Abstract This study aimed to analyze the root and root canal morphology of mandibular first and second molars using CBCT images. A total of 2,400 mandibular molars exams were selected from 600 patients aged between 18 and 75 years. The number of roots, number of root canals, and root canal configuration according to the Vertucci classification were verified. Overall, 94.92% of mandibular first molars and 90.17% of mandibular second molars had two separate roots. Among the biradicular molars, the first molars showed a greater incidence of type IV canals in the mesial root and type I in the distal root. In the second molars, the most common canal form was type IV in the mesial root and type I in the distal root. In the triradicular molars, the type IV and type I configurations were the most common in the mesial root of the first molar and second molar, respectively. In both triradicular molars, there was a prevalence of type I canal in the distal and DL roots. Statistical analysis was performed at a significance level of 0.05. The number of roots was correlated with gender (Spearman test), and the canal's configuration with gender and bilaterality (Wilcoxon test). The subpopulation studied has a high incidence of bilateral symmetry and mandibular molars with two roots with two distinct mesial canals and one distal canal. The bilateral configuration is possible to estimate the number of canals, especially in images that are difficult to visualize, such as atresic canals.

Objective: To test the hypothesis that genetic variations of cannabinoid receptors contribute to the pathophysiology of cognitive deficits in schizophrenia. Methods: In this genetic association case-control study, cannabinoid receptor polymorphisms CNR1 rs12720071 and CNR2 rs2229579 were tested for association with neurocognitive performance in 69 patients with schizophrenia and 45 healthy controls. Neurocognition was assessed by the Brief Assessment of Cognition in Schizophrenia (BACS). Results: We found a consistent association between CNR1 rs12720071 polymorphism and the cognitive performance of patients in several cognitive domains. Patients with C/C polymorphism presented significantly worse performance in motor speed, verbal fluency, attention/processing speed and reasoning/problem solving. Conclusion: Although limited, our data support the hypothesis that CNR1 variations may be associated with the pathogenesis of cognitive deficits of schizophrenia.

Abstract: En | Text: En | PDF: En

The NaCl and KCl diffusion in the film formed on the cheese surface during salting was simulated by the finite element method. The time and salts concentration values on the cheese surface were determined, tabulated, and presented to the multilayer perceptron neural network (MLP) for the regression modeling. The samples were divided into 70, 15 and 15% for training, testing, and validation, respectively. The networks with the best performance showed 5 to 12 hidden layers. The Tukey’s test showed that there was no significant difference, at the 5% level, between the time value used and the mean value modeled for training, testing, and validation for the NaCl. For the KCl, a significant difference was observed only for 2 training samples and 1 test sample. Sensitivity analysis showed that the discrete variable Z, which represents the static and dynamic systems, was the most important in the models’ construction.

Abstract Phalaenopsis and Dendrobium do not grow and flower well with 100% ammonium (NH4-N); and there are detailed studies on the effects of nitrate (NO3-N) and ammonium ratios on the flowering, but no information about accumulation of other nutrients and the effects of ammonium toxicity on orchids. For this reason, two experiments were carried out with orchids: Phalaenopsis ‘Golden Peoker’ and Dendrobium ‘Valentine’. Six months after acclimatization the plants were transplanted to individual plastic vessels and the treatments consisted of five ratios (%) of nitrate / ammonium (0/100, 25/75, 50/50, 75/25, 100/0). The sources of NO3-N and NH4-N were calcium nitrate and ammonium sulfate, respectively. After 12 months treatment, when the plants were beginning to issuance of flower stem, the accumulation of: N, P, K, Ca and Mg in the shoot and biometric variables were evaluated for both species. The NH4-N ratio of 40% and 50% of the total nitrogen benefited the growth of Phalaenopsis and Dendrobium, respectively. The application of higher proportions of ammonium resulted in decreased N, K, Ca and Mg absorption, index of green color and increased leakage of electrolytes in Phalaenopsis and Dendrobium. NH4-N proportions greater than 75% for 12 months caused toxicity in Phalaenopsis and Dendrobium.

