Abstract The following work presents the first study applying the passive acoustic monitoring of anurans at lotic environments for a long time. This study aims to test the efficiency of the passive acoustic monitoring method and active monitoring in detecting anurans in lotic environments of Itinguçu State Park. Specifically, we tested whether species richness differs when comparing active and passive monitoring surveys. Therefore, this study aims to test the efficiency of the passive acoustic monitoring method and active monitoring in detecting anurans in lotic environments of the Itinguçu State Park. The passive acoustic monitoring period was 72 uninterrupted hours at each collection point with intervals of 45 days. Finally, species richness was calculated, and the efficiency of the methods was compared in different scenarios. Our results demonstrated that the park has species that vocalize day and night, but most at night, there is overlapping acoustic niche; waterfall environments harm the quality of recordings; and in lotic environments the active monitoring method was more efficient than the passive acoustic monitoring in all sampling scales. Although the passive acoustic monitoring was not as efficient in a low temporal scale, it tends to increase in efficiency with longer sampling duration. time Park Specifically surveys Therefore 7 4 days Finally calculated scenarios night niche recordings scales scale duration

Introduction: Papillary carcinomas are the most prevalent and least aggressive thyroid carcinomas (PTC). In some cases, the diagnosis is doubtfull and the prognosis is poor. The search for tissue biomarkers that ensure both the diagnosis for indeterminate cases and the prognosis, identifying the most aggressive cases, has been studied in recent decades. Objective: To review the literature in search of cyclin D1 as a marker of papillary thyroid carcinomas and multinodular goiters and evaluate whether its expression correlates with the clinicopathological characteristics of papillary thyroid carcinomas. Methods: Narrative review carried out by collecting information for reading and analysis from online research on virtual platforms. Initially, a search was carried out from MESH descriptors related to the topic, using the following terms: “papillary thyroid carcinoma, cyclin D1, immunohistochemistry, diagnosis, prognosis.” with AND or OR search, considering the title and/or abstract and those chosen were read in full. Results: The search included 77 articles that were compiled in this review. Conclusion: Cyclin D1 was expressed in the vast majority of PTCs, with diffuse distribution being predominant. There was no correlation between its expression and any clinicopathological characteristic of PTC.

Racional - Os carcinomas papilíferos são os mais prevalentes e menos agressivos de tireoide (CPT). Em alguns casos, o diagnóstico é duvidoso e o prognóstico ruim. A busca de biomarcadores teciduais que permitam assegurar tanto o diagnóstico para casos indeterminados, quanto o prognóstico, identificando os casos de maior agressividade, têm sido estudadas nas últimas décadas. Objetivo: Revisar na literatura na busca da ciclina D1 como marcador dos carcinomas papilíferos de tireoide e nos bócios multinodulares, e avaliar se a expressão dela apresenta correlação com as características clínico-patológicas dos carcinomas papilíferos de tireoide. Métodos: Revisão narrativa feita colhendo informações para leitura e análise a partir de pesquisa online em platoformas virtuais. Inicialmente foi realizada busca por descritores DECs relacionados ao tema, utilizando os seguintes termos: “carcinoma papilífero de tireoide, ciclina D1, imunoistoquímica, diagnóstico, prognóstico.” com busca AND ou OR, considerando o título e/ou resumo e os escolhidos foram lidos na íntegra. Resultados: A busca incluiu 77 artigos que foram compilados nesta revisão.  Conclusão: A ciclina D1 foi expressa na grande maioria dos CPT sendo a distribuição difusa predominante. Não houve correlação entre a expressão dela com qualquer característica clinicopatológica dos CPT.

Resumen: Durante la adolescencia, las funciones ejecutivas frías y calientes aún se están desarrollando, lo que hace importante evaluar e intervenir si hay cambios. El presente estudio tiene como objetivo identificar, a través de una revisión sistemática, qué intervenciones en funciones ejecutivas han sido estudiadas en adolescentes típicos, se incluyen funciones ejecutivas calientes y frías, y se busca identificar los efectos de estas intervenciones en dicha población. La búsqueda se realizó según el método PRISMA en la base de datos PubMed. De los 315 estudios hallados inicialmente, solo cinco artículos pasaron los criterios de exclusión y el análisis por parte de los jueces. Los estudios seleccionados revelaron un mayor efecto de las intervenciones sobre las funciones ejecutivas frías que sobre las calientes; lo que puede corroborar datos previos que sugieren que las funciones ejecutivas calientes tardan más en estimularse que las frías. Solo uno de los cinco estudios estimuló conjuntamente las funciones ejecutivas frías y calientes, lo que revela la necesidad de más investigación en el área. El pequeño número de artículos seleccionados, a pesar de limitar las conclusiones, refuerza la necesidad de realizar más investigaciones sobre la intervención en funciones ejecutivas frías y calientes en adolescentes con desarrollo típico.

