Nanoethics and Nanotoxicology - Philippe Houdy, Marcel Lahmani, Francelyne Marano

Nanoethics and Nanotoxicology

by: Philippe Houdy, Marcel Lahmani, Francelyne Marano

Nanobiotechnology is a fast developing field of research and application in many domains such as in medicine, pharmacy, cosmetics and agro-industry. The book addresses the lastest fundamental results on nanotoxicology and nanoethics, and the enormous range of potential applications in the fields of medical diagnostics, nanomedicine, and food and water administration.Nanoscale objects have properties leading to specific kinds of behaviour, sometimes exacerbating their chemical reactivity, physical behaviour, or potential to penetrate deeply within living organisms. Hence it is important to ensure the responsible and safe development of nanomaterials and nanotechnologies.This fourth volume in the Nanoscience series should make its mark, by presenting the state of the art in the fields of nanotoxicology and nanoethics.This is the first book to combine both scientific knowledge and ethical and social recommendations. It also presents specific policies on nanotechnologies set up by national and international authorities. This book is of interest to engineers, researchers, and graduate students.

Polysaccharides in Medicinal and Pharmaceutical Applications - Valentin Popa

Polysaccharides in Medicinal and Pharmaceutical Applications
by: Valentin Popa

This book presents new and specific aspects in the field of polysaccharides and their derivatives recommended for use in medicine and pharmacy. At the same time the aspects developed in this book will be useful to designing new systems for drugs delivery, immunomodulation, and new materials based on polysaccharides isolated from different sources and their derivatives.The structure and properties of polysaccharides from different sources with potential applications in the fields of medicine and pharmacy are discussed. Thus, the structural aspects concerning hyaluronic acids, fungal extra cellular polysaccharides, celluloses, alginates, hemicelluloses, dextran, glyconjugates and cyclodextrins are covered. The applications are described both for nonmodified and modified forms of polysaccharides for drug delivery, immunomodulation, tissue engineering and hydrogel preparation.

Controlled Release in Oral Drug Delivery - Clive G. Wilson, Patrick J. Crowley

Controlled Release in Oral Drug Delivery
by: Clive G. Wilson, Patrick J. Crowley

Controlled Release in Oral Drug Deliveryprovides focus on specific topics, complementing other books in the initial CRS series. Each chaptersets the context for the inventions described and describe the latitude that the inventions allow. In order to provide some similar look to each chapter, the coverage includes the historical overview, candidate drugs, factors influencing design and development, formulation and manufacturing and delivery system design. This volumewas written along three main sections: the relevant anatomy and physiology, a discussion on candidates for oral drug delivery and the major three groups of controlled release systems: diffusion control (swelling and inert matrices); environmental control (pH sensitive coatings, time control, enzymatic control, pressure control) and finally lipidic systems.

Common terms and phrases:

bioavailability Control Release dosage form drug delivery enteric coating excipients hydrophilic hydroxypropyl methylcellulose hypromellose ibuprofen lipid matrix polymer small intestine
