Das Projekt "Nationales Krebshilfe-Monitoring zur Solariennutzung" (National Cancer Aid Monitoring of Tanning Bed Use, NCAM) ist eine deutsche Großstudie mit dem Ziel, die wichtigsten Risikofaktoren für Hautkrebs zu beobachten: natürliches Sonnenlicht und künstliche UV-Strahlung. NCAM ist eine bundesweite Querschnittstudie mit zunächst vier Runden der Datenerfassung (sogenannten Wellen) zwischen 2015 und 2018. Jedes Jahr wird eine bundesweit repräsentative Stichprobe aus 3.000 Personen im Alter von 14 bis 45 Jahren befragt. Die Querschnittsbefragung wird durch eine Kohorte von n = 450 aktuellen Solariennutzern ergänzt. Die erste Welle im Jahr 2015 ergab eine Gesamtprävalenz der Solariennutzung von 29,5 %. Elf Prozent aller Teilnehmer hatten in den vergangenen zwölf Monaten ein Solarium genutzt. Zu den Determinanten der aktuellen Solariennutzung gehörten jüngeres Alter, weibliches Geschlecht und Vollzeit-/Teilzeitbeschäftigung. Die hauptsächlichen Beweggründe, die für die Nutzung eines Solariums genannt wurden, waren Entspannung und Attraktivitätssteigerung. NCAM ist weltweit die erste Studie zur Überwachung der Risikofaktoren für Hautkrebs in jährlichen Intervallen anhand einer großen, landesweit repräsentativen Stichprobe. Erste Ergebnisse deuten darauf hin, dass Millionen Deutsche trotz Warnungen der WHO Solarien nutzen, und dass viele dieser Nutzer Jugendliche sind - trotz gesetzlicher Beschränkungen, die das Ziel haben, die Nutzung von Solarien durch Minderjährige zu verhindern. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Bourque, Claude Julie

Le champ de la recherche scientifique et de la formation a la recherche est traverse depuis quelques dizaines d'annees par plusieurs courants et discours associes au changement, mais peu de travaux empiriques permettent de comprendre ce qui change concretement. C'est la contribution originale de cette these au champ de l'education, plus specifiquement a l'etude sociologique de l'enseignement superieur ou sont concentrees les activites liees a la triade thematique du programme doctoral dans lequel elle a ete produite : recherche, formation et pratique. L'enquete-terrain a ete realisee en 2009 et 2010 aupres de 808 repondants affilies a 60 etablissements au Quebec et a produit un vaste materiau de nature mixte (donnees quantitatives et qualitatives). Un portrait de la nebuleuse biotechnologique qui touche les secteurs des sciences de la sante, des sciences naturelles et du genie a ete realise. Ce domaine concerne des dizaines de disciplines et se revele de nature transdisciplinaire, mais les pratiques n'y sont pas davantage marquees par le changement que celles d'autres domaines connexes. Les dynamiques sociales ont fait l'objet d'analyses comparatives dans quatre contextes: le choix des programmes, des objets et des methodes, le financement, la diffusion et la planification de la carriere. Les resultats indiquent que les echanges entre les agents traditionnellement situes au coeur des activites de recherche dominent ces dynamiques dans tous les contextes etudies. L'etude des representations au fondement des pratiques a revele l'existence de trois ecoles de pensee qui coexistent dans le champ scientifique: academique, pragmatique et economiste. Ces ecoles permettent de categoriser les agents en fonction des zones de fractures qui marquent leurs oppositions tout en identifiant ce qu'ils ont en commun. Les representations et les pratiques liees a la formation temoignent d'un habitus plutot homogene, alors que les contradictions semblent plus souvent ancrees dans des

Davis, John L.

Available from UMI in association with The British Library. The thesis begins with an examination of what was understood by the term 'physics' in France circa. 1850. The development of the centralised state educational system and the physics research which was produced within this system in Paris and the provinces, is then considered. Although all the relevant institutions, where some form of physics or physical science was taught, have been examined, the Ecole Polytechnique, and the Ecole Normale Superieure have a particular importance in the early period of this study. As time passed and as a result of reforms put in hand by the republican regime which came out of the defeat of the Franco -Prussian war of 1870-71, the universite system grew in importance, while the role of the Polytechnique declined. The Ecole Normale, the Paris Faculty and the provincial faculties form part of the universite system and participated in its growth. A knowledge of the objectives of the physics courses in these institutions helps in the understanding of the characteristics of physics in France in this period. The central objective was, largely, to produce either science teachers, or (in the case of the Polytechnique), a type of elite 'technocrat', for the state, i.e. men who could communicate clearly, or technically utilise knowledge, which was already established on a firm theoretical basis. This is not to say that research had no place in the institutions of higher education, on the contrary, and this research, carried out by both teachers and students, is examined here to try to relate its form and content to the particular institution in which it was carried out. The role of national organisations like the Societe de physique and the Association Francaise pour l'avancement des sciences in the development of physics in France is also considered, as is the role of the Academie des sciences. The predominantly experimental nature of physics research in France is related to the

A career in engineering may be appealing owing to the prospect of a good salary and a dynamic work environment. There may, however, be challenges for students wishing to enter their first job. In engineering education, career preparation courses may be included so as to prepare students adequately for their first job, future careers, and to reinforce career decision-making skills. This study explored the first-job preferences and expectations of engineering students at a generalist French 'Grande Ecole' before their compulsory internship. The study ultimately provided insight into ways in which future engineers may best be equipped for their first jobs. A qualitative research study was employed, using four focus groups to collect data, which was analysed thematically. Key findings indicate the resolute importance that engineering students place on having a challenging job, teamwork, independence, opportunities for development, and a participative style of being managed. The research findings may be of value in order to renew an engineering curriculum with better alignment between students' expectations and industry needs.

Résumé Objectif Estimer les économies que pourrait engendrer la mise en œuvre d’un modèle rationnel de prescription pour des classes de médicaments équivalents sur les plans de l’efficacité, de la toxicité et de la commodité. Conception L’Institut canadien d’information sur la santé a fourni des renseignements sur les 10 principales classes de médicaments en fonction des dépenses annuelles qui leur sont attribuables. Ces classes ont été examinées en vue de leur inclusion potentielle dans l’étude selon qu’il était possible de comparer les médicaments à l’intérieur d’une même classe. Lorsqu’à la suite d’une recherche documentaire, une équivalence a été établie en fonction de l’efficacité, de la toxicité et de la commodité des médicaments, les données annuelles sur les prescriptions ont été recueillies à partir de la base de données du Système national d’information sur l’utilisation des médicaments prescrits. Les économies potentielles de coûts ont ensuite été calculées en comparant les parts de marché actuelles avec les parts potentielles futures de ce marché. Contexte Le Canada. Principaux paramètres à l’étude Les différences estimées dans les dépenses que produirait un modèle rationnel de prescription. Résultats Une équivalence a été établie sur les plans de l’efficacité, de la toxicité et de la commodité dans les classes de statines, d’inhibiteurs de la pompe à protons, d’inhibiteurs de l’enzyme de conversion de l’angiotensine et d’inhibiteurs sélectifs du recaptage de l’angiotensine. Les dépenses annuelles totales dans ces classes se situent à 856 millions $ dans les programmes publics de médicaments et à 1,97 milliard $ environ à l’échelle nationale. Grâce à des prescriptions rationnelles, on estime que les économies annuelles pourraient atteindre 222 millions $ pour les programmes publics et 521 millions $ à l’échelle nationale. Conclusion La

Probability distribution of financial returns in a model of multiplicative Brownian motion with stochastic diffusion coefficient

NASA Astrophysics Data System (ADS)

Silva, Antonio

2005-03-01

It is well-known that the mathematical theory of Brownian motion was first developed in the Ph. D. thesis of Louis Bachelier for the French stock market before Einstein [1]. In Ref. [2] we studied the so-called Heston model, where the stock-price dynamics is governed by multiplicative Brownian motion with stochastic diffusion coefficient. We solved the corresponding Fokker-Planck equation exactly and found an analytic formula for the time-dependent probability distribution of stock price changes (returns). The formula interpolates between the exponential (tent-shaped) distribution for short time lags and the Gaussian (parabolic) distribution for long time lags. The theoretical formula agrees very well with the actual stock-market data ranging from the Dow-Jones index [2] to individual companies [3], such as Microsoft, Intel, etc. [] [1] Louis Bachelier, ``Th'eorie de la sp'eculation,'' Annales Scientifiques de l''Ecole Normale Sup'erieure, III-17:21-86 (1900).[] [2] A.

Sismos a l'Ecole : a Seismic Educational Network (FRANCE) linked with Research

2007-12-01

Ahead of the quick evolution of our society, in which scientific information has to be accurately understood by a great majority, the promotion of a responsible behaviour coming from educated and trained citizens has become a priority. One of the roles of school is to enable children to understand sciences, these same sciences that were long ago the prerogative of scientific laboratories. The educational network SISMOS à l\\'"Ecole is an example of a project structured on the knowledge of seismic risks through a scientific and technological approach. It develops a teaching method leading to an approach towards the knowledge of natural disasters. The original and innovating feature of this educational network is to enable students to set up a seismograph in their school. The recorded signals - coming from a regional or a worldwide seismic activity - feed an on- line database, which is in fact a real research centre for seismic resources as well as a starting point for educational and scientific activities. The network, that numbers about thirty stations set up in France, in its overseas departments and territories, and in a couple of French schools abroad, is based upon an experience initiated in the French Riviera ten years ago or so. The achievement of the program has from then on gone beyond the simple purpose of conveying seismic data that research and monitoring centres could have recorded. Thanks to the use of scientific measures, students become involved and get into complex notions revolving around geophysics and geosciences. Developing simple tools, setting up concrete experiments combined with an investigate reasoning makes it easier to build up a quality scientific culture as well as an education of citizens to risks.

An inventory of the amphibians of the Reserva Ecológica Michelin - REM in southern Bahia, Brazil is presented. Sixty-nine species were recorded during a ten-year sampling period. Amphibians were distributed in two orders (Gymnophiona and Anura), belonging to twelve families [Aromobatidae (1), Bufonidae (3), Centrolenidae (1), Craugastoridae (5), Eleutherodactylidae (3), Hemiphractidae (2), Hylidae (34), Phyllomedusidae (5) Leptodactylidae (7), Microhylidae (4), Odontophrynidae (3) and Caeciliidae (1)]. Fifty per cent of the reproductive modes known for Atlantic forest anurans were recorded. While no threatened species were found at REM, six species are classified as data deficient (DD) by the Brazilian Red List of threatened species and deserve additional attention. Phasmahyla timbo and Vitreorana eurygnatha are listed as endangered in Bahia according to the list of threatened species of the state. Despite a higher diversity of amphibians in the Atlantic forest having been reported for mountainous regions, our results revealed that amphibian richness for lowland forests is also high.

Guezguez, Mohamed Sadok

Preserving the environment is a major challenge for today's aviation industry. Within this context, the CRIAQ MDO 505 project started, where a multidisciplinary approach was used to improve aircraft fuel efficiency. This international project took place between several Canadian and Italian teams. Industrial teams are Bombardier Aerospace, Thales Canada and Alenia Aermacchi. The academic partners are from Ecole de Technologie Superieure, Ecole Polytechnique de Montreal and Naples University. Teams from 'CIRA' and IAR-NRC research institutes had, also, contributed on this project. The main objective of this project is to improve the aerodynamic performance of a morphing wing prototype by reducing the drag. This drag reduction is achieved by delaying the flow transition (from laminar to turbulent) by performing shape optimization of the flexible upper skin according to different flight conditions. Four linear axes, each one actuated by a 'BLDC' motor, are used to morph the skin. The skin displacements are calculated by 'CFD' numerical simulation based on flow parameters which are Mach number, the angle of attack and aileron's angle of deflection. The wing is also equipped with 32 pressure sensors to experimentally detect the transition during aerodynamic testing in the subsonic wind tunnel at the IAR-NRC in Ottawa. The first part of the work is dedicated to establishing the necessary fieldbus communications between the control system and the wing. The 'CANopen' protocol is implemented to ensure real time communication between the 'BLDC' drives and the real-time controller. The MODBUS TCP protocol is used to control the aileron drive. The second part consists of implementing the skin control position loop based on the LVDTs feedback, as well as developing an automated calibration procedure for skin displacement values. Two 'sets' of wind tunnel tests were carried out to, experimentally, investigate the morphing wing controller effect; these tests also offered the

Introduction Le diabète sucré constitue un véritable problème de santé et ses complications touchent plusieurs organes dont les reins. Un diagnostic précoce de la néphropathie diabétique permet de prendre en charge les patients plus efficacement et de façon multidisciplinaire, de retarder sa progression vers l'insuffisance rénale chronique. Peu d'études ont été faites en Afrique dans ce domaine. Au Tchad, nous ne disposons pas de données statistiques sur l'atteinte rénale liée au diabète. C'est pourquoi nous nous proposons d'étudier la néphropathie diabétique avec pour objectifs d'analyser le profil de la néphropathie diabétique des patients de l'hôpital général de référence nationale de N'Djamena. Méthodes Nous avions mené une étude transversale descriptive à l'Hôpital Générale de Référence Nationale de N'Djamena d'avril à septembre 2012. Etaient inclus dans l'étude tous les patients diabétiques hospitalisés ou suivis dans les services de néphrologie et d'endocrinologie. Résultats Il y avait 54 cas de néphropathie diabétique sur 181 patients soit 29,80%. L'âge de plus de 50 ans représentait 87%, le sexe masculin dominait avec 67%, la durée d'évolution du diabète au moment de la découverte de la néphropathie était de 10,25 ans, la pression artérielle moyenne était de 138 mm Hg, l'HbA1C était supérieur à 6,5% dans 74,5%, l'insuffisance rénale terminale était retrouvée dans 26,90%, une protéinurie à 2,65 g/24 h était détectée dans 60,30%. 57,4% des patients avaient une rétinopathie diabétique au stade III. Conclusion Au Tchad, la fréquence de la néphropathie diabétique est de l'ordre de 29,83%. C'est une affection qui touche les hommes avec une moyenne d'âge de 58,7 ans. Le diabète de type 2 est le plus fréquent avec 90,7% des cas. Les facteurs de risque mal contrôlés pouvaient conduire la néphropathie diabétique vers une altération de la fonction rénale notamment l'HTA (70,8%), un d

In October 2011, the PPMD specialized master's degree students (Photogrammetry, Positionning and Deformation Measurement) of the French ENSG (IGN's School of Geomatics, the Ecole Nationale des Sciences Géographiques) were asked to come and survey the main facade of the cathedral of Amiens, which is very complex as far as size and decoration are concerned. Although it was first planned to use a lift truck for the image survey, budget considerations and taste for experimentation led the project to other perspectives: images shot from the ground level with a long focal camera will be combined to complementary images shot from what higher galleries are available on the main facade with a wide angle camera fixed on a horizontal 2.5 meter long pole. This heteroclite image survey is being processed by the PPMD master's degree students during this academic year. Among other type of products, 3D point clouds will be calculated on specific parts of the facade with both sources of images. If the proposed device and methodology to get full image coverage of the main facade happen to be fruitful, the image acquisition phase will be completed later by another team. This article focuses on the production of 3D point clouds with wide angle images on the rose of the main facade.

The objectives of the present study were to assess the intake of different food groups in French children aged 3-17 years (n 1455), and to analyse trends since a dietary survey undertaken 8 years ago. Dietary intake was evaluated using data from the 2006-7 cross-sectional INCA2 national dietary survey (étude Individuelle Nationale sur les Consommations Alimentaires), based on a 7 d food record. Dietary intake (percentage of subjects consuming the food group and amount eaten) was assessed for thirty-nine food categories. We observed variations in food consumption by age, sex, North-South regional gradient, seasonal period and educational level of the responding parent. Trends in dietary intake between 1999 and 2007 were determined by comparing the INCA1 (n 1126) and the INCA2 surveys. Both surveys had been carried out using the same methodology. The findings showed a decrease in energy intake in children aged 3-14 years, due to a reduction in the consumption of foods of animal origin and sweetened products. In adolescents aged 15-17 years, energy intake remained rather stable; during this 8-year period, the consumption of meat decreased, whereas the consumption of savoury snacks such as sandwiches and hamburgers significantly increased. These trends occurred during a time of growing concern about overweight and the associated co-morbidities in France. A number of public health measures were implemented over this period to improve dietary habits and physical activity patterns in children and adults. The periodic monitoring of dietary patterns through the INCA surveys is an essential part of the surveillance network in France.

In West Africa, as in Majority World countries, people with a communication disability are generally cut-off from the normal development process. A long-term involvement of two partners (Orthophonistes du Monde and Handicap International) allowed the implementation in 2003 of the first speech-language pathology qualifying course in West Africa, within the Ecole Nationale des Auxiliaires Medicaux (ENAM, National School for Medical Auxiliaries) in Lome, Togo. It is a 3-year basic training (after the baccalaureate) in the only academic training centre for medical assistants in Togo. This department has a regional purpose and aims at training French-speaking African students. French speech-language pathology lecturers had to adapt their courses to the local realities they discovered in Togo. It was important to introduce and develop knowledge and skills in the students' system of reference. African speech-language pathologists have to face many challenges: creating an African speech and language therapy, introducing language disorders and their possible cure by means other than traditional therapies, and adapting all the evaluation tests and tools for speech-language pathology to each country, each culture, and each language. Creating an African speech-language pathology profession (according to its own standards) with a real influence in West Africa opens great opportunities for schooling and social and occupational integration of people with communication disabilities.

The orchid bee faunas of two private natural preserves, 'Reserva Particular do Patrimônio Natural da Serra Bonita' (RSB) and 'Reserva Ecológica Michelin' (REM), and a forest fragment inside the campus of the 'Universidade Estadual de Santa Cruz', were surveyed for the first time. All three areas constitute Atlantic Forest remnants in the southern portion of the state of Bahia, Brazil. A total of 1,782 males belonging to 32 species were actively collected with insect nets during 90 hours of field work from November, 2009, to January, 2012. Euglossa cyanochlora Moure, 1996-one of the rarest orchid bee species-was found at RSB and REM, the latter representing the northernmost record for this species. Euglossa cognata, Moure, 1970 was found at RSB, the northernmost record for this species in the Atlantic Forest and the only recent record for this species at the northern border of Jequitinhonha river.

Dans le domaine viscoelastique lineaire (VEL, domaine des petites deformations), le comportement thermomecanique du bitume et du mastic bitumineux (melange uniforme de bitume et de fillers) a ete caracterise au Laboratoire des Chaussees et Materiaux Bitumineux (LCMB) de l'Ecole de technologie superieure (ETS) avec l'appui de nos partenaires externes : la Societe des Alcools du Quebec (SAQ) et Eco Entreprises Quebec (EEQ). Les proprietes rheologiques des bitumes et des mastics ont ete mesurees grâce a un nouvel outil d'investigation appele, Rheometre a Cisaillement Annulaire (RCA), sous differentes conditions de chargement. Cet appareil permet non seulement de solliciter des eprouvettes de tailles importantes par rapport a celles utilisees lors des essais classiques, mais aussi d'effectuer des essais en conditions quasi-homogenes, ce qui permet de donner acces a la loi de comportement des materiaux. Les essais sont realises sur une large gamme de temperatures et de frequences (de -15 °C a 45°C et de 0,03Hz a 10 Hz). Cette etude a ete menee principalement pour comparer le comportement d'un bitume avec celui d'un mastic bitumineux dans le domaine des petites deformations. neanmoins, dans une seconde perspective, on s'interesse a l'influence des fillers de verre de post-consommation sur le comportement d'un mastic a faibles niveaux de deformations en comparant l'evolution des modules complexes de cisaillements (G*) d'un mastic avec fillers de verre et un mastic avec fillers conventionnels (calcaire). Enfin, le modele analogique 2S2P1D est utilise pour simuler le comportement viscoelastique lineaire des bitumes et des mastics bitumineux testes lors de la campagne experimentale.

His grandfather and his father were chemists in Macon. It was then natural for him to adopt such profession. After his studies at the Superior School of Chemistry of Paris (Ecole superieure de pharmacie de Paris), he passed as a first class chemist on december the seventh 1887. His passion for mineralogy, displayed since his youngest years, leads him to frequent scientists specialized in the earth's science, amongst who is Ferdinand Fouque, from the College of France (College de France), whom he used to accompany in his travels through the world between 1888 - the year when he parted from his pharmacy - and 1902. This very year, the eight of may, the terrifying eruption of the montagne Pelee on the isle of la Martinique annihilated in few minutes the town and the port of Saint-Pierre, leaving only two survivors, He sejourned there a second time, in august 1902 after the second eruption. A. Lacroix explained, for the first time, phenomena he designated as nuees ardentes. His knowledge in volcanology and mineralogy made him an expert who has been solicitated to observe various volcanos through out the world. Amongst his principal writings are the treaty of mineralogy (5 vol.), the 2 volumes of his conclusions about his observations of the montagne Pelee and one about the Piton de la Fournaise, to which must be added more than 650 notes and communications. Great officer of the Legion d'Honneur, the chemist Alfred Lacroix, professor at the Museum of natural history since the first of april 1893, carried on the function of perpetual secretary of the Academy of Sciences during 34 years.

To examine the consumption of plain water among children in France and compare total water intakes with guidelines issued by the European Food Safety Authority (EFSA). Nationally representative data were used to assess food, beverage and water consumption by sex, age group (4-8 years, 9-13 years), income-to-poverty ratio, eating occasion and location. Beverages were classified into nine groups: water (tap or bottled), milk, 100 % fruit juice, sodas, fruit drinks, hot beverages, sports drinks and flavoured waters. Total water volume in relation to energy intake (litres/kcal) was also examined. INCA 2 study (Étude Individuelle Nationale des Consommations Alimentaires 2006-2007). French children (n 835) aged 4-13 years. Total water intakes were accounted for by plain water (34 %), beverages (26 %) and food moisture (40 %). Plain water could be tap (18 %) or bottled (16 %). Older children drank more plain water than did younger children and boys drank more plain water than did girls. No socio-economic gradient for plain water consumption was observed. About 90 % of children did not meet the EFSA water intake recommendations. The daily water shortfall ranged from 367 to 594 ml/d. Water-to-energy ratio was 0·75-0·77 litres/1000 kcal (4184 kJ). Children drank milk at breakfast and plain water during lunch and dinner. Caloric beverages provided 10 % of dietary energy; consumption patterns varied by eating location.

In 1870, just after starting medical education in Turkish at the Imperial School of Medicine (Mekeb-i Tibbiye-i Sahani) favor in the pharmacology and surgery courses decreased; and even pharmacology graduates continued their education to be physicians. This change gave rise to the shortage of pharmacists and surgeons in the army, and consquently in 1873 the branch of surgery and in 1876 pharmacology were inaugurated at the Haydarpasa Military Hospital. Those who had studied at this Hospital for three years were given a diploma for pharmacy practice (ameliyat eczaciligi sehadetnamesi) and were appointed to the army and to military hospitals. The years of education was raised to four years in 1888, and it was reduced to three years again in 1891. According to Charles Bonkowski, the chemist of Sultan Abdulhamid II, the instruction of military pharmacology was independent from the School of Medicine; he suggested the foundation of a higher school of pharmacy in Istanbul on the standards of the Paris Higher School of Pharmacology (Ecole Superieur de Pharmacie de Paris) where he had studied and graduated in 1865. Unfortunately this advice was not realised; but a department of pharmacology was opened within the Military High School for Veterinarians (Baytar Rustiye-i Askeriyesi) in Eyup in order to educate the students properly. This institution, renamed as the Military High School for Veterinarians and Pharmacists (Baytar ve Eczact Mekteb-i Rustiye-i Askeriyesi), had sent its graduates to the Imperial School of Medicine for many years. Since this process had proved to be useful, the Pharmacology Branch at the Haydarpasa Military Hospital was closed in 1892. In 1895, another military school which was called Eczaci ve Timarci Sibyan Mektebi started instruction on the Naval Hospital. Graduates of this school were appointed to the naval offices for minor operations.

We consider the scientific potential of gravitational wave (GW) observations in the ~30 mHz to 3 Hz frequency range with the Mid-band Atomic Gravitational-wave Interferometric Sensor (MAGIS). MAGIS is a probe-class space-mission concept, using an atom-based gravitational wave detector, that will provide all-sky strain sensitivities of ~10^-21 sqrt(Hz) and better (1-year) in the GW-frequency mid-band between the LISA/L3 detector (planned 2034 launch) and ground-based Advanced LIGO/Virgo interferometers. Primary gravitational wave astrophysics science in the mid-band include GW observations of the binary black hole population discovered by Advanced LIGO/Virgo at higher-frequencies, prior to their merger stage. For such systems, MAGIS will observe the binaries in their inspiral phase, where system parameters such as eccentricities are most easily constrained, and will provide advanced, degree-scale localizations that would enable electromagnetic observations of possible precursor emission 1-week to 1-month prior to their mergers as well as prompt post-merger transient emission. Joint GW-observations with MAGIS and Advanced LIGO/Virgo covering all stages of binary coalescence will further reduce uncertainties in the GW- localizations and distances, and will be powerful paired with galaxy catalogs, to enable unique galaxy counterpart identifications in the case black hole binary mergers are completely absent of detectable electromagnetic precursor or transient signals. These possibilities for MAGIS extend to neutron star binary systems (black hole - neutron star, neutron star - neutron star), and mid-band prospects for such systems will also be considered.The MAGIS team is a collaboration between institutes in the U.S. including Stanford, AOSense, Harvard, NASA/GSFC, NASA/JPL, NIST, NRL, and UC Berkeley, and international partners at Birmingham, Bordeaux, CNRS, Dusseldorf, Ecole Normale Superieure, Florence, Hannover, and Ulm University.

The Photoloc technique has been employed to measure the state-resolved differential cross sections of the HD(v', j(')) product in the reaction H + D2 over a wide range of collision energies and internal states. The experimental results were compared with fully dimensional, time-dependent quantum mechanical calculations on the refined Boothroyd-Keogh-Martin-Peterson potential energy surface. We find nearly perfect agreement between theory and experiment for HD(v', j(')) product states with low to medium rotational excitation, e.g., HD(v' = 1, j(') = 3) at a collision energy, Ecoll, of 1.72 eV, HD(v' = 1, j(') = 3, 5) at Ecoll = 1.97 eV, and HD(v' = 3, j(') = 3) at Ecoll = 1.97 eV. As the rotational angular momentum, j('), of HD(v', j(')) increases, the agreement between theoretical predictions and experimental measurements worsens but not in a simple fashion. A moderate disagreement between theory and experiment has been found for HD(v' = 0, j(') = 12) at Ecoll = 1.76 eV and increased monotonically for HD(v' = 0, j(') = 13) at Ecoll = 1.74 eV, HD(v' = 0, j(') = 14) at Ecoll = 1.72 eV, and HD(v' = 0, j(') = 15) at Ecoll = 1.70 eV. Disagreement was not limited to vibrationless HD(v', j(')) product states: HD(v' = 1, j(') = 12) at Ecoll = 1.60 eV and HD(v' = 3, j(') = 8, 10) at Ecoll = 1.97 eV followed a similar trend. Theoretical calculations suggest more sideways∕forward scattering than has been observed experimentally for high j(') HD(v', j(')) states. The source of this discrepancy is presently unknown but might be the result of inaccuracy in the potential energy surface.

Such satellites are therefore not only useful for weather fore- casting, but also for the estimation of solar irradiance since the knowledge of the light reflected by clouds is the basis for the calculation of the transmitted light. Additionally an the knowledge of atmospheric parameters involved in scattering and absorption of the sunlight is necessary for an accurate calculation of the solar irradiance. An accurate estimation of the downward solar irradiance is not only of particular im- portance for the assessment of the radiative forcing of the climate system, but also necessary for an efficient planning and operation of solar energy systems. Currently, most of the operational calculation schemes for solar irradiance are semi- empirical. They use cloud information from the current Meteosat satellite and clima- tologies of atmospheric parameters e.g. turbidity (aerosols and water vapor). The Me- teosat Second Generation satellites (MSG, to be launched in 2002) will provide not only a higher spatial and temporal resolution, but also the potential for the retrieval of atmospheric parameters such as ozone, water vapor and with restrictions aerosols. With this more detailed knowledge about atmospheric parameters it is evident to set up a new calculation scheme based on radiative transfer models using the retrieved atmospheric parameters as input. Unfortunately the possibility of deriving aerosol in- formation from MSG data is limited. As a cosequence the use of data from additional satellite instruments ( e.g. GOME/ATSR-2) is neeeded.

