ABSTRACT Selenium (Se) is an antioxidant mineral and has been included in fish feed formulations in the organic form of hydroxy-selenomethionine (OH-SeMet). This study evaluated how different concentrations of this substance, supplemented in the diet, act on tambaqui (Colossoma macropomum) muscle before and after a stressor (transportation). Juvenile fishes were divided into five treatments receiving 0.0; 0.3; 0.6; 0.9; 1.2 mg kg-1 Se supplementation for 75 days. After that period, the fish were exposed to transportation for four hours. Sampling of muscle tissue for the measurement of biochemical parameters occurred on day 75, prior to transportation, and one week after transportation (day 83). The activity of enzymes superoxide dismutase and glutathione-S-transferase did not change. Supplementation with 1.2 mg kg-1 Se increased the level of reduced glutathione before transportation, and 0.9 and 1.2 mg kg-1 Se reduced the level of thiobarbituric acid reactive substances levels before and after transportation. After transportation, we observed reduced glutathione levels in fish treated with 0.3, 0.6 and 1.2 mg kg-1, reduced ascorbic acid level in fish fed 0.6 mg kg-1 Se, and reduced total protein concentration in fish fed 0.3 mg kg-1 Se, as compared to the levels before transportation. In conclusion, the presence of different concentrations of Se in the fish diet promoted different patterns of response to redox status, minimizing oxidative damage generated by the stressor event.

RESUMO O selênio (Se) é um mineral antioxidante e tem sido incluído em formulações de rações para peixes na forma orgânica de hidróxi-selenometionina (OH-SeMet). Este estudo avaliou como diferentes concentrações dessa substância, suplementada na dieta, atuam no músculo do tambaqui (Colossoma macropomum) antes e após um estressor (transporte). Os peixes juvenis foram divididos em cinco tratamentos recebendo a suplementação de 0,0; 0,3; 0,6; 0,9; 1,2 mg kg-1 de Se por 75 dias. Após esse período, os peixes ficaram expostos ao transporte por quatro horas. A amostragem de tecido muscular para medição dos parâmetros bioquímicos ocorreu no dia 75, antes do transporte, e uma semana após o transporte (dia 83). A atividade das enzimas superóxido dismutase e glutationa-S-transferase não se alterou. A suplementação com 1,2 mg kg-1 de Se aumentou o nível de glutationa reduzida antes do transporte, e 0,9 e 1,2 mg kg-1 de Se reduziram os níveis de substâncias reativas ao ácido tiobarbitúrico antes e após o transporte. Após o transporte, observamos redução nos níveis de glutationa reduzida nos peixes tratados com 0,3, 0,6 e 1,2 mg kg-1, redução nos níveis de ácido ascórbico nos peixes alimentados com 0,6 mg kg-1 de Se e redução na concentração de proteínas totais nos peixes alimentados com 0,3 mg kg-1 Se, em comparação com os níveis antes do transporte. Conclui-se que a presença de diferentes concentrações de Se na dieta dos peixes promoveu diferentes padrões de resposta ao estado redox, minimizando os danos oxidativos gerados pelo evento estressor.

Abstract Objective: To investigate the usefulness, reliability, quality, and content of Portuguese-language YouTube videos on COVID-19. Material and Methods: Three keywords selected on Google Trends were searched on YouTube, and the 60 first videos listed with each term were analyzed. Two calibrated researchers evaluated the reliability (DISCERN Modified Scale), the quality (Global Quality Score - GQS), and the usefulness of videos for the users (COVID-19 Specific Score - CSS). The number of views, likes, and engagement were also analyzed. The data were evaluated by the Mann-Whitney test and Spearman correlation (α=5%). Results: 59 videos were included. The average scores of quality, reliability, and usefulness were 3.0 (±1.1), 3.2 (± 0.8), and 1.5 (± 0.9), respectively. Two-thirds of the videos (64.4%) had low/moderate quality, and the majority (76.2%) were about signs and symptoms. The numbers of views (p=0.005), likes (p=0.006), and engagement (p=0.014) were significantly higher in moderate/good quality videos. The number of comments (p=0.007), duration of videos (p=0.004), and the DISCERN score (p<0.001) were significantly higher in videos made by health professionals. The general quality of the videos was positively correlated to the CSS scores, number of views, likes, and engagement (p<0.05). Conclusion: Most videos had moderate quality and reliability and low usefulness for the users.

