    La fabrication des composants en verre optique nécessite des moyens de grande précision dans les procédés de finition vue l'importance accordée à leur qualité.
Durant le processus de polissage des verres optiques, le polissoir est un élément clé et a un impact direct sur les performances des composants optiques, non seulement il est utilisé comme support de grains abrasifs mais il doit posséder la fonction de transmission de la pression aux grains. La connaissance de ses propriétés, essentiellement mécanique, est impérative afin d'obtenir un état de surface optimal des composants optiques destinés à remplir des fonctions très précises dans des appareils optiques très performants.
Dans cette étude, nous avons constaté que les propriétés des polissoirs en polyuréthanne tel que la dureté, le module d'élasticité et la densité varient au cours du polissage. Ce changement a des effets sur l'état de surface de verre optique, causé par le changement microstructural de la surface du polissoir (distribution et dimensions des pores) et par conséquent sur la quantité des abrasifs (en oxyde de cérium) insérée dans les pores, ce qui influe sur la quantité de verre enlevée et sur l'état de surface du composant.
Sur la base des résultats obtenus, il a été prouvé que le polissoir subit des modifications très importantes ce qui influe considérablement sur son efficacité de polissage.

    Optical fibres are widely used as physical and mechanical sensors in various matrices. Those commercial available fibres are mostly coated with different polymers (e.g. polyimide). The problem of using such coatings is the undefined adhesion and the stress transmission from the matrix material into the fibre as well as the alkaline attack from the cementitious environments onto the glass surface. Therefore the known silanisation process with alkylsilanes for surface modification was studied. To achieve a silane film onto the fibre surface as close as possible a fibre pre-treatment in oxygen plasma was applied. The wetting behaviour of the oxygen plasma treated fibres as well as the silanized fibres were studied using the Wilhelmy-method. The influence of the silane concentration and the time of the pre-treatment on the wetting properties was investigated. By scanning electron microscopy, changes of the surface morphology were detected. Additionally, the mechanical properties of the oxygen plasma treated fibres, and silanized fibres exposed to a highly alkaline pore solution were measured. For selected fibre samples (decoated and untreated as well as silanized fibres) the adhesion to a concrete matrix was studied using the indention test. Les fibres optiques sont de plus en plus utilisées comme capteurs des propriétés physiques et mécaniques de nombreuses matrices. Ces fibres commerciales sont généralement enrobées avec différents polymères (par exemple polyimide). Les problèmes dus à l'enrobage des fibres optiques sont une adhésion et une transmission de charge de la matrice du béton à la fibre non définies. Un autre problème majeur est l'alcalinité du béton et son influence sur la surface de la fibre. Nous avons utilisé le procédé de silanisation. Pour obtenir un film de silane le plus homogène possible sur la surface, les fibres sont pré-traitées par le plasma d?oxygène. Le mouillage de fibres traitées par le plasma d?oxygène, ainsi que

    Introduction Analyse du profil bactériologique des pieds diabétiques pris en charge à l'hôpital militaire de Rabat et son influence sur l'antibiothérapie de première intention. Méthodes Etude prospective non randomisée étalée sur 18 mois, ayant concerné 105 patients. Après recueil des données et en attente des résultats bactériologiques nos patients ont été divisés en deux groupes: un groupe a été mis sous Amoxicilline + Acide clavulanique + Gentamycine (59 patients) et un groupe sous Ertapénème±Gentamycine (46 patients). Résultats L’étude a regroupé 85 hommes et 20 femmes (sexe ratio = 4.26). L’âge moyen est de 64.4 ans. La gangrène a été observée chez 79% des malades; elle était humide-donc surinfectée en principe- dans 43% des cas. Par ailleurs, 67% des malades ont un chiffre de globules blancs 12000 définissant une infection sévère. L'ostéolyse a été mise en évidence chez 27% de nos patients. Parmi les différentes techniques de prélèvements: 81% ont été profonds dont 21% de biopsie osseuse per opératoire et 14% de prélèvements combinés. 42% de ces prélèvements sont poly microbiens et 21% sont stériles. Les résultats bactériologiques viennent confirmer la prédominance des bactéries aérobies à Gram positif. Le taux de remplacement de l'Ertapénème est de 22% contre un taux de 50% pour l'Amoxiclav. Conclusion L'antibiothérapie ne doit être instaurée qu'en cas d'infection du pied diabétique diagnostiquée sur les critères cliniques établis par les consensus internationaux récents. Le respect des mesures de lutte contre la diffusion de la résistance bactérienne s'avère primordiale. PMID:27386024

  4. La diffraction des neutrons et des rayons X pour l'étude structurale des liquides et des verres

    La compréhension de mainte propriété physique d'un verre ou d'un liquide nécessite la connaissance des facteurs de structure partiels (PSFs) qui décrivent chacun la distribution d'une espèce atomique autour d'une autre. La technique de diffraction des neutrons avec substitution isotopique (NDIS) [1,2,3], ayant bien réussi a déterminer les PSFs de certains composés [4,5], est pourtant restreinte aux isotopes présentant un contraste suffisant en longueur de diffusion. D'un autre cote, la technique de diffusion anomale des rayons X (AXS ou AXD) [6] permet de faire varier la longueur de diffusion d'une espèce atomique pourvu que son énergie d'absorption soit à la fois accessible et suffisamment élevée pour donner un assez grand transfert du moment. La combinaison des techniques de diffraction des neutrons (avec ou sans substitution isotopique) et de diffraction des rayons X (avec ou sans diffusion anomale) peut donc permettre d'obtenir un meilleur contraste en longueurs de diffusion pour un système donné, mais exige une analyse de données plus soignée pour pouvoir bien tenir compte des erreurs systématiques qui sont différentes pour les 2 techniques [7]. Pour les atomes ayant des distributions électroniques quasi-sphériques, e.g. dans le cas d'un alliage liquide, la combinaison des techniques de NDIS et de diffraction des rayons X s'est déjà montrée très avantageuse pour la détermination des PSFs [8,9]. Dans le cas des verres ayant d'importantes liaisons covalentes, l'effective combinaison des 2 techniques peut être moins directe mais facilitée lorsqu'il s'agit des atomes de grand Z [10,11]. Nous présentons ici un sommaire du méthode et quelques exemples des résultats.

    The Nam Con Son basin is the largest oil and gas bearing basin in Vietnam, and has a number of producing fields. The history of studies in the basin can be divided into four periods: Pre-1975, 1976-1980, 1981-1989, and 1990-present. A number of oil companies have carried out geological and geophysical studies and conducted drilling activities in the basin. These include ONGC, Enterprise Oil, BP, Shell, Petro-Canada, IPL, Lasmo, etc. Pre-Tertiary formations comprise quartz diorites, granodiorites, and metamorphic rocks of Mesozoic age. Cenozoic rocks include those of the Cau Formation (Oligocene and older), Dua Formation (lower Miocene), Thong-Mang Cau Formation (middle Miocene), Nam Con Son Formation (upper Miocene) and Bien Dong Formation (Pliocene-Quaternary). The basement is composed of pre-Cenozoic formations. Three fault systems are evident in the basin: north-south fault system, northeast-southwest fault system, and east-west fault system. Four tectonic zones can also be distinguished: western differentiated zone, northern differentiated zone, Dua-Natuna high zone, and eastern trough zone.

    The purpose of this study was to examine the relationship between fathers' influences and African American male adolescents' perceptions of self-efficacy to reduce high-risk sexual behavior. A convenience sample of 70 fathers was recruited from churches in a large metropolitan area in the South. Hierarchical multiple linear regression analysis indicated father-related factors and son-related factors were associated with 26.1% of the variance in son's self-efficacy to be abstinent. In the regression model greater son's perception of the communication of sexual standards and greater father's perception of his son's self-efficacy were significantly related to greater son's self-efficacy for abstinence. The second regression model with son's self-efficacy for safer sex as the criterion was not statistically significant. Data support the need for fathers to express confidence in their sons' ability to be abstinent or practice safer sex and to communicate with their sons regarding sexual issues and standards.

  12. Polygyny: insufficient father-son contact and son's masculine identity.

    PubMed

    Kitahara, M

    1976-05-01

    In polygynous societies in which the family consists of husband, wives, and children only, if each cowife lives in a separate quarter with her children, males are more likely to be circumcised or segregated at puberty. These customs are interpreted as the measures to rectify boys' mother-oriented personality development because of limited contact with their fathers due to their mother's separate quarters. Circumcision and segregation can be explained better in terms of the son's insufficient contact with the father rather than a very close relationship with the mother due to the long postpartum sexual taboo.

  15. Preference for sons: past and present.

    PubMed

    Li, D

    1997-10-01

    This brief article discusses the present and past preference for sons in China. The preference for sons is rooted in feudal views that men are superior to women. Preference for sons dates back to the Warring States Period, in about 500 B.C. Clan brotherhoods of men have existed for centuries. Historical records mention the practice of female infanticide. Patriarchal families believed that women were economically dependent on men and thus became their subjects. Daughters married, lived in their husband's home, and did not carry the responsibility of caring for their own parents. Couples with only daughters would seek a son-in-law to support them in old age. Rural families with no sons were looked down upon. Sons were expected to carry on the family lineage, increase the reputation of the family, and protect the family's interests. The lack of sons was a sign of humiliation and a curse. The founding of the People's Republic of China brought changes to son preference. The government attempted to increase women's status. In rural areas, women were given equal access to the land. Job opportunities were created for women during the industrialization drive. The Chinese government encouraged the repudiation of the negative impacts of the doctrines of Confucius and Mencius. Efforts were made to give men and women equal pay for equal work. Legislation was passed prohibiting arranged marriage, polygyny, and early marriage. A side effect of fertility decline is the renewed preference for sons. In Huangyan and Haining in Zhejiang, a developed province, the sex ratio at birth is normal. Sexual division of labor reinforces son preference.

  16. Father-son incest: a case report.

    PubMed

    Awad, G A

    1976-02-01

    A case of father-son incest is presented. There were three sexual involvements over a period of 6 weeks that ranged in activity from genital fondling to anal penetration. The father was the initiator of the activity and was drunk during each of the episodes. The son passively submitted while the mother denied the activity when told about it after the first episode. The marital situation had deteriorated over the years to an almost complete breakdown of communication. The father had been struggling with latent homosexuality for a long time, and the alcohol triggered the incidents. There was no evidence of any special relationship between father and son, except for the acting-out behavior and the challenging of parental authority by this particular son. Short term, behavior-oriented marital sessions helped to improve the situation at home.

    1983-06-01

    The purpose of the present study was to examine the interrelationship of the domains of father personality attributes, father socialization techniques, and adolescent personality attributes, and the son's use of tobacco. A sample of 246 male adolescents and their fathers from intact homes was administered questionnaires. Two main findings emerged. First, each of the three domains was significantly associated with the son's tobacco use despite control on the remaining domains. Second, the effectiveness of the father may interact synergistically with or be mitigated by the son's personality attributes in its association with the son's tobacco use. In concert, the findings support the importance of examining the father-son relationship for a greater understanding of the son's tobacco use.

    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

    Le fibromatosis colli (FC) est pseudotumeur rare du muscle sterno-cléido-mastoïdien (SCM), à l'origine d'un torticolis dit congénital chez le nouveau-né ou le nourrisson. Le mécanisme étio-pathogénique de sa survenue est sujet à controverse. Son diagnostic fait appel à l’échographie qui permet de mettre en évidence un épaississement caractéristique du muscle. Nous rapportons deux cas diagnostiqués par l’échographie avec pour un cas une notion de malposition intra-utérine et pour l'autre cas une absence totale de malposition et de traumatisme obstétrical qui pourtant est évoqué comme élément du mécanisme de survenue du FC.

  7. SO(N) restricted Schur polynomials

    SciTech Connect

    Kemp, Garreth

    2015-02-15

    We focus on the 1/4-BPS sector of free super Yang-Mills theory with an SO(N) gauge group. This theory has an AdS/CFT (an equivalence between a conformal field theory in d-1 dimensions and type II string theory defined on an AdS space in d-dimensions) dual in the form of type IIB string theory with AdS{sub 5}×RP{sup 5} geometry. With the aim of studying excited giant graviton dynamics, we construct an orthogonal basis for this sector of the gauge theory in this work. First, we demonstrate that the counting of states, as given by the partition function, and the counting of restricted Schur polynomials match by restricting to a particular class of Young diagram labels. We then give an explicit construction of these gauge invariant operators and evaluate their two-point function exactly. This paves the way to studying the spectral problem of these operators and their D-brane duals.

    Mitchell, Katherine Stamps; Booth, Alan; King, Valarie

    2009-01-01

    This study examined sons' and daughters' involvement with nonresident fathers and associated outcomes (N=4,663). Results indicate that sons and daughters report equal involvement with nonresident fathers on most measures of father investment, although sons report more overnight visits, sports, and movies, and feeling closer to their fathers compared to daughters. Sons and daughters generally benefit from nonresident father involvement in the same way in internalizing and externalizing problems and grades. However, feeling close to one's nonresident father is associated with lower internalizing problems for daughters than sons. These findings suggest that nonresident fathers should be encouraged to be equally involved with their sons and daughters, as such involvement is associated with higher levels of well-being for both sons and daughters.

    2012-01-01

    The study examined: (1) the intergenerational concordance between parents and their adolescent sons using the Adult Attachment Interview (AAI) categories and state-of-mind scales; and (2) the contribution of parents' state of mind with respect to attachment to their sons' adjustment during a stressful separation, as well as the possibility that sons' AAI mediates the associations between parents' AAI and sons' adjustment. Eighty-eight adolescents and their parents were interviewed using the AAI during the son's senior year in high school. Approximately a year later, during the first phase of compulsory military service, the adolescents and their peers reported on the sons' adjustment. Results demonstrated AAI correspondence between mothers' (but not fathers) and sons' categories (autonomous versus non-autonomous) and associations between mothers', fathers' and sons' AAI state-of-mind scales. The adjustment of sons of non-autonomous mothers (in particular, preoccupied mothers) was inferior to the adjustment of others. Mothers' and fathers' state of mind scales were associated with sons' adjustment, but sons' AAI did not mediate this association. The uniqueness of adolescence, the importance of parents' state of mind and the differences between mothers and fathers are discussed.

    Résumé Objectif Résumer les meilleures données portant sur les stratégies d’identification et de prise en charge des femmes qui présentent des antécédents familiaux de cancer du sein. Sources d’information Une recherche a été effectuée sur PubMed à l’aide des mots-clés anglais suivants : breast cancer, guidelines, risk, family history, management et magnetic resonance imaging screening, entre 2000 et 2016. La plupart des données sont de niveau II. Message principal Une bonne anamnèse familiale est essentielle lors de l’évaluation du risque de cancer du sein afin d’identifier les femmes qui sont candidates à une recommandation en counseling génétique pour un éventuel test génétique. On peut sauver des vies en offrant aux femmes porteuses d’une mutation au gène BRCA des interventions chirurgicales de réduction des risques (mastectomie bilatérale prophylactique, salpingo-ovariectomie bilatérale). Il faut encourager toutes les femmes qui présentent des antécédents familiaux de cancer du sein à demeurer actives et à limiter leur consommation d’alcool à moins de 1 verre par jour; certaines femmes sont admissibles à la chimioprévention. Il faut offrir aux femmes dont le risque à vie de cancer du sein est de 20 à 25 % ou plus un dépistage poussé par imagerie par résonance magnétique en plus d’une mammographie. Conclusion Une vie saine et la chimioprévention (chez les candidates) pourraient réduire l’incidence du cancer du sein; le dépistage poussé pourrait entraîner une détection plus précoce. Le fait d’aiguiller des femmes porteuses d’une mutation au BRCA vers la chirurgie de réduction des risques sauve des vies. PMID:27737991

  16. Influence du traitement thermique sur l'usinabilite du laiton monophase

    NASA Astrophysics Data System (ADS)

    Cholley, Airy

    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.

    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.

  18. Is the distant relationship of fathers and homosexual sons related to the sons' erotic preference for male partners, or to the sons' atypical gender identity, or to both?

    Study 1 compared the retrospectively reported father-son relationships of four groups of adult males: (a) Gynephiles (males who erotically prefer physically mature females), (b) androphiles (who prefer physically mature males), (c) a combined group of heterosexual pedophiles and pedohebephiles (the latter being attracted to pubescent as well as prepubescent females), and (d) a combined group of homosexual pedophiles and pedohebephiles (the latter attracted to pubescent as well as prepubescent males). The gynephiles were paid volunteers; the latter three groups were patients. The androphiles, the only group among those compared known to exhibit a measurably greater degree of cross gender identity in childhood, were also the only group to report significantly poorer father-son relations. The homosexual pedo/pedohebephiles, who also prefer male partners but who exhibit typical male gender identity in childhood, did not differ in father-son relations from the gynephiles or the heterosexual pedo/pedohebephiles. Study 2 showed that, within a sample of nonpatient volunteer androphiles, those individuals who reported the greatest degree of cross gender behavior in childhood also tended to report the worst relationships with their fathers. This correlation was replicated within a sample of androphilic patients in Study 3. The consistent pattern of results obtained from these three studies suggests that the emotionally distant relationships of fathers and androphilic sons relate to the sons' atypical childhood gender identity (or observable gender role behavior) rather than to the sons' erotic preference for male partners per se.

    Objective: To analyze desire for sons/daughters among ladies of Peshawar, Pakistan, with a view to rule out son preference and to study impact of various demographic characteristics on the subject. Methods: Cross-sectional descriptive study conducted at Combined Military Hospital, Peshawar, from August 2015 - January 2016; sampling technique was random/probability/non-purposive. Self-designed questionnaire was utilized; carrying questions pertinent to desire for sons/daughters during marital life, and demographic details. Data analyzed via descriptive analysis (SPSS-21), expressed as frequencies/percentages and mean ± standard deviation(minimum/maximum). Sons and daughters desired (dependent variables) were cross-tabulated with independent variables. Results: Response rate was 63.25% (n-506). Data revealed following: Sons desired 3.05±2.061(1/12); Daughters desired 1.15±0.767(0/4); 6.1%(n-31) and 0.6%(n-3) desired infinite number of sons and daughters respectively, 18.2%(n-92) did not desire to have even one daughter, while 2.2%(n-11) considered it immaterial to have daughters or sons. There was a significant relation between sons desired and client’s education (p<0.001), husband’s education (p<0.001) and socioeconomic class (p<0.001). There was no significant impact of religion (p-0.142) on desire for sons. Impact of independent variables on daughters desired was similar but less pronounced. Conclusion: There was candid son preference among the respondents. Gender discrimination can be attenuated by adequately addressing son preference at all tiers. PMID:27648055

    Murphy, Rachel; Tao, Ran; Lu, Xi

    2011-01-01

    This article draws on a survey conducted in six provinces in summer 2008 to investigate the determinants of son preference in rural China. The analysis confirms the conventional wisdom that son preference is embedded within patrilineal family structures and practices. We extend our analysis by exploring specific aspects of variation within patrilineal family culture. We find that the patrilineal group (clan) composition of villages and family participation in practices such as building ancestral halls and updating genealogies significantly influence son preference. Yet even though son preference is embedded within patrilineal family culture, our analysis suggests that over time the attenuation of son preference is likely. This is because determinants associated with socioeconomic change—for instance, higher levels of education, direct exposure to official policy education materials, higher income (a proxy for rural industrialization), and agricultural mechanization—all attenuate son preference. Being younger and female are also associated with weaker son preference, and both characteristics are likely to interact with education and industrialization to further dilute son preference in the longer term. Nevertheless, our findings suggest that concerted efforts are needed to ameliorate institutional discrimination against rural people in welfare provisioning and in labor markets, and to promote multiple dimensions of gender equality, including in land rights, wage rates, and education.

    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

  6. Evaluation de l'intergiciel de communication DDS pour son utilisation dans le domaine avionique

    Levesque-Landry, Kevin

    Les aeronefs modernes doivent combler de plus en plus de fonctionnalites afin de satisfaire les besoins de la clientele. De ce fait, les besoins en communications des systemes avioniques sont grandissants. De plus, la portabilite et la reutilisabilite des applications sont des defis d'actualite dans le domaine avionique. De ce fait, ce projet de recherche vise a faire une evaluation de la technologie d'intergiciel de service de distribution de donnees (DDS) pour son utilisation dans le domaine avionique. Cette technologie permettrait de reduire la complexite des communications et faciliter la portabilite et reutilisabilite des applications grâce a son interface standardisee. Dans ce projet de recherche, la norme DDS est tout d'abord etudiee pour cibler les fonctionnalites qui sont utiles au domaine avionique. Les differentes polices de qualite de services sont ainsi etudiees et denotent la flexibilite de la technologie DDS. Un intergiciel DDS est egalement evalue dans un environnement de laboratoire afin de mesurer l'impact de l'utilisation de cette technologie sur les performances de latence ainsi que sur l'utilisation de la bande passante. Les resultats montrent une faible augmentation de la latence moyenne lorsque l'intergiciel DDS est utilise. L'intergiciel DDS est egalement utilise dans une etude de cas avec un AFCS (automatic flight control system) afin de quantifier les effets de son utilisation sur une application avionique. Les resultats montrent que l'utilisation de l'intergiciel DDS n'empeche pas l'AFCS d'atteindre la stabilite, mais qu'elle ralentit l'atteinte de cette derniere. Finalement, une etude de cas est effectuee afin de valider que la technologie DDS peut etre utilisee pour construire des systemes redondants. Les resultats montrent que l'intergiciel DDS permet de faire de la redondance de reserve sans avoir un impact visible sur les performances du systeme redondant.

    This Internet-based study examined the association between Israeli parents' attributions regarding the cause of their son's homosexuality and their level of acceptance of their homosexual son. The sample (N = 57) was recruited via Internet Web sites (gay forums and support groups). Findings suggest that more essentialist (versus constructivist) causal attributions were associated with higher levels of parental acceptance. Length of time parents knew of their son's homosexual orientation predicted the degree to which their attributions were essentialist. Implications are discussed.

    The sex of surviving children is an important determinant of reproductive behaviour in South Asia in general and Pakistan in particular. This cohort study evaluates the role of the sex of children on reproductive intentions and subsequent behaviour of women in urban slums of Karachi, Pakistan. The analysis is based on two rounds of surveys conducted in 1990-91 and 1995 of a cohort of married women aged 15-49 years. The results show that pregnancies became increasingly unwanted as the number of surviving sons increased. The sex of surviving children was strongly correlated with subsequent fertility and contraceptive behaviour. However, rather than an exclusive son preference, couples strove for one or more sons and at least one surviving daughter. The policy implications of the link between overt son preference and low status of women are discussed. PMID:10812738

  12. Congruence of personality assessments within families with a schizophrenic son.

    PubMed

    Schwoon, D R; Angermeyer, M C

    1980-09-01

    Following the phenomenological approach to interaction in psychiatrically disturbed families a personality questionnaire ('Giessen Test') was used to assess the views three family members (father, mother, son) had of themselves and of each other. These views may be regarded as quite stable results of interaction processes, so that conclusions about family interaction patterns may be drawn from the level of concordance of any two of them. Comparisons were made between families in which a son had been hospitalized for the first time with a diagnosis of schizophrenia and those in which a son had been hospitalized for surgical treatment, n = 30 in each category. The psychiatric patients did not on the whole give distorted personality descriptions. But in the index families the relationship between father and son was found characteristically different from that in the control families. This fact is interpreted as a reaction of the father to the deviant behaviour of the son, who did not conform with the male sex-role expectations of the father. The father as it is could not then identify with his son as a father usually does and perhaps necessarily should. The answers of the mothers partly confirm this conclusion. With regard to the parental dyad, the findings suggest that the fathers' needs for reciprocal consideration are not met by their wives.

    1994-05-01

    Le diagramme de phases du système Ag-As-Te a été étudié par analyse thermique différentielle, diffraction de rayons X et analyse métallographique. Deux combinaisons ternaires ont été observées sur la section Ag 2Te-As 2Te 3: Ag 11AsTe 7 et AgAs 3Te 5, l'une et l'autre à décomposition péritectique de type binaire, la première à 405°C, la seconde à 331°C. La phase Ag 11AsTe 7, dont l'étude structurale est en cours de résolution, est hexagonale et isotype de Ag 11.67Te 7 (Ag 5Te 3). Elle n'est observée que dans un étroit domaine de température, entre 145 et 405°C. La triangulation et le décompte des invariants ternaires imposent l'existence d'une solution solide continue entre Ag 11.67Te 7 et Ag 11AsTe 7 avec apparition concomitante de deux domaines à deux phases. Il n'a toutefois pas été possible de confirmer l'existence de cette solution solide par mesure de la variation des paramètres en fonction de la composition, les paramètres des deux composés étant extrêmement voisins. Le réseau cristallin de la phase AgAs 3Te 5 est encore inconnu; il n'a pas, de plus, été possible d'obtenir une phase AgAsTe 2. Deux sections quasi binaires sont décrites dans ce système. Huit invariants ternaires, dont trois sont pratiquement confondus avec les invariants binaires du système Ag 2Te-As 2Te 3, sont dénombrés: trois eutectiques et cinq péritectiques. Ils sont localisés en température et en composition. Une zone de démixtion ternaire liquide-liquide est observée à partir de la monotexie binaire du système Ag-Te. Enfin, un domaine formateur de verres, extrêmement étendu, est mis en évidence au voisinage de As 2Te 3 ce qui est assez exceptionnel pour un système de tellurures.

La deuxième est celle du modélisateur, confronté à l'élaboration d'un modèle théorique dont l'écriture fait toujours appel à des caractéristiques physiques élémentaires supposées connues antérieurement et déterminées par l'expérimentation. Dans les deux cas, la mesure introduit des incertitudes se propageant dans les modèles. Une première application de ces principes porte sur l'étude d'émetteurs radiatifs dans des enceintes closes de la taille d'une pièce d'habitation. La deuxième s'intéresse à la modélisation des transferts de chaleur couplés dans un milieu semi-transparent comme le verre. Les auteurs montrent qu'il est souhaitable de vérifier la stabilité des solutions fournies par les modèles au travers de ces deux exemples, cette stabilité étant indétectable a priori.

Un total de vingt-trois prototypes de dimensions differentes; ont ete testes en flexion jusqu'a la rupture. Deux types de fibres de verre de masses lineaires differentes, ont ete utilisees afin d'evaluer l'effet du type de fibres sur le comportement a la flexion. Un nouveau montage experimental permettant de tester tous les types de poteaux en PRF a ete dimensionne et fabrique selon les recommandations decrites dans les normes ASTM D 4923-01 et ANSI C 136.20-2005. Un modele analytique base sur la theorie des poutres en elasticite lineaire est propose dans cette these. Ce modele predit avec une bonne precision le comportement experimental charge---deflexion ainsi que la deflexion maximale au sommet des poteaux en PRF; constitues de plusieurs zones de caracteristiques geometriques et mecaniques differentes. Une procedure de dimensionnement des poteaux en PRF, basee sur les resultats experimentaux obtenus dans le cadre de la presente these, est egalement proposee. Les resultats obtenus dans le cadre de la presente these permettront le developpement et l'amelioration des regles de conception utiles et pratiques a l'usage des concepteurs et des industriels du domaine des poteaux en PRF. Les retombees de cette recherche sont a la fois economiques et technologiques, car les resultats obtenus constitueront une banque de donnees qui contribueront au developpement des normes de calcul, et par consequent a l'optimisation des materiaux utilises, et serviront a valider de futurs resultats et modeles theoriques.

    Friedman, R C; Stern, L O

    1980-01-01

    This retrospective study compares memories of the father-son relationship between lifelong socially well-adjusted, non-patient homosexual and heterosexual men. No homosexual subject reported the presence of a reasonably intact, positive relationship with his father or father surrogate during preadolescent years, whereas 12 of the 17 heterosexual men did. Previous investigators have hypothesized that a constructive, supportive father-son relationship precludes the development of homosexual orientation. This hypothesis stemmed from investigation of men who in general suffered from significant global psychopathology. The data in the present investigation supports the notion that a meaningful association, which is not attributable to confounding psychopathology, exists between quality of father-son relationship during early life and male sexual orientation.

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

  4. Dr. Gu Baochang speaks out on son preference in China.

    PubMed

    Bai, F

    1995-08-01

    In an interview, Dr. Gu Baochang of China discussed the topics of son preference and the increasing male-to-female sex ratio at birth in China. Gu noted that prior to 1980 the sex ratio in China was normal but that it reached a high of 113.9 in 1989 as fertility dropped. The yearly sex ratio figures continue to be close to normal for first parity births but become increasingly unbalanced for higher order births. The reasons for this abnormal sex ratio at birth are the underreporting of female births (which is estimated to account for 50-75% of the abnormality but is decreasing), sex selective abortion (which is becoming the major factor), and the lesser influence of the infanticide of female babies. The preference for sons which persists in China, Taiwan, and the Republic of Korea is determined by the issues of family labor, elderly support, women's status, and carrying on the family line. All of these issues will be influenced by socioeconomic development, which can vary in different regions of a country. Thus, Shanghai has achieved replacement level fertility with a normal sex ratio. Also, to improve efforts at fertility transition, the evaluation of family planning programs should include the incidence of son preference, and the programs should emphasize reproductive health and women's status. The issue of son preference can be explored from a broad perspective by examining the experience of other Asian countries, some of which have normal sex ratios, others of which have excess infant and child mortality. The Chinese government is trying to curb son preference by making efforts to improve the status of women and girls and by banning the illegal use of the sonogram. Eventually, as society evolves and people become achieve economic development, a normal sex ratio and low fertility will be achieved.

