Uma das propensões do mercado e da saúde pública é a elaboração de produtos com maior número de componentes de origem natural, principalmente de origem vegetal, analisando de forma racional a biodiversidade brasileira. Sendo que os danos causado a pele pela radiação ultravioleta (R-UV) podem ser evitados com o uso de substâncias denominadas filtros solares, encontrados em formulações tópicas, cujo fator de proteção solar (FPS) pode ser mensurado espectrofotometricamente. Esta pesquisa teve como objetivo avaliar o FPS e a atividade antioxidante da fase clorofórmica de Praxelis clematidea, através do teste in vitro. A partir de diluições da fase realizou-se análises por espectrofotometria de varredura na região do ultravioleta (290 – 320 nm) e determinação do FPS pelo método espectrofotométrico de Mansur et al. (1986). Para o teste de atividade quelante de íons ferro utilizou o método de Dinis et al. (1994), sendo a absorbância medida a 562 nm em espectrofotômetro e os resultados expressos em percentual (%). Assim, pode-se observar que todas as concentrações testadas (50 a 100 µg.mL-1) apresentaram potencial de fotoproteção com variação de FPS de 6,30 a 21,47, respectivamente. Como também, o extrato apresentou potencial antioxidante significativo, chegando a 68,66% na concentração de 1000 µg/mL o que pode favorecer o combate ao fotoenvelhecimento. Por isso, esses resultados sugerem que a fase clorofórmica de Praxelis clematidea apresenta potencial efeito fotoprotetor e antioxidante.

Resumo:Objetivo: Este estudo teve como objetivo analisar a correlação dos indicadores antropométricos com a pressão arterial de repouso (PA) em homens e mulheres sedentárias, e comparar a presença de risco entre os sexos a partir dos diferentes indicadores. Métodos: Participaram deste trabalho 420 indivíduos (203 homens e 217 mulheres), frequentadores de academia de ginástica com idade entre 18 e 35 anos. Os indicadores antropométricos avaliados foram: IMC (Índice de Massa Corporal), IC (Índice de Conicidade), CC (Circunferência da Cintura) e RCEst (Relação Cintura Estatura). A PA foi verificada no momento de repouso. A presença de risco cardíaco (RC) foi verificado a partir dos pontos de corte de cada indicador antropométrico por sexo. A correlação entre os indicadores antropométricos com a PA foi indicada através do teste de correlação linear de Pearson. Para a comparação da influência do sexo para identificação de RC, foi utilizado o teste de qui-quadrado. Adotou-se uma significância de 95% de confiança (p

Este trabalho teve como objetivo avaliar a percepção de consumidores em relação à higiene na comercialização de produtos cárneos na feira livre do bairro Heliópolis, na cidade de Garanhuns, Pernambuco. Para tanto, foi realizada uma pesquisa de caráter quantitativo, quando foram aplicados 50 questionários aos consumidores da feira. Os dados obtidos foram tabulados e analisados por meio da estatística descritiva. Os resultados revelaram que os consumidores estavam cientes que a forma de comercialização na feira livre era precária, com deficiências no aspecto higiênicossanitário, desde a obtenção da matéria-prima, acondicionamento, manipulação e transporte dos alimentos. Metade dos pesquisados (50%) apresentaram uma escolaridade elevada. Contudo, isto não influenciou no hábito em frequentar a feira, uma vez que, independentemente da escolaridade, todos (100%) concordaram com a continuidade desta forma de comercialização dos produtos cárneos. Apesar de relatarem disposição em pagar um valor mais elevado por um produto de melhor qualidade, a influência cultural é responsável pelo hábito em frequentar a feira semanalmente e adquirir tais produtos. Esta forma de comercialização representa riscos à saúde do consumidor, o que constitui um problema de saúde pública, que deve sofrer intervenção por parte dos órgãos fiscalizadores. A população deve ser alertada sobre tais riscos, enquanto os comerciantes, capacitados sobre os diversos aspectos relacionados a manipulação segura dos alimentos comercializados.

ResumoOBJETIVOS: Comparar, entre diferentes faixas etárias e sexo, a flexibilidade (FLEX) de usuários de parque de lazer com diferentes níveis de atividade física (NAF). METODOLOGIA: A amostra foi composta por 79 indivíduos com idade de 48,3±15,9 anos e índice de massa corporal (IMC) de 25,0±4,2 kg/m2, os quais responderam ao Questionário Internacional de Atividade Física (IPAQ). A FLEX foi mensurada pelo teste de sentar-e-alcançar (Banco de Wells). A amostra foi dividida em estratos de ativos (n=55) e inativos (n=24). Além do NAF, os grupos foram divididos pela faixa etária e sexo. Estatística descritiva e o Teste t de Student foram adotados com nível de significância de p0,05). As mulheres demonstraram com o avançar da idade, redução de 10,1% para as inativas e 13,4% para as ativas (p>0,05). Ao analisar o Δ% da FLEX verificou-se maior redução para os homens em comparação às mulheres inativas (43,9% vs. 10,1%; p=0,03) e ativas (36,1% vs. 13,4%; p=0,02). Ao comparar a FLEX entre diferentes NAF´s no mesmo sexo e idade não ocorreram diferenças em nenhum dos grupos (p>0,05). CONCLUSÃO: A FLEX foi influenciada pela idade e sexo, mas não pelo NAF em usuários de parque de Lazer. As mulheres, independente da faixa etária, apresentam níveis superiores da FLEX em relação aos apresentados pelos homens.Palavras-chave: flexibilidade; nível de atividade física; sexo; idade.AbstractOBTECTIVE: To compare, between different age groups and sex, flexibility (FLEX) leisure park users with different physical activity levels (PAL). METHODOLOGY: The sample consisted of 79 subjects aged 48.3 ± 15.9 years and body mass index (BMI) of 25.0 ± 4.2 kg.m-1 who completed the International Physical Activity Questionnaire (IPAQ). The FLEX was measured by the sit-and-reach. The sample was divided into groups of active (n = 55) and inactive (n = 24). Besides the PAL, the groups were also divided by age group and sex. Descriptive statistics and Student t test were adopted with a significance level of p < 0.05. RESULTS: When calculated the percentage change (Δ%) of FLEX between age groups and genders, men demonstrated with advancing age, decreased from 43.9% to inactive and 36.1% to active (p> 0.05). Women demonstrated with advancing age, decreased from 10.1% to inactive and 13.4% to active (p> 0.05). By analyzing the Δ% of FLEX there was greater reduction for men compared to inactive women (43.9% vs. 10.1%, p = 0.03) and active (36.1% vs. 13.4 %, p = 0.02). Comparing FLEX between different PAL, the same gender and age there were no differences in either group (p> 0.05). CONCLUSION: The FLEX was influenced by age and sex, but not by the NAF in users leisure park. The women, regardless of age, have higher levels of FLEX compared to those presented by men. figshare DOI: 10.6084/m9.figshare.9788732

ResumoObjetivo: Revisar sistematicamente os efeitos do treinamento resistido (TR) sobre a aptidão aeróbia de idosos saudáveis. Procedimentos metodológicos: Foi realizada busca nas bases de dados do Pubmed, Lilacs e Scielo, sem limite de data, com os seguintes descritores: "strength training”, “weight training”, "resistance training", "aerobic fitness", "aerobic power”, "VO2", "elderly", and "older”. Dos 60 estudos inicialmente acessados, 51 foram excluídos por não atenderem aos critérios estabelecidos na presente revisão. Dos 9 estudos restantes, 4 foram selecionados a partir das referências de outras investigações, totalizando 13 estudos analisados. Síntese dos dados: Dos estudos analisados, 54% obtiveram resultados positivos em relação aos efeitos do TR na aptidão aeróbia de idosos saudáveis. Ao analisar o viés individual de cada estudo, foi possível verificar que, com exceção da randomização adequada, realizada em 91,6% dos estudos, outros critérios metodológicos não foram satisfatórios na totalidade dos estudos, entre eles a ocultação da alocação (8,3%), o cegamento de avaliados e pesquisadores (0%), o cegamento de avaliadores do desfecho (0%), a descrição de perdas e exclusões (62%) e a análise de intenção de tratar (53,8%). Conclusões: Estes resultados sugerem a necessidade de investigações que atendam aos critérios metodológicos supradescritos, visando fornecer resultados que permitam conclusões mais seguras. Embora ocorra falta de consenso na literatura, bem como os critérios metodológicos dos estudos analisados limitam possíveis conclusões, o TR parece desempenhar importante papel no incremento da aptidão aeróbia de idosos saudáveis.Palavras-chave: Treinamento de Força; Capacidade Aeróbia; Envelhecimento. AbstractObjective: To review systematically the effects of resistance training (RT) on the aerobic fitness of healthy elderly. Methodological procedures: A search was performed in the Pubmed, Lilacs and Scielo databases, no date limit, with the following descriptors: "strength training", "weight training", "resistance training", "aerobic fitness", "aerobic power", "VO2", "elderly", and "older". Of the 60 studies initially accessed, 51 were excluded for not meeting the criteria set out in this review. Of the remaining 9 studies, 4 were selected from references from other investigations totaling 13 studies analyzed. Summary of the findings: Of the studies analyzed, 54% had positive results regarding the effects of TR in aerobic fitness of healthy elderly. Analyzing the individual bias of each study, we found that with the exception of randomization appropriate, carried out in 91.6% of the studies, other methodological criteria were not satisfactory in all studies, including the concealment of allocation (8.3%), the blinding evaluated and researchers (0%), blinding assessors outcome (0%), the description losses and deletions (62%) and the analysis of intention to treat (53.8%). Conclusions: These results suggest the need for research that meet the above methodological criteria, aiming at providing results that allow safer conclusions. Although it occurs lack of consensus in the literature as well as the methodological criteria of the studies analyzed limit possible conclusions, the TR may play an important role in increasing the aerobic fitness of healthy elderly.Keywords: Strength Training; Aerobic capacity; Aging. figshare DOI: 10.6084/m9.figshare.9788798

