record from the state of Maranhão, northeastern Brazil. This species may have gone unrecorded from Maranhão due to the difficulties in collecting gobies by the usual sampling methods, such as gill nets, corking nets, and longlines, even when using nets with an appropriate mesh size.
Amphibians and reptiles from the Mt. Hamiguitan Range of eastern Mindanao Island, Philippines: new distribution records
Authors: Supsup Christian E. , Guinto Faith M. , Redoblado Bernard R. , Gomez Rai S.
Published: June 2017

Despite extensive surveys conducted in the past, many remote areas in the Philippines remain unexplored and many species are unknown to science. The Mount Hamiguitan Range (MHR) is among these areas, containing large remaining forests tracts. In this study, we report new records of amphibians and reptiles from MHR and propose removing two species from the previously listed species from this mountain range. We used standardized techniques to sample populations of amphibians and reptiles in fragmented forests of Mt. Hamiguitan. Our survey resulted in 16 new records of species (four frogs, three lizards and nine snakes). Combining our results with previous studies, the known species diversity from the MHR is now increased to a total of 61 taxa. Our results highlight the underestimated diversity of herpetofauna of Mt. Hamiguitan, and we discuss the importance of repeated surveys for determining species occurrences and assessing their conservation status.

Since the 19th century, Cylindera (Oligoma) paradoxa (W. Horn, 1892) has been recorded from only 10 locations in Sri Lanka, with only 2 of those recorded in the past 30 years. We recently found this species in the Keeragala estate (Ratnapura District) during field surveys. Our new record fills a gap in the knowledge of this species’ distribution in Sri Lanka.
Antyczna tradycja filozoficznych sposobów życia jako wzorzec dla współczesności
Authors: Subczak Marcin
Published: June 2017

W niniejszym artykule prezentuję filozofię rozumianą jako sposób życia i pytam o jej aktualność lub dezaktualizację we „współczesności”. Na początku definiuję to, czym jest filozoficzny sposób życia i czym on się charakteryzuje. Następnie wskazuję na dwa aspekty ludzkiej „natury”, które warunkują realizację tego sposobu życia: konieczność istnienia spójnej tożsamości i całościowego egzystencjalnego projektu (celu).W punkcie drugim ukazuję „współczesność” w jej napięciu między nowoczesnością a „ponowoczesnością”. Nawiązuję tutaj do charakterystyki tej ostatniej, sformułowanej przez Zygmunta Baumana. Natomiast w punkcie trzecim pytam o możliwość funkcjonowania filozofii, jako sposobu życia, w tak zdefiniowanej „współczesności”.Wskazuję, że wyklucza ona takie funkcjonowanie ze względu na postulowaną „płynną tożsamość”, a precyzyjniej mówiąc – na brak tej tożsamości i niemożliwość jej spójnego skonstruowania według przyjętego określonego wzorca. Z drugiej jednak strony zauważam, że – paradoksalnie – „ponowoczesność” może być przestrzenią realizacji filozoficznej egzystencji w momencie, gdy uznamy, że negacja, poczucie obcości i stawianie się w krytycznej opozycji wobec ustalonego porządku były charakterystycznymi cechami antycznego filozofowania, którego paradygmat swą atopicznością wyznaczył Sokrates. Zatem filozoficzny sposób życia możliwy jest do realizacji nawet w tej epoce, która sama ideowo zaprzecza takiej możliwości.
Realist Phenomenology and Philosophy of Religion. A Critical Reflection
Authors: Mezei Balázs M.
Published: June 2017