Rotational Mode Specificity in the F(-) + CH3Y [Y = F and Cl] SN2 Reactions.

PubMed

Szabó, István; Czakó, Gábor

2015-12-17

More than 12 million quasiclassical trajectories are computed for the F(-) + CH3Y(v = 0, JK) [Y = F and Cl] SN2 reactions using full-dimensional ab initio analytical potential energy surfaces. The initial (J, K = 0) and (J, K = J) [J = 0, 2, 4, 6, 8] rotational state specific cross sections are obtained at different collision energies (Ecoll) in the 1-20 kcal mol(-1) range, and the scattering angle and initial attack angle distributions as well as the mechanism-specific opacity functions are reported at Ecoll = 10 kcal mol(-1). The tumbling rotation (K = 0) inhibits the F(-) + CH3F reaction by a factor of 3 for J = 8 at Ecoll = 10 kcal mol(-1). This tumbling rotational effect becomes smaller at low and high Ecoll, and the tumbling motion affects the cross sections of F(-) + CH3Cl by only a few percent. The spinning rotation (K = J) hinders both reactions by factors in the 1.3-1.7 range for J = 8 at low Ecoll, whereas slight promotion is found as the Ecoll increases. The tumbling rotation may counteract the attractive ion-dipole forces, and the spinning motion hinders the complex formation, thereby decreasing the reactivity.

Prognostic relevance of Fédération Nationale des Centres de Lutte Contre le Cancer grade and MDM2 amplification levels in dedifferentiated liposarcoma: a study of 50 cases.

Dedifferentiated liposarcoma represents a form of liposarcoma composed of a non-lipogenic sarcoma associated with well-differentiated liposarcoma. The prognostic significance of histological grading of the dedifferentiated component remains to be elucidated due to vague grading criteria employed in previous studies. Molecular markers of tumor behavior, including amplification levels of murine double minute-2 (MDM2) and cyclin-dependent kinase-4 (CDK4) genes, have been explored in a limited number of cases. Here we investigate whether 'Fédération Nationale des Centres de Lutte Contre le Cancer' (FNCLCC) grade and MDM2 gene amplification levels have prognostic value in dedifferentiated liposarcoma in terms of local recurrence and disease-specific survival. Fifty cases were retrieved, reviewed and FNCLCC grade was scored for the dedifferentiated component. Testing for MDM2 gene amplification was performed by fluorescence in situ hybridization. Amplification was categorized as high level (≥20 copies) and as low level (<20 copies). Follow-up data was obtained through chart review. Log-rank test and Cox proportional hazard models were used to determine the effect of grade and level of MDM2 amplification on outcomes. Our series includes 50 patients (male n=28, female n=22) with an average age of 63 years (range, 28-88) and a median follow-up of 28 months (range, 2-120). Tumors were graded as grade 1 (6%), grade 2 (58%), and grade 3 (36%). When adjusted for age, sex, site, tumor size, and margin status, grade 3 patients had a higher recurrence rate than grades 1 and 2 (HR=2.07, 95% CI: 1.24, 7.62; P=0.015). Patients with high-level MDM2 amplification had higher recurrence rate on univariate analysis (P=0.028), but not on multivariate analysis (HR=1.69, 95% CI: 0.73, 3.94; P=0.221). FNCLCC grade 3 dedifferentiation confers a worse prognosis in dedifferentiated liposarcoma in terms of local recurrence. MDM2 amplification level remains a useful diagnostic tool in

Cette recherche s'inscrit dans le cadre du projet de recherche Active Control Technology entre l'Ecole de Technologie Superieure et le constructeur Bombardier Aeronautique . Le but est de concevoir des strategies de commandes multivariables et robustes pour des modeles dynamiques d'avions. Ces strategies de commandes devraient assurer a l'avion une haute performance et satisfaire des qualites de vol desirees en l'occurrence, une bonne manoeuvrabilite, de bonnes marges de stabilite et un amortissement des mouvements phugoides et rapides de l'avion. Dans un premier temps, nous nous sommes principalement interesses aux methodes de synthese LTI et plus exactement a l'approche Hinfinity et la mu-synthese. Par la suite, nous avons accorde un interet particulier aux techniques de commande LPV. Pour mener a bien ce travail, nous avons envisage une approche frequentielle, typiquement Hinfinity. Cette approche est particulierement interessante, dans la mesure ou le modele de synthese est construit directement a partir des differentes specifications du cahier des charges. En effet, ces specifications sont traduites sous forme de gabarits frequentiels, correspondant a des ponderations en entree et en sortie que l'on retrouve dans la synthese Hinfinity classique. Par ailleurs, nous avons utilise une representation de type lineaire fractionnelle (LFT), jugee mieux adaptee pour la prise en compte des differents types d'incertitudes, qui peuvent intervenir sur le systeme. De plus, cette representation s'avere tres appropriee pour l'analyse de la robustesse via les outils de la mu-analyse. D'autre part, afin d'optimiser le compromis entre les specifications de robustesse et de performance, nous avons opte pour une structure de commande a 2 degres de liberte avec modele de reference. Enfin, ces techniques sont illustrees sur des applications realistes, demontrant ainsi la pertinence et l'applicabilite de chacune d'elle. Mots cles.

The objective of this nested study was to assess the prevalence of psychiatric disorders in a sample of HIV/hepatitis C virus (HCV)-coinfected patients according to their HCV status. The nested cross-sectional study, untitled HEPAVIH-Psy survey, was performed in a subset of HIV/HCV-coinfected patients enrolled in the French Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS) CO13 HEPAVIH cohort. Psychiatric disorders were screened for using the Mini International Neuropsychiatric Interview (MINI 5.0.0). Among the 286 patients enrolled in the study, 68 (24%) had never received HCV treatment, 87 (30%) were treatment nonresponders, 44 (15%) were currently being treated and 87 (30%) had a sustained virological response (SVR). Of the 286 patients enrolled, 121 patients (42%) screened positive for a psychiatric disorder other than suicidality and alcohol/drug abuse/dependence, 40 (14%) screened positive for alcohol abuse/dependence, 50 (18%) screened positive for drug abuse/dependence, 50 (17.5%) were receiving an antidepressant treatment and 69 (24%) were receiving an anxiolytic. Patients with an SVR did not significantly differ from the other groups in terms of psychiatric disorders. Patients receiving HCV treatment screened positive less often for an anxiety disorder. The highest rate of drug dependence/abuse was among HCV treatment-naïve patients. Psychiatric disorders were frequent in HIV/HCV-coinfected patients and their rates were comparable between groups, even for patients achieving an SVR. Our results emphasize the need for continuous assessment and care of coinfected patients, even after HCV clearance. Drug addiction remains an obstacle to access to HCV treatment. Despite the recent advent and continued development of directly acting antiviral agents (DAAs), it is still crucial to offer screening and comprehensive care for psychiatric and addictive disorders. © 2016 British HIV Association.

Porous silicon substrate is very promising for next generation wireless communication requiring the avoidance of high-frequency losses originating from the bulk silicon. In this work, new variants of porous silicon (PSi) substrates have been introduced. Through an experimental RF performance, the proposed PSi substrates have been compared with different silicon-based substrates, namely, standard silicon (Std), trap-rich (TR) and high resistivity (HR). All of the mentioned substrates have been fabricated where identical samples of CPW lines have been integrated on. The new PSi substrates have shown successful reduction in the substrate's effective relative permittivity to values as low as 3.7 and great increase in the substrate's effective resistivity to values higher than 7 kΩ cm. As a concept proof, a mm-wave bandpass filter (MBPF) centred at 27 GHz has been integrated on the investigated substrates. Compared with the conventional MBPF implemented on standard silicon-based substrates, the measured S-parameters of the PSi-based MBPF have shown high filtering performance, such as a reduction in insertion loss and an enhancement of the filter selectivity, with the joy of having the same filter performance by varying the temperature. Therefore, the efficiency of the proposed PSi substrates has been well highlighted. From 1994 to 1995, she was assistant of physics at (USTHB), Algiers .

Human immunodeficiency virus (HIV)-infected patients are at higher risk of malignancies. In addition to traditional determinants, a specific deleterious effect of HIV and immunodeficiency is speculated. We aimed at studying the association between immunological and virological characteristics of HIV-infected patients in care and the risk of acquired immunodeficiency syndrome (AIDS)-defining and non-AIDS-defining malignancies. Patients consecutively enrolled in the hospital-based Agence Nationale de Recherche sur le Sida (ANRS) CO3 Aquitaine Cohort were included if the duration of follow-up was >3 months during the period 1998-2006. Multivariate modeling used an extended Cox proportional hazards model for time-dependent covariates and delayed entry. The 4194 patients included in the study developed 251 first malignancies during 22,389 person-years. A higher incidence of AIDS-defining malignancies (107 cases) was independently associated with (1) both longer and current exposures to a plasma HIV RNA level >500 copies/mL (hazard ratio [HR], 1.27 per year [P<.001] and 3.30 [P<.001], respectively) and (2) both longer and current exposure to a CD4(+) cell count <200 cells/mm(3) (HR, 1.36 per year [P<.001] and 6.33 [P<.001], respectively). A higher incidence of non-AIDS-defining malignancies (144 cases) was independently associated with longer and current exposure to a CD4(+) cell count <500 cells/mm(3) (HR, 1.13 per year [P=.01] and 2.07 [P<.001], respectively) and male sex (HR, 1.69; P=.02) but not with plasma HIV RNA level (P=.49 and P=.10 for cumulative and current exposures, respectively). Uncontrolled plasma HIV RNA level was independently associated with a higher likelihood of developing AIDS-defining malignancies, whereas immunosuppression was associated with a higher risk of developing any type of malignancies. Antiretroviral treatment should aim at reaching and maintaining a CD4(+) count >500 cells/mm(3) to prevent the occurrence of malignancy, this should be

It has been extensively shown, mainly in US populations, that sugar-sweetened beverages (SSBs) are associated with increased risk of type 2 diabetes (T2D), but less is known about the effects of artificially sweetened beverages (ASBs). We evaluated the association between self-reported SSB, ASB, and 100% fruit juice consumption and T2D risk over 14 y of follow-up in the French prospective Etude Epidémiologique auprès des femmes de la Mutuelle Générale de l'Education Nationale-European Prospective Investigation into Cancer and Nutrition cohort. A total of 66,118 women were followed from 1993, and 1369 incident cases of T2D were diagnosed during the follow-up. Cox regression models were used to estimate HRs and 95% CIs for T2D risk. The average consumption of sweetened beverages in consumers was 328 and 568 mL/wk for SSBs and ASBs, respectively. Compared with nonconsumers, women in the highest quartiles of SSB and ASB consumers were at increased risk of T2D with HRs (95% CIs) of 1.34 (1.05, 1.71) and 2.21 (1.56, 3.14) for women who consumed >359 and >603 mL/wk of SSBs and ASBs, respectively. Strong positive trends in T2D risk were also observed across quartiles of consumption for both types of beverage (P = 0.0088 and P < 0.0001, respectively). In sensitivity analyses, associations were partly mediated by BMI, although there was still a strong significant independent effect. No association was observed for 100% fruit juice consumption. Both SSB consumption and ASB consumption were associated with increased T2D risk. We cannot rule out that factors other than ASB consumption that we did not control for are responsible for the association with diabetes, and randomized trials are required to prove a causal link between ASB consumption and T2D.

Privacy Laws and Biobanking in Germany.

Hoppe, Nils

2016-03-01

While the possibility of enacting a sui generis Biobank Act has been debated in Germany at great length, as of yet the country has not implemented any biobankspecific legislation. Instead, oversight is available via a network of research and privacy laws, including those of the European Union. The Nationale Kohorte, Germany's large-scale, population-based epidemiological research biobank, is funded by the Federal Ministry of Education and Research, and there are currently 108 registered bio-banks throughout Germany. The current system, including the structure and study design of the Nationale Kohorte, privileges the protection of personal information even at the cost of socially desirable research; it remains to be seen if forthcoming legislation will shift this balance. © 2016 American Society of Law, Medicine & Ethics.

To compare the diagnostic performance of qualitative shear-wave elastography (SWE) according to three different color map opacities for breast masses 101 patients aged 21-77 years with 113 breast masses underwent B-mode US and SWE under three different color map opacities (50%, 19% and 100%) before biopsy or surgery. Following SWE features were reviewed: visual pattern classification (pattern 1-4), color homogeneity (Ehomo) and six-point color score of maximum elasticity (Ecol). Combined with B-mode US and SWE, the likelihood of malignancy (LOM) was also scored. The area under the curve (AUC) was obtained by ROC curve analysis to assess the diagnostic performance under each color opacity. A visual color pattern, Ehomo, Ecol and LOM scoring were significantly different between benign and malignant lesions under all color opacities (P<0.001). For 50% opacity, AUCs of visual color pattern, Ecol, Ehomo and LOM scoring were 0.902, 0.951, 0.835 and 0.975. But, for each SWE feature, there was no significant difference in the AUC among three different color opacities. For all color opacities, visual color pattern and Ecol showed significantly higher AUC than Ehomo. In addition, a combined set of B-mode US and SWE showed significantly higher AUC than SWE alone for color patterns, Ehomo, but no significant difference was found in Ecol. Qualitative SWE was useful to differentiate benign from malignant breast lesion under all color opacities. The difference in color map opacity did not significantly influence diagnostic performance of SWE. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Contribution au developpement d'une methode de controle des procedes dans une usine de bouletage

Gosselin, Claude

This thesis, a collaborative effort between Ecole de technologie superieure and ArcelorMittal Company, presents the development of a methodology for monitoring and quality control of multivariable industrial production processes. This innovation research mandate was developed at ArcelorMittal Exploitation Miniere (AMEM) pellet plant in Port-Cartier (Quebec, Canada). With this undertaking, ArcelorMittal is striving to maintain its world class level of excellence and continues to pursue initiatives that can augment its competitive advantage worldwide. The plant's gravimetric classification process was retained as a prototype and development laboratory due to its effect on the company's competitiveness and its impact on subsequent steps leading to final production of iron oxide pellets. Concretely, the development of this expertise in process control and in situ monitoring will establish a firm basic knowledge in the fields of complex system physical modeling, data reconciliation, statistical observers, multivariate command and quality control using real-time monitoring of the desirability function. The hydraulic classifier is mathematically modeled. Using planned disturbances on the production line, an identification procedure was established to provide empirical estimations of the model's structural parameters. A new sampling campaign and a previously unpublished data collection and consolidation policy were implemented plant-wide. Access to these invaluable data sources has enabled the establishment of new thresholds that govern the production process and its control. Finally, as a substitute for the traditional quality control process, we have implemented a new strategy based on the use of the desirability function. Our innovation is not in using this Finally, as a substitute for the traditional quality control process, we have implemented a new strategy based on the use of the desirability function.

Since 1974 Portugal has experienced some dramatic changes in educational practices at the local level. The school has been opened to the community and the community to the school. Teacher education now includes community studies, designed to prepare teachers for an active role in this process and for the better understanding of the social background of pupils. One new practice is the publication of local newspapers or news-sheets to enhance the understanding of the community by teachers and pupils. The development of a school garden for the cultivation of flowers and vegetables serves as another bridge between school and community. Other examples of community action are adult literacy classes, the creation of voluntary organisations for women, the running of youth clubs, the formation of co-operatives, and local projects like the purchase of an old tram-car to be converted into a library. The introduction of `Civic and Polytechnic Education' for 13-16 year olds was an important innovation. One half-day a week was to be devoted to the integration of the school with the locality, young people's participation in society as agents of change, the linking of study and productive work, and the involvement of young people in the solution of national problems, working from a concrete knowledge of local and regional life. However, since 1976 there has been a more conservative approach, and only in places with a strong consensus amongst teachers has the new relationship between school and community been maintained.

Do gray wolves (Canis lupus) support pack mates during aggressive inter-pack interactions?

PubMed

Cassidy, Kira A; McIntyre, Richard T

For group-living mammals, social coordination increases success in everything from hunting and foraging (Crofoot and Wrangham in Mind the Gap, Springer, Berlin, 2010; Bailey et al. in Behav Ecol Sociobiol 67:1-17, 2013) to agonism (Mosser and Packer in Anim Behav 78:359-370, 2009; Wilson et al. in Anim Behav 83:277-291, 2012; Cassidy et al. in Behav Ecol 26:1352-1360, 2015). Cooperation is found in many species and, due to its low costs, likely is a determining factor in the evolution of living in social groups (Smith in Anim Behav 92:291-304, 2014). Beyond cooperation, many mammals perform costly behaviors for the benefit of group mates (e.g., parental care, food sharing, grooming). Altruism is considered the most extreme case of cooperation where the altruist increases the fitness of the recipient while decreasing its own fitness (Bell in Selection: the mechanism of evolution. Oxford University Press, Oxford 2008). Gray wolf life history requires intra-pack familiarity, communication, and cooperation in order to succeed in hunting (MacNulty et al. in Behav Ecol doi: 10.1093/beheco/arr159 2011) and protecting group resources (Stahler et al. in J Anim Ecol 82: 222-234, 2013; Cassidy et al. in Behav Ecol 26:1352-1360, 2015). Here, we report 121 territorial aggressive inter-pack interactions in Yellowstone National Park between 1 April 1995 and 1 April 2011 (>5300 days of observation) and examine each interaction where one wolf interferes when its pack mate is being attacked by a rival group. This behavior was recorded six times (17.6 % of interactions involving an attack) and often occurred between dyads of closely related individuals. We discuss this behavior as it relates to the evolution of cooperation, sociality, and altruism.

We develop a full-dimensional global analytical potential energy surface (PES) for the F(-) + CH3F reaction by fitting about 50 000 energy points obtained by an explicitly correlated composite method based on the second-order Møller-Plesset perturbation-F12 and coupled-cluster singles, doubles, and perturbative triples-F12a methods and the cc-pVnZ-F12 [n = D, T] basis sets. The PES accurately describes the (a) back-side attack Walden inversion mechanism involving the pre- and post-reaction (b) ion-dipole and (c) hydrogen-bonded complexes, the configuration-retaining (d) front-side attack and (e) double-inversion substitution pathways, as well as (f) the proton-abstraction channel. The benchmark quality relative energies of all the important stationary points are computed using the focal-point analysis (FPA) approach considering electron correlation up to coupled-cluster singles, doubles, triples, and perturbative quadruples method, extrapolation to the complete basis set limit, core-valence correlation, and scalar relativistic effects. The FPA classical(adiabatic) barrier heights of (a), (d), and (e) are -0.45(-0.61), 46.07(45.16), and 29.18(26.07) kcal mol(-1), respectively, the dissociation energies of (b) and (c) are 13.81(13.56) and 13.73(13.52) kcal mol(-1), respectively, and the endothermicity of (f) is 42.54(38.11) kcal mol(-1). Quasiclassical trajectory computations of cross sections, scattering (θ) and initial attack (α) angle distributions, as well as translational and internal energy distributions are performed for the F(-) + CH3F(v = 0) reaction using the new PES. Apart from low collision energies (Ecoll), the SN2 excitation function is nearly constant, the abstraction cross sections rapidly increase with Ecoll from a threshold of ∼40 kcal mol(-1), and retention trajectories via double inversion are found above Ecoll = ∼ 30 kcal mol(-1), and at Ecoll = ∼ 50 kcal mol(-1), the front-side attack cross sections start to increase very rapidly.

Microsatellite Analysis for Identification of Individuals Using Bone from the Extinct Steller's Sea Cow (Hydrodamalis gigas).

Warner, Jeffery F; Harpole, Michael G; Crerar, Lorelei D

2017-01-01

Microsatellite DNA can provide more detailed population genetic information than mitochondrial DNA which is normally used to research ancient bone. The methods detailed in this chapter can be utilized for any type of bone. However, for this example, four microsatellite loci were isolated from Steller's sea cow (Hydrodamalis gigas) using published primers for manatee and dugong microsatellites. The primers DduC05 (Broderick et al., Mol Ecol Notes 6:1275-1277, 2007), Tmakb60, TmaSC5 (Pause et al., Mol Ecol Notes 6: 1073-1076, 2007), and TmaE11 (Garcia-Rodriguez et al., Mol Ecol 12:2161-2163, 2000) all successfully amplified microsatellites from H. gigas. The DNA samples were from bone collected on Bering or St. Lawrence Islands. DNA was analyzed using primers with the fluorescent label FAM-6. Sequenced alleles were then used to indicate a difference in the number of repeats and thus a difference in individuals. This is the first time that H. gigas microsatellite loci have been isolated. These techniques for ancient bone microsatellite analysis allow an estimate of population size for a newly discovered St. Lawrence Island sea cow population.

Calibrating a Soil-Vegetation-Atmosphere system with a genetical algorithm

NASA Astrophysics Data System (ADS)

Schneider, S.; Jacques, D.; Mallants, D.

2009-04-01

Accuracy of model prediction is well known for being very sensitive to the quality of the calibration of the model. It is also known that quantifying soil hydraulic parameters in a Soil-Vegetation-Atmosphere (SVA) system is a highly non-linear parameter estimation problem, and that robust methods are needed to avoid the optimization process to lead to non-optimal parameters. Evolutionary algorithms and specifically genetic algorithms (GAs) are very well suited for those complex parameter optimization problems. The SVA system in this study concerns a pine stand on a heterogeneous sandy soil (podzol) in the north of Belgium (Campine region). Throughfall and other meteorological data and water contents at different soil depths have been recorded during one year at a daily time step. The water table level, which is varying between 95 and 170 cm, has been recorded with a frequency of 0.5 hours. Based on the profile description, four soil layers have been distinguished in the podzol and used for the numerical simulation with the hydrus1D model (Simunek and al., 2005). For the inversion procedure the MYGA program (Yedder, 2002), which is an elitism GA, was used. Optimization was based on the water content measurements realized at the depths of 10, 20, 40, 50, 60, 70, 90, 110, and 120 cm to estimate parameters describing the unsaturated hydraulic soil properties of the different soil layers. Comparison between the modeled and measured water contents shows a good similarity during the simulated year. Impacts of short and intensive events (rainfall) on the water content of the soil are also well reproduced. Errors on predictions are on average equal to 5%, which is considered as a good result. A.

Introduction Il s'agit d'analyser la prise en charge du nouveau-né dans le cadre de la stratégie na-tionale de subvention des accouchements et des soins obstétricaux et néonatals d'urgence mis en place par le gouvernement du Burkina Faso en 2006. Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. Conclusion La subvention a amélioré la prise en charge du nouveau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. PMID:26161166

Oxidation Dynamics of Methionine with Singlet Oxygen: Effects of Methionine Ionization and Microsolvation.

PubMed

Liu, Fangwei; Liu, Jianbo

2015-06-25

We report an in-depth study on the gas-phase reactions of singlet O2[a(1)Δg] with methionine (Met) at different ionization and hydration states (including deprotonated [Met - H](-), hydrated deprotonated [Met - H](-)(H2O)1,2, and hydrated protonated MetH(+)(H2O)1,2), using guided-ion-beam scattering mass spectrometry. The measurements include the effects of collision energy (Ecol) on reaction cross sections over a center-of-mass Ecol range from 0.05 to 1.0 eV. The aim of this study is to probe the influences of Met ionization and hydration on its oxidation mechanism and dynamics. Density functional theory calculations, Rice-Ramsperger-Kassel-Marcus modeling, and quasi-classical, direct dynamics trajectory simulations were performed to examine the properties of various complexes and transition states that might be important along reaction coordinates, probe reaction potential energy surfaces, and to establish the atomic-level mechanism for the Met oxidation process. No oxidation products were observed for the reaction of [Met - H](-) with (1)O2 due to the high-energy barriers located in the product channels for this system. However, this nonreactive property was altered by the microsolvation of [Met - H](-); as a result, hydroperoxides were captured as the oxidation products for [Met - H](-)(H2O)1,2 + (1)O2. For the reaction of MetH(+)(H2O)1,2 + (1)O2, besides formation of hydroperoxides, an H2O2 elimination channel was observed. The latter channel is similar to what was found in the reaction of dehydrated MetH(+) with (1)O2 (J. Phys. Chem. B 2011, 115, 2671). The reactions of hydrated protonated and deprotonated Met are all inhibited by Ecol, becoming negligible at Ecol ≥ 0.5 eV. The kinetic and dynamical consequences of microsolvation on Met oxidation and their biological implications are discussed.

Pierre-François Nicolas, was born in Saint-Mihiel in 1743, studied in this town and in St-Nicolas-de-Port near Nancy. At first he has been a military apothecary during the "Guerre de Sept-Ans". Then he studied pharmacy in Nancy and was received in 1768 at the "Maîtrise de pharmacie". With the physician Henri Michel du Tennatar, he created a teaching of chemistry for medicine students and became the professor of chemistry of the Faculty of Medicine in 1781. During these years, he published some research results about hydrology, distillery, biochemistry (phosphorus in bone), toxicology, dyeing... At the end of 1783, he succeeded in the realization of a balloon and he played an important part in Nancy during the French Revolution. Professor at the "Ecole de médecine" in Strasbourg for some weeks, then in Nancy at the "Ecole centrale" and at the "Société de santé", he left Nancy towards the mid-1798. Staying in Paris for two or three years he probably worked with Fourcroy and perhaps Chaptal and Berthollet. In the early years of the nineteenth century he was appointed professor in the "Ecole centrale" du Calvados" and some years after at the "Faculté des sciences" in Caen. His latest significant work with Gueudeville was devoted to the detection of sugar in the urine of diabetic patients. Retired in 1811 Pierre-François Nicolas died in Caen in 1816.

Energy Scaling of Cold Atom-Atom-Ion Three-Body Recombination

We study three-body recombination of Ba++Rb +Rb in the mK regime where a single 138Ba+ ion in a Paul trap is immersed into a cloud of ultracold 87Rb atoms. We measure the energy dependence of the three-body rate coefficient k3 and compare the results to the theoretical prediction, k3∝Ecol-3 /4, where Ecol is the collision energy. We find agreement if we assume that the nonthermal ion energy distribution is determined by at least two different micromotion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed in an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s -wave regime.

Genetic diversity and differentiation patterns in Micromeria from the Canary Islands are congruent with multiple colonization dynamics and the establishment of species syngameons.

