Performance of castor oil polyurethane resin in composite with the piassava fibers residue from the Amazon.

The use of castor oil in producing polyurethane resins has been identified as one of the most promising options for the industry. The piassava fibers waste generated by the industry on a large scale presents excellent properties as a reinforcing agent due to its high lignin content characterized by chemical tests and FTIR. Composite boards consisting of a higher content of mercerized piassava fibers (10 mm, 85 wt.%) reinforced polyurethane castor oil-based resin (prepolymer (PP) and polyol (OM)) exhibited excellent performance. Composites with these properties have strong potential for medium-density applications ranging from biomedical prosthetics to civil partition walls and insulation linings. Alkali treatment removed the superficial impurities of piassava fibers, activating polar groups, and physical characterization reported excellent performance for all composites. Among the composites, the CP3 sample (composite reinforced with piassava fibers (85 wt.% fibers; 1.2:1-PP:OM)) stood out with higher density and lower swelling and water absorption percentage than other composites. FTIR results indicated NCO traces after the resin cured in the PU3 (1.2:1-PP:OM), possibly contributing to the interaction with the fibers. DMA results reported relevant information about more flexibility to CP1 (composite reinforced with piassava fibers (85 wt.% fibers; 0.8:1-PP:OM)) and CP3 than CP2 (composite reinforced with piassava fibers (85 wt.% fibers; 1:1-PP:OM)). The results suggest that the proper combination with natural products must lead to composites with potential applications as engineering materials.

Laparoscopic resection of large oncocytoma with metaplastic ossification: Case report and video.

Renal oncocytoma (RO) represents about 7% of kidney tumors. They usually behave in a benign fashion, with a slow-growth rate. Patients are often asymptomatic and the tumour is found incidentally on imaging. Due to its wide variation of presentations and multiple radiological findings it is difficult to differentiate RO from renal-cell carcinomas. Interpretation of the images in the appropriate clinical context is crucial and supports the surgeon to avoid aggressive surgical procedures in favor of a nephron-sparing approach, whenever possible. We report a case of a 71-year-old female patient with a large calcified RO which was resected laparoscopically.

Políticas informadas por evidências: cuidado às oclusopatias nas redes de atenção à saúde / Policies informed by evidence: malocclusions treatment in public health

O panorama atual da atenção às oclusopatias no Brasil se caracteriza por elevada incidência e insuficiente capacidade de cobertura. As oclusopatias ocupam ainda o terceiro lugar dentre os agravos bucais mais prevalentes no mundo em que mais da metade da população brasileira nas idades de 5 a 12 anos é acometida. A capacidade de cobertura da rede instalada mostra-se aquém das necessidades da população e a atenção prestada é ofertada principalmente pelo setor privado. Diante do exposto se faz necessário identificar as evidências disponíveis e experiências relevantes ao cuidado das oclusopatias, de modo a guiar a tomada de decisão em políticas públicas de saúde. O objetivo desta pesquisa é analisar e sintetizar as evidências voltadas às oclusopatias a fim de informar a tomada de decisão com consequente planejamento de uma proposta de intervenção na APS para o enfrentamento do problema e das grandes filas vivenciadas no serviço público de Suzano/SP. A metodologia é abordada neste trabalho, de forma segmentada, em três fases: 1 - EVIDÊNCIA PARA TOMADA DE DECISÃO, em que foi realizada uma revisão de escopo para a identificação das evidências disponíveis para uma possível solução ao problema; 2 - PROPOSTA DE INTERVENÇÃO NA APS, em que se estruturou um curso de capacitação via ambiente virtual de aprendizado Moodle para o enfrentamento das oclusopatias na APS e avaliação das percepções da ESB em relação às competências desenvolvidas no curso e contribuição para a prática no serviço; 3 MELHORAMENTO CONTÍNUO, em que se realizou um Diálogo Deliberativo como estratégia de identificar a perspectiva dos stakeholders e aprimoramento necessário para a sustentabilidade da intervenção proposta e implementação como política pública de saúde. De 1.393 artigos identificados na base de dados consideradas na revisão de escopo, foram incluídos no estudo apenas 6 artigos para sua análise e extração dos dados de caracterização, constatando-se que apesar de abrangente as evidências disponíveis na literatura referente às oclusopatias, estudos sobre o enfrentamento ao problema no âmbito do serviço público de saúde é escasso. Após a realização do curso de capacitação, a maioria dos profissionais se sentiu apto para atuação no cuidado às oclusopatias dentro da APS, somado a alta taxa de aceitação da intervenção (97%). O Diálogo Deliberativo identificou a proposta como uma política pública viável ao enfrentamento do problema, em que se evidenciou um grande avanço na atenção prestada às oclusopatias na APS, assim como redução do número de encaminhamentos desnecessários para o CEO. Conclui-se, portanto que se deve explorar ao máximo a potencialidade das RAS e posicionar a APS como o local em que a atenção às oclusopatias deve ser iniciada, de modo a viabilizar sua identificação precoce e cuidado, evitando tratamentos mais complexos e onerosos para o sistema público de saúde e contribuindo para a integralidade no cuidado. O curso de capacitação foi o produto educacional desenvolvido neste trabalho para atuação no cuidado às oclusopatias na Atenção Primária à Saúde.