ABSTRACT One of the main factors that determine the success of decision-making in the fields is the climatic factor. This way, the geostatistical techniques have been used to represent and understand the spatial or temporal dynamics of meteorological parameters. Therefore, the aim of this research was to represent temporally through thematic maps, the average daily behavior for meteorological variables and the hydric balance for the municipality of Patos de Minas - MG. The climatic data were acquired from the automatic station INMET from the years 1990 to 2015. Later, it was calculated the evapotranspiration and the hydric balance for different capacities of available water in the soil (CAW): 24 mm, 48 mm, 80 mm and 112 mm. The climate variables showed temporal dependence, and through the thematic maps, derived from the ordinary Kriging, it was possible to identify the seasons of the year that are favorable for the production for the different crop groups.

RESUMO: O tamanho e a função atrial esquerda estão relacionados em humanos com eventos cardiovasculares adversos e prognóstico nas principais cardiopatias. Na doença valvar crônica de mitral (DVCM) em cães, o átrio esquerdo é a câmara cardíaca mais comprometida. Portanto, os objetivos deste estudo foram comparar os principais parâmetros de aumento atrial esquerdo (relação átrio esquerdo/aorta, índice do diâmetro atrial esquerdo e índice do volume atrial esquerdo) e função contrátil de átrio esquerdo (velocidade máxima e integral de velocidade da onda A do fluxo transvalvar mitral, fração atrial e força de ejeção atrial) nos diferentes estágios da doença valvar; correlacionar diâmetro e volume atrial esquerdo e os índices de função contrátil atrial esquerda com as variáveis ecocardiográficas preditivas de insuficiência cardíaca em cães (velocidade máxima da onda E do fluxo transvalvar mitral, relação E/TRIV, relação E/E’par e relação E/A). Os resultados mostraram que com a evolução progressiva da doença valvar crônica de mitral, ocorre dilatação progressiva do átrio esquerdo, bem caracterizada pela relação átrio esquerdo/aorta e pelo índice de volume atrial esquerdo. O índice do diâmetro atrial esquerdo, o índice de volume atrial esquerdo e a relação átrio esquerdo/aorta correlacionam-se, positivamente, com a velocidade da onda E e com a relação E/TRIV, que são importantes índices de função diastólica. Os índices de função contrátil do átrio esquerdo aumentam à medida que a DVCM evolui. Os índices de função contrátil do átrio esquerdo apresentam correlação positiva com os índices de pressão de enchimento ventricular esquerdo, exceção feita à fração atrial.

ABSTRACT: In humans, left atrial enlargement and reduced contractile functions are associated with adverse cardiovascular events and a poor prognosis in many dilatation of the left atrium occurs with the gradual evolution of chronic mitral valve disease and is well diseases. The left atrium is the most compromised cardiac chamber in dogs with chronic mitral valve disease (CMVD). Therefore, this study aimed to compare the main parameters of left atrial enlargement (left atrium/aorta ratio, left atrial diameter and volume indices) and contractile function (transmitral flow peak velocity A wave and time velocity integral, atrial fraction, and atrial ejection force) at different stages of valve disease, and correlate the left atrial diameter, volume, and contractile function indices with echocardiographic variables predictive of heart failure in dogs (transmitral flow peak velocity E wave, E wave/IVRT ratio, E wave/E´wave ratio, and E wave/A wave ratio). The results showed that progressive characterized by the left atrium/aorta ratio and left atrium volume index. The left atrial diameter and volume indices and left atrium/aorta ratio correlated positively with the transmitral flow peak velocity E wave and E wave/IVRT ratio, which are important indices of diastolic function. The left atrial contractile function indices increased as CMVD evolved. Except for the atrial fraction, the left atrial contractile function indices correlated with the left ventricular filling pressure indices.

