Authors: Boschin-Figueroa Carlos , Vargas-Rodríguez Claudio Fabián
Published: January 2020

Introducción. La boñiga líquida puede mejorar la estructura del suelo y la productividad de los cultivos, pero se necesita equipo calibrado para lograr una distribución uniforme. Objetivo. El objetivo del presente trabajo fue determinar, a nivel de campo, las combinaciones apropiadas de operación de un tanque de distribución de boñigalíquida y un tractor que lo comanda, para lograr una distribución uniforme de purines y boñiga diluida. Materiales y métodos. El experimento se realizó durante julio de 2016 en la Estación Experimental Alfredo Volio Mata de la Universidad de Costa Rica, en Ochomogo de Cartago, Costa Rica. Se utilizó un terreno de 5000 m2 arado y rastreado, donde se colocaron veinte recipientes plásticos, dispuestos en dos hileras, separados 4 m entre y dentro hileras. Se usó un tanque boñiguero acoplado a un tractor y los tratamientos fueron cuatro velocidades de desplazamiento (cuatro marchas bajas del tractor), y un grado fijo de aceleración (442 rpm). Las variables medidas fueron la capacidad y el volumen de descarga por unidad de área, y el área cubierta. Resultados. La descarga y dispersión de boñiga líquida en las diferentes marchas fue altamente significativa (p<0,01), la descarga por unidad de área fue mayor en las marchas más bajas. Se cuantificó la descarga relativa entre las diferentes velocidades de trabajo, y se fijó en 100 % la descarga mayor (marcha I) equivalente a 52 m3 ha-1, en la marcha II la descarga relativa fue de un 65 % respecto a la primera. En las marchas III y IV, los volúmenes fueron de 24 y 17 m3 ha-1, respectivamente. Conclusión. Las marchas bajas distribuyeron mayor cantidad de material por m2 favorable en cultivos más demandantes, mientras que con las marchas altas se puede cubrir más área con menor cantidad de material.

Published: January 2020

Introducción. La planta de maracuyá es importante como fruta fresca y en la agroindustria, ya que es rica en minerales y vitaminas, además, posee potencial de consumo nacional y de exportación. Se ha demostrado que el nitrógeno (N) tiene una influencia en el rendimiento de la fruta, pero no hay información sobre el rango óptimo de N para la producción máxima. Objetivo. Determinar la respuesta agronómica, fisiológica y fenológica, rendimiento y calidad de fruta en el cultivo de parchita maracuyá frente a diferentes dosis de nitrógeno. Materiales y métodos. En la Universidad Central de Venezuela, Maracay, Venezuela desde abril 2014 hasta marzo 2015 se sembraron plantas de maracuyá en un diseño completamente aleatorizado, seis repeticiones y seis plantas por unidad experimental, se evaluó un testigo (8 g N planta-1 (T1)) y tres dosis de N (100 (T2), 200 (T3) y 300 (T4) g planta-1) y una dosis de 50 y 300 g planta-1 de P2O5 y K2O, respectivamente. Las variables evaluadas fueron: altura de planta, número de hojas, tasa de fotosíntesis (A), transpiración (E), conductancia estomática (Gs), índice de clorofila (IC), contenido de N total en hoja en floración y fructificación, rendimiento y calidad de fruta. Resultados. A mayores dosis de N se obtuvieron mayores valores en altura, número de hojas, precocidad de planta, índice de clorofila, fotosíntesis neta y contenido de N foliar, y los menores valores en el T1. Las variables Gs, A y E, no presentaron diferencias significativas entre los tratamientos. Se obtuvo una reducción del rendimiento del 55 % en el tratamiento testigo, comparado con el tratamiento de 200 g de N planta-1, el cual obtuvo el mayor rendimiento. El peso promedio de fruto fue significativamente mayor en T3. Conclusión. La mejor dosis nitrogenada en plantas de maracuyá fue la de 200 g de N planta-1.

