Published: June 2019

With rapid changes in information and communication technologies, it is no longer sufficient for language teachers and pre-service teachers (PTs) to know how to use existing digital tools. They also need to be digitally literate in order to critically evaluate such tools and platforms for safe, wise, and productive use. Within a qualitative approach, this study investigated Turkish PTs’ conceptualisation of digital literacy. This included an exploration of how PTs defined this concept, what kind of tools they used, and for which purposes they preferred to use digital tools. First, we found that PTs concept of digital literacy consist of many levels from knowledge to use, and to critical, creative, and collaborative use. Second, we observed that university professors play an important role in the development of digital literacy levels of PTs. Third, it was found that PTs use social media platforms heavily for various purposes, however, we identified a need for further guidance in supporting PTs' use of these platforms for their professional development. The findings of this study shed light on the current digital literacy skills of PTs in Turkey and will be beneficial for educational policy makers and teacher trainers in teacher education for the twenty-first century.

Articulações liberais e iliberais da islamofobia na Alemanha e na França
Authors: Mendelski Bruno
Published: June 2019

Situado nas discussões acerca da integração dos muçulmanos na Europa, argumenta-se que a islamofobia está gradualmente tornando-se institucionalizada na Alemanha e na França. Isso ocorre em razão de uma articulação entre políticas liberais e iliberais. O primeiro tipo contrapõe os muçulmanos a valores como igualdade de gênero e secularismo; o segundo situa o Islã diante os valores cristão-ocidentais. Metodologicamente, compara-se os discursos sobre o Islã, as leis sobre a regulação religiosa no espaço público (Alemanha e França) e o estado de emergência/lei antiterrorismo (França). O artigo aponta que a islamofobia é mais aprofundada na França do que na Alemanha. Ambos experenciaram leis que indiretamente restringiram a liberdade religiosa dos seus cidadãos muçulmanos nos anos 2000, entretanto Paris executou novas medidas (leis do burkini, estado de emergência/lei antiterrorismo) nos anos 2010. Estas recentes políticas públicas reduziram ainda mais as liberdades dos muçulmanos franceses. O declínio do item “liberdades civis” no Relatório Anual da Freedom House (2017) e a queda francesa de “full democracy” para “flawed democracy” no The Economist Democracy Index (2015) fornecem evidêncas para apoiar o argumento.
A exaltação polissêmica do conceito de território: uma nova abordagem no efêmero período das políticas brasileiras de desenvolvimento territorial
Authors: Melo William , Vieira Camila Da Silva
Published: June 2019

Neste paper, os autores visam problematizar alguns pressupostos conceituais erigidos com as últimas políticas de desenvolvimento territorial executadas pelo extinto Ministério do Desenvolvimento Agrário (MDA) nos governos de Fernando Henrique Cardoso; Luís Inácio Lula da Silva e Dilma Rousseff. Sendo assim, baseando-se na compreensão do território como uma esfera multidimensional, na importância da participação e do combate a pobreza em prol do desenvolvimento, este paper abordará: 1) o território na perspectiva do conceito de multiterritorialidade (HAESBAERT, 2004); 2) os demais modelos de políticas territoriais (modelo europeu e latino americano) que se utilizam ou se utilizaram de pressupostos conceituais em prol do desenvolvimento territorial; 3) a importância das políticas sociais como acréscimos estratégicos para as ações que fortalecem o desenvolvimento agrário brasileiro e;4) ressaltar a importância do Programa Território da Cidadania (PTC) como um importante avanço nas discussões e propostas para a questão agrária brasileira, demonstrando como o extinto programa colocava-se como uma ação favorável ao desenvolvimento territorial e de combate à extrema pobreza. Quanto ao método utilizado para o alcance das considerações realizadas, foi empregada a análise de documentos acrescida de revisão bibliográfica, o que permitiu o levantamento das fragilidades e potencialidades dos respectivos programas de desenvolvimento territorial brasileiro, entre os anos de 1994 a 2014.

