It is based on a well-known Sagnac effect which enables to detect one-axis rotational motions in a direct way and without any reference system. The presented optical fibre sensor – FOSREM allows to measure a component of rotation in a wide range of signal amplitude form 10
New Approaches to Wipe Sampling Methods for Antineoplastic and Other Hazardous Drugs in Healthcare Settings
Authors: Connor Thomas H. , Smith Jerome P.
Published: July 2016

: At the present time, the method of choice to determine surface contamination of the workplace with antineoplastic and other hazardous drugs is surface wipe sampling and subsequent sample analysis with various analytical techniques. The purpose of this article is to review current methodology for determining the level of surface contamination with hazardous drugs in healthcare settings and to discuss recent advances in this area. In addition it will provide some guidance for conducting surface wipe sampling and sample analysis for these drugs in healthcare settings.

: Published studies on the use of wipe sampling to measure hazardous chemicals, including antineoplastic drugs on surfaces were reviewed. These studies include the use of well-documented chromatographic techniques for sample analysis in addition to newly evolving technology that provides rapid analysis of specific antineoplastic drugs.

: Methodology for the analysis of surface wipe samples for hazardous drugs are reviewed, including the purposes, technical factors, sampling strategy, materials required, and limitations. The use of lateral flow immunoassay (LFIA) and fluorescence covalent microbead immunosorbent assay (FCMIA) for surface wipe sample evaluation is also discussed.

: Current recommendations are that all healthcare settings where antineoplastic and other hazardous drugs are handled include surface wipe sampling as part of a comprehensive hazardous drug-safe handling program. Surface wipe sampling may be used as a method to characterize potential occupational dermal exposure risk and to evaluate the effectiveness of implemented controls and the overall safety program. New technology, although currently limited in scope, may make wipe sampling for hazardous drugs more routine, less costly, and provide a shorter response time than classical analytical techniques now in use.
On halide derivatives of rare-earth metal(III) oxidomolybdates(VI) and -tungstates(VI)
Authors: Schleid Thomas , Hartenbach Ingo
Published: July 2016

Halide derivatives of rare-earth metal(III) oxidomolybdates(VI) have been investigated comprehensively over the last decade comprising the halogens fluorine, chlorine, and bromine. Iodide-containing compounds are so far unknown. The simple composition REXMoO4 (RE=rare-earth element, X=halogen) is realized for X=F almost throughout the complete lanthanide series as well as for yttrium. While ytterbium and lutetium do not form any fluoride derivative, for lanthanum, only a fluoride-deprived compound with the formula La3FMo4O16 is realized. Moreover, molybdenum-rich compounds with the formula REXMo2O7 are also known for yttrium and the smaller lanthanoids. For X=Cl the composition REClMoO4 is known for yttrium and the whole lanthanide series, although, four different structure types were identified. Almost the same holds for X=Br, however, only two different structure types are realized in this class of compounds. In the case of halide derivatives of rare-earth metal(III) oxidotungstates(VI) the composition REXWO4 is found for chlorides and bromides only, so far. Due to the similar size of Mo6+ and W6+ cations, the structures found for the tungstates are basically the same as for the molybdates. With the larger lanthanides, the representatives for both chloride and bromide derivates exhibit similar structural motifs as seen in the molybdates, however, the crystal structure cannot be determined reliably. In case of the smaller lanthanoids, the chloride derivatives are isostructural with the respective molybdates, although the existence ranges differ slightly. The same is true for rare-earth metal(III) bromide oxidotungstates(VI).

