Considerable evidence exists that visual sensory information is analyzed simultaneously along two or more independent pathways. In the past two decades, researchers have extensively used the concept of parallel visual channels as a framework to direct their explorations of human vision. More recently, basic and clinical scientists have found such a dichotomy applicable to the way we organize our knowledge of visual development, higher order perception, and visual disorders, to name just a few. This volume attempts to provide a forum for gathering these different perspectives.
The over-arching goal of this volume is to help infertility practitioners evaluate and manage their patients with poor semen quality. The authors review the existing literature on the effects of medications on male fertility, and provide detailed information about what is known, giving the number of individuals and population characteristics for studies of medication effects on male fertility. Medications are designed to treat illness and reduce symptoms, but all have undesirable adverse effects such as headache or stomach upset. Some adverse reactions can even be life-threatening, so it is no surprise that some drugs have negative effects on male reproduction. Medical practitioners rarely consider a man's reproductive plans when prescribing medications. Men are routinely treated with drugs that can impair or abolish fertility. Although practitioners in the field of reproductive medicine generally realize that certain drugs impact negatively on reproductive health, there are limited resources providing evidence-based knowledge useful in counseling patients. Tables throughout this volume summarize the information for each drug, providing a handy reference for clinical use.
When we walk, drive a car, or fly an airplane, visual motion is
used to control and guide our movement. Optic flow describes the
characteristic pattern of visual motion that arises in these
situations. This book is the first to take an in-depth look at the
neuronal processing strategies that underlie the brain's ability to
analyze and use optic flow for the control of self-motion. It does
so in a variety of species which use optic flow in different
behavioral contexts. The spectrum ranges from flying insects to
birds, higher mammals and man. The contributions cover
physiological and behavioral studies as well as computational
models. Neuronal Processing of Optic Flow provides an authoritative
and comprehensive overview of the current state of research on this
topic written by a group of authors who have made essential
contributions to shaping this field of research over the last ten
years.
This book is an essential handbook on bisphosphonates, the most
widely used new class of drugs for osteoporosis therapy. It reviews
basic physiology in addition to the indications and adverse
reactions of these drugs. Bisphosphonates in Bone Disease, 4E,
discusses the compounds' chemistry, mechanisms of action, and
animal toxicology before presenting a clinical picture of the
diseases treated by bisphosphonates. The book provides a table
listing the trade names of the commercially available
bisphosphonates, registered indications, and the available forms
for various countries. The revised Fourth Edition contains
approximately 50% new material, including information on all of the
latest drugs.
Protein conversion from a water-soluble native conformation to the insoluble aggregates and fibrils, which can deposit in amyloid plaques, underlies more than 20 human diseases, representing a major public health problem and a scientific challenge. Such a conversion is called protein misfolding. Protein misfolding can also involve errors in the topology of the folded proteins and their assembly in lipid membranes. Lipids are found in nearly all amyloid deposits in vivo, and can critically influence protein misfolding in vitro and in vivo in many different ways. This book focuses on recent advances in our understanding of the role of lipids in modulating the misfolding of various proteins. The main emphasis is on the basic biophysical studies that address molecular basis of protein misfolding and amyloid formation, and the role of lipids in this complex process.
The study of inflammation has captured the interest of scholars since the earliest recorded history. Symbols identifying the cardinal signs of inflammation were uncovered in both Sanskrit and hieroglyphics (1). Since complete apprecia tion of the inflammatory process is underscored by the need for knowledge at both the cellular and molecular levels, academic inquiry in the area of inflammation has led, in many respects, the foray of current biomedical research. Molecular and Cellular Basis of Inflammation represents research from the cutting edge in the broad view of inflammation. The chapters are written by experts with a multidisciplinary approach to the study of inflammatory and cellular processes, and thus include contributions form the fields of molecular biology, biochemistry, pharmacology, immunology, and pathobiology. Molecular and Cellular Basis of Inflammation was first conceived during a mini symposium sponsored by the American Society for Investigative Pathology held at FASEB in 1995 entitled "The Role of Reactive Lipids, Oxygen and Nitro gen Metabolites in Inflammation," at which several of the contributing authors delivered lectures. This present, much-extended volume includes leading-front descriptions of both protein and lipid mediators. The chapter devoted to the comple ment cascade by Ward and colleagues, as well as Chapters 3-7 and 13, provide up to-date descriptions of the biosynthesis, molecular biology, chemistry, and actions of both protein and lipid mediators.
