Dissecting the genetic heterogeneity of depression through age at onset.

Genome-wide studies in major depression have identified few replicated associations, potentially due to heterogeneity within the disorder. Several studies have suggested that age at onset (AAO) can distinguish sub-types of depression with specific heritable components. This paper investigates the role of AAO in the genetic susceptibility for depression using genome-wide association data on 2,746 cases and 1,594 screened controls from the RADIANT studies, with replication performed in 1,471 cases and 1,403 controls from two Munich studies. Three methods were used to analyze AAO: First a time-to-event analysis with controls censored, secondly comparing controls to case-subsets defined using AAO cut-offs, and lastly analyzing AAO as a quantitative trait. In the time-to-event analysis three SNPs reached suggestive significance (P&#8201;<&#8201;5E-06), overlapping with the original case-control analysis of this study. In a case-control analysis using AAO thresholds, SNPs in 10 genomic regions showed suggestive association though again none reached genome-wide significance. Lastly, case-only analysis of AAO as a quantitative trait resulted in 5 SNPs reaching suggestive significance. Sex specific analysis was performed as a secondary analysis, yielding one SNP reaching genome-wide significance in early-onset males. No SNPs achieved significance in the replication study after correction for multiple testing. Analysis of AAO as a quantitative trait did suggest that, across all SNPs, common genetic variants explained a large proportion of the variance (51%, P&#8201;=&#8201;0.04). This study provides the first focussed analysis of the genetic contribution to AAO in depression, and establishes a statistical framework that can be applied to a quantitative trait underlying any disorder. © 2012 Wiley Periodicals, Inc.

A genome-wide association study of anorexia nervosa.

Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14&#8201;860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3). Individual association analyses were conducted in each stratum and meta-analyzed across all 15 discovery data sets. Seventy-six (72 independent) single nucleotide polymorphisms were taken forward for in silico (two data sets) or de novo (13 data sets) replication genotyping in 2677 independent AN cases and 8629 European ancestry controls along with 458 AN cases and 421 controls from Japan. The final global meta-analysis across discovery and replication data sets comprised 5551 AN cases and 21&#8201;080 controls. AN subtype analyses (1606 AN restricting; 1445 AN binge-purge) were performed. No findings reached genome-wide significance. Two intronic variants were suggestively associated: rs9839776 (P=3.01 × 10(-7)) in SOX2OT and rs17030795 (P=5.84 × 10(-6)) in PPP3CA. Two additional signals were specific to Europeans: rs1523921 (P=5.76 × 10(-)(6)) between CUL3 and FAM124B and rs1886797 (P=8.05 × 10(-)(6)) near SPATA13. Comparing discovery with replication results, 76% of the effects were in the same direction, an observation highly unlikely to be due to chance (P=4 × 10(-6)), strongly suggesting that true findings exist but our sample, the largest yet reported, was underpowered for their detection. The accrual of large genotyped AN case-control samples should be an immediate priority for the field.

The Criminal Justice Approach : Case Exemples

This article provides an overview of the various forms of proceedings available within 11 European criminal justice systems and reflects upon their core features. It also provides a picture of how far alternative, non-criminal proceedings are used by some of the systems as a different path to imposing a state reaction upon wrong-doers.

A genetic risk score combining 32 SNPs is associated with body mass index and improves obesity prediction in people with major depressive disorder.