Clarke, AC, Anson, JM, and Pyne, DB. Proof of concept of automated collision detection technology in rugby sevens. J Strength Cond Res 31(4): 1116–1120, 2017—Developments in microsensor technology allow for automated detection of collisions in various codes of football, removing the need for time-consuming postprocessing of video footage. However, little research is available on the ability of microsensor technology to be used across various sports or genders. Game video footage was matched with microsensor-detected collisions (GPSports) in one men's (n = 12 players) and one women's (n = 12) rugby sevens match. True-positive, false-positive, and false-negative events between video and microsensor-detected collisions were used to calculate recall (ability to detect a collision) and precision (accurately identify a collision). The precision was similar between the men's and women's rugby sevens game (∼0.72; scale 0.00–1.00); however, the recall in the women's game (0.45) was less than that for the men’s game (0.69). This resulted in 45% of collisions for men and 62% of collisions for women being incorrectly labeled. Currently, the automated collision detection system in GPSports microtechnology units has only modest utility in rugby sevens, and it seems that a rugby sevens–specific algorithm is needed. Differences in measures between the men's and women's game may be a result of physical size, and strength, and physicality, as well as technical and tactical factors.
Utility of the Overhead Squat and Forward Arm Squat in Screening for Limited Ankle Dorsiflexion

Published: July 2016

Rabin, A and Kozol, Z. Utility of the overhead squat and forward arm squat in screening for limited ankle dorsiflexion. J Strength Cond Res 31(5): 1251–1258, 2017—Limited ankle dorsiflexion (DF) range of motion (ROM) has been implicated in several lower extremity disorders. Effective screening for DF ROM may, therefore, help to identify “at risk” individuals. The primary purpose of this study was to determine the utility of 2 screening tests in detecting limited ankle DF ROM. Fifty-three healthy participants underwent an overhead squat (OS) test and a forward arm squat (FAS) test, as well as bilateral testing of weight-bearing and non–weight-bearing ankle DF ROM. Participants whose DF ROM fell below 1 SD from the sample average were considered to have limited DF ROM. The sensitivity, specificity, positive, and negative likelihood ratio (LR) of the OS and FAS in detecting individuals with limited DF ROM was calculated. The sensitivity of the OS was 1.00 regardless of the mode or the side of testing, whereas specificity ranged from 0.34 to 0.36. The positive LR of the OS ranged from 1.52 to 1.56, whereas negative LR was 0.00. The sensitivity of the FAS ranged from 0.56 to 0.70, whereas specificity ranged from 0.84 to 0.88. The positive and negative LR of the FAS ranged from 3.49 to 6.02, and 0.34 to 0.53, respectively. Our findings suggest that the OS and FAS may be used as complementing tests in screening for ankle DF limitation. Because of its excellent sensitivity, the OS should be performed first, and if negative, may confidently rule out limited DF ROM. However, given a positive OS, testing should proceed with the FAS, to more confidently rule in limited DF ROM.
Theoretical and Practical Aspects of Different Cluster Set Structures: A Systematic Review
Authors: Tufano James J. , Brown Lee E. , Haff G. Gregory
Published: July 2016

Tufano, JJ, Brown, LE, and Haff, GG. Theoretical and practical aspects of different cluster set structures: a systematic review. J Strength Cond Res 31(3): 848–867, 2017—When performing a set of successive repetitions, fatigue ensues and the quality of performance during subsequent repetitions contained in the set decreases. Oftentimes, this response may be beneficial because fatigue may stimulate the neuromuscular system to adapt, resulting in a super-compensatory response. However, there are instances in which accumulated fatigue may be detrimental to training or performance adaptations (i.e., power development). In these instances, the ability to recover and maintain repetition performance would be considered essential. By providing intermittent rest between individual repetitions or groups of repetitions within a set, an athlete is able to acutely alleviate fatigue, allowing performance to remain relatively constant throughout an exercise session. Within the scientific literature, a set that includes intermittent rest between individual repetitions or groups of repetitions within a set is defined as a cluster set. Recently, cluster sets (CS) have received more attention as researchers have begun to examine the acute and chronic responses to this relatively novel set structure. However, much of the rest period terminology within the literature lacks uniformity and many authors attempt to compare largely different protocols with the same terminology. Additionally, the present body of scientific literature has mainly focused on the effects of CS on power output, leaving the effects of CS on strength and hypertrophy relatively unexplored. Therefore, the purpose of this review was to further delineate cluster set terminology, describe the acute and chronic responses of CS, and explain the need for further investigation of the effects of CS.

