Abstract3′ untranslated regions (3′ UTRs) of mRNAs have many functions, including mRNA processing and transport, translational regulation, and mRNA degradation and stability. These different functions require cis‐elements in 3′ UTRs that can be either sequence motifs or RNA structures. Here we review the role of secondary structures in the functioning of 3′ UTRs and discuss some of the trans‐acting factors that interact with these secondary structures in eukaryotic organisms. We propose potential participation of 3′‐UTR secondary structures in cytoplasmic polyadenylation in (...) the model organism Drosophila melanogaster. Because the secondary structures of 3′ UTRs are essential for post‐transcriptional regulation of gene expression, their disruption leads to a wide range of disorders, including cancer and cardiovascular diseases. Trans‐acting factors, such as STAU1 and nucleolin, which interact with 3′‐UTR secondary structures of target transcripts, influence the pathogenesis of neurodegenerative diseases and tumor metastasis, suggesting that they are possible therapeutic targets.

L'actualité des Chiens de garde, nous aurions préféré ne pas en éprouver la robuste fraîcheur. Nous aurions aimé qu'un même côté de la barricade cessât de réunir penseurs de métier et bâtisseurs de ruines. Nous aurions voulu que la dissidence fût devenue à ce point contagieuse que l'invocation de Nizan au sursaut et à la résistance en parût presque inutile. Car nous continuons à vouloir un autre monde. L'entreprise nous dépasse? Notre insuffisance épuise notre persévérance? Souvenons-nous alors de ce passage (...) par lequel Sartre a résumé l'appel aux armes de son vieux camarade : "Il peut dire aux uns : vous mourez de modestie, osez désirer, soyez insatiables, ne rougissez pas de vouloir la lune : il nous la faut. Et aux autres : dirigez votre rage sur ceux qui l'ont provoquée, n'essayez pas d'échapper à votre mal, cherchez ses causes et cassez-les." Serge Hamili Extrait de la préface. (shrink)

In this work, Paul Weithman offers a fresh, rigorous and compelling interpretation of John Rawls' reasons for taking his so-called 'political turn'.

Paul M. Pietroski presents an ambitious new account of human languages as generative procedures that respect substantive constraints. He argues that meanings are neither concepts nor extensions, and sentences do not have truth conditions; meanings are composable instructions for how to access and assemble concepts of a special sort.

Cuando ahora las formas de hacer historia materializan una multiplicidad de grafías, y el giro reflexivo y el giro historiográfico nos permiten idear las historias de las teorías de la historia en una posibilidad más, en este ensayo se presenta un deseo, una promesa cuya llave de acceso precisa saber lo que pretende la locución arqueoescritura. Esbozos y trazas de la teoría de la historia en cuestión: ¿qué cabe esperar en las escrituras diferidas de la arqueoescritura? Escrituras equívocas en clave (...) derridiana de la teoría de la historia como historiografía. Una posibilidad imposible aplazada. Escrituras para examinar la metafísica de la presencia en la historiografía, conscientes de que no podrán formular una teoría de la historia en la única firma derridiana, porque lo real se resiste a ser domado e incorporado al impar filosófico derridiano.

In a belief ascription like ‘Sam believes that Hesperus rises in the evening’, the complementizer ‘that’ is a device for referring to the sense of the embedded sentence. On this Fregean view, substitutivity of co‐referential terms need not preserve truth. This accounts for the opacity of propositional attitude ascriptions, while preserving what Davidson called semantic innocence.

The proposed account of causation, in terms of explanation, does not sleight the mind‐independence of causal relations. The relevant notion of explanation is objective, even if facts are taken to be abstract Fregean ‘modes of presenting’ events. Causation remains a natural, and often perceptible relation between spatiotemporal particulars. But we must resist empiricist conceptions of causation.

An updated version of Plato's Dialogues, this adaptation takes place in contemporary times and is set at Reed College in Portland, Oregon. Through the characters' central discussions of Creationist and Materialist theories of evolution, together with their moral and social implications and ramifications, the author defines philosophy and science. This fresh approach to complex philosophical subjects will be an interesting supplement to courses in philosophy.
