Le «corps» du texte néotestamentaire dans les films Ben-Hur (1925) et Golgotha (1935)

L'article se propose de discuter la question des modalités de la référence aux évangiles au cinéma en s'attachant à l'étude de la composante verbale et de ses liens avec la représentation de la figure christique dans deux films: le premier, Ben-Hur (Fred Niblo, 1925), est une superproduction produite par Hollywood à l'époque de l'apogée du muet; le second, Golgotha (1935), est réalisé par le cinéaste français Julien Duvivier durant les premières années de la généralisation du parlant. D'un côté l'écrit (sous forme d'intertitres), de l'autre la profération orale d'un texte. Le rapprochement proposé entre ces deux films tient à la façon dont la citation néotestamentaire participe à la construction par le film de la figure de Jésus, ou plutôt à la mise à distance de celle-ci, constamment rejetée dans une forme de hors-champ.

Harmonization guidelines for HLA-peptide multimer assays derived from results of a large scale international proficiency panel of the Cancer Vaccine Consortium.

PURPOSE: The Cancer Vaccine Consortium of the Cancer Research Institute (CVC-CRI) conducted a multicenter HLA-peptide multimer proficiency panel (MPP) with a group of 27 laboratories to assess the performance of the assay. EXPERIMENTAL DESIGN: Participants used commercially available HLA-peptide multimers and a well characterized common source of peripheral blood mononuclear cells (PBMC). The frequency of CD8+ T cells specific for two HLA-A2-restricted model antigens was measured by flow cytometry. The panel design allowed for participants to use their preferred staining reagents and locally established protocols for both cell labeling, data acquisition and analysis. RESULTS: We observed significant differences in both the performance characteristics of the assay and the reported frequencies of specific T cells across laboratories. These results emphasize the need to identify the critical variables important for the observed variability to allow for harmonization of the technique across institutions. CONCLUSIONS: Three key recommendations emerged that would likely reduce assay variability and thus move toward harmonizing of this assay. (1) Use of more than two colors for the staining (2) collect at least 100,000 CD8 T cells, and (3) use of a background control sample to appropriately set the analytical gates. We also provide more insight into the limitations of the assay and identified additional protocol steps that potentially impact the quality of data generated and therefore should serve as primary targets for systematic analysis in future panels. Finally, we propose initial guidelines for harmonizing assay performance which include the introduction of standard operating protocols to allow for adequate training of technical staff and auditing of test analysis procedures.

Population Normalization with Ammonium in Wastewater-Based Epidemiology: Application to Illicit Drug Monitoring

Fluctuations in ammonium (NH4+), measured as NH4-N loads using an ion-selective electrode installed at the inlet of a sewage treatment plant, showed a distinctive pattern which was associated to weekly (i.e., commuters) and seasonal (i.e., holidays) fluctuations of the population. Moreover, population size estimates based on NH4-N loads were lower compared to census data. Diurnal profiles of benzoylecgonine (BE) and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) were shown to be strongly correlated to NH4-N. Characteristic patterns, which reflect the prolonged nocturnal activity of people during the weekend, could be observed for BE, cocaine, and a major metabolite of MDMA (i.e., 4-hydroxy-3-methoxymethamphetamine). Additional 24 h composite samples were collected between February and September 2013. Per-capita loads (i.e., grams per day per 1000 inhabitants) were computed using census data and NH4-N measurements. Normalization with NH4-N did not modify the overall pattern, suggesting that the magnitude of fluctuations in the size of the population is negligible compared to those of illicit drug loads. Results show that fluctuations in the size of the population over longer periods of time or during major events can be monitored using NH4-N loads: either using raw NH4-N loads or population size estimates based on NH4-N loads, if information about site-specific NH4-N population equivalents is available.

Transanal endoscopic microsurgery resection of rectal tumors: outcomes and recommendations.

