    Prostate cancer is the most frequently diagnosed malignancy in men and the second highest contributor of male cancer mortality. The crude extract of Euphorbia formosana (CEEF) has been used for treatment of different diseases but the cytotoxic effects of CEEF on human cancer cells have not been reported. The purpose of the present experiments was to determine effects of CEEF on cell cycle distribution and induction of apoptosis in DU145 human prostate cancer cells in vitro. Contrast-phase microscope was used for examining cell morphological changes. Flow cytometric assays were used for cell viability, cell cycle, apoptosis, reactive oxygen species, and Ca(2+) production and mitochondria membrane potential (ΔΨm ). Western blotting was used for examining protein expression of cell cycle and apoptosis associated proteins. Real-time PCR was used for examining mRNA levels of caspase-3, -8, and -9, AIF, and Endo G. Confocal laser microscope was used to examine the translocation of AIF, Endo G, and cytochrome in DU145 cells after CEEF exposure. CEEF-induced cell morphological changes, decreased the percentage of viable cells, and induced S phase arrest and apoptosis in DU145 cells. Furthermore, CEEF promoted RAS and Ca(2+) production and reduced ΔΨm levels. Real-time QPCR confirmed that CEEF promoted the mRNA expression of caspase-3 and -9, AIF and Endo G and we found that AIF and Endo G and cytochrome c were released from mitochondria. Taken together, CEEF-induced cytotoxic effects via ROS production, induced S phase arrest and induction of apoptosis through caspase-dependent and independent and mitochondria-dependent pathways in DU245 cancer cells. © 2015 Wiley Periodicals, Inc.

    Huang-Lian-Jie-Du-Decoction (HLJDD, Oren-gedoku-to in Japanese) is commonly used in traditional Chinese medicine (TCM) to treat ischemic stroke. This study investigated the efficacy of various combinations of the major components of HLJDD, berberine (A), baicalin (B), and jasminoidin (C), on the treatment of ischemic stroke modeled by middle cerebral artery occlusion (MCAO) in rats. The effects of A, B and C individually and their combinations were investigated using proton nuclear magnetic resonance (1H NMR)-based metabolomics complemented with neurologic deficit scoring, infarct volume measurement, biochemistry, histopathology and immunohistochemistry, as well as quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting. Ischemic stroke produces severe oxidative stress, which induces further damage. Our results show that the ABC combination treatment increased levels of cellular antioxidants that scavenged reactive oxygen species during ischemia-reperfusion via the nuclear erythroid 2-related factor 2 (Nrf2) signaling cascade. These protective effects were not observed with the other treatments. These results suggest that a combination of component herbs in HLJDD exhibit stronger effects than the individual herbs alone. Our integrated metabolomics approach also provides a tractable, powerful tool for understanding the science behind TCM formulations. PMID:27779107

    Belzile, Melany

    Le fjord du Saguenay, localise dans la region subarctique de l'est du Canada, ala particularite d' etre connecte a un estuaire tres energetique plutot que directement a 1' ocean. L'embouchure du fjord est situee ala rencontre d'un chenal profond et d'un seuil de 20m de profondeur qui limite les echanges d'eau entre le fjord et l'estuaire du Saint-Laurent. Cependant, les grandes amplitudes de maree a son embouchure ont le potentiel d'entrainer des eaux denses du Saint-Laurent a l'interieur du fjord renouvelant ainsi les eaux des differents bassins. Dans le but d' a voir une meilleure comprehension de la dynamique et de la saisonnalite des renouvellements dans le bassin interne, deux mouillages y ont ete deployes pour recolter les premieres donnees de courant, sur toute la colonne d' eau et sur plusieurs mois, ainsi que des observations de temperature et de salinite a differentes profondeurs. L'un de ces mouillages n' a malheureusement pas pu etre analyse en detail dfi a la complexite de ses resultats et au manque de temps. Des profils ont ete recoltes le long de section transversales (transects), couvrant plusieurs saisons et plusieurs annees, ce qui a contribue a une meilleure comprehension de la distribution spatiale des masses d'eau dans le fjord. Les resultats montrent que ladynamique du fjord est plus complexe que ce qui avait ete precedemment presente dans la litterature. Un changement saisonnier abrupte dans la circulation du fjord a ete observe a la rni-fevrier. De plus, des renouvellements non-anticipes juste en-dessous de la thermohalocline (˜ 10 m de profondeur) ont ete observes entre la fin de 1' hiver et le milieu de 1' ete. En fonction des saisons, trois types de renouvellement peuvent etre observes : renouvellements profonds a l'automne et au debut de l'hiver suivis des renouvellements de sous-surface et enfin les renouvellements a des profondeurs intermediaires pendant l'ete. Le changement saisonnier abrupte observe au milieu de l'hiver ainsi que la

    2006-01-01

    The Cri du Chat syndrome (CdCS) is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-). The incidence ranges from 1:15,000 to 1:50,000 live-born infants. The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: cardiac, neurological and renal abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism. Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement. Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Two genes, Semaphorin F (SEMAF) and δ-catenin (CTNND2), which have been mapped to the "critical regions", are potentially involved in cerebral development and their deletion may be associated with mental retardation in CdCS patients. Deletion of the telomerase reverse transcriptase (hTERT) gene, localised to 5p15.33, could contribute to the phenotypic changes in CdCS. The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction (PCR) and three candidate genes were characterised in this region. The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis.

    1996-08-07

    Scientists at DuPont say they have demonstrated the first chemical processing application for high-temperature superconducting (HTS) magnets. DuPont says the work, which uses a HTS magnet to separate mineral contaminants from kaolin, points to the feasibility of a range of HTS applications in industrial processing, including those involving polymerization. DuPont`s success comes after 10 years of work to commercialize high-temperature superconductors. And while superconductors have lost much of their luster since the late 1980s, the company says it is still bullish on their prospects. {open_quotes}At the moment, there`s no real market for superconductors,{close_quotes} says Alan Lauder, general manager/superconductivity. But, he says, several potentially lucrative applications could be commercialized within the next several years.

    Butanediol (BDO) and its derivatives continue to be strong, a positive sign for the many companies planning expansions. DuPont - one of only two global producers not planning capacity additions - has announced that it will discontinue all off-schedule pricing for BDO and two important derivatives, tetrahydrofuran (THF) and polytetramethylene ether glycol (PTMEG). DuPont`s list prices are $1.00/lb fob for BDO, about $1.40/lb for THF, and $2.00/lb for PTMEG. The price adjustment is effective this month or as contracts allow.

    Le puisatier a pour profession le creusement et l'entretien des puits pour fournir de l'eau. Il est au contact de divers minerais, particulièrement la silice, particule qui présente un risque certain de développement des maladies pulmonaires connues sous le nom de silicose. Le but de notre travail est de préciser le profil épidémiologique, clinique, radiologique et évolutif des patients puisatiers silicotiques. C'est une étude rétrospective concernant 54 cas de puisatiers ayant une silicose, colligés au service des maladies respiratoires du CHU Ibn Rochd de Casablanca, de Mars 1997 à Janvier 2016. Tous les malades étaient des puisatiers, de sexe masculin, avec une moyenne d'âge de 50 ans. Le tabagisme était retrouvé dans 36 cas et un antécédent de tuberculose était noté dans huit cas. La radiographie thoracique retrouvait des grandes opacités dans 39 cas, des petites opacités dans 15 cas, et un épaississement des septats dans 11 cas. Ce tableau de silicose s'était compliqué d'une surinfection bactérienne dans 37% des cas, d' un pneumothorax dans 4% des cas et d'une tuberculose dans 20% des cas. La prise en charge thérapeutique était celle des complications. La déclaration de la maladie professionnelle et de l'indemnisation était faite. L'évolution était bonne dans 12 cas, stationnaire dans 17 cas et mauvaise dans 16 cas. La silicose est une pneumoconiose fréquente chez les puisatiers. Elle retentit sur la fonction respiratoire. Nous soulignons l'association fréquente de tuberculose et nous insistons sur la prévention qui reste le meilleur traitement. PMID:28292119

    Le cancer du sein est le cancer le plus fréquent chez la femme, notamment au Maroc, avec un taux de mortalité élevé. Les métastases gastro-intestinales d'un carcinome canalaire du sein sont rares. Leur diagnostic est difficile du fait de la nature non spécifique des symptômes. Nous rapportons deux observations originales de métastases gastroduodénales d'un cancer canalaire infiltrant du sein. Les métastases gastro-intestinales du cancer du sein sont très rares; la présence de symptômes gastro-intestinaux chez une malade ayant un antécédent de cancer du sein doit faire suspecter une atteinte métastatique gastro-intestinale.

    Résumé Objectif Se pencher sur les critères diagnostiques du trouble du spectre de l’autisme (TSA) comme les définit le Manuel diagnostique et statistique des troubles mentaux, cinquième édition (DSM-V), et concevoir une approche de prise en charge du TSA à l’aide du cadre CanMEDS–Médecine familiale (CanMEDS-MF). Sources d’information Le DSM-V, publié par l’American Psychiatric Association en mai 2013, énonce de nouveaux critères diagnostiques du TSA. Le cadre CanMEDS-MF du Collège des médecins de famille du Canada fournit un plan d’orientation pour la prise en charge complexe du TSA. Nous avons utilisé des données recueillies par le Centers for Disease Control and Prevention afin de déterminer la prévalence du TSA, ainsi que la revue systématique et méta-analyse détaillée effectuée par le National Institute for Health and Care Excellence du R.-U. pour ses lignes directrices sur le TSA dans le but d’évaluer les données probantes issues de plus de 100 interventions. Message principal Selon les données du Centers for Disease Control and Prevention, la prévalence du TSA se chiffrait à 1 sur 88 en 2008 aux États-Unis. La classification du TSA dans la quatrième édition du DSM incluait l’autisme, le syndrome d’Asperger, le trouble envahissant du développement et le trouble désintégratif de l’enfance. La dernière révision du DSM-V réunit tous ces troubles sous la mention TSA, avec différents niveaux de sévérité. La prise en charge du TSA est complexe; elle exige les efforts d’une équipe multidisciplinaire ainsi que des soins continus. Les rôles CanMEDS-MF fournissent un cadre de prise en charge. Conclusion Les médecins de famille sont au cœur de l’équipe de soins multidisciplinaire pour le TSA, et le cadre CanMEDS-MF tient lieu de plan détaillé pour guider la prise en charge d’un enfant atteint de TSA et aider la famille de cet enfant.

    Les plaies du tendon patellaire sont peu fréquentes et sont peu rapportés dans la littérature, contrairement aux ruptures sous cutanées. Les sections du tendon patellaire nécessitent une réparation immédiate afin de rétablir l'appareil extenseur et de permettre une récupération fonctionnelle précoce. A travers ce travail rétrospectif sur 13 cas, nous analysons les aspects épidémiologiques, thérapeutiques et pronostiques de ce type de pathologie en comparant différents scores. L’âge moyen est de 25 ans avec une prédominance masculine. Les étiologies sont dominées par les accidents de la voie publique (68%) et les agressions par agent tranchant (26%) et contendant (6 %). Tous nos patients ont bénéficié d'un parage chirurgical avec suture tendineuse direct protégée par un laçage au fils d'aciers en légère flexion. La rééducation est débutée après sédation des phénomènes inflammatoires. Au dernier recul les résultats sont excellents et bon à 92%. Nous n'avons pas noté de différence de force musculaire et d'amplitude articulaire entre le genou sain et le genou lésé. Les lésions ouvertes du tendon patellaire est relativement rare. La prise en charge chirurgicale rapide donne des résultats assez satisfaisants. La réparation est généralement renforcée par un semi-tendineux, synthétique ou métallique en forme de cadre de renfort pour faciliter la réadaptation et réduire le risque de récidive après la fin de l'immobilisation.

  20. Biokinetics and dosimetry of depleted uranium (DU) in rats implanted with DU fragments.

    2004-01-01

    A number of U. S. veterans of the Persian Gulf War were wounded with depleted uranium (DU) metal fragments as a result of 'friendly fire' incidents, in which Abrams tanks and Bradley fighting vehicles were struck by DU anti-armor munitions. Some of the crew members who survived were left with multiple small fragments of DU in their muscles and soft tissues. The number, size and location of the fragments made them inoperable in general, and therefore subject to long-term retention. Because there was inadequate data to predict the potential carcinogenicity of DU fragments in soft tissues, Hahn et al. (2003) conducted a lifespan cancer study in rats. As part of that study, a number of rats were maintained to study the biokinetics and dosimetry of DU implanted intramuscularly in male Wistar rats. Typically, four metal fragments, either as cylindrical pellets or square wafers were implanted into the biceps femoris muscles of the rats. Urine samples were collected periodically during their lifespans, and DU was analyzed in kidneys and eviscerated carcass (minus the implant sites) at death. The daily DU urinary excretion rate increased steeply during the first 30 d after implantation peaking at about 90 d at 3-10 x 10{sup -3}%/d. During the first 150 d, the average excretion rate was 2.4 x 10{sup -3}%/d, decreasing thereafter to about 1 x 10{sup -3}%/d. Serial radiographs were made of the wound sites to monitor gross morphologic changes in the DU implant and the surrounding tissue. As early as 1 w after implantation, radiographs showed the presence of surface corrosion and small, dense bodies near the original implant, presumably DU. This corrosion from the surface of the implant continued with time, but did not result in an increasing amount of DU reaching the blood and urine after the first 3 mo. During this 3-mo period, connective tissue capsules formed around the implants, and are hypothesized to have reduced the access of DU to tissue fluids by limiting the diffusion

    Abstract Objective To present Cirque du Soleil’s social circus program, Cirque du Monde, to explore its potential as a primary health care tool for family physicians. Data sources A review of the literature in PubMed, the Cochrane Library, PsycINFO, LaPresse, Eureka, Google Scholar, and Érudit using the key words circus, social circus, Cirque du Monde, and Cirque du Soleil; a Montreal-based initiative, Espace Transition, modeled on Cirque du Monde; and personal communication with Cirque du Soleil’s Social Circus Training Advisor. Study selection The first 50 articles or websites identified for each key word in each of the databases were examined on the basis of their titles and abstracts in the case of articles, and on the basis of their titles and page content in the case of websites. Articles and websites that explored an aspect of social circuses or that described an intervention that involved circuses were then retained for analysis. Because all literature on social circuses was searched, no criterion for year of publication was used. Synthesis No articles on the social circus as a health intervention were found. One study on the use of the circus as an intervention in schools was identified. It demonstrated an increase in self-esteem in the children who took part. One study on the use of the circus in a First Nations community was found; it contained nonspecific, qualitative findings. The other articles identified were merely descriptions of social circuses. One website was identified on the use of the social circus to help youth who had been treated in a hospital setting for major psychiatric disorders to re-enter the community. The team in the pediatric psychiatry department at Centre Hospitalier Universitaire Sainte-Justine, the children’s hospital in Montreal, Que, was contacted; they were leading this project, called Espace Transition. The unpublished preliminary findings of its pilot project demonstrate substantial improvements in overall patient

    Non-metastatic glycoprotein melanoma protein B (GPNMB), also known as osteoactivin (OA) is expressed in a wide array of tumors and represents an emerging target for drug development. In this study, we investigated the role of GPNMB/OA in the progression of human metastatic DU145 and PC3 prostate cancer cells. GPNMB/OA contribution in PCa malignant phenotype has been analyzed by small interfering RNA-induced GPNMB/OA silencing. We found that following GPNMB/OA silencing the migration capability of both DU145 and PC3 cells, evaluated by using in vitro invasivity assay, as well as the metalloproteinases MMP-2 and MMP-9 activity were equally strongly inhibited. By contrast knocking down GPNMB/OA weakly attenuated cell proliferation rate of DU145, an effect that paralleled with an increase number of apoptotic cells. However, PC3 cell growth seems to be not affected by GPNMB/OA. Together, these data reveal that GPNMB/OA acts as a critical molecular mediator promoting the acquisition of the more aggressive, pro-metastatic phenotype distinctive of human DU145 and PC3 cell lines. - Highlights: • GPNMB/OA expression correlates with DU145 and PC3 cells malignant phenotype. • GPNMB/OA silencing affects the migration capability of both DU145 and PC3 cells. • GPNMB/OA increases invasiveness by up-regulating MMPs activity. • GPNMB/OA promotes DU145 and PC3 cells progression into a more aggressive phenotype.

    Since Lejeune et al. (1963) first described the syndrome of Cri du Chat (Cry of the Cat), cases have been described in the literature in terms of genetic abnormalities. All cases were severely retarded and the mental impairment has been believed to be progressive, although no longitudinal studies have been reported. Descriptions of speech and language behavior have been scarce. This paper presents a case of a 7-yr, 6 mo-old girl with Cri du Chat who has received speech and language therapy for five years. Her speech, language, and mental development are noted and are not consistent with cases reported previously.

    Southeast Community College (SCC) hosted the first DuPont Conference for Chemical Technology Education at its Lincoln, Nebraska campus October 4-6, 1997. The conference brought together fourteen practicing chemists and chemistry technicians and five college and university faculty members for the express purpose of suggesting new laboratory activities that would help relate the real world of work to the education of chemical laboratory technicians in community colleges. Participants included seven men and seven women from DuPont, Procter & Gamble, Eastman Chemical, Eastman Kodak, Dow Chemical, Air Products and Chemicals, Monsanto, Union Carbide, the Nebraska Agriculture Laboratory, and the University of Nebraska Biological Process Development Facility, Department of Food Science. The conference, sponsored by the E. I. DuPont DeNemours & Company through a grant awarded to SCC in June 1997, was intended to help further the goals of the two major projects underway at SCC, funded by the National Science Foundation's Advanced Technological Education Program. These projects, dubbed "Assignment: Chemical Technology I and II", or ACT-I and ACT-II, are curriculum and materials development projects. The invited scientists had between 2 and 32 years of experience that ranged from bench work to management levels. Many are or have been active on the national scene as members and officers of the American Chemical Society's Division of Chemical Technicians and the ACS Committee on Technician Activities.

    The Idaho National Engineering Laboratory (INEL) is developing new methods to produce high-density aggregate (artificial rock) primarily consisting of depleted uranium oxide. The objective is to develop a low-cost method whereby uranium oxide powder (UO[sub 2], U[sub 3]O[sub ]8, or UO[sub 3]) can be processed to produce high-density aggregate pieces (DU-AGG) having physical properties suitable for disposal in low-level radioactive disposal facilities or for use as a component of high-density concrete used as shielding for radioactive materials. A commercial company, G-M Systems, conducted a design study for a manufacturing pilot plant to process DU-AGG. The results of that study are included and summarized in this report. Also explained are design considerations, equipment capacities, the equipment list, system operation, layout of equipment in the plant, cost estimates, and the proposed plan and schedule.

  1. Sustainable growth, the DuPont way.

    PubMed

    Holliday, C

    2001-09-01

    Like many manufacturers, DuPont traditionally has grown by making more and more "stuff." And its business growth has been proportional to the amount of raw materials and energy used--as well as the resulting waste and emissions from operations. Over the years, though, DuPont became aware that cheap supplies of nonrenewable resources wouldn't be endlessly available and that the earth's ecosystems couldn't indefinitely absorb the waste and emissions of production and consumption. Chad Holliday, chairman and CEO of DuPont, believes strongly in the challenge of sustainable growth and makes the business case for it: By using creativity and scientific knowledge effectively, he says, companies can provide strong returns for shareholders and grow their businesses--while also meeting the human needs of societies around the world and reducing the environmental footprint of their operations and products. In fact, a focus on sustainability can help identify new products, markets, partnerships, and intellectual property and lead to substantial business growth. Holliday describes how DuPont developed a three-pronged strategy to translate the concept of sustainability into nuts-and-bolts business practices. Focusing on integrated science, knowledge intensity, and productivity improvement, the strategy was accompanied by a new way to measure progress quantitatively. Sustainable growth should be viewed not as a program for stepped-up environmental performance but as a comprehensive way of doing business, one that delivers tremendous economic value and opens up new opportunities. Ultimately, companies will find that they can generate substantial business value through sustainability while both enhancing the quality of life around the world and protecting the environment.

    DuPont Safety Resources was tasked with reviewing the current chemical vapor control practices and providing preventive recommendations on best commercial techniques to control worker exposures. The increased focus of the tank closure project to meet the 2024 Tri-Party Agreement (TPA) milestones has surfaced concerns among some CH2MHill employees and other interested parties. CH2MHill is committed to providing a safe working environment for employees and desires to safely manage the tank farm operations using appropriate control measures. To address worker concerns, CH2MHill has chartered a ''Chemical Vapors Project'' to integrate the activities of multiple CH2MHill project teams, and solicit the expertise of external resources, including an independent Industrial Hygiene expert panel, a communications consultant, and DuPont Safety Resources. Over a three-month time period, DuPont worked with CH2MHill ESH&Q, Industrial Hygiene, Engineering, and the independent expert panel to perform the assessment. The process included overview presentations, formal interviews, informal discussions, documentation review, and literature review. DuPont Safety Resources concluded that it is highly unlikely that workers in the tank farms are exposed to chemicals above established standards. Additionally, the conventional and radiological chemistry is understood, the inherent chemical hazards are known, and the risk associated with chemical vapor exposure is properly managed. The assessment highlighted management's commitment to addressing chemical vapor hazards and controlling the associated risks. Additionally, we found the Industrial Hygiene staff to be technically competent and well motivated. The tank characterization data resides in a comprehensive database containing the tank chemical compositions and relevant airborne concentrations.

    Le rutile est un oxyde metallique qui presente beaucoup de similitudes avec certains perovskites notamment le titanate de barium ou de strontium. Il est comme ces derniers, compose d'un agencement d'octaedres d'oxygene centres sur l'atome de titane. Ces octaedres sont responsables de la forte polarisabilite de ces cristaux et de leur grande constante dielectrique. Leurs proprietes optiques, seuil d'absorption et spectre de phonons, sont par exemple forts semblables. La presente etude vise a determiner la nature du transport electronique dans le rutile stoechiometrique pur et d'en comparer les resultats avec les proprietes de certains perovskites. Nous determinerons par differentes mesures optoelectroniques les parametres caracteristiques des pieges et leur influence sur le transport des electrons et des trous. Les resultats de conductivite et de capacitance de meme que les spectres de photoconductivite dans nos echantillons ont mis en evidence la presence d'au moins cinq niveaux energetiques dans la bande interdite du rutile agissant comme pieges pour les electrons ou pour les trous et qui jouent un role de premiere importance dans le comportement electrique du rutile. Par la technique de charge transitoire, nous determinerons pour la premiere fois dans le rutile stoechiometrique la grandeur de la mobilite de derive des trous a la temperature ambiante soit 3,4 cm^2/V cdots et nous etablierons une borne superieure a la mobilite des electrons soit 0,1 cm^2 /Vcdots.

    La connaissance des proprietes et du comportement d'un materiau en usinage est primordiale pour optimiser son utilisation et obtenir une usinabilite maximale. Dans ce but, l'etude de la modification de la ductilite par traitement thermiques sur plusieurs criteres d'usinabilite tels que les efforts de coupe, la rugosite, les bavures et la formation du copeau a ete menee sur le laiton monophase. A cette fin, l'influence du traitement thermique sur la microstructure du laiton a d'abord ete etudiee. La taille des grains et la durete ont permis de determiner les proprietes mecaniques des etats metallurgiques. Des essais de percage ont ensuite ete effectues sur les etats metallurgiques H01 (99HV), OS100 (88HV) et OS250 (47HV) pour regarder l'influence du traitement thermique sur l'usinabilite. Cette etude experimentale a permis de comprendre l'influence du taux de laminage et de la temperature de recuit sur les proprietes mecaniques. Les essais d'usinabilite ont ensuite permis de prouver que les efforts de coupe sont dependants des conditions de coupe mais pas de la ductilite dans les etats metallurgiques testes. La taille des bavures augmente avec la ductilite et la vitesse de coupe, et diminue avec l'avance. La rugosite de la surface des trous apres l'usinage a egalement ete etudiee. Il a aussi ete prouve par une etude sur les copeaux que la temperature croit avec la vitesse de coupe. L'analyse de la segmentation des copeaux n'a en revanche pas permis de trouver une correlation significative avec les traitements thermiques testes. Enfin, le revetement de l'outil a montre une grande importance sur l'usinabilite du materiau. Il a ete conclu que l'usinabilite du laiton C26000 (CuZn30) est meilleure lorsqu'on travaille dans un etat metallurgique dur. Ces conclusions sont valables pour le laiton monophase etudie, il serait interessant d'examiner aussi le cas des laitons biphases.

    Les sourcils jouent un rôle important dans l’équilibre esthétique du visage. Leur reconstruction ou ophriopoïése, après séquelle de brûlure fait partie intégrante du programme de réhabilitation de la face brûlée. Plusieurs techniques ont été décrites. Nous insistons ici sur l'intérêt d'une technique simple, à la portée de tous les chirurgiens, et dont la méthode et les résultats peuvent être améliorés par un dessin bien planifié des zones donneuse et receveuse: la greffe composite prélevée au niveau du cuir chevelu dessinée à l'aide d'un calque du sourcil controlatéral.

    Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

  18. Modelisation par elements finis du muscle strie

    NASA Astrophysics Data System (ADS)

    Leonard, Mathieu

    Ce present projet de recherche a permis. de creer un modele par elements finis du muscle strie humain dans le but d'etudier les mecanismes engendrant les lesions musculaires traumatiques. Ce modele constitue une plate-forme numerique capable de discerner l'influence des proprietes mecaniques des fascias et de la cellule musculaire sur le comportement dynamique du muscle lors d'une contraction excentrique, notamment le module de Young et le module de cisaillement de la couche de tissu conjonctif, l'orientation des fibres de collagene de cette membrane et le coefficient de poisson du muscle. La caracterisation experimentale in vitro de ces parametres pour des vitesses de deformation elevees a partir de muscles stries humains actifs est essentielle pour l'etude de lesions musculaires traumatiques. Le modele numerique developpe est capable de modeliser la contraction musculaire comme une transition de phase de la cellule musculaire par un changement de raideur et de volume a l'aide des lois de comportement de materiau predefinies dans le logiciel LS-DYNA (v971, Livermore Software Technology Corporation, Livermore, CA, USA). Le present projet de recherche introduit donc un phenomene physiologique qui pourrait expliquer des blessures musculaires courantes (crampes, courbatures, claquages, etc.), mais aussi des maladies ou desordres touchant le tissu conjonctif comme les collagenoses et la dystrophie musculaire. La predominance de blessures musculaires lors de contractions excentriques est egalement exposee. Le modele developpe dans ce projet de recherche met ainsi a l'avant-scene le concept de transition de phase ouvrant la porte au developpement de nouvelles technologies pour l'activation musculaire chez les personnes atteintes de paraplegie ou de muscles artificiels compacts pour l'elaboration de protheses ou d'exosquelettes.

    Le cancer du sein est actuellement le cancer le plus fréquent chez la femme, et pose un véritable problème diagnostique et thérapeutique. Le dépistage des lésions à un stade de plus en plus précoce, a permis une extension des indications du traitement conservateur radiochirurgical, qui était initialement limitées aux tumeurs de moins de 3 cm, unifocales, non inflammatoires. Par ailleurs, l'utilisation de traitements préopératoires permet d’étendre les indications du traitement conservateur à des tumeurs plus volumineuses. Parallèlement à cette extension des indications de conservation mammaire, on a observé le développement de nouvelles approches thérapeutiques notamment la chirurgie oncoplastique, technique du ganglion sentinelle et chirurgie stéréotaxique, dont les résultats initiaux sont très encouragent. A travers cette étude réalisée dans le service de gynécologie et obstétrique II du CHU HASSAN II de FES au MAROC, après l'analyse rétrospective de 16 patientes traitées par traitement conservateur et oncoplastie, nous avons voulus montrer notre aptitude a réalisé ses techniques chirurgicales et a bien prendre en charge ces patientes, mais aussi évaluer ces techniques en termes de résultat carcinologique et de résultat esthétique, aussi en terme de survie globale, survie sans métastase et en termes de récidive locale entre les plasties mammaires et les traitements usuels: mastectomie et traitement conservateur classique.