  5. 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.

  8. La convergence du flux de vapeur d'eau et son potentiel comme variable hydrologique de surface

    NASA Astrophysics Data System (ADS)

    Cardin-Ouellette, Sabrina

    Hydrology is often oriented on the terrestrial branch of the hydrologic cycle. In a watershed, the amount of water vapor can change due to atmospheric transport. The horizontal convergence of the moisture flux (C) constitutes the net input of water vapor in a given region. For long time periods and on a watershed's spatial scale, the horizontal convergence of the moisture flux should equal the water runoff of the watershed region. Keeping track of C should be an interesting way of increasing the efficiency of hydrological models. The global objective of this project is to quantify the hydrological cycle in the Canadian Regional Climate Model (CRCM) to evaluate if the horizontal convergence of the moisture flux can be used as an informative variable in hydrological models. The CRCM is useful to model complex hydrologic phenomena at regional scale and calculates components of the cycle that are difficult to obtain in the field. The results show that convergence is equal to the runoff on the climatic temporal scale. The temporal annual series also shows large correlation between the runoff and the convergence (r >0.8). On the monthly time scale, the relation is not as obvious because the atmospheric and terrestrial reservoirs also hold transiting water. During winter, the monthly convergence in the Nordic watersheds is approximately equal to the variation of the snow cover. The error in the simulated hydrological balance varies between 0 and 10% on the climatic time scale. This is much less than the error obtained by similar studies using reanalyses. At this scale, the term of error is related to the semi-Lagrangian computational scheme and possibly to the correction of the hydrological balance integrated in the MRCC. Increasing error on the monthly (0 to 30%) and daily (0 to 100%) time scales is due to a 6 hours temporal gap between the averaged variables and instantaneous variables in the recording scheme of the MRCC. Keywords: Hydrologic cycle, Moisture flux convergence, Canadian regional climate model.

  9. Fathers and sons: Freud's discovery of the Oedipus complex.

    PubMed

    Fuchsman, Kenneth A

    2004-01-01

    Freud's path to the Oedipus complex reveals conceptual inconsistencies. These uncertainties concern fathers, brothers and sons, and the place of the oedipal triad within the family romance. Freud's uncovering of the Oedipus complex emerged, in large part, from his self-analysis of his childhood years in Freiberg. Freud's father was 20 years older than his third wife, and had two adult sons, all of whom lived in Freiberg. In 1897, when Freud announces the Oedipus complex, he stresses his love of his mother and jealousy of his father. Yet in 1924 Freud wrote that his adult brother, Philipp, had taken his father's place as the child's rival. The oedipal complex alters if there are four players rather than three. Freud's concept of an oedipal triangle does not adequately explain the psychological dynamics of his childhood. Fuller conceptual clarity would occur if the dynamics of the Oedipus complex were placed within the family context in which it unfolds.

    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

    Thermal, electrical, and optical properties of glass compositions situated along the "As2Se5"-Ag2Se (region I), AsSe-Ag2Se, and AsSe-Ag (region II) lines are investigated and compared. For glass compositions of region I, the glass transition temperature (Tg) and the electrical conductivity (σ) are weak (Tg = 375 ± 5 K and σ = 2,6 × 10-7 cm-1 at 294 K for a 20% concentration of silver). For glass compositions of region II, Tg and σ are higher (Tg = 420 ± 5K and σ = 8,1 × 10-6Ω;-1cm-1 at 298 K for a 20% concentration of silver). All the glasses investigated are high-resistivity and wide-gap semiconductors since their optical gap is higher than 1.4 eV. With increasing Ag content in the glasses, Tg is almost constant, the optical gap decreases slightly but the electrical conductivity increases, and the activation energy decreases.

    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

    1997-02-01

    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).

  15. 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.

    2006-08-01

    In the works of Cervantes, one can observe a detailed knowledge of dental matters. Although some of his biographers think that this is the result of the very broad cultural knowledge of this distinguished Spanish writer, the authors of this paper think differently. Having studied and analyzed many documents referring to the Cervantes family, especially those which dealt with the strong influence the teachings of Cervantes' father had on his son, we have reached the conclusion that his father must have been a 16th Century dentist.

    Epidermodysplasia verruciformis (EV) is a rare genodermatosis associated with a high risk of skin cancer. In this report, we present three Iranian brothers and their mother with extensive seborrheic keratosis-like (SK-like) viral warts. Initial facial lesions developed in the first decade and disseminated with time. The patients showed SK-like viral warts characterized by dark brown or black pigmented proliferative lesions with hyperkeratotic surfaces. The histopathological findings were consistent with the diagnosis of EV. There are few reports of familial epidermodysplasia verruciformis especially in a mother and her three sons.

    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.

    2008-12-01

    Smoking during pregnancy has been reported to alter levels of reproductive hormones in adult sons. From a Danish pregnancy cohort established in 1984-1987, 347 out of 5109 sons were selected according to their exposure to tobacco smoke in foetal life. From February 2005 to January 2006, a blood sample from each young man (18-21 years) was collected and analysed for reproductive hormones. There were no apparent trends of increasing or decreasing hormonal levels with increased exposure to maternal tobacco smoking during pregnancy. Only the free testosterone/free estradiol ratios increased with increased maternal smoking during pregnancy (p for trend = 0.05). No trends for increasing odds ratios for high follicle-stimulating hormone (> or =25 percentile) or low inhibin B (< or =25 percentile) in relation to maternal smoking were observed. We found no major indication of long-term effects of pre-natal exposure to tobacco smoke on the levels of reproductive hormones later in life, but the data may suggest a shift in the hypothalamo-pituitary-gonadal axis towards higher androgenicity. This result was, however, of only borderline significance and could be because of chance.

  2. Becoming the Parent of a GLB Son or Daughter

    2014-01-01

    Recent research has documented the importance of parental reactions to disclosure for sexual minority youth (SMY) (e.g., Ryan, Huebner, Diaz, & Sanchez, 2009). The purpose of this study was to develop a deeper understanding of the parent perspective of the disclosure to family experience of SMY ages 14-21. In-depth interviews were conducted with eight parents in the United States who had experienced a child disclose their lesbian, gay, or bisexual (LGB) orientation to them. Constructivist grounded theory and symbolic interaction theory informed the methodology and data analysis for the project. Analysis revealed that the process of becoming the parent of an LGB son or daughter is an appropriate narrative to conceptualize the parental experience of the disclosure to family process. The findings highlight how disclosure introduces new roles into the existing family system, which affects the consideration and interpretation of the salience of particular identities, such as being the parent of an LGB son or daughter. Understanding how parents experience the disclosure to family process - particularly, how they understand and re-envision the meaning of being a parent - is crucial for research and intervention to help families become supportive of SMY. Limitations and suggestions for future research are presented. PMID:25685111

    Guilmoto, Christophe Z

    2012-01-01

    This article examines the recent rise in the sex ratio at birth in Vietnam and relates its emergence to kinship systems and ethnic composition using 2009 census micro-data. Presentation of the main socioeconomic and ethnic differentials in birth masculinity is followed by a review of the three intermediate factors leading to increases in the sex ratio at birth: prenatal technology, declining fertility, and gender bias. An indirect measurement of fertility behavior is used to demonstrate the close association between levels of the sex ratio at birth and the intensity of son preference. Data on household composition indicate that Vietnam is characterized by the co-existence of kinship patterns typical of East and Southeast Asia. Son preference in Vietnam is found to be related to the prevalence of more traditional patrilineal systems. The article concludes by considering the implications of the cultural dimensions of prenatal sex selection for policy responses and for the likely future change in the sex ratio at birth.

    Helium behavior in a sodium borosilicate glass (SON68) dedicated to the immobilization of high-level nuclear waste is examined. Two experimental approaches on nonradioactive glass specimens are implemented: pressurized helium infusion experiments and {sup 3}He ion implantation experiments. The temperature variation of helium solubility in SON68 glass was determined and analyzed with the harmonic oscillator model to determine values of the energy of interaction E(0) at the host sites (about -4000 J/mol), the vibration frequency (about 1.7 x 10{sup 11} s{sup -1}), and the density of solubility sites (2.2 x 10{sup 21} sites cm{sup -3}). The implantation experiments show that a non diffusive transport phenomenon (i.e., athermal diffusion) is involved in the material when the helium concentration exceeds 2.3 x 10{sup 21} He cm{sup -3}, and thus probably as soon as it exceeds the density of solubility sites accessible to helium in the glass. We propose that this transport mechanism could be associated with the relaxation of the stress gradient induced by the implanted helium profile, which is favored by the glass damage. Microstructural characterization by TEM and ESEM of glass specimens implanted with high helium concentrations showed a homogeneous microstructure free of bubbles, pores, or cracking at a scale of 10 nm.

    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

    L'adénocarcinome mésonéphrique du vagin est une tumeur maligne extrêmement rare avec uniquement trois cas publiés dans la littérature jusqu’à maintenant. Il dérive des reliquats embryonnaires des canaux mésonéphriques au niveau du vagin. Nous rapportons un cas d'adénocarcinome mésonéphrique du vagin survenant chez une femme de 50 ans, et révélé par une masse polyploïde du vagin. L'IRM a montré un envahissement du périnée et de la branche inférieure du pubis. L’étude anatomo-pathologique était en faveur d'un adénocarcinome mésonéphrique dont les cellules tumorales expriment la pancytokératine et le CD10. Elles ne sont pas marquées par les anticorps anti récepteurs ostrogéniques et progestatifs. La patiente a été adressée pour radiothérapie avant la prise en charge chirurgicale. Les auteurs soulignent à travers cette observation les aspects étiopathogéniques, histologiques et thérapeutiques de cette tumeur rare. PMID:26327963

    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

    SysSon is a research approach on introducing sonification systematically to a scientific community where it is not yet commonly used - e.g., in climate science. Thereby, both technical and socio-cultural barriers have to be met. The approach was further developed with climate scientists, who participated in contextual inquiries, usability tests and a workshop of collaborative design. Following from these extensive user tests resulted our final software framework. As frontend, a graphical user interface allows climate scientists to parametrize standard sonifications with their own data sets. Additionally, an interactive shell allows to code new sonifications for users competent in sound design. The framework is a standalone desktop application, available as open source (for details see http://sysson.kug.ac.at/) and works with data in NetCDF format.

    In the ever changing field of reproductive medicine, clinics are regularly confronted with requests for novel variants of medically assisted reproduction. Particularly third-party (assisted) reproduction, which requires the involvement of an oocyte or sperm donor, is ethically and psychologically complex due to the parties involved, but nevertheless widely accepted. A particular type of third party reproduction concerns intrafamilial medically assisted reproduction (IMAR), where the donor is a family member of the recipients. In IMAR, some of the ethical and psychological issues associated with third party reproduction are intensified. The precise impact and consequences, however, remain speculative due to the lack of information regarding IMAR. Both the ESHRE Task Force on Ethics and Law and the Human Fertilization and Embryology Authority have recently highlighted the lack of information and the need for debate. In order to contribute to the discussion and knowledge on IMAR, we present a couple that recently visited our academic clinic with a request for a very particular variant of IMAR: first degree, intergenerational father-to-son sperm donation. As our academic hospital did not have experience with this variant of IMAR, our interdisciplinary Ethics Committee for Reproductive Medicine extensively discussed the request, resulting in an advisory report on the ethics of IMAR in general and father-to-son sperm donation in particular. Here, we will first present the andrological and social background of the couple and subsequently discuss the ethical considerations that led to the approval of their request. We will conclude the paper with recommendations for a morally sound practice of IMAR.

  10. Transgenerational effects of nutrition are different for sons and daughters.

    Food shortage is an important selective factor shaping animal life-history trajectories. Yet, despite its role, many aspects of the interaction between parental and offspring food environments remain unclear. In this study, we measured developmental plasticity in response to food availability over two generations and tested the relative contribution of paternal and maternal food availability to the performance of offspring reared under matched and mismatched food environments. We applied a cross-generational split-brood design using the springtail Orchesella cincta, which is found in the litter layer of temperate forests. The results show adverse effects of food limitation on several life-history traits and reproductive performance of both parental sexes. Food conditions of both parents contributed to the offspring phenotypic variation, providing evidence for transgenerational effects of diet. Parental diet influenced sons' age at maturity and daughters' weight at maturity. Specifically, being born to food-restricted parents allowed offspring to alleviate the adverse effects of food limitation, without reducing their performance under well-fed conditions. Thus, parents raised on a poor diet primed their offspring for a more efficient resource use. However, a mismatch between maternal and offspring food environments generated sex-specific adverse effects: female offspring born to well-fed mothers showed a decreased flexibility to deal with low-food conditions. Notably, these maternal effects of food availability were not observed in the sons. Finally, we found that the relationship between age and size at maturity differed between males and females and showed that offspring life-history strategies in O. cincta are primed differently by the parents.

    An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

    The objective of this study was to evaluate whether renal excretion of sodium is impaired and whether tubular reabsorption of sodium is increased in normotensive white men with a familial predisposition to develop essential hypertension. We compared 11 normotensive sons of two hypertensive parents (SOHT) with 11 normotensive sons of two normotensive parents (SONT); renal sodium handling was assessed after 1 week of low-sodium diet (10 mmol/d) and after 1 week of high-sodium diet (200 mmol/d). The SOHT were on average 5.5 years older than the SONT (46.9 +/- 5.2 [SD] vs 41.4 +/- 4.1, P = .012). On the sixth day of each diet, mean urinary sodium excretion did not differ between the two groups (12.9 +/- 6.3 vs 12.7 +/- 6.7 mmol/d on low-sodium diet, P = .930; 197 +/- 25 vs 200 +/- 27 mmol/d on high-sodium diet, P = .817). On the seventh day of each diet, baseline means for filtered load of sodium, absolute excretion of sodium, fractional excretion of sodium (an index of total tubular sodium reabsorption), and fractional excretion of lithium (an inverse index of proximal tubular sodium reabsorption) also did not differ between the groups. To assess renal sodium handling under non-steady-state conditions, we infused 2 L normal saline intravenously over a 2-hour period. The means for absolute excretion of sodium, fractional excretion of sodium, and fractional excretion of lithium increased from baseline, but the increases did not differ in magnitude between the groups.(ABSTRACT TRUNCATED AT 250 WORDS)

    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 delta-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. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable progress has been made

    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.

  19. Son preference in Pakistan: an analysis of intentions vs. behavior.

    PubMed

    De Tray, D

    1984-01-01

    The study assesses the extent to which the very strong expressed preference for sons in Pakistan influences couples' actual fertility behavior. Several fertility measures and estimation techniques were used to determine whether subsequent fertility behavior is influenced by the sex composition of previous births. Khan and Sirageldin's work on sex preference and desires for additional children in Pakistan were reviewed, followed by consideration of several methods of testing the relationship between sex of children and subsequent fertility and presentation of the results of several other tests of the hypothesis that sex composition of children affects actual fertility behavior. The Khan and Sirageldin (1977) results can be translated into a stopping rule which states that the higher the proportion of boys in a family, the less likely a couple is to go on to have another child. This finding, based on intentions, conflicts with the results based on actual behavior presented here. The Khan and Sirageldin results were extended by assessing the extent to which couples translated their very strong expressed preferences for sons into actual behavior. This extension was based on a sample of women, most of whom have completed fertility (all were aged 35 or older) and all of whom had at least 1 live birth. No overall relationship was found between the sex composition of children and subsequent fertility behavior. At least 2 explanations are possible for this inconsistency between intentions and behavior with each having a different implication for population policy and for the future of population growth in general. The first explanation is that in traditional societies such as Pakistan couples are unable to control their fertility adequately. The policy implications of this view suggest family planning and contraceptive distribution programs aimed at reducing the cost of achieving whatever desired family size couples want. Another explanation is that although parents

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.

    The father-son dyad might be the most socially significant male-male relationship in the life course, yet its negative qualities have been the sole focus in most research on the relationship. One communicative aspect that has received little scholarly attention is the expression of affection between fathers and sons, despite the strong correlation of affectionate communication with positive involvement, closeness, and relational satisfaction for fathers and sons. In 2 studies, the authors tested hypotheses about father-son affection that were derived from affection exchange theory (K. Floyd, in press). Results indicated that U.S. men are more affectionate with biological sons than with stepsons or adopted sons and that they are more affectionate with their biological sons than their biological sons are with them.

    This study compared sons of male alcoholics (SOMAs) who had no problems with those who were abusing substances, those who had school problems, those who were delinquent and those who were multiproblem. Corresponding groups of non-SOMAs were also included. Groups were compared at ages 6, 10, 12 and 14 years on teacher- and peer-rated aggressiveness, hyperactivity, inattention, anxiety and prosociality; parent-rated temperament; parents' disciplinary practices; school performance; family socio-economic status; self-reported substance (ab)use and delinquency; and school performance (from school records). Differences between SOMAs and non-SOMAs were small. According to teachers and peers, no problem SOMAs and non-SOMAs were less aggressive-oppositional, inattentive and hyperactive than problem SOMAs and non-SOMAs. These effects differed as a function of age, however. Also, no problem SOMAs and non-SOMAs performed better in school than boys in the problem groups. We discuss the relevance of these findings for identifying factors that render children resilient and for early screening to select truly at risk SOMAs for prevention programs.

  5. New discoveries of old SON: a link between RNA splicing and cancer.

    Hickey, Christopher J; Kim, Jung-Hyun; Ahn, Eun-Young Erin

    2014-02-01

    The SON protein is a ubiquitously expressed DNA- and RNA-binding protein primarily localized to nuclear speckles. Although several early studies implicated SON in DNA-binding, tumorigenesis and apoptosis, functional significance of this protein had not been recognized until recent studies discovered SON as a novel RNA splicing co-factor. During constitutive RNA splicing, SON ensures efficient intron removal from the transcripts containing suboptimal splice sites. Importantly, SON-mediated splicing is required for proper processing of selective transcripts related to cell cycle, microtubules, centrosome maintenance, and genome stability. Moreover, SON regulates alternative splicing of RNAs from the genes involved in apoptosis and epigenetic modification. In addition to the role in RNA splicing, SON has an ability to suppress transcriptional activation at certain promoter/enhancer DNA sequences. Considering the multiple SON target genes which are directly involved in cell proliferation, genome stability and chromatin modifications, SON is an emerging player in gene regulation during cancer development and progression. Here, we summarize available information from several early studies on SON, and highlight recent discoveries describing molecular mechanisms of SON-mediated gene regulation. We propose that our future effort on better understanding of diverse SON functions would reveal novel targets for cancer therapy.

    Climate data provide a challenging working basis for sonification. Both model data and measured data are assessed in collaboration with the Wegener Center for Climate and Global Change. The multi dimensionality and multi variety of climate data has a great potential for auditory displays. Furthermore, there is consensus on global climate change and the necessity of intensified climate research today in the scientific community and general public. Sonification provides a new means to communicate scientific results and inform a wider audience. SysSon is a user centered auditory platform for climate scientists to analyze data. It gives scientists broader insights by extracting hidden patterns and features from data that is not possible using a single modal visual interface. A variety of soundscapes to chose from lessens the fatigue that comes with repeated and sustained listening to long streams of data. Initial needs assessments and user tests made the work procedures and the terminology of climate scientists clear and informed the architecture of our system. Furthermore, experiments evaluated the sound design which led to a more advanced soundscape and improvement of the auditory display. We present a novel interactive sonification tool which combines a workspace for the scientists with a development environment for sonification models. The tool runs on different operating systems and is released as open source. In the standalone desktop application, multiple data sources can be imported, navigated and manipulated either via text or a graphical interface, including traditional plotting facilities. Sound models are built from unit generator graphs which are enhanced with matrix manipulation functions. They allow us to systematically experiment with elements known from the visual domain, such as range selections, scaling, thresholding, markers and labels. The models are organized in an extensible library, from which the user can choose and parametrize. Importance is

Sur le plan histologique, il s'agit d'une tumeur bien différenciée dont la morphologie rejoint souvent celle des carcinoïdes dans les autres localisations. Nous rapportons un cas de carcinoïde primitif du rein survenant chez un homme de 41 ans, découvert à la suite de métastases hépatiques. La tumeur était particulière par son architecture tubulo-papillaire, suggérant à tort le diagnostic de carcinome papillaire du rein. Ce diagnostic a été redressé 12 ans après, à la suite de l'apparition d'autres métastases hépatiques, osseuses et pulmonaires. PMID:27217899

    The preference for sons in deeprooted in Pakistan and the growth rate is 3.1%/year, which has long term implications for the Population Welfare Program. In this study, the relationship between living sons and contraceptive use is examined among 1243 currently married industrial workers and 307 control group workers from 13 sample industries in Karachi and Lahore, Pakistan. The Family Welfare Education for Workers' Project has been operating in these industries. Questions were asked about the number of living children by sex, desired number of children by sex, and ideal family size by sex. The ideal number of children was 4 (3.7) with an average of 2.2 sons and 1.5 daughters, which indicates son preference. Average desired children (living plus additional wanted) is 5.0 (4.7) with an average of 2.6 for sons and 2.1 for daughters. All workers with an ideal of 1 wanted a son. 90% of those wanting an ideal of 2 children desired 1 son and 1 daughter. 95% with an ideal of 3 children wanted 2 sons and 1 daughter. 83% with an ideal of 4 children desired 2 sons and 2 daughters, and 16% wanted 3 sons and 1 daughter. 85% with an ideal of 5 children wanted 3 sons and 2 daughters. Further evidence for son preference occurs with total desired number of children; i.e., 79% of those desiring 2 children preferred 1 of each sex, and 21%, 2 sons. This pattern was repeated for each increase in child desired. The desire for children was also examined in terms of existing children. Workers who have more sons were less likely to desire another child; however, those with 2 living daughters desired 1.63 more children and those with 1 of each desired .85 more children. Those with 2 sons desired .67 more children. The number of additional children desired decreases with the increasing number of living children, and with increasing numbers of living sons. Desiring no more children tends to increase with an increase in number of living children, and with an increase in the number of living

    2013-11-01

    Experimental results are reported on the effect of magnesium silicate precipitation on the mechanisms and rate of borosilicate glass dissolution. Leaching experiments with SON68 glass, a borosilicate containing no Mg, were carried out in initially deionized water at 50 °C with a glass-surface-area-to-solution-volume ratio of 20,000 m-1. After 29 days of alteration the experimental conditions were modified by the addition of Mg to trigger the precipitation of Mg-silicate. Additional experiments were conducted to investigate the importance of other parameters such as pH or dissolved silica on the mechanisms of precipitation of Mg-silicates and their consequences on the glass dissolution rate. Mg-silicates precipitate immediately after Mg is added. The amount of altered glass increases with the quantity of added Mg, and is smaller when silicon is added in solution. A time lag is observed between the addition of magnesium and the resumption of glass alteration because silicon is first provided by partial dissolution of the previously formed alteration gel. It is shown that nucleation does not limit Mg-silicate precipitation. A pH above 8 is necessary for the phase to precipitate under the investigated experimental conditions. On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate. The concentration of i in solution was analyzed as well as that of boron. The quantity of i released from the glass is estimated with the assumption that i and B are released congruently at the glass dissolution front. The remained quantity of the element i is then supposed to be in the gel or in the secondary phase. In this paper, we do not make a difference between gel and hydrated glass using the same word 'gel' whereas Gin et al. [40] makes this difference. Recent papers [40,41] discussed about different key issues related to the passivation properties of the alteration layer including the hydrated glass

    Serine-arginine-rich (SR) proteins play a key role in alternative pre-mRNA splicing in eukaryotes. We recently showed that a large SR protein called Son has unique repeat motifs that are essential for maintaining the subnuclear organization of pre-mRNA processing factors in nuclear speckles. Motif analysis of Son highlights putative RNA interaction domains that suggest a direct role for Son in pre-mRNA splicing. Here, we used in situ approaches to show that Son localizes to a reporter minigene transcription site, and that RNAi-mediated Son depletion causes exon skipping on reporter transcripts at this transcription site. A genome-wide exon microarray analysis was performed to identify human transcription and splicing targets of Son. Our data show that Son-regulated splicing encompasses all known types of alternative splicing, the most common being alternative splicing of cassette exons. We confirmed that knockdown of Son leads to exon skipping in pre-mRNAs for chromatin-modifying enzymes, including ADA, HDAC6 and SetD8. This study reports a comprehensive view of human transcription and splicing targets for Son in fundamental cellular pathways such as integrin-mediated cell adhesion, cell cycle regulation, cholesterol biosynthesis, apoptosis and epigenetic regulation of gene expression.

  19. Caracterisation et transformation par hydroviscoreduction du brut lourd de Doba/Tchad: Strategie de pompage par pipeline

    Le projet de la these est defini par rapport a la recente exploitation commerciale du brut lourd de Doba, une region du Tchad, pays enclave d'ou le brut ainsi produit doit etre achemine par pipeline. Le but dans ce travail est de caracteriser ce brut et de determiner une strategie thermique de transformation en vue de reduire de la facon la plus economique, la viscosite du brut pour permettre son transport par pipeline. Concernant la partie caracterisation, nous avons utilise entre autres, un rheometre rotatif et des analyseurs (LECO CHN-2000 & LECO S-144DR Elemental Analyzers) pour evaluer respectivement la viscosite et les elements tels que C, H, N, O, S. Sur la base des methodes de transformation disponibles, nous avons determine une strategie simple de transformation thermique par hydroviscoreduction , strategie dans laquelle, la fraction legere du brut comme le naphta (80--180°C), pourrait constituer la source d'hydrogene a utiliser. Le brut de Doba, a une faible teneur en soufre (0.14%) et sa densite specifique de 0.940 a 15.6°C, soit 18.8° API, le classe parmi les bruts lourds. Outre le point initial se situant a 85°C, la distillation du brut a revele que la fraction distillant avant 250°C ne represente que 10% (v/v) et que le craquage thermique du substrat debute a 300°C. Par ailleurs, outre son caractere Newtonien, les densites specifiques de la fraction lourde de l'essence (100--200°C) et de la fraction distillant au-dessus 350°C, etant respectivement de 0.813 (0.813 > 0.800) et de 0.951 (0.930 < 0.951 < 0.975), le brut de Doba est donc de type aromatique. Les viscosites du brut et du brut desasphalte, sont respectivement de 184.4 cSt et 152.4 cSt a 50°C, suggerant que le desasphaltage ne constitue pas une methode efficace pouvant aider au pompage du brut par pipeline, d'ou la necessite de transformation. Les resultats des travaux en autoclave montrent que, si le brut doit etre traite entierement, la viscosite de 25cSt 50°C, recommandee pour le

    African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons. We conducted focus groups with 29 African-American fathers of sons ages 10-15 to explore perceived facilitators and barriers for father-son communication about sexual health. Participants were recruited from barbershops in metropolitan and rural North Carolina communities highly affected by STIs and HIV, and data were analyzed using content analysis. Three factors facilitated father-son communication: (a) fathers' acceptance of their roles and responsibilities; (b) a positive father-son relationship; and (c) fathers' ability to speak directly to their sons about sex. We also identified three barriers: (a) fathers' difficulty in initiating sexual health discussions with their sons; (b) sons' developmental readiness for sexual health information; and (c) fathers' lack of experience in talking with their own fathers about sex. These findings have implications for father-focused prevention interventions aimed at reducing risky sexual behaviors in adolescent African-American males. © 2017 Wiley Periodicals, Inc.

    This study describes a test of the Fathers and Sons Program for increasing intentions to avoid violence and reducing aggressive behaviors in 8- to 12-year-old African American boys by enhancing the parenting skills satisfaction and parenting behaviors of their nonresident fathers. The study included 158 intervention and 129 comparison group families. Structural equation model results indicated that the intervention was effective for improving fathers' parenting skills satisfaction, which was positively associated with sons' satisfaction with paternal engagement. Sons' paternal engagement satisfaction was positively associated with their intentions to avoid violence. Although aggressive behaviors were lower for comparison group sons, the intervention effectively reduced sons' aggressive behaviors indirectly by enhancing fathers' parenting behaviors. Support for family-centered youth violence prevention efforts is discussed.

    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.

    Nous avons étudié les performances laser en pompage par diode de puissance d'un nouveau cristal : le Sr3Y(BO3)3 (acronyme : BOYS), dopé à l'ytterbium. Son spectre d'émission particulièrement large en fait un matériau particulièrement prometteur pour la réalisation de lasers femtosecondes directement pompés par diode. Ses performances ont été comparées à celles d'un verre phosphate ainsi qu'à celles du cristal d' Yb:GdCOB dans les mêmes conditions. Nous démontrons que, tant du point de vue de l'efficacité laser que de la tenue aux fortes puissances, GdCOB et BOYS sont supérieurs au verre ; le BOYS est de surcroît plus accordable (sur 50 nm), mais son comportement thermique limite a priori son usage à des puissances de pompe modérées.

    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.

