Since Paul Cranefield published his monograph, The Conduction of the Cardiac Impulse, in 1975, much has been learned about the role of the slow inward current in cardiac electrophysiology. Because of this expanse in know ledge, both basic and clinical, it appeared reasonable to review in a mono graph once again what was known. When Martinus Nijhoff first approached us to undertake the task of updating this information, we were initially reluctant for several reasons. First, we did not feel that the subject could be adequately and thoroughly reviewed, from the cell to the bedside, by a single person. Second, time constraints on all of us precluded even attempting such a task. However, we were encouraged by several of our friends (' egged on' one might even say, since they wished the job done but did not want to do it themselves ) who promised faithfully to contribute chapters on time if we accepted the task. So we did, and most of them did also."
This book examines how post-transcriptional mechanisms control endocrine function. This includes newly identified regulatory mechanisms involved in hormone biosynthesis, control of hormone receptors and the outputs of hormone mediated signal transduction. Chapters address endocrine hormones including protein peptide/peptide, steroid, and non-steroidal hormones. The impacts of these mechanisms on disease and health are covered, providing a novel update to the scientific literature. Post-transcriptional regulatory mechanisms play an essential role in controlling dynamic gene expression. The outcome of this regulation includes control of the amount, timing, and location of protein expression. Regulation is mediated by cis-acting RNA sequences and structures and transacting RNA binding proteins and non-coding RNAs, including microRNAs. Recent advances in characterization of these regulatory factors have revealed enormous regulatory potential.
Enthusiasm from the past notable successes with RF ablation and the demand for better therapy for the complex but common arrhythmias has carried forward the progress of catheter ablation technology. In the past few years, there has been significant progress in the development of better mapping and ablative techniques. Such progress has resulted in a steady improvement in the success of ablation of more complex atrial and ventricular tachyarrhythmias as well as our knowledge of their anatomy and pathophysiology. However, enthusiasm for finding the ideal tools for the cure of complex arrhythmias has also resulted in a proliferation of changes in catheter designs, mapping apparatus, and heat energy sources. The clinician nowadays is faced with a wide and often confusing choice of new instruments and methods of ablation. There are few, if any, comparative studies involving the various new tools, nor is there any compilation of data on any specific new discovery. It is timely to provide ourselves with a review of available data on the progress of new technology in order to enhance our knowledge and to concentrate our efforts into the development of an ultimate practical and yet effective methodology. The purpose of this publication is to provide a forum in which the authors can present their experience, even if only in its preliminary stages, in the respective field or technology. Various technological advancements in mapping and ablation as well as the improved understanding of the pathophysiology of the various arrhythmias are presented. The authors are selected for their interest and expertise on the subject. Each topic is presented in a concise form and with relevance to thedevelopment of new technology. The authors are encouraged to provide their opinion on the issues to stimulate further discussion and investigation. We hope that this publication will also stimulate further growth in this exciting field of cardiac electrophysiology.
This leading-edge volume offers a new framework for neuropsychological testing rooted in the current evidence base on large-scale brain system interactions. Expert coverage brings traditional discrete areas of cognitive functioning (e.g., attention, memory) in line with highly nuanced relationships between cortical and subcortical processing. The new findings point to more accurate and targeted testing, as authors expand on the judicious addition of nonstandardized methods to core diagnostic tools and the underused capacity of neuropsychological testing to assess social behavior and personality. The book's emphasis on cognition in context gives practitioners better understanding of assessment and evaluation, leading to improved diagnosis, treatment, and outcomes for individuals as well as significant improvements in the field. This innovative reference: Reframes cognitive functioning in light of current data on brain interconnectivity. Critiques current methods of neuropsychological test interpretation. Reviews known, useful interpretive methodologies within a new context. Features instructive case examples emphasizing accurate historical and test data. Revisits the strengths and limitations of the bell curve construct. Examines the interpretive significance of pathognomonic signs. Details strategies for making neuropsychological evaluations more clinically relevant. Large-Scale Brain Systems and Neuropsychological Testing combines current findings, clinical sense, and common sense to ground neuropsychologists, school psychologists, child psychologists, and clinical social workers in the effective assessment of real-world functioning.

