Complementary to the muscle strength measurement, the isokinetic dynamometry offers the opportunity to investigate another essential variable: the fatigue which can be defined as a deterioration in maximum torque generating capacity. Many articles in the literature refer to isokinetic fatigue protocols, yet we may consider that there is a lack of consensus about testing modalities and methodological aspects. The overall aim of that preliminary study was to investigate concentric fatigue protocols in terms of contraction number, measurement reproducibility and appropriateness of parameters classically analysed. Twelve male subjects (23  2 years old; 71  3 kg) without history of lower limb injury were included in the study. After standardized warm-up and familiarization with the isokinetic exercise (Biodex 3 dynamometer), each subject performed a unilateral concentric testing on their dominant side knee flexors and extensors. The protocol consisted in 50 maximal contractions at 180°/s angular velocity along a constant 100° range of motion. The fatigue protocol was repeated at 3 different sessions, separated by one week, in the same standardized conditions. Measured and calculated parameters were analysed: maximal work (Wmax); total work (Wtot); cumulated work on 10-20-30-40-50 repetitions (W10-20-30-40-50); different fatigue indexes: mean on the 3 last reps/Wmax (W3L/Wmax), mean on the 5 last reps/Wmax (W5L/Wmax), W3L/mean on the 3 first reps (W3L/W3F), W5L / mean on the 5 first reps (W5L/W5F). These fatigue indexes were established from the 50 repetitions protocol but also calculated on the 30 and 40 first repetitions of the whole test. The heart rate (HR) throughout the fatigue protocol was recorded using a Polar cardiofrequencemeter. A generalized linear mixed model (GLMM) was used for the statistical analysis of reproducibility. The cumulated work calculated on 20, 30, 40 or 50 repetitions was found to be reproducible for the Q muscle group. The same parameters calculated on the Fl muscle group showed a less satisfactory reproducibility. Among indexes of fatigue, the most reproducible were those using Wmax as denominator (by contrast with W3F or W5F as denominator), in particular the W5L/Wmax index for the Q. From 20 repetitions to the end of exercise, the fatigue indexes calculated on the Fl were significantly (p < 0.05) inferior to the indexes established for the Q, suggesting a more marked effect of fatigue on the Fl decrease of maximal strength production. With respect to the HR expressed in percentage of the theoretical maximal HR, the value averaged 53 % before exercise, 83 % after 20 reps and peaked at 87 % after 50 reps. After 2 minutes of recovery, the HR reached 58 % of the HR max. These findings must be taken into account when designing a fatigue isokinetic protocol, in terms of exercise duration and parameters to be analysed. [less ▲]

Cet article explore quelques-unes des implications des nouvelles orientations politiques en matière de formation, celles qui ont été annoncées dès 1995 par la Commission Européenne. Dans un Livre blanc « Enseigner et apprendre : vers la société cognitive », on pouvait lire que « l’éducation et la formation deviendront encore davantage les principaux vecteurs d’identification, d’appartenance, de promotion sociale et d’épanouissement personnel. C’est par l’éducation et la formation, acquises dans le système éducatif institutionnel, dans l’entreprise ou de façon plus informelle, que les individus maîtriseront leur avenir et assureront leur épanouissement personnel ».

Root treatment by the non-pathogenic Pseudomonas putida strain BTP1 reduced by 34% the disease caused by Botrytis cinerea on tomato leaves. This induced systemic resistance phenomenon is associated both with the accumulation of fungitoxic material and with the stimulation of the lipoxygenase pathway in infected leaves. More precisely, we observed a consistent change in the expression of a new tomloxF gene in the leaves from BTP1-treated plants as far as the pathogen is introduced. This suggests that the roots were primed and reacted locally to colonization by bacteria and that defense-related gene expression is turned on systemically upon pathogen perception [less ▲]

La victoire de l'économie de marché sur l’économie administrée ne s’est pas traduite par un abandon pur et simple des activités économiques au capitalisme sauvage. La puissance publique s’est en effet efforcé de réinvestir le champ économique sous une nouvelle forme : la régulation. Ce nouveau mode de relation entre le marché et l’État implique, le plus souvent, la mise en place d’autorités administratives indépendantes, chargées de contrôler le respect de l’équilibre entre les différents intérêts en présence (entreprises, consommateurs, fournisseurs, administrations, etc.) sur les marchés concernés. Tel est le cas, en particulier, dans les secteurs des sociétés cotées, des marchés financiers, des télécommunications, des services postaux et de l’énergie. Pour son 56e séminaire - dont le présent ouvrage reprend les actes -, la CDVA a décidé de consacrer une réflexion approfondie à cette mutation profonde du droit et de l’économie, en faisant appel à des spécialistes réputés de la matière et à des praticiens immergés dans la discipline, tous soucieux d'éclairer les enjeux de ce nouvel ordre juridique régulatoire.

The first aim of this study was to establish a profile of age-related normal serum concentrations of osteocalcin (OC) in Ardenner horses. For this first part, blood samples from 49 healthy Ardenner horses were collected. The second aim was to study two biochemical markers of bone metabolism, OC and a carboxy-terminal cross-linking telopeptide of type I collagen (CTX-I), in 30 young Ardenner horses during 1 year. Amongst them, 17 showed lesions of juvenile degenerative joint disease in the distal forelimbs. A specific radioimmunoassay for equine OC was used to measure the serum concentration of the marker. The serum concentration of CTX-I was measured using a commercially available human assay validated for use in the horse. The effect of age, sex, season and health status (with or without lesions) was assessed. Levels of OC fall between birth and the adult stage: this decrease being most marked between birth and 1 year of age. This age-related decrease of OC was confirmed in the 30 young Ardenner horses, but CTX-I levels remained constant in this group. The Levels of the two markers changed significantly with the season with higher concentrations during the winter. No significant difference was shown either between the two sexes or between the two health statuses. [less ▲]

Human beings are communication beings. When a child is deprived of sound social relationships he suffers of serious development impairments. In humans, communication is firstly multi-canal and permanent. Language comes second. This is why animals may have true relationships with humans, although they are not language creatures. Human/animal interactions and communication rely first on touch and gaze, and this tunes the relationship at once in the intimate mode. The mere presence of an animal might also facilitate social communication. Most importantly, the human/animal relationship has some characteristics that give a real therapeutic potential to it. Because the communication is mostly nonverbal and relational, many patients are able to efficiently relate to animals although they are very deficient in their contacts with other human beings. According to the specific difficulties of the patient and to the therapist’s choices, several aspects of the human/animal interaction may be used in a therapeutic setting. [less ▲]

Olefin metathesis is a metal-catalysed organic reaction, which involves the statistical redistribution of carbon-carbon double bonds. Since its discovery in the 1950's, this transformation has gained widespread use in research laboratories and industry for making products ranging, from drugs and polymers to enhanced fuels. Its advantages include the ability to build up complex structural scaffolds with remarkable atom economy. Major industrial processes usually rely on inexpensive, ill-defined, multicomponent catalytic systems, while research laboratory applications take advantage of well-defined metal alkylidene complexes of molybdenum and ruthenium that combine high activities and ease of set-up under reproducible conditions, albeit at the price of a higher cost.
