Viruses have evolved strategies to overcome the antiviral effects of the host at different levels. Besides specific defence mechanisms, the host responds to viral infection via the interferon pathway and also by RNA interference (RNAi). However, several viruses have been identified that suppress RNAi. We addressed the question of whether hepatitis C virus (HCV) suppresses RNAi, using cell lines constitutively expressing green fluorescent protein (GFP) and inducibly expressing HCV proteins. It was found that short interfering RNA-mediated GFP gene silencing was inhibited when the entire HCV polyprotein was expressed. Further studies showed that HCV structural proteins, and in particular envelope protein 2 (E2), were responsible for this inhibition. Co-precipitation assays demonstrated that E2 bound to Argonaute-2 (Ago-2), a member of the RNA-induced silencing complex, RISC. Thus, HCV E2 that interacts with Ago-2 is able to suppress RNAi.

"Argent et stupéfiants, stupéfiants et argent" : c'est un binôme bien implanté dans l'imaginaire commun. La production, le transport et la vente de stupéfiants constituent l'un des principaux trafics illicites au niveau international et permettent, à travers le blanchiment de l'argent qui en est issu, de financer beaucoup d'activités illégales. Dans ce cadre, le monde judiciaire montre un intérêt tout particulier à pouvoir démontrer que des sommes d'argent ont été en contact avec des produits stupéfiants et donc de les relier à leur trafic. C'est dans cette optique que l'analyse des contaminations en produits stupéfiants que l'on retrouve sur les billets de banque constitue un outil intéressant. Il s'agit de pouvoir établir que des billets en circulation présentent peu de traces de stupéfiants alors que les billets saisis dans le cadre de la répression du trafic illicite de stupéfiants en présentent en quantité plus importante. Les résultats de cette étude confirment qu'il est possible de mettre en évidence une différence significative entre la population des billets en circulation et la population des billets saisis tant pour les francs suisses que pour les euros. La méthodologie développée pour déterminer si un lot de billets est relié au trafic de produits stupéfiants est ainsi validée et constitue une contribution nouvelle dans la lutte contre le trafic des stupéfiants.

Thème classique des études sur l'enseignement supérieur, les inégalités redeviennent un sujet polémique : la crise économique et financière des années 2008-2012 interroge notamment la capacité des individus ou des familles à financer des études supérieures. Elle questionne également les universités dans leurs missions, leurs structures, leur attractivité et leurs financements. Dans le contexte de massification des études tertiaires, le triple mouvement de différenciation, de compétition et d'internationalisation des enseignements supérieurs a eu pour effet, au cours des dernières années, le renouvellement et la diversification des problématiques de recherche dans le domaine des inégalités sociales. De la fatalité à l'action, les inégalités constituent dorénavant l'une des problématiques dominantes des réflexions menées sur l'enseignement supérieur et les universités. Pour essayer de comprendre les processus à l'oeuvre, cet ouvrage vise à répondre à quatre grandes questions : quelles sont les inégalités actuellement observables dans l'enseignement supérieur ? Comment sont-elles (re)produites ? Quelles en sont les conséquences en termes d'accès, de succès, de carrière et de genre ? Comment sont-elles traitées politiquement, socialement et institutionnellement ?