This comprehensive and definitive work succeeds and expands on the
highly successful HLA and Disease published in 1994. This new
edition has been updated, redesigned and reorganised into three
sections making it an invaluable reference.
microRNAs (miRNAs) are small non-coding RNAs that regulate various biological phenomena, such as development and homeostasis. The dysregulation of miRNA leads to disease progression, particularly of cancer. In Circulating MicroRNAs: Methods and Protocols, expert researchers in the field detail recent advances in the isolation, purification and analysis of circulating miRNAs from a variety of sources for research. The book is divided into three main topics. The first section involves the study of secretory miRNAs in cell-cell communication, and the second, the study of circulating miRNAs in body fluids. The last describes the novel techniques used to study circulating miRNAs. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Circulating MicroRNAs: Methods and Protocols seeks to aid scientists in dealing with the recent advances of RNAi technology from the bench to the bedside.
Oxidation is any reaction in which electrons are removed from a molecule, thus increasing the number of binding sites on the molecule that are able to react with other atoms and molecules.;This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Recent work in this area has revealed that these mechanisms may be linked with different disease processes, such as immune response, cell proliferation, inflammation, metabolism, ageing and cell death. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized.
How and to what extent have Islamic legal scholars and Middle Eastern lawmakers, as well as Middle Eastern Muslim physicians and patients, grappled with the complex bioethical, legal, and social issues that are raised in the process of attempting to conceive life in the face of infertility? This path-breaking volume explores the influence of Islamic attitudes on Assisted Reproductive Technologies (ARTs) and reveals the variations in both the Islamic jurisprudence and the cultural responses to ARTs.
Gert Ter Horst and a panel of recognized experts illuminate the complexities and importance of heart-brain and brain-heart interactions in human health. These distinguished authorities critically review what is known about autonomic control of the heart, hypothalamo-pituitary- adrenal modulation, heart pain, modulation by humoral factors, and the relationship between cognitive/neuropsychiatric disorders and heart disease. Highly relevant and up-to-date, The Nervous System and the Heart offers the first comprehensive treatment of the important mutual interactions of the heart and the brain. By integrating specialist knowledge in cardiology with that from neuroscience, this important book constitutes a brilliant guide to today's novel approaches to neural control of the heart and consequent reduction of cardiovascular mortality.
The present volume is the first in the advances in oncobiology series. It is meant to be useful not only to clinical and non-clinical oncologists but also to graduate students and medical students. The individual chapters are presented as self-contained summaries of current knowledge rather than as reviews. The last chapter deals with the subject of chemotherapy.
In this volume of Reviews of Physiology, Biochemistry and Pharmacology there a contributions by M.D. Swope, E. Lolis, F.Hofmann, L. Lacinova, N. Klugbauer, M. Hermann, P. Berger, S.S. Shen, J.S. Kim, M.E. Weksler, M. Hirsch-Kauffmann and M.Schweiger.
Anesthetics produce a reversible state of unconsciousness accompanied by ante- grade amnesia. This remarkable phenomenon brings great relief to surgical patients and wonder to clinicians and scientists. To date, we do not fully understand the mechanisms by which anesthetics ablate conscious sensation and memory. We are, however, making progress. This book presents original results as well as overviews of the current state of knowledge of the problem. It is authored by investigators who know the ?eld well; their research at a number of levels has contributed substantially to our c- rent understanding of anesthetic modulation of memory and consciousness. Most of the contributors were presenters at two workshops organized by Dr. Pearce and Dr. Hudetz at the 40th Annual Winter Conference on Brain Research, held at Snowmass Village, Colorado, from January 27 through February 2, 2007. One workshop focused on anesthetic modulation of consciousness and another on an- thetic modulation of memory. Seven of the chapters are based on material presented at these symposia - appropriately updated with new relevant ?ndings. This infor- tion is supplemented by chapters on anesthesia and sleep, computational analysis of the state of anesthesia, and the clinical phenomenon of "anesthesia awareness," a topic that has recently received much public attention. With these three additional contributions, the book thus includes 10 chapters.