Abstract: During adolescence, hot and cold executive functions are still developing, making it essential to assess and intervene if changes occur. The present study aims to identify, through a systematic review, which interventions in executive functions have been studied in typical adolescents, including hot and cold executive functions, seeking to determine the effects of these interventions in this segment. The search was conducted according to the PRISMA method in the PubMed database. Of the 315 articles initially located, five remained after applying exclusion criteria and analyzing by judges. The selected articles revealed a more significant effect of interventions on cold executive functions than hot ones, which may corroborate previous data suggesting that hot executive functions take longer to be stimulated than cold ones. Only one of the five articles jointly stimulated cold and hot executive functions, which reveals the need for more research in the area. The small number of articles selected, despite limiting the conclusions, reinforces the need to conduct more research on intervention in hot and cold executive functions in typically developing adolescents.

Resumo: Durante a adolescência, as funções executivas frias e quentes estão ainda em desenvolvimento, o que torna importante avaliar e intervir caso haja alterações. O presente estudo tem como objetivo identificar, por meio de uma revisão sistemática, quais as intervenções em funções executivas vêm sendo estudadas em adolescentes típicos, incluindo funções executivas quentes e frias, buscando identificar os efeitos dessas intervenções nessa população. A busca foi conduzida de acordo com o método PRISMA na base PubMed. Dos 315 estudos inicialmente localizados, cinco artigos restaram após aplicação de critérios de exclusão e análise de juízes. Os estudos selecionados revelaram maior efeito das intervenções sobre funções executivas frias do que sobre as quentes, o que pode corroborar dados anteriores que sugerem que as funções executivas quentes demandam mais tempo para serem estimuladas do que as frias. Apenas um dos cinco estudos estimulou conjuntamente funções executivas frias e quentes, o que revela necessidade de mais pesquisas na área. O pequeno número de artigos selecionados, apesar de limitar as conclusões, reforça a necessidade de condução de mais pesquisas sobre intervenção em funções executivas quentes e frias em adolescentes com desenvolvimento típico.

Abstract: The concept of dignified death or a good death has been widespread among health professionals, who routinely deal with it and experience the ethical dilemma about what should really be done in the face of a terminally ill patient. Given this, the present study aims to show the concepts and how cases of terminally ill patients have been conducted within the Intensive Care Units (ICU). To argue about the application and functionality of euthanasia, orthothanasia and dysthanasia in ICUs, a literature review of 14 articles was carried out. It was concluded that the knowledge that the professional has in relation to these themes needs to be taken into account and to distinguish the specific theme that is addressed, not forgetting to emphasize the rights provided for in the constitution and the well-being of the paciente and his family.

Resumen: El concepto de “muerte digna” o “buena muerte” ha sido muy difundido entre los profesionales de la salud, que lo manejan de manera rutinaria y experimentan el dilema ético sobre lo que realmente se debe hacer ante un enfermo terminal. Ante esto, el presente estudio tiene como objetivo mostrar los conceptos y cómo los casos de pacientes terminales han sido tratados dentro de las Unidad de Cuidados Intensivos (UCI). Para argumentar respecto de la aplicación y funcionalidad de la eutanasia, la ortotanasia y la distanasia en las UCI, se realizó una revisión bibliográfica de 14 artículos. Se concluyó que se debe considerar el conocimiento del profesional con relación a estos temas y distinguir el tema específico que se aborda, sin olvidar enfatizar los derechos previstos en la Constitución y el bienestar del paciente y su familia.