The motivation for this research initiated from the abrupt rise and fall of minicomputers which were initially used both for industrial automation and business applications due to their significantly lower cost than their predecessors, the mainframes. Later industrial automation developed its own vertically integrated hardware and software to address the application needs of uninterrupted operations, real-time control and resilience to harsh environmental conditions. This has led to the creation of an independent industry, namely industrial automation used in PLC, DCS, SCADA and robot control systems. This industry employs today over 200'000 people in a profitable slow clockspeed context in contrast to the two mainstream computing industries of information technology (IT) focused on business applications and telecommunications focused on communications networks and hand-held devices. Already in 1990s it was foreseen that IT and communication would merge into one Information and communication industry (ICT). The fundamental question of the thesis is: Could industrial automation leverage a common technology platform with the newly formed ICT industry? Computer systems dominated by complex instruction set computers (CISC) were challenged during 1990s with higher performance reduced instruction set computers (RISC). RISC started to evolve parallel to the constant advancement of Moore's law. These developments created the high performance and low energy consumption System-on-Chip architecture (SoC). Unlike to the CISC processors RISC processor architecture is a separate industry from the RISC chip manufacturing industry. It also has several hardware independent software platforms consisting of integrated operating system, development environment, user interface and application market which enables customers to have more choices due to hardware independent real time capable software applications. An architecture disruption merged and the smartphone and tablet market were formed with new rules and new key players in the ICT industry. Today there are more RISC computer systems running Linux (or other Unix variants) than any other computer system. The astonishing rise of SoC based technologies and related software platforms in smartphones created in unit terms the largest installed base ever seen in the history of computers and is now being further extended by tablets. An underlying additional element of this transition is the increasing role of open source technologies both in software and hardware. This has driven the microprocessor based personal computer industry with few dominating closed operating system platforms into a steep decline. A significant factor in this process has been the separation of processor architecture and processor chip production and operating systems and application development platforms merger into integrated software platforms with proprietary application markets. Furthermore the pay-by-click marketing has changed the way applications development is compensated: Three essays on major trends in a slow clockspeed industry: The case of industrial automation 2014 freeware, ad based or licensed - all at a lower price and used by a wider customer base than ever before. Moreover, the concept of software maintenance contract is very remote in the app world. However, as a slow clockspeed industry, industrial automation has remained intact during the disruptions based on SoC and related software platforms in the ICT industries. Industrial automation incumbents continue to supply systems based on vertically integrated systems consisting of proprietary software and proprietary mainly microprocessor based hardware. They enjoy admirable profitability levels on a very narrow customer base due to strong technology-enabled customer lock-in and customers' high risk leverage as their production is dependent on fault-free operation of the industrial automation systems. When will this balance of power be disrupted? The thesis suggests how industrial automation could join the mainstream ICT industry and create an information, communication and automation (ICAT) industry. Lately the Internet of Things (loT) and weightless networks, a new standard leveraging frequency channels earlier occupied by TV broadcasting, have gradually started to change the rigid world of Machine to Machine (M2M) interaction. It is foreseeable that enough momentum will be created that the industrial automation market will in due course face an architecture disruption empowered by these new trends. This thesis examines the current state of industrial automation subject to the competition between the incumbents firstly through a research on cost competitiveness efforts in captive outsourcing of engineering, research and development and secondly researching process re- engineering in the case of complex system global software support. Thirdly we investigate the industry actors', namely customers, incumbents and newcomers, views on the future direction of industrial automation and conclude with our assessments of the possible routes industrial automation could advance taking into account the looming rise of the Internet of Things (loT) and weightless networks. Industrial automation is an industry dominated by a handful of global players each of them focusing on maintaining their own proprietary solutions. The rise of de facto standards like IBM PC, Unix and Linux and SoC leveraged by IBM, Compaq, Dell, HP, ARM, Apple, Google, Samsung and others have created new markets of personal computers, smartphone and tablets and will eventually also impact industrial automation through game changing commoditization and related control point and business model changes. This trend will inevitably continue, but the transition to a commoditized industrial automation will not happen in the near future.

Introduction: En Suisse, toute hospitalisation pour un séjour de¦réadaptation doit être soumise à l'accord préalable du service du¦médecin-conseil de l'assurance du patient. Les assureurs fixent ensuite¦le nombre de jours d'hospitalisation qu'ils s'engagent à financer¦(délai de garantie initial). Dans le canton de Vaud, ces délais sont¦hétérogènes entre assureurs et souvent trop courts, ce qui nécessite¦fréquemment une demande de prolongation de garantie (jusqu'à 80%¦des hospitalisations dans certains services de réadaptation). Un travail¦précédent a montré la validité d'un groupage, basé principalement sur¦l'état fonctionnel du patient à l'admission (score d'activités de la vie¦quotidienne de base [AVQ]), pour prédire les durées de séjour en¦réadaptation. L'objectif de cette étude est d'évaluer si les scores AVQ¦communiqués aux assureurs permettraient d'établir un délai de garantie¦correspondant au plus près à la durée de séjour effective des patients¦en réadaptation, afin de diminuer le nombre de demandes de¦prolongation sans induire une augmentation artificielle des durées de¦séjour.¦Méthode: Les données de 2335 patients admis consécutivement sur¦une durée de trois ans au Centre de Traitement et de Réadaptation¦gériatrique du Centre Hospitalier Universitaire Vaudois (CUTR) ont été¦analysées rétrospectivement. Des délais de garantie fictifs ont été¦calculés à partir de plusieurs algorithmes utilisant des groupages de¦patients basés uniquement sur leurs AVQ à l'admission, et comparés¦aux durées de séjour effectives ainsi qu'aux délais de garantie initiaux¦fournis par les assureurs.¦Résultats: Une règle d'allocation de délais de garantie initiaux proches¦des durées réelles de séjour a pu être produite. Son application au¦CUTR réduirait la proportion estimée de séjours pour lesquels une¦demande de prolongation est nécessaire de 69% à 46% (0,1 EPT¦économisé). La proportion globale de jours en excès accordés par¦l'assureur passerait de 7% à 11%.¦Conclusion: L'utilisation systématique d'une règle d'allocation utilisant¦l'état fonctionnel du patient pour définir le délai de garantie initial¦accordé par les assureurs permettrait de diminuer de façon importante¦le nombre de demandes de prolongation. Cette mesure contribuerait à¦alléger les charges administratives, aussi bien pour les assureurs que¦pour les services de réadaptation. La proportion de jours accordés en¦excès resterait faible, limitant le risque d'augmentation artificielle de la¦durée de séjour.

