Criminal Conversations: Rogues, Words and the World in the Work of Daniel Defoe

Even as Daniel Defoe's roguish protagonists notably Moll Flanders and Colonel Jack try to separate themselves from illicit itinerants, they are implicated further in deviance. Moll and Jack both embody and exploit ambiguous moral and spatial arrangements, and use hybrid linguistic formulations, all of which collocate the roguish and the reputable. By brilliantly realizing this interpenetration of words and worlds, Defoe problematises eighteenth-century efforts to demarcate the illicit and itinerant along the lines of space, rank, gender and language. Such efforts facilitated deviant mobility as much as they demonised it. Much scholarship has attended to Defoe's representations of criminality and poverty. This article develops such research to re-position him in a tradition of rogue-writing that stylishly problematises normative discriminatory practices.

The Afroporteña press and Afro-Argentine’s thought in the late nineteenth century

The journalistic boom that occurred in Argentina from the second half of the nineteenth century saw the emergence of an active afroporteña press that defend the interests of the black community. This paper, in addition to reviewing the history of the Afro-Argentines newspapers, emphasizes the role played by the elite of African descent in the promotion of modernity among his brothers, while exploring the possible bases for an identity in the ideas spread.

Chemotherapy and TRAIL-mediated colon cancer cell death: the roles of p53, TRAIL receptors, and c-FLIP.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has recently attracted attention as a potential therapeutic agent in the treatment of cancer. We assessed the roles of p53, TRAIL receptors, and cellular Fas-associated death domain-like interleukin-1beta-converting enzyme inhibitory protein (c-FLIP) in regulating the cytotoxic effects of recombinant TRAIL (rTRAIL) alone and in combination with chemotherapy [5-fluorouracil (5-FU), oxaliplatin, and irinotecan] in a panel of colon cancer cell lines. Using clonogenic survival and flow cytometric analyses, we showed that chemotherapy sensitized p53 wild-type, mutant, and null cell lines to TRAIL-mediated apoptosis. Although chemotherapy treatment did not modulate mRNA or cell surface expression of the TRAIL receptors death receptor 4, death receptor 5, decoy receptor 1, or decoy receptor 2, it was found to down-regulate expression of the caspase-8 inhibitor, c-FLIP. Stable overexpression of the long c-FLIP splice form but not the short form was found to inhibit chemotherapy/rTRAIL-induced apoptosis. Furthermore, siRNA-mediated down-regulation of c-FLIP, particularly the long form, was found to sensitize colon cancer cells to rTRAIL-induced apoptosis. In addition, treatment of a 5-FU-resistant cell line with 5-FU down-regulated c-FLIP expression and sensitized the chemotherapy-resistant cell line to rTRAIL. We conclude that TRAIL-targeted therapies may be used to enhance conventional chemotherapy regimens in colon cancer regardless of tumor p53 status. Furthermore, inhibition of c-FLIP may be a vital accessory strategy for the optimal use of TRAIL-targeted therapies.