Resumo: O conceito de morte digna ou boa morte tem sido difundido entre os profissionais de saúde, os quais lidam com isso rotineiramente e vivem o dilema ético sobre o que realmente deve ser feito diante de um paciente terminal. Visto isso, o presente estudo visa mostrar os conceito e como tem sido conduzido os casos de pacientes em fase terminal dentro das Unidades de Terapia Intensiva (UTI). Para argumentar sobre a aplicação e a funcionalidade da eutanasia, ortotanásia e distanásia nas UTIs foi realizada uma revisão bibliográfica de 14 artigos. Concluiu-se que precisa ser levado em consideração o conhecimento que o profissional tem em relação a esses temas e distinguir a temática específica que é tratado, não esquecendo de salientar os direitos previstos na constituição e o bem-estar do paciente e de sua família.

Abstract: The use of imagem strategies in medical socieal networks is increasingly widespread, meeting the ethical limit established by the CEM. Knowing this, the present study sought to understand the problem of patient exposure in medical social networks. For this, a literature review was carried out from the Scientific Electronic Library Online (Scielo), Pubmed, UpToDate, LILACS databases, articles in English, Spanish and Portuguese published from 2018 onwards were included. Thus, a tendency was noticed in some cities to create laws to regulate this exposure, given that the use of images has become routine in medical advertising, as a way to demonstrate results. However, this practice is greatly accompanied by ethical failures as recommended by the CFM.

Resumen: El uso de estrategias de imagen en las redes sociales médicas está cada vez más extendido, cumpliendo el límite ético establecido por el CEM. Sabiendo esto, el presente estudio buscó comprender el problema de la exposición de los pacientes en las redes sociales médicas. Para ello, se realizó una revisión bibliográfica a partir de las bases Scientific Electronic Library Online (Scielo), PubMED, UpToDate, LILACS, incluyendo artículos en inglés, español y portugués publicados a partir de 2018. Así, se percibió en algunas ciudades la tendencia a crear leyes para regular esta exposición, dado que el uso de imágenes se ha vuelto rutinario en la publicidad médica, como una forma de demostrar resultados. Sin embargo, esta práctica está muy acompañada de faltas éticas como recomienda el CFM.

Resumo: A utilização das estratégias de imagem nas redes sociais médicas está cada vez mais disseminada, encontrando-se no limite ético estabelecido pelo CEM. Sabendo disso, o presente estudo buscou entender a problemática da exposição do paciente nas redes sociais médicas. Para isso, foi feita uma revisão da literatura a partir das bases Scientific Eletronic Library Online (Scielo), PubMED, UpToDate, LILACS, foram incluídos artigos em inglês, espanhol e português publicados a partir de 2018. Assim, percebeu-se em algumas cidades a tendência de criar leis para regular essa exposição, haja vista que a utilização de imagens tornou-se rotineira na propaganda médica, como forma demonstrar resultados. Todavia, tal prática vem acompanhada grandemente de falhas éticas segundo o preconizado pelo CFM.

Pyricularia oryzae Triticum (PoT) is known to survive in wheat seeds and this condition favors its spread. There are, however, many gaps in knowledge regarding the damage caused by this pathogen in relation to the establishment and sanity of wheat seedlings. The objective of this study was to determine whether there is a correlation between incidence of PoT in wheat seeds and variables associated with the establishment and the sanity of the produced seedlings. Seven samples of wheat seeds naturally infected with the pathogen were used. The incidence of PoT in each of the seed samples was determined via the Blotter test, indicating a variation from 0 to 80.5%. The seeds of each sample were sown in 500 mL plastic pots containing autoclaved sand and the seedlings produced were evaluated in relation to the following aspects; emergency, height, lesions in different segments, mortality, abnormalities and transmissibility of symptoms. The study demonstrated that there is a correlation between incidence of PoT in wheat seeds and the following variables related to the seedlings produced; height at 7 days after sowing (DAS), incidence and severity of symptoms at 7, 14 and 21 DAS, and mortality at 14 and 21 DAS. The results confirmed that the establishment and sanity of wheat seedlings directly depend on incidence of PoT in the seeds.