PURPOSE: Transanal endoscopic microsurgery provides a minimally invasive alternative to radical surgery for excision of benign and malignant rectal tumors. The purpose of this study was to review our experience with transanal endoscopic microsurgery to clarify its role in the treatment of different types of rectal pathology. METHODS: A prospective database documented all patients undergoing transanal endoscopic microsurgery from October 1996 through June 2008. We analyzed patient and operative factors, complications, and tumor recurrence. For recurrence analysis, we excluded patients with fewer than 6 months of follow-up, previous excisions, known metastases at initial presentation, and those who underwent immediate radical resection following transanal endoscopic microsurgery. RESULTS: Two hundred sixty-nine patients underwent transanal endoscopic microsurgery for benign (n = 158) and malignant (n = 111) tumors. Procedure-related complications (21%) included urinary retention (10.8%), fecal incontinence (4.1%), fever (3.8%), suture line dehiscence (1.5%), and bleeding (1.5%). Local recurrence rates for 121 benign and 83 malignant tumors were 5% for adenomas, 9.8% for T1 adenocarcinoma, 23.5% for T2 adenocarcinoma, 100% for T3 adenocarcinoma, and 0% for carcinoid tumors. All 6 (100%) recurrent adenomas were retreated with endoscopic techniques, and 8 of 17 (47%) recurrent adenocarcinomas underwent salvage procedures with curative intent. CONCLUSIONS: Transanal endoscopic microsurgery is a safe and effective method for excision of benign and malignant rectal tumors. Transanal endoscopic microsurgery can be offered for (1) curative resection of benign tumors, carcinoid tumors, and select T1 adenocarcinomas, (2) histopathologic staging in indeterminate cases, and (3) palliative resection in patients medically unfit or unwilling to undergo radical resection.

Cerebrospinal fluid antimicroglial antibodies in Alzheimer disease: a putative marker of an ongoing inflammatory process.

Immunocompetent microglia play an important role in the pathogenesis of Alzheimer's disease (AD). Antimicroglial antibodies in the cerebrospinal fluid (CSF) in clinically diagnosed AD patients have been previously recorded. Here, we report the results of the analysis of the CSF from 38 autopsy cases: 7 with definite AD; 14 with mild and 10 with moderate Alzheimer's type pathology; and 7 controls. Antimicroglial antibodies were identified in 70% of patients with definite AD, in 80% of patients with moderate and in 28% of patients with mild Alzheimer's type pathology. CSF antimicroglial antibodies were not observed in any of the control cases. The results show that CSF antimicroglial antibodies are present in the majority of patients with definite AD and also in cases with moderate Alzheimer's type changes. They may also indicate dysregulation of microglial function. Together with previous observations, these findings indicate that compromised immune defense mechanisms play an important role in the pathogenesis of AD.

Genome-wide linkage in a highly consanguineous pedigree reveals two novel loci on chromosome 7 for non-syndromic familial Premature Ovarian Failure.

BACKGROUND: The human condition known as Premature Ovarian Failure (POF) is characterized by loss of ovarian function before the age of 40. A majority of POF cases are sporadic, but 10-15% are familial, suggesting a genetic origin of the disease. Although several causal mutations have been identified, the etiology of POF is still unknown for about 90% of the patients.¦METHODOLOGY/PRINCIPAL FINDINGS: We report a genome-wide linkage and homozygosity analysis in one large consanguineous Middle-Eastern POF-affected family presenting an autosomal recessive pattern of inheritance. We identified two regions with a LOD(max) of 3.26 on chromosome 7p21.1-15.3 and 7q21.3-22.2, which are supported as candidate regions by homozygosity mapping. Sequencing of the coding exons and known regulatory sequences of three candidate genes (DLX5, DLX6 and DSS1) included within the largest region did not reveal any causal mutations.¦CONCLUSIONS/SIGNIFICANCE: We detect two novel POF-associated loci on human chromosome 7, opening the way to the identification of new genes involved in the control of ovarian development and function.

Interet de la double voie d'abord dans les blepharoplasties superieures associees aux malpositions palpebrales. [Advantages of a double approach to upper blepharoplasty associated with eyelid malpositions]

During upper blepharoplasty, myocutaneous excess and fat pads are treated using an anterior approach. Eyelid malpositions such as involutional ptosis or lid retraction could be associated and should be treated with associated procedures. Aponeurotic surgery on the levator muscle can make use of the same anterior approach, with the major difficulty of dosage. In cases of ptosis with a positive epinephrine test or minor muscular retraction, the Muller muscle-conjunctival surgery via a posterior approach seems to be more reproducible. Double-approach techniques are described.

