The aim of this work was to identify and quantify the metabolites present in the roots of Combretum lanceolatum inoculated with its endophytic fungi. The metabolomics was accomplished using the 1H nuclear magnetic resonance (NMR) spectral data and evaluated via rNMR software and Madison Metabolomics Consortium Database (MMCD). The principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) showed that plants inoculated with Trichoderma spirale (Ts) present differentiation and discrimination over the time compared to control. Seven days after Ts fungal inoculation, 15 metabolites were identified at different concentrations comparing to the control plants. The plants inoculated with Ts fungus present the metabolites spermidine and pantothenate in higher concentrations and 3-hydroxybutyric acid and b-alanine in lower concentrations compared to control plants, indicating any response to biotic stress. These metabolites are involved in various plant processes, including secondary metabolites biosynthesis, energy metabolism and self-defense. Therefore, this work demonstrates the diversification of primary metabolites composition influenced by endophytes inoculation.

ABSTRACT The aim of the present study was to analyze the relationship between the highest value of the Reactive Strength Index (RSI) and sprint acceleration in basketball players. Seven basketball players (age 19 years± 2.16, height 1.85 meters± 0.04, body mass 80.16 kg± 12.20, BMI 24.21 km/m2± 3.33 and practice time 6.28 years± 2.75) at the regional level, from the city of João Pessoa, Paraíba, were evaluated in the reactive strength index and acceleration in the sprint, at 0-10, 0-20 and 10-20 meters, measured by a contact platform and photocells, respectively. Data were analyzed in SPSS 22.0 software quantitatively through mean and standard deviation. The Shapiro-Wilk normality test was used and, after the result of non-normality of the data, the Spearman correlation. Negative and weak correlations were found between RSI and 0-10 meters (r= -0.107, p= 0.819), and negative and moderate correlation between RSI and 0-20 (r= -0.429, p= 0.337) and 10-20 meters (r= -0.214, p= 0.645). It can be concluded that experienced athletes may have a moderate correlation between the highest RSI values and a 20-meter sprint.

RESUMO O objetivo do presente estudo foi analisar a correlação entre o maior valor do Índice de Força Reativa (IFR) e a corrida de aceleração em atletas de basquetebol. Sete atletas de basquetebol (idade 19 anos± 2.16, estatura 1.85 metros± 0.04, massa corporal 80.16 kg± 12.20, tempo de prática 6.28 anos± 2.75) a nível regional, da cidade de João Pessoa, Paraíba, foram avaliados no índice de força reativa e na aceleração no sprint em 20 metros, em 0-10, 0-20 e 10-20 metros, medidas por um tapete de contato e fotocélulas, respectivamente. Os dados foram analisados no software SPSS 22.0, apresentados em média e desvio padrão. Foi aplicado o teste de normalidade de Shapiro-Wilk e, após o resultado de não normalidade dos dados, utilizou-se o teste de correlação de Spearman. Houve correlação negativa fraca entre o IFR e 0-10 metros (r= -0.107, p= 0.819) e negativa moderada entre o IFR e 0-20 (r= -0.429, p= 0.337) e 10-20 metros (r= -0.214, p= 0.645). Pode-se concluir que atletas experientes podem apresentar correlação moderada entre os maiores valores de IFR e a corrida de velocidade nos 20 metros.

ABSTRACT Cardiovascular risks are now an epidemiological reality among adults and teenagers. This scenario leads to impairments in quality of life and represents a burden in healthcare and government costs. This study aimed to evaluate the association between risk factors for cardiovascular diseases, quality of life, daytime sleepiness, fatigue, and anthropometric parameters on university students in Fortaleza/CE, Brazil. It was a descriptive, crossectional, correlational study, made through epidemiological assessment in young university students, with primary data and quantitative analysis. The results showed a negative influence of daytime sleepiness and fatigue on the overall quality of life. Functional capacity, a component of the quality of life, which represents the ability to perform tasks and activities in their life, and limitations due to emotional aspects could impact a person's well-being and health. Moreover, excessive daytime sleepiness showed a strong correlation with almost all domains of quality of life. It was found that although volunteers did not show a low quality of life, fatigue levels and sleepiness presented as relevant variables. There is a need to comprehend and control these variables to promote students’ health and, consequently, to live healthier adulthood.

