1. Microbial contamination of luncheon meat sliced and packaged at supermarkets in Porto Alegre, Brazil
Background: Ready-to-eat (RTE) foods are considered a high risk food group, since they are often consumed without a cooking step. Luncheon meat, a RTE food widely consumed in Brazil, is traditionally produced as industrially vacuum-packaged loaves and afterwards is sliced and re-packaged at retail stores. Since this practice may pose an additional hazard of

2. "Metodologia para Determinação de Hidrocarbonetos Policíclicos Aromáticos em Sedimentos e Solos Periféricos à Represa São Pedro Juiz de Fora, MG"
Polycyclic Aromatic Hydrocarbons are important substances that are produced by many antropogenic sources, among that, the most significant is burns of fossil fuels and biomass which releases these compounds to the environment. Sediments and soils are important matrix to study contamination and their effects because they are able to adsorb organic compounds s

4. Morphological study on the effects of high sound pressure and Ginkgo biloba EGb 761 dry extract to the cochlea cell architecture of adult guinea pigs / "Estudo da ação do nível elevado de pressão sonora e do extrato seco de Ginkgo biloba EGb761 na citoarquitetura da cóclea de cobaias adultas"
Human exposition to excessive sound levels has been a cause for preoccupation since the early stages of our civilization. In the Modern Era, sound levels have increased not only at work but also during social and leisure activities, leading the hearing loss induced by high levels of sound pressure to be considered the second most important cause of deafness.

6. Effects of soil moisture and temperature on preharvest invasion of peanuts by the Aspergillus flavus group and subsequent aflatoxin development.
Four soil temperature and moisture treatment regimens were imposed on Florunner peanuts 94 days after planting in experimental plots in 1980. At harvest (145 days after planting), the incidence of the Aspergillus flavus group and the aflatoxin concentration were greatest in damaged kernels. Extensive colonization of sound mature kernels (SMK) by the A. flavu

7. Factors Influencing Aflatoxin Accumulation in Peanut Kernels and the Associated Mycoflora1
Accumulation of aflatoxin in Spanish peanut kernel samples from different geographical areas in Texas during 1966, as detected by the thin-layer chromatographic method, was relatively low. Analysis of samples obtained from growers using artificial drying equipment (forced air and supplemental heat), when windrow conditions were unfavorable for rapid drying,

8. Mercuric ion reduction and resistance in transgenic Arabidopsis thaliana plants expressing a modified bacterial merA gene.
With global heavy metal contamination increasing, plants that can process heavy metals might provide efficient and ecologically sound approaches to sequestration and removal. Mercuric ion reductase, MerA, converts toxic Hg2+ to the less toxic, relatively inert metallic mercury (Hg0) The bacterial merA sequence is rich in CpG dinucleotides and has a highly sk