    Résumé Objectif Présenter une mise à jour sur l’utilité clinique de ne pas être à jeun par rapport à l’être pour l’analyse des lipides dans le but d’améliorer l’observance par les patients, leur sécurité et l’évaluation clinique dans les tests du cholestérol. Qualité des données Les recommandations sont classées comme étant fondées sur des données probantes fortes, acceptables ou faibles (conflictuelles ou insuffisantes), selon les classifications adoptées par le Groupe d’étude canadien sur les soins de santé préventifs. Message principal Le dépistage de la dyslipidémie comme facteur de risque de coronaropathie et la prescription de médicaments hypolipidémiants sont des activités importantes en soins primaires. De récentes données probantes remettent en question la nécessité d’être à jeun pour la mesure des lipides. Dans des études sur la population, le cholestérol total, le cholestérol à lipoprotéines de haute densité et le cholestérol à lipoprotéines autres qu’à haute densité variaient tous d’en moyenne 2 % à jeun. Pour un dépistage de routine, la mesure du cholestérol sans être à jeun est maintenant une option de rechange raisonnable à l’analyse à jeun. Pour les patients diabétiques, l’exigence d’être à jeun peut représenter un important problème de sécurité en raison des possibilités d’hypoglycémie. Pour la surveillance des triglycérides et du cholestérol à lipoprotéines de basse densité chez les patients qui prennent des médicaments hypolipidémiants, le jeûne devient important. Conclusion Être à jeun pour la détermination routinière des niveaux lipidiques est largement inutile et il est improbable que le jeûne influence la stratification du risque clinique chez le patient, tandis que la mesure sans être à jeun pourrait améliorer l’observance par le patient et sa sécurité.

  2. Act resilient.

    2014-01-01

    Attendees have reported changing from being fearful to serene, from listless to energized, from disengaged to connected, and becoming markedly less anxious in a few weeks. Anecdotally, self-reported stress levels have been reduced by over 50% after just one class. Attendees learn not to be afraid of their feelings by working with emotions in a playful manner. When a person can act angry, but separate himself from his personal story, the emotional energy exists in a separate form that is not attached to specific events, and can be more easily dealt with and neutralized. Attendees are taught to "take out the emotional trash" through expressive comedy. They become less intimated by their own emotional intensity and triggers as they learn how even metaphorical buckets of anger, shame, guilt and hurt can be emotionally emptied. The added benefit is that this is accomplished without the disclosure of personal information of the requirement to reexperience past pain which can trigger its own cascade of stress.

  4. Mesure du taux de la capture radiative du muon par l'hydrogene liquide

    NASA Astrophysics Data System (ADS)

    Jonkmans, Guy

    À basse énergie, l'interaction faible entre leptons et quarks est décrite par une interaction de la forme courant × courant de type V - A. La présence de l'interaction forte induit des couplages additionnels qui doivent être déterminés expérimentalement. De ceux-ci, le couplage pseudoscalaire induit, gp , est mesuré avec la plus grande incertitude et fait l'objet de la présente recherche. L'hypothèse du Courant Axial Partiellement Conservé (CAPC) et l'usage de la relation de Goldberger-Treiman relie gp au couplage axial ga . Cette relation a été vérifiée traditionnellement par la Capture Ordinaire du Muon (COM) à une valeur fixe du moment de transfert q. La Capture Radiative du Muon (CRM), m- p-->nnmg , est un meilleur outil pour l'étude de gp à cause de sa dépendance variable en q2 qui offre une plus grande sensibilité dans la partie à haute énergie du spectre des photons. Toutefois, le petit rapport d'embranchement (~10-8) de la CRM par rapport à la désintégration du muon a retardé cette mesure jusqu'à ce jour. La théorie et les difficultés expérimentales associées à la détection des photons de CRM sont présentées au deuxième chapitre. On décrit ensuite, au troisième chapitre, les composantes du système de détection. Ce détecteur est un spectromètre à paires de grand angle solide (~3p) et qui permet l'observation des photons par l'analyse des électrons et des positrons de photo-conversion. Ainsi, le bruit de fond important des neutrons de la COM ne constitue pas un problème pour cette mesure. Nous décrivons, au quatrième chapitre, toutes les étapes de l'analyse, nécessaires pour la réduction des multiples bruits de fond. Le cinquième chapitre présente le calcul des efficacités ainsi que l'estimation des erreurs systématiques. Le sixième chapitre démontre comment l'on extrait le rapport d'embranchement pour la CRM ainsi que la valeur ae gp . On insiste sur la dépendance de gp en fonction de la valeur de

  5. A novel synthetic protoapigenone analogue, WYC02-9, induces DNA damage and apoptosis in DU145 prostate cancer cells through generation of reactive oxygen species.

    The protoapigenone analogue WYC02-9, a novel synthetic flavonoid, has been shown to act against a variety of experimental tumors. However, its effects on prostate cancer and its mechanism of action are unknown. Thus, WYC02-9 was investigated for its cytotoxicity against DU145 prostate cancer cells, as was the underlying mechanisms by which WYC02-9 might induce DNA damage and apoptotic cell death through reactive oxygen species (ROS). WYC02-9 inhibited the cell growth of three prostate cancer cell lines, especially DU145 cells. In DU145 cells, WYC02-9 increased the generation of intracellular ROS, followed by induction of DNA damage and activation of the ATM-p53-H2A.X pathway and checkpoint-related signals Chk1/Chk2, which led to increased numbers of cells in the S and G2/M phases of the cell cycle. Furthermore, WYC02-9 induced apoptotic cell death through mitochondrial membrane potential decrease and activation of caspase-9, caspase-3, and PARP. The above effects were all prevented by the ROS scavenger N-acetylcysteine. Administration of WYC02-9 in a nude mouse DU145 xenograft model further identified the anti-cancer activity of WYC02-9. These findings therefore suggest that WYC02-9-induced DNA damage and mitochondria-dependent cell apoptosis in DU145 cells are mediated via ROS generation.

  6. The Pic du Midi solar survey

    2015-12-01

    We carry a long term survey of the solar activity with our coronagraphic system at Pic du Midi de Bigorre in the French Pyrenees (CLIMSO). It is a set of two solar telescopes and two coronagraphs, taking one frame per minute for each of the four channels : Solar disk in H-α (656.28 nm), prominences in H-α, disk in Ca II (393.3 nm), prominences in He I (1083 nm), all year long, weather permitting. Since 2015 we also take images of the FeXIII corona (1074.7 nm) at the rate of one every 10 minutes. These images cover a large field: 1.25 solar diameter, 2k*2K pixels, and are freely downloadable form a database. The improvements made since 2015 concern an autoguiding system for better centering of the solar disk behind the coronagraphic masks, and a new Fe XIII channel at λ=1074.7 nm. In the near future we plan to provide radial velocity maps of the disc and polarimetry maps of the disk and corona. This survey took its present form in 2007 and we plan to maintain image acquisition in the same or better experimental conditions for a long period: one or several solar cycles if possible. During the partial solar eclipse of March 20, 2015, the CLIMSO instruments and the staff at Pic du Midi operating it have provided several millions internet users with real time images of the Sun and Moon during all the phenomenon.

    Recent cave biodiversity surveys carried out in Du'an County and its adjacent areas of northwestern Guangxi, China, have revealed some exciting scientific findings. In a very limited area seven new species of the cavernicolous trechine genus Dongodytes Deuve, 1993 were found and are described: Dongodytes(s. str.)elongatussp. n., Dongodytes(s. str.)troglodytessp. n., Dongodytes(s. str.)lanisp. n., Dongodytes (Dongodytodes) brevipenissp. n., Dongodytes (Dongodytodes) jinzhuensissp. n., Dongodytes (Dongodytodes) inexpectatussp. n. and Dongodytes (Dongodytodes) yaophilussp. n. Diagnoses and notes on the genus, subgenera, and two known species in Du'an Karst, Dongodytes(s. str.)baxian Tian, 2011 and Dongodytes (Dongodytodes) deharvengi Tian, 2011, are also given. A key to subgenera and all species of Dongodytes is provided. To date, Dongodytes becomes one of the richest in species genera of subterranean carabid trechines in China with 12 species which are arranged into two subgenera. Dongodytes (s. str.) Deuve is composed of seven species, four of which from Du'an County, each of other three from Bama, Fengshan and Tian'e Counties, respectively. All species of the subgenus Dongodytodes Tian, 2011 are recorded from Du'an Karst. By having 10 species (nine Dongodytes and one Libotrechus Uéno, 1998), Du'an Karst holds the richest specific diversity of cavernicolous Trechinae in China. Dongodytes species are distributed in a very limited area of the river Hongshui He drainages in northwestern Guangxi, and the river acts as a natural barrier of Dongodytes dispersal at only a specific level. However, all members of Dongodytodes are recorded from the eastern or northern bank of Hongshui He.

    The aqueous extract of Psidium guajava L. (PE) inhibited the cancer cell DU-145 in a dose- and time-dependent manner. At 1.0 mg/mL, PE reduced the viability of PCa DU-145 (the androgen independent PCa cells) to 36.1 and 3.59%, respectively after 48 h and 72 h of incubations. The absolute cell viability suppressing capability (VSC)(AC) could reach 262.5 cells-mL-h/mg on exposure to PE for 72 h, corresponding to the safe ranges, i.e. the percent viability suppressing rates (PVSR) of 2.72 and 2.41 folds for DU-145 comparing to PZ-HPV-7 cells when treated with PE at 0.5 and 1.0 mg/mL respectively for 72 h. In addition, the colony forming capability of DU-145 cells was apparently lowered. The suppressing rates of which reached 8.09 and 5.96 colony/mg/day for D-145 and PZ-HPV-7 cells, respectively within the concentration range of PE at 0.1 asymptotically equal to 0.25 mg/mL. Cell cycle arrests at G0/G1 phase in both cells were observed by TUNEL assay and flow cytometric analysis, yet more prominently evident in DU-145. In addition, suppression of the matrix metalloproteinases MMP-2 and MMP-9, and the upregulation of active caspase-3 at 0.10 to 1.0 mg/mL in DU-145 were also effected in a dose-dependent manner by PE at 0.25 to 1.0 mg/mL, implicating a potent anti-metastasis power of PE. Conclusively, we ascribe the anticancer activity of PE to its extraordinarily high polyphenolic (165.61 +/- 10.39 mg/g) and flavonoid (82.85 +/- 0.22 mg/g) contents. Furthermore, PE might be useful for treatment of brain derived metastatic cancers such as DU-145, acting simultaneously as both a chemopreventive and a chemotherapeutic.

  9. Establishment of the DU.528 human lymphohemopoietic stem cell line

    PubMed Central

    1985-01-01

    We have established the DU.528 cell line from the pretreatment leukemia cells of a patient who underwent a T lymphoblastic-to-promyelocytic phenotype conversion during treatment with the adenosine deaminase inhibitor, deoxycoformycin. The cell line and clones obtained from it by limiting dilution have the same karyotype previously found in the patient's pretreatment T lymphoblasts and post-deoxycoformycin treatment promyelocytes. DU.528 cells in continuous culture for greater than 2 yr display a predominant undifferentiated T lymphoblastoid phenotype. These cells spontaneously generate progeny of at least three lineages, T lymphoid, granulocytic/monocytic, and erythroid. The surface marker most consistently expressed by DU.528 cells in the undifferentiated state is the 3A1 antigen, which has been found on prothymocytes in the embryonic thymus. Some undifferentiated DU.528 cells also expressed the IL-2 receptor, but no other T cell differentiation antigens. Exposure of DU.528 cells to a variety of agents induced myeloid maturation; adenosine and deoxyadenosine, in the presence of deoxycoformycin, induced expression of myeloid differentiation antigens. Our results suggest that DU.528 is a lymphohematopoietic stem cell line and support the hypothesis that differentiation of pluripotent stem cells may be altered by genetic deficiency of adenosine deaminase. DU.528 cells may provide a useful model for examining factors that regulate stem cell proliferation and differentiation. PMID:4056659

We suggest that Cri-du-Chat syndrome chould be suspected in children with brain stem hypoplasia, particularly for those with high-pitched cries. PMID:24265573

    Developmental and behavioural characteristics were assessed in 27 children with cri du chat syndrome using the Society for the Study of Behavioural Phenotypes questionnaire, which gave information on prenatal and perinatal conditions, neurological problems, and developmental and behavioural difficulties. The findings suggest that the behavioural profile of children with cri du chat syndrome incorporates self injurious behaviour, repetitive movements, hypersensitivity to sound, clumsiness, and obsessive attachments to objects. In terms of a developmental profile, children with cri du chat syndrome were able to communicate their needs, socially interact with others, and have some degree of mobility. PMID:8957962

  14. Depleted uranium (DU): a holistic consideration of DU and related matters.

    Following the use of depleted uranium (DU) during the Gulf and Balkan conflicts, unnecessary and costly confusion has existed for some 11 years concerning the hazard it constitutes, despite the fact that sufficient data are available to answer most of the relevant questions. In tracing the significance of uranium in the environment and humans, too much reliance is still placed upon the extrapolation of animal data. The existing radiological nomenclature is far too involved and complex to understand, let alone implement. The excellence of early health physics seems to have been lost, and hence there is a failure to utilise the large body of knowledge, and the manner in which it was obtained, in other disciplines. Health physics has failed to understand the nature of some natural processes that ultimately control radiation dose to the environment and humans. Examination of three types of DU, in particular the highly radioactive and potentially hazardous unprocessed, spent-reactor uranium fuel debris (UDU), alluded to as hot particles, has been poorly studied on the basis of scarcity in the environment. Fundamental geological processes are described which illustrate that, as a consequence of routine operation of nuclear reprocessing plants, especially in the past, and following reactor accidents, natural processes can result in an enrichment of DU particles in most types of sediment. Failure to grasp essential geological processes in relation to the dispersion of radionuclides in the environment is detrimental to public acceptance of an essential form of energy in association with others.

    Les fractures luxations du coude sont rares et souvent mal tolérées chez les sujets jeunes actifs. Nous rapportons un cas de fracture-luxation du coude remontant à 20 ans. C'est un jeune de 35 ans, victime il y a 20 ans d'un traumatisme fermé, suite à une chute lors d'un match du football, de son coude gauche occasionnant une fracture-luxation du coude. Le patient a refusé une intervention chirurgicale avec une auto-rééducation. L'examen a mis en évidence une conservation de la fonction du coude. Un bilan radiologique a montré une fracture luxation du coude avec remaniement de la palette humérale. Une abstention thérapeutique a été décidée devant l'ancienneté de la fracture-luxation et la gêne fonctionnelle minime engendrée. Contrairement aux autres séries, la fracture-luxation dans notre cas était bien tolérée malgré le jeune âge du patient. PMID:26113930

    Les variations de la rotation terrestre. En conditionnant à la fois notre vie quotidienne, notre perception du ciel, et bon nombre de phénomènes géophysiques comme la formation des cyclones, la rotation de la Terre se trouve au croisement de plusieurs disciplines. Si le phenomena se faisait uniformément, le sujet serait vite discuté, mais c'est parce que la rotation terrestre varie, même imperceptiblement pour nos sens, dans sa vitesse angulaire comme dans la direction de son axe, qu'elle suscite un grand intérêt. D'abord pour des raisons pratiques : non seulement les aléas de la rotation terrestre modi_ent à la longue les pointés astrométriques à un instant donné de la journée mais in_uencent aussi les mesures opérées par les techniques spatiales ; en consequence l'exploitation de ces mesures, par exemple pour déterminer les orbites des satellites impliqués ou pratiquer le positionnement au sol, nécessite une connaissance précise de ces variations. Plus fondamentalement, elles traduisent les propriétés globales de la Terre comme les processus physiques qui s'y déroulent, si bien qu'en analysant les causes des fluctuations observées, on dispose d'un moyen de mieux connaître notre globe. La découverte progressive des fluctuations de la rotation de la Terre a une longue histoire. Sous l'angle des techniques d'observation, trois époques se pro-celle du pointé astrométrique à l'oeil nu, à l'aide d'instruments en bois ou métalliques (quart de cercle muraux par exemple). À partir du XVIIe siècle débute l'astrométrie télescopique dont les pointés sont complétés par des datations de plus en plus précises grâce à l'invention d'horloges régulées par balancier. Cette deuxième époque se termine vers 1960, avec l'avènement des techniques spatiales : les pointés astrométriques sont délaissés au profit de la mesure ultra-précise de durées ou de fréquences de signaux électromagnétiques, grâce à l'invention des horloges

    An updated summary of a future large astrometric catalogue is presented, based on the two most important astrometric projects carried out by the Real Instituto y Observatorio de la Armada de San Fernando (ROA). The goal is to make a catalogue of positions and proper motions based on ROA's Cart du Ciel (CdC) and the Astrographic Catalogue (AC) San Fernando zone plates, and the HAMC2 meridian circle catalogue. The CdC and AC plates are being reduced together to provide first-epoch positions while HAMC2 will provide second-epoch ones. New techniques have been applied, that range from using a commercial flatbed scanner to the proper reduction schemes to avoid systematics from it. Only thirty plates (out of 540) remain to be processed, due to scanning problems that are being solved.

    Résumé Objectif Présenter aux cliniciens en soins primaires un aperçu pratique et à jour du diagnostic et de la prise en charge du psoriasis. Sources des données Une recension a été effectuée dans les bases de données de PubMed, MEDLINE, EMBASE et Cochrane pour trouver des méta-analyses, des études randomisées contrôlées, des revues systématiques et des études observationnelles pertinentes portant sur le diagnostic et la prise en charge du psoriasis. Message principal Le psoriasis est une maladie inflammatoire chronique et multisystémique qui affecte principalement la peau et les articulations. En plus des dimensions physiques de la maladie, le psoriasis a des répercussions émotionnelles et psychosociales considérables sur les patients, et nuit au fonctionnement social et aux relations interpersonnelles. En tant que maladie inflammatoire systémique, le psoriasis est associé à de multiples comorbidités, dont les maladies cardiovasculaires et les cancers. Le diagnostic est principalement d’ordre clinique et une biopsie de la peau est rarement nécessaire. Selon la sévérité de la maladie, un traitement approprié peut être amorcé. Pour les cas de légers à modérés, le traitement de première intention comporte des thérapies topiques, dont les corticostéroïdes, les analogues de la vitamine D3 et des produits combinés. Ces traitements topiques sont efficaces et peuvent être initiés et prescrits en toute sécurité par des médecins de soins primaires. Les patients dont les symptômes sont plus graves et réfractaires pourraient devoir être envoyés en consultation auprès d’un dermatologue pour une évaluation plus approfondie et une thérapie systémique. Conclusion De nombreux patients atteints de psoriasis consultent leur médecin de soins primaires pour une évaluation initiale et pour recevoir un traitement. La reconnaissance du psoriasis, de même que des comorbidités médicales et psychiatriques qui lui sont associ

    Introduction La classification moléculaire des cancers du sein basée sur l'expression génique puis sur le profil protéique a permis de distinguer cinq groupes moléculaires: luminal A, luminal B, Her2/neu, basal-like et non-classées. L'objectif de cette étude réalisée au CHU Hassan II de Fès est de classer 335 cancers du sein infiltrant en groupes moléculaires, puis de les corréler avec les caractéristiques clinicopathologiques. Méthodes Etude rétrospective étalée sur 45 mois, comportant 335 patientes colligées au CHU pour le diagnostic et le suivi. Les tumeurs sont analysées histologiquement et classées après une étude immunohistochimique en groupes: luminal A, luminal B, Her2+, basal-like et non-classées. Résultats 54.3% des tumeurs sont du groupe luminal A, 16% luminal B, 11.3% Her2+, 11.3% basal-like et 7% non-classées. Le groupe luminal A renferme le plus faible taux de grade III, d'emboles vasculaires ainsi que de métastases; alors que le groupe des non-classées et basal-like représentent un taux élevé de grade III, une faible proportion d'emboles vasculaires et d'envahissement ganglionnaire. Ces facteurs sont significativement élevés dans les groupes luminal B et Her2+ avec un taux de survie globale de 78% et 76% respectivement. Dans le groupe luminal A, la survie globale des patientes est élevée (87%) alors qu'elle n'est que de 49% dans le groupe des triples négatifs (basal-like et non-classés). Conclusion Le groupe luminal B est différent du luminal A et il est de pronostic péjoratif vis à vis du groupe Her2+. Les caractéristiques clinicopathologiques concordent avec le profil moléculaire donc devraient être pris en considération comme facteurs pronostiques. PMID:23396646

    L’objectif de notre travail était d’étudier les conséquences socioprofessionnelles d’une libération chirurgicale du SCC. Il s’agit d’une étude transversale portant sur les sujets opérés pour un SCC d’origine professionnelle ; recensés dans le Service de Médecine de Travail et de Pathologies Professionnelles au CHU Tahar Sfar de Mahdia en Tunisie sur une période de 8 ans allant du 1 Janvier 2006 au mois Décembre 2013. Le recueil des données s’est basé sur une fiche d’enquête, portant sur la description des caractéristiques socioprofessionnelles, médicales, et sur le devenir professionnel des participants. Pour étudier les contraintes psychosociales au travail, nous avons adopté le questionnaire de Karasek. La durée d’arrêt de travail après libération chirurgicale du SCC était significativement liée à l’existence d’autres troubles musculo-squelettiques autre que le SCC, la déclaration du SCC en maladie professionnelle et à l’ancienneté professionnelle des salariés. Quant au devenir professionnel des salariés opérés, 50,7% ont gardé le même poste, 15,3% ont bénéficié d’un aménagement de poste et 33,8% ont bénéficié d’un changement de poste dans la même entreprise. Le devenir professionnel de ces salariés était corrélé à leurs qualifications professionnelles et au type de l’atteinte sensitive et/ou motrice du nerf médian à l’EMG. Un certain nombre de facteurs non lésionnels déterminaient la durée de l’arrêt de travail, alors que le devenir professionnel des opérés pour SCC dépendait essentiellement de leurs qualifications professionnelles et des données de l’électromyogramme. Il est certain que des travaux beaucoup plus larges permettraient d’affiner encore ces résultats. PMID:27800089

    Cri du chat syndrome is an inherited disease affecting multiple organ systems. Most characteristic is the anatomical abnormality of the larynx resulting in a cat-like cry. Issues important in developing an anaesthetic plan include: anatomical abnormalities of the airway, congenital heart disease, hypotonia, mental retardation, and temperature maintenance. We report the case of a 33-month-old patient with cri du chat syndrome undergoing patent ductus arteriosus (PDA) ligation and discuss the anaesthetic issues.

    2003-01-01

    The oxidation states of uranium contained in depleted uranium (DU) particles were determined by synchrotron radiation based micro-XANES, applied to individual particles in soil samples collected at Ceja Mountain, Kosovo. Based on scanning electron microscopy (SEM) with XRMA prior to micro-XANES, DU particles ranging from submicrons to about 30 microm (average size: 2 microm or less) were identified. Compared to well-defined standards, all investigated DU particles were oxidized. About 50% of the DU particles were characterized as UO2, the remaining DU particles present were U3O8 or a mixture of oxidized forms (ca. 2/3 UO2, 1/3 U3O8). Since the particle weathering rate is expected to be higher for U3O8 than for UO2, the presence of respiratory U3O8 and UO2 particles, their corresponding weathering rates and subsequent remobilisation of U from DU particles should be included in the environmental or health impact assessments.

    Objectives: Cri du chat syndrome is a genetic alteration associated with some oral pathologies. However, it has not been described previously any clinical relationship between the periodontal disease and the syndrome. The purpose of this comparative study was to compare periodontopathogenic flora in a group with Cri du chat syndrome and another without the síndrome, to assess a potential microbiological predisposition to suffer a periodontitis. Study Design: The study compared nineteen subjects with Cri du chat Syndrome with a control group of nineteen patients without it. All patients were clinically evaluated by periodontal probing, valuing the pocket depth, the clinical attachmente level and bleeding on probing. There were no significant differences between both groups. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola were detected by multiplex-PCR using 16S rDNA (microIDENT). Results: When A. actinomycetemcomitans, P. gingivalis, P. intermedia and T. denticola were compared, no statistically significant differences were found between the two groups (p>0.05). The value of T. forsythia was significantly higher for Cri du chat syndrome (31.6%) than for the control group (5.3%). The odds ratio for T. forsythia was 8.3. Conclusions: In the present study T. forsythia is associated with Cri du chat syndrome subjects and not with healthy subjects. Key words:Cri du Chat syndrome, periodontal health, microbiology, special care dentistry. PMID:24121919

    Nous avons étudié l'effet du titane et du niobium sur l'oxydation à 950circC d'un acier Fe-Cr chrominoformeur. La DRX in situ montre que le titane semble s'oxyder en formant Cr{2}TiO{5} et TiO{2} qui contribuent à une augmentation de la prise de masse des échantillons. Une partie du titane issu de ces oxydes semble doper la couche de chromine. Sa présence augmente la concentration en lacunes cationiques dans la chromine et augmente donc la diffusion du chrome dans la couche. Nous avons aussi montré que le niobium n'a pas d'influence sur l'oxydation de ce type d'acier à 950circC.

    L'association d'un cancer du col utérin avec une grossesse est une éventualité rare. Son incidence est assez mal évaluée, elle se situe selon les études entre 1 et 2/10 000. Lorsque la découverte en est faite, il faut conjuguer deux impératifs parfois totalement divergents: le traitement de la mère et la prise en charge du foetus. Cette association pose schématiquement quatre grands problèmes, qui sont: Celui du diagnostic, qui est loin d’être évident, compte tenu des remaniements cervicaux observés en début de gestation, le pronostic de l'affection, la date du traitement chirurgical et du délai entre le diagnostic et la prise en charge thérapeutique, enfin et de manière plus accessoire, le devenir de la grossesse et le mode d'accouchement. Nous rapportons une série de 5 cas de cancer du col utérin découverts au cours de la grossesse colligés dans notre service entre 2010 et 2013. La prise en charge thérapeutique est identique à celle des patientes en dehors de la grossesse même si quelques adaptations sont nécessaires du fait de l’état gravide, le pronostic du cancer ne semble pas être modifié par la grossesse.

    The overall energetical behaviour of a greenhouse is significantly affected by diurnal storage and nocturnal release of energy inside the soil, which is the only element with high thermal capacitance. Its specific part is analysed with a pre-existing dynamic simulation model. The first part of this paper studies the effects of 4kinds of heating exchangers along each month of an entire cultivation period: hot air convector, aerial metallic pipes with hot water circulation, radiant mulch or buried pipes with warm water circulation. The second part develops the hourly behaviour of both greenhouse and soil during a cold standard-day with each of the 4exchangers. The third part is a sensibility study to various classes of factors in the case of hot air convector exchanger: climatic environment, control policy, intrinsic properties of the greenhouse (soil characteristics, crop density, cover transparency). Le comportement énergétique global d'une serre agricole est influencé de manière parfois importante par le stockage diurne et la restitution nocturne d'énergie au sein de son sol, seul élément à grande capacité thermique. Le rôle spécifique joué par le sol est analysé en appliquant un modèle de simulation dynamique déjà existant. Une première partie compare les effets de 4types d'échangeurs de chauffage sur chaque mois d'une période de culture : aérotherme, tubes aériens à circulation d'eau chaude, paillage radiant ou tubes enterrés à circulation d'eau tiède. Une seconde partie développe le comportement horaire de la serre et du sol pour une journée-type froide en présence de chacun des échangeurs. Une troisième partie précise la sensibilité du bilan thermique de la serre et du sol à différents types de facteurs dans le cas d'un échangeur par aérotherme: environnement climatique, politique de contrôle de la serre, propriétés intrinsèques de la serre (caractéristiques du sol, densité de culture, transparence de la couverture).

