In this prospective study of 50 patients, 36 of whom developed the adult respiratory distress syndrome (ARDS), early and intense complement activation was demonstrated. These patients were at risk of the ARDS because of multiple injuries, major abdominal surgery, acute pancreatitis, severe burns, or disseminated intravascular coagulation. Abnormal C3 consumption (as measured by the C3d/C3 ratio) and elevated plasma C5a-like activity (as measured by a leukocyte aggregation assay) were associated with, respectively, 84 and 86% of cases of ARDS. Both tests were more sensitive indicators of complement consumption than were assays of total hemolytic complement activity (CH50) or total C3. The C3d/C3 ratio showed a close, inverse correlation with CH50 in 47 healthy subjects, and was increased in 12 control patients after minor surgery. The C5a-like activity was found only in patients at risk of ARDS; it was highly associated with clinical conditions that predispose to the ARDS, but it cannot be considered as a real predictor of ARDS occurrence in these patients. Sequential samples from both sides of the pulmonary circulation showed initial pulmonary clearance followed by the release of C5a-like activity. No simultaneous changes in C3 levels were found, suggesting the possible presence of modulating factors. These observations suggest that other factors (e.g., hypoxia and metabolic cascades) may influence the development of ARDS. [less ▲]

The 4M-µpump project attempts to breach the gap between traditional mechanics and micro mechanics and this in two ways. The first one consists in producing a general set of rules suitable for the miniaturisation of well-known macromachines. The second one consists in developing this fundamental aspect of the research through the design and realization of an implantable pump dedicated to the administration of medication agents inside the human body. The project thus touches upon the field of design, manufacturing, metrology and assembly of mini components as well as the study of minimotors. [less ▲]

Grâce à l’analyse statistique discursive d’un corpus constitué du discours de 90 enfants, nous avons pu observer l’évolution de l’utilisation des pronoms personnels moi et je et mettre en évidence certaines variations d’utilisation en fonction de l’âge et de trois conditions d’enregistrement. Le protocole de recherche utilisé nous permet de laisser le sujet libre de s’exprimer. Aucun thème n’a été proposé aux enfants. « En recueillant paroles et textes libres, le chercheur accède à tout l’univers du sujet, riche de sa singularité individuelle et de son appartenance culturelle et sociale. » (Moscarola, 2001). Ce n’est pas le développement du langage qui est étudié mais bien le discours qui, selon nous, permet un accès au sens, aux structures psychiques de l’individu. L’analyse du discours nous permet d’étudier le développement de la conscience de soi grâce à une méthodologie simple et non contraignante pour les enfants. Cette recherche trouve son originalité dans le croisement des résultats de l’analyse statistique textuelle (Lexico3, Tropes) avec les théories du développement de la conscience de soi. Les résultats de ces analyses nous montrent que dès l’instant où le je apparaît, le moi auparavant utilisé seul en tant que sujet se transforme en complément du sujet-je. En tant que complément du sujet, il objective le sujet parlant, lui permettant une mise à distance. Le sujet peut donc se regarder agir, faire où être en tant qu’objet. La forme moi-je, également fréquente dans le discours de l’enfant, est pour nous, sans doute, la forme réflexive la plus claire de l’avènement de la conscience de soi se manifestant par le biais du discours narratif autobiographique. Plus tard dans le discours de l’enfant, le je va pouvoir exister seul. Notre hypothèse est qu’étant davantage conscient de lui-même, l’enfant n’aurait plus systématiquement recours à la projection de son moi pour prendre conscience de son existence en tant qu’être parmi les autres.

