Experimental models of orthotopic liver transplantation (OLT) have shown that the very early events post-OLT are critical in distinguishing immunogenic and tolerogenic reactions. In rodents, increased leukocyte apoptosis and cytokine expression have been demonstrated in tolerogenic strain combinations. Information from human OLT recipients is less abundant. The aim of this study was to determine the amount of early leukocyte activation and apoptosis following human OLT, and to correlate this with subsequent rejection status. Peripheral blood mononuclear cells (PBMC) were isolated from 76 patients undergoing OLT - on the day prior, 5 hrs after reperfusion (day 0), and 18-24 hrs post-OLT (day 1). The mean level of apoptotic PBMCs on post OLT day 1 was higher than healthy recipients (0.9% +/- 0.2 vs. 0.2% +/- 0.1, p = 0.013). Apoptosis was greater in nonrejecting (NR) (1.1% +/- 0.3) compared with acutely-rejecting (R) (0.3% +/- 0.1, p = 0.021) patients. On day 1, PBMC from NR patients had increased expression of IFN-gamma (p = 0.006), IL-10 (p = 0.016), and CD40 ligand (p = 0.02) compared with R. Donor cell chimerism on day 1 did not differ between the groups indicating that this was unlikely to account for increased PBMC apoptosis in the NR group. Interestingly, the level of chimerism on day 0 was significantly higher in NR (3.8% +/- 0.6) compared with R (1.2% +/- 0.4, p = 0.004) patients and there was a close correlation between chimerism on day 0 and cytokine expression on day 1. These results imply that similar mechanisms are occurring in the human liver to promote graft acceptance as in the experimental models of liver transplantation and suggest that strategies that promote liver transplant acceptance in rodents might be applicable to humans.

Edizione critica del volgarizzamento fiorentino trecentesco dell'"Estoire d'Eracles", contenuto nel ms. Plut. LXI.45 della Biblioteca Medicea Laurenziana, ancora inedito. Si tratta della traduzione in antico francese dell'opera di Guglielmo di Tiro "Historia rerum in partibus transamarinis gestarum", corredata di continuazioni svincolate all'opera latina e in stretto legame con la "Chronique d'Ernoul et de Bernard le Trésorier", che proseguono la narrazione degli eventi in Terrasanta. Il testo fiorentino riporta i fatti d'Oltremare dalla Prima Crociata a circa il 1231. La sua edizione è preceduta da una introduzione letterario-filologica, dalla descrizione del manoscritto e dall'analisi linguistica; seguono un glossario, l'indice dei nomi e dei luoghi.

Entre as traduções da Bíblia utilizadas nos países lusófonos, a clássica versão de João Ferreira de Almeida é a mais popular, mesmo quando o conceito de equivalência dinâmica é o impulsionador principal na produção de novas versões bíblicas. O texto da tradução original, tal como Almeida escreveu, jamais foi publicado e até agora não se conhece a localização de algum presumido manuscrito dela. As primeiras edições foram impressas com a revisão e aprovação do clero da Igreja Reformada Holandesa. Partindo do que se conhece da vida e da história da tradução de João Ferreira de Almeida, das seis primeiras edições do seu Novo Testamento e das edições do século XVIII do seu Antigo Testamento, esta pesquisa desenvolve um método para obtenção de uma edição crítica da obra de João Ferreira de Almeida, e o testa, produzindo uma versão crítica do Evangelho de Mateus.

Diante da pluralidade encontrada nas primeiras comunidades cristãs, a questão da divindade de Jesus é objeto de polêmicas. Os evangelhos sinóticos tratam a questão com certa discrição. Porém, o chamado Quarto Evangelho, traz uma revelação mais incisiva a respeito deste questionamento. Qual seria a razão para que a comunidade Joanina enfatizasse a divindade de Jesus? Há de se atentar para o fato de que conflitos com correntes diversas estivessem se fazendo presente na realidade de algumas comunidades, entre elas a de João, o que provavelmente levou a uma defesa mais contundente a respeito da questão. Pesquisas nos conduzem ao fato de que o Quarto Evangelho assinala a diversidade do cristianismo no I século e a realidade de um movimento que já estava se institucionalizando e se tornando fonte de poder não apenas religioso. A pericope de João 5. 19-30 revela uma evolução, por vezes confusa, no conceito da divindade de Jesus onde a terminologia filho se confunde com tradições judaicas e a figura dos filhos dos deuses presente no mundo antigo.

