1. Acceptance of a food of animal origin obtained through genetic modification and cloning in South America: a comparative study among university students and working adults
AbstractWith the aim of comparing the acceptance of milk obtained from cloned, genetically modified (GM) and conventionally bred cows among working adults and university students, and identifying and characterizing typologies among both subsamples in terms of their preferences, a survey was applied to 400 people in southern Chile, distributed using a simple

2. Genetic diversity analysis among pigeonpea genotypes adapted to South American regions based on microsatellite markers
The pigeonpea [Cajanus cajan (L) Millspaugh] is one of the most important perennial legume crops utilized in the food, fodder, soil conservation, crop-livestock integrated systems, reclaiming of degraded pastures and symbiotic nitrogen fixation. Microsatellite markers were used to estimate the genetic diversity of 77 pigeonpea genotypes selected from the ger

3. Characterization of storage proteins, amino acid profile and enzymes involved in lysine metabolism in genetic modified barley (Hordeum vulgare L.) / Caracterização de proteínas de reserva, perfil de aminoácidos e enzimas envolvidas no metabolismo de lisina em cevada (Hordeum vulgare L.) geneticamente modificada
Cereals represent an important source of protein to human food and animal feed. However, they are characterized by low nutritional quality of proteins due to the unbalanced composition of amino acids, caused by the excess of the amino acids proline and glutamine and deficiency of lysine, threonine and tryptophan. The prolamin storage proteins constitute 50%

4. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

5. Transgenia agrícola e modernidade : um estudo sobre o processo de inserção comercial de sementes transgênicas nas sociedades brasileira e argentina a partir dos anos 1990 / Transgenics in agriculture and modernity : a study of the commercial introduction of transgenic seeds into the Brazilian and Argentinean societies since 1990
The commercial use of transgenic seeds in agriculture since the end of the 20th century and its disseminated use in the beginning of the 21st century lead not only to radical changes in the world s agriculture sector, now technologized in all spheres of the productive process, but also to radical changes into the concepts of seeds and life, with economic, so

6. Biological, systemic and reproductive evaluation in Wistar rats feed on genetically modified soybean resistant to the glyphosate. / Respostas biológica, sistêmica e reprodutiva de ratos Wistar alimentados com soja geneticamente modificada resistente ao glifosato
The most cultivated genetically modified plant in Brazil is the soybean [Glycine max (L.) Merr.] resistant to the systemic herbicide glyphosate. There are 12.3 millions of cultivated hectares. This soybean was obtained through the introduction of the gene that codes for the 5-enolpyruyilshikimic-acid3-phosphate synthase enzyme, (EPSPS, E.C 2.5.1.19, CP4), of

7. Biosafety of Cry1Ac protein, synthesized by the genetically modified cotton, on stingless bees and honeybees / Biossegurança da proteína Cry1Ac, sintetizada pelo algodão geneticamente modificado, em abelhas indígenas sem ferrão e africanizadas
Genetic engineering techniques offer opportunities for the developement of insect-resistant plants due to the synthesis of entomotoxical proteins by plants. To evaluate the biosafety of GM cotton in relation to pollinators, bioassay methods were developed for rearing larvae of Trigona spinipes and Apis mellifera, bees commonly found in cotton flowers in Braz

8. Uso de marcadores microssatélites para avaliação genética de populações de Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) no Estado da Bahia / Microssatellites markers applied to genetic evaluation of populations of Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) in Bahia State, Brazil
Melipona mandacaia, is an indigenous stingless bee (Meliponini Tribe), an endemic species of the semi-arid of the northeast of Brazil. The original flora of the caatinga has been altered by the human action. This alteration reduces the food resources and the places available for nesting, so this affects the dispersion and the genetic flow of the populations

9. Chromatin supraorganization and extensibility, and nuclear composition in mouse cells / Supraorganização e extensibilidade da cromatina, e composição nuclear em celulas de camundongo
Aging may be defined as the changes that take place in an organism with time. This process, in biology, is called senescence. Cellular senescence is observed in isolated cells, and has been studied typically in cultured cells, but its occurrence in vivo has been shown only in some mammalian tissues. Chromatin changes that take place with cellular senescence

10. A bioética e os alimentos transgênicos no âmbito do código de defesa do consumidor
The present monographic work intends to demonstrate the most relevant aspects of the genetically modified grains, the transgenics, mainly how they have been inserted in the consumption market. The question is crucial, once the technical and scientific knowledges cant predict, exactly, its human health and ecological outcomes. Therefore, initially this paper

11. Marx visits Monsanto: to think the agrarian question on the XXI century. / Marx visita a Monsanto: para pensar a questão agrária no século XXI.
This work seeks to relate the ressurgence and protagonism of the peasant movements on the space of world articulation and alternatives building to neoliberalism, identified with the World Social Forum (WSF) process. On the peasants discourse to globalization in this context, the opposition to the genetically modified organisms (transgenics) in its introducti

12. Novel Food-Grade Plasmid Vector Based on Melibiose Fermentation for the Genetic Engineering of Lactococcus lactis
The α-galactosidase gene (aga) and a gene coding for a putative transcriptional regulator from the LacI/GalR family (galR) of Lactococcus raffinolactis ATCC 43920 were cloned and sequenced. When transferred into Lactococcus lactis and Pediococcus acidilactici strains, aga modified the sugar fermentation profile of the strains from melibiose negative (Mel−