Abstract The mining industry in Peru - as well as in many resource-rich countries of the global South - is of great economic and social importance, particularly in remote regions where mineral deposits are often located. The academic literature has so far neglected analysing how women in these regions are affected by the industry. As such, it is relevant to study the gendered conflict surrounding the activity and invisibility of women in the mining industry, as well as their proposals, demands, and needs, with a focus on environmental and social concerns. This study analysed the experiences of peasant women from Peruvian Andes communities in environmental governance processes in mining contexts as they sought to exercise their citizenship within the mining industry and public spaces. Using a qualitative approach involving a focus group and panel discussions, the experiences and perceptions of the women who are part of the participatory environmental monitoring and surveillance committees (PEMSC) were considered. This paper highlights gendered inequalities concerning the benefits of mining, the process of change in the social dynamics of mining communities, and political claims for a better social arrangement, with social, political, economic, and ecological considerations from the women’s point of view.

Resumo A indústria de mineração no Peru - assim como em muitos países ricos em recursos do Sul global - é de grande importância econômica e social, particularmente em regiões remotas onde frequentemente estão localizados depósitos minerais. Até agora, a literatura acadêmica negligenciou a análise de como as mulheres nessas regiões são afetadas pela indústria. Assim, é relevante estudar o conflito de gênero em torno da atividade e invisibilidade das mulheres na mineração, bem como suas propostas, demandas e necessidades, com foco nas preocupações ambientais e sociais. Este estudo analisou as experiências de mulheres camponesas de comunidades andinas peruanas em processos de governança ambiental em contextos de mineração enquanto buscavam exercer sua cidadania dentro da indústria de mineração e espaços públicos. A partir de uma abordagem qualitativa envolvendo um grupo focal e painéis de discussão, foram consideradas as experiências e percepções das mulheres que integram os comitês participativos de monitoramento e vigilância ambiental (PEMSC). Este artigo destaca as desigualdades de gênero em relação aos benefícios da mineração, o processo de mudança na dinâmica social das comunidades mineradoras e as reivindicações políticas por um melhor arranjo social, com considerações sociais, políticas, econômicas e ecológicas do ponto de vista das mulheres.

Vegetable oils are alternatives to producing renewable monomers since they are biomass. It is possible to react them with anhydrides by heating to provide monomers with high reactivity. However, after the reaction of grape seed oil with itaconic anhydride, it was observed the occurrence of parallel reactions that had not been observed when the same oil was reacted with maleic anhydride. Some articles in the literature have reported that temperature and bases can isomerize itaconic anhydride into citraconic anhydride, which is more stable at room temperature. However, they have not focused on completely understanding how this phenomenon occurred nor studied it in processes that involve microwave irradiation. Therefore, this paper presents a complete characterization and investigation about the thermal behavior of itaconic anhydride and how it can affect the monomer synthesis performed under heating. biomass reactivity However irradiation Therefore

Abstract Guarana (Paullinia cupana) is a native plant from the Amazon whose seeds contain a high concentration of caffeine. Aqueous extract of guarana is widely used in the world. In this study, the objective was to develop and validate a High-Performance Liquid Chromatography method for the determination of caffeine in extracts and commercial beverages based on guarana. A sensitive, simple, and viable high performance liquid chromatographic method without the need of an analyte extraction procedure was developed and validated according to Brazilian and international requirements. The method presented high performance, fulfilling Brazilian and international requirements, in addition to allowing product compliance tests. Results confirmed high selectivity and linearity (>0.999) between 5 to 135 ug/mL, with no significant matrix effect. Detection and quantification limits were 0.02 µg/mL and 2 µg/mL, respectively. Precision was less than 4 %, and accuracy varied from 99.9-120 %. Applicability of the method was demonstrated by conducting a limited evaluation in products containing caffeine. Commercial extracts showed quite different caffeine levels, while carbonated drinks follow Brazilian and American recommendations. Our results indicate that the developed method can be used to evaluate the quality of the guarana extract and of products containing caffeine.

ABSTRACT This study uses Foucault’s theory of subjectivity for a deeper understanding of how anti-fans react to the insertion of political identities in the narratives of media products. The research considers the growing insertion of representativeness in the entertainment industry and the fact that fan communities are conducive to disagreements and resistance. The study assessed how Star Wars anti-fans reacted to the introduction of characters representative of political identities in the new phase of the saga. Foucault’s archeogenealogical method was used to analyze messages posted on the franchise’s biggest fan forum from 2014 to 2020. Results pointed to two moral agencies descriptive of intolerance and amorality, which converge to a subject-form searching for “normality.” These findings have indicated a segregation behavior, which perpetuates a given social status quo and mobilizes desires to impose it, a fact that features what Foucault defined as fascist life.