The field of microRNA biology is really emerging in the last couple of years. Several investigators highlighted the importance of miRNAs in cancer. Although there is so much literature on microRNAs exist, a comprehensive book is still not available. Thus this book will be a great use to the scientists in the field of cancer biology. In addition, this book will be a good source of information for undergraduate, graduate students who want to develop their research careers in cancer biology.
In recent years, the advancing science and increasing availability of assisted reproduction have given new hope to infertile couples. However, the use of IVF and ART has also led to marked increases in the number of multiple-infant live births. This poses a public health concern, as these neonates have a higher rate of pre-term delivery, compromising their survival chances and increasing their risk of lifelong disability. By optimizing the selection of gametes and embryos with high probabilities of implantation, it is possible to reduce the number of embryos transferred and, by extension, the number of high-risk multiple gestations, while maintaining or increasing pregnancy rates. Human Gametes and Preimplantation Embryos: Assessment and Diagnosis provides a broad yet concise overview of established and developing methodologies for assessment of gamete and embryo viability in assisted reproduction. This book elucidates the best practices for precisely selecting viable specimens based on morphology and cleavage rate and covers the spectrum of emerging adjunctive technologies for predicting reproductive potential. The authors present their extensive knowledge of "omics" approaches (genomics, transcriptomics, proteomics, and metabolomics), with unbiased delineation of the associated advantages and potential pitfalls. This valuable clinical resource is well suited to infertility specialists, Ob/Gyn physicians, IVF laboratory technicians, and researchers in the fields of embryology and reproductive medicine.
The Aging Skeleton is a comprehensive and timely book on all
aspects of the skeleton as it ages, including basic mechanisms and
pathways as well as pathobiology. Chapters cover general aspects
and models of aging, determinants and maintenance of peak bone
mass, mechanisms of age-related bone loss, quantifiable
manifestations of age-related bone loss, fractures, and
therapeutics.
Well known experts in the field of Chronobiology from around the world, provide an integrative view of the state of the art of circadian biology. At present, genetic and epigenetic interaction of regulatory pathways among circadian oscillators, metabolic networks, cellular differentiation and neuronal communication are subject of intense scrutiny. The book is organized in three sections: The first includes selected examples of the circadian systems of crustaceans, insects, fish, birds and mammals. The second is a detailed view of the physiological mechanisms underlying the circadian clocks in mammals. Finally, in the third section some examples of the relevance of circadian biology and circadian misalignment to health and disease are provided including nutrition and metabolism, obesity, cancer, cardiovascular and pulmonary diseases, Huntington and affective diseases. This section concludes with a brief review on gene therapy and its potential use as a therapeutic tool to correct "clock genes" pathologies. This book is aimed at all those interested in contemporary aspects of physiology, biochemistry and molecular biology applied to the study and characterization of timing systems.. It could be used as an initial approach to this field, but it also provides updated information for those already familiar with the fascinating field of Chronobiology.
Stress is a double edged sword. Whereas chronic stress has well known harmful effects, recent research shows that intermittent exposure of cells and organisms to mild stress can improve various biological parameters, including severe stress tolerance, health span and longevity. Mild stress-induced hormesis is potentially a powerful tool in gerontological research and interventions. This book brings together some of the world leaders in this area of research who present a critical analysis of the ongoing research with respect to the effects and mechanisms of action of various types of mild stress, such as irradiation, heat, physical exercise, hypergravity, pro-oxidants and nutritional components, on a variety of biological systems ranging from fruitflies to human cells and bodies. Their separate chapters and a final collective chapter open up a whole new world of possibilities for future research in aging, successful aging, and health span extension.