The aim of the present paper is to show that Catholicism is not a closed segment of contemporary philosophy but rather a rich source of traditions and developments which are alive even today and can help to understand our philosophical situation and contribute to a renaissance of influential philosophy in our culture. In more detail, I shall focus on the importance of Catholic philosophy in its history and present day situation as part and parcel of our general philosophical traditions. I offer a list of models describing the possible relationships between Catholicism and philosophy. I identify the unity model as a model connected to phenomenological realism; and I will detail the important contribution of Josef Seifert to such a phenomenological realism. Phenomenological realism as an expression is offered here as a modification of realist phenomenology, a modification based on the recognition of what I term the entangled nature of reality.
Mistyka św. Jana od Krzyża w filozoficznej koncepcji miłości Karola Wojtyły?
Authors: Pala Amadeusz
Published: June 2017

Artykuł porusza temat wpływu, jaki mogła mieć mistyczna doktryna św. Jana od Krzyża na filozoficzną koncepcję miłości Karola Wojtyły. Stawia się tu tezę, że oddziaływanie to mogło być dwojakie: pośrednie i bezpośrednie.Wpływ pośredni polegałby na przyczynieniu się do przyjęcia przez Wojtyłę postawy filozoficznej, zawierającej dwa sposoby filozofowania: tomistyczny i fenomenologiczny. Postawa ta następnie warunkowałaby podejście Wojtyły do tematu miłości. Natomiast wpływu bezpośredniego można się doszukiwać w tych fragmentach Miłości i odpowiedzialności, gdzie rozważana jest miłość oblubieńcza, która – podobnie jak w mistyce św. Jana od Krzyża – skupia się na idei zjednoczenia osób.
Nordic States: Towards Unity or Diversity?
Authors:   University of Łódź (Poland), Kobierecka Anna
Published: June 2017

The aim of the article is to examine whether Nordic area can be regarded as a homogenous and successfully cooperating region, which is providing one unified political front. Considering many similarities between Nordic states, as for example shared values (equality, women rights, common love of democracy, peace and welfare state), one could say that Nordic states constitute a single and unitary area. What is more, the linguistic, cultural and historical closeness of those states is a fact, but at the same time many differences can be pointed, especially considering their security and foreign policies. Those aspects seem to be the main obstacle in introducing full cooperation in the region. Nevertheless, it is worth noticing that current international developments and appearance of new threats to security are influencing the Nordic states which, as a result, are changing their attitudes towards security policy. Those factors could lead to introducing new dimensions of their cooperation.
Hybrid Power-Sharing in Indonesia
Authors:   Polish Academy of Sciences (Poland), Trzciński Krzysztof
Published: June 2017

The aim of this study is to demonstrate the validity of the thesis that in Indonesia one can find institutions that characterize two power-sharing models which are considered opposites of one another in political theory – centripetalism and consociationalism. In consequence, the Indonesian power-sharing system should be viewed as a hybrid, or mixed, system, and not a typically centripetal system as is usually the case in the literature. At the beginning of this article, a short analysis of Indonesia's political situation is given for the purpose of defining the factors which determined the introduction of inter-segmental power-sharing solutions in that country. This is followed by a description of the specificity of consociationalism and centripetalism. The article goes on to discuss specific institutions of both power-sharing models which exist in Indonesia and ends with some concluding remarks on the thesis advanced at the outset.
The Government’s Remembrance Policy: Five Theoretical Hypotheses
Authors:   Nicolaus Copernicus University in Toruń (Poland), Wawrzyński Patryk
Published: June 2017

Remembrance is a powerful instrument of social mobilisation, identity construction and political competition. Its impact on individual and shared beliefs or attitudes makes it an object of government’s interest, because remembrance can be used to legitimise ideologies or policies. Theoretical considerations of a government’s role as a narrator lead us to the general definition of the government’s remembrance policy, which we understand as a complex of narratives and interpretations presented to influence citizens’ attitudes, behaviours, beliefs and identities. The paper develops the definition with five theoretical hypotheses on the effectiveness of remembrance narratives. It argues that the government’s remembrance policy is myth-motoric, non-scientific, emotional, based on commitment and that it is a type of social influence. The study is an initial verification of theoretical approach, and I believe that my arguments will motivate other researchers to investigate different aspects of a government’s desire to narrate past events.
Terrorism and Media – an Interactive Modelling of a Message: the Research Framework
Authors:   Nicolaus Copernicus University in Toruń (Poland), War Studies University in Warsaw (Poland), Stańco-Wawrzyńska Alicja
Published: June 2017