Este artigo tem como objetivo traçar um breve quadro das lutas políticas que seconformaram em torno da produção e do consumo da carne nas últimas décadas,quando uma série de controvérsias geradas por riscos e implicações éticas,alimentares, sociais e ambientais dessa cadeia se alastraram na esfera públicaglobal. Impelidos por tais preocupações, uma variedade de movimentos sociais temse constituído em torno de pautas como vegetarianismo/veganismo, comércio justo,bem-estar animal, ambientalismo, etc., e disputado na arena pública os termosnormativos que envolvem a valoração material e simbólica da carne em nossasociedade. Esse trabalho se propõe a mapear os principais atores coletivos e osdiscursos por eles mobilizados contra a industria animal segundo três eixos críticos:movimentos animalistas, consumo político e militância socioambiental, de forma aapreender os recursos argumentativos que esses atores sociais utilizamdiscursivamente na difusão de seus projetos e visões de mundo e analisar de queforma intentam capturar o imaginário coletivo e mobilizar e definir alternativas nosentido da ação. A despeito das várias camadas de consensos e discordânciassobre o tema, observamos que esses movimentos transformaram a carne em um oobjeto altamente político, desestabilizando a prevalecente visão normativa desteproduto como um símbolo de progresso e introduzindo novos valores e práticascomo forma de legitimar uma outra realidade alimentar.

Authors: Litvinenko V. N. , Vikulin I. М. , Gorbachev V. E.
Published: June 2019

The paper considers the causes and mechanisms of the influence of defects and impurities on the reverse current of the Schottky diode. The influence of two getter regions, which were created by different technologies on the working side and the reverse side of the plate, on the value of the reverse current of diodes was experimentally investigated, and the physical factors of such influence were analyzed. The proposed technology for creating getter regions allows one to significantly reduce the reverse current of diodes and increase the product yield.

Published: June 2019

The central nucleus of the amygdala (CeA) is a brain region implicated in anxiety, stress-related disorders and the reinforcing effects of drugs of abuse. Corticotropin-releasing factor (CRF,Crh)acting at cognate type 1 receptors (CRF1,Crhr1) modulates inhibitory and excitatory synaptic transmission in the CeA. Here, we used CRF1:GFP reporter mice to characterize the morphological, neurochemical and electrophysiological properties of CRF1-expressing (CRF1+) and CRF1-non-expressing (CRF1–) neurons in the CeA. We assessed these two neuronal populations for distinctions in the expression of GABAergic subpopulation markers and neuropeptides, dendritic spine density and morphology, and excitatory transmission. We observed that CeA CRF1+ neurons are GABAergic but do not segregate with calbindin (CB), calretinin (CR), parvalbumin (PV), or protein kinase C-δ (PKCδ). Among the neuropeptides analyzed,PenkandSsthad the highest percentage of co-expression withCrhr1in both the medial and lateral CeA subdivisions. Additionally, CeA CRF1+ neurons had a lower density of dendritic spines, which was offset by a higher proportion of mature spines compared to neighboring CRF1– neurons. Accordingly, there was no difference in basal spontaneous glutamatergic transmission between the two populations. Application of CRF increased overall vesicular glutamate release onto both CRF1+ and CRF1– neurons and does not affect amplitude or kinetics of EPSCs in either population. These novel data highlight important differences in the neurochemical make-up and morphology of CRF1+ compared to CRF1– neurons, which may have important implications for the transduction of CRF signaling in the CeA.
Alienated Labor's Hybrid Subjects: Sorry to Bother You and the Tradition of the Economic Rights Film
Authors: Torchin Leshu
Published: June 2019

Leshu Torchin uses Sorry to Bother You, Boots Riley's genre-defying take on race, slavery, and capitalism in 21st century America, as a launching pad for a broader discussion of what she terms the “economic rights” film. Often global in scope, these films argue for rights to sustenance, shelter, education, health, and labor while mapping out the myriad systems that impede access to these rights. Torchin suggests that Sorry's playful hybridity, combining science fiction, performance art, and even corporate-video mockumentary to invoke recent experimentations in black American media, belies a preoccupation around labor that positions the film within the “economic rights” film's robust legacy.

FQ Columnist Bilal Qureshi examines two recent German historical dramas that address the cultural and artistic process of grappling with the country's Nazi and Communist past: Florian Henckel von Donnersmarck's Werk ohne Autor (Never Look Away, 2018) and Christian Petzold's Transit (2018). He queries the two films’ highly divergent receptions at home and abroad and asks what Germany's rejection of the lush romanticism of Never Look Away—and embrace of Christian Petzold's unresolved puzzles—can tell us about the shifting grounds of how history is seen and interpreted on-screen in this moment.