    The Pic du Midi Observatory has built a strong expertise in polarimetry over the years, with the development of instruments such as Sterenn and MUSICOS. The 2m Telescope Bernard Lyot (TBL) is now fully dedicated to spectropolarimetric studies with the NARVAL instrument, which covers in a unique exposure the 375-1050 nm spectral range with a spectral resolution of 65,000, and gives access to the 4 Stokes parameters. This lead to significant progress in our understanding of magnetism over the whole HR diagram, thanks to detections down to the Gauss level and the continuous follow-up of stars during many years. The future is also very promising, with the development of the Neo-Narval instrument which will be stabilized in velocimetry down to 3 m/s, allowing in particular magnetic jitter vs. exoplanet detections (1st light planned in 2019) and SPIP, which will cover the near-infrared range. I will present illustrative recent results obtained with the NARVAL instrument, as well as the future instrumentation.

    A new syndrome was identified in 1963, when Lejeune et al. reported a genetic disease resulting from a partial or total deletion on the short arm of chromosome 5 (5p-) and named it the cri du chat syndrome (CdCS). This term makes reference to the main clinical feature of the syndrome, a high-pitched monochromatic cat-like crying, that usually disappears in the first years of life. CdCS is one of the most common chromosomal deletion syndromes in humans, with an incidence of 1:15.000-1:50.000 live-births. Our purpose was to review different aspects of this syndrome (concept, epidemiology, aetiology, clinical features, diagnostic methods and prognosis) emphasizing both: the breakthrough in this field introduced by new cytogenetic and molecular techniques, and the orofacial manifestations most frequently reported. The main orofacial anomalies registered were mandibular microretrognathia, high palate but rarely cleft, variable malocclusion (frequently anterior open-bite), enamel hypoplasia, poor oral hygiene, generalized chronic periodontitis, and retardation of tooth eruption, although there is not enough evidence to support any clear association between these pathologies and the CdCS.

    The origin and variation of acupoints on the Du channel are investigated by analyzing and studying the number and distribution of points recorded in the ancient medical works. It is found that the amount and distribution of the points were different in different ages. The distributions of the points were not only located on the midline of the face, head, nape and posterior midline but also on both sides of the spine from the period of Neijing (Inner Canon) to that of Zhenjiu Jiayi Jing (A-B Classic of Acupuncture and Moxibustion). Since the period of Tongren Shuxue Zhenjiu Tujing (Illustration Classic of Acupoints on Bronze Statue) in the Song dynasty, only those points of the midline from the face, nape to the spine are remained there until now. Meanwhile, the amount of points were also varied because of the cognition to the points on the spine. Huangdi Neijing Taisu (Grand Simplicity of Inner Canon of Huangdi) compiled in the Tang Dynasty first mentioned the arguments about the varied points on the channel. The records by Yang Shangshan and Wang Bing indicate that the main differences on the cognition of the channel andits points appeared during the period of the Tang Dynasty to the Song Dynasty.

    Résumé Objectif Informer les médecins de famille quant à l’efficacité, à l’innocuité, aux effets sur la santé publique et à la rentabilité du vaccin 9-valent contre le virus du papillome humain (VPH). Qualité des données Des articles pertinents publiés dans PubMed jusqu’en mai 2015 ont été examinés et analysés. La plupart des données citées sont de niveau I (essais randomisés et contrôlés et méta-analyses) ou de niveau II (études transversales, cas-témoins et épidémiologiques). Des rapports et recommandations du gouvernement sont aussi cités en référence. Message principal Le vaccin 9-valent contre le VPH, qui offre une protection contre les types 6, 11, 16, 18, 31, 33, 45, 52 et 58 du VPH, est sûr et efficace et réduira encore plus l’incidence des infections à VPH, de même que les cas de cancer lié au VPH. Il peut également protéger indirectement les personnes non immunisées par l’entremise du phénomène d’immunité collective. Un programme d’immunisation efficace peut prévenir la plupart des cancers du col de l’utérus. Les analyses montrent que la rentabilité du vaccin 9-valent chez les femmes est comparable à celle du vaccin quadrivalent original contre le VPH (qui protège contre les types 6, 11, 16 et 18 du VPH) en usage à l’heure actuelle. Toutefois, il faut investiguer plus en profondeur l’utilité d’immuniser les garçons avec le vaccin 9-valent contre le VPH. Conclusion en plus d’être sûr, le vaccin 9-valent protège mieux contre le VPH que le vaccin quadrivalent. Une analyse coûtefficacité en favorise l’emploi, du moins chez les adolescentes. Ainsi, les médecins devraient recommander le vaccin 9-valent à leurs patients plutôt que le vaccin quadrivalent contre le VPH.

    L’ hydatidose est une anthropo-zoonose due au développement chez l'homme de la forme larvaire du taenia Echinococcus granulosis. La plupart des kystes hydatiques se localisent dans le foie et les poumons. Le kyste hydatique du cordon spermatique est extrêmement rare avec seulement 4 cas rapportés dans la littérature. Les auteurs rapportent dans cet article un nouveau cas d'hydatidose du cordon spermatique. Il s'agissait d'un homme de 40 ans qui consultait pour des douleurs scrotales évoluant depuis huit mois. L'examen clinique a mis en évidence une tuméfaction mobile, inguino-scrotale, droite. L’échographie testiculaire a objectivé une hernie inguinale droite associée à deux kystes épididymaires bilatéraux. Le patient a été opéré pour cure de son hernie avec découverte en per-opératoire d'un kyste du cordon spermatique qui a été réséqué. L'examen anatomopathologique a conclu à une hydatidose du cordon spermatique. PMID:22384304

    The DOE, after an independent review, has adopted an Environmental Assessment (EA) prepared by the US Department of Agriculture (USDA) which evaluates use of an Integrated Wildlife Damage Management approach at Argonne National Laboratory-East (ANL-E) in DuPage County, Illinois (April 1995). In 1994, the USDA issued a programmatic Environmental Impact Statement (EIS) that covers nationwide animal damage control activities. The EA for Management of Wildlife Causing Damage at ANL-E tiers off this programmatic EIS. The USDA wrote the EA as a result of DOE`s request to USDA to prepare and implement a comprehensive Wildlife Management Damage Plan; the USDA has authority for animal damage control under the Animal Damage Control Act of 1931, as amended, and the Rural Development, Agriculture and Related Agencies Appropriations Act of 1988. DOE has determined, based on the analysis in the EA, that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act of 1969 (NEPA). Therefore, the preparation of an EIS is not required. This report contains the Environmental Assessment, as well as the Finding of No Significant Impact (FONSI).

    Le diaphragme sous aortique se caractérise par une certaine latence clinique et une faible morbi-mortalité. La chirurgie reste le traitement de choix malgré un réel risque de récurrence à long terme. Nous rapportons 18 patients opérés entre Avril 1994 et Mars 2011 pour diaphragme sous aortique d’âge moyen de 18,1±9,7 ans avec 11 patients de sexe masculin. Le diaphragme était de nature fibreuse chez 13 patients et fibro-musculaire chez 5 patients. Tous les patients ont été opérés par résection de diaphragme associée à une myectomie, une plastie aortique, une fermeture de communication interventriculaire et une ligature de canal artériel perméable respectivement chez 3, 3, 2 et 2 patients. La Mortalité opératoire était nulle et sans aucun cas de trouble de conduction postopératoire. Le suivi a duré en moyenne 44,3±36,8 mois sans aucun décès tardif. Deux patients ont présenté une récidive de diaphragme qui a nécessité une réopération avec bonne évolution. La tendance actuelle dans la chirurgie du diaphragme se fait vers des interventions précoces et des résections plus extensives. Cependant, le risque de récidive impose une surveillance échographique systématique et rapprochée. PMID:27516830

  4. Modelisation du Signal Radar EN Milieu Stratifie et Evaluation de Techniques de Mesure de L'humidite du Sol

    NASA Astrophysics Data System (ADS)

    Boisvert, Johanne

    La presente etude se penche sur des problemes relies a l'echantillonnage de l'humidite de sol et a l'estimation du signal radar sur sols nus. Le travail se divise en deux volets. Le volet 1 evalue trois techniques de mesure de l'humidite du sol (gravimetrie, reflectometrie temporelle et sonde dielectrique) et deux protocoles d'echantillonnage. Dans le volet 2, un modele de simulation du signal en milieu stratifie est developpe, et les estimes de signal obtenus sont compares aux estimes bases uniquement sur une valeur moyenne d'humidite du sol prise sur une profondeur fixe d'echantillonnage. Les differences entre les deux estimes dependent de la frequence et du choix judicieux de la profondeur d'echantillonnage; elles sont plus importantes aux faibles angles et en polarisation HV, puis VV. Le modele de simulation a aussi ete utilise pour etudier la profondeur de penetration du signal et en deduire la profondeur optimale d'echantillonnage en tenant compte des caracteristiques du signal. Une variation de 25 ^circ de l'angle d'incidence a peu d'effet sur la profondeur de penetration en bande Ku; l'ecart reste inferieur ou egal a 0,5 cm en bande C mais peut atteindre 1,3 cm en bande L. L'impact de la polarisation est nul en bande Ku mais croi t avec l'angle d'incidence en bande C et L. A 50^circ, il est, en moyenne de 1 cm en bande C et de 2 cm en bande L. En polarisation VV, la profondeur croi t avec une augmentation de l'angle alors que l'effet est inverse en polarisation HH. Deux methodes pour estimer la profondeur d'echantillonnage en conditions operationnelles sont presentees. Lorsqu'on inverse un modele pour estimer l'humidite du sol a partir du signal, ces methodes permettent aussi d'estimer l'epaisseur de sol representee par l'humidite ainsi estimee.

    Introduction Le suicidé est le sujet mort par suicide et le suicidant est la personne ayant fait des tentatives de suicide. L'objectif de cette étude porte sur l'analyse épidémiologique des suicides dans la région de Dakar. Méthodes Par une étude rétrospective portant sur les registres du service d'anatomie pathologique de l'Hôpital Aristide Le Dantec, nous rapportons 143 suicides sur 10 ans. Le traitement et l'analyse des données ont été faits sur Epidata version 2.1 b pour la saisie et Epiinfo version 6.04 fr pour l'analyse. Résultats A Dakar, les morts par suicide restent peu fréquentes au regard de la mortalité générale. Les hommes se suicident deux fois plus que les femmes et le suicide reste l'apanage de l'adulte jeune dont l'âge se situe entre 21 et 30 ans. Les suicidés résident le plus souvent en zone périurbaine et ils commettent cet acte dans la majorité des cas en période de froid (pendant les mois de janvier, février et mars), plus avant midi et en soirée qu'en après-midi. Aussi 97.2% des suicidés ont utilisé un seul moyen pour se suicider et le suicide complexe (utilisation de plusieurs moyens) a concerné seulement un cas dans notre étude. La pendaison reste le mode le plus utilisé. Conclusion Les hommes préfèrent donc des moyens de suicides violents (pendaison, arme à feu et arme blanche) alors que les femmes et les adolescents (tout sexe confondu) utilisent les intoxications. Le recueil des facteurs concourant au suicide permettrait une prévention de ce dernier. PMID:23847707

    Low-grade heat from geothermal wells can now be harnessed to produce electricity by using Du Pont ''Freon'' IF as the power conversion fluid. The new system was developed by Turbonetics Energy Inc. The company's Organic Rankine Cycle (ORC) system takes advantage of the low boiling point (117F) of Du Pont ''Freon'' TF. Geothermal energy is harnessed by utilizing the heat from 200F to 400F water to vaporize the ''Freon'' power fluid. Then the fluid expands through a turbine and drives a generator. The system can produce from 600 kW of electric power.

    L'hypercholestérolémie est étroitement liée au stress oxydatif. Lorsqu'il y a trop de cholestérol qui circule dans le sang, il n'est pas utilisé en totalité par les cellules et il risque de s'accumuler dans les vaisseaux sanguins. Cela peut entrainer la formation des plaques d'athérosclérose qui gênent la circulation sanguine et provoquent des accidents cardiovasculaires. Le stress oxydatif apparait très tôt dans l'histoire des complications du diabète de type 2, et est lié à l'oxydation du glucose mais aussi à la peroxydation lipidique. Le cholestérol-HDL est un marqueur important du stress oxydatif par sa capacité à faciliter la métabolisation du cholestérol, sa baisse est souvent considérée comme la source de beaucoup d'inquiétudes. L'objectif est l’évaluation de la variation du taux de cholestérol-HDL, marqueur du stress oxydatif, chez les patients diabétiques de type 2 dans la population congolaise. Nous avons inclus dans cette étude prospective des cas témoins des patients diabétiques de type 2 reconnus et diagnostiqués, et des témoins non diabétiques appariés selon l’âge et le sexe. Parallèlement au bilan biologique classique, une analyse d'un des facteurs de risque du stress oxydatif a été réalisée: baisse de HDL-Cholestérol. L’âge moyen des 30 patients diabétiques (47,77±10,78 ans) était comparable à celui des 30 témoins (48,83±10,73 ans). Une baisse significative du cholestérol-HDL dans le sang était observée chez 100% des diabétiques et 50% des témoins (p=0,0000). L'augmentation du HDL cholestérol permet d’éliminer le mauvais cholestérol en excès en nettoyant les tissus et en ramenant le cholestérol vers le foie. Lors du diabète de type 2 on constate une baisse sanguine sensible du taux de HDL-cholestérol, qui est signe indicateur du stress oxydatif. PMID:25767660

    Nous rapportons l'observation d'une fillette âgée de 7ans qui reçue dans un tableau de syndrome sub-occlusif avec une douleur abdominale aigue paroxystique siégeant au niveau de l'épigastre associée à des vomissements et un arrêt des matières. L'examen physique mettait en évidence une sensibilité à la palpation de l'épigastre. L'échographie abdominale a montré une formation tissulaire intra péritonéale mal limitée sans caractère vasculaire au doppler, exerçant un effet de masse sur les structures de voisinage ; les vaisseaux mésentériques étaient en position normale. A la tomodensitométrie cette masse correspondait à une formation lipomateuse bien limitée exerçant un effet de masse sur le caecum avec un volvulus du grêle. Le diagnostic de volvulus du grêle sur lipome mésentérique a été retenu. L'exploration chirurgicale confirmait ce diagnostic. Une détorsion grélique et une énucléation lipomateuse étaient réalisées. Les suites opératoires étaient simples après un recul de 6 mois. L'examen anatomopathologique confirmait la nature lipomateuse de la masse. PMID:28819497

    Le cancer du sein est le premier cancer féminin en termes d'incidence et de mortalité. Au Maroc, il vient au premier rang des cancers de la femme avant celui du col utérin Il constitue un problème de santé publique. Son pronostic est étroitement lié au stade auquel le diagnostic est posé. Il s'agit d'une pathologie dont les moyens diagnostiques sont de nos jours développés, allant de la détection précoce à la mise en évidence de lésions infra-cliniques, ce qui a nettement amélioré le pronostic dans les pays développés. Ce travail que nous présentons a pour objectif d'identifier dans notre pratique quotidienne, les facteurs qui amènent les patientes à consulter à des stades tardifs. Une étude rétrospective a été menée de janvier 2012 à janvier 2013 portant sur 130 patientes porteuses d'un cancer du sein au sein du service d'onco-radiotherapie CHU Mohammed VI Marrakech. Un questionnaire a été élaboré et dument renseigné en ayant recours aux dossiers des malades. Ainsi 63,07% des patientes consultaient au-delà de six mois avec un délai moyen de consultation de 8,47 mois avec comme motif de consultation des lésions classées T4 dans 27,69%, et des tumeurs d'emblée métastatiques dans 13,84%. Les facteurs retrouvés à l'interrogatoire étaient le manque de moyens financiers 40%, l’éloignement des structures sanitaires dans 23%, les habitudes socioculturelles avec les traitements traditionnels en première intention 20%, et l'insuffisance de prise en charge thérapeutique 7%. Cependant, pris individuellement, aucune concordance significative n’était retrouvée entre ces facteurs et le long délai diagnostique. Dans notre pratique, c'est la conjonction de la triade ignorance, indigence et habitudes socioculturelles qui constituent le facteur essentiel du diagnostic tardif des cancers du sein. PMID:26327999

  20. Prédiction des vibrations du stator d'une machine à réluctance variable en fonction du courant absorbé

    Camus, F.; Gabsi, M.; Multon, B.

    1997-02-01

    In order to predict the radial vibration of the stator core of a Doubly Salient Switched Reluctance Motor (D.S.S.R.M.), different causes of vibrations are considered. In this kind of machine, electromagnetic stress is found to be the most significant cause of vibrations. The local magnetic stress distribution, depending on magnetic field and finally on the phase current, is calculated in the case of an unsatured operation. This magnetic stress acts in two ways: a tangential force (torque) and a radial attractive force. This radial force excites the vibration modes of the stator, this vibration behaviour is measured in the aligned position and is identified as a transfert function. Finally several experiments show the good accuracy of this simple model. This model will be later used to study the effect of phase current and of static converter on vibration and acoustic noise emitted by the D.S.S.R.M. L'étude du bruit et des vibrations dans le matériel électrique fait intervenir plusieurs systèmes physiques couplés. Le modèle complet est complexe et ne permet pas d'études paramétriques simples de la structure de la machine, de son alimentation et cela pour différents points de fonctionnement. Dans cet article est présenté un modèle simple permettant de prédire l'accélération radiale d'un Moteur à Réluctance Variable à Double Saillance (M.R.V.D.S.) en fonction du courant d'alimentation. Ce modèle permettra d'étudier ultérieurement l'influence de l'alimentation sur le comportement vibratoire de la machine. En premier lieu, les différentes sources de vibrations d'une machine tournante sont évoquées, pour finalement ne s'intéresser qu'aux efforts d'origine magnétique qui sont prépondérants dans les M.R.V.D.S. Le calcul de ces efforts en fonction du courant est présenté dans le cas d'une machine fonctionnant en régime linéaire (sans saturation magnétique). Ces efforts sont décomposés en une force tangentielle créant le couple de rotation

    En Tunisie, le cancer du sein touche des femmes jeunes avec une taille moyenne au moment du diagnostic à 5 cm. Ces particularités font que la chirurgie radicale reste prédominante. Nous présentons dans ce travail l'expérience de notre équipe en matière de chirurgie conservatrice du cancer du sein. Le but de ce travail est d’évaluer les résultats de ce traitement. Etude rétrospective longitudinale, sur une période de 75 mois. Nous avons inclus toutes les patientes ayant bénéficié d'un traitement conservateur pour une tumeur maligne du sein. Ont été analysés: les caractéristiques épidémiologiques, les aspects radiologiques et histologiques. Le suivi des malades s'est basé sur la détection des récidives. Nous avons évalué le résultat esthétique à la fin de la radiothérapie. Le traitement conservateur a été réalisé dans 23.8% des cas. Le taux de récidives locales était de 6.8% avec une corrélation significative pour une taille tumorale > 30 mm (p= 0.009), l'association d'une composante intracanalaire (p= 0.035), le statut triple négatif (p= 0.003) et des marges d'exérèse < 5mm sans recoupes per-opératoires (p = 0.045). Les facteurs suivants étaient significativement liés au risque de survenue de métastases à distance: le statut triple négatif (p= 0.003), taille tumorale > 30mm (p = 0.006) et l'atteinte ganglionnaire (p = 0.001). Le résultat esthétique était satisfaisant dans 90% des cas. L'augmentation du nombre de patientes pouvant bénéficier d'une chirurgie conservatrice, doit passer impérativement par le développement et la promotion du diagnostic précoce et du dépistage par la mammographie.

Le but de notre travail est d'évaluer la conformité de la tenue du partogramme au sein de notre maternité et de proposer des axes d'amélioration de la qualité de sa tenue. il s'agit d'une étude rétrospective par audit clinique, effectuée sur 400 dossiers des patientes ayant accouché dans la maternité universitaire de Kairouan du 1er Janvier au 31 décembre 2014. Le référentiel utilisé est celui de la Haute Autorité de Santé (2006) comportant 29 critères divisés en 3 domaines (PARTOten, PARTOobs, PARTOeve). le Taux de Conformité Globale (TCG) de la tenue du partogramme dans notre audit était de 55,9%. Pour le domaine I « La tenue du partogramme » (PARTOten), le TCG était de 88,9%. Pour le domaine II « la traçabilité du déroulement du travail » (PARTOobs), le TCG était de 51,4%. Pour le domaine III « la traçabilité des actes, des évènements et des traitements au cours du travail » (PARTOeve), le TCG était de 27,4%. Notre étude a permis de dégager plusieurs points à améliorer. Le but ultime de l'Audit Clinique est l'amélioration des pratiques professionnelles, de ce fait nous allons mettre en place un plan d'action (formation, sensibilisation…) qui sera suivi par une réévaluation afin de vérifier la pérennité des actions correctives.

    Robichaud, Luc

    Les fluctuations du vide, qui consistent en l'apparition momentanee de particules, ce qui est permit par le principe d'incertitude de Heisenberg, joue un role primordial dans les processus photoniques, en particulier les processus non-lineaires. Par la manipulation de ces fluctuations du vide a l'aide de confinement optique, on retrouve deux phenomenes particuliers : l'intensification de la fluorescence parametrique (Walker, 2008) et l'inhibition de la generation du second harmonique (Collette, 2013). Dans ce travail, on presente les resultats dans le cas classique ; c'est-a-dire sans fluctuations du vide et confinement. Par la suite, on presente les effets des fluctuations du vide et du confinement, ce qui mene aux deux effets mentionnes. Dans le cas de la fluorescence parametrique, le bruit quantique sur le champ interne et externe est calcule, le role du desaccord de phase dans le modele est expose et une generalisation tridimensionnelle est etudiee afin de generaliser la conception du modele d'un cas unidimensionnel a un cas tridimensionnel planaire. Dans le cas de la generation du second harmonique, les difficultes d'un modele purement tridimensionnel sont exposees et ensuite le cas limite planaire est etudie.

  4. An alternative for cost-effective remediation of depleted uranium (DU) at certain environmental restoration sites

    Numerous sites in the United States and around the world are contaminated with depleted uranium (DU) in various forms. A prevalent form is fragmented DU originating from various scientific tests involving high explosives and DU during weapon development programs, at firing practice ranges, or war theaters where DU was used in armor-piercing projectiles. The contamination at these sites is typically very heterogeneous, with discreet, visually identifiable DU fragments mixed with native soil. That is, the bulk-averaged DU activity is quite low, while specific DU fragments, which are distinct from the soil matrix, have much higher specific activity. DU is best known as a dark, black metal that is nearly twice as dense as lead, but DU in the environment readily weathers to a distinctive bright yellow color that is readily visible. While the specific activity of DU is relatively low and presents only a minor radiological hazard, the fact that it is radioactive and visually identifiable makes it desirable to remove the DU contamination from the environment.

    2000-12-01

    Les détections de fluctuations de température du fond diffus cosmologique (CMB pour''Cosmic Microwave Background'' ) s'accumulent depuis près de 10 ans.La connaissance du spectre angulaire des fluctuations nous permet d'avoir accès à la physique de l'universlorsqu'il avait environ100 000 ans et donc de déterminerles paramètres cosmologiques.Ce manuscrit présentedifférentes méthodes statistiques qui permettent de passer de l'information disponible sur les observations du CMB aux paramètres cosmologiques. Après unedescription du CMB au sein du modèle du Big-Bang et de l'inflation, je montre que la méthode de vraisemblance permet d'estimer les puissances en bande ou les paramètres cosmologiques à partir d'une carte ou d'un ensemble de pixels (étude des expériences COBE, MAX et Saskatoon).Ensuite, je décris les méthodes qui permettent d'utiliser les puissances en bandedes observations du CMB publiées dans la littérature pour déterminer les paramètres cosmologiques. Ces méthodes sont plus rapides que l'analyse de vraisemblance mais supposent différentes hypothèses sur lesquelles j'insiste. A partir des analyses de vraisemblance que j'ai effectuées, j'ai pu développé d'une part, uneméthode approximative quipermet de mieuxreproduire la forme de la fonction de vraisemblance, et d'autre part une nouvelle technique pour estimer la qualité d'ajustement des modèles préférés. Ces techniques ont été appliquées sur les données actuelles,incluant les plus récentes BOOMERANG et MAXIMA, pour déterminer les paramètres cosmologiques. Les conclusions sont présentées dans ce mémoire.Enfin, une dernière partie est dédiée à l'expérience ARCHEOPS, expérience ballon basée sur la technologie de Planck.

  19. Cost-Effective Remediation of Depleted Uranium (DU) at Environmental Restoration Sites

    SciTech Connect

    MILLER,MARK; GALLOWAY,ROBERT B.; VANDERPOEL,GLENN; JOHNSON,ED; COPLAND,JOHN; SALAZAR,MICHAEL

    1999-11-03

    Numerous sites in the United States and around the world are contaminated with depleted uranium (DU) in various forms. A prevalent form is fragmented DU originating from various scientific tests involving high explosives and DU during weapon-development programs, at firing practice ranges, or in war theaters where DU was used in armor-piercing projectiles. The contamination at these sites is typically very heterogeneous, with discrete, visually identifiable DU fragments mixed with native soil. The bulk-averaged DU activity is quite low, whereas DU fragments, which are distinct from the soil matrix, have much higher specific activity. DU is best known as a dark metal that is nearly twice as dense as lead, but DU in the environment readily weathers (oxidizes) to a distinctive bright yellow color that is quite visible. While the specific activity (amount of radioactivity per mass of soil) of DU is relatively low and presents only a minor radiological hazard, the fact that DU is radioactive and visually identifiable makes it desirable to remove the DU ''contamination'' from the environment. The typical approach to conducting this DU remediation is to use radiation-detection instruments to identify the contaminant and then to separate it from the adjacent soil, packaging it for disposal as radioactive waste. This process can be performed manually or by specialized, automated equipment. Alternatively, a more cost-effective approach might be simple mechanical or gravimetric separation of the DU fragments from the host soil matrix. At SNL/NM, both the automated and simple mechanical approaches have recently been employed. This paper discusses the pros/cons of the two approaches.

    1986-01-01

    An overview of the ACTS Experiments Program is presented. ACTS is being developed and will flight test the advanced technologies associated with: a Ka-band multibeam antenna, onboard signal processing and switching as well as laser communications. A nominal 3 yr experiments program is planned. Through the experiments program, the capabilities of the ACTS system will be made available to U.S. industry, university and government experimenters to test, prove the feasibility and evaluate the key ACTS system technologies. Communication modes of operation using the baseband processor and microwave switch matrix are presented, along with the antenna coverage pattern. Potential experiment categories are also presented and briefly discussed. An overall schedule of activities associated with the experiments program is outlined. Results of the ACTS Experiments Program will provide information vital to successful industry implementation of ACTS technology in a future operational system.

    I show that the quantum measurement problem can be understood if the measurement is seen as a "speech act" in the sense of modern language theory. The reduction of the state vector is in this perspective an intersubjective -- or, better, a-subjective -- symbolic process. I then give some perspectives on applications to the "Mind-Body Problem".