The report presents theoretical framework of relationships between terrorist organisations and media, and it describes them as an interactive modelling of a message. It introduces the concept of mediatisation of terrorism, and it offers a definition of this process. Moreover, the report develops it with six theoretical hypotheses related to: influence of media on selection of terrorists’ targets, adaptation of an act of terror to the ‘logic of media communication’, personalisation of terrorism and celebritisation of terrorists, creation of biased and oversimplified stereotypes, transformation of terrorist objectives into catch-phrases, as well as a role of political violence in agenda-setting of main news broadcasts. The presented concept will be verified in the ongoing comprehensive, quantitative-and-qualitative study on mediatisation of terrorism in American television, that will investigate the process between September 11, 2001 and the Boston Marathon Bombing in 2013.

ABSTRACT: Plants density in soybean cultivation is an important management practice to achieve high grain yield. In this way, the objective was to evaluate the agronomic traits and grain yield in soybean in different plant densities, in two locations in the south of Minas Gerais. The experimental design was in randomized blocks, arranged in a split plot design, with three replications. Plots were composed of four population densities (300, 400, 500 and 600 thousand plants per hectare) and the subplots were composed of six cultivars (‘BMX Força RR’, ‘CD 250 RR’, ‘FMT 08 - 60.346/1’, ‘NA 5909 RR’, ‘TMG 7161 RR’ and ‘V - TOP RR’) grown in Lavras and Inconfidentes, both in Minas Gerais. At the time of harvest was determined the plant height, lodging, insertion of the first pod, harvest index, number of pods per plant, number of grains, number of grains per pod and yield. Regardless of the soybean cultivar, the plant density of up to 600,000 per ha does not affect grain yield, plant height, lodging, harvest index, and number of grains per pod. The cultivars ‘V-TOP RR’ and ‘BMX FORÇA RR’ showed high grain yield and good agronomic traits in Lavras and Incofidentes.

Published: June 2017

ABSTRACT: This paper presents the main applications of electric vehicles in rural areas, pointing out the trends and challenges for the future. Technological conditions and difficulties faced by the industry for a wide dissemination of this technology are discussed. The paper described the main researches with proposals to overcome the problems of implementing electric tractors, as supply and electricity storage. Technical and economic comparisons between conventional internal combustion tractors and electric tractors are also presented and discussed. The paper showed the existence of barriers to the implementation of electric vehicles in rural areas, as well as the need for batteries technological evolution, which have high costs and for that reason they are very heavy for these purposes, but there are already systems that can be applied to minimize dependence of fossil fuels in this sector and increase the use of sustainable energy.
Simultaneous meningioma and brain metastasis from renal cell carcinoma – a rare presentation. Case report
Authors: Campos Paiva Aline Lariessy , Vitorino Araujo João Luiz , Ferraz Vinícius Ricieri , Esteves Veiga José Carlos
Published: June 2017

ABSTRACT CONTEXT: Brain metastases are the most common tumors of the central nervous system. Because of their high frequency, they may be associated with rare situations. Among these are tumor-to-tumor metastasis and an even a rarer situation called simultaneous brain tumors, which are more related to primary tumors of the reproductive and endocrine systems. CASE REPORT: A 56-year-old male patient with a history of renal cell carcinoma (which had previously been resected) presented with a ventricular lesion (suggestive of metastatic origin) and simultaneous olfactory groove lesion (probably a meningioma). First, only the ventricular lesion was dealt with, but after a year, the meningothelial lesion increased and an occipital lesion appeared. Therefore, both of these were resected in a single operation. All the procedures were performed by the same neurosurgeon. The patient evolved without neurological deficits during the postoperative period. After these two interventions, the patient remained well and was referred for adjuvant treatment. CONCLUSIONS: This study provides the first description of an association between these two tumors. Brain metastases may be associated with several lesions, and rare presentations such as simultaneity with meningioma should alert neurosurgeons to provide the best oncological treatment.

