The present study approaches the extraction of lignin samples from several lignocellulosic renewable feedstocks, including raw materials from Greece. The valorization of these lignins samples into high-added value components will also be explored using chemical catalytic routes and “green chemistry” methodology. The present study is a collaboration of Biomass Group of Aristotle University of Thessaloniki, Greece and Gembloux Agro-Bio Tech, in the frame of UBIOCHEM COST ACTION C0903, performed at the Laboratories of Biological and Industrial Chemistry Unit, Gembloux Agro-Bio Tech, University of Liege with samples preparation at AUTh. The lignin extraction from lignocellulosic biomass takes place via chemical, thermal and mechanical routes, including acid or basic processes, steam cracking, steam explosion. Statistical approaches (i.e. response surface methodology) are used for the optimization of processing parameters. Physico-chemical characterization of lignin materials is considered using specific techniques developed by the research team of Agro-Bio-Tech Institute, including qualitative and quantitative mono- and bidimensionnal NMR spectroscopy, MALLS, FT-IR, TGA and chemical methods. The characterization of the lignocellulosic materials before and after pretreatment protocol is investigated regarding the determination of extractives, ash, total lignin contents, and structural carbohydrates as well as proteins contents. Chemical catalytic routes and “green chemistry” methodology is conducted in order to valorize lignin. [less ▲]

The presence in Corsica of a field mouse is well known. Several authors have noted some of its morphological peculiarities but it was only recently (1980) that the presence of A. sylvaticus was establblished with certainty. However, this evidence is based on a check of a limited number of individuals originating from a single locality. In order to generalize these observations, we performed o biochemical test on six Corsican mice caught in three distinct localites and a morpho biometrical study of 491 skulls. The results show that A. sylvaticus is spread all over the island and that A. flavicollis is probably absent. No sexual dimorphism was found but strong spatial variations in the cranial measurements were ividenced. There are far less important between the various Corsican sub samples than between the insular and the continenecal mice. The evolutionary and adaptive significance of the increase in size of insular mice is discussed in relation to the theory of island biogeography and to the present knowledge on the history of the mammalian settlement of the island.

The vacuum UV photoabsorption spectrum of CH3I has been investigated between 5 and 20 eV. Numerous vibronic transitions are observed. In the high 10-20 eV photon energy range weak to very weak diffuse bands are observed and ascribed to electronic transitions from 3a1, 1e and 2a1 to Rydberg orbitals. In the 6-10.5 eV photon energy range more than 200 sharp and strong to weak lines have been observed. Several photon energy ranges were explored under high resolution conditions allowing us to observe many series up to high values of the principal quantum number n. They are assigned to vibrationless Rydberg transitions and classified into two groups converging to the two components of the spin-orbit split 2E state of CH3I+. These two groups consist of six different Rydberg series, i.e., nsa1, npa1, npe, nda1, nde and nf. A very close correlation has been established between the term values of the Rydberg states in CH3I and in Xe for ns, np, nd and nf Rydberg transitions. For the first time, the same measurements have been performed and the interpretation has been proposed for the photoabsorption spectrum of CH2DI and CD3I in the 6-10.5 eV photon energy range. For these two species, ionization energies are deduced: for the 2E3/2 and 2E1/2 states of CH2DI, these are IEad=9.544 eV and IEad=10.168 eV respectively and the corresponding energies are 9.552 eV and 10.173 eV in CD3I.

To regenerate adventitious shoots from the cotyledon proximal parts of Citrullus lanatus (Thunb.) Matsum. and Nakai ssp. mucosospermus (Fursa) oleaginous type, different concentrations of MS mineral elements, sucrose, 6-benzylaminopurine (BAP) and agar were tested. Shoot induction proved to depend on the interaction between levels of sucrose, BAP and MS mineral elements in the medium. The medium containing 3/2 strength of MS mineral elements, 35 g/l sucrose and 1 mg/l BAP solidified with 6 g/l agar allowed the production of numerous shoots without a callus phase. After 3 weeks of culture, 76.7% of the cotyledon proximal parts induced shoots with an average of 12.26 shoots per explant and a mean shoot length of 17.13 mm. The induced shoots were directly rooted and thus complete plants ready for acclimatization were obtained using a two steps procedure. Depending on the genotype, the shoot induction from cotyledon proximal parts ranged from 54% to 96%. Rooted plantlets were acclimatized and transferred to field, where they grew well, developed flowers and fruits like seeded plants. The assessment of the genetic stability of the in-vitro-regenerated plantlets by means of an Amplified Fragment Length Polymorphism (AFLP) analysis with the combination of 5 primers revealed no differences between regenerated plantlets and mother plants.