BACKGROUND: Obesity is strongly associated with major depressive disorder (MDD) and various other diseases. Genome-wide association studies have identified multiple risk loci robustly associated with body mass index (BMI). In this study, we aimed to investigate whether a genetic risk score (GRS) combining multiple BMI risk loci might have utility in prediction of obesity in patients with MDD. METHODS: Linear and logistic regression models were conducted to predict BMI and obesity, respectively, in three independent large case-control studies of major depression (Radiant, GSK-Munich, PsyCoLaus). The analyses were first performed in the whole sample and then separately in depressed cases and controls. An unweighted GRS was calculated by summation of the number of risk alleles. A weighted GRS was calculated as the sum of risk alleles at each locus multiplied by their effect sizes. Receiver operating characteristic (ROC) analysis was used to compare the discriminatory ability of predictors of obesity. RESULTS: In the discovery phase, a total of 2,521 participants (1,895 depressed patients and 626 controls) were included from the Radiant study. Both unweighted and weighted GRS were highly associated with BMI (P <0.001) but explained only a modest amount of variance. Adding 'traditional' risk factors to GRS significantly improved the predictive ability with the area under the curve (AUC) in the ROC analysis, increasing from 0.58 to 0.66 (95% CI, 0.62-0.68; &#967;(2)&#8201;=&#8201;27.68; P <0.0001). Although there was no formal evidence of interaction between depression status and GRS, there was further improvement in AUC in the ROC analysis when depression status was added to the model (AUC&#8201;=&#8201;0.71; 95% CI, 0.68-0.73; &#967;(2)&#8201;=&#8201;28.64; P <0.0001). We further found that the GRS accounted for more variance of BMI in depressed patients than in healthy controls. Again, GRS discriminated obesity better in depressed patients compared to healthy controls. We later replicated these analyses in two independent samples (GSK-Munich and PsyCoLaus) and found similar results. CONCLUSIONS: A GRS proved to be a highly significant predictor of obesity in people with MDD but accounted for only modest amount of variance. Nevertheless, as more risk loci are identified, combining a GRS approach with information on non-genetic risk factors could become a useful strategy in identifying MDD patients at higher risk of developing obesity.

Points to consider for prioritizing clinical genetic testing services: a European consensus process oriented at accountability for reasonableness.

Given the cost constraints of the European health-care systems, criteria are needed to decide which genetic services to fund from the public budgets, if not all can be covered. To ensure that high-priority services are available equitably within and across the European countries, a shared set of prioritization criteria would be desirable. A decision process following the accountability for reasonableness framework was undertaken, including a multidisciplinary EuroGentest/PPPC-ESHG workshop to develop shared prioritization criteria. Resources are currently too limited to fund all the beneficial genetic testing services available in the next decade. Ethically and economically reflected prioritization criteria are needed. Prioritization should be based on considerations of medical benefit, health need and costs. Medical benefit includes evidence of benefit in terms of clinical benefit, benefit of information for important life decisions, benefit for other people apart from the person tested and the patient-specific likelihood of being affected by the condition tested for. It may be subject to a finite time window. Health need includes the severity of the condition tested for and its progression at the time of testing. Further discussion and better evidence is needed before clearly defined recommendations can be made or a prioritization algorithm proposed. To our knowledge, this is the first time a clinical society has initiated a decision process about health-care prioritization on a European level, following the principles of accountability for reasonableness. We provide points to consider to stimulate this debate across the EU and to serve as a reference for improving patient management.

Relationship between obesity and the risk of clinically significant depression: Mendelian randomisation study.

BACKGROUND: Obesity has been shown to be associated with depression and it has been suggested that higher body mass index (BMI) increases the risk of depression and other common mental disorders. However, the causal relationship remains unclear and Mendelian randomisation, a form of instrumental variable analysis, has recently been employed to attempt to resolve this issue. AIMS: To investigate whether higher BMI increases the risk of major depression. METHOD: Two instrumental variable analyses were conducted to test the causal relationship between obesity and major depression in RADIANT, a large case-control study of major depression. We used a single nucleotide polymorphism (SNP) in FTO and a genetic risk score (GRS) based on 32 SNPs with well-established associations with BMI. RESULTS: Linear regression analysis, as expected, showed that individuals carrying more risk alleles of FTO or having higher score of GRS had a higher BMI. Probit regression suggested that higher BMI is associated with increased risk of major depression. However, our two instrumental variable analyses did not support a causal relationship between higher BMI and major depression (FTO genotype: coefficient -0.03, 95% CI -0.18 to 0.13, P = 0.73; GRS: coefficient -0.02, 95% CI -0.11 to 0.07, P = 0.62). CONCLUSIONS: Our instrumental variable analyses did not support a causal relationship between higher BMI and major depression. The positive associations of higher BMI with major depression in probit regression analyses might be explained by reverse causality and/or residual confounding.

