The establishment of two novel bovine cell lines by transfection with the putative transforming region of bovine adenovirus type 3

Human adenoviruses (Ads), members of the family adenoviridae, are medium-sized DNA viruses which have been used as valuable research tools for the study of RNA processing, oncogenic transformation, and for the development of viral vectors for use in gene delivery and immunization technology. The left 12% of the linear Ad genollle codes for products which are necessary for the efficient replication of the virus, as well as being responsible for the forlllation of tumors in animallllodels. The establishlllent of the 293 cell line, by immortalization of human embryonic kidney cells with th~ E1 region of Ad type S (AdS), has facilitated extensive manipulation of the Ads and the development of recombinant Ad vectors. The study of bovine adenoviruses (BAVs), which cause mild respiratory and gastrointestinal infections in cattle has, on the other hand, been limited primarily to that of infectivity, immunology and clinicallllanifestations. As a result, any potential as gene delivery vehicles has not yet been realized. Continued research into the molecular biolo~gy of BAVs and the development of recolllbinant vectors would benefit from the development of a cell line analogous to that of the 293 cells. In an attelllpt to establish such a cell line, the recombinant plaslllid pKC-neo was constructed, containing the left 0-19.7% of the BAV type 3 (BAV3) genome, and the selectable marker for resistance to the aminoglycoside G418, a neomycin derivative. The plasmid construct was then used to transfect both the Madin-Darby bovine kidney (MDBK) -iicell line and primary bovine lung cells, after which G418-resistant foci were selected for analysis. Two cell lines, E61 (MDBK) and E24 (primary lung), were subsequently selected and analysed for DNA content, revealing the presence of the pKC-neo sequences in their respective genomes. In addition, BAV3 RNA transcripts were detected in the E61 cells. Although the presence of E1 products has yet to be confirmed in both cell lines, the E24 cells exhibit a phenotype characteristic of partial transformation by E1. The apparent immortalization of the primary lung cells will permit exploitation of their ability to take up exogenous DNA at high efficiency.