    2017-01-01

    Parental environment can widely influence offspring phenotype, but paternal effects in the absence of parental care remain poorly understood. We asked if protein content in the larval diet of fathers affected paternity success and gene expression in their sons. We found that males reared on high-protein diet had sons that fared better during sperm competition, suggesting that postcopulatory sexual selection is subject to transgenerational paternal effects. Moreover, immune response genes were downregulated in sons of low-protein fathers, while genes involved in metabolic and reproductive processes were upregulated. PMID:28202685

    It has been suspected that cell-cycle progression might be functionally coupled with RNA processing. However, little is known about the role of the precise splicing control in cell-cycle progression. Here, we report that SON, a large Ser/Arg (SR)-related protein, is a splicing cofactor contributing to efficient splicing of cell-cycle regulators. Downregulation of SON leads to severe impairment of spindle pole separation, microtubule dynamics, and genome integrity. These molecular defects result from inadequate RNA splicing of a specific set of cell-cycle-related genes that possess weak splice sites. Furthermore, we show that SON facilitates the interaction of SR proteins with RNA polymerase II and other key spliceosome components, suggesting its function in efficient cotranscriptional RNA processing. These results reveal a mechanism for controlling cell-cycle progression through SON-dependent constitutive splicing at suboptimal splice sites, with strong implications for its role in cancer and other human diseases.

    Because infection with human papillomavirus is a necessary cause of cervical cancer, it is likely that host immunological factors involved in defense against such infections are important for susceptibility to this cancer. By examining associations between allergy in sons and cervical cancer in their mothers, we aimed to test for genetic components involved in both allergy and cervical cancer development. Women born in Sweden between 1932 and 1960 with at least 1 son with medical records from military conscription examination were included in the study (N = 717,963). Among these women there were 41,910 in situ and 3,618 invasive cases of cervical cancer. Hazard ratios of in situ and invasive cervical cancer were estimated as functions of allergic rhinoconjunctivitis, asthma and eczema diagnoses in sons. Adjustment was made for the possible confounders: age, year of birth, education, socio-economic index, geography, number of conscripted sons and total number of offspring. The risk of in situ and invasive cervical cancer was lower for women having sons diagnosed with hypersensitivity (allergic rhinoconjunctivitis, asthma or eczema). Fully adjusted hazard ratios for women with 1 hypersensitive son were for in situ 0.86 (95% CI 0.84-0.88) and for invasive cervical cancer 0.82 (95% CI 0.74-0.91). The protective effects were similar between the 3 allergic diagnoses and increased with number of sons with a diagnosis. There was no significant association between non-cervical cancer in mothers and allergy in sons. These results strengthen the hypothesis that inherited immunological factors are important in determining risk of cervical cancer, probably by affecting mechanisms for viral persistence.

    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

  19. Like daughter, like son? Fertility decline and the transformation of gender systems in the family

    Allendorf, Keera

    2016-01-01

    BACKGROUND An important question for population research is whether fertility decline transforms gender systems. OBJECTIVE This paper contributes to answering this broad question by examining how fertility decline may change the relative value and roles of daughters and sons in families. First, I outline theoretical pathways, suggesting that a key factor is the gender composition of families. As fertility declines, the proportion of families with children of only one gender increases, which may facilitate greater gender symmetry between daughters and sons. Second, I explore how fertility decline may have contributed to the transformation of the relative value and roles of sons and daughters in practice in one place. METHODS The analysis draws primarily on semi-structured interviews with 30 respondents living in one Indian village. This village is located in a district where fertility has declined to at least the replacement level. RESULTS Respondents perceive changes in the gender system, including less son preference, more equal schooling for sons and daughters, more freedom in marriage and premarital relationships, and perhaps greater daughter support of parents in old age. CONCLUSIONS The results describe changes in the relative value, treatment, and behavior of sons and daughters that are consistent with the theorized effects of fertility decline. Future research is needed, however, to determine whether fertility decline makes a causal contribution to changes in the gender system. PMID:27147902

    La presente these s'inscrit dans le cadre d'un projet strategique sur les arenas finance par le CRSNG (Conseil de Recherche en Sciences Naturelles et en Genie du Canada) qui a pour but principal le developpement d'un outil numerique capable d'estimer et d'optimiser la consommation d'energie dans les arenas et curlings. Notre travail s'inscrit comme une suite a un travail deja realise par DAOUD et coll. (2006, 2007) qui a developpe un modele 3D (AIM) en regime transitoire de l'arena Camilien Houde a Montreal et qui calcule les flux de chaleur a travers l'enveloppe du batiment ainsi que les distributions de temperatures et d'humidite durant une annee meteorologique typique. En particulier, il calcule les flux de chaleur a travers la couche de glace dus a la convection, la radiation et la condensation. Dans un premier temps nous avons developpe un modele de la structure sous la glace (BIM) qui tient compte de sa geometrie 3D, des differentes couches, de l'effet transitoire, des gains de chaleur du sol en dessous et autour de l'arena etudie ainsi que de la temperature d'entree de la saumure dans la dalle de beton. Par la suite le BIM a ete couple le AIM. Dans la deuxieme etape, nous avons developpe un modele du systeme de refrigeration (REFSYS) en regime quasi-permanent pour l'arena etudie sur la base d'une combinaison de relations thermodynamiques, de correlations de transfert de chaleur et de relations elaborees a partir de donnees disponibles dans le catalogue du manufacturier. Enfin le couplage final entre l'AIM +BIM et le REFSYS a ete effectue sous l'interface du logiciel TRNSYS. Plusieurs etudes parametriques on ete entreprises pour evaluer les effets du climat, de la temperature de la saumure, de l'epaisseur de la glace, etc. sur la consommation energetique de l'arena. Aussi, quelques strategies pour diminuer cette consommation ont ete etudiees. Le considerable potentiel de recuperation de chaleur au niveau des condenseurs qui peut reduire l'energie requise par

    Ce memoire presente l'imbrication des elements hydroelectrique au sein du paysage de la ville de Sherbrooke entre 1880 et 1930. Nous cherchons a comprendre comment les nouveaux elements energetiques s'integrent a celui-ci et comment la population sherbrookoise se represente ces espaces transformes. Comment le paysage hydroelectrique, en tant qu'espace vu et vecu, interagit-il avec la societe sherbrookoise ? A l'interieur de cette problematique generale, nous chercherons a repondre a trois sous-questions. Quelles sont les transformations physiques et materielles engendrees par l'implantation de cette nouvelle technologie hydroelectrique sur le paysage urbain sherbrookois ? Qu'est-ce que les differents groupes valorisent au sein du paysage ? Quel sens prennent ces nouveaux paysages pour les Sherbrookois ? En effet, l'etude du developpement rapide du potentiel hydroelectrique de la riviere Magog nous amene a demontrer que l'exploitation des ressources energetiques a profondement transforme le paysage de Sherbrooke : vastes modifications du trace des cours d'eau, apparition de batiments specifiques a la production energetique, structures de distributions et infrastructures permettant l'illumination de la ville. Nous avancons aussi que differents groupes d'individus ne valorisent pas les memes elements paysagers. Finalement, nous proposons que le regard porte par les citoyens sur le paysage energetique est tributaire de l'usage qu'ils en font. Comme la fonction des elements energetiques paysagers evolue, le regard qu' ils portent vers ces structures se transforme lui aussi.

    An association between childhood aggression and risk for subsequent development of a substance abuse disorder is now well-accepted. In order to better understand the relationship between the presence of paternal substance abuse and aggression among their offspring, 10-12 year old sons of fathers with (n = 34) and without (n = 39) a history of a substance abuse disorder were contrasted on demographics, aggressivity, biological indices of reproductive maturation, and the presence of psychiatric diagnoses. In addition, personality factors, the potential for physical abuse, and psychiatric diagnoses were also ascertained among their fathers. Sons of substance-abusing fathers were found to be significantly more aggressive than sons of nonsubstance abusers. However, they also differed from comparison boys on the basis of SES and school grade attained, as well as the proportion with specific psychiatric disorders. Substance-abusing fathers differed from nonsubstance-abusing men in terms of personality factors and the presence of specific psychiatric disorders, including antisocial personality. They also showed significantly higher child abuse potential scores. A multiple regression analysis of factors contributing to aggression in the boys revealed that a paternal personality factor characterized by stress reactivity, alienation, and aggression was the most robust contributor to aggression among the boys. The boys' diagnoses of attention deficit disorder, oppositional defiant disorder, and lower household socioeconomic status were also significant predictors of aggressivity. Contrary to expectations, paternal, psychiatric diagnoses, substance abuse status, and potential for physical abuse were noncontributory. The results suggest potential mechanisms by which both aggression and risk for substance abuse may be transmitted from father to son.

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

    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

  6. History of son preference and sex selection in India and in the west.

    2003-01-01

    In the history of mankind, there was a time when women dominated the world. In due course of time, as the patriarchal societies evolved, the status of women gradually declined. Sons were preferred to daughters. In India, the Brahmin community promoted such customs and rituals, which gave more and more importance to sons eg. Lighting the funeral pyre of the father was told to be a pre-condition for salvation of his spirit. Similarly, in western civilization also women were considered to be weak. In consonance with such a mind-set man has been trying various techniques for sex-selection since antiquity eg. for acquiring a son choosing a special day, time and posture for sexual intercourse, special diet, charms and amulet and prayers etc. In Vedas also punsavana karma has been described as a technique for acquiring a son. Apart from these techniques, female infanticide has also been used as a way to create a male dominated, son-worshipping society. On development of the technique of ultrasonography as an example of progress of science and technology, man has devised a new way of killing females in womb itself, which has resulted in continuous decline in female: male sex ratio in India. To stop this, Indian Govt. promulgated PNDT Act 1994. But considering the widely prevalent practice of use of various regimen of sex-pre-selection by people as well as unscrupulous medical practitioners, Govt. of India has amended this Act (2002). Still, as authors have found in one of their studies, sex-selection drugs are being used widely by north Indians for getting a son. Here, it should be noted that sex-selection methods are being used in west also. But the perspective is different. There, it is not used for female feticide or for acquiring a son. Rather, it is more an effort towards demonstrating the control of man over the NATURE.

    Dans ce travail, nous nous sommes intéressés à la croissance de films de nitrure d'aluminium par ablation laser d'une cible d'aluminium assistée par un plasma d'azote créé par une décharge RF. Parallèlement, la spectroscopie d'émission a été largement utilisée pour le diagnostic de la plume plasma et du plasma de décharge RF afin de trouver des informations permettant de suivre le phénomène de croissance et qui seraient la signature d'un film de bonne stœchiométrie et qualité cristalline ou son contraire. Ainsi, l'étude de l'émission de la raie d'oxygène à 777nm dans le plasma d'ablation laser a permis d'expliquer le mécanisme de contamination des films par l'oxygène. De la même façon, nous nous sommes intéressés à l'émission de l'azote atomique dans la plume plasma et proche du substrat, dans la zone sombre où ces espèces participent directement à la croissance du film. Ainsi l'étude parallèle de l'influence des paramètres expérimentaux sur la qualité des films et sur la composition du plasma nous a permis d'optimiser le dispositif expérimental.

    La cardiomyopathie du péripartum ou cardiomyopathie gravidique primitive, est une entité rare et méconnue définie comme une insuffisance cardiaque systolique survenant le dernier mois de la grossesse ou les cinq premiers mois du postpartum en l'absence d'étiologie connue ou de cardiopathie préexistante. Nous rapportons l'observation d'une jeune patiente de 31 ans sans antécédents pathologiques particuliers admise pour une poussée d'insuffisance cardiaque gauche 1mois après son accouchement. Le contexte de péripartum nous a fait penser au diagnostic et a motivé la réalisation d'une Echocardiographie qui a confirmé cette entité. PMID:28154713

  9. Father/son relationship during the preschool years. An integrative review with special reference to recent Swedish findings.

    Nettelbladt, P

    1983-12-01

    This review is an attempt to integrate Anglo-American and Swedish studies on father/son relationships. The puerperal period, infancy and early childhood are surveyed. Swedish studies do not support specific stereotyped bonding in the puerperal period. The review confirms the bidirectional nature of the father/son relationship. Thus, counteridentification, i.e. the father's identification with his son, and identification during the oedipal phase, i.e. the son's identification with his father, seem to be essential components in the father/son relationship. However, studies on parent-infant behaviour indicate that different parental roles exist early in infancy. Also, attachment studies point to the specificity of the father/son relationship before the oedipal phase. It is concluded that the major importance of the father/son relationship during the preschool years is to facilitate the son's masculine identification.

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.

    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

    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

  14. Proprietes ionochromes et photochromes de derives du polythiophene

    NASA Astrophysics Data System (ADS)

    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

    This study asks parents who have children with Down syndrome how they feel about their lives so that such information could be shared with expectant couples during prenatal counseling sessions. A valid and reliable survey instrument was mailed to 4,924 households on the mailing lists of six non-profit Down syndrome organizations. Of the 2,044 respondents, 99% reported that they love their son or daughter; 97% were proud of them; 79% felt their outlook on life was more positive because of them; 5% felt embarrassed by them; and 4% regretted having them. The parents report that 95% of their sons or daughters without Down syndrome have good relationships with their siblings with Down syndrome. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with Down syndrome and indicate that their sons and daughters are great sources of love and pride.

  16. Court says mother has right to stop HIV drugs for son.

    PubMed

    1998-10-02

    A mother in Maine was charged with child neglect for refusing to administer triple combination therapy to her 4-year-old son, who is HIV positive. The mother based her decision on her own experience with monotherapy and on her older daughter's experiences of the harmful side effects of AZT. Upon her daughter's death, the mother discontinued AZT treatment for herself and her son. After the mother refused a pediatrician's suggestion to start triple combination therapy for her son, the doctor reported the mother to the Department of Human Services, who then charged her with neglect. According to Newport District Judge Douglas Clapp, the mother has shown great concern for her child, and since the relative advantages of the proposed treatment are unclear, the ultimate decision of treatment should be the mother's decision. Many AIDS advocates have stated that antiretroviral therapy has shown significant benefits and recommend that treatment decisions be reached through a trusting partnership between patients and their doctors.

    2013-01-01

    Cette étude analyse les conditions de réalisation du soutien social dans les quartiers de Saint-Henri et de la Pointe Saint-Charles, en comparant un groupe de 61 prestataires de la sécurité du revenu avec un échantillon de 21 personnes de la population vivant au-dessus du seuil de la pauvreté, et en fonction du degré de détresse dans chaque groupe. Elle vise également à décrire comment une adversité vécue par les prestataires avec ou sans détresse vient briser ou modifier le réseau de soutien. Les résultats indiquent que le réseau social est moins fiable en présence de détresse qu’en son absence, que les personnes en détresse se sont vues plus fréquemment refuser du soutien ou être abandonnées et qu’elles ont davantage de personnes nuisibles dans leur entourage. De plus, les événements vécus comportent souvent une atteinte à leur réputation, des menaces, des trahisons et des refus à un droit légitime. Les personnes en détresse sont aussi davantage isolées.

    2007-09-01

    This paper explores the factors that influence the practice of induced abortion in a very low fertility society, with particular emphasis on son preference and three distinct religions: Confucianism, Buddhism and Christianity. Using multivariate logistic regression models fitted by the generalized estimating equation (GEE) method, this paper analysed the data collected by the 2000 Korea National Fertility and Family Health Survey of 6348 married women aged 15-49 years with a total of 1217 pregnancy outcomes. The results showed that the likelihood of induced abortions in women with two or more children, compared with those with one child, was significantly influenced by the sex composition of the previous children: odds ratio (OR)=12.71 (95% CI=5.49, 29.42) for women with only son(s), and OR=3.91 (95% CI=1.67, 9.14) for women with only daughter(s). At parity two, women with two sons were much more likely to have induced abortions than women with two daughters (OR=5.88, 95% CI=2.70, 12.85). Although Buddhist women were not significantly different from Confucian women in induced abortion practice, Christian women were much less likely than Confucian women to have an induced abortion (OR=0.39, 95% CI=0.18, 0.88 for women with only sons and OR=0.44, 95% CI=0.24, 0.81 for women with two children). This suggests that even in this very low fertility society, son preference and religious affiliation are significant predictors of women's practice of induced abortion.

    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.

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

  7. Andrew Wyeth and N.C. Wyeth: a psychodynamic perspective on father and son.

    Shaw, Jon A

    2013-01-01

    This paper examines the relationship between two extraordinary artists, father and son--N.C. Wyeth (1882-1945) and Andrew Wyeth (1917-2009)--and their art. N.C. Wyeth, the father, the most famous illustrator of his day, painted scenes full of drama and action, often of men engaged in violent life and death struggles. N.C. was unable to separate from his powerful mother and yearned for his iconic father. He thought himself an artistic failure and dedicated himself to raising his children to be geniuses. The youngest son, Andrew Wyeth, who lived a "secret life," painted scenes often characterized by pathos: bleak and barren landscapes, leaden skies, tire tracks, gray framed houses, desiccated fields, and circling buzzards. In the father-son relationship, we often seen three themes perpetuated developmentally: (1) the son's identification with the innermost conflicts of his father; (2) the yearning for the iconic father of his youth; and (3) a continuation and disavowal of his father's life. These themes are played out in the relationship between Andrew Wyeth and his father.

  13. Mothers Make a Difference: Mothers Develop Weaker Bonds with Immature Sons than Daughters

    Kulik, Lars; Langos, Doreen; Widdig, Anja

    2016-01-01

    Among mammals, individuals form strong social bonds preferentially with their kin. Differences in these relationships are linked to differential kin availability due to sex-specific dispersal patterns, but there is some indication that differential bonding among sexes already occurs prior to maturation. However, little is known about how these patterns arise during individual development. Here we investigated sex differences in the development of mother-offspring bonds in rhesus macaques (Macaca mulatta). Our results revealed that mothers showed sex-biased bonding toward their offspring. Sons had a distinctly higher probability of receiving aggression from their mothers than did daughters in the first year of life, while no differences were found with respect to affiliative interactions. After the first year, probabilities of all affiliative and aggressive behaviours investigated were higher for daughters than for sons, although generally declining. Furthermore, sons spending less time with their mother and receiving more maternal aggression tended to disperse earlier. The results of our study suggest that mothers influence their bonding strength with offspring by interacting less affiliative with sons than daughters. PMID:27191403

  15. SonTek IQ Plus Velocity Index Discharge Compared to Historical Stage Discharge Curve

    NASA Astrophysics Data System (ADS)

    Jones, I.

    2014-12-01

    The SonTek IQ Plus bottom-mounted, up-looking Doppler Current meter is relatively new, low profile instrument specifically designed to measure water velocity in open channels through a wide range of conditions and water depth. The predecessor to the IQ, the SonTek Argonaut SW, is a well-established tool for measuring discharge in open channels utilizing a velocity index equation. The IQ builds upon this with velocity indexing capabilities and the addition of two skew beams and the implementation of SmartPulseHD. The SonTek IQ Plus measures velocity with 4-acoustic transducers and the water level using a fifth vertically oriented transducer integrated with a pressure sensor. This improves upon previous and other bottom-mounted, up-looking, acoustic Doppler current meters by measuring the velocity at more points across the channel using its 4-monostatic acoustic transducers. Additionally, the vertically oriented transducer measures the water level and works in conjunction with the pressure sensor to provide a highly accurate water level/stage measurement. The implementation of SmartPulseHD enables the IQ to change ping type and processing technique based on water depth and velocity, in order to provide the most accurate velocity data possible. The IQ was designed specifically for measuring open channel flow in irrigation canals and similar open channels, either by utilizing SonTek's theoretical flow algorithm or using a velocity index equation. The study presented here demonstrates data collected by an IQ installed in an irrigation canal and the discharge computed using a developed index velocity equation. These data are then compared to discharge data determined by a conventional stage discharge curve developed over many years. The data presented demonstrate the capability of the SonTek IQ to compute accurate discharge values based on an index velocity equation that was developed over a relatively short period of time.

  1. Évolution nycthémérale des composantes biochimiques du phytoplancton de la retenue du barrage Idriss premier (Fès, Maroc)

    1999-03-01

    The diel changes of the biochemical composition of the phytoplankton were studied in the Idriss first reservoir (located on the Inaouen river at thirty Km from the city of Fes, Morrocco) during September 1994. Several biomass and metabolic indicators (proteins, carbohydrates, lipids, chlorophyll a and primary production) were assessed every fourth hour over tow days (7, 8 and 9 September). Since the Protein/Carbohydrates ratio (P/C) is largely recognised as a good integrator of the metabolic functions of the cells, we examined its distribution pattern concomitantly with aforementioned parameters. The results demonstrated enhanced P/C ratios clearly indicating that nutrients were sufficiently available for growth. In addition, this index showed a diel significant variation with levels higher in the night than in the day. Moreover, these results suggest that phytoplankton species during the night used the day-synthesised carbohydrates to insure the cell metabolic functioning. The P/C presents relatively high values in proposition to the ones that have been recorded in temperate regions, and seems to be related to azotic inputs of the Inaouen river. Dans le but de parfaire nos connaissances sur le fonctionnement du sous écosystème phytoplancton, nous nous sommes intéressés à étudier son cycle nycthéméral et son métabolisme cellulaire dans la retenue du barrage Idriss premier. Cette dernière, construite sur l'Oued Inaouène, est située à une trentaine de Km de la ville de Fès. Au cours de ce cycle, les prélèvements ont été effectués selon une séquence temporelle de 4 heures pendant 48 heures, les 7, 8 et 9 septembre 1994. L'étude de l'évolution des composantes biochimiques des cellules phytoplanctoniques à savoir les protéines, les glucides et les lipides a permis de mettre en évidence des variations nycthémérales importantes. Ces variations sont d'autant plus importantes que les variations spatiales observées entre les profondeurs. De plus

  2. Origine du champ magnétique en cosmologie et formation des galaxies

    2002-12-01

    Ma thèse est le fruit d'un travail théorique centré sur deux questions fondamentales de la cosmologie actuelle: la formation des galaxies d'une part, et l'origine des champs magnétiques à grande échelle d'autre part. Je propose une solution au problème du sur-refroidissement dont souffrent les modèles de formation des galaxies. Pour cela, à l'aide d'un modèle analytique simple, puis au moyen de simulations numériques, j'explore les mécanismes de transfert et de stockage d'énergie par ondes d'Alfvén en œuvre dans le milieu interstellaire (MIS) biphasique. Je montre d'une part que les interférences des ondes internes aux nuages du MIS, négligées dans les études précédentes, renforcent l'efficacité d'injection d'énergie. D'autre part, les mouvements des nuages redistribuent l'énergie à l'échelle du système entier. Ils injectent aussi de l'énergie dans les nuages. Les modes vibratoires internes excités s'opposent à la compression des nuages et prolongent la durée de vie du système. Les nuages magnétisés constituent alors un réservoir d'énergie sur plusieurs temps dynamiques. A l'aide d'un modèle de protogalaxie biphasique, je montre que la dynamique des nuages du MIS et celle d'une protogalaxie sont équivalentes. Pour résoudre le sur-refroidissement, je propose la transposition des résultats du MIS au cas protogalactique. Malgré les diverses tentatives passées, l'origine du champ magnétique en cosmologie n'a pas trouvé d'explication satisfaisante. Or, sa place au sein du MIS et son rôle dans la formation des galaxies sont manifestes. Je propose dans ma thèse un nouveau mécanisme de magnétogenèse efficace à grande échelle, opérant à la réionisation de l'Univers, et reposant sur la pression de radiation anisotrope et inhomogène fournie par les premières structures lumineuses. A l'échelle galactique, le champ magnétique que j'obtiens est huit ordres de grandeur plus intense que dans les modèles habituels. De plus

    L’évolution de la technique opératoire fait de l'urétéroscopie souple –Laser (URSS-L) une méthode efficace et sure dans le traitement des calculs du haut appareil urinaire (HAU). Elle apparait comme une option salvatrice après échec des autres options thérapeutiques. Son coût limite son accessibilité et restreint ses indications dans certains contextes socio-économiques. Nous rapportons l'expérience du service sur les indications, les résultats et les complications de l'URSS-L dans le traitement des calculs du HAU. C'est une étude rétrospective sur 4ans concernant 130 patients ayant des calculs du HAU. Un scanner permettait de déterminer les caractéristiques des calculs avant l'intervention et de faire un contrôle après afin de juger de l'efficacité du traitement. Une analyse statistique évaluait l'influence des différents paramètres des calculs sur l'efficacité de l'intervention. Un suivi était réalisé afin de détecter les complications. L’âge moyen des patients était de 52 ± 17ans. 166 interventions étaient faites en 3 séries. Les indications étaient de première intention dans 50.32% suivi des échecs de LEC. La durée moyenne de l'intervention était de 73min ± 25min pour une taille moyenne des calculs de 13.78mm ± 5mm. Le taux de succès global était de 78.91% (78.71%; 80%; 100%) respectivement après la 1ère, la 2ème et la 3ème série. Aucun paramètre n'influençait significativement le taux de succès. 14.45% de complications était enregistré. L'URSS-L est une méthode aussi efficace que sure dans le traitement des calculs du HAU nous motivant malgré son coût, à élargir ses indications en première intention lorsque les calculs répondent aux critères de choix.

    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

    Mother-son mating (oedipal mating) is practically non-existent in social Hymenoptera, as queens typically avoid inbreeding, mate only early in life and do not mate again after having begun to lay eggs. In the ant genus Cardiocondyla mating occurs among sib in the natal nests. Sex ratios are extremely female-biased and young queens face the risk of remaining without mating partners. Here, we show that virgin queens of Cardiocondyla argyrotricha produce sons from their own unfertilized eggs and later mate with them to produce female offspring from fertilized eggs. Oedipal mating may allow C. argyrotricha queens to found new colonies when no mating partners are available and thus maintains their unusual life history combining monogyny, mating in the nest, and low male production. Our result indicates that a trait that sporadically occurs in solitary haplodiploid animals may evolve also in social Hymenoptera under appropriate ecological and social conditions.

    A qualitative phenomenological study of parents of addicted male adolescents who were residents of a Jewish therapeutic community (TC) describes and interprets the parents' perceptions of the recovery process. Deep, semistructured interviews with 14 parents provided the data. The parents' perceptions were clustered into three main themes of meaning: (a) the process of change, (b) the experiences of family members in the course of the son's recovery process, and (c) the parents' perception of the treatment at Retorno. According to the parents, the admission of their sons into the TC brought notable relief to the family life, which enabled the whole family to begin a recovery process. The findings support the positive criminology perspective that emphasizes the disintegration-integration vector as significant in the recovery process. Recommendations for intervention planning are provided.

    With increasing availability of interventions for children with autism, it is important that these are backed by rigorous evaluation data that have high levels of ecological validity. To achieve this, a key prerequisite for any evaluation is to gather data on typical consumers and typical implementation patterns of the intervention. This study collected such data longitudinally in relation to the Son-Rise Program, a home-based parent-run intervention for autism. Questionnaires and interview data on family demographics, implementation patterns, and perceived treatment fidelity were gathered three times over the course of a year from families who had attended a Son-Rise initial training course. Although it proved possible to produce a profile of intervention use, findings indicated that the programme is not always implemented as it is typically described in the literature. The study also highlighted methodological challenges likely to be encountered in any future evaluation of this and similar interventions for autism.

    2005-02-01

    Parenting responsiveness and over-reactivity were assessed among 25 mothers of 7-9-year-old sons with Attention-Deficit/Hyperactivity Disorder (ADHD) and oppositional behavior (Oppositional Defiant, OD), 24 mothers of sons with ADHD only, and 38 mothers of nonproblem sons. Responsiveness was observed during mother-son play and clean-up interactions and over-reactivity was assessed using self-reports of parenting in discipline situations. Mothers of sons with ADHD/OD were less responsive and more over-reactive than mothers of nonproblem sons, and mothers of sons with ADHD only did not differ from the other groups. Mothers of sons with ADHD/OD reported more hostility than mothers of nonproblem sons, and controlling for maternal hostility eliminated the significant group differences in responsiveness during clean-up and in over-reactivity. Controlling for the child's ADHD subtype did not alter the pattern of results. The implications for addressing responsiveness and over-reactivity as components of parent-mediated behavioral treatments for ADHD are considered.

    In 1987, 4 per cent of girls were adopted within China. Why? Unlike infanticide, abandonment rids parents of daughters while preserving the supply of potential brides. In fact, an erstwhile tradition common in Fujian and Jiangxi provinces had parents of sons adopting an infant girl to serve as a future daughter-in-law and household help. Analysing a nationally representative 1992 survey of children, we found that: (1) girl adoptions were concentrated in the above-mentioned provinces; (2) girls were predominantly adopted by families with sons; (3) adopted girls faced substantial disadvantage as measured by school attendance at ages 8-13. In the 1990s, as the sex ratio at birth climbed, were girls aborted rather than abandoned? Observing that in the 2000 census too many girls appear in families with older sons, we estimated that at least 1/25 girls were abandoned in the 1990s, a proportion that in Fujian and Jiangxi may have peaked at 1/10 in 1994.

  16. The fitness of dispersing spotted hyaena sons is influenced by maternal social status

    Life history theory predicts that mothers should provide their offspring with a privileged upbringing if this enhances their offspring's and their own fitness. In many mammals, high-ranking mothers provide their offspring with a privileged upbringing. Whether dispersing sons gain fitness benefits during adulthood from such privileges (a 'silver spoon' effect) has rarely been examined. In this paper, we show that in the complex, female-dominated society of spotted hyaenas, high-born sons grew at higher rates, were more likely to disperse to clans offering the best fitness prospects, started reproducing earlier and had a higher reproductive value than did lower-born sons. This illustrates the evolutionary importance of maternal effects even in societies in which male size or fighting ability does not influence fitness. By demonstrating for the first time in a non-human mammal that maternal status influences immigration patterns, the study also advances our understanding of two key ecological and evolutionary processes, dispersal and habitat selection.