Cinéastes indépendants, politique fédérale du cinéma et co-production du 'Nouveau cinéma suisse', 1963-1970. Contribution à une sociologie de l'innovation artistique

Ce travail s'intéresse aux modalités d'émergence et d'institutionnalisation d'un nouveau régime de création artistique, plus connu sous le nom de «Nouveau cinéma suisse ».Dans les années 1960-1970, l'arrivée du Nouveau cinéma suisse a bouleversé les manières de faire du cinéma en Suisse et a attiré l'attention sur le septième art helvétique. Comment une innovation artistique parvient-elle à s'imposer ? Comment un consensus autour d'une nouvelle forme artistique et de son mode de production émerge et se stabilise-t-il ? Quel rôle jouent les acteurs et les institutions dans ce processus ? Enfin, quelles sont les relations entre cette situation en devenir et les oeuvres créées dans ces conditions ? Au delà dé ces interrogations, c'est un questionnement théorique, épistémologique qui a motivé cette recherche. A l'image de la sociologie elle-même, l'analyse sociologique de l'art a été traversée, ces dernières années, pas de nombreux débats. Trop souvent, la réflexion s'appuie - ou trébuche -sur des dichotomies convenues :analyse interne /externe de l'art, déterminisme /indétermination des acteurs, reflet /autonomie des oeuvres. Quels sont les outils et les approches que propose la discipline pour analyser un tel objet, quels enseignements peut-on titrer de leur mise à l'épreuve sur un cas concret ? Quel est le défi lancé par le Nouveau cinéma suisse à la sociologie de l'art ?Mais commençons par le début car le point initial de cette longue entreprise était en réalité tout autre.

La pseudo-clivée: étude en linguistique interactionnelle

2. Plan du travail Pour atteindre nos objectifs, notre travail sera essentiellement divisé en trois grandes sections. La première partie nous sert principalement à esquisser notre démarche et les enjeux de notre entreprise, ainsi qu'à la situer au sein d'un cadre théorique - la linguistique interactionnelle - combinant l'analyse grammaticale et l'analyse conversationnelle. Nous procéderons d'abord à une brève description de l'analyse conversationnelle ethnométhodologique, ensuite à celle du courant Interaction and Grammar. Dans le cadre de ces descriptions, nous illustrerons par des exemples les liens entre la grammaire et l'interaction sociale tels qu'ils ont été élaborés dans de nombreuses recherches dans le domaine. Finalement, nous résumerons nos objectifs et nos procédures d'analyse. La deuxième partie consiste essentiellement en une discussion et une problématisation de l'état de la recherche dans la littérature. L'exposé montrera les principaux problèmes que la pseudo-clivée pose aux différents niveaux d'analyse. Nous y traiterons des problèmes de définition et de délimitation de la construction en question au niveau syntaxique et sémantique. Nous enchaînerons avec l'exposé de l'état de la recherche au niveau pragmatique et discursif Cette discussion nous permettra de problématiser à la fois la fonction principale dévolue à la pseudo-clivée et l'établissement de la relation entre forme et fonction. Finalement, nous aborderons certains aspects dont nous ne nous occuperons pas ou seulement partiellement dans notre travail. Le résumé de cette deuxième partie nous servira à récapituler les problèmes soulevés par la pseudo-clivée française. La troisième partie - empirique et analytique - constitue la partie centrale de ce travail. Elle exposera nos résultats à travers l'analyse d'exemples qui exhibent les propriétés typiques des occurrences retenues dans notre corpus. Cette partie est donc consacrée aux formes, aux fonctionnements syntaxico-séquentiels et aux fonctions effectivement rencontrées dans nos données pour aboutir à une description de ses propriétés interactives et à une typologie compatible avec les usages interactifs réels. Après l'exposé de ce qui nous semble le plus typique dans l'usage interactif effectif de la pseudo-clivée par les interlocuteurs, nous nous dirigerons plus particulièrement vers la délimitation et la localisation de notre objet d'analyse, d'une part, par rapport à d'autres constructions (clivées, pseudo-clivées inversées, dislocations à gauche), et d'autre part, par rapport à d'autres unions d'unités qui n'ont pas le statut de construction en usage. Finalement, nous tenterons d'intégrer nos observations dans une description cohérente du "phénomène pseudo-clivé" dans l'usage des locuteurs. De plus, nous présenterons - sur la base de nos résultats - des réponses ou des éléments de réponse aux problématiques soulevées par notre objet d'analyse telles que nous les avons élaborées et discutées dans la partie II de ce travail. Nous terminerons par une discussion sur les apports de notre démarche, ainsi qu'à une évaluation de notre conception spécifique des faits de grammaire, et plus particulièrement d'une construction syntaxique (partie IV). Nous indiquerons des pistes de recherche possibles à suivre en fonction de nos résultats. Parmi d'éventuelles investigations futures, un accent particulier sera mis sur les aspects prosodiques et la recherche comparative.