Sabe-se que Pyricularia oryzae Triticum (PoT) sobrevive nas sementes de trigo e esta condição favorece sua disseminação. Há, porém, muitas lacunas no conhecimento relativo aos danos causados por este patógeno em relação ao estabelecimento e à sanidade das plântulas de trigo. O objetivo do trabalho foi verificar se existe correlação entre incidência de PoT em sementes de trigo e variáveis associadas ao estabelecimento e à sanidade das plântulas geradas. Foram utilizadas sete amostras de sementes de trigo naturalmente infectadas com o patógeno. A incidência de PoT em cada uma das amostras de sementes foi determinada via Blotter test indicando variação de 0 a 80,5%. As sementes de cada amostra foram semeadas em copos plásticos de 500 mL contendo areia autoclavada e as plântulas produzidas foram avaliadas em relação aos seguintes aspectos; emergência, altura, lesões em diferentes segmentos, mortalidade, anormalidades e transmissibilidade de sintomas. O estudo demonstrou que existe correlação entre a incidência de PoT em sementes de trigo e as seguintes variáveis relativas às plântulas produzidas; altura aos 7 dias após a semeadura (DAS), incidência e severidade de sintomas aos 7, 14 e 21 DAS, e mortalidade aos 14 e 21 DAS. Os resultados confirmaram que o estabelecimento e a sanidade das plântulas de trigo dependem diretamente da incidência de PoT nas sementes.

Abstract Feeding ecology studies are crucial for understanding energy flow in reef ecosystems. In this study, we used an integrative approach to investigate the diel-feeding ecology of the sergeant-major Abudefduf saxatilis. To examine the possibility of diel-periodicity and size-class differences in foraging behaviour, we tracked fish individuals until their first bite on two subtropical reefs. During each observation, we recorded the substratum that was bitten and estimated the individual’s total length. To assess the diet, we analysed the stomach contents of five individuals from each location. In total, we observed 2,703 individuals biting seven substrates. Our results showed no significant differences in substrate use for diel-periodicity. However, we found significant differences between two size classes. Despite this, both populations tended to forage near the surface in the water column in the morning and on the benthos in the afternoon, although this tendency was not statistically significant. Smaller individuals fed mostly in the water column, while larger individuals foraged on all substrates, likely due to their different energetic demands. Our findings indicate this species has an omnivorous, generalist diet, comprising 12 items from both benthos and plankton. The lack of differences in diel-periodicity is likely due to the sergeant-major’s opportunistic behaviour. ecosystems study dielfeeding diel feeding sergeantmajor sergeant major saxatilis dielperiodicity periodicity sizeclass class behaviour reefs observation individual s length diet location 2703 2 703 2,70 substrates dielperiodicity. periodicity.

Resumo Estudos de ecologia alimentar são cruciais para entender o fluxo de energia em ecossistemas recifais. Neste estudo, usamos uma abordagem integrativa para investigar a ecologia alimentar do sargentinho Abudefduf saxatilis. Para responder se há periodicidade ou diferenças relacionadas a classes de tamanho no substrato forrageado, acompanhamos indivíduos deste peixe até a primeira mordida, em dois recifes subtropicais. Durante cada observação, registramos o substrato mordido e estimamos o comprimento total do indivíduo. Para estudar a sua dieta, analisamos o conteúdo estomacal de cinco indivíduos em cada recife. No total, observamos 2.703 indivíduos mordendo em sete substratos diferentes. Nossos resultados não mostraram diferenças significativas no uso de substrato para a periodicidade diária. No entanto, encontramos diferenças significativas entre duas classes de tamanho. Apesar disso, ambas as populações tenderam a forragear próximo à superfície na coluna d’água pela manhã e no substrato bentônico à tarde, embora essa tendência não tenha sido estatisticamente significativa. Indivíduos menores forragearam principalmente na coluna d’água, enquanto os indivíduos maiores forragearam em todos os tipos de substratos, provavelmente devido às suas diferentes demandas energéticas. Nossos resultados corroboram que o sargentinho tem uma dieta onívora e generalista, composta por 12 itens de ambos os compartimentos, bentônico e planctônico. A falta de diferenças na periodicidade diária é provavelmente devido ao comportamento oportunista do sargentinho. recifais estudo saxatilis forrageado mordida subtropicais observação indivíduo recife 2703 2 703 2.70 entanto disso dágua d água tarde significativa dágua, água, energéticas generalista 1 compartimentos planctônico 270 70 2.7 27 7 2.

