Book Description
This volume is intended to complete the Cell Chemistry and physiology module. It is about how the traditional boundaries of cell chemistry and physiology are being erased by molecular biology. We do not think it necessary to elaborate on this theme, particularly since the body of core knowledge found in this volume brings us a stage closer to answering the question, "what makes cell biology into a new discipline?"The first part of the volume deals with the chemistry of actin and myosin and is followed by chapters on cell motility, ATP synthesis in muscle, and contraction in smooth and skeletal muscle. Here the reader is immediately made aware of the contributions molecular biology is making to our understanding of the molecular mechanisms underlying muscle contraction. It is perhaps enough to point out that Huxley's concept of the cross-bridge cycle and generation of force can now be explained in molecular terms. Topics such as muscle fatigue and muscle disorders, as well as malignant hyperthermia are bound to arouse active learning in the student and set the stage for problem-based learning.Most medical students look askance at thermobiology. We think this is a mistake; hence, we have included a section dealing with this subject. This brings us to the chapter on the heat shock response, which at the very outset makes clear that many stressors besides heat are known to result in heat shock gene expression. Many of the heat shock proteins occur in unstressed cells and some of them behave as chaperones. These proteins also reach high levels in a wide range of diseases including neurodegenerative disorders. Whether certain diseases are the result of mutations in the heat shock genes is not yet known. As will be appreciated, much of the work done in this field involved the use of cultured cells. Animal cells in culture are the subject of the last chapter.

Book Description
This volume illustrates the extent to which the traditional distinction between biochemical and physiological processes is being obliterated by molecular biology. It can hardly be doubted that the revolution in cell and molecular biology is leading to core knowledge that provides an outline of the integrative and reductionist approach. We view this as the beginning of a new era, that of the integration of learning.As in the preceding volumes, the choice of topics has been deliberate not only because of the need to keep the volume within reasonable bounds but also because of the need to avoid information over-load. Several relevant topics are dealt with in other modules; for example, the role of G proteins in transmembrane signalling is covered in the Membranes and Cell Signalling module (i.e., Volume 7). Omissions are of course inevitable but they are minor. A case in point is the subject of phosphatases, the treatment of which does not take into account calcineurin. One of the key functions of this Ca2+ -activated protein phosphatase that is also regulated by calmodulin is to desphosphorylate voltage-dependent Ca2+ channels. The mere recognition of such omissions before or after consulting textbooks and journals should be a spur to a more complete discussion by the student of the subject in a small group teaching setting.

Book Description
This text is the successor volume to Biophysical Plant Physiology and Ecology (W.H. Freeman, 1983). The content has been extensively updated based on the growing quantity and quality of plant research, including cell growth and water relations, membrane channels, mechanisms of active transport, and the bioenergetics of chloroplasts and mitochondria. One-third of the figures are new or modified, over 190 new references are incorporated, the appendixes on constants and conversion factors have doubled the number of entries, and the solutions to problems are given for the first time. Many other changes have emanated from the best laboratory for any book, the classroom.· Covers water relations and ion transport for plant cells; diffusion, chemical potential gradients, solute movement in and out of plant cells· Covers interconnection of various energy forms; light, chlorophyll and accessory photosynthesis pigments, ATP and NADPH· Covers forms in which energy and matter enter and leave a plant; energy budget analysis, water vapor and carbon dioxide, water movement from soil to plant to atmosphere

Book Description
Bacterial Physiology focuses on the physiology and chemistry of microorganisms and the value of bacterial physiology in the other fields of biology. The selection first underscores the chemistry and structure of bacterial cells, including the chemical composition of cells, direct and indirect methods of cytology, vegetative multiplication, spores of bacteria, and cell structure. The text then elaborates on inheritance, variation, and adaptation and growth of bacteria. The publication reviews the physical and chemical factors affecting growth and death. Topics include hydrogen ion concentration and osmotic pressure; surface and other forces determining the distribution of bacteria in their environment; dynamics of disinfection and bacteriostasis; bacterial resistance; and types of antibacterial agents. The text also ponders on the anaerobic dissimilation of carbohydrates, bacterial oxidations, and autotrophic assimilation of carbon dioxide. The selection is a dependable reference for readers interested in bacterial physiology.

Book Description
Plant cell walls are complex, dynamic cellular structures essential for plant growth, development, physiology and adaptation. Plant Cell Walls provides an in depth and diverse view of the microanatomy, biosynthesis and molecular physiology of these cellular structures, both in the life of the plant and in their use for bioproducts and biofuels. Plant Cell Walls is a textbook for upper-level undergraduates and graduate students, as well as a professional-level reference book. Over 400 drawings, micrographs, and photographs provide visual insight into the latest research, as well as the uses of plant cell walls in everyday life, and their applications in biotechnology. Illustrated panels concisely review research methods and tools; a list of key terms is given at the end of each chapter; and extensive references organized by concept headings provide readers with guidance for entry into plant cell wall literature. Cell wall material is of considerable importance to the biofuel, food, timber, and pulp and paper industries as well as being a major focus of research in plant growth and sustainability that are of central interest in present day agriculture and biotechnology. The production and use of plants for biofuel and bioproducts in a time of need for responsible global carbon use requires a deep understanding of the fundamental biology of plants and their cell walls. Such an understanding will lead to improved plant processes and materials, and help provide a sustainable resource for meeting the future bioenergy and bioproduct needs of humankind.

Book Description
Nitric oxide (NO) is a gas that transmits signals in an organism. Signal transmission by a gas that is produced by one cell and which penetrates through membranes and regulates the function of another cell represents an entirely new principle for signaling in biological systems. NO is a signal molecule of key importance for the cardiovascular system acting as a regulator of blood pressure and as a gatekeeper of blood flow to different organs. NO also exerts a series of other functions, such as acting a signal molecule in the nervous system and as a weapon against infections. NO is present in most living creatures and made by many different types of cells. NO research has led to new treatments for treating heart as well as lung diseases, shock, and impotence. Scientists are currently testing whether NO can be used to stop the growth of cancerous tumors, since the gas can induce programmed cell death, apoptosis. This book is the first comprehensive text on nitric oxide to cover all aspects--basic biology, chemistry, pathobiology, effects on various disease states, and therapeutic implications. - Edited by Nobel Laureate Louis J. Ignarro, editor of the Academic Press journal, Nitric Oxide - Authored by world experts on nitric oxide - Includes an overview of basic principles of biology and chemical biology - Covers principles of pathobiology, including the nervous system, cardiovascular function, pulmonary function, and immune defense
