RESUMO: O girassol produz aquênios e óleo de qualidade, além de servir para produção de silagem, forragem e biodiesel. A modelagem de crescimento permite conhecer o padrão de crescimento da cultura e otimizar o manejo. O objetivo deste trabalho foi caracterizar o crescimento da cultivar de girassol Rhino por meio dos modelos Logístico e Gompertz e fazer considerações a respeito do manejo com base em pontos críticos. Os dados utilizados são oriundos de três ensaios de uniformidade com a cultivar de girassol confeiteiro Rhino, conduzidos na área experimental da Universidade Federal de Santa Maria, Campus Frederico Westphalen, na safra 2019/2020. Foram realizadas 14, 12 e 10 avaliações semanais de altura em 10 plantas, respectivamente, no primeiro, segundo e terceiro ensaio. Os dados foram ajustados em função da soma térmica acumulada. Os parâmetros foram estimados por meio do método dos mínimos quadrados ordinários, usando o algoritmo de Gauss-Newton. A qualidade de ajuste dos modelos aos dados foi medida pelo coeficiente de determinação ajustado, critério de determinação de Akaike, critério bayesiano de informação, e por meio da não linearidade intrínseca e paramétrica. Foram determinados os pontos de inflexão (IP), máxima aceleração (MAP), máxima desaceleração (MDP) e desaceleração assintótica (ADP). As análises estatísticas foram realizadas com Microsoft Office Excel® e o software R. Os modelos descreveram de forma satisfatória a curva de crescimento da altura do girassol, fornecendo parâmetros com interpretações práticas. O modelo Logístico apresenta melhor qualidade de ajuste, sendo o mais adequado para caracterização da curva de crescimento. Os pontos críticos estimados fornecem informações importantes para o manejo da cultura. As plantas daninhas devem ser controladas até o MAP. As aplicações de fertilizantes em cobertura devem ser realizadas entre MAP e IP. O ADP é um indicador de maturidade, após atingir este ponto, as plantas podem ser colhidas para a produção de silagem sem perda de volume e qualidade.

ABSTRACT: Sunflower produces achenes and oil of good quality, besides serving for production of silage, forage and biodiesel. Growth modeling allows knowing the growth pattern of the crop and optimizing the management. The research characterized the growth of the Rhino sunflower cultivar using the Logistic and Gompertz models and to make considerations regarding management based on critical points. The data used come from three uniformity trials with the Rhino confectionery sunflower cultivar carried out in the experimental area of the Federal University of Santa Maria - Campus Frederico Westphalen in the 2019/2020 agricultural harvest. In the first, second and third trials 14, 12 and 10 weekly height evaluations were performed on 10 plants, respectively. The data were adjusted for the thermal time accumulated. The parameters were estimated by ordinary least square’s method using the Gauss-Newton algorithm. The fitting quality of the models to the data was measured by the adjusted coefficient of determination, Akaike information criterion, Bayesian information criterion, and through intrinsic and parametric nonlinearity. The inflection points (IP), maximum acceleration (MAP), maximum deceleration (MDP) and asymptotic deceleration (ADP) were determined. Statistical analyses were performed with Microsoft Office Excel® and R software. The models satisfactorily described the height growth curve of sunflower, providing parameters with practical interpretations. The Logistics model has the best fitting quality, being the most suitable for characterizing the growth curve. The estimated critical points provide important information for crop management. Weeds must be controlled until the MAP. Covered fertilizer applications must be carried out between the MAP and IP range. ADP is an indicator of maturity, after reaching this point, the plants can be harvested for the production of silage without loss of volume and quality.

Abstract: En | Text: En | PDF: En

Abstract The objective of this study was to evaluate the performance of hybrids and the heterosis in crosses of sweet sorghum using juicy sweet male-sterile lines and fertility-restoring lines with and without sensitivity to photoperiod. Thirty hybrids and six controls were evaluated in experiments laid out in a 6 × 6 triple lattice design. The genotypes differed for all traits. The general combining ability (GCA) of the R lines affected all traits, while the GCA of the A lines only affected juice extraction, total soluble solids, and tons of Brix per hectare (TBH). The photosensitive-restoring line CMSXS5022 had the highest positive GCA estimates for the fresh mass production and TBH traits. Heterosis was significant only for days to flowering and plant height. Overall, the photoperiod-sensitive hybrids stood out. The development of male-sterile lines requires better complementarity from restoring lines to reap the benefits of heterosis.