In 13 neonates undergoing cardiac operations for congenital cardiac defects, complement, leukocytes, and leukocyte elastase were studied during and after cardiopulmonary bypass. All but two neonates received prostaglandin E1 before the operation. The C3d/C3 ratio rose significantly during cardiopulmonary bypass from 0.86 +/- 0.55 to 1.40 +/- 0.56 (mean +/- standard deviation; p < 0.0001). Abnormally elevated C5a levels (18.6 +/- 7.3 micrograms/L) were measured at the end of cardiopulmonary bypass. C4 was not overtly consumed during the procedure. Leukocytes fell from a preoperative value of 10.06 +/- 3.15 x 10(9)/L to 3.21 +/- 0.64 x 10(9)/L after beginning of cardiopulmonary bypass (p < 0.0001) and rose at the end of the procedure from 2.33 +/- 0.67 x 10(9)/L to 7.19 +/- 1.84 x 10(9)/L, after protamine administration (p < 0.0001). Neutrophils fell from a preoperative value of 5.14 +/- 1.18 x 10(9)/L to 1.46 +/- 0.35 x 10(9)/L after beginning of cardiopulmonary bypass and rose at the end of extracorporeal circulation from 1.00 +/- 0.31 x 10(9)/L to 4.10 +/- 1.18 x 10(9)/L, after protamine administration (p < 0.005). Elastase release occurred in all neonates during cardiopulmonary bypass and averaged 331.5 +/- 175.7 micrograms/L. Complement activation and leukocyte stimulation did not correlate with postoperative complications or outcome. This study demonstrates complement activation and leukocyte stimulation in neonates undergoing cardiac operation. [less ▲]

This paper presents recent investigations in the field of lubricant escapes from asperities. This phenomenon, named Micro Plasto Hydrodynamic Lubrication (MPHL), induces friction variation during metal forming processes. A better understanding of MPH lubrication would lead to a better management of friction, which is a central element in most sheet metal forming processes. To fulfil that goal, experiments were conducted in plane strip drawing using a transparent upper tool in order to observe lubricant flow around macroscopic pyramidal cavities. These experiments were then numerically reproduced with two complementary Finite Element models. The numerical results are discussed in this paper and show good agreement with experimental measurements. [less ▲]

This paper presents different methods to assess the odour emission and the odour annoyance in the surroundings. It is shown, on the example of landfill areas and composting facilities, that chemical analyses are helpful to identify key compounds of the odour release, and to set up the specification of a monitoring instrument. Sensitive methods, like dynamic olfactometry or sniffing team investigation, are mainly applicable to provide a global odour plume or an average annoyance zone. And the electronic nose can supply a warning signal to the plant manager or a real time estimation of the annoyance zone. [less ▲]

Plasma membranes are complex entities common to all living cells. The basic principle of their organization appears very simple, but they are actually of high complexity and represent very dynamic structures. The interactions between bioactive molecules and lipids are important for numerous processes, from drug bioavailablility to viral fusion. The cell membrane is a carefully balanced environment and any change inflicted upon its structure by a bioactive molecule must be considered in conjunction with the overall effect that this may have on the function and integrity of the membrane. Conceptually, understanding the molecular mechanisms by which bioactive molecules interact with cell membranes is of fundamental importance. Lipid specificity is a key factor for the detailed understanding of the penetration and/or activity of lipid-interacting molecules and of mechanisms of some diseases. Further investigation in that way should improve drug discovery and development of membrane-active molecules in many domains such as health, plant protection or microbiology. In this review, we will present complementary biophysical approaches that can give information about lipid specificity at a molecular point of view. Examples of application will be given for different molecule types, from biomolecules to pharmacological drugs. A special emphasis is given to cyclic lipopeptides since they are interesting molecules in the scope of this review by combining a peptidic moiety and a lipidic tail and by exerting their activity via specific interactions with the plasma membrane.

This position paper on complementary feeding summarizes evidence for health effects of complementary foods. It focuses on healthy infants in Europe. After reviewing current knowledge and practices, we have formulated these conclusions: Exclusive or full breast-feeding for about 6 months is a desirable goal. Complementary feeding (ie, solid foods and liquids other than breast milk or infant formula and follow-on formula) should not be introduced before 17 weeks and not later than 26 weeks. There is no convincing scientific evidence that avoidance or delayed introduction of potentially allergenic foods, such as fish and eggs, reduces allergies, either in infants considered at increased brisk for the development of allergy or in those not considered to be at increased risk. During the complementary feeding period, > 90% of the iron requirements of a breast-fed infant must be met by complementary foods, which should provide sufficient bioavailable iron. Cow's milk is a poor source of iron and should not be used as the main drink before 12 months, although small volumes may be added to complementary foods. It is prudent to avoid both early (< 4 months) and late ( >= 7 months) introduction of gluten, and to introduce gluten gradually while the infant is still breast-fed, inasmuch as this may reduce the risk of celiac disease, type 1 diabetes mellitus, and wheat allergy. Infants and young children receiving a vegetarian diet should receive a sufficient amount (similar to 500 mL) of breast milk or formula and dairy products. Infants and young children should not be fed a vegan diet. [less ▲]