Authors: Varela-Benavides Ingrid , Trejos-Araya Carla
Published: January 2020

Introducción. El camote (Ipomoea batatas) es un cultivo muy susceptible a las enfermedades virales, las cuales se han asociado con una disminución del rendimiento del cultivo mayor al 50 %. En las plantaciones de camote costarricenses se ha reportado la presencia del virus del moteado plumoso (SPFMV), el virus del enanismo clorótico (SPCSV) y el virus del enrollamiento de la hoja (SPLCV); para el desarrollo de programas adecuados de control de estos virus, es necesaria la detección e identificación temprana mediante el uso de técnicas sensibles y eficientes. Objetivo. El objetivo de esta investigación fue estimar la incidencia del SPFMV, el SPCSV y el SPLCV en plantaciones de camote mediante qPCR. Materiales y métodos. En el 2018 se recolectaron muestras de tejido foliar de ochenta plantas con síntomas de infección viral en veinticinco plantaciones de camote distribuidas en cuatro provincias de Costa Rica. La detección de los tres virus se llevó a cabo mediante qPCR con el empleo de imprimadores y sondas de hidrólisis específicos. Resultados. En el 92 % de las plantaciones analizadas se encontró la presencia de virosis. La enfermedad viral del camote (SPVD), definida como la infección combinada del SPFMV y el SPCSV, fue la que se detectó con más frecuencia. Las plantaciones ubicadas en las localidades de Sabanilla, El Cacao y La Guácima de Alajuela fueron las únicas en presentar los tres virus estudiados. El virus SPLCV solamente fue detectado en las provincias de Limón y Alajuela. Conclusión. Es posible realizar una detección temprana de tres de los virus más frecuentes en camote con el empleo de qPCR, lo que contribuiría con los programas de producción de semilla certificada.
Aplicación del análisis bioclimático a la prescripción arquitectónica
Authors: Tendero Caballero Ricardo
Published: January 2020

La habitabilidad en la edificación es una demanda fuertemente implicada en el consumo de energía no renovable, escasa y contaminante. La reducción del consumo y la utilización de fuentes de energía sostenibles hacen necesario explorar procedimientos de análisis eficientes. Se considera el análisis bioclimático como la técnica adecuada para conseguir la optimización de la respuesta del edifico al clima, por lo que se revisan las dificultades existentes para su correcta  implantación. Mediante la revisión bibliográfica y la recopilación de iniciativas, se propone una mejora del conocimiento en campos como el aprendizaje mediante el análisis de arquitectura vernácula, la definición correcta de las condiciones climáticas locales, la determinación de los valores de consigna más apropiados para conseguir condiciones de confort interiores, la definición de los patrones de diseño, caracterización bioclimática de edificios, materiales y sistemas constructivos. Asimismo, el desarrollo de estrategias y  prácticas constructivas, la estandarización y aplicación rutinaria de métodos de comprobación “in situ” del desempeño bioclimático y la validación de los procedimientos informáticos acreditan la habitabilidad y la forma de concretar este aprendizaje en la regulación, el marco normativo y el establecimiento de condiciones de uso y mantenimiento que rentabilicen la implantación de este análisis bioclimático. Se concluye con la necesidad de aprovechar los avances conseguidos para mejorar el rendimiento de la edificación en su objetivo de conseguir una mejor habitabilidad con un menor consumo de recursos.
Life of Saint Nikephoros of Sebaze as an Illustration of the Perception of the Iconoclastic Era by the Byzantines in Later Times (Including Russian Translation of the Life)
Authors: Senina Tatyana
Published: January 2020

Introduction. This work is concerned with the perception of the iconoclastic era in the Life of St. Nikephoros of Sebaze preserved in the form of enkomion written by an anonymous author presumably in the mid 10th century, and to clarify some details of Nikephoros’ biography.

Methods. Source research and analysis, philosophical hermeneutics, comparative textological and historical research are the methods employed in this work. Sources on the subject include the edition of the Life of St. Nikephoros by F. Halkin, Lives of St. Patriarch Methodios, St. Nicetas of Medikion and St. Makarios of Pelekete, the Chronicle of Theophanes the Confessor.

Analysis. The life of St. Nikephoros written in the 10th century by a monk of the monastery of Sebaze illustrates how the iconoclastic era was seen by the next generations who no longer found living witnesses of those times. The hagiographer knows almost nothing certain about his hero, except that he was a monk, suffered for icons in the epoch of the second iconoclasm, and founded a monastery. For ordinary monks in the 10th century, the iconoclastic heresy was associated with the names of emperors Leo III, Constantine V and Leo V, which testifies to the success of the myth created by iconodules in the 9th century that the iconoclastic heresy, unlike the others, was not born in the church environment, but appeared in the imperial palace and was implanted by the authorities without much support from believers. Silence about the last iconoclast emperor Theophilos can be presumably attributed to the success of his posthumous rehabilitation. The past is completely mythologized in the Life: all bishops, priests and monks ardently struggled for their faith, enduring torment and hardship; nothing is said about the Orthodox believers who had fallen into heresy. The hero of the Life itself represented a composite character of a Christian ascetic and confessor of iconoduly completely devoid of individual traits.

