ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

ABSTRACT Bases are chemical species that donate electrons, accept protons, or release hydroxyls (OH–) in aqueous solution. In Soil Science, “base saturation”, “exchangeable bases” or “basic cations” has been widely used to distinguish Ca2+, Mg2+, Na+, and K+ from H+ and Al3+ cations. This terminology is confusing since none of these cations are truly a base in chemistry sense. However, in the absence of the proposition of a correct term, the term “base saturation” remains in use nowadays, causing confusion among students, professionals, and even among professors and researchers in Soil Science, as it leads to the erroneous interpretation that the soil acidity can be corrected by adding these cations to the soil. Here, we present the historical background of this nomenclature and a theoretical foundation that justifies the abolition of the use of these terms in Soil Science. We consider that the most correct is to call it “Ca-Mg-K-Na saturation”, which, despite being long, would refer directly and without any misinterpretation of the terminology. In Soil Fertility, the “base saturation” is often calculated only as a function of the sum of Ca, Mg, and K, since the Na content is negligible in most tropical and subtropical soils. Thus, one could use the term “Ca-Mg-K saturation”. Likewise, it is also suggested to abolish the use of the term “sum of bases” and use the term “sum of Ca-Mg-K” or “sum of Ca-Mg-K-Na” instead when necessary.

ABSTRACT Background: Rickettsia of the spotted fever group (SFG) has been reported in ticks and domestic animals in Campo Grande (CG), Midwest Brazil. Methods: We searched for Rickettsia in the SFG in capybaras and their ticks in an urban park in the CG. Results: The seropositivity rate was 88.2% (15/17). Although 87.7% of the capybaras sampled showed infestations with Amblyomma sculptum, A. dubitatum, and Amblyomma spp., no molecular results were detected in ticks. Conclusions: Since Rickettsia from the SFG circulates among capybaras in the urban parks of Campo Grande, this large rodent species should be monitored within the One Health Agenda.

Abstract BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency band 980 MHz - 1260 MHz, corresponding to a redshift range 0.127 < z < 0.449. BAO is one of the most powerful probes of cosmological parameters and BINGO was designed to detect the BAO signal to a level that makes it possible to put new constraints on the equation of state of dark energy. The telescope will be built in Paraíba, Brazil and consists of two \thicksim 40m mirrors, a feedhorn array of 50 horns, and no moving parts, working as a drift-scan instrument. It will cover a 15 ^{\circ} ∘ declination strip centered at \sim \delta ∼ δ =-15 ^{\circ} ∘, mapping \sim ∼ 5400 square degrees in the sky. The BINGO consortium is led by University of São Paulo with co-leadership at National Institute for Space Research and Campina Grande Federal University (Brazil). Telescope subsystems have already been fabricated and tested, and the dish and structure fabrication are expected to start in late 2020, as well as the road and terrain preparation.

RESUMO Essa pesquisa teve por finalidade avaliar um resíduo de lodo de efluentes de indústrias de papel quanto à potencialidade de emprego em matrizes cimentícias. Verificou-se a composição química do resíduo e realizaram-se misturas com adições de 0, 5 e 10%, em relação à massa de cimento. As matrizes cimentícias foram analisadas por meio de calorimetria isotérmica, resistência à compressão, resistência à tração na compressão diametral, absorção de água por capilaridade, densidade de massa aparente e módulo de elasticidade dinâmico. Os resultados obtidos não foram satisfatórios, visto que a adição do resíduo à matriz apresentou aumento no consumo de cimento para atingir a resistência requerida e aumento no consumo de água para manutenção da consistência.

ABSTRACT The purpose of this study was to evaluate a paper sludge waste obtained from tissue paper industries regarding its potential for use in cementitious materials. The chemical composition of the waste was assessed and mixtures were made with 0%, 5% and 10% additions of the material, by mass of cement. The cement matrices were analysed experimentally by isothermal calorimetry, compressive strength and tensile strength by diametric compression, water absorption by capillarity, apparent mass density and dynamic modulus of elasticity. The results obtained were not satisfactory, since the addition of the paper sludge waste showed an increase in the cement consumption to reach the required compressive strength, as well as a rise in water consumption in order to maintain the mortar consistency.