Resumo Fundamento O interesse pela hipertensão em crianças e adolescentes aumentou desde a atualização do sistema de classificação da pressão arterial para comparar com o sistema de classificação dos adultos, alterando a terminologia de “normal alta” para “pré-hipertensão”. Objetivo O objetivo deste estudo foi analisar a associação da modulação autonômica cardíaca com os níveis pressóricos dos adolescentes. Métodos 203 adolescentes foram agrupados de acordo com a pressão arterial sistólica (PAS) e a pressão arterial diastólica (PAD). Um grupo foi caracterizado como pré-hipertensão, e o outro como normotenso. Foram coletadas características antropométricas, cardiovasculares e de qualidade do sono. Inicialmente, os dados foram submetidos ao teste de normalidade Kolmogorov-Smirnov . As variáveis quantitativas contínuas foram analisadas por meio do teste T de Student não pareado. Para análise das variáveis categóricas, foi utilizado o teste qui-quadrado. Um modelo de regressão logística foi realizado. O nível de significância estabelecido foi p<0,05. Os dados foram expressos como média ± desvio padrão e intervalo de confiança. O software R foi utilizado para análise dos dados. O tamanho do efeito foi calculado com a fórmula de Cohen. Resultados O grupo pré-hipertensão apresentou aumento da entropia de Shannon e diminuição da variância total. Além disso, no modelo de regressão logística, os adolescentes deste grupo tiveram 1,03 mais chances de ter a entropia de Shannon afetada quando a PAS foi ajustada ao gênero, maturação sexual, tempo escolar, idade, circunferência da cintura e qualidade do sono. Conclusão Nossos dados mostram que a modulação autonômica pode desempenhar um papel importante no desenvolvimento da pressão arterial elevada em adolescentes ao controlar fatores como tempo escolar e qualidade do sono.

Abstract Background The interest regarding hypertension among children and adolescents has increased since the blood pressure rating system was updated to be compared with the adult rating system, changing the terminology from “normal high” to “prehypertension”. Objective This study aimed to analyze the association between cardiac autonomic modulation and pressure levels of adolescents. Methods 203 adolescents were grouped according to systolic blood pressure (SBP) and diastolic blood pressure (DBP). One group was characterized as prehypertension, and the other as normotensive. Anthropometric, cardiovascular and sleep quality characteristics were collected. Initially, the data were submitted to the Kolmogorov-Smirnov normality test. Continuous quantitative variables were analyzed using the unpaired Student t-test. For the analysis of categorical variables, a chi-square test was used. A logistic regression model was performed. The level of significance was set at p<0.05. The data were expressed as mean ± standard deviation and confidence interval. The R software was used for data analysis. The effect size was calculated using the Cohen’s formula. Results The prehypertension group showed an increase in Shannon entropy and a decrease in total variance. Also, in the logistic regression model, adolescents in this group were 1.03 times more likely to have Shannon entropy’s affected when SBP was adjusted for gender, sexual maturation, school time, age, waist circumference, and sleep quality. Conclusion Our data show that autonomic modulation may play an important role in the development of elevated blood pressure in adolescents, when controlling for other factors, such as school time and sleep quality.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

