Practical Aspects Of Hyaluronan Based Medical Products

The ballooning body of research devoted to hyaluronan (HA) reflects its enormous potential for various medical applications. There have been many successes of varying degrees in the development of medical products based on HA, but also some setbacks. While there is obviously ample information available on the chemistry and various properties of this macromolecule, Practical Aspects of Hyaluronan Based Medical Products is the first book devoted to systematically applying this knowledge to product development. Based on the author's extensive experience working with HA, this book explores in detail the chemistry, composition, formulation, testing, safety, effectiveness, quality control, and regulatory approval of HA medical products. It begins with a survey of the historical development and recent products based on hyaluronan. Subsequent chapters detail the rheological properties of the molecule and explore the chemical principles and methods forming the technical basis of product development, illustrated by more than 50 figures of chemical structures, reaction schemes, and rheological properties. Individual chapters then consider standards, tests, and analytical methods; safety of HA-based products for their indicated applications; and clinical performance, mechanism of action, and product characteristics. Practical Aspects of Hyaluronan Based Medical Products surveys FDA review documents as well as peer-reviewed journal articles to identify the elements essential to successful product development, namely, understanding the critical issues in the regulatory path and linking clinical performance of the products to their original design.

Hyaluronic acid is an essential part of connective, epithelial and neural tissues, and contributes to cell proliferation and migration. It is used as a stimulating agent for collagen synthesis and is a common ingredient in skin-care products, a multi-billion dollar industry, as it is believed to be a key factor in fighting the aging process. Hyaluronic Acid: Production, Properties, Application in Biology and Medicine consists of six chapters discussing the various issues of hyaluronic acid research. In Chapter 1, a historical analysis recounts the discovery and milestones of the research leading to the practical applications of hyaluronan. Chapter 2 is dedicated to biological role of the hyaluronic acid in nature, in particular in the human body. The chapter starts from the phylogenesis of hyaluronic acid, then describes hyaluronan functions in human ontogenesis and especially the role which hyaluronan plays in extracellular matrix of the different tissues. Chapter 3 describes the methods to manufacture and purify hyaluronic acid, including the analytical means for assessing quality of the finished product. Chapter 4 discusses the structure and rheological properties of hyaluronic acid considering effects on conformation and biological properties related to molecular weight. In Chapter 5, the physical and chemical methods for modifying the structure of hyaluronan are discussed including cross-linking using bi-functional reagents, solid-phase modification and effects of the combined action of high pressures and shift deformation. The final chapter focuses on the products derived from hyaluronic acid, including therapeutics composed of modified hyaluronan conjugated to vitamins, amino acids and oligo-peptides. The biological roles and medical applications of this polysaccharide have been extensively studied and this book provides a wealth of scientific data demonstrating the critical role of hyaluronic acid and its promise as a multifaceted bio-macromolecule. Approaching hyaluronic acid from multiple angles, this book links relationships between its biological functions, structure and physical–chemical properties. It will be an invaluable resource to researchers, both industrial and academic, involved in all aspects of hyaluronan-based technologies.

Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

The birth and exponential growth of aesthetic medicine has been phenomenal. Recent technical innovation in aesthetic devices and products, coupled with an ever-increasing awareness of physical appearance and a rise in disposable income has boosted the demand for this field of medicine beyond all expectations. Its market size is presently valued at USD 60 billion and is anticipated to continue to expand at a CAGR of 10%. Now comes a book, written by one of the pioneers of this field of medicine who started one of the first aesthetic clinics in the world from his apartment in Dublin in 1999. Since then, he has built clinics around the world and won multiple international awards for his own innovations and advanced techniques, including ‘Top Aesthetic Physician in the World’ in 2019.