The adverse effects of prenatal alcohol exposure constitute a continuum of disabilities (fetal alcohol spectrum disorders [FASD]). In 1996, the Institute of Medicine established diagnostic categories delineating the spectrum but not specifying clinical criteria by which diagnoses could be assigned. In 2005, the authors published practical guidelines operationalizing the Institute of Medicine categories, allowing for standardization of FASD diagnoses in clinical settings. The purpose of the current report is to present updated diagnostic guidelines based on a thorough review of the literature and the authors’ combined expertise based on the evaluation of >10 000 children for potential FASD in clinical settings and in epidemiologic studies in conjunction with National Institute on Alcohol Abuse and Alcoholism–funded studies, the Collaborative Initiative on Fetal Alcohol Spectrum Disorders, and the Collaboration on FASD Prevalence. The guidelines were formulated through conference calls and meetings held at National Institute on Alcohol Abuse and Alcoholism offices in Rockville, MD. Specific areas addressed include the following: precise definition of documented prenatal alcohol exposure; neurobehavioral criteria for diagnosis of fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder; revised diagnostic criteria for alcohol-related birth defects; an updated comprehensive research dysmorphology scoring system; and a new lip/philtrum guide for the white population, incorporating a 45-degree view. The guidelines reflect consensus among a large and experienced cadre of FASD investigators in the fields of dysmorphology, epidemiology, neurology, psychology, developmental/behavioral pediatrics, and educational diagnostics. Their improved clarity and specificity will guide clinicians in accurate diagnosis of infants and children prenatally exposed to alcohol.

Mammals stand out among the main game animals of the world, being exploited by human beings for different ends, and being important for the subsistence of several communities. In semiarid environments, as in the Brazilian Caatinga biome, wild mammals have been exploited by the local human population, including endangered species. In this scenario, beyond biological research of the exploited animals, ethnozoological studies are important for supporting plans for the sustainable management and conservation strategies for the mammalian fauna of the semiarid landscape. This study aims to contribute to new research into the ethnomammalogy of this specific region. It provides a catalogue of the mammals and their ethnozoological importance, including a brief characterization of game mammals of the morphoclimatic domain of the Caatinga. The results show that at least 41 species of wild mammals interact with the population that lives in the semiarid region, as sources of products that can be used for the following purposes: food (31 species), medicinal (38 species), ornamental or decorative purposes (23 species), in magical/religious practices (31 species), and as pets (24 species). Twenty-five species are hunted because of concerns over personal safety or predation on livestock and pests. Among the recorded mammals, 13 (31.7%) are listed in some threatened category (Critically endangered, Endangered or Vulnerable). Hunting is one of the main factors contributing to this situation, which provides evidence that conservation strategies should consider the associated human needs, integrating cultural aspects of the local populations, and ecological aspects associated with the biodiversity of the region.

Competencias de directores académicos en instituciones de educación superior: Un estudio en el sureste de México
Authors: Patrón-Cortés Roger Manuel
Published: July 2016

Este trabajo presenta aspectos críticos relacionados con la formación de directores académicos de una institución de educación superior ubicada en el sureste de México. Asimismo, tiene como objetivo identificar las competencias que utilizan y las que necesitan adquirir con miras a mejorar la eficacia y productividad escolar. El estudio es de corte cualitativo y emplea como método un estudio de campo basado en cuatro casos seleccionados. Se incluyen observaciones, entrevistas y análisis de documentación. Los resultados indican que existen diferencias entre conocimientos y competencias, pues aunque los directores tienen la preparación que les permite estudiar y comprender aspectos relacionados con la educación superior, se les dificulta al momento de aplicarlos. Los directores manejan más las competencias requeridas para el logro de resultados y la unidad interna de la institución, y usan menos las que se refieren a la relación eficaz de la persona consigo misma y con el entorno. En términos generales, los directores requieren adquirir y desarrollar competencias principalmente en las áreas del comportamiento humano, tales como red de relaciones efectivas, negociación, comunicación, empatía, y trabajo en equipo, entre otras. En este sentido, los directores necesitan desarrollar relaciones humanas efectivas tanto con la comunidad escolar como con personas clave del entorno externo para mejora de la eficacia y productividad de la institución.

