Inhibiting Effect of Electrochemically Activated Aqueous Solutions on Growth Biofilms

In the present work, we examined intraperitoneal (3 and 6 mg/kg body weight [bw]; Rot-3-ip and Rot-6-ip, respectively) andoral (50 and 100 mg/kg bw; Rot-50-po and Rot-100-po, respectively) rotenone induced PD modeled Wistar rats to evaluatechanges in various haematological parameters. While Rot-3-ip for 21 days and Rot-50-po for 28 days caused majorParkinson’s disease (PD)-related alterations, Lewy bodies were only detected in Rot-3-ip rats. The Rot-6-ip and Rot-100-potreatments caused lethal toxicity. The ip and po rotenone doses significantly (p < 0.05) and dose dependently altered severalhaematological variables (haemoglobin [Hb], red blood cells [RBCs], white blood cells [WBCs] and packed cell volume[PCV])

Quality of life and healthy aspects in agribusiness workers / Qualidade de vida e aspectos saudáveis em trabalhadores da agroindústria

to evaluate quality of life and its relationship to lifestyle along with the personal and work characteristics of agro-industry workers from Goias, Brazil. A cross-sectional, descriptive and quantitative study, using the WHOQOL-BREF instrument as well as personal and work data, the data collection occurred in 2014. A bivariate analysis was used to check for associations between the predictor variables and the analyzed outcomes. Variables with p < 0.20 and potential confounding variables: gender, age, income and marital status were included in multiple linear regression models. The perception of the quality of life of workers showed better scores for the social domain and worse for environment, obtaining significance for the factors associated with quality of life: physical activity, education, skin color, work related accidents, income and body mass index. In order to perform the multifactorial analyses, the associated independent factors were confirmed in the regression analysis, with the inclusion of the variables gender, marital status and alcohol consumption. The workers have lifestyles that interfere with the perception of their quality of life. All of the domains evaluated in this study were shown to possess this interference, with prevalence toward a lack of physical activity and the occurrence of work related accidents.

Estudo transversal, descritivo e quantitativo; utilizou o instrumento WHOQOL-BREF e dados pessoais e laborais; a coleta de dados ocorreu em 2014. Realizou-se análise bivariada para verificar associações entre as variáveis preditoras e os desfechos analisados. Variáveis com p < 0,20 e potenciais variáveis de confusão: sexo, idade, renda e estado civil foram incluídas em modelos de regressão linear múltipla. A percepção da qualidade de vida dos trabalhadores mostrou melhores escores para o domínio social e piores para o ambiental, obtendo significância para os fatores associados à qualidade de vida: atividade física, escolaridade, cor da pele, acidente de trabalho, renda e índice de massa corporal. Para as análises multifatoriais os fatores independentes associados foram confirmados na análise de regressão, com a inclusão das variáveis sexo, estado conjugal e uso de bebida alcoólica. Os trabalhadores possuem estilos de vida que interferem na percepção da qualidade de suas vidas, observadas em todos os domínios avaliados, com prevalência de não realização de atividade física e ocorrência de acidentes de trabalho.

Earthworm Pontoscolexcorethrurus and Nitrogen Mineralization Rate in Incubation Experiment with Different Quality Organic Matters from Sugaragro-Industry Waste.

To investigate the effect of earthworm inoculation on N mineralization rates of different quality organic matters from sugar agro-industry waste, we conducted a green house incubation experiment for 14 weeks in pots containing 7 kg dry soil. There are 12 treatment combinations.Factor I waswith (P) and without inoculation of P.corethrurus (N). Factor II was the type of OM which consisted of six levels: (1) without application of OM (control), (2) cow manure (CM), (3) filter cake (FC), (4) sugarcane trash (ST), (5) a mixture of CM + FC and (6) a mixture of CM + ST. The treatments were arranged in a factorial randomized block design with three replications. The amount of released N-NH4 +and N-NO3 - or mineral N was measured during incubation time from 1, 2, 4, 8, and 14 weeks after inoculation of earthworms. There was a significant effect of earthworm inoculation on N mineralization rate of different quality organic matters. Overall, rate of net N mineralization were higher in treatments with earthworm inoculation than without earthworm inoculation and the magnitude of the increase appears to dependent on the quality of organic matters. The largest difference were seen on ST and CM+ST treatments with the increase by 90 % and 157 % and the constant of N mineralization rate by 0.0147 and 0.0180 week-1 for the treatment with earthwormsinoculation.These results suggested that application of sugar agro-industry waste although having low quality can improve soil N availability in sugarcane land when aided by P.corethrurus activity.

