This volume of the Keio University International Symposia for Life Sciences and Medicine contains the proceedings of the 13th symposium held under the sponsorship of the Keio University Medical Science Fund. The fund was est- lished by the generous donation of the late Dr. Mitsunada Sakaguchi. The Keio University International Symposia for Life Sciences and Medicine constitute one of the core activities sponsored by the fund,of which the objective is to contribute to the international community by developing human resources, promoting scienti?c knowledge, and encouraging mutual exchange. Each year, the Committee of the International Symposia for Life Sciences and Medicine selects the most signi?cant symposium topics from applications received from the Keio medical community. The publication of the proce- ings is intended to publicize and distribute the information arising from the lively discussions of the most exciting and current issues presented during the symposium. On behalf of the Committee, I am most grateful to the late Dr. Sakaguchi, who made the series of symposia possible. We are also grateful to the prominent speakers for their contribution to this volume. In addition, we would like to acknowledge the ef?cient organizational work performed by the members of the program committee and the staff of the fund. Naoki Aikawa, M. D. , D. M. Sc. , F. A. C. S.

Currently, hemoglobin (Hb)-based oxygen carriers (HBOCs) are leading candidates as red blood cell substitutes. In addition, HBOCs are also potential oxygen therapeutics for treatment of patients with critical ischemic conditions due to atherosclerosis, diabetes and other conditions. This book will provide readers a comprehensive review of topics involved in the HBOC development. It focusses on current products and clinical applications as well as on emerging technologies and future prospects.

Tens of thousands of different animal species live on this planet, having survived for millions of years through adaptation and evolution, which has given them a vast variety of structures and functions. Biomechanical studies of animals swimming and flying can aid understanding of the mechanisms that enable them to move effectively and efficiently in fluids . Based on such understandings and analyses, we can aim to develop environmentally friendly machines that emulate these natu ral movements. The Earth Summit in Rio de Janeiro in 1992 agreed major treaties on biological diversity, addressing the comb ined issues of environmental protection and fair and equitable economic development. With regard to coastal environments, increasing biological diversity has begun to play an important role in reestablishing stable and sustainable ecosystems. This approach has begun to influence research into the behavior of aquatic species, as an understanding of the history of an individual aquatic species is indispensable in constructing an environmental assessment mod el that includes the physical, chemical, and biological effects of that species . From an engineering viewpoint, studying nature's biological diversity is an opportunity to reconsider mechanical systems that were systematically constructed in the wake of the Industrial Revolution. We have been accumulating knowledge of the sys tems inherent in biological creatures and using that knowledge to create new, envi ronmentally friendly technologies.

Artificial Cells are not to reproduce biological cells but to prepare an artificial system for possible uses in medicine and other areas. Many of the ideas on artificial cells are being extensively applied and extended by researchers worldwide, resulting in rapid and exciting progress and discoveries. Different configurations include using emulsion methods and microfluidizers to form microscopic or nano dimension cells called artificial cells, synthetic cells, microcapsules, nanocapsules, liposomes, microparticles, nanoparticles, polymersomes, etc. Macro dimensions artificial cells are used for bioencapsulated cells. Soluble nanobiotherapeutics can be formed by crosslinking proteins and enzymes or by PEG conjugation. The principle of artificial cell has now evolved into nanomedicine, biotherapeutics, blood substitutes, drug delivery, enzyme/gene therapy, cancer therapy, cell/stem cell therapy, nanoparticles, liposomes, bioencapsulation, replicating synthetic cells, cell encapsulation, biosorbent/immunosorbent hemoperfusion/plasmapheresis, regenerative medicine, encapsulated microbe, COVID_19 vaccine, COVID_19 therapy, nanobiotechnology, nanotechnology and other areas.

The Update compiles the most recent, widespread developments of experimental and clinical research and practice in one comprehensive reference book. The chapters are written by well recognized experts in the field of intensive care and emergency medicine. It is addressed to every on involved in internal medicine, anesthesia, surgery, pediatrics, intensive care and emergency medicine.

This book aims to be a guide to the practice of blood conservation. The first chapter discusses the legal and administrative aspects of bloodless medicine describing the legal principles and practical issues relatd to refusal of transfusion. The second is on balancing the risks and benefits of transfusion includes clinical vignettes of appropriate and inappropriate transfusion. The remainder of the book covers the principles and practice of bloodless medicine, including a chapter on the scientific issues of haemostasis and the investigation of bleeding idsorders. The book concludes with chapters on blood conservation in neonatal and paediatric surgery, the costs associated with blood transfusion and the quest for artifical blood. New chapters will be included to address blood utilization in oncology and geriatric patients.

This book functions as a comprehensive and authoritative reference book in blood transfusion and blood substitutes. It is a collection of the latest developments and the newest investigations, and individual chapters are written by world experts in the arena. The book begins with a historical review on the practice of transfusions as well as the components and physiology of blood. The following chapters cover various topics, including platelet substitutes, hemoglobin-based oxygen carriers, perfluorocarbon based oxygen carriers, and safety issues related to artificial hemoglobin. All chapters provide a bulleted highlights list to facilitate readers in mastering the main points of each individual chapter. Blood Substitutes and Oxygen Biotherapeutics is an invaluable reference book for perioperative care providers, hematologists, anesthesiologists, surgeons, obstetricians and gynecologists.

Current Trends and Future Developments on (Bio-) Membranes: Membrane Applications in Artificial Organs and Tissue Engineering reports on membrane applications in the field of biomedical engineering, ranging from artificial organs, to tissue engineering. The book offers a comprehensive review of all the current scientific developments and various applications of membranes in this area. It is a key reference text for R&D managers in industry who are interested in the development of artificial and bioartificial organs, as well as academic researchers and postgraduate students working in the wider area of artificial organs and tissue engineering. - Describes numerous bioartificial organ configurations and their relationships to membranes - Includes new innovations and solutions in the development of artificial organs with membrane components - Describes various membrane fabrication techniques for tissue engineering

This definitive volume will provide the reader with up to date information and the most recent science of the fast-evolving area of nanobiotherapeutic-based blood substitutes. Long studied, there are recent updates that make their use in patients more promising, and with one product approved for human use, many more in the pipeline. These include 2nd generations and even third generation ones, the later with enhancement of red blood cell functions. In addition, there are carefully written and referenced updates on the recent history and products in the field, complete with pathophysiologic and pharmacologic studies to validate and verify the efficacy and safety of many of these new products.

The Yearbook compiles the most recent, widespread developments of experimental and clinical research and practice in one comprehensive reference book.