Abstract Background: The study of the interactions between equipment, application methods, and spray mixtures is fundamental to optimize the application of pesticides. The determination of the best combination of these factors can reduce the drift during the application of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). Objective: The objective this paper is to study the influence of nozzle models, working pressures, and surfactant adjuvant in reducing the drift of 2,4-D. Methods: The spectrum of nozzle drops was determined for a conventional flat jet; flat jet with air induction; double plane jet with air induction; deflector flat jet with air induction; and an empty cone with air induction at pressures of 200, 300, 400, and 500 kPa. This was quantified in a wind tunnel with four drifts: water; water + surfactant adjuvant; water + 2,4-D; and water + 2,4-D + surfactant adjuvant, applied by the five nozzle models at four working pressures. The data was evaluated by analysis of variance and, when significant, by the Tukey test and regression at 5% significance level. Results: The interactions between the nozzle models, working pressure, and spray mixture directly influenced the 2,4-D drift. Conclusions: The use of surfactant adjuvant must be carried out carefully, according to the nozzle model, working pressure, and spray mixture. The conventional single fan jet nozzle is more sensitive to increased working pressure and has a high potential to cause drift compared with the models with air induction.

Resumo: A bacia do rio Munim é uma das principais drenagens da unidade Hidrológica do Maranhão, mas existem poucos estudos publicados que enfoquem levantamentos ictiológicos e trabalhos taxonômicos dentro desta bacia. O presente estudo tem como objetivo fornecer um inventário de espécies de peixes da Mata da Itamacaoca, uma das poucas áreas protegidas urbanas da bacia do alto rio Munim, comparando a ictiofauna com outras listas realizadas na bacia do alto rio Munim. Foram realizadas 42 expedições de coleta, a amostragem foi conduzida em cinco locais de coleta distribuídos dentro dos limites da Mata de Itamacaoca, bacia do alto rio Munim. Índices de diversidade foram calculados e modelos lineares generalizados (GLMs) foram empregados para avaliar diferenças na riqueza de espécies, diversidade e equitabilidade dependendo da estação e localização em relação à parede da barragem do reservatório. A fim de visualizar as diferenças da comunidade de peixes, escalonamento multidimensional não métrico (nMDS) e um PERMANOVA unilateral foi usado para entender se os fatores de local, estação e localização da parede da barragem afetavam a composição da comunidade de peixes. Um total de seis ordens, 13 famílias e 23 espécies de peixes foram encontradas, sendo que a ordem com maior riqueza de espécies, considerando todos os trechos, foi Characiformes seguida por Cichliformes. A espécie mais abundante foi Nannostomus beckfordi, enquanto Pimelodella parnahybae e Hoplerythrinus unitaeniatus foram as espécies mais raras amostradas. Não houve espécies exóticas invasoras coletadas na área de estudo. A riqueza de espécies foi significativamente maior abaixo da parede da barragem, mas não houve outras diferenças significativas nos índices de diversidade em relação à estação do ano ou localização. A composição da comunidade de peixes foi significativamente diferente acima e abaixo da parede da barragem, e foi significativamente afetada pelo local de amostragem. A estação do ano não afetou a comunidade de peixes. Este estudo corrobora outros estudos realizados na Unidade Hidrológica Maranhão sensu Hubbert and Renno (2006), que a composição ictiofaunística e taxonomia das espécies desta região enfrentam grandes déficits de dados. Impactos antropogênicos, este estudo pode ser uma linha de base para comparar ambientes semelhantes em toda a região.

Abstract: The Munim River basin is one of the main river drainages of the Hydrological unit Maranhão, but there are few published studies which focus on ichthyological surveys and taxonomic work within this basin. The present study aims to provide a fish species inventory of the Mata da Itamacaoca, one of the few urban protected areas from the upper Munim River basin, comparing the ichthyofauna with other lists by conducted at the upper Munim River basin. A total of 42 collection expeditions were conducted, the sampling was conducted at five collecting sites distributed within the boundaries of Mata de Itamacaoca, upper Munim River basin. Diversity indices were calculated and generalised linear models (GLMs) were employed to assess differences in species richness, diversity and evenness depending on season and location in relation to the reservoir dam wall. In order to visualize fish community differences, non-metric multidimensional scaling (nMDS) and a one-way PERMANOVA was used to understand whether factors of site, season and location to the dam wall had an effect on fish community compositions. A total of six orders, 13 families, and 23 fish species were found, and the order with the highest species richness, considering all reaches, was Characiformes followed by Cichliformes. The most abundant species was Nannostomus beckfordi, while Pimelodella parnahybae and Hoplerythrinus unitaeniatus were the rarer species sampled. There were no alien invasive species collected within the study area. Species richness was significantly higher below the dam wall, but there were no other significant differences in diversity indices with regards to season or location. Fish community composition was significantly different above and below the dam wall and was significantly affected by sampling site. Season did not have an effect on fish community. This study corroborates other studies conducted in the Unidade Hidrológica Maranhão sensu Hubbert and Renno (2006), that the ichthyofaunal composition and taxonomy of species within this region face major data deficits, anthropogenic impacts, this study may be a baseline for comparing similar environments throughout the region.