Results. The analysis of the life shows that by the 10th century the iconoclastic era began to be perceived by believers – at least, by ordinary monks – as the time of epic exploits, and the knowledge of historical events became fragmentary and was based on myths and legends distributed in the church environment rather than real facts. Appendix. The article is accompanied by Russian translation of the Life of St. Nikephoros of Sebaze with a scientific commentary.
“...The Daughter of Glorious Leontius”: Historical Role and Literary Works of Aelia Eudocia Augusta in Modern Historiography (Based on Tatyana Aleksandrova’s Book “Byzantine Empress Athenais-Eudocia. Life and Works in the Context of the Reign of Emperor Theodosius II (401–450)”. Saint Petersburg, Aleteya Publ., 2018. 416 p.)
Authors: Anashkin Anton
Published: January 2020

Introduction. The article analyzes the contents of the monograph “Byzantine Empress Athenais-Eudocia. Life and Works in the Context of the Reign of Emperor Theodosius II (401–450)” by Tatyana Aleksandrova. It is devoted to the personality of Empress Eudocia (ca. 405–460) and her poetical heritage in the context of the period.

Discussion. Over the recent decades academic interest in personalities has grown significantly. And it is not only within the framework of historical science. The genre of historical research has become very popular among many Russian and Western academic researchers. Because of such attention to personalities one of the urgent tasks of modern Byzantine studies is studying works of little-known or “secondary” Byzantine authors. These ones include the personality of royal poetess Aelia Eudocia Augusta (ca. 405–460). The scale of her activity and influence on the Byzantine culture is still poorly understood.

Analysis. As a historical figure and poetess Eudocia attracted attention of researchers of Byzantine history and literature more than once. Historiography is mostly characterized by a certain duality of the approach to studying the personality and works of Eudocia. It often happens that researchers consider Eudocia the author and Eudocia the Empress as two different persons. Tatyana Alexandrova tries to combine both of these approaches and explore the poetic legacy of Eudocia in the historical and literary context of the 5th century. The author of the monograph reconstructs the biography of Eudocia, analyzes and verifies various research hypotheses of the predecessors (A. Cameron, B. Sowers, K. Holum, T. Graumann, C. Bevegni, E. Livrea, etc.). The author of the monograph comes to the conclusion that legends and myths around Eudocia’s name only remotely reflect the reality and their appearance was politically motivated. At the same time, the author studies all attributable poems and works by Eudocia and focuses attention on such ones as the Martyrdom of St. Cyprian and the Homeric centos.

Results. The author of the article comes to the conclusion that the monograph is an important step in understanding and representing the role of Eudocia in the Byzantine history and culture of the 5th century.

A narrativa heroico-nacionalista de Arthur Reis na representação da defesa da Amazônia pelos portugueses e luso-brasileiros em A Amazônia e a cobiça internacional - anos de 1960
Authors: Pacheco Alexandre
Published: January 2020

Neste texto analisaremos como a narrativa heroico-nacionalista de Arthur Reis em A Amazônia e a cobiça internacional se transformou em denúncia e ao mesmo tempo julgamento sobre o passado de cobiça dos povos estrangeiros em relação à Amazônia. Arthur Reis sistematicamente se posicionou a favor dos portugueses e dos luso-brasileiros em suas lutas para defesa da região, considerando-os como verdadeiros heróis. Neste sentido, os fatos relacionados a essas ações seriam apreendidos a partir da observação deles como dados para uma investigação histórica objetiva, que verificados e comprovados revelariam ensinamentos patrióticos para a Nação brasileira, sobretudo em relação à manutenção de nossa soberania sobre a Amazônia em meio aos anos de 1960.

El artículo se propone analizar las formas de conocimiento histórico desarrolladas en el Río de laPlata entre 1780 y 1840 teniendo en cuenta sus condiciones de producción y su sentido. Paraello se examinan los marcos conceptuales referidos a la historia, su conocimiento y representación;la progresiva toma de distancia frente a la literatura para poder constituirse en una forma deconocimiento crítico y pragmático; los usos sociales que se le daba al pasado; y algunas prácticasvinculadas al saber histórico como la edición de colecciones documentales. A lo largo de estaindagación se consideran tanto las condiciones intelectuales como políticas que afectaron laproducción de conocimiento y representaciones históricas. En ese sentido se presta especialatención a las innovaciones promovidas por los escritores ilustrados y al impacto provocado porel proceso revolucionario en la relación que se establecía con el pasado, el presente y el futuro.