RESUMO O objetivo deste estudo foi avaliar a prevalência de infecção odontogênica em crianças escolares brasileiras de baixa renda e analisar a sua associação com as variáveis subjetivas da autopercepção de qualidade de vida relacionada à saúde bucal e dor dentária. Neste estudo transversal, 230 crianças escolares com 8 a 10 anos de idade realizaram exame clínico bucal no qual os índices CPOD/ ceod e PUFA/pufa foram mensurados. Com isso, as crianças responderam individualmente ao Child Perceptions Questionnaire (CPQ810) e relatos de dor dentária foram coletados. Os dados foram estatisticamente analisados utilizandose o teste MannWhitney ou KruskalWallis, com posterior teste da correlação de Dunn e Pearson. Dentre as crianças examinadas, 42,6% apresentavam infecção odontogênica e 80% reportou experiência de dor dentária. A idade (p=0,034) e experiência de dor dentária (p<0,002) das crianças foram associadas à infecção odontogênica, bem como o seu bemestar emocional (p=0,008) e social (p=0,009) e impacto geral na qualidade de vida (p=0,019). Além disso, a intensidade (p<0,001), frequência (p<0,001) e duração (p<0,001) da odontalgia foram correlacionadas com o impacto geral na qualidade de vida da criança. A prevalência de infecção odontogênica permanece elevada em crianças escolares brasileiras. Infecção pediátrica e sua dor relacionada induzem não apenas diversas desordens biológicas, mas também afetam negativamente a autopercepção de qualidade de vida das crianças.

ABSTRACT The aim of this study is to assess the prevalence of odontogenic infection in lowincome Brazilian schoolchildren and evaluate its association with the subjective variables of oral healthrelated quality of life and dental pain. In this crosssectional study, 230 schoolchildren aged eight to ten years old underwent a clinical oral survey in which the DMFT/dmft and PUFA/pufa indexes were measured. Afterward, children responded individually to the Child Perceptions Questionnaire (CPQ810) and selfreports of dental pain were collected. Data were statistically analyzed using MannWhitney or KruskalWallis test with a posttest by Dunn’s and Pearson correlation. Of the children evaluated, 42.6% had odontogenic infection and 80% reported experiencing dental pain. Children’s age (p = 0.034) and past experience of dental pain (p < 0.002) were associated with odontogenic sepsis, in addition to impairment of their emotional wellbeing (p = 0.008), social welfare (p = 0.009) and overall impact on quality of life (p = 0.019). Toothache intensity (p < 0.001), frequency (p < 0.001) and duration (p < 0.001) were correlated to the overall impact on children’s quality of life. The prevalence of odontogenic infection remains high among lowincome Brazilian schoolchildren. Pediatric infection and its related pain induce not only various biological disorders but also impair children’s selfperception of quality of life.

ABSTRACT The objective of this study was to determine prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) values of animal meals used in broiler diets through meta-analysis. A bibliographic review was undertaken with studies conducted in Brazil from 2000 to 2016 to catalogue information on AMEn values and the following chemical elements in the composition of the feedstuffs: crude protein (CP), ether extract (EE), gross energy (GE), mineral matter (MM), calcium (Ca), and phosphorus (P). Groups were also catalogued and formed according to sex and age of birds. Chemical correlations were analyzed, and a multiple linear regression model with the stepwise procedure was used to examine the association between the variables, which were included in the equation as a function of their importance. High and significant correlation coefficients between the independent (GE, MM, CP, EE, Ca, and P) and dependent variable (AMEn) contribute to the understanding of variations in the energy values of these feedstuffs. According to the coefficients of determination, the best equations to estimate AMEn of poultry offal meal and meat and bone meal are AMEn = 6139 − 45.5 CP + 0.356 GE − 123.5 MM ( R 2 = 0.8302 ) and AMEn = 2267 + 19.9 CP + 67.9 EE − 44.4 MM ( R 2 = 0.9021 ) , respectively.

Abstract Dental applications based on the unique characteristics of amorphous calcium phosphate stabilized by casein phosphopeptides (CPP-ACP) have been proposed, as well as the improvement of its properties. Objectives: The objective of this study was to determine the ability of topically applied CPP-ACP from a commercial product to remineralize subsurface lesions when applied for extended periods of time (3 h and 8 h). Material and Methods: Artificially induced carious lesions were produced in 50 bovine enamel blocks previously selected by surface hardness. After treatments with gel without F and CPP-ACP applied for 1 minute (Placebo); 2% NaF neutral gel applied for 1 minute (Fluoride 1 min); CPP-ACP applied for 3 min (ACP 3 min); and CPP-ACP applied for 3 h (ACP 3 h) and for 8 h (ACP 8 h), the enamel blocks were submitted to the remineralization pH-cycling. Surface hardness and synchrotron micro-tomography were used to determine the percentage of surface hardness recovery (%SHR) and to calculate mineral concentration (gHAp.cm−3), respectively. The data were submitted to ANOVA followed by the Student-Newman-Keuls test (p<0.05). Results: Fluoride gel presented higher %SHR followed by ACP 3 min (p<0.001). No difference (p = 0.148) was found for Placebo, ACP 3 h and ACP 8 h groups for %SHR. Fluoride gel showed greater mineral concentration (p<0.001) when compared with the other groups. ACP 3 min demonstrated a significant difference (p<0.001) from ACP 3 h and ACP 8 h. The ACP 3 h and 8 h presented a subsurface lesion with development of laminations in all blocks. Conclusion: In this in vitro study the use of CPP-ACP for extended periods of time did not produce an additive effect in the remineralization process.

