This book introduces the clinical application of artificial liver system (ALS) in hepatic failure. It has been widely used in clinics aiming to provide temporary support of liver function while maintaining extra-hepatic function in patients with liver failure. This work comprehensively summarizes the progress of livers and artificial liver, for example, the principle and implementation of Li-ALS, cell transplantation and the combined application of artificial liver and liver transplantation. It will be helpful for clinicians to implement artificial liver treatment to save the lives of patients with hepatic failure.

Continuing progress has been made since the first edition of Artificial Liver Support was published. Liver transplantation has however become an estab lished therapy for a relatively small number of patients who remain patients for life. There therefore continues to be a great need for the development of other forms of artificial liver support. Improved intensive care utilizing improved plasma exchange, dialysis, sclerotherapy, and intracranial pressure monitoring have improved survival in fulminant hepatic failure. Progress has also been made in lipid membrane detoxification, in cell cultures, and in cell transplantation, and the isolation of various liver cell growth factors has led to deep insight into the mechanisms of liver regeneration. This book gives the clinician and the researcher detailed information about established new methods of clinic work and laboratory research, and describes new experimental approaches indicating the direction of future research. G. BRUNNER M. Mno Preface to the First Edition The regenerative capacity of the liver cell is almost unlimited. Therefore after acute liver damage, be it viral, toxic, hypoxic, or surgical in origin, restitutio ad integrum is the usual outcome. In two forms of liver disease, however, this is not the case: in fulminant hepatic failure, liver regeneration often is not fast enough to keep the organism alive; in end-stage cirrhosis, regeneration is disturbed by a hypertrophic architecture of fibrotic tissue. For these extreme forms of liver disease and for critical situations before and after liver surgery, artificial liver support is needed.

A comprehensive reference and teaching aid on tissue engineering—covering everything from the basics of regenerative medicine to more advanced and forward thinking topics such as the artificial liver, bladder, and trachea Regenerative medicine/tissue engineering is the process of replacing or regenerating human cells, tissues, or organs to restore or establish normal function. It is an incredibly progressive field of medicine that may, in the near future, help with the shortage of life-saving organs available through donation for transplantation. Introduction to Tissue Engineering: Applications and Challenges makes tissue engineering more accessible to undergraduate and graduate students alike. It provides a systematic and logical eight-step process for tissue fabrication. Specific chapters have been dedicated to provide in-depth principles for many of the supporting and enabling technologies during the tissue fabrication process and include biomaterial development and synthesis, bioreactor design, and tissue vascularization. The tissue fabrication process is further illustrated with specific examples for liver, bladder, and trachea. Section-coverage includes an overall introduction of tissue engineering; enabling and supporting technologies; clinical applications; and case studies and future challenges. Introduction to Tissue Engineering: Presents medical applications of stem cells in tissue engineering Deals with the effects of chemical stimulation (growth factors and hormones) Covers current disease pathologies and treatment options (pacemakers, prosthesis) Explains bioengineering, design and fabrication, and critical challenges during tissue fabrication Offers PowerPoint slides for instructors Features case studies and a section on future directions and challenges As pioneering individuals look ahead to the possibility of generating entire organ systems, students may turn to this text for a comprehensive understanding and preparation for the future of regenerative medicine.

Developments in tissue engineering for human medicine are increasing rapidly. Advances in stem cell biology, biomaterials science and scaffold design underpin this emerging science. An equally important facet of this field is the rational design and operation of bioreactors to control the nascent tissue growth. For the first time in a single volume, the design, characterisation and operation of the bioreactor system in which the tissue is grown is detailed. Bioreactors for Tissue Engineering presents an overall picture of the current state of knowledge in the engineering of bioreactors for several tissue types (bone, cartilage, vascular), addresses the issue of mechanical conditioning of the tissue, and describes the use of techniques such as MRI for monitoring tissue growth. This unique volume is dedicated to the fundamentals and application of bioreactor technology to tissue engineering products. Not only will it appeal to graduate students and experienced researchers in tissue engineering and regenerative medicine, but also to tissue engineers and culture technologists, academic and industrial chemical engineers, biochemical engineers and cell biologists who wish to understand the criteria used to design and develop novel systems for tissue growth in vitro.

This second edition of Biomaterials Science leads the field by providing a balanced, insightful view of biomaterials. Contributions from pre-eminent researchers and practitioners from diverse academic and professional backgrounds have been integrated into a cohesive curriculum which includes pertinent principles of cell biology, immunology and pathology focusing on the clinical uses of biomaterials as components of implants, devices, and artificial organs, and their uses in biotechnology. The materials science and engineering of synthetic and natural biomaterials and the characterization of their physical, chemical, biochemical and surface properties, and mechanisms and evaluation of interactions with tissue, are also addressed in detail.

This book explains, using the example of endovascular intervention, the development of in vitro simulators for biomedical applications based on the scientific context in the robotics area and the explanation of the medical procedure to be simulated. It presents modeling methods for in vitro representation of human tissue and for representing tissue integrity during endovascular surgery simulation. Additionally, applications of this in vitro vasculature modeling technology are presented: flow control for human blood pressure simulation, computer fluid dynamics simulations using vasculature morphology, catheter insertion robot control and vasculature imaging based on magnetic trackers, and tailor-made scaffolds for blood vessel regeneration.

Hepatitis is an inflammation of the liver brought on by viral infections, autoimmune diseases, alcohol abuse, exposure to toxins, or other causes.

Artificial organs may be considered as small-scale process plants, in which heat, mass and momentum transfer operations and, possibly, chemical transformations are carried out. This book proposes a novel analysis of artificial organs based on the typical bottom-up approach used in process engineering. Starting from a description of the fundamental physico-chemical phenomena involved in the process, the whole system is rebuilt as an interconnected ensemble of elemental unit operations. Each artificial organ is presented with a short introduction provided by expert clinicians. Devices commonly used in clinical practice are reviewed and their performance is assessed and compared by using a mathematical model based approach. Whilst mathematical modelling is a fundamental tool for quantitative descriptions of clinical devices, models are kept simple to remain focused on the essential features of each process. Postgraduate students and researchers in the field of chemical and biomedical engineering will find that this book provides a novel and useful tool for the analysis of existing devices and, possibly, the design of new ones. This approach will also be useful for medical researchers who want to get a deeper insight into the basic working principles of artificial organs.

Biomaterials are composed of metallic materials, ceramics, polymers, composites and hybrid materials. Biomaterials used in human beings require safety regulations, toxicity, allergic reaction, etc. When used as implantable materials their biological compatibility, biomechanical compatibility, and morphological compatibility must be acessed. This book explores the design and requirements of biomaterials for the use in implantology.

Acute organ damage and the ensuing multiple organ failure are the result of a pathophysiological process involving various cytokines. Once activated, these proteins cannot be eliminated even when the kidneys function at their maximum capacity. To counteract this mechanism, researchers in Japan have developed an innovative concept employing blood purification to remove the overwhelming cytokines. This book describes the use of hemodiafiltration to inhibit the cytokine storms which cause serious organ damage in patients with septic shock. Moreover, the technical construction of the blood purification system, which includes various machines, devices, membranes, fluids, etc., is explained in detail. Finally, leading experts discuss the concept of continuous renal replacement therapy as the standard care in critically ill patients with severe acute kidney injury. Describing the current state of acute blood purification, this publication provides new impulses and opens new avenues in the treatment of acute organ damage.