    La paralysie néonatale unilatérale du nerf radial est rare, son diagnostic est essentiellement clinique, elle peut-être diagnostiquée à tort en tant que paralysie du plexus brachial. Nous rapportons un cas clinique. A l'examen clinique du nouveau-né; l'extension du poignet, du pouce et des articulations métacarpo-phalangiennes était impossible, alors qu'il y avait une conservation de la prono-supination et la flexion du poignet et des mouvements de l’épaule et du coude. Le diagnostic de la paralysie du plexus brachial était écarté cliniquement devant la mobilisation active de l’épaule et la flexion du coude. Notre patient a bénéficié de kinésithérapie pour éviter l'apparition d'attitudes vicieuses et d'amyotrophie. L'extension active du poignet était obtenue après deux mois. PMID:26587133

    Résumé Objectif Explorer les raisons pour lesquelles la perte de poids à long terme échoue la plupart du temps et évaluer les conséquences de diverses trajectoires pondérales, y compris la stabilité, la perte et le gain. Source des données Les études qui évaluent les paramètres pondéraux dans la population sont en majorité observationnelles. Des données probantes de niveau I ont été publiées pour évaluer l’influence des interventions relatives au poids sur la mortalité et la qualité de vie. Message principal Seulement un petit pourcentage des personnes qui désirent perdre du poids réussissent à le faire de manière durable. La mortalité est la plus faible chez les personnes se situant dans la catégorie de poids élevé-normal et surpoids. La trajectoire pondérale la plus sécuritaire est la stabilité du poids avec une optimisation de la condition physique et métabolique. Il est démontré que la mortalité est plus faible chez les personnes ayant des comorbidités reliées à l’obésité si elles perdent du poids. Il est aussi établi que la qualité de vie sur le plan de la santé est meilleure chez les personnes obèses qui perdent du poids. Par contre, la perte de poids chez une personne obèse autrement en santé est associée à une mortalité accrue. Conclusion La perte de poids est recommandable seulement chez les personnes qui ont des comorbidités reliées à l’obésité. Les personnes obèses en santé qui veulent perdre du poids devraient être informées qu’il peut y avoir des risques à le faire. Une stratégie qui se traduit par un indice de masse corporelle stable avec une condition physique et métabolique optimisée, peu importe le poids, est l’option d’intervention la plus sécuritaire en ce qui concerne le poids.

Nous avons mené une étude transversale, exhaustive incluant les 71 médecins généralistes exerçant dans les établissements de soins de santé de base du secteur public et privé de la province de Benimellal. Le but était d’évaluer leurs connaissances et leur participation au dépistage du cancer du col. Méthodes Nous avons mené une étude transversale, exhaustive incluant les 71 médecins généralistes exerçant dans les établissements de soins de santé de base du secteur public et privé de la province de Benimellal. Le but était d’évaluer leurs connaissances et leur participation au dépistage du cancer du col. Résultats Le niveau de connaissance était relativement modeste, 22 médecins généraliste avaient répondu à la question sur l'incidence du cancer du col au Maroc, Parmi eux (81,8%) avaient donné une réponse incorrecte. L'Herpes Papilloma virus comme facteur de risque du cancer du col a été identifié par seulement 21% des médecins généralistes. La participation au dépistage était également défaillante, 92,8% n'avaient jamais pratiqué le FCV chez leurs patientes à cause principalement du manque de formation (95,5%). Conclusion Les résultats montrent la nécessité d'améliorer les connaissances théoriques et pratique des médecins généralistes concernant le dépistage du cancer du col. PMID:23785557

  2. Draconian dress act repealed.

    PubMed

    Mhone, C

    1994-01-01

    The Dress Act was put into place in Malawi by the government of President Kamuzu Banda after the long period of direct colonialism. The act made it illegal for women in Malawi to be seen publicly wearing dresses which did not completely cover their knees or wearing pants; men had to wear their hair short. Police officers even scrutinized women's attire at private house parties and in homes. The autocratic political structure established by Banda, however, was voted out in a referendum June 14, 1993. Pressure by opposition forces such as the United Democratic Front forced a repeal of the act on November 16 of the same year. The repeal was vigorously attacked by female Parliament members as a move which would result in moral degradation and an increase in the level of sexual harassment against women. Other citizens and tourists have generally detested the act. The act has most certainly kept many potential visitors from vacationing in Malawi. Some expert observers think that repeals of the Dress Act, the Forfeiture Act, and legislation which allowed the government to detain opposition figures without trial were done to garner support from the Paris Club for the resumption of balance of payments support suspended due to the country's poor human rights record.

    The production of H2O2, which is essential to thyroid hormone synthesis, involves two NADPH oxidases: dual oxidases 1 and 2 (DuOx1 and DuOx2). A functional study with human DuOx genes and their 5'-flanking regions showed that DuOx1 and -2 promoters are different from thyroid-specific gene promoters. Furthermore, their transcriptional activities are not restricted to thyroid cells. While regulation of Tg (thyroglobulin) and TPO (thyroperoxidase) expression have been extensively studied, DuOx2 promoter regulation by hormones and transcriptional factors need to be more explored. Herein we investigated the role of TSH, insulin and insulin-like growth factor 1 (IGF-1), as well as the cAMP effect on DuOx2 promoter (ptx41) activity in transfected rat thyroid cell lines (PCCL3). We also assessed DuOx2 promoter activity in the presence of transcriptional factors crucial to thyroid development such as TTF-1 (thyroid transcription factor 1), PAX8, CREB, DREAM, Nkx2.5 and the coactivator TAZ in HeLa and HEK 293T-transfected cells. Our results show that TSH and forskolin, which increase cAMP in thyroid cells, stimulated DuOx2 promoter activity. IGF-1 led to pronounced stimulation, while insulin induction was not statistically different from DuOx2 promoter basal activity. All transcriptional factors selected for this work and coactivator TAZ, except DREAM, stimulated DuOx2 promoter activity. Moreover, Nkx2.5 and TAZ synergistically increased DuOx2 promoter activity. In conclusion, we show that DuOx2 expression is regulated by hormones and transcription factors involved in thyroid organogenesis and carcinogenesis, reinforcing the importance of the control of H2O2 generation in the thyroid.

In conclusion, we show that DuOx2 expression is regulated by hormones and transcription factors involved in thyroid organogenesis and carcinogenesis, reinforcing the importance of the control of H2O2 generation in the thyroid.

    A case of prenatally detected cri du chat syndrome (5p-) is reported. Amniocentesis was performed following an abnormal ultrasound finding of isolated moderate bilateral ventriculomegaly. The karyotype showed a terminal deletion of the short arm of chromosome 5 including the critical region 5p15 for cri du chat syndrome. This was confirmed by fluorescence in situ hybridisation (FISH). Isolated mild ventriculomegaly may be a non-specific marker for cri du chat syndrome.

    1993-01-01

    Over the last decade, the demand for reliable mobile satellite communications (satcom) for voice, data, and video applications has increased dramatically. As consumer demand grows, the current spectrum allocation at L-band could become saturated. For this reason, NASA and the Jet Propulsion Laboratory are developing the Advanced Communications Technology Satellites (ACTS) mobile terminal (AMT) and are evaluating the feasibility of K/Ka-band (20/30 GHz) mobile satcom to meet these growing needs. U.S. industry and government, acting as co-partners, will evaluate K/Ka-band mobile satcom and develop new technologies by conducting a series of applications-oriented experiments. The ACTS and the AMT testbed will be used to conduct these mobile satcom experiments. The goals of the ACTS Mobile Experiments Program and the individual experiment configurations and objectives are further presented.

    Nous avons etudie les molecules de furanne ( rm C_4H_4O) et de thiophene (rm C_4H_4O) au moyen de la spectroscopie de diffusion inelastique d'electrons. Pour (rm C_4H_4O), les spectres realises dans differentes conditions d'energie d'impact et d'angle de diffusion contiennent des singularites ou des families de pics correspondant a: (1) des vibrations de l'etat fondamental dans le domaine 0-0.5 eV, (2) des etats triplets ^3 B_1 et ^3 A_1 qui dominent la region 3-5.5 eV, (3) des etats de valences, entre 5 et 10 eV, dont certains son accompagnes de progressions vibrationnelles, soit ~ A _1B_2, ~ B ^1A_1 et ~ C ^1A_1, (4) toujours entre 5 et 10 eV, deux series de Ryhdberg (rm 1a_2to nda_2 et rm 1a_2to npb_2) qui convergent vers la premiere limite d'ionisation de la molecule, avec une progression vibrationnelle associee au mdoe nu_4 pour la seconde, et une troisieme serie (rm 2b_1to nsa_1 ) convergent vers la seconde limite d'ionisation accompagnee de la progression de mode nu _1. Pour rm C_4H_4S, nos spectres presentent les memes etats de vibration et les memes etats triplets que pour rm C_4H _4O. Nous avons releve egalement, dans la region de 5 a 10 eV, des etats de valence ~ A ^1A_1 (ou ~ A ^1B_2), ~ B ^1A_1 (ou ~ B ^1B _2) et ~ C ^1A_1 (ou ~ C ^1B_2). Pour la premiere fois, par la spectroscopie de diffusion inelastique d'electrons, de nombreux pics ont ete identifies et attribues, dans le cadre de ce travail. Il s'agit, notamment, des etats de vibration de l'etat electronique fondamental de ces molecules et egalement de certains etats de Rydberg dans le cas du furanne.

    Introduction Le cancer du sein représente un problème de santé publique majeur au Maroc. C'est le premier cancer chez la femme. L'objectif de ce travail était d'évaluer les connaissances des médecins généralistes (MG) en matière de dépistage du cancer du sein dans la préfecture de Mohammedia Maroc. Méthodes Nous avons mené une étude transversale, descriptive, exhaustive incluant les 97 MG exerçant dans les établissements de soins de santé de base du secteur public et privé de la province de Mohammedia. Résultats Le taux de participation était de 87%. L'âge moyen des MG était de 49,6 ± 8,1. Quatre-vingt pour cent (n=55) des MG ont donné une incidence incorrecte, 77,6% (n=85) ont reconnu l'existence d'un plan national de prévention et de contrôle du cancer (PNPCC) au Maroc, et 67,1 des MG ont rapporté l'existence d'un registre du cancer au Maroc. Le secteur d'activité était associé significativement avec les connaissances des MG sur le PNPCC et sur l'existence d'un guide de détection précoce du cancer du sein avec respectivement (p=0,003 et p=0,001). Une association significative entre l'ancienneté et l'existence d'un guide de détection précoce du cancer du sein et d'un registre du cancer du sein a été retrouvée avec (respectivement p=0,005 et p=0.002). Conclusion À la lumière de ces résultats il faudra renforcer les connaissances et les pratiques des MG par la promotion de la formation initiale et continue sur le dépistage. PMID:27800098

  13. Le cancer en Mauritanie : résultats sur 10 ans du registre hospitalier de Nouakchott

    PubMed Central

    Baba, Nacer Dine Ould Mohamed; Sauvaget, Catherine

    2013-01-01

    Le fardeau du cancer reste mal connu en Mauritanie. Il n'est basé que sur des extrapolations de l'incidence des cancers des pays avoisinants. Les données du registre de l'hôpital national permettent de décrire les cas avec un diagnostic histologique. Tous les cas de cancers enregistrés par le service d'anatomo-pathologie de l'hôpital national de Nouakchott de 2000 à 2009 ont été analysés. En 10 ans, 3305 prélèvements histologiques ont été analysés (hommes:42%, femmes:58%). Chez l'homme, le cancer le plus fréquemment analysé était le cancer de la peau (218 cas au total, 189 cas en excluant mélanome), suivi de la prostate (203), des cancers digestifs (179, colorectal et ‘sophage), et des lymphomes (151). Chez la femme, un quart des biopsies était des cancers du sein (485), suivi du col utérin (344), de la sphère gynécologique (218, ovaire et corps utérin), et de la peau (114). Les cancers du foie, du poumon ou de la vessie étaient peu fréquents. Ces résultats ne reflètent pas l'incidence ni l'actuel fardeau du cancer en Mauritanie puisque de nombreux patients diagnostiqués avec un cancer ne reçoivent pas d'examen anatomopathologique. Si, comme dans les pays avoisinants du Maroc et du Mali, les cancers du col et du sein sont les pathologies les plus fréquentes chez la femme, la distribution des cancers chez l'homme dans ce registre hospitalier diffère des résultats des registres de population du Maroc et du Mali où les cancers du poumon, du foie, de la prostate et de la vessie dominent.

  14. The CEO's second act.

    PubMed

    Nadler, David A

    2007-01-01

    When a CEO leaves because of performance problems, the company typically recruits someone thought to be better equipped to fix what the departing executive couldn't--or wouldn't. The board places its confidence in the new person because of the present dilemma's similarity to some previous challenge that he or she dealt with successfully. But familiar problems are inevitably succeeded by less familiar ones, for which the specially selected CEO is not quite so qualified. More often than not, the experiences, skills, and temperament that yielded triumph in Act I turn out to be unequal to Act II's difficulties. In fact, the approaches that worked so brilliantly in Act I may be the very opposite of what is needed in Act II. The CEO has four choices: refuse to change, in which case he or she will be replaced; realize that the next act requires new skills and learn them; downsize or circumscribe his or her role to compensate for deficiencies; or line up a successor who is qualified to fill a role to which the incumbent's skills and interests are no longer suited. Hewlett-Packard's Carly Fiorina exemplifies the first alternative; Merrill Lynch's Stanley O'Neal the second; Google's Sergey Brin and Larry Page the third; and Quest Diagnostics' Ken Freeman the fourth. All but the first option are reasonable responses to the challenges presented in the second acts of most CEOs' tenures. And all but the first require a power of observation, a propensity for introspection, and a strain of humility that are rare in the ranks of the very people who need those qualities most. There are four essential steps executives can take to discern that they have entered new territory and to respond accordingly: recognition that their leadership style and approach are no longer working; acceptance of others' advice on why performance is faltering; analysis and understanding of the nature of the Act II shift; and, finally, decision and action.

  15. The ACTS multibeam antenna

    Regier, Frank A.

    1992-01-01

    The Advanced Communications Technology Satellite (ACTS) to be launched in 1993 is briefly introduced. Its multibeam antenna, consisting of electrically similar 30 GHz receive and 20 GHz transmit offset Cassegrain systems, both utilizing orthogonal polarizations, is described. Dual polarization is achieved by using one feed assembly for each polarization in conjunction with nested front and back subreflectors, the gridded front subreflector acting as a window for one polarization and a reflector for the other. The antennas produce spot beams with approximately 0.3 degree beamwidth and gains of approximately 50 dbi. High surface accuracy and high edge taper produce low sidelobe levels and high cross-polarization isolation. A brief description is given of several Ka-band components fabricated for ACTS. These include multiflare antenna feedhorns, beam-forming networks utilizing latching ferrite waveguide switches, a 30 GHz HEMT low-noise amplifier and a 20 GHz TWT power amplifier.

    The U.S. Army Topographic Engineering Center, concerned about frequency license problems inherent with operating data-ready radios to support differential GPS (DGPS), learned of an experiment program the National Aeronautics and Space Administration (NASA) was sponsoring with its prototype digital satellite - the Advanced Communications Technology Satellite (ACTS). ACTS was designed to evaluate many new, untested technologies for eventual transfer to U.S. telecommunications and related industries. The new technologies promised greater data transmission rates and significantly reduced transmission latency. recognizing these benefits, the Topographic Engineering Center designed a DGPS experiment using an ACTS datalink with baselines of 200 kilometers and longer to learn what positional accuracy was possible with leading-edge satellite telecommunications technology.

    Summary Les brûlures électriques par haut voltage sont responsables de gros dégâts tissulaires en immédiat et dans les jours suivant l’accident du fait de la chaleur importante dégagée par effet joule et de la thrombose microvasculaire évolutive. Les pertes de substances du scalp secondaires à ces brûlures nécessitent une couverture par lambeaux vu la destruction du périoste et du calvarium en regard. De juin 1997 à juin 2008, 15 patients ont été traités pour des pertes de substance du scalp secondaires à des brûlures électriques par haut voltage de diamètre allant de 8 à 11 cm et siégeant dans la région tonsurale. Ces patients ont été opérés dans la première semaine suivant l’accident. Les pertes de substance du scalp de taille moyenne secondaires à ces brûlures peuvent être couvertes per primam de façon fiable par des lambeaux locaux axialisés et multiples. Nous relatons l’expérience du Service de Chirurgie Plastique du Centre Hospitalier Universitaire Ibn-Sina, Rabat, Maroc, dans la gestion et la prise en charge de ces brûlures. PMID:22262963

    2015-12-16

    The advantage of using depleted uranium (DU) hohlraums in high-yield deuterium-tritium (DT) shots at the National Ignition Facility (NIF) is addressed by Döppner, et al., in great detail [1]. This DU based hohlraum incorporates a thin layer of DU, ~7 μm thick, on the inner surface along with a thin layer of a gold coating, ~0.7 μm thick, while the outer layer is ~22 μm thick gold. A thickness measurement of the DU layer can be performed using an optical microscope where the total DU weight can be computed provided a uniform DU layer. However, the uniformity of the thickness is not constant throughout the hohlraum since CAD drawing calculations of the DU weight do not agree with the computed values from optical measurements [2]. Therefore, a non-destructive method for quantifying the DU content in hohlraums has been established by utilizing gamma-ray spectroscopy. The details of this method, along with results from several hohlraums, are presented in this report.

    The symptom commonly associated with whole body irradiation is diarrhoea, a still quite obscure phenomenon, which leads to decreased chance of cure of irradiated people. The aim of this study was to provide evidence for dysfunction of intestinal water and electrolyte transport regulation by the enteric nervous system after exposure to ionising radiation. This study shows decreased capacity of enteric nervous system to influence colonic transport 3days after irradiation, correlated to a diminished response to a neurotransmitter: serotonin. Radio-induced diarrhea may result from epithelial structural injury but also from impaired regulatory processes of intestinal transport. L'un des symptômes majeurs d'une irradiation corporelle totale ou abdominale est l'apparition de diarrhées, dont les causes sont encore mal connues, et qui mettent en jeu le pronostique vital de l'individu irradié. Cette étude vise à mettre en évidence l'atteinte de la régulation du transport intestinal d'eau et d'électrolytes par les rayonnements ionisants. On observe une diminution de la capacité du système nerveux entérique à influencer le transport colique 3jours après irradiation, corrélée à une diminution de la réponse épithéliale à un neurotransmetteur : la sérotonine. Les diarrhées radio-induites résulteraient d'une atteinte structurelle de l'épithélium mais également des processus de régulation du transport intestinal.

    Les travaux de recherche de cette these de doctorat ont porte sur les phenomenes d'incompatibilite (ou de compatibilite) ciment/adjuvant dispersant en mettant l'accent sur l'influence du mode d'introduction des adjuvants sur les proprietes des betons frais et durcis. Les aspects physiques et chimiques de l'interaction ciment/adjuvant a ete relies aux proprietes des betons en tenant compte du rapport E/C, de la teneur en C3A du ciment ainsi que du type d'adjuvant dispersant. Le programme experimental propose debute par une etude rheologique et mecanique sur pate et sur beton. Le comportement du superplastifiant a base de polynaphtalene (PNS) depend surtout de son interaction avec les premiers produits d'hydratation du ciment. Cette interaction du superplastifiant PNS avec le ciment est remarquablement differente dans le cas ou l'ajout du PNS est differe de quelques minutes. Lorsque le superplastifiant PNS est introduit directement avec l'eau de gachage, on remarque la formation d'un gel blanc compose d'ettringite, de CaCO 3 et de polynaphtalene et ce compose organo-mineral est presque inexistant lorsque le superplastifiant PNS est ajoute en mode differe. Ce gel organo-mineral se forme a partir de la solution entre les aluminates de calcium hydrates, les sulfates et le PNS, et est responsable de la perte d'affaissement du beton. Les analyses au microscope electronique a balayage montrent que l'introduction du superplastifiant PNS en mode S1 (ajout direct) engendre la precipitation d'une plus grande quantite d'ettringite et de produit organo-mineral. Cette ettringite finement cristallisee, abondante et enchevetree aura pour consequence de diminuer les proprietes rheologiques des betons et des pates. Ce phenomene ne s'observe pas lorsque le superplastifiant PNS est introduit en mode differe. Le mode d'introduction du superplastifiant a base de polyacrylate (PAE) n'affecte nullement le comportement rheologique du beton. Par ailleurs, le gel organo-mineral n'apparait pas

    The Patient Protection and Affordable Care Act of 2010 (PPACA), although a subject of much debate in the Unites States, was enacted on March 23, 2010, and upheld by the Supreme Court on June 28, 2012. This act advocates that "healthcare is a right, not a privilege." The main goals of PPACA are to minimize the number of uninsured Americans and make healthcare available to everyone at an affordable price. The Congressional Budget Office has determined that 94% of Americans will have healthcare coverage while staying under the $900 billion limit that President Barack Obama established by bending the healthcare cost curve and reducing the deficit over the next 10 years.

    2010-11-01

    Depleted uranium (DU) particles were isolated from soils at Eskmeals, UK, where DU munitions have been tested against hard targets and unfired DU buried in soils for corrosion studies. Using electron microscopy and X-ray analyses, three classes of particles were identified: (1) DU aerosols and fragments, typically 1-20 μm diameter, composed mainly of uranium as UO(2) and U(3)O(8), (2) solidified molten particles, typically 200-500 μm diameter, composed of U, mixed with Fe from target materials and (3) deposits and coatings, often of metaschoepite on sand grains up to 500 μm diameter. The first two particle types are derived from firing impacts, the last from corrosion of buried uranium metal. Alpha and mass spectrometry allowed quantitative elemental and isotopic characterisation of DU-containing particulate environmental samples. Copyright © 2010 Elsevier B.V. All rights reserved.

  15. Quantification du champ electromagnetique et description quantique de la generation du second harmonique a l'interieur d'une microcavite

    NASA Astrophysics Data System (ADS)

    Collette, Marc

    L'existence de particules virtuelles qui surgissent spontanement du vide pour disparaitre tres peu de temps apres leur apparition (les fluctuations du vide) trouve son origine dans le principe d'incertitude de Heisenberg. Par ailleurs, on sait que le phenomene de resonance par confinement explique l'amplification de l'intensite lumineuse a l'interieur d'une cavite ouverte aux frequences de resonances de celle-ci. C'est pourquoi le taux d'apparition des photons virtuels au sein des modes propres d'une cavite est lui aussi amplifie par le resonateur. Mathematiquement, cet effet quantique est decrit par l'existence d'un commutateur " anomal " entre les operateurs d'annihilation et de creation des photons. Nous decrivons les consequences de ce commutateur sur la generation du second harmonique optique (GSH), un processus photonique ou, dans un materiau optiquement non lineaire, deux photons de meme energie fusionnent pour n'en former qu'un seul. On commence ce travail avec un traitement complet et original sur la quantification du champ electromagnetique. On montre ensuite que les fluctuations du vide stimulent le signal de la GSH a l'interieur du milieu confine. Cependant, on constate aussi que les fluctuations du vide jouent le role d'un inhibiteur au declenchement du processus, c'est-a-dire que le seuil de la GSH augmente (il est superieur au seuil minimal de deux photons seulement). En conclusion, les mecanismes intimes de certains processus optiques non lineaires doivent etre reconsideres lorsqu'ils surviennent en presence d'un confinement electromagnetique.

    Scaling glomerular filtration rate (GFR) to body surface area (BSA) has been widely accepted, and was debated in recent years. Although the indexation ability of BSA is inferior to other physiological variables, the evaluation of BSA formulae is still meaningful to clinical practice. In this study, to evaluate the indexation ability of BSA formulae, the repeated measures analyses of camerabased scintigraphy (Gates method, gGFR) and plasma-based clearance (pGFR) were used to specially focus on the between-subjects variability that tried to be minimized by GFR normalization. The patients, who were older than 18 y and suffered from renal diseases, were enrolled and grouped according to the Chinese BMI (body mass index) criteria. All patients accepted renal scintigraphy and plasma clearance examinations. The gGFR and pGFR were separately scaled to DuBois&DuBois, Boyd, Stevenson, Gehan, Haycock, Mosteller, Hu and Livingston and Lee's formula. In the repeated measures analyses, the intraclass correlation coefficient (ICC), concordance correlation coefficient (CCC) and the ratio of residual standard deviation to pooled standard deviation (RSD/PSD) were used for the evaluation. During January 2010 and May 2012, 220 patients were enrolled. The evaluated BSA formulae had well correlated results and significant differences among BMI groups. From high to low, the sequence of the correlation between BMI and BSA formula was LL, Haycock, Gehan, Boyd, Mosteller, Stevenson, Hu and DuBois&DuBois formula. Both the scaled indices (ICC and CCC) and RSD/PSD indicated that, the sequence of indexation ability of BSA equations was Livingston< Haycock< Gehan< Stevenson< Mosteller< Boyd< Hu < DuBois&DuBois. Among the evaluated BSA formulae, DuBois&DuBois formula correlates to BMI the worst, and has the best indexation ability in scaling GFR of adult renal patients.

    The solar system's most scientifically tantalizing terrain remains out of reach for traditional planetary rovers, which are typically limited to driving on slopes below 30 degrees. This paper details the design of a novel robotic explorer that would open access to these previously inaccessible locales, such as Martian crater walls where evidence of salty water was recently detected, Lunar polar craters where evidence of water ice was detected, and Lunar and Martian lava tubes for future habitability. The Axel rover is a two-wheeled robot capable of rappelling down steep (even vertical) slopes supported by a tether. The DuAxel rover is comprised of two Axel vehicles docked to a central module. Unrestricted by tether length, this four-wheeled system would be capable of driving long distances from a safe landing zone to the extreme terrain of interest. Once in the vicinity of terrain in which the tether would be required, one of the Axel rovers could undock from the central chassis and rappel downslope. The other Axel and central chassis would remain topside to act as an anchor and to provide line of site to Earth (for communications) and the Sun (for energy). As the detached Axel descends into the area of interest, it would receive power and relays data through conductors in its tether. Each Axel would carry a suite of instruments in a bay that would be tucked inside the wheels. Because of the novel configuration of Axel's major degrees of freedom, these instruments could be precisely pointed at targets at any desired downslope spatial separation. These instruments could then be deployed into close proximately to the ground by means of a simple mechanism, allowing for detailed study of the strata on the slope. Axel could accommodate a host of instruments, including a microscopic imager, infra-red spectrometers, thermal probes, and sample collection devices. This paper will describe the design of both the latest generation of Axel and DuAxel systems and their

    Introduction Le streptocoque du groupe B est le principal agent impliqué dans les infections materno-fœtales, les septicémies et les méningites du nouveau-né à terme. L'objectif est de déterminer le taux de portage maternel du streptocoque du groupe B (SGB) à terme. Méthodes Un prélèvement vaginal a été réalisé de manière prospective chez 275 parturientes lors de l'entrée en salle d'accouchement sur une période de 06 mois. Résultats Le taux de portage était de 20,2%. Le portage était variable en fonction de l’âge gestationnel, il constitue 57.5% entre 37 et 38 semaines d'aménorrhée. Aucun des facteurs de risque n'a était statistiquement prédictif du portage maternel du SGB. Conclusion Le dépistage doit être réalisé à partir de 37 semaines d'aménorrhée, et comme le portage est intermittent, un prélèvement négatif ne garantirait pas que le portage soit négatif à l'accouchement.