Authors: Chiguay López María Soledad , Villagra Bravo Carolina Pilar
Published: July 2016

En este artículo se comparten los resultados de una evaluación interna, realizada para mejorar la gestión directiva en una Escuela de Educación Especial, empleando un instrumento de evaluación basado en el Marco para la Buena Dirección en su dimensión de Liderazgo; documento publicado por el Ministerio de Educación de Chile (2005). Se analiza que los participantes de este proceso evaluativo presentan similitudes en sus valoraciones del desempeño directivo, todas ellas referidas a la necesidad de evidenciar cambios dentro del contexto escolar, relacionados con la optimización de los canales de comunicación, la administración oportuna de conflictos, así también el uso de información para nutrir el proyecto educativo institucional con el propósito de fortalecer la participación de la comunidad educativa. La oportunidad de analizar estos resultados de la evaluación ascendente, propician la reflexión crítica del desempeño de quien dirige la institución. Lo anterior, facilita a la directora liderar procesos de mejoramiento considerando la visión del equipo pedagógico de la escuela. Finalmente, se destaca de la experiencia, la alta valoración que manifiestan los participantes sobre la modalidad de evaluación desarrollada, dado que se ejemplifica sobre la importancia de la reflexión de la propia práctica para iniciar procesos de mejora, con lo cual se espera comprometer al profesorado desde una visión diferente de la evaluación.

Analítica de datos de aprendizaje (ADA) y gestión educativa
Authors: Aristizabal F Jorge Alexánder
Published: July 2016

Este artículo surge como una derivación del marco teórico, metodológico y avances del proyecto de tesis doctoral del autor sobre minería de datos educativos en un aula presencial, teniendo como variables las actividades de enseñanza, el enganchamiento estudiantil y la evaluación del aprendizaje. La idea central se basa en el hecho de que las instituciones educativas cuentan con una gran variedad de datos e información provenientes de sistemas de información escolar, tales como resultados de evaluaciones internas o externas, asistencia a clases, nivel socioeconómico, esquemas de alimentación, llegadas tarde, desempeño año por año, entre otros, los cuales, de acuerdo con las tendencias mundiales, son insumos importantes para la toma de decisiones informadas. No obstante, muchas veces esta información queda acumulada o almacenada en algún lugar de la institución sin que se le dé uso efectivo a esta, o peor aún, la gran cantidad de información del día a día no se recopila o registra, perdiendo así un gran potencial para mejoras académicas. El presente trabajo tiene como objetivo presentar unos conceptos generales acerca de la analítica de datos en el contexto escolar y cómo este proceso puede contribuir a la gestión educativa, principalmente para la toma de decisiones informadas y el desarrollo de planes de acción.

Authors: Barthel Lennart
Published: July 2016

This article was migrated. The article was not marked as recommended. Surgical clerkship is essential for medical students to gain practical knowledge and insight into a toughly organized clinical environment. Usually, it is applied to the students themselves to find their place in the team and to take on tasks, whereby the clerkship can give satisfaction and success. For many students, however, this is difficult to implement, and in case of failure, the learning outcome deteriorates and consequently negatively affects the desire to pursue a career in surgery. This article is written for medical students with a view to offer twelve tips to gain valuation from their surgical clerkship based on personal experience, exchange of views with colleagues, and a review of literature.