From Naples 1963 to Rome 2013 - A brief review of how the International Research Group on Ostracoda (IRGO) developed as a social communication system

The 1st International Symposium on Ostracoda (ISO) was held in Naples (1963). The philosophy behind this symposium and the logical outcome of what is now known as the International Research Group on Ostracoda (IRGO) is here reviewed, namely ostracodology over the last 50 years is sociologically analysed. Three different and important historic moments for the scientific achievements of this domain are recognised. The first one, between about 1963-1983, is related to applied research for the oil industry as well as to the great interest in the better description of the marine environment by both zoologists and palaeontologists. Another important aspect during this period was the work by researchers dealing with Palaeozoic ostracods, who had their own discussion group, IRGPO. Gradually, the merger of this latter group with those dealing with post-Palaeozoic ostracods at various meetings improved communication between the two groups of specialists. A second period was approximately delineated between 1983 and 2003. During this time-slice, more emphasis was addressed to environmental research with topics such as the study of global events and long-term climate change. Ostracodologists profited also from the research "politics" within national and international programmes. Large international research teams emerged using new research methods. During the third period (2003-2013), communication and collaborative research reached a global dimension. Amongst the topics of research we cite the reconstruction of palaeoclimate using transfer functions, the building of large datasets of ostracod distributions for regional and intercontinental studies, and the implementation of actions that should lead to taxonomic harmonisation. Projects within which molecular biological techniques are routinely used, combined with sophisticated morphological information, expanded now in their importance. The documentation of the ostracod description improved through new techniques to visualise morphological details, which stimulated also communication between ostracodologists. Efforts of making available ostracod information through newsletters and electronic media are evoked.

Ocular and systemic bio-distribution of rhodamine-conjugated liposomes loaded with VIP injected into the vitreous of Lewis rats.

PURPOSE: Local delivery of therapeutic molecules encapsulated within liposomes is a promising method to treat ocular inflammation. The purpose of the present study was to define the biodistribution of rhodamine-conjugated liposomes loaded with vasoactive intestinal peptide (VIP), an immunosuppressive neuropeptide, following their intravitreal (IVT) injection in normal rats. METHODS: Healthy seven- to eight-week-old Lewis male rats were injected into the vitreous with empty rhodamine-conjugated liposomes (Rh-Lip) or with VIP-loaded Rh-Lip (VIP-Rh-Lip; 50 mM of lipids with an encapsulation efficiency of 3.0+/-0.4 mmol VIP/mol lipids). Twenty-four h after IVT injection, the eyes, the cervical, mesenteric, and inguinal lymph nodes (LN), and spleen were collected. The phenotype and distribution of cells internalizing Rh-Lip and VIP-Rh-Lip were studied. Determination of VIP expression in ocular tissues and lymphoid organs and interactions with T cells in cervical LN was performed on whole mounted tissues and frozen tissue sections by immunofluorescence and confocal microscopy. RESULTS: In the eye, 24 h following IVT injection, fluorescent liposomes (Rh-Lip and VIP-Rh-Lip) were detected mainly in the posterior segment of the eye (vitreous, inner layer of the retina) and to a lesser extent at the level of the iris root and ciliary body. Liposomes were internalized by activated retinal Müller glial cells, ocular tissue resident macrophages, and rare infiltrating activated macrophages. In addition, fluorescent liposomes were found in the episclera and conjunctiva where free VIP expression was also detected. In lymphoid organs, Rh-Lip and VIP-Rh-Lip were distributed almost exclusively in the cervical lymph nodes (LN) with only a few Rh-Lip-positive cells detected in the spleen and mesenteric LN and none in the inguinal LN. In the cervical LN, Rh-Lip were internalized by resident ED3-positive macrophages adjacent to CD4 and CD8-positive T lymphocytes. Some of these T lymphocytes in close contact with macrophages containing VIP-Rh-Lip expressed VIP. CONCLUSIONS: Liposomes are specifically internalized by retinal Müller glial cells and resident macrophages in the eye. A limited passage of fluorescent liposomes from the vitreous to the spleen via the conventional outflow pathway and the venous circulation was detected. The majority of fluorescent liposomes deposited in the conjunctiva following IVT injection reached the subcapsular sinus of the cervical LN via conjuntival lymphatics. In the cervical LN, Rh-Lip were internalized by resident subcapsular sinus macrophages adjacent to T lymphocytes. Detection of VIP in both macrophages and T cells in cervical LN suggests that IVT injection of VIP-Rh-Lip may increase ocular immune privilege by modulating the loco-regional immune environment. In conclusion, our observations suggest that IVT injection of VIP-loaded liposomes is a promising therapeutic strategy to dampen ocular inflammation by modulating macrophage and T cell activation mainly in the loco-regional immune system.