PubMed

Curto, M; Puppo, P; Kratschmer, S; Meimberg, H

2017-08-22

Especially on islands closer to the mainland, such as the Canary Islands, different lineages that originated by multiple colonization events could have merged by hybridization, which then could have promoted radiation events (Herben et al., J Ecol 93: 572-575, 2005; Saunders and Gibson, J Ecol 93: 649-652, 2005; Caujapé-Castells, Jesters, red queens, boomerangs and surfers: a molecular outlook on the diversity of the Canarian endemic flora, 2011). This is an alternative to the scenario where evolution is mostly driven by drift (Silvertown, J Ecol 92: 168-173, 2004; Silvertown et al., J Ecol 93: 653-657, 2005). In the former case hybridization should be reflected in the genetic structure and diversity patterns of island species. In the present work we investigate Micromeria from the Canary Islands by extensively studying their phylogeographic pattern based on 15 microsatellite loci and 945 samples. These results are interpreted according to the hypotheses outlined above. Genetic structure assessment allowed us to genetically differentiate most Micromeria species and supported their current classification. We found that populations on younger islands were significantly more genetically diverse and less differentiated than those on older islands. Moreover, we found that genetic distance on younger islands was in accordance with an isolation-by-distance pattern, while on the older islands this was not the case. We also found evidence of introgression among species and islands. These results are congruent with a scenario of multiple colonizations during the expansion onto new islands. Hybridization contributes to the grouping of multiple lineages into highly diverse populations. Thus, in our case, islands receive several colonization events from different sources, which are combined into sink populations. This mechanism is in accordance with the surfing syngameon hypothesis. Contrary to the surfing syngameon current form, our results may reflect a slightly different

LONG-TERM DYNAMICS OF RADIONUCLIDE VERTICAL MIGRATION IN SOILS OF THE CHERNOBYL NUCLEAR POWER PLANT EXCLUSION ZONE

DOE Office of Scientific and Technical Information (OSTI.GOV)

Farfan, E

2009-11-19

The radioactive fallout from the Chernobyl Nuclear Power Plant (ChNPP) accident consisted of fuel and condensation components. An important radioecological task associated with the late phase of the accident is to evaluate the dynamics of radionuclide mobility in soils. Identification of the variability (or invariability) in the radionuclide transfer parameters makes it possible to (1) accurately predict migration patterns and biological availability of radionuclides and (2) evaluate long-term exposure trends for the population who may reoccupy the remediated abandoned areas. In 1986-1987, a number of experimental plots were established within various tracts of the fallout plume to assist with themore » determination of the long-term dynamics of radionuclide vertical migration in the soils. The transfer parameters for {sup 137}Cs, {sup 90}Sr, and {sup 239,240}Pu in the soil profile, as well as their ecological half-time of the radionuclide residence (T{sub 1/2}{sup ecol}) values in the upper 5-cm thick soil layers of different grasslands were estimated at various times since the accident. Migration characteristics in the grassland soils tend to decrease as follows: {sup 90}Sr > {sup 137}Cs {ge} {sup 239,240}Pu. It was found that the {sup 137}Cs absolute T{sub 1/2}{sup ecol} values are 3-7 times higher than its radioactive decay half-life value. Therefore, changes in the exposure dose resulting from the soil deposited {sup 137}Cs now depend only on its radioactive decay. The {sup 90}Sr T{sub 1/2}{sup ecol} values for the 21st year after the fallout tend to decrease, indicating an intensification of its migration capabilities. This trend appears consistent with a pool of mobile {sup 90}Sr forms that grows over time due to destruction of the fuel particles.« less

To evaluate the interobserver agreement and the diagnostic performance of various qualitative features in shear-wave elastography (SWE) for breast masses. A total of 153 breast lesions in 152 women who underwent B-mode ultrasound and SWE before biopsy were included. Qualitative analysis in SWE was performed using two different classifications: E values (Ecol; 6-point color score, Ehomo; homogeneity score and Esha; shape score) and a four-color pattern classification. Two radiologists reviewed five data sets: B-mode ultrasound, SWE, and combination of both for E values and four-color pattern. The BI-RADS categories were assessed B-mode and combined sets. Interobserver agreement was assessed using weighted κ statistics. Areas under the receiver operating characteristic curve (AUC), sensitivity, and specificity were analyzed. Interobserver agreement was substantial for Ecol (κ=0.79), Ehomo (κ=0.77) and four-color pattern (κ=0.64), and moderate for Esha (κ=0.56). Better-performing qualitative features were Ecol and four-color pattern (AUCs, 0.932 and 0.925) compared with Ehomo and Esha (AUCs, 0.857 and 0.864; P<0.05). The diagnostic performance of B-mode ultrasound (AUC, 0.950) was not significantly different from combined sets with E value and with four color pattern (AUCs, 0.962 and 0.954). When all qualitative values were negative, leading to downgrade the BI-RADS category, the specificity increased significantly from 16.5% to 56.1% (E value) and 57.0% (four-color pattern) (P<0.001) without improvement in sensitivity. The qualitative SWE features were highly reproducible and showed good diagnostic performance in suspicious breast masses. Adding qualitative SWE to B-mode ultrasound increased specificity in decision making for biopsy recommendation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Quantifying long-term risks to sea otters from the 1989 'Exxon Valdez' oil spill: reply to Harwell & Gentile (2013)

USGS Publications Warehouse

Ballachey, Brenda E.; Bodkin, James L.; Monson, Daniel H.

2013-01-01

Recovery of sea otter populations in Prince William Sound (PWS), Alaska, has been delayed for more than 2 decades following the 1989 ‘Exxon Valdez’ oil spill. Harwell & Gentile (2013; Mar Ecol Prog Ser 488:291–296) question our conclusions in Bodkin et al. (2012; Mar Ecol Prog Ser 447:273-287) regarding adverse effects that oil lingering in the environment may have on sea otters. They agree that exposure may continue, but disagree that it constitutes a significant risk to sea otters. In Bodkin et al. (2012), we suggested that subtle effects of chronic exposure were the most reasonable explanation for delayed recovery of the sea otter population in areas of western PWS, where shorelines were most heavily oiled. Here, we provide additional information on the ecology of sea otters that clarifies why the toxicological effects of oral ingestion of oil do not reflect all effects of chronic exposure. The full range of energetic, behavioral, and toxicological concerns must be considered to appraise how chronic exposure to residual oil may constrain recovery of sea otter populations.

PREFACE: 6th International Conference on Inverse Problems in Engineering: Theory and Practice

NASA Astrophysics Data System (ADS)

Bonnet, Marc

2008-07-01

The 6th International Conference on Inverse Problems in Engineering: Theory and Practice (ICIPE 2008) belongs to a successful series of conferences held up to now following a three-year cycle. Previous conferences took place in Palm Coast, Florida, USA (1993), Le Croisic, France (1996), Port Ludlow, Washington, USA (1999), Angra dos Reis, Brazil (2002), and Cambridge, UK (2005). The conference has its roots on the informal seminars organized by Professor J V Beck at Michigan State University, which were initiated in 1987. The organization of this Conference, which took place in Dourdan (Paris) France, 15-19 June 2008, was made possible through a joint effort by four research departments from four different universities: LEMTA (Laboratoire de Mécanique Théorique et Appliquée, Nancy-Université) LMS (Laboratoire de Mécanique des Solides, Ecole Polytechnique, Paris) LMAC (Laboratoire de Mathématiques Appliquées, UTC Compiègne) LTN (Laboratoire de Thermocinétique, Université de Nantes) It received support from three organizations: SFT (Société Française de Thermique: French Heat Transfer Association) ACSM (Association Calcul de Structures et Simulation : Computational Structural Mechanics Association) GdR Ondes - CNRS (`Waves' Network, French National Center for Scientific Research) The objective of the conference was to provide the opportunity for interaction and cross-fertilization between designers of inverse methods and practitioners. The delegates came from very different fields, such as applied mathematics, heat transfer, solid mechanics, tomography.... Consequently the sessions were organised along mostly methodological topics in order to facilitate interaction among participants who might not meet otherwise. The present proceedings, published in the Journal of Physics: Conference Series, gathers the four plenary invited lectures and the full-length versions of 103 presentations. The latter have been reviewed by the scientific committee (see

Fixedwing UAV soundings of the boundary layer during the ScaleX 2015 summer campaign in southern Germany

2016-04-01

In order to examine the potential to close the local water cycle budget and to evaluate models on different scales (among other aims) a fleet of 6 fixed wing UAVs has been operated by the Institute for Geography and the Institute for Informatics of the University of Augsburg during the ScaleX measurement campaign of the KIT/IMK-IFU (Karlsruher Institut für Technologie/Institut für Meteorologie und Klimatologie, Garmisch Partenkirchen). The site is located in southern Germany in a rural, hilly landscape at a small catchment tributing to the Ammersee and equipped with several ground based and remote sensing hydrological instruments. In order to complement these instruments by in situ measurements of the boundary layer, three intensive observation periods (IOPs) for taking temperature and humidity profiles took place, each with a different set up in order to evaluate optimal operation modes. The UAVs are all operated by the open hardware Apogee autopilot and sensor controller developed by ENAC (Ecole Nationale de l'Aviation Civile, Toulouse) operated by the PPRZ open source software package. The first IOP (30.06.-01.07.2015) was an experiment to cover a small site of 500 by 500 meters (well-apointed with hydrological instruments) in a 24 hours period as dense as possible. Thus three simultaneous helical profile flights (radius 70 m) have been run at each full hour around three different centres with heights ranging up to 1000 m above ground level (with special permissions). During a second IOP (15.07.2015) it has been tried to increase the frequence of profile flights up to 2 flights per hours between 7:30 and 14:00 CEST. These soundings have been accompanied by flyovers of a manned ultra light aircraft of the IMK-IFU. Finally a third experiment (06.08.2015) tried to evaluate longer flights (up to 55 minutes) of two UAVs at constant levels of 300 and 500 m above ground level between 6:00 and 14:00 CEST in order to cover the early diurnal cycle even more constantly

Crush-2: Communicating research through a science-art collaboration

NASA Astrophysics Data System (ADS)

Mair, K.; Barrett, N.; Schubnel, A. J.; Abe, S.

2011-12-01

Historically, the Earth's environment and dynamics have influenced and inspired the arts. Art in turn is a powerful vehicle for expression of the natural world. It lends itself to public presentation in many forms and appeals to a diverse audience. Science-art collaborations provide a unique opportunity to connect with the public by taking science out of the classroom and into museums, galleries and public spaces. Here we investigate the use of contemporary digital sound-art in communicating geoscience research to the general public through the installation Crush-2. Crush-2, is an interactive sound-art installation exploring the microscopic forces released during the crushing of rock. Such processes have a strong influence on the sliding behaviour and hence earthquake potential of active faults. This work is a collaboration between sound artist and composer Natasha Barrett (Oslo) and geoscientists Karen Mair (University of Oslo), Alexandre Schubnel (Ecole Normale Superieure, Paris) and Steffen Abe (RWTH Aachen). Using a sonification technique, Barrett has assigned sound recorded from rocks, of different pitches, timbres and durations, to individual fracturing events produced in our 3D fault fragmentation models and laboratory rock breaking experiments. In addition, ultrasonic acoustic emissions recorded directly in the laboratory are made audible for our hearing and feature in the work. The installation space comprises a loudspeaker array and sensor enabled helmet with wireless headphones. By wearing the helmet, moving and listening, the audience explores an artistic interpretation of the scientific data in physical space. On entering the space, one is immediately immersed in a 3D cacophony of sound. Sustained or intermittent pings, burrs, plops and tingles jostle for position in our heads whilst high pitched delicate cascades juxtapose with deep thunder like rumbles. Depending on the user's precise path through the soundscape, the experience changes accordingly

Neurologic complications of post-partum are serious and usually secondary to eclampsia or stroke. We here report a 26-year-old female who presented with severe headaches, blurred vision, and repeated generalized seizures secondary to posterior reversible encephalopathy that occurred after a caesarean section for fetal death in utero. Outcome was favourable. Although uncommon, this neurologic complication of the post-partum should be discussed in the presence of any sign of encephalopathy occurring in the context of acute hypertension.

Myeloproliferative disorders and secondary polycythemia cover most of the polycythemia cases encountered in daily practice. Inherited polycythemias are rare entities that have to be suspected when the classical causes of acquired polycythemia have been ruled out. Recent advances were made in the understanding of these pathologies, which are still little known to the physicians. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of inherited polycythemia.

Pachymeningitis is a fibrosing and inflammatory process, which involves the dura mater. Some pachymeningitis are cranial and induce headaches and cranial nerve palsies. Others are spinal and responsible for nerve roots or spinal cord compression. MRI shows contrast enhancement thickening of the dura mater. Etiologies are infectious (syphilis, tuberculosis, etc.) or inflammatory (sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease, idiopathic). Corticosteroids are the main treatment. The use of immunosuppressive drugs or rituximab is yet to be determined and probably adapted to each etiology. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Hydrogeological Investigations in Deep Wells at the Meuse/Haute Marne Underground Research Laboratory

NASA Astrophysics Data System (ADS)

Delay, Jacques; Distinguin, Marc

ANDRA (Agence Nationale pour la Gestion de Déchets Radioactifs) has developed an integrated approach to characterizing the hydrogeology of the carbonate strata that encase the Callovo-Oxfordian argillite at the Meuse/Haute-Marne Laboratory site. The argillites are difficult to characterize due to their low permeability. The barrier properties of the argillites can be inferred from the flow and chemistry properties of the encasing Oxfordian and Dogger carbonates. Andras deep hole approach uses reverse air circulation drilling, geophysical logging, flow meter logging, geochemical sampling, and analyses of the pumping responses during sampling. The data support numerical simulations that evaluate the argillites hydraulic behaviour.

The topological phase diagram of cimetidine: A case of overall monotropy.

Cimetidine is a histamine H 2 -receptor antagonist used against peptic ulcers. It is known to exhibit crystalline polymorphism. Forms A and D melt within 0.35 degrees from each other and the enthalpies of fusion are similar as well. The present paper demonstrates how to construct a pressure-temperature phase diagram with only calorimetric and volumetric data available. The phase diagram provides the stability domains and the phase equilibria for the phases A, D, the liquid and the vapor. Cimetidine is overall monotropic with form D the only stable solid phase.

A systematic approach is needed to enable a rapid diagnosis and an appropriate treatment. Pleural fluid analysis is the first step to perform which allows a presumptive diagnosis in most cases. Otherwise, further analysis of the pleural fluid or thoracic imaging or pleural biopsy may be necessary.

Le Laser A Argon Ionise : Applications Therapeutiques

Le laser a argon ionise est un laser a emission continue, reglee en general en multiraies de 487 a 544 nm. Le rayonnement de ce laser est bien absorbe par les tissus vivants, avec une action preferentielle au niveau des pigments rouges (hemoglobine, myoglobine) et noirs (melanine). Le laser a argon est princi-palement utilise en therapeutique pour ses effets thermiques : en fonction du choix des parametres (puissance optique, surface exposee, temps d'exposition) on peut obtenir une coagulation (temperature optimale au niveau des tissus 60° - 80°) ou une volatisation (temperature superieure a 100°). Si la zone volatilisee est tres etroite (inferieure a 0,5 mm) on obtient un effet de coupe. Par rapport aux deux autres lasers egalement utilises pour leurs effets thermiques (CO2 et Nd. YAG) l'argon a des effets intermediaires : la coagulation sera plus superficielle qu'avec le Nd. YAG et la volatisation plus profonde qu'avec le CO2. Lors de la coupe, la necrose sur les berges sera egalement plus importante qu'avec le CO2.

The non-statistical dynamics of the 18O + 32O2 isotope exchange reaction at two energies

2014-08-01

The dynamics of the 18O(3P) + 32O2 isotope exchange reaction were studied using crossed atomic and molecular beams at collision energies (Ecoll) of 5.7 and 7.3 kcal/mol, and experimental results were compared with quantum statistical (QS) and quasi-classical trajectory (QCT) calculations on the O3(X1A') potential energy surface (PES) of Babikov et al. [D. Babikov, B. K. Kendrick, R. B. Walker, R. T. Pack, P. Fleurat-Lesard, and R. Schinke, J. Chem. Phys. 118, 6298 (2003)]. In both QS and QCT calculations, agreement with experiment was markedly improved by performing calculations with the experimental distribution of collision energies instead of fixed at the average collision energy. At both collision energies, the scattering displayed a forward bias, with a smaller bias at the lower Ecoll. Comparisons with the QS calculations suggest that 34O2 is produced with a non-statistical rovibrational distribution that is hotter than predicted, and the discrepancy is larger at the lower Ecoll. If this underprediction of rovibrational excitation by the QS method is not due to PES errors and/or to non-adiabatic effects not included in the calculations, then this collision energy dependence is opposite to what might be expected based on collision complex lifetime arguments and opposite to that measured for the forward bias. While the QCT calculations captured the experimental product vibrational energy distribution better than the QS method, the QCT results underpredicted rotationally excited products, overpredicted forward-bias and predicted a trend in the strength of forward-bias with collision energy opposite to that measured, indicating that it does not completely capture the dynamic behavior measured in the experiment. Thus, these results further underscore the need for improvement in theoretical treatments of dynamics on the O3(X1A') PES and perhaps of the PES itself in order to better understand and predict non-statistical effects in this reaction and in the formation

1995-01-01

Since the 1960s the French public school system has virtually abandoned the attempt to teach moral values, leaving students morally disoriented. The author finds this situation profoundly unhealthy and argues that schools have a responsibility to help in developing the ability of pupils to make moral choices and act accordingly. He rejects the rationalist view that science makes traditional morality unnecessary. At the same time, he recognizes the moral value of the scientific respect of truth and objectivity. He argues for a form of moral education which would inculcate respect for different points of view, cultural norms and religious beliefs, and which would not shy away from addressing morally important issues such as drag abuse, violence, sexuality, social justice, poverty, racism and environmental pollution.

Evolutionary medicine represents an innovative approach deriving from evolutionary biology. It includes the initial Darwin's view, its actualization in the light of progresses in genetics and also dissident theories (i.e. non gene-based) particularly epigenetics. This approach enables us to reconsider the pathophysiology of numerous diseases, as for instance, infection, and our so-called diseases of civilization especially obesity, type 2 diabetes, allergy or cancer. Evolutionary medicine may also improve our knowledge regarding inter-individual variation in susceptibility to disease or drugs. Furthermore, it points out the impact of our behaviors and environment on the genesis of a series of diseases. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Hereditary angioedema is a rare disease, often diagnosed with delay because of a heterogeneous clinical presentation. Before diagnosis, patients frequently present subcutaneous edema or abdominal pains during many years. Laryngeal edema can be life-threatening. Hereditary angioedema may impair the quality of life of the patients and their social and professional life. It is important that the physicians recognize and treat the disease as soon as possible after the first attacks. Since the past five years, new drugs developed for hereditary angioedema have changed dramatically the outcome of this disorder. The objective of this review is to detail the new therapeutic guidelines. Copyright © 2012 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Several cases of hearing loss induced by hydroxychloroquine have been reported in the literature but the role of hydroxychloroquine still remains debated. We report the first case, to our knowledge, of hearing loss induced by hydroxychloroquine with a positive re challenge in a woman treated for systemic lupus. An analysis of the French pharmacovigilance database allowed to identify 23 additional cases of hearing loss in patients treated with hydroxychloroquine and, among them, 8 had systemic lupus. Despite an excellent tolerance and high efficacy-side effect ratio, this case report adds some evidence for an otoxicity of hydroxychloroquine.

Antineutrophil cytoplasmic antibodies (ANCA) associated with infective endocarditis are a rare disorder. The condition can mimic primary systemic vasculitis (i.e. granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). Thus, a wrong diagnosis of valvular involvement related to primary systemic vasculitis can be made in patients exhibiting ANCA associated with infective endocarditis. Because treatment of both conditions is different, this wrong diagnosis will lead to dramatic consequences in these latter patients. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of ANCA associated with infective endocarditis.

Steeper declines in forest photosynthesis than respiration explain age-driven decreases in forest growth.

The traditional view of forest dynamics originated by Kira and Shidei [Kira T, Shidei T (1967) Jap J Ecol 17:70-87] and Odum [Odum EP (1969) Science 164(3877):262-270] suggests a decline in net primary productivity (NPP) in aging forests due to stabilized gross primary productivity (GPP) and continuously increased autotrophic respiration (Ra). The validity of these trends in GPP and Ra is, however, very difficult to test because of the lack of long-term ecosystem-scale field observations of both GPP and Ra. Ryan and colleagues [Ryan MG, Binkley D, Fownes JH (1997) Ad Ecol Res 27:213-262] have proposed an alternative hypothesis drawn from site-specific results that aboveground respiration and belowground allocation decreased in aging forests. Here, we analyzed data from a recently assembled global database of carbon fluxes and show that the classical view of the mechanisms underlying the age-driven decline in forest NPP is incorrect and thus support Ryan's alternative hypothesis. Our results substantiate the age-driven decline in NPP, but in contrast to the traditional view, both GPP and Ra decline in aging boreal and temperate forests. We find that the decline in NPP in aging forests is primarily driven by GPP, which decreases more rapidly with increasing age than Ra does, but the ratio of NPP/GPP remains approximately constant within a biome. Our analytical models describing forest succession suggest that dynamic forest ecosystem models that follow the traditional paradigm need to be revisited.

Etude de la transmission sonore a travers un protecteur de type "coquilles" : modelisation numerique et validation experimentale

NASA Astrophysics Data System (ADS)

Boyer, Sylvain

On estime que sur les 3,7 millions des travailleurs au Quebec, plus de 500 000 sont exposes quotidiennement a des niveaux de bruits pouvant causer des lesions de l'appareil auditif. Lorsqu'il n'est pas possible de diminuer le niveau de bruit environnant, en modifiant les sources de bruits, ou en limitant la propagation du son, le port de protecteurs auditifs individualises, telles que les coquilles, demeure l'ultime solution. Bien que vue comme une solution a court terme, elle est communement employee, du fait de son caractere peu dispendieux, de sa facilite d'implantation et de son adaptabilite a la plupart des operations en environnement bruyant. Cependant les protecteurs auditifs peuvent etre a la fois inadaptes aux travailleurs et a leur environnement et inconfortables ce qui limite leur temps de port, reduisant leur protection effective. Afin de palier a ces difficultes, un projet de recherche sur la protection auditive intitule : " Developpement d'outils et de methodes pour ameliorer et mieux evaluer la protection auditive individuelle des travailleur ", a ete mis sur pied en 2010, associant l'Ecole de technologie superieure (ETS) et l'Institut de recherche Robert-Sauve en sante et en securite du travail (IRSST). S'inscrivant dans ce programme de recherche, le present travail de doctorat s'interesse specifiquement a la protection auditive au moyen de protecteurs auditifs " passifs " de type coquille, dont l'usage presente trois problematiques specifiques presentees dans les paragraphes suivants. La premiere problematique specifique concerne l'inconfort cause par exemple par la pression statique induite par la force de serrage de l'arceau, qui peut reduire le temps de port recommande pour limiter l'exposition au bruit. Il convient alors de pouvoir donner a l'utilisateur un protecteur confortable, adapte a son environnement de travail et a son activite. La seconde problematique specifique est l'evaluation de la protection reelle apportee par le protecteur. La

Archean Pb Isotope Evolution: Implications for the Early Earth.

Vervoort, J. D.; Thorpe, R.; Albarede, F.; Blichert-Toft, J.

2008-12-01

The U-Pb isotope system provides us with a powerful tool for understanding the chemical evolution of the Earth. Pb isotopes in Archean rocks, however, have not been widely utilized because U mobility makes initial Pb isotope ratios from old silicate rocks difficult, if not impossible, to determine. Galenas in syngenetic volcanogenic massive sulfide (VMS) deposits, however, provide snapshots of initial Pb ratios because their Pb isotopic composition is time invariant at their formation (U/Pb=0). The Pb isotopic record from galenas from rocks of all age have been utilized for over 70 years to answer a wide range of scientific problems beginning with Al Nier's pioneering work analyzing Pb isotopes in the 1930's but are no longer widely used by the isotopic community because they have been produced by older TIMS techniques. We have begun a re-examination of Archean Pb by an extensive analysis of over 100 galena samples from Archean VMS deposits throughout the Superior and Slave Provinces in Canada as well as from other VMS deposits in Finland, South Africa and Western Australia. The goal of this work is to provide modern, high precision measurements and update an old, but venerable, Pb isotopic data set. We feel these data provide important constraints on not only the Pb isotopic evolution of the Earth, but planetary differentiation and recycling processes operating in the first 2 b.y. of Earth's history. Our analytical techniques include dissolving the Pb sulfide minerals, purifying them with ion chromatography, and analyzing them using MC-ICPMS at both Washington State University (Neptune) and Ecole Normale Superieure in Lyon, France (Nu). All Pb solutions are doped with Tl in order to correct for mass fractionation. In this abstract we report preliminary galena Pb isotope data from 6 VMS deposits in the Abitibi greenstone belt: Chibougamu, Matagami, Noranda, Normetal, Timmins, and Val d"Or. These deposits are all approximately 2.7 Ga in age but in detail vary from 2

This article was written by four French hospital director students at the Ecole des Hautes Etudes en Santé Publique (EHESP-School of Public Health) from a study conducted jointly with students at the Grenoble School of Management to present an international overview of hospital procurement methods in ten countries. An analysis of these methods showed that there was a general trend towards group purchasing, with some common aims in terms of costs and performance and some differences in legislation (competition), size of the public sector and centralization or decentralization.

Amyloidosis is mainly a systemic disease belonging to protein-folding diseases. The past 10 years have shown significant progress in typing and the clinical management of amyloidosis, in the identification of novel prognostic markers for risk-stratification, and also in the development of new therapeutic agents. Biological molecular techniques are now able to type amyloidosis which were unidentified. Cardiac MRI and biomarkers allow a precise risk-stratification, especially in AL amyloidosis. If necessary, this prognostic evaluation may lead to rapid changes in the chemotherapy treatment. Emerging treatments rely on biotherapies, gene therapy, immunotherapy and blocking analogous agents. They give hope about an increase of survival of patients with systemic amyloidosis. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

[Sarcoidosis flare after autologous stem cell transplantation: An immune paradox?

PubMed

2017-09-01

Sarcoidosis is a systemic granulomatous disorder of unknown cause. Apparition or flare of previously diagnosed sarcoidosis following hematopoietic stem cell transplantation (HSCT) has rarely been reported. We report a 62-year-old woman who presented a radiological flare of sarcoidosis post-autologous stem cell transplantation for a POEMS syndrome. Imaging findings and lymph node histology, which revealed non-caseating granuloma, were consistent with the sarcoidosis diagnosis. The patient was asymptomatic and was kept free of treatment. Sarcoidosis must be considered ahead of compatible clinicoradiological presentation occurring after HSCT. Sarcoidosis can mimic metastatic cancer or lymphatic relapse. Tissue biopsies and exclusion of differential diagnosis of granuloma diseases are warranted to confirm sarcoidosis diagnosis. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Electric-field control of spin waves in multiferroic BiFeO3: Theory

2011-03-01

Our recent experiment demonstrated gigantic (30%) electric-field tuning of magnon frequencies in multiferroic BiFeO3. We demonstrate that the origin of this effect is related to two linear magnetoelectric interactions that couple the component of electric field perpendicular to the ferroelectric vector to a quadratic form of the Néel vector. We calculate the magnon spectra due to each of these interactions and show that only one of them is consistent with experimental data. At high electric fields, this interaction induces a phase transition to a homogeneous state, and the multi-magnon spectra will fuse into two magnon frequencies. We discuss the possible microscopic mechanisms responsible for this novel interaction and the prospect for applications in magnonics. We acknowledge support from NSERC-Discovery (Canada) and the Agence Nationale pour la Recherche (France).

Approximately 1.5% of dementia is due to curable aetiology. We report an isolated dementia syndrome due to a meningeal relapse of acute promyelocytic leukaemia with favourable outcome after appropriate treatment. A 72-year-old woman, in remission of an acute promyelocytic leukaemia, presented a loss of autonomy for several months due to corticosubcortical dementia. Lumbar puncture showed blast cells indicating meningeal relapse of leukaemia. Intrathecal chemotherapy and arsenic trioxide obtained biological and molecular remission as well as restoration of normal cognitive functions. In patients with hematologic past history such as acute promyelocytic leukaemia, an isolated cognitive impairment should alert physicians to search for an isolated neuromeningeal relapse.

From dipolar to multipolar interactions between ultracold Feshbach molecules

NASA Astrophysics Data System (ADS)

Quéméner, Goulven; Lepers, Maxence; Luc-Koenig, Eliane; Dulieu, Olivier

2016-05-01

Using the multipolar expansion of electrostatic and magnetostatic potential energies, we characterize the long-range interactions between two weakly-bound diatomic molecules, taking as an example the paramagnetic Er2 Feshbach molecules which were produced recently. The interaction between atomic magnetic dipoles gives rise to the usual R-3 leading term of the multipolar expansion, where R is the intermolecular distance. We show that additional terms scaling as R-5, R-7 and so on also appear, which are strongly anisotropic with respect to the orientation of the molecules. These terms can be seen as effective molecular multipole moments reflecting the spatial extension of the molecules which is non-negligible compared to R. We acknowledge the financial support of the COPOMOL project (ANR-13-IS04-0004) from Agence Nationale de la Recherche.

Postural tachycardia syndrome (PoTS) is a multifactorial syndrome defined by an increase in heart rate ≥30bpm, within 10minutes of standing (or during a head up tilt test to at least 60°), in absence of orthostatic hypotension. It is associated with symptoms of cerebral hypoperfusion that are worse when upright and improve in supine position. Patients have an intense fatigue with a high incidence on quality of life. This syndrome can be explained by many pathophysiological mechanisms. It can be associated with Ehlers-Danlos disease and some autoimmune disorders. The treatment is based on nonpharmacological measures and treatment with propranolol, fludrocortisone or midodrine. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

[National ethics committees and representative democracy: is the new German ethics committee more "democratic"?].

PubMed

Dagron, Stéphanie

2007-01-01

The bill passed in April 2007 by the German parliament aims to confer democratic legitimacy on the German Ethics Committee (deutscher Ethikrat) which has replaced the former National Ethics Committee (nationaler Ethikrat) set up in 2001. This law results from a wide debate which began in 2005 within the political parties about the role in democracy of the bodies charged with advising the people's representatives in the areas of biotechnology and modern medicine. In this article, the author explains why it was necessary to confer a certain democratic legitimacy on the new Ethics Committee and analyses the relation that exists between the democratic principle, the work of this type of committee and the national institutional structure retained to stimulate the debate and advise the political decision-makers, and even to prepare legislation concerning bioethics.