O estudo avaliou a manifestação de estro, taxa de prenhez e parição em cabras leiteiras utilizando um dispositivo intravaginal a base de progesterona natural (CIDR®) após duas e três utilizações. Para tanto, foram utilizadas cabras nulíparas e pluríparas divididas em dois grupos experimentais de sincronização de estro, CIDR® reutilizado 01 vez (n=37) e CIDR® reutilizado 02 vezes (n=28). As fêmeas de todos os grupos receberam o mesmo tratamento hormonal com o emprego do dispositivo vaginal por cinco dias associado à aplicação intramuscular de um análogo de prostaglandina F2α (75µg) e a bioestimulação pelo efeito macho na retirada dos dispositivos. O intervalo entre a retirada do dispositivo e o início do estro foi de 31,06 ± 11,27 h para as nulíparas e de 61,05 ± 19,53 h para as pluríparas do grupo CIDR® reutilizado uma vez (P

Introduction: Moderate consumption of red wine (RW) has been associated with a decrease in cardiovascular risk due to its phenolic composition. Purpose: Assessing the effects of consuming different doses of RW on the blood pressure (BP) of men during 24 hours after its ingestion. Methods: 10 normotensive male subjects (25.1±3.6 years) consumed three different doses of RW (250ml, 200ml and 150ml) randomly for three weeks; one dose was ingested per week. The BP was measured by using the Ambulatory BP Monitoring every 15 minutes during waking, and every 30 minutes during the sleep period for 24 hours. Results: There was a reduction in mean values of Systolic Blood Pressure (SBP) from six to nine hours of waking period, and the Diastolic Blood Pressure (DBP) from nine to 12 hours of sleep compared with BP at rest. Conclusions: The moderate RW consumption significantly reduced SBP and DBP in men, with a 150ml dose sufficient to reduce and maintain better BP levels.

The aim of this study was to assess the effectiveness of cashew nut shell liquid (CNSL), Cordia verbenacea and Psidium guajava, both alone and in association against Rhipicephalus microplus. Larval packet and adult immersion tests were conducted in concentrations ranging from 3.1 at 100.0mg mL?1. CNSL was effective against engorged females (99.6%) at 100.0mg mL?1 and against larvae (99.2 %) at 50.0mg mL?1. The highest efficacy on engorged females was achieved by the essential oils of P. guajava at 12.5mg mL?1 (99.9%), followed by those of C. verbenacea at 25.0mg mL?1 (96.9%), while a low larvicidal activity of 5.8 and 59.0% was, respectively, obtained. The association at 50.0mg mL?1 had asignificant effect on both life stages of R. microplus. This association caused considerable larval mortality (95.3%) and high efficacy on engorged females (93.9%). Made available in DSpace on 2019-04-17T01:11:55Z (GMT).

The objective of this study was to compare the emissions of nitrous oxide (N2O) resulting from the application of nitrogen (N) and potassium (K) doses in fertigated sugarcane, in comparison to emissions from conventional fertilizer application. The study was conducted in the experimental area of Embrapa Mid-North, Teresina, Piauí state, Brazil, from August 2014 to January 2015. The experimental design was in randomized blocks, analyzed in a (2 x 2) +1 factorial scheme, with four replicates. The treatments consisted of the combination of two doses of N and K2O (60-120 and 120-180 kg ha-1, respectively) and two methods of application (in soil and fertigation), and a control. The use of fertigation reduced the emissions of N2O in sugarcane compared with the crop under conventional fertilization. Increase in N dose from 60 to 120 kg ha-1 applied through fertigation did not affect N2O emissions, while 60 and 120 kg ha-1 applied in the soil led to 40.6 and 50.2% increases in N2O emissions, respectively. The application of 60 and 120 kg ha-1 of N in the soil led to higher N2O emission factor, being 1.39 and 2.08% higher than in the crop fertigated with 60 and 120 kg ha-1 of N, respectively.

Esse artigo aborda a relação entre pobreza e (in) segurança alimentar, explicitando os esforços dos vários governos, a partir do estado novo no Brasil, para implantar políticas públicas de combate à pobreza, na perspectiva de valorização da qualidade de vida da população. Os estudos do médico Josué de Castro (2019), subsidiaram essas políticas, apontando a fome não apenas como falta de alimento no organismo, mas como algo mais complexo, que envolve a ausência da saúde e a precocidade da morte, sobretudo em crianças e idosos. O SISTEMINHA EMBRAPA UFU FAPEMIG ? Sistema Integrado de Produção de Alimentos, aqui descrito como experiência exitosa, destina-se a famílias que têm pouca terra e quase nenhum recurso financeiro, é executado em sistema modular com revezamento semanal de plantios, trazendo como consequência a seguridade alimentar da família, bem como, a geração de excedente para comercialização.

Loss in the supply chain of small ruminants owing to condemnations of carcasses in the abattoirs and slaughterhouses is common in northeastern Brazil. This study aims to identify bacterial agents, including Mycobacterium spp., in the abscesses found in the postmortem analysis of the carcasses of sheep and goats bred in northeastern Brazil. Our analysis involved 679 goats and 1,838 sheep carcasses. Abscess samples were extracted and inoculated on blood agar and Lowenstein Jensen with pyruvate or glycerol for bacterial isolation. We then performed polymerase chain reaction of the hps 65 gene; samples positive for Mycobacterium spp. were subjected to DNA sequencing. Relative frequencies of abscesses in goats and sheep were 5.44 and 3.26%, respectively. Microbiological analysis revealed 87.7% bacterial growth in the inoculated samples. Among these, Corynebacterium pseudotuberculosisrepresented 67.7% of the isolates. We observed 1.9% mycobacteria growth in the abscess samples inoculated on Lowenstein-Jensen medium. PCR of DNA extracted from abscesses samples showed amplification of 0.9% of samples. After sequencing, Mycobacterium spp. isolate was identified as M. novocastrense. C. pseudotuberculosis was the main agent responsible for the formation of abscesses in the examined animals, and we did not identify any species of the M. tuberculosis complex in the examined small ruminants.

As doenças cardiovasculares representam um grande problema de saúde pública e alimentos contendo polifenois, como uvas e vinhos, podem desencadear benefícios ao sistema cardiovascular. Neste trabalho objetivou-se avaliar as características físico-químicas e o efeito vasorelaxante de Vinhos Tintos do Vale do São Francisco (VTVSF), safra 2010: Duccos (uva Petit verdot), Terranova (uva Shiraz) e Rio Sol (uva Cabernet Sauvignon/Shiraz 50% de cada). Foram avaliados os seguintes parâmetros: pH, Extrato Seco(ES), Fenólicos Totais (FT) e Antocianinas Totais(AT). Resultados: Duccos (pH: 3,81 ± 0,00; ES:41,03 g/L ± 0,14; FT(280 nm): 83,13 ± 0,14; AT: 171,21mg/L ± 0,58);Terranova (pH: 3,69 ± 0,00; ES:34,17 g/L ± 0,17; FT(280 nm): 104,87 ± 0,17; AT: 78,33 mg/L ±0,17) e oRio Sol (pH: 3,71 ± 0,00; ES:32,00 g/L ± 0,03; FT(280 nm): 82,57 ± 0,17; AT: 78,33 mg/L ± 0,17). Para avaliação do efeito vasorelaxante, utilizou-se anéis de artéria mesentérica superior isolada de rato(n=6). Demonstrando-se que o efeito vasorelaxante é predominantemente dependente da presença de endotélio vascular, com valores de vasorrelaxamento expressos como efeito máximo (Emáx): Duccos (104,63 ± 7,45%), Terranova (80,74 ± 6,85%) e Rio Sol (100,31 ± 4,70%). O vinho Duccos apresentou maior potencial relaxante desencadeado pela ativação da via NO-GMPc-PKG e maior quantidade de: ES, FT e AT, o que sugere que dentre os vinhos analisados é o que pode desencadear o melhor benefício cardiovascular. Palavras chaves:Vinho; polifenois;vasodilatação;óxido nítrico. Cardiovascular diseases represent a greater public health problem and foods containing polyphenols, such as grapes and wine, can trigger benefits to the cardiovascular system. The following study aimed to evaluate the physico chemical characteristics and the vasorelaxant effect of red wines from São Francisco Valley (RWVSF), 2010 harvest:Duccos (Petit verdot grape), Terranova (Shiraz grape)e Rio Sol (grape Cabernet Sauvignon/Shiraz 50% of each). The following parameters were valuated: pH, dry extract (DE), total phenolics (TP) and total anthocyanins (TA).Results: Duccos (pH: 3.81 ± 0.00; DE: 41.03 g/L ± 0.14; TP (280 nm): 83.13 ± 0.14; TA: 171.21 mg/L ± 0.58); Terranova (pH: 3.69 ± 0.00; DE: 34.17 g/L ± 0.17;TP (280 nm): 104.87 ± 0.17; TA: 78.33 mg/L ± 0.17) e o Rio Sol (pH: 3.71 ± 0.00;DE: 32.00 g/L ± 0.03; TP (280 nm): 82.57 ± 0.17; TA: 78.33 mg/L ± 0.17).In order to evaluate the vasorelax anteffect, superior mesenteric artery rings isolated from rats (n=6)were used.It demonstrated that the vasorelaxant effect is predominantly dependent on the presence of vascular endothelium, with values expressed as maximum effect (Emax). Duccos (104.63 ± 7.45%), Terranova (80.74 ± 6.85%) and Rio Sol (100.31 ± 4. 70%). The Duccos wine showed the highest relaxing potential, which was triggered by the activation of NO-GMPc-PKG pathway and a greater amount of: DE, TP and AT, which suggests that one of the wines reviewed,is what may trigger a better cardiovascular benefit.

Objetivou-se avaliar o efeito das variáveis meteorológicas e das dietas com diferentes níveis de feno de erva sal (Atriplex nummularia Lindl.) e palma forrageira (Opuntia fícus indica Mill) sobre as respostas horárias dos parâmetros fisiológicos e comportamento ingestivo dos novilhos da raça Sindi. Foram utilizados oito animais da raça Sindi, distribuídos em quadrado latino duplo com quatro tratamentos: 15, 30, 45 e 60% de inclusão de feno de erva-sal, em quatro períodos. As variáveis meteorológicas ao longo do dia exerceram forte influência sobre todas as respostas fisiológicas dos animais. Entretanto, a distribuição das atividades do comportamento ingestivo (alimentação, ruminação e ócio), ao longo das 24 horas, foi ritmada pelos horários de distribuição do alimento, mostrando-se pouco influenciada pelas variáveis meteorológicas. O consumo das dietas experimentais, contendo os menores percentuais de feno de erva-sal pelos novilhos da raça Sindi, proporcionaram aumento na frequência respiratória dos animais, sem, no entanto, alterar a temperatura retal.