    2013-01-01

    We use a nationally representative survey of Indian households (NFHS-3) to conduct the first study that analyzes whether son preference is associated with girls bearing a larger burden of housework than boys. Housework is a non-negligible part of child labor in which around 60 % of children in our sample are engaged. The preference for male offspring is measured by a mother’s ideal proportion of sons among her offspring. We show that when the ideal proportion increases from 0 to 1, the gap in the time spent on weekly housework for an average girl compared to that of a boy increases by 2.5 h. We conduct several robustness analyses. First, we estimate the main model separately by caste, religion, and family size. Second, we use a two-stage model to look at participation into housework (as well as other types of work) in addition to hours. Third, we use mother’s fertility intentions as an alternative measure of son preference.

    Gay men's relationships with their mothers are likely to be more positive than their relationships with their fathers, and fathers are less likely to be told, less likely to be told first, and more likely to react negatively to disclosure than mothers. Drawing on an interpretivist approach, an individual in-depth interview strategy was adopted in the study as a means of gathering data from six Afrikaans-speaking White fathers, between the ages of 53 and 61 years (median: 55.5 years), residing in Gauteng, South Africa. Interviews were audio-recorded and transcribed for later coding and analysis. Through thematic network analysis, eight organizing themes emerged and were explored. For the purpose of this article only three organizing themes are discussed, namely "subliminal awareness prior to coming out," "epistemic rupture of internal systems of ideas/beliefs," and "acceptance as a complex and ongoing dialectical and reconciliatory process." The themes support the view that most parents are neither totally rejecting nor fully accepting of their gay sons. Although the fathers may have attained a level of "loving denial" in the relationships with their gay sons, most continue to struggle with the meaning and expression of same-sex sexuality. Despite these challenges, it is recognized that the fathers are adapting to changing circumstances and are trying to find ways to tolerate, accommodate, and in some ways accept their gay sons.

    In some fibroblasts, casein kinase 1α (CK1α) is localized to nuclear speckles, which are sub-nuclear compartments supplying splicing factors, whereas it is recruited on keratin filaments in colorectal cancer cells such as DLD1 cells. In order to obtain a deeper understanding of why CK1α is localized to these different subcellular sites, we herein elucidated the mechanisms underlying its localization to nuclear speckles. CK1α and FAM83H were localized to nuclear speckles in RKO and WiDr colorectal cancer cells, which do not express simple epithelial keratins, and in DLD1 cells transfected with siRNAs for type I keratins. The localization of FAM83H to nuclear speckles was also detected in colorectal cancer cells with a poorly organized keratin cytoskeleton in colorectal cancer tissues. Using an interactome analysis of FAM83H, we identified SON, a protein present in nuclear speckles, as a scaffold protein to which FAM83H recruits CK1α. This result was supported by the knockdown of FAM83H or SON delocalizing CK1α from nuclear speckles. We also found that CK1δ and ε are localized to nuclear speckles in a FAM83H-dependent manner. These results suggest that CK1 is recruited to nuclear speckles by FAM83H and SON in the absence of an intact keratin cytoskeleton. PMID:27681590

    Parents' antisocial behavior is associated with developmental risks for their offspring, but its effects on their children's cognitive ability are unknown. We used linked Swedish register data for a large sample of adolescent men (N = 1,177,173) and their parents to estimate associations between fathers' criminal-conviction status and sons' cognitive ability assessed at compulsory military conscription. Mechanisms behind the association were tested in children-of-siblings models across three types of sibling fathers with increasing genetic relatedness (half-siblings, full siblings, and monozygotic twins) and in quantitative genetic models. Sons whose fathers had a criminal conviction had lower cognitive ability than sons whose fathers had no conviction (any crime: Cohen's d = -0.28; violent crime: Cohen's d = -0.49). As models adjusted for more genetic factors, the association was gradually reduced and eventually eliminated. Nuclear-family environmental factors did not contribute to the association. Our results suggest that the association between men's antisocial behavior and their children's cognitive ability is not causal but is due mostly to underlying genetic factors.

    Recent exploration of the south east Nam Con Son Basin, offshore Vietnam, by BP in alliance with Statoil has involved acquisition of new seismic and well data. These new data have allowed re-evaluation of the tectono-stratigraphic development and petroleum geology, and have provided additional constraints on the regional tectonic evolution. The offshore Vietnamese basins have evolved in response to the complex relative motions of Indochina, Peninsular Malaysia, Borneo and the South China Sea during the Cenozoic. On the regional scale these motions have been accommodated by strike-slip fault development, rifting and contraction. In the Nam Con Son Basin these motions have interacted in different ways from the Palaeogene to recent. Two rifting episodes are recognized; a Palaeogene phase dominated by E-W trending extensional faults, and a Miocene phase dominated by N-S to NE-SW trending faults. The structural evolution is complicated by a pulse of mild contraction during the Middle Miocene. The sedimentary fill of the basin evolves from continental fluvio-lacustrine in the Palaeogene through to fully marine following the second phase of rifting in the Miocene. This pulsed structural and stratigraphic evolution has resulted in basinwide deposition of source, reservoir and seal facies, and produced a variety of potential trapping styles. This paper describes the hydrocarbon habitat of the south east Nam Con Son Basin within the context of the regional tectono-stratigraphic model.

    Meule, Samuel

    Roberts Bank couvre le delta intertidal entre le bras principal du fleuve Fraser et la pointe du Cap Roberts en Colombie Britannique, Canada. Sous la pression du developpement urbain et la modification du regime sedimentaire, cette plage de sable fin est soumise a une erosion significative. L'identification des forces hydrodynamiques, leur importance et leur interaction permettent de determiner les zones de transport, et donc la stabilite de Roberts Bank. Deux periodes de mesures associees a des phases de modelisation de la houle et des courants ont ete effectuees lors de ce travail. La premiere periode de mesure, entre le 29 juin et le 8 juillet 2001, a permis l'identification de processus hydrodynamiques et sedimentaires associes aux forts courants de maree presents le long de Roberts Bank. La seconde phase de mesure, entre le 1er mars et le 26 mars 2002, a permis d'etudier les processus de remise en suspension associes a la houle. Des phases de modelisation ont ete menees a partir des connaissances acquises sur le terrain, afin d'affiner la comprehension des processus sedimentaires et notamment les interactions houle - courant - sediment. Les mecanismes, mis en evidence dans cette etude, participent au faconnage de Roberts Bank, contribuent a son erosion et a la mise en place de nouvelles structures sedimentaires. Les courants de flot de maree vont initier la creation de nuages de resuspension de sediment depuis le fond. En eau peu profonde, la composante " onshore" du courant de maree induit un transport a la cote, tandis qu'en eau plus profonde une faible composante " offshore" du courant peut favoriser un transport au large le long de la pente. Les chenaux, les dunes subaquatiques et les surfaces d'erosion affleurantes fournissent une rugosite de fond suffisante a la generation de turbulence et donc de nuages de sediment en suspension. Lors de la maree de jusant, les sediments resuspendus en eau peu profonde, sont transportes vers le large a partir d

    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.

    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.

    2013-01-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting. PMID:18821352

Objectif: Déterminer la capacité à diagnostiquer le syndrome métabolique en routine, sa prévalence chez les diabétiques, leurs connaissances et pratiques vis-à-vis du risque cardio-métabolique. Méthodes Il s'est agi d'une étude transversale auprès de 388 diabétiques au CHU de Bobo-Dioulasso. Les critères de la fédération internationale du diabète (2009) ont été utilisés. Résultats l’âge moyen était de 53,5±13,5 ans, le sex ratio de 0,7. L'obésité abdominale était présente dans 61,9% des cas; L'HTA l’était dans 56,4% des cas. La prescription du bilan lipidique a été documentée dans 55,4% des cas pour le HDL et 56,2% pour les triglycérides pour un taux de réalisation de 49,3% et 62,9%. Le taux de dépistage des critères lipidiques était de 26,8%. Un taux de HDL bas a été noté dans 46 cas (43,4%) et une hypertriglycéridémie dans 24 cas (17,6%). In fine, la prévalence du syndrome métabolique était de 48,9% (n = 190). Seuls 27,4% savaient que d'autres facteurs de risque cardiovasculaire pouvaient être associés au diabète et seulement 6,7% pratiquaient une activité physique régulière. Conclusion Malgré la faible contribution du laboratoire, le syndrome métabolique est fréquent parmi nos diabétiques. Les patients sont peu sensibilisés sur le risque vasculaire et la pratique d'une activité physique régulière reste faible. Un programme d’éducation adaptée contribuerait à un meilleur dépistage et à une prise en charge optimale des cas. PMID:25932077

    Based on the recommendations of the sub-workgroup on trauma and dissociative disorders, the American Psychiatric Association (APA) removed the "bereavement exclusion" from the criteria for major depression in DSM-5. In addition, proposed DSM-5 research criteria for persistent complex bereavement disorder (PCBD) were included in the new manual in a section for conditions and criteria needing further research. We describe a case that warranted such a diagnosis. The patient was a 52- year-old woman who was admitted to the inpatient unit of our clinic on the birthday of her son who had died 18 months earlier. She was diagnosed with a manic episode with psychotic symptoms according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and was treated accordingly. Three months after discharge, she made a suicide attempt and was admitted and re-assessed. During this admission, she completed the Inventory of Complicated Grief (ICG), the Mood-Spectrum Rating Scale (MOODS-SR), and the Trauma and Loss Spectrum questionnaire (TALS-SR). She endorsed symptoms of intense yearning for her son, feelings of shock and disbelief, anger and bitterness related to his death, estrangement from others, auditory, tactile and visual hallucinations of the deceased, and intense emotional reactivity to memories of her son. These symptoms were sufficiently prolonged and severe to meet criteria for complicated grief. While complicated grief appeared to be the primary diagnosis for this patient, when she was diagnosed using only DSMIV-TR criteria, her treatment failed to address herprimary problem. This case draws attention to the occurrence of manic-like symptoms as well as depression-like manifestations following bereavement and highlights the importance of including the syndrome of complicated grief in the diagnostic nomenclature.

    Once faced with structure reactivity relationships in the context of nucleophilic substitution at sp 3 carbon, introductory organic chemistry students must compare and contrast the various attributes and ramifications of S N 2 versus S N 1 reaction pathways. The dramatic (even melodramatic) way in which some students ask such comparative questions inspired a parody of Hamlet's famous to be or not to be soliloquy. Herein, Hamlet (the son of an organic chemist of Denmark) is the surrogate of any and every student as he uses a thoroughly Shakespearian approach to sorting out some of the key distinguishing features of S N 2 versus S N 1 reactions.

    Here we present, for the first time, the results from pilot deployments of the Son-O-Mermaid project, an autonomously drifting, oceangoing data-collection platform that can be cheaply deployed without the need for a costly research vessel, and that records and transmits hydroacoustic signals (with a target of those generated by teleseismic earthquakes) in near real-time. Both deployments employ three identical hydrophones spaced about 70 cm apart at the end of a 700 m long cable attached to a surface buoy that houses electronics, communications, and a GPS location package. The maiden voyage occurred October 8, 2012, in Exuma Bay, Bahamas and returned 25 hours of acoustic data. A second deployment is to take place in September 2014, with near-immediate data relay via Iridium modem. The experimental setup is different from the MERMAID instrument, which sinks to a midcolumn depth and surfaces to transmit waveforms when an event detection algorithm is triggered. MERMAIDs have recorded hundreds of seismic traces from 18 active floats in the Indian and Mediterranean Oceans with a signal-to-noise ratio suitable for global tomography. As with earthquake early-warning studies, both Son-O-Mermaid and MERMAID benefit from rapid and accurate event detection, discrimination, and measurement technology. With this triple purpose in mind we continue to improve methods (in the time-domain, via spectrogram analysis and using wavelets) that we illustrate on the latest and some of the older data, as well. While hydroacoustic data have numerous other applications beyond seismology (whale calls, ice calving, weather patterns, and so on) the Son-O-Mermaid and MERMAID instruments may potentially revolutionize seismic data collection in the oceans. Moreover, in the near future they will be fitted with more or different instruments, becoming multipurpose and multidisciplinary platforms for all types of scientific research in and of the oceans. In seismology we envision a future when the

    The 16th century French anatomist Guillaume Rondelet will be remembered as a great naturalist and a founder of ichthyology. Little known to most is that Rondelet was a proficient anatomist and contemporary to Vesalius and in fact, both studied anatomy under Johannes Guinter. Even less known is that he established the first dissecting theatre at Montpellier and it was here that he would dissect his infant son in an attempt to identify the cause of death. In this article, we review the life and contributions to anatomy of Rondelet.

    Le tabagisme est une des principales causes de morbidité et de mortalité évitable. Le but de ce travail est d’évaluer les connaissances du fumeur vis-à-vis les risques du tabac et son motivation pour cesser de fumer. Nous avons réalisé une enquête transversale chez les malades tabagiques hospitalisés au service en répondant à un questionnaire précisant leur niveau socio-économique et culturel, l'histoire du tabagisme, les méfaits connus du tabac, la dépendance pharmacologique à la nicotine et leur motivation pour cesser de fumer. Il s'agit de 120 patients, l’âge moyen était de 45 ans±15. Les principaux motifs d'hospitalisation étaient: pathologie tumorale (54%), pathologie infectieuse (35%) BPCO (9%). 85% des patients étaient scolarisés jusqu'au cycle secondaire. Pour l'ensemble des patients, l’âge moyen de la première cigarette était précoce (avant de 20 ans) et la dépendance pharmacologique à la nicotine était légère (82% avaient un score de Fagerström < 8). Plus d'un tiers des patients (38%) avaient au moins fait une tentative d'arrêt. La connaissance des effets néfastes du tabac était variable: les pathologies cancéreuses (88%), les maladies cardiovasculaires (65%) et la BPCO (31%). La majorité des patients (78%) avaient cessé de fumer depuis l'hospitalisation. Notre enquête met en évidence l'intérêt de la médiatisation dans l'information de la population sur les risques du tabac. Les pneumologues, qui prennent en charge la grande majorité de ces patients, doivent donc s'impliquer activement dans ce domaine. PMID:25745534

Méthodes Il s'agit d'une étude rétrospective descriptive et analytique menée sur 8 ans (Janvier 2005-Décembre 2012) dans le service d'hépato-gastroentérologie (HGE) du CHU Campus de Lomé. Etaient inclus les dossiers des patients hospitalisés pour CO confirmé histologiquement. Résultats Sur 8 ans, 24 patients remplissant nos critères d'inclusion ont été retenus soit 3cas de CO par an et 0,55% des hospitalisations. L’âge moyen des patients était de 57,08 ans (extrêmes: 32 et 82 ans). La dysphagie et l’épigastralgie étaient les motifs d'hospitalisation les plus rencontrés. L'alcool (n=15), le tabac (n=13) étaient les facteurs de risque les plus présents. A la fibroscopie, les lésions étaient ulcéro-bourgeonnantes et hémorragiques (n=12), ulcéro-bourgeonnantes (n=5); ces lésions siégeaient au niveau du 1/3 inférieur (n= 11), à l'union 1/3 supérieur 1/3moyen de l’œsophage (n= 13) et aucun au niveau du 1/3 supérieur. Seize lésions étaient des carcinomes épidermoïdes et 3 des adénocarcinomes. L’évolution dans le service a été fatale dans 2cas; 16 patients avaient été transférés en chirurgie pour des soins palliatifs et 5 patients (20,8%) étaient perdus de vue. Conclusion Le CO semble en augmentation au Togo. L'alcool et le tabac sont les facteurs de risque et le pronostic sévère dans notre série est lié au retard diagnostic. Son dépistage précoce passe par une consultation rapide devant toute dysphagie chez un sujet de 50 ans et plus. PMID:25883742

    2000-01-01

    This study explored the possibility that changes in feelings of trust for mother are associated with gay males' decisions to disclose (or withhold) their sexual orientation in their mother-son relationships. Fifty gay and bisexual males completed a questionnaire about their coming out experiences in the context of their relationships with their mothers. As part of this questionnaire, they completed a retrospective graphical trust history task that involved plotting the degree of trust they felt for their mothers over time and across important events (such as disclosure). Results are discussed in terms of gay men's expectations about their mothers' responses to disclosure, the evidence for stability versus change in their memories regarding the nature of their feelings of maternal trust over time, the complexity of the trust histories participants drew, similarity between disclosers and non-disclosers in the shape of their trust curves, and the types of events and experiences that constituted the timeline or "plot" in the stories participants told about their mother-son relationships. This study offers the first empirical evidence to support speculations linking disclosure of sexual orientation to the climate of trust that exists in the relationship between discloser and target (e.g., Holtzen, Kenny & Mahalik, 1995).

    The author uses the material of Korean myths and folktale and from a patient to understand the way in which the Oedipus complex is negotiated and resolved in Korean society. In Korean myth and folktale a benign and supportive pre-oedipal father-son relationship is more appreciated and encouraged than the competition and rivalry in the oedipal father-son relationship. Consequently, in Korean myth the boy can develop balanced masculinity through the father's encouragement and protection and set out on his own journey to be a man as strong as his father. Oedipus, in contrast, was abandoned by the parent, which led him to act out his unconscious desire to kill the father, ending with total destruction. The difficulties of applying western-based psychoanalytic theory to Korean culture are discussed. Although we are influenced by historical, social and cultural patterns of external reality, we are more influenced by our unconscious than we are aware of, which enables us to share current psychoanalytic knowledge to understand Korean myths and patients without much deviation.

    In Thailand, Mae Hong Son Province is highly endemic for malaria. Knowing this, the local Health Department has introduced a program to educate local residents about the risk factors, in particular the dangers and symptoms of malaria. This study was conducted to evaluate these efforts, by determining the number of malaria infections in a segment of the population, and also by testing for enterobiasis among a group of its children. Two villages in Mae Hong Son Province were chosen for this purpose with a combined population of about 300. Of these, 195 were screened for malaria. Two subjects were diagnosed positive for malaria by microscopy. One of these two villages was chosen to screen for Enterobius vermicularis infection in children as well. Out of 69 stool samples, five (7%) showed infection with E. vermicularis: three with a low number of eggs (1-50), and two with a high number of eggs (>100). Compared with infection rates in similar studies, the results of this study indicate that the Health Department's efforts are meeting with relative success. The low prevalence of infection indicates that the villagers are using the information they have received to help combat infection.

    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.

  16. Bartonella henselae bacteremia in a mother and son potentially associated with tick exposure

    PubMed Central

    2013-01-01

    Background Bartonella henselae is a zoonotic, alpha Proteobacterium, historically associated with cat scratch disease (CSD), but more recently associated with persistent bacteremia, fever of unknown origin, arthritic and neurological disorders, and bacillary angiomatosis, and peliosis hepatis in immunocompromised patients. A family from the Netherlands contacted our laboratory requesting to be included in a research study (NCSU-IRB#1960), designed to characterize Bartonella spp. bacteremia in people with extensive arthropod or animal exposure. All four family members had been exposed to tick bites in Zeeland, southwestern Netherlands. The mother and son were exhibiting symptoms including fatigue, headaches, memory loss, disorientation, peripheral neuropathic pain, striae (son only), and loss of coordination, whereas the father and daughter were healthy. Methods Each family member was tested for serological evidence of Bartonella exposure using B. vinsonii subsp. berkhoffii genotypes I-III, B. henselae and B. koehlerae indirect fluorescent antibody assays and for bacteremia using the BAPGM enrichment blood culture platform. Results The mother was seroreactive to multiple Bartonella spp. antigens and bacteremia was confirmed by PCR amplification of B. henselae DNA from blood, and from a BAPGM blood agar plate subculture isolate. The son was not seroreactive to any Bartonella sp. antigen, but B. henselae DNA was amplified from several blood and serum samples, from BAPGM enrichment blood culture, and from a cutaneous striae biopsy. The father and daughter were seronegative to all Bartonella spp. antigens, and negative for Bartonella DNA amplification. Conclusions Historically, persistent B. henselae bacteremia was not thought to occur in immunocompetent humans. To our knowledge, this study provides preliminary evidence supporting the possibility of persistent B. henselae bacteremia in immunocompetent persons from Europe. Cat or flea contact was considered an unlikely

    In this study, 363 Korean father-son haplotype transfers in 351 families were analyzed using an in-house multiplex PCR system for 14 Y-STRs (DYS385a/b, DYF387S1, DYS391, DYS449, DYS460, DYS481, DYS518, DYS533, DYS549, DYS570, DYS576, DYS627 and DYS643), that included 11 loci newly added to the PowerPlex Y23 system or the Yfiler Plus system. The Y-STRs showed gene diversity values ranging from 0.2499 to 0.9612; the multicopy Y-STR loci DYS385 and DYF387S1 had high gene diversity of 0.9612 and 0.9457, respectively. In addition, DYF387S1, which has two copies, showed three alleles in seven individuals, and micro-variant alleles were observed in 14 individuals at four loci (DYS448, DYS518, DYS570 and DYS627). Among 351 haplotypes for the 11 newly added Y-STRs, 350 different haplotypes were observed, with an overall haplotype diversity of 0.9999 and discrimination capacity of 99.72%. In 363 haplotype transfers from 351 pedigrees, 29 single-step mutations were observed at 11 Y-STRs. Locus-specific mutation rate estimates varied from 0.0 to 1.93×10(-2), with an average estimated mutation rate of 6.66×10(-3). Two father-son pairs had mutations at two different loci in 11 Y-STRs. The number of pairs with mutations at multiple loci increased to five when the mutation event was investigated for haplotype transfer at 28 Y-STRs including 17 Yfiler loci and 11 Y-STRs examined in this study: four father-son pairs had mutations at two loci, and one pair had mutations at three loci. Overall, mutations were frequently observed at DYS449, DYS576 and DYS627 loci, which are known to be rapidly mutating Y-STRs. Mutation rate estimates at most loci were not significantly different from rates in other populations, but estimates for DYF387S1, DYS518 and DYS570 were considerably lower in the Korean population than in other populations.

  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

    We describe in this paper the everyday support mothers give to their adult sons or daughters suffering from psychotic disorders. We also describe the support these women receive from their social network regarding specific needs related to their children's disorders. Ninety-nine women, representing all socioeconomic groups, were interviewed. They were recruited through hospitals and self-help groups. The results of this study highlight the fact that participants give a substantial amount of support to their children, that they have considerable concern for their children's well-being, and that members of their family are their main source of emotional and practical support, and of advice. Mental health professionals give primarily informational support to respondents, in part through community-based agencies. The respondents who belong to self-help groups have significantly more needs related to their children's disorders and have more concern for their children's well-being than do the other respondents.

  20. Bad Mothers and Monstrous Sons: Autistic Adults, Lifelong Dependency, and Sensationalized Narratives of Care.

    PubMed

    Allen, Holly

    2017-03-01

    Sensationalized representations of autistic families in film and other media frequently feature violent encounters between mothers and sons. This essay analyzes two media stories and three films that suggest how limited-and therefore misleading-popular representations of the autism family are. Except for one of the films, these representations blame the problem of adult autistic dependency on either monstrous autism or bad mothering. Doing so elides collective social responsibility for autism care and denies the reality that autistic adults continue to have complex dependency needs that families cannot always meet. Narratives that sensationalize youth and adults with autism or scapegoat their maternal caregivers also diminish opportunities for social inclusion and for autistic people to live fully and dependently.

    This study investigates parenting practices and the reported sexual and delinquent behaviors among Thai adolescents, by focusing on the difference between sons and daughters. Data were derived from 420 families whose adolescents aged 13–14 were randomly selected from seven districts in Bangkok using the probability proportional to size (PPS) method. Interviews were conducted with one parent and one adolescent. Female adolescents reported higher levels of parental monitoring, parental rules, communication about sex and parental disapproval of sex, as compared to males. There were no gender differences in the reported sexual and delinquent behaviors among the adolescents. For males, high levels of parental monitoring, greater perception of parent disapproval of sex, and being raised by authoritative parents were associated with less delinquent behaviors. Among females, parental monitoring and parental closeness served as protective factors against sexual and delinquent behaviors. These findings should be useful for developing a body of knowledge and understanding on adolescent rearing among Thai parents. PMID:20420103

    The unambiguous detection of individual solar internal g modes continues to elude us. With the aid of new additions to calibration procedures, as well as updated methods to combine multi-site time series more effectively, the noise and signal detection threshold levels in the low-frequency domain (where the g modes are expected to be found) have been greatly improved. In the BiSON 23-year dataset these levels now rival those of GOLF, and with much greater frequency resolution available, due to the long time series, there is an opportunity to place more constraints on the upper limits of individual g mode amplitudes. Here we detail recent work dedicated to the challenges of observing low-frequency oscillations using a ground-based network, including the role of the window function as well as the effect of calibration on the low frequency domain.

    2008-08-01

    Periventricular nodular heterotopia is a common malformation of cortical development in which the migration of developing neurons destined for the cerebral cortex is abbreviated. Bilateral periventricular nodular heterotopia is most commonly an X-linked disorder that involves mutations in the filamin A (FLNA) gene, but an autosomal recessive form and sporadic forms have been identified. To our knowledge, autosomal dominant transmission of isolated periventricular nodular heterotopia has not been reported. Periventricular nodular heterotopia has a heterogeneous phenotype, associated commonly with seizure disorder, and more recently with reading deficits and visual-spatial deficits in some patients. We present a father and son with bilateral periventricular nodular heterotopia and similar visual-spatial learning deficits, consistent with nonverbal learning disability.

    2003-02-01

    This study examined trajectories of disruptive behavior problems from preschool to early adolescence in 302 boys from a community-recruited sample of high-risk families. Growth modeling showed that paternal alcoholism was associated with elevated levels of sons' disruptive behavior problems. Family conflict predicted more disruptive behaviors at school entry and a slower rate of decline in such problems. Parent antisocial personality disorder (ASPD) exacerbated the effects of high preschool levels of sons' undercontrol on level of disruptive behaviors at school entry; this effect became progressively stronger across time. Low levels of undercontrol protected sons of ASPD parents from experiencing heightened levels of disruptive behaviors both at school entry and increasingly as sons grew older. Implications for subsequent maladjustment are discussed.

  6. Collaboration between therapists in the simultaneous treatments of a father and son with disorders of masculine identity formation.

    PubMed

    Stein, G S; Chittenden, C L

    A chronically depressed, middle-aged man with numerous intermittent psychotherapies since adolescence, sought treatment for difficulties provoked by his corrupt, former boss. Because of inadequate fathering, he had been unable to consolidate his identity as a man and a father, which inhibited the development of masculine and paternal identity in his oldest son. This patient enacted and worked through massive resistance to experiencing the idealized, paternal transference so lacking in his relationship with his own father; thereby enhancing his son's development and aiding his own separation from his mother and his wife. But this upset the family equilibrium and angered the wife, as she could no longer protect and control her husband and son, thereby enacting her transference to her alcoholic father. The psychotherapists' close collaboration helped elucidate this family's complex, interwoven psychopathology. Simultaneous treatment with collaboration thus contributed to the separation and individuation of father, mother, and son and facilitated later resolution of their oedipal conflicts.

    2005-12-16

    The last 50 years in the history of life sciences are remarkable for a new important feature that looks as a great threat for their future. A profound specialization dominating in quickly developing fields of science causes a crisis of the scientific method. The essence of the method is a unity of two elements, the experimental data and the theory that explains them. To us, "fathers" of science, classically, were the creators of new ideas and theories. They were the true experts of their own theories. It is only they who have the right to say: "I am the theory". In other words, they were carriers of theories, of the theoretical knowledge. The fathers provided the necessary logical integrity to their theories, since theories in biology have still to be based on strict mathematical proofs. It is not true for sons. As a result of massive specialization, modern experts operate in very confined close spaces. They formulate particular rules far from the level of theory. The main theories of science are known to them only at the textbook level. Nowadays, nobody can say: "I am the theory". With whom, then is it possible to discuss today on a broader theoretical level? How can a classical theory--for example, the membrane one--be changed or even disproved under these conditions? How can the "sons" with their narrow education catch sight of membrane theory defects? As a result, "global" theories have few critics and control. Due to specialization, we have lost the ability to work at the experimental level of biology within the correct or appropriate theoretical context. The scientific method in its classic form is now being rapidly eroded. A good case can be made for "Membrane Theory", to which we will largely refer throughout this article.

  9. Bidirectional Associations Between Externalizing Behavior Problems and Maladaptive Parenting Within Parent-Son Dyads Across Childhood.

    PubMed

    2016-10-01

    Coercive parent-child interaction models posit that an escalating cycle of negative, bidirectional interchanges influences the development of boys' externalizing problems and caregivers' maladaptive parenting over time. However, longitudinal studies examining this hypothesis have been unable to rule out the possibility that between-individual factors account for bidirectional associations between child externalizing problems and maladaptive parenting. Using a longitudinal sample of boys (N = 503) repeatedly assessed eight times across 6-month intervals in childhood (in a range between 6 and 13 years), the current study is the first to use novel within-individual change (fixed effects) models to examine whether parents tend to increase their use of maladaptive parenting strategies following an increase in their son's externalizing problems, or vice versa. These bidirectional associations were examined using multiple facets of externalizing problems (i.e., interpersonal callousness, conduct and oppositional defiant problems, hyperactivity/impulsivity) and parenting behaviors (i.e., physical punishment, involvement, parent-child communication). Analyses failed to support the notion that when boys increase their typical level of problem behaviors, their parents show an increase in their typical level of maladaptive parenting across the subsequent 6 month period, and vice versa. Instead, across 6-month intervals, within parent-son dyads, changes in maladaptive parenting and child externalizing problems waxed and waned in concert. Fixed effects models to address the topic of bidirectional relations between parent and child behavior are severely underrepresented. We recommend that other researchers who have found significant bidirectional parent-child associations using rank-order change models reexamine their data to determine whether these findings hold when examining changes within parent-child dyads.

