Background. The Belgian Section of Transplant Coordinators, created in 1997 under the auspices of the Belgian Transplant Society, is in charge of the collection of the national data about donor/procurement activities. Methods. Data are collected in all Belgian transplant centers. An annual report is finalized by combining these data with data from the Eurotransplant database. Results. An increase of both potential donors (n 501, 14.4%) and effective donors (n 273, 16.7%) was observed in 2006 versus 2005. Among effective donors, 28 were non–heart-beating donors (10.25%). Overall donor ratio was 26.26 donors per million inhabitants. Within potential donors, absence of organ harvesting was due to medical contraindications (28%), family refusal (13%), or legal refusal (2%). Donor mean age was 46.4 years and mean organs/donor was 3.21 1.7. An overall reduction of Belgian waiting lists was observed in 2006 as compared with 2005 ( 5.7% for kidney, 25.7% for liver, 9.4% for heart, 6.7% for lung, and 11.7% for pancreas), while waiting list mortality was 18% for liver, 11% for heart, and 7% for lung. As compared with 2005, transplant activities increased for kidney (n 485, 24.3%), heart lungs (n 73, 7.3%), and lungs (n 83, 39.4%) but decreased for liver (n 236, 2.1%). Living donation represented 8.45% for kidney ( 28.1% vs 2005) and 8% for liver transplantation ( 29.6%). Conclusion. Globally, a marked increase of procurement and transplant activities was observed in 2006, allowing to limit waiting list and waiting list mortality. Further increase of living donor activity and non–heart-beating donation remains necessary to extend the donor pool. [less ▲]

Computerized adaptive testing (CAT) is an efficient method to administer psychometric or educational tests and questionnaires. Unlike the standard fixed (“paper-and-pencil”) tests, items in a CAT are iteratively and optimally selected within a bank of available items, on the basis of previously administered items and the current ability estimate of the examinee. This general approach has several assets with respect to fixed tests: it reduces the risk of fraud, it allows for individualized questionnaires according to the examinee’s ability level, and fewer items must be administered to reach the same level of precision in the ability estimates. The purpose of this talk is threefold. First, a general overview of CAT is proposed and its main principles are quickly outlined. Second, a recently developed R package, called catR, is briefly presented and its functionalities are described. Finally, two applications are discussed. The first application is a live demonstration of catR, by using its by-default item bank about English aptitude assessment, and several CAT options. The second application focuses on the on-line testing platform Concerto, a web interface for the development and testing of CAT sessions that uses catR as underlying computational package. The R package catR was jointly developed with Gilles Raîche (Université du Québec à Montréal, Canada). The platform Concerto is under development by The Psychometrics Centre (Cambridge University, UK) under the supervision of Michal Kosinski and John Rust. [less ▲]

Historical data indicate that pituitary tumors represent 10% of intracranial tumors, while adenomas are noted in approximately 14-23% of normal subjects on autopsy or magnetic resonance imaging (MRI). About 2.5% of these tumors stain positive for GH in histopathologic studies. In contrast, the prevalence of clinically diagnosed acromegaly is lower at 36-69 per million population. Ongoing studies indicate that the actual prevalence of acromegaly in the community may be higher than previous epidemiologic data suggest. Acromegaly can occur both sporadically and in the setting of familial conditions, such as multiple endocrine neoplasia type 1 (MEN1) and Carney complex (CNC). Isolated familial somatotropinoma has been described and newer data suggest that acromegaly may also occur in non-MEN1/CNC families in combination with other pituitary tumor phenotypes. [less ▲]

The catalytic properties of three class B beta-lactamases (from Pseudomonas maltophilia, Aeromonas hydrophila and Bacillus cereus) were studied and compared with those of the Bacteroides fragilis enzyme. The A. hydrophila beta-lactamase exhibited a unique specificity profile and could be considered as a rather specific 'carbapenemase'. No relationships were found between sequence similarities and catalytic properties. The problem of the repartition of class B beta-lactamases into sub-classes is discussed. Improved purification methods were devised for the P. maltophilia and A. hydrophila beta-lactamases including, for the latter enzyme, a very efficient affinity chromatography step on a Zn(2+)-chelate column.

