Un nouvel atelier de potiers de la fin de lâĂąge du Fer dĂ©couvert Ă Simorre (Gers)
Le site de la rue de CassaĂ«t Ă Simorre (Gers) a Ă©tĂ© dĂ©couvert de maniĂšre fortuite, en 2001, par Robert Abila (inrap), chez un particulier, Ă lâoccasion du creusement dâune tranchĂ©e dans laquelle a Ă©tĂ© mise au jour une fosse dĂ©potoir de la TĂšne finale. En mars 2002, une opĂ©ration archĂ©ologique de sauvetage a permis dâassurer le dĂ©capage et le relevĂ© des structures protohistoriques encore prĂ©servĂ©es sur la bande de terrain assiette des travaux dâextension de la cantine scolaire. Une sĂ©rie de fours a pu ĂȘtre Ă©tudiĂ©e ainsi quâune succession dâamĂ©nagements connexes liĂ©s Ă lâactivitĂ© quotidienne de lâatelierâ: fosse dâextraction dâargile, fosse dĂ©potoir, foyer sur pierres chauffĂ©es. Des structures en creux ont Ă©galement Ă©tĂ© fouillĂ©esâ: elles tĂ©moignent de lâamĂ©nagement de lâespace artisanal et permettent de confirmer la prĂ©sence dâune installation pĂ©renne de lâartisanat de la poterie sur le site de Simorre au dĂ©but du Ierâs. av. J.-C.The rue de CassaĂ«t site at Simorre (Gers), was fortuitously discovered in 2001 by Robert Abila (INRAP), on private land. During the excavation of a trench, a La TĂšne deposit was brought to light. In March 2002, a rescue archaeological operation allowed the exposure and survey of this protohistoric site. The structures were still well preserved on the surface of an area where an extension of a school canteen was constructed. This work allowed us to study a series of ovens, as well as a sequence of features related to the daily activity of a workshop: a clay extraction pit, a dump, and a hearth on heated stones. Negative features were also excavated: they confirmed the installation of artisan spaces and allow us to confirm the presence of permanent potters' installations on the Simorre site of at the beginning of the first century BC

In Vitro Reconstitution of SARS-Coronavirus mRNA Cap Methylation
SARS-coronavirus (SARS-CoV) genome expression depends on the synthesis of a set of mRNAs, which presumably are capped at their 5âČ end and direct the synthesis of all viral proteins in the infected cell. Sixteen viral non-structural proteins (nsp1 to nsp16) constitute an unusually large replicase complex, which includes two methyltransferases putatively involved in viral mRNA cap formation. The S-adenosyl-L-methionine (AdoMet)-dependent (guanine-N7)-methyltransferase (N7-MTase) activity was recently attributed to nsp14, whereas nsp16 has been predicted to be the AdoMet-dependent (nucleoside-2âČO)-methyltransferase. Here, we have reconstituted complete SARS-CoV mRNA cap methylation in vitro. We show that mRNA cap methylation requires a third viral protein, nsp10, which acts as an essential trigger to complete RNA cap-1 formation. The obligate sequence of methylation events is initiated by nsp14, which first methylates capped RNA transcripts to generate cap-0 7MeGpppA-RNAs. The latter are then selectively 2âČO-methylated by the 2âČO-MTase nsp16 in complex with its activator nsp10 to give rise to cap-1 7MeGpppA2âČOMe-RNAs. Furthermore, sensitive in vitro inhibition assays of both activities show that aurintricarboxylic acid, active in SARS-CoV infected cells, targets both MTases with IC50 values in the micromolar range, providing a validated basis for anti-coronavirus drug design
Représentations graphiques et indicateurs des mobilités et des dynamiques de peuplement : contribution bibliographique
La Base Endnote sera adressée à toute personne en faisant la demande auprÚs de Françoise Dureau : [email protected] main goal of the MOBIDYC research project (Mobilities and population movement: graphics and indicators) was to contribute to the definition of processing sequences that integrate both temporal and spatial dimensions of information related to spatial mobility (be it migration, residential mobility or daily mobility). Workshops were held on a quarterly basis to bring team members together. Between meetings, members worked separately on their own datasets. A first workshop was dedicated to the sharing of experience from previous work by members of the team. Then we focused on inventorying other experiences through bibliographic research. The aim of this article is to make the results of this research available to the scientific community. After stating the whys and hows of the collection of this bibliographic corpus, we present the material in the appendix: an Endnote set of references, along with a descriptive table synthesizing the content of these references. Finally, we present the main lessons