Book Description
Force plays a fundamental role in the regulation of biological processes. Cells can sense the mechanical properties of the extracellular matrix (ECM) by applying forces and transmitting mechanical signals. They further use mechanical information for regulating a wide range of cellular functions, including adhesion, migration, proliferation, as well as differentiation and apoptosis. Even though it is well understood that mechanical signals play a crucial role in directing cell fate, surprisingly little is known about the range of forces that define cell-ECM interactions at the molecular level. ...

Book Description
Structure and Function of the Extracellular Matrix: A Multiscale Quantitative Approach introduces biomechanics and biophysics with applications to understand the biological function of the extracellular matrix in health and disease. A general multiscale approach is followed by investigating behavior from the scale of single molecules, through fibrils and fibers, to tissues of various organ systems. Through mathematical models and structural information, quantitative description of the extracellular matrix function is derived with tissue specific details. The book introduces the properties and organization of extracellular matrix components and quantitative models of the matrix, and guides the reader through predicting functional properties. This book integrates evolutionary biology with multiscale structure to quantitatively understand the function of the extracellular matrix. This approach allows a fresh look into normal functioning as well as the pathological alterations of the extracellular matrix. Professor Suki’s book is written to be useful to undergraduates, graduate students, and researchers interested in the quantitative aspects of the extracellular matrix. Researchers working in mechanotransduction, respiratory and cardiovascular mechanics, and multiscale biomechanics of tendon, cartilage, skin, and bone may also be interested in this book. Examines the evolutionary origins and consequences of the extracellular matrix Delivers the first book to quantitatively treat the extracellular matrix as a multiscale system Presents problems and a set of computational laboratory projects in various chapters to aid teaching and learning Provides an introduction to the properties and organization of the extracellular matrix components

Book Description
The skeleton plays essential physiological functions throughout life from structural support and movement for the entire body, to storage of minerals and hematopoiesis, as well as endocrine functions. Skeletal integrity is maintained by the efficient remodeling and repair abilities of bone tissue that involves multiple skeletal stem/progenitor cell (SSPC) populations within bone compartments. These populations change their properties during development, growth and aging and can be affected by disease and trauma. SSPCs also interact with bone marrow, blood vessels, nerves, and adjacent soft tissues. The close communication between various skeletal and extra-skeletal cell populations is required for bone maintenance and function, and during bone regeneration following injury or trauma. Tremendous advances have been made in the past decade on the characterization of SSPCs that support skeletal regeneration. Yet, we still do not fully understand the basic cellular and molecular mechanisms underlying the high regenerative potential of bone and how disease or trauma can reduce SSPC functions and lead to impaired healing.

Book Description
This book provides the readers with an up-to-date review of the design, structure and function of a representative selection of fibrous proteins in both health and disease. The importance of the α-helical coiled coil, a conformational motif based on the heptad repeat in the amino acid sequence of all α-fibrous proteins (and parts of some globular proteins) is underlined by three Chapters devoted to its design, structure, function and topology. Specific proteins covered in the text and which depend on the coiled coil for their structure and function, include the intermediate filament proteins, tropomyosin, myosin, paramyosin, fibrin and members of the spectrin superfamily. Also described are fibrous proteins based on the β-pleated sheet and collagen conformations. Recombinant structural proteins, especially of silk and collagen, are discussed in the context of developing new biomaterials with varied applications. Established researchers and postgraduate students in the fields of protein chemistry, biochemistry and structural biophysics will find Fibrous Proteins: Structures and Mechanisms to be an invaluable collection of topical reviews that describe the basic advances made in the field of fibrous proteins over the past decade. This book, written by recognized authorities in the field, provides a clear account of the current status of fibrous protein research and, in addition, establishes the basis for deciding the most appropriate directions for future activity, including the applications of protein engineering and the commercial exploitation of new biomaterials.

