13. Avaliação funcional dos eosinófilos na anemia falciforme e o efeito do tratamento com hidroxiureia / Altered functional properties of eosinophils in sickle cell anemia and effects of hydroxyurea therapy
Sickle cell anemia is the homozygous state for hemoglobin S. Inflammation plays an important role in the vaso-occlusive process of the disease, where leukocytes, proinflammatory cytokines and adhesion molecules are increased in the peripheral blood of patients with sickle cell anemia. Leukocytosis is associated with morbidity and mortality in these patients.

14. Induction of cell migration and activation in mice by the freshwater sponge Drulia uruguayensis Bonetto & Ezcurra de Drago, 1968 (Porifera: Metaniidae)
Freshwater sponges are abundant in the Amazon region and they have been known to cause dermatitis (acute inflammation) since the beginning of the 20th century. To determine whether additional constituents, besides their body spicules, cause dermatological reactions in humans, an experimental study was developed and carried out using mice and Drulia uruguayen

15. Avaliação dos tipos de processamento na descontaminação e na degradação do polipropileno reciclado / Evaluation of types of processing in the decontamination and degradation of recycled polypropylene
Polypropylene is one of the most used polymers worldwide, especially by the disposable packaging industry, causing serious environmental problems. Despite the fact that recycling this polymer has become common in Brazil due to its growing market, there are still some restrictions regarding its use in direct-contact food packaging. Therefore, in order to eval

16. Evaluation of genetic damage induced by glyphosate isopropylamine salt using Tradescantia bioassays
Glyphosate is noted for being non-toxic in fishes, birds and mammals (including humans). Nevertheless, the degree of genotoxicity is seriously controversial. In this work, various concentrations of a glyphosate isopropylamine salt were tested using two methods of genotoxicity assaying, viz., the pink mutation assay with Tradescantia (4430) and the comet assa

17. Migração de agentes em sistemas multi-agentes abertos / Agent migration in open multi-agents systems
A Inteligência Artificial Distribuída traz uma série de novas perspectivas para a computação quando considera sistemas heterogêneos, adaptativos, evolutivos, continuamente em funcionamento e abertos. Estes sistemas, chamados de sociedades, apresentam tais características por permitirem que seus componentes, chamados de agentes, migrem entre sociedades

18. Feira de São Cristóvão: uma incursão sobre os estudos na área e a tentativa de aproximação à relação global-local / Feira de São Cristóvão: a raid on the studies in the area and the attempt to approach to the global-local relation ship
This paper proposes an approach to the studies on traditionally called Fair of São Cristóvão, taking into account the relationship between participants agents and dynamics space. The goal is to better understand the force that moves the actors in the direction of change the fair to the form the Centro Luiz Gonzaga de Tradições Nordestinas (CLGTN), and s

19. Efeito da endotelina sobre a expressão gênica das melanopsinas (Opn4x e Opn4m) e do receptor de endotelina, subtipo ETc, em melanóforo de Xenopus laevis / Effect of endothelin on the gene expression of melanopsins (Opn4x and Opn4m) and endothelin receptor subtype ETc in melanophores of Xenopus laevis
The biological clocks are critical for synchronizing the behavior of organisms to changes in photoperiod. All rhythmic changes are crucial to the survival of the species since they provide for internal adjustments to coincide with the phase of the cycle most favorable. Many of these biological rhythms are clearly associated with the light-dark cycle, of majo

20. Thymic microenvironmental alterations in different kind of thymus atrophy / Aterações no microambiente timico frente a diferentes agentes indutores de atrofia
Thymus is the primary lymphoid organ responsible for differentiation of Tlymphocytes. This process is dependent of thymic microenvironment integrity and coordinated migration of hematopoietic precursors by chemokines and extracellular matrix elements. However, the literature shows that deep alterations in thymus microenvironment with modifications in thymocy

21. Avaliação das propriedades de transporte de massa contendo adições minerais / Evaluation of the mass transport containing mineral admixtures
The durability of reinforced concrete structures is damaged by the degrading action of the penetration of substances in the form of gases, vapors and liquids through the pores and cracks. It is known that water both in its pure form or containing dissolved ions such as chloride, sulphate, carbon dioxide or oxygen ions, can compromise the durability of concre

22. DEVELOPMENT OF A CAPILLARY ELECTROPHORESIS SYSTEM WITH CONTACTLESS CONDUCTIVITY DETECTION (C4D) FOR THE SEPARATION OF INORGANIC IONS / DESENVOLVIMENTO DE EQUIPAMENTO DE ELETROFORESE CAPILAR COM DETECÇÃO POR CONDUTIVIDADE SEM CONTATO PARA A SEPARAÇÃO DE ÍONS INORGÂNICOS
This work describes the development and evaluation of a home-made capillary electrophoresis (CE) system based on the capacitively coupled contactless conductivity detection (C4D) for the application in capillary zone electrophoresis (CZE). The C4D detection is based on prototypes previously described in the literature. The equipment constructed has a hydrody

23. Novas Tiazolidinadionas 3, 5-Dissubstituidas: sÃntese, comprovaÃÃo estrutural e avaliaÃÃo da atividade antiinflamatÃria
To the thiazolidinic nucleus, due to their chemical reactivity, are atributed several biological activities, fact that directed our research in search of new biologically active agents. Recent studies have demonstrated the potential of thiazolidinics derivatives in inhibiting the inflammatory response, characterized by the release of various endogenous pro-i

The present work deals with the sprouting of a new laboring generation in Brazil contemporary and problematical its process of constitution in classroom relating determination and on-determination of the phenomenon. The new laboring generation in question appears in a context of change in the accumulation standard of the capital, that produces important tran
