Abstract: the aim of this research was to evaluate the hepatic biochemical profile and the renal enzymatic activity of broiler chicken experimentally intoxicated with aflatoxin and supplemented with sodic montmorilonite on the diet. 528 cobb?s broiler chickens were used divided in 6 treatments (from 1st to the 42th day of life) as described: (t1) control: normal diet; (t2) diet with 5ppm of aflatoxin; (t3) diet with 0.25% sodic montmorilonite; (t4) diet with 5 ppm of aflatoxin + 0.25% sodic montmorilonite; (t5) diet with 0.5% sodic montmorilonite; (t6) diet with 5 ppm of aflatoxin + 0.5% sodic montmorilonite. the treatment t2 showed significantly decreased levels of uric acid, albumin, cholesterol, creatinine, triglycerides, globulins and total serum proteins and an increase of serum alanine aminotransferase (alt) activity. aspartate aminotransferase (ast) did not showed important differences among treatments. in treatments t3 and t5, there were no variations on the biochemical values, when compared to treatment t1. addition of 0.5% of montmorilonite in the diet (t6), presented better results on the increase of the adsorption of aflatoxin when compared to 0.25% sodic montmorilonite (t4). clearly, the results showed that high levels of aflatoxin in the diet (5ppm) causes important changes in the serum enzymatic activity of broiler chickens. also, it was demonstrated that using sodic montmorilonite may be used to avoid risks caused by food contaminated by aflatoxins.
Considera es historiográficas acerca da lógica dos estoicos
Cleverson Leite Bastos,Paulo Eduardo de Oliveira
Princípios : Revista de Filosofia , 2011,
Abstract: This study aims to examine some questions related to how the historiography evaluated the contribution offered by logical Stoic philosophers. It is, above all, two open positions in opposition: an initial analysis is essentially negative and derogatory, denying any value to elaborations stoic in logic; the other hand, there is a revaluation of the importance of logic in the history of the Stoic Philosophy, in general, and in the history of logic, specifically. The main reference here emphasized is the positive work of the logician Lukasiewicz. It is intended, therefore, provide subsidies for a reflection that extends the evaluation of the potential that Stoic logic offers to students of Philosophy and Logic.

Arquivos de Neuro-Psiquiatria , 2007, DOI: 10.1590/S0004-282X2007000500027
Abstract: osmotic demyelination syndrome (ods) may be precipitated by aggressive correction of a hypo or hyper-osmolar states. we describe the case of a 53-year-old woman that was started on fluoxetine 20 mg/day for depression and nine days later was found to have fluoxetine-induced syndrome of inappropriate secretion of antidiuretic hormone. after hyponatremia correction the mental status of the patient gradually improved, but subsequently she had intermittent difficulty in speaking, naming objects, memory deficits and psychomotor slowness. magnetic resonance revealed bilateral symmetric hyperintense lesions in the basal ganglia, temporal lobe and hippocampal formation compatible with ods. these symptoms gradually resolved and she was discharged home without any deficits. two months later, a new image showed lesion in pons and the other lesions had disappeared. fluoxetine therapy had never been related with a complication like that.

Revista Paranaense de Desenvolvimento , 2006,
Abstract: A rodovia PRT-163 passou a ligar os municípios paranaenses de Toledo e Marechal Candido Rondon, fun o até ent o desempenhada pela PR-239, onde se localizam a sede do município de Quatro Pontes e os distritos de Novo Sarandi e Vila Nova, ligados à comarca de Toledo. Com o acabamento das obras da rodovia PRT-163, o trajeto entre Toledo e Marechal Candido Rondon foi encurtado em cerca de 17 quil metros. Por meio de levantamento de dados primários nos núcleos de Quatro Pontes, Novo Sarandi e Vila Nova, este artigo procura analisar se há ou n o a possibilidade de ocorrer algum impacto econ mico e social nesses centros em fun o da reorienta o de boa parte do fluxo de veículos da PR-239 para a PRT-163. Concluiu-se que as perdas financeiras, resultantes da nova orienta o do transito, ser o mínimas e compensadas pelos ganhos de qualidade de vida Nowadays, the PRT-163 highway connects Toledo municipality to Marechal Candido Rondon municipality (State of Paraná) which were formerly connected by PR-239, where the municipalities of Quatro Pontes, Novo Sarandi and Vila Nova are located; they are also connected to Toledo. After the end of PRT-163 highway works, the distance between Toledo and Marechal Candido Rondon was shortened by 17 km. Using primary data collected in Quatro Pontes, Novo Sarandi and Vila Nova, the present article tries to analyze whether or not there is the possibility of some economic and social impacts on these areas due to the redirectionong of part of vehicle flow from PR-239 to PRT-163. As a result we inferred that there will be minimum financial losses from this new traffic directioning, and besides that, such losses will be compensated by the gains in the quality of life of those municipalities

Ciência Florestal , 1999,
Abstract: Este trabalho teve como objetivo geral proceder a avalia o da seguran a no trabalho de operadores de motosserra no corte de eucalipto em áreas montanhosas. A coleta de dados foi efetuada em uma empresa florestal na regi o do Vale do Rio Doce, em Minas Gerais, nos Municípios de Marliéria e Córrego Novo, no período de outubro de 1995 a fevereiro de 1996. A área estudada está inserida na regi o bioclimática número 5 do Estado de Minas Gerais cujo clima é classificado como subtropical úmido-subúmido, com temperatura média anual variando de 20 a 23 oC, precipita o média anual variando de 1.100 a 1.400 mm e altitude de 200 a 900 m, em relevo que varia de suave ondulado a montanhoso. Foram estudados os aspectos de seguran a no trabalho e acidentes de uma amostra de 29 operadores de motosserra, ou seja, 45,13 % do total de operadores de motosserra da Empresa, que atuam em regi es de relevo montanhoso. A produtividade individual variou de 7,98 a 13,08 m3/dia. A derrubada foi atividade na qual ocorreu o maior número de acidentes entre os operadores de motosserra. As partes do corpo mais atingidas foram os membros inferiores (pernas e pés) com 37,4% das ocorrências. A falta de aten o por parte do operador foi apontada como a principal causa de acidentes no corte florestal, por 35,0% dos operadores de motosserra. As causas humanas, somadas, representaram a opini o de 72,5% dos operadores de motosserra.

CERNE , 2002,
Abstract: This research was developed in eucalyptus plantations, in Marliéria and Córrego Novo, inthe state of Minas Gerais, Brazil, with the objective of multivariated analysis applying in the study ofhuman factors related to chainsaw cutting, clustering the chainsaw operators, considering theindividual productivity and the envolved human factors. The cluster analysis classified the chainsawoperators in four groups. Thirteen factors were important in clustering the chainsaw operators, among the20 factors analised. The productivity on the job was a very important factor in the chainsaw operatorsclustering, because the three most productive chainsaw operators have formed one group and the lessone has formed another group.