Published: June 2017

ABSTRACT Objective: To analyze the association between excess abdominal fat and healthcare costs related to hypertension and diabetes Mellitus in older adults. Methods: These cross-sectional analyses are part of the Health, Wellbeing and Aging Study conducted in São Paulo, Brazil, with 806 older adults with self-reported hypertension and diabetes Mellitus. The study included the annual costs with medicines, hospital admissions, and outpatient services for hypertension and diabetes Mellitus control. Excess abdominal fat was diagnosed based on waist circumference. Level of physical activity, age, and gender were considered covariates. The sample was divided into two groups according to waist circumference. Multiple logistic regression analyzed the associations between annual costs and waist circumference. Results: The cost of services and hospitalizations (R$551.05; 95%CI=418.27-683.83) and total costs (R$817.77; 95%CI=669.21-966.33) were higher in the excess abdominal fat group. Older adults with high waist circumference had higher odds of increasing annual costs due to medicines (OR=2.6; 95%CI=1.13-3.77), regardless of gender, age, and level of physical activity. Conclusion: Healthcare costs for treating hypertension and diabetes Mellitus in older adults are higher in the presence of excess abdominal fat.
ASSESSMENT OF MIX PROPORTIONS FOR DEVELOPING LIGHTWEIGHT CEMENTITIOUS COMPOSITES WITH WOOD WASTES
Authors: Garcez Monica , Garcez Estela , Machado Aline , Gatto Darci
Published: June 2017

ABSTRACT The main objective of this work was to assess mix proportions for developing lightweight cementitious composites, manufactured with Eucalyptus grandis sawdust. Different wood:cement, water:cement and admixture:cement ratios were used to evaluate physical (water absorption, void ratio and density) and mechanical (compressive strength, static and dynamic modulus of elasticity) properties of the cement-wood composites. Results shows that, bulk density is directly proportional to the compressive strength and elastic modulus, and inversely proportional to the percentage of timber, considering composites with same water:cement ratio, without superplasticizer. The performance of the cement-wood composites, regarding mechanical properties, can be improved if superplasticizer is used to increase paste fluidity. Higher values of bulk density are related to lower void ratio and water absorption and higher compressive strength and modulus of elasticity.

Published: June 2017

ABSTRACT The uncontrolled expansion of human activities may lead to a reduction in vegetation cover, an increase in erosion processes and soil sealing. The aim of this study is to examine forest cover using the Weights of evidence method based on land use maps between the years of 1996 and 2011 in the micro-region of the Campanha Ocidental located in the state of Rio Grande do Sul (Brazil). The spatial database was constructed in SPRING software (version 5.2.1) based on LANDSAT 5 images, which were georeferenced and classified. Geophysical and socioeconomic variables were included in the database for further analysis in Dinamica EGO software (version 2.2.8). In order to parameterize the probabilistic model for the analysis of the dynamics of forest cover change, we calculated the percentage of class change through transition matrices; calculated the intervals for discretization of continuous variables; calculated the weights of evidence (W+); analyzed the correlation between the weights of the input variables for all transitions; simulated future scenarios and; validated the simulated final map based on the historical map. This model was adequate for understanding the variables that most contribute to forest cover change in the region. The results showed that the emergence of new forest areas was influenced by hypsometry, distance to sandy lands and per capita income, while deforestation by rural population and distance to the sandy lands.