ABSTRACT Initiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management and protection of wetlands and natural resources, as well as reveal knowledge gaps regarding aquatic plants and wetlands. Furthermore, such initiatives can contribute directly to consolidating wetland classification systems in Brazil. The objectives of this work are to present and explore the use of a data repository and online platform created specifically for the management of data on aquatic plants in Brazil. The data repository for aquatic plants was developed to store information on species occurrence records in a standardized form considering: systematics, taxonomy, habit, life form, geographic distribution, hydrographic basin, wetland, bibliographic references and herbarium material. A total of 3,903 records referring to the Southeast Region of Brazil were generated for the data repository. This total encompassed 1,036 species distributed among 132 families and 466 genera. Our results illustrate the diversity of information available regarding aquatic plants, circumscribe this group of species and serve as a source of data about them. Similar databases and electronic infrastructures can be developed for other flora in the future.

RESUMO: Objetivo: Analisar as prevalências dos níveis de colesterol total e frações alterados na população brasileira, segundo dados bioquímicos da Pesquisa Nacional de Saúde. Métodos: Estudo descritivo, utilizando dados laboratoriais da Pesquisa Nacional de Saúde coletados entre os anos de 2014 e 2015. Foram analisados exames de colesterol total e frações e calculadas prevalências populacionais de valores alterados segundo variáveis sociodemográficas. Consideraram-se os seguintes pontos de corte: colesterol total ≥ 200mg/dL; lipoproteínas de baixa densidade (LDL) ≥ 130mg/dL e lipoproteínas de alta densidade (HDL) < 40mg/dL. Resultados: Aprevalência de colesterol total ≥ 200mg/dL na população foi de 32,7%, mais elevada em mulheres (35,1%). A prevalência de HDL alterado foi de 31,8%, sendo de 42,8% no sexo masculino e 22,0% no feminino. LDL≥ 130mg/dL foi observado em 18,6%, com prevalência mais elevada em mulheres (19,9%). População com idade de 45 anos ou mais e com baixa escolaridade apresentou maiores prevalências de colesterol com alterações. Conclusão: Valores de colesterol total e frações alterados foram frequentes na população brasileira, especialmente entre mulheres, idosos e pessoas de baixa escolaridade. Esses resultados poderão orientar as ações de controle e prevenção, como alimentação saudável, atividade física e tratamento, visando à prevenção de doenças coronarianas.

ABSTRACT: Objective: To analyze the prevalence of altered total cholesterol and fractions levels in the Brazilian population, according to biochemical data from the National Health Survey. Methods: A descriptive study, using data from the National Health Survey, collected between 2014 and 2015. Total cholesterol and fractions were analyzed and population prevalences of altered values according to socio-demographic variables were calculated. The cutoff points considered were: total cholesterol ≥ 200mg/dl; low-density lipoprotein LDL ≥ 130mg/dL and high-density lipoprotein HDL < 40mg/dL. Results: The prevalence of total cholesterol ≥200mg/dL in the population was 32.7%, and higher in women (35.1%). The prevalence of altered HDL was 31.8%, 22.0% in females and 42.8% in males. LDL ≥ 130mg/dL was found in 18.6% and was higher in women (19.9%). The population aged 45 years old and older and those with low levels of education presented a higher prevalence of altered cholesterol. Conclusion: Altered values of total cholesterol and fractions were frequent in the Brazilian population, especially among women, the elderly and people with low levels of education. These results may guide control and preventative actions such as healthy eating, physical activity and treatment, all of which aim to prevent coronary diseases.

ABSTRACT The objective of this study was to determine the apparent digestibility coefficients of energy, protein, and amino acids in protein ingredients by pirarucu juveniles. A test was conducted with six protein ingredients: meat and bone meal, fish meal, hydrolyzed feather meal, poultry by-product meal, soybean meal, and corn gluten meal. Three repetitions were used for each tested ingredient. A reference feed was used with 430 g kg−1 crude protein and 19.63 kJ g−1 gross energy. The test feeds consisted of the replacement of 30% of the reference feeds with the test ingredients. Chromium oxide was added to the feeds at 1 g kg−1 as an external marker. Eighteen juveniles with an average weight of 235±36 g were used. The best apparent digestibility coefficients of protein were found for fish meal, followed by the poultry by-product meal and meat and bone meal. However, except for gluten, all the tested ingredients presented protein digestibilities above 0.70. The crude energy apparent digestibility coefficient was higher for animal ingredients, above 0.75, than for vegetable ingredients, which presented values below 0.60. Pirarucu efficiently uses the protein from the tested ingredients, regardless of origin. However, it has a preferential ability to use the energy from animal ingredients.

