Free Download Bioelectrochemistry of Cells and Tissues By Victor P. Whittaker (auth.), PD Dr. Dieter Walz, Hermann Berg Ph.D., Giulio Milazzo (eds.)
1995 | 305 Pages | ISBN: 3034898908 | PDF | 8 MB
Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. The role of electric and magnetic fields in biological systems forms the focus of this second volume in the Bioelectrochemistry series. The most prominent use of electric fields is found in some fish. These species generate fields of different strengths and patterns serving either as weapons, or for the purpose of location and communication. Electrical phenomena involved in signal transduction are discussed by means of two examples, namely excitation-contraction coupling in muscles and light transduction in photoreceptors. Also examined is the role of electrical potential differences in energy metabolism and its control. Temporal and spatial changes of the potential difference across the membranes of nerve cells are carefully evaluated, since they are the basis of the spreading and processing of information in the nervous system. The dielectric properties of cells and their responses to electric fields, such as electrophoresis and electrorotation, are dealt with in detail. Finally, the effects of magnetic fields on living systems and of low-frequency electromagnetic fields on cell metabolism are also considered. Further volumes will be added to the series, which is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.

The intestine is colonized by an impressive community of commensals, that has profound effects on the immune funtions. The relationship between gut microbiota and the immune system is one of reciprocity: commensals have important contribution in nutrient processing and education of the immune system and conversely, the immune system, particularly gut-associated lymphoid tissues plays a key role in shaping the repertoire of gut microbiota.

Free Download Cardiac Reconstructions with Allograft Tissues By Richard A. Hopkins MD (auth.)
2005 | 656 Pages | ISBN: 0387949623 | PDF | 22 MB
Cryopreserved allograft tissues are now standard materials for the reconstructive cardiac surgeon. Since publication of the first edition ("Cardiac Reconstructions with Allograft Valves") in 1989, the field has progressed dramatically with increased clinical use of cardiovascular allograft tissues, with the development of new surgical techniques, and with advances in the understanding of the fundamentals of valve transplantation biology and cryopreservation. As a result, over two-thirds of the present volume represents new material. Fifty-six authors bring their expertise to thirteen comprehensive, lavishly illustrated sections which discuss the principles of the use of homograft valves, major clinical series of homograft valves for both left and right ventricular outflow tracts, cryopreserved allograft tissue for cardiac reconstruction, cell biology of heart valve leaflets, cryobiology of heart valve preservation, morphological, biochemical, and explant pathology studies of allograft heart valves, allograft valve banking, as well as detailed explanation of surgical techniques for valve and root methods for left and right ventricular outflow tract reconstructions, the Ross operation and variants, and complex reconstructions. A final section presents potential future directions for the field. Over 400 illustrations, created expressly for this book, depict the surgical techniques from the perspective of the surgeon standing at the operating table. All surgeons performing pediatric and/or adult valve replacements and reconstructive cardiac surgeries will benefit from the described methods. Cardiothoracic residents and cardiologists will also find the text useful. It will provide the surgeon with an enhanced understanding of the biological and material properties of allografts and increased familiarity with the range of surgical techniques applicable for the use of these valves, particularly in the successful management of challenging cardiac reconstructions.>

Free Download Engineering of Human Tissues and Implants: An Evolutionary Approach to Implant Design
English | 2024 | ISBN: 1032399023 | 217 Pages | PDF (True) | 12 MB
Engineering of Human Tissues and Implants: An Evolutionary Approach to Implant Design provides basic scientific information on the evolutionary design of tissues and organs that are a result of living in a gravitational field. Much of the useful information that is available for the design of implants is based on tissue structure and function derived from light and electron microscopy observations. However, this information is not enough for developing new designs of implants and medical devices since much of the biological response to implants is based on understanding the biological control systems and mechanotransduction that drive many of the responses seen with implanted devices. The book also introduces mechanotransduction as it relates to implant design with an overview of materials and their use in applications that include those materials designed to treat wounds, burns, facial, hernial, ophthalmic, oral, cardiovascular, and tendon/ligaments.

This book presents experimental investigations and digital image processing, highlighting the interaction of polarized radiation with phase-inhomogeneous and optically anisotropic biological layers. The promising and efficient use of vector-parametric description of the formation of polarization-inhomogeneous object fields is noted. Applications of a set of Mueller-matrix polarimetry methods are highlighted. The book includes- structural and logical scheme of multi-parameter (singular, interference and layer-by-layer Stokes-polarimetric), polarization-correlation study of the structure of distributions of the number of singularities, maps of local contrast of interference distributions and layer-by-layer maps of microscopic polarization azimuth and ellipticity; determination of relationships between changes in the magnitude of statistical parameters characterizing polarization-correlation distributions and pathology of prostate tumors.

Free Download Cardiovascular Solid Mechanics: Cells, Tissues, and Organs by Jay D. Humphrey
English | PDF | 2002 | 766 Pages | ISBN : 0387951687 | 74.3 MB
The vitality of the cardiovascular system, which consists of the heart, vas culature, and blood, depends on its response to a host of complex stimuli, including biological, chemical, electrical, mechanical, and thermal. The focus of this book, however, is on the response of the heart and arteries to mechanical loads from the perspective of nonlinear solid mechanics. Through my own research in this field, I have come to realize that study ing the complex responses of cardiovascular cells, tissues, and organs nec essarily requires a combined theoretical, experimental, and computational approach. Theory is needed to guide the performance and interpretation of experiments as well as to synthesize the results; experiment is needed to study the responses of the system to well-controlled loads and to test can didate hypotheses and theories; and due to the geometric and material non linearities inherent to cardiovascular mechanics, computation is needed to analyze data as well as to solve boundary and initial value problems that correspond to either experimental or in vivo conditions. One of the primary goals of this book is to introduce together basic analytical, experimental, and computational methods and to illustrate how these methods can and must be integrated to gain a more complete understanding of the bio mechanics of the heart and vasculature. Despite the focus on cardiovascu lar mechanics, the fundamental methods, indeed many of the specific results, are generally applicable to many different soft tissues.