Soil biotic legacy effects of extreme weather events influence plant invasiveness

Climate change is expected to increase future abiotic stresses on ecosystems through extreme weather events leading to more extreme drought and rainfall incidences [Jentsch A, et al. (2007) Front Ecol Environ 5(7):365–374]. These fluctuations in precipitation may affect soil biota, soil processes [Evans ST, Wallenstein MD (2012) Biogeochemistry 109:101–116], and the proportion of exotics in invaded plant communities [Jiménez MA, et al. (2011) Ecol Lett 14:1277–1235]. However, little is known about legacy effects in soil on the performance of exotics and natives in invaded plant communities. Here we report that drought and rainfall effects on soil processes and biota affect the performance of exotics and natives in plant communities. We performed two mesocosm experiments. In the first experiment, soil without plants was exposed to drought and/or rainfall, which affected soil N availability. Then the initial soil moisture conditions were restored, and a mixed community of co-occurring natives and exotics was planted and exposed to drought during growth. A single stress before or during growth decreased the biomass of natives, but did not affect exotics. A second drought stress during plant growth resetted the exotic advantage, whereas native biomass was not further reduced. In the second experiment, soil inoculation revealed that drought and/or rainfall influenced soil biotic legacies, which promoted exotics but suppressed natives. Our results demonstrate that extreme weather events can cause legacy effects in soil biota, promoting exotics and suppressing natives in invaded plant communities, depending on the type, frequency, and timing of extreme events.

An experimental program of neutron transport studies of the Lithium Blanket Module (LBM) is being carried out with the LOTUS point-neutron source facility at Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. Preliminary experiments use passive neutron dosimetry within the fuel rods in the LBM central zone, as well as, both thermal extraction and dissolution methods to assay tritium bred in Li/sub 2/O diagnostic wafers and LBM pellets. These measurements are being compared and reconciled with each other and with the predictions of two-dimensional discrete-ordinates and continuous-energy Monte-Carlo analyses of the Lotus/LBM system.

Lemierre's syndrome is a rare and severe sepsis that can rapidly lead to a life-threatening condition in the absence of early management. This syndrome described at the beginning of the 20th century combines oropharyngeal infection complicated with septic thrombosis of the internal jugular vein and septic emboli predominantly pulmonary. Fusobacterium necrophorum, anaerobic germ, Gram negative bacillus is the main germ in this "necrobacillosis". The diagnosis is should be confirmed precociously with cervicothoracic CT-scan, reference exam, and bacteriological examinations (especially in atypical forms). Its management consists of an emergency antibiotic treatment, combining a third-generation cephalosporin or a betalactam with metronidazole, anticoagulant therapy to be reserved for high-risk situations related to thrombosis. Surgical treatment may be required. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Hemorrhoids are a common medical problem that is often considered as benign. The French Society of Colo-Proctology (Société nationale française de colo-proctologie [SNFCP]) recently revised its recommendations for the management of hemorrhoids (last issued in 2001), based on the literature and consensual expert opinion. We present a short report of these recommendations. Briefly, medical treatment, including dietary fiber, should always be proposed in first intention and instrumental treatment only if medical treatment fails, except in grade ≥III prolapse. Surgery should be the last resort, and the patient well informed of the surgical alternatives, including the possibility of elective ambulatory surgery, if appropriate. Postoperative pain should be prevented by the systematic implementation of a pudendal block and multimodal use of analgesics. Copyright © 2016. Published by Elsevier Masson SAS.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder. Drug-induced TTP is uncommon and we report a TTP associated with the use of clopidogrel. We report a 50-year-old man who presented with acute myocardial infarction and received clopidogrel therapy. He developed acute TTP ten days after clopidogrel onset. Imputability of the drug was demonstrated during a reintroduction test. Deficiency of ADAMTS 13 was confirmed and autoantibodies against ADAMTS 13 were detected. Complete remission was obtained after 24 plasma exchange sessions and adjunction of corticosteroids. Drug-induced TTP are probably immunologic, as was demonstrated in our patient. Clinicians should be aware of this possible uncommon adverse effect of clopidogrel because prompt therapy is imperative for life saving.

2015-05-01

Thrombotic microangiopathies (TMA) define a syndrome characterized by the association of microangiopathic haemolytic anaemia with schistocytes, peripheral thrombocytopenia, and organ injury of variable severity. Thrombotic thrombocytopenic purpura (TTP) and atypical haemolytic uremic syndrome (HUS) are the main forms of TMA. Recent advances in the pathophysiology of those two diseases, which include in HUS the identification of a deregulation of the alternative complement pathway, and in TTP a severe deficiency in ADAMTS-13, allowed to develop specific, pathophysiology-based therapies. Therefore, rituximab and eculizumab tends to be increasingly used, and there is an urgent need to define consensual modes of administration at the international level, as well as common definitions of response evaluation and follow-up explorations.

2017-05-01

Organophosphorus coumpounds (OP) are toxic chemicals mainly used for agricultural purpose such as insecticides and were also developed and used as warfare nerve agents. OP are inhibitors of acetylcholinesterase, a key enzyme involved in the regulation of the central nervous system. Chemical, physical and biological approaches have been considered to decontaminate OP. This review summarizes the current and emerging strategies that are investigated to tackle this issue with a special emphasis on enzymatic remediation methods. During the last decade, many studies have been dedicated to the development of biocatalysts for OP removal. Among these, recent reports have pointed out the promising enzyme SsoPox isolated from the archaea Sulfolobus solfataricus. Considering both its intrinsic stability and activity, this hyperthermostable enzyme is highly appealing for the decontamination of OP. Copyright © 2017 Académie Nationale de Pharmacie.

Mondor's disease is a rare superficial thrombophlebitis, historically involving the thoracic venous system of women. However, it can occur in both gender and all over the skin. We report a 40-year-old man with type one diabetes who presented with a thrombosis of the superficial dorsal vein of the penis that he treated as a fungal infection. Treatment with non-steroidal anti-inflammatory drugs and low molecular weight heparin contributed to a favorable outcome in 2 weeks. Pathogenesis and treatment of Mondor's disease remain incompletely dominated. Some predisposing factors have been highlighted in the literature. It might be interesting to add diabetes, due to its frequent pelvic problems leading to a potential venous inflammatory trigger.

It contains more than 56 000 small molecules and natural compounds synthesised or isolated in different laboratories over the past years. This explains the diversity of the collection. The strength of this initiative is the ability to connect chemists and biologists for the development of hits. This development involves the synthesis of analogues or/and chemical tools to find new targets. These collaborations lead to the identification of new chemical probes. These probes able to modulate a biological function are essential to study biological pathways. They can also be useful for therapeutic applications.

The heart involvement in systemic sclerosis is frequent and can touch various sites. The prognosis in the presence of heart disease is poor, but few data are available about its management. We report the case of 48 years old woman with systemic sclerosis which presented severe heart involvement. She has severe heart failure, supraventricular arrhythmias and symptomatic pericarditis, which required surgical intervention and immunosuppressive drugs (steroids with rituximab). Despite this treatment, she has persistent severe heart impaired function and intravenous immunoglobulins have been initiated. She experienced progressively the improvement of dyspnea, of heart systolic ejection fraction and decrease of Rodnan scale. Our case illustrates a severe heart involvement in systemic sclerosis which have been improved by intravenous immunoglobulins.

Organizational Strategies for Critical Transportation Infrastructure: Characteristics of Urban Resilience. The Case of Montreal. Stéphane Beauregard M.Sc. Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

The complexity of urban hydrology results both from that of urban systems and the extreme rainfall variability. The latter can display strongly localised rain cells that can be extremely damaging when hitting vulnerable parts of urban systems. This paper investigates this complexity on a semi-urban sub-catchment - located in Massy (South of Paris, France) - of the Bievre river, which is known for its frequent flashfloods. Advanced geo-processing techniques were used to find the ideal pixel size for this 6.326km2 basin. C-band and X-band radar data are multifractally downscaled at various resolutions and input to the fully distributed hydrological model Multi-Hydro. The latter has been developed at Ecole des Ponts ParisTech. It integrates validated modules dealing with surface flow, saturated and unsaturated surface flow, and sewer flow. The C-band radar is located in Trappes, approx. 21km East of the catchment, is operated by Méteo-France and has a resolution of 1km x 1km x 5min. The X-band radar operated by Ecole des Ponts Paris Tech on its campus has a resolution of 125m x 125m x 3.4min. The performed multifractal downscaling enables both the generation of large ensemble realizations and easy change of resolution (e.g. down to 10 m in the present study). This in turn allows a detailed analysis of the impacts of small scale variability and the required resolution to obtain accurate simulations, therefore predictions. This will be shown on two rainy episodes over the chosen sub-catchment of the Bievre river.

Entreprendre une recherche sur la politique et la législation en matière d'éducation des adultes, qui couvre plusieurs secteurs, paraît une gageure pour plusieurs raisons: difficultés dans la constitution de plusieurs équipes de recherche avec plusieurs spécialistes ou personnes ressources, difficultés dans la collecte des données, étendue et complexité des domaines à explorer et des points à prendre en compte dans la rédaction, etc. En dépit de ces difficultés majeures, l'essentiel du travail a été accompli dans le souci de respecter les exigences imposées. A l'analyse, nous constatons que plusieurs partenaires interviennent dans la formation, l'éducation et l'encadrement des adultes, et que dans le secteur public, les structures ne sont pas "logées à la même enseigne": Si la formation professionnelle a bénéficié de conditions réellement favorables pour son expansion et son développement, les autres secteurs, sans avoir été négligés, n'ont pas connu les mêmes faveurs. Ainsi plusieurs lois et mesures importantes ont été votées et prises en vue de la dynamisation de la formation professionnelle, alors que le secteur de l'agriculture, qui est la base de succès du développement du pays et occupe 55% de la population, n'a pas bénéficié d'une véritable politique éducative en faveur des agriculteurs. Il en est de même pour l'alphabétisation. On déplore constamment l'absence de politique élaborée et appliquée à l'échelle nationale. Aucune mesure politique n'a été votée par l'Assemblée nationale, alors que l'alphabétisation devrait constituer le levier du développement de l'éducation des adultes en Côte d'lvoire.

Such conditions leave no clear indication of the pre-Variscan metamorphic grade in the basement, a parameter probably most important in the thermal modelling.

In a joint study by students from the Ecole Polytechnique Feminine, France, and the University of California, Los Angeles, a mission concept that had the objective of evaluating the feasibility of a non-nuclear, yet fast, manned mission to Mars was considered. Ion-engine propelled tankers are postulated that would provide mid-coarse refueling of LOX and LH2 to the manned ship. The scenario is therefore one of a 'split mission', yet with the added feature that the cargo ships include tankers for mid-course refueling. The present study is a continuation of one first conducted last year. Emphasis this year was on the design of the tanker fleet.

Recently, we have successfully created an ultracold sample of absolute ground-state NaRb molecules by two-photon Raman transfer of weakly bound Feshbach molecules. Here we will present the detailed spectroscopic investigations on both the excited and the rovibrational ground states for finding the two-photon path. For the excited state, we focus on the A1Σ+ /b3 Π singlet and triplet admixture. We discovered an anomalously strong coupling between the Ω =0+ and 0- components which renders efficient population transfer possible. In the ground state, the pure nuclear hyperfine levels have been clearly resolved, which allows us to create molecules in the absolute ground state directly with Raman transfer. This work is jointly supported by Agence Nationale de la Recherche (#ANR-13- IS04-0004-01) and Hong Kong Research Grant Council (#A-CUHK403/13) through the COPOMOL project.

Bovine ketosis is a rare cause of metabolic acidosis. It is a starvation ketosis that appears in lactating woman. A 29-year-old woman had a previous gastric surgery one month ago while breastfeeding her 6-month child. She presented to emergency with dyspnea, fatigue, weight loss and anorexia. The explorations revealed a serious metabolic acidosis with a high anion gap, for which all other causes have been eliminated. A restrictive diet in lactating patients is a major risk of ketosis or bovine ketosis. Medico-surgical treatment of obesity during lactation seems unreasonable. Breastfeeding should be systematically sought before a medical and surgical management of obesity. With the spread of bariatric surgery, starvation ketosis is a cause of metabolic acidosis not to ignore. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

Céolin, R; Rietveld, I-B

2016-01-01

After a short review of the controversies surrounding the discovery of crystalline polymorphism in relation to our present day understanding, the methods of how to solve the stability hierarchy of different polymorphs will be briefly discussed. They involve either theoretical calculations, or, more commonly, experimental methods based on classical thermodynamics. The experimental approach is mainly carried out using heat-exchange data associated to the transition of one form into another. It will be demonstrated that work-related data associated to the phase transition should be taken into account and the role of X-ray crystallography therein will be discussed. X-ray crystallography has become increasingly precise and can nowadays provide specific volumes and their differences as a function of temperature, and also as a function of pressure, humidity, and time.

Kennedy, William James; Bilotte, Michel; Melchior, Patrice

2015-12-01

The Turonian successions of the southern Corbieres comprise three transgressive-regressive cycles in which ammonites occur in three intervals. The lowest comes from the glauconitic basal transgressive unit of the first cycle, and comprises 21 species, including Kamerunoceras douvillei (Pervinquiere, 1907), Kamerunoceras turoniense (d'Orbigny, 1850), Spathites (Jeanrogericeras) revelerianus (Courtiller, 1860), Spathites (Jeanrogericeras) combesi (d'Orbigny, 1856), Mammites nodosoides (Schluter, 1871), Mammites powelli Kennedy, Wright and Hancock, 1987, Fagesia tevestensis (Peron, 1896), Neoptychites cephalotus (Coutiller, 1860), Thomasites rollandi (Thomas and Peron, 1889), Wrightoceras wallsi Reyment, 1954, and Choffaticeras (Choffaticeras) quaasi (Peron, 1904). This is a Lower Turonian assemblage referred to the Mammites nodosoides Zone, although the possibility that elements from the preceding Fagesia catinus Zone are also present cannot be excluded. The fauna from the transgressive glauconitic interval of the succeeding cycle comprises nine species, including Romaniceras (Romaniceras) mexicanum Jones, 1938, Romaniceras (Yubariceras) ornatissimum (Stoliczka, 1864), Pseudotissotia galliennei (d'Orbigny, 1850), Collignoniceras woollgari (Mantell, 1822) sensu lato, Coilopoceras springeri Hyatt, 1903, and Eubostrychoceras (Eubostrychoceras) saxonicum (Schluter, 1872). They indicate the Middle Turonian Romaniceras (R.) mexicanum and R. (Y.) ornatissimum zones. The highest fauna, from the Marnes superieurs de Saint-Louis of the Saint-Louis syncline, is: Subprionocyclus sp. juv., Prionocyclus sp. and Worthoceras cf. rochatianum (d'Orbigny, 1850). The Subprionocyclus are minute individuals that resemble S. bravaisianus (d'Orbigny, 1841), and suggest the presence of the lower Upper Turonian bravaisianus Zone.

Engaging people in environmental studies is an important way to bring across awareness of expected future climate changes, and also a way to measure environmental change in ways that are better or complementary to remote sensing methods. With a hands-on approach, people are more likely to embrace the idea that climate change is occurring, and with modern technologies it is possible to collect quite stunning amounts of relevant data. We suggest several national activities tailored to conditions in each of the participating countries and also to existing national CO-projects. The project focuses on gathering data on biological changes, on weather, and on snow-pack information in Nordic countries as well as Greenland and Canada. Data will be gathered with existing equipment (mobile phones and internet-connected weather stations) and the project provides the means for collation of data into a database for dissemination and quality control. Numerical data collected by small non-professional weather stations or mobile phones with sensors are not directly useful quantitatively for e.g. numerical weather prediction without validation of data quality, but with validation there is a huge untapped potential due to the number of observers. Students are a central part of the project, which also seeks to engage people out and about in nature, and people with their own weather stations or other environmental data-collection activities, as well as passive data collection from mobile phone data sensors in people's bags and pockets. Appropriate software, educational and training materials will be designed with end-users in mind; school-age materials will be produced in the appropriate languages (e.g. Kalaallisut for COs of school age in Greenland).

Dynamically Consistent Shallow-Atmosphere Equations with a Complete Coriolis force Marine Tort1, Thomas Dubos1, François Bouchut2 & Vladimir Zeitlin1,3 1 Laboratoire of Dynamical Meteorology, Univ. P. and M. Curie, Ecole Normale Supérieure, and Ecole Polytechnique, FRANCE 2 Université Paris-Est, Laboratoire d'Analyse et de Mathématiques Appliquées, FRANCE 3 Institut Universitaire de France Atmospheric and oceanic motion are usually modeled within the shallow-fluid approximation, which simplifies the 3D spherical geometry. For dynamical consistency, i.e. to ensure conservation laws for potential vorticity, energy and angular momentum, the horizontal component of the Coriolis force is neglected. Here new equation sets combining consistently a simplified shallow-fluid geometry with a complete Coriolis force is presented. The derivation invokes Hamilton's principle of least action with an approximate Lagrangian capturing the small increase with height of the solid-body entrainment velocity due to planetary rotation. A three-dimensional compressible model and a one-layer shallow-water model are obtained. The latter extends previous work done on the f-plane and β-plane. Preliminary numerical results confirm the accuracy of the 3D model within the range of parameters for which the equations are relevant. These new models could be useful to incorporate a full Coriolis force into existing numerical models and to disentangle the effects of the shallow-atmosphere approximation from those of the traditional approximation.

Remote entanglement stabilization for modular quantum computing

NASA Astrophysics Data System (ADS)

Didier, Nicolas; Shankar, S.; Mirrahimi, M.

Quantum information processing in a modular architecture requires to distribute and stabilize entanglement in a qubit network. We present autonomous entanglement stabilization protocols between two qubits that are coupled to distant cavities. The cavities coupling is mediated and controlled via a three-wave mixing device that generates either a delocalized mode or a two-mode squeezed state between the remote cavities depending on the pump frequency. Local drives on the qubits and the cavities steer and maintain the system to the desired qubit Bell state. We show that these reservoir-engineering based protocols stabilize entanglement in presence of qubit-cavity asymmetries and losses. Most spectacularly, even a weakly-squeezed state can stabilize a maximally entangled Bell state of two distant qubits through entanglement accumulation.

Opsoclonus-myoclonus-ataxia (OMS) is a rare clinical syndrome, of paraneoplastic infectious, post-infectious, post-vaccinal or idiopathic origin. We report a 24-year-old young man who presented with gait disorder preceded by a febrile rash and retroauricular lymph nodes. Three days before admission, he had headache, vertigo, nausea and vomiting followed by gait unsteadiness and movement disorders of limbs and eyes. On examination, he had OMS syndrome. Brain MRI, total body scan, MIBG scintigraphy, tumor markers and onconeural antibodies were normal. Cerebro-spinal fluid (CSF) analysis showed lymphocytic meningitis. Positive serum and CSF immunoglobulin M antibody against rubella virus was demonstrated. He received acyclovir with full recovery within two weeks. We discuss the peculiarities of this association with a literature review. This observation enlarges the spectrum of neurological manifestations of rubella as well as that of OMS etiologies.

3D printing plays an increasingly important role in the medical sector and particularly in surgery. Nowadays, numerous manufacturers benefit from this technology to produce their medical devices and some hospitals have also purchased 3D printers. In this context, the aim of the present study was to study the distribution and the use of 3D printing in French hospitals in order to its main features in surgery. By conducting a national survey, we targeted hospitals equipped with 3D printers and those using external providers to benefit from this technology. Forty-seven hospitals were identified as using 3D printing including eight equipped with in-house 3D printers. This work gives us a first picture of 3D printing for hospital use in France and it raises questions about hospital pharmacists' involvement in 3D printed medical device production.

Bioinformatics and chemoinformatics approaches contribute to the discovery of novel targets, chemical probes, hits, leads and medicinal drugs. A vast repertoire of computational methods has indeed been reported over the years and in this review, I will briefly introduce some concepts and approaches, namely the analysis of potential therapeutic target binding pockets, the preparation of compound collections and virtual screening. An example of application is provided for two proteins acting in the blood coagulation system. Overall, in silico methods have been shown to improve R and D productivity in both, academic settings and in the private sector, if they are integrated in a rational manner with experimental approaches. However, integration of tools and pluridisciplinarity are seldom achieved. Efforts should be done in this direction as pluridisciplinarity and a true acknowledgment of all the contributing actors along the value chain could enhance innovation and reduce skyrocketing costs.

Infection by human parvovirus B19 (erythrovirus B19) is common and usually asymptomatic during childhood conferring lasting protection against a new infection. Parvovirus B19 infection may cause erythema infectiosum (5th disease) and aplastic crisis. Secondary symptomatic parvovirus B19 infection in the same patient is rare and its physiopathology is not always clear. A 48-year-old HIV-infected female patient presented within 5 years two acute episodes of parvovirus B19 infection although her CD4 cells count was above 500/mm(3). Absence of specific antibodies production after the first episode and persisting parvovirus viremia suggested viral reactivation rather than re-infection. During the second episode, specific antibodies were produced. Similarly to most DNA viruses, parvovirus B19 reactivation is possible in HIV-infected patients while effectively treated by antiretroviral therapy.

Listeriosis is a food-borne illness leading to bacteriemia or central nervous system infection especially in pregnant women or high-risk patients. It is rarely a localized infection. Breast contamination has rarely been reported in lactating women. We report a breast abscess in man. A 80 year old man, hypertensive and arrhythmic, was explored for weakness and dehydration. Type 2 diabetes and chronic lymphocytic leukemia were diagnosed. Clinical examination disclosed a breast abcess related to L monocytogenes infection. Histopathological study also revealed a breast subcutaneous infiltration by chronic lymphocytic leukemia. Listeriosis sometimes uncover an unknown immunosuppression, especially in the elderly. Breast is a non-sterile tissue containing a stable microbiome partly from digestive origin. It can thereby be contaminated by Listeria. The specific cutaneous infiltrate of chronic lymphocytic leukemia can create the conditions for a local infection. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

High oxygen affinity hemoglobins.

PubMed

Mangin, O

2017-02-01

High oxygen affinity hemoglobins are responsible for rare and heterogeneous autosomic dominant genetic diseases. They cause pure erythrocytosis, sometimes accountable for hyperviscosity and thrombosis, or hemolysis. Differential diagnoses must be first ruled out. The diagnosis is based on the identification of a decreased P50, and their possible characterization by cation exchange-high performance liquid chromatography and capillary electrophoresis. Finally, genetic studies of the responsible globin chain gene will confirm the mutation. The prognosis mainly relies on the P50 decrease rate and on the hemoglobin cooperativity impairment. Disease management should be personalized, and it should primarily depend on smoking cessation and physical activity. Phlebotomy and platelet aggregation inhibitors' prescriptions can be discussed. There is no contraindication to flights, high-altitude conditions, or pregnancy. Nevertheless, blood donation must be prohibited.

Opportunistic infections (OI) are uncommon in sarcoidosis (1 to 10%) and mostly occur in patients with previously diagnosed disease or can rarely be the presenting manifestation. The most common OIs are, in descending order: aspergillosis, cryptococcosis, and mycobacterial infections. Treatment with corticosteroids is the most frequent risk factor for OI occurrence during sarcoidosis but immunosuppressive drugs and therapy with anti-TNFα are also risk factors. Overall, clinical presentation, treatment, and outcome are identical to that occur in other conditions complicated with the occurrence of OIs. However, some atypical presentations of OIs can mimic sarcoidosis exacerbation and misdiagnosis may lead clinicians to increase immunosuppression, causing worsening of the OI. The meticulous collection of patient's history along with factors differentiating OI from sarcoidosis exacerbation is key factor to optimally manage these patients.

Spontaneous actin dynamics in contractile rings

NASA Astrophysics Data System (ADS)

Kruse, Karsten; Wollrab, Viktoria; Thiagarajan, Raghavan; Wald, Anne; Riveline, Daniel

Networks of polymerizing actin filaments are known to be capable to self-organize into a variety of structures. For example, spontaneous actin polymerization waves have been observed in living cells in a number of circumstances, notably, in crawling neutrophils and slime molds. During later stages of cell division, they can also spontaneously form a contractile ring that will eventually cleave the cell into two daughter cells. We present a framework for describing networks of polymerizing actin filaments, where assembly is regulated by various proteins. It can also include the effects of molecular motors. We show that the molecular processes driven by these proteins can generate various structures that have been observed in contractile rings of fission yeast and mammalian cells. We discuss a possible functional role of each of these patterns.

2017-10-01

IgA vasculitis is a systemic small vessel leukocytoclastic vasculitis characterized by skin purpura, arthritis, abdominal pain and nephritis. Most of the abdominal complications are due to edema and hemorrhage in the small bowel wall, but rarely to acute secondary pancreatitis. Here, we report a 53-year-old woman who presented with acute pancreatitis and, secondarily, developed skin purpura and arthritis at the seventh day of the clinical onset. Biological tests and computed tomographic scan allowed to rule out another cause of pancreatitis and IgA vasculitis was diagnosed as its etiology. The outcome was favorable without any relapse on glucocorticoids. Despite its rarity, pancreatitis is a potential life-threatening complication of IgA vasculitis in which the role of glucocorticoids and immunosuppressive drugs remains uncertain. A prompt elimination of other usual pancreatitis etiologies is mandatory to improve the management of the patients. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

In 2015, besides the fact that it still fills the gastroenterologists' offices and impairs patient's quality of life, the irritable bowel syndrome has considerably evolved on several points. The pathophysiology is now organized around a consensual hypothesis called the "brain-gut axis", which gather all the influences of peripheral factors as gut microbiota or local serotonin secretion, on the central pain perception, contributing to visceral hypersensitivity and transit modifications. About the diagnosis, the key message is "avoid over-prescription" of additional tests, and reminds that a positive clinical diagnosis based on Rome III criteria is possible after the elimination of simple clinical warning signs. Finally, the food component, a neglected and historical claim of patients, finally finds a strong scientific rational, with a diet low in fermentable sugar and polyols, that gives positive and reproducible results.

Rapid desensitization allows secure administration of a drug and is indicated when there is no therapeutic alternative. We report a 49-year-old patient who presented with a hypersensitivity reaction following an infusion of rituximab (375mg/m(2)) in the context of a Castleman's syndrome. After a clinical flare (splenomegaly, adenopathies) despite treatment with tocilizumab, anakinra and valganciclovir, the reintroduction of rituximab was decided, according to the rapid desensitization protocol. Four full dose desensitizations were successfully performed allowing immediate clinical improvement (apyrexia, loss of sweating and lymphadenopathy, splenomegaly partial regression) and biological (negativation of HHV8 viral load, and disappearance of neutropenia, anemia and thrombocytopenia). Rapid desensitization is a promising method for the pursuit of rituximab therapy after a hypersensitivity reaction and should be considered in patients with no acceptable therapeutic alternative.

2018-02-01

The most common causes of high anion gap metabolic acidosis (HAGMA) are lactic acidosis, ketoacidosis, and intoxications. Nevertheless, clinicians can be faced with unexplained HAGMA, with a need to look for less common etiologies. We describe a case of 5-oxoproline (pyroglutamate) acidosis due to chronic acetaminophen ingestion at therapeutic dose in a 79-year-old inpatient. The pathophysiology of this condition is detailed, with abnormalities in the gamma-glutamyl cycle due to acetaminophen ingestion and severe chronic morbidities, resulting in glutathione and cysteine deficiency and then accumulation of 5-oxoproline. In HAGMA, when usual causes have been excluded, 5-oxoproline acidosis should be suspected in patients with chronic morbidities and acetaminophen ingestion. This diagnosis should be kept in mind because it generally resolves quickly with cessation of acetaminophen and administration of intravenous fluids.

Posterior reversible encephalopathy syndrome is a clinico-radiological entity characterized by neurologic symptoms in association with usually reversible bilateral posterior hemispheric oedema on neuroimaging. Many pathological conditions and treatments have been associated with this syndrome. We report a 19-year-old woman, followed-up for hypocomplementemic urticarial vasculitis, who presented with a posterior reversible encephalopathy syndrome induced by the intake of an over-the-counter cold remedy containing pseudoephedrine. Clinical manifestations and radiological abnormalities resolved after anti-hypertensive therapy and withdrawal of sympathomimetic drug. The diagnosis of posterior reversible encephalopathy syndrome should be considered in patients with compatible clinical and radiological presentation because of its potential reversibility with an appropriate management. Intake of drugs, including over-the-counter cough and cold drugs, should be looked for in the history as well as autoimmune disorders.