RESUMO: Neste estudo Pyricularia spp., P. oryzae e o patótipo Triticum (PoT) de P. oryzae foram detectados e identificados em segmentos foliares de forrageiras e gramíneas invasoras de lavouras de trigo. Em 2018 e 2019, foram coletadas 66 amostras de segmentos foliares lesionados de Urochloa e outras gramíneas em Londrina (PR), Patos de Minas (MG) e Uberaba (MG). A detecção e/ou identificação dos patógenos nas amostras foi realizada por meio de procedimentos de câmara úmida e com os iniciadores MoT3 e Pot2 por PCR. Houve amplificações de DNA com o primer MoT3 (específico para PoT) em 13 (19,69%) das amostras, todas provenientes da Urochloa. O resultado de que Urochloa hospeda PoT em uma taxa relativamente alta levanta preocupações sobre a importância que essas plantas podem ter no ciclo de brusone do trigo como hospedeiro intermediário para o patógeno e / ou fonte de inóculo para a doença.

ABSTRACT: In this study Pyricularia spp., P. oryzae and the P. oryzae pathotype Triticum (PoT) were detected and identified in leaf segments of forage and invasive grasses located in or next to wheat fields. In 2018 and 2019, 66 samples of lesion leaf segments of Urochloa and other grasses were collected in Londrina (PR), Patos de Minas (MG), and Uberaba (MG). The detection and/or identification of the pathogens on the samples was conducted using moist chamber procedures and with the primers MoT3 and Pot2 by PCR. There were DNA amplification with the primer MoT3 (specific for PoT) for 13 (19.69%) of the samples, all of them from Urochloa. The finding that Urochloa hosts PoT at a relatively high rate raises concerns about the importance which these plants may have on the wheat blast cycle as an alternative host for the pathogen and/or source of inoculum for the disease.

Abstract Purpose This study aims to analyze the challenges startups face in implementing business models for sustainability. In particular, the research question of this study is: How do the challenges faced by startups affect business models for sustainability in the context of an emerging country? Design/methodology/approach Startups are increasingly incorporating ways to thrive in a competitive environment with innovative sustainable business models, a key factor for competitive advantage and corporate sustainability. This paper analyses startups’ challenges in adopting business models for sustainability through a case study in two startups, using the sustainable value exchange matrix (SVEM) tool through workshops, to carry out the diagnosis of these challenges. Findings The barriers and challenges of business models for sustainability in startups were found in different categories, where the main barriers are linked to the institutional category, the organizational and the market and sales culture. Thus, the authors concluded that there is a need to reformulate public policies and to have greater participation of the actors involved. Research limitations/implications The main limitation of the research is the number of case studies (only two), which makes it difficult to generalize the results. Practical implications The research presents two major contributions. First, through the case studies, it is possible to verify that the barriers and challenges in business models for sustainability have relevance for startups. The second contribution is the adaptation of SVEM in conducting the debate by incorporating the barriers and challenges in value creation and delivery system. Social implications This study contributes to the business models for sustainability literature to better understand the challenges startups face in practice and can serve as insights to help overcome them. As this is an empirical study, the information gathered can help create metrics and public policies to achieve the United Nations sustainable development goals. Originality/value The present research has as originality the analysis of the challenges in startups in implementing business models for sustainability and their relationships with the value proposition, capture and creation, as well as and delivery (adapted to the challenges found in the literature) applying the SVEM tool proposed by Morioka et al. (2018).

Background: Papillary thyroid carcinomas (PTC) are the most prevalent and least aggressive thyroid carcinomas. In some cases, the diagnosis is doubtfull and the prognosis is poor. The search for tissue biomarkers that make it possible to ensure both the diagnosis for indeterminate cases and the prognosis, identifying the most aggressive cases, has been studied in recent decades. Objective: To analyze the molecular marker cyclin D1 in PTC and multinodular goiter (BMN) and to verify the correlation of the marking with the clinical-pathological characteristics in carcinomas. Methods: 118 tissues from adult patients submitted to PTC thyroidectomy and 40 BMN were selected as a control group. Tissue immunostaining was performed with cyclin D1 with subsequent immunohistochemical analysis in both groups, evaluating the expression of the marker (intensity and distribution). In the PTC group, immunostaining data were also crossed with clinical and pathological data. Results: The majority (93.3%) expressed the staining of cyclin D1 with varying intensities (weak, moderate 3 and strong) and predominantly diffuse distribution (71.2%). The BMN control group expressed staining for cyclin D1 in 57.5%, with weak intensity (47.5%) and sparse distribution (37.5%). The difference between the groups (study and control) was statistically significant (p<0.001). In the CPT group, the clinical-pathological crossings did not show differences regarding age, sex, tumor type and size, lymph node status, focus, angiolymphatic invasion. Conclusion: Cyclin D1 was expressed in the vast majority of PTC with the predominant diffuse distribution. There was no correlation between the expression of cyclin D1 and any clinical-pathological characteristic of PTC.