RESUMEN Este estudo utiliza a teoria da subjetividade de Foucault para compreender melhor como os antifãs reagem à inserção de identidades políticas nas narrativas dos produtos midiáticos, levando em consideração a crescente inserção da representatividade na indústria do entretenimento e o fato de que as comunidades de fãs são um ambiente propício para desentendimentos e resistências. Para tanto, avaliamos como os antifãs de Star Wars reagiram à introdução de personagens representativos de identidades políticas na nova fase da saga. O método arqueogenealógico de Foucault foi utilizado para analisar as mensagens postadas no maior fórum de fãs da franquia entre 2014 e 2020. Os resultados apontaram para duas agências-morais descritivas da intolerância e da amoralidade, que convergem para uma forma-sujeito que busca uma “normalidade”. Esses achados indicaram um comportamento segregacionista, que perpetua um determinado status quo social e mobiliza desejos de impô-lo, fato que caracteriza o que Foucault definiu como vida fascista.

ABSTRACT Introduction: many revascularization techniques were designed to reduce the imbalance of ischemia-reperfusion injury. This study’s objective is to evaluate retrograde reperfusion (RR) compared to sequential anterograde reperfusion (AR), with and without the washout technique (WO). Method: this prospective cohort study collected data from 94 deceased donor orthotopic liver transplants and divided it into three groups: RR with WO (RR+WO), AP with WO (AR+WO), and AP without WO (AR). This study did not assign the reperfusion technique to the participants. The primary outcome considered the early graft dysfunction, and secondary outcomes included post-reperfusion syndrome (PRS), post-reperfusion lactate, surgery fluid balance, and vasoactive drug dose during the surgery. Results: 87 patients were submitted to the final analysis-29 in the RR+WO group, 27 in the AR+WO group, and 31 in the AR group. Marginal grafts prevalence was not significantly different between the groups (34% vs. 22% vs. 23%; p=0.49) and early graft dysfunction occurred at the same rate (24% vs. 26% vs. 19%; p=0.72). RR+WO reduced serum post-reperfusion lactate (p=0.034) and the incidence of significant PRS (17% vs. 33% vs. 55%; p=0.051), but norepinephrine dosing >0.5mcg/kg/min were not different during the surgery (20,7% vs. 29,6% vs. 35,5%, p=0.45). Conclusions: primary outcome was not significantly different between the groups; however, intraoperative hemodynamic management was safer using the RR+WO technique. We theorized that the RR+WO technique could reduce the incidence of PRS and benefit marginal graft survival following diseased donor orthotopic liver transplantation.

RESUMO Introdução: várias técnicas de reperfusão foram desenvolvidas a fim de reduzir o dano da lesão induzida por isquemia-reperfusão. Este estudo objetivou avaliar a reperfusão retrograda (RR) comparado com a reperfusão anterógrada (AR), com e sem a realização da técnica de lavagem do enxerto (WO). Métodos: coorte prospectiva com 94 transplantes ortotópicos de fígado de doador falecido divididos em três grupos: RR com WO (RR+WO), reperfusão anterógrada com WO (AR+WO), e AR sem WO (AR). Este estudo não designou a técnica de reperfusão entre os participantes. O desfecho primário considerou a disfunção precoce do enxerto, e os desfechos secundários incluíram a síndrome pós-reperfusão (SPR), lactato pós-reperfusão, balanço hídrico operatório, e uso de drogas vasoativas durante o ato peratório. Resultados: 87 pacientes foram submetidos para consolidação dos dados-29 no RR+WO, 27 no AR+WO, e 31 no AR. A prevalência de enxertos maginais não diferiu entre os grupos (34% vs 22% vs 23%; p=0,49). Disfunção precoce do enxerto ocorreu em uma proporção similar (24% vs 26% vs 19%; p=0,72). RR+WO reduziu o lactato sérico pós-reperfusão (p=0,034) e a incidência de SPR severa (17% vs 33% vs 55%; p=0,051), entretanto a infusão de noradrenalina >0,5mcg/kg/min não foi diferente durante a cirurgia (20,7% vs 29,6% vs 35,5%, p=0,45). Conclusões: o desfecho primário não diferiu significativamente entre os grupos; entretanto, o manejo hemodinâmico intra-operatório foi mais seguro no grupo RR+WO. Nós teorizamos que a técnica RR+WO pode reduzir a SPR e beneficiar enxertos marginais no transplante de fígado.

