Precise brain regions are activated when a subject gives a judgment on himself. Those are the medial parietal cortex, essentially related to episodic memory processing, and the ventromedial prefrontal cortex, recruited for evaluating the personal valence of an information. These regions are not activated in Alzheimer's disease. The decrease of awareness for own deficits in a patient with Alzheimer's disease would depend on a reduction of episodic memory capacities and a worsening of judgment for self significance. [less ▲]

European nitrate directive (CEE/91/676) imposes wide monitoring of Nitrogen in farmlands. The Walloon Region (South of Belgium – 750 000 ha of arable land) develops an original combination of methods to reach European objectives in this topic. On the one hand, water and nitrogen flows and balances are modelled, on the other hand, an Agricultural Surface Survey is put into practice to monitor nitrate nitrogen in the soil at the beginning of the leaching period. The Agricultural Surface Survey is constituted by a 30 reference farms network within more than 200 plots are monitored each in order to fix annual standards for nitrate profiles. Each year, about 1% of the Walloon farms are assessed about their good nitrogen management. Thanks to the existence of a useful database of nitrate profiles measured through six years in the whole Walloon Region, validation of the simulations in the vadose zone can be realised. The comparison of the measured data and the simulation shows a good accuracy of the EPICgrid model. [less ▲]

The timing of the last deglaciation in southern Chile is re-evaluated from a calendar varve chronology (Lago Puyehue, 40 degrees S). The climate shifts are analysed by continuous annual varve-thickness measurements through the similar to 17,100 cal. year to 10,800 cal. year BP time window (similar to 3.5 m sediment core). The varve years are determined by the alternation of light (phytoplankton-rich) and dark (terrigenous and organic-rich) layers forming graded annual couplets (similar to 0.2 to 0.8 mm/year). The varve chronology is constructed by conventional varve-counting methods on thin sections after correction for instantaneous volcanic and/or seismic events detected in the thin sections. The calibrated varve-age model derived from the manual varve counting is constrained by high-resolution grey-scale (GS) semi-automatic counts of the annual light phytoplankton-rich layers (similar to 120 mu m to 300 mu m thick). Due to physical sediment properties the GS constitutes a proxy record for the phytoplankton/terrigenous varve-thickness variations through the sediment record. The varve couplets are thicker/thinner during humid/dry phases and darker/lighter (negative/positive annual grey-scale index) during cold/warm phases. Our results show that at 40 degrees S the last deglaciation took place in two phases between similar to 17,100 cal. year and similar to 15,500 cal. year BP. We note a climate instability between similar to 15,500 cal. year and 13,300 cal. year BP and a significant dry phase between similar to 15,000 and 14,500 cal. year BP. We evidence a cold event in two phases between similar to 13,300 and 12,200 cal. year BP interrupted by a dry event between similar to 12,800 and 12,600 cal. year BP. The onset of a significant warmer period is observed after similar to 11,500 cal. year BP. Our results provide new evidence of a Younger Dryas cool reversal in southern Chile, i.e., the Huelmo/Mascardi event Hajdas et al. (2003) associated with an abrupt dry pulse at similar to 12,800-12,600 cal. year BP. The high-resolution grey-scale measurements performed on the biogenic varves from Lago Puyehue provide a reliable calibrated chronology of the regional environmental and climate shifts during the last deglaciation.

Acne benefits from a series of treatments. The introduction of isotretinoin was a therapeutic breakthrough which considerably improved both the evolution and the prognosis of the disease. Indications of this retinoid kept changing over the past twenty years. New clinical conditions emerged including the management of disease recurrences. The daily dosages must be selected according to the type of acne, the gender of the patient and the pharmaco-economical implications. Teratogenicity must never be neglected as it represents the dreadful adverse event of the drug. A European Directive currently marks out the way to use this retinoid. [less ▲]