Racional - Os carcinomas papilíferos são os mais prevalentes e menos agressivos de tireoide (CPT). Em alguns casos, o diagnóstico é duvidoso e o prognóstico ruim. A busca de biomarcadores teciduais que permitam assegurar tanto o diagnóstico para casos indeterminados, quanto o prognóstico, identificando os casos de maior agressividade, têm sido estudadas nas últimas décadas. Objetivo: Analisar a ciclina D1 nos CPT e nos bócios multinodulares (BMN) e verificar a correlação da marcação com as características clinicopatológicas. Métodos: Foram selecionados 118 tecidos de pacientes adultos submetidos àa tireoidectomia por CPT e 40 BMN como grupo controle. Realizou-se imunocoloração tecidual com ciclina D1 com subsequente análise imunoistoquímica em ambos grupos, avaliando-se a expressão do marcador (intensidade e distribuição). No grupo dos CPT os dados da imunocoloração foram também cruzados com os dados clinicopatológicos. Resultados: A maioria (93,3%) expressou a coloração da ciclina D1 com intensidades variadas (fraca, moderada e forte) e distribuição predominantemente difusa (71,2%). O grupo controle dos BMN, expressou coloração para ciclina D1 em 57,5%, com intensidade fraca (47,5%) e distribuição esparsa (37,5%). A diferença entre os grupos (estudo e controle) foi estatisticamente significante (p<0,001). No grupo dos CPT, os cruzamentos clinicopatológicos não evidenciaram diferenças quanto à idade, sexo, tipo e tamanho tumoral, estado linfonodal, focalidade e invasão angiolinfática. Conclusão: A ciclina D1 foi expressa na grande maioria dos CPT sendo a distribuição difusa predominante. Não houve correlação entre a expressão delacom qualquer característica clinicopatológica dos CPT.

Resumo Objetivo Avaliar primariamente a dor pós-operatória, por meio da escala visual analógica (EVA), nos pacientes submetidos a reconstrução do ligamento cruzado anterior (RLCA) que receberam soluções anestésicas intra-articulares (IAs). Métodos Ensaio clínico randomizado com uma amostra de 48 pacientes, divididos em 4 grupos: Grupo I (n ¼ 12) - 20 ml de solução fisiológica (controle); Grupo II (n ¼ 12) - 20 ml de bupivacaína a 0,5%; Grupo III (n ¼ 12) - 20 ml de bupivacaína a 0,5% þ 0,1 mg de epinefrina; e Grupo IV (n ¼ 12) - 20 ml de solução fisiológica þ 0,1 mg de epinefrina, injetados no joelho ao término da cirurgia. A dor foi avaliada pela EVA imediatamente e 6, 12, 24 e 48 horas após o procedimento. Resultados Observou-se grande variabilidade nos resultados da EVA entre os pacientes avaliados em cada grupo. Verificou-se, pela análise de variância (analysis of variance, ANOVA) de Kruskal-Wallis, considerando um nível de 5% de significância, que as soluções anestésicas IAs de cada grupo influenciaram na avaliação da dor desses pacientes (p ¼ 0,003), sendo os do Grupo III os que apresentaram menor dor pósoperatória. Não se evidenciou um maior ou menor consumo de drogas analgésicas suplementares, ou efeitos adversos das decorrentes das soluções empregadas. Conclusão A solução combinada de bupivacaína e epinefrina foi a mais eficaz no controle da dor nos pacientes submetidos a RLCA, mas sem diferenças estatisticamente significativas com relação ao grupo II (p ¼ 0,547). Não se observou diminuição ou aumento no consumo de analgésicos suplementares, ou o aparecimento de efeitos sistêmicos adversos (p > 0,05).