Abstract The attention to nuclear clustering has been renewed due to the study of weakly bound nuclei at the drip lines. In particular, clustering structural properties in medium-mass systems have been studied by looking at the competition between the evaporation and pre-equilibrium particle emission in central collisions. Although for light nuclei at an excitation energy close to the particle separation value there are experimental evidence of such structure effects, this is still not the case for heavier systems since the determination of pre-formed clusters within nuclear matter is less obvious. Two systems, leading to the same 81Rb* compound nucleus, have been studied at the same beam velocity 16 AMeV: 16O + 65Cu and 19F + 62Ni. The experiment has been performed using the GARFIELD + RCo detection system installed at the Legnaro National Laboratories.Light charged particles energy distributions and multiplicities have been compared with different statistical and dynamical model calculations. From the first comparison between the two systems a difference in the fast α-decay channel has been evidenced, which can be related to the difference in the projectile structure. Recent data analysis results and comparisons with model calculations are presented in this contribution.

Resumen La atención a la agrupación nuclear se ha renovado debido al estudio de núcleos débilmente unidos en las líneas de goteo. En particular, se han estudiado las propiedades estructurales del agrupamiento en sistemas de masa media al observar la competencia entre la evaporación y la emisión de partículas de preequilibrio en colisiones centrales. Aunque para núcleos ligeros a una energía de excitación cercana al valor de separación de la partícula hay evidencia experimental de tales efectos de estructura, este no es el caso para sistemas más pesados ya que la determinación de agrupamientos preformados dentro de la materia nuclear es menos obvia. Se han estudiado dos sistemas, que conducen al mismo núcleo compuesto 81Rb *, a la misma velocidad de haz 16 AMeV: 16O + 65Cu y 19F + 62Ni. El experimento se ha realizado utilizando el sistema de detección GARFIELD + RCo instalado en los Laboratorios Nacionales Legnaro. Las distribuciones de energía y las multiplicidades de partículas de carga ligera se han comparado con diferentes cálculos de modelos estadísticos y dinámicos. Desde la primera comparación entre los dos sistemas, se ha evidenciado una diferencia en el canal de desintegración α rápida, que se puede relacionar con la diferencia en la estructura del proyectil. En esta contribución se presentan los resultados del análisis de datos recientes y las comparaciones con los cálculos del modelo.

RESUMO O cobre (Cu) é um micronutriente essencial aos vegetais, mas em excesso torna-se fitotóxico para as plantas. Nesse contexto, o objetivo deste trabalho foi avaliar o crescimento e as respostas fisiológicas de espécies arbóreas expostas a diferentes concentrações de cobre no solo. Foram realizados três experimentos, sendo um para cada espécie florestal em estudo: Myroxylon peruiferum (Óleo Bálsamo), Hymenaea courbaril (Jatobá) e Peltophorum dubium (Canafístula), com as mesmas doses de cobre (0, 50, 100, 200 e 400 mg kg-1). O delineamento para os experimentos foi em blocos casualizados (DBC) com cinco concentrações de Cu e quatro repetições. As plantas foram cultivadas em substrato de solo acondicionados em vasos de 8 dm3 e mantidas em casa-de-vegetação por 90 dias. Foram avaliadas medidas biométricas, clorofila, enzimas antioxidantes e o teor de Cu nos tecidos. O Cu não influenciou no crescimento vegetativo das espécies estudadas. O teor de clorofila "a" foi reduzido com o aumento do Cu no solo. H. courbaril apresentou 56 a 92% do Cu retido nas raízes, ocorrendo o mesmo comportamento para P. dubium (77-91%) e M. peruiferum (19-64%). Nas três espécies em estudo houve bioacumulação do Cu nas raízes, possivelmente como estratégia de tolerância ao metal, preservando os tecidos mais ativos e a maquinaria fotossintética. A translocação do Cu das raízes para a parte aérea foi muito restrita em todas as espécies. Este comportamento associado com o aumento da atividade de algumas enzimas do sistema antioxidante nas plantas pode indicar o potencial fitorremediador das espécies estudadas.