Meta-analysis identifies 13 new loci associated with waist-hip ratio and reveals sexual dimorphism in the genetic basis of fat distribution.

Waist-hip ratio (WHR) is a measure of body fat distribution and a predictor of metabolic consequences independent of overall adiposity. WHR is heritable, but few genetic variants influencing this trait have been identified. We conducted a meta-analysis of 32 genome-wide association studies for WHR adjusted for body mass index (comprising up to 77,167 participants), following up 16 loci in an additional 29 studies (comprising up to 113,636 subjects). We identified 13 new loci in or near RSPO3, VEGFA, TBX15-WARS2, NFE2L3, GRB14, DNM3-PIGC, ITPR2-SSPN, LY86, HOXC13, ADAMTS9, ZNRF3-KREMEN1, NISCH-STAB1 and CPEB4 (P = 1.9 × 10⁻⁹ to P = 1.8 × 10⁻⁴⁰) and the known signal at LYPLAL1. Seven of these loci exhibited marked sexual dimorphism, all with a stronger effect on WHR in women than men (P for sex difference = 1.9 × 10⁻³ to P = 1.2 × 10⁻&supl;³). These findings provide evidence for multiple loci that modulate body fat distribution independent of overall adiposity and reveal strong gene-by-sex interactions.

Des hommes en mouvement : vers une reconfiguration des modèles masculins? L'exemple de la Suisse

This project is a study of the men's movement in Switzerland, especially regarding organizations seeking to redefine male identity. So far, this topic has been understudied, in Switzerland. The few studies available on the subject mostly adopt a (pro)feminist perspective. Their main purpose is to criticize men's movement participants. What is more, scarce researches on this problem mostly conducted by members of the Swiss men's movement themselves are mainly descriptive and methodologically problematic. In this context, I initiated the first national and sociological study of the men's movement in Switzerland. My main goals are: firstly, to propose a typology of organizations forming the men's movement in Switzerland. Secondly, I develop a sociological analysis of this phenomenon, taking into account in this process especially the characteristics of the Swiss context. Consequently, I adopted a mixed method approach, which included two main research steps: Firstly, I defined a representative sample of men's movement organizations in Switzerland. Based on a content analysis of men's organizations' websites, I was able to distinguish three ideal-types: Radical Criticism of Masculinity, Criticism of Hegemonic Masculinity, Defense of Men and Traditional Masculinity. Based on these three concepts, I subsequently analyzed the discourse on masculinity amongst men's movement organizations. Secondly, I conducted a survey of men's movement participants. This survey was based on the results of the content analysis. In this particular stage, I mainly used factor analysis. My results show that it would be all too simplistic to characterize the men's movement, in Switzerland, as a criticism of women's emancipation. On the contrary, my analysis reveals a more complex picture: The two main factors, which influence the men's movement, in Switzerland, are the contemporary sociological context and the Swiss society's particular features. I find that male roles, on the one hand, depend very much on today's cultural shift from materialistic to self-expression values. On the other hand, male role models reflect a social adaptation process. Moreover, as a reaction to deep changes in contemporary family structures, I observe an individualization process, characterized by separation between parental and conjugal functions that greatly shapes male role models. - Cette thèse analyse le phénomène des hommes en mouvement, dans le contexte de la Suisse. Cet ensemble est formé d'organisations regroupant des hommes impliqués consciemment dans un processus d'actions et de réflexions sur l'identité masculine. La revue de la littérature révèle qu'en Suisse, le sujet des hommes en mouvement est très peu étudié. Jusqu'ici, les rares recherches s'y intéressant adoptent généralement une approche (pro)féministe, dont l'objectif est de dénoncer ce phénomène. En outre, de rares recherches, issues des acteurs mêmes de ce mouvement, proposent une vue descriptive de l'ensemble, mais souffrant de faiblesses méthodologiques. Par notre recherche, nous souhaitons contribuer à l'étude de ce sujet, en initiant la première étude d'envergure nationale portant sur les hommes en mouvement. L'objectif final est de déboucher sur une typologie des organisations réunissant les hommes en mouvement, puis sur une analyse de la spécificité de cet ensemble, dans le contexte suisse. Pour remplir ces objectifs, nous avons mis en place un dispositif de méthodes mixtes, en deux phases. Lors d'une première étape, nous avons sélectionné un échantillon représentatif de la diversité des organisations masculines. Par une analyse de contenu effectuée sur la documentation récoltée sur les sites Internet de ces dernières, nous avons pu, en utilisant une démarche inductive et qualitative, faire émerger trois idéaux-types : Critique radicale de la masculinité, Critique de la masculinité hégémonique, Défense des hommes et de la masculinité traditionnelle. Ces concepts permettent de rendre compte, de manière schématique, des trois types de discours contemporains sur l'identité masculine diffusés par les hommes en mouvement. Lors d'une seconde étape, nous avons réalisé une enquête auprès des membres des organisations masculines. Pour y parvenir, nous avons créé un questionnaire incluant des propositions élaborées à partir des résultats de l'étape précédente. Lors de cette phase, nous avons réalisé une analyse factorielle. Les résultats montrent que le phénomène du mouvement des hommes ne saurait se réduire, en Suisse, à un mouvement de ressac visant à attaquer les droits des femmes. Au contraire, il s'agit d'un phénomène complexe, fortement dépendant du contexte sociologique contemporain et des caractéristiques de la société helvétique. Nous affirmons, entre autres, que les modèles masculins observables dans cet ensemble sont façonnés, d'une part, par une transition culturelle, caractérisée par le passage des valeurs matérialistes aux valeurs d'expression de soi. D'autre part, les modèles masculins prônés par les hommes en mouvement reflètent un processus d'adaptation sociale. En effet, en réaction au contexte de reconfiguration des formes familiales, on assiste à une individualisation des rapports de filiation et au détachement de la fonction parentale et conjugale, qui imprègnent fortement les modèles masculins défendus par ces hommes.