Superantigen Protocols assembles experimental protocols that have proved useful for the study of superantigens. These techniques will allow researchers from various areas of cell biology, microbiology, immunology, biochemistry, and molecular biology to assess the physical characteristics and biological effects of well-known superantigens as well as of putative substances that might have superantigenic activities, and to explore therapies for superantig- induced effects. Microbial exotoxins have been studied for decades as virulence factors because of their pathogenic effects. The term "superantigen" was coined by Marrack and Kappler a decade ago for some of these molecules because of their potent T-cell stimulatory activities. In recent years, advances in mole- lar biology provide recombinant as well as natural superantigens in highly purified form for physical characterization. Superantigens are now used extensively as tools to study interactions between receptors on cells of the immune system as they bind to major histocompatibility complex class II m- ecules on antigen-presenting cells and V regions of T-cell receptors. The b- ? logical effects that result from these interactions are studied both in vitro and in vivo. The intent of this book is, therefore, to bring together up-to-date te- niques developed by experts in the field of biochemistry, immunology, and molecular biology for the study of superantigens. Superantigen Protocols begins with an overview of the field to provide background information on the various classes of superantigens and their str- ture.
This collection of contributions on the subject of the neural mechanisms of sensorimotor control resulted from a conference held in Cairns, Australia, September 3-6, 2001. While the three of us were attending the International Union of Physiological Sciences (IUPS) Congress in St Petersburg, Russia, in 1997, we discussed the implications of the next Congress being awarded to New Zealand. We agreed to organise a satellite to this congress in an area of mutual interest -the neuroscience of movement and sensation. Australia has a long-standing and enviable reputation in the field of neural mechanisms of sensorimotor control. Arguably this reached its peak with the award of a Nobel Prize to Sir John Eccles in 1963 for his work on synaptic transmission in the central nervous system. Since that time, the subject of neuroscience has progressed considerably. One advance is the exploitation of knowledge acquired from animal experiments to studies on conscious human subjects. In this development, Australians have achieved international prominence, particularly in the areas of kinaesthesia and movement control. This bias is evident in the choice of subject matter for the conference and, subsequently, this book. It was also decided to assign a whole section to muscle mechanics, a subject that is often left out altogether from conferences on motor control. Cairns is a lovely city and September is a good time to visit it.
This second edition volume discusses the revolutionary development of faster and less expensive DNA sequencing technologies from the past 10 years and focuses on general technologies that can be utilized by a wide array of plant biologists to address specific questions in their favorite model systems. This book is organized into five parts. Part I examines the tools and methods required for identifying epigenetic and conformational changes at the whole-genome level. Part II presents approaches used to determine key aspects of a gene's function, such as techniques used to identify and characterize gene regulatory networks. This is followed by a discussion of tools used to analyze the levels of mRNA, mRNA translation rates and metabolites. Part III features a compilation of forward and reverse genetic approaches that include recent implementation of high-throughput sequencing in classical methodologies such as QTL mapping. The final two parts explore strategies to facilitate and accelerate the generation and testing of functional DNA elements and basic computational tools used to facilitate the use of systems biology approached by a broad spectrum of plant researchers. Written in the highly successful Methods of Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols and key tips on troubleshooting and avoiding known pitfalls. Practical and timely, Plant Functional Genomics: Methods and Protocols, Second Edition highlights the latest developments in DNA sequencing technologies that are likely to continue shaping the future of functional genomics.

Nearly, 50 years ago, Karl Pribram in a discussion section accompanying MacLean's proposal of a limbic system, criticized the visceral or limbic brain concept as theoretically too vague and cumbersome. In a recent review of the limbic system, Swanson points to Brodal's criticism that the discovery of connections of limbic structures with virtually all parts of the nervous system render the concept of the limbic system useless, and better abandoned. Additional dissatisfaction surrounding the limbic brain concept stems from the feeling that it is historically inert (an antiquated 19th century construct). In our current age of neural networks, and parallel distributed process it is of little value, merely an historical curio. So why then this int- duction to limbic brain anatomy? We offer several interrelated rationales behind our labors. Recapitulation in the Service of Education: Although concepts had evolved in the second half of this century which effectively overthrew the idea of relatively isolated hemispheric districts (i. e. striatal, cortical, and limbic), parsing the hemisphere into these three districts was an important preliminary step achieved by our forebears in their efforts to understand the large scale structure of the higher mammalian cerebral hemisphere. An examination of how the limbic brain concept came to be provides an opp- tunity to recapitulate the process of exploration, discovery, and und- standing as it relates to one of these principle hemispheric domains. |