A giant hybrid organic-inorganic octahedron from a narrow rim carboxylate calixarene.

Here we discovered an unprecedented giant octahedral coordination compound bearing 16 Zn2+, 12 Na+, 8 O2-, 4 OH-, 13 H2O and 6 L4- ligands [L4- = fully deprotonated tetra(carboxymethoxy)calix[4]arene]. Its structure was elucidated by single-crystal X-ray diffraction, wavelength-dispersive X-ray spectroscopy and MALDI-TOF mass spectrometry. This compound, Zn8Na6L6⊃Zn8Na6O8(OH)4(H2O)13 (external⊃internal), has eight tetrahedral zinc ions forming the coordination vertices of an outermost cube where carboxylate groups from the sodium calixarenes are anchored. Its core consists of eight Zn2+, six Na+, eight O2-, and four OH- distributed over three layers, besides thirteen coordinated H2O molecules.

River-floodplain restoration and hydrological effects on GHG emissions: Biogeochemical dynamics in the parafluvial zone.

The parafluvial zone is frequently exposed to drying-rewetting cycles with critical consequences for the biogeochemistry of soil and sediment in river-floodplain landscapes. Upon restoration of the hydrological connectivity, substantial changes in biogeochemical processes are expected. The effects of water fluctuation on the magnitude of GHG emissions were investigated in the parafluvial zone of a restored river floodplain in Austria. Sediment composition, DOM quality and N2O, CO2, CH4 fluxes were quantified during distinct hydrological periods (intermittent, desiccation and post flood) and along a hydrological gradient. The hydrological gradient ranged from non-flooded plots in the floodplain soil (used as reference plots after restoration), to rarely-flooded and frequently flooded sediment plots in the parafluvial zone. Enhanced biogeochemical turnover rates were identified during the intermittent period, when N2O and CO2 emissions peaked. In particular, the frequently flooded plots showed significantly higher CO2 and CH4 emissions compared to non-flooded and rarely-flooded plots. This indicates a strong effect of water level fluctuation on GHG emissions, with higher emissions occurring during transitional stages of drying and rewetting. Strong positive relationships were found between individual GHG fluxes, suggesting a tight link between C and N cycles. Both the C and N cycles are dependent on similar substrate characteristics that are governed by the quality of the DOM pool. Interestingly, drier sediments in the rarely-flooded plots were also active areas for emissions. This highlights the importance to include dry phases and sites in the overall C and N emission estimates of riverine landscapes. From the restoration point of view, N2O emissions in the parafluvial zone did not differ significantly from the emissions in the reference plots, whereas CO2 and CH4 fluxes did. When making management decisions to restore connectivity, one needs to carefully consider the interplay between nutrient removal from water versus GHG emissions, to reach maximum environmental benefits.

Effects of 2 Types of Resistance Training Models on Obese Adolescents' Body Composition, Cardiometabolic Risk, and Physical Fitness.