Comparison of the efficacy and longevity of nonpenetrating glaucoma surgery with and without a new, nonabsorbable hydrophilic implant.

BACKGROUND AND OBJECTIVE: To compare the efficacy and longevity of nonpenetrating glaucoma surgery with and without the use of a nonabsorbable hydrophilic implant at the Oxford Eye Centre, Johannesburg, South Africa, and the Glaucoma Unit, Jules Gonin Ophthalmic Hospital, Lausanne, Switzerland. PATIENTS AND METHODS: In a nonrandomized, prospective study between March 1997 and December 2001, 48 eyes of 32 patients aged 18 to 86 years with primary open-angle glaucoma underwent nonpenetrating glaucoma surgery; 25 eyes with the implant and 23 eyes without it. Intraocular pressure (IOP) was recorded preoperatively and postoperatively at 1, 7, and 14 days, at 1, 3, and 6 months, and thereafter every 6 months. RESULTS: The mean preoperative IOP was 27.5 +/- 11.8 mm Hg (range, 20 to 64 mm Hg) in the implant group and 24.8 +/- 7.1 mm Hg (range, 16 to 38 mm Hg) in the control group. During the first 18 months of follow-up, both groups showed identical IOP progression and the mean IOP remained less than 14 mm Hg. After 2 years of follow-up, the IOP started to rise in the control group but remained stable in the implant group. After 30 months, the mean IOP was 12.4 +/- 2 mm Hg and the IOP decrease in percentage was 62% +/- 6% in the implant group (n = 13) versus 16.1 +/- 3 mm Hg and 34% +/- 13% in the control group (n = 15) (mean IOP, P = .0022; mean IOP decrease in percentage, P = .01). CONCLUSIONS: During the first 18 months, there was no difference in the outcomes between the two groups. After 2 years of follow-up, the mean IOP was lower and the IOP decrease in percentage was greater in the implant group compared with the control group.

Novel loci for adiponectin levels and their influence on type 2 diabetes and metabolic traits: a multi-ethnic meta-analysis of 45,891 individuals.