In May 2014, the European Union Parliament and Council published a new regulation on clinical trials on medicinal products for human use, which is designed to replace Directive 2001/20/EC. It will not come into effect until 2016. Nevertheless, it is essential to examine its relationship with national legislation, i.e. the Jardé Act, whose implementation has been delayed pending publication of the European regulation. The Giens workshop identified and examined the various issues that this relationship is bound to raise. In particular, it looked at trial methodology assessment procedures, the working relationship between the French National Agency of Drug Safety and Health Products (Agence Nationale de Sécurité du Médicament et des Produits de Santé, ANSM) and ethics committees during the authorization application evaluation phase, review of post-authorization/registration studies on medicinal products and medical devices, and data transparency. © 2015 Société Française de Pharmacologie et de Thérapeutique.

2013-12-01

Nervous system involvement occurs in 5 to 15% of the patients with sarcoidosis. Neurosarcoidosis remains very difficult to diagnose because clinical presentation and imaging characteristics lack specificity. We report a 26-year-old man who gradually developed headaches, memory disturbance and epilepsy. CT-scan and MRI showed a temporal-parietal cystic mass, secondary to a rare and focal form of hydrocephalus, called "trapped temporal horn" revealing neurosarcoidosis. The "entrapped temporal horn" is due to an obstacle on the cerebrospinal fluid pathway at the trigone of the lateral ventricle that seals off the temporal horn and the choroid plexus from the rest of the ventricular system. The obstacle is related to the granulomatous tissue of sarcoidosis. Therefore, the "trapped temporal horn" acts as a space occupying process, causing headaches, memory pain, hemiparesis, homonymous hemianopsia, and requires medico-surgical management.

Retinal vasculitis (RV) is an inflammation of retinal blood vessels that can be associated with uveitis or be isolated, and can induce vascular occlusion and retinal ischemia. Visual acuity can be severely affected in case of macular involvement or neovessel formation. The diagnosis relies on fundoscopy and fluorescein angiography. Systemic diseases may be associated with RV, the most frequently encountered are Behçet's disease, sarcoidosis or multiple sclerosis, all predominantly associated with venous involvement, whereas systemic lupus erythematosus and necrotizing vasculitis are less frequently observed and predominantly associated with arterial or mixed vasculitis. Treatments are usually aggressive in order to preserve a good visual acuity and to reduce retinal inflammation and chronic ischemia. Steroids, immunosuppressive drugs, retinal laser photocoagulation, intravitreal anti-VEGF injections are usual treatments and more recently, anti-TNFalpha monoclonal therapeutic antibodies have been shown to be very successful.

Brousselle, Astrid; Champagne, François

2012-01-01

In 1997, UNAIDS decided to implement Drug Access Initiatives (DAI) in four different pilot-countries. We studied the implementation of the DAI in Chile as part of the evaluation program conducted by the ‘Agence Nationale de Recherche sur le SIDA’ (ANRS/France). The objective was to understand how the politico-organizational dynamic influenced the implementation process of the DAI. Approximately 50 semi-directed interviews and observation activities were conducted with the actors who participated in the implementation of the DAI or who played a role in the HIV/AIDS context. The program theory models were established and their evolution analyzed. This article offers an original analysis of an international HIV/AIDS drug access program that was put in place at a time when such programs were seen as a priority by international and governmental institutions. It also offers some insights for the creation of international projects that will be locally implemented. PMID:23230344

This paper reports that the French government has decided to slash its direct stake in partly state owned oil company Total to 5% from 31.7%, a surprise move expected to raise 10 billion francs ($1.8 billion). At the same time, other state owned entities will be asked to boost their combined 2.2% stake in Total to 10%, leaving the government with a net 15% interest in Total vs. the current 34%. Initially, state owned insurance companies Groupe des Assurances Nationales and Assurances Generale de France will be asked to hike their stakes in Total, but others could be asked tomore » join if needed to meet the 10% target. The government the its phase-down of participation in Total, established in 1924 to manage French interests in Iraq Petroleum Co., was prompted by the evolution of the oil context, which differs greatly from what had prompted a significant stake of the state in Total's capital.« less

Multidrug-resistant bacteria are a major worldwide health public concern. It results from the growing increase in antibiotic prescriptions, which are responsible for selection pressure on bacteria. In France like in other countries, enterobacteriaceae producing extended spectrum beta-lactamase (EESBL) are the predominant multidrug-resistant bacteria. EESBL may be responsible for severe infections and require prescription of broad-spectrum antibacterial agents. The current EESBL outbreak is different from methicillin-resistant Staphylococcus aureus outbreak that occurred in the early 1980. Consistently, EESBL are isolated both in hospital and community. Moreover, standard hygiene measures appear ineffective since EESBL prevalence is still increasing. The current inability to contain EESBL outbreak is due to several factors, including the existence of a wide community- and hospital-acquired tank of EESBL, failure to follow strict rules for hygiene, and the current irrational prescription of antibiotics.

2013-01-01

The prevalence of vertebral sarcoidosis is highly variable (1 to 36% of reported case series). Because of limited clinical expression, its frequency is probably underestimated. Its proper management is not clearly defined. A 42-year-old woman who had a past medical history of cutaneous and pulmonary sarcoidosis presented with low back pain that was refractory to usual medical treatment. A diagnosis of vertebral localisation of sarcoidosis was considered on the history of proven sarcoidosis, radiological features, and the absence of evidence of an alternative diagnosis. In the absence of other clinical or biological evidence of active sarcoidosis, a simple follow-up was planned. MRI control at 1 year showed the resolution of vertebral sarcoidosis lesions. Spontaneous regression is a possible outcome of vertebral sarcoidosis. Initiation of a specific treatment should be discussed in the absence of other visceral involvement.

Totally implantable venous access port plays a crucial role in the treatment of patients in oncology. However, its use can result sporadically in catheter fracture with catheter tip embolization into pulmonary arteries. We report this unusual but potentially serious complication in four patients. In these patients, the port had been inserted percutaneously into the subclavian vein using the infra-clavicular approach. This side effect occurred late in three patients. In all patients, the catheter fracture was asymptomatic or pauci-symptomatic and was caused by the pinch-off syndrome. The retrieval of the embolized fragments was successfully performed by transcatheter procedure in the cardiac catheterisation laboratory. We reviewed the literature and the newest guidelines and recommendations to detail the clinico-radiological features, the possible causes of this complication and discussed means to recognize, manage and prevent it.

The aim of this work is to assess, on an historical and critical point of view, the new psychological perspective, introduced by Charcot (1825-1893), during the ten last years (1882-1892) of his life to explain hysteria symptomas. From clinical examples (hypnosis and hypnotherapy, "hystero-traumatism", "psychological theory of hysteria", "faith healing"), the paper shows how psychological dimension went back into the Parisian Hospital Medicine. This occurred on the late XIXth century, just one century after Mesmer, when Freud was Charcot's intern, at La Salpêtrière hospital, during years 1885-1886. The return of a non-rational thought into hospital medicine upset the organicist concepts of the Parisian "Ecole anatomo-clinique".

Between 1898 and 1900, France sent a mission to Indochina conducted by Jeanselme in order to inquire about the possible actions to protect people from infectious diseases especially plague. In the conclusions of the final report appeared the necessity to create a medical school for and with local people. Paul Doumer, governor general of Indochina, received the order from the French government to found at Hanoi such a structure with an hospital including managing staff purposing to cure all kinds of pathology principally tropical diseases. Yersin, Pasteur's disciple, was asked as its director. Several civil and military physicians formed with him a very efficient teaching group and first courses began in 1902 with thirteen french-speaking students. At the end of this year successful results were obtained. This medical school structured as a french pattern of a medical teaching hospital obtained a full legal status after many years. Galliard and Huard played a major role in its development by their rare qualities of mind. Scientific works were impressive in parasitology, anatomy and surgery. Ton-That Tung (1912-1982) was the most famous among Huard's several students. He became a great surgeon of his time, specialized in hepatology. The medical school of Hanoi illustrated a model of a well balanced development between traditional medicine strictly preserved and the resource of european medicine. It also constituted an exceptional example of possible cooperation between two peoples so different in culture.

Ionic liquids (ILs) are efficient solvents for the selective removal of CO2 from flue gas. Conventional, offthe-shelf ILs are limited in use to physisorption, which restricts their absorption capacity. After adding a chemical functionality like amines or alcohols, absorption of CO2 occurs mainly by chemisorption. This greatly enhances CO2 absorption and makes ILs suitable for potential industrial applications. By carefully choosing the anion and the cation of the IL, equimolar absorption of CO2 is possible. This paper reviews the current state of the art of CO2 capture by ILs and presents the current research in this field performed at the ChemTech Institute of the Ecole d'Ingénieurs et d'Architectes de Fribourg.

While the genetic basis to plate morph evolution of the three-spined stickleback (Gasterosteus aculeatus) is well described, the environmental variables that select for different plate and spine morphs are incompletely understood. Using replicate populations of three-spined sticklebacks on North Uist, Scotland, we previously investigated the role of predation pressure and calcium limitation on the adaptive evolution of stickleback morphology and behavior. While dissolved calcium proved a significant predictor of plate and spine morph, predator abundance did not. Ecol. Evol., xxx, 2014 and xxx performed a comparable analysis to our own to address the same question. They failed to detect a significant effect of dissolved calcium on morphological evolution, but did establish a significant effect of predation; albeit in the opposite direction to their prediction.

Sterken, C.; Dick, W. R.; Hamel, J.

2002-12-01

The 14th volume of the Acta Historica Astronomiae is the Proceedings of a Colloquium International Relationships in Astronomy (in German) organised by the History of Astronomy Section of the Astronomische Gesellschaft held on September 18 in Lilienthal, Germany. The book contains 13 articles on astronomical topics covering the 19th and 20th centuries. The first paper is by Guenther Oestmann and deals with contemporary assessments of Johann Hieronymus Schroeter's (1745-1816) astronomical works and with later judgements of the scientific importance and significance of his observations as seen by astronomers and historians. This report is complemented by a second article on Schroeter's 25-ft reflector in Lilienthal near Bremen. To this end, author Felix Luehning has constructed a scale model of the telescope, and shows how the building of a model brings a deeper understanding of function and handling of this instrument. This brings us to a third paper on telescope building in Lilienthal: Hans-Joachim Leue describes the cooperation of Johann Hieronymus Schroeter and Johann Gottlieb Schrader in developing a white reflecting metal alloy for use as telescope mirror. The fourth article, by Klaus Schillinger, describes on the basis of archival documents the aquisition history of the Herschel telescopes, including telescope quality check, repair and building. Memorial sites referring to Wilhelm Olbers, Johann Hieronymus Schroeter, Friedrich Wilhelm Bessel and Carl Friedrich Gauss are described by Arno Langkavel in two walks outlined in the very last paper of this book. Peter Brosche, in the fifth paper, discusses the rediscovery of Ceres in December1801, a discovery that was the result of the combined efforts of a theoretician (Gauss) and an observer (Zach). Juergen Hamel's paper is based on previously unused archival sources and discusses the outstanding role played by H. C. Schumacher (1780-1850, editor of the Astronomische Nachrichten) in the communication between astronomers in his days, when his working place at Altona still belonged to the kingdom of Denmark. This paper is followed by a second one by the same author and deals with the correspondence of H. C. Schumacher and H C. Oersted (1777-1851) and shows how intense and diverse their cooperation was. In a subsequent paper, Wolfgang Kokott describes the role of the Astronomisches Jahrbuch (published from 1776 by the Royal Academy of Sciences at Berlin), a ranking international publication, with Bode's modest Berlin Observatory serving as a clearinghouse of information originating from virtually all European countries. "Karl Schwarzschild and the professionalisation of Astrophysics" is the title of Theodor Schmidt-Kaler's contribution and presents Schwarzschild's contributions to professionalization of astronomy: establishment of course lectures and a permanent astrophysical laboratory, a tight connection between teaching and research, stimulations and suggestions for astronomy at high school and for the formation of high school teachers, international organisation, and the planning of a southern observatory. Peter Habison describes the contribution of Leo de Ball (1853-1916, Director of the Kuffner Observatory in Vienna) to international astronomy. Internationalization in astronomy is also discussed in a following paper by Gudrun Wolfschmidt on the establishment of the Vereinigte Astronomische Gesellschaft, the international Astronomische Gesellschaft in 1863 and finally the International Astronomical Union in 1919. In the second but last paper of the book, Hilmar Duerbeck describes the history of the Chilean National Observatory, beginning with its origins out of Gilliss' US Naval Expedition to the Southern Hemisphere in 1849, over its directors Moesta, Vergara, Obrecht and Ristenpart, to the middle of the 20th century. The paper also includes the astronomical development at the Universidad Catolica and various international expeditions, which aimed at the observations of solar eclipses, the Venus transit of 1882, and the Mars opposition of 1907. An overview of the evolution and the actual state of the international observatories Cerro Tololo, La Silla and Paranal, as well as Las Campanas is also given.

Local responses to French medical imperialism in late nineteenth-century Algeria.

PubMed

Gallois, William

2007-08-01

This article offers the first account of the lives of Algerian-born doctors working in the French colonial medical service between 1870 and 1900. Their stories reveal the manner in which the idea of medical imperialism had collapsed in Algeria, as a result of maladministration, racial policies, competition between civil and military authorities, budgetary constraints and the rise of the colons. The article also indicates the way in which medicine became a locus of opposition to French rule. It shows how the first decades of the Third Republic were critical in terms of a shift from the earlier idea of medicine serving as an emblem of the mission civilisatrice to the ideological potential of medicine being seen in much more nuanced terms by both French settlers and Algerian locals. It is argued that the notion of cultural resistance to imperialism through medicine emerges in the 1870s and 1880s, thereby prefiguring the work of Fanon and the Front de Liberation Nationale's later analysis of the 'sickness' of colonial Algerian society.

A model for evaluating radiological impacts on organisms other than man for use in post-closure assessments of geological repositories for radioactive wastes.

Bioaccumulation and dosimetric models have been developed that allow the computation of dose rates to a wide variety of plants and animals in the context of the deep geological disposal of solid radioactive wastes. These dose rates can be compared with the threshold dose rates at which significant deleterious effects have been observed in field and laboratory observations. This provides a general indication of whether effects on ecosystems could be observable, but does not quantify the level of those effects. To address this latter issue, two indicator organisms were identified and exposure-response relationships were developed for endpoints of potential interest (mortality in conifers and the induction of skeletal malformations in rodents irradiated in utero). The bioaccumulation, dosimetry and exposure-response models were implemented and used to evaluate the potential significance of radionuclide releases from a proposed deep geological repository for radioactive wastes in France. This evaluation was undertaken in the context of a programme of assessment studies being performed by the Agence nationale pour la gestion des déchets radioactifs (ANDRA).

The classification of syphilis distinguishes early syphilis where patients are contagious (primary, secondary and early latent of less than one year) and late syphilis where patients are not (or less) contagious (late latent of more than one year and tertiary). The clinical presentation of syphilis has not changed. However, we must insist on the early forms of neurosyphilis, notably ophthalmic syphilis often under-diagnosed, as it affects the treatment. Serologic tests may be improved but are very helpful for the positive diagnosis and the follow-up after treatment. Treatment of early syphilis is based on one injection of benzathine benzyl penicillin G. Patients who have had syphilis must be regularly followed-up after treatment, as re-infections are common and are often asymptomatic.

The extraction of information from social media is an essential yet complicated step for data analysis in multiple domains. In this paper, we present Vigi4Med Scraper, a generic open source framework for extracting structured data from web forums. Our framework is highly configurable; using a configuration file, the user can freely choose the data to extract from any web forum. The extracted data are anonymized and represented in a semantic structure using Resource Description Framework (RDF) graphs. This representation enables efficient manipulation by data analysis algorithms and allows the collected data to be directly linked to any existing semantic resource. To avoid server overload, an integrated proxy with caching functionality imposes a minimal delay between sequential requests. Vigi4Med Scraper represents the first step of Vigi4Med, a project to detect adverse drug reactions (ADRs) from social networks founded by the French drug safety agency Agence Nationale de Sécurité du Médicament (ANSM). Vigi4Med Scraper has successfully extracted greater than 200 gigabytes of data from the web forums of over 20 different websites. PMID:28122056

[Enzymes for disrupting bacterial communication, an alternative to antibiotics?

PubMed

Rémy, B; Plener, L; Elias, M; Daudé, D; Chabrière, E

2016-11-01

Quorum sensing (QS) is used by bacteria to communicate and synchronize their actions according to the cell density. In this way, they produce and secrete in the surrounding environment small molecules dubbed autoinducers (AIs) that regulate the expression of certain genes. The phenotypic traits regulated by QS are diverse and include pathogenicity, biofilm formation or resistance to anti-microbial treatments. The strategy, aiming at disrupting QS, known as quorum quenching (QQ), has emerged to counteract bacterial virulence and involves QS-inhibitors (QSI) or QQ-enzymes degrading AIs. Differently from antibiotics, QQ aims at blocking cell signaling and does not alter bacterial survival. This considerably decreases the selection pressure as compared to bactericide treatments and may reduce the occurrence of resistance mechanisms. QQ-enzymes are particularly appealing as they may disrupt molecular QS-signal without entering the cell and in a catalytic way. This review covers several aspects of QQ-based medical applications and the potential subsequent emergence of resistance is discussed. Copyright © 2016 Académie Nationale de Pharmacie.

Pulmonary intravascular talcosis is a rare condition occurring in intravenous drug users injecting oral medications. Talc results in a foreign-body granulomatous reaction giving a radiological haematogenic miliary appearance mimicking miliary tuberculosis. Drug users represent a population at risk for both these conditions and their distinction may be challenging. We reported the case of a man, 33 year-old, intravenous drug addict, detected by the health services because he was the partner of a person who died of contagious and multi-resistant tuberculosis. Chest X-ray and CT scan showed a typical miliary appearance. Despite negative microbiology, clinical diagnosis of miliary tuberculosis was retained. Due to the lack of radiological improvement despite appropriate antibiotic treatment, re-evaluation and trans-bronchial biopsy were undertaken. The presence of granulomas centered by birefringent foreign bodies in polarized light led to a diagnosis of pulmonary intravascular talcosis. In the presence of pulmonary miliary in an intravenous drug addict, intravascular talcosis should be suspected. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

2014-02-01

Behçet's disease (BD) is a systemic large-vessel vasculitis characterized by a wide clinical spectrum including recurrent oral and genital ulcerations, uveitis, vascular, neurological, articular, and gastrointestinal manifestations. Therapeutic management of BD depends on the clinical presentation and organ involved. Although colchicine, non-steroidal anti-inflammatory agents and topical treatments with corticosteroids are often sufficient for mucocutaneous and joint involvement, a more aggressive approach with immunosuppressive agents is warranted for severe manifestations such as posterior uveitis, retinal vasculitis, vascular, neurological and gastrointestinal involvement. However, some patients still have refractory disease, relapses, sight threatening eye disease, or irreversible organ damage. Recent improvements in the understanding of the pathogenic mechanisms have led to the identification of potential targets and future therapies for BD. In contrast to current non-specific immunosuppressive agents, the emergence of immunomodulatory drugs provides the possibility of interfering with specific pathogenic pathways. Novel targeted immunosuppressive therapies might be used in the future for BD. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18 FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

Lymphogranuloma venereum (LG) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis L serovar. These five consecutive cases aim to highlight the risk of LG misdiagnosis, in case of initial presentation with isolated inguinal adenitis. Five men (mean age: 30±7 years) were seen in an internal medicine department, for inguinal adenopathy. One patient had clinical signs of urethritis. None presented an associated rectitis. Three patients had a history of STI, and two had a discovery of related HIV disease. Urinary polymerase chain reaction (PCR) was positive for the symptomatic patient and negative for the others. Lymph node PCR was positive in all patients within a L2b serotype (searched in 4 out of 5 cases). LG should be evoked in any patient with inguinal adenomegaly, particularly in case of STI history or risk factors. Negativity of urinary PCR should lead to further investigations, essentially a lymph node cytopuncture to evidence C. trachomatis.

Langerhans cell histiocytosis (LCH) is a rare disease characterized by the infiltration of one or more organs by Langerhans cell-like dendritic cells, most often organized in granulomas. The disease has been initially described in children. The clinical picture of LCH is highly variable. Bone, skin, pituitary gland, lung, central nervous system, lymphoid organs are the main organs involved whereas liver and intestinal tract localizations are less frequently encountered. LCH course ranges from a fulminant multisystem disease to spontaneous resolution. Several randomized controlled trials have enable pediatricians to refine the management of children with LCH. Adult LCH has some specific features and poses distinct therapeutic challenges, knowing that data on these patients are limited. Herein, we will provide an overview of current knowledge regarding adult LCH and its management. We will also discuss recent advances in the understanding of the disease, (i.e. the role of BRAF oncogene) that opens the way toward targeted therapies.

The increasing bacterial resistance to antibiotics has become a major public health concern bringing the threat of therapeutic impasses. In this context, control of the spread of highly-resistant bacteria emerging antibiotics (BHRe), such as glycopeptide-resistant enterococci (VRE) and Enterobacteriaceae producing carbapenemases (CPE), is based on a dual strategy of reducing the prescription of antibiotics to limit the pressure selection and preventing the spread from carriers. Prevention strategy is based on three different levels such as standard precautions for all patients with a particular focus on the management of excreta, and additional precautions for BHRe carriers. What makes it difficult is that carriage is usually completely asymptomatic, enterobacteria and enterococci are normal commensal of gut microbiota. Explosive dissemination of Enterobacteriaceae producing extended spectrum beta-lactamases in hospital and community heralds the emergence of CPE whose import by patients with a history of hospitalization in abroad may be the main source of spread in France.

The favorable season for Aedes albopictus circulation has started in Europe and may lead to autochthonous transmission of Zika virus. Health care providers should be familiar with evocative clinical presentations and able to give updated information to women of reproductive age infected by Zika virus. We report five laboratory-confirmed Zika virus infections imported to metropolitan France from Central and South America between January and April, 2016. The five young women were not connected and not pregnant; common presentation combined a rash with persistent arthralgia. Zika virus was identified by RT-PCR from serum or urines, between two and eight days after the onset of the symptoms. As the duration of potential materno-foetal infectivity is still unknown, we were unable to answer with certitude to the patients' questions about the time interval to respect before attempting a pregnancy: one of them became pregnant one month after the diagnosis.

2012-01-01

One out of four ischemic strokes in France occurs in adults under 65 years old. About a third of them remain unexplained even after an extensive etiological assessment. A large part of these unexplained strokes could be linked to illegal drug abuse, and 10 % are estimated to be directly linked to illegal drugs in some international studies. The most frequently incriminated recreational drug remains cocaine, via several mechanisms. However, several other illegal drugs, some very commonly used such as cannabis, are suspected to have an important role in neurovascular diseases. In this article, we reviewed the epidemiological, pathophysiological and clinical studies, published in the international literature over the past 30 years. The drug-caused stroke epidemiology needs to be more precisely studied, as well as the underlying mechanisms depending on each drug. This is a public health issue that affects an economically active population, as stroke is the first cause of acquired handicap in adults.

The role of biomarkers in clinical research was recently highlighted in the new criteria for the diagnosis of Alzheimer's disease. Cerebro-spinal fluid (CSF) biomarkers (total Tau protein, threonine 181 phosphorylated Tau protein and amyloid Aβ1-42 peptide) are associated with cerebral neuropathological lesions observed in Alzheimer's disease (neuronal death, neurofibrillary tangle with abnormal Tau deposits and amyloid plaque). Aβ1-40 amyloid peptide dosage helps to interpret Aβ1-42 results. As suggested in the latest international criteria and the French HAS (Haute Autorité de santé) recommendations, using theses CSF biomarkers should not be systematic but sometimes could be performed to improve confidence about the diagnostic of Alzheimer's disease in young subjects or in complex clinical situations. Future biomarkers actually in development will additionally help in diagnostic process (differential diagnosis) and in prognostic evaluation of neurodegenerative diseases.

Thrombotic microangiopathies (TMA) represent rare diseases requiring a high skill for their management that deserved in France the identification of a dedicated National reference center. TMA are short-term life-threatening diseases; however, with an adapted management, their prognosis can be excellent. It is therefore mandatory to recognize and treat them rapidly according to standard guidelines. Telemedicine is a specialized hub consisting of highly skilled staff trained in a specific domain of medicine. The telemedicine activity of a reference center is an important representative indicator of its expertise and recourse ability. It requires to be accurately evaluated and promoted. In this work, we report the French reference center for TMA telemedicine activity since its setting-up. TMA represent an interesting model of diseases that required a specific organization of telemedicine activity to adapt to clinicians demand, which includes particularly the need to answer resorts in real time 24/7.

Security and quality of the Medicinal Therapy are one of the most important objectives of the April 6th, 2011 order. The objective is to realize this study of the risks incurred by patients related to management and security of medicinal therapy in order to establish a plan to reduce the risks of drug's dispensation. The method of the Preliminary Risk Analysis (PRA) has been implemented by a multidisciplinary group in a hospital service of orthopaedic surgery. The study focused on the dispensation phase of medicinal circuit. This analysis revealed 148 scenarii, 35 were criticality unacceptable. Fifty-four initial risk control actions were proposed and their stress levels to put them in place were evaluated. The main measures of risk management are: training, information, communication, computerization, automation, dual control, updating the documentation system, drug reconciliation and respect for Best Practices Hospitallers (BPH). Risk management requires a significant human and financial investment as well as, material resources and multidisciplinary expertise in order to offer the best solutions.

Jean Francheteau, pioneering marine geologist and geophysicist, AGU Fellow, and emeritus professor at the University of Brest (Université de Bretagne Occidentale), died on 21 July in St-Renan, Brittany, France, at the age of 67 after a long illness. With his passing, the field of Earth sciences lost a major contributor to the development of a definitive theory of plate tectonics and one of the first to make visual geological observations on the deep seafloor. Such scientific accomplishments, coupled with his personal charm and the ability to collaborate with researchers from many institutions, ensured that he had a huge influence not only on the world of research but also on teaching and the application of ethics to science. Jean arrived at Scripps Institution of Oceanography in La Jolla, Calif., in 1966 after obtaining a diploma in mining engineering at the prestigious Éole Nationale Supérieure de la Métallurgie et de l'Industrie des Mines in Nancy, France. He chose Victor Vacquier as his thesis supervisor and began working in Vic's lab with John Sclater, ostensibly on heat flow measurements.

We propose in this work an efficient way to evaluate the measurement of uncertainty at the end of the development step of an analytical method, since this assessment provides an indication of the performance of the optimization process. The estimation of the uncertainty is done through a robustness test by applying a Placquett-Burman design, investigating six parameters influencing the simultaneous chromatographic assay of five water-soluble vitamins. The estimated effects of the variation of each parameter are translated into standard uncertainty value at each concentration level. The values obtained of the relative uncertainty do not exceed the acceptance limit of 5%, showing that the procedure development was well done. In addition, a statistical comparison conducted to compare standard uncertainty after the development stage and those of the validation step indicates that the estimated uncertainty are equivalent. The results obtained show clearly the performance and capacity of the chromatographic method to simultaneously assay the five vitamins and suitability for use in routine application.

Laminopathies (diseases related to A/C mutations of lamines) are rare genetic diseases with an extensive phenotypic spectrum, including lipodystrophic syndromes-characterized by a selective loss of adipose tissue-of which the partial Dunnigan family type is the most frequent. We report on a 55-year-old woman with diabetes and long-term disabling myalgia. Her cushingoid morphotype, associated with cutaneous lipo-atrophy and muscle hypertrophy in addition to a genetic heritage, led us to the diagnosis of complex partial familial lipodystrophy heterozygous LMNA_c.82C>T, p.Arg28Trp mutation. Familial partial lipodystrophic syndromes may have varied phenotypes, mainly cardio-metabolic, which could mimic a particularly severe type 2 diabetes. The diagnostic work-up of this disease has to include a careful investigation of gait troubles and paroxysmal conduction that could lead to sudden death, as well as a genetic examination. In some cases, recombinant leptin can be proposed. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

The Mars Desert Research Station (MDRS) is situated in an analogue habitat-based Martian environment, designed for missions to determine the knowledge and equipment necessary for successful future planetary exploration. For this purpose, a crew of six people worked and lived together in a closed-system environment. They performed habitability experiments within the dwelling and conducted Extra-Vehicular Activities (EVAs) for two weeks (20 Feb to 6 Mar 2010) and were guided externally by mission support, called "Earth" within the simulation. Crew 91, an international, mixed-gender, and multidisciplinary group, has completed several studies during the first mission of the EuroMoonMars campaign. The crew is composed of an Italian designer and human factors specialist, a Dutch geologist, an American physicist, and three French aerospace engineering students from Ecole de l'Air, all with ages between 21 and 31. Each crewmember worked on personal research and fulfilled a unique role within the group: commander, executive officer, engineer, health and safety officer, scientist, and journalist. The expedition focused on human factors, performance, communication, health and safety pro-tocols, and EVA procedures. The engineers' projects aimed to improve rover manoeuvrability, far-field communication, and data exchanges between the base and the rover or astronaut. The crew physicist evaluated dust control methods inside and outside the habitat. The geologist tested planetary geological sampling procedures. The crew designer investigated performance and overall habitability in the context of the Mars Habitability Experiment from the Extreme-Design group. During the mission the crew also participated in the Food Study and in the Ethospace study, managed by external groups. The poster will present crew dynamics, scientific results and daily schedule from a Human Factors perspective.