The nature of avidyÄ in Buddhism and VedÄ nta

This thesis deals with the nature of ignorance as it was interpreted in the Upani~adic tradition, specifically in Advaita Vedanta, and in early and Mahayana Buddhism , e specially in the Madhyamika school of Buddhism. The approach i s a historical and comparative one. It examines the early thoughts of both the upanis.a ds and Buddhism abou t avidya (ignorance), shows how the notion was treated by the more speculative and philosphically oriented schools which base d themselves on the e arly works, and sees how their views differ. The thesis will show that the Vedinta tended to treat avidya as a topic for metaphysical s peculation as t he s chool developed, drifting from its initial e xistential concerns, while the Madhyamika remained in contact with the e xistential concerns evident in the first discourses of the Buddha. The word "notion" has been chosen for use in referring t o avidya, even though it may have non-intellectual and emotional connotations, to avoid more popular a lternatives such as "concept" or "idea". In neither the Upani,ads, Advaita Vedanta, or Buddhism is ignorance merely a concept or an idea. Only in a secondary sense, in texts and speech , does it become one. Avidya has more to do with the lived situation in which man finds himself, with the subjectobject separation in which he f eels he exists, than with i i i intel lect ual constr ucts . Western thought has begun to r ealize the same with concerns such as being in modern ontology, and has chosen to speak about i t i n terms of the question of being . Avidya, however, i s not a 'question' . If q ue stions we r e to be put regarding the nature of a vidya , they would be more of t he sort "What is not avidya?", though e ven here l anguage bestows a status t o i t which avidya does not have. In considering a work of the Eastern tradition, we f ace t he danger of imposing Western concepts on it. Granted t hat avidya is customari ly r endered i n English as ignorance, the ways i n which the East and West view i gno rance di f f er. Pedagogically , the European cultures, grounded in the ancient Greek culture, view ignorance as a l ack or an emptiness. A child is i gnorant o f certain t hings and the purpose o f f ormal education , in f act if not in theory, is to fill him with enough knowledge so that he can cope wit h t he complexities and the e xpectations of s ociety. On another level, we feel t hat study and research will l ead t o the discovery o f solutions, which we now lack , for problems now defying solut i on . The East, on the o t her hand, sees avidya in a d i fferent light.Ignorance isn't a lack, but a presence. Religious and philosophical l iterature directs its efforts not towards acquiring something new, but at removing t.he ideas and opinions that individuals have formed about themselves and the world. When that is fully accomplished, say the sages , t hen Wisdom, which has been obscured by those opinions, will present itself. Nothing new has to be learned, t hough we do have t o 'learn' that much. The growing interest in t he West with Eastern religions and philosophies may, in time, influence our theoretical and practical approaches to education and learning, not only in the established educati onal institutions, but in religious , p sychological, and spiritual activities as well. However, the requirements o f this thesis do no t permit a formulation of revolutionary method or a call to action. It focuses instead on the textual arguments which attempt to convince readers that t he world in which they take themselves to exist is not, in essence, real, on the ways i n which the l imitations of language are disclosed, and on the provisional and limited schemes that are built up to help students see through their ignorance. The metaphysic s are provisional because they act only as spurs and guides. Both the Upanisadic and Buddhist traditions that will be dealt with here stress that language constantly fails to encompass the Real. So even terms s uch as 'the Real', 'Absolute', etc., serve only to lead to a transcendent experience . The sections dealing with the Upanisads and Advaita Vedanta show some of the historical evolution of the notion of avidya, how it was dealt with as maya , and the q uestions that arose as t o its locus. With Gau?apada we see the beginnings of a more abstract treatment of the topic, and , the influence of Buddhism. Though Sankhara' S interest was primarily directed towards constructing a philosophy to help others attain mok~a ( l iberation), he too introduced t echnica l t e rminology not found in the works of his predecessors. His work is impressive , but areas of it are incomplete. Numbers of his followers tried to complete the systematic presentation of his insi ghts . Their work focuses on expl anat i ons of adhyasa (superimposition ) , t he locus and object of ignorance , and the means by which Brahman takes itself to be the jiva and the world. The section on early Buddhism examines avidya in the context o f the four truths, together with dubkha (suffering), the r ole it p l ays in t he chain of dependent c ausation , a nd t he p r oblems that arise with t he doctrine of anatman. With t he doct rines of e arly Buddhism as a base, the Madhyamika elaborated questions that the Buddha had said t e nded not t o edi f ication. One of these had to do with own - being or svabhava. Thi s serves a s a centr e around which a discussion o f i gnorance unfolds, both i ndividual and coll ective ignorance. There follows a treatment of the cessation of ignorance as it is discussed within this school . The final secti on tries to present t he similarities and differences i n the natures o f ignorance i n t he two traditions and discusses the factors responsible for t hem . ACKNOWLEDGEMENTS I would like to thank Dr. Sinha for the time spent II and suggestions made on the section dealing with Sankara and the Advait.a Vedanta oommentators, and Dr. Sprung, who supervised, direoted, corrected and encouraged the thesis as a whole, but especially the section on Madhyamika, and the final comparison.

Keyword Competition and Determinants of Ad Position in Sponsored Search Advertising

Given the significant growth of the Internet in recent years, marketers have been striving for new techniques and strategies to prosper in the online world. Statistically, search engines have been the most dominant channels of Internet marketing in recent years. However, the mechanics of advertising in such a market place has created a challenging environment for marketers to position their ads among their competitors. This study uses a unique cross-sectional dataset of the top 500 Internet retailers in North America and hierarchical multiple regression analysis to empirically investigate the effect of keyword competition on the relationship between ad position and its determinants in the sponsored search market. To this end, the study utilizes the literature in consumer search behavior, keyword auction mechanism design, and search advertising performance as the theoretical foundation. This study is the first of its kind to examine the sponsored search market characteristics in a cross-sectional setting where the level of keyword competition is explicitly captured in terms of the number of Internet retailers competing for similar keywords. Internet retailing provides an appropriate setting for this study given the high-stake battle for market share and intense competition for keywords in the sponsored search market place. The findings of this study indicate that bid values and ad relevancy metrics as well as their interaction affect the position of ads on the search engine result pages (SERPs). These results confirm some of the findings from previous studies that examined sponsored search advertising performance at a keyword level. Furthermore, the study finds that the position of ads for web-only retailers is dependent on bid values and ad relevancy metrics, whereas, multi-channel retailers are more reliant on their bid values. This difference between web-only and multi-channel retailers is also observed in the moderating effect of keyword competition on the relationships between ad position and its key determinants. Specifically, this study finds that keyword competition has significant moderating effects only for multi-channel retailers.