  20. Properties, use and health effects of depleted uranium (DU): a general overview.

    PubMed

    Bleise, A; Danesi, P R; Burkart, W

    2003-01-01

    Depleted uranium (DU), a waste product of uranium enrichment, has several civilian and military applications. It was used as armor-piercing ammunition in international military conflicts and was claimed to contribute to health problems, known as the Gulf War Syndrome and recently as the Balkan Syndrome. This led to renewed efforts to assess the environmental consequences and the health impact of the use of DU. The radiological and chemical properties of DU can be compared to those of natural uranium, which is ubiquitously present in soil at a typical concentration of 3 mg/kg. Natural uranium has the same chemotoxicity, but its radiotoxicity is 60% higher. Due to the low specific radioactivity and the dominance of alpha-radiation no acute risk is attributed to external exposure to DU. The major risk is DU dust, generated when DU ammunition hits hard targets. Depending on aerosol speciation, inhalation may lead to a protracted exposure of the lung and other organs. After deposition on the ground, resuspension can take place if the DU containing particle size is sufficiently small. However, transfer to drinking water or locally produced food has little potential to lead to significant exposures to DU. Since poor solubility of uranium compounds and lack of information on speciation precludes the use of radioecological models for exposure assessment, biomonitoring has to be used for assessing exposed persons. Urine, feces, hair and nails record recent exposures to DU. With the exception of crews of military vehicles having been hit by DU penetrators, no body burdens above the range of values for natural uranium have been found. Therefore, observable health effects are not expected and residual cancer risk estimates have to be based on theoretical considerations. They appear to be very minor for all post-conflict situations, i.e. a fraction of those expected from natural radiation.

    The US Naval Observatory has completed the compilation of the ACT Reference Catalog, containing 988,758 stars covering the entire sky. The motivation behind the ACT was to provide accurate proper motions for the majority of the stars in the Tycho Catalogue. To do this, positions from new reductions of the Astrographic Catalogue (AC 2000) were combined with those of the Tycho Catalogue. The large epoch span between the two catalogs yields proper motions about an order of magnitude more accurate than those found in the Tycho Catalogue. The astrometric data contained in the ACT Reference Catalog include positions and proper motions and their corresponding errors. These are on the Hipparcos system (ICRS) for epoch J2000.0. Photometric and variability data from Tycho are included. In addition, cross-references to the Tycho, AC 2000, Bonner Durchmusterung (BD), Cordoba Durchmusterung (CD), Cape Durchmusterung (CPD), Henry Draper (HD), and Hipparcos catalogs are given. The ACT is now available at the international data centers and by contacting the authors via electronic mail.

    We report a documented case in Senegal with cri-du-chat syndrome diagnosed in a 3 months old girl. Our patient benefited from clinical examination, ECG (15 derivations), chest X ray and standard laboratory tests. The cry has been recorded on a magnetic band. We performed also a pulsed-Doppler, two dimensional and TM echocardiography. Chromosomal analysis has been realized. These data are discussed and compared to the literature. At admission this patient presents characteristic cat like cry. At examination, there is a facial dysmorphy, important growth retardation and feeding dyspnea. Auscultation shows a 3/6 left sub-clavicular systolic murmur. Laboratory tests show anemia (hemoglobin = 7.8 g/dl). Chest x-ray showed a cardio-thoracic ratio at 0.61 with increased pulmonary vascular markings. ECG showed right ventricular hypertrophy. Echocardiography-Doppler revealed persistent ductus arteriosus (PDA). Chromosomal analysis shows deletion of the short arm of chromosome 5. After treatment with digitalis and diuretics there was an improvement of cardiac failure. Diagnosis of cri-du-chat syndrome is easy when characteristic cat-like-cry is present. Cardiovascular abnormalities are unfrequent in this syndrome (20% of the cases). They are dominated by ventricular septal defect and PDA. Hemodynamic failure and related growth retardation can lead to cardiac surgery.

    Les cancers du sein bilatéraux synchrones (CSBS) sont des maladies qui se caractérisent par une importante hétérogénéité clinique et morphologique avec une fréquence entre 1,5 et 3,2%. Les femmes traitées pour un cancer du sein unilatéral sont à haut risque de développer un cancer au niveau controlatéral. Le dépistage et les progrès de l’imagerie mammaire ont permis une augmentation de découverte des CSBS. L’objectif de notre travail est d’étudier les caractéristiques épidémiologiques, cliniques, histologiques, et thérapeutiques du cancer du sein bilatéral. Il s’agit d’une étude transversale étalée sur deux années des patientes prise en charge au centre Mohammed VI pour le traitement des cancers. L’analyse statistique des résultats a été réalisée par le logiciel R. 31 patientes ont présenté un CSBS, représentant 2,4% des cas du cancer du sein dans notre Centre. L’âge moyen était 47,8 ± 8,4 ans, 22,6% utilisaient des contraceptifs oraux. Une histoire familiale de cancer du sein était observée dans 22,6% des cas. Le type histologique le plus fréquent était le carcinome canalaire infiltrant (58,1%), Le grade SBR II et III étaient fréquents (38,7%). Les récepteurs hormonaux entaient positifs, aux progestérones (38,7%) et aux œstrogènes (41,9%). Le récepteur HER2 était surexprimé dans 20,0% des cas. 29,0% des cas ont bénéficié d’une hormonothérapie et 3,2% de thérapies ciblées. Notre étude a montré que le cancer du sein bilatéral représente une proportion faible, mais avec certaines particularités cliniques, différant du cancer du sein unilatéral. PMID:28292084

Les annees 1948 a 1955 (troisieme partie de these) correspondent a une periode de croissance pour le mouvement cooperatif. Cette partie scrute ainsi le developpement des cooperatives, les vastes chantiers de construction et l'injection de millions de dollars dans l'electrification rurale. Cette troisieme partie prend egalement acte des premiers signes que quelque chose ne va pas si bien dans le monde cooperatif. Nous y verrons egalement les ruraux a l'oeuvre: comme membres, d'abord, mais aussi en tant que benevoles, puis a l'emploi des cooperatives. La quatrieme et derniere partie, les annees 1956 a 1964, aborde les changements majeurs qui ont cours dans l'univers cooperatif; il s'agit d'une ere nouvelle et difficile pour le mouvement cooperatif, dont les reseaux paraissent inadaptes aux changements de profil de la consommation d'electricite des usagers. L'OER sent alors le besoin de raffermir son controle des cooperatives, car il pressent les problemes et les defis auxquels elles auront a faire face. Notre etude se termine par l'acquisition des cooperatives par Hydro-Quebec, en 1963-64. Fondee sur des sources riches et variees, notre demarche propose un eclairage inedit sur une dimension importante de l'histoire de l'electricite au Quebec. Elle permet, ce faisant, de saisir les rouages et l'action de l'Etat sous un angle particulier, avant sa profonde transformation amorcee au cours des annees 1960. De meme, elle apporte quelques cles nouvelles pour une meilleure comprehension de la dynamique des milieux ruraux de cette periode.

  1. Le role du phytoplancton de petite taille (<20 mum) dans les variations des proprietes optiques des eaux du Saint-Laurent

    NASA Astrophysics Data System (ADS)

    Mas, Sebastien

    Les mesures satellitaires de couleur des oceans sont largement determinees par les proprietes optiques inherentes (IOPs) des eaux de surface. D'autre part, le phytoplancton de petite taille (<20 mum) est le plus souvent dominant dans les oceans, et peut donc etre une source importante de variation des IOPs dans les oceans. Dans ce contexte, le but principal de ce doctorat etait de definir l'impact du phytoplancton (<20 mum) sur les variations des proprietes optiques de l'Estuaire et du Golfe du Saint-Laurent (Canada). Afin d'atteindre cet objectif, il etait necessaire de determiner en milieu controle les facteurs de variabilite des proprietes optiques cellulaires et des IOPs du phytoplancton (<20 mum) des eaux du Saint-Laurent, et d'evaluer la contribution du phytoplancton (<20 mum) aux proprietes optiques totales des eaux du Saint-Laurent. Des experiences en laboratoire ont montre que les variations des proprietes optiques des cellules phytoplanctoniques soumises a un cycle jour-nuit, ainsi qu'a des changements concomitants d'intensite lumineuse, peuvent contribuer significativement a la variabilite des proprietes optiques observee en milieu naturel. D'autres experiences ont, quant a elles, mis en evidence que les variations des proprietes optiques des cellules phytoplanctoniques dues aux phases de croissance peuvent alterer les IOPs des oceans, particulierement pendant les periodes de floraison. De plus, la presence de bacteries et de particules detritiques peut egalement affecter la variabilite des IOPs totales, notamment la diffusion. Au printemps, dans l'Estuaire et le Golfe du Saint-Laurent, la contribution du phytoplancton <20 mum aux IOPs presentait des differences regionales evidentes pour les proprietes d'absorption et de diffusion. En plus de la variabilite spatiale, les proprietes optiques cellulaires presentaient des variations journalieres, et ce particulierement pour le picophytoplancton. Enfin, la plupart des differences observees dans les

Because it affects few people in the population it is considered a rare disease, yet it is one of the most common autosomal chromosomal syndromes in humans. It entails pathognomonic alterations that affect the craniofacial and oral anatomy of patients. The aim of this study is to review these craniofacial and oral abnormalities in patients with Cri du chat syndrome. The PubMed Medline database was searched using two different strategies. First, we used "Dentistry" and "Cri du chat" as keywords; second, we used "Cri du chat" and "craniofacial." Seven articles in which the main orofacial and cranio-skeletal characteristics of patients with Cri du chat syndrome were described were selected according to the inclusion and exclusion criteria. Cri du Chat syndrome entails pathognomonic characteristics in the craniofacial area (epicanthus, short philtrum, and wide nasal bridge), the oral area (mandibular retrognathism and anterior open bite) and the cranial region (alterations at the cranial base angle and a small upper airway). However, more studies on larger samples are needed to specify the orofacial and craniofacial characteristics of patients with Cri du chat syndrome more accurately. Clin.

    L'association d'une communication interventriculaire post infarctus du myocarde et d'un anévrysme du ventricule gauche chez un même patient est extrêmement rare et survient habituellement durant la première semaine qui suit un infarctus du myocarde. Nous rapportons le cas insolite d'un patient âgé de 63 ans, admis pour choc cardiogénique en rapport avec une communication inter ventriculaire apicale et un anévrysme ventriculaire gauche causés par un infarctus du myocarde antérieur. La correction chirurgicale a consisté en une fermeture du défect septal par un patch en dacron via une ventriculotomie gauche associée à une anévrysectomie et un mono pontage coronaire. Cette observation illustre d'une part la rareté de l'association communication inter ventriculaire-anévrysme ventriculaire gauche post infarctus du myocarde, et d'autre part l'efficacité du traitement chirurgical qui reste la seule option salvatrice pour cette pathologie.

    All of the 4000 infants who die daily in India have been bottle fed. Most of these infants die from infections which are typically caused by bottle feeding. Considerable research has shown that human breast milk ideally suits babies' needs. Human breast milk protects infants from several infections and allergies, such that the breastfed infant is 25 times less likely than the bottle fed infant to die due to diarrhea and pneumonia. Comparative studies have even found breastfed babies to have higher IQs than bottle fed ones. Detrimental maternity home practices, adverse social factors, and the unethical and aggressive marketing strategy adopted by the manufacturers of infant milk substitutes and feeding bottles are the major factors responsible for the erosion of the practice of breastfeeding. These factors are discussed. The Infant Milk Substitutes, Feeding Bottles, and Infant Foods Act prohibits the advertisement and promotion of feeding bottles and infant milk substitutes by unethical marketing strategies. Violations of the act are punishable by imprisonment and a heavy fine. The act and the need for its passage are discussed.

    The Advanced Communications Technology Satellite (ACTS) to be launched in 1993 introduces several new technologies including a multibeam antenna (MBA) operating at Ka-band. The satellite is introduced briefly, and then the MBA, consisting of electrically similar 30 GHz received and 20 GHz transmit offset Cassegrain systems utilizing orthogonal linear polarizations, is described. Dual polarization is achieved by using one feed assembly for each polarization in conjunction with nested front and back subreflectors, the gridded front subreflector acting as a window for one polarization and a reflector for the other. The antennas produce spot beams with approximately 0.3 deg beamwidth and gains of approximately 50 dbi. High surface accuracy and high edge taper produce low sidelobe levels and high cross-polarization isolation. A brief description is given of several Ka-band components fabricated for ACTS. These include multiflare antenna feedhorns, beam-forming networks utilizing latching ferrite waveguide switches, a 30 GHz high mobility electron transmitter (HEMT) low-noise amplifier and a 20 GHz TWT power amplifier.

    Introduction Les traumatismes du colon sont associés à un risque majeur de complications septiques et de mortalité. Le but de notre étude est d’évaluer les circonstances, la prise en charge, le suivi et les facteurs pronostic de morbidité postopératoire des malades victimes d'un traumatisme colique. Méthodes Il s'agit d'une étude rétrospective sur une série de 49 patients opérés pour des plaies coliques aux services de chirurgie viscérale du CHU HASSAN II de Fès sur une période de 8 ans de juillet 2003 à juillet 2011. Résultats L’âge moyen de nos patients était de 25ans (16-70) avec une nette prédominance masculine (93.8%). Les plaies coliques secondaires à un traumatisme par arme blanche représentent 85% des cas (42 patients), suivi par les plaies iatrogènes au cours d'une coloscopie chez 6 patients (13%), puis les contusions abdominales chez 1 patient (2%). Les parties du cadre colique les plus touchées étaient le colon transverse chez 19 patients (38%) et le colon descendant chez 12 patients (24, 5%). Le colon sigmoïde était le segment le plus touché au cours d'une coloscopie4/6. Quarante-deux patients (85%) ont eu une suture primaire des plaies coliques, six patients (13%) une diversion fécale et un patient (2%) une résection-anastomose. Deux patients (4%) sont décédés suite à un choc septique. La morbidité globale était de 38,7% dominé essentiellement par l'infection de la paroi chez 14 patients et une péritonite post opératoire chez 3 patients. L'analyse univarié a montré une différence significatif en terme d'infection de la paroi entre le groupe colostomie versus suture simple (50% vs 20,9% p<0,05). L'atteinte du colon gauche et la réalisation d'une colostomie sont associés à un risque plus élevés de complications postopératoires. Conclusion La suture primaire peut être effectuée avec un faible taux de complications postopératoire chez la majorité des patients suite à un traumatisme du colon. PMID

    Le syndrome du Cri du Chat (Cri du Chat syndrome, CdCS) est une anomalie chromosomique résultant d’une délétion de taille variable de l’extrémité du bras court du chromosome 5 (5p), incluant une région critique située en p15.2. Il représente une des délétions chromosomiques les plus fréquentes, son incidence dans la population générale est de 1/20 000 à 1/50 000. Les caractéristiques cliniques comprennent un cri monochromatique aigu, une microcéphalie, une dysmorphie cranio-faciale caractéristique évoluant avec l’âge et un retard mental et psychomoteur important. La taille de la délétion est variable, Le traitement est fonction des différents symptômes. Un remaniement chromosomique parental est retrouvé dans 12% des cas et la majorité des délétions responsables de la maladie du cri-du-chat surviennent de novo. Nous présentons une observation d’un syndrome du Cri du Chat, confirmé par caryotype métaphasique (46,XY,del(5)(p13) de novo). A travers cette observation nous mettrons à jour, les actualités scientifiques de ce rare syndrome, ainsi que la place des explorations cytogénétiques dans le diagnostic précis et le conseil génétique des syndromes dysmorphiques.

    Des cellules réticulaires remplies de molécules de ferritine et d'hémosidérine se trouvent au centre "d'ilots érythroblastiques." Dans la zone de contact entre la cellule réticulaire chargée de ferritine et les érythroblastes, on voit des invaginations et des petites vacuoles au bord desquelles adhérent des molécules de ferritine. Il est postulé que la ferritine passe de la cellule réticulaire centrale dans les érythroblastes par ce mécanisme, apparenté à la pinocytose (rhophéocytose). Dans tous les érythroblastes normaux, il existe du fer sous forme de ferritine. Celle-ci peut se trouver à l'état dispersé ou agglomérée en amas. Lorsque ces amas sont assez gros, ils sont visibles au microscope optique: ce sont les granules des sidéroblastes. On trouve du fer dans les mitochondries, mais rarement à l'état normal. Il est soit sous forme de granules ferritiniques soit sous forme de micelles ferrugineuses. Dans les thalassémies et d'autres maladies s'accompagnant d'un trouble de l'hémoglobinogénèse, on trouve, en grande quantité, du fer visible au microscope électronique, dans les érythroblastes. Il s'y trouve sous forme de ferritine, en amas ou dispersé. Il existe parfois en grande quantité dans les mitochondries soit sous forme de ferritine, soit sous forme de micelles ferrugineuses. Il semble que soit objectivé ainsi le trouble de la synthèse de l'hémoglobine: le fer inutilisé s'accumule dans des érythroblastes hypochromes. Il est probable qu'à l'etat normal, le fer est métabolisé dans les mitochondries. Dans le thalassémies et les anémies hypochromes hypersidérémiques, il semble souvent bloqué dans ces organites.

Méthodes Le génotype de l'apo E a été analysé par séquençage direct chez 46 patients cliniquement diagnostiqués ADH selon les critères standards. Résultats Les fréquences des allèles epsilon 3, epsilon 2 et epsilon 4 ont été respectivement 78.3%, 2.2% et 19.6%. La fréquence de l'allèle epsilon 4 est très élevée chez la population du nord du Maroc en comparaison avec les populations des autres régions marocaines. Elle est similaire à celle rapportée dans les pays de l'Europe du nord. Les taux du cholestérol total, du cholestérol LDL ainsi que la présence des xanthomes et les maladies cardiovasculaires ne différent pas entre les génotypes de l'apoE. En revanche, les résultats ont montré une influence de l'allèle epsilon4 sur le taux des triglycérides chez les sujets obèses. Conclusion Le génotype de l'apoE ne peut expliquer le phénotype clinique et biochimique présenté par des patients du Nord du Maroc cliniquement diagnostiqués ADH. PMID:24396563

    Levesque, Isabelle

    La synthese et la caracterisation de derives regioreguliers du polythiophene ont ete effectuees en solution et sur des films minces. La spectroscopie UV-visible de ces derives a permis de constater qu'ils peuvent posseder des proprietes chromiques particulieres selon le stimulus auquel ils sont soumis. Par exemple, une augmentation de la temperature permet en effet aux polymeres de passer d'une couleur violette a jaune, et ce, a l'etat solide aussi bien qu'en solution. Ces proprietes chromiques semblent regies par une transition conformationnelle (plane a non-plane) de la chaine principale. Ce travail avait pour but de mieux comprendre l'influence de l'organisation des chaines laterales sur les transitions chromiques. Deux derives synthetises possedant des chaines laterales sensibles aux cations alcalins se sont averes etre ionochromes en plus d'etre thermochromes. Il s'agit d'un polymere comportant des chaines laterales de type oligo(oxyethylene) et d'un autre comportant un groupement ether couronne specifique aux ions lithium. Les effets chromiques observes sont expliques par des interactions non-covalentes des cations avec les atomes d'oxygene des chaines laterales dans le cas du premier polymere, et par l'insertion de l'ion Li + dans la cavite de l'ether couronne dans le cas du second polymere. Ces interactions semblent provoquer une diminution de l'organisation induisant ainsi une torsion de la chaine principale. Les deux polymeres semblent specifiques a certains cations et pourraient donc servir comme detecteurs optiques. La specificite aux ions Li+ du second polymere pourrait aussi permettre la conduction ionique, en plus de la conductivite electronique caracteristique des polythiophenes, ce qui pourrait s'averer utile dans le cas de batteries legeres entierement faites de polymeres et de sels de lithium. D'autres derives comportant des chaines laterales de type azobenzene se sont averes etre photochromes en plus d'etre thermochromes. Le groupement lateral a

    Rare cancers are defined by an incidence less than 5/100,000, which means in France less than 3,000 new cases a year. They are difficult to diagnose, their physiopathology has led to new knowledge in cancer medicine. There is no large experience for their management, and they are not generally the subject of randomized trials to establish treatment strategy. Therefore they are often managed by suboptimal cares. Even individually rare cancers do not concern large populations, the number of patients suffering of rare cancer is important. This is the reason why the "Bulletin du cancer" will open a new section on rare cancers. This article aims to draw the context of such a decision, based on an effort to allow these patients to receive optimal management.

    It has been observed that persons with Cri du chat syndrome (CDCS) have poor language production. However, very few studies have addressed the question whether all aspects of language production are equally afflicted, or whether there are differences between for instance phonological and morphological abilities. The present study was aimed at investigating to what extent persons with CDCS inflect verbs, and, if so, which inflectional patterns in the target language they make use of, and further what kinds of inflectional errors they make. We compared the performance of three subjects (aged 11, 15 and 22) with CDCS on a past tense elicitation task. We found that all three subjects inflected verbs. The number of correct responses, however, varied from 28% to 53%. The majority of errors were over-generalizations, imitation of input, no response and substitution by semantically related verbs.

    2008-01-01

    This article reports on a longitudinal case study of consonant productions in one Norwegian girl with Cri du chat syndrome from age 4;6 to age 9;4. It was shown that she had many articulation errors throughout the period of observation. Furthermore, these errors were shown to fall into three main categories: (1) errors of differentiation and tuning, (2) errors of coordination and sequencing, and (3) missing gestures. Also, omissions of segments were reported to be frequent. In sum, the consonant productions by this girl were found to be both delayed and deviant, as compared to normally developing children. The number of errors, however, decreased as she grew older, resulting in more accurate renditions of the target words.

    This article focuses on consonant productions by a group of children with cri du chat syndrome (CdCS) and examines how various aspects of these productions contribute to these children's overall intelligibility. Eight children and adolescents with CdCS participated in the study, and the following four questions were addressed: (1) What are the characteristic features of the consonant inventories of the subjects in terms of size and types of consonants; (2) how do the subjects render the consonant phonemes of the target language; (3) to what degree do the subjects produce target-like words; and (4) what is the relationship between consonant production and intelligibility? For the majority of our subjects, we found low proportions of correctly produced consonants, small consonant inventories with several recurrent types of deviant consonants, inaccuracy in realization of target phonemes and variable similarity to target words, all of which may contribute to reduced intelligibility.

    The cri du chat syndrome (CdCS) is a chromosomal deletion syndrome associated with a partial deletion of the short (p) arm of chromosome 5. We describe five children who were diagnosed to have CdCS by conventional cytogenetic analysis. The deletion was at 5p15 in four patients, whereas the fifth had a larger, more proximal deletion at 5p14. Fluorescence in situ hybridization (FISH) analysis confirmed the deletion of the CdCS critical region at 5p15.2. All five children had global developmental delay and dysmorphism with microcephaly. The other clinical features were variable. Since the clinical diagnosis of CdCS may not always be evident because of the phenotypic heterogeneity, cytogenetic analysis is necessary to establish the diagnosis and confirm that the deletion involves the CdCS critical region. This will enable early intervention which plays an important role in improving the outcome.

    A deletion of the short arm of chromosome No. 5 has been termed the cri du chat (cat cry) syndrome. We report the first ophthalmologic examination of a newborn infant with this syndrome. Multiple ophthalmic abnormalities were found, including hypertelorism, telecanthus, epicanthal folds, antimongoloid palpebral fissures, exotropia, optic atrophy, and tortuosity of the retinal vasculature. It is of interest that these changes are congenital and present at birth, rather than developmental. Although such individuals are usually so severely mentally retarded that no ophthalmologic intervention is indicated, there are rare exceptions, and each case must be judged individually. Ten percent to 15% of these children inherit the chromosomal abnormality from phenotypically normal parents. Chromosomes from each parent should therefore be evaluated for the purposes of genetic counseling.

    1972-01-01

    An unusual case of the cri-du-chat syndrome is described in a 6½ year old boy, who, as well as attacks of stridor and choking, showed disorders of spatial perception and cerebellar signs in the form of nystagmus, clumsiness of the hands, and ataxia. Pyramidal signs were also present. He was only mildly retarded mentally. Psychological testing showed that he had a severe deficit for number processing, and also constructional apraxia. Surprisingly, his vocabulary was quite good, as was his reading capacity. Chromosome analysis showed a very small deletion of the short arm of the group B chromosome. In infancy this diagnosis may be suspected because of the high-pitched cry and attacks of stridor and choking. In late childhood, when the signs may be only of a neurological disorder, its recognition may be difficult without confirmation from chromosome studies. The neurological features of this disease are reviewed. Images PMID:5084140

    HISTORIQUE : La lombalgie chronique est une douleur lombaire persistante d’origine multifactorielle. Le niveau de douleur initial reste faiblement utilisé pour analyser et comparer les réponses des patients lombalgiques au programme de reconditionnement. OBJECTIFS : Apprécier et évaluer les réponses des sujets lombalgiques chroniques très douloureux à une prise en charge dynamique et intensive. MÉTHODOLOGIE : 144 sujets atteints de lombalgie chronique ont été inclus dans un programme de restauration fonctionnelle du rachis de 5 semaines. Les sujets ont été classés en deux groupes de niveau de douleur: un groupe atteint de douleur sévère (n = 28) et un groupe atteint de douleur légère à modérée (n = 106). L’ensemble des sujets ont bénéficié d’une prise en charge identique comprenant principalement de la kinésithérapie, de l’ergothérapie, du reconditionnement musculaire et cardio-vasculaire ainsi qu’un suivi psychologique. Les paramètres physiques (flexibilité, force musculaire) et psychologiques (qualité de vie) ont été mesurés avant (T0) et après le programme (T5sem). RÉSULTATS : L’ensemble des performances physiques et fonctionnelles des sujets très douloureux sont moins bonnes et le retentissement de la lombalgie sur la qualité de vie, pour ces mêmes sujets, est majoré à T0. Toutes les différences significatives constatées à T0 entre les deux groupes s’effacent à T5sem. CONCLUSIONS : Les sujets lombalgiques chroniques très douloureux répondent favorablement au programme dynamique et intensif. L’intensité douloureuse de la lombalgie n’aurait pas d’effet sur les réponses au programme. La restauration fonctionnelle du rachis apporterait aux sujets la possibilité de mieux gérer leur douleur quel que soit son niveau. PMID:25299476

    In the last decade, the demand for reliable data, voice, and video satellite communication links between aircraft and ground to improve air traffic control, airline management, and to meet the growing demand for passenger communications has increased significantly. It is expected that in the near future, the spectrum required for aeronautical communication services will grow significantly beyond that currently available at L-band. In anticipation of this, JPL is developing an experimental broadband aeronautical satellite communications system that will utilize NASA's Advanced Communications Technology Satellite (ACTS) as a satellite of opportunity and the technology developed under JPL's ACTS Mobile Terminal (AMT) Task to evaluate the feasibility of using K/Ka-band for these applications. The application of K/Ka-band for aeronautical satellite communications at cruise altitudes is particularly promising for several reasons: (1) the minimal amount of signal attenuation due to rain; (2) the reduced drag due to the smaller K/Ka-band antennas (as compared to the current L-band systems); and (3) the large amount of available bandwidth. The increased bandwidth available at these frequencies is expected to lead to significantly improved passenger communications - including full-duplex compressed video and multiple channel voice. A description of the proposed broadband experimental system will be presented including: (1) applications of K/Ka-band aeronautical satellite technology to U.S. industry; (2) the experiment objectives; (3) the experiment set-up; (4) experimental equipment description; and (5) industrial participation in the experiment and the benefits.