RESUMO O crescimento da aquicultura brasileira tem estimulado o desenvolvimento da cadeia produtiva de espécies nativas, incluindo de ambiente marinho. Objetivou-se, neste estudo, avaliar o desempenho dos juvenis de carapeba (Diapterus rhombeus) alimentados com rações contendo diferentes concentrações de proteína bruta (32, 36, 40 e 44 g 100 g-1), caracterizando um delineamento inteiramente casualizado, com quatro tratamentos e quatro repetições. Foram distribuídos 80 juvenis (7,2 ± 1,5 g) de carapeba em 16 tanques circulares (150 L). Os peixes foram alimentados quatro vezes ao dia. Após 60 dias, foram avaliados o peso final, o consumo de ração, o ganho de peso (GP), a conversão alimentar (CA), a taxa de eficiência proteica (TEP), a taxa de eficiência energética, o crescimento específico, a taxa de sobrevivência e a composição corporal dos peixes. Verificou-se efeito significativo do nível de proteína com o melhor valor de GP obtido com 38,20 g 100 g-1 de proteína bruta. Para a CA, o melhor valor estimado ocorreu com 38,06 g 100 g-1 de proteína bruta, próximo ao observado para o TEP (38,91 g 100 g-1). Os demais parâmetros de desempenho e de composição corporal não foram influenciados pelos níveis de proteína bruta. As concentrações de proteína bruta na dieta entre 38,06 e 38,91 g 100 g-1 promovem os melhores índices de desempenho de juvenis de carapeba.

ABSTRACT The growth of the Brazilian aquaculture has stimulated the development of the productive chain of native species, including marine environment. The objective of this study was to evaluate the growth performance of juvenile mojarra fish (Diapterus rhombeus) fed diets containing different concentrations of crude protein (32, 36, 40 and 44 g 100 g-1). The 80 juvenile mojarra (7.2±1.5 g) were kept in 16 circular tanks (150 L). The study design used was completely randomized with four treatments and four repetitions. The fish were fed four times a day. At the end of the experiment (60 days) the final weight, feed intake, weight gain (WG), feed:gain ratio (FGR), protein efficiency rate (PER), energy efficiency rate, specific growth, survival rate and, body composition were evaluated. It was verified significant effect of protein level on the WG, with the best value at the level of 38.20 g 100 g-1 of crude protein. For FGR, the best estimated value occurred with 38.06 g 100 g-1 of crude protein, similar to that reported for the PER (38.91 g 100 g-1). The other performance parameters and body composition were not influenced by crude protein levels. Diet crude protein concentrations between 38.06 and 38.91 g 100 g-1 provide the best performance indices for juvenile mojarra.

An understanding of feed ingredient digestibility for the pirarucu is a fundamental step in the development of feeds that promote proper growth of the specie while in captivity. A digestibility trial was conducted with four treatments in triplicate (corn starch, corn, rice bran and wheat bran) to evaluate the digestibility of dry matter, gross energy, crude protein and amino acids by the pirarucu. We used indirect methodology with the inclusion of chromium oxide at 0.1% in the feeds. In total, 18 juveniles were used, with an average live weight of 235 ± 36 g. The sampled juveniles were trained to consume the feeds prior to testing. The corn and cornstarch presented the best apparent digestibility coefficients (ADCs) of dry matter, with 76.37% and 70.66%, respectively, followed by rice bran (46.23%) and wheat bran (45.13%). The best ADCs of crude protein were observed in corn (93.44%) and cornstarch (90.94%) compared to rice bran (68.23%) and wheat bran (68.58%). There was no significant difference in the ADC of gross energy; the values ranged from 47.10% for corn starch to 40.10% for corn. The corn and corn starch presented the best ADCs for all the amino acids evaluated, followed by rice bran and wheat bran.