ABSTRACT Copper (Cu) is an essential micronutrient for plants. However, when in excess, it becomes phytotoxic. In this context, the objective of this study was to evaluate the growth and physiological responses of tree species exposed to different copper concentrations in the soil. Three experiments were carried out, one for each forest species under study: Myroxylon peruiferum ("Óleo Bálsamo"), Hymenaea courbaril ("Jatobá") and Peltophorum dubium ("Canafístula"), with the same doses of copper (0, 50, 100, 200 and 400 mg kg-1). The experimental design was in randomized blocks (DBC), with five copper concentrations and four replicates. The plants were grown on soil substrate packed in 8-dm3 pots and kept in a greenhouse for 90 days. Biometric measurements, chlorophyll, antioxidant enzymes and copper content in tissues were evaluated. Copper did not influence the vegetative growth of the species studied. The content of chlorophyll "a" was reduced with increasing copper concentrations in the soil. H. courbaril had 56 to 92% copper retained in the roots, and the same behavior was observed for P. dubium (77-91%) and M. peruiferum (19-64%). In the three species studied, there was copper bioaccumulation, mainly in the roots, possibly as a metal tolerance strategy, preserving the most active tissues and the photosynthetic machinery. Cu translocation from roots to shoot was very restricted in all species. This behavior, associated with the increase in the activity of some antioxidant enzymes in plants, may indicate the phytoremediation potential of the studied species.

RESUMO Este estudo objetivou caracterizar aspectos relacionados à dispersão de propágulos de Myrceugenia euosma (O. Berg) D. Legrand (Myrtaceae) em um fragmento de Floresta Ombrófila Mista em Urupema, SC. Para isso, foram avaliados 29 indivíduos reprodutivos quanto à frequência de visitantes, chuva de propágulos, remoção e caracterização de frutos. Registraram-se 140 visitas de pássaros, sem ocorrência de período preferencial. As espécies com maior frequência de visita e maior consumo de frutos foram Zonotrichia capensis (tico-tico) e Stephanophorus diadematus (cabeça-de-velho), consideradas potenciais dispersoras. A frequência de coletores contendo propágulos de M. euosma diminuiu com o aumento da distância, apresentando comportamento distinto em função do tipo de propágulo avaliado. Também foram verificadas sementes intactas junto às fezes das aves nos coletores. A taxa de remoção de frutos depositados no chão foi de 22%, isso demonstra a relevância desse tema no processo de dispersão das espécies, merecendo atenção na realização de estudos futuros.

ABSTRACT This study aimed to characterize aspects related to propagules dispersion of Myrceugenia euosma (Myrtaceae) in a fragment of Mixed Ombrophillous Forest, Urupema, SC. For this, twenty-nine seed tree were evaluated for focal observation of visitors, propagules rain, removal and characterization of fruits. We recorded 140 visits of birds, occurring without preferential visit period. The species with higher visiting frequency and consumption of fruits were Zonotrichia capensis (Rufous-collared Sparrow) and Stephanophorus diadematus (Diademed Tanager), considered as potential dispersers. The frequency of collectors containing M. euosma propagules decreased with increased distance, presenting distinct behavior depending the type of propagule evaluated. We also found intact seeds in bird feces inside the collectors. The removal rate of fruits deposited on the ground was 22%, demonstrating that this is an important topic on the dispersal process and deserves attention in future studies.

RESUMO: Objetivou-se caracterizar a estrutura demográfica e o padrão espacial de Campomanesia xanthocarpa (Mart.) O. Berg, Myrcianthes gigantea (D. Legrand) D. Legrande Myrciaria delicatula (DC.) O. Berg, bem como, verificara influência de variáveis ambientais sobre essas populações. Em um hectare de Floresta Atlântica, todos os indivíduos das três populações foram contados e mensurados quanto à altura e diâmetro. A estrutura demográfica foi avaliada após classificação de tamanho dos indivíduos, o padrão espacial pelo Índice de Morisita Padronizado. Campomanesia xanthocarpa e M. delicatula apresentaram distribuição de frequência dos indivíduos em classes de tamanho em J invertido, já a espécie M. gigantea não seguiu o mesmo comportamento. O padrão espacial das populações de C. xanthocarpa e M. delicatula foi, predominantemente, agregado e, para M. gigantea, o padrão foi aleatório. Verifica-se que as populações de Myrtaceae possuem respostas diferenciadas quanto à estrutura e distribuição espacial em sítios com os mesmos filtros ambientais.