Levando em consideração o surgimento de uma nova abordagem historiográfica levada adiante pelos primeiros Annales e por Fernand Braudel, o objetivo deste artigo é, a partir de La Méditerranée et le monde méditerranéen à l'époque de Philippe II e as críticas a ele endereçadas, analisar a originalidade historiográfica do mesmo, reunindo elementos que nos permitam sustentar a existência de uma concepção braudeliana de História.
Aby Warburg e a pós-vida das Pathosformeln antigas
Authors: Teixeira Felipe Charbel
Published: January 2020

O artigo analisa os conceitos de "pós-vida" da Antiguidade (das Nachleben der Antike) e de"fórmula de páthos" (Pathosformel), como pensados pelo historiador da arte e da cultura o alemão Aby Warburg (1866-1929) em seus escritos sobre o Renascimento. Argumenta-se aqui que o conceito de "pós-vida" da Antiguidade diferencia-se tanto das ideias de redespertar da Antiguidade, como pensada pelo historiador suíço Jacob Burckhardt, como de imitação dos antigos, tal qual sugerida pelo historiador da arte Johann Joachim Winckelmann, devendo ser compreendido à luz dos conceitos nietzscheanos de "apolíneo" e "dionisíaco" e da noção de Pathosformel, um neologismo do próprio Warburg. Em seguida, são discutidas algumas das formas de "pós-vida" da Antiguidade estudadas por Warburg, como o tema da Ninfa.

Tempo e crise na teoria da modernidade de Reinhart Koselleck
Authors: Duarte João De Azevedo e Dias
Published: January 2020

Este artigo explora dois aspectos constitutivos da “teoria da modernidade” proposta pelo historiador alemão Reinhart Koselleck. O primeiro corresponde à sua interpretação da emergência da noção de “tempo histórico”; e o segundo, a seu argumento acerca da crise sociopolítica que se instaura a partir da tendência moderna a recorrer a filosofias da história para sustentar programas de ação política. Procurar-se-á demonstrar que Koselleck, ao mesmo tempo em que saúda a descoberta/invenção – pelas filosofias da história do século XVIII – de uma “história humana”, condena a instrumentalização política dessas mesmas filosofias como o vetor de uma crise que se estende da Revolução Francesa até a Guerra Fria. À guisa de conclusão, sugerem-se alguns pontos de aproximação entre a visão da modernidade de Koselleck e aquela da filósofa Hannah Arendt.

Abstract Prolactin (PRL) secreting adenomas are associated with high incidence of headache. The role of hyperprolactinemia in the headache context is not clear, nor is the effect of its treatment on headache. Methods: The present longitudinal study evaluated hyperprolactinemic patients (69), in terms of presence and characteristics of headache before and after hyperprolactinemia treatment. Results: Headache was reported by 45 (65.2%) patients, independent of the etiology of hyperprolactinemia. The migraine phenotype was the most prevalent (66.6%). Medications used in the treatment of headache not changed during the study. The first line of treatment of hyperprolactinemia was dopaminergic agonists. In the last reevaluation, PRL level under treatment was within the reference range in 54.7% of the cases, and it was observed complete or partial resolution of the headache in 75% of the cases. The median PRL at this time in patients with complete headache resolution was 17 ng/mL, in those who reported partial recovery was 21 ng/mL, and in those in whom the headache did not change was 66 ng/mL, with a significant difference between the group with complete headache resolution vs. the group with unchanged headache (p=0.022). In the cases with complete headache resolution, the median fall on PRL levels was 89% and in those cases with partial headache resolution 86%, both significantly different (p<0.001) from the fall in the cases with an unchanged headache. Conclusion: Data allow us to conclude that, in this series, in the majority of cases the reduction in the level of PRL was followe3d by cessation or relief of the pain.
The neurology behind three wounded French artists during the great world war
Authors: VITTURI Bruno Kusznir , SANVITO Wilson Luiz
Published: January 2020

Abstract A unique association joins Guillaume Apollinaire, Blaise Cendrars and Louis Ferdinand Céline. Besides being great exponents of French literature, they were all neurologically wounded during the First World War. Apollinaire had a traumatic brain injury, Cendrars developed phantom limb neuropathic pain and Céline presented radial nerve paralysis. There is quite an evidence that supports that their artistic output was also influenced by acquired neurological conditions during the war. The examples of these three French authors reveal the surprising intimacy Neurology can share with art and history.
Correlação entre qualidade da água e ocorrência de diarreia e hepatite A no Distrito Federal/Brasil
Authors: Castro Rossana Santos de , Cruvinel Vanessa Resende Nogueira , Oliveira Jaime Lopes da Mota
Published: January 2020

