Se evaluó una nueva metodología para detectar y cuantificar la formación de acrilamida en las etapas de producción de la panela. Los datos de esta investigación contribuyen al control de calidad de la panela, particularmente en la evaluación del riesgo químico asociado a este producto de uso popular, en beneficio primordial del sector agroalimentario y de la calidad. La técnica de análisis empleada fue la cromatografía líquida de alta eficiencia en fase reversa, y el método de cuantificación empleado fue el estándar externo, para lo cual se construyó una curva de calibración. Se halló que en el jugo de caña no se forma acrilamida, pero a medida que aumenta el tiempo y la temperatura (reacción de Maillard) se evidencia su presencia, encontrándose en el producto final 2.0 mg/kg; se pudo, en consecuencia, establecer la efectividad de la cuantificación por este método analítico; para la verificación y confirmación del contenido de acrilamida, información útil para evaluar la autenticidad del producto final.

A new method for the detection and quantification of acrylamide formation in the production stages of sugar cane was evaluated. This research provides data to help the food industry, particularly in quality control of sugar cane, for chemical risk evaluation associated with this popular product and often used for primary benefit of the quality and food industry. The technique employed was high efficiency liquid chromatography in reverse phase, the quantification method employed was the external standard, for which a calibration curve was constructed. Getting in cane juice, acrylamide formation does not occur, but with increasing time and temperature (Maillard reaction) its presence is evident; found in the final product 2.0 mg/kg, so it can establish the effectiveness of quantification for this analytical method, for verification and confirmation of acrylamide, also contribute useful for evaluation of the authenticity of the final product information.

Foi determinada a prevalência de Ehrlichiose canina entre animais atendidos no Complexo Hospitalário Veterinário do Corozal da Faculdade de Medicina Veterinária da Universidade de Panamá. O levantamento foi realizado de forma retrospectiva com dados obtidos no período de janeiro de 2004 a dezembro de 2009. Para o trabalho, foram utilizados os registros dos casos clínicos de ehrlichiose canina, confirmados através de esfregaço sanguíneo, a raça e os aspectos demográficos (idade, sexo e local de origem) de cada animal. Os resultados revelaram que 10,12% dos animais atendidos (n = 1.452) mostraram-se positivos para o problema no período em análise. Esses animais eram de ambos os sexos com idade media de aproximadamente 3,6 anos. A prevalência mensal registrada foi de 9,98%, com taxa de infecção significativamente superior em 2008 (14,83%). O número de casos positivos foi significativamente superior nos meses de março, maio e setembro e menor no mês de fevereiro, destacando-se haver densidade de casos igual ou superior à média de maio a outubro. A raça e o local de origem dos animais foram identificados como fatores de risco.

The aim of this study was to determine the prevalence of canine Ehrlichiosis among animals treated at the Corozal Veterinary Hospital of the Faculty of Veterinary Medicine, University of Panama, Brazil. The survey was conducted retrospectively with data obtained from January 2004 to December 2009, based on the records of clinical cases of canine ehrlichiosis, confirmed with blood smear, race and demographics data (age, sex and place of origin) of each animal. The results revealed that 10.12% of the treated animals (n = 1452) were positive in the period under review. These animals were of both sexes with a mean age of approximately 3.6 years. The monthly prevalence recorded was 9.98%, with a significantly higher infection rate in 2008 (14.83%). The positive cases were significantly higher in the months of March, May and September and lowest in February, with a noteworthy density of cases equal to or higher than the average from May to October. Breed and place of origin of the animals were identified as risk factors.
