Download or read book Free Energy Calculations written by Christophe Chipot and published by Springer Science & Business Media. This book was released on 2007-01-08 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

Book excerpt: Handbook of Drug-Nutrient Interactions, Second Edition is an essential new work that provides a scientific look behind many drug-nutrient interactions, examines their relevance, offers recommendations, and suggests research questions to be explored. In the five years since publication of the first edition of the Handbook of Drug-Nutrient Interactions new perspectives have emerged and new data have been generated on the subject matter. Providing both the scientific basis and clinical relevance with appropriate recommendations for many interactions, the topic of drug-nutrient interactions is significant for clinicians and researchers alike. For clinicians in particular, the book offers a guide for understanding, identifying or predicting, and ultimately preventing or managing drug-nutrient interactions to optimize patient care. Divided into six sections all chapters have been revised or are new to this edition. Chapters balance the most technical information with practical discussions and include outlines that reflect the content; discussion questions that can guide the reader to the critical areas covered in each chapter, complete definitions of terms with the abbreviation fully defined and consistent use of terms between chapters. The editors have performed an outstanding service to clinical pharmacology and pharmaco-nutrition by bringing together a multi-disciplinary group of authors. Handbook of Drug-Nutrient Interactions, Second Edition is a comprehensive up-to-date text for the total management of patients on drug and/or nutrition therapy but also an insight into the recent developments in drug-nutrition interactions which will act as a reliable reference for clinicians and students for many years to come.

Download or read book The Biophysics of Cell Membranes written by Richard M. Epand and published by Springer. This book was released on 2017-09-25 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the modulation of biological membranes by specific biophysical properties. The readers are introduced to emerging biophysical approaches that mimick specific states (like membrane lipid asymmetry, membrane curvature, lipid flip-flop, lipid phase separation) that are relevant to the functioning of biological membranes. The first chapter describes innovative methods to mimic the prevailing asymmetry in biological membranes by forming asymmetrical membranes made of monolayers with different compositions. One of the chapters illustrates how physical parameters, like curvature and elasticity, can affect and modulate the interactions between lipids and proteins. This volume also describes the sensitivity of certain ion channels to mechanical forces and it presents an analysis of how cell shape is determined by both the cytoskeleton and the lipid domains in the membrane. The last chapter provides evidence that liposomes can be used as a minimal cellular model to reconstitute processes related to the origin of life. Each topic covered in this volume is presented by leading experts in the field who are able to present clear, authoritative and up-to-date reviews. The novelty of the methods proposed and their potential for a deeper molecular description of membrane functioning are particularly relevant experts in the areas of biochemistry, biophysics and cell biology, while also presenting clear and thorough introductions, making the material suitable for students in these fields as well.

Download or read book Voltage Gated Sodium Channels written by Peter C. Ruben and published by Springer Science & Business Media. This book was released on 2014-04-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of techniques to study ion channels have been developed since the electrical basis of excitability was first discovered. Ion channel biophysicists have at their disposal a rich and ever-growing array of instruments and reagents to explore the biophysical and structural basis of sodium channel behavior. Armed with these tools, researchers have made increasingly dramatic discoveries about sodium channels, culminating most recently in crystal structures of voltage-gated sodium channels from bacteria. These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs and toxins with which they are known to interact, acquired and inherited diseases that affect sodium channels and the techniques with which their biophysical and structural properties are studied.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph explores the relationships between cell signaling and the cytoplasmic cytoskeleton in fundamental cell processes, thus bridging the gap between two very active aspects of molecular cell biology. It covers the two main - and reciprocal - questions of these relationships: How are structure and function of the cytoskeleton affected by external signals which impinge on the cell? How does the cytoskeleton influence the cellular signaling processes which determine cell behavior?

Download or read book Ion Channel Regulation written by and published by Academic Press. This book was released on 1999-04-13 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 33 reviews the current understanding of ion channel regulation by signal transduction pathways. Ion channels are no longer viewed simply as the voltage-gated resistors of biophysicists or the ligand-gated receptors of biochemists. They have been transformed during the past 20 years into signaling proteins that regulate every aspect of cell physiology. In addition to the voltage-gated channels, which provide the ionic currents to generate and spread neuronal activity, and the calcium ions to trigger synaptic transmission, hormonal secretion, and muscle contraction, new gene families of ion channel proteins regulate cell migration, cell cycle progression, apoptosis, and gene transcription, as well as electrical excitability. Even the genome of the lowly roundworm Caenorhabditis elegans encodes almost 100 distinct genes for potassium-selective channels alone. Most of these new channel proteins are insensitive to membrane potential, yet in humans, mutations in these genes disrupt development and increase individual susceptibility to debilitating and lethal diseases.How do cells regulate the activity of these channels? How might we restore their normal function? In Ion Channel Regulation, many of the experts who pioneered these discoveries provide detailed summaries of our current understanding of the molecular mechanisms that control ion channel activity. - Reviews brain functioning at the fundamental, molecular level - Describes key systems that control signaling between and within cells - Explains how channels are used to stimulate growth and changes to activity of the nucleus and genome