    Dr. Suh Yang Park was born in 1885 as a son of a butcher, which was the lowest class at that time in Korea. However, contact with western missionaries, including Dr. 0. R. Avison, provided him with an understanding of western civilization. After entering Chejungwon Medical School in 1900, Dr. Park learned basic sciences, basic medical sciences like anatomy and physiology, and other Western medical specialties such as internal medicine and surgery. He graduated from medical school in 1908 and received Government Certificate from Home Office, the first in Korea in this field, which granted the right to practice medicine. His certificate number was 4th overall. As both a doctor and a talented musician, Dr. Park actively participated in the social enlightenment movement. He was quite progressive in his time, having surpassed the social limitations as a son of a butcher, as well as actively propagating his knowledge of Western civilization onto others. After graduation, he had served as a professor at the school he graduated from, until he went into exile in Manchuria in 1917 due to the annexation of Korea by Japan in 1910. There, he opened a hospital and provided medical treatment for Koreans. He also established a school for young Koreans, inspiring them with a sense of nationalism. Also, Dr. Park was an active member of various Independence Movement Organizations in Manchuria. Then in 1932, at the time when Japan took control of Manchuria, his school was closed down. As a result, Dr. Park couldn't help but stop his anti-Japanese activities. In 1936, he returned to his homeland and passed away in 1940, just five years before the liberation of Korea from Japanese occupation.

    Studies of normotensive offspring of hypertensive parents offer the potential to identify inherited abnormalities that contribute to essential hypertension. We compared renal and systemic hemodynamic responses to saline infusion between normotensive sons of two hypertensive parents (SOHT) and sons of two normotensive parents (SONT) selected from the general population of Rochester, Minn. Hemodynamic measurements were performed after a week of low sodium intake (10 meq/day) and were repeated after a week of high sodium intake (200 meq/day). Despite being in the normotensive range, blood pressures in SOHT were higher than those in SONT during low sodium (124 +/- 3/85 +/- 3 versus 118 +/- 2/71 +/- 2 mm Hg, p less than 0.01) and high sodium (122 +/- 3/80 +/- 3 versus 112 +/- 2/70 +/- 2 mm Hg, p less than 0.05) conditions. Higher pressures in SOHT were associated with elevated systemic and renal vascular resistance. After a high sodium diet, renal vascular resistance in SOHT rose further during acute saline infusion, whereas systemic vascular resistance did not change. After a low sodium diet, this renal vasoconstrictor response to saline infusion in SOHT was not present, and renal vascular resistance fell to levels not different from SONT. Plasma renin activity, aldosterone, and atrial natriuretic peptide did not differ between SONT and SOHT. Circulating levels of norepinephrine were higher in SOHT. These data demonstrate a renal vasoconstrictor response to saline infusion in normotensive SOHT, which depends on prior sodium intake. This alteration in renal hemodynamics may represent an inherited abnormality related to the development of hypertension.

    Background Animal studies have demonstrated that timing of pubertal onset can be altered by prenatal exposure to dioxins or polychlorinated biphenyls (PCBs), but studies of human populations have been quite limited. Methods We assessed the association between maternal serum concentrations of dioxins and PCBs and the sons’ age of pubertal onset in a prospective cohort of 489 mother–son pairs from Chapaevsk, Russia, a town contaminated with these chemicals during past industrial activity. The boys were recruited at ages 8 to 9 years, and 4 years of annual follow-up data were included in the analysis. Serum samples were collected at enrollment from both mothers and sons for measurement of dioxin and PCB concentrations using high-resolution mass spectrometry. The sons’ pubertal onset—defined as pubertal stage 2 or higher for genitalia (G) or pubic hair (P), or testicular volume >3 mL—was assessed annually by the same physician. Results In multivariate Cox models, elevated maternal serum PCBs were associated with earlier pubertal onset defined by stage G2 or higher (4th quartile hazard ratio = 1.7 [95% confidence interval = 1.1– 2.5]), but not for stage P2 or higher or for testicular volume >3 mL. Maternal serum concentrations of dioxin toxic equivalents were not consistently associated with the sons’ pubertal onset, although a dose-related delay in pubertal onset (only for G2 or higher) was seen among boys who breast-fed for 6 months or more. Conclusions Maternal PCB serum concentrations measured 8 or 9 years after sons’ births—which may reflect sons’ prenatal and early-life exposures—were associated with acceleration in some, but not all, measures of pubertal onset.

    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

    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.

    Summary Les Auteurs décrivent le cas d’un patient âgé de 45 ans atteint de brûlures thermiques par flammes suite à la déflagration d’une bonbonne de gaz. Les lésions initiales intéressaient les quatre membres (en particulier, le genou) et le tronc. La prise en charge initiale a consisté en une excision-greffe précoce des membres. L’évolution a été marquée par la survenue de cicatrices hypertrophiques au niveau des zones non greffées et à la bordure de la greffe ainsi que la survenue de brides rétractiles. Devant l’handicap fonctionnel engendré par la bride à cause de la limitation importante de l’extension, le patient a été admis pour cure chirurgicale. Grâce à la technique en rail décrite, le patient a pu récupérer une fonction normale du genou. Les suites ont été simples avec une durée d’hospitalisation d’un mois. Le résultat esthétique est relativement satisfaisant. La technique en rail est un moyen parmi l’arsenal thérapeutique qui permet de traiter la bride du creux poplité. Sa simplicité, sa facilité technique et son résultat satisfaisant ainsi que ses suites simples permettent de la rendre une technique très prisée dans le traitement de ce type de bride. PMID:21991240

    Cri-du-Chat syndrome, also called the 5p-syndrome, is a rare genetic abnormality, and only few cases have been reported on its brain MRI findings. We describe the magnetic resonance imaging findings of a 1-year-old girl with Cri-du-Chat syndrome who showed brain stem hypoplasia, particularly in the pons, with normal cerebellum and diffuse hypoplasia of the cerebral hemispheres. We suggest that Cri-du-Chat syndrome chould be suspected in children with brain stem hypoplasia, particularly for those with high-pitched cries.

    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

    Introduction L'infection par le virus de l'hépatite B (VHB) est une affection grave suite à ses complications notamment la cirrhose et le carcinome hépatocellulaire (CHC). Les génotypes du VHB influent beaucoup sur son évolution et sur l'efficacité du traitement. Le but était d’évaluer les génotypes du VHB et les profils évolutifs des patients porteurs chroniques de l'AgHBs. Méthodes Étude transversale, menée au Centre hospitalo-universitaire de Kamenge et au Centre des maladies du tube digestif et du foie « CEMADIF » entre Juin 2013 et Mai 2014. Le génotypage, les dosages quantitatifs de l'AgHBe et de l'ADN virale B ont été réalisés au Laboratoire Cerba, Cergy Pontoise, France. L’évaluation de la fibrose était faite par le Fibrotest ou le FibroScan. Résultats Au total, 143 patients, 52,4% de sexe masculin, âge moyen 38,1 ans ont été inclus. Selon les marqueurs évolutifs, 112 patients (78,3%) avaient un AgHBe négatif. Quant à la charge virale, 106 patients (74,2%) avaient une virémie inférieure à 2000UI/ml et une fibrose minime inférieure à 7kpa selon le FibroScan. Parmi eux, 13 malades avaient un ADN du VHB indétectable (<20UI/ml). Les autres 37 patients (26,8%) avaient une charge virale supérieure à 2000UI/ml et parmi eux, 31 avaient un AgHBe positif (>0,8UI/ml). Il a été possible de déterminer le génotype chez 51 patients qui avaient une virémie assez élevée pour permettre techniquement ce dosage. Ces patients avaient tous un génotype A. Conclusion Le génotype A du VHB est le plus fréquent à Bujumbura. Il est associé à un portage inactif élevé. PMID:27222687

    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.

    The Kochen-Specker (KS) theorem lies at the heart of the foundations of quantum mechanics. It establishes the impossibility of explaining predictions of quantum theory by any noncontextual ontological model. Spekkens generalized the notion of KS contextuality in [Phys. Rev. A 71, 052108 (2005), 10.1103/PhysRevA.71.052108] for arbitrary experimental procedures (preparation, measurement, and transformation procedures). Interestingly, later on it was shown that preparation contextuality powers parity-oblivious multiplexing [Phys. Rev. Lett. 102, 010401 (2009), 10.1103/PhysRevLett.102.010401], a two-party information theoretic game. Thus, using resources of a given operational theory, the maximum success probability achievable in such a game suffices as a bona fide measure of preparation contextuality for the underlying theory. In this work we show that preparation contextuality in quantum theory is more restricted compared to a general operational theory known as box world. Moreover, we find that this limitation of quantum theory implies the quantitative bound on quantum nonlocality as depicted by the Cirel'son bound.

    Permo-Triassic intermediate-felsic magmatism is developed along the Truong Son fold belt, located in the eastern margin of the Indochina Block. It comprises a succession of the active continental margin associations: calc-alkaline volcano-plutonic associations (272-248 Ma), peraluminous granites (259-245 Ma), and subalkaline felsic volcano-plutonic associations (younger than 245 Ma). Detailed study of geochemical characteristics such as trace elements (LILE, REE, HFSE) and isotopes (Sr, Nd, Pb) indicates that they are homogeneous and that they are products of the Palaeotethys subduction process in relation to Indochina (IC)/North Vietnam-South China (NV-SC) amalgamation (S.L. Chung et al., Abstr., GEOSEA 98, Malaysia, 1998, pp. 17-19). The Indosinian characteristics are represented by mantle-crust interaction in magma generation, controlled by their emplacement localities in relation to the Kontum Uplift. The spatial and temporal evolution of Permo-Triassic magmatism allows reconstructing the geodynamic history of the Indosinian orogeny. It confirms that this event ended in Early to Middle Triassic (246-240 Ma, after C. Lepvrier et al., Tectonophysics 393 (2004) 87-118).

    The 3He behavior in the non active R7T7 type borosilicate glass called SON68 has been investigated using the implantation method to introduce helium in the material. Nuclear Reaction Analysis (NRA) was performed to follow the helium concentration depth profile evolution as a function of annealing time and temperature. In addition, in situ Transmission Electron Microscopy (TEM) has been implemented to study the formation of helium bubbles during both implantation and annealing processes. Numerical modeling with two different approaches is proposed and discussed to investigate the helium mobility mechanisms. Our study reveals for helium incorporation by implantation at low temperature the presence of several helium populations with disparate diffusivities. The most mobile helium fraction would be attributed to atomic diffusion. The corresponding activation energy value (0.61 eV) extracted from Arrhenius graphs is in good agreement with literature data. The results also highlight that the damages associated to helium sursaturation are the source of small helium clusters formation, with a reduced mobility instead of the atomic mobility measured by the infusion technique. Small cavities that support this assumption have been observed by TEM at low temperature.

  5. The Harmonic Convergence of Fathers Predicts the Mating Success of Sons in Aedes aegypti.

    During courtship males often communicate information about their fitness to females. The matching of harmonic components of flight tone in male-female pairs of flying mosquitoes, or harmonic convergence, was recently described. This behaviour occurs prior to mating and has been suggested to function in mate selection. We investigated the hypothesis that harmonic convergence is a component of mosquito courtship. A key prediction of this hypothesis is that harmonic convergence should provide information to potential mates about fitness benefits. We measured the effect of harmonic convergence behaviour on the direct and indirect benefits obtained by females. We found that the sons of pairs that converged at harmonic frequencies prior to mating had increased mating success and that these offspring were themselves more likely to converge prior to mating. These results suggest that males may be able to signal information about their genetic quality to females prior to mating and that this signal may be heritable. These findings are important for our understanding of mosquito behaviour and have applications in the control of mosquito-borne disease. This study also contributes to the study of male-female interactions and signal coevolution.

    Theoretical and empirical research on the evolution of clutch size has proved to be an extremely productive area of evolutionary biology. A general prediction is that individuals should produce a smaller number of offspring when resources are more limited, such as when multiple individuals compete for the same resources for their development. However, we expect that the opposite prediction arises with virgin females of haplodiploid species, which are subject to extreme local mate competition. We test the key assumption and predictions of this theory with the parasitoid wasp Melittobia australica. Our data demonstrate that there is a trade-off between the size of the first and subsequent clutches and that virgin females adjust their production of sons according to the mating status (mated or not) of cofounding females. We also found that mated females facultatively change their offspring sex ratio in response to the mating status of cofoundresses. We discuss the potential mechanisms used to recognize the mating status and the implications of our results in the context of the extremely female-biased sex ratios observed across Melittobia species..

    OBJECTIVE: To examine the experiences of men who are sole caregivers for their elderly parents. DESIGN: Semistructured in-depth interviews. SETTING: Family practice clinic attached to a large tertiary care centre in north central Toronto. PARTICIPANTS: A convenience sample of 10 men who identified themselves as sole caregivers in that they had no particular women assisting them with caregiving. METHOD: Interviews were analyzed by standard qualitative methods. MAIN FINDINGS: Emerging themes were the spectrum of caregiving, the experience of caregiving, and the use of formal support systems. Scope of care varied from very little to total care, including personal care. Participants described positive and negative aspects of and the nature of their relationships with those for whom they cared. Avoiding institutionalization was seen as positive; effects on work and social life were negative. Use of more than homemaking services was associated with previous hospitalization; participants complained about difficulties accessing services. CONCLUSIONS: The nature of sons' relationships with their parents and the amount of time they have available can predict how much caregiving they can undertake. Information about community support services is not readily accessible to these men. PMID:10690492

    Previous studies have found a clear relationship between prolactin (prl) and paternal care in various vertebrate taxa. In New World monkeys, it has been demonstrated in several species that fathers have high prolactin levels even during periods without infant rearing. In this study, we followed the reproductive careers of common marmoset males as they transitioned from being an adult son within their native family to fathering their own offspring for the first time. Specifically, we examined the first experience of elevated prolactin levels in marmoset males. Additionally, we investigated the effects of the total number of experienced births as well as of age on prolactin levels. Our results show that common marmoset males did not experience an increase in prolactin secretion after pairing or shortly before birth of their first infants. However, prolactin levels rose more than twofold after the birth of their first infants and had lowered again 2.5 months after this event. We found no correlation between prolactin levels and the number of previous births experienced or age. Our study demonstrates that further work about a possible enhancing effect of prolactin on paternal care, by means of experimentally reducing hormonal levels, should be conducted in common marmosets using first-time fathers before males experience the first paternal increase in prolactin levels.

    Mothers with a history of child sexual abuse report less warmth toward their children, but whether this association differs by child gender is unknown. We examined the association of maternal child sexual abuse and warmth across child gender, accounting for depression, post-traumatic stress disorder, and child physical abuse. We verbally administered self-report measures to a cross-sectional sample of 154 mothers with a child between 8 and 12 years old. Eighty-five mothers based warmth responses on a son, and 69 on a daughter. We conducted a hierarchical multiple regression, including child gender, maternal child sexual abuse, child physical abuse, depression, post-traumatic stress disorder, and 4 two-way interaction terms with child gender. Maternal depression predicted decreased warmth, regardless of child gender, and maternal child sexual abuse predicted decreased warmth, but only toward daughters. Given previous research suggesting that maternal warmth predicts child well-being, the current finding may represent an important avenue of intergenerational transmission of risk in girls.

    Le syndrome de Tolosa Hunt (STH) est une ophtalmoplégie douloureuse due à une inflammation idiopathique et chronique de la fissure orbitaire supérieure ou du sinus caverneux. Le diagnostic répond à des critères cliniques et radiologiques précis. L'habituelle régression spontanée en quelques semaines est spectaculairement raccourcie par la corticothérapie. L'existence même de ce syndrome fut longtemps débattue et son cadre nosologique discuté. Nous rapportons le cas d'une patiente de 65 ans présentant une ophtalmoplégie complète du nerf oculomoteur commun. Le diagnostic de syndrome de Tolosa Hunt a été retenu après avoir éliminé toutes les autres causes de cette ophtalmoplégie, à savoir, les causes tumorales, vasculaires, métaboliques et infectieuses, et aussi devant l'amélioration spectaculaire sous corticothérapie générale. Le syndrome de Tolosa Hunt est maintenant une entité anatomo-clinique bien définie mais très peu fréquente. Il reste un diagnostic d’élimination, il est évoqué après une enquête étiologique minutieuse. Son traitement repose essentiellement sur la corticothérapie générale associé à un suivi méticuleux.

    L'objectif était d'identifier les facteurs de succès de la ligature bilatérale des artères hypogastriques et évaluer sa place dans le traitement chirurgical des hémorragies du post-partum. Nous avons réalisé une étude rétrospective regroupant tous les cas d'hémorragie du post-partum ayant nécessité un traitement chirurgical entre Janvier 2008 et Décembre 2011. L'étude a concerné 88 patientes (0,47% du total des accouchements). L'atonie utérine était l'étiologie la plus fréquente (64,8 % des patientes). La ligature bilatérale des artères hypogastriques a été réalisée chez 81,8% des patientes. Quand elle était le premier geste chirurgical réalisé, son taux de succès était de 66%. Ce taux était variable en fonction de l'étiologie de l'hémorragie, de la présence ou non de troubles de l'hémostase et du temps écoulé entre le diagnostic et la réalisation du geste chirurgical.

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

    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

  14. Non-genomic transmission of paternal behaviour between fathers and sons in the monogamous and biparental California mouse.

    Maternal behaviour has profound, long-lasting implications for the health and well-being of developing offspring. In the monogamous California mouse (Peromyscus californicus), care by both parents is critical for offspring survival. We tested the hypothesis that similar to maternal care in rodents, paternal huddling and grooming (HG) behaviour can be transmitted to future generations via behavioural mechanisms. In California mice, testosterone maintains paternal HG behaviour. In the present study, we randomly assigned a group of male California mice to castration or sham-operated conditions and allowed them to raise their offspring normally. Adult sons of these males were paired with a female, and they were observed interacting with their own offspring. We found that like their fathers, the sons of castrated males huddled and groomed their young at lower levels than the sons of sham-operated fathers. The sons of castrates also retrieved pups more frequently. When both parents were present, the sons of castrates also showed a trend towards engaging in less exploratory behaviour. These data support the hypothesis that paternal behaviour, like maternal behaviour, can be transferred to future generations via epigenetic mechanisms and suggest that in a biparental species both parents contribute to offspring behavioural development.

    Young black men who have sex with men (YBMSM) are experiencing high and rising rates of HIV infection, more than any other age-risk group category in the USA. Contributors to HIV risk in this group remain incompletely elucidated. We conducted exploratory qualitative interviews with 20 HIV-positive YBMSM aged 17-24 and found that father-son relationships were perceived to be important sociocontextual influences in participants' lives. Participants discussed the degree of their fathers' involvement in their lives, emotional qualities of the father-son relationship, communication about sex, and masculine socialization. Participants also described pathways linking father-son relationships to HIV risk, which were mediated by psychological and situational risk scenarios. Our thematic analysis suggests that father-son relationships are important to the psychosocial development of YBMSM, with the potential to either exacerbate or attenuate sexual risk for HIV. Interventions designed to strengthen father-son relationships may provide a promising direction for future health promotion efforts in this population.

    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

    Des conducteurs organiques fortement anisotropes presentent, sous l'effet d'un champ magnetique, une etonnante variete de proprietes physiques tel que: l'effet Shubnikov-de Haas, l'effet de Haas-van-Alphen, l'existence de cascades d'ondes de densite de spin apparentees a l'effet Hall quantique, reentrance vers la phase metallique pouvant provenir d'un 'breakdown' magnetique, et tout recemment la possibilite d'un confinement charge induit par le champ magnetique. A cela s'ajoute les nombreuses caracteristiques deja apparues en variant la pression hydrostatique ou la substitution chimique: separation spin-charge, localisation de la charge, transition spin-Peierls, antiferromagnetisme itinerant ou non, supraconductivite, et l'existence d'une frontiere commune entre les phases supraconductrice et antiferromagnetique. En vue de completer la description theorique du diagramme de phase generalise des conducteurs organiques, nous adaptons et elargissons la methode du groupe de renormalisation quantique (GRQ) au cas ou le champ magnetique est non nul. On sait deja que cette methode permet de resoudre le dilemme tout particulier des composes Q-1D, soit leur capacite de produire des transitions de phase malgre leur forte anisotropie et consequemment de leur faible dimensionalite. Cette methode est deja utilisee pour decrire le diagramme de phase temperature versus pression des sels de Bechgaard, de leurs analogues souffres et mixtes. Le GRQ permet aussi de comprendre comment des systemes anisotropes comme les conducteurs organiques peuvent se comporter comme des liquides de Luttinger a haute temperature et comme des liquides de Fermi ou condenses a basse temperature. Nous montrons que l'introduction d'un champ magnetique dans un regime de saut coherent interchai ne a deux particules n'apporte que de simples corrections aux lois d'echelles dans le canal zero son, alors qu'il introduit un mecanisme de brisure de paire dans le canal Cooper.

    This article explores the persistence of son preference in a patrilineal, patrilocal society in the midst of fertility decline. Using survey and ethnographic data from Hindu-caste Nepali families in a semiurban village, I analyze which cultural norms regarding reproduction are questioned by contemporary married couples and which remain intact. Despite modest improvements in gender equality, levels of education, and economic conditions, the practical knowledge that daughters will be lost to other lineages and households pressures couples who might otherwise be willing to invest in daughters to continue procreating until they produce a son. Young mothers, therefore, reluctantly admit to needing a son, revealing a discrepancy between their initially stated reproductive ideals and their ultimate behavior. PMID:21466108

    The authors examined the communication of affection in men's relationships with their fathers. Drawing from Affection Exchange Theory, the authors advanced four predictions: (a) heterosexual men receive more affection from their own fathers than do homosexual or bisexual men, (b) fathers communicate affection to their sons more through supportive activities than through direct verbal statements or nonverbal gestures, (c) affectionate communication between fathers and sons is linearly related to closeness and interpersonal involvement between them, and (d) fathers' awareness of their sons' sexual orientation is associated with the amount of affection that the fathers communicate to them. Participants were 170 adult men who completed questionnaires regarding affectionate communication in their relationships with their fathers. Half of the men were self-identified as exclusively heterosexual, and the other half were self-identified as exclusively homosexual or bisexual. The results supported all predictions substantially.

  4. I-SonReb: an improved NDT method to evaluate the in situ strength of carbonated concrete

    Concrete strength evaluated in situ by means of the conventional SonReb method can be highly overestimated in presence of carbonation. This latter, in fact, is responsible for the physical and chemical alteration of the outer layer of concrete. As most of the existing concrete structures are subjected to carbonation, it is of high importance to overcome this problem. In this paper, an Improved SonReb method (I-SonReb) for carbonated concretes is proposed. It relies on the definition of a correction coefficient of the measured Rebound index as a function of the carbonated concrete cover thickness, an additional parameter to be measured during in situ testing campaigns. The usefulness of the method has been validated showing the improvement in the accuracy of concrete strength estimation from two sets of NDT experimental data collected from investigations on real structures.

    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.

    2016-07-01

    We present the proposal for the physical instrument model of the SOXS (Son OF X-Shooter) spectroscopic facility mainly devoted to the follow-up observation of transient sources. A dedicated suitable instrument to exploit the science of these transients is lacking, resulting in severe science "dissipation". SOXS will cover the optical/NIR band (0.35-1.75 μm) with a medium resolution (R 4500), down to the limiting magnitude of R 20-20.5 (1 hr at S/N 10) that is perfectly suited to study transients from on-going imaging surveys. Imaging capabilities in the optical are also foreseen to allow for multi-band photometry of the faintest transients with a field of view of at least 2arcmin. We propose to implement a physical modelling approach in order to link the instrument parameters and behaviour to physical quantities, thus providing a description of the instrument that can be connected with measurements. The method has been already successfully applied to the X-shooter instrument. The X-shooter physical model is based on a kernel optical ray-tracing realised by means of matrix optics representation, which can handle a large number of wavelengths. This can be extended to the SOXS design. The foreseen applications of the SOXS physical model are broad, ranging from support to detailed instrument design and development of the data reduction software, wavelength calibration, evaluation of instrument performance as a function of the model parameters, instrument alignment, and support during the commissioning phase and as a tool for quality check during operations.

    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.

    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.

    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.

    Cette these est consacree a l'histoire de l'electrification rurale du Quebec, et, plus particulierement, a l'histoire des cooperatives d'electricite. Fondees par vagues successives a partir de 1945, les cooperatives rurales d'electricite ont ete actives dans plusieurs regions du Quebec et elles ont electrifie une partie significative des zones rurales. Afin de comprendre le contexte de la creation des cooperatives d'electricite, notre these debute (premiere partie) par une analyse du climat sociopolitique des annees precedant la naissance du systeme cooperatif d'electrification rurale. Nous y voyons de quelle facon l'electrification rurale devient progressivement, a partir de la fin des annees 1920, une question d'actualite a laquelle les divers gouvernements qui se succedent tentent de trouver une solution, sans engager---ou si peu---les fonds de l'Etat. En ce sens, la premiere etatisation et la mise sur pied d'Hydro-Quebec, en 1944, marquent une rupture quant au mode d'action privilegie jusque-la. La nouvelle societe d'Etat se voit cependant retirer son mandat d'electrifier le monde rural un an apres sa fondation, car le gouvernement Duplessis, de retour au pouvoir, prefere mettre en place son propre modele d'electrification rurale. Ce systeme repose sur des cooperatives d'electricite, soutenues par un organisme public, l'Office de l'electrification rurale (OER). L'OER suscite de grandes attentes de la part des ruraux et c'est par centaines qu'ils se manifestent. Cet engouement pour les cooperatives complique la tache de l'OER, qui doit superviser de nouvelles societes tout en assurant sa propre organisation. Malgre des hesitations et quelques delais introduits par un manque de connaissances techniques et de personnel qualifie, les commissaires de l'OER se revelent perspicaces et parviennent a mettre sur pied un systeme cooperatif d'electrification rurale qui produit des resultats rapides. Il leur faudra cependant compter sur l'aide des autres acteurs engages

    Histological and cytological analyses of the testes were carried out in 42 sterile sons of males treated in the spermatozoal or spermatid stage with 250 mg/kg ethyl methanesulfonate (EMS) alone or after prefeeding with butylated hydroxytoluene (BHT); or treated with 200 R X-rays. Of the 42 sterile males, 17 had some mature spermatids, nine were blocked at diakinesis, 15 were blocked in pachytene, and one lacked spermatogenic cells altogether, having Sertoli cells only. Mitotic (spermatogonial) metaphases could therefore be analyzed in 41 of the males and meiotic configurations in 26.—(1) None of the males showed abnormalities in chromosome number, such as monosomy, trisomy, or mosaicism for either of these conditions. Certain classes of chromosome abnormalities that have been found associated with male sterility in other investigations, namely trisomies, XXY's, and X-autosome translocations, are not expected from treatment of 19A + Y cells when F1 males are studied. (2) A very high percentage of the sterile males carried translocations. Direct meiotic evidence for this was found in 22 of the animals. In addition, 11 of the 16 that were blocked (or virtually blocked) in pachytene, and thus could be analyzed in mitosis only, consistently showed one abnormally short chromosome (or, one short plus one long), which presumably had resulted from unequal exchange (or sizable deficiency). Of the meiotically detected translocation males, 1 carried a T(A;Y), 17 had single autosomal translocations, and 4 had multiple autosomal rearrangements involving three, four, four, and six breaks, respectively. In addition, three males showed failure of X-Y pairing. (3) Translocations that cause sterility, rather than partial sterility, in males appear to be those in which at least one of the breaks occurs close to one end of a chromosome. The mitotic and meiotic evidences for this were found to be correlated. (4) It is proposed that many cases of induced F1 male sterility may be the

    The Birmingham Solar Oscillations Network (BiSON) has provided high-quality high-cadence observations from as far back in time as 1978. These data must be calibrated from the raw observations into radial velocity and the quality of the calibration has a large impact on the signal-to-noise ratio of the final time series. The aim of this work is to maximize the potential science that can be performed with the BiSON data set by optimizing the calibration procedure. To achieve better levels of signal-to-noise ratio, we perform two key steps in the calibration process: we attempt a correction for terrestrial atmospheric differential extinction; and the resulting improvement in the calibration allows us to perform weighted averaging of contemporaneous data from different BiSON stations. The improvements listed produce significant improvement in the signal-to-noise ratio of the BiSON frequency-power spectrum across all frequency ranges. The reduction of noise in the power spectrum will allow future work to provide greater constraint on changes in the oscillation spectrum with solar activity. In addition, the analysis of the low-frequency region suggests that we have achieved a noise level that may allow us to improve estimates of the upper limit of g-mode amplitudes.

    The lack of success of the "coming out" studies over the last three decades to explain and predict parental responses has motivated an evolutionary psychological reconceptualization. According to this reconceptualization, it was predicted that (a) biological mothers would experience more distress and apply more pressure on gay sons to change than would biological fathers and; (b) obligate investment for fathers on dependent sons would cause fathers to experience more distress and apply more pressure on gay sons to change than it would fathers without this obligate investment. In contrast, a cultural-norm hypothesis predicted that fathers would experience more distress and apply more pressure on gay sons to change than mothers. The majority of predictions were tested using 787 participants from two-biological parent families, who were drawn from a total sample of 891 participants from various family backgrounds. As predicted by the evolutionary hypothesis, biological mothers were reported to have been more distressed and coercive than biological fathers, in spite of a strong, societal expectation to the contrary. Furthermore, the results supported the obligate investment argument for paternal reactions. The model not only correctly explained and predicted parental behavior during coming out, but also was shown to unify within its theoretical framework discrepant results from the literature previously considered inconsistent.

