This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.

This book is written to help and enable students in how to observe biological specimens in terms of viscosity, mass, elasticity and work producing elements. The observations are related to underlying chemical reactions by means of strain (fractional length change) sensitivity of the reactions, and a theory is developed how to connect these. Their mathematical derivation is complex when three or more states are involved, but a method is presented here to demonstrate how to simplify this complex problem. Basic mathematical solutions that are useful for this book, are presented (Fourier and Laplace transforms, differential equations, matrix operations) together with Fortran programs in the Appendix.

This book culminates with state-of-the art knowledge on hematopoietic development in human species and discussions of the most recent breakthroughs with relevance to both researchers and clinicians.

The immune system is not bound by a single tissue but is instead bestowed with the challenge of warding off invading pathogens throughout the body. Constant surveillance of the body requires that the immune system be highly mobile and able to purge pathogens from all tissues. Because each tissue presents its own unique architecture and milieu, it is necessary for the immune system to be as malleable as it is dynamic. For example, how the immune system handles a pathogen in the lung can differ significantly from a pathogen encountered in the gut.

Understanding immune complexity in diverse tissue environments is a challenge for researchers. However, advances in imaging have greatly improved our ability to probe the immune system. From snap-shots in time to 4D movies, imaging systems have been used to generate stunning visualizations of immune cells in action throughout the body. These visualizations are not only aesthetically pleasing but they have yielded great advances in our understanding of immune function. This volume provides a synopsis of major insights in immunology revealed using imaging approaches. "Seeing is truly believing," and this volume was assembled to recognize past accomplishments and to provide visions of what the future holds in store in this exciting field.

When we began to organize the workshop "Calcium and Cellular Metabolism: Transport and Regulation" the goal we had in mind was to put together the knowledge of 2 several specialists on Ca + homeostasis, with various examples of cellular metabolisms 2 2 (such as protein synthesis), regulated by Ca + ions. Regarding the homeostasis of Ca + ions, we invited Ernesto Carafoli to write the first chapter as a general state-of-the-art introductory review. On the other hand, the other chapters are the contribution of different specialists on membrane calcium transport mechanisms, aiming to reunite at least in part the wide field of calcium homeostasis. We roughly try to group chapters that share similar subjects. The first group of chapters (Chapters 2 to 6), are mainly related to calcium channels. Thus, Chapter 2 by Rodolfo Llimis et a . describes a new concept related to the dimen sions of the calcium action domain at the inner mouth of calcium channels in the squid gi ant synapse and its relationship to neurotransmitter release. Chapter 3 by Martin Morad et a . informs us about new ways of identifying and measuring, by confocal microscopy, in dividual sites where calcium release occurs in ventricular myocytes. In the same group Osvaldo Uchitel and Eleonora Katz classify and evaluate the variety of calcium channels at the neuromuscular junction, in Chapter 4. Chapter 5 by Gustavo Brum et a ."

The endocannabinoid system consists of cannabinoid receptors, their endogenous lipid ligands (endocannabinoids) and the enzymatic machinery for their synthesis and degradation. In the brain, endocannabinoids regulate ion channel activity and neurotransmitter release and thereby contribute to various aspects of brain function, including memory, reward and emotions. Their ability to modulate synaptic efficacy has a wide range of functional consequences and provides unique therapeutic possibilities. Unprecedented advances have been made in the understanding of the role of endocannabinoids in the regulation of the emotional brain over the past few years. However, a comprehensive book encompassing all these aspects is still lacking. The book will provide an overview of the role played by the endocannabinoid system in the regulation of emotional processes with particular emphasis on the modulation of memory and reward for emotionally arousing events and for the regulation of motivational aspects in cannabis use.

