Book Description
Protein sorting and trafficking are regulated by well-conserved mechanisms. These allow a distinctive set of resident proteins to be present in the correct subcellular organelle, which is required for proper cell functioning. Voltage-gated ion channels, as responsible for cardiomyocyte action potential, must be properly localized. They participate in cell excitability and electrical coupling, ensuring uninterrupted and rhythmic heart beating. Ion channel complexes comprise one or more pore-forming α subunits, associated β subunits, and additional proteins. Channel localization and function are regulated by the β subunits and associated proteins, such as cytoskeletal elements, cell-adhesion molecules, and adaptors. These influence protein targeting, anchoring, and retention in specific surface domains along the cardiomyocyte sarcolemma, such as intercalated discs, T-tubules, or the lateral membrane. Alterations in ion channel trafficking are the cause of channelopathies associated with inherited arrhythmias leading to sudden death. An outstanding question is how these molecular alterations lead to disease. In this volume, scientists share their vision to understand how cardiac ion channel trafficking is regulated and how it may become altered, leading to channelopathies that often turn into deadly arrhythmias. Data generated can be translated to a clinical context, hopefully turning into approaches to help prevention and treatment, which is of utmost importance, both medically and socially.

Book Description
A well-adjusted expression of cardiac ion channels at the sarcolemma is of crucial importance for normal action potential formation and thus cardiac function. The cellular processes that transport channel proteins from the endoplasmic reticulum towards specified regions on the sarcolemmal membrane, and subsequently take them from the plasma membrane to the protein degradation machinery are commonly known as trafficking. The research field recognizes that aberrant channel trafficking stands at the basis of many congenital and acquired arrhythmias. The collection of papers in this eBook provides state-of-the-art insight into the world of ion channel trafficking research.

Book Description
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.

Book Description
In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR. Anesthetic Pharmacology: Basic Principles and Clinical Practice, 2nd edition, is an outstanding therapeutic resource in anesthesia and critical care: Section 1 introduces the principles of drug action, Section 2 presents the molecular, cellular and integrated physiology of the target organ/functional system and Section 3 reviews the pharmacology and toxicology of anesthetic drugs. The new Section 4, Therapeutics of Clinical Practice, provides integrated and comparative pharmacology and the practical application of drugs in daily clinical practice. Edited by three highly acclaimed academic anesthetic pharmacologists, with contributions from an international team of experts, and illustrated in full colour, this is a sophisticated, user-friendly resource for all practitioners providing care in the perioperative period.

Book Description
A comprehensive review of all the latest developments in cardiac electrophysiology, focusing on both the clinical and experimental aspects of ventricular repolarization, including newly discovered clinical repolarization syndromes, electrocardiographic phenomena, and their correlation with the most recent advances in basic science. The authors illuminate the basic electrophysiologic, molecular, and pharmacologic mechanisms underlying ventricular repolarization, relate them to specific disease conditions, and examine the future of antiarrhythmic drug development based on both molecular and electrophysiological properties. They also fully review the clinical presentation and management of specific cardiac repolarization conditions.

Book Description
Ion channel dysfunction in humans leads to impairment of the excitable processes necessary for the normal function of several tissues, such as muscle and brain. It follows that an increasing number of human diseases have been associated with malfunctioning ion channels, many of which have a genetic component. This volume of Advances in Genetics presents a broad and comprehensive overview of the inherited channelopathies in humans, including clinical, genetic and molecular aspects of these conditions. Keeping true to the scope of the serial, novel genomic and modeling research approaches and a review of potential therapeutic approaches for each of these conditions are also incorporated.