Size of methyl ricinoleate droplets during biotransformation into γ-decalactone by Yarrowia lipolytica was measured in both homogenized and non-homogenized media. In non-homogenized but shaken medium, droplets had an average volume surface diameter d 32 of 2.5 μm whereas it was 0.7 μm in homogenized and shaken medium. But as soon as yeast cells were inoculated, both diameters became similar at about 0.7 μm and did not vary significantly until the end of the culture. The growth of Y. lipolytica in both media was very similar except for the lag phase which was lowered in homogenized medium conditions. [less ▲]

The authors present 50 cases of cervical spondylotic myelopathy treated by anterior or posterior approach. To assess the severity of the pre- and postoperative neurological symptoms, they define an original ten-point classification scale taking into account gait and urinary disturbance, ability to manipulate objects and pain. With C2-C7 laminectomy, 60% of the patients are improved, essentially for walk. A few cases only (14%) are upgraded for upper limbs function. The authors conclude that this surgical treatment should be applied only when there is a multi-level narrowed canal and predominant lower limbs deficits. The efficacy of the anterior approach depends on complete removal of osteophytes. In cases with complete osteophytectomy, this surgical treatment can improve both the upper and lower limbs function and 77.8% good results are obtained. In a few cases it may be necessary to use both approach successively. Discriminant analysis applied to 12 factors shows that pre-operative scores of upper and lower limbs and sagittal diameter of spinal canal are the most important factors for neurological prognosis.

Dans ce chapitre, Sébastien Brunet et Frédéric Claisse proposent un retour critique sur Meeting of Minds, expérience hors du commun de conférence de citoyens sur les neurosciences, qui aura conjugué les efforts de 126 citoyens européens et l’expérience d’une dizaine d’instituts d’évaluation technologique, réunis à l’initiative de la Fondation Roi Baudouin et avec le soutien de la Commission europénne. Processus complexe et multi-dimensionnel, Meeting of Minds s’est finalement moins heurté aux difficultés pratiques et logistiques de la participation à échelle internationale (dans l’ensemble bien anticipées), qu’à ses propres ambivalences et contradictions. En revenant sur un épisode particulièrement emblématique de la deuxième convention européenne qui marquait le point culminant du processus, les auteurs mettent en évidence les tensions qui résultaient, d’une part, de l’ambivalence de l’expertise accordée aux citoyens et, d’autre part, de la focalisation excessive sur une méthodologie participative devenue par moments à elle-même sa propre fin. Le chapitre illustre ainsi les impasses de ce que les auteurs appellent une conception « performative » de la participation, caractérisée par l’indifférence à la production concrète des participants, dont la principale qualité est en réalité d’avoir été performée par le dispositif. Au lieu de servir d’outil d’exploration de controverse et de source d’enrichissement du processus de décision (dont Meeting of Minds était d’ailleurs déconnecté), la conférence de citoyens a paradoxalement fini par faire passer les neurosciences à l’arrière-plan pour ne plus « fabriquer » que du dispositif et de la participation.

Parenting support has been placed on the political agenda in Europe for the last decade (OECD, 2008, 2009 ; Eurofund, 2011). But a close look to the major discourse can reveal that the interest is very often linked to a compensatory vision of a so-called « deficiency » on behalf of some parents (social control). The symposium has proposed to explore the notion of « meeting places for children and parents » : their characteristics, the driven goals, the values shared by professionals . These places where parents can share « hic et nunc » their own experiences and expertise as parents (not in a preventive purpose) are considered as possible ways of questioning the compensatory approach. Characteristics of meeting places as learning communities have been displayed through a presentation of inspiring practices from different contexts: Italy, Flanders and Federation Wallonia-Brussels. Informal social networks among parents and children are an important source of parental support. Meeting places are settings where such informal networks and social cohesion are facilitated among families with diverse backgrounds. The staff (both professionals and volunteers) plays an important role in facilitating the informal contacts between parents and children. Their role as a “host” (instead of being pedagogical experts) demands specific individual competences and systemic conditions. [less ▲]

Objective: The objective was to create a new measure of everyday life functioning by developing a computerized real-life activity task where participants are asked to prepare a room for a meeting. Background: Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia. However, everyday life functioning is usually evaluated with questionnaires, performance-based or observation assessments, all of which contain a number of limits. Method: Twenty-one individuals diagnosed with schizophrenia and 21 matched healthy controls completed the computerized meeting preparation task. Patients were also evaluated with an extensive cognitive battery and several measures of symptomatology and everyday life functioning. Results: Results showed that performance on the computerized task significantly differentiated patients and controls for a certain number of variables. These variables, summarized in a global score, were significantly correlated with both cognitive and everyday life functioning. Moreover, this composite score significantly predicted 39% of everyday life functioning, whereas a cognitive composite score only predicted 22%. In addition, when the meeting task composite score was combined with symptomatology and the cognitive composite score, these measures significantly predicted up to 73% of everyday life functioning. Conclusion: The findings suggest that the meeting preparation task provides a good indication of the level of everyday life functioning in patients with schizophrenia, and may be viewed as a valuable instrument in both an evaluation and remediation context.