La surveillance financière contemporaine est toute entière associée à la volonté de tirer avantage des technologies de l'information et de la communication dans le but d'identifier et de suivre les flux de capitaux au nom de la lutte contre le blanchiment d'argent et le financement du terrorisme. Légitimées pour éviter tout blocage abrupt des mobilités, les techniques destinées à financer ces flux tendent à cadrer la circulation financière. Leur mise en place crée des obligations pour de nombreux acteurs économiques érigés en filtres protecteurs de l'architecture financière internationale. L'importance de cette logique de traçabilité a été amplifiée au lendemain des attentats du 11 septembre 2001, avec une stigmatisation accrue de tout ce qui n'est pas "traçable". L'objectif de cet article est précisément d'éclairer cette articulation entre promotion de la traçabilité et effets de stigmatisation dans un contexte bien précis de "panique morale" et de mise en priorité des problématiques antiterroristes. Le traitement réservé aux systèmes informels de transfert d'argent, souvent regroupés de manière abusive sous le terme <i>hawala</i>, en est l'exemple frappant.

BACKGROUND: Gemcitabine plus cisplatin (GC) has been adopted as a neoadjuvant regimen for muscle-invasive bladder cancer despite the lack of Level I evidence in this setting. METHODS: Data were collected using an electronic data-capture platform from 28 international centers. Eligible patients had clinical T-classification 2 (cT2) through cT4aN0M0 urothelial cancer of the bladder and received neoadjuvant GC or methotrexate, vinblastine, doxorubicin, plus cisplatin (MVAC) before undergoing cystectomy. Logistic regression was used to compute propensity scores as the predicted probabilities of patients being assigned to MVAC versus GC given their baseline characteristics. These propensity scores were then included in a new logistic regression model to estimate an adjusted odds ratio comparing the odds of attaining a pathologic complete response (pCR) between patients who received MVAC and those who received GC. RESULTS: In total, 212 patients (146 patients in the GC cohort and 66 patients in the MVAC cohort) met criteria for inclusion in the analysis. The majority of patients in the MVAC cohort (77%) received dose-dense MVAC. The median age of patients was 63 years, they were predominantly men (74%), and they received a median of 3 cycles of neoadjuvant chemotherapy. The pCR rate was 29% in the MVAC cohort and 31% in the GC cohort. There was no significant difference in the pCR rate when adjusted for propensity scores between the 2 regimens (odds ratio, 0.91; 95% confidence interval, 0.48-1.72; P = .77). In an exploratory analysis evaluating survival, the hazard ratio comparing hazard rates for MVAC versus GC adjusted for propensity scores was not statistically significant (hazard ratio, 0.78; 95% confidence interval, 0.40-1.54; P = .48). CONCLUSIONS: Patients who received neoadjuvant GC and MVAC achieved comparable pCR rates in the current analysis, providing evidence to support what has become routine practice.

One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age-standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. We used data from 751 studies including 4,372,000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-7.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target. Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. Wellcome Trust.

