1. Selection of aggressive pathogenic and solopathogenic strains of Ustilago maydis to improve Huitlacoche production
ABSTRACT Ustilago maydis is a basidiomycete known as the causative agent of 'common smut', worldwide disease of maize that is recognized by the galls it forms, which have considerable potential as a gourmet food. Results of infection are quite variable, even under optimal greenhouse conditions. In order to find pathogenic strains able to be used as a highly

2. Variedades com curvatura prescrita : resultados de existÃncia, unicidade, rigidez e bifurcaÃÃo / Manifolds with prescribe curvature: results of existence uniqueness, rigidity and bifurcation
We present several results of existence, uniqueness, rigidity and bifurcation for the problem of prescribing various geometric structures on Riemannian manifolds, among which include: i) deformation and rigidity for 2k-Einstein structures on manifolds with constant (2k − 2)-sectional curvature; ii) conformal deformation of metrics in the context of the

3. A comparative structural cytogenetic study in three allopatric populations of Astyanax scabripinnis (Teleostei: Characidae)
Individual samples from five populations of the characid fish Astyanax scabripinnis (Jenyns, 1842) from the Tietê and Paranapanema river basins (Brazil) were studied. All individuals analyzed presented 50 chromosomes but three different karyotypic forms were observed. Additionally, some individuals of one karyomorph presented a macro supernumerary chromosom

4. Marsupial extension in terrestrial isopods (Crustacea, Isopoda, Oniscidea)
In Oniscidea, the marsupium is a ventral pouch where the offspring develop independently of an external water source. The marsupium is formed by five pairs of overlapping oostegites that develop in the females during their reproductive period. In this study, ovigerous females of 35 species were dissected, their oostegites were extracted, and the intra-marsup

5. Relatos de experiencia, saber pedagógico y reconstrucción de la memoria escolar
The article explores the methodological, theoretical and political potentialities of the narrative documentation of pedagogical experiences as an instrument of educational action research among teachers and as a modality of collaborative work orientated to the reconstruction of the pedagogical memory of the school and to the educational change. Thus, it prop

6. Cebus cf. apella exhibits rapid acquisition of complex stimulus relations and emergent performance by exclusion
A "second generation" matching-to-sample procedure that minimizes past sources of artifacts involves (1) successive discrimination between sample stimuli, (2) stimulus displays ranging from four to 16 comparisons, (3) variable stimulus locations to avoid unwanted stimulus-location control, and (4) high accuracy levels (e.g., 90% correct on a 16-choice task i

7. Genetic-morphometric variation in Culex quinquefasciatus from Brazil and La Plata, Argentina
Variation among natural populations of Culex (Culex) quinquefasciatus Say is associated with different vectorial capacities. The species Cx. quinquefasciatus is present in the equatorial, tropical and subtropical zones in the Brazilian territory, with intermediate forms between Cx. quinquefasciatus and Culex pipiens occurring in regions of latitudes around 3

8. A trama da vida
On the basis of the knowledges are fragmented and placed in watertight compartments, this thesis proposes that art, by its transdisciplinary characteristics, may contribute to bridging, to make reconnections, entanglement. The complex thinking is the inspiration and literature was the method chosen to shows this possible dialogue. The narrative is woven by f

9. Química supramolecular de fármacos antirretrovirais inibidores nucleosídeos de transcriptase reversa: novas formas cristalinas e alteração de propriedades de estado sólido / Supramolecular chemistry of antiretroviral nucleoside reverse transcriptase inhibitor drugs
Solid state properties are directly related to drug performance. Among all physical and chemical properties dependent on the crystal phase of a drug, stability and solubility are the main ones that alter its bioavailability. In this way, molecular crystal engineering is a strategy to improve solid state properties of drugs related to their efficacies. In thi

10. Interação entre IQGAP1 e actina mediado por CDC42 e RAC1
IQGAP1 stimulates branched actin filament nucleation by activating N-WASP, which in turn activates the Arp2/3 complex. N-WASP can be activated by other factors, including GTP-bound forms of Cdc42 and Rac1, which also bind IQGAP1. We report here the use of purified proteins for in vitro binding and actin polymerization assays, and of fluorescence resonance en

11. Identificação e validação de marcadores moleculares indel e SNP para lipoxigenases de sementes de soja / Identification and validation of indel and SNP molecular markers for soybean seed lipoxygenases
The oxidative degradation of fatty acids from soybean oil fraction, that occurs during the grain processing, develop a flavor of unripe been that modify the palatability and therefore the acceptability of soybean products, resulting in problems for the food industry. The enzyme lipoxygenases (linoleate: O2 oxidoreductase, EC 1.13.11.12), that catalyses this

12. Analise molecular do loco C4/CYP21 : impacto da variabilidade alelica provocada por recombinações sobre os metodos de avaliação de mutações / Molecular analysis of C4/CYP21 locus : influence of allelic variability caused by recombinations on current methods of mutation detection
Congenital adrenal hyperplasia is caused by deficiency of one of the five enzymes responsible for cortisol synthesis in the steroidogenesis. More than 90% of the cases occur due to deficiency of 21-hidroxilase (21-OH). The haploid human genome bears two copies in tandem of 21-OH coding gene, CYP21A2 and CYP21A1P. Although the two copies are approximately 98%
