    Luminescence dating applied to medieval architecture

    Avranches’ keep remains constitute a witness of Anglo-Norman knowledge on castle building. Their similarity with other buildings such as Ivry-la-Bataille castle or London Tower required determining the place of Avranches keep in this group: pioneer or imitation? Therefore, samples of brick for luminescence dating were taken from the remaining little tower. Results indicate a chronology later than assumed: second part of the 12th century and first part of 13th century. These dates tend to prove that north-east tower remains would correspond to a reconstruction phase and not to the original construction.Le donjon d’Avranches reprĂ©sente un des rares tĂ©moins de l’architecture castrale anglo-normande. Son plan prĂ©sente d’importantes resemblance avec d’autres edifices de du mĂȘme contexte chrono-culturel, comme le donjon d’Ivry-la-Bataille ou la Tour de Londres. Ces ressemblances posent la question de la place du donjon d’Avranches dans cet ensemble : s’agit-il d’un Ă©difice prĂ©curseur ou d’une imitation ? C’est pourquoi plusieurs prĂ©lĂšvements de brique ont Ă©tĂ© prĂ©levĂ©s dans les vestiges de ce bĂątiment, afin de procĂ©der Ă  la datation de la sa construction. Les rĂ©sultats semblent suggĂ©rer une construction plus tardive qu’on ne l’envisageait, entre la deuxiĂšme moitiĂ© du xiie siĂšcle et la premiĂšre moitiĂ© du xiiie siĂšcle. Ces dates pourraient suggĂ©rer une reconstruction partielle du donjon, sans correspondre Ă  la phase de construction originale du chĂąteau

    International audienceBackgroundGenome analysis could provide tools to assess predictive molecular biomarkers of radioresistance.MethodsHead and neck squamous cell carcinoma patients included in ProfiLER study and who underwent a curative radiotherapy were screened. Univariate and Cox multivariate analyses were performed to explore the relationships between molecular abnormalities, infield relapse and complete tumor response after radiation.ResultsOne hundred and forty-three patients were analyzed. PIK3CA mutation and genomic instability of MAP kinases pathway were found to be prognostic factors of loco-regional relapse in multivariate analysis with respectively HR 0.33, 95% CI 0.13–0.83, p = 0.005 and HR 0.61, 95% CI 0.38–0.96, p = 0.025. Instability of apoptosis pathway was found to be a prognostic factor of complete response after radiotherapy with HR 0.24, 95% CI 0.07–0.88, p = 0.04.ConclusionThis sub analysis suggests that PIK3CA mutation, variation of copy number of MAP kinases and apoptosis pathways play a significant role in the radioresistance phenomeno