ABSTRACT Objective: The aim of this study was to compare the stress distribution in internal tapered connection implants with different adaptation geometries submitted to oblique load simulation using the Finite Element Analysis (FEA) method. Methods: Three different internal tapered implant-abutment assemblies were modeled by varying only the diameter of the abutment body in the cone region. The dimensions of the implants were 4.0 mm in diameter and 13 mm in length. Oblique loads of 210 N angled 30 degrees to the long axis of the implant were applied to a hemispherical body positioned over the abutments simulating a dental crown. The stress generated by the implant-abutment assembly was analyzed by the FEA method using the von Mises criterion. Results: A higher concentration of stress in the coronal region (collar) and implant body on the opposite side of the load application was shown, as well as in the body region of the abutments and in the screw threads. The cervical region of the implants showed the highest von Mises stress values, the highest values being observed in G3 (1034 MPa), followed by G2 (841 MPa) and G1 (702 MPa). Conclusion: According to the results presented, it can be concluded that the stress distribution was more homogeneous and less concentrated in the G1 implant-abutment assembly. Therefore, the use of abutments with dimensions standardized by the implant manufacturer is recommended.

RESUMO Objetivo: O objetivo deste estudo foi comparar a distribuição de tensões em implantes de conexão cônica interna com diferentes geometrias de adaptação submetidos à simulação de carga oblíqua pelo método de Análise de Elementos Finitos (FEA). Métodos: Três diferentes conjuntos implante-pilar cônicos internos foram modelados variando apenas o diâmetro do corpo do pilar na região do cone. As dimensões dos implantes foram de 4,0 mm de diâmetro e 13 mm de comprimento. Cargas oblíquas de 210 N anguladas 30 graus em relação ao longo eixo do implante foram aplicadas sobre um corpo hemisférico posicionado sobre os pilares simulando uma coroa dentária. A tensão gerada pelo conjunto implante-pilar foi analisada pelo método FEA utilizando o critério de von Mises. Resultados: Foi evidenciada maior concentração de tensões na região coronal (colar) e corpo do implante no lado oposto da aplicação da carga, assim como na região do corpo dos pilares e nas roscas dos parafusos. A região cervical dos implantes apresentou os maiores valores de tensão de von Mises, sendo os maiores valores observados em G3 (1034 MPa), seguido de G2 (841 MPa) e G1 (702 MPa). Conclusão: De acordo com os resultados apresentados, pode-se concluir que a distribuição de tensões foi mais homogênea e menos concentrada no conjunto implante-pilar do G1. Portanto, recomenda-se o uso de pilares com dimensões padronizadas pelo fabricante do implante.

ABSTRACT Objective To evaluate and characterize the quality of ophthalmic care offered in an outpatient service unit of the SUS secondary care according to the perception of users and/or those responsible for these users. Methods A cross-sectional study of analytical prevalence was carried out among users assisted from September 2019 to March 2020, in one of the six ophthalmic care services offered by the SUS, in the municipality of Vitória da Conquista (BA), Brazil. Demographic and socioeconomic conditions, as well as self-perception of health, were evaluated. The characteristics and quality levels of ophthalmic health care were also evaluated. Data collection took place through a telephone interview. Results A total of 389 users and/or guardians participated in the study. Participants reported high levels of satisfaction, considering the questions that make up the instrument’s construct. Compromised quality levels were observed in relation to the freedom to choose their eye care provider (n=154; 39.7%). Lower levels of satisfaction were associated with the variables male gender (OR=1.66; 95%CI=1.04-2.65; p=0.033) and self-reported white race (OR=6.89; 95%CI=4, 00-11.86; p=0.000). Conclusion Users reported good levels of satisfaction with eye health care. There were greater chances of lower levels of satisfaction among men and among those with a self-reported white race.