Download or read book Neuronal Nicotinic Receptors written by F. Clementi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 837 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuronal nicotinic receptors are key molecules for signal transduction in a number of neuronal pathways. They are widely distributed in the brain and are known to be involved in cognitive tasks, including learning and memory, in smoking addiction and in several brain diseases, such as Alzheimer's and Parkinson's dementias, schizophrenia, and epilepsy. This book provides a comprehensive review of the field, starting with a historical perspective and dealing with the molecular structure of these receptors, their biophysical and pharmacological properties, their distribution in central and peripheral nervous systems, and their major involvement in brain functions. Particular emphasis is paid to drugs (both new and old) that are useful in the diagnosis and treatment of diseases involving neuronal nicotinic receptors. Finally, the relevance of these receptors in smoking addiction is carefully evaluated, together with future trends and the latest results.

Download or read book Cerebral and Cerebellar Cortex written by Stavros J. Baloyannis and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerebral and Cerebellar Cortex - Interaction and Dynamics in Health and Disease discusses several important issues of cerebro-cerebellar collaboration and interactions. The morphological and functional study of the cerebral and cerebellar cortices and their interaction has considerable value for interpreting the clinical phenomenology of cortical degenerations in the initial stage of the disease. In addition, the analysis of cerebro-cerebellar interactions strongly supports the concept of the close functional unity and harmonization of the brain and the cerebellum, underlining the important role that the cerebellar cortex plays in the performance of higher mental faculties, creativity, emotional processes, and homeostatic equilibrium of the human body.

Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book New Developments in Lipid Protein Interactions and Receptor Function written by K.W.A. Wirtz and published by Springer. This book was released on 2012-10-24 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute on "New Developments in Lipid-Protein Interactions and Receptor Function" was held on the Island of Spetsai, Greece, from August 16-27, 1992. This Institute was organized to bring together researchers in the field of membrane organization and dynamics with those actively involved in studies on receptor function, signal transduction mechanisms and gene regulation. 2 Presentations and discussions focussed on the regulation of intracellular Ca +-levels, on the second messengers derived from inositol lipids and on the specific phospholipase C isozymes involved in these processes. A major focus was on G-proteins and the effect of lipid anchors on their function. These principles of regulation were further discussed in the context of receptors for acetylcholine, lysophosphatidic acid and low-density lipoproteins. In addition, various aspects of the genomic regulation of cell growth and differentiation by transcription factors were presented. These topics were put into perspective by discussing the most recent developments in lipid-protein interactions, protein insertion into membranes, membrane lipid organization and lipid dynamics as mediated by phospholipid transfer proteins. This book presents the content of the major lectures and a selection of the most relevant of the most important topics posters. These proceedings offer a comprehensive account presented during the course of the Institute. The book is intended to make these proceedings accessible to a large audience.

Download or read book Mechanisms of Drug Interactions written by Patrick F. D'Arcy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years a number of excellent books have classified and detailed drug drug interactions into their respective categories, e.g. interactions at plasma protein binding sites; those altering intestinal absorption or bioavailability; those involving hepatic metabolising enzymes; those involving competition or antagonism for receptor sites, and drug interactions modifying excretory mechanisms. Such books have presented extensive tables of interactions and their management. Although of considerable value to clinicians, such publica tions have not, however, been so expressive about the individual mechanisms that underlie these interactions. It is within this sphere of "mechanisms" that this present volume specialises. It deals with mechanisms of in vitro and in vivo, drug-drug, drug food and drug-herbals interactions and those that cause drugs to interfere with diagnostic laboratory tests. We believe that an explanation of the mechanisms of such interactions will enable practitioners to understand more fully the nature of the interactions and thus enable them to manage better their clinical outcome. If mechanisms of interactions are better understood, then it may be pos sible for the researcher to develop meaningful animal/biochemical/tissue cul ture or physicochemical models to which new molecules could be exposed during their development stages. The present position, which largely relies on patients experiencing adverse interactions before they can be established or documented, can hardly be regarded as satisfactory. This present volume is classified into two major parts; firstly, pharmacoki netic drug interactions and, secondly, pharmacodynamic drug interactions.