The ethnographic museum in the West has a long and troubling history. The display of 'exotic peoples' in travelling exhibitions began as early as the sixteenth century, but it was the mid and late nineteenth century that saw the great expansion of museums as sites to show artefacts collected - under anything but reputable circumstances - from what were considered the 'primitive', 'natural', or 'tribal' peoples of the world. Today the ethnographic museum is still a feature of large European cities, though faced with newly formulated dilemmas in the postcolonial world. For how can the material culture of a non-western people be collected and displayed in the West without its makers being translated into wordless and powerless objects of visual consumption? In national museums the processes of choosing, contextualizing and commentating exhibits help form national identity; in the ethnographic museum, similarly, they shape perceptions of the apparently distant Other. Like written ethnography, the museum is a 'translation of culture', with many of the associated problems traced by Talal Asad (1986). Like the written form, it has to represent the dialogic realities of cultural encounters in a fixed and intelligible form, to propose categories that define and order the material it has gathered. As the public face of academic ethnography, the museum interprets other cultures for the benefit of the general reader, and in that task museum practice, like all ethnography, operates within very specific historical and political parameters. How are museums in western Europe responding to the issues raised by critical ethnographers like James Clifford (1988), with their focus on the politics of representation? Is globalisation increasing the degree of accountability imposed on the ethnographic museum, or merely reinforcing older patterns? What opportunities and problems are raised by the use of more words - more 'translation' in the narrower sense - in ethnographic museums, and how do museums gain from introducing a reflexive and contextualizing concept of "thick translation" (Appiah 1993) into their work of interpretation?

Genetic interactions that underlie developmental processes such as cell differentiation and pattern formation are complex and difficult to elucidate. Neural Crest (NC) cells and their derivatives offer an optimal system in which to probe for these complex interactions as they acquire different cell fates and constitute a variety of structures. The transcription factors Sox10 and Pax3 as well as the transmembrane receptor Endothelin receptor b (Ednrb) are temporally and spatially co-expressed early in NC cells and mutations in these genes lead to similar hypopigmentation phenotypes due to a reduced number of NC-derived melanocyte precursors, the melanoblasts. The goal of this study was to establish whether Sox10 and Ednrb or Pax3 and Ednrb interact to promote normal murine melanocyte development. Crosses of Sox10 or Pax3 with Ednrb heterozygous mutants showed that the double heterozygous hypopigmentation phenotype was significantly more pronounced than phenotypes of single heterozygotes, implying that a synergistic interaction exists between Sox10 and Ednrb and Pax3 and Ednrb. This interaction was further explored by the attempt to rescue the Sox10 and Pax3 hypopigmentation phenotypes by the transgenic addition of Ednrb to melanoblasts. Pigmentation was completely restored in the Sox10 and partially restored in the Pax3 mutant mice. The comparison of the number of melanoblasts in transgenic and non-transgenic Sox10 mutant embryos showed that the transgenic rescue occurred as early as E11.5, a critical time for melanoblast population expansion. Cell survival assays indicated that the rescue was not due to an effect of the transgene on melanoblast survival. A novel phenotype arose when studying the interaction between Ednrb and Pax3. Newborns appeared normal but by 3.5 weeks of age, the affected pups were smaller than normal littermates and developed a dome-shaped head; some also developed thoracic kyphosis. Affected pups were dead by 4 weeks of age: 80% were Pax3Sp/+ and 75% were female. When compared to normal littermates, affected mice had brains with enlarged 4th ventricles and more glia while skeletal staining showed kyphosis, wider rib cages and pelvic differences. An epistatic interaction resulting from the mixing of genetic backgrounds that is exacerbated in the presence of Pax3 heterozygosity is suspected.
