Crystallization and preliminary diffraction data of a platelet-aggregation inhibitor from the venom of Agkistrodon piscivorus piscivorus (North American water moccasin)

Applaggin (Agkistrodon piscivorus piscivorus platelet-aggregation inhibitor) is a potent inhibitor of blood platelet aggregation derived from the venom of the North American water moccasin, the protein consists of 71 amino acids, is rich in cysteines, contains the sequence-recognition site of adhesion proteins at positions 50-52 (Arg-Gly-Asp) and shares high sequence homology with other snake-venom disintegrins such as echistatin, kistrin and trigramin, Single crystals of applaggin have been grown and X-ray diffraction data have been collected to a resolution of 3.2 Angstrom. The crystals belong to space group P4(1)2(1)2 (or its enantiomorph), with unit-cell dimensions a = b = 63.35, c = 74.18 Angstrom and two molecules per asymmetric unit. Molecular replacement using models constructed from the NMR structures of echistatin and kistrin has not been successful in producing a trial structure for applaggin.

Reminiscências de Poe em contos machadianos

A reflection on Machado de Assis established relationship with the North American writer Edgar Allan Poe short stories is proposed here. A comparison between the short stories The Man of the Crowd and Só! [Lonely] is made in order to set the contrast between characters and theme treatment, fictionally elaborated by the two writers, considering the concept of influence within the framework of Comparative Literature.

Análise das matrizes sobre associativismo civil norteadoras da formação de trabalhadores para Ongs

This article presents research that aimed to discuss the theoretical frameworks about civil associativism prescribed by the trainers of non-governmental organizations (NGOs) workers. The requirements for civil associations made by trainers were analyzed based on two data and reference categories, named empirical and analytical. The empirical categories emerged from the data collected by means of interviews with trainers and also examining the documents that guided the course. The analytical categories were constructed from the literature review on the approaches of civil associations, which are: North American Third Sector Approach; Critical Approach to the Third Sector and Social Local Development (DSL in the Portuguese acronym). The study presents indications that could support the development of other research on the topic and, mainly academic knowledge for further development of new training processes for NGO workers.

An old taxonomic dilemma: the identity of the western south Atlantic lebranche mullet (Teleostei: Perciformes: Mugilidae)

The identification of the lebranche mullet in the western south Atlantic has long been problematical. In most recent works either Mugil liza Valenciennes and M. platanus Gunther, 1880 or M. liza and M. cephalus Linnaeus, 1758 were recognized from the region and more rarely the occurrence of only one species has been proposed but without sufficient morphological, biochemical or molecular data to allow the designation of the taxonomically appropriate name. Analysis of meristic and morphometric data taken from samples collected from Venezuela to Argentina, clearly indicates that there is only one species of lebranche mullet in the Caribbean Sea region and the Atlantic coast of South America and that Mugil liza is the appropriate name. The comparison of the combined data from all the samples of M. liza with the data taken from one sample of M. cephalus that originated in the Mediterranean, the possible locality from which type specimens were collected (Eschmeyer and Fricke, 2009), revealed significant differences indicating that they are different species. It is also suggested that individuals from the western north Atlantic identified as M. cephalus might represent a population of M. liza in this region.
