Abstract

Le hérisson d’Europe (Erinaceus europaeus ) est un petit mammifère sauvage commun, présent partout en Belgique. Aussi bien présent en campagne que dans les milieux plus urbains, il est très apprécié de la population. Parmi les agents pathogènes zoonotiques dont il peut être porteur, une bactérie a récemment été mise en évidence : Corynebacterium ulcerans. Certaines souches de C. ulcerans produisent la toxine diphtérique, responsable de lésions respiratoires et/ou cutanées de type diphtérique. Cette étude s’est concentrée sur 74 hérissons morts dans des Centres de Revalidation des Espèces Animales Vivants à l'Etat Sauvage en Région Wallonne. Ces animaux ont été autopsiés par le Service Faune sauvage (FMV, ULiège) et plusieurs analyses de laboratoires ont été effectuées (cultures bactériennes, qPCR, spectrométrie de masse MALDI-TOF, ELEK test). C. ulcerans a pu être isolé par qPCR sur 47 des 74 hérissons analysés. Parmi les cadavres positifs, on observe une majorité de hérissons présentant des lésions cutanées en accord avec les descriptions de Martel et collaborateurs (2020) et Berger et collaborateurs (2019). Cependant, il n’y a pas de différence observée selon le sexe ou l’âge, contrairement aux observations faites par ces mêmes auteurs. Des analyses sont toujours en cours et visent à déterminer si une infection systémique existe. Les premiers résultats indiquent une tendance allant vers une localisation majoritairement cutanée avec cependant des détections au niveau des organes internes indiquant une possible dissémination de C. ulcerans. En ce qui concerne la santé publique, les résultats de cette étude montrent que C. ulcerans est fréquemment isolé chez le hérisson. Le potentiel zoonotique de cette bactérie doit inciter les centres de revalidation à renforcer les bonnes pratiques d’hygiène lors de la manipulation des hérissons qui y sont soignés.

Abstract

The Hedgehog signaling pathway is an evolutionarily conserved pathway that governs complex developmental processes, including stem cell maintenance, proliferation, differentiation, and patterning. Several recent studies have shown that the aberrant activation of Hedgehog signaling is associated with neoplastic transformation, cancer cell proliferation, metastasis, multiple cancers’ drug resistance, and survival rates. This book focuses on several aspects of Hedgehog signaling in organogenesis and the tumor microenvironment, and presents reviews and original papers on recent efforts in the field of Hedgehog signaling.

Abstract

The book is devoted to the design, application and characterization of thin films and structures, with special emphasis on optical applications. It comprises ten papers—five featured and five regular—authored by scientists all over the world. Diverse materials are studied and their possible applications are demonstrated and discussed—transparent conductive coatings and structures from ZnO doped with Al and Ga and Ti-doped SnO2, polymers and nanosized zeolite thin films for optical sensing, TiO2 with linear and nonlinear optical properties, organic diamagnetic materials, broadband optical coatings, CrWN glass molding coatings, and silicon on insulator waveguides.

Abstract

Despite significant progress in our understanding of cancer biology, cancer continues to be the second cause of human mortality. The remarkable responses of cancer patients to inhibitors to the hedgehog signaling pathway implies a promising novel approach to treat cancer. As a result, understanding the role of hedgehog signaling in cancer is critically important for novel cancer therapeutics. The hedgehog pathway, initially discovered by two Nobel laureates Drs. E. Wieschaus and C. Nusslein-Volhard in Drosophila, is a major pathway regulating cell differentiation, tissue polarity, stem cell maintenance and cell proliferation. It is known by now that activation of this pathway occurs in a variety of human cancer, including basal cell carcinomas (BCCs), medulloblastomas, leukemia, gastrointestinal, lung, ovarian, breast and prostate cancers. Even more exciting is the discovery and synthesis of specific signaling antagonists for the hedgehog pathway, which have significant clinical implications in novel cancer therapeutics. To provide the most up-to-date information on recent development in this exciting research area, we have invited experts in hedgehog signaling field to summarize major advances made in the last few years on hedgehog signaling mechanisms, activation of the pathway in various human cancer types, potential antagonists for hedgehog signaling inhibition and their clinical implications for human cancer treatment. Authors of the book have also highlighted current challenges in our efforts to translate the basic biology into clinic. This book provides insightful views suitable for graduate students, medical students, undergraduate students, basic and clinical scientists, cancer patients as well as the general public.
