Production and purification of hydrophobin HFBII has recently been the subject of intensive research, but the yield of production needs to be further improved for a generic use of this molecule at industrial scale. In a first step, the influence of different carbon sources on the growth of Trichoderma reesei and the production of HFBII was investigated. The optimum productivity was obtained by using 40 g/L lactose. Carbon starvation and excretion of extracellular enzyme were determined as two main conditions for the production of HFBII. In the second phase, and according to the physiological mechanisms observed during the screening phase, a bioreactor set up has been designed and two modes of cultures have been investigated, i.e. the classical submerged fermentation and a fungal biofilm reactor. In this last set-up, the broth is continuously recirculated on a metal packing exhibiting a high specific surface. In this case, the fungal biomass was mainly attached to the metal packing, leading to a simplification of downstream processing scheme. More importantly, the HFBII concentration increased up to 48.6 ± 6.2 mg/L which was 1.8 times higher in this reactor configuration and faster than the submerged culture. X-ray tomography analysis shows that the biofilm overgrowth occurs when successive cultures are performed on the same packing. However, this phenomenon has no significant influence on the yield of HFBII, suggesting that this process could be operated in continuous mode. Protein hydrolysis during stationary phase was observed by MALDI-TOF analysis according to the removal of the last amino acid from the structure of HFBII after 48 h from the beginning of fermentation in biofilm reactor. Hopefully this modification does not lead to alternation of the main physicochemical properties of HFBII. [less ▲]

La figure de la déesse Héra est étroitement liée au pouvoir de Zeus, et par là même à la configuration grecque de la souveraineté. Dans sa figure de déesse en colère, Héra met en œuvre la « querelle » (éris) structurante, autrement dit elle est l’« ennemie intime » nécessaire à une bonne gestion du pouvoir. Mais la figure de l’épouse est tout aussi présente et cruciale, dans la représentation grecque de la déesse. C’est en cumulant les statuts de sœur et d’épouse qu’Héra assoit son rôle de souveraine, une souveraine dont le rang n’est pas toutefois absolu, mais relatif à celui du dieu qu’elle côtoie. [less ▲]

Partant de quelques textes dans lesquels S. Kracauer traite du rapport entre montage et réel, cet article tente de préciser et de problématiser l’ambivalence de Kracauer à l’égard de l’outil « montage », notamment dans le champ cinématographique, en ouvrant la réflexion par cette double question : comment définir un « mauvais usage » du montage et, à l’opposé, comment peuvent se mettre en place les conditions d’un « bon usage » du montage selon Kracauer ? Pour y répondre, les auteurs identifient d'abord, dans l’œuvre de Kracauer, les éléments explicites et implicites (montage textuel) qui permettent de saisir au plus près ce que serait, selon le philosophe et sociologue, le principe de réalité. Ensuite, une œuvre photographique, contemporaine des quelques textes évoqués, Menschen des 20. Jahrhunderts d’August Sander, permet de mieux circonscrire les possibles concrétisations de cette pensée en la mettant à l’épreuve d’une réalisation en images et en montage. [less ▲]

Intra-luminal fluid and excessive abnormal hyper-edema are regularly used for the diagnosis of endometritis in the mare, which is routinely confirmed by the presence of neutrophils on endometrial smears. Studies show a relation between neutrophils and myeloperoxidase (MPO), an enzyme contained in and released by neutrophils during degranulation or after cell lysis. This enzyme has been found in many fluids and tissues and associated with different inflammatory pathologies in the horse. The aims of this study were to assess the presence and concentration of MPO in the equine uterus, and to investigate its relation with neutrophils, and other clinical signs of endometritis. Mares (n=51) were evaluated for presence of intra-luminal fluid and excessive endometrial edema before breeding, and a small volume lavage and cytology samples were obtained. From 69 cycles, supernatant of the uterine flushes was analysed with a specific equine MPO ELISA assay to measure MPO concentration. Cytology samples were used for the diagnosis of endometritis. MPO was present in the uterus of all estrus mares in highly variable concentrations. MPO concentrations were significantly (p<0.05) higher in samples with positive cytologies and in presence of intra-luminal fluid. Occasionally, some samples with negative cytologies showed high MPO concentration, but the opposite was never observed. Cycles presenting hyper-edema weren’t associated to high concentration of MPO, intra-luminal fluid or positive cytology making it a poor diagnostic tool of endometritis. [less ▲]

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]

G-protein-coupled receptors (GPCRs) constitute the largest family of transmembrane proteins. Although implicated in almost all physiological processes in the human body, most of them remain unexploited, mostly because of the lack of specific ligands. The objective of this work is to develop a new mass-spectrometry-based technique capable of identifying new peptide ligands for GPCRs. The strategy is based on the incubation of cellular membranes overexpressing GPCRs with a mixture of peptides that contains potential ligands. Peptide ligands bind to the receptors, whereas other peptides remain in the binding buffer. Bound peptides are eluted from membranes and directly detected, identified, and characterized by MALDI TOF–TOF. The results reveal the efficacy of the procedure for selecting a specific ligand of GPCRs in both simple and complex mixtures of peptides. This new approach may offer direct purification, identification, and characterization of the new ligand in a single workflow. The proposed method is labeling-free and, unlike radio-binding and other techniques, it does not require a previously known labeled ligand of the studied GPCR. All these properties greatly reduce the experimental constraints. Moreover, because it is not based on the principle of a competitive specific binding, this technique constitutes a new tool to discover new ligands not only for known GPCRs, but also for orphan GPCRs [less ▲]

This paper deals with adnominal possession in Ancient Egyptian, focusing on constructions involving a pronominal possessor. In early Egyptian, a single construction is attested: substantive (possessee) + bound person marker (possessor). From the 6th Dynasty onwards, a new construction, which is built from a demonstrative determiner, appears: pAy + bound person marker (possessor) + substantive (possessee). In order to describe the gradual encroachment of the innovative possessive determiner pAy-f on the older construction with the possessive bound person marker, this study proposes a discourse-oriented analysis, using the notion of ‘subjective deixis.’ [less ▲]

L’argument de ce XLème Colloque des Hôpitaux de jour psychiatriques nous a plongés dans un abîme de questionnements théoriques et pratiques. Défiés par cette immersion dans les tréfonds du modèle, nous avons choisi de nous accrocher aux fondements de notre univers. La mythologie grecque sera donc notre source d’inspiration en mettant un dieu antique à notre disposition. Chronos sera notre guide dans un périple réflexif soumettant nos théories et notre pratique à l’épreuve du temps. Le récit de la conception d’un atelier thérapeutique, l’atelier « Art & Temps », sera notre fil d’Ariane dans notre tentative de symboliser notre pratique thérapeutique quotidienne et ses enjeux. Par la suite, l’exposé d’un cas clinique concrétisera un raisonnement théorique visant à situer notre modèle de prise en charge dans le réseau psychiatrique global. [less ▲]
