Étude de tour béta actif dans les modulateurs allostériques du récepteur de la prostaglandine F2alpha

La naissance avant terme constitue un important problème de santé périnatale partout dans le monde. Chaque année près de 15 millions de bébés naissent prématurément. Notre laboratoire s’intéresse depuis une décennie à la conception et le développement de nouvelles classes thérapeutiques (appelés agents tocolytiques) capables d’inhiber les contractions utérines et prolonger le temps de gestation. Due à son implication directe dans le déclanchement des contractions utérines, la prostaglandine F2α (FP) est devenue notre cible de choix. Le PDC 113.824 et aza-glycinyl-proline sont apparus comme des inhibiteurs allostériques puissants du récepteur de la prostaglandine F2α, capables de prolonger la durée de gestation chez les souris. Le travail réalisé au cours de ce mémoire a pour objectif d’étudier le tour β nécessaire pour la reconnaissance sur le récepteur de la prostaglandine F2α. Dans la conception de mime peptidique sélectif efficace et puissant, le repliement β est un élément structural essentiel pour le maintien ou l’amélioration de l’activité du mime peptidique. Les études conformationelles du PDC113.824 et l’aza-glycinyl-proline montrent que les squelettes centraux de ces mimes peptidiques pourraient adopter essentiellement un tour β de type I ou II`, ce qui suggère l’implication des deux types de tours dans l’activité biologique. La synthèse de mimes peptidiques adoptant le tour β de type I et II` est devenue une stratégie logique dans la recherche de nouveaux agents tocolytiques. Au cours de ces études quatre analogues du PDC113.824 ont été synthétisés, un azabicyclo[5.3.0]alkanone et un dipeptide macrocyclique (mimes du tours β de type I) pour étudier l’implication du tour β type I. Par la suite la synthèse de glycinyl-proline et le D-alaninyl-proline (des mimes du tour β du type II`) a été réalisée afin de valider l’implication du tour β type II` dans la reconnaissance sur le récepteur. Nous avons utilisé une stratégie de synthèse efficace pour obtenir les deux analogues (azabicyclo [5.3.0]alkanone et dipeptides macrocycles) à partir d’un intermédiaire commun, en procédant par une cyclisation transannulaire diastéréosélective du tétra-peptide.

The intention to notice : the collection, the tour and ordinary landscapes

The Intention to Notice: the collection, the tour and ordinary landscapes is concerned with how ordinary landscapes and places are enabled and conserved through making itineraries that are framed around the ephemera encountered by chance, and the practices that make possible the endurance of these material traces. Through observing and then examining the material and temporal aspects of a variety of sites/places, the museum and the expanded garden are identified as spaces where the expression of contemporary political, ecological and social attitudes to cultural landscapes can be realised through a curatorial approach to design, to effect minimal intervention. Three notions are proposed to encourage investigation into contemporary cultural landscapes: To traverse slowly to allow space for speculations framed by the topographies and artefacts encountered; to [re]make/[re]write cultural landscapes as discursive landscapes that provoke the intention to notice; and to reveal and conserve the fabric of everyday places. A series of walking, recording and making projects undertaken across a variety of cultural landscapes in remote South Australia, Melbourne, Sydney, London, Los Angeles, Chandigarh, Padova and Istanbul, investigate how communities of practice are facilitated through the invitation to notice and intervene in ordinary landscapes, informed by the theory and practice of postproduction and the reticent auteur. This community of practice approach draws upon chance encounters and it seeks to encourage creative investigation into places. The Intention to Notice is a practice of facilitating that also leads to recording traces and events; large and small, material and immaterial, that encourages both conjecture and archive. Most importantly, there is an open-ended invitation to commit and exchange through design interaction.

Laughing & disability : comedy, collaborative authorship and Down Under Mystery Tour

This thesis is an exploration of representation, authorship and creative collaboration in disability comedy, the centre piece of which is a feature-length film starring, co-created and co-written by three intellectually-disabled people. The film, entitled Down Under Mystery Tour, aims to entertain, and be accessible to, a mainstream audience, one that would not normally care about disability or listen to disabled voices. In the past, the failure of these voices to reach audiences has been blamed on poor training, marginal timeslots and indifferent audiences. But this project seeks an alternative approach, building collaboration between disabled and non-disabled people to express voice, conceive, construct and produce a filmed narrative, and engage willing audiences who want to listen.

Dulux Study Tour for Australian Achievement in Architecture Awards Recipient Report 2008

The Dulux Study Tour is a collaborative initiative between Dulux, the Australian Institute of Architects and EmAGN. Each year five (5) architectural professionals (within 10 years of graduation) are selected to join the Dulux Study Tour, an international tour visiting leading architectural firms, recently completed projects and architecturally rich locations. The Dulux Study Tour acknowledges the contribution the selected emerging architects make to practice, research and the culture of architecture, and seeks to further inspire the next generation of emerging architects.

Pivotal people, pivotal journeys: Interim report on the impact of a fundraising study tour on CEOs and their organisations

A longitudinal qualitative study was conducted with CEOs of 12 fundraising organisations across Australia to answer the question - how mights a change in the CEO's fundraising knowledge improve fundraising activity and outcomes for their organisation? The CEOs along with the inaugural Australian Grantmaker of the Year, Caitriona Fay from Perpetual and lead researcher Dr Wendy Scaife travelled to San Antonio, Texas, USA to attend the annual Association of Fundraising Professionals (AFP) conference in March 2014. Participants identified five main success factors for such group learning initiatives about fundraising: - Getting away from the day to day business of running the organisation - Informal, social time to debrief and get to know others - Diversity of organisations whereby no one was in direct competition to others - Commitment, openness and willingness of individuals to participate - Group facilitation This research has been supported by the Perpetual Foundation – Trustees Endowment, The Edward Corbould Charitable Trust, and the Samuel and Eileen Gluyas Charitable Trust under the management of Perpetual Trustee Company Ltd.