OBJETIVO: avaliar a associação entre a exposição dos genitores aos agrotóxicos e nascimentos com defeitos congênitos no Vale do São Francisco, bem como o perfil sociodemográfico e os defeitos encontrados. MÉTODOS: estudo tipo caso-controle, sendo que para cada caso (recém-nascido com defeito congênito), eram dois controles (recém-nascidos saudáveis) nascidos na cidade de Petrolina, no Vale do São Francisco, em 2009. A amostra constou de 42 casos e 84 controles. Os dados formam colhidos com uso de questionário estruturado, adaptado do Estudo Colaborativo Latino-Americano de Malformações Congênitas (ECLAMC), acrescido de questões relacionadas à exposição aos agrotóxicos, análise do prontuário e contato com a pediatra do hospital. Foi realizado o teste do χ2 com nível de significância de 5% para identificar as variáveis com maiores diferenças entre os grupos caso e controle. Em seguida, foi calculado o Odds Ratio (OR) amostral, bem como o OR obtido por análise de regressão logística e, finalmente, realizou-se uma análise de regressão logística multivariada. RESULTADOS: houve maior exposição aos agrotóxicos durante a gestação em neonatos com defeitos congênitos se comparados aos saudáveis. Maior risco foi observado quando pelo menos um dos genitores foi exposto aos agrotóxicos (OR ajustado = 1,3; IC95% = 0,4-3,9). As variáveis sociodemográficas associadas aos defeitos congênitos foram: baixa escolaridade, baixo peso, prematuridade, genitores jovens, doenças crônicas e fatores físicos. Foram encontrados com maior frequência os polimalformados e os defeitos dos sistemas musculoesquelético e nervoso. CONCLUSÃO: o presente estudo, a despeito de não apresentar significância, sugere associação entre a exposição aos agrotóxicos e a ocorrência de defeitos congênitos. PURPOSE: to evaluate associations between parental exposure to pesticides and births with congenital defects in São Francisco Valley, as well as the demographic profile and the defects found. METHODS: in this case-control study, each case (newborns with congenital defects) had two controls (healthy newborns). The subjects were born in the city of Petrolina, in São Francisco Valley, in 2009. The sample consisted of 42 cases and 84 controls. Data were gathered by a structured questionnaire adapted from Latin-American Collaborative Study of Congenital Malformations (ECLAMC), with the addition of questions related to exposure to pesticides, analysis of the medical records and contact with the hospital's pediatrician. The χ2 test was performed with a significance level of 5% to identify the variables with the greatest differences between case and control groups. Odds Ratio (OR) for the sample was calculated, as well as the OR obtained by logistic regression analysis, and finally, multivariate logistic regression analysis was performed. RESULTS: there was a greater exposure to pesticides during pregnancy in infants with congenital defects compared to healthy subjects. Increased risk was observed when at least one parent was exposed to pesticides (adjusted OR = 1.3; 95%CI = 0.4 - 3.9). The sociodemographic variables associated with congenital defects were: low school level, low weight, prematurity, young parents, chronic diseases, and physical factors. Multiple malformations and defects of the musculoskeletal and nervous systems were more frequently found. CONCLUSIONS: the present study suggests an association between exposure to pesticides and the occurrence of congenital defects, although the data were not significant.

Para mensurar a qualidade física foram avaliados atributos nas camadas de 0,0-0,10; 0,10-0,20; 0,20-0,30; 0,30-0,40 m em Latossolo Vermelho acriférrico, muito argiloso. O delineamento experimental foi inteiramente casualizado com quatro sistemas de uso (milho, cana-de-açúcar, pastagem e cerrado nativo), quatro profundidades e quatro repetições. Foram avaliadas as propriedades a seguir: composição granulométrica, grau de floculação das argilas, densidade e porosidade do solo, retenção de água e o parâmetro “S. Os sistemas de uso e manejo causaram degradação física do solo, destacando-se o sistema de uso com pastagem e pastejo intensivo com menor qualidade física do solo para o desenvolvimento das plantas. A qualidade física do solo, avaliada por meio dos atributos físicos, seguiu a seguinte ordem: cerrado > milho > cana-de-açúcar > pastagem. O Latossolo Vermelho acriférrico, apesar de apresentar excelente estrutura física, necessita de um manejo adequado para evitar a compactação excessiva. The soil physical quality is defined as the soil capacity to maintain the sustainable productivity during the years. To assess soil physical quality, attributes were evaluated in the layers of 0.0-0.10, 0.10-0.20, 0.20-0.30, 0.30-0.40 m in acrustox. The experimental design was entirely randomized, with four systems of use ( corn, sugar-cane, pasture and native vegetation), four soil depths and four replications. The parameter evaluated were: texture, degree of clay flocculation, soil bulk density, porosity, water retention and "S" parameter. The usage and management systems caused soil physical degradation, being greater in pasture system with intensive usage, with smaller soil physical quality for plants development. The soil physical quality, evaluated by physical attributes, followed the following order: native vegetation > maize > sugar-cane > pasture. The Oxisol, although shows present excellent physical structure and needs an adequate management to prevent excessive compaction.

Nesse artigo, buscaremos refletir sobre os trânsitos dos bens arqueológicos nas paisagens do presente. Nosso interesse com a empreitada será o de explicitar algumas formas de trabalho com esses materiais, olhando atentamente para os seus usos e intepretações nem sempre autorizados. Desse modo, trazemos para discussão alguns contextos do município de São Braz do Piauí, situado no Corredor Ecológico que separa os parques nacionais Serra da Capivara e Serra das Confusões. No local, são frequentes os achados de cerâmicas e líticos, principalmente urnas funerárias, efetuados pela população em suas residências e vias públicas. Por meio de uma arqueologia pública do presente, procuramos acompanhar as narrativas produzidas sobre esses engajamentos, admitindo as possibilidades de se relacionarem com a operacionalização de outras arqueologias. Abstract: In this article, we will seek to reflect on the transit of archaeological objects in the social landscapes of the present. Our interest in the project will be to highlight some ways of working with these materials, looking carefully at their uses and interpretations that are not always authorized. Thus, we bring to discussion some contexts of the city of São Braz do Piauí, located in the Corredor Ecológico that separates the national parks Serra da Capivara and Serra das Confusões. On the scene, the findings of ceramics and lithics are frequent, mainly funerary pottery, made by the population in their homes and public roads. Through a public archeology of the present, we seek to follow the narratives produced about these engagements, admitting the possibilities of relating to the operationalization of other archeologies.

Background: Active videogames (AVGs) have been primarily studied in healthy individuals. To use the technology in type 1 diabetes mellitus (T1DM) patients, cardiovascular and enjoyment responses should be studied and compared with traditional exercises. Objective: To compare the effects of AVG and running exercises on cardiovascular and enjoyment responses in T1DM patients. Methods: Cardiovascular (heart rate, HR; blood pressure, BP; double product, DP; vessel diameter, VD; % endothelial function, %EF) and enjoyment levels were recorded during 3 weeks and twice per week. On the first day, patients completed baseline assessments, familiarization, and a 30-minute control session. On the second day and after 24 hours, the measurements were repeated. Patients repeated the same protocol in the second and third weeks and performed randomized active sessions. Results: T1DM patients had similar cardiovascular responses during active exercises without significant postexercise hypotension to HR, BP, and DP over time. However, VD and %EF values were higher in AVG, followed by running and rest, 30 minutes and after 24 hours (VD-AVG: 39.6 – 9.5, 48.8 – 12.3 and 56.6 – 13.9 mm; VD-running: 41.5 – 9.9, 47.4 – 10.1 and 46.4 – 12.4 mm; %EF-AVG: 9.6 – 8.5, 29.6 – 17.1 and 45.4 – 25.9%; %EF-running: 7.3 – 9.4, 14.8 – 14.1 and 26.8 – 18.9%, p < 0.05). Enjoyment was also higher in AVG compared with the running session (9.4 – 0.7 vs. 7.7 – 1.6; p < 0.05). Conclusions: AVG presented similar cardiovascular responses to running with higher endothelial and enjoyment levels.