BACKGROUND: Underweight and severe and morbid obesity are associated with highly elevated risks of adverse health outcomes. We estimated trends in mean body-mass index (BMI), which characterises its population distribution, and in the prevalences of a complete set of BMI categories for adults in all countries. METHODS: We analysed, with use of a consistent protocol, population-based studies that had measured height and weight in adults aged 18 years and older. We applied a Bayesian hierarchical model to these data to estimate trends from 1975 to 2014 in mean BMI and in the prevalences of BMI categories (<18·5 kg/m(2) [underweight], 18·5 kg/m(2) to <20 kg/m(2), 20 kg/m(2) to <25 kg/m(2), 25 kg/m(2) to <30 kg/m(2), 30 kg/m(2) to <35 kg/m(2), 35 kg/m(2) to <40 kg/m(2), ≥40 kg/m(2) [morbid obesity]), by sex in 200 countries and territories, organised in 21 regions. We calculated the posterior probability of meeting the target of halting by 2025 the rise in obesity at its 2010 levels, if post-2000 trends continue. FINDINGS: We used 1698 population-based data sources, with more than 19·2 million adult participants (9·9 million men and 9·3 million women) in 186 of 200 countries for which estimates were made. Global age-standardised mean BMI increased from 21·7 kg/m(2) (95% credible interval 21·3-22·1) in 1975 to 24·2 kg/m(2) (24·0-24·4) in 2014 in men, and from 22·1 kg/m(2) (21·7-22·5) in 1975 to 24·4 kg/m(2) (24·2-24·6) in 2014 in women. Regional mean BMIs in 2014 for men ranged from 21·4 kg/m(2) in central Africa and south Asia to 29·2 kg/m(2) (28·6-29·8) in Polynesia and Micronesia; for women the range was from 21·8 kg/m(2) (21·4-22·3) in south Asia to 32·2 kg/m(2) (31·5-32·8) in Polynesia and Micronesia. Over these four decades, age-standardised global prevalence of underweight decreased from 13·8% (10·5-17·4) to 8·8% (7·4-10·3) in men and from 14·6% (11·6-17·9) to 9·7% (8·3-11·1) in women. South Asia had the highest prevalence of underweight in 2014, 23·4% (17·8-29·2) in men and 24·0% (18·9-29·3) in women. Age-standardised prevalence of obesity increased from 3·2% (2·4-4·1) in 1975 to 10·8% (9·7-12·0) in 2014 in men, and from 6·4% (5·1-7·8) to 14·9% (13·6-16·1) in women. 2·3% (2·0-2·7) of the world's men and 5·0% (4·4-5·6) of women were severely obese (ie, have BMI ≥35 kg/m(2)). Globally, prevalence of morbid obesity was 0·64% (0·46-0·86) in men and 1·6% (1·3-1·9) in women. INTERPRETATION: If post-2000 trends continue, the probability of meeting the global obesity target is virtually zero. Rather, if these trends continue, by 2025, global obesity prevalence will reach 18% in men and surpass 21% in women; severe obesity will surpass 6% in men and 9% in women. Nonetheless, underweight remains prevalent in the world's poorest regions, especially in south Asia. FUNDING: Wellcome Trust, Grand Challenges Canada.

Les communes suisses sont largement souveraines pour financer leurs activités. Leurs ressources proviennent avant tout de l'impôt sur le revenu et de l'impôt foncier prélevés auprès des ménages et des entreprises. Une crise, comme celle de 2008, qui touche la sphère financière et l'économie en général risque d'avoir des répercussions directes sur les budgets locaux. Dans le présent article, nous examinons la manière dont les communes perçoivent ce risque et y réagissent. Dans une enquête menée à l'échelle nationale fin 2009 dans les 2596 communes suisses, nous avons demandé aux secrétaires municipaux quelles mesures avaient été prises face aux pertes fiscales attendues et à la hausse possible des dépenses sociales suite à la crise de 2008. Des mesures keynésiennes ont-elles été prises, en augmentant les dépenses et en acceptant des déficits plus importants, ou y a-t-il eu tentative de limiter les déficits par des mesures d'austérité, notamment en restreignant les investissements prévus ? Nos résultats indiquent que quelques communes seulement (essentiellement les plus grandes) s'attendaient à être durement touchées par la crise. On n'observe cependant pas de tendance systématique et conforme à la théorie. Certes des mesures d'austérité ont été mises en place ou un déficit budgétaire a été provoqué, mais bon nombre de communes ont appliqué simultanément des mesures relevant des deux théories. L'impact perçu de la crise au niveau local et l'appartenance de la commune à la partie francophone du pays sont les principaux facteurs expliquant la réaction des communes et les raisons de cette réaction. La taille de la commune joue aussi un rôle. Mais l'influence du parti social-démocrate est négligeable. Le type de mesures que les communes sont susceptibles de prendre est plus difficile à expliquer. Cependant, plus une commune se sent touchée, plus elle s'orientera vers des mesures d'austérité.