In addition to its central role in blood coagulation, it has become increasingly apparent that thrombin and thrombin receptors are involved in many other physiological processes and can contribute to a variety of disease states such as tumor progression and metastasis, inflammation, neurological disorders and cardiovascular complications. This book is a collection of reviews of up-to-date information on the above topics by leaders in these fields. This book will be of value to researchers and academic professionals both in basic and clinical science who are interested in the fields of biochemistry, biophysics, cell biology, pharmacology, cancer, inflammation, angiogenesis, cardiovascular system and neuronal system. These areas of research are prime target areas for drug development by many pharmaceutical and biotechnology companies.
Physiological, pharmacological and molecular biological data generated over the past three decades have demonstrated the existence of two major families of extracellular receptors, the P1, a family of four G-protein coupled receptors and the P2, a family of at least 12 receptors responsive to purine (ATP, ADP) and pyrimidine (UTP) nucleotides through which adenosine and ATP can function as extracellular messengers. The present two-part volume represents an integrated compendium of invited chapters by leading researchers in the area focusing on advances in the understanding of purinergic and pyrimidinergic signaling systems, their role(s) in tissue function and pathophysiology and advances in developing potential new medications based on the modulation of P1 and P2 receptor signaling processes. The volumes will thus provide the reader with a topical, comprehensive and integrated overview of this important area.
Systemic lupus erythematosus (SLE), commonly called lupus, is a chronic autoimmune disorder that can affect virtually any organ of the body. In lupus, the body's immune system, which normally functions to protect against foreign invaders, becomes hyperactive, forming antibodies that attack normal tissues and organs, including the skin, joints, kidneys, brain, heart, lungs, and blood. Lupus is characterized by periods of illness, called flares, and periods of wellness or remission. Because its symptoms come and go and mimic those of other diseases, lupus is difficult to diagnose. There is no single laboratory test that can definitively prove that a person has the complex illness. To date, lupus has no known cause or cure. Early detection and treatment are the key to a better health outcome and can usually lessen the progression and severity of the disease. Anti-inflammatory drugs, antimalarials, and steroids (such as cortisone and others) are often used to treat lupus. Cytotoxic chemotherapies, like those used in the treatment of cancer, are also used to suppress the immune system in lupus patients. A new edition of this established and well-regarded reference combines basic science with clinical science to provide a translational medicine model. Systemic Lupus Erythematosus, Sixth Edition, is a useful reference for specialists in the diagnosis and management of patients with SLE, a tool for measurement of clinical activity for pharmaceutical development and basic research of the disease, and a reference work for hospital libraries.

In Heart Cell Communication in Health and Disease an extensive review of different aspects of heart cell communication is presented. The book starts with the fundamental concept that cardiac cells are communicated, and then proceeds to the role of gap junctions in heart development, the molecular biology of gap junctions, the biophysics of the intercellular channels, the control of junctional conductance and the influence of gap junctions on impulse propagation. This is the first time that a single volume has described cell communication in the normal heart and under different pathological conditions such as heart failure, coronary disease, myocardial ischemia and cardiac arrhythmias. In this way the process of cell communication is analyzed at different levels of complexity, providing the reader with a wide view of this field and its relevance to cardiology.
It is remarkable how much we take for granted the tremendous energy and vitality that the sun provides earth's inhabitants. As we enter the new millennium, it is worthwhile to review how our ancestors perceived the biologic effects of sunlight, and how science and medicine have advanced our knowledge about the biologic effects of light. At the turn of the century, a multitude of investigators explored the use of sunlight and artificial radiation for treating a multitude of diseases. These explorations gave rise to photodynamic therapy, phototherapy, and chemophototherapy. However, enthusiasm for using sunlight and artificial radiation to treat disease was dampened with the birth of pharmacology. It was the goal of the Fifth International Arnold Rikli Symposium on the Biologic Effects of Light, held in Basel, Switzerland, on November 1-3, 1998, to review the history of phototherapy and have some of the world's leading experts on the biologic effects of light provide new perspectives on the positive and negative effects of light. The general topics included a broad range of biologic effects of sunlight, artificial ultraviolet radiation and electromagnetic radiation. Special sessions on radiation and vitamin D and bone health, photoimmunology, biopositive effects of UV radiation, effects of electromagnetic currents and fields, and ocular and non-ocular regulation of circadian rhythms and melatonin, should be of particular interest to readers of Biologic Effects of Light.