RESUMO O abastecimento público de água de maneira segura e eficiente ainda é um desafio no Brasil. Isso pode levar a um aumento na incidência de agravos como Doença Diarreica Aguda (DDA) e hepatite A. O objetivo deste trabalho foi associar a qualidade da água distribuída e a ocorrência de DDA e hepatite A no Distrito Federal (DF) (Brasil) entre 2012 e 2017. Os dados referentes aos índices de reclamação relativos à água e da não conformidade da sua qualidade foram cedidos pela Companhia de Abastecimento do DF. As taxas de ocorrência de DDA e hepatite A foram obtidos pela Secretaria de Saúde. Os índices de reclamação tiveram relação direta com os de não conformidades na concentração de cloro residual livre e de turbidez da água; no entanto, essa relação foi inversa aos agravos. Isso mostra que o monitoramento realizado pelo controle de qualidade da concessionária teve relevância na redução desses agravos, inclusive durante o período de intermitência no abastecimento (2017). O canal de comunicação entre os usuários e o prestador de serviços, portanto, foi fundamental para as ações corretivas da empresa, o que refletiu na redução de casos de DDA e de hepatite A.
Acesso ao Saneamento básico e Incidência de Cólera: uma análise quantitativa entre 2010 e 2015
Authors: Silva Everaldo de Santana , Oliveira Deloar Duda de , Lopes Amanda Pontes
Published: January 2020

RESUMO As condições de saneamento básico são um dos principais determinantes nos índices de agravos à saúde humana, principalmente no tocante a doenças infectocontagiosas por veiculação hídrica. Dentre todas, destacamos neste trabalho a cólera: doença entérica causada pelas cepas toxigênicas do Vibrio cholerae (sorogrupos O1 e O139), que é caracterizada por um quadro de acentuada diarreia. O objetivo deste trabalho, por meio de levantamento de dados mundiais de Incidência de Cólera (IC) e percentual populacional de Acesso ao Saneamento (AS), é quantificar, evidenciar e discutir a relação entre esses dois indicadores no período de 2010 a 2015, assim como apontar outros possíveis fatores magnificantes de vulnerabilidade socioambiental para a patologia. No período analisado, foram registrados 1.575.168 casos da doença, com as maiores incidências na região do subcontinente áfrico-asiático e em países isolados nos demais continentes, como, por exemplo, Haiti (América) e Papua Nova Guiné (Oceania), que também apresentaram sérios problemas de acessibilidade a serviços de saneamento. Desta forma, apesar de sugerirmos a análise de outros fatores socioambientais, as condições de saneamento revelaram-se como um determinante expressivo para a incidência da cólera em todas as regiões do mundo.
Panorama da pesquisa sobre tratamento e reúso de efluentes da indústria de antibióticos
Authors: Rocha Antônio Carlos de Lima , Kligerman Débora Cynamon , Oliveira Jaime Lopes da Mota
Published: January 2020

RESUMO Este trabalho realizou uma revisão integrativa de artigos científicos indexados entre 2007 e 2017 em diferentes bases de dados sobre o tratamento e o reúso de efluentes provenientes da indústria de antibióticos. Foram encontrados 31 artigos, sendo que somente 4 abordaram o reúso de efluente, e 1 utilizou um sistema de tratamento em escala real. A maior parte desses estudos foi realizado na Ásia, com destaque para a China. Observa-se que, no Brasil, que é um dos grandes produtores e consumidores de fármacos do mundo, esse tipo de pesquisa ainda é incipiente. Os processos mais encontrados foram os oxidativos avançados que mostraram maior eficiência na remoção de antibióticos, mas podem gerar subprodutos, o que pode representar um risco ainda maior dependendo da substância formada. Os processos biológicos devem ser primeiramente aclimatados aos antibióticos para não serem impactados, entretanto, a liberação desses micro-organismos resistentes no corpo receptor também apresenta um risco ambiental. Os sistemas integrados de membranas ao biológico também foram bem eficientes, mas atenta-se ao risco na destinação final dessas membranas que foram capazes de reter esses compostos. No geral, são necessários mais estudos sobre essa abordagem para reduzir os riscos no desenvolvimento de micro-organismos multirresistentes no meio ambiente.

Abstract This study investigates the influence of supplier integration and lean practices on operational performance indicators: cost, quality, delivery, flexibility and speed of new products introduction. The proposed relationships are analyzed using survey data from a sample of 112 medium-sized textile companies in Brazil. The results suggest that supplier integration is significantly and positively associated with the speed of new products introduction, while lean practices are significantly and positively associated with operational performance indicators, except delivery. In addition, supplier integration does not support lean practices for any of operational performance indicators tested.