Two complementary 3D finite element formulations, with either the magnetic field or the magnetic vector potential as unknowns, are developed to deal with the modeling of eddy currents in electrical steel laminations. The magnetic flux through the flux gates of the conducting region is imposed via the boundary terms of the weak formulations, in a natural way thanks to the use of edge finite elements. The two formulations are applied to a simple 1D eddy current problem with analytical solution. As a practical 3D application example, a T-joint region of an electrical steel lamination is considered.

The value of a predischarge exercise test combined with thallium-201 myocardial scintigraphy in detecting patients with severe multivessel disease (MVD) was studied in 58 consecutive patients discharged after a first acute myocardial infarction. Twelve electrocardiographic, clinical and scintigraphic variables were analysed. Angiography at one month revealed MVD (greater than 70% narrowing in vessels unrelated to infarction) in 26 patients (45%). ST segment depression of 1mm or greater, thallium defects in multiple vascular distributions (MVTL), and reversible thallium defects in a vascular distribution different from the infarct related vessel predicted patients at risk for MVD (predictive value respectively of 68%, 65% and 75%). The other variables were not significantly associated with the presence of MVD. Only ST segment depression and thallium defects in multiple vascular distributions emerged as independent predictors of MVD. Their combination yielded a 77% sensitivity and a 59% specificity for MVD. Combination of thallium imaging with the predischarge exercise ECG significantly improved the stratification provided by the exercise test alone (P less than 0.05). A positive thallium scan (MVTl defects) associated with a positive ECG (ST depression) carried a risk for MVD of 80% in the population studied. When both tests were negative, MVD was infrequent (risk 22%). Because improvement in the stratification of patients is not as clear as expected from studies performed at a later stage, it appears that exercise thallium scintigraphy at a submaximal level one or two weeks after infarction does not provide optimal information. Predischarge exercise thallium-201 scintigraphy, however, is superior to an exercise tolerance test alone in separating patients into those with high and low risk of MVD. [less ▲]

The RNA genome of the human T-cell leukemia virus type 1 (HTLV-1) codes for proteins involved in infectivity, replication, and transformation. We report in this study the characterization of a novel viral protein encoded by the complementary strand of the HTLV-1 RNA genome. This protein, designated HBZ (for HTLV-1 bZIP factor), contains a N-terminal transcriptional activation domain and a leucine zipper motif in its C terminus. We show here that HBZ is able to interact with the bZIP transcription factor CREB-2 (also called ATF-4), known to activate the HTLV-1 transcription by recruiting the viral trans-activator Tax on the Tax-responsive elements (TxREs). However, we demonstrate that the HBZ/CREB-2 heterodimers are no more able to bind to the TxRE and cyclic AMP response element sites. Taking these findings together, the functional inactivation of CREB-2 by HBZ is suggested to contribute to regulation of the HTLV-1 transcription. Moreover, the characterization of a minus-strand gene protein encoded by HTLV-1 has never been reported until now. [less ▲]

This paper deals with the magnetic vector and scalar potential formulation for two-dimensional (2D)finite element (FE) calculations including a vector hysteresis model, namely a vectorized Jiles-Atherton model. The particular case of a current-free FE model with imposed fluxes and magnetomotive forces is studied. The non-linear equations are solved by means of the Newton-Raphson method, which leads to the use of the differential reluctivity and permeability tensor. The proposed method is applied to a simple 2D model exhibiting rotational flux, viz the T-joint of a three-phase transformer. [less ▲]