    Piceatannol has potent anti-inflammatory, immunomodulatory, anticancer and antiproliferative effects. However, little is known about the mechanism by which piceatannol inhibits invasion and metastasis. The aim of the current study was to investigate the effects of piceatannol on the expression of matrix metalloproteinase-9 (MMP-9) in DU145 human prostate cancer cells. The results revealed that MMP-9 activity was significantly increased in response to tumor necrosis factor-α (TNF-α). However, treatment with piceatannol reversed TNF-α- and MMP-9-induced gelatin zymography and its gene expression. In addition, a Matrigel invasion assay determined that piceatannol reduces the TNF-α-induced invasion of DU145 cells. Nuclear factor-κ B (NF-κB) is a significant transcription factor that regulates numerous genes involved in tumor cell invasion and metastasis. Therefore, whether piceatannol acts on NF-κB to regulate MMP-9 gene expression was analyzed. The results revealed that piceatannol attenuates MMP-9 gene expression via the suppression of NF-κB activity. Using a specific NF-κB inhibitor, pyrrolidine dithiocarbamate, it was confirmed that TNF-α-induced MMP-9 gene expression is primarily regulated by NF-κB activation. Piceatannol inhibited NF-κB activity by suppressing nuclear translocation of the NF-κB p65 and p50 subunits. Furthermore, TNF-α-induced Akt phosphorylation was significantly downregulated in the presence of piceatannol. The Akt inhibitor LY294002 caused a significant decrease in TNF-α-induced NF-κB activity and MMP-9 gene expression. Overall, these data suggest that piceatannol inhibits TNF-α-induced invasion by suppression of MMP-9 activation via the Akt-mediated NF-κB pathway in DU145 prostate cancer cells. PMID:23255946

    Introduction La taille du pénis constitue une préoccupation de beaucoup des gens actuellement et certains ne sont pas satisfaits de la dimension de leur pénis comme le montre l’étude de Tiggemann en 2008. Il existe relativement peu d'études sur le pénis en érection. Cela peut refléter les tabous culturels des chercheurs ou des médecins en interaction avec les hommes qui sont dans un état d’excitation sexuelle. Toutes fois, il est important pour les personnes qui annoncent des détails sur la taille du pénis d’annoncer d’abord les repères de la mesure du pénis puis ensuite donner les chiffres que proposent les chercheurs. Méthodes Notre enquête de type descriptif transversale s’est effectuée dans les deux grandes villes de la République Démocratique du Congo à savoir la ville de Kinshasa et la ville de Lubumbashi, pendant une période de deux ans soit de Mai 2014 à Mai 2016. Au total, 21 sources d’information ont constitué notre échantillon dont 8 à Kinshasa et 13 à Lubumbashi et nous avons trouvé cela suffisant car les sujets à caractère sexuel sont souvent rares chez nous. Les paramètres étudiés étaient: la nature de la source, la précision de la technique de la mesure, la présence de référence bibliographique, la longueur annoncée du pénis. Résultats La majorité des sources d’information sont faites des émissions de radio et de télévision (23,8%), ceci pourra s’expliquer par le fait que dans notre milieu il y a de plus en plus des chaines de radio et télévision et surtout dans les grandes villes. Concernant la précision de la technique de la mesure du pénis lors du partage du message sur la taille du pénis, l’étude nous montre que la majorité des sources d’information ne signale pas cela lorsqu’elles annoncent la taille du pénis au public soit 85,7%. Plusieurs sources ne déclarent pas les références bibliographiques (57,1%). Lorsqu’on regarde même les chiffres de la taille du p

    The fist step growth of MOCVD GaAs/ImP is studied using Transmission Electron Microscopy. We show that a complete coverage occurs for layers as thin as 65Å, grown at 450°C. When the thickness increases and after a 700°C annealing during 5mn, the layers are more relaxed and the planar defects density decreases clearly, but unfortunatly thick epilayers (550Å) are less smooth than thinner ones. So, the optimum epilayer thickness realising the compromise between complete surface substrate coverage, defect density and surface roughness was found to be in the order of 150Å. A partir d'observations directes par microscopie électronique en transmission de la première étape de la croissance de GaAs sur des substrats (001) d'InP par OMCVD, nous montrons qu'une couverture totale du substrat a lieu pour des couches de 65Å d'épaisseur, déposées à 450°C. Lorsque l'épaisseur de la précouche augmente (de 65 à 550Å) et après un recuit de 5mn à 700°C, la couche se relaxe de plus en plus et la densité des défauts plans diminue ; en revanche, la rugosité de la surface augmente parallèlement. Une précouche d'épaisseur de l'ordre de 150Å semble être la mieux adaptée pour réaliser le compromis entre la couverture du substrat, une faible densité de défauts et une bonne morphologie de la surface.

  2. Sur la reponse en frequence du tissu nerveux dans le cortex

    Bedard, Claude

    Dans cette These de Physique, nous avons etudie la dependance en frequence du champ electrique du tissu nerveux dans le cortex. Ce champ est aussi designe par "Local field Potential" LFP dans la litterature scientifique. Cette etude est fondee sur la theorie du champ electromagnetisme de Maxwell et sur de l'information tiree de la donne experimentale. Le resultat essentiel de cette These est que la grandeur enorme du temps de relaxation de Maxwell des membranes cellulaires semble etre la cause principale de la dependance en frequence des LFPs. Cette dependance en frequence causee par chaque membrane cellulaire est l'analogue d'un circuit RC ou la resistance R est la resistivite parallele d'une membrane cellulaire, et ou la capacite C est la permittivite electrique de la membrane. L'effet resultant d'un tres grand nombre de cellules donne un spectre de Fourier dont l'enveloppe est tres pres d'un signal en 1/f. Le modele physique propose dans cette These permet de lier les mesures prises a l'interieur d'une dendrite des variations de potentiel electrique a celles prises dans le liquide extracellulaire. De plus, cette These semble ouvrir la possibilite de mesurer le temps de relaxation de Maxwell des membranes cellulaires a l'aide de la mesure de la reponse en frequence du potentiel electrique extracellulaire (LFP). Enfin, cette These permet de lever le voile sur un sujet peu etudie, principalement en raison de la difficulte que represente l'etude des phenomenes electriques dans des milieux complexes comme les tissus vivants. En particulier, le probleme du filtrage frequentiel du potentiel electrique extracellulaire est une propriete fondamentale du tissu nerveux et son origine n'est pas connue.

    We have previously reported the potent in vitro HIV-1 anti-reverse transcriptase activity of a 35-mer of 4-thio-deoxyuridylate [(s(4)dU)(35)]. In efforts to define its activity in a more physiological system, studies were carried out to determine the stage of viral infection that this compound mediates its anti-viral effect. Results of the studies reported herein show that (s(4)dU)(35) is nontoxic and is capable of inhibiting both single and multi-drug resistant HIV strains (IC(50): 0.8-25.4 microg/ml) in vitro. Besides its previously reported anti-RT activity, (s(4)dU)(35) mediated its antiviral action by preventing virus attachment (IC(50): 0.002-0.003 microg/ml), and was stable in vitro and slowly degraded by DNAses. Competition studies and fluorescence resonance energy transfer (FRET) experiments indicated that (s(4)dU)(35) preferentially binds to CD4 receptors, but not to CD48. Confocal laser scanning microscopy (CLSM) studies showed that (s(4)dU)(35) did not penetrate into the cells and colocalized with cell surface thioredoxin. Our studies identify (s(4)dU)(35) as a potential novel HIV entry inhibitor that may have utility as either a systemic antiretroviral or as a preventing agent for HIV transmission.

    Une manière simple de caractériser l'avancement du frittage d'une poudre est de suivre ses variations de densité relative. Cependant, pour les poudres d'acier préalablement compactées en matrice, la densité initiale est grande, par conséquent évolue peu lors du frittage. Au contraire, la microstructure et les propriétés du matériau évoluent beaucoup. Dans cette étude, l'avancement du frittage est suivi in situ au cours du frittage par deux caractéristiques physiques : la résistivité électrique et la viscosité. Les techniques innovantes développées pour ces mesures expérimentales sont présentées ainsi que l'intérêt des résultats pour la compréhension et la modélisation du frittage.

    La rupture traumatique de la coupole diaphragmatique droite avec hernie du foie dans le thorax est une lésion rare. Elle est souvent intégrée dans le cadre d'un poly-traumatisme, dont elle est un critère de gravité. Elle expose, précocement ou tardivement, à des complications cardio-pulmonaires par compression. Le diagnostic d'une rupture diaphragmatique droite est difficile à établir. En effet, ses signes cliniques sont peu spécifiques et l'imagerie peut être prise en défaut du faite qu'elle visualise les organes ascensionnés mais plus difficilement la rupture elle-même. La voie d'abord thoracique est souvent préférée du fait des difficultés de l'exposition du diaphragme en présence du foie. Nous rapportons un cas d'une rupture diaphragmatique droite avec passage isolé et total du foie en intra-thoracique diagnostiquée au cinquième jour d'hospitalisation chez un polytraumatisé.

    Cri-du-chat is a chromosomal deletion syndrome characterized by partial deletion of the short arm of chromosome 5. The clinical symptoms include growth and mental retardation, microcephaly, hypertelorism, epicanthal folds, hypotonia, and a high-pitched monochromatic cry that is usually considered diagnostic for the syndrome. Recently, a correlation between clinical features and the extent of the chromosome 5 deletions has identified two regions of the short arm that appear to be critical for the abnormal development manifested in this syndrome. Loss of a small region in 5p15.2 correlates with all of the clinical features of cri-du-chat with the exception of the cat-like cry, which maps to 5p15.3. Here we report the construction of a YAC contig that spans the chromosomal region in 5p15.2 that plays a major role in the etiology of the cri-du-chat syndrome. YACs that span the 2-Mb cri-du-chat critical region have been identified and characterized. This YAC contig lays the groundwork for the construction of a transcriptional map of this region and the eventual identification of genes involved in the clinical features associated with the cri-du-chat syndrome. It also provides a new diagnostic tool for cri-du-chat in the shape of a YAC clone that may span the entire critical region.

The clinical symptoms include growth and mental retardation, microcephaly, hypertelorism, epicanthal folds, hyptonia, and a high-pitched monochromatic cry that is usually considered diagnostic for the syndrome. Recently, a correlation between clinical features and the extent of the chromosome 5 deletions has identified two regions of the short arm that appear to be critical for the abnormal development manifested in this syndrome.

  10. Conversation, speech acts, and memory.

    PubMed

    Holtgraves, Thomas

    2008-03-01

    Speakers frequently have specific intentions that they want others to recognize (Grice, 1957). These specific intentions can be viewed as speech acts (Searle, 1969), and I argue that they play a role in long-term memory for conversation utterances. Five experiments were conducted to examine this idea. Participants in all experiments read scenarios ending with either a target utterance that performed a specific speech act (brag, beg, etc.) or a carefully matched control. Participants were more likely to falsely recall and recognize speech act verbs after having read the speech act version than after having read the control version, and the speech act verbs served as better recall cues for the speech act utterances than for the controls. Experiment 5 documented individual differences in the encoding of speech act verbs. The results suggest that people recognize and retain the actions that people perform with their utterances and that this is one of the organizing principles of conversation memory.

    Résumé Objectif Selon des études précédentes, les dossiers de santé électroniques peuvent améliorer l’efficacité, la sécurité et la qualité de la prise en charge médicale. Cependant, les prestataires de soins restent réticents quant à son utilisation, ce qui limite son impact sur le système de santé. La présente étude avait pour objectif d’évaluer les perceptions des médecins face au dossier de santé du Québec. Méthodes À partir d’une revue de la littérature sur les facteurs influençant l’adoption des nouvelles technologies de l’information et des communications (NTIC) en général et de la cybersanté en particulier, nous avons élaboré un questionnaire semi-structuré. Au total, 12 médecins utilisateurs potentiels du dossier de santé du Québec (DSQ) ont complété et retourné le questionnaire. Par la suite, nous avons opéré une analyse thématique de contenu, suivie par une théorisation des concepts obtenus. Résultats L’intention d’adopter le DSQ est influencée positivement par l’utilité perçue, la facilité d’utilisation perçue, la démonstrabilité des résultats, la compatibilité du système avec la pratique et l’autoefficacité informatique perçue par les médecins. Inversement, la résistance au changement influence négativement l’adoption du DSQ par les médecins. Conclusion L’identification des déterminants de l’adoption du dossier de santé du Québec est cruciale pour les responsables du secteur de la santé au Québec. Il sera ainsi possible de saisir les attentes des utilisateurs potentiels et d’ajuster les stratégies d’implantation en vue de favoriser une meilleure intégration de cette technologie dans les pratiques médicales.

    2009-01-01

    The Federal Employees' Compensation Act (FECA) program provides wage loss compensation and payments for medical treatment to federal civilian employees. Administered by the Department of Labor (DOL), FECA covers over 2.7 million federal employees in more than 70 different agencies. FECA costs rose from $1.4 billion in 1990 to $2.6 in 2006, while the federal workforce remained essentially unchanged. While federal civilian employees represent only 2.1% of all workers eligible for workers' compensation benefits, federal programs account for 6% of the benefits paid. Disability benefits under FECA are far greater than those in the state workers' compensation programs. The benefit payments often exceed the former salary of the injured employee. The last congressional hearings on the FECA program were held over thirty years ago. It is unlikely that Congressional review will occur any time soon, as the entrenched bureaucracy that benefits from the FECA program defines and protects its future.

    Preliminary results are presented for three propagation measurement campaigns involving a mobile receiving laboratory and 20 GHz transmissions from the Advanced Communications Technology Satellite (ACTS). Four 1994 campaigns were executed during weekly periods in and around Austin, Texas in February and May, in Central Maryland during March, and in Fairbanks, Alaska and environs in June. Measurements tested the following effects at 20 GHz: (1) attenuation due to roadside trees with and without foliage, (2) multipath effects for scenarios in which line-of-sight paths were unshadowed, (3) fades due to terrain and roadside obstacles, (4) fades due to structures in urban environs, (5) single tree attenuation, and (6) effects of fading at low elevation angles (8 deg in Fairbanks, Alaska) and high elevation angles (55 deg in Austin, Texas). Results presented here cover sampled measurements in Austin, Texas for foliage and non-foliage cases and in Central Maryland for non-foliage runs.

    A high-current, fast-acting switch is designed for utilization as a crowbar switch in a high-current circuit such as used to generate the magnetic confinement field of a plasma-confining and heat device, e.g., Pyrotron. The device particularly comprises a cylindrical housing containing two stationary, cylindrical contacts between which a movable contact is bridged to close the switch. The movable contact is actuated by a differential-pressure, airdriven piston assembly also within the housing. To absorb the acceleration (and the shock imparted to the device by the rapidly driven, movable contact), an adjustable air buffer assembly is provided, integrally connected to the movable contact and piston assembly. Various safety locks and circuit-synchronizing means are also provided to permit proper cooperation of the invention and the high-current circuit in which it is installed. (AEC)

    Les traumatismes graves du rein de grade III, IV et V selon la classification de l'Amercan Society for Surgery For Trauma (ASST) sont plus rares et se retrouvent dans 5% des cas en moyenne. Leur prise en charge est souvent délicate, nécessitant alors des centres expérimentés dotés de moyen adéquats d'imagerie (scanner spiralé). Cependant, durant ces dernières années, la prise en charge de ces traumatismes a évolué vers une attitude de moins en moins chirurgicale grâce à l’évolution des techniques de la radiologie interventionnelle, de l'endourologie et des moyens de surveillance aux urgences et de réanimation. L'objectif de cette étude est d’évaluer notre expérience dans la prise en charge des traumatismes rénaux de haut grade. Notre étude rétrospective porte sur 25 cas de traumatismes grave du rein de grade III, IV et V selon la classification de l'ASST, colligés entre Janvier 2002 et Juin 2009 au service d'urologie du centre Hospitalier Universitaire Mohammed VI, Université Cadi Ayyad de Marrakech, Maroc. Nous avons étudié les données épidémiologiques, les signes cliniques et biologiques à l'admission (état de choc hémorragique, taux d'hémoglobine), les données radiologiques (échographie et scanner), les lésions associées, la prise en charge thérapeutique et les complications. L’âge moyen de nos patients était de 24,9 ans 15 et 58 ans, avec une prédominance masculine (sex-ratio = 7, 3). Le rein droit était intéressé dans 15 cas (60%). Le traumatisme rénal était fermé dans 15 cas, et ouvert par arme blanche dans 10 cas. Huit patients se sont présentés en état de choc hémorragique (32%). Une anémie inférieur à 10g /100ml a été observée dans 10 cas (40%). L'uroscanner fait systématiquement à l'admission a retrouvé un grade III (10 cas), grade IV (13 cas) et grade V (2 cas).

    2001-12-01

    Ce travail est une étude du champ magnétique duns l'environnement circumstellaire des étoiles jeunes. Il a pour origine la certitude qu'avait l'auteur qu'il se devait d'être possible de détecter la présence d'un champ magnétique, et de possiblement le caractériser, par le biais d'observations de profils spectraux d'espèces moléculaires ioniques. Il en découle donc qu'un des buts principaux était de prouver que cela est effectivement possible. La thèse comporte alors des éléments théoriques et expérimentaux qui sont à la fois complémentaires et intimement liés. L'aspect théorique est basé sur l'interaction mutuelle que des particules neutres et chargées peuvent avoir l'une sur l'autre daps un plasma faiblement ionisé comme ceux existants daps les nuages moléculaires sites de formation stellaire. Il appert que la présence d'un champ magnétique a un effet direct sur le comportement des ions (via la force de Lorentz) et indirect sur les molécules neutres (via les nombreuses collisions entre les deux types de particules). Une telle interaction est, comme il est maintenant bien connu, présente dans les premières étapes de la formation dune étoile. Il s'agit bien sûr de la diffusion ambipolaire. Nous montrerons qu'il existe cependant un autre type de diffusion, jusqu'ici inconnue, qui se manifeste plus tard au tours de l'évolution des nuages moléculaires. Celle-ci peut avoir un effet dramatique sur l'apparence des profils spectraux (de rotation moléculaire) des espèces ioniques lorsque comparés à ceux qu'exhibent des espèces neutres coexistantes. Mais pour ce faire, il doit y avoir existence de mouvements organisés (des flots ou jets) de matière ou encore la présence de turbulence dans les régions considérées. Une distribution de vélocité du type maxwellienne ne révèlera pas la présence du champ magnétique. Les observations, qui ont pour but de confirmer la théorie, se situent dans le domaine des longueurs d

  19. Imagerie par modulation acoustique de conductivite electrique destinee au diagnostic du cancer du sein

    NASA Astrophysics Data System (ADS)

    Gendron, Mathieu

    This thesis describes a new medical imaging technique for determining the electrical conductivity distribution of tissues in a body region with a resolution comparable to that of current ultrasound techniques. The new technique, henceforth referred to as "Acousto-Electric Conductivity Modulation" (AECM) imaging, is based on the interaction of a sound wave with an electrical field. In its simplest form, four electrodes located near the region to be imaged apply a low-amplitude electrical current and measure the potential difference arising from current flow in the tissues. A focused ultrasound transducer directs a pressure wave to a voxel of the region of interest, modifying its conductivity distribution and, as a result, the amplitude of the potential measured by the electrodes. An image of the conductivity distribution can thus be constructed point-by-point by moving the electrodes and transducer to scan the object. In this context, the acoustic wave acts as the localization agent while the electrical potential provides a measure of the local conductivity change that occurs in the voxel. The first model presented in the thesis is based on the use of bipolar acoustic waves for excitation. This waveform is generally used with narrow band transducers. Acoustic waves generated by an ultrasound transducer driven with a burst of sine waves consists of alternating compression and rarefaction phases which tend to cancel each other in terms of the conductivity changes they produce. However when the thickness of the target object is small compared to the wavelength of the acoustic wave, this cancelling effect will not occur and the AECM signals will have sufficiently high amplitude to achieve image reconstruction using successive transducer positions to scan the region of interest. By extracting from the spectra of the AECM signals the amplitude of the peak at the excitation frequency, a map of the acousto-electric sensitivity of the system can be obtained. This map is then

    Le cancer du sein est le plus fréquent chez la femme et figure parmi les principales causes de mortalité liées au cancer. La curabilité de ce type tumoral est en augmentation, grâce aux programmes de dépistage et aux progrès thérapeutiques, qui ont certes augmenté la survie des patients. Mais des défis restent à relever en rapport avec l’instabilité phénotypique des cellules cancéreuses. L’objectif de ce travail est d’étudier le profil phénotypique du cancer du sein chez les patients pris en charge au Centre Mohammed VI pour le traitement des Cancers, durant les années 2013-2014. Il s’agit d’une étude transversale sur deux années, incluant les cas du cancer du sein pris en charge au Centre. Le recueil des données était fait à partir des dossiers des patients et analysés par le logiciel Epi Info. 1277 patients ont été pris en charge au sein de notre centre. 99,5% des cas de sexe féminin, l’âge moyen était 50,20 ± 11,34 ans. Le type histologique le plus fréquent était le carcinome canalaire infiltrant (80,7% des cas). Le stade diagnostic était précoce (56,9%). Le phénotype moléculaire le plus fréquent était le luminal A (41,4% des cas). Le luminal B, le HER2 et les triples négatifs étaient dans respectivement 10,4%, 6,3%, 11,2% des cas. L’étude du phénotype tumoral des patients atteints du cancer du sein permet l’orientation du clinicien dans le choix du traitement, et des décideurs dans la planification de programmes de lutte contre cette pathologie.

    Introduction Plusieurs facteurs font obstacles au don de sang dans les pays en développement. La présente étude avait pour objectifs d'analyser les connaissances, attitudes et pratiques de la population de Kisangani relatives au don de sang et d'identifier les obstacles au don de sang afin de guider la planification des activités de promotion du don de sang. Méthodes L’ enquête a été réalisée du 4 février au 27 août 2008 sur un échantillon de 1067 sujets par entretien. Résultats Sur 1067 sujets interviewés, 1002 (93.9%) sujets ont accepté de répondre. La plupart de nos enquêtés (81.5%, n=1002) avait connaissance de la pratique du don bénévole de sang à Kisangani. Quoique la majorité des sujets approuvent la pratique du don de sang, 57.9% (n=416) parmi eux n'ont jamais fait un don de sang. La raison principale avancé par ceux qui n'ont jamais fait un don de sang était qu'ils n'avaient pas été sollicités tandis que 35% (n=144), quoique sollicités, avaient refusés de faire un don de sang pour diverses raisons. Conclusion Cette enquête met en lumière le fait qu'il y a maintenant dans la population de Kisangani une attitude favorable au don de sang. Mais plusieurs obstacles empêchent encore le passage à l'acte. Des activités de promotion qui s'appuient sur la communication interpersonnelle devraient être mises sur pieds afin de passer des messages personnalisés aux donneurs potentiels de sang.

    I am honoured to present the 2016 British Journal of Sociology Annual Lecture at the London School of Economics. My lecture is based on ideas derived from my new book, The Scholar Denied: W.E.B. Du Bois and the Birth of Modern Sociology. In this essay I make three arguments. First, W.E.B. Du Bois and his Atlanta School of Sociology pioneered scientific sociology in the United States. Second, Du Bois pioneered a public sociology that creatively combined sociology and activism. Finally, Du Bois pioneered a politically engaged social science relevant for contemporary political struggles including the contemporary Black Lives Matter movement.

    This report is concerned with agents that act to gain information. In previous work, we developed agent models combining qualitative modeling with real-time control. That work, however, focused primarily on actions that affect physical states of the environment. The current study extends that work by explicitly considering problems of active information-gathering and by exploring specialized aspects of information-gathering in computational perception, learning, and language. In our theoretical investigations, we analyzed agents into their perceptual and action components and identified these with elements of a state-machine model of control. The mathematical properties of each was developed in isolation and interactions were then studied. We considered the complexity dimension and the uncertainty dimension and related these to intelligent-agent design issues. We also explored active information gathering in visual processing. Working within the active vision paradigm, we developed a concept of 'minimal meaningful measurements' suitable for demand-driven vision. We then developed and tested an architecture for ongoing recognition and interpretation of visual information. In the area of information gathering through learning, we explored techniques for coping with combinatorial complexity. We also explored information gathering through explicit linguistic action by considering the nature of conversational rules, coordination, and situated communication behavior.

    A double acting bit holder that permits bits held in it to be resharpened during cutting action to increase energy efficiency by reducing the amount of small chips produced. The holder consist of: a stationary base portion capable of being fixed to a cutter head of an excavation machine and having an integral extension therefrom with a bore hole therethrough to accommodate a pin shaft; a movable portion coextensive with the base having a pin shaft integrally extending therefrom that is insertable in the bore hole of the base member to permit the moveable portion to rotate about the axis of the pin shaft; a recess in the movable portion of the holder to accommodate a shank of a bit; and a biased spring disposed in adjoining openings in the base and moveable portions of the holder to permit the moveable portion to pivot around the pin shaft during cutting action of a bit fixed in a turret to allow front, mid and back positions of the bit during cutting to lessen creation of small chip amounts and resharpen the bit during excavation use.

  5. Fast-Acting Valve

    2003-01-01

    A fast-acting valve includes an annular valve seat that defines an annular valve orifice between the edges of the annular valve seat, an annular valve plug sized to cover the valve orifice when the valve is closed, and a valve-plug holder for moving the annular valve plug on and off the annular valve seat. The use of an annular orifice reduces the characteristic distance between the edges of the valve seat. Rather than this distance being equal to the diameter of the orifice, as it is for a conventional circular orifice, the characteristic distance equals the distance between the inner and outer radii (for a circular annulus). The reduced characteristic distance greatly reduces the gap required between the annular valve plug and the annular valve seat for the valve to be fully open, thereby greatly reducing the required stroke and corresponding speed and acceleration of the annular valve plug. The use of a valve-plug holder that is under independent control to move the annular valve plug between its open and closed positions is important for achieving controllable fast operation of the valve.

  6. Long-acting progestogens.

    Affandi, Biran

    2002-04-01

    Steroids can be administered in at least five different ways: injectables; hormone-releasing intra-uterine devices (IUDs); implants; vaginal rings; and pills. Progestogens which are synthetic steroids, are used as the main bioactive substances. Different progestogens are effective for different periods of time. Progestins in daily oral pills are effective for 24 hours. The effectiveness of a progestogen can be prolonged by incorporating it in a sustained-release system that gradually releases the hormone; therefore they can be effective up to 5 years or more. Two progestogen-only injectables are widely available in the family planning programmes, (DMPA and NET-EN) and two combined injectables, Cyclofem (DMPA + EC), and Mesigyna (NET-EN + EV). The ring is placed by the woman in her vagina, where it gradually releases hormone. Implantable contraceptives are placed just under the skin on the inside of the woman's arm. Implant capsules release the progestogen at a slow, steady rate. There are three implantables available in the market: Implanon; Norplant; and Jadelle. They are effective for 1-5 years, but then must be replaced. Natural and synthetic progestogens were first added to IUDs in the early 1970s. The main problem of long-acting progestogens is the disruption of the menstrual cycle.

  7. The act of interpretation.

    D'Abreu, Aloysio Augusto

    2006-08-01

    The author understands the interpreting act as an attempt to perceive what happens in the transference/countertransference field and not just what happens in the patient's mind. Interpretation transcends mere intellectual communication. It is also an experience in which analysts' emotions work as an important instrument in understanding their patients. Interpretation is seen to possess manifest as well as latent content; the latter would contain the analysts' feelings, emotions and personality. The unconscious content of an interpretation does not inconvenience or preclude the development of the analytic process, but, on the contrary, it allows new associative material to emerge, and it transforms the analytic session into a human relationship. Analysts' awareness of this content derived from patients' apperceptions is a significant instrument for understanding what is happening in the analytic relationship, and what transpires in these sessions provides fundamental elements for analysts' self-analysis. Some clinical examples demonstrate these occurrences in analytic sessions, and how they can be apprehended and used for a better understanding of the patient. The author also mentions the occurrence of difficulties during the analytic process. These difficulties are often the result of lapses in an analyst's perception related to unconscious elements of the relationship.