RESUMO: O eletrocardiograma computadorizado é um dos meios de diagnóstico utilizado para avaliação do coração e vem sendo cada vez mais presente na rotina veterinária. Este trabalho teve por objetivo definir o padrão eletrocardiográfico de cutias (D. prymnolopha) anestesiadas com cetamina e midazolam. Foram utilizadas 18 cutias clinicamente saudáveis, provenientes do Núcleo de Estudos e Preservação de Animais Silvestres (NEPAS) da Universidade Federal do Piauí. Os animais foram submetidos à contenção química com cloridrato de cetamina a 5% na dosagem de 15mg/kg associado ao midazolam, na dosagem de 1mg/kg, por via intramuscular. Os exames eletrocardiográficos foram realizados pelo método computadorizado, com o eletrocardiógrafo veterinário (Módulo de Aquisição de ECG Para Computador (ECG - PC versão Windows 95) Tecnologia Eletrônica Brasileira (TEB) composto por um circuito eletrônico ligado externamente a um notebook, e de um software instalado no disco rígido do computador. Os valores de duração do complexo QRS, intervalos PR e QT, comparados entre machos e fêmeas, apresentaram diferença significativa. Em milivoltagem a onda R foi o único parâmetro que apresentou diferença significativa entre machos e fêmeas. O peso dos animais também foi significativamente diferente entre os gêneros. O protocolo anestésico mostrou-se bem tolerado pelos animais deste experimento, não ocorrendo quadros de arritmias durante o tempo de monitoramento dos animais.

ABSTRACT: An electrocardiogram is a test that assesses heart electrical activity and is applied more frequently in the veterinary care of wild animals. The present study aimed to define the electrocardiogram pattern of agoutis (Dasyprocta prymnolopha Wagler, 1831) anesthetized with ketamine and midazolam. Eighteen clinically healthy agoutis (D. prymnolopha) were used from the Nucleus for Wild Animal Studies and Conservation (NEPAS) of the Federal University of Piauí, Brazil. The animals were chemically restrained with 5% ketamine hydrochloride at a dose of 15mg/kg and midazolam at a dose of 1mg/kg by intramuscular injection. Electrocardiogram tests were carried out by a computerized method with the veterinary electrocardiogram [Acquisition Model for Computer (ECG - PC version Windows 95) Brazilian Electronic Technology (TEB) consisting of an electronic circuit externally connected to a notebook computer with ECGPC-VET (TEB) software installed on the hard disc. In analysing the EKG results, significant differences were observed for QRS complex duration, PR and QT intervals and for R wave millivoltage between the genders; but we observed a significant influence of weight despite the gender. In the present experiment, the anaesthetic protocol was shown to be well tolerated by the agoutis, and no arrhythmias occurred during the time the animals were monitored. The reference values obtained should be used to better understand the cardiac electrophysiology of the species and for its clinical and surgical management.

