Rwanda. Through us, humanity (2005), a movie by Marie-France Collard, follows on from the play Rwanda 94, a project in which she tool part as a author and videographer. Showcased in 2000, the play arises questions about memory, representation, and commitment. The documentary was carried out during artist collective Groupov's tour in Kigaly on the occasion of the commemoration of the genocide's tenth anniversary. It brings those topics up again, gets back to the reception of the play by the Rwandan audience and, in a broader way, to a country in mourning. [less ▲]

Introduction: A 3-year-old Landrace boar with a bilateral swelling of the scrotum was submitted to the Swine clinic in August. History reported a period of hyperthermia, anorexia, depression and weight loss in May. Recovery was obtained after a treatment based on antibiotic (lincomycin and ceftiofur) and anti-inflammatory (steroid) medication injections. On July, the boar fell down after a supervised natural mating. Materials and Methods: The present poster describes our clinical approach and conclusions. Results: The boar had a good general condition and a normal appetite. Scrotal palpation was painless. The left hemiscrotum was more enlarged than the right one. Serological analysis allowed to exclude Aujeszky disease virus, Brucella suis and Chlamydia spp., the main agents responsible for orchitis in pigs. Ultrasonography revealed multiple hypoechogenic cavities around both testicles. Semen analysis performed using microscope showed azoospermia. Dissection of the scrotal tissues - performed in October - revealed the presence of kystic structures filled with serous fluid; the largest one had a diameter of approximately 15 cm. These kystic structures were surrounded by an abondant fibrous connective tissue. Histological examination showed the presence of large amount of lymphocytes and hemosiderophages around the kysts. No sign of spermatogenesis was detected in testis. An hyperplasia of the interstitial tissue in detriment to seminiferous tubules was also observed. Conclusion: These results led us to confirm the traumatic origin of the bilateral scrotal swelling observed in this boar. The lesions were the result of a partial resorption of a complex extratesticular hematoma. [less ▲]

We study one-loop radiative neutrino mass models in which one of the beyond-the- standard model fi elds is either a hypercharge-zero fermion quintet (minimal dark matter) or a hypercharge-zero scalar septet. By systematically classifying all possible one-loop such models we identify various processes that render the neutral component of these representations (dark matter) cosmologically unstable. Thus, our fi ndings show that these scenarios are in general not reconcilable with dark matter stability unless tiny couplings or additional ad hoc symmetries are assumed, in contrast to minimal dark matter models where stability is entirely due to the standard model gauge symmetry. For some variants based on higher-order loops we find that alpha_ 2 reaches a Landau pole at rather low scales, a couple orders of magnitude from the characteristic scale of the model itself. Thus, we argue that some of these variations although consistent with dark matter stability and phenomenological constraints are hard to reconcile with perturbativity criteria. [less ▲]

Analogical reasoning development maintains a mutual influence with language acquisition: the use of relational labels helps to resolve analogical reasoning tasks (Christie & Gentner, 2014) while analogical reasoning enables the acquisition of new linguistic concepts or structures (Gentner & Namy, 2006). This link has driven some authors to examine the analogical reasoning ability of children with Specific Language Impairment. Those children have poorer analogical reasoning performance than their age-matched peers without language disorders (Leroy et al., 2012 ; Leroy et al., 2014). So, children with SLI seem to have an analogical reasoning weakness which could be linked to their language disorders. Thus, our goal here is to measure the ability of children with SLI to solve analogies, and to compare it to chronological age-matched but also to linguistic age-matched peers without language disorders. Our hypotheses here are the followings: children with SLI have weaker analogical reasoning competence compared to chronological age-matched peers and similar or weaker analogical reasoning competence compared to language-matched peers. To test these hypotheses, we use a scene analogy task composed of pictures of 20 relations (Richland et al., 2006) varying in relational complexity (binary or ternary relations) and in perceptual distraction. Twenty children with SLI are matched to chronological age and linguistic age peers without language disorders. Children with SLI have poorer performance then their age-matched peers but they have similar performance to their language-matched peers. This data reinforces the idea of a link between analogical reasoning and language, also in children with SLI. However, the nature of this link should still be clarified. [less ▲]

The glucosinolate profiles, phenol and flavonoid contents and the antioxidant activity of Eruca vesicaria longirostris were studied for different organs and origins. Eleven desulpho-glucosinolates (DS-GLSs) were isolated and quantified by lipid chromatography- DAD. Similarity between profiles was obtained. Total DS-GLS content, expressed as sinigrin equivalents (SE) revealed a certain variabilily ranging between (76.07-45.61), (27.01-13.53), (4.52 -18.01), (9.39-3.37) and (1.16-13.99) μmol /g DW for seeds, flowers, leaves, roots and stems, respectively.

Introduction: Indoleamine 2,3-dioxygenase (IDO) catalyzes the initial step in the catabolism of L-tryptophan along the kynurenine pathway and exerts immunosuppressive properties in inflammatory and tumor tissues by blocking locally T-lymphocyte proliferation. Recently, 1-(2-[19F]fluoroethyl)-DL-tryptophan (1-[19F]FE-DL-Trp) was reported as a good and specific substrate of this enzyme. Herein, the radiosynthesis of its radioactive isotopomer (1-[18F]FE-DL-Trp, DL-[18F]5) is presented along with in vitro enzymatic and cellular uptake studies. Methods: The one-pot n.c.a. radiosynthesis of this novel potential PET imaging tracer, including HPLC purification and formulation, has been fully automated on a FASTlabTM synthesizer. Chiral separation of both isomers and their formulation were implemented on a second cassette. In vitro enzymatic and cellular uptake studies were then conducted with the D-, L- and DL-radiotracers. Results: The radiolabeling of the tosylate precursor was performed in DMF (in 5 min; RCY: 57% (d.c.), n=3). After hydrolysis, HPLC purification and formulation, DL-[18F]5 was obtained with a global radiochemical yield of 18±3% (not decay corrected, n=7, in 80 min) and a specific activity of 600±180 GBq/µmol (n=5). The subsequent separation of L- and D-enantiomers was performed by chiral HPLC and both were obtained after formulation with a RCY (d.c.) of 6.1% and 5.8%, respectively. In vitro enzymatic assays reveal that L-[18F]5 is a better substrate than D-[18F]5 for human IDO. In vitro cellular assays show an IDO-specific uptake of the racemate varying from 30% to 50% of that of L-[18F]5, and a negligible uptake of D-[18F]5. Conclusion: In vitro studies show that L-[18F]5 is a good and specific substrate of hIDO, while presenting a very low efflux. These results confirm that L-[18F]5 could be a very useful PET radiotracer for IDO expressing cells in cancer imaging. [less ▲]
