Glycine-rich proteins (GRP), serve a variety of biological functions. Acanthoscurrin is an antimicrobial GRP isolated front hemocytes-of the Brazilian spider Acanthoscurria gomesiana. Aiming to contribute to the knowledge of the secondary structure and stepwise solid-phase synthesis of GRPs` glycine-rich domains, we attempted to prepare G(101)GGLGGGRGGGYG(113) GGGGYGGGYG(123)GGy(126)GGGKYK(132)-NH(2), acanthoscurrin C-terminal amidated fragment. Although a theoretical prediction did not indicate high aggregation potential for this peptide, repetitive incomplete aminoacylations were observed after incorporating Tyr(126) to the growing peptide-MBHA resin (Boc chemistry) at 60 degrees C. The problem was not solved by varying the coupling reagents or solvents, adding chaotropic salts to the reaction media or changing the resin/chemistry (Rink amide resin/Fmoc chemistry). Some improvement was mode when CLEAR amide resin (Fmoc chemistry) was 32 used, as it allowed for obtaining fragment (G(113)-K(132) NIR-FT-Raman spectra collected for samples of the growing peptide-MBHA, -Rink amide resin and -CLEAR amide resin revealed the presence of beta-sheet structures. Only the combination of CLEAR-amide resin, 60 degrees C, Fmoc-(Fmoc-Hmb)Gly-OH and LiCl (the last two used alternately) was able to inhibit the phenomenon, as proven by NIR-FT-Raman analysis of the growing peptide-resin, allowing the total synthesis of desired 132 fragment Gly(101)-K(132). In summary, this work describes a new difficult sequence, contributes to understanding stepwise solid-phase synthesis of this type of peptide and shows that, at least while protected and linked to a resin, this GRPs glycine-rich motif presents all early tendency to assume beta-sheet structures.

Analysis of the elements of the Constitutional Order of the letter 1988 politics, with emphasis in the principles of this, a study on the intervention of the State in the private initiative by means of the Law of Recovery of Companies and Bankruptcies (law 11.101/05). New enterprise vision is admitted, over all in the interdependence between economic and social factors. Study on the globalization and the interdependence of economic and legal sciences in the construction of a legal optics in the search for the economic and social development, with the recognition of the interference of the Economy in the Right and its uneven importance. Still, we delineate the state intervention in the economic scope, of company and in the judicial recovery, as well as the consequences of such intervention in the involved credits in the judicial recovery and patrimony of the debtor in recovery. For such task, the elements of the Judicial Recovery, its principles and adequacy of these to the related ones in the chapter had been analyzed that turns on the national economic Order, describing the formal procedure for concession of the benefit of the Judicial Recovery and the principles in existing them. The forms of intervention of the State in the private economy were not disrespected, relating its direct and indirect performance as half of preservation of interests writings in the constitutional scope as public interest and preservation of the National economic Order. The regulating agencies as of direct state intervention were half not disrespected of the study for the relevance of the subject. It is revised national bibliography with incursions in French, Portuguese and North American comparative jurisprudence. One contributes in the aspect of the paper of the Judiciary Power in the protection of the companies in crisis and the social and economic impacts, over all in relation to the rights of the worked ones, credit and enterprise

La edición número 101 de Notas de Población contiene nueve artículos sobre temas de gran actualidad y relevancia futura en el campo de la investigación sociodemográfica en América Latina y el Caribe. La variada gama de asuntos que se abordan en la presente edición empieza con la aplicación del modelo de transición logística y las proyecciones de población, pasando por el análisis de la transición epidemiológica de la mortalidad infantil en América Latina y los determinantes de la fecundidad adolescente y su relación con la distribución territorial. Continúa con el envejecimiento, su relación con las condiciones de la vivienda, la migración calificada y el análisis del ciclo vital de las personas en relación con una esperanza de vida sana. Concluye con la percepción de la alteridad en la declaración del color y la raza en la encuesta de empleo del Brasil.
