13. Papel da neurogênese nos efeitos promnésicos do ambiente enriquecido sobre a memória social
Social memory comprehends the information necessary to identify and recognize co-specifics. This kind of memory is essential in many forms of social interaction and is modulated by the environmental conditions. Previous studies from our laboratory showed that social isolation impairs the social memory persistence and that enriched environment (EE) prevents t

14. Environmental influences on antibody-enhanced dengue disease outcomes
Because an enriched environment (EE) enhances T-cell activity and T-lymphocytes contribute to immunopathogenesis during heterologous dengue virus (DENV) infections, we hypothesised that an EE increases dengue severity. To compare single serotype (SS) and antibody-enhanced disease (AED) infections regimens, serial intraperitoneal were performed with DENV3 (ge

15. Efeito benéfico do enriquecimento ambiental sobre o déficit de memória e a plasticidade celular hipocampal em ratos diabéticos tipo 1
O diabetes mellitus tipo 1 (DMT1) tem sido associado com complicações a longo prazo no sistema nervoso central, além dos efeitos periféricos comuns relacionados à doença, causando disfunções cognitivas no encéfalo. Por outro lado, o enriquecimento ambiental (EA) induz mecanismos de plasticidade dependentes da experiência, especialmente no hipocampo

16. Enriched environment contributes to recovery of visual acuity and increases perineuronal nets in monocular-deprived animals
The aim of the present study was to analyze the influence of enriched environment on the distribution of perineuronal nets (PNNs) using a stereogically based unbiased protocol and visual acuity in adult Swiss albino mice that underwent monocular deprivation during the critical period of postnatal development. Eight female Swiss albino mice were monocular dep

17. Avaliação de antimicrobianos como promotores de crescimento via mistura mineral para bovinos de corte em pastejo / Antimicrobial growth promoters in mineral mixtures for grazing beef cattle
Antimicrobials which modifies rumen fermentation can improve economical efficiency of beef cattle grazing systems and reduce its possible impacts on the environment. It was conducted a series of experiments with the objective of evaluating free-choice mineral mixtures as an antimicrobial delivery system for grazing animals. On experiment 1, at Piracicaba-SP,

18. Expressão de zif268 no cérebro do lagarto Tropidurus Hispidus após exploração de um ambiente enriquecido.
Neste trabalho, foram investigadas alterações comportamentais associadas ao aumento da expressão da proteína Zif268 em áreas telencefálicas do lagarto tropical Tropidurus hispidus correspondentes ao Hipocampo (HC) de mamíferos. Foram utilizados 13 animais machos do lagarto T. hispidus, coletados no campus da Escola Agrotécnica Federal do RN, sob a li

19. Metais pesados e micronutrientes no solo e em folhas de Brachiaria decumbens às margens de rodovias / Heavy metals and micronutrients in soil and in leaves of Brachiaria decumbens on the margins of highways
The generation of various wastes, has become alarming in light of their growing volume and their disposal to form inappropriate, especially in soil. One of the characteristics of such waste is the possibility of being contaminated by heavy metals. The Fuel obtained the refining of oil, widely used in automobiles, are usually enriched with toxic elements. The

20. Using semantics to enhance query reformulation in dynamic distributed environments
Query answering has been addressed as a key issue in dynamic distributed environments. An important step in this process is reformulating a query posed at a peer into a new query expressed in terms of a target peer, considering existing correspondences between them. Traditional approaches usually aim at reformulating queries by means of equivalence correspon

21. Molecular identification and serological profile of Leptospira spp. isolated of white-eared-opossum (Didelphis albiventris) in South of Brazil / Identificação molecular e perfil sorológico de Leptospira spp. isolada de gambás-de-orelha-branca (Didelphis albiventris) no sul do Brasil
Leptospirosis is a zoonotic disease that occurs all over the world, particularly in developing countries, caused by bacteria of the genus Leptospira. Several marsupial species are considered susceptible to infection caused by a wide variety of Leptospira serovars, acting as reservoirs. In this work were collected serum and urine samples of 33 White-eared opo

24. Application of vermicomposting for the biorremediation of contaminated soil by polycyclic aromatic hidrocarbons / Aplicação de vermicompostagem para a biorremediação de solos contaminados por hidrocarbonetos policíclicos aromáticos
One of the main environmental problems that we face today is the soil contamination due to storage fuel tanks leakages. Fuels are comprised of a variety of hydrocarbons, among them are the polycyclic aromatic hydrocarbons (PAHs). Those are classified by US-EPA and NIOSH as prioritary contaminants, due to their carcinogenic and mutagenic characteristics and t