Published: June 2019

Introduction: The efficacy of mesenchymal stem cells (MSCs) for cardiomyopathy remains controversial. We conducted a systematic review and meta-analysis to explore the influence of MSCs versus placebo on the treatment efficacy of cardiomyopathy.
Methods: We searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through November 2018 for randomized controlled trials (RCTs) assessing the treatment efficacy of MSCs versus placebo for cardiomyopathy. This meta-analysis was performed using the random-effect model.
Results: Five RCTs were included in the meta-analysis. Overall, compared with the control group for cardiomyopathy, MSCs treatment showed significantly positive effect on LVEF (MD = 5.85; 95% CI = 3.88 to 7.83; P < .00001), NYHA classification (MD = -1.11; 95% CI = -1.45 to -0.77; P < .00001), LVEDd (MD = -3.00; 95% CI = -5.37 to -0.64; P = .01), and the proportion of fixed defects (MD = -4.22; 95% CI = -6.91 to -1.52; P = .002), but had no obvious influence on death (RR = 0.42; 95% CI = 0.12 to 1.50; P = 0.18) or adverse events (RR = 1.14; 95% CI = 0.70 to 1.86; P = .59).
Conclusion: MSCs treatment showed favorable impact on LVEF, NYHA classification, LVEDd, and the proportion of fixed defects for cardiomyopathy patients.

Bruce Baker, a preeminent Drosophila geneticist who made fundamental contributions to our understanding of the molecular genetic basis of sex differences, passed away July 1, 2018 at the age of 72. Members of Bruce’s laboratory remember him as an intensely dedicated, rigorous, creative, deep-thinking, and fearless scientist. His trainees also remember his strong commitment to teaching students at every level. Bruce’s career studying sex differences had three major epochs, where the laboratory was focused on: (1) sex determination and dosage compensation, (2) the development of sex-specific structures, and (3) the molecular genetic basis for sex differences in behavior. Several members of the Baker laboratory have come together to honor Bruce by highlighting some of the laboratory’s major scientific contributions in these areas.
Management of two taurodont primary molars with pulp involvement using calcium-enriched mixture cement pulpotomy in a patient with accompanied drug reaction with eosinophilia and systemic symptoms syndrome: a case report
Authors: Kamareh Sanaz , Kazem Majid , Foroozandeh Maryam , Gohari Atefeh
Published: June 2019

Background: Taurodontism is considered a variation in tooth morphology associated with several syndromes.
Case Presentation: This report presents a case of taurodontism associated with drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. A 5-year-old girl, with a history of DRESS syndrome, was referred to the department of pediatric dentistry at the School of Dentistry, Shahid Beheshti University of Medical Sciences, with a chief complaint of toothache. Clinical and Radiographic examinations showed deep carious lesions with large pulp chambers and short roots present in relation to second mandibular primary molars. Routine pulpectomy could not be performed as a result of complex tooth morphology. Instead, we played a deep pulpotomy with calcium-enriched mixture cement agent, and the crowns were restored. Follow-up observations after six and 12 months showed that the tooth was asymptomatic, clinical and radiographic examinations revealed no swelling, no sensitivity to percussion and palpation.
Conclusion: In patients with carious taurodont deciduous teeth, deep pulpotomy with biomaterials such as calcium-enriched mixture cement can result in favorable outcomes.
Synthesis of ordered mesoporous silica MCM-41 with controlled morphology for potential application in controlled drug delivery systems
Authors: Oliveira D. M. , Andrada A. S.
Published: June 2019

Abstract MCM-41 is one of the most studied mesoporous ceramics for drug delivery systems. Its high specific surface area and mesoporosity allow high adsorption capacity. Even though there are many studies published in the biomedical field, there are no reports of commercial applications of MCM-41 so far. One of the possible justifications is the lack of morphological control during conventional synthesis. Therefore, modifications in the reaction parameters of the MCM-41 conventional synthesis were tested in this paper, aiming to obtain particles with reduced diameter and agglomeration. It was observed that both the increase in the water molar proportion and the decrease in the stirring time resulted in particles with reduced size. Furthermore, the control of the tetraethyl orthosilicate (TEOS) dropping rate and the addition of triethylamine (TEA) improved the dispersion of the system, but they also decreased the particle size, and therefore van der Waals interactions promoted re-agglomeration.
Mechanical and bioactivity assessment of wollastonite/PVA composite synthesized from bentonite clay
Authors: Adams L. A. , Essien E. R. , Kaufmann E. E.
Published: June 2019

