This prospective cohort study aimed at identifying player-related risk factors for injuries in youth football as determined by extensive preseasonal screening. All male U15-U19 players from a regional football school (season 2007-2008; n = 67) underwent preseason evaluations assessing physical fatigue, emotional stress and injury history (questionnaire), anthropometric variables, general joint laxity (Beighton score), lower limb coordination (functional hop tests), aerobic fitness (shuttle run test), strength of knee extensor and flexor muscles (isokinetic tests), static and dynamic balance (force plate tests), and explosive strength (jump tests on force plate). Football exposure and all football-related injuries (n = 163) were recorded during the entire subsequent season (44 weeks). Total injury incidence was 10.4 injuries/1000  h and was higher in competition than in training [relative risk = 3.3; CI(95%) (2.39; 4.54); P < 0.001]. Lower limb injuries were most frequent (87%). Acute contact injuries represented 37%, while intrinsic (noncontact and chronic) injuries amounted to 63%. Of all the variables tested, only physical fatigue was significantly associated with injury, as revealed by univariate and multivariate analyses. The same result was observed when considering only intrinsic injuries as outcome. A single preseason test session may be of limited interest in the framework of an injury prevention strategy.

Introduction: The study of normal structures of the sheep’s brain is very important to understand pathological changes caused by the bluetongue virus in the fetus’s brain at various stages of the gestation. Bluetongue is an arthropod-borne viral disease of domestic and wild ruminants. The serotype 8 is responsible for outbreaks in Northern Europe in 2006. This virus causes lesions in the brain of fetuses as hydrancephaly and porencephaly. The aim of this work is to improve knowledge of anatomy and histology of the central nervous system of the sheep. Methods: Seven heads of adult sheep and one from a fetus aged 4,5 months were used. All heads were first opened in the frontal area using bone’s saw and immerged in a formalin solution for 10 days. After a good fixation, the brains were extracted and sectioned. Transversal, frontal and sagittal sections were realized. The sections of two brains were stained with Berlin-blue and treated to be embedded in methylmetacrylate for gross morphology. The different parts of the 6 resting brains were then embedded in paraffin, cut and the histological sections were stained with haematoxylin/eosin, cresyl violet or by use of silver impregnation. Results: Gross morphological examination of the brains embedded in methylmetacrylate showed the detailed anatomy of the different parts. The staining with haematoxylin/eosin permitted to differentiate the grey matter, the different nucleus and the layers of cerebral and cerebellum cortex. The cresyl violet technique permitted to visualize the Nissl bodies and the silver impregnation revealed nerve fibers. In the fetus brain, blood vessels were very numerous in the brainstem, the cerebellum and the cerebrum. The grey matter was less organized and looser. Conclusion: This work establishes an anatomical and histological approach allowing future studies in ovine fetuses with and without brain lesions potentially caused by the bluetongue virus. [less ▲]

A minimal cardiovascular system (CVS) model including mitral valve dynamics has been previously validated in silico. However parameters of this model are difficult to link with structural and anatomical components of the valve. This research describes the integration of a structural model of the mitral valve in an existing closed-loop cardiovascular system (CVS) model [less ▲]

Excessive Pricing: The Flaws of ‘Tea Party Competition’ Policy

Since the adoption of the Guidance Communication in 2009, the Commission has kept exploitative abuses— and in particular excessive pricing cases—in a state of artificial hibernation, and focused on exclusionary cases as a matter of enforcement priority. The Commission’s small antitrust policy against exploitative abuses is predicated on ‘Tea Party’ competition economics: in the long term, high prices are presumed to deliver efficient outcomes, and competition enforcers risk doing more harm than good in trying to improve market outcomes [less ▲]

Le flux de dioxyde de carbone émanant du sol participe de manière prépondérante au cycle du carbone. On estime son amplitude à 68 ± 4 Pg C/an. En forêt tempérée, il représente approximativement 60-80% des émissions totales de CO2 de l’écosystème (respiration de l’écosystème). Compte tenu de l’ampleur de ce flux et des conséquences qu’aurait une quelconque modification de son amplitude sur le chargement en dioxyde de carbone de l’atmosphère, il est primordial d’améliorer la connaissance des mécanismes qui le régissent et de connaître précisément l’influence des variables du milieu (édaphiques et climatiques). Cet article vise à montrer l’intérêt d’effectuer des analyses multicouches des mécanismes à l’origine de ce flux (transport et production) plutôt que de restreindre les études à la surface du sol. De plus, cet article souligne le bénéfice apporté par l’outil isotopique pour améliorer la compréhension mécaniste de ce flux. [less ▲]