The territory size distribution of the termites Nasutitermes nigriceps and Nasutitermes corniger (Isoptera: Termitidae) in a mangrove forest on the Atlantic coast of Panama showed a rapidly decline region in the rear part and was strongly affected by the degree of connection between the prop roots of mangrove trees [Adams, E.S., Levings, S., 1987. Territory size and population limits in mangrove termites. J. Anim. Ecol. 56, 1069-1081]. To account for these empirical facts, we introduced a lattice model to simulate territorial competition under seasonal cycle, dry and wet season. The simulated territory grew during the wet season while it shrunk during the dry season. The model simulation showed that the shrinkage and expansion process resulted in winner and loser territories in the territorial competition, which consequently led to generate the declining regions.

[Therapy and suggestion].

Barrucand, D; Paille, F

Therapy and suggestion are closely related. That is clear for the ancient time: primitive medicine gives a good place to the Word. In plant, animal or mineral remedies, the suggestion is clearly preponderant. Towards the end of the 19th century, the "Ecole de Nancy" sets up a real theory of the suggestion, and Bernheim, its leader, bases hypnosis, then psychotherapy on this concept. Thereafter Coué will bring up the "conscious autosuggestion". Today, despite the progress of scientific medicine, the part of suggestion is still very important in medical therapy (with or without drugs), or in chirurgical therapy; this part is also very important in psychotherapies, whatever has been said in this field. This has to be known and used consciously in the doctor-patient relation, which is always essential in the therapeutic effectiveness.

While the genetic basis to plate morph evolution of the three-spined stickleback (Gasterosteus aculeatus) is well described, the environmental variables that select for different plate and spine morphs are incompletely understood. Using replicate populations of three-spined sticklebacks on North Uist, Scotland, we previously investigated the role of predation pressure and calcium limitation on the adaptive evolution of stickleback morphology and behavior. While dissolved calcium proved a significant predictor of plate and spine morph, predator abundance did not. Ecol. Evol., xxx, 2014 and xxx performed a comparable analysis to our own to address the same question. They failed to detect a significant effect of dissolved calcium on morphological evolution, but did establish a significant effect of predation; albeit in the opposite direction to their prediction.

In October 2004, the 77 interns appointed to surgery in Paris on the basis of the ENC participated in a one-day urology initiation session organized by the AFUF, at the AP-HP School of Surgery. All interns were given a questionnaire at the beginning of the session to record the following data: age, gender, teaching hospital, a student attachment in urology and desired specialization as a function of the surgical training programmes proposed by the ENC. Items concerning the desired specialization were resubmitted to the interns at the end of the session. Population. 77 interns, 48 females (62.3%) and 29 males (37.7%) with a mean age of 25.2 +/- 5 years (range: 23-31). 55 interns had trained at a Parisian teaching hospital (67%) and 22 (28.6%) had trained at a provincial teaching hospital. 16 interns (20.8%) had completed at least one urology attachment during their medical training. Desired specialization. Orthopaedics was the discipline most frequently cited (n = 20; 26%). Urology was chosen by 8 interns (10.40%), who had all completed an urology attachment during their medical training. At the end of the urology initiation session, another 8 interns expressed the desire to specialize in urology. Of the 16 potential urology interns, 9 (56.2%) confirmed that their decision was final. Urology occupies a special place and remains a popular surgical speciality among students. Organization of practical sessions constitutes a solution to inform, create an emulation and motivate surgery interns to choose urology.

In peatlands, median values of CH4-C were 85.2, 23.7, 0.07 and 0.12 kg ha-1 yr-1, and N2O-N -0.05, -0.01, 0.18 and 0.19 kg ha-1 yr-1, respectively. There were significantly higher emissions of N2O from abandoned and active peat mining areas, whereas CH4 emissions were significantly higher in natural and drained areas. We also found that the buffering capacity of long-term loaded riparian alder forests in agricultural landscapes will decrease over time, which calls for the careful management of these riparian forests.

Complementary RNA sequencing was done and current transcriptomic analyses will show the regulation of calcium-downstream gene expression and of auxin dependent pathways at two short time steps following gravistimulus. In addition, some of the lentil roots grown in microgravity aboard the ISS were submitted for several hours to low level of gravity (10-2 g) close to the detection threshold determined on a previous experiment (GRAVI-1; Driss-Ecole et al., 2008). Root gravitropism in response to such a low level of gravity was investigated and compared to the very low statoliths displacement expected. This study give insights about the molecular mechanisms underlying the very high sensitivity of roots to gravity and are among the firsts studies involving global transcriptomic analyses of root material grown in microgravity.

Ensemble Classifiers for Predicting HIV-1 Resistance from Three Rule-Based Genotypic Resistance Interpretation Systems.

PubMed

Raposo, Letícia M; Nobre, Flavio F

2017-08-30

Resistance to antiretrovirals (ARVs) is a major problem faced by HIV-infected individuals. Different rule-based algorithms were developed to infer HIV-1 susceptibility to antiretrovirals from genotypic data. However, there is discordance between them, resulting in difficulties for clinical decisions about which treatment to use. Here, we developed ensemble classifiers integrating three interpretation algorithms: Agence Nationale de Recherche sur le SIDA (ANRS), Rega, and the genotypic resistance interpretation system from Stanford HIV Drug Resistance Database (HIVdb). Three approaches were applied to develop a classifier with a single resistance profile: stacked generalization, a simple plurality vote scheme and the selection of the interpretation system with the best performance. The strategies were compared with the Friedman's test and the performance of the classifiers was evaluated using the F-measure, sensitivity and specificity values. We found that the three strategies had similar performances for the selected antiretrovirals. For some cases, the stacking technique with naïve Bayes as the learning algorithm showed a statistically superior F-measure. This study demonstrates that ensemble classifiers can be an alternative tool for clinical decision-making since they provide a single resistance profile from the most commonly used resistance interpretation systems.

Ocular tuberculosis is a rare form of extra pulmonary tuberculosis. It represents 1-2% of all clinical forms. The aim of this work was to focus on diagnostic and therapeutic characteristics of ocular tuberculosis. We report a case series of 14 patients with ocular tuberculosis seen in an infectious diseases department between 2006 and 2015. The diagnosis was retained on clinical data and a positive tuberculin skin test or interferon-gamma release assay. The patient's mean age was 40.7±9years. The most common clinical presentation was uveitis (11 patients and 16 eyes). An extra ocular involvement was associated in three patients. The mean duration of antitubercular therapy was 10±2.5 months. Corticosteroid therapy was associated in 11 cases. The outcome was favorable in all cases. Two patients had maintained visual sequelae. Ocular tuberculosis is a rare disease but still remains a diagnostic problem. It should be considered in case of any chronic ocular symptoms, especially in endemic countries. Early management can improve the visual prognosis. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Pillebout, E; Verine, J

2014-06-01

Henoch-Schönlein purpura is a systemic vasculitis of the small vessels characterized by perivascular leucocyte infiltrates. It is an immunoglobulin A-related immune complex-mediated disease involving the skin, the joints and the gastrointestinal system. Renal disease may sometimes be associated to these clinical manifestations. Prevalence of the nephritis is highly variable, depending on the series. More rarely, other organs such as the lungs, the heart or the nervous system may be involved. The clinical diagnosis is confirmed by histopathology of the skin (leukocytoclastic vasculitis) and kidney (endo-capillary proliferative glomerulonephritis), showing IgA deposits in these tissues. Short-term prognosis depends on the severity of digestive involvement, but long-term prognosis depends on the renal disease. Recent publications of pediatric and adult series show that the chronic renal failure may progress, sometimes more than ten years after the initial flare. Treatment is usually supportive. The benefit of more specific treatments (corticosteroids or immunosuppressive drugs) in severe visceral forms (usually abdominal or kidney) has not yet been established.

[The French medecine pricing committee].

Giorgi, D

2017-09-01

The French medicine pricing committee (CEPS) has to reconcile several major constraints, including optimal patient access to medicines and a good control of expenditures on reimbursable medicines. From 2013 to 2015, drug price decreases and discounts obtained by CEPS contributed more than € 5 billion to the balance of the health insurance accounts. As for price setting, there is a significant drop in the prices of medicines in France once they are registered for reimbursement. France is affected by a limited, but costly, flow of innovative medicines, whose prices are higher than those of previous generations, a reflection of an international gradient to which France is obviously subject, despite prices that remain at the low end of the range in Western Europe. The provision of innovative medicines for all patients who need them has been ensured in France over the last fifteen years at a controlled cost. But with the arrival of new expensive products, a resolute policy of control of expenditures must take over from the fall in prices, and original financing channels will have to be explored.

[Repetitive transcranial magnetic stimulation: A potential therapy for cognitive disorders?

PubMed

Nouhaud, C; Sherrard, R M; Belmin, J

2017-03-01

Considering the limited effectiveness of drugs treatments in cognitive disorders, the emergence of noninvasive techniques to modify brain function is very interesting. Among these techniques, repetitive transcranial magnetic stimulation (rTMS) can modulate cortical excitability and have potential therapeutic effects on cognition and behaviour. These effects are due to physiological modifications in the stimulated cortical tissue and their associated circuits, which depend on the parameters of stimulation. The objective of this article is to specify current knowledge and efficacy of rTMS in cognitive disorders. Previous studies found very encouraging results with significant improvement of higher brain functions. Nevertheless, these few studies have limits: a few patients were enrolled, the lack of control of the mechanisms of action by brain imaging, insufficiently formalized technique and variability of cognitive tests. It is therefore necessary to perform more studies, which identify statistical significant improvement and to specify underlying mechanisms of action and the parameters of use of the rTMS to offer rTMS as a routine therapy for cognitive dysfunction.

Dzierzynski, N; Stankovic Stojanovic, K; Georgin-Lavialle, S; Lionnet, F

2016-02-01

Sickle cell patients in acute pain situation experiment cognitive, behavioral and emotional changes that can accentuate their pain and disrupt communication with caregivers. On the other hand, caregivers have to face pain assessment difficulties and their own psychological reactions to their patient's pain. The gap between the patient's experience and caregiver's evaluation can lead to conflict and non-adherence treatment, and have a direct impact on the sickle cell disease prognosis. There is nothing inevitable about these phenomena, whose knowledge allows the action and opens up prospects for improving the management of sickle cell disease pain. This article is a narrative review updating the interactions between acute pain and some configurations, such as the inability to discern emotions, catastrophizing, post-traumatic stress or feeling ostracized. The overestimation of patient's addiction by caregivers also influences the pain itself. Open communication, as well as some treatments, medicated or not, a consistent institutional organization and a multidisciplinary approach altogether have an analgesic role by acting on pain cognitive and emotional components.

Improving influenza vaccination coverage has been, and still remains a challenge internationally. There are now many examples where countries have pursued a pharmacist-led influenza vaccination service in order to enhance vaccination coverage of at-risk populations. England, Portugal and the United States are successful examples where their experience implementing this service can now be explored retrospectively and learnt from. This review aims to provide evidence to help overcome barriers to commissioning and implementation of such services in countries new to the experience. Implementation is influenced by differing regulatory frameworks underpinning the provision of pharmacist-led influenza vaccination, methods of remuneration, training, and operating procedures. Practical aspects such as the facilities required, how patient records are maintained and how patients and other healthcare professionals are engaged also have an impact. These examples illustrate how community pharmacists can be trained to deliver influenza vaccinations safely, and coupled with their accessibility and convenience, can provide a complementary service to that already provided by family doctors and nurses to deliver influenza vaccinations for the benefit of patients.

2017-09-01

Splenic abscess is septic collection which occurs after haematogenous spread or local dissemination. Splenic abscess is an uncommon and rare condition, more frequently affecting male and immunocompromised patients. There are no guidelines regarding its diagnosis and management. Computed tomography (CT) scan is highly sensitive and specific (95% and 92%, respectively) in the diagnosis of splenic abscess. Diagnosis is based on blood cultures which are positive in 24 to 80% of cases. Bacterial growth culture of abscess after drainage is more efficient (50-80%) and can be performed after surgery or percutaneous drainage under imaging, including CT scan. Microorganisms involved are frequently enterobacteriaceae, gram-positive cocci and anaerobes. This particular ecology leads to an empiric broad-spectrum antibiotic therapy, with a variable duration, from 10days to more than one month. Management remains very close to the one applied in case of liver abscesses. The role of splenectomy in the prevention of recurrence remains controversial. We reviewed the literature regarding splenic abscesses, from diagnosis to therapy. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

The Groupe de Pédiatrie Générale (General Pediatrics Group), a member of the Société française de pédiatrie (French Pediatrics Society), has proposed guidelines for families and doctors regarding children's use of digital screens. A number of guidelines have already been published, in particular by the French Academy of Sciences in 2013 and the American Academy of Pediatrics in 2016. These new guidelines were preceded by an investigation into the location of digital screen use by young children in France, a survey of medical concerns on the misuse of digital devices, and a review of their documented benefits. The Conseil Supérieur de l'Audiovisuel (Higher Council on Audiovisual Technology) and the Union Nationale de Associations Familiales (National Union of Family Associations) have taken part in the preparation of this document. Five simple messages are proposed: understanding without demonizing; screen use in common living areas, but not in bedrooms; preserve time with no digital devices (morning, meals, sleep, etc.); provide parental guidance for screen use; and prevent social isolation.

The International Conference on Heavy Ion Collisions in the LHC Era was held in Quy Nhon, Vietnam, on 16-20 July 2012. The series Rencontres du Vietnam, created by Jean Tran Thanh Van in 1993, consists of international meetings aimed to stimulate the development of advanced research in Vietnam and more generally in South East Asia, and to establish collaborative research networks with Western scientific communities. This conference, as the whole series, also supports the International Center for Interdisciplinary Science Education being built in Quy Nhon. The articles published in this volume present the latest results from the heavy-ion collision programs of RHIC and LHC as well as the corresponding theoretical interpretation and future perspectives. Lower energy nuclear programs were also reviewed, providing a rather complete picture of the state-of-the-art in the field.

FRIPON (Fireball Recovery and InterPlanetary Observation Network) [4](Colas et al, 2014) was recently founded by ANR (Agence Nationale de la Recherche). Its aim is to connect meteoritical science with asteroidal and cometary science in order to better understand solar system formation and evolution. The main idea is to set up an observation network covering all the French territory to collect a large number of meteorites (one or two per year) with accurate orbits, allowing us to pinpoint possible parent bodies. 100 all-sky cameras will be installed at the end of 2015 forming a dense network with an average distance of 100km between stations. To maximize the accuracy of orbit determination, we will mix our optical data with radar data from the GRAVES beacon received by 25 stations [5](Rault et al, 2015). As both the setting up of the network and the creation of search teams for meteorites will need manpower beyond our small team of professionals, we are developing a citizen science network called Vigie-Ciel [6](Zanda et al, 2015). The public at large will thus be able to simply use our data, participate in search campaigns or even setup their own cameras.

Effect of the band structure in a rigorous two-body model with long-range interactions in 1D optical lattices

NASA Astrophysics Data System (ADS)

Kristensen, Tom; Simoni, Andrea; Launay, Jean-Michel

2016-05-01

We compute scattering and bound state properties for two ultracold molecules in a pure 1D optical lattice. We introduce reference functions with complex quasi-momentum that naturally account for the effect of excited energy bands. Our exact results for a short-range interaction are first compared with the simplest version of the standard Bose-Hubbard (BH) model. Such comparison allows us to highlight the effect of the excited bands, of the non-on-site interaction and of tunneling with distant neighbor, that are not taken into account in the BH model. The effective interaction can depend strongly on the particle quasi-momenta and can present a resonant behavior even in a deep lattice. As a second step, we study scattering of two polar particles in the optical lattice. Peculiar Wigner threshold laws stem from the interplay of the long range dipolar interaction and the presence of the energy bands. We finally assess the validity of an extended Bose-Hubbard model for dipolar gases based on our exact two-body calculations. This work was supported by the Agence Nationale de la Recherche (Contract No. ANR-12-BS04-0020-01).

Long-term industrial management of radioactive waste in France is carried out by the Agence Nationale pour la Gestion des Dechets Radioactifs (ANDRA). ANDRA is in charge of design, siting, construction, and operation of disposal centers. The solution selected in France for the disposal of low- and medium-level, short-lived radioactive waste is near-surface disposal in the earth using the principle of multiple barriers, in accordance with national safety rules and regulations, and based on operating experience from the Centre de Stockage de la Manche. Since the center's start-up in 1969, 400,000 m{sup 3} of waste have been disposed of. The Frenchmore » national program for waste management is proceeding with the construction of a second near-surface disposal, which is expected to be operational in 1991. It is located in the department of AUBE (from which its name derives), 100 miles southeast of Paris. The paper describes the criteria for siting and design of the AUBE disposal facility, design of the AUBE facility disposal module, and comparison with North Carolina and Pennsylvania disposal facility designs.« less

Identify the training profile and the published evidences about the roles and the impacts of hospital pharmacists in medical devices. A literature review was conducted using Google, Google Scholar and Pubmed for 1990-2016 associated with a manual search conducted in three non-indexed pharmaceutical journals for 2000-2016. The analysis of training programs available did not allow us to identify a specific training profile. A total of 72 articles related to the roles and the impacts of the pharmacist were identified, 52 of which came from non-indexed journals. Those articles did not deal specifically about the roles and the impacts of pharmacist; however, articles were analyses for three spheres including the referencing of medical devices (n=36), the evaluation (n=19) and the distribution system (n=13). French pharmacists have many theoretical and practical training opportunities. There are a few articles describing precisely the roles and the impacts of hospital pharmacists in medical device. It appears urgent to better document this activity in professional and indexed literature. Copyright © 2017 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.

Le sujet de cette these porte sur l'elaboration du nouveau nanomateriau par la gravure electrochimique bipolaire (BEE) --- le Ge mesoporeux et sur l'analyse de ses proprietes physico-chimiques en vue de son utilisation dans des applications photovoltaiques. La formation du Ge mesoporeux par gravure electrochimique a ete precedemment rapportee dans la litterature. Cependant, le verrou technologique important des procedes de fabrication existants consistait a obtenir des couches epaisses (superieure a 500 nm) du Ge mesoporeux a la morphologie parfaitement controlee. En effet, la caracterisation physico-chimique des couches minces est beaucoup plus compliquee et le nombre de leurs applications possibles est fortement limite. Nous avons developpe un modele electrochimique qui decrit les mecanismes principaux de formation des pores ce qui nous a permis de realiser des structures epaisses du Ge mesoporeux (jusqu'au 10 mum) ayant la porosite ajustable dans une large gamme de 15% a 60%. En plus, la formation des nanostructures poreuses aux morphologies variables et bien controlees est desormais devenue possible. Enfin, la maitrise de tous ces parametres a ouvert la voie extremement prometteuse vers la realisation des structures poreuses a multi-couches a base de Ge pour des nombreuses applications innovantes et multidisciplinaires grace a la flexibilite technologique actuelle atteinte. En particulier, dans le cadre de cette these, les couches du Ge mesoporeux ont ete optimisees dans le but de realiser le procede de transfert de couches minces d'une cellule solaire a triple jonctions via une couche sacrificielle en Ge poreux.

An x-ray grating spectrometer was built in order to measure opacities in the 50 eV to 250 eV spectral range with an average spectral resolution {approx} 50. It has been used at the LULI-2000 laser facility at Ecole Polytechnique (France) to measure the {Delta}n = 0, n = 3 transitions of several elements with neighboring atomic number: Cr, Fe, Ni, and Cu in the same experimental conditions. Hence a spectrometer with a wide spectral range is required. This spectrometer features one line of sight looking through a heated sample at backlighter emission. It is outfitted with one toroidal condensing mirrormore » and several flat mirrors cutting off higher energy photons. The spectral dispersion is obtained with a flatfield grating. Detection consists of a streak camera sensitive to soft x-ray radiation. Some experimental results showing the performance of this spectrometer are presented.« less

Since the days of MacArthur, three-dimensional (3-D) structural information on the environment has fundamentally transformed scientific understanding of ecological phenomena (MacArthur and MacArthur 1961). Early data on ecosystem structure were painstakingly laborious to collect. However, as reviewed and reported in recent volumes of Frontiers(eg Vierling et al. 2008; Asner et al.2011), advances in light detection and ranging (LiDAR) remote-sensing technology provide quantitative and repeatable measurements of 3-D ecosystem structure that enable novel ecological insights at scales ranging from the plot, to the landscape, to the globe. Indeed, annual publication of studies using LiDAR to interpret ecological phenomena increased 17-fold during the past decade, with over 180 new studies appearing in 2010 (ISI Web of Science search conducted on 23 Mar 2011: [{lidar AND ecol*} OR {lidar AND fores*} OR {lidar AND plant*}]).

Impact of the water symmetry factor on humidification and cooling strategies for PEM fuel cell stacks

NASA Astrophysics Data System (ADS)

Picot, D.; Metkemeijer, R.; Bezian, J. J.; Rouveyre, L.

In this paper, experimental water and thermal balances with three proton exchange membrane fuel cells (PEMFC) are proposed. On the test facility of Ecole des Mines de Paris, three De Nora SPA fuel cell stacks have been successfully studied: An 1 kW e prototype using Nafion® 117, a 5 and a 10 kW e module using Nafion® 115. The averaged water symmetry factor determines strategies to avoid drying membrane. So, we propose analytical solutions to find compromises between humidification and cooling conditions, which determines outlet temperatures of gases. For transport applications, the space occupied by the power module must be reduced. One of the main efforts consists in decreasing the operative pressure. Thus, if adequate cooling power is applied, we show experimentally and theoretically the possibility to use De Nora PEM fuel cells with low pressure, without specific external humidification.

The investigation of a recombining laser plasma is topical primarily because it can be used to simulate the interaction between plasma jets in astrophysical objects. It has been shown that the relative intensities of transitions of a resonance series of He-like multicharged ions can be used for the diagnostics of the recombining plasma. It has been found that the intensities of the indicated transitions for ions with the nuclear charge number Z n ~ 10 are sensitive to the plasma density in the range N e ~ 1016-1020 cm-3 at temperatures of 10-100 eV. The calculations performed for the F VIII ion have determined the parameters of plasma jets created at the ELFIE nanosecond laser facility (Ecole Polytechnique, France) in order to simulate astrophysical phenomena. The resulting universal calculation dependences can be used to diagnose different recombining plasmas containing helium-like fluorine ions.

A study on the relationship between the ANDEM--Agence Nationale pour le Développement de l'Evaluation Médicale (French agency for the development of health technology assessment) and the learned societies showed that a definition of the role of these organisations and criteria to define learned societies were lacking. We conducted a survey among the learned societies in the field of medicine so as to elaborate a definition. We used the files of the learned societies of the Anaes--Agence Nationale d'Accréditation et d'Evaluation en Santé (French Agency for accreditation and evaluation in health) in 1998, which included 225 organisations. We sent a letter together with a single-page questionnaire and copies of the 2 publications on the relationship between the ANDEM and the learned societies. To analyse the suggestions for a definition, having read the replies, a segmentation of the population, the means and modalities of action and the aims and fields of action were used. A proposal for a definition was discussed during 2002/2003 with the board of the Fédération des Spécialités Médicales (FSM) (Federation of medical specialties) regrouping 33 medical and 12 surgical societies. Three meetings between a representative of the Anaes and the board of the FSM resulted in the proposition of so-called "validation" criteria for learned societies. A search on the French Internet listing such societies was made using a research motor (March 20, 2004). Out of the 225 organisations contacted, 129 (57%) replied. Among the latter, 115 considered themselves as a learned society and 14 did not. Among the 115 organisations defining themselves as a learned society, 97 proposed a definition, 16 made use of the definitions proposed in the questionnaire and 81 proposed their own definition. The analysis identified 6 important elements (reporting, knowledge, education, research, diffusion, promotion). The data analysed permitted the elaboration of a definition based on the

Two yeast strains (FMCC Y-1(T) and FMCC Y-2) were recovered during a survey of the yeast biota associated with fermenting black olives, collected from an olive tree (Olea europaea L. cv. 'Conservolea') orchard in Central Greece. Phylogenetic analysis based on rRNA gene sequences (18S, 26S, and 5.8S-ITS) indicated that the two strains represent a separate species within the Candida membranifaciens clade, in close relation to Candida blattariae NRRL Y-27703(T). Electrophoretic karyotyping and physiological analysis support the affiliation of the two strains to a novel species as Candida olivae sp. nov. The novel strains are conspecific with two Candida sp. strains previously isolated from the Mid-Atlantic Ridge hydrothermal fields [Gadanho & Sampaio (2005). Microb Ecol 50, 408-417], indicating that Candida olivae sp. nov. may occupy diverse ecological niches. FMCC Y-1(T) (=CBS 11171(T) =ATCC MYA-4568(T)) is the type strain.

Oil spills due to oil pipelines is a very frequent problem in Mexico. Petroleos Mexicanos (PEMEX), very concerned with the environmental agenda, has been developing inspection and correction plans for zones around oil pipelines pumping stations and pipeline right-of-way. These stations are located at regular intervals of kilometres along the pipelines. In this study, two sections of an oil pipeline and two pipeline pumping stations zones are characterized in terms of the presence of Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs). The study comprehends sampling of the areas, delimitation of contamination in the vertical and horizontal extension, analysis of the sampled soils regarding TPHs content and, in some cases, the 16 PAHs considered as priority by USEPA, calculation of areas and volumes contaminated (according to Mexican legislation, specifically NOM-EM-138-ECOL-2002) and, finally, a proposal for the best remediation techniques suitable for the contamination levels and the localization of contaminants.

[On "early pathologic anatomy" and "anatomy of medical structure": continuity or point of epistemological rupture?].

PubMed

Lellouch, Alain

2006-06-01

The aim of this paper is to analyse the technical, conceptual and institutional changes from which, through macroscopic pathology, a new medical science (microscopic pathology) emerged. The "early" pathology was mainly implemented by the Ecole de Paris, at the beginning of the 19th century. After 1850, histo-pathology emerged, in German university institutes (which were separate buildings from the wards and from the dissecting rooms of the hospitals). The birth of histo-pathology is also linked with technical improvements in mass manufactured microscopes, with better techniques for fixing and staining histological samples and lastly, in (1848) withVirchow's cellular theory. Among French doctors, only one, the very famous physician Jean-Martin Charcot (1825-1893) was aware of these dramatic changes. Charcot wrote many texts which are testimonies of an epistemological rupture between two very different types of medicine, the old French "médecine d'hôpital" and the new "lab medicine", developed in German speaking countries and based on the microscope.

The Biomolecular Screening Facility (BSF) is a multidisciplinary laboratory created in 2006 at the Ecole Polytechnique Federale de Lausanne (EPFL) to perform medium and high throughput screening in life sciences-related projects. The BSF was conceived and developed to meet the needs of a wide range of researchers, without privileging a particular biological discipline or therapeutic area. The facility has the necessary infrastructure, multidisciplinary expertise and flexibility to perform large screening programs using small interfering RNAs (siRNAs) and chemical collections in the areas of chemical biology, systems biology and drug discovery. In the framework of the National Centres of Competence in Research (NCCR) Chemical Biology, the BSF is hosting 'ACCESS', the Academic Chemical Screening Platform of Switzerland that provides the scientific community with chemical diversity, screening facilities and know-how in chemical genetics. In addition, the BSF started its own applied research axes that are driven by innovation in thematic areas related to preclinical drug discovery and discovery of bioactive probes.