Abstract Glass/polymer composites can mimic the natural structure of bone by possessing a fiber-matrix configuration which provides appropriate physical and biological properties. Wollastonite ceramics are known for their promising bioactivity and biocompatibility when applied in bone regeneration. Polyvinyl alcohol (PVA) has various attractive properties including biocompatibility and degradability which may be exploited as a polymer matrix in composites for biomedical applications. Therefore, a cost-effective method of preparing wollastonite/PVA composites is desirable by starting from bentonite clay as a silica source for the glass, instead of traditional alkoxysilanes. The composite prepared was characterized by mechanical testing, scanning electron microscopy, X-ray diffractometry and Fourier-transform infrared spectroscopy to evaluate its compressive strength, morphology, phase composition and bioactivity, respectively. Results obtained revealed for the composite a compressive strength of 0.3 MPa, the ability to induce apatite on its surface when immersed in a simulated body fluid for 7 days and desirable controlled degradation. Hence, this method can be up-scaled for preparation of wollastonite/PVA composite commercially for possible use in bone regeneration.

Published: June 2019

Abstract Hydroxyapatite (HAp) is a bioceramic widely studied due to its chemical similarity with the mineral component of bones. Besides, it is biocompatible, bioactive and thermodynamically stable in the body fluid what poses it as an attractive material for a wide range of applications in the biomedical field. Several efforts have been focused on the synthesis of particles of this material aiming to the precise control of size and morphology, porosity and surface area. HAp is widely used as an implant for bone tissue regeneration, as a coating for metallic implants and in a drug-controlled release. In this sense, the objective of this review is to gather information related to HAp, providing readers with information about synthesis methods, material characteristics and their applications.

Authors: Cruvinel C.A.T. , Cruvinel T.M.A. , Aires L.P.N. , Rodrigues R.F. , Melo A.P.F.
Published: June 2019

ABSTRACT Were used twelve (12) adult anteaters (Myrmecophaga tridactyla), adults, 6 (six) males and 6 (six) females, weighing from 20 to 27.32kg from free life. The thoracic cavity was opened until visualization of the whole heart and lungs and later injection of the coronary vessels. The right coronary artery emerged through a single coronary ostium of the aorta, 50%, emitting the intermediate branch and the subsinuous interventricular branch, had a path directed to the subsurface interventricular groove. In the other 50%, the right coronary artery was not present, showing only its branches, intermediate branch and subsurface interventricular branch with emergence of the aorta. Left coronary artery presented, in 83.33%, origin from the aorta in single ostium, issuing the circumflex and interventricular paraconal branches. In 16.66%, the left coronary artery was not evidenced originating from the aorta, but its branches, circumflex and interventricular paraconal.

RESUMO O objetivo do presente estudo foi correlacionar os valores de reticulócitos pontilhados e agregados obtidos por metodologia manual com a metodologia automática de contagem de reticulócitos totais em amostras de sangue de gatos anêmicos, analisados em um contador hematológico com citometria de fluxo. Para isso, 40 amostras de sangue de pacientes felinos anêmicos, independentemente de idade e sexo, foram utilizadas para a determinação das contagens absolutas de reticulócitos totais pela metodologia automatizada por citometria de fluxo fluorescente e pela técnica manual com corante supravital, em duplicata. Na contagem manual, houve a discriminação entre reticulócitos pontilhados e agregados. Para a correlação entre os métodos, foi realizada a análise de regressão de Passing-Bablok. A média do hematócrito dos gatos foi de 15,25%, tendo a maioria dos gatos (32,5%) apresentado anemia moderada (hematócrito = 17,81%). Como resultados, a análise de regressão demonstrou que a correlação entre a contagem absoluta total automática foi superior à contagem manual de reticulócitos agregados (rho= 0,71; P<0,001) do que a contagem absoluta de reticulócitos pontilhados (rho= 0,68; P<0,001). Os resultados apresentados sugerem que a contagem de reticulócitos total absoluta realizada pelo analisador hematológico ProCyte Dx em gatos anêmicos se refere à contagem absoluta de reticulócitos. Dessa maneira, recomenda-se que os valores possam ser utilizados para a avaliação imediata da condição hematológica de gatos anêmicos.