ABSTRACT: The aim of this study was to characterize the demographic structure and spatial pattern of Campomanesia xanthocarpa (Mart.) O. Berg, Myrcianthes gigantea (D. Legrand) D. Legrand and Myrciaria delicatula (DC.) O. Berg. Within one hectare of Ombrophilous Mixed Forest, all the three populations' individuals were counted and measured with regard to their height and diameter. From the collected data, the assessment of the demographic structure was realized after the individual's size classification. Spatial pattern was determined by applying the Standardized Morisita's Index. C. xanthocarpa and M. delicatula showed an inverted-J frequency distribution in the individuals size classes, which differed from M. gigantea that did not follow the same pattern. The spatial pattern of C. xanthocarpa and M. delicatula populations was found mainly to be aggregated; whereas, M. gigantea showed spatial randomness. The three Myrtaceae populations responded differently with regard to structure and spatial distribution in sites with the same environmental filters.

Resumo Objetivo: Investigar os determinantes de sobrecarga familiar numa amostra de pacientes com esquizofrenia e seus cuidadores. Métodos: Trinta e um pacientes com esquizofrenia e seus principais cuidadores participaram do estudo. Variáveis sociodemográficas foram analisadas por meio de uma entrevista semiestruturada, e sintomas positivos e negativos foram quantificados através da Positive and Negative Syndrome Scale (PANSS). O desempenho cognitivo foi mensurado pela Schizophrenia Cognition Rating Scale (SCoRS). A Escala de Avaliação da Sobrecarga dos Familiares (FBIS) avaliou os níveis de sobrecarga entre os cuidadores. As interações entre as variáveis foram verificadas por meio do coeficiente de correlação de Pearson e de análise de regressão linear. Resultados: Os escores objetivos e subjetivos da FBIS foram 1,9 [desvio padrão (DP) 0,5] e 2,4 (DP 0,6), respectivamente. Sobrecarga objetiva se correlacionou positivamente com sintomas positivos e negativos, e com prejuízos cognitivos. A sobrecarga subjetiva se correlacionou positivamente com sintomas positivos, e negativamente com a idade de início da doença. Os sintomas positivos e negativos e os prejuízos cognitivos contribuíram com 47,6% da variância da sobrecarga objetiva, sendo que sintomas negativos foram responsáveis independentemente por 30,3%. A idade de início da doença, os pais na posição de cuidadores e os sintomas positivos contribuíram com 28% da variância da sobrecarga subjetiva, sendo que a idade de início da doença contribuiu independentemente com 20,3%. Conclusões: Variáveis sociodemográficas e clínicas dos pacientes são importantes determinantes de sobrecarga familiar na esquizofrenia. A sobrecarga objetiva pode ser predita por sintomas, especialmente os negativos. A sobrecarga subjetiva pode ser predita por sintomas e características sociodemográficas, particularmente a idade de início da doença.