While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests. Resumen: Los bosques tropicales son los ecosistemas más diversos y productivos del mundo y entender su funcionamiento es crítico para nuestro futuro colectivo. Sin embargo, hasta hace muy poco, los esfuerzos para medirlos y monitorearlos han estado muy desconectados. El trabajo en redes es esencial para descubrir las respuestas a preguntas que trascienden las fronteras y los plazos de las agencias de financiamiento. Aquí mostramos cómo una comunidad global está respondiendo a los desafíos de la investigación en ecosistemas tropicales a través de diversos equipos realizando mediciones árbol por árbol en miles de parcelas permanentes de largo plazo. Revisamos los descubrimientos más importantes de este trabajo y discutimos cómo este proceso está cambiando la ciencia relacionada a los bosques tropicales. El enfoque central de nuestro esfuerzo implica la conexión de iniciativas locales de largo plazo con protocolos estandarizados y manejo de datos para producir resultados que se puedan trasladar a múltiples escalas. Conectando investigadores tropicales, elevando su posición y estatus, nuestro modelo de Red Social de Investigación reconoce el rol fundamental que tienen, para el descubrimiento científico, quienes generan o producen los datos. Concebida en 1999 con RAINFOR (Suramérica), nuestras redes de parcelas permanentes han sido adaptadas en África (AfriTRON) y el sureste asiático (T-FORCES) y ampliamente replicadas en el mundo. Actualmente todas estas iniciativas están integradas a través de la ciber-infraestructura de ForestPlots.net, conectando colegas de 54 países en 24 redes diferentes de parcelas. Colectivamente, estas redes están transformando nuestro conocimiento sobre los bosques tropicales y el rol de éstos en la biósfera. Juntos hemos descubierto cómo, dónde y porqué el carbono y la biodiversidad de los bosques tropicales está respondiendo al cambio climático y cómo se retroalimentan. Esta colaboración pan-tropical de largo plazo ha expuesto un gran sumidero de carbono y sus tendencias, mostrando claramente cuáles son los factores más importantes, qué procesos se ven afectados, dónde ocurren los cambios, los tiempos de reacción y las probables respuestas futuras mientras el clima continúa cambiando. Apalancando lo que realmente es una tecnología antigua, las redes de parcelas están generando una verdadera y moderna revolución en la ciencia tropical. En el futuro, la humanidad puede beneficiarse enormemente si se nutren y cultivan comunidades de investigadores de base, actualmente con la capacidad de generar información única y de largo plazo para entender los que probablemente son los bosques más preciados de la tierra. Resumo: Florestas tropicais são os ecossistemas mais diversos e produtivos da Terra. Embora uma boa compreensão destas florestas seja crucial para o nosso futuro coletivo, até muito recentemente os esforços de medições e monitoramento foram amplamente desconexos. É essencial formarmos redes para obtermos respostas que transcendem fronteiras e horizontes de agências financiadoras. Neste estudo nós mostramos como uma comunidade global está respondendo aos desafios da pesquisa de ecossistemas tropicais, com equipes diversas medindo florestas, árvore por árvore, em milhares de parcelas monitoradas à longo prazo. Nós revisamos as maiores descobertas científicas deste trabalho, e mostramos também como este processo está mudando a ciência de florestas tropicais. Nossa abordagem principal envolve unir iniciativas de base a protocolos padronizados e gerenciamento de dados a fim de gerar resultados robustos em escalas ampliadas. Ao conectar pesquisadores tropicais e elevar seus status, nosso modelo de Rede de Pesquisa Social reconhece o papel-chave do produtor dos dados na descoberta científica. Concebida em 1999 com o RAINFOR (América do Sul), nossa rede de parcelas permanentes foi adaptada para África (AfriTRON) e Sudeste asiático (T-FORCES), e tem sido extensamente reproduzida em todo o mundo. Agora estas múltiplas iniciativas estão integradas através de uma infraestrutura cibernética do ForestPlots.net, conectando colegas de 54 países de 24 redes de parcelas. Estas iniciativas estão transformando coletivamente o entendimento das florestas tropicais e seus papéis na biosfera. Juntos nós descobrimos como, onde e por que o carbono e a biodiversidade da floresta estão respondendo às mudanças climáticas, e seus efeitos de retroalimentação. Esta duradoura colaboração pantropical revelou um grande sumidouro de carbono persistente e suas tendências, assim como tem evidenciado quais direcionadores são mais importantes, quais processos florestais são mais afetados, onde eles estão mudando, seus atrasos no tempo de resposta, e as prováveis respostas das florestas tropicais conforme o clima continua a mudar. Dessa forma, aproveitando uma notável tecnologia antiga, redes de parcelas acendem faíscas de uma moderna revolução na ciência das florestas tropicais. No futuro a humanidade pode se beneficiar incentivando estas comunidades basais que agora são coletivamente capazes de gerar conhecimentos únicos e duradouros sobre as florestas mais preciosas da Terra. Résume: Les forêts tropicales sont les écosystèmes les plus diversifiés et les plus productifs de la planète. Si une meilleure compréhension de ces forêts est essentielle pour notre avenir collectif, jusqu'à tout récemment, les efforts déployés pour les mesurer et les surveiller ont été largement déconnectés. La mise en réseau est essentielle pour découvrir les réponses à des questions qui dépassent les frontières et les horizons des organismes de financement. Nous montrons ici comment une communauté mondiale relève les défis de la recherche sur les écosystèmes tropicaux avec diverses équipes qui mesurent les forêts arbre après arbre dans de milliers de parcelles permanentes. Nous passons en revue les principales découvertes scientifiques de ces travaux et montrons comment ce processus modifie la science des forêts tropicales. Notre approche principale consiste à relier les initiatives de base à long terme à des protocoles standardisés et une gestion de données afin de générer des résultats solides à grande échelle. En reliant les chercheurs tropicaux et en élevant leur statut, notre modèle de réseau de recherche sociale reconnaît le rôle clé de l'auteur des données dans la découverte scientifique. Conçus en 1999 avec RAINFOR (Amérique du Sud), nos réseaux de parcelles permanentes ont été adaptés à l'Afrique (AfriTRON) et à l'Asie du Sud-Est (T-FORCES) et largement imités dans le monde entier. Ces multiples initiatives sont désormais intégrées via l'infrastructure ForestPlots.net, qui relie des collègues de 54 pays à travers 24 réseaux de parcelles. Ensemble, elles transforment la compréhension des forêts tropicales et de leur rôle biosphérique. Ensemble, nous avons découvert comment, où et pourquoi le carbone forestier et la biodiversité réagissent au changement climatique, et comment ils y réagissent. Cette collaboration pan-tropicale à long terme a révélé un important puits de carbone à long terme et ses tendances, tout en mettant en évidence les facteurs les plus importants, les processus forestiers qui sont affectés, les endroits où ils changent, les décalages et les réactions futures probables des forêts tropicales à mesure que le climat continue de changer. En tirant parti d'une technologie remarquablement ancienne, les réseaux de parcelles déclenchent une révolution très moderne dans la science des forêts tropicales. À l'avenir, l'humanité pourra grandement bénéficier du soutien des communautés de base qui sont maintenant collectivement capables de générer une compréhension unique et à long terme des forêts les plus précieuses de la Terre. Abstrak: Hutan tropika adalah di antara ekosistem yang paling produktif dan mempunyai kepelbagaian biodiversiti yang tinggi di seluruh dunia. Walaupun pemahaman mengenai hutan tropika amat penting untuk masa depan kita, usaha-usaha untuk mengkaji dan mengawas hutah-hutan tersebut baru sekarang menjadi lebih diperhubungkan. Perangkaian adalah sangat penting untuk mencari jawapan kepada soalan-soalan yang menjangkaui sempadan dan batasan agensi pendanaan. Di sini kami menunjukkan bagaimana sebuah komuniti global bertindak balas terhadap cabaran penyelidikan ekosistem tropika melalui penglibatan pelbagai kumpulan yang mengukur hutan secara pokok demi pokok dalam beribu-ribu plot jangka panjang. Kami meninjau semula penemuan saintifik utama daripada kerja ini dan menunjukkan bagaimana proses ini sedang mengubah bidang sains hutan tropika. Teras pendekatan kami memberi tumpuan terhadap penghubungan inisiatif akar umbi jangka panjang dengan protokol standar serta pengurusan data untuk mendapatkan hasil skala besar yang kukuh. Dengan menghubungkan penyelidik-penyelidik tropika dan meningkatkan status mereka, model Rangkaian Penyelidikan Sosial kami mengiktiraf kepentingan peranan pengasas data dalam penemuan saintifik. Bermula dengan pengasasan RAINFOR (Amerika Selatan) pada tahun 1999, rangkaian-rangkaian plot kekal kami kemudian disesuaikan untuk Afrika (AfriTRON) dan Asia Tenggara (T-FORCES) dan selanjutnya telah banyak dicontohi di seluruh dunia. Kini, inisiatif-inisiatif tersebut disepadukan melalui infrastruktur siber ForestPlots.net yang menghubungkan rakan sekerja dari 54 negara di 24 buah rangkaian plot. Secara kolektif, rangkaian ini sedang mengubah pemahaman tentang hutan tropika dan peranannya dalam biosfera. Kami telah bekerjasama untuk menemukan bagaimana, di mana dan mengapa karbon serta biodiversiti hutan bertindak balas terhadap perubahan iklim dan juga bagaimana mereka saling bermaklum balas. Kolaborasi pan-tropika jangka panjang ini telah mendedahkan sebuah sinki karbon jangka panjang serta arah alirannya dan juga menjelaskan pemandu-pemandu perubahan yang terpenting, di mana dan bagaimana proses hutan terjejas, masa susul yang ada dan kemungkinan tindakbalas hutan tropika pada perubahan iklim secara berterusan di masa depan. Dengan memanfaatkan pendekatan lama, rangkaian plot sedang menyalakan revolusi yang amat moden dalam sains hutan tropika. Pada masa akan datang, manusia sejagat akan banyak mendapat manfaat jika memupuk komuniti-komuniti akar umbi yang kini berkemampuan secara kolektif menghasilkan pemahaman unik dan jangka panjang mengenai hutan-hutan yang paling berharga di dunia.

Thus, from the geomorphological mapping, the morphodynamic processes that characterize the relief compartments are pointed out and important aspects to proper planning of these terrains. The study area covers the municipalities of the Costa das Baleias Region (south coast of Bahia State), geomorphologically marked by Coastal Tablelands. The lack of studies on this scenario, very frequent on the Brazilian coast, justified our choice, in order to contribute effectively to the study of these environments. The geomorphological map was prepared based on aerial photographs with a scale of 1: 25,000 and field data. The results showed the concentration of erosional forms on the exposed slopes to the east/southeast tablelands. In addition to the trays, there are alluvial terraces and quaternary coastal plains that demonstrate morphologies still in the sedimentation phase, a fact that determines limitations for use due to the instability of the terrain and the occurrence of periodic flooding. Thus, this work intends to subsidize planning proposals for the land use and occupation of Coastal Tablelands. Colegiado de Geografia Universidade Federal do Vale do São Francisco - UNIVASF.

In this way, propolis is an alternative in the treatment of diseases because it has antimicrobial activity, mainly because of the presence of flavonoids in its composition. The aim of this study was to evaluate the antimicrobial potential of propolis to Staphylococcus spp. Isolated from cases of goat mastitis and qualify the crude ethanoic extract by high performance liquid chromatography (HPLC). In this study, the minimum bactericidal concentration values of propolis extracts in ethanol, ethyl acetate and hexane showed that the best concentrations capable of promoting the highest mortality of the isolates of Staphylococcus spp. from mastitis in goats, were 6250, 3125 and 1562.5μg/mL, respectively. By the microplate adherence test, it was found that 20.78% isolates were not able to form biofilm, 14.70% were classified as moderate and 64.70% were weak and none as a strong biofilm producer. Propolis in its different diluents was able to affect the formation of biofilm and showed a pronounced marked antimicrobial activity against Staphylococcus spp. strains and may be indicated for use in in vivo studies.