Proposal for Construction of Brock’s Monument, Queenston, newspaper fragment, 1824

Brock’s Monument is owned by Parks Canada and maintained by the Niagara Parks Commission in collaboration with the Friends of Fort George and Niagara National Historic Sites. It is located in Queenston Heights Park atop the Niagara Escarpment. On March 14, 1815, Parliament passed an act to erect a monument to the memory of General Isaac Brock. A design by engineer Francis Hall was selected. He envisioned a 135 ft. tall Tuscan column, made out of stone with a winding staircase inside. By the spring of 1824, work had begun on the monument. In June of that year, the cornerstone was laid and William Lyon Mackenzie was in attendance at the ceremony. It was on October 13th, 1824 (the anniversary of Brock’s death) that 6000 people traveled to Queenston to inter the remains of Brock and Lieutenant-Colonel Macdonell. This was the second burial for both. After 3 years the tower had reached 135 feet, but there was no inscription at the base, the fence around the observation deck had not been installed and there was no statue of Brock. Hall submitted a plan to finish the statue, but he was turned down and a simple ornament was placed where the Brock statue should have been. A massive blast of gunpowder destroyed the monument in 1840. It is alleged that an American sympathizer with the Upper Canada Rebellion set off the blast. Brock and Macdonell’s bodies were reburied in the Hamilton Family Cemetery in Queenston. The present monument was rebuilt in 1853. William Thomas (designer of St. Michael’s Cathedral in Toronto) was the architect. Brock and Macdonell were once again laid to rest in separate vaults at the statue. In 1968, Brock’s Monument was declared a national historical site. In 2005, it was closed to the public due to safety concerns, but it reopened in 2010.

Photograph - Dorothy Rungeling in Car

A photograph of Dorothy Rungeling sitting in a car parked beside a plane. There is a boy in the car next to her, likely her son Barry. According to her story in Air Facts (reprinted in Bozeman Daily Chronicle), this may be the day back in 1948 when she first went up in an airplane, According to the story, she was with her husband and son taking photographs for ads for their car dealership when she was persuaded by her son to take a turn in the airplane.

Profils de prise en charge médicale chez les enfants et adolescents traités par antidépresseurs : effet des mises en garde réglementaires et publications de guides de pratique clinique

Suite aux notifications de cas de comportements suicidaires associés aux antidépresseurs (ADs) chez les jeunes, une mise en garde réglementaire a été émise en mai 2004 au Canada, et deux guides de pratique clinique ont été publiés dans la littérature en novembre 2007. L'objectif de ce mémoire fut d'évaluer l’association entre ces interventions de communication et le suivi médical de la population pédiatrique traitée par ADs au Québec. Une étude de cohorte rétrospective (1998-2008) a été menée chez 4 576 enfants (10-14 ans) et 12 419 adolescents (15-19 ans) membres du régime public d’assurance médicaments du Québec, ayant débuté un traitement par AD. Le suivi médical dans les trois premiers mois de traitement a été mesuré par l’occurrence et la fréquence de visites médicales retrouvées dans les banques de données de la RAMQ. Les facteurs associés à un suivi conforme aux recommandations ont été évalués à partir de modèles de régression logistique multivariés. Seuls 20% des enfants ou adolescents ont eu au moins une visite de suivi à chaque mois, en conformité avec les recommandations. La probabilité de recevoir un suivi médical conforme était plus élevée lorsque le prescripteur initial était un psychiatre. L’occurrence et la fréquence des visites n’ont pas changé après la publication de la mise en garde ou des recommandations. De ce mémoire on conclut que d'autres interventions visant à optimiser le suivi médical devraient être envisagées.

La légalisation de la publicité directe des médicaments d’ordonnance

La publicité directe des médicaments d’ordonnance (PDMO), interdite au Canada, influence la relation tripartite entre l’industrie pharmaceutique, les consommateurs de médicaments d’ordonnance et les professionnels de la santé. L’industrie pharmaceutique, un secteur très lucratif, emploie diverses tactiques publicitaires dont plusieurs sont nuisibles aux consommateurs. Ces derniers sont la cible de la PDMO et interprètent de multiples façons le message publicitaire reçu. Finalement, les professionnels de la santé jouent un rôle crucial entre l’industrie et les consommateurs puisqu’une ordonnance est nécessaire pour se procurer le produit publicisé. L’encadrement normatif visant la PDMO au Canada est de sources variées. La législation mentionne clairement l’interdiction de ce type de publicité, mais Santé Canada tolère tout de même deux usages relatifs à la PDMO : les annonces de rappel de marque et les annonces de recherche d’aide. Cette situation crée de la confusion puisque l’information transmise aux consommateurs est incomplète. Les Américains ont légalisé la PDMO en favorisant son potentiel éducatif. Il est toutefois difficile de constater les effets positifs de cette légalisation sur la santé publique et l’économie américaine. Au Canada, le médicament Viagra a été l’objet de PDMO, lui conférant un succès économique et populaire. Mais cette notoriété fait que les consommateurs associent aisément le produit à la condition qu’il traite, ce qui est contraire aux usages tolérés par Santé Canada. Tous ces éléments renforcent notre position quant à l’importance de maintenir l’interdiction législative de la PDMO et de l’appliquer de manière plus rigoureuse.

