Cell and Matrix Mechanics


Book Description

Explores a Range of Multiscale Biomechanics/Mechanobiology Concepts Cell and Matrix Mechanics presents cutting-edge research at the molecular, cellular, and tissue levels in the field of cell mechanics. This book involves key experts in the field, and covers crucial areas of cell and tissue mechanics, with an emphasis on the roles of mechanical forces in cell–matrix interactions. Providing material in each chapter that builds on the previous chapters, it effectively integrates length scales and contains, for each length scale, key experimental observations and corresponding quantitative theoretical models. Summarizes the Three Hierarchical Levels of Cell Mechanics The book contains 14 chapters and is organized into three sections. The first section focuses on the molecular level, the second section details mechanics at the cellular level, and the third section explores cellular mechanics at the tissue level. The authors offer a thorough description of the roles of mechanical forces in cell and tissue biology, and include specific examples. They incorporate descriptions of associated theoretical models, and provide the data and modeling framework needed for a multi-scale analysis. In addition, they highlight the pioneering studies in cell–matrix mechanics by Albert K. Harris. The topics covered include: The passive and active mechanical properties of cytoskeletal polymers and associated motor proteins along with the behavior of polymer networks The mechanical properties of the cell membrane, with an emphasis on membrane protein activation caused by membrane forces The hierarchical organization of collagen fibrils, revealing that a delicate balance exists between specific and nonspecific interactions to result in a structure with semicrystalline order as well as loose associations The roles of matrix mechanical properties on cell adhesion and function along with different mechanical mechanisms of cell–cell interactions The effects of mechanical loading on cell cytoskeletal remodeling, summarizing various modeling approaches that explain possible mechanisms regulating the alignment of actin stress fibers in response to stretching The mechanical testing of cell-populated collagen matrices, along with theory relating the passive and active mechanical properties of the engineered tissues Cell migration behavior in 3-D matrices and in collective cell motility The role of mechanics in cartilage development The roles of both cellular and external forces on tissue morphogenesis The roles of mechanical forces on tumor growth and cancer metastasis Cell and Matrix Mechanics succinctly and systematically explains the roles of mechanical forces in cell–matrix biology. Practitioners and researchers in engineering and physics, as well as graduate students in biomedical engineering and mechanical engineering related to mechanobiology, can benefit from this work.

Cell Mechanics


Book Description

Cell mechanics is the field of study that looks at how cells detect, modify, and respond to the physical properties of the cell environment. Cells communicate with each other through chemical and physical signals which are involved in a range of process from embryogenesis and wound healing to pathological conditions such as cancerous invasion. Similar principles are also likely to be critical for success in regenerative medicine. Cell mechanics is thus central to understanding these principles. As cell mechanics draws from the fields of biology, chemistry, physics, engineering, and mathematics, this book aims not only to provide a collection of research methods, but also to develop a common language among scientists who share the interest in cell mechanics but enter the field with diverse backgrounds. To this end all of the contributing authors have sought to explain in plain language the nature of the biological problems, the rationale for the approaches, in addition to the methods themselves. In addition, to balance practical utility against conceptual advances, Cell Mechanics has intentionally included both chapters that provide detailed recipes and those that emphasize basic principles. Presents a distinctive emphasis on matrix mechanics and their interplay with cell functions Includes highly significant topics relevant to basic and translational research, as well as tissue engineering Emphasizes mechanical input and output of cells




Mechanobiology of Cell-Cell and Cell-Matrix Interactions


Book Description

Mechanobiology of Cell-Matrix Interactions focuses on characterization and modeling of interactions between cells and their local extracellular environment, exploring how these interactions may mediate cell behavior. Studies of cell-matrix interactions rely on integrating engineering, (molecular and cellular) biology, and imaging disciplines. Recent advances in the field have begun to unravel our understanding of how cells gather information from their surrounding environment, and how they interrogate such information during the cell fate decision making process. Topics include adhesive and integrin-ligand interactions; extracellular influences on cell biology and behavior; cooperative mechanisms of cell-cell and cell-matrix interactions; the mechanobiology of pathological processes; (multi-scale) modeling approaches to describe the complexity or cell-matrix interactions; and quantitative methods required for such experimental and modeling studies.







Quantum Mechanics, Cell-Cell Signaling, and Evolution


Book Description

Quantum Mechanics, Cell-Cell Signaling, and Evolution offers a detailed accounting of the latest research and theorizing on the integration of quantum physics with biological action to produce a novel perspective on evolution. The book advocates for a paradigm shift towards understanding biology and medicine causally as predictive sciences, presenting quantum mechanics and physiology as vertically integrated. The author has taken a unique approach to the question of how and why evolution occurred. The account is based on extensive knowledge of lipid physical chemistry, and its role in the evolution of the lung under the influence of hormonal effects on structure and function. The title arranges lipid biochemistry and biophysics into an integrated explanation, guiding readers from the immersion of lipids in water as the origin of life, to lung surfactant in alveolar homeostasis, and leading to a new understanding of how consciousness interacts with the laws of nature. This volume argues for a novel understanding of evolutionary processes based on fundamental science and positions itself as seeking consilience among research disciplines. Starting from the origins of the cosmos, the author proceeds through nucleosynthesis and Endosymbiosis Theory, to finally describe consciousness in relation to natural law. Offers a novel account of evolutionary mechanisms integrating quantum mechanics and cell-cell signaling Presents the latest research and theorizing on the integration of quantum physics with biological action Grounds theoretical insights in lipid physical chemistry and the evolution of the lung Details an integrated, causal account of evolution operating across physical and biological domains Argues for a paradigm shift in the way evolution is understood




The Cellular Automaton Interpretation of Quantum Mechanics


Book Description

This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft. Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory. The author gives examples of models that are classical in essence, but can be analysed by the use of quantum techniques, and argues that even the Standard Model, together with gravitational interactions, might be viewed as a quantum mechanical approach to analysing a system that could be classical at its core. He shows how this approach, even though it is based on hidden variables, can be plausibly reconciled with Bell's theorem, and how the usual objections voiced against the idea of ‘superdeterminism' can be overcome, at least in principle. This framework elegantly explains - and automatically cures - the problems of the wave function collapse and the measurement problem. Even the existence of an “arrow of time" can perhaps be explained in a more elegant way than usual. As well as reviewing the author’s earlier work in the field, the book also contains many new observations and calculations. It provides stimulating reading for all physicists working on the foundations of quantum theory.




Quantum Mechanics For Applied Physics And Engineering


Book Description

Quantum Mechanics for Applied Physics and Engineering is devoted to the use of quantum mechanics in applied physics and engineering. Topics covered include elementary quantum theory, quantum statistics and many-particle systems, and energy bands in crystals. Approximation techniques for the Schrödinger equation are also described. Comprised of seven chapters, this book opens with an overview of basic quantum mechanics and includes a discussion on wave-particle duality, probability current density, and periodic boundary conditions. Quantum statistics is then considered as a prelude to the free-electron theory of metals, along with the use of perturbation theory to evaluate modifications in free-electron theory. The following chapters explore the use of WKB approximation to deduce the transmission coefficient for electron tunneling in solids; the theory of electronic energy bands; and the application of the Schrödinger equation to the problem of the periodic potential of a crystalline solid. Examples from solid-state physics are employed to illustrate specific applications and to demonstrate the principal results that can be deduced by means of quantum theory. This monograph is written primarily for engineers and applied physicists.