The analysis of the 616 sheep serum samples revealed animal-level seroprevalence of T. gondii in the order of 52.4 % and of N. caninum of 60.6 %. Prevalence of co-infections was 33.4 %. The herd-level seroprevalence was 100 % for both the parasites. Applying of multivariate logistic regression analysis, test of the association between seroprevalence of T. gondii infection and the potential predictors showed that feed, fetal malformation, abortion, neurological problems (lambs), presence of rodents were the significant (P < 0.05) predictors. The variables presence of rodents, cats, wild animals and main activity showed statistical association (P < 0.05) with the seroprevalence of N. caninum. Due to the high prevalence of T. gondii and N. caninum found in this study, the absence of specific slaughterhouses for sheep and raw or undercooked sheep meat for human consumption we concluded that sheep can represent an important source of infection for humans.

International audience; Background: GATA factors, which constitute a family of transcription regulatory proteins, participate in gastrointestinal development. Trefoil factor 1 (TFF1) plays a crucial role in mucosal defense and healing, and evidence suggests that GATA-5 mediated its regulation. Gastric cancer is a multiple-step process triggered by Helicobacter pylori and is characterized by accumulation of molecular and epigenetic alteration. The aim of this study was to evaluate the effect of H. pylori infection on the regulation of GATA-5 and TFF1 in vitro and in vivo.Results: Infected cells exhibited upregulation of GATA-5 and TFF1 after 48 h. An increase in GATA-5 and TFF1 mRNA levels was also found in mice samples after 6 and 12 months of infection, respectively. In human samples, we found an association between H. pylori infection and GATA-5 upregulation. In fact, among H. pylori-infected patients, hypermethylation was observed in 45.5% of pediatric samples, in 62.6% of chronic gastritis samples, and in 63% of gastric cancer samples. Regarding TFF1, the expression levels were similar in pediatrics and adults patients, and were independent of H. pylori infection, and the expression of these factors was downregulated in gastric cancer samples. GATA-5 promoter methylation was associated with a decrease in TFF1 mRNA levels.Conclusions: Our results suggest that the upregulation of GATA-5 and TFF1 observed in vitro and in vivo may be correlated with a protective effect of the mucosa in response to infection. The epigenetic inactivation of GATA-5 observed in human biopsies from infected patients may suggest that this alteration is an early event occurring in association with H. pylori infection.

Despite being a priority region for biodiversity conservation, the role of protected and unprotected forest remnants for long-term species conservation is unknown. Here, we unveil the main patterns of occurrence and distribution of medium- and large-sized mammals in remnants of the Atlantic Forest of Southern Bahia, to generate subsidies for applied conservation strategies. We recorded mammals using camera-traps, active search, and/or line-transect surveys and complemented our species list with literature data. We thus obtained information on richness attributes, relative abundance, and biomass of mammal species per forest remnant, compared assemblages in protected and unprotected areas, and finally investigated both species-area and biomass-area relationships. From 72 forest remnants assessed, we recorded 45 mammal species, including 19 threatened locally. Protected areas were richer in species, especially concerning threatened ones, and concentrated most of the mammal biomass, which presented consistently low values for most areas. The positive and significant species-area and biomass-area relationships further corroborate these patterns since protected areas are larger in size. Despite the historic anthropogenic pressures, we conclude that Southern Bahia still harbors an expressive mammal diversity, with protected areas being critical to maintain most of the species' richness and biomass across the entire region. Nevertheless, small unprotected remnants (

Arbuscular mycorrhizal fungi (AMF) play a key role in the maintenance of the balance of terrestrial ecosystems, but little is known about the biogeography of these fungi, especially on tropical islands. This study aims to compare AMF community structure along a transect crossing a fluvial-marine island and relate these communities with soil and vegetation parameters to shed light on the forces driving AMF community structure on a local scale. We tested the hypothesis that the composition of AMF communities changes across the island, even within short distances among sites, in response to differences in edaphic characteristics and vegetation physiognomies. We sampled roots and soils in five different natural and degraded habitats: preserved mangrove forest (MF), degraded mangrove forest (MD), natural Restinga forest (RF), and two regeneration Restinga forests (RR1 and RR2) on Ilha da Restinga, northeastern Brazil. We determined the mycorrhizal colonization rate and AMF community structure based on morphological spore identification. The island soils were sandy with pH varying from acid to neutral; higher levels of organic matter were registered in RF and lower in MF; other chemical and physical soil attributes differed along the habitat types on the island. In total, 22 AMF species were identified, without any difference in species richness. However, the diversity and composition of AMF communities, spore abundance per families, and mycorrhizal colonization were statistically different among the habitats. The composition of AMF communities was strongly related to soil characteristics, especially the sum of exchangeable bases. Our results indicate that the different habitat types have diverse AMF communities even within short distances among habitats. In conclusion, islands with high spatial heterogeneity in soil parameters and diverse vegetation are potential refuges for the diversity conservation of AM fungi.

La préhistoire américaine dans son ensemble est actuellement celle qui est la plus controversée mais aussi, d’une certaine façon, la plus en mouvement(s) avec les débats d’idées sur la question des premiers peuplements. D’un côté, il y a les partisans d’une chronologie courte, qui varie selon les découvertes entre 13,000 ans et 15,000 ans, et de l’autre, il y a les partisans d’une occupation bien plus ancienne, portés par leurs données qui les conduisent à accepter l’évidence des faits et non celles des seules interprétations. La synthèse qui suit est l’aboutissement de dix années de recherche systématique française dans la région du Piauí, Brésil, d’accumulation de données, de datations et d’analyses. Outre leurs richesses, en quantité, qualité, exceptionnalité, leur originalité d’approche transdisciplinaire, ou encore les premières conclusions auxquelles elles aboutissent qui bousculent l’histoire mondiale des migrations et peuplements, nos recherches permettent de faire briller la rigueur de l’enseignement et de la recherche française dans l’ensemble des Amériques. Nous avertissons le rapporteur que ce rapport a été conçu comme une tentative de synthèse plutôt qu’un rapport stricto sensu sur les quatre dernières années. Ce programme est un parcours dont on espère percevoir l’horizon, mais qui s’éloigne un peu plus chaque année au fur et à mesure de la profondeur temporelle de nos découvertes.

This study aimed to evaluate the seroprevalence of anti-Babesia caballi and anti-Theileria equi antibodies based on the detection of these agents in equine blood and in ticks on horses in the municipality of Petrolina, Pernambuco, northeastern Brazil. Blood samples were drawn from 393 horses and sera were examined by ELISA. The presence of tick infestations was evaluated, and 101 ticks were subjected to DNA amplification for the detection of Babesia spp. by polymerase chain reaction (PCR). No parasites were detected in the blood smears. Anti-B. caballi and anti-T. equi antibodies were found in 27.2% (107/393) and 34.8% (137/393) horses, respectively. Infestation by Dermacentor nitens was detected in 4.3% (17/393) of the horses. There was no DNA amplification of the agents in ticks. The risk factors for the presence of anti-T. equi antibodies (P < 0.05) were: Purebred (P < 0.001), animals older than 156 months (P = 0.014), and the presence of ticks (P = 0.001). No risk factors for B. caballi were identified. This study confirmed the circulation of agents of equine piroplasmosis in the municipality of Petrolina, state of Pernambuco, Brazil.

No. of bitstreams: 0 Previous issue date: 2019-02-01 Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

The drug is available in the form of immediaterelease tablets for 100-mg (adult) and 12.5-mg (pediatric) doses. The drug is administered two or three times daily for 60 days. The high frequency of daily administrations and the long period of treatment are factors that significantly contribute to the abandonment of therapy, affecting therapeutic success. Accordingly, this study aimed to evaluate the preclinical pharmacokinetics of BNZ administered as extended-release tablets (200-mg dose) formulated with different types of polymers (hydroxypropyl methylcellulose K4M and K100M), compared to the tablets currently available. The studies were conducted with rabbits, and BNZ quantification was performed in plasma and urine by ultraperformance liquid chromatography methods previously validated. The bioavailability of BNZ was adequate in the administration of extended-release tablets; however, with the administration of the pediatric tablet, the bioavailability was lower than with other tablets, which showed that the clinical use of this formulation should be monitored. The pharmacokinetic parameters demonstrated that the extended-release tablets prolonged drug release from the pharmaceutical matrix and provided an increase in the maintenance of the drug concentration in vivo, which would allow the frequency of administration to be reduced. Thus, a relative bioavailability study in humans will be planned for implementation of a new product for the treatment of Chagas disease.