Abstract Objectives: To investigate the determinants of family burden in a sample of patients with schizophrenia and their caregivers. Methods: Thirty-one stable patients with schizophrenia and their main caregivers were recruited. Sociodemographic variables were assessed in a semi-structured interview, and positive and negative symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Cognitive performance was assessed with the Schizophrenia Cognition Rating Scale (SCoRS). Levels of burden on caregivers were assessed with the Family Burden Interview Schedule (FBIS). Interactions among variables were analyzed using Pearson correlations and linear regression analysis. Results: Objective and subjective FBIS scores were 1.9 (standard deviation [SD] = 0.5) and 2.4 (SD = 0.6) respectively. Objective burden correlated positively with positive and negative symptoms, and cognitive impairment. Subjective burden correlated positively with positive symptoms and negatively with mean age of disease onset. Positive, negative and cognitive symptoms accounted for 47.6% of the variance of objective burden, with negative symptoms accounting independently for 30.3%. Age of onset, parents as caregivers and positive symptoms accounted for 28% of the variance of subjective burden, with age of onset independently explaining 20.3%. Conclusion: Patients' clinical and sociodemographic variables are important determinants of family burden in schizophrenia. Objective burden is predicted by symptoms, particularly negative ones. Subjective burden is predicted by symptoms and sociodemographic variables, particularly age of disease onset.

RESUMO Materiais orgânicos submetidos a um processo de digestão anaeróbia, por meio de biodigestor, produzem biofertilizante que pode ser utilizado na agricultura como fonte de nutrientes. O objetivo do presente trabalho foi avaliar o efeito de biofertilizante de dejeto líquido de suínos em atributos químicos do solo, na produtividade e no teor de nutrientes nas folhas e nos grãos de milho. O experimento foi realizado em condições de campo, de novembro de 2012 a abril de 2013. Empregou-se delineamento experimental em blocos ao acaso, com sete tratamentos em quatro repetições. Os tratamentos foram constituídos por doses de biofertilizante de dejeto líquido de suínos, 0; 40; 80; 120; 160; 200 e 240 m3 ha-1, aplicadas na superfície do solo, de uma única vez, no estádio fenológico V2 do milho. Aos 33 dias após a aplicação do biofertilizante foram coletadas, em cada parcela, amostras de solo. A colheita foi realizada aos 129 dias após a semeadura do milho. A aplicação de até 240 m3 ha-1 de biofertilizante de dejeto líquido de suínos, em solo com boas condições de fertilidade, não alterou os atributos químicos do solo e não influenciou na produtividade de milho. O uso de biofertilizante de dejeto líquido de suínos não afetou os teores de nutrientes no tecido foliar nem nos grãos de milho.

ABSTRACT Organic materials subjected to a process of anaerobic digestion in a digester produce biofertilizer that can be used in agriculture as nutrient source. The objective of this study was to evaluate the effect of pig slurry biofertilizer on soil chemical properties and on corn yield and nutrient concentrations in leaves and kernels. The experiment was conducted in the field from November 2012 to April 2013, and was arranged in a randomized block design with seven treatments and four replicates. The treatments consisted of doses of pig slurry biofertilizer (0; 40; 80; 120; 160; 200 and 240 m3 ha-1), applied to the soil surface in a single application, at stage V2 of corn plants. Thirty-three days after biofertilization, soil samples were collected in each plot. Corn was harvested 129 days after sowing. Doses up to 240 m3 ha-1 of pig slurry biofertilizer applied to soil with good fertility did not influence soil chemical properties and corn yield. The use of pig slurry biofertilizer had no detectable effect on nutrient concentrations in corn leaves and kernels.

Abstract: En | Text: En | PDF: En

Historically, measures of everyday functioning have focused exclusively on real-world performance. Despite the unquestionable value of “real-world functioning”, it has become clear that instruments for its assessment might not be as accurate as desirable. Functional capacity is a domain of everyday functioning that can be assessed through performance-based measures. In the last decade, functional capacity has become a cornerstone for the assessment of everyday functioning, since, alongside measures of real-world functioning, it provides a much more comprehensive picture of functional outcomes than any measurement alone. Functional capacity is more stable and less vulnerable to influence from environmental factors than other domains, and its correlation with cognitive functions has encouraged the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) project to suggest that a performance-based measure of functional capacity be included as a co-primary assessment of cognition in clinical trials. Functional capacity assessment instruments may be also useful in the evaluation of remission in schizophrenia. Validation of these instruments in different countries is desirable, and should always include cross-cultural adaptation; within large countries, adjustment for regional variations should be considered.
