Les ouvrages de pierres dressées sont une composante essentielle de l’étude générale des mégalithes de la Préhistoire récente. Mais la perduration du phénomène ouest-européen, sur près de trois millénaires, laisse supposer des nuances qui à l’heure actuelle sont peu perceptibles, faute d’observations suffisantes sur un objet architectural au surplus difficile à définir. Dans l’ouest de la France, les « alignements de menhirs » en roche quartzitique forment un sous-ensemble original mal connu. Leur encadrement chronologique apparaît comme une priorité. L’exercice a été entamé sur un site inédit en forêt du Gâvre (nord de Nantes) à l’aide de trois sondages restreints permettant d’accéder aux couches archéologiques au contact de trois monolithes. A titre expérimental, une datation OSL directe a été envisagée, mais les grains de quartz provenant des trois blocs et d’une pierre de calage également en quartz n’ont pas émis de signal de luminescence suffisant pour être traité. Une alternative a néanmoins été proposée en datant le dépôt des sédiments du comblement de la fosse du monolithe N15. L’intervalle de dates [2040-1680] av. J.-C. situe le creusement de la fosse et donc l’érection de la stèle dans le Bronze ancien. Cette datation est en accord avec celle obtenue pour le second sondage N6 A [1752-1628] grâce à l’analyse C14 d’un charbon de bois de la fosse d’implantation. [less ▲]

When Pieter Bruegel the Elder died in 1569, his elder son and principal continuator, Pieter Brueghel the Younger, was only four or five years old. The amazingly faithful replicas by the latter were therefore made decades later, after models that were not always the original versions, disseminated at that time; they also relied on a treasure trove of working drawings inherited from Bruegel the Elder. Reconstructing this lost preparatory material through the evidence uncovered during technical examination of the copies of his sons (especially Pieter’s but also Jan’s) is one aspect that will be illustrated in this paper through a few key case studies such as the Battle between Carnival and Lent, the Sermon of St John the Baptist and the Wedding Dance in the Open Air. The presentation will thus describe the actual methods of both the creator and his foremost copyist, based on combined results of infrared reflectography, practical reconstructions and comparisons of tracings of their respective paintings. Brueghel the Younger’s vast and successful copying enterprise required a streamlined production process, and this gradually came to light over the technical research into 60+ paintings by the artist and his workshop. The most interesting discoveries on his techniques and materials – supports, preparatory layers, underdrawings, and pigments – will be illustrated through different examples of his work. This evidence, seen in conjunction with the evidence of the transfer technique, allows us to distinguish his production from that of rival copyists. The realisation that Brueghel the Younger’s copies of the same composition are not all alike and that there are often several variants of them will be considered in relation to the organization of work within – and possibly outside – his workshop. This issue, examined alongside that of the attribution of the copies within series, gives us a more nuanced view of Brueghel the Younger’s output and working practice. [less ▲]

The duration of orthodontic treatments in adult patient remains a barrier for some patients. The recent scientific reports describing piezocision technique involving minimally invasive corticotomies, seem to be of interest for these particular cases. The present communication describes the clinical case of a 20-year-old patient presenting a class I bilateral, an overcrowding of front areas with the superior canine in mesio-infraclusion and a deviated lower median line. An excellent multidisciplinary approach is mandatory for the planification of such cases. Under local anesthesia, the surgical technique involves vertical minimal incision around the teeth that need to be moved. Trough the minimal incisions, 5mm vertical alveolar osteotomies are performed using ultrasonic surgical device. No suture is necessary. The orthodontic activation is applied 1 week before the surgical procedure and the patient is recalled every 15 days to activate the orthodontic appliance. In this case self-ligating brackets were used to reduce the friction. Post-operative outcomes were painless for the patient and the complete orthodontic procedure took 7 months. The overall treatment appeared to be faster than a conventional orthodontic treatment. However, even if animal studies seem to confirm the clinical feeling described in this case report, further clinical studies including randomized controlled trials are needed to validate this treatment approach.

Thiamine triphosphate (ThTP) is found in most organisms and may be an intracellular signal molecule produced in response to stress. We have recently cloned the cDNA coding for a highly specific mammalian 25-kDa thiamine triphosphatase. The enzyme was active in all mammalian species studied except pig, although the corresponding mRNA was present. In order to determine whether the very low ThTPase activity in pig tissues is due to the absence of the protein or to a lack of catalytic efficiency, we expressed human and pig ThTPase in E. coli as GST fusion proteins. The purified recombinant pig GST-ThTPase was found to be 2-3 orders of magnitude less active than human GST-ThTPase. Using site-directed mutagenesis, we show that, in particular, the change of Glu85 to lysine is responsible for decreased solubility and catalytic activity of the pig enzyme. Immunohistochemical studies revealed a distribution of the protein in pig brain very similar to the one reported in rodent brain. Thus, our results suggest that a 25-kDa protein homologous to hThTPase but practically devoid of enzyme activity is expressed in pig tissues. This raises the possibility that this protein may play a physiological role other than ThTP hydrolysis. [less ▲]