Abstract Tegumentary leishmaniasis (TL) diagnosis is challenging due to the lack of a gold standard diagnostic tool. The diagnosis is significantly harder in regions where visceral leishmaniasis (VL) is also prevalent since immunological tests may present cross-reactivity. A cirrhotic patient from an endemic Brazilian region for TL and VL presented with atypical cutaneous lesions, a usual clinico-laboratory feature of VL (including a positive rk39 test result), but he was diagnosed with TL histopathologically; VL was ruled out by necropsy. Physicians working in co-prevalent areas should be aware of atypical features, unusual clinical course, and unexpected laboratory findings of leishmaniasis.

RESUMO Diferentemente de outras variáveis mais comuns relacionadas à saúde, a aptidão cardiorrespiratória (ACR) não é medida constantemente na população em geral. Sua omissão caracteriza numa perda de informação relevante. Com isso os objetivos do presente estudo foram: a) caracterizar a ACR da população brasileira de 20 a 59 anos, desenvolvendo valores normativos através de uma equação para estimar o consumo máximo de oxigênio (VO2Máx) sem a realização de exercícios; e b) verificar a associação de menores níveis de ACR com a prevalência de doenças crônicas. Ao todo, 32.531 indivíduos compuseram a amostra oriunda da Pesquisa Nacional de Saúde (PNS-IBGE-2013). Apenas variáveis auto-relatadas foram incluídas a partir da equação de Wier et al. (2006): sexo, idade, nível de atividade física e Índice de Massa Corporal. A média de VO2Máx foi estimada como 44,6; 39,3; 34,8 e 30,6 ml/kg/min (homens) e 34,5; 29,6; 25,4 e 21,1 ml/kg/min (mulheres) com idades 20-29; 30-39; 40-49 e 50-59. Os valores de percentil 20 e 80 foram estabelecidos como os extremos de muito baixa e muito alta ACR. A baixa aptidão demonstrou significativamente 33% maiores chances de prevalência de doença cardiovascular, 89% de diabetes mellitus e 67% de hipertensão arterial independentemente de sexo, idade, e presença de obesidade, o que parece corroborar a qualidade da equação utilizada.

ABSTRACT Unlike other more common health-related variables, cardiorespiratory fitness (CRF) is not frequently measured in the general population. This omission characterizes a loss of relevant information. Thus, the objectives of the present study were: a) to characterize the CRF of the Brazilian population aged 20 to 59 years and to develop normative values using a non-exercise equation for predicting maximal oxygen uptake (VO2max), and b) to verify the association between lower levels of CRF and the prevalence of chronic diseases. A total of 32,531 individuals from the National Health Survey (NHS-IBGE-2013) composed the sample. Only self-reported variables were included in the equation of Wier et al. (2006): sex, age, physical activity level, and body mass index. The mean predicted VO2max was 44.6, 39.3, 34.8 and 30.6 ml/kg/min for men, and 34.5, 29.6, 25.4 and 21.1 ml/kg/min for women aged 20-29, 30-39, 40-49 and 50-59 years, respectively. The 20th and 80th percentiles were established as the extremes (very low and very high CRF). Participants with low fitness had a 33% higher chance of cardiovascular disease, an 89% higher chance of diabetes mellitus, and a 67% higher chance of hypertension, regardless of sex, age and presence of obesity, which seem to corroborate the quality of the equation.