Topological gapped edge states in fractional quantum Hall-superconductor heterostructures

NASA Astrophysics Data System (ADS)

Cook, Ashley; Repellin, Cécile; Regnault, Nicolas; Neupert, Titus

We propose and implement a numerical setup for studying edge states of fractional quantum Hall droplets with a superconducting instability. We focus on a time-reversal symmetric bilayer fractional quantum Hall system of Laughlin ν = 1 / 3 states. The fully gapped edges carry a topological parafermionic degree of freedom that can encode quantum information protected against local perturbations. We numerically simulate such a system using exact diagonalization by restricting the calculation to the Laughlin quasihole subspace. We study the quantization of the total charge on each edge and show that the ground states are permuted by spin flux insertion and the parafermionic Josephson effect, evidencing their topological nature and the Cooper pairing of fractionalized quasiparticles.

Simulating the evolution of non-point source pollutants in a shallow water environment.

PubMed

Yan, Min; Kahawita, Rene

2007-03-01

Non-point source pollution originating from surface applied chemicals in either liquid or solid form as part of agricultural activities, appears in the surface runoff caused by rainfall. The infiltration and transport of these pollutants has a significant impact on subsurface and riverine water quality. The present paper describes the development of a unified 2-D mathematical model incorporating individual models for infiltration, adsorption, solubility rate, advection and diffusion, which significantly improve the current practice on mathematical modeling of pollutant evolution in shallow water. The governing equations have been solved numerically using cubic spline integration. Experiments were conducted at the Hydrodynamics Laboratory of the Ecole Polytechnique de Montreal to validate the mathematical model. Good correspondence between the computed results and experimental data has been obtained. The model may be used to predict the ultimate fate of surface applied chemicals by evaluating the proportions that are dissolved, infiltrated into the subsurface or are washed off.

Comparison of two different approaches for the control of convectively unstable flows

NASA Astrophysics Data System (ADS)

Juillet, Fabien; Schmid, Peter; McKeon, Beverley; Huerre, Patrick

2011-11-01

The probably most widely used control strategy in the literature is based on the Linear Quadratic Gaussian (LQG) framework. However, this approach seems to be difficult to apply to some fluid systems. In particular, due to their high sensitivity to external noise, amplifier flows are hard to control and the classical LQG compensator may be unable to describe the noise with sufficient accuracy. Another strategy aims at directly measuring these noise sources through a sensor called ``spy.'' The LQG and the spy approaches will be presented and compared using the Ginzburg-Landau equation as a model. It will be shown that the use of a spy is particularly relevant for convectively unstable systems. In addition, the ability of Subspace Identification Methods to provide satisfactory models is demonstrated. Finally, the findings from the Ginzburg-Landau investigation are generalized and applied to a more realistic system, namely a backward-facing step at Re = 350 .

In order to study the interactions of green lacewings toxocenosis on natural ecossystems, samplings were carried out in the Parque Ecológico Quedas do Rio Bonito, located in Lavras, Alto Rio Grande region, South of Minas Gerais, Brazil. The species inventory was accomplished in two vegetation types: semi-evergreen forest and open field formations, including areas of montane grassland, rocky montane grassland and "cerrado". Insects were captured with a butterfly net during 2h, walking through each vegetation formation. Sampling resulted in 1,948 specimens belonging to 30 species, of which 14 were Chrysopini and 16 Leucochrysini. Representatives of these tribes were observed both in forest and in open field formations. Species of the genera Ceraeochrysa, Chrysoperla, Chrysopodes, Plesiochrysa and Leucochrysa were found in forests and in open field formations, except for Plesiochrysa. The highest richness and diversity of species were observed in the forest. The similarity index among the communities of green lacewings in the studied areas was 27%.

The samples were collected on a monthly basis from June 2005 to May 2006, taken to the laboratory and incubated in moist chambers. Higher number of taxa was observed in the excrements of tapir, followed by deer and donkey. The highest number of species was detected for Mucor, followed by Pilobolus. Statistical analyses showed significant differences in richness of Zygomycetes taxa between the herbivore dung types. Differences of species composition, however, were weak. Seasonality influenced the Zygomycetes species composition but not its richness. Variations in taxa composition between ruminants and non-ruminants dung were non significant. PMID:24031609

Deficiency of adenosine deaminase 2 (DADA2) is a recently described auto-inflammatory disorder. It is an autosomal recessive inherited disease, caused by mutations in the ADA2 gene (formerly known as CECR1) encoding ADA2 enzyme. Besides its role in the purine metabolism, it has been postulated that ADA2 may act as a growth factor for endothelial cells and in the differenciation of monocytes. Thus, deficiency of ADA2 would lead to endothelial damage and a skewing of monocytes into M1 pro-inflammatory macrophage, causing DADA2 manifestations. Three core clinical features have been described: inflammatory-vascular signs, hematologic abnormalities and immunodeficiency. Clinically, patients display intermittent fever, cutaneous vascular manifestations, such as livedo, ischemic strokes, arthralgia and abdominal pain crisis. Corticosteroids and immunosuppressive agents (i.e. cyclophosphamide, azathioprine, ciclosporin, methotrexate) appear to be poorly effective. Although the mechanism has not been elucidated, anti-TNF agents have been proven efficient in DADA2 and should therefore be used as first line therapy for vasculitis. Role of anti-platelet and anticoagulant therapies in stroke-prophylaxis remains to be discussed, as those patients display a high risk of intracranial bleeding.

[Management of neuropathic pain].

Lozeron, P; Kubis, N

2015-07-01

Neuropathic pain is often underestimated and not adequately treated. The DN4 scale is very useful for its identification since it will benefit from pharmacological and non-pharmacological specific alternative care. The pathophysiological mechanisms involve the hyperexcitability of nociceptive pathways or decreased inhibitory descending controls that will be the target of pharmacological treatments. Frontline molecules are antidepressants (tricyclics and mixed serotonin and norepinephrine reuptake inhibitors) and antiepileptics (α2δ calcium channel inhibitors). However, these drugs will only have a partial efficacy on pain. The therapeutic strategy is based on reasonable goals, starting with a monotherapy adapted to the patient's symptoms and comorbidities and increased step by step. Patient compliance to contract is essential and requires clear and complete information. The impact on profession, social and family integration should rapidly be taken into account. In case of inefficiency, a change of the first-line treatment or an association could be considered. Some indications justify a specific therapy. Patients with resistant chronic pain should be sent to a specialized centre. New drugs are being studied and non-pharmacological support must be evaluated.

Eye involvement in Behçet's disease (BD) is frequent and an important cause of morbidity. The mean age at onset of uveitis is between 20 and 30 years in male and 30 years in female patients. Ocular involvement includes anterior, posterior or panuveitis. Uveitis may be the presenting manifestation of the disease in 20% of cases or may appear 2 or 3 years after the disease onset. The estimated risk of blindness at 5 years ranges from 15 to 25%. The main goals in the management of patients with BD uveitis are the rapid control of intraocular inflammation, the prevention of recurrent attacks, the achievement of complete remission, and preservation of vision. The medical treatment of patients with severe uveitis relies on the use of systemically administered drugs, including corticosteroids and cytotoxic agents. Anti-TNF agents and interferon-alpha seem to be efficient and well-tolerated alternative therapeutic options. Controlled clinical trials are mandatory to define the place of these new immunomodulatory agents in the therapeutic strategy, and especially their use as first-line therapy.

[Management of mesenteric ischemia in the era of intestinal stroke centers: The gut and lifesaving strategy].

PubMed

Nuzzo, A; Corcos, O

2017-09-01

Mesenteric ischemia is a gut and life-threatening, medical and surgical, digestive and vascular emergency. Mesenteric ischemia is the result of an arterial or venous occlusion, a vasospasm secondary to low-flow states in intensive care patients, aortic clamping during vascular surgery or intestinal transplantation. Progression towards mesenteric infarction and its complications is unpredictable and correlates with high rates of mortality or a high risk of short bowel syndrome in case of survival. Thus, mesenteric ischemia should be diagnosed and treated at an early stage, when gut injury is still reversible. Diagnostic workup lacks sensitive and specific clinical and biological marker. Consequently, diagnosis and effective therapy can be achieved by a high clinical suspicion and a specific multimodal management: the gut and lifesaving strategy. Based on the model of ischemic stroke centers, the need for a multidisciplinary and expert 24/24 emergency care has led, in 2016, to the inauguration of the first Intestinal Stroke Center (Structure d'urgences vasculaires intestinales [SURVI]) in France. This review highlights the pathophysiological features of chronic and acute mesenteric ischemia, as well as the diagnosis workup and the therapeutic management developed in this Intestinal Stroke Center.

To secure medical devices' management, the implementation of automated dispensing system in surgical service has been realized. The objective of this study was to evaluate security, organizational and economic impact of installing automated dispensing system for medical devices (ASDM). The implementation took place in a cardiac surgery department. Security impact was assessed by comparing traceability rate of implantable medical devices one year before and one year after installation. Questionnaire on nurses' perception and satisfaction completed this survey. Resupplying costs, stocks' evolution and investments for the implementation of ASDM were the subject of cost-benefit study. After one year, traceability rate is excellent (100%). Nursing staffs were satisfied with 87.5% by this new system. The introduction of ASDM allowed a qualitative and quantitative decrease in stocks, with a reduction of 30% for purchased medical devices and 15% for implantable medical devices in deposit-consignment. Cost-benefit analysis shows a rapid return on investment. Real stock decrease (purchased medical devices) is equivalent to 46.6% of investment. Implementation of ASDM allows to secure storage and dispensing of medical devices. This system has also an important economic impact and appreciated by users.

Juvenile dermatomyositis is the leading cause of chronic idiopathic inflammatory myopathy of auto-immune origin in children. Lung involvement in inflammatory myopathies is well described in adults, involving mostly interstitial lung disease, aspiration pneumonia and alveolar hypoventilation. We propose to describe its specificities in children. Pulmonary involvement may be asymptomatic and therefore must be systematically screened for. In case of clinical or functional respiratory abnormality, a chest computed tomographic (CT) scan is necessary. In children, a decrease of respiratory muscle strength seems common and should be systematically and specifically searched for by non-invasive and reproducible tests (sniff test). Interstitial lung disease usually associates restrictive functional defect, impairment of carbon monoxide diffusion and interstitial lung disease on CT scan. As in adults, the first-line treatment of juvenile dermatomyositis is based on corticosteroids. Corticosteroid resistant forms require corticosteroid bolus or adjuvant immunosuppressive drugs (methotrexate or cyclosporine). There is no consensus in pediatrics for the treatment of diffuse interstitial lung disease. Complications of treatment, including prolonged steroid therapy, are frequent and therefore a careful assessment of the treatments risk-benefit ratio is necessary, especially in growing children.

Dinh, A; Bouchand, F; Le Monnier, A

2015-09-01

During the past 10years, Clostridium difficile infections (CDI) have become a major public health challenge. Their epidemiology has changed with a rise in the number of cases and an increase in severe episodes. Recurrence and failure of conventional treatments have become more common. Furthermore, a spread of CDI has been observed in the general population-involving subjects without the usual risk factors (unexposed to antibiotic treatment, young people, pregnant women, etc.). All these change are partially due to the emergence of the hypervirulent and hyperepidemic clone NAP1/B1/027. New therapeutic strategies (antimicrobial treatment, immunoglobulins, toxin chelation, fecal microbiota transplantation) are now available and conventional treatments (metronidazole and vancomycin) have been reevaluated with new recommendations. Recent studies show a better efficacy of vancomycin compared to metronidazole for severe episodes. Fidaxomicin is a novel antibiotic drug with interesting features, including an efficacy not inferior to vancomycin and a lower risk of recurrence. Finally, for multi-recurrent forms, fecal microbiota transplantation seems to be the best option. We present the available data in this review.

The PASS ("Permanence d'Accès aux Soins de Santé") are hospital-based units providing primary care services to patients who lack health care coverage. Using a "whole person" approach and providing a combination of health and social care, the PASS offer an appropriately adapted response to complex health problems within a context of marked social vulnerability and contribute to reducing health inequalities. The PASS are an example of an interdisciplinary approach to health care which contrasts with the segmentary approach typical of conventional hospital departments. Operating at the interface between primary and secondary care, the PASS have the potential to become key players in developing models of patient pathways. Their presence reduces inappropriate emergency attendances and hospitalisation by offering medical care in a timely fashion, in an outpatient-type setting. The PASS can provide a resource for research into optimum models of health care, where the social context of health needs are fully recognized and inform medical treatment appropriately. According to their potential development, PASS are living labs of an innovative organizational model of care. Copyright © 2014 Société nationale française de médecine interne (SNFMI).

This study aims to investigate the stability of florfenicol using previously developed derivative spectrophotometric methods (D 1 and D 2 ). The studied stability-indicating pararmeters included alkali (NaOH, 1M), acid (HCl, 1M), pH changes (buffer pH 2.2-11), temperature (80°C and 100°C at pH 10) and light. A constructed pH profile for the drug degradation rate revealed a significant effect of pH on the drug stability between pH ranges 8 and 11. The obtained profile indicated first order dependence of K obs on [OH - ]. Arrhenius plot at pH 10 was found linear at temperatures 80°C and 100°C with estimated activation energy of 19.35kcal/mol. The calculated rate constant (K obs ), t ½ and t 90 at 25°C were found to be 1.8×10 -3 h, 385h and 58.3h, respectively. The photostability of florfenicol was also studied by exposing the drug solution to direct sunlight during mid-day time. The obtained results reflected the instability of florfenicol under the study conditions. Copyright © 2016 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

HPLC & NMR-based forced degradation studies of ifosfamide: The potential of NMR in stability studies.

The aim of this study is to conduct a forced degradation study on ifosfamide under several stress conditions to investigate the robustness of the developed HPLC method. It also aims to provide further insight into the stability of ifosfamide and its degradation profile using both HPLC and NMR. Ifosfamide solutions (20mg/mL; n=15, 20mL) were stressed in triplicate by heating (70°C), under acidic (pH 1 & 4) and alkaline (pH 10 & 12) conditions. Samples were analysed periodically using HPLC and FT-NMR. Ifosfamide was most stable under weakly acidic conditions (pH 4). NMR results suggested that the mechanism of ifosfamide degradation involves the cleavage of the PN bond. For all stress conditions, HPLC was not able to detect ifosfamide degradation products that were detected by NMR. These results suggest that the developed HPLC method for ifosfamide did not detect the degradation products shown by NMR. It is possible that degradation products co-elute with ifosfamide, do not elute altogether or are not amenable to the detection method employed. Therefore, investigation of ifosfamide stability requires additional techniques that do not suffer from the aforementioned shortcomings. Copyright © 2015 Académie Nationale de Pharmacie.

The manipulation of drugs from glass ampules can generate particles when the ampule is broken. Several authors recommend the use of filter needle to withdraw the drug content. The aim of this study is to make an assessment of the presence of particles during the manipulation of glass ampules and to discuss the current practices. Literature review based on a search strategy (Pubmed, Google Scholar) and a summary table of available data. Analysis to evaluate the efficacy of the filtration when data are available. Eighteen articles have been included. Most of study shows the presence of particles in glass ampules. Important discrepancies reported regarding the number of particles per ampule. Analysis of data from seven studies: decrease of 83% of the total number of particles (>10μm) identified when drugs are removed with filter needle. All studies but two confirm the efficacy of filter needles. Studies show the presence of particles when drugs are removed from glass ampules. They do not allow to make a conclusion on human clinical consequences associated with the presence of particles.

In a hospital environment, the quality control of the hospital preparations allows to release homogeneous batches in a secure way. These controls are totally integrated into the process of production and can also, in certain cases, be realized for high-alert magistral preparations. In community pharmacy, these controls were not required, but the Agence régionale de santé (ARS) recently incited compounding community pharmacies to realize this type of analyses. This decision motivated the creation of a collaboration between the pharmacy department of a French teaching hospital and a society including around thirty community pharmacies having a preparatory. Twenty community pharmacies distributed on all the territory have submitted one of their pediatric preparation, capsules of captopril 2mg, to the pharmacopoeia controls usually realized in the industry or hospital. All the analyzed batches were in agreement with European Pharmacopeia specifications. We shall present the rational of this work, the results as well as the numerous perspectives offered by this new type of collaboration joining completely the logic of a network city-hospital allowing the improvement of security of the medication circuit in France.

Physical activity is a key determinant of public health and contributes to decreasing the prevalence of many diseases. Cancer is the leading cause of death worldwide. Physical activity, accessible to the entire population, could prevent up to 25% of cancers, in addition to improving survival rates and quality of life in cancer patients. Physical activity acts via various mechanisms to slow or decrease tumor growth, including the production and bioavailability of sex hormones, insulin resistance and insulin secretion, and inflammation. In primary prevention, physical activity reduces breast cancer risk by 15-20% and colorectal cancer risk by 24%. All-cause mortality is reduced by 33% in cancer survivors who exercise. Health-related quality of life, fatigue and depression are enhanced by the practice of physical activity in cancer patients. In the general population, the global recommendations on physical activity for health, published by the World Health Organisation, are suggested as a means of primary prevention of cancer. In cancer patients, an adapted physical activity routine is promoted from the very beginning of patient care to decrease fatigue as well as improve tolerance and benefits of treatments.

Worldwide, approximately 5 to 10% of the population is infected by a Human Papilloma Virus (HPV). Some of these viruses, with a high oncogenic risk (HPV HR), are responsible for about 5% of cancer. It is now accepted that almost all carcinomas of the cervix and the vulva are due to an HPV HR (HPV16 and 18) infection. However, these viruses are known to be involved in the carcinogenesis of many other cancers (head and neck [SCCHN], penis, anus). For head and neck cancer, HPV infection is considered as a good prognostic factor. The role of HPV HR in anal cancer is also extensively studied in high-risk patient's population. The role of HPV infection in the carcinogenesis of esophageal, bladder, lung, breast or skin cancers is still debated. Given the multiple possible locations of HPV HR infection, the question of optimizing the management of patients with a HPV+ cancer arises in the implementation of a comprehensive clinical and biological monitoring. It is the same in therapeutics with the existence of a preventive vaccination, for example. Copyright © 2015 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

To develop French recommendations about the management of vaccinations, the screening of cervical cancer and the prevention of pneumocystis pneumonia in systemic lupus erythematosus (SLE). Thirty-seven experts qualified in internal medicine, rheumatology, dermatology, nephrology and pediatrics have selected recommendations from a list of proposition based on available data from the literature. For each recommendation, the level of evidence and the level of agreement among the experts were specified. Inactivated vaccines do not cause significant harm in SLE patients. Experts recommend that lupus patient should receive vaccinations accordingly to the recommendations and the schedules for the general public. Pneumococcal vaccination is recommended for all SLE patients. Influenza vaccination is recommended for immunosuppressed SLE patients. Live attenuated vaccines should be avoided in immunosuppressed patients. Yet, recent works suggest that they can be considered in mildly immunosuppressed patients. Experts have recommended a cervical cytology every year for immunosuppressed patients. No consensus was obtained for the prevention of pneumocystis pneumonia. These recommendations can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of SLE patients.

Ce travail consiste en la simulation numerique des ecoulements internes compressibles bidimensionnels laminaires et turbulents. On s'interesse, particulierement, aux ecoulements dans les ejecteurs supersoniques. Les equations de Navier-Stokes sont formulees sous forme conservative et utilisent, comme variables independantes, les variables dites enthalpiques a savoir: la pression statique, la quantite de mouvement et l'enthalpie totale specifique. Une formulation variationnelle stable des equations de Navier-Stokes est utilisee. Elle est base sur la methode SUPG (Streamline Upwinding Petrov Galerkin) et utilise un operateur de capture des forts gradients. Un modele de turbulence, pour la simulation des ecoulements dans les ejecteurs, est mis au point. Il consiste a separer deux regions distinctes: une region proche de la paroi solide, ou le modele de Baldwin et Lomax est utilise et l'autre, loin de la paroi, ou une formulation nouvelle, basee sur le modele de Schlichting pour les jets, est proposee. Une technique de calcul de la viscosite turbulente, sur un maillage non structure, est implementee. La discretisation dans l'espace de la forme variationnelle est faite a l'aide de la methode des elements finis en utilisant une approximation mixte: quadratique pour les composantes de la quantite de mouvement et de la vitesse et lineaire pour le reste des variables. La discretisation temporelle est effectuee par une methode de differences finies en utilisant le schema d'Euler implicite. Le systeme matriciel, resultant de la discretisation spatio-temporelle, est resolu a l'aide de l'algorithme GMRES en utilisant un preconditionneur diagonal. Les validations numeriques ont ete menees sur plusieurs types de tuyeres et ejecteurs. La principale validation consiste en la simulation de l'ecoulement dans l'ejecteur teste au centre de recherche NASA Lewis.

Principal component analysis is applied and compared with the line ratios of special Ne-like transitions for investigating the electron beam effects on the L-shell Cu synthetic spectra. The database for the principal component extraction is created over a non Local Thermodynamic Equilibrium (non-LTE) collisional radiative L-shell Copper model. The extracted principal components are used as a database for Artificial Neural Network in order to estimate the plasma electron temperature, density, and beam fractions from a representative time-integrated spatially resolved L-shell Cu X-pinch plasma spectrum. The spectrum is produced by the explosion of 25-μm Cu wires on a compact LC (40more » kV, 200 kA, and 200 ns) generator. The modeled plasma electron temperatures are about T{sub e} ∼ 150 eV and N{sub e} = 5 × 10{sup 19} cm{sup −3} in the presence of the fraction of the beams with f ∼ 0.05 and a centered energy of ∼10 keV.« less

Are body size across the life course and adult height associated with endometriosis? Endometriosis is associated with lean body size during childhood, adolescence and adulthood; tall total adult height; and tall sitting height. The literature suggests that both adult body size and height are associated with endometriosis risk, but few studies have investigated the role of body size across the life course. Additionally, no study has investigated the relationships between components of height and endometriosis. We used a nested case-control design within E3N (Etude Epidémiologique auprès de femmes de l'Education Nationale), a prospective cohort of French women. Data were updated every 2-3 years through self-administered questionnaires. Odds ratios (ORs) and 95% CIs were computed using logistic regression models adjusted for a priori confounding factors. A total of 2416 endometriosis cases were reported as surgically ascertained among the 61 208 included women. The odds of endometriosis were lower among women who reported having a large versus lean body size at 8 years (P for trend = 0.003), at menarche (P for trend < 0.0001) and at ages 20-25 years (P for trend < 0.0001). Women in the highest quartiles of height had statistically significantly increased odds of endometriosis compared to those in the lowest (<158 cm) (162-164 cm: OR = 1.28, 95% CI = 1.12-1.46; ≥165 cm: OR = 1.33, 95% CI = 1.18-1.49, P for trend < 0.0001). Statistically significantly increased odds were also observed among women with a taller sitting height (OR = 1.24, 95% CI = 1.05-1.47, P for trend = 0.01). Leg length was not statistically significantly associated with endometriosis. Endometriosis cases may be prone to misclassification; however, we restricted our case definition to surgically-confirmed cases, which showed a high validation rate. Body size is based on retrospective self-report, which may be subject to recall bias. The results of this study suggest that endometriosis is positively

porque la Unión Internacional para la Conservación de la Naturaleza (UICN) ha desarrollado criterios objetivos, repetibles y transparentes para evaluar el riesgo de extinción que explícitamente separa la evaluación de riesgo de la definición de prioridades. En el IV Congreso Mundial de Conservación en 2008, el proceso comenzó a desarrollar e implementar estándares globales comparables para ecosistemas. Un grupo de trabajo establecido por la UICN ha formulado un sistema inicial de categorías y criterios cuantitativos, análogos a los utilizados para especies, para asignar niveles de amenaza a ecosistemas a niveles local, regional y global. Un sistema final requerirá de definiciones de ecosistemas; cuantificación del estatus de ecosistemas; identificación de las etapas de degradación y pérdida de los ecosistemas; medidas de riesgo (criterios) alternativas; umbrales de clasificación para esos criterios y métodos estandarizados para la realización de evaluaciones. El sistema deberá reflejar el nivel y tasa de cambio en la extensión, composición, estructura y funcionamiento de un ecosistema, y tener sus raíces conceptuales en la teoría ecológica y la investigación empírica. Sobre la base de esos requerimientos y la hipótesis de que el riesgo del ecosistema es una función del riesgo de las especies que lo componen, proponemos un conjunto de 4 criterios: declinaciones recientes en la distribución o funcionamiento ecológica, pérdida total histórica en la distribución o funcionamiento ecológico, distribución pequeña combinada con declinación, o distribución muy pequeña. La mayor parte del trabajo se ha concentrado en ecosistemas terrestres, pero también se requieren umbrales y criterios comparables para ecosistemas dulceacuícolas y marinos. Estos son los primeros pasos de un proceso de consulta internacional que llevará a una propuesta unificada que será presentada en el próximo Congreso Mundial de Conservación en 2012. PMID:21054525

Mapping opportunities and challenges for rewilding in Europe

Farmland abandonment takes place across the world due to socio-economic and ecological drivers. In Europe agricultural and environmental policies aim to prevent abandonment and halt ecological succession. Ecological rewilding has been recently proposed as an alternative strategy. We developed a framework to assess opportunities for rewilding across different dimensions of wilderness in Europe. We mapped artificial light, human accessibility based on transport infrastructure, proportion of harvested primary productivity (i.e., ecosystem productivity appropriated by humans through agriculture or forestry), and deviation from potential natural vegetation in areas projected to be abandoned by 2040. At the continental level, the levels of artificial light were low and the deviation from potential natural vegetation was high in areas of abandonment. The relative importance of wilderness metrics differed regionally and was strongly connected to local environmental and socio-economic contexts. Large areas of projected abandonment were often located in or around Natura 2000 sites. Based on these results, we argue that management should be tailored to restore the aspects of wilderness that are lacking in each region. There are many remaining challenges regarding biodiversity in Europe, but megafauna species are already recovering. To further potentiate large-scale rewilding, Natura 2000 management would need to incorporate rewilding approaches. Our framework can be applied to assessing rewilding opportunities and challenges in other world regions, and our results could guide redirection of subsidies to manage social-ecological systems.

Walter Meyerhof, one of the leading figures in the field of ion-atom collisions, passed away on May 27, 2006. He was 84 years old. He was born in Kiel, Germany, in the same year that his father, Otto Meyerhof, won the Nobel Prize in Medicine for his discovery of energetically important cycles in biological processes. Following his flight from Hitler-Germany in 1938, Walter Meyerhof studied from 1939-1940 at the Ecole de Physique et Chimie Industrielles in Paris, but when France too fell under Nazi occupation, he had to escape once again. In an exciting odyssey via Spain and Portugal he finally reached the United States. He received a doctorate degree in physics at the University of Pennsylvania in Philadelphia in 1946 with a thesis in solid-state physics. In the same year, he became Assistant Professor at the University of Illinois and in 1949 at Stanford University. In 1952 he was promoted to Associate Professor and in 1959 to Full Professor. From 1970 to 1977 he served as a Chairman of the Stanford Physics Department (see Fig. 1).

The comprehensive study of microorganisms that evolved in the Atacama Desert, the driest and oldest on earth, may help to understand the key role of water for life. In this context, we previously characterized the microenvironment that allows colonization of the underside of quartzes in the Coastal Range of this desert by hypolithic microorganisms (Azua-Bustos et al. Microb Ecol 58:568-581, 2011). Now, we describe the biodiversity composition of these biofilms and the isolation from it of a new cyanobacterial strain. Based on morphologic and phylogenetic analyses, this isolate (AAB1) was classified as a new member of the Gloeocapsopsis genus. Physiological, morphological and molecular responses by isolate AAB1 show that this strain is extremely tolerant to desiccation. Our results also indicate that the isolate biosynthesizes sucrose and trehalose in response to this stressful condition. We identified two candidate genes involved in sucrose synthesis, namely sucrose 6-phosphate synthase and sucrose 6-phosphate phosphatase. Thus, the Gloeocapsopsis isolate AAB1 may represent a suitable model for understanding tolerance to low water availability.

We describe a new species of nurse-frog (Aromobatidae, Allobates) from northwestern Brazilian Amazon. Allobates juami sp. nov. is distinguished from similar congeneric species by the combination of the following characters: body-size range (snout-to-vent length 17.5-18.5 mm), lack of dark pigments on ventral surfaces of male specimens, dorsal color pattern (predominantly solid dark brown, but conspicuously light brown over snout and urostyle regions), presence of conspicuous pale dorsolateral and ventrolateral stripes, and presence of a diffuse pale paracloacal mark. The advertisement call of the new species lasts 2.5-5.1 s, contains 60-73 short notes (trills), and is emitted at an average rate of 13 notes per second within trills. Duration of silent intervals between notes ranges between 0.020-0.050 s, and the peak frequency of notes ranges from 4.59 to 5.47 kHz. The new species is currently known only from the type locality at Estação Ecológica Juami-Japurá (1.96455° S, 67.93579° W; ~ 87 m a.s.l.).

