Foram analisadas as manifestações neurológicas em 93 doentes com suspeita de intoxicação exógena. A detecção das substancias tóxicas foi realizada no sangue, urina e líquido cefalorraqueano. Verificou-se nítido predomínio do comprometimento do sistema nervoso central em relação ao periférico e aparente tropismo de herbicidas e organofosforados para o sistema nervoso central, comparando-se o comportamento dos metais pesados e organoclorados. São analisados os prováveis mecanismos de ação dessas substancias no sistema nervoso e são apresentados os sinais e/ou sintomas que foram observados.

A retrospective study of etiology, antimicrobial susceptibility profile and multiple drug resistance, and major epidemiological aspects were investigated in 616 cases of canine otitis. Staphylococcus beta hemolitic (26.27%), Malassezia pachydermatis (12.35%), and Pseudomonas aeruginosa (8.8%) were the most common microorganisms identified. The isolates were susceptible mainly to norfloxacin (89.62%), gentamicin (83.25%), and ofloxacin (80.16%). High occurrence of resistance of isolates was observed to neomicin (30.84%) and cephalexin (27.63%). Multiple drug resistance to three or more and five or more of antimicrobials tested was observed in 34.9% and 15.5% of isolates, respectively. The cases of canine otitis occurred predominantly in first years of age, in mixed breeds animals, at autumn season. The presence of itch, bad smell, and secretion in ear conduct were the major signs observed at clinical examination.

Background: The AIN-93 diet was proposed by the American Institute of Nutrition with the objective of standardising studies in experimental nutrition. Our objective was to analyze the effects of AIN-93 diet after myocardial infarction in rats.Methods: Post weaning, the animals were divided into two groups: control (C, n=62), fed the standard diet of our laboratory (Labina); AIN-93 Group (n=70), fed the AIN-93 diet. Achieving 250 g, the animals were subjected to myocardial infarction.Results: Early mortality was increased in AIN-93 animals, associated with lower serum levels of calcium, magnesium, potassium, sodium, and phosphorus. on the other hand, after 90 days, AIN-93 showed smaller normalized left ventricular dimensions. The caloric and carbohydrate intake was smaller, but the fat intake was higher in AIN-93 rats. AIN-93 group also showed increased levels of beta-hydroxyacylcoenzyme A dehydrogenase and citrate synthase. In addition, serum levels of insulin and cardiac levels of malondialdehyde, metalloproteinases-2 and -9, and TNF-alpha and IFN-gamma were decreased in the AIN-93 group.Conclusion: AIN-93 diet increased early mortality, while attenuated the chronic remodeling process after experimental coronary occlusion. Therefore, this diet has biological effects and should be use with attention in this model. (C) 2010 Elsevier B.V. All rights reserved.

The phase transitions that occur in the Cu-22.26 at.%Al-9.93 at.%Mn and Cu-22.49 at.%Al-10.01 at.%Mn-1.53 at.%Ag alloys after slow cooling were studied using differential scanning calorimetry at different heating rates, microhardness changes with temperature, magnetization changes with temperature, scanning electron microscopy and energy dispersion X-ray spectroscopy. The results indicated that the presence of Ag does not modify the transition sequence of Cu-Al-Mn alloy, introduces a new transition due to the (Ag-Cu)-rich precipitates dissolution at about 800 K, and changes the mechanism of DO 3 phase dissolution. This mechanistic change was analyzed and a sequence of phase transitions was proposed for the reaction. © 2013 Elsevier B.V.