  11. The Solar Core: New Low-l p-Mode Fine-Spacing Results from BiSON

    The fine-structure spacing dl(n) = νl,n - νl+2,n-1 for low-degree solar p modes of angular degree l and radial order n is sensitive to conditions in the deep radiative interior of the Sun. Here we present fine-structure spacings derived from the analysis of nearly 5 years of helioseismological data collected between 1991 July and 1996 February by the Birmingham Solar Oscillations Network (BiSON). These data cover 9 <= n <= 28 for d0(n), and 11 <= n <= 27 for d1(n). The measured spacings are much more precise and cover a greater range than earlier measurements from BiSON data (Elsworth et al. 1990a). The predicted fine-structure spacings for a ``standard'' solar model are clearly excluded by the BiSON data (at ~10 σ) models that include helium and heavy-element settling provide a much better match to the observed spacings (see also Elsworth et al. 1995). Since the inclusion of core settling in solar models will tend to increase slightly the predicted neutrino flux, the BiSON fine-structure data appear to reinforce previous conclusions, i.e., an astrophysical solution to the solar neutrino problem seems unlikely.

    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.

    2006-07-01

    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.

    Résumé La politique actuelle de lutte contre le sida qui repose sur l’extension de l’accès aux traitements et à la prévention exige qu’une proportion élevée de la population connaisse son statut en matière de VIH. Pour cela, l’OMS a proposé le développement de stratégies communautaires délivrant le dépistage et le conseil au-delà des services de soins, comme le test à domicile ou les campagnes de sensibilisation et dépistage de grande envergure, appliqués en Afrique australe et de l’Est. Pour définir les stratégies pertinentes dans des régions de basse prévalence comme l’Afrique de l’Ouest, les expériences communautaires de promotion du dépistage doivent y être évaluées. Cet article présente une évaluation des campagnes au Burkina Faso du point de vue des usagers. Dans le cadre d’un projet sur les pratiques et l’éthique du dépistage dans quatre pays africains (MATCH), une enquête qualitative spécifique a été menée pendant la campagne de 2008, auprès de personnes ayant fait le test pendant la campagne, ayant fait le test hors campagne ou n’ayant pas fait le test. Les appréciations sont globalement très favorables aux campagnes, notamment à cause de l’information dispensée, l’accessibilité des sites, la gratuité du test, la qualité des services et l’effet d’entrainement. Les limites ou critiques sont essentiellement liées à l’affluence ou à la crainte de ne pas être soutenu en cas de résultat positif. La démarche de recours au test ne fait plus l’objet de suspicion, au moins pendant la campagne. Cette « normalisation » du recours au test et la mobilisation collective facilitent des pratiques en groupe, ce qui peut rendre difficile de garder son statut VIH secret. L’évaluation des campagnes par les usagers les présente comme une opportunité pour accéder facilement au test et pour communiquer à ce sujet dans divers espaces sociaux à partir des informations délivrées sur le VIH

    2008-09-01

    À l'heure des projets de télescopes extrêmement grands, l'Europe a déjà une longueur d'avance. Le télescope européen (VLT), en mode interférométrique avec l'instrument AMBER devient le plus grand télescope jamais utilisé dans le domaine optique aussi bien en surface de miroir (plus de 150 m2) qúen finesse de résolution qui atteint celle d'un télescope de 130 m de diamètre. Le journal professionnel Astronomy & Astrophysics a publié en 2007 un numéro spécial qui rapporte les premiers résultats obtenus avec l'instrument AMBER (Astronomical MultiBEam Recombiner) par le très grand télescope européen. Ces articles couvrent pratiquement tous les stades de l'évolution stellaire depuis la formation des étoiles et des planètes jusqu'a l'observation de l'explosion de type nova dans un système stellaire évolué. Ces résultats inédits ont été obtenus en utilisant simultanément 3 des 4 télescopes du VLT basés à l'Observatoire européen austral du mont Paranal au Chili. L'instrument AMBER équipant le VLTI (mode interférométrique du VLT) permet dâatteindre une résolution angulaire inégalée de l'ordre du millième de seconde d'angle autorisant l'observation des astres dans différentes longueurs d'onde, dans l'infrarouge proche. Les astronomes obtiennent donc des observations avec une finesse 13 fois plus importante que celle d'un télescope seul. Il devient alors possible de sonder les régions de formation de planètes, d'observer les vents des étoiles en rotation très rapide, d'étudier les différents types de matières éjectées par une étoile massive, de séparer les deux composantes d'une étoile double serrée et de voir en direct l'évolution d'une nova quelques jours seulement après son explosion.

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

    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.

    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

    Carl Wilhelm Naundorff was buried in 1845 in Delft as Louis Charles, Duc de Normandie, 'Louis XVII'. However, the son of Louis XVI and Marie-Antoinette-Louis XVII--officially died in the Temple of Paris in 1795. In order to resolve the identity of Naundorff, mitochondrial DNA (mtDNA) D-loop sequences of his remains were compared with the sequences obtained from the hairs of two sisters of Marie-Antoinette, Marie-Antoinette herself, and with the sequences obtained from DNA samples of two living maternal relatives. The mtDNA sequence of a bone sample from Naundorff showed two nucleotide differences from the sequences of the three sisters and four differences from the sequences of living maternal relatives. Based on this evidence it becomes very unlikely that Naundroff is the son of Marie-Antoinette.

    Drawing on ecological and gender socialization perspectives, this study examined mothers’ and fathers’ relationships with young adolescents, exploring differences between mothers and fathers, for sons versus daughters, and as a function of parents’ division of paid labor. Mexican immigrant families (N = 162) participated in home interviews and seven nightly phone calls. Findings revealed that mothers reported higher levels of acceptance toward adolescents and greater knowledge of adolescents’ daily activities than did fathers, and mothers spent more time with daughters than with sons. Linkages between parent-adolescent relationship qualities and youth adjustment were moderated by adolescent gender and parents’ division of paid labor. Findings revealed, for example, stronger associations between parent–adolescent relationship qualities and youth adjustment for girls than for boys. PMID:19779582

    We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDFs). This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parameterized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of 'Beyond the Standard Model' physics.

  3. Amelioration de l'efficacite energetique du procede d'electrolyse de l'aluminium conception d'un nouveau bloc cathodique

    Blais, Mathieu

    Au Quebec, les alumineries sont de grandes consommatrices d'energie electrique, soit pres de 14 % de la puissance installee d'Hydro-Quebec. Dans ce contexte, des petits gains en efficacite energetique des cuves d'electrolyse pourraient avoir un impact important sur la reduction globale de la consommation d'electricite. Le projet de maitrise decrit dans cette etude repond a la problematique suivante : comment l'optimisation de la geometrie d'un bloc cathodique en vue d'uniformiser la densite de courant peut augmenter l'efficacite energetique et la duree de vie de la cuve d'aluminium? Le but premier du projet est de modifier la geometrie en vue d'ameliorer le comportement thermoelectrique des blocs cathodiques et d'accroitre par le fait meme l'efficacite energetique du procede de production d'aluminium. La mauvaise distribution de la densite de courant dans la cuve est responsable de certains problemes energetiques ayant des impacts negatifs sur l'economie et l'environnement. Cette non-uniformite de la distribution du courant induit une usure prematuree de la surface de la cathode et contribue a reduire la stabilite magnetohydrodynamique de la nappe de metal liquide. Afin de quantifier les impacts que peut avoir l'uniformisation de la densite de courant a travers le bloc cathodique, un modele d'un bloc cathodique d'une cuve de la technologie AP-30 a ete concu et analyse par elements finis. A partir de son comportement thermoelectrique et de donnees experimentales d'une cuve AP-30 tirees de la litterature, une correlation entre le profil de densite de courant a la surface du bloc et le taux d'erosion local au meme endroit a ete creee. Cette relation correspond au modele predictif de la duree de vie de tout bloc du meme materiau a partir de son profil de densite de courant. Ensuite, une programmation a ete faite incorporant dans une meme fonction cout les impacts economiques de la duree de vie, de la chute de voltage cathodique et de l'utilisation de nouveaux materiaux

  4. An X-Linked Sex Ratio Distorter in Drosophila simulans That Kills or Incapacitates Both Noncarrier Sperm and Sons

    PubMed Central

    Rice, William R.

    2014-01-01

    Genomic conflict occurs when a genomic component gains a reproductive advantage at the expense of the organism as a whole. X-linked segregation distorters kill or incapacitate Y-bearing sperm, thereby gaining a transmission advantage but also reducing male fertility and generating a female-biased sex ratio. When some damaged, Y-bearing sperm survive and fertilize eggs, then the segregation distortion phenotype could be expanded by harming or killing sons in the next generation. X-linked son-killers are predicted by theory to be favored by natural selection and evolve when brothers and sisters compete for shared limiting resources and/or when brothers reduce the inclusive fitness of their sisters via sib-mating—a phenomenon called SA-zygotic drive. Here I develop and use a process-of-elimination screen to show that an unclassified X-linked sex ratio distorter (skew) in Drosophila simulans kills or incapacitates noncarrier sperm and also kills a substantial proportion of sons, i.e., it has both a segregation distortion and a SA-zygotic drive phenotype. There are three unique X-linked segregation distorters known to occur in D. simulans named Winters, Durham, and Paris. Autosomal-dominant suppressors of Winters (Nmy) and Durham (Tmy) failed to suppress skew. A Y-linked suppressor of Paris, however, did suppress skew, and a recombination test failed to detect recombinants between these two sex ratio distorters, indicating that they are tightly linked and plausibly identical or allelic. Son-killing may be an important yet unrecognized component of other X-linked segregation distorters. PMID:25081980

    SUMMARY Dysregulation of MLL complex-mediated histone methylation plays a pivotal role in gene expression associated with diseases, but little is known about cellular factors modulating MLL complex activity. Here, we report that SON, previously known as an RNA splicing factor, controls MLL complex-mediated transcriptional initiation. SON binds to DNA near transcription start sites, interacts with menin, and inhibits MLL complex assembly, resulting in decreased H3K4me3 and transcriptional repression. Importantly, alternatively spliced short isoforms of SON are markedly upregulated in acute myeloid leukemia. The short isoforms compete with full-length SON for chromatin occupancy, but lack the menin-binding ability, thereby antagonizing full-length SON function in transcriptional repression while not impairing full-length SON-mediated RNA splicing. Furthermore, overexpression of a short isoform of SON enhances replating potential of hematopoietic progenitors. Our findings define SON as a fine-tuner of the MLL-menin interaction and reveal short SON overexpression as a marker indicating aberrant transcriptional initiation in leukemia. PMID:26990989

    We prospectively studied parental mental health after suddenly losing a son in a military training accident. Parents (N = 32) were interviewed at 1, 2 and 23 years after the death of their son. The General Health Questionnaire and Expanded Texas Inventory of Grief were self-reported at 1, 2, 5, and 23 years; the Inventory of Complicated Grief was self-reported at 23 years. We observed a high prevalence of psychiatric disorders at 1- and 2-year follow-ups (57% and 45%, respectively), particularly major depression (43% and 31%, respectively). Only one mental disorder was diagnosed at the 23-year follow-up. Grief and psychological distress were highest at 1- and 2-year follow-ups. Spouses exhibited a high concordance of psychological distress. Mothers reported more intense grief reactions than did fathers. The loss of a son during military service may have a substantial impact on parental mental health particularly during the first 2 years after death. Spouses' grief can be interrelated and may contribute to their psychological distress.

  8. "Wenn ich leben soll, so sei es mit dir!" The relationship of father and son in Goethe's "Wilhelm Meisters Wanderjahre".

    PubMed

    Lee, Charlotte

    2011-01-01

    The relationship between father and son is a highly nuanced and persistent theme in Goethe's late novel Wilhelm Meisters Wanderjahre, but has received relatively little critical attention. Drawing on various aspects of the text, from the relationship between Wilhelm and his own son Felix, to the theme of migration from the ‘fatherland’, this essay contends that the relationship of the younger generation to the older traces a pattern of departure and return. The development in the son of an identity distinct and independent from that of the father is a preoccupation of the earlier chapters of the Wanderjahre in particular; but this process of individuation tends to be accompanied in the novel by continued, even increased, identification with the father, which may be conscious or unconscious. All the various stages of this fluctuating relationship are telescoped into a few rich, enigmatic images in the novel's closing scene, in which the threat of separation and the desire for proximity are held in suspension.

    La pubalgie du sportif de haut niveau représente une entité nosologique à part entière, tant en raison du mécanisme à l'origine de la pathologie que des lésions objectivables au niveau de la paroi abdominale. C'est un syndrome douloureux de la région inguino-pubienne qui touche particulièrement les footballeurs. Son étiologie est attribuée à la répétition de mouvements des membres inférieurs et du tronc associant rotation et adduction forcées. Son incidence est nettement plus élevée chez les hommes. Après avoir écarté une pathologie d'organe, le patient devrait bénéficier tout au début de son traitement conservateur d'une IRM afin d'effectuer un bilan lésionnel complet qui, selon les situations, permet d’écourter le traitement conservateur et de proposer un traitement chirurgical optimal. Le traitement doit être résolument conservateur pendant 3 mois. La rééducation est le plus souvent le traitement de première intention. Les patients présentant une persistance des symptômes sont candidats à la chirurgie. L'intervention de Nesovic est le traitement de choix chez les sportifs de haut niveau et qui permet, dans la très grande majorité des cas, une reprise sans aucune limitation de l'activité sportive antérieure. La technique de Bassini semble être moins lourde que celle de Nesovic, puisqu'elle est moins invasive. Une prise en charge multidisciplinaire centrée sur l'athlète avant et après l'intervention permet un retour aux activités physiques après quelques mois. Nous rapportons l'expérience de la prise en charge de 128 joueurs opérés selon la technique de Bassini et nous comparons nos résultats avec celles de la littérature. PMID:26966484

    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

  12. Mothers, fathers, sons, and daughters: gender differences in factors associated with parent-child communication about sexual topics

    PubMed Central

    2010-01-01

    Background In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Methods Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. Results With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age. Conclusions Using a large national sample, this study confirms findings from previous studies showing gender differences in parent-child communication about sexual topics

    The SonTek Argonaut SL Side-Looking Doppler Current Meters are well established products in the measurement of real-time water velocity in open channels. With the development of acoustic doppler technology the decision was made to incorporate latest technology in the Argonaut SL and hence the SonTek SL3G was born.The SonTek SL3G Acoustic Doppler instrument incorporates a number of innovations that improves velocity measurements and quality assurance of data for Side-Looking Doppler Current Meters. SmartPulseHD was originally introduced with the launch of the SonTek M9/S5 RiverSurveyor Acoustic Doppler Instruments and the increased accuracy and resolution of velocity measurements made it obvious to include into the new SL3G instruments. SmartPulseHD continuously tracks the water conditions and selects the optimum processing configuration required using multiple ping types and processing techniques. The new SL3G design makes it the smallest Side Looking Acoustic Doppler Velocity Meter on the market reducing flow disturbance caused by the instrument and the distance of first measurement cell from boundary.The application of the SL3G Acoustic Doppler instrument is designed for complex flow conditions where the use of conventional stage-discharge relationships is economically not viable and therefore requires the use of velocity index methodology. The case-study presented in this paper is situated in the Colorado River downstream of Imperial Dam affected by controlled releases, drainage from adjacent irrigation areas and backwater from a weir situated downstream of the monitoring site. The paper analyses the relationship between measured mean velocity and index velocity and if additional variables such as stage and or Y-velocity need to be incorporated in the development of the index velocity rating. In addition, to determine the variables impacting on the index velocity rating, the index velocity applied will be evaluated by the best linear relationship between the

  14. Effect of Callovo-Oxfordian clay rock on the dissolution rate of the SON68 simulated nuclear waste glass

    Long-term storage of high-level nuclear waste glass in France is expected to occur in an engineered barrier system (EBS) located in a subsurface Callovo-Oxfordian (COx) clay rock formation in the Paris Basin in northeastern France. Understanding the behavior of glass dissolution in the complex system is critical to be able to reliably model the performance of the glass in this complex environment. To simulate this multi-barrier repository scenario in the laboratory, several tests have been performed to measure glass dissolution rates of the simulated high-level nuclear waste glass, SON68, in the presence of COx claystone at 90 °C. Experiments utilized a High-Performance Liquid Chromatography (HPLC) pump to pass simulated Bure site COx pore water through a reaction cell containing SON68 placed between two COx claystone cores for durations up to 200 days. Silicon concentrations at the outlet were similar in all experiments, even the blank experiment with only the COx claystone (∼4 mg/L at 25 °C and ∼15 mg/L at 90 °C). The steady-state pH of the effluent, measured at room temperature, was roughly 7.1 for the blank and 7.3-7.6 for the glass-containing experiments demonstrating the pH buffering capacity of the COx claystone. Dissolution rates for SON68 in the presence of the claystone were elevated compared to those obtained from flow-through experiments conducted with SON68 without claystone in silica-saturated solutions at the same temperature and similar pH values. Additionally, through surface examination of the monoliths, the side of the monolith in direct contact with the claystone was seen to have a corrosion thickness 2.5× greater than the side in contact with the bulk glass powder. Results from one experiment containing 32Si-doped SON68 also suggest that the movement of Si through the claystone is controlled by a chemically coupled transport with a Si retention factor, Kd, of 900 mL/g.

    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.

    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.

  17. 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.

    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.

    Résumé Objectif Offrir des conseils préliminaires sur la prescription de cannabis fumé pour la douleur chronique avant la publication de lignes directrices officielles. Qualité des données Nous avons examiné les ouvrages scientifiques sur l’efficacité analgésique du cannabis fumé et les dommages causés par la consommation de cannabis à des fins médicales et récréatives. Nous avons élaboré des recommandations concernant les indications et les contre-indications du cannabis fumé, les précautions à prendre et son dosage et nous avons classé les recommandations en fonction du niveau des données probantes. La plupart des données probantes sont de niveau II (études observationnelles bien effectuées) et de niveau III (opinion d’experts). Message principal Le cannabis fumé pourrait être indiqué chez des patients souffrant de douleurs neuropathiques sévères qui n’ont pas répondu à des essais suffisants de cannabinoïdes pharmaceutiques et d’analgésiques standards (données probantes de niveau II). Le cannabis fumé est contre-indiqué chez les patients de 25 ans ou moins (données probantes de niveau II); ceux qui font actuellement ou ont fait par le passé une psychose ou encore ont de forts antécédents familiaux de psychose (données probantes de niveau II); ceux qui ont ou ont eu un problème de consommation de cannabis (données probantes de niveau III); ceux qui ont un problème actuel de toxicomanie ou d’alcoolisme (données probantes de niveau III); ceux qui ont une maladie cardiovasculaire ou respiratoire (données probantes de niveau III); ou celles qui sont enceintes ou planifient une grossesse (données probantes de niveau II). Il devrait être utilisé avec précaution par les patients qui fument du tabac (données probantes de niveau II), qui sont à risque accru de maladies cardiovasculaires (données probantes de niveau III), qui ont des troubles d’anxiété ou de l’humeur (données probantes de niveau II) ou

    2007-09-01

    The role of the father in the onset and development of schizophrenic disorder/disturbance is very often secondary as compared to that of the mother. This study deals with the father's sphere in the family with a patient/son suffering from schizophrenia, the traits of his personality and his relationship with his son/patient, and with his wife/the mother of the patient. The methods applied were clinical interview, structured interview and semantic differential. The following statistical procedures were used: correlation, componential, discriminative, factor and quasicanonical analyses. The results include some characteristic excerpts from clinical interviews with patients/sons and their fathers, projective perception of current family relationships, quasicanonical analysis of the father's, mother's and son's experiences of the patient's/son's early childhood, and the projective view of the father. Among the conclusions reached, the phenomenon of "dead father" is emphasized as one of the main factors in the onset and development of schizophrenic disorder/disturbance.

    2015-10-09

    We introduce a simple model of SO(N) spins with two-site interactions which is amenable to quantum Monte Carlo studies without a sign problem on nonbipartite lattices. We present numerical results for this model on the two-dimensional triangular lattice where we find evidence for a spin nematic at small N, a valence-bond solid at large N, and a quantum spin liquid at intermediate N. By the introduction of a sign-free four-site interaction, we uncover a rich phase diagram with evidence for both first-order and exotic continuous phase transitions.

    Introduction La présente étude prospective se propose dévaluer l'efficacité thérapeutique du traitement préventif intermittent à la sulfadoxine - pyriméthamine et son observance chez la femme enceinte dans deux hôpitaux urbains au Burkina Faso. Méthodes Chaque femme répondant aux critères d'inclusion a été soumise à un questionnaire pour la collecte des données socio - démographiques et des renseignements sur la grossesse. A l'accouchement, une apposition placentaire a été réalisée systématiquement. La lecture a été faite au microscope à lobjectif 100 à immersion. Résultats Au total, 542 femmes ont été incluses avec un âge moyen de 26,0 ± 6,45 ans (extrêmes 13- 43 ans). Le taux de couverture du TPI à la sulfadoxine- pyriméthamine a été de 80%. Le taux d'infestation placentaire a été de 4,7%. Il a diminué avec le nombre de dose de traitement préventif intermittent. Il a augmenté cependant de juillet à octobre. De 42,9% en octobre, il a diminué significativement à 9,5% en novembre (p < 0,05). Le taux global de bonne d'observance a été de 55%. Il a augmenté avec l’âge (p < 0,05). Conclusion Le taux de couverture de la sulfadoxine - pyriméthamine a été de 80%. Ce résultat est en conformité avec les objectifs du plan stratégique 2006-2010 de lutte contre le paludisme au Burkina Faso, qui préconisait un taux de couverture en sulfadoxine - pyriméthamine de 80% pour 2010. L'augmentation de la fréquence d'infestation de juillet à octobre, serait liée à la recrudescence de la transmission palustre pendant la saison des pluies (mai-octobre). PMID:23717719

    Objectifs l’augmentation du taux de personnes qui connaissent leur statut VIH est un impératif, notamment en Afrique subsaharienne, ce qui impose d’évaluer les stratégies utilisées pour accroître la fréquentation des services de dépistage. Cet article vise à faire le bilan de la pertinence, de la faisabilité et de l’efficacité des campagnes nationales de dépistagemenées entre 2006 et 2010 au Burkina Faso. Méthodologie une analyse de toutes les données de fréquentation du conseil dépistage sur cette période a été faite, couplée à des entretiens avec les principaux acteurs intervenant dans le dépistage. Résultats les résultats montrent que les huit campagnes de dépistage organisées sur la période ont permis à 487 727 personnes de faire leur test VIH. Ce nombre représente 50 % du nombre total de personnes ayant fait leur test et contribue à hauteur de 24,6 % au dépistage des personnes séropositives identifiées au cours de cette période. Les campagnes ont touché des populations difficiles à atteindre (en particulier les jeunes), à un coût moindre. Conclusions cette stratégie est donc pertinente pour identifier les personnes VIH+. Son intérêt pour la prévention, important selon les soignants et au vu des populations jeunes qui y participent, devrait être mesuré par des études complémentaires. Les campagnes sont efficaces et coût-efficaces même dans un pays de niveau de prévalence faible. Ces résultats soulignent l’intérêt de la synergie entre les associations et les services de santé dans l’offre de services de conseil et dépistage. PMID:24681563

  16. La Mamora, charnière entre la Meseta et le Rif : son importance dans l'évolution géodynamique post-paléozoïque du Maroc

    The Mamora area (Morocco) is located in the northern part of the Meseta and the southern part of Rharb. The recent formations (Mesozoic to Quaternary) lie unconformably on a Paleozoic basement. This study based on hydrogeological, sedimentological, drilling data and seismic reflection profiles interpretation, proposes new interpretations of geodynamical evolution of this area particularly in terms of tectonic patterns. The most ancient formations recognized in this region are Paleozoic schists and quartzites in the Tiflete sector. They represent the basement of the basin on which Triassic conglomerates and red mudstones associated with basalts lie unconformably. Jurassic and Cretaceous sediments are limestones and marls. The Mio-pliocene formations are open marine blue marls. Plio-quaternary sediments are limestones and sands containing gravel and pebbles. Miocene to Pliocene blue marls facies corresponds to deep marine marls (bathyal as indicated by planctonic foraminifers) with an attributed age from upper Miocene 〚9〛 to middle Pliocene 〚7〛. A facies distribution map of the top of the blue marls has been realized where four main facies - conglomerate, shelly sandstone, limestone and marls - indicate a major regression in the Mamora basin. The datation of the formations was mostly realized by Wernli 〚22, 23, 24, 25〛, and Cirac 〚10〛. In the Mamora area, Hercynian faults show two main structural directions, N020°E-N040°E (Agadir-Rabat), N120°E (Rabat-Tiflète) 〚5〛, and a new major Hercynian fault (K2S). The seismic profiles have been studied between Sidi Slimane and Sidi Yahia area, to illustrate the structure of the Mamora, and to replace it, in the geodynamical evolution. The seismic reflection lines and drilling data show that the eastern Mamora was subdivided into two sectors : i) the southern sector is affected by Hercynian faults which create horsts and grabens in the Paleozoic. Mio-Pliocene formations infill these depressions and are covered by Quaternary sediments ; ii) the northern sector is constituted by various formations : 1. Paleozoic formation as basement covered by autochthonous Mesozoic to Miocene, 2. Prerifain nappes (marls and evaporites), 3. Mio-Plio-Pleistocene formations as subautochthonous to autochthonous. These two sectors are separated by a major fault (K2S). On the other hand, in the occidental Mamora, the facies distribution and the Plio-Pleistocene thickening seem to be induced by faults with a NE-SW and NW-SE trends which affect the Paleozoic basement. Then, between the Meseta domain and the septentrional Rharb basin, two major Hercynian initially dextral shear zones, Rabat-Tiflete and K2S, have been recognised. During the Atlantic Ocean opening, they are probably senestral shear zones. At the same time the subsidence in Rharb basin is active, major action of these faults is normal. Therefore, Mamora represents a real hinge between stable Meseta and unstable septentrional Rharb basin.

    The meandrous leveed channels of the Nile Cone show clear evidence of avulsions. Their sedimentary architecture is founded on numerous stacked lens-shaped acoustic units. In the areas of the distal fan, lobe deposits are apparent from multichannel imagery. Huge debris flow deposits, sometimes associated with pockmarks, are recognized. Mud volcanoes and gas seeping are closely associated with faulting. In the East, a very long north-trending channel, originating from the Egyptian coast, merges with a network of channels, very probably originating from the Levantine coasts. Both networks outlet in the sedimentary basin located south of Cyprus.

    Le stockage de l'hydrogene par adsorption sur des adsorbants nano-structures a ete etudie sous differentes conditions de pression et de temperature. Les adsorbants etudies sont principalement des nanotubes de carbone a simple paroi ainsi que des structures metallo-organiques. Les mesures ont ete realisees a l'aide de systemes gravimetriques et volumetriques tres sensibles specialement mis au point pour de petits echantillons necessitant un degazage in situ. Les appareils developpes, au nombre de quatre, comprennent deux systemes gravimetriques et deux systemes volumetriques. Ensemble, ces systemes couvrent la plage de pressions (0-100) bars ainsi que la plage de temperatures (77-295) K. Les differentes analyses montrent que l'adsorption d'hydrogene sur les adsorbants nano-structures etudies est maximale a 77 K et varie entre environ (1.5 et 4) % masse. A temperature ambiante, l'adsorption croit lineairement avec la pression et demeure sous les 1% masse pour des pressions inferieures a 100 bars. L'adsorption d'hydrogene sur ces materiaux dans ces conditions se compare notamment a celle obtenue sur des charbons actives. La modelisation de l'adsorption a egalement ete realisee dans des conditions cryogeniques a l'aide du modele de Dubinin-Astakhov sous une forme adaptee pour l'adsorption supercritique. Les enthalpies d'adsorption calculees a partir de ce modele varient sous les 6 kJ/mole et sont donc consistantes avec des processus de physisorption. L'applicabilite du modele de Dubinin-Astakhov suggere que l'adsorption d'hydrogene puisse etre representee par un processus de remplissage des pores par un pseudo-liquide. Ces travaux s'inscrivent dans un contexte ou la capacite d'adsorption reelle des nanostructures de carbone est sujette a la controverse. En consequence, l'approche experimentale adoptee se distingue par les differentes demarches mises de l'avant pour l'obtention de mesures fiables sur des echantillons de faibles masses ainsi que par son caractere

    This autoethnography withdraws from information accumulated through a 10-year period of daily-weekly-monthly descriptive observation-recording (triangulated- parents & house-helper) of caregiving and rehabilitating of our brain injured son (survivor/care-receiver). We present it as an interactive voice of verbal conversation, thoughts, insights, and interpretations. It is delivered as a series of articulation intra-pulsated with our interrogation of societal-cultural-religious perspectives, norms and biases, and aligns with the CAP (Creative Analytical Practices) method of Ellis. This autoethnography glows from the richness of information which encapsulates the challenges confronting us the aging parent caregivers, the gradual incremental mind mending achievement of our son, and the interactive verbalizations and thoughts, of the caregivers, care-receiver, and other persons. The overwhelming mental and physical pain and struggle of the survivor and the aging caregivers and their sense of celebratory-satisfaction with rehabilitation progress are highlighted. Interpretation and valuation of positive and negative responses of other persons provide a critical matrix to this autoethnography. We intend to inform other caregivers and relevant healthcare professionals through this autoethnography. PMID:25763170

  20. When mothers make sons sexy: maternal effects contribute to the increased sexual attractiveness of extra-pair offspring

    2012-01-01

    Quality differences between offspring sired by the social and by an extra-pair partner are usually assumed to have a genetic basis, reflecting genetic benefits of female extra-pair mate choice. In the zebra finch (Taeniopygia guttata), we identified a colour ornament that is under sexual selection and appears to have a heritable basis. Hence, by engaging in extra-pair copulations with highly ornamented males, females could, in theory, obtain genes for increased offspring attractiveness. Indeed, sons sired by extra-pair partners had larger ornaments, seemingly supporting the genetic benefit hypothesis. Yet, when comparing ornament size of the social and extra-pair partners, there was no difference. Hence, the observed differences most likely had an environmental basis, mediated, for example, via differential maternal investment of resources into the eggs fertilized by extra-pair and social partners. Such maternal effects may (at least partly) be mediated by egg size, which we found to be associated with mean ornament expression in sons. Our results are consistent with the idea that maternal effects can shape sexual selection by altering the genotype–phenotype relationship for ornamentation. They also caution against automatically attributing greater offspring attractiveness or viability to an extra-pair mate's superior genetic quality, as without controlling for differential maternal investment we may significantly overestimate the role of genetic benefits in the evolution of extra-pair mating behaviour.