    In the present study, we investigated berberine‑induced apoptosis and the signaling pathways underlying its activity in FaDu head and neck squamous cell carcinoma cells. Berberine did not affect the viability of primary human normal oral keratinocytes. In contrast, the cytotoxicity of berberine was significantly increased in FaDu cells stimulated with berberine for 24 h. Furthermore, berberine increased nuclear condensation and apoptosis rates in FaDu cells than those in untreated control cells. Berberine also induced the upregulation of apoptotic ligands, such as FasL and TNF-related apoptosis-inducing ligand, and triggered the activation of caspase-8, -7 and -3, and poly(ADP ribose) polymerase, characteristic of death receptor-dependent extrinsic apoptosis. Moreover, berberine activated the mitochondria‑dependent apoptotic signaling pathway by upregulating pro-apoptotic factors, such as Bax, Bad, Apaf-1, and the active form of caspase-9, and downregulating anti-apoptotic factors, such as Bcl-2 and Bcl-xL. In addition, berberine increased the expression of the tumor suppressor p53 in FaDu cells. The pan-caspase inhibitor Z-VAD-fmk suppressed the activation of caspase-3 and prevented cytotoxicity in FaDu cells treated with berberine. Interestingly, berberine suppressed cell migration through downregulation of vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2, and MMP-9. Moreover, the phosphorylation of extracellular signal-regulated kinase (ERK1/2) and p38, components of the mitogen-activated protein kinase pathway that are associated with the expression of MMP and VEGF, was suppressed in FaDu cells treated with berberine for 24 h. Therefore, these data suggested that berberine exerted anticancer effects in FaDu cells through induction of apoptosis and suppression of migration. Berberine may have potential applications as a chemotherapeutic agent for the management of head and neck squamous carcinoma.

  9. Resistivity tomography of Pointe du Hoc cliffs for stability assessment

    Pointe du Hoc WWII battlefield overlooking the English Channel in western Normandy, France, is an important cultural resource, being an integral component of the June 6 1944 D-Day invasion. Two major buildings, the forward observation post (OP) and Col. Rudder's command post (RCP), are now perched perilously close to the cliff's edge owing to six decades of cliff retreat. Geophysical surveys were carried out in March 2008 to investigate the risk of cliff failure and to inform possible geotechnical remediation strategies with a final goal toward re-opening the observation post that is now closed to visitors. The geophysical surveying is accomplished by high-resolution resistivity tomography, conducted in extreme topography and in the midst of dense cultural clutter. The results of the OP tomography indicate that the highest mass movement hazard is associated with the marine caverns at the base of the cliff at the point of strongest wave attack. These caverns occupy the future site of a sea arch which will threaten the OP building. There is a high probability of a soil wedge failure on the east facing cliff edge close to the OP building. Such a failure could damage or destroy the building. The possibility of a sudden catastrophic failure along any one of these fractures cannot be ruled out. The greatest risk at the RCP site, which is under less immediate threat, is associated with soil wedge failures at the top of the cliffs.

  10. Obstacles to communication in children with cri du chat syndrome.

    Cri du chat syndrome (CCS) is a genetic disorder resulting from the deletion of the short arm of chromosome 5. Perhaps the most distinctive characteristic of this syndrome is the congenital high-pitched cry, which frequently brings these patients to the attention of an otolaryngologist. Speech and language development in children with CCS is notable for a reduced receptive vocabulary and a profound deficit in expressive language. Currently, no clear guidelines have been established for the treatment of the speech and language difficulties exhibited by these patients. In this article, we present a case report and discuss the current literature regarding the challenges to effective communication in CCS. Case report. We present a 7-year-old girl with CCS who sought help to improve her ability to communicate. The patient presented with a persistent high-pitched voice unchanged since birth and a breathy dysphonia. Findings on examination were significant for an abnormally oriented larynx with atrophic vocal folds. She continues to undertake intensive speech therapy to assist in her language development. CCS is a genetic disorder that universally results in profound deficits in expressive speech. Although patients with CCS commonly present with a high-pitched voice and marked laryngeal abnormalities, they are unlikely to benefit from surgical intervention. Speech and language therapy, including augmentative communication devices, may enhance effective communication and improve the quality of life of these patients.

    There are few data on the educational needs of children with cri-du-chat syndrome: a neurodevelopmental disorder that affects learning and development. We therefore designed an Internet survey to identify parents' educational priorities in relation to children's level of need/ability. The survey listed 54 skills/behaviors (e.g., toileting, expresses wants and needs, and tantrums) representing 10 adaptive behavior domains (e.g., self-care, communication, and problem behavior). Parents rated their child's current level of ability/performance with respect to each skill/behavior and indicated the extent to which training/treatment was a priority. Fifty-four surveys were completed during the 3-month data collection period. Parents identified nine high priority skills/behaviors. Results supported the view that parent priorities are often based on the child's deficits and emergent skills, rather than on child strengths. Implications for educational practice include the need for competence to develop high priority skills/behaviors and the value of assessing children's deficits and emergent skills to inform the content of individualized education plans.

    It has been well established that the 5p deletion causes Cri du chat syndrome, typically characterized by a cat‑like cry, and that duplication of 18q causes Edwards syndrome; the two are rare genetic abnormalities that separately lead to physical and mental impairments. However, the severity of the clinicopathological characteristics that arise when these two aberrations occur in one patient is unknown. Here, the first case in our knowledge of a single patient (a two‑year‑old female) with 5p partial monosomy and 18q partial trisomy is described. In the present study, chromosome microarray analysis was performed, which identified the imbalance of chromosomes 5 and 18 in the patient. The chromosome aberrations were further confirmed by fluorescence in situ hybridization. By comparing the phenotypes of combined case with those of the individual syndromes, severe clinical phenotypes of the 5p (5p15.33‑p13.3) deletion were confirmed, however, the net effect of the duplication of 18q22.3‑q23 was not determined, as this duplication only appeared to have a weak effect on the patient's phenotypes. The correlation between these chromosomal aberrations and their clinical features has implications for the identification of critical regions of 5p and 18q, particularly for the functional mapping of chromosome 18.

    la mise au point d'un modèle de simulation de la dernière passe du laminage à chaud du cuivre ne présente à priori pas de problème du point de vue numérique pour un code d'éléments finis non linéaire. La collecte d'informations précises tant sur le procédé industriel que sur le comportement du matériau est par contre une opération non triviale. Cet article présente les diverses méthodes expérimentales mises en œuvre pour caractériser le matériau : essais de compression à chaud, mesures d'analyse thermique différentielle, essais de dilatométrie et de diffusivité. Les méthodes permettant d'identifier les paramètres de la loi élasto-visco-plastique de type Norton-Hoff à partir des essais sont présentées et une analyse bibliographique investigue le problème de la détermination du module de Young à haute température.

  14. [Euthanasia and medical act].

    PubMed

    2011-05-01

    Right to life -as the prohibition of intentionally and arbitrarily taking life, even with authorization of the concerned one- is an internationally recognized right. In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.

    To present Cirque du Soleil's social circus program, Cirque du Monde, to explore its potential as a primary health care tool for family physicians. A review of the literature in PubMed, the Cochrane Library, PsycINFO, LaPresse, Eureka, Google Scholar, and Érudit using the key words circus, social circus, Cirque du Monde, and Cirque du Soleil; a Montreal-based initiative, Espace Transition, modeled on Cirque du Monde; and personal communication with Cirque du Soleil's Social Circus Training Advisor. The first 50 articles or websites identified for each key word in each of the databases were examined on the basis of their titles and abstracts in the case of articles, and on the basis of their titles and page content in the case of websites. Articles and websites that explored an aspect of social circuses or that described an intervention that involved circuses were then retained for analysis. Because all literature on social circuses was searched, no criterion for year of publication was used. No articles on the social circus as a health intervention were found. One study on the use of the circus as an intervention in schools was identified. It demonstrated an increase in self-esteem in the children who took part. One study on the use of the circus in a First Nations community was found; it contained nonspecific, qualitative findings. The other articles identified were merely descriptions of social circuses. One website was identified on the use of the social circus to help youth who had been treated in a hospital setting for major psychiatric disorders to re-enter the community. The team in the pediatric psychiatry department at Centre Hospitalier Universitaire Sainte-Justine, the children's hospital in Montreal, Que, was contacted; they were leading this project, called Espace Transition. The unpublished preliminary findings of its pilot project demonstrate substantial improvements in overall patient functioning. According to Cirque du Soleil, there are several

    Le georadar (Ground Penetrating Radar (GPR)) constitue une technique de controle non destructif (CND) interessante pour la mesure des epaisseurs des dalles de beton et la caracterisation des fractures, en raison de ses caracteristiques de resolution et de profondeur de penetration. Les equipements georadar sont de plus en plus faciles a utiliser et les logiciels d'interpretation sont en train de devenir plus aisement accessibles. Cependant, il est ressorti dans plusieurs conferences et ateliers sur l'application du georadar en genie civil qu'il fallait poursuivre les recherches, en particulier sur la modelisation et les techniques de mesure des proprietes electriques du beton. En obtenant de meilleures informations sur les proprietes electriques du beton aux frequences du georadar, l'instrumentation et les techniques d'interpretation pourraient etre perfectionnees plus efficacement. Le modele de Jonscher est un modele qui a montre son efficacite dans le domaine geophysique. Pour la premiere fois, son utilisation dans le domaine genie civil est presentee. Dans un premier temps, nous avons valide l'application du modele de Jonscher pour la caracterisation de la permittivite dielectrique du beton. Les resultats ont montre clairement que ce modele est capable de reproduire fidelement la variation de la permittivite de differents types de beton sur la bande de frequence georadar (100 MHz-2 GHz). Dans un deuxieme temps, nous avons montre l'interet du modele de Jonscher en le comparant a d'autres modeles (Debye et Debye-etendu) deja utilises dans le domaine genie civil. Nous avons montre aussi comment le modele de Jonscher peut presenter une aide a la prediction de l'efficacite de blindage et a l'interpretation des ondes de la technique GPR. Il a ete determine que le modele de Jonscher permet de donner une bonne presentation de la variation de la permittivite du beton dans la gamme de frequence georadar consideree. De plus, cette modelisation est valable pour differents

Ils permettent d'ameliorer la resistance a l'usure et a la fatigue en durcissant les zones critiques superficielles par des apports thermiques courts et localises. Parmi les procedes qui se distinguent par leur capacite en terme de puissance surfacique, le traitement thermique de surface au laser offre des cycles thermiques rapides, localises et precis tout en limitant les risques de deformations indesirables. Les proprietes mecaniques de la zone durcie obtenue par ce procede dependent des proprietes physicochimiques du materiau a traiter et de plusieurs parametres du procede. Pour etre en mesure d'exploiter adequatement les ressources qu'offre ce procede, il est necessaire de developper des strategies permettant de controler et regler les parametres de maniere a produire avec precision les caracteristiques desirees pour la surface durcie sans recourir au classique long et couteux processus essai-erreur. L'objectif du projet consiste donc a developper des modeles pour predire le profil de durete dans le cas de traitement thermique de pieces en acier AISI 4340. Pour comprendre le comportement du procede et evaluer les effets des differents parametres sur la qualite du traitement, une etude de sensibilite a ete menee en se basant sur une planification experimentale structuree combinee a des techniques d'analyse statistiques eprouvees. Les resultats de cette etude ont permis l'identification des variables les plus pertinentes a exploiter pour la modelisation. Suite a cette analyse et dans le but d'elaborer un premier modele, deux techniques de modelisation ont ete considerees, soient la regression multiple et les reseaux de neurones. Les deux techniques ont conduit a des modeles de qualite acceptable avec une precision d'environ 90%. Pour ameliorer les performances des modeles a base de reseaux de neurones, deux

    Le syndrome du QT long congénital est une maladie rythmique liée à une mutation génétique et caractérisée par un espace QT allongé sur l’électrocardiogramme, des arythmies malignes type torsade de pointe et fibrillation ventriculaire entraînant une mort subite. Les gènes impliqués dans ces mutations codent pour des sous unités des canaux ioniques responsables de l'activité électrique cardiaque. Le diagnostic est basé sur l’électrocardiogramme, une enquête familiale et l’étude génétique. Le traitement repose sur les bêtabloquants, la sympathectomie et le stimulateur cardiaque. Nous rapportons le cas d'un nourrisson de 2 ans retrouvé en état de mort apparente. Nous discutons de sa prise en charge initiale, de l'enquête familiale et de son suivi ultérieur. PMID:25667708

  13. The interaction between wheat germ agglutinin and other plant lectins with prostate cancer cells Du-145.

    PubMed

    Gabor, F; Klausegger, U; Wirth, M

    2001-06-19

    The bioadhesive properties of fluorescein-labeled plant lectins with different carbohydrate specificities were investigated by flow cytometry at 4 and 37 degrees C using Du-145 prostate cancer cells. At both temperatures the lectin association rate increased following the order: Dolichos biflorus agglutinin (DBA)Du-145 cells. Both, the BSA-binding capacity of the cells referring to nonspecific binding and inhibition studies using the complementary carbohydrate, assured specificity of the lectin-cell interactions except for DBA. The WGA-association rate of Du-145 cells was dependent on temperature indicative for cellular uptake of membrane-bound WGA. Intracellular enrichment of WGA was confirmed by confocal microscopy. As resulted from experiments in presence of ouabain active transport mechanisms were involved in cellular uptake of WGA. Equilibration of the intracellular pH with monensin pointed to accumulation of intracellular located WGA within acidic compartments of Du-145 cells such as the lysosomes or the trans-Golgi complex. Consequently the interaction of WGA with Du-145 cells at 37 degrees C is a one way process due to immediate active transport of membrane-bound lectin into acidic compartments of prostate cancer cells.

    The effect of telmisartan on prostate cancer DU145 cell survival and the underlying mechanism of apoptosis involving peroxisome proliferator-activated receptor (PPAR) pathway were investigated. Cultured DU145 cells were treated pharmacologically with telmisartan and GSK0660 (a PPAR-delta antagonist); or by RNA interference with siRNA of PPAR-delta. The treatment effects on cell survival were evaluated with cell viability assay, life and dead cell staining and flow cytometry. Western blot analysis for PPAR-delta protein expression was also performed. The results showed that telmisartan (0-80 µm) dose-dependently reduced DU145 cell survival. Flow cytometry demonstrated cancer cell cycle arrest with increase of sub-G1 phase. GSK0660 partially but significantly restored the telmisartan-treated cell viability. Similarly, siRNA of PPAR-delta significantly reversed the telmisartan-induced apoptosis. Western blot showed that telmisartan significantly increased DU145 cell PPAR-delta protein expression. Co-incubation with siRNA of PPAR-delta inhibited the telmisartan effect of PPAR-delta up-regulation. In conclusion, telmisartan induces prostate cancer DU145 cells apoptosis through the up-regulation of PPAR-delta protein expression. Pharmacological inhibition or genetic silencing of PPAR-delta activity can both reverse the telmisartan-induced apoptotic effect. Thus the PPAR-delta pathway might be a potential target for the treatment of prostate cancer. Copyright © 2016 Elsevier B.V. All rights reserved.

    Huang-Lian-Jie-Du-Tang (HLJDT) is a classic TCM formula to clear “heat” and “poison” that exhibits antirheumatic activity. Here we investigated the therapeutic mechanisms of HLJDT at protein network level using bioinformatics approach. It was found that HLJDT shares 5 target proteins with 3 types of anti-RA drugs, and several pathways in immune system and bone formation are significantly regulated by HLJDT's components, suggesting the therapeutic effect of HLJDT on RA. By defining an antirheumatic effect score to quantitatively measure the therapeutic effect, we found that the score of each HLJDT's component is very low, while the whole HLJDT achieves a much higher effect score, suggesting a synergistic effect of HLJDT achieved by its multiple components acting on multiple targets. At last, topological analysis on the RA-associated PPI network was conducted to illustrate key roles of HLJDT's target proteins on this network. Integrating our findings with TCM theory suggests that HLJDT targets on hub nodes and main pathway in the Hot ZENG network, and thus it could be applied as adjuvant treatment for Hot-ZENG-related RA. This study may facilitate our understanding of antirheumatic effect of HLJDT and it may suggest new approach for the study of TCM pharmacology. PMID:24348693

  16. Acting to let someone die.

    McGee, Andrew

    2015-02-01

    This paper examines the recent prominent view in medical ethics that withdrawing life-sustaining treatment (LST) is an act of killing. I trace this view to the rejection of the traditional claim that withdrawing LST is an omission rather than an act. Although that traditional claim is not as problematic as this recent prominent view suggests, my main claim is that even if we accepted that withdrawing LST should be classified as an act rather than as an omission, it could still be classified as letting die rather than killing. Even though omissions are contrasted with acts, letting die need not be, for one can let die by means of acts. The remainder of the paper is devoted to establishing this claim and addresses certain objections to it. © 2013 John Wiley & Sons Ltd.

De 2002 à 2010, 625 patientes étaient prises en charge pour cancer du sein au service de Gynécologie-Obstétrique «C» du centre hospitalier universitaire de Casablanca. 22 cas de cancer bilatéral synchrone étaient diagnostiqués. Nos résultats sont comparés avec ceux de la littérature. La fréquence de la bilatéralité du cancer du sein synchrone était de 3,52% (22/625). L'intervalle de temps moyen entre les deux cancers est de 4 mois (0 à 6 mois). Les patientes âgées de moins de 40 ans lors du premier cancer avaient six fois plus de risque de développer un cancer au niveau du sein controlatéral que les femmes âgées de plus de 40 ans. Les patientes atteintes d'une tumeur T3 ou T4 avaient un risque neuf fois plus élevé que les autres. 90,9% (2/22) des cas des premiers cancers sont des adénocarcinomes infiltrants. Les types histologiques du premier et du douzième cancer étaient identiques dans 86,4% (19/22) des cas. Quant au pronostic, il dépend à la fois du stade du premier et du deuxième cancer et le traitement de ce dernier doit obéir aux mêmes règles du traitement du premier cancer. L'incidence du cancer bilatéral synchrone du sein est de 3,52% dans notre série. Le cancer du sein unilatéral constitue un facteur de risque de développement d'un cancer du sein controlatéral. Une surveillance à vie est nécessaire au cours d'un cancer du sein pour détecter un cancer controlatéral. PMID:26090066

  18. La genèse du concept de champ quantique

    NASA Astrophysics Data System (ADS)

    Darrigol, O.

    This is a historical study of the roots of a concept which has proved to be essential in modern particle physics : the concept of quantum field. The first steps were accomplished by two young theoreticians : Pascual Jordan quantized the free electromagnetic field in 1925 by means of the formal rules of the just discovered matrix mechanics, and Paul Dirac quantized the whole system charges + field in 1927. Using Dirac's equation for electrons (1928) and Jordan's idea of quantized matter waves (second quantization), Werner Heisenberg and Wolfgang Pauli provided in 1929-1930 an extension of Dirac's radiation theory and the proof of its relativistic invariance. Meanwhile Enrico Fermi discovered independently a more elegant and pedagogical formulation. To appreciate the degree of historical necessity of the quantization of fields, and the value of contemporaneous critics to this approach, it was necessary to investigate some of the history of the old radiation theory. We present the various arguments however provisional or naïve or wrong they could be in retrospect. So we hope to contribute to a more vivid picture of notions which, once deprived of their historical setting, might seem abstruse to the modern user. Nous présentons une étude historique des origines d'un concept devenu essentiel dans la physique moderne des particules : le concept de champ quantique. Deux jeunes théoriciens franchirent les premières étapes : Pascual Jordan quantifia le champ électromagnétique en 1925 grâce aux règles formelles de la mécanique des matrices naissante, et Paul Dirac quantifia le système complet charges + champ en 1927. Au moyen de l'équation de l'électron de Dirac (1928) et de l'idée de Jordan d'ondes de matière quantifiées (deuxième quantification), Werner Heisenberg et Wolfgang Pauli donnèrent en 1929-1930 une extension de la théorie du rayonnement de Dirac et la preuve de son invariance relativiste. Pendant ce temps Enrico Fermi découvrit ind

    measurements were then corrected to bring them in the same altimetry reference level as Topex/Poseidon, thereby producing time series of 17 years (1992-2009). Following this analysis, we proposed a waveform retracking algorithm that integrates the backscattering coefficient to the time scale of penetration of the radar pulse in a medium with a presence of vegetation. The idea here is to consider the heterogeneity of a medium such as the Delta, which can be covered with vegetation. For this, we introduce into the equation of the waveform, the backscattering coefficient estimated from the so called water cloud model, to create a new algorithm called retracking algorithm of water cloud. This algorithm was applied to the Envisat and OSTM/Jason-2 data. The results of the algorithm were validated with in situ measurements of the Direction Nationale de l'Hydraulique du Mali and also with measurements acquired during a campaign of data collection conducted between August and October 2009. The observed differences are generally small (<+/- 1 m). The retracking algorithm of water cloud was compared to other existing algorithms. It shows a strong correlation with Ice-1 (R 2 = 0,84). Finally, we analyzed the influence of precipitation on the variations of the altimetry-derived water levels. Three sources of precipitations from satellite measurements and reanalysis data were considered in three catchments (basin Fouta Djallon in upstream, Bani basin and the inner basin in Mali). The analysis reveals the importance of precipitations, particularly in the basin of Fouta Djallon. Approximately 70% of sites analyzed in the Delta show a relatively strong correlation (R2 > 0,40) with the cumulative precipitations in the basins considered.

    2012-12-01

    The Pic du Midi coronagraph (CLIMSO) is a group of four instruments in parallel, taking images of the whole solar photosphere and low corona. It provides series of 2048*2048 pixels images taken nominally at 1 minute time intervals, all year long, weather permitting. A team of ≃q 60 persons, by groups of 2 or 3 each week, operate the instruments. Their work is programmed in collaboration with Institut de Recherches en astrophysique et planétologie (IRAP) of Observatoire Midi Pyrénées (OMP), and with Programme National Soleil Terre (PNST). The four instruments of CLIMSO (L1, C1, L2 and C2) collect images of the Sun as following: 1) L1 : photosphere in H-α (656.28 nm) ; 2) L2 : photosphere in Ca-II (393.37 nm) ; 3) C1 : prominences in H-α ; 4) C2 : prominences in He-I (1083.0 nm). The data taken are stored in fits format images and mpeg films. They are available publicly on data bases such as BASS 2000 Meudon ({http://bass2000.obspm.fr/home.php?lang=en} and BASS2000 Tarbes ({http://bass2000.bagn.obs-mip.fr/base/sun/index.php}). Several solar studies are carried in relation with these data. In addition to the raw fits images, new images will soon be sent to the data bases: they will be calibrated in solar surface emittance, expressed in W/m^2/nm/steradian. Series of mpeg films for each day are presented in superposed color layers, so as to visualize the multispectral information better. New instrumental developments are planned for the next years and already financed. They will use spectropolarimetry to measure the magnetic field and radial velocities in the photosphere and corona. The data will cover the entire solar disc and have a sample rate of one map per minute.

    The aim of this study was to evaluate the impact of CSC on insensitivity to radiotherapy in HNSCC. A radioresistant cell line, FaDu-R, was established using fractionated ionizing radiation. Cells with high and low CD44/ALDH activity were isolated. FaDu-R cells demonstrated significantly increased cell viability after radiation exposure compared with parental cells. CD44(high)/ALDH(high) FaDu-R cells demonstrated significantly faster wound closure (p<0.05) and more efficient invasion (p<0.05) compared to the CD44(high)/ALDH(high) FaDu cells or the CD44(low)/ALDH(low) FaDu-R cells. There was a significant difference in tumor volume between the CD44(high)/ALDH(high) FaDu-R cells and the CD44(high)/ALDH(high) FaDu cells (p<0.05) as well as the CD44(low)/ALDH(low) FaDu-R cells (p<0.05). Cancer stem cells (CSC) were associated with invasion and tumorigenesis in a radioresistant head and neck squamous cell carcinoma (HNSCC) cell line. This concept might help to improve the understanding of these mechanisms and to develop drugs that can overcome radioresistance during radiotherapy. Copyright © 2017 Elsevier B.V.

    Depleted uranium (DU) weapons testing programmes have been conducted at two locations within the UK. An investigation was therefore carried out to assess the extent of any environmental contamination arising from these test programmes using both alpha spectrometry and mass spectrometry techniques. Uranium isotopic signatures indicative of DU contamination were observed in soil, plant and earthworm samples collected in the immediate vicinity of test firing points and targets, but contamination was found to be localised to these areas. This paper demonstrates the superiority of the (235)U : (238)U ratio over the (234)U : (238)U ratio for identifying and quantifying DU contamination in environmental samples, and also describes the respective circumstances under which alpha spectrometry or mass spectrometry may be the more appropriate analytical tool.

    Biochemical characterizations of food allergens are required for understanding the allergenicity of food allergens. Such studies require a relatively large amount of highly purified allergens. The level of Pru du 4 in almond is low, and its expression in a soluble form in Escherichia coli required an expression tag. An MBP tag was used to enhance its expression and solubility. Sumo was used for the first time as a peptidase recognition site. The expression tag was removed with a sumo protease, and the resulting wild-type Pru du 4 was purified chromatographically. The stability of the allergen was investigated with chemical denaturation. The Gibbs free energy of Pru du 4 folding-unfolding transition was determined to be 5.4 ± 0.7 kcal/mol.

    The purification, identification, crystallization and preliminary crystallographic studies of an allergy-related protein, Pru du amandin, from P. dulcis nuts are reported. Food allergies appear to be one of the foremost causes of hypersensitivity reactions. Nut allergies account for most food allergies and are often permanent. The 360 kDa hexameric protein Pru du amandin, a known allergen, was purified from almonds (Prunus dulcis) by ammonium sulfate fractionation and ion-exchange chromatography. The protein was identified by a BLAST homology search against the nonredundant sequence database. Pru du amandin belongs to the 11S legumin family of seed storage proteins characterized by the presence of a cupin motif. Crystals were obtained by the hanging-drop vapour-diffusion method. The crystals belong to space group P4{sub 1} (or P4{sub 3}), with unit-cell parameters a = b = 150.7, c = 164.9 Å.

  11. Generalized hydrology of prairie potholes on the Coteau du Missouri, North Dakota

    USGS Publications Warehouse

    Eisenlohr, William Stewart; Sloan, Charles E.

