Autotrophic and methylotrophic microorganisms are able to grow at the expense of one-carbon compounds (e.g. carbon dioxide, formaldehyde) as the principal carbon sources for the synthesis of cell material, using light, inorganic compounds or one-carbon compounds as energy sources. The study of the special adaptations required in aerobic and anaerobic microorganisms to sustain an autotrophic or methylotrophic mode of life is a fascinating field of research for scientists from various disciplines. Current research efforts not only focus on fundamental aspects, i.e. metabolic pathways and their regulation, ecology, energy conversion and genetics, but also the possible application of these organisms, in waste water treatment, degradation of xenobiotics, single-cell protein production, as biocatalysts for the production of fine chemicals, draws strong attention. The aim of this series is to provide annual reviews on the biochemistry, physiology, ecology, genetics, and application of microbial autotrophs and methylotrophs. The scope of the series includes all aspects of the biology of these microbes, and will deal with phototrophic and chemolithotrophic prokaryotic autotrophs, carboxydobacteria, acetogenic-, methanogenic- and methylotrophic bacteria, as well as methylotrophic eukaryotes. The exciting advances made in recent years in the study of these organisms is reflected in the chapters of this first volume which have been written by experts in the field. We would like to express our sincere thanks to all the contributors for their stimulating and comprehensive chapters.

Unraveling the functional properties of structural elements in the brain is one of the fundamental goals of neuroscientific research. In the cerebral cortex this is no mean feat, since cortical areas are defined microstructurally in post-mortem brains but functionally in living brains with electrophysiological or neuroimaging techniques - and cortical areas vary in their topographical properties across individual brains. Being able to map both microstructure and function in the same brains noninvasively in vivo would represent a huge leap forward. In recent years, high-field magnetic resonance imaging (MRI) technologies with spatial resolution below 0.5 mm have set the stage for this by detecting structural differences within the human cerebral cortex, beyond the Stria of Gennari. This provides the basis for an in vivo microanatomical brain map, with the enormous potential to make direct correlations between microstructure and function in living human brains. This book starts with Brodmann's post-mortem map published in the early 20th century, moves on to the almost forgotten microstructural maps of von Economo and Koskinas and the Vogt-Vogt school, sheds some light on more recent approaches that aim at mapping cortical areas noninvasively in living human brains, and culminates with the concept of "in vivo Brodmann mapping" using high-field MRI, which was introduced in the early 21st century.
Cardiorespiratory function is prominently affected by oxidative stress. Cigarette smoking is the archetype of oxidative and nitrative stress and free radical formation. New adverse effects of smoking keep on propping up in research. The chapters provide the comprehensive view of new developments in this area regarding cardiovascular and lung function and muscle catabolism. Alterations in inflammatory cytokines and proteins as well as degradation of muscle proteins due to smoking, by far unrecognized, caused by oxidative stress also are presented. Much less is known about the effect of cognitive stress on vagally-mediated cardiorespiratory function and surprisingly, on vagal immune pathway. The experimental studies also show that clinically important meconium aspiration syndrome contains an oxidative trait which is amenable to antioxidative treatment. This volume creates a source of information on the damaging role of oxidative stress in cardiorespiratory function that has by far not been available.
This book reviews current understanding of normal muscle tone and how it differs in spastic, thixotropic and hypotonic patients. The book contains practical advice on measuring the postural system and will be of interest to paediatricians and also to physiologists involved in investigating muscle tone.
Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Short chain fatty acids (SFCA) are synthesized by the colonic microflora primarily from non-absorbed carbohydrate; there is also some limited production from non-absorbed protein. In contrast, SFCA are not normally present in the diet. During the past 15 years SFCA have attracted considerable interest in human nutrition, physiology and pathophysiology as a result of the realization that SFCA represent an important mechanism for carbohydrate and calorie conservation and may play a role in various types of colitides and possibly in colonic neoplasia. In addition, SFCA, produced in large amounts by ruminants and other herbivores, have long been the province of veterinary physiologists. This book is based upon the presentations at the 73rd Falk Symposium held in Strasbourg, France, September 8--10, 1993, which brought together researchers and clinicians from five continents. It provides an excellent statement of the present state-of-the-art knowledge of SFCA.