    Les thrombophlébites cérébrales sont des pathologies rares (1/5000 naissances) mais redoutables. La grossesse et le post-partum en sont des circonstances favorisantes: leur symptomatologie clinique est divertie et variée dominée par les céphalées, les convulsions et les déficits neurologiques mais aucun signes n’est spécifique. L’examen physique est souvent pauvre et prêt à confusion avec de nombreuses autres affections. Le diagnostic de certitude ne peut être que neuroradiologique. L’IRM cérébrale est actuellement la méthode de référence, elle permet la visualisation du thrombus veineux et le suivie de son évolution. Le traitement de ces TPC est essentiellement médical basé sur les anticoagulants. A l’occasion de quatre observations de TPC, du post-partum et d’une revue de la littérature, nous allons mettre le point sur l’importance d’un diagnostic précoce et d’une prise en charge thérapeutique adéquate.

  2. Comportement mecanique des joints boulonnes en composites verre-polyester

    NASA Astrophysics Data System (ADS)

    Vangrimde, Bart

    Glass fibre-reinforced polyester composite materials are being extensively used for general-purpose applications. For highly loaded structures, bolted joints are generally the preferred assembly method. However, bolted joints are usually the weakest link in a structure and they must therefore be designed with care. Specifically, the joint geometry, reinforcement type and lay-up should be chosen on a rational basis, otherwise the assembly may fail prematurely. The present study is concerned with the study of these material parameters. The mechanical response of bolted assemblies is studied for a range of six glass fibre-reinforced polyester laminates with reinforcements and lay-ups that are typical for general-purpose applications. In order to assess how changes in joint width or in joint end distance affect the behaviour of the joint, tests were carried out on three coupon geometries. In accordance with the standard test method ASTM D5961, a single-bolt double lap bolted joint configuration was used for the experimental characterisation. We investigated how the displacement measurement could best be made because currently there is a whole range of approaches in use and it is clear that the measured displacement quantity directly affects the stiffness values. A 3-D finite element model indicated that bolt deformation and fixture deformations affected the measured coupon displacement. The bearing stiffness was reduced by 26% on average when the width was reduced from six to two times the hole diameter. For the assemblies with a width of two times the hole diameter (w/D = 2) the bearing stiffness increased clearly with the tensile modulus of the tested materials. Both the experimental and numerical bearing stiffness values were much lower than those predicted by joint flexibility formulas. Hence, our results indicate that these joint flexibility formulas should be adapted if they are intended to be used for design of general-purpose glass fibre-reinforced polyester structures with bolt-hole clearance. The different material/geometry combinations led to very diverse failure modes and strengths, ranging from catastrophic low strength failures to progressive high strength failures. All the small coupons (w/D = 2; e/D = 3) failed catastrophically by tension. We observed that important characteristics of the bearing response such as damage stress, ultimate strength, failure mode and post-failure behaviour were related to reinforcement types and their stacking sequence.

    Le prémélange de monensin est utilisé fréquemment sur les fermes laitières canadiennes. L’ingrédient actif de ce produit est le monensin sodique. Bien que son utilisation chez les vaches laitières soit sécuritaire, des cas de surdose ont été rapportés à la suite de consommation de niveaux de monensin plus élevés que ceux recommandés. Un suivi hebdomadaire du pourcentage de matières grasses du réservoir de lait de la ferme devrait être fait de routine suite à la livraison d’aliment médicamenteux contenant du monensin pour détecter rapidement les situations de surdose. L’observation d’une baisse soudaine de la consommation volontaire de matière sèche et l’apparition de diarrhée dans un troupeau sont d’autres signes cliniques de surdose de monensin. Une détection rapide de ces cas permettra de corriger la situation. PMID:19721781

    This study examines the relationship between the husband's preference for a son, sex composition of children and risk of anaemia and underweight among married Indian women. Information was collected regarding 29,517 couples having at least one child in the nationally representative 2005-06 National Family Health Survey of India. The exposures were husband's preference for a son and sex composition of children: sons only, daughters only and mixed. Outcome included maternal underweight and moderate/severe anaemia. Husband's preference for a son was not found to be associated with his wife's risk of anaemia or underweight. Sex composition of the children was modestly associated with increased odds of anaemia among women from households with daughters only as compared with those with sons only [AOR: 1.19; 95% CI 1.04, 1.35]. The findings from this population-based study of socio-cultural norms around preference for a son and married Indian women's nutritional status do not support the hypothesis that husband's preference for sons influences the nutritional status of their wives. However, having daughters only is associated with maternal anaemia for reasons that remain to be established.

    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

    I have traced in my deliberations the mutual influence of drive and ego development throughout the male child's dyadic and triadic father relatedness as it proceeds within a changing soma and social surround during the first two decades of life. I have made the effort to conceptualize the normal developmental progression in male personality formation with explicit reference to the fate of the boy's dyadic father relationship as well as his negative Oedipus complex in general. These considerations, restricted as they are in scope and gender, assign to the dyadic father complex a nuclear role in neurosogenesis as well as recognize in it an etiological factor in relation to specific forms of psychopathology throughout the male life cycle.

    This study investigated the development of mother-son relationship quality from ages 5 to 15 in a sample of 265 low-income families. Nonparametric random effects modeling was utilized to uncover distinct and homogeneous developmental trajectories of conflict and warmth; antecedents and outcomes of the trajectory groups also were examined. Four conflict trajectory groups and 3 warmth trajectory groups were identified. Difficult temperament in early childhood discriminated both conflict and warmth trajectory group membership (TGM), and adult relationship quality in early childhood was related to warmth trajectories. In addition, conflict TGM differentiated youth antisocial behavior during adolescence, and warmth trajectories predicted adolescent peer relationship quality and youth moral disengagement. Implications for socialization processes are discussed.

    This study addressed two main questions: (a) Are adolescent sons and daughters exposed to sensitive maternal disclosures after divorce with similar frequency and in similar detail? and (b) Does gender act as a moderator in the association between maternal disclosures and adolescent adjustment difficulties? Forced-choice and open-ended data were collected from 194 adolescents within 2 years after their parents' divorce. Quantitative analyses revealed that although the majority of adolescents experience some level of maternal disclosure, neither frequency nor detail of maternal disclosure differed as a function of adolescent gender. Frequent and detailed maternal disclosures were associated with adolescent adjustment difficulties, primarily psychological distress. Gender did not moderate that significant association. Qualitative analysis shed light on the link between maternal disclosures and adolescent distress, suggested the importance of how disclosures are made, and revealed several gender differences in reactions to maternal disclosures. Implications of the findings are discussed.

Seven couples and 3 mothers were interviewed for the study, and their interviews were analyzed using a phenomenological-hermeneutic approach. Three main themes were extracted from parents' descriptions of their experiences: (a) "From the place where pain and sadness was sown, a new smile was grown," relating to transforming the experience of loss into a new meaning for life; (b) "No to a child memorial," focusing on parents' awareness of the burden placed on the child who was born; and (c) "Different parenting," dealing with participant's parenting following their loss. The study's findings are discussed in the context of literature dealing with reconstructing meaning through coping and bereavement.

    This study investigated the development of mother-son relationship quality from ages 5 to 15 in a sample of 265 low-income families. Non-parametric random effects modeling was utilized to uncover distinct and homogeneous developmental trajectories of conflict and warmth; antecedents and outcomes of the trajectory groups also were examined. Four conflict trajectory groups and three warmth trajectory groups were identified. Difficult temperament in early childhood discriminated both conflict and warmth trajectory group membership (TGM), and adult relationship quality in early childhood was related to warmth trajectories. In addition, conflict TGM differentiated youth antisocial behavior during adolescence, and warmth trajectories predicted adolescent peer relationship quality and youth moral disengagement. Implications for socialization processes are discussed. PMID:21883153

    Sun-as-a-star observations are very important for the study of the conditions within the Sun and in particular for the deep interior where higher degree modes do not penetrate. They are also of significance in this era of dramatic advances in stellar asteroseismology as they are comparable to those measured in other stars by asteroseismic missions such as CoRoT, Kepler, and MOST. More than 17 years of continuous measurements of SoHO and more than 30 years of BiSON observations provide very long data sets of uninterrupted helioseismic observations. In this work, we discuss the present status of all these facilities that continue to provide state-of-the-art measurements and invaluable data to improve our knowledge of the deepest layers of the Sun and its structural changes during the activity cycle.

    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.

    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.

    Purpose To document the HIV testing behaviors and serostatus of younger men of color who have sex with men (YMSM), and to explore sociodemographic, behavioral, and maternal correlates of HIV testing in the past six months. Methods 135 YMSM aged 16–19 completed a close-ended survey on HIV testing and risk behaviors, mother-son communication, and sociodemographic characteristics. Youth were offered point-of-care HIV testing, with results provided at survey end. Multivariate logistic regression analyzed the sociodemographic, behavioral, and maternal factors associated with routine HIV testing. Results 90.3% of YMSM had previously tested for HIV and 70.9 % had tested in the past six months. In total, 11.7% of youth reported being HIV-positive and 3.3% reported unknown serostatus. When offered an HIV test, 97.8% accepted. Of these, 14.7% had a positive oral test result and 31.58% of HIV-positive YMSM (n=6) were seropositive unaware. Logistic regression results indicated that maternal communication about sex with males was positively associated with routine testing (OR=2.36; 95% CI=1.13–4.94). Conversely, communication about puberty and general human sexuality was negatively associated (OR=0.45; 95% CI=0.24–0.86). Condomless anal intercourse and positive STI history were negatively associated with routine testing; however, frequency of alcohol use was positively associated. Conclusions Despite high rates of testing, we found high rates of HIV infection, with 31.58% of HIV-positive YMSM being seropositive unaware. Mother-son communication about sex needs to address same-sex behavior, as this appears to be more important than other topics. YMSM with known risk factors for HIV are not testing at the recommended time intervals. PMID:26321527

    Deletions of the proximal long arm of chromosome 15 result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The minimal critical deletion region for Angelman syndrome has been reported to include D15S74 (B1.5), D15S10 (TD3-21), and D15S113 (LS6-1). We report a mother and son who have deletions that include D15S113 but who do not have features of Angelman syndrome. D.H. is a 10-year-old white male referred for genetic evaluation due to mental retardation. He has mild to moderate mental retardation and minor dysmorphic features, including downslanting palpebral fissures, prominent nose, broad forehead, small chin, midface hypoplasia, and large ears. His mother (B.S.) has slightly downslanting palpebral fissures and a borderline intellectual deficit. Neither individual has the seizures, excessive laughter, hand clapping, ataxia or facial dysmorphism which are characteristic of Angelman syndrome. The linear order of probes mapping to 15q11-q13 is 15cen-D15S11-D15S13-D15S10-D15S113-GABRB3-D15S12-tel. The proximal border of the deletion in our patients lies between D15S10 and D15S113. The fact that these two individuals do not have Angelman syndrome, despite deletion of D15S113, suggests that the Angelman syndrome critical deletion region should be further refined to exclude the D15S113 locus. In addition, the findings of a more severe intellectual impairment in the son than in the mother suggests that the region immediately telomeric to the critical deletion region for Angelman syndrome may contain imprintable genes that influence intellectual function.

    l'agenda politique du pays. Notre projet de recherche, par le truchement de l'approche des reseaux de politique publique, s'attarde a decrire et a expliquer le processus de la formulation d'une politique particuliere, soit la politique energetique a des fins de protection de l'environnement, elaboree en 1993. Il s'agit de mettre en evidence les facteurs affectant le choix des instruments de ces politiques publiques dans leur contexte national. Ainsi, la question generale de cette recherche est: Comment les phases evolutives de la formation d'un reseau de politique, en l'occurrence le Conseil canadien de l'energie (CCE), menent a des caracteristiques particulieres a ce reseau; et comment celles-ci determinent-elles les types des instruments de politique publique choisis, particulierement ceux de la recente orientation des politiques energetiques canadiennes a des fins environnementales elaborees en 1993? Afin d'atteindre l'objectif de notre recherche, deux facteurs primordiaux sont utilises, soit la circulation de l'information et l'exercice du controle sur les ressources des acteurs. L'analyse des caracteristiques du reseau en fonction des liens forts et des liens faibles autant que la presence ou l'absence des trous structuraux nous permettent de bien identifier les positions des differents acteurs, etatiques et non etatiques, sur le plan de l'information et du controle, qui a leur tour, nous semble-t-il, constituent des facteurs affectant les types des instruments des politiques publiques choisis: instruments substantifs, qui indiquent le degre de l'intervention du gouvernement, et instruments proceduraux, qui mettent plutot l'accent sur le degre de l'influence du gouvernement sur les acteurs non etatiques. L'etude soutient que l'approche des reseaux se distingue notamment par son potentiel a expliquer l'interrelation relative entre idees, interets et institutions, ce qui a son tour est susceptible de permettre une meilleure comprehension des processus de l

    Le cancer de l'estomac est représenté essentiellement par Les adénocarcinomes gastriques, ces derniers demeurent l'une des dix premières causes mondiales de mortalité avec un pronostic qui est péjoratif. Son incidence reste variable à travers le monde, elle est caractérisée par une importante disparité géographique. Le but de notre travail est de décrire les caractéristiques épidémiologiques de l'adénocarcinome gastrique dans notre contexte à travers une étude rétrospective, observationnelle étalée sur une période de 10 ans (Janvier 2001- Janvier 2011), incluant tous les malades admis au service d'hépato-gastroentérologie du CHU Hassan II de Fès pour prise en charge d'un adénocarcinome gastrique. Durant cette période, 343 patients étaient admis pour prise en charge d'une tumeur gastrique, dont 170 patients avaient un adénocarcinome gastrique (49.5%). L’âge moyen de ces patients était de 58±13.4 ans [16 ans-0 ans]. Dans 43.7% des cas, les patients provenaient de la région de Fès, souvent du milieu rurale. On note une nette prédominance masculine, avec une différence significative entre les 2 sexes (p < ;0.05). Les patients âgés de moins de 60ans représentaient la tranche d’âge prédominante (63%) par rapports aux patients âgés de plus de 60ans (p = 0.02). 61% des patients consultaient dans un délai allant de 1 mois à 6 mois, 30.4% des patients étaient tabagiques, ce facteur avait une relation statistiquement significative avec l'adénocarcinome gastrique (p = 0.02). la non consommation de l'alcool est inversement liée et de façon significative à l'apparition de l'adénocarcinome gastrique (p = 0.03) dans notre contexte. L'infection par Hélicobacter pylori n’était mentionnée que chez peu de malades. Les formes métastatiques au moment du diagnostic dépassaient 50% avec un taux de décès au cours de l'hospitalisation de 2.6%.

    Dans un contexte constructiviste, les connaissances anterieures d'un individu sont essentielles a la construction de nouvelles connaissances. Quelle qu'en soit la source (certaines de ces connaissances ont ete elaborees en classe, d'autres ont ete elaborees par interaction personnelle de l'individu avec son environnement physique et social), ces connaissances, une fois acquises, constituent les matieres premieres de l'elaboration des nouvelles conceptions de cet individu. Generalement, cette influence est consideree comme positive. Cependant, dans un milieu scolaire ou l'apprentissage de certaines conceptions enchassees dans un programme d'etudes et enterinees par l'ensemble d'une communaute est obligatoire, certaines connaissances anterieures peuvent entraver la construction des conceptions exigees par la communaute. La litterature abonde de tels exemples. Cependant, certaines connaissances anterieures, en soi tout a fait conformes a l'Heritage, peuvent aussi, parce qu'utilisees de facon non pertinente, entraver la construction d'une conception exigee par la communaute. Ici, la litterature nous donne peu d'exemples de ce type, mais nous en fournirons quelques-uns dans le cadre theorique, et ce sera un d'entre eux qui servira de base a nos propos. En effet, une grande proportion d'eleves inscrits a un cours de sciences physiques de la quatrieme secondaire, en reponse a un probleme deja solutionne durant l'annee et redonne lors d'un examen sommatif, "Pourquoi la Lune nous montre-t-elle toujours la meme face?", attribue principalement la cause de ce phenomene a la rotation de la Terre sur son axe. En tant que responsable de l'enseignement de ce programme d'etudes, plusieurs questions nous sont venues a l'esprit, entre autres, comment, dans un contexte constructiviste, est-il possible de reduire chez un eleve, l'impact de cette connaissance anterieure dans l'elaboration de la solution et ainsi prevenir la construction d'une conception erronee?

    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

    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.

    Introduction Le médicament générique est souvent une origine de préjugés négatifs et de méfiance chez les professionnels de santé et les patients. Ceci pourrait être dû à plusieurs facteurs entre autre le manque des connaissances du patient sur ces médicaments. Le but de notre étude était d’évaluer l'information du consommateur sur les médicaments génériques et apprécier leur utilisation de ces médicaments. Méthodes Il s'agit d'une étude transversale réalisée de Janvier à Mars 2010 auprès de 251 sujets. Un questionnaire comprenant dix questions fermées a été utilisé. Les questions concernaient l’évaluation des connaissances sur les médicaments génériques, les sources d'information, le degré de confiance et d'information des patients sur ces médicaments. Une analyse descriptive simple des différentes variables a été réalisée. Résultats Dans notre étude, 126 sujets (50,2%) ont répondu connaître les médicaments génériques. Parmi eux, 52,3% les utilisaient et 67,4% estimaient qu'ils étaient insuffisamment informés sur ces médicaments. Les cadres supérieurs et les étudiants ont représenté la catégorie qui utilisait le plus les médicaments génériques (respectivement dans 40,9% et 25,7%) et qui était la mieux informée (respectivement dans 61,9% et 23,81%). Le faible coût a été la principale motivation d'utilisation du médicament générique (93,9%). Les médias ont représenté la première source d'information (59,5%). Après sensibilisation, 88,8% des sujets qui ne connaissaient pas le médicament générique ont été favorable à son utilisation. Conclusion Une promotion efficace par une politique d'information soutenue auprès des consommateurs et par des mesures incitatrices à la prescription et à la délivrance du générique par les médecins et les pharmaciens, pourront améliorer l'utilisation de ces médicaments dans notre pays.

    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

    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.

  18. How parasitoid females produce sexy sons: a causal link between oviposition preference, dietary lipids and mate choice in Nasonia.

    PubMed

    Blaul, Birgit; Ruther, Joachim

    2011-11-07

    Sexual selection theory predicts that phenotypic traits used to choose a mate should reflect honestly the quality of the sender and thus, are often costly. Physiological costs arise if a signal depends on limited nutritional resources. Hence, the nutritional condition of an organism should determine both its quality as a potential mate and its ability to advertise this quality to the choosing sex. In insects, the quality of the offspring's nutrition is often determined by the ovipositing female. A causal connection, however, between the oviposition decisions of the mother and the mating chances of her offspring has never been shown. Here, we demonstrate that females of the parasitic wasp Nasonia vitripennis prefer those hosts for oviposition that have been experimentally enriched in linoleic acid (LA). We show by (13)C-labelling that LA from the host diet is a precursor of the male sex pheromone. Consequently, males from LA-rich hosts produce and release higher amounts of the pheromone and attract more virgin females than males from LA-poor hosts. Finally, males from LA-rich hosts possess three times as many spermatozoa as those from LA-poor hosts. Hence, females making the right oviposition decisions may increase both the fertility and the sexual attractiveness of their sons.

    Human populations show remarkable variation in the sex ratio at birth which is believed to be related to the parental condition. In the present study, the global variation of sex ratio at birth (SRB, proportion of male offspring born) was analyzed with respect to indirect measure of condition, the intelligence quotient (IQ). IQ correlates strongly with lifespan across nations, which makes it a good indicator of health of the large populations. Relation between three standard measures of average national IQ and SRB was studied using multiple linear regression models. Average national IQ was positively correlated with SRB ( r = 0.54 to 0.57, p < 0.001). Further, IQ emerged as a powerful predictor of SRB after controlling for the effects of all the known covariates like fertility, maternal age, polygyny prevalence, wealth, son preference, latitude, low birth weight, and neonatal mortality in the regression models. These results suggest that the striking variation of offspring sex ratio across nations could be caused in part by the difference in general condition of populations.

    2009-01-01

    Recently, an acoustic current meter known as the OTT * acoustic digital current meter (ADC) was introduced as an alternative instrument for stream gaging measurements. The Bureau of Reclamation and the U.S. Geological Survey collaborated on a side- by-side evaluation of the ADC and a SonTek/YSI acoustic Doppler velocimeter (ADV). Measurements were carried out in a laboratory flume to evaluate the performance characteristics of the ADC under a range of flow and boundary conditions. The flume contained a physical model of a mountain river with a diversion dam and variety of bed materials ranging from smooth mortar to a cobble bed. The instruments were installed on a trolley system that allowed them to be easily moved within the flume while maintaining a consistent probe orientation. More than 50 comparison measurements were made in an effort to verify the manufacturer’s performance specifications and to evaluate potential boundary disturbance for near-bed and vertical boundary measurements. Data and results from this evaluation are presented and discussed. 

  1. How parasitoid females produce sexy sons: a causal link between oviposition preference, dietary lipids and mate choice in Nasonia

    Sexual selection theory predicts that phenotypic traits used to choose a mate should reflect honestly the quality of the sender and thus, are often costly. Physiological costs arise if a signal depends on limited nutritional resources. Hence, the nutritional condition of an organism should determine both its quality as a potential mate and its ability to advertise this quality to the choosing sex. In insects, the quality of the offspring's nutrition is often determined by the ovipositing female. A causal connection, however, between the oviposition decisions of the mother and the mating chances of her offspring has never been shown. Here, we demonstrate that females of the parasitic wasp Nasonia vitripennis prefer those hosts for oviposition that have been experimentally enriched in linoleic acid (LA). We show by 13C-labelling that LA from the host diet is a precursor of the male sex pheromone. Consequently, males from LA-rich hosts produce and release higher amounts of the pheromone and attract more virgin females than males from LA-poor hosts. Finally, males from LA-rich hosts possess three times as many spermatozoa as those from LA-poor hosts. Hence, females making the right oviposition decisions may increase both the fertility and the sexual attractiveness of their sons. PMID:21429922

  2. "Now if you have only sons you are dead": migration, gender, and family economy in twentieth century northwestern Ghana.

    2011-01-01

    This article explores the interconnectedness between labor migration, gender, and the family economy in northwestern Ghana in the 20th century. It focuses specifically on the Dagaaba of the Nadowli and Jirapa administrative districts of what is now the Upper West Region (UWR). It examines how the relationships between men and women in terms of roles, status, access to productive resources and inheritance, changed in tandem with broader changes in society in the 20th century; changes that over time produced enhanced value and elevated status for women in the family. These changes in gender relations are reflected increasingly in the belief among elderly men that ‘now if you have only sons, you are dead’. By focusing on the lived experiences of ordinary women and men in the migration process, it argues that even though indigenous social structures privileged men over women in almost all spheres of life, Dagaaba women were nonetheless significantly active in shaping the history of their communities and that gender relations in Dagaaba communities were not static — they changed over time and generation. This article contributes to the ongoing discussion of the internal migration phenomenon in West Africa, which has so far attracted scant historical analysis.

    Understanding how axon guidance receptors are activated by their extracellular ligands to regulate growth cone motility is critical to learning how proper wiring is established during development. Roundabout (Robo) is one such guidance receptor that mediates repulsion from its ligand Slit in both invertebrates and vertebrates. Here we show that endocytic trafficking of the Robo receptor in response to Slit-binding is necessary for its repulsive signaling output. Dose-dependent genetic interactions and in vitro Robo activation assays support a role for Clathrin-dependent endocytosis, and entry into both the early and late endosomes as positive regulators of Slit-Robo signaling. We identify two conserved motifs in Robo's cytoplasmic domain that are required for its Clathrin-dependent endocytosis and activation in vitro; gain of function and genetic rescue experiments provide strong evidence that these trafficking events are required for Robo repulsive guidance activity in vivo. Our data support a model in which Robo's ligand-dependent internalization from the cell surface to the late endosome is essential for receptor activation and proper repulsive guidance at the midline by allowing recruitment of the downstream effector Son of Sevenless in a spatially constrained endocytic trafficking compartment.

    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.

    Female coalitions are an important part of the social organization of bonobos. The strength of the mother-son relationship is another essential part of this social structure. A bonobo mother is therefore facing a dilemma when a conflict arises between her sons and her female coalition partners. Will she take her coalition partner's side and favour the social organization of the group or support her son in order to defend her offspring? In order to address this issue, we performed an observational study of the captive group at Planckendael (Belgium) and used social grooming and proximity to assess the relationship between individuals. As a case study, we focused on the relationships between Hortense, one of the group's mothers, her 3 sons Redi, Vifijo and Zamba, and her coalition partner Hermien. Surprisingly, we observed that Hortense preferentially supported her female coalition partner. For Hortense's social status in the group, it may be more important to maintain the strong relationship with her higher-ranking female coalition partner than to support her sons.

    The overall understanding of the molecular etiologies of intellectual disability (ID) and developmental delay (DD) is increasing as next-generation sequencing technologies identify genetic variants in individuals with such disorders. However, detailed analyses conclusively confirming these variants, as well as the underlying molecular mechanisms explaining the diseases, are often lacking. Here, we report on an ID syndrome caused by de novo heterozygous loss-of-function (LoF) mutations in SON. The syndrome is characterized by ID and/or DD, malformations of the cerebral cortex, epilepsy, vision problems, musculoskeletal abnormalities, and congenital malformations. Knockdown of son in zebrafish resulted in severe malformation of the spine, brain, and eyes. Importantly, analyses of RNA from affected individuals revealed that genes critical for neuronal migration and cortex organization (TUBG1, FLNA, PNKP, WDR62, PSMD3, and HDAC6) and metabolism (PCK2, PFKL, IDH2, ACY1, and ADA) are significantly downregulated because of the accumulation of mis-spliced transcripts resulting from erroneous SON-mediated RNA splicing. Our data highlight SON as a master regulator governing neurodevelopment and demonstrate the importance of SON-mediated RNA splicing in human development.

    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.

    Currently, nuclear wastes are commonly immobilized into glasses because of their long-term durability. Exposure to water for long periods of time, however, will eventually corrode the waste form and is the leading potential avenue for radionuclide release into the environment. Because such slow processes cannot be experimentally tested, the prediction of release requires a thorough understanding the mechanisms governing glass corrosion. In addition, due to the exceptional durability of glass, much of the testing must be performed on high-surface-area powders. A technique that can provide accurate compositional profiles with very precise depth resolution for non-flat samples would be a major benefit to the field. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) depth profiling is an excellent tool that has long been used to examine corrosion layers of glass. The roughness of the buried corrosion layers, however, causes the corresponding SIMS depth profiles to exhibit erroneously wide interfaces. In this study, NanoSIMS was used to image the cross-section of the corrosion layers of a leached SON68 glass sample. A wedged crater was prepared by a focused ion beam (FIB) instrument to obtain a 5× improvement in depth resolution for NanoSIMS measurements. This increase in resolution allowed us to confirm that the breakdown of the silica glass network is further from the pristine glass than a second dissolution front for boron, another glass former. The existence of these two distinct interfaces, separated by only ~20 nm distance in depth, was not apparent by traditional ToF-SIMS depth profiling but has been confirmed also by atom probe tomography. This novel sample geometry will be a major benefit to efficient NanoSIMS sampling of irregular interfaces at the nanometer scale that would otherwise be obscured within ToF-SIMS depth profiles.