Published: June 2019

ABSTRACT The aim of this study was to evaluate the frequency of isolation of agents causing subclinical mastitis in a herd and to estimate production losses associated with SCC> 200,000cells/mL. Three 7-day interval microbiological cultures were performed in all lactating animals from the same farm that was evaluated from June to July. To evaluate the negative and positive isolation frequencies between the lactation phases, a Chi-square test was performed. Simple linear regressions were performed to evaluate the lactation curve of animals grouped by pathogens isolated from negative cows in the microbiological culture and with SCC <200,000cells/mL. To estimate the production losses between the groups, regression coefficients were used. Results found in this experiment were: Culture-negative cows with SCC ≥ 200,000cells/mL, cows testing positive in milk culture, with SCC <200,000cells/mL and cows testing positive in milk culture, with SCC ≥ 200,000cells/mL. Milk production was -3.5; -0.5 and -4.27kg, respectively, when compared to culture-negative cows with SCC <200,000cells/mL. Cows infected with yeast cells, Coagulase-negative staphylococci (CNS), Staphylococcus aureus and environmental streptococci produced -3.42; -0.5; -0.168 and -2.5kg of milk when compared to culture-negative cows with SCC <200,000cells/mL. SCC indicates an inflammatory reaction in the mammary gland and it is directly associated with milk production losses and with presence of microorganisms in the mammary gland.

RESUMO A grama missioneira gigante (Axonopus catharinensis Valls) é uma espécie forrageira que merece ser melhor investigada tanto pura como recebendo a inclusão de leguminosas. Objetivou-se avaliar o consumo de MS por ovinos pastejando grama missioneira gigante com ou sem acesso a pastos de amendoim forrageiro (Arachis pintoi cv. Amarillo). Para isso, foi conduzido um experimento prévio com cordeiros alojados em gaiolas metabólicas, gerando-se uma equação para a estimativa do consumo tomando como base a excreção fecal de proteína bruta (PBf), que apresentou R2= 0,91. Em um segundo experimento, foi avaliado o consumo de forragem por ovinos em pastos de grama missioneira gigante com duas alturas de entrada (25 ou 35cm), com ou sem acesso a áreas de amendoim forrageiro por duas horas diárias. A altura de entrada na grama missioneira gigante não alterou o consumo total de MS, mas o acesso aos piquetes da leguminosa aumentou o consumo em aproximadamente 20%. Em conclusão, a grama missioneira gigante pode ser manejada com alturas de entrada entre 25 e 35cm, enquanto o acesso a áreas de amendoim forrageiro por duas horas diárias aumenta o consumo de MO por cordeiros pastejando a missioneira.

ABSTRACT A study was conducted to evaluate the effect of chlorogenic acid (ChA) added pre-cooling and its combination with caffeine added during warming on cooled-stored boar semen parameters. Ten ejaculates were diluted in commercial extender with or without 4.5mg/ml ChA and stored at 15°C. After 0, 24 and 72 hours of storage, aliquots of these doses were taken and incubated at 37°C in the presence or absence of 8.0mM caffeine. Semen quality was evaluated after 10 and 120 minutes of incubation. The ChA increased (P <0.01) the sperm motility, viability, acrosomal integrity and the percentage of spermatozoa with high mitochondrial activity (PMHA), however, decreased (P <0.01) the malondialdehyde (MDA) concentration. Caffeine increased (P<0.05) the sperm motility, viability, PMHA and the MDA concentration and reduced (P <0.05) the acrosome integrity. When associated (ChA+caffeine), there was an increase (P <0.05) in sperm motility and viability, PMHA and acrosome integrity. The addition of ChA to the dilution medium improves the quality of the swine inseminating doses. The addition of caffeine during re-warming is only recommended when the semen is stored for prolonged periods (72h), and the inseminating dose should be used immediately after its addition.

ABSTRACT The present study assessed and compared the effects of hypotonic enteral electrolyte solutions administered by nasoesophageal tube in continuous flow in dogs submitted to water restriction on packed cell volume; total serum protein and serum osmolarity concentrations; blood volume; plasma glucose and lactate levels; blood gas analysis, anion gap, and strong ion difference. Six adult dogs were used (four males and two females). All animals were submitted to both proposed treatments in a crossover design 6×2. The treatments were as follows: ESmalt consisting of 5g sodium chloride, 1g potassium chloride, 1g calcium acetate, 0.2g magnesium pidolate, and 9.6g maltodextrin that were diluted in 1.000mL water (measured osmotic concentration of 215mOsm L−1) and ESdext consisting of 5g sodium chloride, 1g potassium chloride, 1g calcium acetate, 0.2g magnesium pidolate, and 9.6g dextrose that were diluted in 1.000mL water (measured osmotic concentration of 243mOsm L−1). All solutions were administered at 15ml kg−1 h−1 for 4 hours. Both solutions increased the plasma volume in dehydrated dogs without causing adverse effects. However, ESmalt was more effective in promoting the increase in blood volume.