we have learned through the analysis of this bibliographic corpus and from tests we carried out based on the methods described in the literature.L'objectif général du projet MOBIDYC (Mobilités et dynamiques de peuplement : représentations graphiques et production d'indicateurs) était d'avancer dans la définition de chaßnes de traitement de l'information sur les mobilités spatiales (biographies migratoires et résidentielles, trajectoires de mobilité quotidienne) intégrant les deux dimensions, temporelles et spatiales, de l'information. La méthode de travail a consisté en un atelier réunissant les membres de l'équipe à un rythme trimestriel ; entre les séances de l'atelier, les chercheurs impliqués dans le projet ont travaillé en parallÚle sur leurs corpus de données respectifs. AprÚs une premiÚre étape consacrée à la mutualisation de nos expériences respectives, l'accent a été mis sur la recherche bibliographique et la recension des expériences dans le champ du projet. L'objectif de cet article est de mettre à disposition de la communauté scientifique le résultat de ce travail bibliographique. AprÚs avoir rappelé les objectifs et conditions de réalisation de la base de données bibliographiques, nous présentons les informations mises à disposition en annexes de cet article : tableau de description synthétique des références bibliographiques, et la base Endnote des références . Enfin, nous livrons les principaux enseignements que nous avons tirés de l'analyse de ce corpus bibliographique, et des tests effectués à partir des méthodes identifiées dans la littérature
Aspergillus PCR in Bronchoalveolar Lavage Fluid for the Diagnosis and Prognosis of Aspergillosis in Patients With Hematological and Non-hematological Conditions
Objectives: We evaluated the usefulness of an Aspergillus fumigatus quantitative PCR assay performed in bronchoalveolar lavage fluid (BAL) for the diagnosis and prognosis of both invasive and non-invasive aspergillosis.Methods: This 4-year retrospective study involved 613 at-risk patients who had either hematological disorders or other immunosuppressive conditions, notably solid organ transplants. Thirty-five patients had proven/probable aspergillosis and thirteen had chronic non-invasive aspergillosis. We compared PCR, galactomannan index and mycological analysis of BAL.Results: For invasive aspergillosis (IA), PCR performed in BAL yielded 88.6% sensitivity and 95.5% specificity. Comparatively, galactomannan index and mycological examination yielded only 56.3 and 63.6% sensitivity and 97.6 and 94.5% specificity, respectively. Considering the 13 chronic aspergillosis cases, PCR, galactomannan index and mycological examination yielded 76.9, 15.4, and 84.6% sensitivity and 92.2, 94.9, and 93% specificity, respectively. Fungal load in BAL evaluated by PCR was able to discriminate between aspergillosis and contamination, but not between invasive and non-invasive forms. Finally, fungal load was predictive of 90-day mortality, with 23.1% mortality for patients with less than 500 copies/mL versus 68.4% for patients above that cut-off (p < 0.05).Conclusion: Our results indicate that Aspergillus PCR in BAL is of particular interest for both the diagnosis and the prognosis of IA. It is likewise an interesting tool for the diagnosis of non-invasive forms
Darwinâs wind hypothesis: does it work for plant dispersal in fragmented habitats?
Using the wind-dispersed plant Mycelis muralis, we examined how landscape fragmentation affects variation in seed traits contributing to dispersal.
Inverse terminal velocity (Vtâ1) of field-collected achenes was used as a proxy for individual seed dispersal ability. We related this measure to different metrics of landscape connectivity, at two spatial scales: in a detailed analysis of eight landscapes in Spain and along a latitudinal gradient using 29 landscapes across three European regions.
In the highly patchy Spanish landscapes, seed Vtâ1 increased significantly with increasing connectivity. A common garden experiment suggested that differences in Vtâ1 may be in part genetically based. The Vtâ1 was also found to increase with landscape occupancy, a coarser measure of connectivity, on a much broader (European) scale. Finally, Vtâ1 was found to increase along a southânorth latitudinal gradient.
Our results for M. muralis are consistent with âDarwinâs wind dispersal hypothesisâ that high cost of dispersal may select for lower dispersal ability in fragmented landscapes, as well as with the âleading edge hypothesisâ that most recently colonized populations harbour more dispersive phenotypes.