A peptide inhibitor of c-Jun N-terminal kinase for the treatment of endotoxin-induced uveitis.

PURPOSE: To evaluate the effect of XG-102 (formerly D-JNKI1), a TAT-coupled dextrogyre peptide that selectively inhibits the c-Jun N-terminal kinase, in the treatment of endotoxin-induced uveitis (EIU). METHODS: EIU was induced in Lewis rats by LPS injection. XG-102 was administered at the time of LPS challenge. The ocular biodistribution of XG-102 was evaluated using immunodetection at 24 hours after either 20 microg/kg IV (IV) or 0.2 microg/injection intravitreous (IVT) administrations in healthy or uveitic eyes. The effect of XG-102 on EIU was evaluated using clinical scoring, infiltration cell quantification, inducible nitric oxide synthase (iNOS) expression and immunohistochemistry, and cytokines and chemokines kinetics at 6, 24, and 48 hours using multiplex analysis on ocular media. Control EIU eyes received vehicle injection IV or IVT. The effect of XG-102 on c-Jun phosphorylation in EIU was evaluated by Western blot in eye tissues. RESULTS: After IVT injection, XG-102 was internalized in epithelial cells from iris/ciliary body and retina and in glial and microglial cells in both healthy and uveitic eyes. After IV injection, XG-102 was concentrated primarily in inflammatory cells of uveitic eyes. Using both routes of administration, XG-102 significantly inhibited clinical signs of EIU, intraocular cell infiltration, and iNOS expression together with reduced phosphorylation of c-Jun. The anti-inflammatory effect of XG-102 was mediated by iNOS, IFN-gamma, IL-2, and IL-13. CONCLUSIONS: This is the first evidence that interfering with the JNK pathway can reduce intraocular inflammation. Local administration of XG-102, a clinically evaluated peptide, may have potential for treating uveitis.

Shorter time to diagnosis and improved stage at presentation in Swiss patients with retinoblastoma treated from 1963 to 2004