Magnani Branco, BH, Carvalho, IZ, Garcia de Oliveira, H, Fanhani, AP, Machado dos Santos, MC, Pestillo de Oliveira, L, Macente, SB, and Nelson, NJ. Effects of 2 types of resistance training models on obese adolescents' body composition, cardiometabolic risk, and physical fitness. J Strength Cond Res 34(9): 2672-2682, 2020-The main objective of this study was to investigate the effects of 2 types of resistance training (RT) models in conjunction with interdisciplinary interventions by other health professionals to reduce the body fat and cardiometabolic risk of obese adolescents while improving their general health-related physical fitness. The 12-week analyses involved 18 male adolescents who were split into 2 groups (weight lifting: n = 9 and functional: n = 9), with equalization according to the primary muscle group (whenever possible), the effort:pause ratio, and intensity. The results showed reductions in fat mass and body fat, as well as in waist and hip circumferences (p < 0.05) after the intervention period. However, no significant differences were observed in terms of the body mass, body mass index, neck circumference, systolic and diastolic blood pressures, and for lean mass (p > 0.05) after the respective period. Maximal isometric strength, abdominal strength resistance, flexibility, and maximal oxygen consumption all produced significant increases after the interventions (p < 0.05). There were reductions in low-density lipoproteins and triglyceride levels after the intervention period (p < 0.05). For fasting glycemia, high-density lipoproteins, and alanine aminotransferase, no differences were observed (p > 0.05). In addition, no differences were observed in rating of perceived recovery, internal training load, or caloric intake (p > 0.05). With the results presented, it is concluded that both RT methods were effective at reducing both fat mass and body fat, thus improving health-related physical fitness components and decreasing cardiometabolic risk.

Determining the Polymorphism Information Content of a molecular marker.

This review was carried out with the purpose of contributing to the discussion on the equations used in calculating the Polymorphism Information Content (PIC) of molecular markers. PIC measures the ability of a marker to detect polymorphisms, and therefore has enormous importance in selecting markers for genetic studies. We perform a summary analysis of PIC and its difference in relation to heterozygosity, another parameter used to evaluate the quality of a marker, presenting and discussing the several equations registered in the literature for both dominant and codominant markers. Finally, we present a brief direction on estimating PIC for dominant markers.

The RAPid COmmunity COGnitive screening Programme (RAPCOG): Developing the Portuguese version of the Quick Mild Cognitive Impairment (Qmci-P) screen as part of the EIP on AHA Twinning Scheme.

As populations age and the prevalence of cognitive impairment increases, healthcare professionals and researchers require short, validated cognitive screening instruments (CSIs). As part the EIP-on-AHA Twinning Support Scheme (2016), four reference sites developed the RAPid COmmunity COGnitive screening Programme (RAPCOG) twinning project to validate translated versions of the Quick Mild Cognitive Impairment (Qmci) screen that could be adapted quickly for use with future eHealth screening and assessment programmes. Here we present the cultural adaption and translation of the Qmci-Portuguese (Qmci-P) screen as part of RAPCOG and explore its subsequent validation against two commonly-used CSIs (MMSE-P and MoCA-P) with 93 participants aged ≥65, attending ten day care centres or resident in two long-term care institutions; median age 74 (+/-15), 66% female. The Qmci-P's internal consistency was high (Cronbach's Alpha 0.82), compared with the MoCA (0.79) and SMMSE (0.54). Qmci-P screen scores moderately correlated with the SMMSE (r=0.61, 95% CI:0.45-0.72, p<0.001) and MoCA (r=0.63, 95% CI:0.36-0.80, p<0.001). The Qmci-P screen demonstrates high internal consistency and concurrent validity against more established CSIs and given its brevity (3-5mins), may be preferable for use in community settings. This project shows the potential of the EIP-on-AHA Twinning initiative to promote the scaling-up of innovative good practices.