Posidonia oceanica is an endemic seagrass of the Mediterranean Sea. The ecosystem based on this plant is essential from an ecological and economical point of view (commercial species, touristic activities, oxygen production), though very sensitive to environmental perturbations. To detect those perturbations, scientists are trying to find more efficient ecological indicators. Most of the time, those indicators are based on the plant itself. Unfortunately, this seagrass does not react very quickly to perturbations so, when a reaction is noticed, it is often too late to prevent irremediable damages to the ecosystem. The sedimentary compartment of P. oceanica meadows has been less studied than the canopy level. However, it could be a good source of ecological indicators because it is the final container of all the pollution. In this framework, the microbenthic loop has been studied. It is a major subsystem of those meadows and encompasses organic matter, bacteria, microphytobenthos and meiofauna. As those organisms have a rapid turnover and stay almost all their life inside the sediment, they seemed good potential indicators. This presentation will show what is useful or not inside the sediment and more specifically inside the microbenthic loop. Results of a comparison between a fish farm and a reference location will be used, as well as in situ experiments (shading and sediment loading) and small spatial scale variations. At the end of this presentation, you will know what are the good, the bad and the ugly in the sedimentary compartment of a P. oceanica meadow. [less ▲]

We present a brief summary of what is currently known about white dwarf stars, with an emphasis on their evolutionary and internal properties. As is well known, white dwarfs represent the end products of stellar evolution for the vast majority of stars and, as such, bear the signatures of past events (such as mass loss, mixing phases, loss and redistribution of angular momentum, and thermonuclear burning) that are of essential importance in the evolution of stars in general. In addition, white dwarf stars represent ideal testbeds for our understanding of matter under extreme conditions, and work on their constitutive physics (neutrino production rates, conductive and radiative opacities, interior liquid/solid equations of state, partially ionized and partially degenerate envelope equations of state, diffusion coefficients, line broadening mechanisms) is still being actively pursued. Given a set of constitutive physics, cooling white dwarfs can be used advantageously as cosmochronometers. Moreover, the field has been blessed by the existence of four distinct families of pulsating white dwarfs, each mapping a different evolutionary phase, and this allows the application of the asteroseismological method to probe and test their internal structure and evolutionary state. We set the stage for the reviews that follow on cooling white dwarfs as cosmochronometers and physics laboratories, as well as on the properties of pulsating white dwarfs and the asteroseismological results that can be inferred.

Background: Clownfishes (Pomacentridae) are brightly colored coral reef fishes well known for their mutualistic symbiosis with tropical sea anemones. These fishes live in social groups in which there is a size-based dominance hierarchy. In this structure where sex is socially controlled, agonistic interactions are numerous and serve to maintain size differences between individuals adjacent in rank. Clownfishes are also prolific callers whose sounds seem to play an important role in the social hierarchy. Here, we aim to review and to synthesize the diversity of sounds produced by clownfishes in order to emphasize the importance of acoustic signals in their way of life. Methodology/Principal Findings: Recording the different acoustic behaviors indicated that sounds are divided into two main categories: aggressive sounds produced in conjunction with threat postures (charge and chase), and submissive sounds always emitted when fish exhibited head shaking movements (i.e. a submissive posture). Both types of sounds showed size-related intraspecific variation in dominant frequency and pulse duration: smaller individuals produce higher frequency and shorter duration pulses than larger ones, and inversely. Consequently, these sonic features might be useful cues for individual recognition within the group. This observation is of significant importance due to the size-based hierarchy in clownfish group. On the other hand, no acoustic signal was associated with the different reproductive activities. Conclusions/Significance: Unlike other pomacentrids, sounds are not produced for mate attraction in clownfishes but to reach and to defend the competition for breeding status, which explains why constraints are not important enough for promoting call diversification in this group.