Rapport de synthèse : Le rétinoblastome est la tumeur de l'oeil la plus fréquente chez l'enfant. Un diagnostic précoce est important pour sauver le globe oculaire et la survie du patient. Le but de notre étude est de déterminer l'évolution de l'intervalle diagnostique, c'est-à-dire le délai entre les premiers symptômes et la date du diagnostic officiel du rétinoblastome, sur une période de 40 ans en Suisse. Matériel et méthode : Il s'agit d'une étude rétrospective faite sur 139 patients suisses traités pour rétinoblastome durant trois différentes périodes : (1) 1963-1983 ; (2) 1984-1993 ; et (3) 1994-2004. On compare certaines caractéristiques : le sexe du patient, la latéralité de la maladie, les premiers symptômes, leurs observateurs, l'intervalle diagnostique, l'âge au diagnostic, le stade de la maladie, l'histoire familiale. Résultats : 37 patients (26.6%) ont été traités dans la première période ; 44 (31.7%) dans la période 2 et 58 (41.7%) dans la période 3. L'intervalle diagnostique diminue de façon significative de 6.97 mois dans la période 1 à 3.58 dans la période 2 à 2.25 dans la période 3 pour le total des malades. Ceci reste significatif pour les rétinoblastomes unilatéraux. De plus, dans ce même groupe, on observe une diminution significative des stades avancés de la maladie, groupe E selon Murphree (61.5% dans la période 1 ; 46.7% dans la période 2 et 22.2 % dans la période 3). Lorsque la maladie est bilatérale, les mêmes observations se font de façon un peu moins marquée. Il n'y a aucun patient diagnostiqué au stade E de la maladie en présence d'une anamnèse familiale positive. Leucocorie (48.2%) et strabisme (20.1 %) sont les symptômes les plus fréquents durant les 3 périodes. Les seuls facteurs qui influencent significativement le risque d'avoir un stade E de la maladie sont la durée de l'intervalle diagnostic et la période de diagnostic. Conclusion : On constate un progrès dans le diagnostic du rétinoblastome en Suisse, surtout lors de maladie unilatérale. De même, des améliorations sont notées dans la maladie bilatérale mais de façon non significative. Il est donc important de mieux enseigner aux médecins à reconnaître les symptômes oculaires de la maladie et à référer les patients plus tôt aux spécialistes. Abstract : OBECTIVES : Retinoblastoma is the most frequent intraocular malignancy in children. Early diagnosis is essential for globe salvage and patient survival. The aim of our study was to determine how time to diagnosis of retinoblastoma has evolved over a 40-year period in Switzerland. METHOD AND PATIENTS : A retrospective study of 139 Swiss patients with retinoblastoma was performed comparing 3 periods: (1) 1963-1983; (2) 1984-1993; and (3) 1994-2004. Factors taken into account were gender, laterality of retínoblastoma, age at first symptoms, type and first observer of symptoms, time to diagnosis, age at diagnosis, disease stage, and family history. RESULTS : Thirty-seven patients (26.6%) were treated in period 1, 44 (31.7%) in period 2, and S8 (41.7%) in period 3.Overall, the diagnostic interval decreased in a significant way from 6.97 months in period 1 to 3.58 in period 2 and to 2.25 in period 3. When looking separately at unilateral and bilateral disease, the decrease oí the diagnostic interval remained statistically significant in unilateral retinoblastoma; there was also a significant reduction in the number of patients with advanced group E disease (Murphree classification) (61.5% in period 1, 46.7% in period 2, 22.2% in period 3). In bilateral disease, the same observations were made to a lesser extent. However, there were no cases with group E disease in 10 patients with positive family history. Leukornria (48.2%) and strabismus (20.1 %) were the 2 most frequent symptoms throughout the 3 periods. The only factors that statistically influenced the chances of having a diagnosis of group E disease were the diagnostic interval and period of diagnosis. Conclusion : Progress has been made in the diagnosis of retinoblastoma in Switzerland, notably in unilateral disease. Improvement to a lesser extent has also been observed in bilateral cases but without statistical significance. Greater effort is needed to teach physians-in-training to recognize the importance of ocular symptoms and refer patients earlier.

Subconjunctival Injection of XG-102, a c-Jun N-Terminal Kinase Inhibitor Peptide, in the Treatment of Endotoxin-Induced Uveitis in Rats.

Abstract Purpose: XG-102, a TAT-coupled dextrogyre peptide inhibiting the c-Jun N-terminal kinase, was shown efficient in the treatment of experimental uveitis. Preclinical studies are now performed to determine optimal XG-102 dose and route of administration in endotoxin-induced uveitis (EIU) in rats with the purpose of clinical study design. METHODS: EIU was induced in Lewis rats by lipopolysaccharides (LPS) injection. XG-102 was administered at the time of LPS challenge by intravenous (IV; 3.2, 35 or 355&#8201;&#956;g/injection), intravitreal (IVT; 0.08, 0.2 or 2.2&#8201;&#956;g/eye), or subconjunctival (SCJ; 0.2, 1.8 or 22&#8201;&#956;g/eye) routes. Controls received either the vehicle (saline) or dexamethasone phosphate injections. Efficacy was assessed by clinical scoring, infiltrating cells count, and expression of inflammatory mediators [inducible nitric oxide synthase (iNOS), cytokine-induced neutrophil chemoattractant-1 (CINC-1)]. The effect of XG-102 on phosphorylation of c-Jun was evaluated by Western blot. RESULTS: XG-102 demonstrated a dose-dependent anti-inflammatory effect in EIU after IV and SCJ administrations. Respective doses of 35 and 1.8&#8201;&#956;g were efficient as compared with the vehicle-injected controls, but only the highest doses, respectively 355 and 22&#8201;&#956;g, were as efficient as dexamethasone phosphate. After IVT injections, the anti-inflammatory effect of XG-102 was clinically evaluated similar to the corticoid's effect with all the tested doses. Regardless of the administration route, the lowest efficient doses of XG-102 significantly decreased the ration of phospho c-Jun/total c-Jun, reduced cells infiltration in the treated eyes, and significantly downregulated iNOS and CINC-1 expression in the retina. CONCLUSION: These results confirm that XG-102 peptide has potential for treating intraocular inflammation. SCJ injection appears as a good compromise to provide a therapeutic effect while limiting side effects.

