Sommario/riassunto |

Phytochemicals from natural products are now widely used as food additives (antioxidants, pigments), food supplements, cosmetic ingredients, etc. Currently, the majority of the extraction processes implemented on an industrial scale for the production of bioactive-enriched extracts are based on solvents of petroleum origin. However, contemporary trends in green extraction techniques dictate a minimization of solvent use, low-energy processes and novel eco-friendly materials that are environmentally benign. The search for liquids and/or extraction technologies that could meet such requirements is, therefore, an intriguing concept. This book addresses the concept of recovering natural bioactive substances from plant resources, using state-of-the-art extraction technologies, with prospects in the food, cosmetic and pharmaceutical industries. |

Sommario/riassunto |
|
This book is a practical guide for anyone who performs eyelid surgery, whatever their specialty, and is particularly relevant for ophthalmologists in training and non-oculoplastic surgeons who may venture into this field. The step-wise text is supported by numerous original illustrations. It emphasises a logical, minimalist approach to lid surgery and challenges some popular practices. The novel techniques unique to this volume may be of interest to experienced oculoplastic surgeons. They include emphasis on the superiority of Meibomian orifice line lid traction suture placement over using the grey line. This makes bolsterless suture tarsorrhaphy a viable and better alternative to temporary surgical tarsorrhaphy. Maximal use of direct closure and directed laissez-faire encourages tissue expansion in eyelid reconstruction, aided greatly by the placement of a magic suture. The seductively simple medial canthal thermoplasty corrects medial lid laxitywithout dissection. The control of active thyroid eye disease with orbital depot steroid injections, the importance of full orbital volume replacement after eye removal and the superiority of modified Bick lid |