RESUMO As enzimas fibrinolíticas podem ser obtidas de micro-organismos por meio de processos fermentativos. O presente trabalho teve como objetivo avaliar a produção e extração integrada da protease fibrinolítica de Mucor subtilissimus UCP 1262 usando sistema de duas fases aquosas (SDFA). O processo integrado foi realizado para avaliar a produção, partição e recuperação da protease fibrinolítica, segundo planejamento experimental 23, utilizando como variáveis independentes a massa molar do polietileno glicol (PEG), a concentração do PEG e a concentração do sulfato de sódio. A maior atividade fibrinolítica (15,40U/mL) foi obtida na fase rica em sulfato de sódio no ensaio composto por 10% de sal e 18% de PEG 8000 (g/mol). Recuperações superiores a 80% foram obtidas. A protease fibrinolítica apresentou pH ótimo 7,0, estabilidade entre os pH 6,0 e 8,5, temperatura ótima 50°C, sendo estável de 10°C a 50°C. A enzima foi classificada como uma serino protease, com massa molecular de 52kDa. Como resultado, o processo é notavelmente eficaz para pré-purificar a protease fibrinolítica com baixo custo e rapidez significativa. Quando comparada a outras técnicas de produção e purificação isoladas, a fermentação extrativa é um processo digno a ser substituto das etapas iniciais de separação convencionais

Commercial semen of Santa Inês rams were used and five treatments were performed: traditional Percoll and mini-Percoll (MP) techniques (I- 5000 x g, 5min; II- 2500 x g, 5min; III- 1250 x g, 5min; IV- 700 x g, 10min). At post-thawing (PT) and post-selection protocols (0h), samples were assessed for spermatozoa recovery rate, motility, plasma membrane (PM) integrity, sperm capacitation and morphology and incubated at 37 C for 1, 2 and 3h. The sperm recovery rate averaged 9.1±1.4%, and most motility parameters were similar (P> 0.05) among protocols. VCL (µm/s) was higher (P< 0.05) after MP-II, III and IV (66.1±4.5) than traditional Percoll (46.3±4.9). Capacitation status and PM integrity were similar (P> 0.05) among treatments. For the first time, we have demonstrated the reduction of the gradient volume and centrifugation time associated with an increase on centrifugation force at Percoll can be successfully used for frozen-thawed ram sperm selection. MP may be used instead of traditional Percoll, decreasing costs and semen handling time.

Resumo Objetivou-se, com este trabalho, a elaboração e a caracterização físico-química de geleias tradicionais prebióticas mistas de jabuticaba e acerola. As formulações compostas de polpas e blends foram: F1 (75% acerola/25% jabuticaba), F2 (50% acerola/50% jabuticaba), F3 (25% acerola/75% jabuticaba), F4 (100% jabuticaba) e F5 (100% acerola) com 1,0% de pectina, 0,1% de benzoato de potássio, 3% de inulina e 40% de sacarose. Os ingredientes foram misturados e as misturas foram concentradas até atingir sólidos solúveis totais (SST) entre 65 e 68 °Brix. As geleias a partir de polpas e blends de acerola e jabuticaba indicaram teores de acidez com variação de 0,77% a 0,80%. As geleias F1 e F5, as quais possuem a maior concentração de polpa de acerola na formulação, apresentaram SST de 65 °Brix. Verificou-se que na proporção em que se aumentou a porcentagem de polpa de jabuticaba nas geleias, diminuiu-se o teor de polifenóis totais de 405,43 para 135,75 GAEg/100 g. Observou-se que à medida que se aumentou a proporção de polpa de acerola nos blends, aumentou-se também os valores de vitamina C, com destaque na polpa de acerola pura com 3704,50 mg/100 g. Quanto aos carotenoides totais, verificou-se variação de 1,63 a 4,62 mg/100 g. A geleia F4, obtida a partir de polpa e casca de jabuticaba, apresentou os maiores valores para os parâmetros de textura, exceto para coesividade. Observou-se que os teores de compostos antioxidantes preconizam um perfil nutricional às geleias. Quanto ao perfil funcional, o produto atende à legislação brasileira em vigor por conter inulina, além da presença de antioxidantes.