RESUMO: O objetivo do trabalho foi avaliar a ocorrência de chuvas na eficiência de diferentes formulações de glyphosate aplicadas de forma isolada e em mistura com o saflufenacil, sobre o controle de Brachiaria decumbens. O estudo foi realizado no primeiro semestre de 2013. Os tratamentos constaram da aplicação isolada de três formulações de glyphosate (Roundup Original, Roundup Transorb R e Roundup WG) a 1.080 g e.a. ha-1 e em mistura com o saflufenacil a 24,5 g i.a. ha-1 + Dash a 0,5% v/v e, seis intervalos de tempo para simulação da chuva: 15; 30; 60; 120; 240 e 360 minutos após a aplicação dos herbicidas e uma testemunha sem chuva. Foram realizadas avaliações visuais de controle das plantas aos 4; 7; 14; 21 e 28 dias após a aplicação dos herbicidas. A mistura de saflufenacil + Dash às formulações de Roundup original, Roundup transorb R e Roundup WG aumentaram a velocidade de controle das plantas de B. decumbens, independente do intervalo de chuva estudado. As formulações de glyphosate (Roundup Transorb R e Roundup WG) aplicados isolados foram afetadas por chuvas que ocorreram logo após a pulverização e quando em mistura com saflufenacil + Dash observou-se efeito sinérgico no controle das plantas daninhas.

ABSTRACT: This study aimed to evaluate the effects of rain on the efficiency of different formulations of glyphosate applied in isolation and in combination with saflufenacil on the control of Brachiaria decumbens. This study was conducted during the first half of 2013. The treatments consisted of an isolated application of three formulations of glyphosate (Roundup Original, Roundup Transorb R, and Roundup WG) at 1,080 g a.e. ha-1 and mixed with saflufenacil at 24.5 g a.e. ha-1 + Dash at 0.5% v/v at six time intervals of simulated rain: 15, 30, 60, 120, 240 and 360 minutes after application of herbicides and a control treatment without rain. We performed visual evaluations of plant control at 4, 7, 14, 21 and 28 days after application of herbicides. The mixture of saflufenacil + Dash with the original Roundup formulations, Roundup Transorb R and Roundup WG increased the control speed of B. decumbens plants regardless of the rain interval studied. The formulations of glyphosate (Roundup Transorb R and Roundup WG) applied in isolation were affected by rains that occurred shortly after spraying. In combination with saflufenacil + Dash, there was a synergistic effect on weed control.

RESUMO: Objetivo: Descrever o perfil do câncer de cólon e reto no Centro-Oeste do Brasil. Métodos: Os dados de incidência foram obtidos dos Registros de Câncer de Base Populacional (RCBP) de acordo com o período disponível. Dados sobre os óbitos foram obtidos do Sistema de Informação em Mortalidade (SIM). As taxas de incidência e mortalidade foram calculadas por gênero e grupos etários. As tendências de mortalidade foram analisadas pelo software Joinpoint. Os efeitos de idade-período-coorte foram calculados no software R. Resultados: As taxas de incidência do câncer de cólon variaram de 4,49 a 23,19/100.000, e a mortalidade, de 2,85 a 14,54/100.000. A incidência do câncer de reto variou de 1,25 a 11,18/100.000; a mortalidade, de 0,30 a 7,90/100.000. As tendências de mortalidade por câncer de cólon mostraram um aumento entre homens em Cuiabá, Campo Grande e Goiânia. Para aqueles abaixo dos 50 anos, o aumento foi de 13,2% em Campo Grande. Para aqueles acima dos 50 anos, houve um aumento significante em todas as capitais. Em Goiânia, a mortalidade por câncer de reto em homens aumentou 7,3%. Para mulheres abaixo dos 50 anos em Brasília, o aumento foi de 8,7%, enquanto que para mulheres acima dos 50 anos em Cuiabá foi de 10%. Conclusão: Os dados de incidência do câncer de cólon e reto no Centro-Oeste do Brasil são limitados. A mortalidade por câncer de cólon tem aumentado para ambos os sexos, mas o mesmo não foi verificado para câncer de reto. Os resultados demonstram a necessidade de programas organizados de rastreamento para esta neoplasia no Centro-Oeste.