Le proxénétisme au féminin : étude sur le rôle des femmes dans le recrutement de prostituées à Montréal

Bien que le rôle des femmes dans le recrutement de prostituées ne soit pas un phénomène nouveau, peu d’études se sont intéressées au sujet. L’intérêt de cette recherche repose d’ailleurs sur le manque de connaissances de cette problématique qui semble pourtant bien présente dans la société québécoise contemporaine. À l’aide d’entrevues auprès de 15 intervenants du milieu de la police, des organisations communautaires et des centres jeunesse, nous avons recensé de l’information sur 26 cas de femmes recruteuses. L’analyse de différents critères nous a permis de les classer en trois catégories, soit les partenaires, les entremetteuses et les tenancières. Contrairement aux entremetteuses et aux tenancières, les partenaires entretiennent une relation avec un homme complice. Les partenaires, tout comme les tenancières, ont toutes un passé dans la prostitution, alors que certaines entremetteuses n’ont jamais participé à l’industrie du sexe auparavant. La partenaire joue un rôle dans la gestion et le contrôle des victimes, ce qui n’est généralement pas le cas chez l’entremetteuse. La tenancière détient plusieurs responsabilités concernant la gestion d’au moins un établissement érotique. La majorité des partenaires utilise aussi la violence et les menaces pour contrôler leurs victimes, alors que les tenancières semblent user de techniques plus subtiles pour arriver à leurs fins. Bien que plusieurs motivations puissent pousser les recruteuses à chercher de nouvelles recrues, l’obtention de bénéfices monétaires ou matériels est la seule exprimée pour les trois profils. À quelques exceptions près, chacun des trois profils s’exécute selon un processus de recrutement préétabli. Pour la partenaire, il s’agit de cibler une fille vulnérable, de lui offrir un environnement sécuritaire où demeurer, puis de faire miroiter les éléments positifs à être en relation avec elle. L’étape cruciale est le moment où elle demande une contribution monétaire à la victime, puis l’initie à la prostitution. Le processus de recrutement des entremetteuses est semblable à celui des partenaires à l’exception de l’étape cruciale qui sera de mettre la recrue en contact avec un proxénète masculin ou des membres de gang. Le rôle de l’entremetteuse se termine généralement à ce stade. Pour sa part, la tenancière trouve généralement ses recrues au moyen d’annonces dans les journaux ou sur le Web et par ses contacts avec le crime organisé.

Thema: ADHS im Kindes- und Jugendalter - Behandlungsmethoden und Bedeutung für den Unterricht in der Schule

Hyperaktive, unaufmerksame und unruhige Kinder und Jugendliche gibt es scheinbar fast in jeder Familie und in jeder Klasse. Das „Phänomen des unruhigen Kindes“, auch oft als „Zappelphilipp“ bezeichnet, ist alltäglich und in vielen Medien vertreten. Die Störung und das Medikament Ritalin® sind häufig Gegenstand vieler Sendungen, Filme und Serien im Fernsehen, so in „The Simpsons“, „Desperate Housewives“ oder „Galileo“, „Quarks und Co“ und ähnlichen. Aber auch Unmengen an Literatur wird angeboten von „Ratgeber ADHS. Informationen für Betroffene, Lehrer und Erzieher zu Aufmerksamkeitsdefizit-/ Hyperaktivitätsstörungen“ (DÖPFNER, M. ET AL. 2007b) bis hin zu „Albtraum ADS. Wie Eltern sich helfen können“ ( MÄHLER, B ET AL. 2007). Sowohl die Kinder als auch die Eltern werden damit konfrontiert. Viele glauben daher, hyperaktive und unaufmerksame Kinder zu haben oder welche zu sein. Eine Frage, die bei der Recherche zu dem Thema Hyperaktivität und Mangel an Aufmerksamkeit aufkommt, ist: „Ist ADHS eine moderne Krankheit?“. Die zweite Frage, die der ersten rasch folgt, ist: „Ist ADHS eine Krankheit?“. Der Schwerpunkt dieser wissenschaftlichen Hausarbeit liegt auf den Behandlungsmethoden der ADHS und der Bedeutung für den Unterricht in der Schule. Dabei wird hauptsächlich Bezug auf Kinder und Jugendliche genommen, obwohl auch Erwachsene an dieser Störung leiden. Bei Behandlungsmethoden werden vor allem Medikamente mit Methylphenidat im Vordergrund stehen.

