Décliner la frontière : transit et contagion de la violence dans la fiction sacrificielle de Bernard-Marie Koltès

Ce mémoire de maîtrise traite de quatre pièces de l’auteur français Bernard-Marie Koltès. Résolument axé sur l’étude du texte écrit, il vise dans un premier temps l’analyse d’un ensemble de désajustements et d’une culture de l’équivoque dans le traitement du lieu, du temps et de l’identité. Le premier but de ces analyses est l’approfondissement de certaines avenues déjà investies par la critique (marginalité des lieux et des personnages, présence constante de la violence et de la mort, etc.), dans la recherche d’une signification globale à un ensemble de pratiques textuelles liées à la notion de limite ou de frontière. Opérant un changement de perspective, la seconde partie de l’étude s’attarde à la violence ainsi qu’aux modalités et implications de sa mise en texte dans une étude croisée de l’acte créateur et de la pratique de lecture. À partir de la théorie du sacrifice élaborée par René Girard dans La violence et le sacré, et faisant dialoguer certains textes importants d’auteurs divers (Aristote, Nietzsche, Artaud, Foucault, Derrida et Adorno), l’analyse vise à inscrire la littérarité du texte koltésien dans une entreprise plus vaste ayant à voir avec la violence, sa régulation et sa diffusion. Au carrefour des études théâtrales, de la littérature et de la philosophie, cette réflexion cherche à concevoir le théâtre de Koltès (particulièrement Roberto Zucco) comme un sacrifice rituel, afin de mieux en comprendre le rapport au réel et certaines de ses particularités du point de vue du mécanisme cathartique.

El ser y el parecer en Thérèse Desqueyroux.

El personaje de una novela tiene el papel principal, organizándose los demás elementos de la narración a partir de él. Existen tres clases de relaciones posibles entre los personajes: amor, comunicación y ayuda. Pero no olvidemos una relación que está presente en estas tres, es la relación del ser y del parecer. En efecto cada acción puede parecer a primera vista amor, confidencia, para revelarse luego como otra relación: odio, oposición..La apariencia no coincide necesariamente con la esencia de la relación. La existencia de estos dos niveles destaca claramente en la novela de François Mauriac, Thérèse Desqueyroux. La heroína se relaciona con los principales personajes (Anne, Bernard, Marie, Jean) de la novela y tratar de ver si otro elemento de la narración, el léxico coinciden con estos niveles del ser y del parecer. En definitiva, analizando las relaciones de Teresa con los principales personajes de la novela hemos constatado los dos niveles, el ser y el parecer. En este último nivel abunda todo un léxico referente a la mentira. El campo de la verdad es menor, lo que prueba la importancia de la mentira en esta novela y plena coincidencia del elemento lexicográfico con las relaciones del personaje principal.

Traverser l'immobile : le déplacement dans le Journal de Marie Uguay

Ce mémoire s’intéresse au Journal de la poète québécoise Marie Uguay et analyse comment la thématique du mouvement y engendre un rapport sensible aux lieux. Il s’appuie notamment sur les travaux sur l’espace de Pierre Nepveu et sur les théories contemporaines du paysage. La condition physique de Uguay, atteinte d’un cancer des os, détermine une manière particulière d’appréhender l’espace, au travers d’une écriture portée vers l’intime. Le premier chapitre est consacré à la dialectique entre intérieur et extérieur, l’écrivaine imaginant de nombreux voyages à partir de la réclusion de son appartement montréalais. Le deuxième chapitre porte sur les lieux effectivement parcourus. Finalement, le troisième chapitre explore une lecture similaire de l’espace chez les poètes Hector de Saint-Denys Garneau et Albert Lozeau, qui peut permettre d’établir une filiation intellectuelle entre eux et la diariste. Il examine également comment la reprise de la figure de Marie Uguay dans la littérature contemporaine tient compte d’une relation particulière à l’espace.