ABSTRACT. Brassica spp. production can be negatively affected by clubroot, which is caused by the protozoan Plasmodiophora brassicae Woronin. Most of the information on clubroot control is derived from studies in temperate regions. Here, management strategies were evaluated to reduce broccoli (Brassica oleracea L. var. italica Plenck) crop losses owing to clubroot in tropical mountain regions. The first experiment revealed the effect of green manure from coriander (Coriandrum sativum L.), sunn hemp (Crotalaria juncea L.), sweet corn (Zea mays L.), and spontaneous vegetation (control) associated with broccoli seedlings of 4 different sizes. In the second experiment, the effect of soil amendments (limestone and steel slag) in conjunction with poultry litter (fresh or composted for 45 days) and without poultry litter (control), was assessed. Both field experiments sought to evaluate the disease intensity, plant development (root growth, biomass, and nutrient accumulation), and yield. Sunn hemp and coriander biomass resulted in higher healthy root volumes and dry weights of broccoli. However, such benefits were not derived from corn treatment. Compared to smaller seedlings (10 mL cell and 20 days of age, and 16 mL cell and 24 days of age), the use of larger seedlings (35 mL cell and 28 days of age, and 50 mL cell and 32 days of age) resulted in lower intensity of clubroot and increased the average yield by 143% in summer crops. Steel slag, like limestone, corrected soil acidity and resulted in plant growth; however, clubroot intensity was not significantly affected. Fresh and composted poultry litter increased the percentage of diseased roots compared with the control; however, broccoli yield was not affected by the treatments. Using green manure (sunn hemp or coriander) and well-developed seedlings is recommended as a strategy to reduce losses induced by clubroot during broccoli cultivation.

Abstract Different governmental and non-governmental actors seek to mobilize scientific evidence to support work on public policies. In recent decades, studies have emphasized analytical capacities from the point of view of individuals – mainly public servants and government managers – or organizations – ministerial structures or independent agencies. This article innovates previous investigations in seeking to understand how individual and organizational dimensions interact to expand the mobilization of evidence produced by science. The research used an extensive N survey with bureaucrats from the Brazilian federal public administration. The findings indicate that these two dimensions interact positively for greater use of scientific evidence. However, special attention must be paid to how organizational resources are conceptualized and operationalized. As a specialized unit, the interaction with the ability to identify, collect and analyze data and information related to public policy proved to be important. As a resource or organizational availability, the interaction with the education of individuals proved to be a relevant dimension. Finally, as an organizational relationship opportunity with academia, the interaction with the level of formal education was also significant. Future research should seek to explain why other forms of interaction between individual and organizational capabilities are not relevant, in addition to seeking to understand the causal mechanisms that explain the identified findings.

Résumé Différents acteurs gouvernementaux et non gouvernementaux cherchent à mobiliser des preuves scientifiques pour soutenir les travaux sur les politiques publiques. Au cours des dernières décennies, des études ont mis l’accent sur les capacités d’analyse du point de vue des individus – principalement des fonctionnaires et des gestionnaires de l’État – ou des organisations – structures ministérielles ou agences indépendantes. Cet article innove les enquêtes précédentes en cherchant à comprendre comment les dimensions individuelles et organisationnelles interagissent pour élargir la mobilisation des preuves produites par la science. La recherche a utilisé une vaste enquête N auprès des bureaucrates de l’administration publique fédérale brésilienne. Les résultats indiquent que ces deux dimensions interagissent positivement pour une plus grande utilisation des preuves scientifiques. Cependant, une attention particulière doit être accordée à la façon dont les ressources organisationnelles sont conceptualisées et opérationnalisées. En tant qu’unité spécialisée, l’interaction avec la capacité d’identifier, de collecter et d’analyser des données et des informations liées à la politique publique s’est avérée importante. En tant que ressource ou disponibilité organisationnelle, l’interaction avec l’éducation des individus s’est révélée être une dimension pertinente. Enfin, en tant qu’opportunité de relation organisationnelle avec le milieu universitaire, l’interaction avec le niveau d’éducation formelle était également importante. Les recherches futures devraient chercher à expliquer pourquoi d’autres formes d’interaction entre les capacités individuelles et organisationnelles ne sont pas pertinentes, en plus de chercher à comprendre les mécanismes causaux qui expliquent les résultats identifiés.

