(Quatrième de couverture): Le rôle joué par les médias de masse dans un certain nombre de phénomènes politiques et sociaux contemporains est régulièrement dénoncé et critiqué, la plupart du temps sans être appréhendé de manière précise mais en se fondant sur leurs effets supposés. Par une analyse des discours de presse qui ont entouré le « Dimanche noir » du 21 avril 2002, cet ouvrage propose de revenir sur le paradoxe apparent qui vit, lors de cette campagne présidentielle, un candidat déclaré illégitime par la presse remporter un succès électoral inattendu. L’analyse montre comment des discours massivement dénonciateurs ont eu des effets de légitimation contraires aux intentions des auteurs et au contenu même de leurs propos. Son originalité est de s’intéresser, au-delà de la machine médiatique et des composantes langagières des discours, à la relation que les journalistes proposent à leurs lecteurs. Elle se réfère également à un certain nombre de mythes qui orientent l’écriture journalistique pour mettre en lumière la contradiction entre l’engagement des journalistes dans des valeurs de « défense de la démocratie » et la caution qu’ils se donnent d’un discours objectif. Elle démonte ainsi l’ensemble d’un dispositif d’écriture contre-productif qui, s’il n’est pas seul en cause, éclaire néanmoins d’un jour nouveau le rôle des médias dans le succès électoral de Jean-Marie Le Pen, et en appelle à la responsabilité de la presse.

An equine fetlock joint pendulum test was studied and the influence of post mortem time and intra-articular lipid solvent on the viscous frictional response examined. Fresh equine digits (group 1, n=6 controls; group 2, n=6 lipid solvent) were mounted on a pendulum tribometer. Assuming that pendular joint damping could be modelled by a harmonic oscillator fluid damping (HOFD), damping time (τ), viscous damping coefficient (c) and friction coefficient (μ) were monitored for 5h under experimental conditions (400N; 20°C). In all experiments, pendular joint damping was found to follow an exponential decay function (R(2)=0.99714), which confirmed that joint damping was fluid. The evolution of τ, c and μ was found to be significantly (P<0.05) different in the two groups, with a decrease in τ and an increase in c and μ that was faster and more prominent in digits from group 2. It was concluded that pendular joint damping could be modelled by a HOFD model. The influence of post mortem time on results suggested that, ideally, joint mechanical properties should only be tested on fresh cadavers at the same post mortem time. Moreover, the addition of lipid solvent was found to be responsible for upper viscous friction parameters and for a reduced damping time, which suggested that articular lubricating ability was compromised. This equine pendulum test could be used to test the efficacy of various bio-lubricant treatments. [less ▲]

This study describes an equine fetlock joint pendulum test, and investigates the influence of post mortem time and intra-articular lipid solvent on the viscous frictional response. Fresh equine digits (control group 1 (n = 6); lipid solvent group 2 (n = 6)) were mounted in a pendulum tribometer. Assuming that pendular joint damping could be modelled by a harmonic oscillator fluid damping (HOFD), damping time (t), viscous damping coefficient (c ) and friction coefficient (µ) were then followed for 5 hours under experimental conditions (400 N; 20 °C). In all experiments, pendular joint damping was found to follow an exponential decay function (R² = 0.99714), which confirms that joint damping is fluid. The evolution of t, c and µ was found to be significantly (P <0.05) different in the two groups. Indeed, t decreased and c and µ increased more rapidly and strongly in the group 2. It was concluded that pendular joint damping can be modelled by an HOFD model. The influence of post mortem time on results suggests that, ideally, joint mechanical properties should only be tested on fresh cadavers at the same post mortem time. Finally, the addition of lipid solvent was found to be responsible for upper viscous friction parameters and for a reduced damping time, which suggests that articular lubricating ability was compromised.

En l’espace d’une décennie (2000-2010), la Chine a profondément bouleversé la carte économique latino-américaine. Voyant leurs échanges bilatéraux progresser rapidement, nombre de pays du sous-continent se sont engagés avec elle dans de nouveaux schémas de coopération et de partenariats, écornant le traditionnel leadership des États-Unis dans la région. Là où nombre d’études portent un regard croisé sur les relations sino-latino-américaines, celle-ci se propose d’étudier la stratégie de projection internationale de la Chine en Amérique latine. En appréhendant les différentes dimensions de la puissance chinoise à travers ses actions de politique extérieure (multidirectionnelle) et la diplomatie incantatoire y afférent (discours officiels), elle mesurera la capacité d’influence de la Chine à travers l’écart entre discours (promesses) et réalité (réalisations concrètes), entre l’image d’acteur mondial dont elle se prévaut (représentation) et la position qu’elle occupe véritablement sur la scène internationale (légitimité). Avec en toile de fond l’hypothèse suivante : si la Chine change la dynamique du système international actuel, en transforme-t-elle pour autant la structure ? [less ▲]

