Biotechnology of Silk

Biotechnology of Silk

This book is a snapshot of the current state of the art of research and development on the properties and characteristics of silk and their use in medicine and industry. The field encompasses backyard silk production from ancient time to industrial methods in the modern era and includes an example of efforts to maintain silk production on Madagascar. Once revered as worth its weight in gold, silk has captured the imagination from its mythical origins onwards. The latest methods in molecular biology have opened new descriptions of the underlying properties of silk. Advances in technological innovation have created silk production by microbes as the latest breakthrough in the saga of silk research and development. The application of silk to biomaterials is now very active on the basis of excellent properties of silks including recombinant silks for biomaterials and the accumulated structural information.

Glaucoma Surgery

Glaucoma Surgery

Renowned experts present the latest knowledge in … In this volume of Developments in Ophthalmology, a panel of renowned glaucoma surgeons reports its findings and the updated evidence-based literature data on indications, outcomes, pearls and pitfalls of techniques in which they all have an undisputable ‘hands-on’ everyday experience. The publication begins with chapters on conventional procedures, i.e. trabeculectomy (still the gold standard), deep sclerectomy, and glaucoma drainage device implantation explicitly focusing on postoperative management. The role of the ocular surface in glaucoma surgery and the issue of wound healing and its modulation through antimetabolites are further discussed. In the second part, the attention shifts to new techniques which still have a marginal role, but are promising for particular indications. In the last part, the greatest challenges of glaucoma surgery such as the surgical approach to angle closure, concomitant glaucoma and cataract as well as pediatric glaucoma are discussed in detail. Finally, the last chapter is dedicated to cyclodestructive techniques. This volume is recommended to glaucoma surgeons and glaucoma specialists seeking information on the best therapy for their patients, but also to general ophthalmologists who refer their patients for surgery or follow them up afterwards.
