To produce energy, aerobic organisms transform oxygen molecules into water. This reductive mechanism yields toxic radical intermediates, collectively known as reactive oxygen species (ROS). Paradoxically, these physiological processes entail the production of potentially damaging species. Evolution has turned this apparent disadvantage into an opportunity for transmitting information. As a result, redox signaling within the cell is an efficient exquisitely organized process. A key element for its regulation is the physical separation of sources and targets into different cell compartments. Peroxiporins, H2O2 transporting proteins spanning biological membranes, distribute the signal from emitters to receptors. Thus, these channels are strategically situated in the thin line between life and death, guaranteeing adequate but safe signaling. Key Features: - Provides a brief history of the discovery and characterization of peroxiporins - Reviews key findings on hydrogen peroxide transport across biological membranes - Discusses the cartography of redox signaling in crowded cells - Includes lavish illustrations and comprehensive images to facilitate teaching - Highlights recent findings, outstanding controversies and open questions

These proceedings of the 2018 XIII International Symposium on Spermatology focus on comparative biology, and encourages discussion and the exchange of ideas. The aim of this Symposium was to provide a unique opportunity and bring together scientists from a wide spectrum of research fields – human, domestic animals and other mammals, vertebrates, insects, and plants. The underlying focus is on the function of the spermatozoon – a common feature for sexual reproduction, but extremely varied. By exploring the variability, a better understanding of male reproductive functions can develop. These proceedings address the mechanisms of physiology and pathophysiology, rather than diagnosis and treatment. The symposium featured keynote lectures by invited speakers, followed by presentations on specific aspects of the general topic of the session. Experimental studies are given priority over clinical studies of patient populations. The proceedings comprise both keynote speakers' texts and selected free communications. Posters were considered for publication in the proceedings, and the volume includes exhibited materials on the work of prominent spermatologists, highlighting their important past achievements in the field.

Ascorbic acid (AsA), vitamin C, is one of the most abundant water-soluble antioxidant in plants and animals. In plants AsA serves as a major redox buffer and regulates various physiological processes controlling growth, development, and stress tolerance. Recent studies on AsA homeostasis have broadened our understanding of these physiological events. At the mechanistic level, AsA has been shown to participate in numerous metabolic and cell signaling processes, and the dynamic relationship between AsA and reactive oxygen species (ROS) has been well documented. Being a major component of the ascorbate-glutathione (AsA-GSH) cycle, AsA helps to modulate oxidative stress in plants by controlling ROS detoxification alone and in co-operation with glutathione. In contrast to the single pathway responsible for AsA biosynthesis in animals, plants utilize multiple pathways to synthesize AsA, perhaps reflecting the importance of this molecule to plant health. Any fluctuations, increases or decreases, in cellular AsA levels can have profound effects on plant growth and development, as AsA is associated with the regulation of the cell cycle, redox signaling, enzyme function and defense gene expression. Although there has been significant progress made investigating the multiple roles AsA plays in stress tolerance, many aspects of AsA-mediated physiological responses require additional research if AsA metabolism is to be manipulated to enhance stress-tolerance. This book summarizes the roles of AsA that are directly or indirectly involved in the metabolic processes and physiological functions of plants. Key topics include AsA biosynthesis and metabolism, compartmentation and transport, AsA-mediated ROS detoxification, as well as AsA signaling functions in plant growth, development and responses to environmental stresses. The main objective of this volume is therefore to supply comprehensive and up-to-date information for students, scholars and scientists interested in or currently engaged in AsA research.

This volume brings together various theories of how aberrations in mitochondrial function and morphology contribute to neurodegeneration in idiopathic and familial forms of Parkinson’s disease. Moreover, it comprehensively reviews the current search for therapies, and proposes how molecules are involved in specific functions as attractive therapeutic targets. It is expected to facilitate critical thought and discussion about the fundamental aspects of neurodegeneration in Parkinson’s disease and foster the development of therapeutic strategies among researchers and graduate students. Theories of idiopathic Parkinson’s etiology support roles for chronic inflammation and exposure to heavy metals or pesticides. Interestingly, as this project proposes, a case can be made that abnormalities in mitochondrial morphology and function are at the core of each of these theories. In fact, the most common approach to the generation of animal and cell-culture models of idiopathic Parkinson’s disease involves exposure to mitochondrial toxins. Even more compelling is the fact that most familial patients harbor genetic mutations that cause disruptions in normal mitochondrial morphology and function. While there remains to be no effective treatment for Parkinson’s disease, efforts to postpone, prevent and “cure” onset mitochondrial aberrations and neurodegeneration associated with Parkinson’s disease in various models are encouraging. While only about ten percent of Parkinson’s patients inherit disease-causing mutations, discovering common mechanisms by which familial forms of Parkinson’s disease manifest will likely shed light on the pathophysiology of the more common idiopathic form and provide insight to the general process of neurodegeneration, thus revealing therapeutic targets that will become more and more accessible as technology improves.

The improved understanding of ion channel structure, achieved through the use of molecular biology techniques, has opened the way for the development of new drugs targeted at specific types of ion channels. This book provides a comprehensive, single-volume overview of the effects of different drugs and toxins on ionic channels. The first part of the book deals with the development of ion channels, while subsequent chapters detail the electrophysiological properties and pharmacology of eight different types of ion channels, including intracellular, cyclic nucleotide-gated, and receptor operated channels. Drug effects in various cell types, along with the potential use of channels in therapeutics, are discussed for each channel type. Comprehensive and up-to-date, Ion Channel Pharmacology is an essential reference for every investigator in this fast-growing area of research.

Much of the biology of oxidative stress and oxidative signalling centres on the generation and handling of hydrogen peroxide. The overall aim for this book would be to provide an insightful and useful forum to assist with the understanding of the relevance of hydrogen peroxide generation and how this is managed in human biology. The target audience would be those who currently have an interest in the generation of ROS, but who do not have expertise in chemistry, as well as those experts in the chemistry of oxidative stress, but without detailed understanding of the biologically relevant setting. We would aim to bridge the gap in understanding between chemistry and biology.
