2. Physiological and biochemical changes during desiccation tolerance loss in millet (Pennisetum glaucum L.) seeds
ABSTRACT. The aim of this study was to evaluate the physiological and biochemical changes related to desiccation tolerance loss in millet seeds. The studied points of the germination process were determined according to the seed imbibition curve of the millet hybrid ADRF6010: control (0h), 3h of imbibition, 1 and 3 mm radicle. The seeds were dried on silica

3. The genomes of three Bradyrhizobium sp. isolated from root nodules of Lupinus albescens grown in extremely poor soils display important genes for resistance to environmental stress
Abstract Lupinus albescens is a resistant cover plant that establishes symbiotic relationships with bacteria belonging to the Bradyrhizobium genus. This symbiosis helps the development of these plants in adverse environmental conditions, such as the ones found in arenized areas of Southern Brazil. This work studied three Bradyrhizobium sp. (AS23, NAS80 and N

4. Morpho-anatomical, physiological and biochemical changes in rubber tree seeds
ABSTRACT The physical, physiological and biochemical changes during the development until the dispersal of rubber tree seeds were evaluated with the purpose of estimating the point at physiological maturity. A total of 30 plants were selected at different points in a commercial planting area and had their flowers marked during the anthesis and every 15 days

5. Characteristics of hemolytic activity induced by the aqueous extract of the Mexican fire coral Millepora complanata
Background Millepora complanata is a plate-like fire coral common throughout the Caribbean. Contact with this species usually provokes burning pain, erythema and urticariform lesions. Our previous study suggested that the aqueous extract of M. complanata contains non-protein hemolysins that are soluble in water and ethanol. In general, the local damage ind

6. Proteomic analysis of cytosolic proteins associated with petite mutations in Candida glabrata
The incidence of superficial or deep-seated infections due to Candida glabrata has increased markedly, probably because of the low intrinsic susceptibility of this microorganism to azole antifungals and its relatively high propensity to acquire azole resistance. To determine changes in the C. glabrata proteome associated with petite mutations, cytosolic extr

7. Condicionamento fisiolÃgico em matriz sÃlida durante o armazenamento de sementes de cafà (Coffea arabica L.) em diferentes graus de umidade / Physiological conditioning on solid matrix during storage of coffee seeds (Coffea arabica L.) with different moisture contents
Coffee seeds present poor storability with vigor loss in few months, which limits its use, restricting the seedling-producing time. The physiological conditioning or priming is a technique which is intended to promote improvement in seed performance. Evaluating the effect of different temperatures and periods of time in the physiological conditioning of soli

8. Estudos de alterações funcionais de macrofagos submetidos a hipoxia no modelo in vitro da leishmaniose / Studies of funcional alterations of macrophages submetted to hypoxia in ana in vitro model of leishmaniasis
Regions of low oxygen tension (hypoxia) are common features of inflamed/infected tissues. The analyses of cell phenotypic alterations by hypoxia are helpful for understanding of the pathological mechanisms and treatment resistance and for the development of cellular therapies. Macrophages, cells involved in the clearance of microorganisms from infected tissu

9. Over-activation of the Drosophila melanogaster hsp83 gene by selenium intoxication
Selenium is an important dietary micronutrient and an essential component of selenoproteins and the active sites of some enzymes, although at high concentrations it is toxic. We investigated diphenyl diselenide ((C6H5)2Se2 ) for its effects on the developmental stages of Drosophila melanogaster and found that in the larval and pupae stages the toxic threshol

10. Bioatividade do grão de amaranto : avaliação in vitro da atividade ligante de acidos biliares e inibidora da enzima conversora de angiotensina. / Bioactivity of the amaranth grain : in vitro assessment of the binding bile acids and inihibitory activity of the angiotensin converting enzyme.
Amaranth has been highlighted as an excellent alternative or complementary source of food protein due to its balanced amino acid composition. The culture of amaranth has been introduced into Brazil on account of its optimum nutritional (high protein content and better biological quality than that of cereal protein) and functional quality, apart from its agri

11. Bicho-mineiro do cafeeiro: anÃlise da digestÃo e inibiÃÃo de tripsina por extratos de folhas de mamona. / Coffee leaf miner: Digestion and trypsin inhibition using castor beam leaves extracts.
Coffee is a crop of great social and economic importance to Brazil and its production is affected by a number of pests and diseases. One of those pests is the coffee leaf miner, Leucoptera coffeella (GuÃrin-MÃneville, 1842) (Lepidoptera: Lyonetiidae) which can cause great losses in production. The forms of controlling the coffee leaf miner known and utiliz

12. Estudo da qualidade fisiolÃgica, bioquÃmica e ultra-estrutural durante o desenvolvimento e a secagem de sementes de soja / Physiological, biochemical and ultra structural studies during the development and drying of soybean seeds
During the development and drying, several protection mechanisms act on the maintenance of the physiological quality of the seeds. Studies on desiccation tolerance allow the understanding of the events associated with the maturation of orthodox seeds, such as soybean. Among the mechanism involved on desiccation tolerance, the activity of heat-resistant prote