Over the years there has been growing interest among the scientific community in investigating sleep and how it affects the memory and other brain functions. It is now well established that sleep helps in memory consolidation and induction of neural plasticity, and that short-term deprivation of either total sleep or rapid eye movement sleep alone can induce memory deficits very quickly. Quantitative and qualitative changes in sleep architecture after different training tasks further suggest that discrete memory types may require specific sleep stage/s for optimal memory consolidation, and studies indicate that sleep deprivation alters synaptic plasticity and membrane excitability in the hippocampal neurons and synaptic up-scaling in the cortical neurons. Further, sleep alteration during pregnancy may increase the risk of depression and adversely affect maternal-child relationships, parenting practices, family functioning, and children's development and general wellbeing. This book coherently discusses all these aspects, with a particular focus on the possible role of sleep in memory consolidation and synaptic plasticity. It also highlights the detrimental effects of sleep loss on mental health, the immune system and cognition. This book is a valuable reference resource for students and researchers working in the area of sleep, memory, or neuronal plasticity.
The Sixth International Meeting on Cholinesterases and Related Proteins, Choli nesterases '98, was organized by Palmer Taylor and his associates at the University of California-San Diego and convened in La Jolla, California, USA, in March of 1998. This was the first conference of the series to be held in the United States, let alone on the Pa cific Rim. Nearly 200 delegates from twenty countries-from Asia, Australia, Europe, and North and South America-heard 75 oral presentations and viewed 90 posters on current research on cholinesterases and related proteins. The meeting framework was structured to include two days of plenary sessions, followed by two days of concurrent sessions and workshops in specific areas. Communication at the concurrent sessions was facilitated by the conference settings of the Martin Johnson House, on a scenic bluff overlooking the blue Pacific Ocean, and the San Diego Supercomputer Center, which enabled projection and rotation of protein structures in three dimensions for a large audience. This book is the compilation of the presentations at the Sixth International Meeting on Cholinesterases and Related Proteins into a volume that describes recent investigations on the structure, catalytic and non-catalytic functions of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and related proteins, as well as studies on the molecular and cellular biology of these enzymes and the genes that encode them."

The forty-seven chapters offer a review of current topics and ongoing research in paediatric sport and exercise science and medicine. The book is therefore a key text for all researchers, lecturers, paediatricians, health professionals and students with an interest in the exercising child in health and disease.
Information flow as nerve impulses in neuronal circuits is regulated at synapses. The synapse is therefore a key element for information processing in the brain. Much attention has been given to fast synaptic transmission, which predominantly regulates impulse-to-impulse transmission. Slow synaptic transmission and modu lation, however, sometimes have been neglected in considering and attempting to understand brain function. Slow synaptic potentials and modulation occur with a considerable delay in response to the accumulation of synaptic and modulatory inputs. In these contexts, they are plastic in nature and play important roles in information processing in the brain. A symposium titled "Slow Synaptic Responses and Modulation" was held as the satellite symposium to the 75th Annual Meeting of the Physiological Society of Japan on March 30-31, 1998, in Kanazawa. The theme was selected not only for the reason mentioned above, but also because of the considerable involvement of many Japanese scholars in establishing the basic issues. Following the dawn of synaptic physiological research, as Sir John Eccles, Sir Bernard Katz, and Professor Stephen Kuffler carried out pioneer work, Professor Kyozou Koketsu and Professor Benjamin Libet, the students of Sir John Eccles, and their colleagues established the concept of slow synaptic responses and modulation by studying vertebrate sympathetic ganglia. Since then, the concept has been ex panded with detailed investigations of both peripheral and central synapses at the levels of single ion channels, intracellular Ca"+ dynamics, intracellular transduc tion mechanisms, and genes.
Mitochondria from mammalian tissues possess an elaborate system for 2+ 2+ transporting Ca across their inner membrane which consists of Ca import, 2+ via the Ca uniporter, in response to the mitochondrial membrane 2+ + potential ?? and of Ca release by an antiport system in exchange for H + 9,23 or Na (see Fig. l) . Because the uniporter is dependent upon the external 2+ 2+ 2+ 2+ Ca concentration ([Ca ]), mitochondria accumulate Ca until the [Ca ] o o 2+ decreases to the level at which the uniporter activity balances the Ca efflux. 2+ The [Ca ] at which the uniporter and efflux activities are equal is defined o the "setpoint" andcorresponds to values between 0.3-3M. 2+ Figure 1.
