The BCG vaccine has demonstrated its efficacy to protect young children from severe extrapulmonary forms of tuberculosis. Nevertheless, the immunity induced by the vaccine disappears in adults and cannot be boosted by readministration of BCG. Adverse effects of BCG are rare, but potentially dangerous (i.e. disseminated vaccinal infections) and they justify the fact that BCG should not be administered anymore in Western European countries where the incidence of pediatric tuberculous meningitis is very low. The vaccine is still recommanded for children living in countries with high tuberculosis prevalence and for resident children leaving Belgium for these countries. [less ▲]

The study of biogeochemical processes in soil has long been restricted by the techniques available for investigating the micro-organisms concerned. In particular, isolated nitrifying bacteria are not active in culture media below pH 5.5-6.0, and it is not clear to what extent these strains, if at all, are active in the acid soils of temperate forests. Since DNA/RNA based microbiological techniques do not require isolation of bacterial strains, they provide a new, powerful approach to gain insight into the nitrification process. We therefore combined the use of a large scale field experiment and laboratory soil incubations with molecular analysis of the nitrifying bacterial community to investigate the effect of dolomite lime on the nitrification process in the soil of the Belgian Ardenne. In this area, soils are naturally poor in magnesium and liming at moderate doses has been suggested to alleviate soil acidification and nutritional deficiencies. However, possible side effects needed to be evaluated, in particular on the nitrification process. As nitrification may be linked to soil acidification, cation leaching, aluminium mobilisation and N2O emission, increased knowledge is essential when evaluating effects of global environmental change and management strategies on forest ecosystems. The effects of dolomite lime (3-5 T/ha) were investigated at the watershed (80 ha, mainly Picea abies), plot (Quercus petraea and Picea abies stands) and laboratory level. Runoff chemistry, soil solution, net nitrate production in the laboratory and the community structure of ammonium oxidising bacteria (by PCR amplification of 16S-RNA genes, Denaturing Gradient Gel Electrophoresis - DGGE, sequence analysis and hybridisation) were analysed. In the watersheds, consequences on runoff water chemistry were minor. However, in the plot study, soil solution nitrate concentrations were significantly increased through liming in the Quercus plots. Increased net nitrification in the Quercus stand was confirmed by potential net nitrification measurements in the laboratory, whereas soil pH rose in both stands. The impact of liming on potential net nitrification was not related to a shift in the 16S rDNA DGGE community profile of ammonia-oxidising bacteria. The DDGE profile, combined with hybridisation and sequencing of cut out bands revealed a dominance of Nitrosomonas europea-like sequences and a minor presence of Nitrosospira cluster 2-like sequences. These results contrast with several reports suggesting a dominance of Nitrosospira-like organisms among ammonia oxidiser communities in acid soils. Our study reflects the great potential of combining new molecular techniques with conventional methods for improving our knowledge on the ecology of biogeochemical processes. [less ▲]

Recent models of verbal short-term memory (STM) propose a distinction between item storage processes, which are viewed as domain-specific, and order storage processes, which are considered by some authors to be domain-general, at least as regards verbal and visual STM domains. Here we provide further evidence for domain-specific item STM processes and domain-general order STM processes by comparing item and order processing in verbal and musical STM domains. The musical domain is particularly relevant here given its reliance on different kinds of sequential processes (e.g., tones successions, rhythm). Using an interindividual differences approach, we administered to a group of young healthy adults different tasks requiring retention of item identity for words or tones, and tasks requiring retention of serial order information for word sequences or note sequences, as well as a task measuring retention abilities for rhythmic information. For the item STM tasks, we observed strong intercorrelations for within-domain WM measures, but not between-domain WM measures, after controlling for general WM abilities. For the serial order STM tasks, we observed a specific association with the rhythm STM task. These results highlight the importance of temporal sequential processes, as measured by the rhythm STM task, as a driving factor of domain-general STM processes in verbal and musical domains. They furthermore confirm the domain-specificity of item STM processes. [less ▲]

TEL is a novel member of the ETS family of transcriptional regulators which is frequently involved in human leukemias as the result of specific chromosomal translocations. This study shows that the amino-terminal domain conserved in a subset of the ETS proteins has evolved to generate a specialized protein-protein interaction interface which is likely to be an important determinant of their specificity as transcriptional regulators.

At rotational velocities such as that of upper Main Sequence stars - between 50 to 200 km/s - the effects of rotation on oscillation frequencies must be included. Considering the accuracy reached by available ground-based and space observations, the aim of this study is to determine the limits - in terms of rotational velocity - of a perturbative approach to model the effects of rotation on oscillation frequencies. We thus compare the oscillation frequencies computed by 1D second order perturbative methods to the ones obtained in Reese et al. (2006) - direct integration of a 2D eigenvalue system. To do so, we use polytropic models (N=3) in uniform rotation, and we discuss the results for a beta Cephei star (8.2 M_{o}, 5.04 R_{o}). [less ▲]

The regular model-checking approach is a set of techniques aimed at exploring symbolically infinite state spaces. These techniques proceed by representing sets of configurations of the system under analysis by regular languages, and the transition relation between these configurations by a transformation over such languages. The set of reachable configurations can then be computed by repeatedly applying the transition relation, starting from a representation of the initial set of configurations, until a fixed point is reached. In order for this computation to terminate, it is generally needed to introduce so-called acceleration operators, the purpose of which is to explore in one computation step infinitely many paths in the transition graph of the system. A simple form of acceleration operator is one that is associated to a cycle in the transition graph, computing the set of states that can be obtained by following this cycle arbitrarily many times. The computation of acceleration operators is strongly dependent on the type of the data values that are manipulated by the system, and on the symbolic representation chosen for handling sets of such values. In this survey, we describe acceleration operators suited for the regular state-space exploration of systems relying on FIFO communication channels, as well as those based on integer and real variables.