Abstract Objective To evaluate postoperative pain, using the visual analog scale (VAS), in patients undergoing anterior cruciate ligament reconstruction (ACLR) and receiving intra-articular anesthetic solutions. Methods The present is a randomized clinical trial with a sample of 48 patients divided into 4 groups: Group I (n ¼ 12) - 20 mL of saline solution (control); Group II (n ¼ 12) - 20 mL of 0.5% bupivacaine; Group III (n ¼ 12) - 20 mL of 0.5% bupivacaine þ 0.1 mg of epinephrine; and Group IV (n ¼ 12) - 20 mL of saline solution þ 0.1 mg of epinephrine. These solutions were injected into the knee at the end of the surgery. Pain was assessed using the VAS immediately and 6, 12, 24 and 48 hours after the procedure. Results The VAS scores were highly variable among the groups. A Kruskal-Wallis analysis of variance (ANOVA), considering a level of significance of 5%, revealed that all intra-articular anesthetic solutions influenced the assessment of pain (p ¼ 0.003), and that Group-III subjects presented less postoperative pain. There was no evidence of a higher or lower use of supplemental analgesic agents, or of adverse effects resulting from these anesthetic solutions. Conclusion Bupivacaine combined with epinephrine was the most effective solution for pain control in patients undergoing ACLR, but with no statistically significant differences when compared to Group II (p ¼ 0.547). There was no decrease or increase in the use of supplemental analgesics or in the occurrence of adverse systemic effects (p > 0.05).

RESUMO: O primeiro relato da brusone do trigo no mundo foi no Brasil, em 1986. Desde então, tem-se realizado um esforço muito grande com vistas ao desenvolvimento de cultivares de trigo resistentes a esta doença, a qual é causada pelo fungo Pyricularia oryzae Triticum (PoT). O objetivo deste trabalho foi de (i) avaliar a resistência de genótipos de trigo à brusone e (ii) verificar a correlação entre severidade da doença em espigas e taxa de esporulação de PoT em ráquis de espigas. Plantas de 40 cultivares brasileiras de trigo crescidas em vasos, no estádio de florescimento (estádio 65 da escala de Zadoks), foram submetidas à inoculação com uma suspensão de conídios de um isolado de PoT representativo da principal variante do fungo encontrada no Brasil. A severidade de brusone nas espigas aos cinco e sete dias após a inoculação (dai) e a taxa de esporulação do fungo nas ráquis (conídios por g de ráquis) foram avaliadas. Oitenta por cento das cultivares que foram classificadas no grupo com menor taxa de esporulação também foram classificadas no grupo de maior resistência aos sete dai. Entretanto, os coeficientes de correlação da análise estabelecida entre as médias de severidade das cultivares aos cinco e sete dai e as médias da taxa de esporulação de PoT não foram significativos (r=0,2464 e r=0,2047, respectivamente). Os resultados obtidos representam a caracterização atualizada da reação à brusone de cultivares de trigo do Brasil e constituem-se em importante marco exploratório da avaliação da reação de genótipos de trigo baseado na taxa de esporulação de PoT em seus tecidos.

ABSTRACT: The first report of wheat blast in the world was in Brazil, in 1986. Since then, a great effort has been made towards the development of wheat cultivars resistant to this disease, which is caused by the fungus Pyricularia oryzae Triticum (PoT). The objective of this research was to (i) evaluate the resistance of wheat genotypes to blast and (ii) verify the correlation between disease severity on wheat spikes and sporulation rate of PoT on spike rachises. Plants of 40 cultivars grown in pots, at the flowering stage (stage 65 on the Zadoks scale), were inoculated with a suspension of conidia of a PoT isolate representative of the main variant of the fungus reported in Brazil. Severity of blast on the spikes at 5 and 7 days after inoculation (dai) and the rate of sporulation of the fungus on the rachis (conidia per g of rachis) were evaluated. Eighty percent of the cultivars that were classified in the group with the lowest sporulation rate were also classified in the group with the highest resistance at 7 dai. However, the correlation coefficients of the analysis established between the cultivar severity at 5 and 7 dai averages and the PoT sporulation rate averages were not significant (r=0.2464 and r=0.2047, respectively). Results obtained represent the updated characterization to blast of wheat cultivars in Brazil and constitute an important exploratory framework for the evaluation of the reaction of wheat genotypes based on the sporulation rate of PoT on their tissues.

