The mechanisms of seasonal acclimatization in eurythermal fish such as common carp are not fully understood. Here, we concentrate on the regulation of pituitary factors, as this organ was shown to be highly affected by seasonal changes. We cloned and sequenced two different cDNAs for each of the transcription factors Pitx2 and Rpx, known to play a role in pituitary development. We show that these genes are conserved throughout evolution, to different degrees depending on the specific domain considered. Finally, we show that the cDNAs for both factors are clearly up-regulated during the winter season, in sharp contrast to other regulators such as Pit1 or pituitary hormone genes such as prolactin (prl) and growth hormone (gh). Our results suggest that increased expression of Pitx2 and Rpx contributes to seasonal adaptation of common carp to winter conditions. [less ▲]

Thesauri are used for document referencing. They define hierarchies of domains. We show how document and domain contents can be used to validate and update a classification based on a thesaurus. We use document indexing and classification techniques to automate these operations. We also draft a methodology to systematically address those issues. Our techniques are applied to Urbamet, a thesaurus in the field of town planning. [less ▲]

This paper introduces a new optimization heuristic for the robustification of critical inputs under consideration in many problems. It is shown that it allows to improve significantly the quality and the stability of the results for two classical financial problems, i.e. the Markowitz' portfolio selection problem and the computation of the financial beta. Focus here is on the robust Minimum Covariance Determinant (MCD) estimator which can easily be substituted to the classical estimators of location and scatter. By definition, the computation of this estimator gives rise to a combinatorial optimization problem. We present a new heuristic, called 'RelaxMCD', which is based on a relaxation of the problem to the continuous space. The utility of this approach and the performance of our heuristic, with respect to other competitors, are illustrated through extensive simulations. [less ▲]

The oncogenic protein BCL-3 activates or represses gene transcription through binding with the NF-kappaB proteins p50 and p52 and is degraded through a phospho- and GSK3-dependent pathway. However, the mechanisms underlying its degradation remain poorly understood. Yeast-two-hybrid analysis led to the identification of the proteasome subunit PSMB1 as a BCL-3-associated protein. The binding of BCL-3 to PSMB1 is required for its degradation through the proteasome. Indeed, PSMB1-depleted cells are defective in degrading polyubiquitinated BCL-3. The N-terminal part of BCL-3 includes lysines 13 and 26 required for the K48-linked polyubiquitination of BCL-3. Moreover, the E3 ligase FBW7 known to polyubiquitinate a variety of substrates phosphorylated by GSK3 is dispensable for BCL-3 degradation. Thus, our data defined an unique motif of BCL-3 that is needed for its recruitment to the proteasome and identified PSMB1 as a key protein required for the proteasome-mediated degradation of a nuclear and oncogenic IkappaB protein.

Environment plays a major role for determining the kind of courtship behaviours or alternative mating tactics employed, but the effect of physical variables on fitness has received little attention. The Alpine newt courts during both day and night times and exhibits a complex suite of behaviours involving olfactory, visual and tactile cues. Displaying in both dark and light conditions may increase the number of mating opportunities and alleviate predation risk, but the frequency and efficacy of the various tactics deployed may vary across light conditions, leading males to vary their use of these tactics across different light regimes. To test this hypothesis, we video-recorded sexual encounters at two light intensities in a controlled experimental design. When courting in the dark, males used comparatively more olfactory rather than visual displays. They also relied more on positive feedback from the female before releasing a spermatophore for her to pick up. The particular mix of tactics used under each light condition is likely to be adaptive because in the dark (1) visual communication is hampered, making olfactory displays possibly more effective and (2) males depositing spermatophores are more likely to lose fertilizations to competitors. Mating in light and dark conditions has similar reproductive payoffs, which shows that displaying in the dark is not detrimental and may even be advantageous if predation risk is reduced at night. These results confirm the importance of taking into account physical variables to understand the evolution of sexual communication in animals. [less ▲]

A pruritic vesicular, pustular or squamous eruption confined to the lateral aspect of fingers or toes corresponds to the overall pattern of dysidrosis. Such a clinical pattern is defined by its peculiar topography. It is encountered in diseases resulting from various etiologies. Thus, conceptually, dysidrosis is a common clinical aspect shared by diverse disorders related to different etiologies and pathomechanisms. The dermatopathological assessment and the patch test procedure shed some light on this nosological diversity. Allergic contact dermatitis, irritation dermatitis, mycids, alterations of acrosyringia, and drug or food reactions are eventually involved in this process. However, most cases of dysidrotic dermatoses do not disclose their origins and they remain idiopathic. [less ▲]

After briefly introducing the sedimentology of two Eifelian-Frasnian carbonate sections in Belgium and Moravia, this paper focuses on the comparison of the magnetic susceptibility (MS) curves. The Ardennes section shows highly variable facies, with an alternation of ramp, platform and mound environments. Detrital inputs are locally very important. Time-equivalent facies in the area of the Moravian Karst correspond to rather pure carbonate platform facies, mostly composed of Amphipora beds. This first analyse of long-term trends in Devonian MS in Belgium and Moravia shows a remarkable similarity, despite a very different background of palaeogeographical setting, facies, sedimentary rate and retrogradation-progradation history. However, a relative independence of the MS and the distal-proximal curves, deduced either from the microfacies record (Ardennes) or from shoreline shifts (Moravia) is observed. This questions the nature of the forcing mechanisms that must at least be active at the inter-regional scale. Moravia and the Ardennes are located along the same palaeolatitude, perhaps suggesting some climatically driven mechanisms, responsible for the input of the detrital fraction responsible for the MS in these sediments. Trade winds are potentially responsible for transportation of dust and its widespread distribution in intertropical areas. [less ▲]