Circulating levels of adiponectin, a hormone produced predominantly by adipocytes, are highly heritable and are inversely associated with type 2 diabetes mellitus (T2D) and other metabolic traits. We conducted a meta-analysis of genome-wide association studies in 39,883 individuals of European ancestry to identify genes associated with metabolic disease. We identified 8 novel loci associated with adiponectin levels and confirmed 2 previously reported loci (P = 4.5×10(-8)-1.2×10(-43)). Using a novel method to combine data across ethnicities (N = 4,232 African Americans, N = 1,776 Asians, and N = 29,347 Europeans), we identified two additional novel loci. Expression analyses of 436 human adipocyte samples revealed that mRNA levels of 18 genes at candidate regions were associated with adiponectin concentrations after accounting for multiple testing (p<3×10(-4)). We next developed a multi-SNP genotypic risk score to test the association of adiponectin decreasing risk alleles on metabolic traits and diseases using consortia-level meta-analytic data. This risk score was associated with increased risk of T2D (p = 4.3×10(-3), n = 22,044), increased triglycerides (p = 2.6×10(-14), n = 93,440), increased waist-to-hip ratio (p = 1.8×10(-5), n = 77,167), increased glucose two hours post oral glucose tolerance testing (p = 4.4×10(-3), n = 15,234), increased fasting insulin (p = 0.015, n = 48,238), but with lower in HDL-cholesterol concentrations (p = 4.5×10(-13), n = 96,748) and decreased BMI (p = 1.4×10(-4), n = 121,335). These findings identify novel genetic determinants of adiponectin levels, which, taken together, influence risk of T2D and markers of insulin resistance.

L'apport d'une approche criminalistique pour lutter contre la contrefaçon de médicaments

Dans le domaine de l'analyse et la détection de produits pharmaceutiques contrefaits, différentes techniques analytiques ont été appliquées afin de discriminer les produits authentiques des contrefaçons. Parmi celles-ci, les spectroscopies proche infrarouge (NIR) et Raman ont fourni des résultats prometteurs. L'objectif de cette étude était de développer une méthodologie, basée sur l'établissement de liens chimiques entre les saisies de produits contrefaits, permettant de fournir des informations utiles pour les acteurs impliqués dans la lutte à la prolifération de ces produits. Une banque de données de spectres NIR et Raman a été créée et différents algorithmes de classification non-supervisée (i.e., analyse en composantes principales (ACP) et analyse factorielle discriminante (AFD) - elus ter onolysis) ont été utilisées afin d'identifier les différents groupes de produits présents. Ces classes ont été comparées aux profils chimiques mis en évidence par la spectroscopie infrarouge à transformée de Fourier (FT-IR) et par la chromatographie gazeuse couplée à la spectrométrie de masse (GC -MS). La stratégie de classification proposée, fondée sur les classes identifiées par spectroscopie NIR et Raman, utilise un algorithme de classification basé sur des mesures de distance et des courbes Receiver Operating Characteristics (ROC). Le modèle est capable de comparer le spectre d'une nouvelle contrefaçon à ceux des saisies précédemment analysées afin de déterminer si le nouveau spécimen appartient à l'une des classes existantes, permettant ainsi de le lier à d'autres saisies dans la base de données.

Computational quest for understanding the role of astrocyte signaling in synaptic transmission and plasticity.

The complexity of the signaling network that underlies astrocyte-synapse interactions may seem discouraging when tackled from a theoretical perspective. Computational modeling is challenged by the fact that many details remain hitherto unknown and conventional approaches to describe synaptic function are unsuitable to explain experimental observations when astrocytic signaling is taken into account. Supported by experimental evidence is the possibility that astrocytes perform genuine information processing by means of their calcium signaling and are players in the physiological setting of the basal tone of synaptic transmission. Here we consider the plausibility of this scenario from a theoretical perspective, focusing on the modulation of synaptic release probability by the astrocyte and its implications on synaptic plasticity. The analysis of the signaling pathways underlying such modulation refines our notion of tripartite synapse and has profound implications on our understanding of brain function.