Déclaré Patrimoine culturel de l’Humanité par l’UNESCO en 1991, le Parc national de la Serra da Capivara a été créé pour préserver plus de 1500 sites archéologiques. Parmi ces sites, plus de 1200 Tocas ou grottes peintes sont datées de la phase de transition Pléistocène/Holocène. De très nombreux autres sites archéologiques de plein air ou en grotte sont aussi attestés. Le plus célèbre d’entre eux est le site du Boqueirão da Pedra Furada. Sa découverte, en 1980, et les fouilles qui s’en suivirent, dirigées successivement par N. Guidon et F. Parenti, ont permis de mettre au jour pour la première fois au Brésil une séquence stratigraphique allant de l’Holocène jusqu’au début du Pléistocène supérieur, datée au delà de 40 000 ans (MIS3). Cette ancienneté, allant à l’encontre du paradigme limitant l’ancienneté de la colonisation des Amériques au-delà de 12000 ans, a provoqué une très forte polémique. Néanmoins, d’autres sites, tant en Amérique du Sud avec les sites de Monte Verde au sud, de Taima Taima au Venezuela, qu’en Amérique du Nord avec les sites de Meadowcroft en Pennsylvanie et de Cactus Hill aux Etats-Unis, tous fouillés à la même époque – années 80- semblaient confirmer cette réalité. Mais, ces faits allaient à l’encontre de la doxa. Inacceptables, ils furent récusés. Il faudra attendre 2005 pour qu’une une nouvelle expertise, menée par les Professeurs E. Boëda et E. Fogaça, amène à la création d’une nouvelle mission archéologique française financée par le Ministère Français des Affaires Etrangères et Européennes et relance la thématique des premiers peuplements américains à partir du potentiel archéologique qu’offre le sud du Piaui. Après deux programmes quadriennaux, dirigés successivement par M. Rasse et E. Boëda, la présence d’une occupation Pléistocène à partir de 40 000 ans est définitivement attestée. Les nouveaux sites de la Vale da Pedra, sítio do Meio, de Tira Peia, de la Pena, de Barra da Jamela da Antonião, Livierac et Coqueiros offrent chacun une séquence stratigraphique avec de nombreux niveaux archéologiques s’échelonnant globalement entre 40 000 et le début de l’Holocène ancien. A ces sites, nous devons rajouter celui de Boqueirão da Pedra Furada, où une nouvelle fouille aux dépens d’un témoin restant a été entreprise par notre équipe. La concentration de sites pléistocènes dans cette micro-région du Piauí est conséquente et indique un processus de peuplement de l’Amérique du Sud bien plus ancien comme l’attesteraient les anciennes données du site de Boqueirão. Quoiqu’il en soit, les recherches actuelles continuent à élargir la base de données pour déterminer l’identité culturelle des groupes humains qui se sont succédés. A savoir, avons-nous affaire à une colonisation ancienne durant le MIS3 et qui se serait développée sur place, ou à desphénomènes de peuplements successifs, témoins de pulsions migratrices multiples durant ce même stade isotopique comme le laissent supposer certaines données ? Autrement dit, après avoir répondu positivement à la question de l’existence de populations pléistocènes, nous orientons nos recherches sur l’analyse du phénomène de peuplement : à la recherche d’identités culturelles, de chemins migratoires et du tempo migratoire.

The possibility of using infrared thermography associated with prediction systems of these physiological variables can help in decision making, allowing greater welfare and productivity of the animals. With this objective, an experiment was carried out with growing pigs submitted to acute and chronic heat stress, working with a thermoneutrality temperature (22° C) and heat stress (34° C). The results were used for the development of a fuzzy model using as input variables: air dry bulb temperature (°C), average surface temperature (°C) and, as output variables: respiratory frequency (movements/minute) and rectal temperature (°C). The method of inference used was the one of Mamdani having been elaborated six rules and the defuzzification technique used was the one of the Center of Gravity. In the obtained results on simulation model when compared with experimental data was evidenced satisfactory efficiency in respiratory frequency determination and the rectal temperature, in which the R2 values calculated were respectively 0.997 and 0.951 for acute stress and 0.993 and 0.964 for chronic heat stress.

São plantas sensíveis à falta de umidade no solo, sendo necessário manejo adequado da irrigação. Nesse sentido, objetivou-se avaliar o efeito de diferentes lâminas de irrigação sobre os caracteres fitotécnicos e produtivos de Heliconia psittacorum cultivar Golden Torch cultivadas em vaso. O experimento foi conduzido no período de março a outubro de 2014, em blocos casualizados. Foram utilizados cinco tratamentos correspondentes as diferentes lâminas de irrigação [50 (L50), 75 (L75), 100 (L100), 125 (L125) e 150% (L150) da evaporação de água do tanque Classe A (ECA)] com quatro repetições e duas plantas por repetição. Foram realizadas as seguintes avaliações: número de dias para emissão do primeiro perfilho, número de dias para emissão da primeira inflorescência, número de dias para a colheita da inflorescência, ciclo da planta, diâmetro da haste floral, comprimento da haste floral, comprimento da inflorescência, altura de planta, número de perfilhos e produtividade de hastes florais. Foram realizadas leituras de clorofila e medições de área foliar. As lâminas de irrigação testadas influenciaram significativamente o número de dias para colheita da primeira inflorescência, comprimento da haste floral e comprimento da inflorescência. A lâmina de irrigação de 150% da ECA proporcionou melhores resultados para o comprimento da haste floral, comprimento da inflorescência e para área foliar, mas sem diferir das lâminas de 75%, 100% e 125% da ECA. Assim, para o cultivo da helicônia cv. Golden Torch em vaso recomenda-se as lâminas correspondentes de 75% a 150% da ECA. ABSTRACT The genus Heliconia is commercially detached by the exotic appearance of the inflorescences but is susceptible to lack of moisture in the soil, being necessary the irrigation management. In this sense, the objective was to evaluate the effect of different irrigation levels on the plant growth and productive characters of Heliconia psittacorum cv. Golden Torch cultivated in vase. The experiment was conducted from March to October 2014, in a randomized blocks design. Five treatments corresponding to the different irrigation levels were used [50, 75, 100, 125 and 150% of the evaporation measured in Class A (ECA)] with four replicates and two plants per replicate. The following evaluations were carried out: number of days for the emergence of the first tiller, number of days for the emergence of the first inflorescence, number of days for the inflorescence harvest, crop cycle, diameter of the flower stem, length of the flower stem, inflorescence length, plant high, number of tillers and productivity of flower stems. Chlorophyll and leaf area measurements were performed. The irrigation levels tested significantly influenced the number of days for the first inflorescence harvest, length of the flower stem and inflorescence length. The irrigation level of 150% ECA provided better results for the length of the flower stem, inflorescence length and for leaf area but without differences from 75%, 100% and 125% ECA. Thus, for the cultivation of the heliconia cv. Golden Torch in pot can be recommended the level corresponding from 75% to 150% ECA.

Probiotics have been adopted to treat and prevent various diseases in humans and animals. They were notably shown to be a promising alternative to prevent mastitis in dairy cattle. This inflammation of the mammary gland is generally of infectious origin and generates extensive economic losses worldwide. In a previous study, we found that Lactobacillus casei BL23 was able to inhibit the internalisation of Staphylococcus aureus, one of the major pathogens involved in mastitis, into bovine mammary epithelial cells (bMEC). In this study, we further explored the capacity of this strain to modulate the innate immune response of bovine mammary epithelial cells during S. aureus infection. L. casei BL23 was able to decrease the expression of several pro-inflammatory cytokines, including interleukins 6, 8, 1α and 1β and tumour necrosis factor alpha, in S. aureus-stimulated bMEC, 8 h post-infection. On the other hand, L. casei did not impair the induction of defensins, such as lingual antimicrobial peptide and defensin β1 in the presence of S. aureus, and even slightly increased the induction of tracheal antimicrobial peptide during S. aureus infection. Finally, this strain did not alter the expression of the pattern recognition receptor nucleotide-binding oligomerisation domain proteins (NOD2). This study demonstrates that L. casei BL23 displayed anti-inflammatory properties on S. aureus-stimulated bMEC. These results open the way to further characterisation of the BL23 probiotic potential in a bovine mammary gland context and to a better understanding of how all these beneficial properties combine in vivo to combat mastitis pathogens.

The purpose of this study was to evaluate the effects of organic farming of wine grapes under physical and chemical characteristics of Ultisol Brazil's northeastern semiarid region. The samples of soil were collected from the row and interrow of the farming and from the fallow area, at the depths of 0.0-0.10, 0.10-0.20, 0.20-0.30 and 0.30-0.60 m. The samples were collected at six and twelve months after the culture implementation to evaluate the state of aggregation, bulk density and total soil porosity, flocculation index and organic matter contents, calcium, magnesium, and sodium. The results were submitted to statistical analysis. The adoption of organic farming contributed to the soil aggregation process. The bulk density and total soil porosity did not differ significantly between the evaluations, but were within the critical limits for sandy soils. The index flocculation did not have a great influence on the aggregates formation, being this process influenced by organic matter. The period of one year was considered short to obtain conclusive results in improving the soil quality by organic farming, since there are difficulties in tropical soils in promoting significant increases in organic matter content in short time. O objetivo desse trabalho foi avaliar os efeitos do cultivo orgânico de videira de vinho sobre características físicas e químicas de Argissolo da região semiárida do Brasil. Foram coletadas amostras de solo na linha e entrelinha de plantio e em área de pousio nas profundidades de 0,00-0,10, 0,10-0,20, 0,20-0,30 e 0,30-0,60 m. As amostras foram coletadas aos seis e doze meses após a implantação da cultura para avaliação do estado de agregação, densidade do solo, porosidade total, índice de floculação, matéria orgânica, cálcio, magnésio e sódio. Os resultados foram submetido à análise estatística. A adoção do cultivo orgânico contribuiu para o processo de agregação do solo. A densidade do solo e a porosidade total não diferiram significativamente entre as avaliações, entretanto, encontraram-se entre os limites críticos para solos arenosos agricultáveis. A floculação das argilas, não colaborou na formação de agregados, sendo este processo influenciado principalmente pela matéria orgânica. O período de um ano foi considerado curto para obtenção de resultados conclusivos sobre a melhoria da qualidade do solo sob cultivo orgânico, tendo em vista a dificuldade de incremento de matéria orgânica em solos de regiões tropicais.

This study aimed to modeling and bioclimatic zoning of "Saanen" goat milk production in northeastern Brazil. Data were obtained from a 14-year dairy control program for 246 ?Saanen? goat matrices. Dairy production meteorological influence and mathematical modeling were assessed through statistical analyses such as Pearson?s correlation matrix and path analysis. Bioclimatic zoning for current and future scenarios, with climate changes, were delineated using inverse-square distance (ISD) and spherical model (kriging) interpolations. Results showed maximum air temperature to contribute substantially to goat dairy production; therefore, its modeling was based thereon. Current and future dairy production maps highlighted Maranhão and Piauí as regions of limited ?Saanen? milk production. Furthermore, we should emphasize that temperature rises in further scenarios may have significant impact on the potential of dairy farming for the region under study.