Entre hybris et mélancolie : poétique, esthétique et usages de la liste dans le roman français contemporain (1963-2013)

Forme archaïque, présente dès l'aube de l'écriture; forme ergonomique, présente autour de nous de manière bien plus courante que toute narration; la liste est un objet fascinant, qui ne dévoile jamais autant sa complexité que lorsqu'elle apparaît dans un cadre littéraire. Un cadre permettant de questionner, en les confrontant, la liste et son énonciateur - son sujet. Qui parle quand une liste se dit? Que dit-elle de celui qui l'énonce? Qui parle, lorsque la syntaxe se bouleverse au point de détruire les hiérarchies permettant habituellement de fixer au discours une origine, une destination, une reprise en charge? Il s'agira de répondre à ces questions et donc de passer d'une poétique à une éthique de la liste, afin de montrer que la description d'un tel objet est indissociable de sa contextualisation discursive, sa subjectivisation. Celle-ci traverse, par une constante métalepse (glissement entre les instances de responsabilité du discours), tout le spectre des actants du texte-liste - de la figure d'auteur à celle du lecteur. La spécificité de la liste littéraire se déporte alors dans un espace éthique, puis bientôt thymique, constitué par un faisceau d'oppositions : par exemple, la liste peut être fermée ou ouverte, hyper- ou hypolisible ; signe d'ordre (c'est l'inventaire, où à l'item correspond la chose) comme de désordre (c'est l'accumulation proliférante). Mais le couple oppositionnel le plus fécond est constitué par l'hybris et la mélancolie: hybris, ou l'orgueil de croire à une réinvention du monde par le pouvoir d'une juxtaposition sans limites. Mélancolie, ou miroitement du mot manquant, évidence de l'absence. C'est sous l'égide de cette opposition que je traite un vaste corpus constitué de huit auteurs contemporains, marqués par un XXe siècle catastrophique, où à l'hybris pléthorique de l'expression de la monstruosité et de l'abondance (J-M.G. Le Clézio, Georges Perec, Eric Chevillard) répond la mélancolie d'une absence ontologique : identitaire (Patrick Modiano), épistémologique (Pierre Senges) langagière (Pascal Quignard, Olivia Rosenthal), voire politique (Antoine Volodine).

Réunion et désunions autour du cinéma-vérité : le MIPE-TV 1963 de Lyon

Au début des années 1960, les documentaristes Jean Rouch, Mario Ruspoli, Richard Leacock, Robert Drew et Michel Brault se réclament d'une proximité inédite avec le réel filmé et oeuvrent activement à la création de nouvelles caméras légères et synchrones: c'est le temps du « cinéma-vérité » qui déchaîne en France de vives polémiques. En mars 1963, constructeurs d'appareils, cinéastes et journalistes sont invités par Pierre Schaeffer à discuter de ces questions lors des Journées d'Etudes du MIPE-TV. Cette manifestation, moment nodal du « cinéma-vérité », est l'occasion de se réunir autour des nouvelles techniques légères, mais aussi de débattre des enjeux éthiques et moraux de ce cinéma et de prendre position sur la controverse terminologique qui oppose les partisans de l'expression consensuelle « cinéma direct » aux adeptes de la notion polémique « cinéma-vérité ».
