L’écornage des veaux est une pratique courante en élevage bovin. En Europe, 81% des veaux laitiers, 47% des animaux à l’engrais et 68% des veaux allaitant sont écornés (d’après Cozzy, 2015). Il permet, entre autre, d’accroître la sécurité de l’éleveur et des animaux. L’écornage est faiblement réglementé, mais des préconisations mentionnent des protocoles aux fins de limiter la souffrance du veau autant que possible. Parmi les protocoles utilisés, l’écornage thermique est le plus pratiqué sur le terrain. Réalisé durant les 2 premiers mois de vie de l’animal, il se fait idéalement sous sédation, avec une anesthésie locale et un anti-inflammatoire. Le vétérinaire applique l’écorneur sur le bourgeon cornual à une température de 500 à 700° et durant un temps de l’ordre de 7 à 10 secondes. Ce protocole pose la question de l’impact d’une telle augmentation de température sur les structures situées à proximité. On peut se demander quelles sont les lésions possibles causées lors de l’écornage du fait du couple temps-température. Notre hypothèse est qu’il y a une augmentation de température au niveau du cerveau. Afin d’estimer cette température, nous avons placé un thermomètre intracrânien, situé sous le bourgeon cornual, pour mesurer la température lors d’un écornage thermique sur des veaux en post-mortem. Bien que présentant certaines limites, le protocole ne permet pas de montrer une augmentation significative de température pour une durée courte (10 secondes) d’écornage. En revanche, sur un temps plus long, il est observé une augmentation de température intracrânienne de plusieurs degrés. Ainsi, le respect du temps préconisé d’écornage de moins de 10 secondes permet d’éviter une augmentation importante de température intracrânienne.

Introduction : Selon l’Organisation Mondiale de la Santé (OMS), environ 3,2 millions de décès au niveau mondial chaque année sont attribuables au manque d’exercice. Une revue de la littérature montre l'importance de l'activité sportive pour la santé. Celle-ci prend une dimension supplémentaire chez les personnes atteintes de lésion de la moelle épinière (LME). Selon la littérature le sport fait partie du traitement lors de la rééducation afin de familiariser les personnes handicapées physiques avec le sport, améliorer leur forme physique et leur qualité de vie, les encourager à mener une vie physiquement active après leur sortie de l'hôpital. Objectif : Il s’agissait de déterminer les freins de la poursuite d’activité sportive en post revalidation chez les personnes handicapées suite à une atteinte médullaire, ayant bénéficié de sport durant leur hospitalisation au centre de revalidation neurolocomotrice du CHUOA. Matériels et méthode : 34 participants ont complété un questionnaire auto-administré. Il s’agissait des personnes âgées d’au moins 18 ans, avec une bonne connaissance du français, ayant séjourné au CHUOA dans le cadre d’une première hospitalisation en revalidation dans un contexte de handicap moteur lié à une LME, ayant bénéficié de sport durant leur hospitalisation. Les analyses statistiques se sont faites via le logiciel de traitement statistique R version 3.4.2. L’analyse multivariée par régression logistique binaire a déterminé l’impact des différentes variables significatives en analyses univariées (p-valeur < 0.05) sur la probabilité de ne pas faire du sport en post revalidation. Résultats : Le niveau d’atteinte médullaire et le fait pour les personnes handicapées moteur de penser que le sport est essentiel ou important étaient significativement associés à la probabilité de ne pas faire du sport en post revalidation (p-valeur< 0.05). Cette probabilité était augmentée de 14.6 fois et 25.3 fois respectivement (p-valeur < 0.05), lorsque le sujet avait une atteinte au niveau de la moelle cervicale et lorsque pour lui faire du sport pour une personne à mobilité réduite (PMR) n’était pas essentiel. Conclusion : Le niveau d’atteinte médullaire et l’importance que revêt l’activité sportive pour les personnes en situation de handicap apparaissent comme des éléments essentiels dans la poursuite ou non de l’activité sportive en post revalidation. Mots clés : lésion de la moelle épinière ; paraplégie ; tétraplégie ; revalidation ; sport. Abstract Introduction : According to the World Health Organization (WHO), about 3.2 million deaths worldwide each year are attributable to lack of exercise. A review of the literature shows the importance of sports activity for health. This takes an extra dimension in people with spinal cord injury (SCI). according to the literature, sport is part of the treatment during rehabilitation in order to familiarize people with physical disabilities with sport, improve their fitness and quality of life, encourage them to lead a physically active life after discharge from the hospital. Aim: The aim was to determine the brakes of post-revalidation sports activity following disability in the spinal cord, having benefited from sports during their hospitalization at the CHUOA neurolocomotor revalidation center. Materials and methods: 34 participants completed a self-administered questionnaire. These were people aged at least 18 years old, with a good knowledge of French, having stayed at the CHUOA as part of a first hospitalization in revalidation in a context of motor disability related to a SCI, who benefited from sport during their hospitalization. Statistical analyzes were performed using the R statistical package version 3.4.2. The impact of variables, statistically significant in uni-variate analyzes (p-value <0.05), on the probability of exercising in post-revalidation, were assessed using a multi variate binary logistic regression. Results: The level of SCI and the fact that people with motor disabilities think that sport is essential or important were significantly associated with the probability of not participating in post-revalidation sport (p-value< 0.05). This probability was increased by 14.6 times and 25.3 times, respectively (p-value< 0.05), when the subject had an injury in the cervical cord and when to exercise for a person with reduced mobility (PRM) was not essential. Conclusion: Both level of medullary involvement and the importance of sport activity for people with disabilities appear as essentials elements in the pursuit or not post-revalidation sport activity. Key words: spinal cord injury; paraplegia; quadriplegia; revalidation; sport.

This book explains how to optimize clinical conditions for detection of the earliest visible signs of dental caries and how best to assess caries activity as a basis for effective management. The available evidence from the literature on detection criteria and methods is distilled and placed in a clinical context to facilitate implementation in clinical practice. Guidance is offered on removal of the dental biofilm and the potential impact of various factors on the performance of different caries detection devices. The histological changes that occur during the caries process and their effect on the clinical appearance of caries lesions are explained. In addition, several caries classification systems based on visual detection criteria and designed to allow staging are presented. Consideration is also given to currently marketed detection aids, including methods involving light fluorescence, transillumination, and radiography. In each case, a summary of the detection performance, based on available supporting evidence, is tabulated together with advice on appropriate clinical application. The reader will find the text to be clearly written and informative, with many supporting clinical images.

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.

Advancements in high-throughput “Omics” techniques have revolutionized plant molecular biology research. Proteomics offers one of the best options for the functional analysis of translated regions of the genome, generating a wealth of detailed information regarding the intrinsic mechanisms of plant stress responses. Various proteomic approaches are being exploited extensively for elucidating master regulator proteins which play key roles in stress perception and signaling, and these approaches largely involve gel-based and gel-free techniques, including both label-based and label-free protein quantification. Furthermore, post-translational modifications, subcellular localization, and protein–protein interactions provide deeper insight into protein molecular function. Their diverse applications contribute to the revelation of new insights into plant molecular responses to various biotic and abiotic stressors.
