A microfluidic chip based model for the study of full thickness human intestinal tissue using dual flow

© 2016 Author(s). The study of inflammatory bowel disease, including Ulcerative Colitis and Crohn's Disease, has relied largely upon the use of animal or cell culture models; neither of which can represent all aspects of the human pathophysiology. Presented herein is a dual flow microfluidic device which holds full thickness human intestinal tissue in a known orientation. The luminal and serosal sides are independently perfused ex vivo with nutrients with simultaneous waste removal for up to 72 h. The microfluidic device maintains the viability and integrity of the tissue as demonstrated through Haematoxylin & Eosin staining, immunohistochemistry and release of lactate dehydrogenase. In addition, the inflammatory state remains in the tissue after perfusion on the device as determined by measuring calprotectin levels. It is anticipated that this human model will be extremely useful for studying the biology and tes ting novel interventions in diseased tissue

Lignes directrices pour de meilleures pratiques en matière de suivi de la santé et de contrôle des maladies des populations de grands singes

Ces lignes directrices ont pour objectif de fournir aux gouvernements, aux décideurs politiques, aux acteurs de la conservation, aux chercheurs, aux professionnels du tourisme de vision des grands singes et aux bailleurs de fonds des recommandations en terme de meilleures pratiques pour le suivi sanitaire des grands singes et la prévention des maladies. Ces recommandations reprennent et mettent à jour, le cas échéant, les normes antérieures de protection sanitaire recommandées par Homsy (1999). Tout en reconnaissant que le risque zéro de maladie n’existe pas et que les mesures de prévention ou de contrôle de la propagation des maladies n’élimineront jamais le risque, ces recommandations visent principalement à minimiser, plutôt qu’à tenter d’éliminer la menace de transmission de maladies des hommes aux grands singes. L’application des meilleures pratiques présentées ici devrait réduire substantiellement les risques que les activités humaines peuvent poser à la santé des grands singes, et ce faisant, envoyer un signal clair d’engagement vis-à-vis de la conservation des grands singes

Best Practice Guidelines for Health Monitoring and Disease Control in Great Ape Populations

First paragraph: Due to their phylogenetic relatedness, great apes and humans share susceptibility to many infectious diseases, and the potential for new diseases to be transmitted to wild great apes is of particular concern (Calvignac-Spencer et al. 2012). As great ape tourism becomes more popular, great ape research more imperative, and landscape conversion more rampant, the risk that human pathogens will be introduced to immunologically naïve wild populations becomes greater, and this could result in catastrophic losses of great apes. Therefore, it is critical that tourism and research projects involving close proximity1 between great apes and people assess the risks entailed, and establish and implement disease prevention and control measures. Disease prevention should be regarded as a top priority, recognising that it is easier and more economical to prevent the introduction of an infectious agent into a great ape population, than to attempt to treat, control or eradicate a health problem once introduced. Disease prevention programmes should be centred on monitoring health parameters, and modifying human activities accordingly, in order to reduce the risk of disease transmission to great apes. By design, such programmes will also minimise the risk of disease transfer from great apes to humans, and even from humans to other humans. Continual monitoring of the health of great apes forms the basis for establishing what is normal and abnormal and thus improves our understanding of great ape population health, allows us to determine the effectiveness of disease prevention and health management strategies, and provides a basis for conducting responsible and reasonable health interventions when needed.  To access this book go to: https://portals.iucn.org/library/node/4579
