Recontextualisation
Authors: Treleani Matteo 
Published: May 2013

La recontextualisation est un phénomène typique des média numériques. Sans doute plus fréquente que la reproduction, la recontextualisation concerne la reprise d’un objet culturel dans un nouveau contexte médiatique. Pour mieux comprendre le phénomène, nous analyserons un exemple à partir d’archives télévisuelles et plus spécifiquement une éditorialisation des images du 11 septembre 2001 par la fondation Internet Archive. Cet exemple nous permettra de dégager deux formes de recontextualisation, la recontextualisation temporelle et la recontextualisation du support. Il s’agira de travailler sur deux fronts : l’historiographie (comment comprendre au présent un document du passé) et l’étude de la publication en ligne d’un document (comment un document est mis en forme par un medium numérique). Au carrefour de ces deux fronts une approche sémiotique transversale sera pertinente pour aboutir à une analyse globale.
Le droit d'être homosexuel et la question du mariage
Authors: Faes Hubert 
Published: May 2013

Parmi les droits de l’homme figure logiquement le droit d’être homosexuel, même si l’on a peu l’habitude de le formuler ainsi. Il s’agit d’abord d’exister dans sa condition, ce qui suppose de bien comprendre ce que l’on entend par condition humaine. De nos jours, cette approche n’a plus grand-chose à voir avec la théologie médiévale ; user de l’argument anthropologique dans le cadre de cette réflexion ne va pas de soi. Les personnes homosexuelles vivent autrement la différence des sexes irréductibles à la biologie, y compris lorsqu’on s’interroge sur la paternité et la maternité. Pouvons-nous encore, en matière de morale chrétienne, nous appuyer sur la seule idée d’une nature humaine universelle ? Enfin, qui peut soutenir que l’homosexualité serait un empêchement à l’amour du prochain ? La crainte de l’inconnu est encore ce qui explique le mieux l’opposition des Églises à l’homoparentalité.
La boue de Saint-Denis (1824) : Astolphe de Custine, « un homme marqué du sceau de la réprobation »
Authors: Diethelm Marie-Bénédicte 
Published: May 2013

Astolphe, marquis de Custine (1790-1857), auteur de La Russie en 1839 (1843) et figure marquante de la littérature du XIX e siècle, fut victime d’une agression d’une violence inouïe pour avoir donné rendez-vous à un jeune soldat en octobre 1824. L’homosexualité du marquis, une fois connue de tous, entraîna son exclusion de la « bonne société », scindant sa vie entre un avant et un après. On se propose ici d’établir aussi exactement que possible les faits de l’« affaire Custine » dans l’espoir de parvenir à mettre en lumière les raisons d’un ostracisme retentissant qui ne semble pas avoir eu d’équivalent au cours du premier XIX e siècle.
Presse, mondanité et saphisme décoratif
Authors: Sadoun-Édouard Clara 
Published: May 2013

L’article analyse le rapport à l’homosexualité féminine dans la Vie parisienne , revue illustrée qui constitue un observatoire stimulant pour analyser les représentations de l’homosexualité à la fin du XIX e siècle. En effet, la Vie parisienne est une revue mondaine et galante : à ce titre, elle reproduit le discours social dominant. Cependant, la revue fait aussi de la figure de l’homosexuelle le socle de son pacte de lecture et établit une analogie entre presse galante et une vision « décorative » de l’homosexualité féminine. Elle se présente en effet comme une jolie femme, prétend s’adresser exclusivement aux femmes et se spécialise dans les confidences de femmes entre elles, dans une obsession, une érotisation, une « glorification de la femme » (Jules Lemaître) permanente. Ce faisant, elle invente une nouvelle forme de presse qui repose sur une fiction participative : l’exploitation du voyeurisme libertin où la revue entraîne son lectorat dans une fête galante et élégante où revue, rédacteurs, lecteurs et lectrices se travestissent en lesbiennes façon gravure grivoise.
Le socle de protection sociale
Authors: Hirsch Martin 
Published: May 2013

En 2009, en pleine crise économique internationale, l’ensemble des organisations onusiennes mettait en place une commission chargée de rendre un rapport sur la notion de socle de protection sociale, composée de personnalités ayant toutes exercé de hautes responsabilités politiques. Ce rapport met en avant plusieurs éléments nouveaux : le niveau de richesse nationale n’est pas nécessairement corrélé à la possibilité de construction de la protection sociale ; la protection sociale est un élément créant de la richesse et contribuant au développement ; la protection sociale n’est pas un frein à la croissance. Mais pour qu’elle montre son efficacité, la protection sociale doit être conçue du côté de la demande (assurance maladie) comme du côté de l’offre (professionnels de santé), et évaluée.