Published: June 2017

ABSTRACT This study aimed to assess different types of machines adapted for mechanized forest harvesting activities in order to quantify the degree of compliance with ergonomic principles applicable to forest machines, as well as the ergonomic risks to which workers are exposed. The following machines were evaluated: a feller buncher adapted into a wheel loader; a mini skidder coupled to an agricultural tractor; and a forest loader adapted to an agricultural tractor; operating in the states of Paraná and Minas Gerais. Biomechanical working conditions were assessed by applying a checklist for simplified assessment of the workplace biomechanical conditions. The forced postures assessment was performed using the REBA - "Rapid Entire Body Assessment" method. In turn, ergonomic classification was through guidelines contained in the ergonomic classification manual "Ergonomic Guidelines for Forest Machines". Moreover, the environmental factors noise, temperature and vibration to which the operators of these machines were exposed were assessed. The results showed all assessed machines had ergonomic standards below those indicated in all assessed aspects, mainly related to access and dimensions of the workplace, need to adopt forced postures during working hours, and exposure to environmental factors assessed above tolerance limits. It is concluded that machines adapted for use in forest harvesting processes have shown significant gaps in relation to ergonomic aspects, presenting high and imminent risk of development of occupational diseases in their operators.

Published: June 2017

ABSTRACT Flow cytometry and microsatellite markers were used to determine a genetic fidelity of micropropagated plants from the two Eucalyptus urophylla x E. globulus clones and a Eucalyptus grandis x E. globulus clone derived from adult material. Clones were repeatedly subcultured for 25 subcultures on MS medium supplemented with BA (2.22 µM) and ANA (0.05 µM) for in vitro shoot multiplication. The elongation was performed in MS culture medium supplemented with AIB (2.46 µM) and BA(0.22 µM). The ex vitro rooting and acclimatization phases were lead at the same time. The micropropagated clones showed genetic stability by flow cytometry and microsatellite markers. The results proved that micropropagation, for purposes of rejuvenation, can be a viable technique to generate genetically stable or identical E. globulus hybrid clones.

Published: June 2017

Abstract Objective To evaluate the in vitro and in situ anti-cariogenic potential and bond strength to enamel of materials containing fluoride (F), used for bracket bonding: Transbond XT (GT, negative control), Transbond Plus Color Change (GTF), Transbond-Self-Etching Primer (GSAF) and Vitremer (GV, positive control). Material and method In the in vitro study, the specimens were premolars with bonded brackets (n=12/group). After pH cycling, the F release, bond strength, fracture mode and presence of white spot lesions were assessed. In the in situ study, the specimens were enamel fragments with bonded brackets (n=12/group). Twelve volunteers wore palatal appliances in 4 phases, with cariogenic challenge. Bond strength, fracture mode and change in surface hardness (%SH) were determined. Result Relative to the in vitro study, F release (ppm) was: GT=0.257±0.068c; GTF=0.634±0.100b; GSAF=0.630±0.067b; GV=2.796±1.414a. Only GV showed no white spot lesions. Bond strength values (MPa) were GT=7.62±7.18a; GTF=5.15±6.91ab; GSAF=3.42±2.97bc; GV=2.87±2.09c. Adhesive fracture was the most frequent type, except for GTF. In the in situ study, %SH was: GT=-56.0±18.3a; GTF=-57.6±11.9a; GSAF=-57.1±11.3a; GV=-52.4±25.8a. Bond strength values were GT=9.5±4.4a; GTF=11.1±5.9a; GSAF=13.2± 6.6a; GV=6.6±4.0a. Cohesive fracture in material was the most frequent type, except for GTF. Conclusion Vitremer (GV) showed the highest anti-cariogenic potential in the in vitro study. However, it was not confirmed by the in situ study. Regarding bond strength values from the in situ study, all materials were shown to be adequate for clinical practice.
DOENÇA ÓSSEA INDUZIDA PELOS GLICOCORTICOIDES: MECANISMOS E IMPORTÂNCIA NA PRÁTICA PEDIÁTRICA
Authors: Sarinho Emanuel Sávio Cavalcanti , Melo Verônica Maria Pinho Pessoa
Published: June 2017