RESUMO Objetivo Analisar as dificuldades de fonoaudiólogos quanto à intervenção fonoaudiológica em indivíduos com doenças neurodegenerativas. Métodos Trata-se de um estudo transversal com 74 fonoaudiólogos brasileiros. Os profissionais foram convidados, por meio de redes sociais, a responder um questionário online com perguntas sobre sua atuação profissional com indivíduos com doenças neurodegenerativas. Foram incluídos apenas fonoaudiólogos que atuavam no território brasileiro e que atendiam, ou já haviam atendido, indivíduos com doenças neurodegenerativas. Para verificar a existência de associação entre aspectos da experiência dos fonoaudiólogos e as dificuldades referidas, utilizaram-se os testes estatísticos Mann-Whitney U, Qui-quadrado e Exato de Fisher. Resultados As maiores dificuldades encontradas quanto ao atendimento de indivíduos com doenças neurodegenerativas foram: dificuldade de adesão do cuidador às orientações fonoaudiológicas (52,7%), insuficiência na comunicação entre os profissionais da equipe para um cuidado interdisciplinar (52,7%) e chegada tardia para avaliação (50%). A dificuldade de adesão do paciente às orientações fonoaudiológicas (p=0,015) e a dificuldade relacionada à insuficiência na comunicação entre os profissionais para um cuidado interdisciplinar (p=0,036) foram associadas ao menor tempo de formação profissional. Já a dificuldade de adesão do cuidador às orientações fonoaudiológicas, foi associada a equipes não interdisciplinares (p=0,014). Conclusão A falta de comunicação eficiente na equipe multiprofissional, a não adesão dos cuidadores e a chegada tardia do indivíduo para avaliação fonoaudiológica, junto ao desconhecimento das possibilidades de atuação da fonoaudiologia, foram os principais obstáculos enfrentados pelos profissionais. O tempo de formação profissional foi um dos aspectos mais associados às dificuldades no trabalho de fonoaudiólogos que atendem indivíduos com doenças neurodegenerativas.

Resumen ‘Sumak Kawsay’ es una concepción que en el transcurso de los últimos años ha generado considerable interés en contextos políticos, económicos, educativos, de investigación, recibiendo atención por parte de activistas y académicos debido a la ‘ruptura’ que provoca sobre la concepción actual de orden mundial. En diferentes contextos, se asume como algo que debe ser alcanzado a través de un proceso de transformación sobre la manera en la que se construyen las representaciones sociales a nivel singular, comunitario y planetario al proponer ‘pensar de otra manera’ los conceptos de la modernidad que damos por sentados, y al promover un llamado a la restauración o invención del sentido de la experiencia, la cultura, la vida, de tal manera que pueda existir armonía y respeto con la naturaleza.

SUMMARY The present study endeavors to determine the impact of the inclusion of licuri tart in the diet of finishing lambs, Santa Inês mestizos, by evaluating the economic parameters. For this purpose, a total of 44 lambs, including both uncastrated as well as vaccinated and wormed lambs, with an average age of six months and a mean body weight of 21.2 kg ± 2.7 kg, were employed. Initially, the lambs were fed on the diet which consisted of 40% Tifton-85 hay and 60% of a concentrated mixture, mainly composed of ground corn grain, soybean meal, mineral premix, being further followed by the inclusion of the licuri cake at four different levels (a) 0.0, (b) 8.0,(c) 16.0, and (d) 24% with respect to the dry matter. Principally, the soybean meal and milled corn were replaced by the licuri cake with these levels, thereby constituting four treatments and 11 replicates (11 lambs per treatment) in a completely randomized design. Further, for subjecting the lambs to the above mentioned four different levels of treatment, the lambs were confined for 70 days. The analysis of various economic parameters revealed that upon including the licuri cake up to the level of 24%, the operation cost decreases, which in turn results in higher profitability. However, its cost at the time of use will eventually determine its use for feeding lambs, because of the possible price variations of the ingredients used to formulate the diets along with the model of production of the rural property.

