We review the interest of cognitive event-related potentials (ERPs) in comatose, vegetative, or minimally conscious patients. Auditory cognitive ERPs are useful to investigate residual cognitive functions, such as echoic memory (MMN), acoustical and semantic discrimination (P300), and incongruent language detection (N400). While early ERPs (such as the absence of cortical responses on somatosensory-evoked potentials) predict bad outcome, cognitive ERPs (MMN and P300) are indicative of recovery of consciousness. In coma-survivors, cognitive potentials are more frequently obtained when using stimuli that are more ecologic or have an emotional content (such as the patient's own name) than when using classical sine tones.

BACKGROUND: Thiamine triphosphate (ThTP) exists in most organisms and might play a role in cellular stress responses. In E. coli, ThTP is accumulated in response to amino acid starvation but the mechanism of its synthesis is still a matter of controversy. It has been suggested that ThTP is synthesized by an ATP-dependent specific thiamine diphosphate kinase. However, it is also known that vertebrate adenylate kinase 1 catalyzes ThTP synthesis at a very low rate and it has been postulated that this enzyme is responsible for ThTP synthesis in vivo. RESULTS: Here we show that bacterial, as vertebrate adenylate kinases are able to catalyze ThTP synthesis, but at a rate more than 106-fold lower than ATP synthesis. This activity is too low to explain the high rate of ThTP accumulation observed in E. coli during amino acid starvation. Moreover, bacteria from the heat-sensitive CV2 strain accumulate high amounts of ThTP (>50% of total thiamine) at 37 degrees C despite complete inactivation of adenylate kinase and a subsequent drop in cellular ATP. CONCLUSION: These results clearly demonstrate that adenylate kinase is not responsible for ThTP synthesis in vivo. Furthermore, they show that E. coli accumulate large amounts of ThTP under severe energy stress when ATP levels are very low, an observation not in favor of an ATP-dependent mechanisms for ThTP synthesis.

The purpose of the present study was to assess if AVP-neurophysin is associated with hypercortisolemia and suicidal behaviour in depressed patients. The study included 28 patients subgrouped into suicide attempters (n=13) and nonattempters (n=15). We assessed basal AVP-neurophysins concentrations and post-dexamethasone (DST) cortisol levels. Concentrations of AVP-neurophysins did not differ between DST suppressors and nonsuppressors: 0.29+/-0.13ng/ml vs 0.36+/-0.21ng/ml, (F=1.1, df=1, 27, p=0.30). Suicide attempters did not differ from nonattempters for AVP-neurophysins levels. Our results fail to support a role of AVP in the early cortisol escape. [less ▲]

a justice est longtemps apparue comme l’affaire de l’Etat et des professionnels du droit. Depuis une vingtaine d’années, ces derniers ont dû composer avec l’arrivée de nouveaux acteurs alors même que les attentes adressées à l’appareil judiciaire, ainsi que ses fonctions, étaient appelées à se redéfinir. Nous proposons ici d’analyser certaines recompositions normatives à l’œuvre dans le champ judiciaire ainsi que certaines transformations organisationnelles, notamment dans les interactions entre les acteurs de la justice.

This article discusses the application of partial least squares (PLS) for monitoring complex chemical systems. In relation to existing work, this article proposes the integration of the statistical local approach into the PLS framework to monitor changes in the underlying model rather than analyzing the recorded input/output data directly. As discussed in the literature, monitoring changes in model parameters addresses the problems of nonstationary behavior and presents an analogy to model-based approaches. The benefits of the proposed technique are that (i) a detailed mechanistic plant model is not required, (ii) nonstationary process behavior does not produce false alarms, (iii) parameter changes can be non-Gaussian, (iv) Gaussian monitoring statistics can be established to simplify the monitoring task, and (v) fault magnitude and signatures can be estimated. This is demonstrated by a simulation example and the analysis of recorded data from two chemical processes. [less ▲]

Purpose – Fair trade organisations (FTOs) have been taken quite early as examples of Social Enterprises (SE) and have contributed to the shaping of the SE concept. The purpose of this paper is to examine more deeply the link between FTOs and SE, both at a conceptual and at an empirical level. Design/methodology/approach – First, different theoretical frameworks of SE are introduced and confront FT to each of these frameworks. The second step is an empirical study of FTOs across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTOs. Findings – All the FTOs combine in some way economic, social and sometimes also political goals. FTOs are thus coherent to the “hybrid goals” nature of SEs. FTOs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTOs are closer to the European – participatory – approach while others are closer to US – individual – approaches. Finally, the governance structures of FTOs seem to reflect quite well their goal mix. Research limitations/implications – This paper provides a more solid basis for the often implicit link between FT and SE. Future researches could use this work to explore specific topics of the SE literature in the context of FT (e.g. stakeholders' involvement). The FT example could also be used to examine further the shifting boundaries of the SE reality. Originality/value – The originality of this paper is to apply the SE concept to a specific field and to show how, within this field, there is at the same time a diversity of organisations, reflecting the diversity of SE approaches; and a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations.

Despite the superficial localization of most dermatophytosis, host-fungus relationship in these infections is complex and still poorly elucidated. Though many efforts have been accomplished to characterize secreted dermatophytic proteases at the molecular level, only punctual insights have been afforded into other aspects of the pathogenesis of dermatophytosis, such as fungal adhesion, regulation of gene expression during the infection process, and immunomodulation by fungal factors. However, new genetic tools were recently developed, allowing a more rapid and high-throughput functional investigation of dermatophyte genes and the identification of new putative virulence factors. In addition, sophisticated in vitro infection models are now used and will open the way to a more comprehensive view of the interactions between these fungi and host epidermal cells, especially keratinocytes.

With the combination of the enhanced assumed strain (EAS) and assumed natural strain (ANS) techniques in the removal of shear and volumetric locking, the solid-shell formulation requires a minimum set of enhanced modes, and this results in a competitive approach when compared with other fully EAS solid elements in terms of computational costs. Moreover, the latter reportedly suffers difficulties when dealing with very thin plate and shell structures due to the severe transverse shear locking. The paper presents an alternative solid-shell formulation, in which the ANS technique is applied to the upper and lower surfaces instead of at the mid-surface of the solid-shell element as previously adopted. The numerical results show the accuracy and efficiency of the proposed technique. [less ▲]

The role of insect saliva in the first contact between an insect and a plant is crucial during feeding. Some elicitors, particularly in insect regurgitants, have been identified as inducing plant defence reactions. Here, we focused on the salivary proteome of the green peach aphid, Myzus persicae. Proteins were either directly in-solution digested or were separated by 2D SDS-PAGE before trypsin digestion. Resulting peptides were then identified by mass spectrometry coupled with database investigations. A homemade database was constituted of expressed sequence tags from the pea aphid Acyrtosiphon pisum and M. persicae. The databases were used to identify proteins related to M. persicae with a nonsequenced genome. This procedure enabled us to discover glucose oxidase, glucose dehydrogenase, NADH dehydrogenase, alpha-glucosidase and alpha-amylase in M. persicae saliva. The presence of these enzymes is discussed in terms of plant-aphid interactions. [less ▲]