The year 2010 marks the centennial for the identification of histamine and the first glimpse of its many physiological functions. From these initial findings a rich tapestry of research has uncovered roles for histamine in almost every physiological process with new findings emerging every year. These diverse roles of histamine have made for fertile ground for the discovery of novel therapeutics, and these drugs have been so successful that the term "antihistamine" has entered the common lexicon. This volume is an attempt to give a snapshot in time as to the current understanding of the role of histamine in just one important therapeutic area-inflammation. The first three chapters provide some background context for the rest of the book starting out with a historical perspective by Figueroa and Shankley. Bongers et al provide an overview of the pharmacology of the four histamine receptors and the chapter by Hiroshi Ohtsu describes how histamine is synthesized as well as the insights derived from mice where this synthesis is disrupted. The next several chapters discuss disease areas where histamine is known to be involved. Chapter 4 by Thomas Taylor-Clark outlines the role of histamine in allergic rhinitis, an area were antihistamines are commonly used. This is also true for ocular allergy as discussed by Ohbayashi et al. Both of these chapters highlight aspects of these conditions that are still not well-controlled and suggest the utility of new antihistamines targeting other histamine receptors.

In 1979 Dr Sperelakis published the `Origin of the Cardiac Resting Potential' in the Handbook of Physiology of the Heart. Since that time, many investigators and teachers of membrane biophysics have used this article as a source of reference on the fundamental principles and equations describing the factors that establish the resting potential in excitable and non-excitable cells. Professor Sperelakis has expanded the scope of this article to provide the present book, creating a comprehensive work and an invaluable reference on the electrophysiological concepts underlying cellular excitability. There has long been a need for a text which precisely defines the assumptions underlying the derivations and equations that describe the principles of electrical excitability and maintenance of ion gradients in excitable cells. Here, Professor Sperelakis not only defines the equations and underlying concepts of membrane potentials, but gives working examples of solutions, thus allowing investigators to utilize the fundamental principles in their research, and students of membrane physiology to establish a sound basis of electrophysiological theory. `I have used the `Origin of the Cardiac Resting Potential' in graduate courses on cell physiology and biophysics, and look forward to using this new book. The time and effort required to put this work together reflects the dedication of Dr Sperelakis to the field of membrane biophysics and electrophysiology in his long, productive career.' From the Foreword by Dr David R. Harder.

Conceptually unsavoury, airway mucus is vital to homeostasis in the respiratory tract. In contrast, when abnormal, mucus contributes significantly to the pathophysiology of a number of severe bronchial diseases, including asthma, chronic bronchitis and cystic fibrosis. This volume provides wide ranging and in-depth coverage of the scientific and clinical aspects of airway mucus. It commences with introductory chapters which address the biochemical and molecular biological basis of airway mucus and continues with comprehensive coverage of the various physiological and rheological aspects of respiratory secretions. The clinical aspects of the topic are then considered, with chapters discussing the involvement of mucus secretions in bacterial infection and in hypersecretory diseases of the airway. The volume concludes with a discussion of the therapeutic aspects of the topic, both in terms of the possible approaches to the treatment of mucus hypersecretion and the interaction of these drugs with airway mucus. Written by leading experts in the field, each contribution provides a comprehensive review of its particular subject. Reflecting the latest advances in this important area of respiratory research, this volume will be of great interest to scientists and clinicians working in the field of airway secretions and related areas.

Food or calorie restriction has been shown in many short-lived animals and the rhesus monkey to prolong life-span. Life-long nutrition studies are not possible in humans because of their long survival. Studies over two to six years in healthy adult humans have, however, shown that a 20% reduction in food or calorie intake slows many indices of normal and disease-related aging. Thus, it is widely believed that long-term reduction in calorie or food intake will delay the onset of age-related diseases such as heart disease, diabetes and cancer, and so prolong life.

Over the last 20 or more years there has been a progressive rise in food intake in many countries of the world, accompanied by a rising incidence of obesity. Thus our increasing food and calorie intake has been linked to the rising incidence of cardiovascular disease and diabetes in early adult life. It is accepted that overeating, accompanied by reduced physical exercise, will lead to more age-related diseases and shortening of life-span. The answer is to reduce our calorie intake, improve our diet, and exercise more. But calorie restriction is extremely difficult to maintain for long periods. How then can we solve this problem?

Edited by a team of highly distinguished academics, this book provides the latest information on the beneficial effects of calorie restriction on health and life-span. This book brings us closer to an understanding at the molecular, cellular and whole organism level of the way forward.