El conocimiento de la digestibilidad de los ingredientes en la alimentación del pirarucu es primordial para la elaboración de pienso específico, que promueva un crecimiento óptimo. Se realizó un ensayo de digestibilidad con cuatro ingredientes energéticos, almidón de maíz, harina de maíz, salvado de arroz y salvado de trigo para la evaluación de las digestibilidades de materia seca, energía bruta, proteína bruta y aminoácidos. Se utilizaron 18 juveniles con peso de 235 ± 36 g. La harina de maíz y el almidón de maíz presentan los mejores coeficientes de digestibilidad aparente (CDA) de la materia seca, 76,37% y 70,66% respectivamente, seguidos por el salvado de arroz (46,23%) y salvado de trigo (45,13%). Los mejores CDA de la proteína bruta se determinaron para harina de maíz (93,44%) y almidón de maíz (90,94%), en relación al salvado de arroz (68,23%) y salvado de trigo (68,58%). Para el CDA de la energía bruta no fue registrada diferencia estadística, variando entre 47,10% para el almidón de maíz y a 40,10%, para la harina de maíz. La harina de maíz y el almidón de maíz presentaron los mejores CDA de todos los aminoácidos evaluados, seguidos por el salvado de arroz y salvado de trigo.

Objetivou-se avaliar o desempenho zootécnico e a composição corporal de juvenis de tambacu alimentados com rações contendo níveis crescentes de celulose. 128 juvenis de tambacu (29,0±6,0g) foram distribuídos em 16 tanques (150 L), na densidade de oito exemplares por tanque, em um delineamento inteiramente casualizado com quatro tratamentos (níveis crescentes de celulose: 0; 20; 40 e 60 g kg-1) e quatro repetições. Os parâmetros de desempenho avaliados foram: peso final (PF), consumo de ração (CR), ganho de peso (GP), conversão alimentar aparente (CAA), taxa de eficiência proteica (TEP) e sobrevivência (SOB). Para a análise de composição corporal, foram analisados matéria seca (MS), proteína bruta (PB), extrato etéreo (EE), energia bruta (EB) e matéria mineral (MM). Verificou-se comportamento quadrático (P<0,05) para as variáveis PF, CR, GP e CAA com os melhores resultados obtidos, respectivamente, para os níveis de 19,95; 11,22; 19,87 e 23,86 g kg-1 de inclusão da celulose nas rações. Não houve efeito (P>0,05) dos níveis de inclusão da celulose sobre a TEP, SOB e sobre os parâmetros de composição corporal MS, PB, EE, EB e MM. As rações com maiores níveis de inclusão da celulose afetaram negativamente o desempenho de juvenis de tambacu, no entanto, as modificações fisiológicas e metabólicas provocadas por essas rações não foram suficientes para afetar a composição corporal.

Aimed to evaluate the growth performance and body composition of juvenile tambacu fed diets containing increasing levels of cellulose. 128 juveniles (29.0±6.0g) were distributed into 16 tanks (150 L), at a density of eight fish per tank, in a completely randomized design with four treatments (increasing levels of cellulose: 0, 20, 40 and 60 g kg-1) and four replications. For the growth performance parameters it was evaluated: final weight (FW), feed intake (FI), weight gain (WG), feed conversion rate (FCR), protein efficiency rate (PER) and survival (SUR). For the analysis of body composition, dry matter (DM), crude protein (CP), ether extract (EE), gross energy (GE) and mineral matter (MM) were analyzed. There was a quadratic response (P<0.05) to the FW, FI, WG and FCR variables with the best results obtained, respectively, to levels of 19.95, 11.22, 19.87 and 23.86 g kg-1 of inclusion of cellulose in the rations. There was no effect (P>0.05) of levels of inclusion of cellulose on the PER, SUR and on the parameters of body composition in DM, CP, EE, GE and MM. Diets with high inclusion levels of cellulose adversely affected the performance of juvenile tambacu. However, the physiological and metabolic changes caused by these rations were not sufficient to affect body composition.

