Epileptic syndromes are highly prevalent neurological conditions and can often be disabling. In order to find an alternative for treatment, this study evaluated anticonvulsant effects of carvacryl acetate (CA), a derivative of monoterpene carvacrol, after seizures induced by pilocarpine (P400), picrotoxin (PIC) or pentylenetetrazol (PTZ). We also analyzed the CA effects on Na+, K+-ATPase and δ-aminolevulinic acid dehydratase (δ-ALA-D) activities in hippocampus mice after seizures induced by P400, PIC or PTZ. In addition, glutamate, δ-aminobutyric acid (GABA), glutamine and aspartate levels in mice hippocampus treated with CA after seizures induced by P400, PIC or PTZ were also measured. CA produced anticonvulsant effects against seizures induced by P400, PIC or PTZ, and its effects were reversed by flumazenil, suggesting that action mechanism can be mediated by GABAergic system. CA increased GABA levels, but did not alter glutamate and aspartate concentrations in mice hippocampus after seizures induced by P400, PIC or PTZ when compared with seizures induced by P400, PIC or PTZ (p<0.05), respectively, as well as decreased glutamine content in mice hippocampus after seizures induced by PIC when compared with seizures induced by PIC (p<0.05). In addition, CA also increased Na+, K+-ATPase and δ-aminolevulinic acid dehydratase activities after seizures induced by P400, PIC or PTZ when compared with seizures induced by P400, PIC or PTZ (p<0.05), respectively. This study demonstrated that CA could be a future therapeutic option for treatment of epilepsy, with a multifactorial brain action mechanism.
This study aimed to evaluate the quality of honey from Apis mellifera L. obtained in Piauí, Brazil. The completely randomized design (CRD) was used in the experiments. Two treatments of honey were prepared: one from beekeepers that use Extraction Units for Bee Products (EUBP) with Best practices for beekeeping (T1), and another one from those which use EUBP without the best practices (T2). Parameters analyzed were: moisture, water activity (aw), pH, acidity, color, detection of Salmonella spp., MPN.g-1 of coliforms at 35°C and at 45°C, counting of coagulase-positive Staphylococcus, standard counting of mesophilic heterotrophic bacteria and detection of yeast and filamentous fungi. The counting of mesophilic heterotrophic bacteria and yeast and filamentous fungi showed abnormalities (p<0.05) in the counting performed in log 10 .g-1 with samples of T1 and T2, respectively. There were presence of fungi of various genus and species, especially Aspergillus spp. and Penicillium spp. The quality of honey from Apis mellifera bees from Piauí, Brazil, was satisfactory regarding parameters of moisture, aw, pH and HMF. Neither Salmonella spp., nor coliforms, nor coagulase-positive Staphylococcus were found. The presence of filamentous fungi in the samples reinforces the need for quality control of honey from Piauí, Brazil.
Objetivou-se elaborar um doce com diferentes concentrações de massa do pedúnculo do caju e soro de leite, e verificar sua microbiologia por seis meses e a sua aceitabilidade sensorial. Foram desenvolvidas quatro formulações com diferentes percentuais de massa e soro de leite. Realizou-se teste de análise de variância, one-way ANOVA, post hoc test Tukey e transferiu-se os dados para o programa estatístico Graph Pad Prism 5.01 e SPSS 19.0 para análise de regressão. Foram realizadas análises microbiológicas durante 180 dias de armazenamento e análise sensorial. Não foi verificado contagem significativa dos micro-organismos pesquisados. Constatou-se boa aceitabilidade das formulações F1 (0%) e F2 (10%) com índices superiores à 70% para todos os atributos investigados, e intenção de compra de 74,00% e 79,40%, respectivamente. Os atributos obtiveram escores entre 6,14 e 7,34, sendo a menor atribuída à textura da formulação com 30%, e a maior, para a aceitação global da formulação com 10% de massa do pedúnculo do caju. Na análise de regressão linear não foi observada significância estatística para todos os parâmetros. Não houve ocorrência significativa dos microrganismos pesquisados. O doce apresenta maiores porcentagens e índices de aceitabilidade nas formulações com 0% e 10% da massa do pedúnculo do caju.
Objetivo: Investigar fatores predisponentes à insegurança alimentar em famílias beneficiárias de programa de transferência de renda. Método: Estudo transversal, descritivo, realizado com 224 famílias de um município piauiense, no período de março a junho de 2012. Os dados foram coletados por meio de um questionário estruturado, processados no Statistical Package for the Social Sciences e submetidos a análise estatística. Resultados: Das famílias pesquisadas 88,4% apresentaram insegurança alimentar. Foi observada significância estatística entre as variáveis localidades em que residem, tipos de moradias, gastos da família com alimentação e número de cômodos da casa (p≤0,05) com a insegurança alimentar. Conclusão: Assim, faz-se necessário políticas de segurança alimentar e nutricional que tenha como objetivo final a redução das desigualdades com medidas imediatas e eficazes para minimizar a convivência com a fome e prevenir a ocorrência deste agravo na comunidade.