Published: January 2020

ABSTRACT Introduction: Intense physical exercise affects the balance between the production of reactive oxygen species and antioxidant defense in the muscle. Carnosine is a cytoplasmic dipeptide composed of the amino acids β-alanine and histidine. Objective: This study aimed to evaluate the effect of carnosine and its precursor β-alanine on oxidative damage caused by intense physical exercise in the soleus muscle of rats. Methods: Male Wistar rats weighing between 200 and 240 g were divided into four groups: control, exercise, exercise + β-alanine and exercise + carnosine. The animals from the groups that underwent the exercise ran on a treadmill for 60 minutes at 25 m/minute. Factors related to muscle damage and oxidative stress were assessed in soleus muscle homogenate and blood serum. Results: The exercise promoted muscle damage, as observed through increased serum activity of enzymes aspartate aminotransferase and creatine kinase. It also induced oxidative stress in soleus muscle, as seen by the increased activity of the enzymes glutathione peroxidase and glutathione reductase, decreased concentration of reduced glutathione, and increased concentration of malondialdehyde, an indicator of lipid peroxidation. Carnosine kept the creatine kinase, glutathione peroxidase and glutathione reductase enzyme activity values, and the concentration of reduced glutathione and malondialdehyde, close to those of the control group. Conclusion: The results indicate that pretreatment with carnosine protected the rat soleus muscle against oxidative damage and consequent injury caused by intense physical exercise.

ABSTRACT Introduction: Studies presenting the benefits in people with type 2 Diabetes Mellitus (T2DM) undergoing resistance training with one exercise for each muscle group, with three sets at the same intensity. Objective: To compare functional capacity and blood pressure before and after weight training. Methods: Twenty-three patients participated in a weight training program. Maximum strength and functional assessment tests were performed for the lower and upper limbs. The intervention time was 16 weeks, 12 of which consisted of training and four of evaluations. There was an increase in volume with the number of exercises and an increase in intensity with incremental weights. Results: There was significant improvement in most of the functional tests. In the 5x sit-to-stand test in the pre-training period, nine patients recorded times greater than 13.6 seconds. In the post-training period, four maintained the above time, but two reduced the time from 16.1 and 19.6 to 13.9 seconds. In the maximum load strength test there are a significant increase in both upper and lower limbs with 20.8% and 23.4%, respectively. After the training period, there was a significant reduction in systolic blood pressure both at rest and after exercise. Conclusion: The weight training program improved muscle strength, functional capacity and blood pressure in patients with type 2 diabetes mellitus.

Published: January 2020

ABSTRACT Introduction: Nandrolone decanoate is a synthetic testosterone analogue considered one of the most widely used anabolic androgenic steroids (AAS) among adolescents and athletes. Chronic ingestion of AAS increases the incidence of cardiovascular abnormalities in athletes, but the mechanism that causes these changes remains unknown. Objectives: The purpose of this study is to verify the possible effects of the use of anabolic androgenic steroids (AAS) on the morphology and oxidative metabolism of the heart in exercised and sedentary rats. Methods: This is a comparative prospective level II study. Twenty-four Wistar rats were distributed in groups that performed voluntary (TG) and sedentary (SG) running exercises, and used AAS: the Anabolic Training Group (ATG), and the Anabolic Sedentary Group (ASG). During the three months of the running protocol, the animals received an intramuscular injection of 5 mg/kg b.p. of AAS. After the training period, the rats were euthanized and the hearts were removed for evaluation of lipid peroxidation and antioxidant capacity, and for morphometric analysis. Results: The anabolic groups, ASG (0.3072 ± 0.0531) and ATG (0.2732 ± 0.0413), presented higher lipid peroxidation when compared to the non-anabolic groups SG (0.1705 ± 0.0224) and TG (0.1785 ± 0.0340). Conclusion: There was no change in total antioxidant capacity or in the thickness of the interventricular septum and left ventricular wall. Thus, the use of anabolic androgenic steroids did not cause morphological changes in the myocardium. However it did alter the oxidative metabolism. It was also verified that aerobic exercise had no protective effect against lipid peroxidation in the myocardium caused by the use of AAS. Level of evidence II; Prospective comparative study.