Descrevemos quatro casos de fraturas femorais atípicas atendidos no Serviço de Endocrinologia do Hospital de Clínicas da Universidade Federal do Paraná (SEMPR/UFPR) que, apesar de característicos desse tipo de fratura, apresentam peculiaridades clínicas que devem ser consideradas e servir de alerta nesses pacientes, tais como: diagnóstico tardio com manutenção do uso de bisfosfonatos; ausência de comorbidades associadas com resolução sem sequelas; falha na consolidação da fratura; uso de medicação anabólica após a fratura e acompanhamento com marcadores de remodelação óssea.

We describe four cases of atypical femoral fractures treated at the Department of Endocrinology, Hospital de Clínicas, Federal University of Paraná (SEMPR) which, although characteristic of this type of fracture, presented clinical peculiarities that should be considered and serve as a warning in these patients, such as: late diagnosis with maintenance of bisphosphonates; absence of co-morbidities with excellent result; failure of fracture healing; use of anabolic medication after the fracture and the use of bone turnover markers at the follow up.

O café é um dos principais produtos agrícolas, sendo considerado o segundo item em importância do comércio internacional de "commodities". O gênero Coffea pertence à família Rubiaceae que também inclui outras plantas importantes. Este gênero contém aproximadamente 100 espécies, mas a produção comercial é baseada somente em duas espécies, Coffea arabica e Coffea canephora, que representam aproximadamente 70 % e 30 % do mercado total de café, respectivamente. O Projeto Genoma Café Brasileiro foi desenvolvido com o objetivo de disponibilizar os modernos recursos da genômica à comunidade científica e aos diferentes segmentos da cadeia produtiva do café. Para isso, foram seqüenciados 214.964 clones escolhidos aleatoriamente de 37 bibliotecas de cDNA de C. arabica, C. canephora e C. racemosa representando estádios específicos do desenvolvimento de células e de tecidos do cafeeiro, resultando em 130.792, 12.381 e 10.566 seqüências de cada espécie, respectivamente, após processo de trimagem. Os ESTs foram agrupados em 17.982 contigs e em 32.155 singletons. A comparação destas seqüências pelo programa BLAST revelou que 22 % não tiveram nenhuma similaridade significativa às seqüências no banco de dados do National Center for Biotechnology Information (de função conhecida ou desconhecida). A base de dados de ESTs do cafeeiro resultou na identificação de cerca de 33.000 unigenes diferentes. Os resultados de anotação das seqüências foram armazenados em base de dados "online" em <A HREF="http://www.lge.ibi.unicamp.br/cafe">http://www.lge.ibi.unicamp.br/cafe</A>. Os recursos desenvolvidos por este projeto disponibilizam ferramentas genéticas e genômicas que podem ser decisivas para a sustentabilidade, a competitividade e a futura viabilidade da agroindústria cafeeira nos mercados interno e externo.

Coffee is one of the most valuable agricultural commodities and ranks second on international trade exchanges. The genus Coffea belongs to the Rubiaceae family which includes other important plants. The genus contains about 100 species but commercial production is based only on two species, Coffea arabica and Coffea canephora that represent about 70 % and 30 % of the total coffee market, respectively. The Brazilian Coffee Genome Project was designed with the objective of making modern genomics resources available to the coffee scientific community, working on different aspects of the coffee production chain. We have single-pass sequenced a total of 214,964 randomly picked clones from 37 cDNA libraries of C. arabica, C. canephora and C. racemosa, representing specific stages of cells and plant development that after trimming resulted in 130,792, 12,381 and 10,566 sequences for each species, respectively. The ESTs clustered into 17,982 clusters and 32,155 singletons. Blast analysis of these sequences revealed that 22 % had no significant matches to sequences in the National Center for Biotechnology Information database (of known or unknown function). The generated coffee EST database resulted in the identification of close to 33,000 different unigenes. Annotated sequencing results have been stored in an online database at <A HREF="http://www.lge.ibi.unicamp.br/cafe">http://www.lge.ibi.unicamp.br/cafe</A>. Resources developed in this project provide genetic and genomic tools that may hold the key to the sustainability, competitiveness and future viability of the coffee industry in local and international markets.