Abstract
Unraveling the mechanisms involved in chemotactic navigation of immune cells is of particular interest for the development of new immunoregulatory therapies. It is generally agreed upon that members of the classical transient receptor potential channel family (TRPC) are involved in chemotaxis. However, the regulatory role of TRPC channels in chemoattractant receptor-mediated signaling has not yet been clarified in detail. In this study, we demonstrate that the TRPC6 channels play a pronounced role in CXCR2-mediated intermediary chemotaxis, whereas N-formyl-methionine-leucine-phenylalanine receptor–mediated end-target chemotaxis is TRPC6 independent. The knockout of TRPC6 channels in murine neutrophils led to a strongly impaired intermediary chemotaxis after CXCR2 activation which is not further reinforced by CXCR2, PI3K, or p38 MAPK inhibition. Furthermore, CXCR2-mediated Ca2+ influx but not Ca2+ store release was attenuated in TRPC6−/− neutrophils. We demonstrate that the TRPC6 deficiency affected phosphorylation of AKT and MAPK downstream of CXCR2 receptor activation and led to altered remodeling of actin. The relevance of this TRPC6-depending defect in neutrophil chemotaxis is underscored by our in vivo findings. A nonseptic peritoneal inflammation revealed an attenuated recruitment of neutrophils in the peritoneal cavity of TRPC6−/− mice. In summary, this paper defines a specific role of TRPC6 channels in CXCR2-induced intermediary chemotaxis. In particular, TRPC6-mediated supply of calcium appears to be critical for activation of downstream signaling components.
Refractory Amiodarone-induced Thyrotoxicosis: The Surgical Option

Published: May 2013

ABSTRACTAmiodarone-induced thyrotoxicosis is often poorly tolerated owing to underlying cardiac disease, and frequently resistant to medical therapy. We describe a 48-year-old patient with severe cardiac disease who developed amiodarone-associated thyrotoxicosis, refractory to standard medical therapy. Due to the unremitting thyrotoxicosis, a total thyroidectomy was performed without complications resulting in rapid correction of the thyrotoxicosis and enabling resumption of amiodarone therapy. Despite the concerns inherent to severe cardiac disease, total thyroidectomy can be performed safely in patients with resistant amiodarone-induced thyrotoxicosis. We believe that surgery should be considered early in the treatment planning.How to cite this articleIshay A, Carmeli J, Rozner E, Luboshitzky R.

ABSTRACTEchinococcosis is a ubiquitous zoonosis. The causal organism is a flat tapeworm whose larval form causes infestations in human beings, who are its accidental hosts. It is known to occur in all parts of the body with the highest incidence in the liver, followed by the lung. Hydatid cysts in the neck are rare by themselves. We report a case of hydatidosis of the lung and central compartment of the neck, in a man who presented with pulmonary symptoms only. Computerized tomogram of the chest had revealed a hydatid cyst in the left lung and another incidental hydatid cyst in the neck. He underwent successful excision of both the cysts in one sitting.How to cite this articlePandya NR, Paul MJ, Choudhry L, Gnanamuthu BR, Krishnan K, Franklyn J, Kalita JP.

Purpose Endometriosis is an invasive gynecologic disease characterized by diminished apoptosis, sustained ectopic survival of dysfunctional endometrial cells and implantation of endometriotic lesions outside of the uterus. The purpose of this investigation was to determine the expression pattern of apoptotic and steroidogenic genes in the progenitor stem cell population of eutopic tissues from women with endometriosis and compare them to controls. The expression of these genes was determined in a subpopulation of endometrial cells that displayed CD90 positivity (CD+ve90) and colony forming capacity. Methods We obtained endometrial samples from women with or without endometriosis. Endometrial stromal cells (ESCs) were isolated and cultured for 15 days. Purified ESCs were sorted by using a multipotent mesenchymal stromal cell multi-color flow cytometry kit. Single cell cloning was performed by serial dilution in 96-micro well plates. Fifteen days later, colonies were identified (CFUs). The colonies were chosen and cultured. mRNA expression of apoptotic genes, mitogen activated kinase 14 (MAPK14), nuclear factor kappa B (NFkB), steroidogenic acute regulatory protein (StAR), aromatase (CYP19A1) and cyclo-oxygenase-2 (COX-2) were determined by qRT-PCR. Protein levels of StAR, CYP19A1 and COX-2 were determined by western blotting. Results A subset of stromal cells derived from women with endometriosis were isolated and identified as progenitor stem cells based on their CD90 positivity and colony forming ability. The cells displayed increased levels of MAPK14, NFkB, COX-2, StAR and CYP19A1 both at the mRNA and protein level compared to stromal cells derived from controls. Similarly, pro-apoptotic molecules such as Bax were decreased whereas anti-apoptotic molecules such as Bcl2 were decreased at the mRNA level compared to stromal cells derived from controls. Conclusions CD90+ve ESCs derived from women with endometriosis displayed markers suggesting stem cell-like properties and aberrant expression of apoptotic and steroidogenic enzymes which may contribute to sustained survival of these cells.