RESUMO Objetivo: Descrever os mecanismos pelos quais os glicocorticoides provocam osteoporose, com risco consequente de fraturas, integrando esse conhecimento a uma possível mudança de conduta dos profissionais de saúde. Fontes de dados: Foi realizada pesquisa aprofundada nas bases de dados (SciELO, PubMed, Medline e Scopus), buscando consensos, artigos de revisão, incluindo revisões sistemáticas e meta-análises, publicados em inglês, entre 2000 e 2016. As palavras-chaves utilizadas na busca foram glicocorticoides, esteroides, fraturas, osteoporose, saúde óssea, crianças e adolescentes. Síntese dos dados: A revisão foi dividida em quatro tópicos principais: 1) introdução, com breve enfoque nas fraturas em pediatria; 2) osteoporose em crianças e adolescentes, destacando-a como causa silenciosa de fraturas; 3) glicocorticoides e doença óssea secundária, com a descrição dos mecanismos deletérios desse grupo de esteroides na estrutura óssea; 4) efeitos moleculares do excesso de glicocorticoides no osso, com o detalhamento dos mecanismos nocivos a nível molecular do tecido ósseo. Conclusões: Os glicocorticoides em excesso determinam doença óssea precoce, favorecendo a ocorrência de fraturas. Dessa forma, uma criança ou adolescente que requer corticoterapia, sobretudo crônica e sistêmica, mas também em ciclos repetidos com doses cumulativas altas, necessita de cuidados e orientações relacionados à saúde óssea logo ao início do tratamento. Por outro lado, aqueles com fratura, mesmo entrelaçada a um trauma, podem sinalizar fragilidade óssea subjacente e desconhecida, incluindo a secundária ao uso de glicocorticoides e à deficiência de vitamina D.

Resumo: O presente artigo devota-se a oferecer um panorama extensivo da recepção das ideias de Michel Foucault na pesquisa educacional brasileira, por meio dos resultados de uma investigação sobre a produção acadêmica de matriz foucaultiana em 52 periódicos educacionais, entre 1990 a 2014. Consoante a uma estratégia de endereçamento à massa documental que fosse capaz de abdicar do ajuizamento dos usos das ideias do pensador, 401 artigos que sugeriam uma apropriação da teorização foucaultiana como modo de trabalho foram selecionados e, então, analisados em conjunto. Ao final do texto, são formulados alguns apontamentos acerca dos limites atuais e das possibilidades futuras dos estudos foucaultianos na educação brasileira.
DESAFIOS DA DIVERSIDADE EM SALA DE AULA: UM ESTUDO SOBRE PERFORMANCES NARRATIVAS DE CRIANÇAS IMIGRANTES
Authors: Hartmann Luciana
Published: June 2017

RESUMO: Este artigo procura refletir sobre performances narrativas produzidas por crianças imigrantes em um contexto escolar marcado por intensa diversidade cultural. A análise foi fundamentada nos dados obtidos por meio da pesquisa etnográfico-propositiva intitulada Pequenos Narradores, realizada entre os anos de 2014 e 2015, em duas escolas públicas de ensino fundamental de Paris, França, nas chamadas CLIN - classes de iniciação do francês para crianças não francófonas. Como estratégia metodológica, foram realizadas diversas atividades lúdicas no sentido de favorecer a produção narrativa na sala de aula. A agência das crianças na escolha do que e como contar foi analisada sob a perspectiva dos estudos da performance. Constatou-se que, nesse contexto, as performances narrativas constituem um elemento importante não apenas na tradução e organização das experiências dessas crianças imigrantes, mas, sobretudo, na criação e transformação dessas experiências diante da realidade de vida no novo país.
Sources of Chinese Learners’ Self-efficacy in Learning English Pronunciation
Authors: Yang Xin
Published: June 2017