Resumo Diferentes atores governamentais e não governamentais buscam mobilizar evidências científicas para subsidiar o trabalho em políticas públicas. Nas últimas décadas, estudos têm enfatizado as capacidades analíticas do ponto de vista de indivíduos - principalmente servidores públicos e gestores públicos - ou organizações - estruturas ministeriais ou órgãos independentes. Este artigo inova investigações anteriores ao buscar compreender como as dimensões individual e organizacional interagem para ampliar a mobilização das evidências produzidas pela ciência. A pesquisa utilizou-se de um survey com extensa amostra de burocratas da administração pública federal brasileira. Os achados indicam que essas duas dimensões interagem positivamente para maior utilização das evidências científicas. No entanto, atenção especial deve ser dada à forma como as capacidades organizacionais são conceituadas e operacionalizadas. Como unidade especializada, a interação com a capacidade de identificar, coletar e analisar dados e informações relacionados à política pública mostrou-se importante. Como recurso ou disponibilidade organizacional, a interação com a educação dos indivíduos revelou-se uma dimensão relevante. Por fim, como oportunidade organizacional de relacionamento com a academia, a interação com o nível de educação formal também se mostrou significativa. Pesquisas futuras devem buscar explicar por que outras formas de interação entre capacidades individuais e organizacionais não são relevantes, além de buscar compreender os mecanismos causais que explicam os achados identificados.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract Continental margins usually have a high degree of environmental heterogeneity, which, in turn, promotes high benthic biodiversity. The South-Southeast regions concentrate the most well-mapped areas of the Brazilian continental margin regarding seafloor geomorphology and physical oceanography. However, the structure of the soft-sediment benthic fauna of the continental slope is still unknown. Characterization and understanding of the Brazilian continental slope biota are imperative since human activities are increasing in the last decades, especially after the discovery of the pre-salt reservoir in Santos Basin. In this study, we aimed to establish a baseline of the spatial distribution of the benthic macrofaunal communities regarding their latitudinal and bathymetric patterns in the Santos Basin to support future environmental monitoring activities in the region. As part of the Santos Project – The Santos Basin Regional Environmental Characterization (PCR-BS) – coordinated by CENPES/PETROBRAS, a benthic oceanographic cruise was carried out in 2019. Sediment samples were collected using a GOMEX-type box corer in 47 stations distributed in eight transects (400– 2,400 m depth range). In total, 12 additional stations (1,300–2,200 m) were defined to cover an area where oil and gas are exploited. Our results showed that macrofaunal assemblages of the Santos Basin present strong depth zonation related to changes in organic matter input, as well as to temperature, carbonate, and grain size. At local scale, the northern sector stood out for having a higher abundance of macrofauna in the upper slope (400 m) and it probably reflects the oceanographic processes and the organic enrichment caused by the upwelling events that occur at Cabo Frio region. The zonation pattern and the dominance of some polychaete, peracarid crustacean, and bivalve families were similar to other SE Brazilian continental margins.

ABSTRACT. This study aimed to produce mechanically separated meat (MSM) from tilapia obtained at the Teresina fish market in the state of Piauí, Brazil. Waste production and disposal and yields were estimated, and physico-chemical and microbiological MSM qualities were determined. A questionnaire was applied to the fish market sellers, followed by tilapia carcass sampling for MSM production and assessments concerning yields, microbiological (Escherichia coli and Staphylococcus coagulase positive counts and the detection of Salmonella spp.) and physicochemical (water activity, pH, reaction to hydrogen sulfide and ammonia) quality and proximate composition (moisture, ash, proteins, lipids, carbohydrates and total energy value). The questionnaire results indicated that tilapia is highly in demand and thats processing leads to significant waste. The yield analysis indicated that tilapia MSM presents adequate residual meat extraction rates from tilapia carcasses. All microbiological analyses were in compliance with Brazilian standards. Physicochemical results were as follows: protein (14.9 to 16.1%), lipids (16.6 to 22.1%), ash (1.3 to 2.8%), moisture (60.6 to 64 .1%), carbohydrates (0.6 to 1.5%) and calories (216.5 to 263.1 kcal 100-1). It is, therefore, clear that MSM constitutes a safe and nutritious foodstudd and comprises a viable alternative for the development of co-products.

ABSTRACT This report examines the effects of calcium anacardate (CA) on the morphology, histology, and proteomics of the testes and epididymal ducts of breeding quail. To that end, 22 140-day-old males were grouped in four treatments, each with different concentrations of CA: 0% (control), 0.25%, 0.50%, and 0.75%. The testicles of the animals were weighed and measured, and proteins from the testicles were separated by 1D SDS-PAGE and analyzed via mass spectrometry. Overall, 35 bands were identified in the testicular tissue gels of European quail. Of these, 13 were significantly different, with treatment 0.75% CA being different from the control in all bands. Significant differences among the mean heights of the seminiferous epithelium and diameters of the epididymal duct were observed. In the control group, the average height of the seminiferous epithelium was 71.2 µm, and in 0.75% CA, it was 45.6 µm. Supplementing feed with CA altered the expression of specific proteins, such as superoxide dismutase and heat shock proteins, of the seminal plasma of quail, in addition to facilitating histological alterations regarding the height of the seminiferous epithelium and the diameter of the epididymal duct, improving the reproductive parameters.
