1. 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

2. Toxinas protÃicas de sementes de soja [Glycine Max (L.) Merr.]: aspectos moleculares e funcionais / Toxic proteins from soybean seeds [Glycine max (L.)Merr.]: molecular aspects and functional analysis
A soja (Glycine max) Ã uma espÃcie de grande valor econÃmico para o Brasil dada a multiplicidade de uso de seus grÃos na alimentaÃÃo animal e na indÃstria. Embora o Brasil seja o segundo maior produtor mundial dos grÃos, as perdas na produtividade em campo ainda sÃo considerÃveis, principalmente Ãquelas causadas por nematÃides do gÃnero Meloidog

3. Identificação e mapeamento de genes para uso na seleção assistida de genótipos de soja com ausência do inibidor de tripsina Kunitz e lipoxigennases
Soybean (Glycine max (L.) Merrill) is a food with high levels of proteins, minerals and fibres, and a reduced amount of saturated fat bringing benefits to humans health. However, the use of the product for human and animal feeding is limited to the presence of some antinutritional factors, as trypsin inhibitors and lipoxygenases enzymes. The development of

4. Estudo da atividade antiinflamatÃria e antinociceptiva da lectina isolada da alga marinha vermelha Hypnea cervicornis (J. Agardh). / Study of antiinflammatory and antinociceptive activities of a lectin isolated from the red marine alga Hypnea cervicornis (J. Agardh)
Lectins are (glyco)proteins that can recognize and reversibly bind to carbohydrates or other substances derived from sugars. They are found throughout animal and vegetal kingdoms. Hypnea cervicornis is a species of marine red algae found in Northeast of Brazil from which was isolated the lectin Hypnea cervicornis aglutinin (HCA), a polypeptide containing 90

5. Connexins in the early development of the African clawed frog Xenopus laevis (Amphibia): The role of the connexin43 carboxyl terminal tail in the establishment of the dorso-ventral axis
Connexins are a family of related proteins identified in vertebrate forming gap junctions, which mediate cell-to-cell communication in early embryos, with an important role in establishing embryonic asymmetry and ‘communication compartments’. By in situ hybridization, immunocytochemistry, reverse transcriptase PCR (RT-PCR) and western blotting we show th

6. INFLUENCE OF A PHYTOGENIC ADDITIVE ON THE BLOOD LEVELS OF HEIFERS JERSEY / INFLUÊNCIA DE UM ADITIVO FITOGÊNICO NOS NÍVEIS SANGÜÍNEOS DE NOVILHAS JERSEY
The experiment was carried out at Itaboapaba Farm, in Silveira Martins RS, Brazil, and was conducted from March 1 up to June 30, 2006, taking 122 days. This study was composed by 20 heifers Jersey race, with average weight of 199 kg and average age of 12 months. The heifers were divided randomly into two treatments: (1) control, in which the basic diet was s

7. Avaliação dos efeitos da adição do óleo essencial de orégano (Origanum vulgare) na dieta, sobre a fisiologia e a produtividade de codornas japonesas (Coturnix coturnix japonica)
The antibiotic use as growth promotional is being gradually prohibited due to the possible risk of drugs resistance for human pathogenic bacteria resulting in an increasing interest for produced organic foods, that the public in general associated as healthful food. Between the options, the herbals extracts (amongst them the oregano, Origanum vulgare) are pa

8. Estudo sobre fontes de proteína de origem animal e vegetal em dietas para leitões em período de creche / Research about sources of animal and vegetal origin protein in diets for piglets in nursery period
A pesquisa foi conduzida no Setor de Suinocultura do Centro de Ciências Agrárias do Departamento de Zootecnia da Universidade Federal do Ceará. O experimento teve a duração de 42 dias e foi realizado com o objetivo de avaliar o desempenho zootécnico, a histomorfometria intestinal, o perfil microbiológico fecal, a ocorrência de diarréia, os indicador

9. Alterações em genes de zeina induzidas por variação somaclonal
Somaclonal variation was observed in plants regenerated from type I calli established from a maize inbred line Cat100-6. One of the variants, S1587. was self-polinated, giving rise to different progenies. Considering the plant and seeds morphological alterations, one of the progenies, 81587-17. was selected for further studies of seed storage proteins, zeins

10. Spatial distribution of two maternal messengers in Paracentrotus lividus during oogenesis and embryogenesis.
We demonstrated that two mRNAs that are synthesized during the vitellogenic period of oogenesis and that code for cell surface proteins are asymmetrically distributed in the unfertilized egg of Paracentrotus lividus. At fertilization, these RNAs rapidly localize in the cortical zone at the animal pole of the egg. They are then detected in the mesomeres and t

11. A maternal mRNA localized to the animal pole of Xenopus eggs encodes a subunit of mitochondrial ATPase.
We have previously isolated several cDNA clones of mRNAs that have the unusual property of being localized to either the animal pole or the vegetal pole of frog eggs. To gain insight into the function of these maternal mRNAs we have determined their DNA sequence and deduced the sequence of the proteins they encode. Here we report that An2, an mRNA localized

12. Developmental expression of the protein product of Vg1, a localized maternal mRNA in the frog Xenopus laevis.
Vg1 is a maternal mRNA localized in the vegetal cortex of Xenopus laevis oocytes, that encodes a protein homologous to the mammalian growth factor TGF-beta. Using a polyclonal antibody to a T7-Vg1 fusion protein, we have identified the native protein. We find that a single protein of Mr 40 kd is immunoprecipitated following in vitro translation of oocyte pol
