1. Cadmium accumulation and toxicity in watercress (Barbarea verna), chicory (Cichorium endivia) and rocket (Eruca sativa) plants
ABSTRACT Some vegetables have the ability to accumulate cadmium (Cd)at levels that are toxic to most other plants. The objective of thisstudy was to evaluate the Cd accumulation and its toxic effects on edible vegetables. Three species were tested: watercress (Barbarea verna); chicory (Cichorium endivia); rocket (Eruca sativa) and four Cd doses (0; 1.5; 3.0;

2. Atividade antioxidante e composição fenólica de legumes e verduras consumidos no Brasil / Antioxidant activity and phenolic composition of vegetables consumed in Brazil
Vegetables are widely consumed foods in the diet of Brazilians. A few years ago, studies on compounds present in vegetables such as carotenoids, vitamins, fibers and phenolic compounds have been conducted due to their biological effects and benefits to human health. Phenolic compounds are distinguished mainly by their antioxidant power. The aim of this study

3. Watercress crop to salinity using a NFT hidroponic system / Resposta da Cultura do Agrião à Salinidade Utilizando um Sistema Hidropônico do Tipo NTF
After the Brazilian agriculture started to be outstanding in the scenery of the scientific researches, the great challenge started to be the productivity standardization in whole national territory. One of the main focus is being the semi-arid area for its water scarcity, so much quantitative as qualitative, for being an area with low annual precipitation an

4. APLICATION OF THE MICROBIOLOGICAL METHOD DEFT/APC AND DNA COMET ASSAY TO DETECT IONIZING RADIATION PROCESSING OF MINIMALLY PROCESSED VEGETABLES / Aplicação do método microbiológico DEFT/APC e do Teste do Cometa na detecção do tratamento com radiação ionizante de hortaliças minimamente processadas
Marketing of minimally processed vegetables (MPV) are gaining impetus due to its convenience, freshness and apparent healthy. However, minimal processing does not reduce pathogenic microorganisms to safe levels. Food irradiation is used to extend the shelf life and inactivation of food-borne pathogens. Its combination with minimal processing could improve th

5. Evaluation of ozone efficiency as a sanitizer on minimally processed vegetables. / Avaliação da eficiencia do ozonio como sanitizante em hortaliças folhosas minimamente processadas.
Minimally processed fruits and vegetables are sold already washed, peeled, cut or sliced, sanitized, packaged and cold-storaged. Consumption of this kind of food has increased markedly in the last decades due to people interest for fresh and practice foods. High handling during its processing, increasing of its shelf-life and absence of remarkable technologi

6. Use of a molecular tool for the evaluation of Listeria monocytogens in minimally processed vegetable salad. / Emprego de um método molecular para avaliar a presença de Listeria monocytogenes em saladas de hortaliças folhosas minimamente processadas.
The increasing demand for fresh fruits and vegetables, associated with the desire of convenient goodies, is causing an expansion on the market share of minimally processed products (MP). Minimal processing includes operations such as washing, cutting, peeling and packaging of the product. Amongst pathogenic microorganisms that can be transmitted by MP vegeta

7. Irradiação de agrião (Nasturtium oficinallis) minimamente processado: aspectos microbiológicos e sensoriais / Irradiation of watercress (Nasturtium officinale) minimally processed: microbiological and sensory aspects
Consumer attitudes towards foods have changed in the last two decades increasing requirements for freshlike products. Consequently less extreme treatments or additives are being required. Minimally processed foods have freshlike characteristics and satisfy this new consumer demand. Besides freshness, the minimally processing also provide convenience required

8. Evaluation of the nitrate text in folhosas hortaliças produced by different systems of culture. / Avaliação do teor de nitrato em hortaliças folhosas produzidas por diferentes sistemas de cultivo.
Nitrate is naturally present in vegetables as a nitrogen source for their growth, the amount depending on genetic factors, the availability of this nutrient for the plant and environmental factors. It has been estimated that more than 70% of the nitrate ingested daily by man is supplied by vegetables. The present work evaluated the nitrate content in leafy v

9. Invading freshwater snails and biological control in Martinique Island, French West Indies
Eight alien freshwater snail species were introduced into Martinique Island during the last 50 years. The introduced snails include four planorbids (Biomphalaria straminea, Helisoma duryi, Amerianna carinata and Gyraulus sp.), three thiarids (Melanoides tuberculata, M. amabilis and Tarebia granifera) and one ampullarid (Marisa cornuarietis). Four of these sp

10. Aeromonas do grupo A. hydrophila em amostras de hortaliças comercializadas na cidade de São Paulo / Motile Aeromonas spp. in retail vegetables from São Paulo, Brazil
A total of 90 retail vegetable samples, including 30 of lettuce, 30 of water-cress and 30 of escarole were examined for the presence of Aeromonas of the A. hydrophila group, using two different isolation methods. One of the methods envolved direct plating on starch-ampicinin agar for the purpose of enumeration and the other one, after enrichment in trypticas

11. Direct Modification of the Proinflammatory Cytokine Macrophage Migration Inhibitory Factor by Dietary Isothiocyanates*
Isothiocyanates are a class of phytochemicals with widely reported anti-cancer and anti-inflammatory activity. However, knowledge of their activity at a molecular level is limited. The objective of this study was to identify biological targets of phenethyl isothiocyanate (PEITC) using an affinity purification approach. An analogue of PEITC was synthesized to