    1968-01-01

    This report presents all the information, obtained during the investigation, that lends itself to generalization. It describes conditions on that part of the Coteau du Missouri where there is little integration of drainage systems. The surface of the glacial drift in this region is dotted with shallow depressions known as prairie potholes that hold water for varying lengths of time. Precipitation directly on a pothole is the basic source of its water supply, but it is only about half the potential evaporation; therefore, potholes tend to go dry. Basin inflow from melting snow or rain occurs only when the soil is frozen or saturated, a condition so erratic in occurrence that seasonal or annual precipitation is of little value as an indication of basin inflow. Net seepage outflow occurs from potholes on the higher parts of the Coteau at very low rates, but it can amount to 20 to 30 percent of the total water loss from a pothole. Net seepage inflow occurs at the potholes on the lower parts of the Coteau. The phreatic surface (water table) tends to be a subdued image of the topography and is generally very near the land surface. The water surfaces of the potholes are part of the phreatic surface, and therefore they can be used to prepare a contour map of the phreatic surface; wells usually act as piezometers and thus are useless for such a purpose. Generally, potholes with water relatively low in dissolved solids have net seepage outflow, and those with water containing high concentration of dissolved solids have net seepage inflow. The direction of ground-water movement can therefore be inferred from the quality of water in potholes. The total salinity of water in a pothole is largely a function of the rate of ground-water flow and the relationship of seepage inflow to outflow. The species of emergent aquatic vegetation that grow in a pothole are directly related to the permanence and salinity of the water at the particular site of each species. The report contains a

  12. Applications of DuPont photopolymer Cromalin(R) for dry deposition of particles

    NASA Astrophysics Data System (ADS)

    Hurt, Michielle Helene

    2006-04-01

    A dry deposition method for patterning particles for specific applications of emissive display screens, photocatalysts and nanoparticles, using DuPont Tacky DotRTM photopolymer, was developed. This tacky photopolymer, CromalinRTM, may be adhered to various substrates and patterned through the polymerization of the adhesive when exposed to UV light. It was found that CromalinRTM is activated at a wavelength of 340--370 nm and has a patterning resolution as measured by the USAF 1951 resolution target to be ˜20 mum. Phosphor, alumina, titania, toner and various types of nanometer-sized materials, including carbon nanotubes, mesoporous silica nanoparticles, silver nanowires and magnetic magnetite nanoparticles were adhered to Positive CromalinRTM. These particles were shown to become adhered and embedded within the tacky photopolymer layer. Patterning of these nanomaterials was also found to be successful. Particle loading evaluations showed a monolayer of particles was adhered to the surface with an increase in deposit density and coverage when a layer of large diameter particles was followed by a layer of small diameter particles. A tape test showed the adhesion of particles to the surface is adequate (˜50 N) for the investigated applications and is dependent on particle shape. The decomposition properties of this adhesive material were evaluated to be suitable for emissive display screens and photocatalysis processes. The thermal degradation of the polymer in argon at 450°C was ˜83-86 wt.%. Adhesion increased with limited UV exposure and the solubility in water and acetone of Positive Cromalin RTM decreased. Multiple adhesion mechanisms may contribute to the adhesion of various particle shapes and materials to Positive CromalinRTM. The elastic behavior of CromalinRTM allows particles to become completely or partially embedded into the photopolymer layer. This intimate contact allows surface forces, such as van der Waals, to act at the interface of the polymer

    Introduction Les antivitamines K (AVK), traitement anticoagulant oral le plus largement prescrit, posent un réel problème de santé publique du fait de leur risque iatrogène. L'objectif de cette étude était de préciser le niveau de connaissance des patients sur la gestion de leur traitement par les AVK. Méthodes Il s'est agi d'une enquête transversale descriptive réalisée au CHU-Yalgado Ouédraogo, sur une période de 03 mois : du 1er mars au 31 mai 2012. Un questionnaire a été administré aux patients bénéficiant d'un traitement AVK depuis au moins un mois. Résultats Soixante-dix patients ont été inclus dans l'étude dont 30 hommes. L'âge moyen était de 49 ans ± 16 ans. Les cardiopathies et la maladie thromboembolique veineuse justifiant l'institution du traitement AVK étaient retrouvées respectivement dans 58,6% et 41,4% des cas. Le nom de l'AVK et la raison exacte du traitement étaient connus respectivement dans 91,4% et 67,1% des cas. Plus de la moitié des patients (68,6%) savaient que les AVK rendaient le sang plus fluide. Quarante-six patients (65,7%) citaient l'INR comme examen biologique de surveillance du traitement et seulement 28 patients (40%) connaissaient les valeurs cibles. La majorité des patients ne connaissait pas les risques encourus en cas de surdosage (72,8%) et de sous-dosage (71,4%). Une automédication par anti-inflammatoire non stéroïdien était signalée par 18 patients (25,7%). Les choux (74,3%) et la laitue (62,9%), aliments à consommer avec modération, étaient les plus cités. Conclusion Les connaissances des patients sur la gestion des AVK étaient fragmentaires et insuffisantes pour assurer la sécurité et l'efficacité du traitement. La création d'un programme d'éducation thérapeutique sur les AVK s'avère alors nécessaire. PMID:25870741

    Nous rapportons le cas d'une patiente de 7 ans qui a consulté pour une douleur abdominale aigue paroxystique siégeant au niveau de l'épigastre associée à des vomissements sans arrêt des matières et des gaz. L'examen clinique ainsi que le bilan biologique étaient sans particularité. L'échographie abdominale demandée en première intention a montré une masse du flanc et de la fosse iliaque droite échogène, homogène à contours réguliers sans signal vasculaire au Doppler associée à un signe du tourbillon des vaisseaux mésentériques. A la tomodensitométrie cette masse correspondait à une formation lipomateuse, bien limitée, exerçant un effet de masse sur le cœcum avec volvulus du mésentère au contact. La disposition des vaisseaux mésentériques à leur origine était normale. Le diagnostic de volvulus du mésentère sur lipome a été retenu. La prise en charge chirurgicale et l'analyse anatomopathologique de la pièce opératoire a confirmé le diagnostic. Nous allons à travers ce cas clinique revoir l'apport de l'échographie et du scanner dans le diagnostic de volvulus du mésentère. PMID:28250879

    L'objectif de ce travail est de présenté deux cas de carcinomes papillaire sur kystes du tractus thyréoglosse (KTT) et d'exposer notre attitude thérapeutique. Il s'agit de deux patientes, une âgée de 30 ans et l'autre de 45 ans, qui ont été opéré dans notre centre. Le diagnostic du carcinome papillaire sur KTT a été retenu après étude anatomopathologique du kyste après exérèse selon la technique de Sistrunk. Une thyroïdectomie totale suivie d'une irathérapie et d'une hormonothérapie freinatrice a été réalisé chez l'une des patientes, pour l'autre une thyroïdectomie totale associée à une hormonothérapie freinatrice a été préconisé. L'évolution été favorable après un recule de 4 ans pour la première patiente et de 2 ans pour la deuxième. La thyroïdectomie totale après exérèse complète du KTT est le traitement recommandé pour le carcinome papillaire sur KTT. Il a été démontré qu'un cancer latent de la thyroïde peut être développé même après des années après l'exérèse du KTT. Le traitement du carcinome papillaire sur KTT est bien codifié, permettant un excellent pronostic. PMID:26848352

  16. Long-term corrosion and leaching of depleted uranium (DU) in soil.

    2007-08-01

    Corrosion and leaching of depleted uranium (DU) was investigated for 3 years using six DU munitions (145-264 g DU) each buried in a column with a soil core of about 3.3 kg dry soil mass. The columns were installed in an air-conditioned laboratory. Each week they were irrigated and (238)U was determined in the effluents by inductively coupled plasma mass spectrometry. In addition, (235)U was measured occasionally to assure that the (238)U was predominantly from the DU munition. On average, 14.5 g corresponding to 7.9% of the initial DU mass was corroded after 3 years, indicating an increased corrosion as compared to the first year of observation. The leaching rates increased much stronger than the corrosion rates by factors of more than 100, resulting in a mean total amount of leached (238)U of 13 mg as compared to 0.03 mg after the first year. Uranium species identified in the seepage water by time-resolved laser-induced fluorescence spectroscopy were mainly hydroxo and carbonate compounds, while those in the corroded material were phosphate compounds. It is concluded that the dramatic increase of the leaching and its large temporal variability do not allow any extrapolation for the future. However, the high (238)U concentrations observed in the seepage water highlight the need for further investigations on the transport of (238)U through soil, in particular with regard to the potential future (238)U contamination of groundwater in areas affected by DU weapons.

    The OLYMPUS and ACTS satellites both provide opportunities for 10 to 30 GHz propagation measurements. The spacecraft are sufficiently alike that OLYMPUS can be used to test some prototype ACTS equipment and experiments. Data are particularly needed on short term signal behavior and in support of uplink power control and adaptive forward error correction (FEC) techniques. The Virginia Tech Satellite Communications Group has proposed a set of OLYMPUS experiments including attenuation and fade rate measurements, data communications, uplink power control, rain scatter interference, and small-scale site diversity operation. A digital signal processing receiver for the OLYMPUS and ACTS beacon signals is being developed.

Qualité des données D’abondantes recherches ont été publiées sur la fiabilité intra-évaluateur, inter-évaluateur et test-retest ainsi que sur la validité convergente, prédictive, du contenu et des groupes connus du test HINT, de même que sur la sensibilité, la spécificité et les valeurs prédictives négatives et positives des inquiétudes des parents, telles qu’évaluées par le test HINT. La plupart des données probantes sont de niveau II. Message principal Il est important de diagnostiquer les retards du développement moteur durant la première année de vie, car ils sont souvent le signe de retards du développement généralisés ou de déficiences précises, telles que la paralysie cérébrale. Les inquiétudes des parents quant au développement moteur de leur enfant sont une valeur prédictive robuste de diagnostics subséquents de retard du développement moteur. Conclusion Seul le dépistage précoce des retards du développement moteur, initialement par l’entremise d’outils de dépistage comme le test HINT, permet de recommander le patient à une intervention précoce qui profiterait tant à l’enfant qu’à sa famille.

    We analyze new multicolor light curves for four close late-type binaries: HS Aqr, EG Cep, VW LMi, and DU Boo, in order to determine the orbital and physical parameters of the systems and estimate the distances. The analysis is done using the modeling code of G. Djurasevic, and is based on up-to-date measurements of spectroscopic elements. All four systems have complex, asymmetric light curves that we model by including bright or dark spots on one or both components. Our findings indicate that HS Aqr and EG Cep are in semi-detached, while VW LMi and DU Boo are in overcontact configurations.

    Introduction Le cancer du sein représente un problème de santé publique au Maroc. L’objectif de ce travail était d’estimer le taux de survie au cancer du sein chez les patientes habitant la ville de Rabat. Méthodes Etude pronostique réalisée chez les patientes diagnostiquées pour cancer du sein de 2005 à 2008, habitant la ville de Rabat et enregistrées au registre des cancers de Rabat. La date d’inclusion dans l’étude correspondait à la date de confirmation histologique du cancer. L’estimation de la survie a été réalisée par la méthode de Kaplan Meier, et la comparaison entre les différentes classes d’une variable a été réalisée par le test de log rank. L’étude des facteurs associés à la survie a été effectuée par le modèle de Cox. Résultats Durant la période d’étude 628 cas de cancer du sein ont été collectés. Le pourcentage de décès était de 19,9%. La survie globale à un an était de 97,1%, elle était de 89,2% à 3 ans et de 80,6 % à 5 ans. En analyse multivariée la survie au cancer du sein était statistiquement moins bonne chez les patientes âgées de plus de 70 ans (p<0,001), ayantune grande taille de tumeur (p<0,001), un stade avancé d’adénopathies (p=0,007), présentant des métastases (p<0,001) et non traitées par hormonothérapie (p=0,002). Conclusion Une grande taille de la tumeur et la présence de métastases sont des facteurs de mauvais pronostic du cancer du sein d’où la nécessité de renforcer les programmes de dépistage.

  13. La nutrition du nourrisson né à terme et en santé

    PubMed Central

    1998-01-01

    La nutrition du nourrisson né à terme et en santé constitue le nouvel énoncé national sur la nutrition du nourrisson, de la naissance à l’âge de 24 mois. Il s’agit d’un projet conjoint de la Société canadienne de pédiatrie, des Diététistes du Canada et de Santé Canada. Cet ouvrage est une synthèse de la documentation scientifique actuelle en matière de nutrition du nourrisson ; il contient des principes et recommandations afin d’aider les professionnels de la santé à promouvoir la prestation des meilleurs soins alimentaires possibles pour les nourrissons du Canada, compte tenu de l’état actuel de la recherche. La collaboration entre les trois principaux organismes qui s’intéressent à cette question a permis d’uniformisé le message que les professionnels transmettront au public. Le document aborde quatre grands sujets relatifs à la première année d’existence : l’allaitement, les laits de remplacement, les autres liquides dans le régime du nourrisson et la transition aux aliments solides. On y examine ensuite la question de la sécurité dans l’alimentation, puis celle de la nutrition durant la deuxième année. La dernière section couvre les autres questions liées à la nutrition du nourrisson ; on y traite de sujets tels que les allergies alimentaires, les coliques, la constipation, les matières grasses dans le régime alimentaire, la carie dentaire, la gastroentérite, le diabète, l’anémie ferriprive et les régimes végétariens. Le document contient également un répertoire complet de plus de 200 citations. Le sommaire des principes et recommandations paraîtra dans les revues officielles de la Société canadienne de pédiatrie (Paediatrics and Child Health, 1998) et des Diététistes du Canada (Revue canadienne de pratique et de recherche en diététique, juin 1998). On peut télécharger le document intégral à partir des sites Web respectifs des trois organismes associés ; on peut aussi obtenir la

  14. Influence d'une substitution partielle du ciment par du laitier de hauts fourneaux sur la résistance des mortiers en milieu acide

    NASA Astrophysics Data System (ADS)

    Achoura, D.; Lanos, Ch.; Jauberthie, R.; Redjel, B.

    2004-11-01

    Le stockage de produits chimiques dans du béton présente souvent des problèmes de durabilité dus aux attaques chimiques. Inévitablement les concentrations élevées sont les plus dangereuses. Le but de notre étude est de déterminer les changements de phases qui apparaissent dans le béton lorsqu'on substitue une partie du ciment par du laitier de haut fourneaux. Les échantillons sont conservés dans des solutions acides différents anions (HCl, H{2}SO{4}, H{3}PO{4} et CH{3}COOH) et différentes concentrations (0,1; 0,25 et 0,5M). Les formations qui apparaissent sont déterminées par diffraction X et observées au MEB. Les solutions sulfatiques conduisent à une formation de gypse en surface et d'ettringite au contact de la matrice cimentaire. Avec l'acide acétique, il y a formation de calcium acétate hydrate sous forme spongieuse tandis que, avec l'acide phosphatique, la formation de calcium hydrogeno phosphate hydrate est très superficielle.

    2012-12-01

    Suite au colloque sur la sauvegarde du patrimoine astronomique organisé par le MAEE et la SAF, sous l'égide de l'UNESCO, qui a conduit à l'adoption de la Déclaration de Paris, les directeurs d'observatoires institutionnels qui étaient absents du colloque ont ressenti le besoin de discuter de ces conclusions prises en leur nom. L'initiative d'organiser une réunion des directeurs des Observatoires des Sciences de l'Univers (OSU) à ce sujet le 30 janvier 2012 a été prise par François Vernotte, directeur de l'Observatoire de Besançon. Le présent compte-rendu de visite résulte d'une initiative spontanée d'Emmanuel Pécontal, astronome responsable du Patrimoine à l'observatoire de Lyon, et d'Evelyne Damm, membre de la Commission Nationale de classement des Monuments Historiques (CNMH) et élue à la communauté d'agglomération des Portes de l'Essonne oû est sis l'observatoire de Camille Flammarion.

    Arabi, Hafid; Sellahi, Hicham

    2016-01-01

    L’ossification hétérotopique est une ossification pathologique des parties molles. C’est une affection bénigne, récidivante et de survenue imprévisible. On décrit le cas d’un patient, traité pour une fracture du plateau tibial gauche avec mise en place d’une plaque vissée. A deux mois de l’opération, le patient a présenté une raideur du genou gauche. Le bilan radiologique standard a révélé une ossification du ligament latéral interne (LLI), confirmée par la tomodensitométrie. On ne sait pas actuellement les facteurs déterminant l’ossification des ligaments et tendons. Bien que les cliniciens prescrivent souvent des médicaments prophylactiques tels que les anti-inflammatoires et des séances de radiothérapie pour prévenir l’ossification hétérotopique des parties molles; la physiopathologie de l’ossification hétérotopique est peu connue.

    1997-05-01

    The laser-matter interaction acting during cw 2 kW Nd:YAG laser welding of an austenitic stainless steel is studied and particulary the effects linked to the presence of a keyhole in the liquid bath. This is done in order to define parameters useful to the process modelling. The absorption factor of target has been measured in order to better understand the Nd:YAG laser/stainless steel 304 interaction. Then an experimental approach of the keyhole angle value determination is proposed. Values are presented showing the important keyhole angle at the bottom of the bead. Finally a study relative to the plume above the keyhole shows that it is responsible for the formation of the nail-head part, observed on the experimental melting zone, by laser beam scattering. L'interaction laser-matière se produisant lors du soudage par laser Nd:YAG continu de 2kW d'un acier inoxydable austénitique est étudiée, et notamment les effets liés à la présence du capillaire dans le bain liquide, de façon à définir les paramètres utiles à la modélisation du processus. Le facteur d'absorption des cibles utilisées a été mesuré afin de mieux appréhender l'interaction laser Nd:YAG/acier inoxydable austénitique 304. Puis une approche expérimentale de détermination de l'angle d'inclinaison du capillaire est proposée. Des valeurs sont présentées montrant la forte inclinaison du capillaire en fond de cordon. Finalement une étude relative au panache présent audessus du capillaire met en évidence qu'il est responsable de la formation de la partie en tête de clou observée sur les zones fondues expérimentales par diffusion du faisceau laser

    2012-11-01

    To study the effect of pseudolaric acid B (PLAB) on cell proliferation and cycle of human prostate carcinoma DU-145 cells. method: Its inhibitory effect on the cell growth was measured by MTT method. Characteristics of cell death were determined by Hoechest 33342 staining. The cell cycle was detected by flow cytometry. The expressions of cyclin B1, cyclin D1 and CDK1 were detected by Real time-PCR and Western blot, respectively. PLAB notably inhibited DU-145 cell growth in a dose- and time dependent manner (P < 0.05). Its IC50 values of PLAB for DU-145 cells for 24, 48 and 72 h were 4.53, 2.39 and 2.08 micromol x L(-1), respectively. Having been treated with 5 micromol x L(-1) PLAB for 24 h, the cells showed such apoptosis characteristics as nuclei chromatin condensation and apoptotic body. With the increase in PLAB concentration, the proportion of G2/M phase cells strikingly increased in a dose- and time dependent manner (P < 0.05), meanwhile cyclin B1 and CDK1 showed over-expressions (P < 0.05), and the cyclin D1 showed under-expression (P < 0.05). PLAB can inhibit the growth of DU-145 cells and induce the cell cycle G2/M arrest, accompanied with the over-expression of cyclin B1 and CDK1, which may be related with its regulation cycle-associated protein degradation.

    Les lésions hépatiques nodulaires sont majoritairement tumorales. Le nodule nécrotique solitire du foie est rare. Le diagnostic preopératoire est difficile. Il s'agit d'une femme âgée de 43 ans qui était opérée d'un adénocarcinome du rectum métastatique au foie opéré. Le scanner abdominal de surveillance a révélé un nodule hépatique d'allure métastatique. Le second cas est celui d'un homme de 56 ans, admis pour cholécystectomie avec découverte per-opératoire d'un nodule hépatique. Dans les deux cas, le nodule hépatique était sous capsulaire et a été réséqué. L'examen anatomopathologique posait le diagnostic de nodule nécrotique solitaire du foie. Le nodule nécrotique non spécifique du foie est une lésion qui doit être évoquée, même dans un contexte néoplasique.

    2003-06-01

    We report a full-term male infant born to nonconsanguinous parents who had clinical features of Goldenhar syndrome and cri du chat syndrome. At birth, the infant was noted to have dysmorphic features with bilateral preauricular tags, rotated ears, bilateral epicanthic folds, a left epibulbar lipodermoid, and an accessory left nipple. After he was assessed for feeding difficulty and tachypnea, he was found to have esophageal atresia with tracheoesophageal fistula. In addition, he had a high-pitched, cat-like cry, characteristic of cri-du-chat syndrome. He also failed a hearing test. Chromosomal analysis and fluorescence in situ hybridisation studies showed an unbalanced karyotype with a terminal deletion of the segment p14 on the short arm of chromosome 5, which is consistent with the cri-du-chat locus. The association of Goldenhar syndrome and cri-du-chat syndrome in this patient suggests that the chromosome 5p14 locus may harbor a gene implicated with Goldenhar syndrome.

    Oxypeucedanin has been reported to have various biological activities. We investigated the efficacy of a coumarin compound, oxypeucedanin, from Ostericum koreanum against the human prostate carcinoma cell line DU145. Oxypeucedanin (C(16)H(14)O(5), mw: 286) was isolated through silica gel chromatography and characterized by NMR. The cells were treated with oxypeucedanin (25, 50, and 100 microM) for 24-72 hours, and cell growth and death were then assayed. The cell cycle progression and apoptotic effects were also assessed by western blotting. Treatment with oxypeucedanin inhibited cell growth and induced cell death in DU145 cells. Furthermore, oxypeucedanin-induced cell growth inhibition was associated with an increase in G2-M arrest in cell cycle progression in DU145 cells in a dose and time-dependent manner. G2-M arrest by oxypeucedanin was associated with decreased levels of cyclin A, cyclin B1, Cdc2, and pCdc2. Oxypeucedanin-induced cell death was associated with significant increases in apoptosis and cleaved caspase-3 and poly-(ADP-ribose) polymerase. These finding suggest a novel anticancer effect for oxypeucedanin, mediated via induction of G2-M cell cycle arrest and apoptosis in human prostate carcinoma DU145 cells.

  15. Effects of DU-6859a, a New Quinolone Antimicrobial, on Theophylline Metabolism in In Vitro and In Vivo Studies

    1998-01-01

    In vitro and in vivo studies were conducted to investigate the drug interaction between a new quinolone antimicrobial, DU-6859a, and theophylline (TP). The effect of DU-6859a on TP metabolism was evaluated in vitro by measuring the rate of TP metabolite formation by using human liver microsomes. DU-6859a inhibited the metabolism of TP, especially the formation of 1-methylxanthine, in vitro, but to a lesser extent than other drugs that are known to interact with TP. TP was administered alone (200 mg twice a day [b.i.d.] for 9 days) or in combination with DU-6859a (50 or 100 mg b.i.d. for 5 days) to six healthy subjects. DU-6859a administered at a dose of 50 mg resulted in no changes in serum TP concentrations, and slight increases in serum TP concentrations were observed at a dose of 100 mg. Moreover, the administration of 100 mg of DU-6859a resulted in decreases in all urinary TP metabolites, with significant differences. It appears that although DU-6859a has a weak inhibitory effect on TP metabolism in vitro, its concomitant use with TP at clinical dosage levels does not cause any adverse effects, showing only a slight increase in blood TP concentrations and a decrease in urinary metabolites.

    Résumé Problème: Le dépistage VIH chez les enfants a rarement été au centre des préoccupations des chercheurs. Quand le dépistage pédiatrique a retenu l'attention, cela a été pour éclairer seulement sur les performances diagnostiques en ignorant même que le test pédiatrique comme bien d'autres peut s'accepter ou se refuser. Cet article met au cœur de son analyse les raisons qui peuvent expliquer qu'on accepte ou qu'on refuse de faire dépister son enfant. Objectif: Etudier chez les parents, les mères, les facteurs explicatifs de l'acceptabilité du test VIH des nourrissons de moins de six mois. Méthodes: Entretien semi-directif à passages répétés avec les parents de nourrissons de moins de six mois dans les formations sanitaires pour la pesée/vaccination et les consultations pédiatriques avec proposition systématique d'un test VIH pour leur nourrisson. Résultats: Nous retenons que la réalisation effective du test pédiatrique du VIH chez le nourrisson repose sur trois éléments. Primo, le personnel de santé par son discours (qui dénote de ses connaissances et perceptions même sur l'infection) orienté vers les mères influence leur acceptation ou non du test. Secundo, la mère qui par ses connaissances et perceptions même sur le VIH, dont le statut particulier, l'impression de bien-être chez elle et son enfant influence toute réalisation du test pédiatrique VIH. Tertio, l'environnement conjugal de la mère, particulièrement caractérisé par les rapports au sein du couple, sur la facilité de parler du test VIH et sa réalisation chez les deux parents ou chez la mère seulement sont autant de facteurs qui influencent la réalisation effective du dépistage du VIH chez l'enfant. Le principe préventif du VIH, et le désir de faire tester l'enfant ne suffisent pas à eux seuls pour aboutir à sa réalisation effective, selon certaines mères confrontées au refus du conjoint. A l'opposé, les autres mères refusant la r

    Introduction Dans notre milieu, il n'existe aucune politique de prévention du Retard de Croissance Intra-Utérin (RCIU) clairement défini. L'objectif de ce travail était d'identifier les facteurs de risque de RCIU afin de proposer une stratégie de lutte contre cette pathologie en agissant surtout sur des facteurs pouvant faire l'objet d'une action préventive. Méthodes Une étude cas-témoins a été menée dans 11 centres hospitaliers de Lubumbashi en République Démocratique du Congo, de Janvier 2010 à Juin 2011, dans le but d'identifier les facteurs de risque du retard de croissance intra-utérin (RCIU). Au total 420 gestantes (cas et témoins) avec grossesse monofoetale d'au moins 24 semaines d'aménorrhée ont été inclues dans l'étude. Les cas correspondaient aux gestantes dont le poids du fœtus était resté inférieur au 10 eme percentile des courbes de référence d'Alexander, après 2 échographies successives réalisées à intervalle de 4 semaines. Les témoins correspondaient aux gestantes dont le poids du fœtus était supérieur ou égal au 10 eme percentile de mêmes courbes. A chaque cas a été apparié un témoin de même parité porteur d'une grossesse de même âge. Résultats L'analyse univariée a identifié comme facteurs de risque: la taille maternelle. Conclusion L'amélioration du niveau socio-économique des populations, la lutte contre le paludisme et les consultations prénatales mieux organisées couplées à une meilleure éducation sanitaire et nutritionnelle peuvent contribuer sensiblement à la réduction de la fréquence du RCIU à Lubumbashi.

  18. Mesure de haute resolution de la fonction de distribution radiale du silicium amorphe pur

    NASA Astrophysics Data System (ADS)

    Laaziri, Khalid

    1999-11-01

    Cette these porte sur l'etude de la structure du silicium amorphe prepare par irradiation ionique. Elle presente des mesures de diffraction de rayons X sur de la poudre de silicium cristallin, du silicium amorphe relaxe et non relaxe, ainsi que tous les developpements mathematiques et physiques necessaires pour extraire la fonction de distribution radiale correspondant a chaque echantillon. Au Chapitre I, nous presentons une methode de fabrication de membranes minces de silicium amorphe pur. Il y a deux etapes majeures lors du processus de fabrication: l'implantation ionique, afin de creer une couche amorphe de plusieurs microns et l'attaque chimique, pour enlever le reste du materiau cristallin. Nous avons caracterise premierement les membranes de silicium amorphe par spectroscopie Raman pour verifier qu'il ne reste plus de trace de materiau cristallin dans les films amorphes. Une deuxieme caracterisation par detection de recul elastique (ERD-TOF) sur ces memes membranes a montre qu'il y a moins de 0.1% atomique de contaminants tels que l'oxygene, le carbone, et l'hydrogene. Au Chapitre II, nous proposons une nouvelle methode de correction de la contribution inelastique "Compton" des spectres de diffusion totale afin d'extraire les pics de diffusion elastique, responsable de la diffraction de Bragg. L'article presente tout d'abord une description simplifiee d'une theorie sur la diffusion inelastique dite "Impulse Approximation" (IA) qui permet de calculer des profils de Compton en fonction de l'energie et de l'angle de diffusion 2theta. Ces profils sont utilises comme fonction de lissage de la diffusion Compton experimentale. Pour lisser les pics de diffusion elastique, nous avons utilise une fonction pic de nature asymetrique. Aux Chapitre III, nous exposons de maniere detaillee les resultats des experiences de diffraction de rayons X sur les membranes de silicium amorphe et la poudre de silicium cristallin que nous avons preparees. Nous abordons aussi les