Published: July 2016

ABSTRACT Postural instability and axial rigidity are frequent symptoms of the Parkinson’s disease (PD). Objective Correlate the occurrence of falls and the activity of rolling over in bed with performance on the Trunk Mobility Scale (TMS) in patients with PD, and determine whether this instrument score can predict the risk of falls. Method This is a cross-sectional study. Assessed patients reported the frequency of falls in the previous year and whether they had difficulties rolling over in bed. Then, the following scales were applied: TMS, Hoehn and Yahr, Unified Parkinson’s Disease Rating Scale-III and Schwab and England Activities of Daily Living. Results Eighty-five patients were analyzed. Patients with a history of falling showed worse performance in the TMS (p < 0.01). There is a significant correlation between TMS and the activity of rolling over in bed (p < 0.01). Conclusion PD fallers present worse scores in TMS, and there is a significant correlation between difficulty rolling over in bed and TMS score.

Published: July 2016

ABSTRACT Mild impairment in activities of daily living (ADL) can occur in Mild Cognitive Impairment (MCI), but the nature and extent of these difficulties need to be further explored. The Canadian occupational performance measure (COPM) is one of the few individualized scales designed to identify self-perceived difficulties in ADL. The present study investigated impairments in ADL using the COPM in elderly with MCI. A total of 58 MCI patients were submitted to the COPM for studies of its validity and reliability. The COPM proved a valid and consistent instrument for evaluating ADL in elderly MCI patients. A total of 74.6% of the MCI patients reported difficulties in ADL. Of these problems, 41.2% involved self-care, 31.4% productivity and 27.4% leisure. This data further corroborates recent reports of possible functional impairment in complex ADL in MCI.

Published: July 2016

ABSTRACT Cerebral hemispheres, although similar, are neither completely symmetrical in structure nor equivalent in function. EEG asymmetry studies have been directed more to frequency than to amplitude analysis. Objective Better definition of normal amplitude asymmetry values on the classical EEG frequency bands. Results EEG amplitude asymmetry index (AAI) is physiologically low in normal adults, differences usually lesser than 7%. Conclusion Persistent or intermittent amplitude asymmetry regional differences higher than 7% may be suggestive of pathology after adequate correlation with clinical data and EEG classical visual analysis.

Published: July 2016

Abstract The aim of this research is to present a comparative analysis between theoretical and experimental thermal fields as well as a microstructural behaviour and residual stresses applying multiple weld beads in the joint of two API 5L X52 pipe sections. The thermal field, microstructural and residual stresses were numerically modelled through the finite element method (FEM) and compared to experimentally. The simulation conditions used in the FEM analysis were similar considerations to the underwater welding conditions. The finite element analysis was carried out, first by a non-linear transient thermal analysis for obtaining the global temperature history generated during the underwater welding process. Subsequently, a microstructural behaviour was determined using the temperatures distribution obtained in the pipe material by calculating the structural transformations of the material during the welding process, and finally a stress analysis was developed using the temperatures obtained from the thermal analysis. It was found that this simulation method can be used efficiently to determinate with accuracy the optimum welding parameters of this kind of weld applications.

L'adolescent, la différence et le lien social
Authors: Stitou Rajaa
Published: July 2016

L’auteur montre que si l’adolescent questionne autant la famille et la civilisation moderne dans leur rapport aux idéaux, c’est parce qu’à travers lui se repose avec acuité la question de la différence, interpellant l’autre au cœur de ce qui le fonde et le divise, à la croisée du singulier et du collectif. Cette différence qui se ravive à travers l’épreuve de grandir et qui s’exacerbe dans le contexte de l’immigration peut être constructive lorsqu’elle est reconnue comme porteuse d’altérité. Mais elle peut déboucher sur la ruine lorsqu’elle est perçue comme une menace et qu’elle n’est plus entourée par des repères symboliques. C’est ce dont témoigne l’expérience clinique au quotidien auprès d’un bon nombre d’ adolescents dit en rupture de lien social, qui finissent par se confondre avec l’image déficitaire que leur renvoi d’eux même l’Autre Social et/ou parental.
O ideal da consolação e a paixão pela morte
Authors: Silva Paulo José Carvalho da
Published: July 2016