Published: January 2020

ABSTRACT Introduction: The increase in body fat is a natural and progressive process with aging, allowing fat infiltration in ectopic sites, such as skeletal muscle, which disrupts its function. Objective: To evaluate the association between body composition, fat infiltration into the low back multifidus muscles, and history of low back pain. Methods: This is a transversal and qualitative study that included young adult subjects of both sexes, and excluded individuals with neurological and musculoskeletal disorders and pregnant women. Fat infiltration into the multifidus and cross section area by magnetic resonance imaging; body composition by Dual-energy X-ray absorptiometry (DXA), and physical activity level determined by the International Physical Activity Questionnaire (IPAQ) were evaluated. The sample was divided by sex and. Pearson and Spearman's correlation and stepwise linear regression were performed. For this study, a p<0.05, a level of significance of 5% and confidence interval of 95% were adopted. Results: Thirty-two individuals were evaluated (59.37% women; 40.63% men). There was a correlation between fat percentage and total cross-sectional area (CSAtotal) (r=0.525; p=0.021), in women, and with lean abdominal mass (r= −0.648; p=0.017) and Body Mass Index (BMI) (r= −0.644; p=0.018) in men. There was also an association, in women, between fat percentage and cross section area (R2=0.275; p=0.021; CI=0.364 − 3.925) and, in men, with lean abdominal mass (R2=0.420; p=0.017; CI: −9.981- [-1.235]). Conclusion: There was correlation between fat percentage in the multifidus and CSA in women, and lean abdominal mass and BMI in men. There was also an association between fat percentage and cross section area in women, and lean abdominal mass in men. However, there was no evidence of any correlation between pain and low back dysfunction. Level of evidence I; Diagnostic studies - Investigating a diagnostic test.

ABSTRACT Introduction: Diabetes mellitus is accompanied by increased formation of reactive oxygen species (ROS) and decreased antioxidant capacity, leading to oxidative damage to cellular components. There is evidence to suggest that regular physical training positively changes oxidative homeostasis in the cells and tissues by lowering basal levels of oxidative damage, increasing resistance to oxidative stress. Objective: To verify the possible effects of aerobic physical training and resistance on glycemia and oxidative metabolism, and to determine whether there is any difference in outcomes resulting from different types of training in sedentary people with Type 2 Diabetes Mellitus (T2DM). Methods: A systematic review of controlled and randomized trials based on PRISMA. The databases LILACS, IBECS, Pubmed/MEDLINE, Cochrane Library, SciELO, PEDro, ScienceDirect and BIREME were searched, combining the descriptors type 2 diabetes mellitus, resistance training, aerobic exercise and oxidative stress in Portuguese, English and Spanish. The methodological quality of the papers was assessed by the PEDro scale. The data were read, analyzed, extracted and summarized. Results: Of the 1386 papers retrieved, only five met the inclusion criteria. The five selected papers, consisting of controlled and randomized clinical trials, were summarized. Conclusion: There have been many published studies reporting on exercises and diabetes. However, there is limitation when it comes to comparing their results. The variability of research methods and measurement instruments used makes it difficult to draw conclusions as to which physical training modality is most effective in reducing glycemic levels and oxidative stress in sedentary individuals with T2DM, considering that in each study analyzed in this review, the response to these variables is different. In future research, it would be important to standardize exercise modality, intensity, training time and evaluation parameters.

ABSTRACT Introduction: Physical activity (PA) remains the most important modifiable risk factor in the prevention of chronic diseases that are major killers in the modern era. However, many young people today do not meet the recommended guidelines on PA. Few studies were found on the levels of physical activity among adolescents from transitional countries. Objective: To determine the levels of physical activity in a representative sample of healthy adolescents from Pančevo (Serbia), and the factors that determine these level. Methods: This cross-sectional study included 401 randomly selected adolescents (191 boys and 210 girls) from the city of Pančevo, Serbia. The long version of the International Physical Activity Questionnaire (IPAQ), validated for Serbia, was applied. PA was expressed as metabolic equivalent-minute per week (MET-min/week) and classified as low, moderate, or high. Results: The median PA for the whole sample was 2049.18 MET-min/week. The average PA score in boys was higher (2680 MET-min/week) than in girls (1479 MET-min/week). The prevalence of respondents with inadequate PA was 53.9%, and was higher in girls than in boys. Boys showed the higher values for intense and moderate PA, while the prevalent type of PA among girls was walking. Level of PA did not depend on the adolescent's nutritional status. The most important predictors of PA among the participants were sex, father's PA, and hours spent on sedentary activities like using a computer and watching television. Conclusion: Adolescents in Pančevo do not practice enough physical activity, especially girls. Better strategies are needed, to increase levels of PA, considering the main predictors in the adolescent population. Level of Evidence II; Retrospective study.