RESUMO As lesões dos músculos isquiotibiais (IT) são as mais comuns do esporte e estão correlacionadas com um longo tempo de reabilitação e apresentam uma grande tendência de recidiva. Os IT são compostos pela cabeça longa do bíceps femoral, semitendíneo e semimembranoso. A apresentação clínica do paciente depende das características da lesão, que podem variar desde um estiramento até avulsões da inserção proximal. O fator de risco mais reconhecido é a lesão prévia. A ressonância magnética é o exame de escolha para o diagnóstico e classificação da lesão. Muitos sistemas de classificação têm sido propostos; os mais atuais objetivam descrever a lesão e correlacioná-la com o seu prognóstico. O tratamento das lesões é conservador, com o uso de medicações anti-inflamatórias na fase aguda, seguido do programa de reabilitação. As lesões por avulsão proximal têm apresentado melhores resultados com o reparo cirúrgico. Quando o paciente está sem dor, apresenta recuperação da força e do alongamento muscular e consegue fazer os movimentos do esporte, está apto para retornar à atividade física. Programas de prevenção, baseados no fortalecimento excêntrico da musculatura, têm sido indicados tanto para evitar a lesão inicial como a recidiva.

ABSTRACT Hamstring (HS) muscle injuries are the most common injury in sports. They are correlated to long rehabilitations and have a great tendency to recur. The HS consist of the long head of the biceps femoris, semitendinosus, and semimembranosus. The patient's clinical presentation depends on the characteristics of the lesion, which may vary from strain to avulsions of the proximal insertion. The most recognized risk factor is a previous injury. Magnetic resonance imaging is the method of choice for the injury diagnosis and classification. Many classification systems have been proposed; the current classifications aim to describe the injury and correlate it to the prognosis. The treatment is conservative, with the use of anti-inflammatory drugs in the acute phase followed by a muscle rehabilitation program. Proximal avulsions have shown better results with surgical repair. When the patient is pain free, shows recovery of strength and muscle flexibility, and can perform the sport's movements, he/she is able to return to play. Prevention programs based on eccentric strengthening of the muscles have been indicated both to prevent the initial injury as well as preventing recurrence.

ABSTRACT Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigation was to evaluate the effects of this compost on soil fertility and on the nutritional status and yield of the corn crop. The experiment was conducted in a Haplic Luvisol in a randomized block design with six treatments and five application rates of the organic compound in Mg ha-1: 3 (half the standard rate), 6 (standard rate), 9 (one and a half times the standard rate), 12 (twice the standard rate), and 24 (four times the standard rate) and an additional treatment with mineral fertilizers (110, 50 e 30 kg ha-1 of N, P2O5 and K2O, respectively), with four blocks. Evaluations were performed for two harvests of rainfed crops, measuring soil fertility, nutritional status, and grain yield. The compost increased P, K, Na and Zn values in the 0.00-0.20 m layer in relation of mineral fertilization in 616, 21, 114 and 90 % with rate 24 Mg ha-1 in second crop. Leaf N, Mg, and S contents, relative chlorophyll content, and the productivity of corn kernels increased in 27, 32, 36, 20 e 85 %, respectively, of low rate (3 Mg ha-1) to high rate (24 Mg ha-1) with of application of the compost. Corn yield was higher with application of organic compost in rate of 24 Mg ha-1 than mineral fertilizer combination in second crop.

Abstract Acetogenins are secondary metabolites derived from the polyketide pathway and their potential role as chemotaxonomical markers for red algae belonging to the Laurencia complex has been long pointed out. C15 acetogenins from algae are quite different from plant acetogenins: they are usually halogenated, and have an enyne or a bromoallene terminal group. Since they were first reported, laurencin and other algal acetogenins have inspired great curiosity among natural product chemists and also those working with synthesis. This paper reviews the literature about C15 acetogenins, focusing on their distribution, chemical and biological aspects, including their reported biological activities.

Objective Evaluate intraoperative cooling of the oropharynx to reduce postoperative pain in tonsillectomy using monopolar electrocautery. Methods Sixty-six patients, age 1 to 12 years, were selected for the study, 33 in the control group and 33 in the experimental group. After randomization, patients underwent subcapsular dissection and hemostasis with monopolar electrocautery. Patients in the experimental group had the oropharynx cooled after tonsil dissection and hemostasis for 10 minutes. The procedure was done through the oral cavity by irrigation with 500 mL of 0.9% saline, in temperatures between 5°C and 10°C, for 5 minutes. The evaluation of postoperative pain was made with the pain visual analog scale (VAS) for 10 days. As complementary data on the evaluation of pain, we recorded daily use of ketoprofen for pain relief. Results Pain after tonsillectomy assessed by VAS was significantly lower in the experimental group at days 0, 5, and 6 (p < 0.05). There were no differences in the use of ketoprofen between the groups. Conclusion Cooling of the oropharynx after tonsillectomy promotes clinically significant reduction in postoperative pain, without additional complications.
