1. Contamination of corn grain for human consumption with transgenic sequences in Paraguay
Abstract Corn is one of the most important economic, social and cultural agricultural products in Paraguay, being the main ingredient of several typical foods. Due to the cross-pollination of this plant, it can be contaminated with transgenic maize pollen found in nearby fields. The general objective of this research was to evaluate the presence of transgeni

3. Transgênicos e o princípio de equivalência substancial
RESUMO Objetivamos discutir os principais argumentos que estão envolvidos no debate sobre a cientificidade do Princípio de Equivalência Substancial (PES), que afirma serem os OGM quimicamente equivalentes aos organismos selecionados pelas técnicas tradicionais de melhoramento, não requerendo, portanto, estudos toxicológicos adicionais. Problematizamos

4. microRNAs and the mammary gland: a new understanding of gene expression
MicroRNAs (miRNAs) have been identified in cells as well as in exosomes in biological fluids such as milk. In mammary gland, most of the miRNAs studied have functions related to immunity and show alterations in their pattern of expression during lactation. In mastitis, the inflammatory response caused by Streptococcus uberis alters the expression of miRNAs t

5. Biossegurança de alimentos transgênicos.
ABSTRACT: The use of transgenic plants on the human diet is a matter of great concern for the scientific community and the public in general. However, it is important to consider that before the release for human consumption, transgenic foods are submitted to an extensive series of rigorous tests. These tests includes the characterization of the expressed pr

6. Biossegurança ambiental de OGMs.
ABSTRACT: In 2005, there were 90 million hectares cultivated with GMOs by 8.5 million producers in 21 countries. In 2006, we commemorated 10 years of commercial production of GMOs. Currently there are 10 million farmers planting 100 million hectares. However, several points were raised concerning the environmental impact of GMOs: (1) risk of cultivated or wi

7. Biotecnologias agrícolas e sociedade: disputas sociais e regulamentação dos transgênicos no Brasil (19852005)
In this dissertation we present an historical panorama of the introduction of genetically modified organisms (transgenics) in Brazil, its repercussion and the social debate about several controverse aspects of this new technological product. In front of every groups view, we argued regarding the ambiguous centrality of technology at the contemporaneous world

8. Rastreabilidade de soja Roundup Ready® em produtos agrícolas e derivados: produção de materiais de referência e uso de marcadores AFLP / Roundup Ready® transgenic soybean traceability in agrifood products and derivatives: reference materials production and the use of AFLP markers
The introduction of soybean transgenic cultivars brought several changes in both world trade and regulation rules for producers and consumers, mainly in relation to certification, traceability, biosafety and labeling. Soybean is one of the largest commodities in the world trade and responsible for half of the Brazilian export incomings, present as raw materi

9. Evaluation of transgenic residues in foods in Brazil and development of analytical methodologies / Avaliação de resíduos de transgênicos em alimentos no Brasil e desenvolvimento de metodologias de análise
Desde a liberação da primeira variedade transgênica para consumo humano, o tomate Flavr savr, em 1995, o aumento no plantio e comercialização de organismos geneticamente modificados (OGMs) já aumentou mais de 50 vezes, atingindo em 2005 a cifra de 90 milhões de hectares plantados com algum tipo de OGM em 21 países. Estima-se que em 2006 esta cifra su

10. Transgênicos: opinião de professores e alunos de nível médio da área de nutrição / Transgenic foods: the opinion of secondary school teachers and students of the nutrition area
The employment of transgenics organisms divides opinions and, therefore, it is cause of great controversy. In spite of the existence of vast list of publications that register the current benefits of the development of the transgenia, inquietude signs are verified on the part of the consumers with relationship to your employment in the foods production.

O presente trabalho tem como objetivo analisar alguns aspectos concernentes às recentes inovações tecnológicas, e suas conseqüências para o meio ambiente. Embora não exista desenvolvimento social sem o progresso econômico e cientifico, não se pode conceber a existência de um Estado Democrático de Direito sem a preservação ambiental. A consolida�

12. Marker Rescue Studies of the Transfer of Recombinant DNA to Streptococcus gordonii In Vitro, in Foods and Gnotobiotic Rats
A plasmid marker rescue system based on restoration of the nptII gene was established in Streptococcus gordonii to study the transfer of bacterial and transgenic plant DNA by transformation. In vitro studies revealed that the marker rescue efficiency depends on the type of donor DNA. Plasmid and chromosomal DNA of bacteria as well as DNA of transgenic potato