This study investigated the sources of Chinese learners’ self-efficacy in English pronunciation learning to reveal their predicting power in English pronunciation performance by Chinese learners. Unlike some previous studies which found a significant correlationship between the sources of self-efficacy and learners’ academic achievement, the findings indicate that of the four sources, social persuasion are not highly correlated with learners’ pronunciation performance while mastery experience, vicarious experience, and physiological states are significantly correlated with learners’ pronunciation performance with the correlation coefficients at .48, .26 and .29 respectively. However, only mastery experience shows a significant predicting power in Chinese learners’ performance of English pronunciation.
Persuasion in Journalism: A Study of Metadiscourse in Texts by Native Speakers of English and Iranian EFL Writers
Authors: Moghadam Farzane Deliery
Published: June 2017

Metadiscourse is a set of linguistic devices used to communicate attitudes and mark the structural properties of a text. This study explored the frequency of occurrence of metadiscourse devices, and the role they play in the construction of persuasion in opinion articles written by English native speakers and Iranian EFL (English as a Foreign Language) writers. A corpus of 60 opinion articles, 30 by American writers and 30 by Iranian EFL authors, was collected and examined using Hyland’s (2005) model of metadiscours. The articles were taken from newspapers and news websites in October 2014 and were published in the period from May, 2013 to October, 2014. A quantitative analysis was conducted to determine the frequency of occurrence of metadiscourse devices. The non-parametrical Mann-Whitney U test was used to see if the frequency counts in the two corpora differ statistically.  Findings suggested that metadiscourse devices were present in the both groups; however, there were variations as to the number of code glosses, hedges, self-mentions and engagement markers. Genre-driven conventions, culture-driven tendencies and Iranian columnists’ extend of English command were the factors affecting the choice and frequency of metadiscourse markers.
Strategic Management and Performance Measurement – A Connected or Disconnected Duo? Evidences from Croatian Public Administration
Authors: Manojlović Romea
Published: June 2017

The paper examines the link between strategic management and performance measurement in the public sector. The main hypothesis is that the stages of strategic management development are positively correlated with the number of performance dimensions measured by public organisations. In order to examine the stated hypothesis results from the empirical research conducted in Croatian public administration are being presented. A questionnaire has been sent to 253 central and local organisations and additional interviews have been conducted. The results confirm the hypothesis and determine that the enhancement of strategic planning and management is one of the main stimuli for performance measurement in Croatia.
Interest Representation, Interest Alignment and the Role of Seeking Consensus in the Renewal Process of Hungarian State Management
Authors: Lentner Csaba , Parragh Bianka
Published: June 2017

The interest representation of owners, employee participation and endeavours to achieve consensus can be identified as the operational factor of well-managed publicly owned companies in the renewal process of state management. Higher quality expectations that appear to arise in respect of public services and the higher quality standard expected of public sector employees in the course of the performance of their duties all point in the direction of achieving a well-functioning state. This study focuses on representing the interest of the state as an owner, the changes in the institutional system of interest alignment and the search for consensus, the development that has materialised over the past decades, its alternatives arising from the regulatory environment and the attitudes and motivations of economic actors affected by the trend in the Hungarian economic environment. The analysis highlights the balancing role of the state, which is becoming more prominent.

From Evil Queen to Disabled Teen: Frozen Introduces Disney's First Disabled Princess
Authors: Resene Michelle
Published: June 2017

Disney's Frozen represents a landmark for the animation giant due not only to its immense popularity but also its introduction of the studio's first disabled princess. In order to make Elsa's story possible, the animators use a combination of narrative devices including the introduction of a second princess, whose story fulfills the audience's expectation for a traditional "princess journey," their patented aesthetic of cuteness, and the encoding of disability as fantasy. Although Elsa's disability is encoded as a magical ice power, the language the film uses to talk about her condition maps on to the experiences of people with physical, mental, and intellectual disabilities in recognizable ways. Meanwhile, her status as a much-beloved princess figure allows the animators at Disney to position disability as a universal experience and in turn to create empathy for PWDs both on and off screen.