A arte de consolar alguém que sofre tem uma longa história. Alguns pensadores tornaram-se uma referência fundamental no Ocidente e seus escritos exerceram importante influência, sobretudo na tradição da medicina da alma. É o caso de Sêneca, herdeiro inovador do estoicismo antigo, que escreveu a Consolação a Márcia (Ad Marciam de Consolatione) entre os anos 37 e 41, na Roma sob o governo de Calígula. Essa carta pública endereçada a uma nobre dama romana que perdera um filho é considerada a obra mais antiga conhecida e datada desse homem político e pensador, nascido em Córdova, no ano 4 a.C e morto no ano 65, e é, sem dúvida, um texto de grande interesse para a compreensão da antiga prática da consolação.

La mayoría de los sujetos participantes consideran que el empuje depende la posición del objeto sumergido.
Recent advances in food allergy
Authors: Alcocer Marcos Julio Caruso , Ares Silvia de la Cruz , López-Calleja Inés
Published: July 2016

Summary Food allergy is a public health issue that has significantly increased worldwide in the past decade, affecting consumers’ quality of life and making increasing demands on health service resources. Despite recent advances in many areas of diagnosis and treatment, our general knowledge of the basic mechanisms of the disease remain limited i.e., not at pace with the exponential number of new cases and the explosion of new technologies. Many important key questions remain: What defines a major allergen? Why do some individuals develop food allergies and others do not? Which are the environmental factors? Could the environmental factors be monitored through epigenetics or modified by changes in the microbiome? Can tolerance to food be induced? Why are some foods more likely to trigger allergies than others? Does the route and timing of exposure have any role on sensitization? These and many other related questions remain unanswered. In this short review some of these topics are addressed in the light of recent advances in the area.

Resumo A determinação de impurezas do café torrado e moído faz parte das análises que contribuem para assegurar o controle da qualidade do produto. O objetivo deste trabalho foi validar o procedimento metodológico de microscopia para detecção e quantificação das impurezas cascas e paus em café torrado e moído. O método baseou-se no princípio da extração de gordura do café com solvente orgânico, eliminação do pó fino por peneiração e determinação por catação pelo uso de microscópio estereoscópico. Setenta amostras de café torrado e moído coletadas em estabelecimentos comerciais de Belo Horizonte, MG, tiveram as análises duplicadas por três analistas, totalizando 420 determinações, com os resultados expressos em porcentagens das impurezas cascas e paus. Os coeficientes de variação em condições de repetibilidade variaram de 7,0% a 27,9%, sendo considerados satisfatórios para microscopia. O fator analista tem forte influência nos parâmetros de precisão e exatidão do método. O método mostrou-se preciso a partir da concentração de 0,2% de impurezas. A exatidão do método foi satisfatória com a recuperação estando numa faixa aceitável. As incertezas variaram com a faixa de concentração de impurezas e tenderam a ser inversamente proporcionais. O método foi considerado adequado para análise destas impurezas do café torrado e moído e tem potencial para ser indicado nos procedimentos de fiscalização.
Mise-en-film da fotografia em três documentários brasileiros

Resumo Este artigo busca analisar, em três filmes da cinematografia brasileira recente, os modos como a fotografia, entendida como dispositivo de rememoração, é colocada em cena, compreendendo-a como rastro da presença de algo que já se tornou ausente. Pretende-se discutir como, ao solicitar imagens retiradas dos "álbuns de família", corrobora-se a construção de narrativas que dão a ver a biografia de homens e mulheres comuns, reais ou imaginados pelo documentário. Verificar, em metodologias distintas, o exercício político e estético do fazer cinematográfico que expõe as fragilidades e possíveis frustrações na reconstrução de algo longínquo (do ponto de vista do personagem) e desconhecido (do ponto de vista dos autores), por mais presente materialmente que esteja a imagem no ato da rememoração.

