Background: Mutations in the Aryl hydrocarbon receptor Interacting Protein (AIP) gene have been described in about 15% of kindreds with Familial Isolated Pituitary Adenomas (FIPA) and in a minority of early onset sporadic pituitary adenomas (PA). Among the AIP mutations reported so far, the R304X (AIPR304X) represents, together with the "Finnish mutation" Q14X, the most common one. Methods: Three AIPR304X Italian families, including a newly reported kindred, have been genotyped for 12 genetic markers surrounding the AIP gene in order to look for a potential founder effect in Italy. Disease penetrance and genotype-phenotype correlations were also addressed. Results: Analysis of chromosome 11' genetic markers revealed a common haplotype in two AIPR304X kindreds originating from central Italy. Overall, seventeen mutations carriers were identified, including 7 patients and 10 unaffected subjects, respectively, arguing in this case for a disease penetrance of 41%. Mean age at diagnosis was 19.1+/-6.7 years-old, with females tending to be older than males. Though most PA were somatotropinomas (6/7), a great variability in disease severity was observed, even between subjects sharing the same at-risk haplotype. Conclusion: These data provide strong evidence for a new founder effect of the AIPR304X mutation in central Italy and the observed variations in disease severity point out the role of additional genetic or environmental factors in such kindreds.

La possession d’armements nucléaires n’est pas un phénomène irréversible. Partant de cette idée, nous nous sommes interrogés non pas sur ce qui fait que la France a acquis des armements nucléaires mais sur la raison pour laquelle elle les conserve. En l’occurrence, notre attention s’est portée sur la période qui s’étend de 1990 à 2000 pendant laquelle un débat stratégique nucléaire relativement important se développe. Il est l’occasion pour les stratégistes de réaffirmer l’utilité de l’arme. A travers ce débat, les stratégistes décrivent un contexte international incertain et qu'ils ne considèrent pas comme mûr pour remettre en question la pertinence de l'armement nucléaire. [less ▲]

We present a cooperative framework for content-based image retrieval for the realistic setting where images are distributed across multiple cooperating servers. The proposed method is in line with bag-of-features approaches but uses fully data-independent, randomized structures, shared by the cooperating servers, to map image features to common visual words. A coherent, global image similarity measure (which is a kernel) is computed in a distributed fashion over visual words, by only requiring a small amount of data transfers between nodes. Our experiments on various image types show that this framework is a very promising step towards large-scale, distributed content-based image retrieval. [less ▲]

The Canary Island region is rich in mesoscale phenomena that affect cycles of physical and biological processes. A 1D version of the Regional Oceanic Modeling System (ROMS) is used south of the Gran Canaria Island to simulate seasonal climatologies of these cycles. The model is forced with monthly air–sea fluxes averaged from 1993 to 2002 and initialized with mean in situ profiles of temperature, salinity, oxygen and nitrate concentrations. The K-Profile Parameterization (KPP) mixed layer submodel is compared with other submodels using idealized numerical experiments. When forced with realistic air–sea fluxes, the model correctly reproduces the annual cycle of temperature (mixed layer depth), with minimum surface values of 18 °C (maximal depth > 105 m) in February during convective mixing resulting from a negative heat flux. Maximum temperatures above 23 °C (minimal depth < 20 m) are simulated from September to October after strong summer heating and a decrease in Trade Winds intensity. A simple ecosystem model is coupled to the physical model, which provides simulated biological cycles that are in agreement with regional observations. A phytoplankton bloom develops in late winter, driven by the injection of new nutrients into the euphotic layer. Simulated chlorophyll shows a deep maximum fluctuating around 100 m with concentrations around 1 mg Chla /m³, while surface values are low (around 0.1 mg Chla /m³) during most of the year. The physical and biological model results are validated by comparisons with data from regional studies, climatological fields and time-series from the ESTOC station. [less ▲]

Although water rockets are widely used to illustrate first year physics principles, accurate measurements show that they outperform the usual textbook analysis at the beginning of the thrust phase. This paper gives a more thorough analysis of this problem. It is shown that the air expansion in the rocket is accompanied by water vapor condensation, which provides an extra thrust; the downward acceleration of water within the rocket also contributes to the thrust, an effect that is negligible in other types of rockets; the apparent gravity resulting from the acceleration of the rocket contributes as much to water ejection as does the pressure difference between the inside and outside of the rocket; and the water flow is transient, which precludes the use of Bernoulli’s equation. Although none of these effects is negligible, they mostly cancel each other, and the overall accuracy of the analysis is only marginally improved. There remains a difference between theory and experiment with water rockets. [less ▲]

In models with flavour symmetries added to the gauge group of the Standard Model the CP-violating asymmetry necessary for leptogenesis may be related with low-energy parameters. A particular case of interest is when the flavour symmetry produces exact Tri/Bi-maximal lepton mixing leading to a vanishing CP-violating asymmetry. In this paper we present a model-independent discussion that confirms this always occurs for unflavoured leptogenesis in type I see-saw scenarios, noting however that Tri/Bi-maximal mixing does not imply a vanishing asymmetry in general scenarios where there is interplay between type I and other see-saws. We also consider a specific model where the exact Tri/Bi-maximal mixing is lifted by corrections that can be parametrised by a small number of degrees of freedom and analyse in detail the existing link between low and high-energy parameters—focusing on how the deviations from Tri/Bi-maximal are connected to the parameters governing leptogenesis.

Le cancer du sein touche une femme sur huit dans les pays occidentaux. Son incidence a considérablement augmenté au cours de ces deux dernières décennies mais, en même temps, le niveau de mortalité spécifique est resté stable et a même diminué en Europe et aux Etats-Unis, notamment, grâce à l’apport de nouvelles armes thérapeutiques, aux changements dans l’utilisation du traitement hormonal substitutif à la ménopause et à un diagnostic plus précoce. Malgré cela, le cancer du sein reste la première cause de décès par cancer chez la femme de moins de 65 ans. Le cancer du sein «triple négatif», un sous-type représentant environ 10 % des cancers du sein, est caractérisé par l’absence de récepteurs hormonaux aux oestrogènes et à la progestérone et l’absence d’expression du facteur de croissance HER-2 en étude d’immunohistochimie. Ce type de cancer du sein est associé à un profil clinique défavorable avec un haut risque de rechute métastatique précoce. De plus, le cancer du sein «triple négatif» ne présente aucune cible thérapeutique propre et son pronostic est donc particulièrement mauvais. La définition de facteurs prédictifs de la réponse tumorale aux différents traitements et l’apport des thérapies ciblées sont deux pistes susceptibles d’améliorer la prise en charge et la survie des patients atteints par ce type de cancer extrêmement agressif.