Published: May 2013

Polypoid endometriosis is a very rare form of endometriosis, mostly affecting perimenopausal women and causing different symptoms than the usual type. It forms polypoid masses that can be misdiagnosed as malignant tumors during patient management. Polypoid endometriosis arising from a cyst wall is even more rare. Here, we present a case of a 47-year-old perimenopausal patient with a large cystic tumor in the left adnexal region and an inhomogenous tissue in the uterine cavity. Hysterectomy and bilateral adnexectomy was performed. The histology showed a polypoid endometriosis growing in an endometriotic cyst and, simultaneously, a large endometrial polyp with similar structure in the uterine cavity. Our case is unique because of the extreme rarity of polypous endometriosis in an endometriotic cyst and its even more rare association with an intrauterine endometrial polyp.

Background: Ensuring appropriate cancer screenings among low-income persons with chronic conditions and persons residing in long-term care (LTC) facilities presents special challenges. This study examines the impact of having chronic diseases and of LTC residency status on cancer screening among adults enrolled in Medicaid, a joint state-federal government program providing health insurance for certain low-income individuals in the U.S. Methods: We used 2000-2003 Medicaid data for Medicaid-only beneficiaries and merged 2003 Medicare-Medicaid data for dually-eligible beneficiaries from four states to estimate the likelihood of cancer screening tests during a 12-month period. Multivariate regression models assessed the association of chronic conditions and LTC residency status with each type of cancer screening. Results: LTC residency was associated with significant reductions in screening tests for both Medicaid-only and Medicare-Medicaid enrollees; particularly large reductions were observed for receipt of mammograms. Enrollees with multiple chronic comorbidities were more likely to receive colorectal and prostate cancer screenings and less likely to receive Papanicolaou (Pap) tests than were those without chronic conditions. Conclusions: LTC residents have substantial risks of not receiving cancer screening tests. Not performing appropriate screenings may increase the risk of delayed/missed diagnoses and could increase disparities; however, it is also important to consider recommendations to appropriately discontinue screening and decrease the risk of overdiagnosis. Although anecdotal reports suggest that patients with serious comorbidities may not receive regular cancer screening, we found that having chronic conditions increases the likelihood of certain screening tests. More work is needed to better understand these issues and to facilitate referrals for appropriate cancer screenings.
Relaxing the Conductivity/Transparency Trade‐Off in MOCVD ZnO Thin Films by Hydrogen Plasma

Published: May 2013

AbstractIncreasing the conductivity of polycrystalline zinc oxide films without impacting the transparency is a key aspect in the race to find affordable and high quality material as replacement of indium‐containing oxides. Usually, ZnO film conductivity is provided by a high doping and electron concentration, detrimental to transparency, because of free carrier absorption. Here we show that hydrogen post‐deposition plasma treatment applied to ZnO films prepared by metalorganic low‐pressure chemical vapor deposition allows a relaxation of the constraints of the conductivity/transparency trade‐off. Upon treatment, an increase in electron concentration and Hall mobility is observed. The mobility reaches high values of 58 and 46 cm2V−1s−1 for 2‐μm‐ and 350‐nm‐thick films, respectively, without altering the visible range transparency. From a combination of opto‐electronic measurements, hydrogen is found, in particular, to reduce electron trap density at grain boundaries. After treatment, the values for intragrain or optical mobility are found similar to Hall mobility, and therefore, electron conduction is found to be no longer limited by the phenomenon of grain boundary scattering. This allows to achieve mobilities close to 60 cm2V−1s−1, even in ultra‐transparent films with carrier concentration as low as 1019 cm−3.

AbstractA new class of charge neutral, strongly luminescent cyclometalated platinum(II) complexes supported by dianionic tetradentate ligand are synthesized. One of these platinum(II) complexes, Y‐Pt, displays a high photoluminescence quantum yield of 86% and electroluminescence efficacy (ηpower) of up to 52 lm W−1, and is utilized as a yellow phosphorescent dopant in the fabrication of white organic light‐emitting devices (WOLEDs). WOLEDs based on conventional structures with yellow emission from Y‐Pt in combination with blue emission from bis(4,6‐difluorophenyl‐pyridinato‐N,C2′) (picolinate) iridium(III) (FIrpic) show a total ηpower of up to 31 lm W−1. A two‐fold increase in ηpower by utilizing a modified WOLED structure comprising of a composite blue host is realized. With this modified device structure, the total ηpower and driving voltage at a luminance of 1000 cd m−2 can be improved to 61 lm W−1 and 7.5 V (i.e., 10 V for control devices). The performance improvement is attributed to an effectively broaden exciton formation‐recombination zone and alleviation of localized exciton accumulation within the FIrpic‐doped composite host for reduced triplet‐triplet annihilation, yielding blue light‐emission with enhanced intensity. The modified device structure can also adopt a higher concentration of Y‐Pt towards its optimal value, leading to WOLEDs with high efficiency.
Paternal inheritance of classic X‐linked bilateral periventricular nodular heterotopia

