Radiopacity Of Glass-ionomer/composite Resin Hybrid Materials.

This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium stepwedge. All hybrid materials were more radiopaque, except for one resin-modified glass-ionomer cement, than both the tooth structure and conventional glass-ionomer cement.122858

ERP correlates of error processing during performance on the HalsteadCategory Test

The Halstead Category Test (HCT) is a neuropsychological test that measures a person's ability to formulate and apply abstract principles. Performance must be adjusted based on feedback after each trial and errors are common until the underlying rules are discovered. Event-related potential (ERP) studies associated with the HCT are lacking. This paper demonstrates the use of amethodology inspired on Singular SpectrumAnalysis (SSA) applied to EEG signals, to remove high amplitude ocular andmovement artifacts during performance on the test. This filtering technique introduces no phase or latency distortions, with minimum loss of relevant EEG information. Importantly, the test was applied in its original clinical format, without introducing adaptations to ERP recordings. After signal treatment, the feedback-related negativity (FRN) wave, which is related to error-processing, was identified. This component peaked around 250ms, after feedback, in fronto-central electrodes. As expected, errors elicited more negative amplitudes than correct responses. Results are discussed in terms of the increased clinical potential that coupling ERP informationwith behavioral performance data can bring to the specificity of theHCT in diagnosing different types of impairment in frontal brain function.info:eu-repo/semantics/publishedVersio

Failure regime in (1+1) dimensions in fibrous materials

In this paper, we introduce a model for fracture in fibrous materials that takes into account the rupture height of the fibers, in contrast with previous models. Thus, we obtain the profile of the fracture and calculate its roughness, defined as the variance around the mean height. We investigate the relationship between the fracture roughness and the fracture toughness.Comment: 4 pages, 4 figures.eps, Revte

Obesidade e a prevalência da síndrome metabólica, um estudo em crianças e adolescentes madeirenses

A obesidade atinge actualmente proporções epidemiológicas, tendo-se vindo a registar um incremento alarmante na população pediátrica. Diversos estudos têm mostrado a existência de um forte vínculo entre a obesidade e a prevalência da Síndrome Metabólica (SM). O presente estudo tem como objectivo central determinar a contribuição do excesso de peso e da obesidade na prevalência da SM em crianças e adolescentes

Corpo, maturação biológica e actividade física: um olhar interactivo em crianças e jovens madeirenses

Cada vez mais a sociedade moderna é olhada através da sua condição física, enquanto factor de bem-estar, saúde, qualidade de vida e longevidade dos seus membros. Os indicadores demográficos actuais da população madeirense apontam no sentido de uma considerável componente juvenil, adolescente e jovem. No entanto, a evolução demográfica prevista, decorrente de um acentuado decréscimo da natalidade, leva a prever um comportamento diverso da pirâmide de idades, assumindo particular ênfase as questões relacionadas com o estudo e a investigação do corpo, a procura de padrões, a descrição normativa, a interpretação das mudanças e o espaço morfológico externo, que se vem enquadrar no território de investigação reservado à somatotipologia

Analysis of the genetic variability of peach palm (Bactris gasipaes) in the Yurimáguas region, Peru, using molecular RAPD markers

Molecular markers were used to verify the existence of one or more primitive peach palm landraces, including Pampa Hermosa, in the microregion near Yurimáguas, Peru. This region provides the highest amount of seeds for peach palm heart agribusinesses in Brazil. In this analysis, we used 120 peach palm plants (Bactris gasipaes var. gasipaes) from four river basins around Yurimáguas. We used six primers, generating 73 RAPD markers. The heterozygosity ranged from 0.29 to 0.31, with a mean of 0.32, and the percentage of polymorphism ranged from 80.8 to 86.6, with a mean of 90.4. The dendrogram, based on Jaccard Similarity, presented eight groups, but it did not present groups formed by the water basins. The average gene flow was high, ranging from 11.41 to 18.89, as expected for populations within a same landrace. The analysis of the genetic diversity in this set of plants showed a common genetic basis among the plants. Nei's Genetic Distances were low, varying between 0.012 and 0.027. This suggests that such populations are very similar to each other, and that there is only one landrace in the region. Therefore, we propose the existence of only one landrace in the Yurimáguas region and the name "Pampa Hermosa" should be adopted. © 2018 Cientifica. All rights reserved

Conservation implications of the mating system of the Pampa Hermosa landrace of peach palm analyzed with microsatellite markers

Peach palm (Bactris gasipaes) is cultivated by many indigenous and traditional communities from Amazonia to Central America for its edible fruits, and is currently important for its heart-of-palm. The objective of this study was to investigate the mating system of peach palm, as this is important for conservation and breeding. Eight microsatellite loci were used to genotype 24 open-pollinated progenies from three populations of the Pampa Hermosa landrace maintained in a progeny trial for genetic improvement. Both the multi-locus outcrossing rates (0.95 to 0.99) and the progeny level multi-locus outcrossing rates (0.9 to 1.0) were high, indicating that peach palm is predominantly allogamous. The outcrossing rates among relatives were significantly different from zero (0.101 to 0.202), providing evidence for considerable biparental inbreeding within populations, probably due to farmers planting seeds of a small number of open-pollinated progenies in the same plot. The correlations of paternity estimates were low (0.051 to 0.112), suggesting a large number of pollen sources (9 to 20) participating in pollination of individual fruit bunches. Effective population size estimates suggest that current germplasm collections are insufficient for long-term ex situ conservation. As with most underutilized crops, on farm conservation is the most important component of an integrated conservation strategy. © 2015, Sociedade Brasileira de Genética. Printed in Brazil

Emerging Enteropathogenic Escherichia coli Strains?

Escherichia coli strains of nonenteropathogenic serogroups carrying eae but lacking the enteropathogenic E. coli adherence factor plasmid and Shiga toxin DNA probe sequences were isolated from patients (children, adults, and AIDS patients) with and without diarrhea in Brazil. Although diverse in phenotype and genotype, some strains are potentially diarrheagenic