An ARHGEF10 deletion is highly associated with a juvenile-onset inherited polyneuropathy in Leonberger and Saint Bernard dogs

An inherited polyneuropathy (PN) observed in Leonberger dogs has clinical similarities to a genetically heterogeneous group of peripheral neuropathies termed Charcot-Marie-Tooth (CMT) disease in humans. The Leonberger disorder is a severe, juvenile-onset, chronic, progressive, and mixed PN, characterized by exercise intolerance, gait abnormalities and muscle atrophy of the pelvic limbs, as well as inspiratory stridor and dyspnea. We mapped a PN locus in Leonbergers to a 250 kb region on canine chromosome 16 (Praw = 1.16×10-10, Pgenome, corrected = 0.006) utilizing a high-density SNP array. Within this interval is the ARHGEF10 gene, a member of the rho family of GTPases known to be involved in neuronal growth and axonal migration, and implicated in human hypomyelination. ARHGEF10 sequencing identified a 10 bp deletion in affected dogs that removes four nucleotides from the 3'-end of exon 17 and six nucleotides from the 5'-end of intron 17 (c.1955_1958+6delCACGGTGAGC). This eliminates the 3'-splice junction of exon 17, creates an alternate splice site immediately downstream in which the processed mRNA contains a frame shift, and generates a premature stop codon predicted to truncate approximately 50% of the protein. Homozygosity for the deletion was highly associated with the severe juvenile-onset PN phenotype in both Leonberger and Saint Bernard dogs. The overall clinical picture of PN in these breeds, and the effects of sex and heterozygosity of the ARHGEF10 deletion, are less clear due to the likely presence of other forms of PN with variable ages of onset and severity of clinical signs. This is the first documented severe polyneuropathy associated with a mutation in ARHGEF10 in any species.

Celebrating difference/censoring difference? : Marie Chouinard’s bODY rEMIX

This paper examines performances that defy established representations of disease, deformity and bodily difference. Historically, the ‘deformed’ body has been cast – onstage and in sideshows – as flawed, an object of pity, or an example of the human capacity to overcome. Such representations define the boundaries of the ‘normal’ body by displaying its Other. They bracket the ‘abnormal’ body off as an example of deviance from the ‘norm’, thus, paradoxically, decreasing the social and symbolic visibility (and agency) of disabled people. Yet, in contemporary theory and culture, these representations are reappropriated – by disabled artists, certainly, but also as what Carrie Sandahl has called a ‘master trope’ for representing a range of bodily differences. In this paper, I investigate this phenomenon. I analyse French Canadian choreographer Marie Chouinard’s bODY rEMIX/gOLDBERG vARIATIONS, in which 10 able-bodied dancers are reborn as bizarre biotechnical mutants via the use of crutches, walkers, ballet shoes and barres as prosthetic pseudo-organs. These bodies defy boundaries, defy expectations, develop new modes of expression, and celebrate bodily difference. The self-inflicted pain dancers experience during training is cast as a ‘disablement’ that is ultimately ‘enabling’. I ask what effect encountering able bodies celebrating ‘dis’ or ‘diff’ ability has on audiences. Do we see the emergence of a once-repressed Other, no longer silenced, censored or negated? Or does using ‘disability’ to express the dancers’ difference and self-determination usurp a ‘trope’ by which disabled people themselves might speak back to the dominant culture, creating further censorship?

A dominant-negative mutation in the TRESK potassium channel is linked to familial migraine with aura

Migraine with aura is a common, debilitating, recurrent headache disorder associated with transient and reversible focal neurological symptoms. A role has been suggested for the two-pore domain (K2P) potassium channel, TWIK-related spinal cord potassium channel (TRESK, encoded by KCNK18), in pain pathways and general anaesthesia. We therefore examined whether TRESK is involved in migraine by screening the KCNK18 gene in subjects diagnosed with migraine. Here we report a frameshift mutation, F139WfsX24, which segregates perfectly with typical migraine with aura in a large pedigree. We also identified prominent TRESK expression in migraine-salient areas such as the trigeminal ganglion. Functional characterization of this mutation demonstrates that it causes a complete loss of TRESK function and that the mutant subunit suppresses wild-type channel function through a dominant-negative effect, thus explaining the dominant penetrance of this allele. These results therefore support a role for TRESK in the pathogenesis of typical migraine with aura and further support the role of this channel as a potential therapeutic target.

