Total joint arthroplasty is the primary intervention in the treatment of end-stage osteoarthritis. Despite the high success rate, in some patients, the replacement will fail during their lifetime requiring a revision of the implant. These revisions are strenuous for the patient and costly for health care. Joint replacement at a younger age, in combination with a more active lifestyle, increases the need for an early revision of the joint prosthesis. The main reason for revision surgeries is aseptic loosening, a condition where the prosthesis is loosening due to bone degradation at the peri-prosthetic interface in the absence of infections. The most well-established pathological mechanism for...
This concise yet comprehensive treatment of the effects of spaceflight on biological systems includes issues at the forefront of life sciences research, such as gravitational biology, immune system response, bone cell formation and the effects of radiation on biosystems. Edited by a leading specialist at the European Space Agency (ESA) with contributions by internationally renowned experts, the chapters are based on the latest space laboratory experiments, including those on SPACELAB, ISS, parabolic flights and unmanned research satellites. An indispensable source for biologists, medical researchers and astronautics experts alike. The results of Space flight experiments, ground controls and flight simulations pave the way for a better understanding of gravity reactions in various organisms down to molecular mechanisms. This publication marks also the beginning of a new Space flight era with the construction and exploitation of the International Space Station (ISS) which provides a platform for an in-depth continuation of experiments under weightlessness in Low Earth Orbit and beyond.
This book focuses on the systems biomechanics of bone remodeling that provide a multiscale platform for bone adaptation, spanning the cellular, tissue, and organ levels. The mathematical model explained in each section provides concrete examples of in silico approaches for bone adaptation. It will be immensely useful for readers interested in bone morphology and metabolism and will serve as an effective bridge connecting mechanics, cellular and molecular biology, and medical sciences. These in silico approaches towards exploring the mechanisms by which the functioning of dynamic living systems is established and maintained have potential for facilitating the efforts of graduate students and young researchers pioneering new frontiers of biomechanics.
Research into the use of calcium phosphates in the development and clinical application of biomedical materials has been a significantly diverse activity conducted by a wide range of scientists, engineers, and medical practitioners, among others. The field of research in this area can, hence, be truly defined as interdisciplinary, and much interesting work leading to imaginative and innovative solutions for the improvement of health outcomes continues to be generated. It has been the intention of this Special Issue to summarise a number of current topical research advances in this area, as well as to review the important area of calcium phosphate-based biomaterials, namely, composites of hydroxyapatite with carbon-based materials. The scientific papers contained in this Special Issue report on advances in the areas of dental-based materials science, bone cements, use of biomaterials created from natural sources, influences of added agents such as adipose stem cells and statins on bioactivity as well as surface influences on electrical potential of biomaterials and uses of glow discharge methods to remove impurities from biomaterial surfaces.
The last decade has seen a tremendous advance in our understanding of bone biology. The genes responsible for the majority of rare inherited bone disorders have been identified and much progress has been made in the identification of genes in polygenic disorders such as Paget’s disease and complex multigene diseases such as osteoporosis. Transgenic technology has identified further genes, sometimes unexpectedly, with profound effects on bone. This wealth of new genetic information will undoubtedly lead to extensive cell biological studies to understand the mechanisms by which these gene products affect bone mass and bone strength. In Bone Research Protocols a catalogue of protocols has been assembled to perform such mechanistic studies. In the tradition of the Methods in Molecular Medicine series, the chapters are practical laboratory protocols that should enable the reader to carry out the techniques from scratch. To our knowledge this is the first time such a truly practical manual on well-established bone methods has been assembled, and this volume aims to be complementary to and follow on from the more theoretical Methods in Bone Biology, edited by Arnett and Henderson (1).
The gold standard for the treatment of nonunions was set by Weber and Cech in the early 1970s. With this new book the Editors René K Marti and Peter Kloen provide a comprehensive update on the state-of-the-art treatment of nonunions. More than 130 case descriptions are included in the unique cases section; the core of this collection represents 40 years of René Marti's personal experience in nonunion treatment, demonstrating the principle "technique over technology". The editors have also carefully selected additional cases, contributed by several experts in nonunion treatment. Each case provides step-by-step descriptions of case history, preoperative planning, surgical approach, reduction, fixation, rehabilitation, and finally pitfalls and pearls. Hundreds of full-color pictures, precise illustrations, and x-rays demonstrate the significant steps in nonunion treatment. In the principles preceding the case presentations relevant information on evolution, basic science aspects, nonoperative treatment, bone graft, as well as infected nonunions is provided. The guidelines and solutions presented for the management of nonunions support orthopedic and trauma surgeons worldwide.
Lysosomes are membrane-surrounded organelles which are present in all animal cells. The importance of this organelle is underlined by an increasing number of human diseases, which are associated with an impaired function of the lysosomal compartment. This book summarizes the current state-of-the art knowledge about this unique organelle. It addresses the biogenesis of this compartment, the transport of lysosomal proteins, the role of the lysosomal membrane in lysosomal stability and transport, the function of lysosomal proteases and hydrolases, lysosomal storage disorders, and new concepts on how to treat these diseases. In addition to these classical topics, new insights into lysosomal functions are covered by chapters dealing with specialized lysosomes involved in bone resorption and plasma membrane repair, the lysosomal transciptome, and proteome and the emerging role of lysosomes in special forms of autophagy. This book will provide readers with a comprehensive overview into how this fascinating organelle works and how research in the field is developing.