In vertebrates, the integrin family includes 24 members. As the
alpha-chains were sequenced, some were observed to have an inserted
domain similar to the A domain in several matrix and complement
proteins. This inserted ligand binding domain is interactive and
was called the I domain in integrins. More recently structural data
have shown that an integrin beta-chain also contains an I domain.
Nine of the currently known 18 alpha-chains contain an I domain.
With the invention of compressed air in the 1840s, human divers could enter previously inaccessible deep water environments and engineers could design underwater mines and monumental bridges that had never been possible before. But a painful, sometimes fatal illness -- decompression sickness, or the bends -- mysteriously afflicted many of those who used compressed air. This book is a wide-ranging history of the wonders compressed air brought about and the suffering its unknown hazards inflicted. John L. Phillips explores the intertwining roles of science, technology, engineering, medicine, and politics in the invention of compressed air, the recognition and identification of decompression sickness, and the hundred-yearlong process of learning to understand and treat the bends. The book begins with an overview of the biology and chemistry of respiration and a discussion of the steam engine that could generate compressed air. Drawing on previously unpublished letters, diaries, and notes, Phillips tells the story of early uses of compressed air, first observations of decompression sickness, growing awareness of the bends during construction of the Brooklyn Bridge, and efforts to understand the pathophysiology of the illness. He then considers employee health and safety issues, the science of diving today, and human limits to exploring the ocean deeps. In the history of compressed air and its illnesses, Phillips finds important lessons for dealing with other diseases yet to be confronted in the modern world. "Phillips takes an interesting socio-scientific approach in this readable book. He tells the fascinating story of decompression sickness well". -- Peter B. Bennett, Divers AlertNetwork
This book describes the major steps by which the mammalian ear transforms sound into nerve impulses. The author leads us along the pathway followed by an acoustic signal--collected by the outer ear, augmented by the middle ear, then delivered to the inner ear where the minuscule vibrations of the sound waves are transformed into nerve impulses. At each stage, the basic mechanisms are described qualitatively in terms of current theories and illustrated with experimental data. Where appropriate, related mechanisms in the ears of other vertebrates are considered. It is shown that the mammalian ear does an exquisite job of translating sound signals into a very robust nerve-pulse code. The book concludes with descriptions of some common ear impairments and a brief survey of the treatments available for them. The text is integrated with animations of mechanical and neural phenomena available through the Internet.

This textbook presents concise chapters written by internationally respected experts on various important aspects of cancer-associated metabolism, offering a comprehensive overview of the central features of this exciting research field. The discovery that tumor cells display characteristic alterations of metabolic pathways has significantly changed our understanding of cancer: while the first description of tumor-specific changes in cellular energetics was published more than 90 years ago, the causal significance of this observation for the pathogenesis of cancer was only discovered in the post-genome era. The first 10 years of the twenty-first century were characterized by rapid advances in our grasp of the functional role of cancer-specific metabolism as well as the underlying molecular pathways. Various unanticipated interrelations between metabolic alterations and cancer-driving pathways were identified and currently await translation into diagnostic and therapeutic applications. Yet the speed, quantity, and complexity of these new discoveries make it difficult for researchers to keep up to date with the latest developments, an issue this book helps to remedy.
GABA (gamma-aminobutyric acid) is the main neurotransmitter regulating sleep. The majority of drugs presently in use for the treatment of sleep disorders act by enhancing GABAergic neuronal inhibition. The GABA system is, therefore, of prime clinical relevance for the therapy of insomnia. The focus of this volume is on the neuropsychopharmacology and the clinical impact of the GABA system in regulating sleep and wakefulness. It presents molecular, neuropharmacological, systems-biological and clinical approaches to the understanding of the mechanism of action of GABA and GABAergic drugs. It also explores the role of GABA in the basic drives that affect sleep, and the influences that adapt sleep and wakefulness to external events.