ABSTRACT: Objective: To describe the incidence and mortality rates from colon and rectal cancer in Midwestern Brazil. Methods: Data for the incidence rates were obtained from the Population-Based Cancer Registry (PBCR) according to the available period. Mortality data were obtained from the Mortality Information System (SIM) for the period between 1996 and 2008. Incidence and mortality rates were calculated by gender and age groups. Mortality trends were analyzed by the Joinpoint software. The age-period-cohort effects were calculated by the R software. Results: The incidence rates for colon cancer vary from 4.49 to 23.19/100,000, while mortality rates vary from 2.85 to 14.54/100,000. For rectal cancer, the incidence rates range from 1.25 to 11.18/100,000 and mortality rates range between 0.30 and 7.90/100,000. Colon cancer mortality trends showed an increase among males in Cuiabá, Campo Grande, and Goiania. For those aged under 50 years, the increased rate was 13.2% in Campo Grande. For those aged over 50 years, there was a significant increase in the mortality in all capitals. In Goiânia, rectal cancer mortality in males increased 7.3%. For females below 50 years of age in the city of Brasilia, there was an increase of 8.7%, while females over 50 years of age in Cuiaba showed an increase of 10%. Conclusion: There is limited data available on the incidence of colon and rectal cancer for the Midwest region of Brazil. Colon cancer mortality has generally increased for both genders, but similar data were not verified for rectal cancer. The findings presented herein demonstrate the necessity for organized screening programs for colon and rectal cancer in Midwestern Brazil.

R E S U M O Objetivos: Verificar a frequência e a gravidade das lesões que acometem praticantes amadores de corrida. Métodos: O estudo foi conduzido por meio de questionário aplicado a 204 corredores amadores. Foram excluídos do estudo menores de idade e pessoas sem prática de corrida. Número, tipo, topografia e grau de gravidade das lesões, além de idade e sexo, foram os dados coletados. Resultados: Observou-se predomínio de atletas do sexo masculino, idade média de 32,6 ± 9,3 anos com variação de 18 a 68 anos. As lesões foram classificadas como leves e afastaram o atleta da prática de corrida por menos de oito dias. Entorses, lesões bolhosas e escoriações foram as lesões mais frequentes, localizadas mais frequentemente nos membros inferiores, com predomínio nos pés. Conclusão: Na prática de corrida, entorses, lesões bolhosas e escoriações são frequentes,porém são leves e acometem mais os membros inferiores.

ABSTRACT OBJECTIVES: To determine the frequency and severity of injuries that affect amateur runners. METHODS: This study was conducted by means of a questionnaire applied to 204 amateur runners. Individuals who were under the age of 18 years and those who were unpracticed runners were excluded. The data gathered comprised the number, type, site and degree of severity of the injuries and the individuals' age and sex. RESULTS: It was observed that male athletes predominated. The mean age was 32.6 ± 9.3 years with a range from 18 to 68 years, and the injuries were classified as mild, keeping the athlete away from practicing running for fewer than eight days. Sprains, blisters and abrasions were the most frequent injuries, located most often on the lower limbs and predominantly on the feet. CONCLUSION: In practicing running, sprains, blisters and abrasions occur frequently, but are mild injuries. They mostly affect the lower limbs.

Abstract: En | Text: En | PDF: En

Competition between weeds and crops results in a lower availability of some resources to crop species, which causes deficiencies, such as water and nutritional deficiencies and low light quality or quantity. The aims of this study were to evaluate the effects of Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster, cv. Xaraes (brachiaria) emergence times comparing with corn (Zea mays L.), in addition to the fertilization and application of different nicosulfuron and atrazine herbicides levels, on the physiological characteristics of intercropped species. The physiological characteristics Brachiaria plants that were treated with herbicides were negatively affected. The emergence time of Brachiaria plants in comparison with corn altered the physiological characteristics of both. The Brachiaria plants that emerged before corn presented higher photosynthetic and transpiration rates and reduced the intensity of these characteristics in corn. Thus, the Brachiaria plants that emerged before the corn crop presented a higher physiological efficiency, and they were more competitive than the weeds that emerged during other seasons.