  11. Mutation rate estimates for 110 Y-chromosome STRs combining population and father–son pair data

    Y-chromosome microsatellites (Y-STRs) are typically used for kinship analysis and forensic identification, as well as for inferences on population history and evolution. All applications would greatly benefit from reliable locus-specific mutation rates, to improve forensic probability calculations and interpretations of diversity data. However, estimates of mutation rate from father–son transmissions are available for few loci and have large confidence intervals, because of the small number of meiosis usually observed. By contrast, population data exist for many more Y-STRs, holding unused information about their mutation rates. To incorporate single locus diversity information into Y-STR mutation rate estimation, we performed a meta-analysis using pedigree data for 80 loci and individual haplotypes for 110 loci, from 29 and 93 published studies, respectively. By means of logistic regression we found that relative genetic diversity, motif size and repeat structure explain the variance of observed rates of mutations from meiosis. This model allowed us to predict locus-specific mutation rates (mean predicted mutation rate 2.12 × 10−3, SD=1.58 × 10−3), including estimates for 30 loci lacking meiosis observations and 41 with a previous estimate of zero. These estimates are more accurate than meiosis-based estimates when a small number of meiosis is available. We argue that our methodological approach, by taking into account locus diversity, could be also adapted to estimate population or lineage-specific mutation rates. Such adjusted estimates would represent valuable information for selecting the most reliable markers for a wide range of applications. PMID:20823913

    2014-01-01

    Background Transthyretin-associated Familial Amyloid Polyneuropathy (TTR-FAP) is an autosomal dominant disease caused by the deposition of abnormal transthyretin that results from a gene mutation. Although rare worldwide, there are descriptions of several endemic foci, such as in Majorca, Balearic Islands, Spain. We aimed at describing a contemporary series of TTR-FAP patients in Son Llàtzer Hospital in Majorca from an epidemiological point of view in order to report their main clinical and laboratory characteristics. Methods A retrospective, observational study was performed. Medical records from adult patients diagnosed with TTR-FAP from a single hospital were reviewed. Results Out of a total of 107 cases, 75 subjects were included: asymptomatic carriers (52.3%) and symptomatic patients (47.7%). Mean age was 58.3 years at the time of the study, and 50.7% were men. Mean age at diagnosis was 49.8 years. In addition, 42 patients (39.2%) had received a liver transplant, and time to liver transplantation was on average 29.56 months from the initial diagnosis. They all had the Val30Met mutation. The organs of the nervous system were those most frequently impaired (57.3%), and 83.9% of the symptomatic patients were fully ambulant (stage 1). Family history was reported in 69.3% of the cases, with the patient’s father being the most commonly affected relative. Comorbidities were frequent, with high blood pressure being the most common. Conclusions Our findings provide additional information on this condition and are useful for describing the demographic features, clinical presentation, diagnosis, and natural course of TTR-FAP in Majorca.

    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.

Cette étude se propose de décrire les résultats d'hémogramme chez les hypertendus et d'identifier les pathologies associées. Méthodes Il s'agit d'une étude rétrospective type descriptif s’étalant du 01 Décembre 2012 au 31 Décembre 2013 au laboratoire du Centre Hospitalo-Universitaire Hôpital Joseph Raseta Befelatanana (CHU-HJRB) d'Antananarivo. Tous les registres des résultats des hypertendus demandant un hémogramme ont été exploités. Résultats Parmi les 151 hypertendus, 91 (60,3%) ont présenté des hémogrammes pathologiques. Parmi ces derniers, 64 (70,4%) ont montré un seul type d'anomalie et 27 (29,6%) des anomalies multiples. Les anémies (33,91%), les hyperleucocytoses (33,04%), les polyglobulies (10,43%) et les leucopénies (9,57%) sont les plus fréquentes. Pour les anomalies multiples, les anémies associées aux hyperleucocytoses sont les plus observées (29,6%). Les anémies microcytaires (41%) et les hyperleucocytoses à polynucléaires neutrophiles sont les plus dominantes (47,4%). Les patients hospitalisés en néphrologie (90%) et en endocrinologie (81,3%) sont les plus concernés (p = 0,008). Les hypertendus moins de 20 ans (100%) et les femmes (61,5%) sont les plus affectés (p > 0,05). Les crises convulsives (100%), les œdèmes des membres inférieurs (100%) et le diabète (70%) sont les signes et pathologies associés les plus rencontrés (p > 0,05). Conclusion L'hémogramme doit être prescrit chez tout patient hypertendu pour connaître les affections sous-jacentes qui seront traitées simultanément avec l'HTA. Ainsi, le patient hypertendu sera pris en charge convenablement et son espérance de vie sera améliorée. PMID:27217875

    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

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

    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.

    Cri du chat syndrome is an autosomal disorder. 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.

    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

    Although underground nuclear waste repositories are not expected to be favourable places for microbial activity, one should not exclude localized action of extremophilic bacteria on some materials involved in the storage concept. Among endogenous or accidentally introduced acidophiles, some are susceptible to lead to a locally drastic decreased in pH, with potential consequences on materials corrosion. Experiments were performed with Acidithiobacillus thiooxidans on 100-125 m french reference nuclear glass SON68 grains in a mineral medium under static conditions during 60 days at 25degC. Growth medium was periodically renewed and analyzed by ICP-AES and ICP-MS spectrometry for both major, trace and ultra-trace elements. Biofilm formation was evidenced by confocal laser microscopy, staining DNA with ethidium bromide and exopolysaccharides with calcofluor white. Biofilm thickness around material grains exceeded 20 m under the chosen experimental conditions. It can be noticed that while numerous studies on biofilm formation upon interaction between Acidithiobacillus ferrooxidans and materials are found in the literature, evidence for biofilm formation is still scarce for the case of the acidophilic bacterium A. thiooxidans. Presence of biofilm is a key parameter for material alteration at the solid/solution interface in biotic systems. Indeed, various constitutive elements of materials trapped in the polyanionic polymer of biofilm may also influence the alteration process. In particular, biofilm may reduce the alteration rate of materials by forming a protective barrier at their surface (Aouad et al., 2008). In this study, glass alteration rates, determined using strontium as tracer, showed that the progressive formation of a biofilm on the surface of glass has a protective effect against its alteration. Uranium and rare earth elements (REE) are efficiently trapped in the biogenic compartment of the system (exopolysaccharides + bacterial cells). Besides, the ratio

    We report on the deployment of two new Son-O-Mermaid floats into theSargasso Sea during a cruise aboard the R/V Atlantic Explorer, whichdeparted from Bermuda in May of 2015. Son-O-Mermaid is a freelyfloating and autonomous oceangoing system composed of a surface buoyconnected to a length of cable from which a three-hydrophone array issuspended. The main objective of the Son-O-Mermaid project is torecord signals suitable for global tomography in the deep ocean andprovide the seismic community with an abundance of novel raypaths frompreviously unsampled regions of the Earth. The Son-O-Mermaid float,with its ability to continually record, analyze, and transmit seismicdata from the oceans in near-real time has the potential torevolutionize the field of seismology. We analyze new data returnedfrom this deployment, a previous Son-O-Mermaid test, as well as theongoing MERMAID mission in the time, spectral, and wavelet domains. Afull description of the float and deployment report will be presented.A short-term goal of the project is determining realistic magnitude,distance, and pressure relationships for teleseismic earthquakes thatare recorded in the water column. Our analysis of this question isaided by synthetics created using SPECFEM2D and guided by the data,especially noise records recorded by Son-O-Mermaid and MERMAID fromoceans throughout the world. Synthetics provide an idealized waveformuseful for understanding the often very messy and noisy arrivalscommon in midcolumn acoustic recordings. Notably, synthetics allowthe confirmation or rejection of unlikely phases which are matched toearthquake databases after arrivals are detected by automatic pickingalgorithms. Additionally, marine-acoustic processing techniques willbe improved once the underwater acoustic field is better modeled usingrealistic signal-to-noise ratios and noise spectra returned fromSon-O-Mermaid and MERMAID missions. This analysis, particularly whenimplemented in the wavelet domain, is proving

    Latinos suffer a disproportionate burden of human papillomavirus (HPV)-preventable cancers, yet uptake and completion of the HPV vaccine among Latinos is below recommendations. Reasons for low HPV vaccine uptake among Latinos in Utah are unknown. We surveyed Latino parents of HPV vaccine age-eligible adolescents (N=118). Univariable analyses identified sociodemographic characteristics associated with HPV vaccine awareness, interest, and uptake for daughter(s) and/or son(s) using chi-square tests or Fisher's exact tests. More parents who had lived in the USA for 15 years or more had vaccinated their daughter (43.6 vs. 32.5%, p=0.035) compared to those living in the USA for shorter time periods. Parents born in Mexico reported their son had not received the HPV vaccine (74.6 vs. 58.3%, p=0.049) more than those born elsewhere. Parents with Mexican birthplace and ancestry reported not knowing about the HPV vaccine as the main barrier to vaccinating daughters (47.1 vs. 5.9%, p=0.002 for both) and sons (birthplace 38.3 vs. 10.3%, p=0.007; ancestry 37.1 vs. 11.1%, p=0.013) compared to those born or descending elsewhere. Non-acculturated parents with a son were more likely to report not knowing about the HPV vaccine as the main barrier to vaccine receipt (47.6 vs. 12.5%, p<0.001). Our results focus on Latinos in an understudied region and complement prior research in other regions. This study may have implications for designing culturally tailored interventions to improve uptake of the HPV vaccine among the growing population of Latinos in Utah, and other states in the Intermountain West.

    Introduction L'objectif de ce travail est de déterminer les fréquences alléliques et génotypiques des sites polymorphes situés dans le gène de l'apolipoprotéine E (apo E) ainsi que leur impact sur les paramètres cliniques et lipidiques dans un échantillon de la population du nord du Maroc cliniquement diagnostiqué ADH. 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

    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.

    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.

    1978-03-01

    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

    le BrdU au niveau cellulaire. Notre hypothese (basee sur des resultats preliminaires effectues dans notre laboratoire) est que l'irradiation de l'ADN cellulaire en presence de BrdU augmentera le nombre de bris simple brin sans toutefois augmenter le nombre de bris double brin. Les resultats presentes dans ce memoire semblent corroborer cette hypothese. Les nouvelles methodes d'analyse, soient l'essai comete et la detection des foci gamma-H2AX remettent en question ce qui a ete dit sur le BrdU au sujet de l'induction des cassures double brin depuis plusieurs annees. L'ensemble de ces nouveaux resultats effectue a l'aide de cellules ayant incorporees du BrdU sont en correlation avec de precedents resultats obtenus dans notre laboratoire sur des oligonucleotides bromes. Ils reaffirment que l'irradiation combinee au BrdU augmente l'induction de bris simple brin mais pas de bris double brin. L'investigation approfondie des mecanismes d'action non elucides du BrdU au niveau cellulaire et son utilisation a des moments strategiques pendant le traitement de radiotherapie pourraient accroitre son efficacite a des fins d'utilisation clinique.

    Introduction Tout patient ayant une maladie chronique nécessitant des prélèvements sanguins répétés ou des traitements par voie veineuse ou susceptible d’évoluer vers l’insuffisance rénale chronique, doit bénéficier d’une stratégie de préservation de son réseau veineux. Le but de ce travail etait de déterminer le rôle de l’infirmier dans la protection du réseau veineux superficiel. Méthodes Etude transversale réalisée au mois d’Avril 2010 à l’hôpital Ibn Sina de Rabat ayant intéressée les infirmiers exerçant dans différents services prenant en charge des patients ayant des pathologies rénales chroniques ou une maladie générale susceptible de se compliquer d’atteinte rénale. Résultats Parmi les 80 infirmiers sollicités, 66 ont complété le questionnaire avec un âge moyen de 42,7 ±11ans et un sex-ratio à 0,7. L’ancienneté moyenne en soins était de 227,7 ± 116,7 mois. 37 % des infirmiers n’étaient pas informés sur la préservation du capital veineux. Le membre supérieur droit était ponctionné dans 92,3% des cas. Le site de ponction le plus utilisé était le dos de la main dans 84,6 % des cas. La dilatation des veines par le réchauffement était notée dans 63,3% des cas, par passage d’alcool dans 54,5% des cas et l’emploi du garrot était retrouvé dans 95,5% des cas. Les venojects étaient de 18 gauge dans 18,2 % des cas et de 21 gauge dans 81,8% des cas. Les intranules étaient de 18 gauge dans 78,8% des cas et de 20 gauge dans 21,2 % des cas. Durant les six derniers mois avant l’étude, les complications au niveau du site de ponction étaient notées dans 41 % des cas. Conclusion L’information et l’éducation du personnel paramédical sont obligatoires ainsi que l’utilisation des cathéters veineux de petit calibre afin d’assurer cette protection. PMID:22593793

    La rupture myocardique est une complication rare mais souvent fatale de l'infarctus du myocarde aigu récent. Une patiente âgée de 72 ans, présentant une douleur thoracique typiquement angineuse évoluant depuis 34 jours, en insuffisance cardiaque globale était reçue pour une exploration cardio-vasculaire. L'examen physique retrouvait un souffle holosystolique endapexien d'intensité 3/6, irradiant en rayon de roue. La troponine T était élevée à quatre fois la normale et l'ECG objectivait une lésion sous épicardique en antéroseptoapical et une nécrose dans le même territoire. L’échodoppler cardiaque retrouvait un anévrisme septoapicolatéral avec une solution de continuité dans le segment apical du septum interventriculaire (CIV). Traitée par énoxaparine, antiagrégant plaquettaire, diurétique de l'anse, dérivés morphiniques et oxygène, la patiente présente au deuxième jour de son hospitalisation un collapsus cardio-vasculaire et décède dans un tableau de choc cardiogénique malgré l'administration des amines vasopressives à forte dose. La coronarographie n'a pu être réalisée. Ce cas illustre la gravité des complications mécaniques de l'infarctus du myocarde. L'absence de chirurgie cardiaque dans notre pays explique en grande partie l’évolution fatale de cette CIV ischémique. PMID:25922631

    Le muscle psoas est une localisation exceptionnelle du kyste hydatique. Le but de cette lettre est de rapporter l'observation d'un kyste hydatique localisé au niveau du muscle psoas gauche chez un patient âgé de 32 ans. L'échographie, la tomodensitométrie ainsi qu'une sérologie hydatique positive ont contribué au diagnostic préopératoire. Le patient a été opéré par incision para rectale gauche type Jalaguier. L'examen microscopique du culot de centrifugation du liquide hydatique a mis en évidence des scolex et de nombreux crochets confirmant ainsi le diagnostic. L'évolution était bonne sans récidive après le traitement chirurgical. PMID:28154657

    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.

    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.

    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.

    Sir William Newbigging was a surgeon to the Edinburgh Royal Infirmary from 1802. While a dextrous operator, he was regarded principally as an excellent general practitioner. He was President of the Royal College of Surgeons of Edinburgh 1814-16 and was knighted by Queen Victoria in 1838. He had five sons, four of whom followed him into the medical profession. Four of his sons died young-only Patrick outlived him. When Patrick returned from a Continental tour in 1842 he joined his father's general practice and when Sir William died in 1852 he took it over. From 1861 to 1863 he was also President of the Royal College of Surgeons of Edinburgh. His last few years were plagued by ill health and he died in 1864, shortly after his fiftieth birthday.

    Parents are influential over mate choice, and in most human societies they choose spouses for their offspring according to their own preferences. However, surprising little is known about the qualities which make a woman desirable as a daughter-in-law and a man desirable as a son-in-law. Using evidence from 67 societies such traits are identified and three hypotheses are tested: first, the hypothesis is tested that parents desire in an in-law qualities which are beneficial to them and their kin. Second, it is hypothesized that such preferences are contingent upon the sex of the in-law, as traits are weighted differently in a daughter-in-law and in a son-in-law. The third hypothesis tested is that parental preferences vary according to the subsistence type of a given society, as traits are valued differently in agropastoral societies and foraging societies. The evidence presented here provides support for all three hypotheses.

    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).

    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.

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.

    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.

    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.

    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.

    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.

    Some odorous products as tetrahydrothiophene (THT) whose odour is perceived at low concentration, are injected in natural gas in order to odorize it. This artificial odorization allows to detect immediately any gas leak in atmosphere. The authors have measured the equilibrium compositions of gaseous phases for binaires THT-CH4, THT-N2 and THT-CO2 in the transport and distribution conditions of natural gas [ {1 < P (bar) < 60} and {-30 < t(^circ C) < 50}] . For this purpose an experimental device based on a principle of dynamic saturation coupled with an on-line gas chromatographic analysis was assembled and adjusted. Additional thermodynamic properties are required to know the molar composition of vapour phase. The authors have measured the THT vapour pressure and estimated the second virial coefficients. For the estimations it was necessary to know the critical values and the acentric factor that have been calculated with various correlations. Certains produits comme le tétrahydrothiophène (THT), dont l'odeur est perçue à faible teneur, sont injectés dans le gaz naturel en vue de son odorisation. Cette odorisation artificielle rend toute fuite éventuelle de gaz dans l'atmosphère immédiatement détectable. Les auteurs ont mesuré les compositions à l'équilibre des phases gaseuses des binaires THT-CH4, THT-N02 et THT-CO2 dans les conditions de transport et de distribution du gaz [ {1 < P (bar) < 60} and {-30 < t(^circ C) < 50}] . Dans ce but, un dispositif expérimental original basé sur un principe de saturation dynamique avec analyse chromatographique en ligne de la phase vapeur a été réalisé et mis au point. Des grandeurs thermodynamiques supplémentaires sont nécessaires pour atteindre les compositions molaires de la phase vapeur. Les auteurs ont mesuré les pressions de vapeur du THT et estimé les seconds coefficients du viriel. Ces estimations font intervenir les grandeurs critiques et facteurs acentriques qui ont été calculés par diverses

    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. Tant les hypothèses supplémentaires relatives au procédé et nécessaires au modèle que les résultats finaux sont résumés.

Nous presentons egalement le FHC de covariance (FHCC) et ses derives de phase, lesquels permettent d'accroi tre davantage la capacite de discrimination du FHC dans les cas ou les objets composants la scene sont tres semblables. La performance de chacun des filtres est evaluee au moyen de simulations sur ordinateur avant d'etre mesuree sur un correlateur optique. Le FHC, FHCP, FHCC et FHCCP sont encodes dans un hologramme genere par ordinateur tandis que les filtres binaires sont affiches sur un televiseur a cristaux liquides. Enfin, nous termions ce manuscrit en presentant le FHCB multiplexe qui permet de correler, en une seule operation, un objet et plusieurs FHC de differents ordres.

    Daniel John Cunningham was a son of the manse. His father John (1819-93) was the parish priest at Crieff, Perthshire from 1845 and was to remain there for 41 years. In 1886 he was appointed Principal of St Mary's College of the University of St Andrews and Moderator of the Church of Scotland. Daniel was educated at Crieff Academy before he progressed to the University of Edinburgh. He graduated MB CM with First-class Honours in 1874 and then proceeded MD in 1876 when he was awarded a Gold Medal for his thesis. He acted as Demonstrator to Professor Turner (1832-1916) in Edinburgh for eight years until 1882 and was then appointed to the Chair of Anatomy at the Royal College of Surgeons of Ireland, in Dublin. After only one year there, he transferred to Trinity College, Dublin, where he occupied a similar position for 20 years. In 1903, on the appointment of Sir William Turner to the post of Principal and Vice-Chancellor of the University of Edinburgh, Daniel was invited to succeed him as Professor of Anatomy in Edinburgh. Daniel held this post until his premature death in 1909. He had three sons and two daughters. Each of his three sons achieved distinction in different fields - one in the Army, another in the Navy and the third in the Indian Medical Service. One of Daniel's daughters married Dr Edwin Bramwell (1873-1952), who was later to occupy the Moncrieff Arnott Chair of Clinical Medicine in the University of Edinburgh.

    Ainhum, also known as dactylolysis spontanea, is a painful constriction of the base of the fifth toe, frequently followed by spontaneous amputation a few years later. The disease is often symmetrical on both the feet, but, occasionally, other toes are also affected and rarely the distal phalanx of the fifth finger. Pseudoainhum is a similar condition that occurs as a secondary event resulting from certain hereditary and nonhereditary diseases that lead to annular constriction of digits. We hereby present a case of familial ainhum in father and son with multiple toes affected, autoamputation, and more involvement of fourth toe than the fifth toe, which is a very rare finding.

    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.

    Autism spectrum disorder characteristics have not been evaluated in Cornelia de Lange and Cri du Chat syndromes using robust assessments. The Autism Diagnostic Observation Schedule and Social Communication Questionnaire were administered to 34 participants with Cornelia de Lange syndrome and a comparison group of 23 participants with Cri du Chat syndrome (M ages 12.4 [SD = 3.8] and 10.3 years [SD = 3.6], respectively). Twenty-one participants with Cornelia de Lange syndrome (61.8%) scored above the autism cut-off on the Autism Diagnostic Observation Schedule compared to 9 with Cri du Chat syndrome (39.2%). Prevalence of autism spectrum disorder characteristics is heightened in Cornelia de Lange syndrome. The profile of characteristics is atypical to that of idiopathic autism.

    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.

    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

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

    We discuss many aspects of a reproduction of a formal painting from the XVIth century. It is a portrait of Viceroy of New Spain Luis de Velasco, El Joven or Hijo (son-see text), found at the Museum of the Pecos National Monument (near Pecos and Santa Fe, New Mexico). A formal portrait of each Viceroy of New Spain was created, and this one was painted during de Velasco's first term as Viceroy (1590 to 1595 AD). In this depiction, he is seen wearing spectacles. To our knowledge, this is the first known reference suggesting the introduction of this form of visual correction in the Spanish Colonies in the Americas and in the future United States. There are three known portraits of Luis de Velasco (son): One painting, which included his father and significant others, hangs in the Colegiata (a small cathedral) de San Luis near Valladolid, Spain. In this portrayal, he was shown as a young man without a spectacle correction. And there are two viceregal portraits (Term 1, 1590 to 1595; Term 2, 1607 to 1611) in which he wears the same spectacle correction (these are located in Mexico City).

  3. A new efficient method for determining weighted power spectra: detection of low-frequency solar p-modes by analysis of BiSON data

    We present a new and highly efficient algorithm for computing a power spectrum made from evenly spaced data which combines the noise-reducing advantages of the weighted fit with the computational advantages of the fast Fourier transform. We apply this method to a 10-yr data set of the solar p-mode oscillations obtained by the Birmingham Solar Oscillations Network (BiSON) and thereby uncover three new low-frequency modes. These are the ℓ= 2, n= 5 and n= 7 modes and the ℓ= 3, n=7 mode. In the case of the ℓ= 2, n= 5 mode, this is believed to be the first such identification of this mode in the literature. The statistical weights needed for the method are derived from a combination of the real data and a sophisticated simulation of the instrument performance. Variations in the weights are due mainly to the differences in the noise characteristics of the various BiSON instruments, the change in those characteristics over time and the changing line-of-sight velocity between the stations and the Sun. It should be noted that a weighted data set will have a more time-dependent signal than an unweighted set and that, consequently, its frequency spectrum will be more susceptible to aliasing.

    In this study, 156 participants, predominantly White British adults (M age = 44.3 years) rated themselves on overall IQ and on H. Gardner's (1983) 7 intelligence subtypes. Parents (n = 120) also estimated the intelligence of their children. Men's self-estimates were significantly higher than women's (110.15 vs. 104.84). Participants thought their verbal, mathematical, and spatial intelligence scores were the best indicators of their own overall intelligence. Parents estimated that their sons had significantly higher IQs than their daughters (115.21 vs. 107.49). Self-estimates and estimates of children's multiple intelligences were higher for men and sons, significantly so for logical-mathematical and spatial intelligence. Parents rated 2nd-born daughters as having significantly higher verbal and musical intelligence than their male counterparts. Higher parental IQ self-estimates corresponded with higher IQ estimates for children. Results for 1st-born children were clearest and showed the most significant differences. The findings are interpreted in terms of sociocultural and familial influences and the possibility of actual sex differences in particular abilities.

    The experiences of Irish sons and daughters born into heterosexually-organised parental partnerships/unions whose parents have separated and one has come out as Lesbian, Gay or Bisexual (LGB) were explored through a grounded theory approach. 15 adult children (over the age of 18 years), who varied in age when their parents separated and one disclosed as LGB, were interviewed. The primary concern that emerged centred on participants having to adjust to their parents' being separated, as opposed to their parent being LGB. This involved engaging with the tension that arose from the loss of the parental union, which involved changes to the home environment and adapting to new parental partners and family units. Heightened reflection on sexual orientation and an increased sensitivity to societal LGB prejudice were specifically associated with a parent coming out as LGB. How parents negotiated disclosing the changes to others, the level of support available to parents, and how capable parents were at maintaining the parent-child relationship had an impact on the tension experienced by sons and daughters. Participants moved from initially avoiding and resisting the family changes that were occurring to gradual consonance with their altered family environments. Concluding directions for research and clinical considerations are suggested.

    Deletions of 15q11-q13 typically result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The critical deletion region for Angelman syndrome has recently been restricted by a report of an Angelman syndrome patient with a deletion spanning less than 200 kb around the D15S113 locus. We report here on a mother and son with a deletion of chromosome 15 that includes the D15S113 locus. The son has mild to moderate mental retardation and minor anomalies, while the mother has a borderline intellectual deficit and slightly downslanting palpebral fissures. Neither patient has the seizures, excessive laughter and hand clapping, ataxia or the facial anomalies which are characteristic of Angelman syndrome. The proximal boundary of the deletion in our patients lies between the D15S10 and The D15S113 loci. Our patients do not have Angelman syndrome, despite the deletion of the D15S113 marker. This suggests that the Angelman syndrome critical deletion region is now defined as the overlap between the deletion found in the previously reported Angelman syndrome patient and the region that is intact in our patients. 28 refs., 6 figs.

    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.

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.

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.

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).

    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. Enfin, avec l'acide chlorhydrique, la surface du mortier est recouverte de chlorure de calcium dihydrate et d'hydroxyde de fer. Les résistances mécaniques sont plus ou moins affectées par la concentration mais aussi et surtout par la nature des acides avec dans l'ordre le plus agressif H{2}SO{4} puis HCl et CH{3}COOH enfin peu de modification pour H{3}PO{4}.

    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

    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.

    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.

    Introduction Le faible poids de naissance constitue un problème majeur de santé publique, aussi bien dans les pays développés que dans les pays en développement, de par son ampleur et sa forte association avec la morbidité et la mortalité infantiles. Méthodes Il s’agit d’une étude cas-témoins rétrospective menée sur les différents facteurs de risque de faible poids de naissance(FPN) en milieu semi-rural de Kamina chez les accouchées et leurs nouveau-nés respectifs enregistrés de la période allant de janvier 2009 à décembre 2010. Résultats Cette étude a répertorié 69 cas des nouveau-nés de FPN sur 483 accouchements enregistrés (14,3%). Les facteurs associés au FPN déterminés dans ce travail sont l’âge maternel inférieur à 18 ans (OR=7,62, IC=3.46-16.8) et supérieur à 35 ans (OR=2,04;IC=0.91-4.46), la primiparité(OR=2,48;IC=1.18-5.21) et le non suivi des consultations prénatales (OR=5,50;IC=2.00-15.03), la prématurité avec grossesse âgée de moins de 37 semaines d’aménorrhée, la grossesse multiple (OR=30,94) et le sexe féminin du nouveau-né. Conclusion Cette étude a démontré que l’âge maternel inférieur à 18 ans et supérieur à 35 ans, le non suivi des consultations prénatales, la primiparité et la prématurité, la grossesse multiple et le sexe féminin du nouveau-né sont les facteurs associés au faible poids de naissance.

    Certain aspects of the use of the Snijders-Oomen Non-verbal Intelligence Test (SON-R 6-40) in clinical and educational assessment of children with hearing impairment and children from immigrant families are discussed. Test results of 35 children per group have been compared to the data from a German-speaking control group, matched by age, sex and educational achievement of both parents. Specific differences between the three groups on both subtest and IQ levels are demonstrated. This paper provides scoring results for the three groups and discusses the differences between the test profiles. The test can be accomplished with children who have special educational needs. Results also prove the usefulness of a non verbal test in the assessment of cognitive abilities in clinical-diagnostic questions.

  18. Oculofacialbulbar palsy in mother and son: review of 26 reports of familial transmission within the 'Möbius spectrum of defects'.

    We report a mother and son with 5th, 6th, 7th, and bulbar cranial nerve paralysis, who had two similarly affected relatives. None of them had primary skeletal defects. Twenty-six previous reports of familial cases within the heterogeneous 'Möbius spectrum of defects' were reviewed. When cranial nerve palsies were associated with a primary skeletal defect, familial transmission was not found. No recurrence was noted in 31 cases with cranial nerve palsies associated with oral abnormalities and limb defects. The term Möbius syndrome should be restricted to cases with congenital 6th and 7th nerve paralysis with skeletal defects, who have a low recurrence risk (2%). The features in an index case which may indicate a higher risk of recurrence are the absence of skeletal defects, isolated facial palsy, deafness, ophthalmoplegia, and digital contractures. A recurrence risk of 25 to 30% in these cases appears reasonable. Images PMID:1999828

    The grandfather-father-son relationship of the first three lords of the Date clan in Japan was ascertained by HLA-DNA sequencing analysis. From their hairs and dried lung tissue found in ca. 300-year-old remains, DNA was extracted with usual phenol-chloroform method followed by purification with cetyltrimethylammonium bromide (CTAB). Two HLA class II genes, HLA-DQA1 and -DPB1, were amplified by seminested, or dual/triple PCR. The PCR products were cloned and analyzed by automated sequencing. Since the three lords shared a haplotype of DQA1*0301-DPB1*0402, we concluded that there is no inconsistency in their lineage. This is the first case of biological evidence for a historical Samurai family relationship in the 17-18th centuries.