Feeding frequency affects feed intake and growth in juvenile pirarucu (Arapaima gigas)

Pirarucu is one of the main fish species for the development of aquaculture in the Amazon. In this study, the optimal feeding frequency for juvenile pirarucu was assessed based on growth and feed efficiency. Juvenile pirarucu weighing ca. 80 g were fed once, twice, three or four times daily until apparent satiation for 63 days. Fish fed three or four times per day presented higher growth, feed intake, and fat body content than those fed once or twice per day. There was no significant difference for feed conversion ratio, and protein and energy retention rates among treatments, suggesting that increased feeding frequency did not affect feed utilization efficiency. Mean feed intake per meal was higher when fish were fed once per day, possibly causing hyperphagic behavior. Results suggest that feeding three times per day was sufficient to secure adequate feeding and growth of juvenile pirarucu. (AU)

Simulation of pattern of gene flow in Canjerana fragments in the Brazilian Atlantic Rainforest for evaluating genetic conservation strategies / Simulação do padrão de fluxo gênico em fragmentos de Canjerana no bioma Mata Atlântica para definição de estratégias de conservação genética

ABSTRACT: Gene flow is important for the conservation of genetic resources to allow connectivity of geographically isolated populations and which genetic variability is reduced. Gene movement is a function of flow rate and model. Understanding how gene flow occurs can contribute to the conservation and selection of priority populations that could benefit from an eventual intervention. Simulation softwares allow making inferences about past events based on current datasets or predict future phenomena under real genetic scenarios. Adverse phenomena can be predicted and actions can be taken to avoid them. The aim of this study was to identify a model and the gene flow rates that could explain genetic structure of eight forest fragments of Cabralea canjerana in development in the Brazilian Atlantic Rainforest. To do this, simulations were performed with the EASYPOP software using a microsatellite marker dataset obtained for the species by Melo and collaborators, in 2012, 2014 and 2016. We tested five models and nine migration rates and we selected the model that produced values closer to those previously obtained for them. Criteria used for selection were the observed and expected heterozygosity and the Wright's F Statistics obtained in the simulations. The gene flow model selected was the isolation by distance model that used a rate of 0.1. We observed high levels of genetic differentiation among the fragments as result of their reproductive isolation. To allow homogenization of the allelic frequencies through gene flow, the solution would be to create ecological corridors with the aim of connecting distant fragments.

RESUMO: O fluxo gênico, cuja efetividade é função do modelo e da taxa, assume especial importância na conservação de recursos genéticos por permitir a conectividade de populações isoladas geograficamente, sujeitas à redução da variabilidade genética. O entendimento de como o fluxo gênico ocorre pode contribuir no planejamento de ações para a conservação e na seleção de populações prioritárias para uma eventual intervenção. Programas de simulação permitem inferir sobre eventos passados, a partir de dados atuais ou prever fenômenos futuros sob cenários genéticos reais. Fenômenos adversos podem ser previstos e medidas podem ser tomadas para contorná-los. O objetivo deste estudo foi identificar o modelo e a taxa de fluxo gênico que melhor explicam a estrutura genética de oito fragmentos da espécie arbórea florestal Cabralea canjerana, em desenvolvimento na região brasileira do bioma Mata Atlântica. Foram realizadas simulações com o programa EASYPOP usando dados de marcadores microssatélites obtidos por Melo e colaboradores, em 2012, 2014 e 2016, sendo testados cinco modelos e nove taxas de migração, selecionando-se o modelo que apresentou os valores mais próximos daqueles que foram publicados. Os critérios usados para a seleção do modelo foram a heterozigosidade observada e esperada e as estatísticas F de Wright obtidas nas simulações. O modelo de fluxo gênico entre os fragmentos foi o de isolamento por distância a uma taxa de 0.1. Foram observados elevados índices de diferenciação genética entre os fragmentos em decorrência do seu isolamento reprodutivo. Desse modo, sugere-se a construção de corredores ecológicos com vistas a conectar fragmentos distantes e, desta forma, permitir a homogeneização das frequências alélicas por meio do fluxo gênico.

Treatment of bilateral ovarian dysgerminoma with 11-year follow-up: A case report.

INTRODUCTION: Malignant ovarian germ cell tumors (MOGCTs) are rare malignancies with an incidence of about 0.5/100,000. They account for less than 5% of all ovarian tumors, of which 32.8% are dysgerminomas, the female analogue of seminomas. These tumors occur in all age groups, with peak incidence below the age of 20 years in women. AIM: To describe the case of a bilateral ovarian dysgerminoma treatment with 11-year follow-up. METHODS: Case report with details regarding clinical history, surgical treatment, chemotherapy and follow up. We include a brief literature review. RESULTS: The patient underwent radical surgery for an advanced dysgerminoma, 20 cm in length, that compromised the contralateral ovary and sigmoid. Neoplastic cells were found in ascitic fluid. Subsequently, she underwent adjuvant chemotherapy according to a standard protocol. She has survived disease-free for more than 11 years. CONCLUSIONS: Dysgerminoma is a malignant neoplasm that, similar to other cancers, is easier to treat when diagnosed early. However, cures may be obtained even in advanced cases.