Um grande pterossauro (MN 6594-V) da Formação Romualdo (Aptiano/Albiano), Grupo Santana, Bacia do Araripe, é descrito. O espécime é referido a Tropeognathus cf. T. mesembrinus principalmente pela crista frontoparietal baixa e obtusa, por um número comparativamente baixo de dentes e pela inclinação da porção dorsal da região occipital. Duas distintas medidas de envergadura para pterossauros são introduzidas: a envergadura maximizada (maxws), que consiste essencialmente no dobro da soma de todos os elementos da asa e o comprimento da escápula ou do coracóide (o menor de ambos), e a envergadura normal (nws), que aplica um fator de redução (rdc) à envergadura maximizada para compensar as curvaturas naturais da asa. Para pteranodontóides o rfc sugerido é de 5%. No caso de MN 6594-V, maxws e nws correspondem a 8,70 m e 8,26 m, respectivamente, o que faz deste espécime o maior pterossauro coletado do Gondwana até hoje. A extremidade distal de um úmero de maior tamanho (MCT 1838-R) e uma asa parcial (MPSC R 1395) também são aqui descritos, mostrando que pterossauros grandes ou gigantescos formaram uma parcela significativa da fauna de pterossauros da Formação Romualdo. Finalmente, alguns comentários sobre a estabilidade nomenclatural para os depósitos de Santana são feitos.

A very large pterosaur (MN 6594-V) from the Romualdo Formation (Aptian/Albian), Santana Group, Araripe Basin, is described. The specimen is referred to Tropeognathus cf. T. mesembrinus mainly due to the presence of a low and blunt frontoparietal crest, the comparatively low number of teeth and the inclined dorsal part of the occipital region. Two distinct wingspan measurements for pterosaurs are introduced: the maximized wingspan (maxws), which essentially consists of doubling the addition of all wing elements and the length of the scapula or the coracoid (the smaller of the two), and the normal wingspan (nws), which applies a reducing factor (rfc) to the maximized wingspan to account for the natural flexures of the wing. The rfc suggested for pteranodontoids is 5%. In the case of MN 6594-V, the maxws and nws are 8.70 m and 8.26 m, respectively, making it the largest pterosaur recovered from Gondwana so far. The distal end of a larger humerus (MCT 1838-R) and a partial wing (MPSC R 1395) are also described showing that large to giant flying reptiles formed a significant part of the pterosaur fauna from the Romualdo Formation. Lastly, some comments on the nomenclatural stability of the Santana deposits are presented.

A melissa (Melissa officinalis) é uma planta medicinal comumente usada como calmante e ingerida na forma de chá. Para otimizar sua produção, este trabalho objetivou avaliar o efeito de diferentes doses de esterco bovino, com relação ao fertilizante mineral na produção de biomassa foliar e teor de óleo essencial. O experimento foi conduzido na Universidade Federal de Uberlândia e no Instituto Agronômico de Campinas. O delineamento estatístico foi de blocos casualisados com seis tratamentos (0, 1, 2, 4, 8 kg m-2 de esterco bovino e 30 g m-2 de NPK 4-14-8), em quatro repetições. O óleo essencial foi extraído por hidrodestilação em equipamento tipo Clevenger modificado. As doses de esterco bovino influenciaram a altura de plantas, massa fresca total e massa seca foliar por planta e por hectare. As duas formas de adubação foram superiores à testemunha para praticamente todas as variáveis, exceto em relação ao comprimento e largura foliar, teor de óleo na matéria seca e fresca foliar. Conclui-se que a melissa responde à adubação orgânica com esterco bovino e adubação mineral para produção de biomassa.

Lemon balm (Melissa officinalis) is a medicinal plant commonly used as a sedative and ingested as a tea. Studies on agricultural practices are required to optimize its yield. To optimize its production, this study evaluated the effect of different doses of organic fertilizer (cow manure) in comparison to mineral fertilizer on biomass production and essential oil yield. The experiment was carried out at the Federal University of Uberlândia, Minas Gerais state, Brazil, and at the Agronomic Institute of Campinas, São Paulo state, Brazil. The experimental design was randomized blocks with six treatments (0, 1, 2, 4, 8 kg m-2 of manure and 30 g m-2 of NPK 4-14-8), and four replications. Hydro-distillation was done with a modified Clevenger distiller for essential oil extraction. Cattle manure influenced plant height, total fresh and dry mass of leaves, per plant and per hectare. The two fertilization forms were better than the non-fertilized control for all variables, except for leaf length and width and oil content in the leaf fresh and dry matter. It can be concluded that lemon balm is responsive to organic fertilization with manure and mineral fertilization for biomass production.