Book Description
This book gathers relatively recent and significant topics in the field of ion channel research. Ion channels form the molecular basis for membrane excitability in cells present in the cardiovascular and nervous systems. In many non-excitable cells, ion channels contribute to diverse physiological functions, including the secretion of signaling compounds like hormones and insulin, cell volume regulation, intracellular signaling, especially Ca2+ signaling, etc. Many human diseases have been attributed to abnormal channel functions and defective membrane expression of channel proteins. On the other hand, ion channels are excellent models for studying protein biophysics, especially the allosteric regulation of protein function by miscellaneous stimuli. Therefore, research on ion channels carries significant meaning for the understanding of basic protein biophysics and diverse physiological functions. Such vital information also assists in developing novel and effective treatments for related human diseases. This book provides graduates and scientists in both basic and clinical levels a comprehensive understanding of cutting-edge advances and a useful and stimulating platform for tackling their own questions about ion channels.

Book Description
This book is the third volume in this highly successful series. Since the first volume in 1989 and the second in 1993, many exciting developments have occurred in the development of simulation techniques and their application to key biological problems such as protein folding, protein structure prediction and structure-based design, and in how, by combining experimental and theoretical approaches, very large biological systems can be studied at the molecular level. This series attempts to capture that progress. Volume 3 includes contributions that highlight developments in methodology which enable longer and more realistic simulations (e.g. multiple time steps and variable reduction techniques), a study of force fields for proteins and new force field development, a novel approach to the description of molecular shape and the use of molecular shape descriptors, the study of condensed phase chemical reactions, the use of electrostatic techniques in the study of protonation, equilibria and flexible docking studies, structure refinement using experimental data (X-ray, NMR, neutron, infrared) and theoretical methods (solvation models, normal mode analysis, MD simulations, MC lattice dynamics, and knowledge-based potentials). There are several chapters that show progress in the development of methodologies for the study of folding processes, binding affinities, and the prediction of ligand-protein complexes. The chapters, contributed by experienced researchers, many of whom are leaders in their field of study, are organised to cover developments in: simulation methodology the treatment of electrostatics protein structure refinement the combined experimental and theoretical approaches to the study of very large biological systems applications and methodology involved in the study of protein folding applications and methodology associated with structure-based design.

Book Description
Nanosensors and nanorobots are not science fiction but part of nanomedicine, the newest direction in medicine. After touring medical history and defining molecular nanotechnology as the atomic-level control of molecular structures to create precisely targeted medical procedures, Freitas (Institute for Molecular Manufacturing, Palo Alto, CA) details such topics as molecular transport and device applications but leaves ethical debates to others. Appends data on nanodevice design, and human blood and cell types; and a 36-page glossary. Part of a three-volume work, due to be available online.

Book Description
This important volume contains selected papers and extensive commentaries on laser trapping and manipulation of neutral particles using radiation pressure forces. Such techniques apply to a variety of small particles, such as atoms, molecules, macroscopic dielectric particles, living cells, and organelles within cells. These optical methods have had a revolutionary impact on the fields of atomic and molecular physics, biophysics, and many aspects of nanotechnology.In atomic physics, the trapping and cooling of atoms down to nanokelvins and even picokelvin temperatures are possible. These are the lowest temperatures in the universe. This made possible the first demonstration of Bose-Einstein condensation of atomic and molecular vapors. Some of the applications are high precision atomic clocks, gyroscopes, the measurement of gravity, cryptology, atomic computers, cavity quantum electrodynamics and coherent atom lasers.A major application in biophysics is the study of the mechanical properties of the many types of motor molecules, mechanoenzymes, and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Unique in vitro and in vivo assays study the driving forces, stepping motion, kinetics, and efficiency of these motors as they move along the cell's cytoskeleton. Positional and temporal resolutions have been achieved, making possible the study of RNA and DNA polymerases, as they undergo their various copying, backtracking, and error correcting functions on a single base pair basis.Many applications in nanotechnology involve particle and cell sorting, particle rotation, microfabrication of simple machines, microfluidics, and other micrometer devices. The number of applications continues to grow at a rapid rate.The author is the discoverer of optical trapping and optical tweezers. With his colleagues, he first demonstrated optical levitation, the trapping of atoms, and tweezer trapping and manipulation of living cells and biological particles.This is the only review volume covering the many fields of optical trapping and manipulation. The intention is to provide a selective guide to the literature and to teach how optical traps really work.