The objective of this study was to evaluate the effect of different irrigation levels on flowering, fruit set, carbohydrate and protein content and gas exchange, of apple varietiesin the Brazilian semiarid region. The experimental design was a randomized block with split plots with five replications and four plot irrigation levels (60, 80, 100, and 120% of the reference evapotranspiration (ETo)) and the subplots with two cultivars (Juliet and Princess). As a result, it was found that the number of flowers (NFL), fruits (NFR), shoot percentage (SP) and fruit set (FS) were higher in cv. Juliet. The number of buds (NB) and the fertility index (FI) were higher in cv. Princess. With regard to metabolites, reducing sugar content (RS) had no significant effect among cultivars. The non-reducing sugar content (NRS), total soluble sugar (TSS) and total soluble proteins (TSP) were higher in cv. Princess. As for irrigation depths, TSP, sprouting, flowering and fruit set increased along with the amount of water applied, while the RS, NRS and TSS contents had the opposite behavior.

O adequado manejo de água de irrigação é fundamental para maximização da produção e melhoria da qualidade dos frutos da lima ácida 'Tahiti' no semiárido. O trabalho visou avaliar a influência de diferentes disposições de microaspersores, na produtividade e características físico-químicas dos frutos, nos diferentes quadrantes da planta, num pomar de lima ácida 'Tahiti', com quatro anos, plantada no espaçamento de 5,0 x 7,0 m. O delineamento experimental foi em blocos casualizados, sendo: T1 ? um microaspersor por planta, localizado entre plantas ao longo da fileira; T2 ? um microaspersor para duas plantas, também ao longo da fileira; e T3 ? um microaspersor por planta, localizado a 0,3 m da planta, e seis repetições. Foram consideradas parcelas subdivididas, nas quais se avaliou os frutos nos quadrantes norte, sul, leste e oeste da planta. Os valores de produtividade média apresentaram diferença significativa entre os tratamentos T2 (19.506 kg ha-1) e T1 (13.545 kg ha-1). Os frutos do T3 e T2 apresentaram teor de ácido ascórbico superior aos do T1. Os valores de sólidos solúveis, peso médio de frutos e ácido cítrico apresentaram diferenças significativas entre os quadrantes, demonstrando influência da disposição dos microaspersores sobre os parâmetros físico-químicos dos frutos da lima ácida 'Tahiti', em condições semiáridas de cultivo.

To this effect, we carried out an experiment in a protected environment to evaluate the nutritional status of the chrysanthemum cv. Miramar grown in pots, relative to the electrical conductivity of the nutrient solution and the leaching of salts. The experimental design was of randomized blocks with four replications and the treatments arranged in a 5 × 2 factorial, relating to the levels of electrical conductivity of the nutrient solution (ECs = 2.1; 2.8; 3.5; 4.2 and 4.9 dS m-1) in substrates without (SNL) and with (SWL) washing for the leaching of salts. The nutritional status of the plants was evaluated by leaf analysis of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (Cu, Fe, Mn and Zn). The increase in ECs inhibited the accumulation of micronutrients and of nitrogen, but stimulated the levels of P, K, Ca, Mg and S in the leaf dry mass of the chrysanthemum. The leaching of salts increased the concentration Cu, Fe and Mn in the plant leaves. Among the macronutrients, with the except of calcium and sulphur, no significant difference was observed for N, P, K and Mg relative to the leaching of salts.

MÉTODOS: A amostra foi composta por 1.092 adultos sedentários brasileiros (429 homens e 633 mulheres). Pressão arterial foi acessada e hipertensão arterial diagnosticada. Três fatores de risco cardiovascular foram considerados: obesidade geral (índice de massa corporal), obesidade abdominal (circunferência de cintura) e baixa aptidão cardiorrespiratória (teste submáximo em cicloergômetro). RESULTADOS: A taxa de hipertensão arterial foi de 9,3% (IC95% = 7,6 - 11,2). Houve associação entre mais alta prevalência de hipertensão arterial e diagnóstico de obesidade (p = 0,001), valores elevados de circunferência de cintura (p = 0,001) e baixo VO2máx (p = 0,013). Independentemente de idade e sexo, indivíduos sedentários com simultaneamente baixo consumo máximo de oxigênio e obesidade geral (RP = 5,21 [IC95% = 8,94 - 3,03]; p = 0,001) ou abdominal (RP = 4,05 [IC95% = 2,22 - 7,40]; p = 0,001) apresentaram maior probabilidade de ser hipertenso que os sedentários com nenhum fator de risco. CONCLUSÃO: Adultos sedentários, independentemente de sexo e idade, a presença de baixa aptidão cardiorrespiratória está associada à hipertensão arterial apenas quando também há obesidade geral ou abdominal, indicando que a interação destas variáveis tem relevante peso na gênese da doença. OBJECTIVE: To analyze in a large sample of sedentary adults the possible association between arterial hypertension and decreased physical fitness, and increased general and central obesity. METHODS: The sample was composed by 1,092 (429 male and 663 female) Brazilian sedentary adults. Blood pressure was assessed and arterial hypertension was diagnosed. Three cardiovascular risk factors were considered: general obesity (body mass index), central obesity (waist circumference) and decreased physical fitness (submaximal bicycle ergometer test). RESULTS: Arterial hypertension rate was 9.3% (95% CI = 7.6 - 11.2). There was association between higher occurrence of arterial hypertension and the diagnosis of obesity (p=0.001), elevated values of WC (p = 0.001) and reduced values of VO2max (p = 0.013). Independently of gender and age, sedentary individuals with simultaneous decreased physical fitness plus general (PR=5.21 [95% CI = 8.94-3.03]; p=0.001) and central (PR = 4.05 [95% CI = 2.22-7.40]; p = 0.001) obesity presented higher likelihood to have arterial hypertension than sedentary individuals with none cardiovascular risk factor. CONCLUSION: Sedentary adults, independently of both gender and age, the presence of low cardiorespiratory fitness is associated with increased occurrence of arterial hypertension only when there is either increased central or general adiposity indicating that the interaction of these variables have relevant burden in the genesis of the disease. OBJETIVO: Analizar, en una muestra grande de adultos sedentarios, la posible vinculación entre hipertensión arterial y reducción de aptitud cardiorrespiratoria, con más obesidad general y central. MÉTODOS: La muestra se compuso de 1.092 adultos sedentarios brasileños (429 hombres y 663 mujeres). La presión arterial fue evaluada y la hipertensión arterial fue diagnosticada. Tres factores de riesgo cardiovascular fueron considerados: obesidad general (índice de masa corporal), obesidad central (circunferencia de la cintura) y baja aptitud cardiorrespiratoria (prueba submáxima de ergometría en bicicleta). RESULTADOS: La tasa de hipertensión arterial fue 9,3% (IC95% = 7,6 - 11,2). Hubo asociación entre la prevalencia más alta de hipertensión arterial y el diagnóstico de obesidad (p = 0,001), valores altos de circunferencia de cintura (p = 0,001) y bajo VO2max (p = 0,013). Independientemente de edad y sexo, los individuos sedentarios con, simultáneamente, baja aptitud cardiorrespiratoria, y obesidad general (RP = 5,21 [IC95% = 8,94 - 3,03]; p = 0,001) y central (RP = 4,05 [IC95% = 2,22 - 7,40]; p = 0,001) presentaron más probabilidades de ser hipertensos que los sedentarios con ningún factor de riesgo cardiovascular. CONCLUSIÓN: En adultos sedentarios, sin considerar sexo ni edad, la presencia de baja aptitud cardiorrespiratoria está vinculada a la hipertensión arterial solamente cuando hay adiposidad general o central, indicando que la interacción de estas variables tiene peso relevante en la génesis de la enfermedad.

Currently, there is a lack of information on the prevalence of disease caused by these pathogens, which is partially due to a reduction in the frequency of routine laboratory testing. In this study, a multiplex polymerase chain reaction (mPCR) assay that can simultaneously identify and determine the toxigenicity of these corynebacterial species with zoonotic potential was developed. This assay uses five primer pairs targeting the following genes: rpoB (Corynebacterium spp), 16S rRNA (C. ulcerans and C. pseudotuberculosis), pld (C. pseudotuberculosis), dtxR (C. diphtheriae) and tox [diphtheria toxin (DT) ]. In addition to describing this assay, we review the literature regarding the diseases caused by these pathogens. of the 213 coryneform strains tested, the mPCR results for all toxigenic and non-toxigenic strains of C . diphtheriae, C. ulcerans and C. pseudotuberculosis were in 100% agreement with the results of standard biochemical tests and PCR-DT. As an alternative to conventional methods, due to its advantages of specificity and speed, the mPCR assay used in this study may successfully be applied for the diagnosis of human and/or animal diseases caused by potentially toxigenic corynebacterial species.

The genus Passiflora L. consists of approximately 530 widely distributed species, including Passiflora edulis, which has drawn interest because of its commercial and agronomic value. Passiflora cincinnata is another important species owing to its long flowering period and resistance or tolerance to diseases and pests. In the present study, the meiotic segregation and pollen viability of an interspecific hybrid (P. edulis × P. cincinnata) and its parents were analyzed. The genomic contents were characterized using chromomycin A3 (CMA3)/4′-6′-diamidino-2-phenylindole (DAPI) staining, fluorescent in situ hybridization with 5S/45S ribosomal DNA (rDNA), genomic in situ hybridization (GISH), and inter-simple sequence repeat (ISSR) markers. The results indicated the diploid chromosome number for the parents and interspecific hybrid was 2n = 18. We also observed regular meiosis, one pair of 5S rDNA sites, and two pairs of 45S rDNA sites that co-localized with two pairs of CMA3 +/DAPI− bands. The GISH data revealed three distinct chromosomal groups in the hybrid. The genetic origins of the interspecific hybrid, and its relationship with its parents were also confirmed using ISSR markers.

The objective of this work was to delineate irrigation management zones using geostatistics and multivariate analysis in different combinations of physical and hydraulic soil properties, as well as to determine the optimal number of management zones in order to avoid overlaping. A field experiment was carried out in a Quartzipsamment, for two years, in an irrigated orchard of table grape, in the Senador Nilo Coelho Irrigation Scheme, in the municipality of Petrolina, in the state of Pernanbuco, Brazil. Soil samples were collected for the determination of soil physico-hydraulic properties. A portable meter was used to measure soil apparent electrical conductivity. Spatial distribution maps were generated using ordinary kriging. Management zones for five different combinations of soil properties were defined using the fuzzy c-means clustering algorithm, and two indexes were applied to determine the optimal number of management zones. Two combinations of soil properties can be used in the management zone planning in order to monitor soil moisture. Made available in DSpace on 2019-10-18T18:09:35Z (GMT).

