25. A COMPARISON OF NONLINEAR MODELS FOR DESCRIBING WEIGHT-AGE DATA IN ANGLO-NUBIAN DOES
RESUMO Objetivou-se avaliar a idade da pesagem e a qualidade do ajuste de modelos não lineares a dados longitudinais para descrever o padrão de crescimento de fêmeas Anglonubiana. Pesos de 104 animais do nascimento até 60 meses de idade, foram agrupados em 10 classes, com intervalos de seis meses. Em cada classe estimou-se parâmetros A, B e K com modelo

26. Evaluation of Bayesian models for analysis of crude protein requirement for pigs of Brazilian Piau breed
ABSTRACT: We evaluated the inclusion of information on genetic relationship into the analysis of crude protein requirement in diets for pigs of Brazilian Piau breed, using Bayesian inference. The animals were assigned to treatments in a completely randomized design in factorial scheme 4 × 2 (crude protein levels × sex) with 12 repetitions per treatment. Th

27. Composition and ecology of a snake assemblage in an upland forest from Central Amazonia
Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Exp

28. Food web and ecological models used to assess aquatic ecosystems submitted to aquaculture activities
RESUMO: Ecossistemas aquáticos continentais desempenham papel fundamental no desenvolvimento econômico e social, entretanto, são vulneráveis à degradação ambiental devido às diversas pressões a que estão submetidos. Entre as principais atividades antrópicas a interferir nestes ambientes, podemos destacar a aquicultura. A modelagem matemática de

29. Frequency and factors associated with Theileria equi, Babesia caballi and Trypanosoma evansi in equids from Bahia (Northeast Brazil)
Resumo Este estudo teve como objetivos conhecer a frequência e os fatores associados à infecção por Babesia caballi, Theileria equi e Trypanosoma evansi em equinos naturalmente infectados do nordeste do Brasil. Amostras de sangue de 569 equídeos (528 equinos, 8 muares e 33 asininos) foram coletadas e testadas para a presença do DNA destes parasitos at

30. PRODUCTIVE RESPONSES FROM BROILER CHICKENS RAISED IN DIFFERENT COMMERCIAL PRODUCTION SYSTEMS - PART I: FUZZY MODELING
ABSTRACT Broiler chickens are classified as homoeothermic animals and require a production environment within well-defined thermal comfort intervals. Therefore, the development of algorithms (mathematical models) to control the environment that can be embedded in microcontrollers becomes necessary. Hence, this work aimed to develop a fuzzy model for predicti

31. Risk of exposure of farms and subsistence nurseries to contact with wild boar in southern Mato Grosso do Sul
RESUMO: Com o avanço da distribuição do javali no ambiente rural, seus impactos não se restringem somente a sanidade suidea, embora as exigências quanto ao monitoramento e controle da espécie sejam exigências previstas pela OIE, para o reconhecimento do status de zona livre de peste suína clássica. A construção de modelos ecológicos de favorabili

32. The Antinociceptive Effect of the Leaves and Flowers Ethanolic Extracts of Tabebuia aurea (Silva Manso) Benth & Hook. F. ex S. Moore
ABSTRACT In view of the traditional use of Tabebuia aurea for treating pain and inflammation, the antinociceptive pharmacological potential of T. aurea ethanolic extracts (TAEE) was investigated through in vivo experimental models. First, the MTT assay was conducted to determine the potential cytotoxicity of the TAEEs. Afterwards, the acetic acid-induced wri

33. Proposal for a New Histological Scoring System for Cartilage Repair
OBJECTIVE: This study aimed to develop a new histological scoring system for use in a partial-thickness cartilage repair animal model. Although previous papers have investigated the regeneration of articular cartilage, the good results achieved in small animals have not been replicated in large animal models or humans, possibly because of the frequent use o

34. Are there differences in the growth adaptation processes of growing and mature organism models of short bowel syndrome?
OBJECTIVES: The purpose of this study was to present an experimental model of short bowel syndrome (SBS) in weaning rats and to compare the adaptative mechanisms of the remaining bowel in weaning rats and adult animals by means of morphometric, histologic and molecular methods. METHODS: Twenty-four weaning rats were divided into 3 groups of 8 animals, one

35. Impact of autologous whole blood administration upon experimental mouse models of acute Trypanosoma cruzi infection
Abstract Background: Autologous whole blood (AWB) administration is described as alternative/complementary medical practice widely employed in medical and veterinary therapy against infections, chronic pathologies and neoplasias. Our aim is to investigate in vivo biological effect of AWB using healthy murine models under the course of Trypanosoma cruzi acut

36. Perspectives for cancer immunotherapy mediated by p19Arf plus interferon-beta gene transfer
While cancer immunotherapy has gained much deserved attention in recent years, many areas regarding the optimization of such modalities remain unexplored, including the development of novel approaches and the strategic combination of therapies that target multiple aspects of the cancer-immunity cycle. Our own work involves the use of gene transfer technology