ABSTRACT Jatropha curcas L. is a plant species with many potential applications, especially medicinal uses (hypoglycemic, anti-inflammatory, haemostatic, healing, anti-tumor). The objective of this study was to test germination in moist paper rolls for whole seeds and in vitro for excised embryonic axes, in an attempt to identify the best method to assess the quality of J. curcas seed germplasm, cryopreserved with different water contents. The experimental sample with a 6.2% moisture content (MC) was divided in subsamples which were hydrated and dehydrated for 0 (control), 4, 8, 11 and 24h. The initial germination percentages were 63% for whole seeds and 81% for excised embryonic axes. After exposure to liquid nitrogen (LN), germination percentages were 48% (whole seeds) and 57% (excised embryonic axes). There was no significant difference between germination percentages in embryonic excised from seeds subjected or not subjected to freezing, with different MC. In contrast, there was a reduction of the whole seed germination percentage when exposed to LN (contrast = 0.17, standard error = 0.04, t = 4.09, p = 0.001) and not for the hydration and dehydration treatments. The methodology based on in vitro cultures of the embryonic axis isolated from seeds stored in LN with distinct MC values was more efficient than the standard germination test to evaluate the viability of J. curcas seeds before and after LN storage.

RESUMO O maracujá-amarelo (Passiflora edulis f. flavicarpa Deg) é considerado um alimento funcional, visto que, além de funções nutricionais, desempenha ações em vias metabólicas específicas. A farinha da casca do maracujá-amarelo (Passiflora edulis f. flavicarpa Deg) é rica em pectina. Esta fibra reduz a absorção de glicídios e lipídios, influenciando no metabolismo destes nutrientes. Portadores de patologias associadas às alterações no metabolismo glicêmico e lipidêmico têm utilizado este recurso de forma indiscriminada. Porém, substâncias designadas glicosídeos cianogênicos, presentes na casca do fruto são tóxicas ao organismo e prejudiciais à saúde. Ademais, o uso exacerbado de agrotóxicos na produção do maracujá é preocupante e a ingestão destes compostos também pode acarretar complicações à saúde. Portanto, o objetivo do presente trabalho foi sintetizar o conhecimento disponível referente aos efeitos terapêuticos e colaterais da suplementação com a farinha da casca do maracujá-amarelo (Passiflora edulis f. flavicarpa Deg). Foi realizada uma revisão bibliográfica nas bases de dados indexadas SCIELO, LILACS e PUBMED, sem limitação quanto ao período de publicação. Os estudos inclusos no trabalho, de forma unânime, apresentam eficácia da suplementação com a farinha da casca do maracujá-amarelo. A trituração da casca do fruto, realizada no processo de obtenção da farinha, é incapaz de promover redução de glicosídeos cianogênicos e agrotóxicos, permitindo que os indivíduos submetidos à suplementação estejam susceptíveis aos efeitos tóxicos destes compostos. Dessa forma, o desenvolvimento de estudos que avaliem a toxicidade da suplementação por períodos crônicos é de suma importância. Referente ao uso de agrotóxicos, a produção da farinha com frutos orgânicos pode ser uma alternativa para atenuar a toxicidade, sendo necessária a elucidação desta hipótese através de estudos.
As "visões" de Tirésias: arte, música e compreensão
Authors: Trombetta Gerson Luís
Published: July 2016

Resumo: O artigo analisa as relações possíveis entre os sistemas simbólicos da arte e da ciência. Ainda que existam especificidades em cada uma dessas expressões do pensamento humano, ambas são experiências de compreensão do mundo e portadoras de conteúdos de verdade. O artigo segue a posição construtivista de Nelson Goodman, que recusa qualquer hierarquia entre as formas de conhecimento. Os traços gerais de sua epistemologia demonstram o valor cognitivo da arte e da música, recusando a noção de que experiências com elas sejam apenas prática de "habilidades" ou ocasiões "emocionais".
Adorno, Hanslick e a questão da autonomia estética da música
Authors: Videira Mário
Published: July 2016