Published: June 2019

Abstract This first study investigated the crustacean parasite fauna in 66 species of fish from the Matapi River basin, state of Amapá (Brazil). Fish were collected every two months between March 2012 and August 2013, encompassing dry and rainy seasons. Among the 66 species examined (corresponding to 722 fish specimens) only 11 species were parasitized. The infestation prevalence was 2.2%, and a total of 48 specimens of parasites were distributed between three different parasite groups. These included Argulus elongatus, Dolops reperta and Argulus multicolor (Branchiura), Ergasilus xinguensis and Gamidactylus sp. (Copepoda), and Isopoda (Braga patagonica), but branchiuran species were predominant. This was the first report of these parasite species for Leporinus fasciatus, Astyanax bimaculatus, Curimata incompta, Pygocentrus nattereri, Crenicichla cincta, Crenicichla johanna, Geophagus camopiensis, Pterophyllum scalare, Plagioscion squamosissimus, Hypostomus plecostomus and Propimelodus eigenmanni. Lastly, this study expands the range of occurrence of these six parasite species to the Matapi River basin in eastern Amazon.

Abstract Nematophagous fungi from the feces of water buffalo and soil from southeastern Mexico were isolated, and their in vitro predatory activity against Haemonchus contortus infective larvae (L3) (HcL3) was assessed. The fungi were isolated by sprinkling soil or feces on water agar plates. Six series of 10 Petri dishes containing a 7-day-old culture of each fungus and a series without fungi as the control were prepared. Five hundred HcL3 were added to each plate. The plates were incubated at room temperature. The average of recovered HcL3 was considered to estimate the larval reduction rate. Four nematophagous fungi isolates corresponding to Arthrobotrys oligospora, var microspora (strains 4-276, 269 and 50-80) and one identified as A. oligospora,var. oligospora (isolates 48-80) were obtained from water buffalo feces. From the soil, five isolates were isolated; three corresponded to A. musiformis (Bajío, Yumca and Macuspana isolates), and two isolates were identified as A. oligospora (Comalcalco and Jalapa de Méndez isolates). The predatory activity of isolates from water buffalo feces ranged between 85.9 and 100%. Meanwhile, the fungi from the soil ranged between 55.5 and 100% (p≤0.05). The nematophagous fungi obtained could have important implications in the control of parasites of importance in the livestock industry.

Abstract Trypanosomiasis caused by Trypanosoma evansi can seriously affect both domestic and wild animals. This article reports on an outbreak of canine trypanosomiasis on a farm in the Pantanal region of Brazil. The farm had 38 dogs, 20 of which died before receiving veterinary care. The remaining 18 dogs were underwent anamnesisn, clinical examination, hematological and biochemical evaluations. Blood smears and PCR analysis were performed for the diagnosis. The treatment protocols used according to the clinical recovery or parasitological cure of the dogs, using diminazene diaceturate, isometamidium chloride or quinapyramine sulfate. Post-treatment parasitological evaluation was performed by the microhematocrit technique. 7/18 dogs were PCR positive for T. evansi (confirmed by sequencing). There was clinical findings, which were consistent with both the acute and chronic stages of the disease in dogs. The infected dogs all exhibited at least one clinical sign of the disease. The hematological findings were compatible with trypanosomiasis, highlighting the hypochromic microcytic anemia as the main outcome. No treatment protocol was fully effective and the prolonged use of diminazene diaceturate caused the death of an animal. The trypanosomiasis can cause high rates of morbidity and mortality in dogs and difficulty in establishment an effective and safe therapeutic protocol.

Abstract The objectives of this study were to describe occurrences of Rhabditis spp. causing parasitic otitis in dairy cattle of Gir breed in the state of Espírito Santo, southeastern Brazil, and to evaluate the biological control of this nematode using the nematophagous fungi Duddingtonia flagrans (AC001) and Monacrosporium thaumasium (NF34). After nematode detection and collection, three groups were formed: two groups that were treated, respectively, with the fungal isolates; and a control group, without fungus. The treatments were as follows: (a) Petri dishes containing the culture medium 2% water agar (WA) + 250 nematodes + AC001; (b) Petri dishes containing 2% WA + 250 nematodes + NF34; and (c) Petri dishes containing only 2% WA + 250 nematodes. After seven days at 27 °C the treatments with fungi were able to capture and destroy the nematodes, with percentages of 82.0% (AC001) and 39.0% (NF34) in relation to the control group. The results demonstrate the occurrence of Rhabditis spp. after animals physical examination and that there was efficacy of the in vitro predatory activity of both fungal isolates. Thus, these results are important because they can assist in future in vivo control of this nematode in cattle.