The pharmacokinetic behaviour of enrofloxacin (ENRO) in plasma and nasal secretions of healthy pigs was investigated, after a single-dose intramuscular administration of 2.5 mg/kg body weight of the drug. Blood samples and nasal secretions were collected at predetermined times after drug administration. Concentrations of ENRO and its active metabolite ciprofloxacin (CIPRO) were determined in plasma and nasal secretions by high-performance liquid chromatography (HPLC). CIPRO was not detected probably because we investigated young weaned pigs. The data collected in 12 pigs for ENRO were subjected to noncompartmental analysis. In plasma, the maximum concentration of drug (C-max), the time at which this maximum concentration of drug (T-max) was reached, the elimination half-life (t(beta)(1/2)) and the area under the concentration vs. time curve (AUC) were, respectively, 694.7 ng/mL, 1.0 h, 9.3 h and 8903.2 ng h/mL. In nasal secretions, Cmax, Tmax, t(beta)(1/2) and AUC were, respectively, 871.4 ng/mL, 2.0 h, 12.5 h and 11 198.5 ng.h/mL. In a second experiment conducted in 10 piglets, the relationship between concentrations of ENRO measured in the plasma and the nasal secretions has been determined following single-dose intramuscular administration of 2.5, 10 or 20 mg/kg body weight of the drug. It has been demonstrated that, among several variables, i.e., (1) the dose administered, (2) the time between intramuscular injection and blood sampling, (3) the age, (4) the sex, (5) the animal body weight and (6) the plasma concentration of the drug, only the latter influenced significantly the ENRO concentration in nasal secretions. Practically, using a generalized linear mixed model, ENRO concentrations in the nasal secretions (mu g/mL) can be predicted taking into account the ENRO concentrations in plasma (mu g/mL), according to the following equation: ENROnasal secretion 1.94 ENROplasma - 0.24.

Atomic force microscopy (AFM) combined with surface pressure-area isotherms were used to probe the interfacial behavior of phospholipid monolayers following penetration of surfactin, a cyclic lipopeptide produced by Bacillus subtilis strains. Prior to penetration experiments, interfacial behavior of different surfactin molecules (cyclic surfactins with three different aliphatic chain lengths-S13, S14, and S15-and a linear surfactin obtained by chemical cleavage of the cycle of the surfactin S15) has been investigated. A more hydrophobic aliphatic chain induces greater surface-active properties of the lipopeptide. The opening of the peptide ring reduces the surface activity. The effect of phospholipid acyl chain length (dimyristoylphosphatidylcholine, dipalmitoylphosphatidylcholine- (DPPC), and distearoylphosphatidylcholine) and phospholipid polar head (DPPC, dipalmitoylphosphatidylethanolamine and dipalmitoylphosphatidylserine) on monolayer penetration properties of the surfactin S15 has been explored. Results showed that while the lipid monolayer thickness and the presence of electrostatic repulsions from the interfacial film do not significantly influence surfactin insertion, these parameters strongly modulate the ability of the surfactin to alter the nanoscale organization of the lipid films. We also probed the effect of surfactin structure (influence of the aliphatic chain length and of the cyclic structure of the peptide ring) on the behavior of DPPC monolayers. AFM images and isotherms showed that surfactin penetration is promoted by longer lipopeptide chain length and a cyclic polar head. This indicates that hydrophobic interactions are of main importance for the penetration power of surfactin molecules. [less ▲]

As the protein sequence and structure databases expand, the relationships between proteins, the notion of protein superfamily, and the driving forces of evolution are better understood. Key steps of the synthesis of the bacterial cell wall peptidoglycan are revisited in light of these advances. The reactions through which the D-alanyl-D-alanine depeptide is formed, utilized, and hydrolyzed and the sites of action of the glycopeptide and beta-lactam antibiotics illustrate the concept according to which new enzyme functions evolve as a result of tinkering of existing proteins. This occurs by the acquisition of local structural changes, the fusion into multimodular polypeptides, and the association into multiprotein complexes. [less ▲]

Streptomyces R61 and S. rimosus have an atypical penicillin-binding protein (PBP) pattern characterized by a large amt. of a 25,000-mol.-wt. protein and a small amt. of a 50,000-mol.-wt. protein. The 25,000-mol.-wt. PBP exhibits high thermostability and apparently is the membrane-bound enzyme which catalyzes the model transpeptidase reaction in which Ac2-L-Lys-D-Ala-D-Ala serves as the carbonyl donor and Gly-Gly as the amino acceptor. Whether the thermolabile 50,000-mol.-wt. PBP is also a transpeptidase and is degraded into small fragments or converted into the 25,000-mol.-wt. PBP is unclear. [on SciFinder(R)] [less ▲]

A penicillin-resistant mutant, JH2-2r (MIC 75 microg ml(-1)), was isolated from Enterococcus faecalis JH2-2 (MIC 5 microg ml(-1)) by successive passages on plates containing increasing concentrations of benzylpenicillin. A comparison of the penicillin-binding protein (PBP) profiles in the two strains revealed a more intensely labelled PBP4 in JH2-2r. Because the sequences of the JH2-2 and JH2-2r pbp4 genes were strictly identical, even in their promoter regions, this intensive labelling could only be associated with an overproduction of the low-affinity PBP4. No psr gene analogous to that proposed to act as a regulator of PBP5 synthesis in Enterococcus hirae and Enterococcus faecium could be identified in the vicinity of pbp4 in E. faecalis JH2-2 and JH2-2r. However, a psr-like gene distant from pbp4 was identified. The cloning and sequencing of that psr-like gene from both E. faecalis strains indicated that they were identical. It is therefore postulated that the PBP4 overproduction in E. faecalis JH2-2r results from the modification of an as yet unidentified factor. [less ▲]