Regional chromosomal assignment of human renin gene to 1q12→qter and use in linkage studies in Charcot-Marie-Tooth disease

The gene for renin, previously mapped to human chromosome 1, was further localized to 1q12 → qter using human-mouse somatic cell hybrid DNAs. The renin DNA probe used (λ HR5) could detect a HindIII restriction fragment length polymorphism. When used in studies of 12 informative families, no linkage could be found between the renin and Charcot-Marie-Tooth disease. Furthermore, an association of any renin allele with hypertension was not apparent.

Chromosome I linkage studies in Charcot-Marie-Tooth neuropathy type I

Charcot-Marie-Tooth neuropathy type 1 (CMT1) is an autosomal dominant disorder of peripheral nerve. The gene for CMT1 was originally localized to chromosome 1 by linkage to the Duffy blood group, but it has since been shown that not all CMT1 pedigrees show this linkage. We report here the results of linkage studies using five chromosome 1 markers - Duffy (Fy), antithrombin III (AT3), renin (REN), β-nerve growth factor (NGFB), and salivary amylase (AMY1) - in 16 CMT1 pedigrees. The total lod scores exclude close linkage of CMT1 to any of these markers. However, individual families show probable linkage of CMT1 to Duffy, AT3, and/or AMY1. No linkage was indicated with REN or NGFB. These results indicate that possible location of a CMT1 gene between the AMY1 and AT3 loci at p21 and q23, respectively, on chromosome 1 and support the theory that there is at least one other CMT1 gene.

Heterogeneity evidence and linkage studies on Charcot-Marie-Tooth disease

Charcot-Marie-Tooth neuropathy type 1 (CMT1) is an autosomal dominant disorder originally localized to chromosome 1 by linkage to the Duffy blood group. Studies have since shown that the disorder may be heterogeneous, as not all families show this linkage. We tested genetic heterogeneity by the HOMOG computer program in 15 CMT1 pedigrees informative for Duffy. We detected no evidence for heterogeneity in this sample, but when we combined results with previously published lod scores, heterogeneity was statistically significant. Twelve of the 15 families studied did not show linkage to Duffy. We found six of these families to be informative for a chromosome 19 marker, apolipoprotein CII(ApoC2). Despite a previous report showing probable linkage of a non-Duffy-linked CMT1 pedigree to two chromosome 19 markers, we did not detect significant linkage of ApoC2 to CMT1 in these families.

Isolation and use of chromosome 1 probes for linkage studies on Charcot-Marie-Tooth disease

Nine probes were isolated from a human chromosome 1 enriched library and mapped to regions of chromosome 1 using somatic cell hybrid lines. One clone, LR67, which mapped 1q12→q23 detected a BglI RFLP. This probe, as well as 4 other known chromosome 1 markers, α-spectrin, Factor XIIIB, DR10 and DR78, were used for linkage studies in 15 Charcot-Marie-Tooth disease (CMT1) families. Close linking of CMT1 to any of the 5 markers was not indicated. Total lod scores excluded linkage of CMT1 to LR67 and to DR10 at 5 cM or less, to DR78 and 10 cM or less, α-spectrin at 15 cM or less and Factor XIIIB at 20 cM or less. Possible linkage, however, was shown between LR67 and CMT1 at a distance of 30 cM. Also linkage at a distance of 5 cM was detected between this probe and α-spectrin.

DNA probes in Charcot-Marie-Tooth neuropathy

Results of Duffy (Fy) linkage confirm genetic heterogeneity in Charcot-Marie-Tooth disease type 1 (CMT1). Of 11 families informative for Fy, four showed probable linkage with CMT1, seven showed probable non-linkage and two showed definite non-linkage. These results suggest that Fy linked CMT1 may be less common than previously thought. These results combined with those of another DNA probe for the antithrombin III gene confirm that there are at least two gene loci for CMT1, termed 1A and 1B.