ABSTRACT Introduction: Adipocyte volume (fat accumulation) in different parts of the body may play different roles in the metabolism and in the appearance of cardiovascular risk factors. Most studies indicate that the regional distribution of body fat seems to be more important than excess adiposity per se. High levels of physical activity are associated with lower total and visceral body fat levels. Military physical training is of paramount importance for the health and performance of soldiers in the Brazilian Army. In this context, physical evaluation will provide data on the main physical benefits involved in military tasks. Objective: Verify the relationship between visceral fat (VF), physical performance and biochemical markers of soldiers in the Brazilian Army. Methods: The sample consisted of 41 (38.9 ± 2.2 years) Brazilian male military personnel. VF was obtained with a Dual Energy X-Ray Absorptiometry densitometry device. The biochemical analysis included fasting glycemia, triglycerides (TG) and HDL-C levels. Physical performance was evaluated through two tests (12-min run and pull-ups). The Shapiro-Wilk test confirmed the normality of the variables. Pearson's correlation test was then applied, with a p-value of <0.05. Results: Significant negative correlations of VF were found with the results of both physical tests (Pull-ups r = −0.59; 12-min r = −0.61). The only biochemical variable that had a significant positive correlation with VF was TG (r = 0.44). Conclusion: The results of this study showed a significant negative association between VF and physical tests. A significant positive association between VF and TG was also found.

ABSTRACT Introduction: Evidence suggests that a higher distribution of elite athletes have birth dates in the first few months of the year. However, the advantages of birth month on performance related to starter status, structure and body composition in female futsal (5-a-side football played on a hard court, mainly indoors), are unknown. Objective: To determine the effect of relative age (ERA) on competitive female futsal athletes, and its influence on anthropometric profile and starter status. Methods: One hundred and fifteen athletes, participants in the 20th Brazilian Cup of Adult Futsal Clubs, special division, were submitted to measurements of body mass, height, skinfold thickness, body perimeters and bone diameters, in order to characterize the anthropometric profile and determine the body somatotype. The athletes were distributed in semesters and quartiles of the months of the year, according to their birth dates. Differences in the distribution of expected and observed birth dates were tested using Chi-square tests (χ2). Comparisons between semesters and birth quartiles were performed using parametric and non-parametric tests. Results: There was no ERA in distribution (p=0.248), anthropometric profile (p=0.872 to 0.912), or starter status between athletes born from January to June (p=0.352) and those born between July and December (p=0.744). On the other hand, those born in the first months of the year showed longer practice times than those born in the latter months of the year. Conclusion: Although the ERA in this study reveals longer practice times favoring female futsal athletes born in the first quartile of the year, it did not influence the starter status, the distribution in the teams, or any advantage in anthropometric profile.

ABSTRACT Introduction: Anterior cruciate ligament injury is one of the most prevalent musculoskeletal injuries. Therefore, several surgical techniques and graft types have been described for its reconstruction. Autologous hamstring tendon graft is one of the most frequently used, but use of the quadriceps tendon graft has gained prominence in recent years. Objective: To review the literature to compare the outcomes of patients undergoing anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autograft versus hamstring tendon (HT) autograft. Methods: A literature review was conducted through PubMed to locate studies (Level of evidence I-III) comparing the outcomes of the QT autograft vs. the HT autograft in patients undergoing primary ACL reconstruction. Patients were assessed on the basis of re-rupture rate, ligament instability, patient-reported outcome scores, previous pain, and isokinetic tests. Results: Six studies were selected according to inclusion criteria. A total of 481 patients were evaluated, 243 in the QT group and 238 in the HT group. The total re-rupture rate was 1.6% (8 of 481), with 6 in the HT group and 2 in the QT group, but with no statistical difference between groups. One study found increased ligament instability in the HT group and another study found greater instability in the QT group, both with statistical significance. Regarding the patient-reported functional scores, only 01 study found statistical difference, with better results in the QT group. There was no difference in previous pain between groups in the selected studies. Regarding the isokinetic test, one study found a difference in flexor force in the HT group (p <0.01), with no difference in extensor force, while another two studies found an increased extensor force deficit in the QT group within up to 01 year of follow-up. The flexor/ extensor muscle strength ratio was higher in the QT group in both studies. Conclusion: ACL reconstruction with QT graft presents re-rupture rates, ligament instability, functional scores and donor site morbidity that are similar to the HT graft, in addition to preserving greater flexor force in proportion to extensor force.

ABSTRACT The application of muscle strength training has been investigated for the development of physical capacities in sports. Although the use of training methods is quite clear, the act of prescribing the external training load is often not properly explained. Grass court, or lawn tennis, is a sport with considerable physical demands and strength training can help player performance. Thus, the aim of this study was to investigate strength training methods and external variables in training programs in competitive tennis players. Considering the findings of this particular study, we found that muscle building workout and plyometrics in combination with exercises designed specifically for the sport (tennis drills) were the most efficient muscle strength training methods for improving different strength manifestations.