A simple awareness campaign to promote food waste reduction in a University canteen.

Food waste has important environmental, social and economic impacts and increasing attention has been given lately to the unparalleled scale of food waste in the food supply chain worldwide. An initiative aiming to reduce food waste was tested at the School of Agriculture canteen (University of Lisbon, Portugal). The "Clean dish, clean conscience!" initiative consisted of a simple and inexpensive education campaign to raise awareness of reducing plate waste, by establishing the connection between food waste and personal behaviour. As a first stage plate waste from canteen users was measured over a 10 day period. After this period, a waste consumption index and per capita waste consumption were calculated to evaluate the level of satisfaction of the consumer and the related concern about food wastage, and was classified as Bad. After this first stage it was concluded that the users did not have strong convictions about avoiding food waste. During the second stage of the project an education campaign was implemented with plate waste being monitored for a further 16 days to assess the effectiveness of the campaign. The approach consisted of displaying simple and affordable informative posters in strategic areas of the canteen with simple messages reminding not to accept food they knew they would not eat. This led to a mean reduction in the waste consumption index of ∼15%. A parallel action encouraging separation of organic and inorganic waste was implemented as well, with an active participation of >70% of the users. The initiative achieved its objective of reducing plate waste by raising awareness of the daily food waste problem at the institution's canteen and by suggesting "how-to" actions for reducing such waste. This study showed how avoidable waste can be reduced simply by making students aware of the topic of food waste. Simple strategies may be useful to improve behaviours and increase sustainability of the canteens at Universities although this proved to be only efficient with the collaboration of the canteen staff that needs solid education. From the results, a set of measures was presented to the University Social Services for adoption to ensure a permanent reduction of food waste and recyclables in the University canteens.

Decomposition rate and enzymatic activity of composted municipal waste and poultry manure in the soil in a biofuel crops field.

BACKGROUND: Biofuel crops are gaining importance because of the need to replace non-renewable sources. Also, due to the increasing amounts of wastes generated, there is the need to recycle them to the soil, both to fertilize crops and to improve soil physical properties through organic matter increase and microbiological changes in the rhizosphere. We therefore studied the influence of six biofuel crops (elephant grass, giant cane, sugarcane, blue gum, black cottonwood, willow) on the decomposition rate and enzymatic activity of composted municipal solid waste and poultry manure. Organic amendments were incubated in the field (litterbag method), buried near each plant or bare soil. Biomass decrease and dehydrogenase, urease and acid phosphatase level in amendments was monitored over a 180-day period. Soil under the litterbags was analysed for the same enzymatic activity and organic matter fractions (last sampling). After 365 days, a fractionation of organic matter was carried out in both amendments and soil under the litterbags. RESULTS: For compost, willow and sugarcane generally led to the greatest enzymatic activity, at the end of the experiment. For manure, dehydrogenase activity decreased sharply with time, the smallest value near sugarcane, while phosphatase and urease generally presented the highest values, at the beginning or after 90 days' incubation. Clustering showed that plant species could be grouped based on biomass and enzymes measured over time. CONCLUSIONS: Plant species influenced the decomposition rate and enzymatic activities of the organic amendments. Overall, mineralization of both amendments was associated with a greater urease activity in soils. Dehydrogenase activity in manure was closely associated with urease activity. © 2016 Society of Chemical Industry.

