On 4th December 2008, 234 students in political and social sciences of the Université de Liège, Belgium, were invited to “Draw Belgium” on a blank sheet of paper. No other guidelines were given, so total freedom was left to the students. In addition to this request, the young citizens were asked to fill in a 19-question questionnaire about their federal perceptions and preferences as well as some political and socio-demographic indicators. The analysis of the results does contain interesting material for discussion about memory process and about attitudes towards European integration [less ▲]

In order to promote IPM programmes in potato, the toxicity of 19 fungicides, 4 herbicides and 11 insecticides commonly used in this crop in Belgium was assessed on three beneficial arthropods. These species were representative of the most important aphid specific natural enemies encountered in potatoes: a parasitic wasp--Aphidius rhopalosiphi (De Stefani-Perez) (Hym., Aphidiidae), a ladybird--Adalia bipunctata (L.) (Col., Coccinellidae) and a hoverfly--Episyrphus balteatus (Dipt., Syrphidae). In a first time, pesticides were tested on glass plates on A. rhopalosiphi adults and A. bipunctata and E. balteatus larvae. For each insect, products inducing corrected mortality (Mc) lower than 30% were directly classified in a positive list for harmless products (green list). The other compounds were further tested on plants and listed in toxicity classes according to mortalities induced during this extended laboratory test: harmless (Mc < 30%), slightly harmful (30% < Mc < 60%), moderately harmful (60% < Mc < 80%) and harmful (Mc > 80). A chemical determination of pesticides residues was also performed for each experiment in order to determine the exposure of beneficial arthropods to pesticide residues and to validate the application of chemicals on tested substrates. On the basis of the results of acute toxicity tests, the period of each pesticide use according to normal agricultural practices and the abundance and importance of the three different groups of aphid natural enemies at different periods of the year, four pesticides lists were built up. Each list corresponded to a different period of pesticides application: Period I--from seedling to beginning of June (based on A. rhopalosiphi tests), Period II--beginning to end of June (based on A. rhopalosiphi tests), Period III beginning to end of July (based on E. balteatus and A. bipunctata tests) and Period IV--August to harvest (no exposure of beneficials). Results showed that herbicides were not toxic to the three species and can be used according to normal agricultural practices without restrictions. All fungicides can also be used without restrictions at recommended rates. Only the mixture Metalaxyl-M + Fluazinam was slightly harmful to A. bipunctata but had no effects on A. rhopalosiphi and E. balteatus. Results were more contrasted for insecticides and none of them was totally selective for all the 3 beneficial arthropods. Therefore, they can only be used with restrictions at periods II and III, according to the beneficial species that need to be protected. [less ▲]

The motivational value assigned to cues (CSs) associated with reward (UCS) is known as incentive salience, and is determined through the synergy of previous learning of the CS-UCS association (the sum of experiences an individual has with that cue-reward combination) and the mesolimbic state of the individual at the time of cue re-encounter. Typically, the amount of incentive salience attributed to a cue is believed to increase with the relative reliability that the cue predicts reward, where cues that consistently predict reward become powerful motivational magnets, eliciting approach and even consummatory behaviors (similar to those produced by the reward itself). In contrast, cues that predict reward with a lesser degree of certainty should theoretically be less attractive, and accrue lower levels of incentive salience. However, in some cases, cues that predict reward with maximal levels of uncertainty, such as in gambling, may generate higher levels of incentive salience attribution and become very attractive. In order to examine the impact of uncertainty, we used a Pavlovian conditioned approach task (autoshaping), where a bright noisy lever cue precedes delivery of a sucrose reward pellet. We have previously shown that a cue that predicts a reward only half the time (probability = 50%), but where the value of that reward can vary (1, 2 or 3 sucrose pellets), attracts more incentive value than a cue that systematically (probability = 100%) predicts a single sucrose reward pellet. Here we examined whether the increased incentive value attributed to uncertain cues was equally distributed across cues that were proximal (5 cm) or distal (20 cm) to the site of reward (magazine). Our results confirm that incentive value is greater for uncertain cues, and show that it is equally distributed across proximal and distal cues. In contrast, when the CS cue predicts the UCS reward with absolute certainty, incentive value is preferentially given to proximal cues, with distal cues being almost ignored. This suggests that reward uncertainty not only attributes more incentive value to cues, but that it may also act by recruiting a broader range of cues. However, since the learnt predictive value of the cue is low, this increase in incentive salience may be generated through greater mesolimbic activity driven by anticipation and/or stress of an unpredictable reward. In conclusion, reward uncertainty may transform a broad array of cues into powerful motivational magnets, which in turn could help explain what makes gambling so attractive. [less ▲]

BACKGROUND: MicroRNAs (miRNAs) are a class of small RNAs that are implicated in the control of eukaryotic gene expression by binding to the 3'UTR of target mRNAs. Several algorithms have been developed for miRNA target prediction however, experimental validation is still essential for the correct identification of miRNA targets. We have recently predicted that Neuropilin2a (Nrp2a), a vascular endothelial growth factor receptor which is essential for normal developmental angiogenesis in zebrafish, is a dre-miR-2188 target. METHODOLOGY: Here we show that dre-miR-2188 targets the 3'-untranslated region (3'UTR) of Nrp2a mRNA and is implicated in proper intersegmental vessel development in vivo. Over expression of miR-2188 in zebrafish embryos down regulates Nrp2a expression and results in intersegmental vessel disruption, while its silencing increases Nrp2a expression and intersegmental vessel sprouting. An in vivo GFP sensor assay based on a fusion between the GFP coding region and the Nrp2a 3'UTR confirms that miR-2188 binds to the 3'UTR of Nrp2a and inhibits protein translation. CONCLUSIONS: We demonstrate that miR-2188 targets Nrp2a and affects intersegmental vessel development in zebrafish embryos. [less ▲]

Objectives: The technical nature of laparoscopy, and the required specific laparoscopic tools and medical skills, may render this approach difficult in developing countries. We hypothesized that laparoscopy may be developed in the Cliniques Universitaires de Kinshasa (CUK), and may be cost-effective. The final aim of this program is to bring the benefits of laparoscopy to the DRC population, by allowance of adequate training on the UNIKIN personnel, including anaesthetists, surgeons and nurses, who in the future will have to locally form the DRC medical and nursery students. Methods: With the financial support from Wallonie-Bruxelles International (WBI), a complete CUK team, including a surgeon (2 years training in Belgium), an anaesthetist and nurses, were trained in Belgium and then afterwards in DRC. The laparoscopic equipment was sent to Kinshasa, and three theoretical and practical missions of Belgian teams were organised. Results: Over a 2 year period, 116 laparoscopic procedure were performed, including 32 appendectomies, 41 cholecystectomies, 11 hernia repairs, 9 laparoscopy explorations for peritoneal carcinoma assessment and biopsy, 8 procedures for catheter of dialysis peritoneal, 5 gynecologics procedures, and 10 other miscellaneous procedures. Conclusions: A joined approach, taking into account on one hand the training of the skills locally trained to adapt itself to some difficulties, on the other hand institutions of scientific support and a real program and local will of development of this new procedure are the wages of development, accessibility and durability of such news approach in developing countries. All University and non-University team willing to join such a project are welcome. [less ▲]

Sea ice is an active source or a sink for carbon dioxide (CO2), although to what extent is not clear. Here, we analyze CO2 dynamics within sea ice using a one-dimensional halo-thermodynamic sea ice model including gas physics and carbon biogeochemistry. The ice-ocean fluxes and vertical transport of total dissolved inorganic carbon (DIC) and total alkalinity (TA) are represented using fluid transport equations. [less ▲]