Published: May 2013

AbstractPeriventricular nodular heterotopia (PNH) is a developmental disorder of the central nervous system, characterized by heterotopic nodules of gray matter resulting from disturbed neuronal migration. The most common form of bilateral PNH is X‐linked dominant inherited, caused by mutations in the Filamin A gene (FLNA) and associated with a wide variety of other clinical findings including congenital heart disease. The typical patient with FLNA‐associated PNH is female and presents with difficult to treat seizures. In contrast, hemizygous FLNA loss of function mutations in males are reported to be perinatally lethal. In X‐linked dominant traits like FLNA‐associated PNH the causal mutation is commonly inherited from the mother. Here, we present an exceptional family with paternal transmission of classic bilateral FLNA‐associated PNH from a mildly affected father with somatic and germline mosaicism for a c.5686G>A FLNA splice mutation to both daughters with strikingly variable clinical manifestation and PNH extent in cerebral MR imaging. Our observations emphasize the importance to consider in genetic counseling and risk assessment the rare genetic constellation of paternal transmission for families with X‐linked dominant inherited FLNA‐associated PNH. © 2013 Wiley Periodicals, Inc.
Consistency of dominance rank order: A comparison of David's scores with I&SI and Bayesian methods in macaques

AbstractIn nonhuman primate social groups, dominance ranks are usually assigned to individuals based on outcomes of dyadic agonistic encounters. Multiple approaches have been used, but currently there is no consensus. One approach, David's Scores (DS), offers dual advantages of yielding cardinal scores that may in turn be used to compute hierarchical steepness. Here we correlate rank orders yielded by DS with those yielded by both the traditionally used I&SI approach and the recently proposed parametric Bayesian approach. We use six datasets for female macaques (three despotic and three tolerant groups), and 90 artificially generated datasets modeling macaque groups. We also use the artificial datasets to determine the impact of three characteristics (group size, interaction frequency, and directional asymmetry of aggression) on the magnitude of correlation coefficients, and assess the relative utility of two indices used to compute DS: Dij versus Pij. DS‐based rank orders were strongly positively correlated with those yielded by the other two approaches for five out of the six macaque datasets, and for the majority of artificial datasets. Magnitudes of correlation coefficients were unrelated to group size or interaction frequency, but increased with directional asymmetry, suggesting methodological inconsistencies were more likely when dyads had more frequent reversals in directions of aggression. Finally, rank orders calculated using the Dij and Pij indices were similarly consistent with orders from other methods. We conclude that DS offers consistent estimates of rank orders, except perhaps in groups with very low levels of aggression asymmetry. In such “tolerant” groups, we suggest that the relatively greater methodological variability in rank orders may reflect behavioral characteristics of tolerant groups rather than computational inconsistencies between methods. We hypothesize that this quality may be quantified using posterior probability scores of Bayesian rank orders and may also index macaque social styles. Am. J.

A comparison of antemortem tooth loss in human hunter‐gatherers and non‐human catarrhines: Implications for the identification of behavioral evolution in the human fossil record
Authors: Gilmore Cassandra C. 
Published: May 2013

ABSTRACTMiddle and Late Pleistocene fossil hominin specimens with severe antemortem tooth loss are often regarded as evidence for the precocious evolution of human‐like behaviors, such as conspecific care or cooking, in ancient hominin species. The goal of this project was to ask whether the theoretical association between antemortem tooth loss and uniquely human behaviors is supported empirically in a large skeletal sample of human hunter‐gatherers, chimpanzees, orangutans, and baboons. Binomial regression modeling in a Bayesian framework allows for the investigation of the effects of tooth class, genus, age, and sex on the likelihood of tooth loss. The results strongly suggest that modern humans experience more antemortem tooth loss than non‐human primates and identify age in years as an important predictor. Once age is accounted for, the difference between the humans and the closest non‐human genus (chimpanzees) is less pronounced; humans are still more likely on average to experience antemortem tooth loss though 95% uncertainty envelopes around the average prediction for each genus show some overlap. These analyses support theoretical links between antemortem tooth loss and modern human characteristics; humans' significantly longer life history and a positive correlation between age and antemortem tooth loss explain, in part, the reason why humans are more likely to experience tooth loss than non‐human primates, but the results do not exclude behavioral differences as a contributing factor.