Epistasis has been shown to have an important role in the genetic control of several quantitative traits in the common bean. This study aimed to investigate the occurrence of epistasis in intra-and inter-pool gene crosses of the common bean. Four elite lines adapted to Brazilian conditions were used as parents, two from the Andean gene pool (ESAL 686; BRS Radiante) and two from the Mesoamerican gene pool (BRSMG Majestoso; BRS Valente). Four F-2 populations were obtained: "A" (ESAL 686 x BRS Radiante), "B" (BRSMG Majestoso x BRS Valente), "C" (BRS Radiante x BRSMG Majestoso), and "D" (BRS Valente x ESAL 686). A random sample of F2 plants from each population was backcrossed to parents and F-1 individuals, according to the triple test cross. Three types of progenies from each population were evaluated in contiguous trials. Seed yield and 100-seed weight were evaluated. Dominance genetic variance was predominant in most cases. However, the estimates of genetic variance may be biased by the occurrence of linkage disequilibrium and epistasis. Epistasis was detected for both traits; however, the occurrence differed among the populations and between the two traits. The results of this study reinforce the hypothesis that epistasis is present in the genetic control of traits in the common bean and suggest that the phenomenon is more frequent in inter-gene pool crosses than in intra-gene pool crosses.

Floral morphology and biology are important characteristics for plant-pollinator interactions and may influence the behavior of these agents. This study aimed to determine which floral attributes of different melon hybrids influence this interaction and, consequently, their attractiveness in simultaneous crops. The study was conducted in the region of Petrolina, State of Pernambuco (PE)/Juazeiro, State of Bahia (BA) and Mossoró, State of Rio Grande do Norte (RN), in areas with the following melon hybrids: Yellow type, Piel de Sapo, Cantaloupe and Galia. For studies on floral morphology and biology, hermaphrodites and male flowers of each hybrid were analyzed for their size and nectar chamber size, pollen and nectar production, anthesis time and flower lifespan. Floral visitors were observed simultaneously in hybrids of three types of melon, from 5:00 a.m. to 6:00 p.m., in the two study sites. Evaluations of the corolla diameter and flower height indicated that the hermaphrodite flowers were larger in size than male flowers in all types of melon investigated, in both study sites. As for nectar chamber, male flowers are larger in width, but smaller in height, compared to hermaphrodite flowers. Regarding the volume of nectar, differences were found between floral types for the hybrids evaluated, in the two study sites; the hermaphrodite flowers produced 2-7 times more nectar than male flowers in all studied hybrids. Observations of visits of Apis mellifera to areas with simultaneous flowering of the three types of melon demonstrated differences in the frequency of visits between hybrids, floral type and foraged resource. Flowers of the hybrids Piel de Sapo and Cantaloupe exhibited larger corolla diameter, larger dimensions of the nectar chamber and greater supply of resources for foraging, which could explain the higher number of visits of bees to their flowers in the sites studied.

Despite its proximity to domestic animals and humans, knowledge of its participation in the epidemiology of some zoonotic agents is substantial. This study aimed to determine the presence of antibodies against Toxoplasma gondii, Neospora spp. and Leptospira spp. in blood samples collected from opossums in 18 municipalities in the state of São Paulo, Brazil, between 2003 and 2008. Blood samples from 343 opossums: Didelphis aurita (n = 256) and Didelphis albiventris (n = 87) were obtained. These were tested to detect antibodies against T. gondii, using the modified agglutination test (MAT-Toto; cutoff≥ 25); Neospora spp., using the indirect fluorescent antibody test (IFAT; cutoff≥ 25); and Leptospira spp., using the microscopic agglutination test (MAT-Lepto; cutoff≥ 100). Frequency of anti-T. gondii, Neospora spp. and Leptospira spp. antibodies were in 22.7%, 1.5% and 3.5%, respectively. The serogroups-serovars of Leptospira spp. presenting positive MAT-Lepto reactions were: Autumnalis-Butembo; Mini-Mini; Ballum-Castellonis; Icterohaemorrhagiae-Icterohaemorrhagiae; Icterohaemorrhagiae-Copenhageni and Grippotyphosa-Grippotyphosa or Bananal. This study demonstrated that these zoonotic agents are circulating in opossum populations in the state of São Paulo. Therefore, investigations regarding the role of marsupials in the epidemiology of each of these diseases should be conducted, especially to understand the behavior of these animals as zoonosis maintenance hosts.

O experimento foi realizado no Departamento de Engenharia Rural, UNESP/Jaboticabal, utilizando, no delineamento, parcelas subdivididas em blocos ao acaso, com quatro repetições. Características agronômicas da soja analisadas: número de días para emergência, índice de emergência, porcentagem de danos, altura de plantas, altura de inserção da primeira vagem, número de vagens por planta, grãos por vagem, porcentagem de plantas sobreviventes e produtividade. Os resultados indicaram que o número de días para emergencia, índice de emergencia e porcentagem de danos não foram influenciados pelas densidades de plantio e profundidade de aplicação dos adubos. Os danos por insetos e aves atingiram valores de 30% de plantas atacadas. A altura das plantas, altura de inserção da primeira vagem, número de vagens por planta e de grãos por vagem não variaram em função da densidade de plantio e profundidade de aplicação do adubo. A produtividade da soja (5.146 kg ha-1) foi similar nas densidades de plantio e profundidade de deposição do adubo. El objetivo de este trabajo fue evaluar las características agronómicas de la soya sembrada en Sistema de Siembra Directa, en función de las densidades de siembra (15, 16 y 20 plantas por metro) y la profundidad de deposición de abono (11, 14 y 17 cm). El experimento fue realizado en el Departamento de Ingeniería Rural, UNESP/Jaboticabal, utilizando, en el delineamiento, parcelas subdivididas en bloques al acaso, con cuatro repeticiones. Características agronómicas de la soya analizadas: número de días de aparición, índice de aparición, porcentaje de daños, altura de plantas, altura de inserción de la primera vaina, vainas por planta, granos por vaina, porcentaje de plantas sobrevivientes y productividad. Los resultados indicaron que el número de días de aparición, índice de aparición y el porcentaje de daños, no fueron influenciados por las densidades y la profundidad de deposición de abono. Los daños por insectos y aves fueron del orden de 30% de plantas atacadas. La altura de plantas, altura de inserción de la primera vaina, vainas por planta y granos por vaina no variaron en relación a la densidad y profundidad de deposición de abono. La productividad de la soya (5.146 kg ha-1) fue semejante en las densidades y profundidades de deposición de abono.

However, these areas still suffer from numerous human impacts, whether by illegal hunting, logging or tourism. Mapping areas of greater human access and its potential effect to wildlife should be considered as strategy for management in protected areas. This study aimed to generate a human accessibility map for the Anchieta Island, for purposes of zoning and management. We evaluated the impact of human presence (tourism) on the occurrence of wildlife at Anchieta Island by using the concept of human accessibility. Accessibility model was correlated with estimated travel-time using Pearson's Correlation and showed significant positive relationship (r = 0.714) between accessibility model and travel time observed in the field. Thus, the accessibility methodology can be a valuable tool to analyze human impacts on wildlife through hunting and logging in protected areas.

No. of bitstreams: 0 Previous issue date: 2011-01-01 No Brasil, as doenças pós-colheita causadas por microorganismos fitopatogênicos se constituem num grave problema e apresentam danos em torno de 80% do valor total da produção de frutas. Na região do Submédio do Vale do São Francisco muitos estudos se fazem necessários para a identificação e controle de doenças fúngicas na pós-colheita de uvas, visando minimizar as perdas nesta etapa. Neste contexto, foram coletados cachos das variedades apirênicas Crimson, Sonaka, Superior e Thompson com o objetivo de identificar e quantificar a incidência de fungos fitopatogênicos no período de julho a outubro de 2009 em cinco propriedades especializadas na produção de uvas finas de mesa para exportação, localizadas nos municípios de Juazeiro - BA e Petrolina – PE. Neste período foram realizadas 10 coletas. No pomar foram utilizadas cinco plantas para amostragem, sendo retirados dois cachos por planta, totalizando 10 cachos por variedade. Posteriormente, estes eram enviados ao laboratório de Fitopatologia da UNEB/ DTCS onde foram colocados separadamente em câmara úmida por 48 horas a uma temperatura média de 23 ºC . Após este período foram realizados isolamentos de bagas e engaço em placas de Petri contendo meio BDA – batata-dextrose-ágar, com 10 repetições, sendo estas, colocadas em bancadas sob condições de laboratório. A partir do 8º dia foram constatadas as presenças de Aspergillus niger, Alternaria alternata, Cladosporium herbarum, Lasiodiploidia theobromae que apresentaram maior incidência e ainda, Rhizopus stolonifer e Penicillium expansum. In Brazil, postharvest diseases caused by pathogenic microorganisms are a major problem that causes damage to around 80% of the total fruit production. In the lower middle Sao Francisco river valley numerous studies on identification and control of fungal diseases during postharvest of grapes are needed, in order to minimize losses in this step. In this context, bunches of seedless varieties 'Crimson', 'Sonaka'; 'Superior' and 'Thompson' were collected from July to November 2009, in order to identify and quantify the incidence of pathogenic fungi. The grapes were collected on five farms which specialize in the production of table grapes for export, all located in Juazeiro - BA and Petrolina - PE. During this period, 10 samples were taken. In the fruit farm five plants were used for sampling, and removal of two bunches of grapes per plant, totaling 10 bunches per variety. Subsequently, they were sent to the laboratory of Plant Pathology at UNEB/DTCS where they were placed separately in a moist chamber for 48 hours at an average temperature of 23 degrees C. After this period, isolations of berries and stems in Petri plates containing PDA - potato-dextrose-agar were carried out with 10 repetitions, which were placed on benches under laboratory conditions. From the 8th day on, the presence of Aspergillus niger, Alternaria alternata, Cladosporium herbarum, Lasiodiploidia theobromae was observed, which presented the highest incidence, as well as Rhizopus stolonifer, Penicillium expansum.