Formação em saúde bucal e Clínica Ampliada: por uma discussão dos currículos de graduação / Formation in oral health and Extended General Practice: for a discussion of undergraduate curricula

Na perspectiva de compreender percursos de formação e suas interfaces com os processos de trabalho no Sistema Único de Saúde (SUS), este artigo objetiva analisar as experiências vividas por estudantes de Odontologia em um estágio extracurricular no serviço de saúde no município de São Paulo. Tratase de estudo descritivo-exploratório de abordagem qualitativa, cujos sujeitos foram três estudantes de graduação em Odontologia, inseridos em um estágio em Clínica Ampliada que registraram suas experiências em diários de pesquisa. O material coletado foi trabalhado por análise de conteúdo temática. No período de maio a dezembro de 2015, foram atendidos - na Clínica Ampliada de saúde bucal da Unidade Básica de Saúde (UBS) - em média, 16 usuários por estagiário, número aproximado à quantidade de pacientes que um aluno de Odontologia da mesma Instituição de Educação Superior (IES) comumente atende durante sua graduação. A partir do conteúdo dos diários dos estagiários, percebe-se a existência de uma forte dissociação entre as vivências dos estudantes no espaço da pesquisa e suas experiências nos ambulatórios da IES. Apesar de passada mais de uma década desde a homologação das Diretrizes Curriculares Nacionais (DCN) para os cursos da área da saúde, e dos esforços para mudar o perfil profissional, persiste o distanciamento entre conteúdos e abordagens da graduação em saúde e os processos de trabalho no SUS. Por certo, o desafio reside também na efetividade da integração curricular, na diversificação de cenários de aprendizagem e na articulação com o SUS. As experiências vividas pelos estagiários revelam as diferenças profundas e arraigadas da prática odontológica nos cenários de ensino e no SUS (AU).

This study aimed to analyze the experiences of dental students on internship in an oral health public service in the city of São Paulo, Brazil. For this descriptive-exploratory study with a qualitative approach, the subjects were three undergraduate students in dentistry, inserted in a stage in an extended clinic that recorded their experiences in research journals. The collected material was worked by thematic content analysis. From May to December 2015, 16 patients were attended in the extended general practice, a higher number when compared with the number of patients that a dental student attends throughout their graduation. There is a real distance between contents and approaches of undergraduate health and the work processes in the public health service. The challenge also lies in the effectiveness of curricular integration, in the diversification of learning scenarios and articulation with public health. The experiences of trainees reveal the profound and deeply rooted differences in dental practice in school compared to the public service, in the Extended General Practice (AU).

Apple Aminoacid Profile and Yeast Strains in the Formation of Fusel Alcohols and Esters in Cider Production.

The amino acid profile in dessert apple must and its effect on the synthesis of fusel alcohols and esters in cider were established by instrumental analysis. The amino acid profile was performed in nine apple musts. Two apple musts with high (>150 mg/L) and low (<75 mg/L) nitrogen content, and four enological yeast strains, were used in cider fermentation. The aspartic acid, asparagine and glutamic acid amino acids were the majority in all the apple juices, representing 57.10% to 81.95%. These three amino acids provided a high consumption (>90%) during fermentation in all the ciders. Principal component analysis (PCA) explained 81.42% of data variability and the separation of three groups for the analyzed samples was verified. The ciders manufactured with low nitrogen content showed sluggish fermentation and around 50% less content of volatile compounds (independent of the yeast strain used), which were mainly 3-methyl-1-butanol (isoamyl alcohol) and esters. However, in the presence of amino acids (asparagine, aspartic acid, glutamic acid and alanine) there was a greater differentiation between the yeasts in the production of fusel alcohols and ethyl esters. High contents of these aminoacids in dessert apple musts are essential for the production of fusel alcohols and most of esters by aromatic yeasts during cider fermentation.

Molecular Characterization of Trypanosoma cruzi Tc8.2 Gene Indicates Two Differential Locations for the Encoded Protein in Epimastigote and Trypomastigote Forms

This report describes the molecular characterization of the Tc8.2 gene of Trypanosoma cruzi. Both the Tc8.2 gene and its encoded protein were analyzed by bioinformatics, while Northern blot and RT-PCR were used for the transcripts. Besides, immunolocalization of recombinant protein was done by immunofluorescence and electron microscopy. Analysis indicated the presence of a single copy of Tc8.2 in the T. cruzi genome and 2-different sized transcripts in epimastigotes/amastigotes and trypomastigotes. Immunoblotting showed 70 and 80 kDa polypeptides in epimastigotes and trypomastigotes, respectively, and a differential pattern of immunolocalization. Overall, the results suggest that Tc8.2 is differentially expressed during the T. cruzi life cycle.