Consecuencias psicosociales en adolescentes en situación de desplazamiento

El desplazamiento forzado en Colombia es una consecuencia del conflicto armado, que afecta el 8% del total de la población, de ésta el 50% son niños y adolescentes. Se han descrito diversas consecuencias de este proceso migratorio, que implican aspectos económicos, sociales y de la salud, especialmente de la salud mental, dado por entidades nosológicas como tal, y respuestas emocionales, que parecen ser más frecuentes. Dichas alteraciones psicológicas, pueden estar alterando el proceso de adaptación (aculturación) de estos sujetos, incrementando el sufrimiento emocional y en los adolescentes además entorpeciendo el proceso de consolidación de la identidad, en el cual es indispensable la identificación con el medio externo y la socialización secundaria, que se realiza en el ámbito escolar. Esta investigación busca determinar los mecanismos psicológicos empleados por los adolescentes en situación de desplazamiento (ASD), dentro del ámbito escolar, para lograr la aculturación. Aspectos metodológicos: participaron 15 ASD y 15 pares receptores, alumnos de IED- Estanislao Zuleta, aplicándose entrevistas a profundidad, transcritas de forma inmediata y analizadas en el programa de análisis cualitativo ATLAS ti, estableciendo categorías y relaciones axiales, que permitieron desarrollar hipótesis y una teoría. Resultados: el proceso migratorio está marcado por alteraciones emocionales, que se incrementan en el lugar de recepción asociado a las consecuencias sociales, económicas y políticas del conflicto armado y el desplazamiento forzado. La discriminación, que no fue generalizada en este estudio, favorece estas alteraciones, entorpeciendo el proceso de aculturación. Conclusiones: la capacidad de resiliencia, que en gran medida depende del entorno, favorece la adaptación, por lo que no todos los ADS tienen procesos erráticos de aculturación al entorno. En los adolescentes que persisten las alteraciones emocionales, el proceso de aculturación se ve entorpecido, favoreciendo la segregación y marginación.

Espondiloartropatias seronegativas y viceversa

Introducción. Las Espondiloartropatias Seronegativas (EAS) son un grupo de enfermedades interrelacionadas que presentan compromiso inflamatorio articular y hallazgos extraarticulares. Por otra parte, las Enfermedades Autoinmunes (EAI) son un síndrome clínico caracterizado por la pérdida de la tolerancia inmune. Se encuentra en ellas activación de células B o T, conllevando a daño tisular en ausencia de cualquier otra causa. No existe evidencia sustancial para considerar las EAS como EAI, pero si pueden ser consideradas como enfermedades autoinflamatorias. Dado que la poliautoinmunidad es una de las más importantes características de las EAI, nuestro propósito fue investigar la relación entre EAS y EAI. Materiales y métodos. 2 grupos fueron analizados. Primero, evaluamos la presencia de EAI en una cohorte de pacientes con EAS (n=148). Segundo, examinamos la presencia de EAS en un grupo bien definido de pacientes con EAI (n=1077), incluyendo artritis reumatoide (AR), lupus eritematosos sistémico (LES) y síndrome de Sjögren (SS) Resultados. En el grupo de EAS, dos pacientes presentaron SS (1.4%) y 5 hipotiroidismo autoinmune (HAI) (3.5%). No se encontraron otras EAI en este grupo. La prevalencia de EAI en EAS fue 4.86%. En el grupo de EAI, 5 pacientes presentaron EAS (0.46%). Conclusión. Este estudio no sugiere relación entre EAS y EAI, reforzando la evidencia a favor de que las EAS corresponden más a enfermedades autoinflamatorias que a EAI
