Resumo Este artigo analisa conflitos envolvendo lideranças laicas e religiosas na esfera pública brasileira entre os anos de 2010 e 2013. O pastor Silas Malafaia protagoniza os confrontos aqui recapitulados, primeiro contra a deputada Iara Bernardi, na ocasião de um debate sobre o PLC 122/2006, passando por sua tão repercutida entrevista no programa de Marília Gabriela e culminando no embate travado contra o deputado Jean Wyllys por ocasião do PDC que ficou conhecido como da “cura gay”. Partindo de um diálogo entre a teoria social contemporânea e a filosofia política, avaliamos os dilemas apresentados a partir dos pontos de vista últimos em disputa, iluminando os sentidos que definem as respectivas concepções do que seja a vida numa sociedade laica e democrática.

La maladie de Wilson est une maladie héréditaire due à un déficit du transporteur du cuivre, l’ATP7B. Cette maladie se présente sous forme d’insuffisance hépatique aiguë ou chronique, pour lesquels le traitement médical actuel consiste en l’administration d’agents chélateurs, ce qui ne résulte cependant pas en une guérison complète de la maladie. La transplantation orthotopique du foie est le seul traitement définitif actuellement, avec tous les désavantages qu’elle comporte. Un traitement alternatif à cette option est donc souhaitable. Cette étude porte sur la faisabilité de la transplantation d’hépatocytes chez le modèle animal de la maladie de Wilson, le rat Long Evans Cinnamon (LEC), avec pour buts d’en déterminer la sécurité et l’efficacité tant sur le plan clinique (amélioration de la survie, prévention de l’hépatite) que pathologique. Douze rats LEC ont reçu une injection intrasplénique de 2,6 x 105 – 3,6 x 107 hépatocytes prélevés chez des rats donneurs de souche LE. Ils ont été suivis durant 6 mois puis sacrifiés. Ils ont ensuite été comparés à un groupe contrôle de douze autres rats LEC. Aucune différence significative n’a été notée au niveau du poids, du bilan hépatique et des concentrations de cuivre biliaire et hépatique. Cependant, une amélioration de l’activité oxydase de la céruloplasmine post-transplantation a été démontrée chez le groupe de rats transplantés (49,6 ± 31,5 versus 8,9 ± 11,7). Les rats transplantés ont aussi eu une amélioration sur tous les critères histologiques étudiés. Enfin, l’ARNm de l’atp7b a été retrouvé chez 58% des rats transplantés avec un taux d’expression de 11,9% ± 13,6 par rapport à un rat LE normal. L’immunohistochimie a quant à elle démontré la présence de l’atp7b chez tous les rats transplantés. Les résultats obtenus sont considérés favorables à ce traitement alternatif, et indiquent que la transplantation d’hépatocytes est une technique sécuritaire qui peut contribuer à renverser le processus pathologique en cours dans la maladie de Wilson.

Artificial pod inoculation was used to compare the relative aggressiveness of seven Colombian isolates of Moniliophthora roreri (the causal agent of moniliasis or frosty pod disease), representing four major genetic groupings of the pathogen in cacao (cocoa), when applied to five diverse cacao genotypes (ICS-1, ICS-95, TSH-565, SCC-61 and CAP-34) at La Suiza Experimental Farm, Santander Department, Colombia. The following variables were evaluated 9 weeks after inoculation of 2- to 3-month-old pods with spore suspensions (1.2 x 10(5) spores mL(-1)): (i) disease incidence (DI); (ii) external severity (ES); and (iii) internal severity (IS). IS was found to be of greatest value in classifying the reaction of the host genotype against M. roreri. Genetic variation reported between isolates and cacao genotypes was not matched by similar diversity in their aggressiveness. All isolates were generally highly aggressive against most cacao genotypes, with only two isolates showing reduced IS and ES reactions. There was considerable variation between clones in the IS and ES scores, but one cultivated clone (ICS-95) displayed a significant level of resistance against all seven isolates. This clone may be useful in cacao breeding initiatives for resistance to moniliasis of cacao.

The exact formula for the variance of the Index (R) of aggregation of Clark and Evans is derived. Due to the fact that R is a dimensionless number, its variance is independent of population density, being only a function of the sample size and so can be manipulated. © 1985 Springer-Verlag.

The suprachiasmatic nucleus, an essential diencephalic component of the circadian timing system, plays a role in the generation and modulation of behavioral and neuroendocrine rhythms in mammals. Its cytoarchitecture, neurochemical and hodological characteristics have been investigated in various mammalian species, particularly in rodents. In most species, two subdivisions, based on these aspects and considered to reflect functional specialization within the nucleus, can be recognized. Many studies reveal a typical dense innervation by serotonergic fibers in this nucleus, mainly in the ventromedial area, overlapping the retinal afferents. However, a different pattern occurs in certain animals, which lead us to investigate the distribution of serotonergic afferents in the suprachiasmatic nucleus of the Capuchin monkey, Cebus apella, compared to the marmoset, Callithrix jacchus, and two Rattus norvegicus lines (Long Evans and Wistar), and to reported findings for other mammalian species. Our morphometric data show the volume and length of the suprachiasmatic nucleus along the rostrocaudal axis to be greatest in C. apella > C. jacchus > Long Evans ≥ Wistar rats, in agreement with their body sizes. In C. apella, however, the serotonergic terminals occupy only some 10% of the nucleus' area, less than the 25% seen in the marmoset and rats. The distribution of the serotonergic fibers in C. apella does not follow the characteristic ventral organization pattern seen in the rodents. These findings raise questions concerning the intrinsic organization of the nucleus, as well as regarding the functional relationship between serotonergic input and retinal afferents in this diurnal species. © 2007 Elsevier B.V.
