Resumo Concepções e rituais associados à morte ocupam uma importante dimensão nas diferentes construções da tradição islâmica, criando não apenas sentido/orientação a respeito do fim inevitável da vida física, mas também canais para afirmação pública de crenças e pertencimentos religiosos para muçulmanos em diferentes contextos históricos e culturais. Seguindo nesta direção, o artigo pretende abordar concepções e práticas associadas à morte no islã, tendo como foco os rituais de preparação e o destino final do corpo do morto. O universo etnográfico em que esta pesquisa se baseia compreende as comunidades muçulmanas do Rio de Janeiro e Paraná, em diferentes momentos de trabalho de campo (2012 a 2014). Com isso, espera-se explorar como objetos e espaços funerários fazem o “morto muçulmano” em contextos nos quais o islã ocupa uma posição de minoria religiosa, como no Brasil.

Acute renal failure (ARF) is a frequent complication of Gram-negative sepsis, with a high risk of mortality. Lipopolysaccharide (LPS)-induced ARF is associated with hemodynamic changes that are strongly influenced by the overproduction of nitric oxide (NO) through the cytokine-mediated up-regulation of inducible NO synthase. LPS-induced reductions in systemic vascular resistance paradoxically culminate in renal vasoconstriction. Collagen XVIII is an important component of the extracellular matrix expressed in basement membranes. Its degradation by matrix metalloproteases, cathepsins and elastases results in the formation of endostatin, claimed to have antiangiogenic activity and to be a prominent vasorelaxing agent. We evaluated the expression of endostatin/collagen XVIII in an endotoxemic ARF model. ARF was induced in C57BL/6 mice by intraperitoneal injection of LPS (10 mg/kg) followed by sacrifice 4 and 12 h later. Kidney tissue was the source of RNA and protein and the subject of histological analysis. As early as 4 h after LPS administration, blood urea, creatinine and NO levels were significantly increased compared to control. Endostatin/collagen XVIII mRNA levels were 0.71 times lower than sham-inoculated mice 4 h after LPS inoculation, returning to normal levels 12 h after LPS inoculation. Immunohistological examination revealed that acute injury caused by LPS leads to an increase of endostatin basement membrane staining in association with the decrease of CD31 endothelial basement membrane staining. These results indicate that in the early phase of endotoxemic ARF the endostatin levels were not regulated by gene expression, but by the metabolism of collagen XVIII.
