Hypoxia, a common feature of solid tumors, is a direct stress that triggers apoptosis in many cell types. Poor or irregular tumor vascularization also leads to a decreased drug diffusion and cancer cells distant from blood vessels (hypoxic cells) are exposed to low drug concentrations. In this report, we show that low daunomycin concentrations protect HCT116 colorectal cancer cells from hypoxia-induced apoptosis. While hypoxia induced p53 accumulation without expression of its responsive genes (bax and p21), daunomycin treatment restored p53 transactivation activity and cell cycle progression. We also demonstrated a role for Akt activation in daunomycin-induced protection through phosphorylation and inactivation of the Bcl-2 family proapoptotic factor Bad. Our data therefore suggest that chemotherapy could possibly, because of low concentrations in poorly vascularized tumors, protect cancer cells from hypoxia-induced cytotoxicity. [less ▲]

The [SUP]12[/SUP]C[SUP]14[/SUP]N/[SUP]12[/SUP]C[SUP]15[/SUP]N and [SUP]12[/SUP]C[SUP]14[/SUP]N/[SUP]13[/SUP]C[SUP]14[/SUP]N isotopic ratios have been determined in comets C/1995 O1 (Hale-Bopp), C/2001 Q4 (NEAT) and C/2003 K4 (LINEAR) at heliocentric distances of, respectively, 2.7, 3.7 and 2.6 AU. These ratios have also been measured at rË 1 AU. No significant differences were found between all determinations, nor with the value obtained for other comets. If confirmed, the discrepancy between the nitrogen isotopic ratios from optical and millimeter measurements on CN and HCN would rule out HCN as a major parent of the cometary CN radicals. Based on observations collected at the European Southern Observatory, Paranal, Chile (ESO Programmes 270.C-5043, 073.C-0525 and 274.C-5015). [less ▲]

We present the results of the mode identification for a sample of 7 bright southern slowly pulsating B stars showing one pulsation frequency in the lambdalambda 413 nm Si II profiles. We combined the results from (1) the method of photometric amplitudes; (2) the moment method; and (3) the amplitude and phase variation across the profile to search for the l and m values of the modes best fitting the data. It is the first time that the applicability of these techniques is tested to a sample of main-sequence g-mode pulsators. Combining the moment method with the amplitude and phase variations across the observed line profile gives an improvement in spectroscopic identification of low degree l g-mode pulsations. Using the variations of the higher order even moments < v[SUP]4[/SUP]> and < v[SUP]6[/SUP]> of the moment method solutions can also help. For HD 181558, HD 24587, HD 140873 and HD 177863, the photometric and spectroscopic results are compatible and point towards (l,m) = (1, +1) sectoral modes. For HD 215573, HD 53921 and HD 92287, the results are inconclusive. Our proposed methodology for mode identification is also applicable to gamma Doradus stars. Based on observations collected with the CAT Telescope of the European Southern Observatory and with the Swiss Photometric Telescope of the Geneva Observatory, both situated at La Silla in Chile.

Are the universalisation and the globalisation of trade exchanges synonymous with a standardization in which agro-food products uprooted of their soil will no longer be differentiated from manufacturers or supermarket brands? Original food products belong to the inheritance of the territories and the consumers are attracted more and more by their authenticity. The GeoTraceAgri project resolutely supports agriculture and the sustainable promotion of the territory as opposed to universalisation which standardizes and moves away those who produce for consumers. Geotraceability aims at associating information of geographical nature with the traditional data of traceability. Farming origin and operations have become factual and verifi able data is available everywhere in the world, thus making it possible to bring additional guarantees to the signs of quality. The GeoTraceAgri (GTA) project largely contributed to the realisation of geotraceability. With the implementation from January 1,2005 of the new Common Agricultural Policy and its regulation imposing on the Member States a single system of declaration, all the agricultural parcels now form part of a European database of geographical references. This new regulation reinforces the basis of the concept of geotraceability, whereas throughout the project it was necessary to defi ne geo-indicators for integrated or crop production with very few geographical data on the farming precedents. The development of the GTA prototype rests on a decentralized architecture and Web services. It was indeed necessary to conceive a system which is readily accessible on Internet for farmers, co-operatives and collectors, and potentially with the administrations which have control responsibilities. In term of acceptability, the potential users realise the potential economic benefi ts of the concept and of the indicators of geotraceability in their plan of exploitation, on the other hand sociological acceptability is less evident which induces the need for communication to make for its adoption. This fi nal report fi nal illustrates the fi rst stage : the GeoTraceAgri partners are continuing their research on the defi nition of an integrated system of geotraceability for the Common agricultural policy and the plan of analysis of the results of GeoTraceAgri should lead to the marketing within two years of an application making it possible to integrate the geo-indicators into management software for the actors of the agro food chain.

We report the case of an ascending aortic aneurysm involving the aortic root, with a functionally competent bicuspid aortic valve, treated by the David's operation. This operation allows to fix the aortic root pathology, whilst preserving the native aortic valve. The technical aspects, surgical indications, and potential benefits of this operation are reviewed.

A karyotype of 2n = 52 chromosomes was found in two Eliomys quercinus (Linnaeus, 1766) specimens from two different localities of Tirol (Austria). The karyotype is similar to the one described in the Italian Alps, suggesting that these mountains were not a barrier to the northern expansion of this chromosomal race. [less ▲]
