Available in PDF, EPUB and Kindle. Book excerpt: Les méthodes de stérilisation médicales demeurent inchangées depuis 40 ans. La stérilisation par chaleur humide est aujourd'hui considérée comme la technique de référence. Si elles ont prouvé leur efficacité, ces techniques ne sont cependant pas dénuées d'inconvénients : telles que la toxicité pour l'opérateur et le patient, la durée des cycles et la dégradation des instruments chirurgicaux thermosensibles comme les endoscopes. Ce travail présente tout d'abord les caractéristiques physico-chimiques d'une nouvelle technique de stérilisation utilisant les plasmas froids : un gaz inerte-peroxyde d'hydrogène par exemple-est activé par un champ électromagnétique entraînant la formation de radicaux libres et de photons ultraviolets. La deuxième partie de ce travail présente les propriétés de la stérilisation plasma comparées à celles des techniques usuelles, tant en termes d'efficacité, que de toxicité, et d'innocuité. Enfin, une dernière partie fait état des premiers résultats expérimentaux obtenus dans des conditions de milieu hospitalier, avec les premiers procédés industriels utilisant la technologie des plasmas froids.

Available in PDF, EPUB and Kindle. Book excerpt: Ce projet porte sur le développement d'applications industrielles dans le domaine des traitements de surface par plasmas froids. L'emploi de cette technologie pour le traitement de surface polymère reste de manière générale une alternative intéressante à la voie chimique. Véritable outil de recherche dédié à l'industrie, la plate-forme plasma froid du CRITT est susceptible de répondre dans ce domaine aux attentes très diverses des industriels. Un des thèmes émergents de ces dernières années concerne l'utilisation de ces plasmas comme moyen alternatif pour la stérilisation des dispositifs médicaux. En effet, les techniques conventionnelles ne permettent pas une inactivation performante de certains micro-organismes pathogènes et les conditions de traitement parfois extrêmes n'assurent pas la pérennité du matériel médical. Préalablement à une validation clinique nécessaire à son développement en milieu industriel ou médical, ce nouveau procédé doit naturellement faire la preuve de son efficacité. L'étude réalisée présente les principaux mécanismes susceptibles d'expliquer l'inactivation d’un micro-organisme exposé au plasma. L'action en synergie de photons UV et d'espèces actives comme l'oxygène atomique confère à cette technologie une cinétique d'inactivation particulière. La production de ces agents actifs est optimisée par un diagnostic du plasma en spectroscopie optique, permettant ainsi d';atteindre des degrés d'inactivation très prometteurs. Même si l'efficacité du plasma n'est plus à démontrer, la problématique du conditionnement, qui fait partie intégrante d'un procédé, se pose toujours en milieu industriel. L'inhibition du plasma diffusant à travers un sachet poreux ne permet pas d'obtenir l'état stérile. Une solution consistant à générer un plasma induit dans un sachet, assurant ainsi un contact intime entre les espèces actives du plasma et le dispositif à stériliser, est donc discutée.

Available in PDF, EPUB and Kindle. Book excerpt: With the increased importance of hospital administration and continuous emergence of new infectious pathogens, particular attention should be paid to avoid iatrogenic diseases by minimising the contamination of medical instruments with infectious pathogens and toxins. It is well known that one of the most effective ways to prevent hospital-acquired infection is to implement a sterilisation and disinfection system that includes physical and chemical inactivation methods. This book presents information on the current status and future perspectives of a state-of-art physical technique, gas plasma sterilisation.

Available in PDF, EPUB and Kindle. Book excerpt: In vitro Embryogenesis in Plants is the first book devoted exclusively to this topic. As the ultimate demonstration of totipotency in plants, somatic and haploid embryogenesis is of vital importance to all those working on or interested in basic and applied aspects of plantlet information and regeneration. The text includes comprehensive reviews written by experts, on all facts of in vitro and in vivo embryogenesis. Some chapters deal with the morphogenic, structural and developmental, physiological and biochemical, and molecular biological aspects of the subject. Chapters are also devoted to haploid embryogenesis, asexual embryogenesis in nature, zygotic embryogenesis, and zygotic embryo culture. Detailed tables summarizing successful somatic embryogenesis in all vascular plants are also included. This book, therefore, brings together previously scattered information to provide an indispensable reference book for both active researchers, graduate students and anyone interested in this aspect of tissue culture technology and plant development.

Book excerpt: Cold atmospheric plasma (CAP) is a promising and rapidly emerging technology for a wide range of applications, from daily life to industry. CAP’s key advantage is its unique ability to effectively deliver reactive species to subjects including biological materials, liquid media, aerosols, and manufactured surfaces. This book assesses the state-of-art in CAP research and implementation for applications including agriculture, medicine, environment, materials, catalysis, and energy. The mechanisms of generation and transport of the key reactive species in the plasma are introduced and examined in the context of their applications. Opportunities and challenges for novel technologies, fresh ideas/concepts, expanded multidisciplinary study, and new applications are discussed. The authors’ vision for the converging trends across diverse disciplines is proposed to stimulate critical discussions, research directions, and collaborations.

This book was released on 2011-12-20 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-line HDF represents a major technical development in the delivery of hemodialysis therapy: It combines the properties of increased diffusion available in current high-flux membranes with convective removal of between 6 and 30 liters per treatment and requires the use of ultrapure water and online filtration of replacement fluid. On-line HDF has been successfully introduced in Europe and Asia and is routinely prescribed for dialysis patients in these regions.The book at hand summarizes the history and achievements of on-line HDF in four parts: A report of the technological development in both machine and fiber/dialyzer is followed by a description of the challenges encountered in the evolution of on-line HDF, collecting the accounts of clinical key opinion leaders who had been involved in its early application. The third part presents a comprehensive review of the clinical results achieved with on-line HDF from its inception to the present times, in which it represents the clinical golden standard. The fourth and final part is dedicated to on-line HDF as a ‘vision’ for the future.