Abstract Microbialites are the most abundant life evidence in Precambrian sedimentary rocks. They are produced by microbial interaction activity and sedimentary processes reflecting paleoenvironmental conditions. The Ediacaran-Cambrian carbonate and siliciclastic successions in the Southern Amazon Craton in Central Brazil, provide a key opportunity to understand how the metazoan life coexisted with the microbial communities. The spatial and temporal distribution of microbialites as well as morphological and paleoenvironmental changes have been assessed, reinterpreting previous works and including new data from the Araras-Alto Paraguai and Corumbá basins. The deposition was controlled by subsidence and sea-level changes that affected these basins, considered extensions of epicontinental seas during the Gondwana assembly. The stromatolites are restricted to coastal deposits and experienced thriving flourishment intervals after the Marinoan Glaciation (635 Ma). Post-glacial transgression was marked by microbial colonization in shallow platforms represented by stratiform and giant domical stromatolites in the Araras-Alto Paraguai Basin. The continuity of the transgression generated a moderately deep aragonite sea at about 622 Ma. A progressive sea-level fall caused the implantation of coastal environments under greenhouse conditions with tidal flat and sabkha settings colonized by centimetric-scale stromatolites. The sea retreat was accompanied by progressive uplift, causing a moderate inversion of the basin and erosion of the succession until ~560 Ma with the deposition of the last preserved tidal flat deposits with the occurrence of thrombolites. The subsiding Corumbá Basin was the site of microbially-induced deposition of carbonates in a shallow platform connected to an offshore setting with the proliferation of metazoan straddling the Ediacaran-Cambrian boundary. Microbial communities were restricted to lagoon deposits during the Lower Cambrian transgression in the Araras-Alto Paraguai Basin and the last phase refers to the sea retreat towards southeast, developing a fluvial system connected with the arid and evaporitic tidal flats colonized by microbialites that lasted until the upper Cambrian. Except for the post-glacial stromatolites, the columnar and domal microbialite indicate that the coastal settings dominated the Ediacaran-Cambrian transition. The preservation of microbialites in the post-glacial intervals can be associated with the Mg-Ca-CO3 oversaturation in dolomitic platforms. The rapid calcification and ability to resist the dissolution and replacement have increased the stromatolites’ preservation potential reported here, where its well-preserved occurrence in tidal flats and sabkha occurs due to intense early diagenetic silicification. The change from carbonate accumulation to siliciclastic-rich environments contributed to the demise of microbially-induced strata. In general, the scarce coexistence between coastal stromatolite and metazoan-bearing marine deposits makes it challenging to establish a competitive relationship between these organisms, as previously postulated.

Abstract Although communication capabilities are displayed by many vertebrate groups, some repertoires are poorly known, such as the case of xenarthrans, particularly armadillos, for which vocalization as a source of communicating to others remains poorly understood and relies on punctual reports of sounds. Here we provide the first description of a behavioral response associated with sound emission of two subjects of Dasypus novemcinctus. Both audio and visual registration was performed to subsequent analyses of expressed behaviors and emitted calls, which accounted for 76 vocalizations from a total of eight video recordings randomly collected from 2017 to 2019. Sound is acoustically characterized by both inhale and exhale phases composed of two vocal units, and no harmonic structure was observed. Once the subjects have always produced these vocalizations while cornered and exhibiting defensive behavior against another subject/human disturbance, these vocalizations were termed as distress. Subjects produced a hiss-purr-like sound while trying to avoid contact with another by bowing or lowering their bodies, humping, or even moving elsewhere when sound production ceased. This shows that the sound repertoire of armadillos is still to be unveiled and seems to be much more complex than previously thought.

Abstract: Improving the process of monitoring pest insects in agricultural areas is a challenge for scientists. The cicada is an insect-pest of the coffee crop that has a distinctive feature of sound emission. A device capable of assisting the farmer in the management of these insects can be of great help in the management of these insects. This work seeks to improve the process of automated monitoring of cicadas in coffee fields by analyzing the range of the device capable of detecting the presence of cicadas in the field. The results showed promising results, encouraging researchers to continue their studies.