This document presents a non-rigid registration algorithm for the use of brain magnetic resonance (MR) images comparison. More precisely, we want to compare pre-operative and post-operative MR images in order to assess the deformation due to a surgical removal. The proposed algorithm has been studied in Chesseboeuf et al. ((Non-rigid registration of magnetic resonance imaging of brain. IEEE, 385-390. doi: 10.1109/IPTA.2015.7367172 , 2015), following ideas of Trouvé (An infinite dimensional group approach for physics based models in patterns recognition. Technical Report DMI Ecole Normale Supérieure, Cachan, 1995), in which the author introduces the algorithm within a very general framework. Here we recalled this theory from a practical point of view. The emphasis is on illustrations and description of the numerical procedure. Our version of the algorithm is associated with a particular matching criterion. Then, a section is devoted to the description of this object. In the last section we focus on the construction of a statistical method of evaluation.

Diagnostics of recombining laser plasma parameters based on He-like ion resonance lines intensity ratios

While the plasma created by powerful laser expands from the target surface it becomes overcooled, i.e. recombining one. Improving of diagnostic methods applicable for such plasma is rather important problem in laboratory astrophysics nowadays because laser produced jets are fully scalable to young stellar objects. Such scaling is possible because of the plasma hydrodynamic equations invariance under some transformations. In this paper it is shown that relative intensities of the resonance transitions in He-like ions can be used to measure the parameters of recombining plasma. Intensity of the spectral lines corresponding to these transitions is sensitive to the density in the range of 1016-1020 cm-3 while the temperature ranges from 10 to 100 eV for ions with nuclear charge Zn ∼ 10. Calculations were carried out for F VIII ion and allowed to determine parameters of plasma jets created by nanosecond laser system ELFIE (Ecole Polytechnique, France) for astrophysical phenomenon modelling. Obtained dependencies are quite universal and can be used for any recombining plasma containing He-like fluorine ions.

Wastewater from car washes represents a potential problem for the sewer system due to its emulsified oils and suspended material. Treatment of wastewater discharged from four car washes was investigated by sedimentation and coagulation. The effect of the coagulants Servical P (aluminium hydroxychloride), Servican 50 (poly(diallyldimethylammonium chloride)), aluminium sulfate and ferric chloride was evaluated. The achieved removal using sedimentation was of 82%, 88% 73% and 51% for oils, total suspended solids, COD, and turbidity, respectively. In the treatment by coagulation we achieved average efficiencies nearly to 74% for COD removal, greater than 88% in the case of total suspended solids removal and 92% in the case of turbidity and except the performance of Servican 50 greater than 90% in oil removal. We concluded that the oil residual concentration and COD in the treated water allows pouring it in the sewer system complying with the limits of the Mexican rule NOM-002-ECOL-1996 and it is possible even its reuse, at least in the case of the chassis washing of cars.

Nowadays, the northern part of the Atlantic Rainforest of Brazil is largely destroyed and forest remnants rarely exceed 100 ha. In a 118 ha forest fragment within a state nature reserve of Pernambuco (Reserva Ecológica Gurjaú), we surveyed the orchid bee fauna (Apidae, Euglossini) using eight different scent baits to attract males. Once a month during one year, the bees were actively collected with entomological nets, from November 2002 to October 2003 by two collectors. We collected 2,908 orchid bee males belonging to 23 species, one of the highest richness values of the Northern Atlantic Rainforest. Bees of only two species, Euglossa carolina (50%) and Eulaema nigrita (25%), which occurred throughout the year, accounted for three quarter of the collected individuals. Both species are typical for open or disturbed areas. Rainforest remnants like those of Gurjaú within the predominant sugar cane monocultures in the coastal plains of the northern Atlantic Rainforest play an important role in orchid bee conservation and maintenance of biodiversity.

Cascading effects of fishing on Galapagos rocky reef communities: reanalysis using corrected data

Sonnenholzner, Jorge I.; Ladah, Lydia B.; Lafferty, Kevin D.

2009-01-01

This article replaces Sonnenholzner et al. (2007; Mar Ecol Prog Ser 343:77–85), which was retracted on September 19, 2007, due to errors in entry of data on sea urchins. We sampled 10 highly fished and 10 (putatively) lightly fished shallow rocky reefs in the southeastern area of the Galapagos Marine Reserve, Ecuador. After the correction, these are the new results: there was a negative association between slate-pencil urchins Eucidaris galapagensis and non-coralline algae. In addition, pencil urchins were less abundant where there were many predators. An indirect positive association between predators and non-coralline algae occurred. Fishing appeared to affect this trophic cascade. The spiny lobster Panulirus penicillatus, the slipper lobster Scyllarides astori, and the Mexican hogfish Bodianus diplotaenia were significantly less abundant at highly fished sites. Urchin density was higher at highly fished sites. Non-coralline algae were nearly absent from highly fished sites, where a continuous carpet of the anemone Aiptasia sp. was recorded, and the algal assemblage was mainly structured by encrusting coralline and articulated calcareous algae.

Ion-neutral chemistry at ultralow energies:Dynamics of reactive collisions between laser-cooled Ca+ or Ba+ ions and Rb atoms in an ion-atom hybrid trap

Cold chemical reactions between laser-cooled Ca+ or Ba+ ions and Rb atoms were studied in an ion-atom hybrid trap. Reaction rate constants were determined in the collision energy range Ecoll /kB = 20 mK-20 K. Product branching ratios were studied using resonant-excitation mass spectrometry. The dynamics of the reactive processes including the radiative formation of CaRb+ and BaRb+ molecular ions has been analyzed using accurate potential energy curves and quantum-scattering calculations for the radiative channels. It is shown that the energy dependence of the reaction rates is governed by long-range interactions, while its magnitude is determined by short-range non-adiabatic and radiative couplings. The quantum character of the collisions is predicted to manifest itself in the occurrence of narrow shape resonances at well-defined collision energies. The present results highlight both universal and system-specific phenomena in cold ion-neutral collisions. This work was supported by the Swiss National Science Foundation and the COST Action ''Ion Traps for Tomorrow's Applications''.

The article deals with the life and activity of J. Ch. Sournia from 1938 to 1966. Born in Bourges (France) in 1917, he studied at "l'Ecole du Service de Santé Militaire" in Lyon. In 1938 he became a non-resident student of Lyon Hospitals and a resident in 1943. Assistant of thoracic surgery by Professors Paul Santy and Marcel Bérard he underwent an advanced training course by Pr Crawford in Sweden. There he met his Swedish wife-to-be. Appointed professor of Surgery he taught Surgery in Alep and Anatomy in Beyrouth. In the same time he was interested in the History of Syria and its archeology during the Byzantine Centuries (from the IVth to the VIIth A. D.). While his wife was teaching literature at Rennes University he was appointed surgery professor at the Medical College in Rennes and wrote "the Middle-East of Primitive Christianity-History and Archaeology by Byzantine Syria" (Fayard 1966) in which he focused his study on monks who lived for long years on pillar top to be closer to God, like St Simeon.

Requirements for plant coexistence through pollination niche partitioning

PubMed Central

Benadi, Gita

2015-01-01

Plant–pollinator interactions are often thought to have been a decisive factor in the diversification of flowering plants, but to be of little or no importance for the maintenance of existing plant diversity. In a recent opinion paper, Pauw (2013 Trends Ecol. Evol. 28, 30–37. (doi:10.1016/j.tree.2012.07.019)) challenged this view by proposing a mechanism of diversity maintenance based on pollination niche partitioning. In this article, I investigate under which conditions the mechanism suggested by Pauw can promote plant coexistence, using a mathematical model of plant and pollinator population dynamics. Numerical simulations show that this mechanism is most effective when the costs of searching for flowers are low, pollinator populations are strongly limited by resources other than pollen and nectar, and plant–pollinator interactions are sufficiently specialized. I review the empirical literature on these three requirements, discuss additional factors that may be important for diversity maintenance through pollination niche partitioning, and provide recommendations on how to detect this coexistence mechanism in natural plant communities.

Here, in this paper, we detail the diagnostic technique used to infer the spatially resolved electron temperatures and densities in experiments dedicated to investigate the generation of magnetically collimated plasma jets. It is shown that the relative intensities of the resonance transitions in emitting He-like ions can be used to measure the temperature in such recombining plasmas. The intensities of these transitions are sensitive to the plasma density in the range of 10 16–10 20 cm -3 and to plasma temperature ranges from 10 to 100 eV for ions with a nuclear charge Z n ~10. We show how detailedmore » calculations of the emissivity of F VIII ions allow to determine the parameters of the plasma jets that were created using ELFIE ns laser facility (Ecole Polytechnique, France). Lastly, the diagnostic and analysis technique detailed here can be applied in a broader context than the one of this study, i.e., to diagnose any recombining plasma containing He-like fluorine ions.« less

Therapeutic innovation contributes to the increase of health care expenditures in France. Medico-economic evaluation has still a minor role in the decision-making for the registration of drugs and medical devices in hospitals. This study aimed to systematically review published works on medico-economic studies conducted within French hospitals. A literature review was carried out to search for medico-economic studies conducted by hospital teams on therapeutic or diagnostic strategies employed within French hospitals and published from 2010 to 2014. Quality assessment of selected studies was performed according to Drummond et al.'s checklist, which is also used within French guidelines. Of the 44 analyzed articles, methods for identification and measure of costs and results complied with guidelines in 95 % of cases. For results interpretation, compliance was 91 %. Costs discounting (29 %) and the use of sensitivity analysis to account for results uncertainty (70 %) were the parameters with the lowest compliance to guidelines. A good training of health professionals in using economic and statistic tools, and the transferability of results of medico-economic studies are essential and should be optimized to enable a broader use of medico-economic evaluation within the scope of decision-making in French hospitals.

Monogenic auto-inflammatory diseases are characterized by genetic abnormalities coding for proteins involved in innate immunity. They were initially described in mirror with auto-immune diseases because of the absence of circulating autoantibodies. Their main feature is the presence of peripheral blood inflammation in crisis without infection. The best-known auto-inflammatory diseases are mediated by interleukines that consisted in the 4 following diseases familial Mediterranean fever, cryopyrinopathies, TNFRSF1A-related intermittent fever, and mevalonate kinase deficiency. Since 10 years, many other diseases have been discovered, especially thanks to the progress in genetics. In this review, we propose the actual panorama of the main known auto-inflammatory diseases. Some of them are recurrent fevers with crisis and remission; some others evaluate more chronically; some are associated with immunodeficiency. From a physiopathological point of view, we can separate diseases mediated by interleukine-1 and diseases mediated by interferon. Then some polygenic inflammatory diseases will be shortly described: Still disease, Schnitzler syndrome, aseptic abscesses syndrome. The diagnosis of auto-inflammatory disease is largely based on anamnesis, the presence of peripheral inflammation during attacks and genetic analysis, which are more and more performant.

2015-11-01

Hyper-reactive malarial splenomegaly is a rare and severe form of chronic malaria. This condition is a common cause of splenomegaly in endemic areas. The pathophysiology of hyper-reactive malarial splenomegaly involves an intense immune reaction (predominantly B cell-driven) to repeated/chronic infections with Plasmodium sp. The diagnosis may be difficult, due to a poorly specific clinical presentation (splenomegaly, fatigue, cytopenias), a long delay between residence in a malaria-endemic area and onset of symptoms, and a frequent absence of parasites on conventional thin and thick blood smears. A strongly contributive laboratory parameter is the presence of high levels of total immunoglobulin M. When the diagnostic of hyper-reactive malarial splenomegaly is considered, search for anti-Plasmodium antibodies and Plasmodium nucleic acids (genus and species) by PCR is useful. Diagnosis of hyper-reactive malarial splenomegaly relies on the simultaneous presence of epidemiological, clinical, biological and follow-up findings. Regression of both splenomegaly and hypersplenism following antimalarial therapy allows the differential diagnosis with splenic lymphoma, a common complication of hyper-reactive malarial splenomegaly. Although rare in Western countries, hyper-reactive malarial splenomegaly deserves increased medical awareness to reduce the incidence of incorrect diagnosis, to prevent progression to splenic lymphoma and to avoid splenectomy.

Vignes, S; Bellanger, J

2017-08-31

Primary intestinal lymphangiectasia (PIL), Waldmann's disease, is a rare disorder of unknown etiology characterized by dilated intestinal lacteals leading to lymph leakage into the small-bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. The main symptom is bilateral lower limb edema. Edema may be moderate to severe including pleural effusion, pericarditis or ascites. Protein-losing enteropathy is confirmed by the elevated 24-h stool α1-antitrypsin clearance and diagnosis by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of biopsies. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Several B-cell lymphomas of the gastrointestinal tract or with extra-intestinal localizations were reported in PIL patients. A long-term strictly low-fat diet associated with medium-chain triglyceride and liposoluble vitamin supplementation is the cornerstone of PIL medical management. Octreotide, a somatostatin analog, have been proposed with an inconsistent efficacy in association with diet. Surgical small-bowel resection is useful in the rare cases with segmental and localized intestinal lymphangiectasia. A prolonged clinical and biological follow-up is recommended.

3D Model of Surfactant Replacement Therapy

NASA Astrophysics Data System (ADS)

Grotberg, James; Tai, Cheng-Feng; Filoche, Marcel

2015-11-01

Surfactant Replacement Therapy (SRT) involves instillation of a liquid-surfactant mixture directly into the lung airway tree. Though successful in neonatal applications, its use in adults had early success followed by failure. We present the first mathematical model of 3D SRT where a liquid plug propagates through the tree from forced inspiration. In two separate modeling steps, the plug first deposits a coating film on the airway wall which subtracts from its volume, a ``coating cost''. Then the plug splits unevenly at the airway bifurcation due to gravity. The steps are repeated until a plug ruptures or reaches the tree endpoint alveoli/acinus. The model generates 3D images of the resulting acinar distribution and calculates two global indexes, efficiency and homogeneity. Simulating published literature, the earlier successful adult SRT studies show comparatively good index values, while the later failed studies do not. Those unsuccessful studies used smaller dose volumes with higher concentration mixtures, apparently assuming a well mixed compartment. The model shows that adult lungs are not well mixed in SRT due to the coating cost and gravity effects. Returning to the higher dose volume protocols could save many thousands of lives annually in the US.

[Cryopyrine-associated periodic syndrome: CAPS seen from adulthood].

PubMed

Koné-Paut, I

2015-04-01

Cryopyrin-associated periodic syndrome is a rare hereditary periodic fever syndrome for which, the genetic mechanism, mutation in the NLRP3 gene, has allowed to gather 3 clinical phenotypes (familial cold urticaria [FCAS], Muckle-Wells syndrome [MWS], and chronic infantile neurological cutaneous and articular syndrome [CINCA]) initially described independently, and to discover the NLRP3 inflammasome, a key receptor of the innate immunity, which regulates the interleukine-1β secretion into the mononuclear cells. The clinical manifestation of CAPS : urticaria-like skin rash, eyes redness, myalgia and sensory deafness are not specific, if considered separately, and that often leads to a wandering diagnosis through a complex medical journey including various specialists. The diagnostic delay is deleterious to patients compromising their quality of life and exposing them to neurosensory complications and renal failure by secondary amyloidosis. The paediatric onset of disease, the family history, the trigger of symptoms by the cold, and the recognition of the skin rash as neutrophilic are important clues before diagnostic confirmation by genetic testing. Interleukine-1 blockade is the only effective treatment of CAPS symptoms which often may stabilize (rarely regression) the sensory involvement and in some cases may allow the regression of secondary amyloidosis.

Machine Learning to Improve the Effectiveness of ANRS in Predicting HIV Drug Resistance.

Singh, Yashik

2017-10-01

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is one of the major burdens of disease in developing countries, and the standard-of-care treatment includes prescribing antiretroviral drugs. However, antiretroviral drug resistance is inevitable due to selective pressure associated with the high mutation rate of HIV. Determining antiretroviral resistance can be done by phenotypic laboratory tests or by computer-based interpretation algorithms. Computer-based algorithms have been shown to have many advantages over laboratory tests. The ANRS (Agence Nationale de Recherches sur le SIDA) is regarded as a gold standard in interpreting HIV drug resistance using mutations in genomes. The aim of this study was to improve the prediction of the ANRS gold standard in predicting HIV drug resistance. A genome sequence and HIV drug resistance measures were obtained from the Stanford HIV database (http://hivdb.stanford.edu/). Feature selection was used to determine the most important mutations associated with resistance prediction. These mutations were added to the ANRS rules, and the difference in the prediction ability was measured. This study uncovered important mutations that were not associated with the original ANRS rules. On average, the ANRS algorithm was improved by 79% ± 6.6%. The positive predictive value improved by 28%, and the negative predicative value improved by 10%. The study shows that there is a significant improvement in the prediction ability of ANRS gold standard.

Though recommended, participation of patients with specific expertise in therapeutic education programs (TEP) is rare. This work reports the experience of a national reference centre for rare systemic diseases. Involvement of "expert patients" (EP) has been planned from the development of a TEP dedicated to systemic lupus: patients' roles and required expertise have been defined and linked to the pedagogical tools. Such patients have been recruited during individual interviews and called to participate to specific pedagogical training. EP intervention have been evaluated by questionnaire to EP and health care providers. Three EP's functions have been identified: sharing experiences, giving "tips and tricks" and promoting dialogue. EP's interventions has been organised into a hierarchy (from sharing to co-animation). Among 298 patients enrolled in the TEP, 25 (8.4%) have been identified as possible EP. Eight of them (32%) benefited from a specific training of 12 hours. Among these patients, two (25%) regularly participate to the education sessions. For EP as well as for health care providers, EP's intervention seems beneficial (visual scale scores of 7.5 and 9.5, respectively). Though difficult to organise, EP's intervention in TEP dedicated to rare systemic diseases seems useful and would earn to be increase.

Anti-leucine rich glioma inactivated 1 encephalitis is a common and a treatable etiology of autoimmune encephalitis. Its diagnosis is a challenge because the initial diagnostic work-up is often normal. A 48-year-old man experienced cognitive and behavioral troubles, facio-brachial dystonic seizures and a syndrome of inappropriate antidiuretic hormone secretion. First line tests excluded infectious, neoplastic, systemic inflammatory, endrocrine or toxic etiologies. Cerebral (18)Fluoro-desoxy-glucose (FDG) position emission tomography and research of specific antibodies in cerebro-spinal fluid and serum led to diagnose an anti-leucine rich glioma inactivated 1 encephalitis. Intravenous immunoglobulins and corticosteroids were partially effective. Cyclophosphamid permitted a good recovery. In the presence of acute neuropsychiatric disorders with a negative etiologic research, physician should think about dysimmune encephalitis. Facio-brachial dystonic seizures and syndrome of inappropriate antidiuretic hormone secretion are highly evocative of anti-leucine rich glioma inactivated 1 encephalitis. The diagnosis needs specific diagnostic tests (cerebral (18)FDG position emission tomography and antibodies research in cerebro-spinal fluid and in serum), after the exclusion of alternative diagnoses. Extensive and repeated diagnostic work-up for neoplasia is required. Immunosupressive therapies are effective in most cases. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

["Placebo effect", from personal convictions to collective representations: A psychosocial reading of a pharmacodynamic phenomenon].

Balez, R; Couturaud, F; Touffet, L

2015-11-01

After starting with a brief historical account of the placebo effect organized around the elaboration of clinical trials and around sham therapy as a method, we will offer a psychosocial point of view on the placebo phenomenon. The placebo effect is at the heart of medicine and particularly of therapeutic trials from theoretical research on a drug to its acceptance and its use in every-day clinical practice. The placebo effect intermingles biology, relationships and the context of therapeutic interactions. This type of phenomenon originates as much from biology as from human psychology. Our article puts more precisely into question the part that psychology has in the placebo phenomenon and suggests a chart to address it. This chart refers both to the pharmacodynamic effect given to drugs in a subjective way, and to the collective representations and social interactions depending on them. What can we say about the psychosociological dimensions of the placebo effect? How is it possible to organize the scope of these dimensions to base systematic studies on them in the field of clinical trials? We try to give elements of response to these questions by suggesting the study of the placebo effect as an original field of study by necessarily mobilizing both health sciences and the human and social sciences.

Smoking is the first avoidable cause of morbidity and mortality. It is estimated that there were around 14 million smokers in France in 2012 and that smoking results in 70,000 deaths per year. All types of interventions reducing with efficacy the incidence and prevalence of smoking are to consider in prolonging life expectancy. Electronic cigarettes (e.cig.) are a social phenomenon but they also are a system delivering pharmacologically active substances; their use concerns today several millions of individuals in France. By this fact, it became important for clinical practitioners to acquire some knowledge about e. cig. Most of the e.cig. contains nicotine, thus, e.cig. are now called in the medical literature as electronic nicotine delivery system (ENDS). It is highly plausible that ENDS, which are, as of today, consumer products and not health products, deliver nicotine with a good bioavailability and could, if largely used, help to reduce smoking prevalence. However, because of current lack of regulations, as of today, the risk/benefit ratio of ENDS as an aid to help smokers quit and their adverse effect profile cannot be established. It is of public health responsibility to promote evidence based knowledge about e.cig. to know with confidence their risk/benefit ratio.

Nutrient profiling ranks foods based on their nutrient content. They may help identify foods with a good nutritional quality for their price. This hypothesis was tested using diet modeling with linear programming. Analyses were undertaken using food intake data from the nationally representative French INCA (enquête Individuelle et Nationale sur les Consommations Alimentaires) survey and its associated food composition and price database. For each food, a nutrient profile score was defined as the ratio between the previously published nutrient density score (NDS) and the limited nutrient score (LIM); a nutritional quality for price indicator was developed and calculated from the relationship between its NDS:LIM and energy cost (in euro/100 kcal). We developed linear programming models to design diets that fulfilled increasing levels of nutritional constraints at a minimal cost. The median NDS:LIM values of foods selected in modeled diets increased as the levels of nutritional constraints increased (P = 0.005). In addition, the proportion of foods with a good nutritional quality for price indicator was higher (P < 0.0001) among foods selected (81%) than among foods not selected (39%) in modeled diets. This agreement between the linear programming and the nutrient profiling approaches indicates that nutrient profiling can help identify foods of good nutritional quality for their price. Linear programming is a useful tool for testing nutrient profiling systems and validating the concept of nutrient profiling.

Representation-based user interfaces for the audiovisual library of the year 2000

The audiovisual library of the future will be based on computerized access to digitized documents. In this communication, we address the user interface issues which will arise from this new situation. One cannot simply transfer a user interface designed for the piece by piece production of some audiovisual presentation and make it a tool for accessing full-length movies in an electronic library. One cannot take a digital sound editing tool and propose it as a means to listen to a musical recording. In our opinion, when computers are used as mediations to existing contents, document representation-based user interfaces are needed. With such user interfaces, a structured visual representation of the document contents is presented to the user, who can then manipulate it to control perception and analysis of these contents. In order to build such manipulable visual representations of audiovisual documents, one needs to automatically extract structural information from the documents contents. In this communication, we describe possible visual interfaces for various temporal media, and we propose methods for the economically feasible large scale processing of documents. The work presented is sponsored by the Bibliotheque Nationale de France: it is part of the program aiming at developing for image and sound documents an experimental counterpart to the digitized text reading workstation of this library.

Benefits of pharmacist-led flu vaccination services in community pharmacy.

Seasonal influenza is a major cause of excess winter deaths and increased hospital admissions. There is a high level of economic burden associated with the infection. Although vaccination targets have been set to tackle this international issue, many countries struggle to reach these coverage targets for their at-risk populations using traditional delivery methods. Traditional providers include family doctors and nurses; however, pharmacist-led influenza vaccination has become a more commonly utilised aid to support vaccination targets. Community pharmacies are convenient and widely accessible and evaluations consistently demonstrate that patients are satisfied with pharmacist-led vaccinations. Allowing community pharmacists to administer influenza vaccination as an alternative option for delivery helps to increase the coverage rate of vaccination. In addition, commissioning community pharmacists to provide this service has been shown to contribute to achieving targets for those at-risk. Pharmacist-led influenza vaccination services can create value for payors and reduce pressure on health systems. This review aims to demonstrate the success of pharmacy-led influenza vaccinations, and the impact it has had in driving up immunisation rates within other countries. Experiences of countries such as England, Portugal and the United States provide evidence to demonstrate the benefit to both the patient and the health system.

Tetanus is a serious disease, which could be potentially lethal. All cases are observed in patients inadequately immunized. The immunochromatographic tests (including Tetanos quick Stick(®) [TQS]) have demonstrated their efficiency in emergency setting. The aim of our study was to assess the usefulness of these tests in elderly outpatients seen in ambulatory settings. This prospective study included patients aged 65 years and over who presented to the outpatients' clinic of the Gerontologic Departmental Center (Marseille). A TQS and a self-administered questionnaire to assess risk factors for tetanus were performed. One hundred and twenty-two patients were studied. The prevalence of positive TQS was 66%. Patients have an average of 2.5 risk factors for tetanus. Negative TQS was observed in 35% of patients who had seen their general practitioner for a wound during the previous year. Elderly patients accumulate several risk factors regardless of age and lifestyle. While physicians are familiar with the vaccine recommendations, they are often faced with the difficulty of assessing patient's status based only on the patient's interview, which is frequently not reliable. The implementation of immunochromatographic tests in general practice could help physicians in the management of patients at risk for tetanus.

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

2016-01-01

Accidental direct intravenous injection of a concentrated solution of potassium often leads to patient death. In France, recommendations of healthcare agencies to prevent such accidents cover only preparation and intravenous infusion conditions. Accidents continue to occur in French hospitals. These facts demonstrate that these recommendations are insufficient and ineffective to prevent such deaths, especially those occurring during a catheter flushing. This article reviews the measures able to reduce the number of accidents. Countries which removed concentrated ampoules from ward stocks observed a decrease of the number of accidental deaths. This withdrawal, recommended by the World Health Organization, is now part of standards in studies aimed at determining the safety of care in hospitals. However, removal alone is insufficient to eliminate the risk. The combination with other measures should be considered. These measures are the provision of a combination of diluted intravenous ready to use solutions, the promotion of the oral route with tablets and oral solutions for potassium replenishment and to make available products with safeguards to prevent single shot intravenous injection. Studies aimed at determining the consequences on preventing concentrated potassium accidents of a widespread distribution of isotonic sodium chloride pre-filled ready-to-use syringes for catheter flushing should be performed.

2011-06-01

Clinical reasoning is a highly complex system with multiple inter-dependent mental activities. Gaining a better understanding of those cognitive processes has two practical implications: for physicians, being able to analyse their own reasoning method may prove to be helpful in diagnostic dead end; for medical teachers, identifying problem-solving strategies used by medical students may foster an appropriate individual feed-back aiming at improving their clinical reasoning skills. On the basis of a detailed literature review, the main diagnostic strategies and their related pattern of mental processes are described and illustrated with a concrete example, going from the patient's complaint to the chosen solution. Inductive, abductive and deductive diagnostic approaches are detailed. Different strategies for collecting data (exhaustive or oriented) and for problem-building are described. The place of problem solving strategies such as pattern-recognition, scheme inductive process, using of clinical script, syndrome grouping and mental hypotheses test is considered. This work aims at breaking up mental activities in process within clinical reasoning reminding that expert reasoning is characterised by the ability to use and structure the whole of these activities in a coherent system, using combined strategies in order to guarantee a better accuracy of their diagnosis.

The methodology used in the present study is inspired from project management and quality approach. Existing training supports were used to produce accreditation procedure and evaluation supports. We first defined abilities levels, from level 1, corresponding to accredited learning agent to level 3, corresponding to expert accredited agent. Elements assessed for accreditation are: clothing assessment either by practices audit or by microbiologic test, test bags preparation and handling assessment, bag production to assess aseptic filling for both manual or automatized method, practices audit, number of days of production, and non-conformity following. At Angers Hospital, in 2014, production staff is composed of 12 agents. Staff accreditation reveals that 2 agents achieve level 3, 8 agents achieve level 2 and 2 agents are level 1. We noted that non-conformity decreased as accreditation took place from 81 in 2009 to 0 in 2014. To date, there is no incident due to parenteral bag produced by Angers hospital for neonatal resuscitation children. Such a consistent study is essential to insure a secured nutrition parenteral production. This also provides a satisfying quality care for patients. Copyright © 2016 Académie Nationale de Pharmacie.
