Boletim do Museu Paraense Emílio Goeldi : Ciências Naturais , 2006,
Abstract: The pollination ecology and breeding system of the shrubby species Centrosema pubescens Benth. Was studied in the on tropical forest of Acre. The anthesis is diurnal and the flowers were visited by bees (9 spp.) and wasps (5 spp.) basicaly. The guild of pollination is composed by bees of the genus Xylocopa, Bombus, Euglossa, Exarete, Mesoplia, Megachile and Trigona and by wasps of the of the families Polybinae and Scoliidae. One species of bee and of moth behave as nectar thieves. The species is self-compatible but ptoduce fruit via selfing and outcrossing. Pollen vectors are not required for fruit set because the flower shows secondary presentation of pollen's grain.

Abstract: Coffee brings many health benefits due to its chemical constituents. Based on this information, it is essential to know the main chemical compounds from coffee granules; the intermolecular interaction among the coffees compounds and the molecular components homogeneity. In this study six types of roasted commercial coffee were evaluated by solid state nuclear magnetic resonance (NMR), employing carbon-13 (13C) and hydrogen (1H) nucleus. Carbon-13 was analyzed applying high field NMR techniques, such as: magic angle spinning (MAS); magic angle spinning with cross-polariza- tion (CPMAS) and magic angle spinning with cross-polarization and dipolar dephasing (CPMASDD). The hydrogen was evaluated via relaxation times. Proton spin-lattice relaxation time in the rotating frame was deter-mined through the carbon-13 decay, during the variable contact-time experiment, using high field NMR. Proton spin-lattice relaxation time was determined through the inversion-recovery pulse sequence, using low field NMR. Considering all NMR results, it was concluded that the major coffee compounds are: a) triacilglycerides, which constitute the mobile region in the granule coffee and b) Carbohydrates such as: polysaccharides and fibers that belong to the rigid domain. These constituents belong to different molecular mobility domain, although they have strong intermolecular interactions due to the granule organization.

Abstract: objective: to analyze and deepen understanding about what pregnant women who are tobacco/nicotine dependents think and experience about these conditions. method: qualitative research using narratives obtained from a purposive sample of pregnant or puerperal smokers or who discontinued tobacco use during pregnancy. the narratives' statements of fourteen patients from family health units of a brazilian municipality were analyzed. results: four categories were formulated: the desire to stop using, contrasting with the unidentified role professionals and services; questions about the health of the mother and her child; sociocultural and family issues and, finally, what is termed here as "spontaneous epidemiology". social representations that were observed show discrepancies and homologies with the ways in which health sciences deal with smoking during pregnancy. the participants considered not to exist a therapeutic culture for nicotine dependence in primary health care services they frequent, and they seemed to be distressed about this issue as well with the socio-cultural and family conflicts they face. a peculiar understanding about the health risks came to light. conclusion: although the results are not generalizable, the tensions observed strongly suggest the need for further adaptation of the primary health care to the needs of pregnant smokers.

Abstract: objective: this review aims to verify the scientific evidences for the inclusion of culture bound syndromes in the international classification of diseases towards its 11th edition based on studies from latin american and caribbean countries. method: studies were identified in medline, lilacs and embase databases for the period between 1992 and 2008, and then classified according to the type of study, to the mental disorder, country and number of publications per year. results: 163 studies were selected and classified: 33 in medllne, 90 in embase e 40 in lilacs. the percentage of culture bound-syndrome corresponded to 9% in medline, 12% in embase e 2.5% in lilacs. among fifteen studies on cultural bound syndromes, two were about "nervios and ataque de nervios", two about "susto", four about the relationship between religion beliefs, witchery, trance and mental disorders, one with a proposal for new diagnostic category, three about theoretic issues and three about the pathoplasty of mental disorders. conclusion: the scarcity of studies on culture bound syndromes might be due to the indexation problems hindering the screening of studies; lack of interest on publishing such studies in indexed journals (publication bias) and due to difficulty to access them. there is no robust evidence identified among cross-cultural studies to recommend changes for international classification of diseases-11th edition.

A Formal Model for Performance and Energy Evaluation of Embedded Systems
Nogueira Bruno,Maciel Paulo,Tavares Eduardo,Andrade Ermeson
EURASIP Journal on Embedded Systems , 2011,
Abstract: Embedded systems designers need to verify their design choices to find the proper platform and software that satisfy a given set of requirements. In this context, it is essential to adopt formal-based techniques to evaluate the impact of design choices on system requirements. To be useful, such techniques must produce accurate results with minimal computation time. This paper proposes an approach based on Coloured Petri Nets for evaluating embedded systems performance and energy consumption. In particular, this work presents a method for specifying and evaluating the workload and the platform components, such as processors and shared or private memories. The method is applied to model single processor and multiprocessor platforms. Experimental results demonstrate an average accuracy of 96% in comparison with the respective measures assessed from the real hardware platform.

Abstract: Sickle cell disease (SCD) is a genetic disorder characterized by a chronic inflammatory process, and new biomarkers have been studied as promising molecules for understanding the inflammation in its pathophysiology. The hemolysis and the release of molecules associated to the hemoglobin (Hb) catabolism, such as free Hb, iron, and heme, generating a oxidant environment with production of reactive oxygen and nitrogen species. The immune system plays a very important role in the inflammation, with cells secreting pro-inflammatory cytokines and chemokines. There is also a nitric oxide (NO) resistance state, with an impaired NO bioactivity, leading to a vascular dys-function; activation of platelet, leukocytes, erythrocytes, and endothelial cells, with expression of adhesion molecules and its ligands, and several receptors, that altogether participate at inflammatory process. During inflammation, there is an increase of dendritic cells (DCs) expresse toll like receptors (TLR), but the role of DCs and TLR in SCD pathogenesis is unclear. Also, there are molecules contributing for enhance the endothelium dysfunction, such as homocysteine that has been associated with vascular complications in the pathology of other diseases and it may contribute to the vascular complications presented by SCD patients. Circulating microparticules (MPs) levels are augmented in several diseases and have been described in SCD, where cells membrane compounds are associated to cell’s thrombotic and coagulation state, such as tissue factor and phosphatidylserine (PS), which may contribute to endothelial dysfunction. The knowledge of all these biomarkers may contribute to new therapeutic approach discover, improveing SCD patient life quality.

Abstract: Sickle cell anemia (SCA) is a genetically inherited hemolytic disorder characterized by chronic inflammation. Cytokine expression affects the pivotal pathways that contribute to disease pathogenesis, but the mechanisms involved are not well understood. SCA is associated with a proinflammatory state, and an enhanced inflammatory response occurs during vasoocclusive crisis. The immune system thus plays an important role in this inflammatory condition, with several cell types secreting pro-inflammatory cytokines that contribute to the occurrence of common cyclical events in SCA patients, such as hemolysis, vascular occlusion and inflammation. Studies of these cytokines and chemokines in SCA patients have clarified the mechanisms that underlie this disease and highlighted the need for a better understanding of cytokine participation in SCA pathophysiology.
