Perfil microbiológico da carne de frangos abatidos artesanalmente e na indústria, comercializados na grande Recife-PE

Considerando o elevado consumo da carne de frango no contexto nacional e mais especificamente na cidade do Recife, onde o abate clandestino ainda é intenso, objetivou-se delinear o perfil microbiológico da carne de frango disponível no mercado, comparando-se os produtos advindos de abatedouro industrial e artesanal e verificar se os produtos atendiam às especificações dos padrões recomendados pela legislação. Determinou-se o Número Mais Provável (NMP) de coliformes totais e termotolerantes, bem como realizou-se a pesquisa de Salmonella spp. e Aeromonas spp., além da contagem de bactérias aeróbias mesófilas, psicrófilas e Staphylococcus spp.. Foram analisadas 24 amostras, sendo que 12 advindas do processamento de frigoríficos industriais, resfriadas e comercializadas. As outras 12 amostras foram provenientes de abatedouro artesanal e comercializadas sem refrigeração. Nos resultados obtidos, a contagem de Staphylococcus spp., a determinação do NMP de coliformes totais e termotolerantes apresentaram valores acima dos permitidos nas carcaças artesanais, enquanto que, as pesquisas de Salmonella spp. e Aeromonas spp. não apresentaram diferença significativa. Nas carcaças artesanais o número de bactérias mesófilas foi 2,6 vezes maior que nas industriais, enquanto que no número de psicrófilas/pisicotróficas não houve diferença significativa entre as amostras. Algumas amostras não estão dentro dos padrões recomendados pela legislação

Higher Education and the demands of inclusive education : the vision of the managers of the Federal University of Ouro Preto.

A crescente demanda no campo da educa??o inclusiva, que vem se tornando pauta na Educa??o Superior, tem, de alguma maneira, contribu?do para o repensar dessa etapa de forma??o. Faz-se necess?ria a tomada de posi??o das institui??es no sentido de diminuir as barreiras que dificultam o pleno exerc?cio do direito dos cidad?os que, agora, nela adentram. Para tanto, investigamos como os gestores da Universidade Federal de Ouro Preto (Ufop) concebem tr?s conceitos que entendemos fundamentais para a implementa??o de pol?ticas inclusivas, sendo eles: inclus?o, interculturalidade e inova??o pedag?gica. Por meio da aplica??o de question?rios, realizamos a coleta de dados nos diferentes n?veis de gest?o da universidade. Do total de 120 question?rios aplicados 38 foram respondidos. Foi poss?vel observar que os gestores possu?am um maior conhecimento sobre o tema da inclus?o, o que n?o se estendeu aos outros dois conceitos. Podemos considerar que as respostas apontam para a necessidade de construir um campo de estudos e debates acerca dos conceitos investigados, no intuito de promover a forma??o no ?mbito da institui??o e, assim, garantir que a educa??o inclusiva seja central nas a??es da Ufop.The growing demand in the field of inclusive education that has become a subject in Higher Education has contributed to the rethinking of this stage of education. It is necessary for higher education institutions to step up the barriers that hinder the full exercise of the right of citizens who are now studying it. In this research, we investigate how the managers of theFederal University of Ouro Preto (Ufop) understand three fundamental concepts for the implementation of inclusive policies: inclusion, interculturality and pedagogical innovation. Data collection was performed through the application of 120 questionnaires with 38 respondents. From the answers it was possible to observe that the managers had a greater knowledge on the theme of inclusion, unlike the other two concepts. We can consider that the answers reveal the need to build a field of studies and debates about the concepts investigated. This can contribute to promote training in universities and to ensure that inclusive education is central to Ufop?s actions

Activation of Type 1 Cannabinoid Receptor (CB1R) promotes neurogenesis in murine subventricular zone cell cultures

The endocannabinoid system has been implicated in the modulation of adult neurogenesis. Here, we describe the effect of type 1 cannabinoid receptor (CB1R) activation on self-renewal, proliferation and neuronal differentiation in mouse neonatal subventricular zone (SVZ) stem/progenitor cell cultures. Expression of CB1R was detected in SVZ-derived immature cells (Nestin-positive), neurons and astrocytes. Stimulation of the CB1R by (R)-(+)-Methanandamide (R-m-AEA) increased self-renewal of SVZ cells, as assessed by counting the number of secondary neurospheres and the number of Sox2+/+ cell pairs, an effect blocked by Notch pathway inhibition. Moreover, R-m-AEA treatment for 48 h, increased proliferation as assessed by BrdU incorporation assay, an effect mediated by activation of MAPK-ERK and AKT pathways. Surprisingly, stimulation of CB1R by R-m-AEA also promoted neuronal differentiation (without affecting glial differentiation), at 7 days, as shown by counting the number of NeuN-positive neurons in the cultures. Moreover, by monitoring intracellular calcium concentrations ([Ca2+](i)) in single cells following KCl and histamine stimuli, a method that allows the functional evaluation of neuronal differentiation, we observed an increase in neuronal-like cells. This proneurogenic effect was blocked when SVZ cells were co-incubated with R-m-AEA and the CB1R antagonist AM 251, for 7 days, thus indicating that this effect involves CB1R activation. In accordance with an effect on neuronal differentiation and maturation, R-m-AEA also increased neurite growth, as evaluated by quantifying and measuring the number of MAP2-positive processes. Taken together, these results demonstrate that CB1R activation induces proliferation, self-renewal and neuronal differentiation from mouse neonatal SVZ cell cultures.Fundacao para a Ciencia e a Tecnologia - Portugal [POCTI/SAU-NEU/68465/2006, PTDC/SAU-NEU/104415/2008, PTDC/SAU-NEU/101783/2008, POCTI/SAU-NEU/110838/2009]; Fundacao Calouste Gulbenkian [96542]; Fundacao para a Ciencia e Tecnologiainfo:eu-repo/semantics/publishedVersio

Optimization of a homogeneous ternary solvent system for the quantification of lead in crystal sugar samples.