Qualidade dos produtos derivados de carne e leite, industrializados pelas agroindústrias de Frederico Westphalen, RS / Quality of the products derived from meat and milk, industrialized by the agrobusiness of Frederico Westphalen, RS

O trabalho teve como objetivo avaliar a qualidade microbiológica dos produtos alimentícios industrializados pelas agroindústrias de Frederico Westphalen - RS. Quando se fala em qualidade dos produtos agropecuários e seus derivados, é interessante notar a preocupação predominante de abordar a questão de uma perspectiva quase que puramente higiênico-sanitária, em que a contaminação microbiológica seria responsável maior pela perda de qualidade dos produtos e pelos malefícios à saúde. Na primeira etapa do trabalho, foram coletadas amostras de leite, queijo, frescal e maturado (empresa A), leite, queijo frescal, maturado e ricota (empresa B), salame frescal, maturado e linguiçinha (empresa C), carne in natura, salame frescal e maturado (empresa D). As amostras foram coletadas e acondicionadas para que não houvesse contaminação. Foram realizadas análises microbiológicas (Salmonella, coliformes totais e fecais), segundo as normas do manual de Métodos de Análises Microbiológicas de Alimentos, 1997. No segundo momento, foram apresentados os resultados às empresas, sugerindo melhorias no processamento e em seus estabelecimentos. Na terceira etapa, realizou-se nova bateria de análises. Os resultados obtidos na primeira etapa foram negativos para todos os produtos quanto a Salmonella. As análises de coliformes totais e fecais, para a carne e o salame maturado, deram resultados satisfatórios, enquanto que para os outros produtos os índices de coliformes foram acima do permitido pela legislação. Durante o desenvolvimento do projeto foi dado um assessoramento às indústrias quanto às condições higiênico-sanitárias dos estabelecimentos e da manipulação dos produtos, além de melhorias quanto à estrutura física. Na terceira etapa, os resultados obtidos para Salmonella, em todos os produtos, foram negativos. O salame frescal apresentou resultado satisfatório quanto a coliformes totais e fecais. O restante dos produtos apresentou índices de coliformes acima do permitido pela leg...

This study aims at assessing the microbiologic quality of food products manufactured by agro- industries of Frederico Westphalen. When talking about quality of agribusiness products and byproducts, it is interesting to notice that the main concern is to focus the issue from a quasi purely hygienic-sanitary perspective, where microbiologic contamination would be responsible for the product quality loss and health threat. During the first step of the study, it was collected samples of milk, soft and cured cheese (Enterprise A), milk, soft, cured and cream cheese (enterprise B), soft and cured salami and sausage (enterprise C ), in natural meat, soft and cured salami (enterprise D). The samples were collected and securely wrapped to prevent contamination. Microbiologic analyses were carried out (salmonella, total and fecal feces), according to the norms of Manual de Métodos de Análises Microbiológicas de Alimentos, 1997 (Manual of Food Microbiologic Analyses Methods). The second step consisted in presenting the results to the enterprises, suggesting improvement in the processing and at the plants. As a third step, more analyses were carried out. The results obtained from the first study were negative for all the products regarding the salmonella. The analyses of total and fecal feces, concerning the meat and the cured salami, showed satisfactory results, while the other products showed feces indexes above those permitted by legislation. During the project development, it was given support to the industries regarding hygienic- sanitary conditions, product manipulation and building improvement. In the third step, the salmonella results, in all products, were negative. (...)