Resumo: No semestre de inverno de 1932/33, Theodor Adorno ministrou na Universidade de Frankfurt um curso sobre o ensaio Do Belo Musical. Num artigo publicado alguns anos mais tarde, Adorno enfatizava a importância desse livro, uma vez que ele fixava o elemento da lógica imanente da composição musical, contra os autores que defendiam a música programática. Com efeito, um dos principais objetivos do ensaio de Hanslick era o estabelecimento da autonomia da obra musical. De acordo com ele, o belo na música é algo especificamente musical consistindo apenas e tão somente nos próprios sons e em sua combinação artística. Embora as referências diretas a Hanslick sejam relativamente raras e esparsas nos textos de Adorno, não devemos subestimar suas ressonâncias no pensamento desse autor. O objetivo desse artigo é investigar em que medida as ideias de Hanslick acerca da autonomia estética da música poderiam ter influenciado o conceito adorniano de material musical, bem como a sua abordagem da análise musical.

Abstract: The distribution of cells involved in the immune response in accessory sex glands of rams experimentally infected with Actinobacillus seminis was studied. Twelve one-year old rams were experimentally infected by intraurethral (IU) (n=4) and intraepididymal (IE) (n=4) route, and four control (CON) animals were used. The animals were slaughtered 35 days post-inoculation, samples were taken from accessory sex glands, and bacteriology and histopathology tests were performed. The presence of CD4, CD8 and TCRγδ (WC1) lymphocytes, CD45RO cells, macrophages (CD14), dendritic cells (CD1b), IgA-, IgG- and IgM-containing cells (IgCC) was determined. Animals of the IE group developed clinical epididymitis. No lesions were seen in rams of the IU group; two of the intraepididymal inoculated CON developed small lesions in the epididymis. A. seminis isolates were achieved from 6:16 (37.5%) accessory sex glands in the IE group, but not in the IU and CON groups. In the CON group, IgA- and IgM- containing cells predominated in the bulbourethral glands and the disseminated prostate, and they were scarce or null in the vesicles and ampullae. A significant increase of IgA-, IgG- and IgM- containing cells was confirmed in the seminal vesicles, the ampullae and the bulbourethral glands in the IE group. In the IE and IU groups, an increase in CD4, CD8, WC1, CD45RO and CD14 was evidenced in the vesicles and ampullae. CD1b dendritic cells were present in the ampullae and vesicles with inflammatory processes. A. seminis triggered a local immune response in the IE and IU groups. These results indicate a different pattern of infiltrating immune cells in the accessory sex glands of infected A. seminis rams.

Abstract: An outbreak of Brachiaria decumbens poisoning in goats in the state of Mato Grosso do Sul, Brazil, is described. Out of a herd of about 1,000 goats, seven goats died after showing photosensitivity (3 out 7 goats) and icterus (4/7). Other clinical signs included lethargy, dehydration and weight loss (7/7). At necropsy there was either hepatomegaly or liver atrophy; orange, yellow or gray discoloration - were observed in the liver of six goats. Two had accentuation of lobular pattern and punctate, linear or stellar fibrous depressions were randomly distributedover the capsular surface. Macroscopic changesattributedto liver failure consisting of hydropericardium (2/7) and ascites (2/7) were observed. Histologically, there was accumulation of refringent crystals in the bile ducts and infiltration of foamy macrophages in the liver of all goats. Foamy macrophages were also present in the hepatic and mesenteric lymph nodes of two goats. The diagnosis of B. decumbens poisoning was based on epidemiology, clinical signs, necropsy findings and histopathology.