O inseto Helicoverpa armigera recentemente registrado no Brasil é uma das maiores pragas da agricultura mundial. Pode atacar mais de 200 espécies de plantas e possui populações resistentes a diversos inseticidas. A utilização de microrganismos com potencial patogênico contra insetos é uma alternativa aos inseticidas. Essa pesquisa foi realizada com o objetivo de determinar a suscetibilidade de lagartas de H. armigera à produtos formulados à base de Bacillus thuringiensis (Bt) Para os experimentos, foram utilizados os produtos comerciais Dipel® e Agree®, os quais tiveram sua concentração ajustada para 108 conídios viáveis ml-1. Essa concentração foi aplicada sobre dieta artificial, a qual foi colocada em uma placa de Petri que continha 10 lagartas de primeiro instar. Foram realizadas cinco repetições para cada produto. As avaliações foram feitas a cada 24h durante sete dias. Os produtos comerciais Dipel® e Agree® causaram, respectivamente, 100% e 94% de mortalidade das lagartas de H. armigera. Esse resultado mostra o potencial de produtos à base de Bt sobre H. armigera.

Extremos climáticos consistem em eventos cuja variável contenha valores com grande desvio em relação a sua tendência estatística, os quais são peculiares para cada região e apresentam potencial para influenciar nas atividades agropecuárias locais. Logo, objetivou-se descrever e analisar a tendência da variabilidade dos extremos elevados de temperatura do ar obtidos na estação convencional da cidade de Barreiras, Bahia. A análise foi realizada utilizando dados de temperatura máxima do ar registrados em frequência diária do ano de 1995 ao ano de 2014, disponibilizados pelo Instituto Nacional de Meteorologia (INMET). Os valores extremos elevados foram definidos como sendo aqueles superiores ao nono decil. Os valores do nono decil apresentaram média de 37,46ºC. Observou-se que houve uma tendência de diminuição da frequência em que ocorrem extremos de temperatura elevada.

A cotonicultura é uma atividade praticada em grande escala no Brasil e tem grande importância social e econômica, sendo de fundamental importância o uso da irrigação Para um manejo de irrigação mais racional, o monitoramento dos parâmetros fisiológicos da planta se destaca como o controle ideal. Assim, objetivou-se verificar a variação do índice de estresse hídrico na cultura do algodão irrigado (determinado através de termômetro de infravermelho) em função do déficit de umidade no solo. O estudo foi realizado em Fazenda, durante o período de 10 de março a 11 de junho do ano de 2015. Foram coletadas, amostras de solo indeformadas para determinação da umidade atual, conforme o Método-Padrão de Estufa. O cálculo do Crop Water Stress Index (CWSI) foi feito em função dos valores de: temperatura foliar, umidade relativa do ar, e temperatura do ar adquiridos por meio de um termômetro infravermelho. Valores de CWSI variam de forma proporcional ao déficit de umidade no solo. A metodologia tem potencial para ser utilizada na realização do manejo de irrigação.

Biomateriais são substâncias de origem sintética ou natural que substituem e/ou estimulam sistemas biológicos que deixaram de ter suas funções, como exemplo a restauração de funções teciduais. Tendo em vista o potencial antioxidante da norbixina (carotenoide dicarboxílico encontrado na Bixa orellana L.) e de biodegradabilidade e biocompatibilidade do polihidroxibutirato (PHB) (polímero natural sintetizado a partir de bactérias), objetivou-se preparar uma membrana a partir destes dois constituintes com a adição do reagente etilenoglicol (PHB/norbixina/etilenoglicol) para avaliar seus efeitos genotóxico por meio do teste de micronúcleo. Para este estudo, 15 ratos foram divididos em 3 grupos: A - a membrana foi introduzida no peritônio dos animais através de uma laparotomia; B - apenas uma laparotomia com água destilada; C - injeção de ciclofosfamida em dose única de 50 mg / kg por via intraperitoneal. Foi coletado material de medula óssea de cada rato para realizar o teste de micronúcleo. Em conclusão, o teste de micronúcleo sugere que a membrana não é genotóxica.