Aims: The potential use of bifidobacteria as indicators for faecal contamination was studied along a sheep meat production and processing chain. The levels of bifidobacteria were compared with those of Escherichia coli. Total viable counts were followed along the chain (244 samples). Methods and Results: Forty-three per cent of the samples contained bifidobacteria, of which 15% were solely detected using a PCR method based on the hsp60 gene and not by a culture-based method. Bifidobacteria were detected in only three of nine sheep faeces samples using one or the other method. However, carcasses (types C and E) were highly contaminated. These sample types (30% and 28%, respectively) were positive for bifidobacteria and negative for E. coli. The species Bifidobacterium pseudolongum and Bif. thermophilum, isolated from faecal samples, were predominant. Bifidobacterium choerinum were found in C, D, E and F sample types. Conclusions: Bifidobacteria were shown more efficient than E. coli in carcasses samples. The presence of Bif. choerinum suggested a faecal pork contamination. Significance and Impact of the Study: Detection and identification of bifidobacteria, in correlation with E. coli counting, should improve hygiene quality of mutton processing chains. [less ▲]

Perfluorooctane sulfonate (PFOS) and other perfluoroalkyl compounds (PFCs) were measured in liver samples from 29 marine tucuxi dolphins from Rio de Janeiro state (RJ), Brazil. PFC measurement combined liquid chromatography and mass spectrometry, using a CapLC system connected to a Quadrupole- LIT mass spectrometer. PFOS was the only PFC detected and it was so in all samples. PFOS concentrations (ng ·g-1 dw) of dolphins (n)23) from the highly contaminated Guanabara Bay (in RJ) varied between 43 and 2431 as well as between 76 and 427 from areas of RJ other than the quoted bay (n ) 6). Concentrations of three fetuses and one neonate varied between 664 and 1590. Fetus/mother ratios were calculated in two situations (2.75 and 2.62). It seems that mother-to-calf transference plays important role for relationships between PFOS and age. When a one-year-old male calf presenting 2431 ng ·g-1 dw was excluded from the test, significant correlations were observed between PFOS concentrations and both age and total length. Despite the placental transference, PFOS concentrations were not significantly lower in females than in males. PFOS levels in marine tucuxi dolphins from Guanabara Bay are among the highest detected to date in cetaceans, andthismayrepresentathreat to the small population concerned. [less ▲]

REPERE n’est pas une publication très ancienne, puisqu’elle a été créée en 2003 sous sa forme électronique, et est sortie pour la première fois en 2005 sous forme papier. Et pourtant, à l’aune du temps de l’Internet, une refonte de ses contenus était en grande partie nécessaire. En effet, ces dernières années ont vu de nombreuses évolutions, qui, sans révolutionner la recherche documentaire, l’ont modifié, en particulier pour les ressources électroniques. Ainsi, si Google fête à peine ses 10 ans en septembre 2008, cette décennie a été celle de son ascension, proposant sans cesse de nouvelles fonctionnalités, parfois discrètes. Google book search a, à une époque, fait couler beaucoup d’encre, mais Google Scholar, dans l’ombre du géant, prenait une place peut-être plus dangereuse, en tout cas en ce qui concerne la recherche d’information scientifique. De nos jours, la recherche d’information ne peut plus se penser sans Google, même si Google doit être dépassé et ne peut rester l’unique outil. Le web 2.0, terme certes galvaudé, reflète aussi une autre évolution de l’Internet, dans ce qu’il renforce l’aspect collaboratif et participatif de tous les internautes. La production d’information a changé, ainsi que son accès, et donc sa recherche. Les professionnels de l’information ont très vite intégré ces changements dans leurs formations, à travers les supports pédagogiques proposés par les URFIST et les Services communs de la documentation, ainsi que par les nombreuses formations dispensées. La notion d’éducation à l’information, de culture informationnelle est maintenant répandue au-delà de la simple sphère bibliothéconomique. Aussi, cette nouvelle version de REPERE reflète ces évolutions, et intègre de nouveaux outils. Certains chapitres ont été juste actualisés, d’autres complètement refondus, enfin de nouvelles parties ont été ajoutées, sur le besoin d’information ou le plagiat, pour ne pas les citer toutes. Nous espérons que cette brochure réactualisée saura être une première réponse à grands nombres de vos questions. N’hésitez pas à nous faire part de vos remarques, à nous signaler comment vous utilisez cette brochure et si elle répond à vos besoins. Nous en tiendrons compte pour la prochaine version. [less ▲]