During sugar production, contamination of the sugar by potentially toxic metals may occur. Therefore, it is necessary to develop methods to quantify these contaminants. Analytical method for monitoring of lead in sugar samples was developed with the use of homogeneous ternary system of solvents and UV-Vis spectrophotometry. Ternary system was optimized using multivariate experiments and the best condition was: 10% water, 80% ethanol and 10% methyl isobutyl ketone. As the complexing agent, monosodium 4-(2-pyridylazo) resorcinol used. Calibration curve was linear from 0.64 to 5.00 mg L-1, ABS = 0.0873 [Pb2 +] - 0.0032 and R? = 0.9988. The limit of quantification was 0.53 mg L-1 and limit of detection was 0.45 mg L-1 with 95% confidence level, the standard addition curve was linear, ABS = 0.0736 [Pb2+] + 0.0846 And R? = 0.9971. Three samples were analyzed in triplicate and the concentration of lead obtained ranged from 84.74 ? 3.70 mg kg-1; 69.93 ? 11.84 mg kg-1 and 76.45 ? 7.12 mg kg-1. For the standard addition curve, the concentration found was approximately 230.00 mg kg-1. Considering the Brazilian standard, the lead concentration should not exceed 2.00 mg kg-1, thus, it?s concluded that the values obtained were not within the norm for this metal

Acute and sub chronic toxicity study of aqueous extract from the leaves and branches of Campomanesia velutina (Cambess) O. Berg.

Ethnopharmacological relevance: Campomanesia velutina leaves and branches infusions are used in Brazilian folk medicine to treat diarrhea and to ameliorate intestinal cramps, respectively. Aim of the study: Carry out the acute and sub chronic pre-clinical evaluation and thus assess the safety and toxicological potential of the specie. Materials and methods: In vivo toxicity was evaluated by acute and sub chronic toxicity assays conducted according to the guidelines of the Brazilian Agency of National Health Surveillance (Ag?ncia Nacional de Vigil?ncia Sanit?ria ? ANVISA). For acute toxicity evaluation, a single dose of aqueous extracts from the leaves (AEL) and branches (AEB) of Campomanesia velutina were orally administered to mice at doses of 300, 600 and 1200 mg/kg. Then, the animals were observed for 14 days. In the sub chronic study, the extracts were orally administered to mice for 14 days at doses of 300, 600 and 1200 mg/kg. To assess the toxicological effects, animals were closely observed on general behavior, clinical signs of toxicity, body weight, food and water intake. At the end of the experiment, it was performed biochemical and hematological evaluations, as well as histopathological analysis from the following organs: brain, heart, lungs, liver, stomach, small intestine (section) and left kidney. Preliminary phytochemical analysis was performed using thin layer chromatography (TLC) and colorimetric pharmacognostic tests. Results: In oral acute assay, treatment with AEB at the major dose (1200 mg/kg) caused diarrhea, abdominal cramps and tremors in females. These effects were reversed at 4th hour. Normochromic normocytic anemia was observed in males treated with AEL 300 mg/kg and AEB 600 and 1200 mg/kg as well as in females treated with AEB 300 and 1200 mg/kg. The kidney of all treated animals showed moderate inflammation and a few hemorrhagic points. In sub chronic assay, treatment with AEL 600 mg/kg, AEL 1200 mg/kg and AEB 1200 mg/kg caused hyper excitability in females that was not reversed. Treatments also had impact on weight gain and the relative weight of males? brain was increased on group treated with AEL 300 mg/kg, AEB 300 and AEB 1200 mg/kg. Although changes in hematological parameters were not observed, serum creatinine levels were significantly higher in males treated with AEB 300 mg/kg. Besides, the heart of all treated animals showed intense hyperemia. Preliminary phytochemical analysis revealed the presence of flavonoids, tannins and phenolic compounds. Conclusions: Toxicity signs were mainly observed after treatment with AEL and AEB at the two highest tested doses (600 and 1200 mg/kg), suggesting that the extracts are relatively safe at its effective dose (300 mg/kg). However, alterations on hematological and biochemical parameters and on the kidney and heart of the animals were not closely related with the dose, implying caution on its use

FIRST REPORT ON OTOTOXICITY OF MEGLUMINE ANTIMONIATE

Pentavalent antimonials are the first drug of choice in the treatment of tegumentary leishmaniasis. Data on ototoxicity related with such drugs is scarcely available in literature, leading us to develop a study on cochleovestibular functions. Case Report: A case of a tegumentary leishmaniasis patient, a 78-year-old man who presented a substantial increase in auditory threshold with tinnitus and severe rotatory dizziness during the treatment with meglumine antimoniate, is reported. These symptoms worsened in two weeks after treatment was interrupted. Conclusion: Dizziness and tinnitus had already been related to meglumine antimoniate. However, this is the first well documented case of cochlear-vestibular toxicity related to meglumine antimoniate
