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.
This is the second volume in a series on membrane protein transfer. Membrane protein transport underlies the topological disposition of many proteins within cells and it is this disposition that allows for the co-ordination of the central cellular processes, such as metabolism.
Given the at times confusing new information concerning the human microbiome released over the last few years, this book seeks to put the research field into perspective for non-specialists. Addressing a timely topic, it breaks down recent research developments in a way that everyone with a scientific background can understand. The book discusses why microorganisms are vital to our lives and how our nutrition influences the interaction with our own gut bacteria. In turn, it goes into more detail on how microbial communities are organised and why they are able to survive in the unique environment of our intestines. Readers will also learn about how their personal microbial profile is as unique as their fingerprint, and how it can be affected by a healthy or unhealthy lifestyle. Thanks to the open and easy-to-follow language used, the book offers an overview for all readers with a basic understanding of biology, and sheds new light on this fascinating and important part of our bodies.
Discusses the elements of the human body. Includes suggestions for related experiments and projects.
This book covers in detail the mechanisms for how energy is managed in the human body. The basic principles that elucidate the reactivity and physical interactions of matter are addressed and quantified with simple approaches. Three-dimensional representations of molecules are presented throughout the book so molecules can be viewed as unique entities in their shape and function. The book is focused on the molecular mechanisms of cellular processes in the context of human physiological situations such as fasting, feeding and physical exercise, in which metabolic regulation is highlighted. Furthermore the book uses key historical experiments that opened up new concepts in biochemistry to further illustrate how the human body functions at molecular level, helping students to appreciate how scientific knowledge emerges. New to this edition: - 30 challenging practical case studies (2-3 at the end of each chapter) based on movies, novels, biographies, documentaries, paintings, and other cultural and artistic creations far beyond canonic academic exercises. - A set of challenging questions and problems in the end of each case study to further engage students with the applications of medical biochemistry - Insights into the answers to the challenging questions to help steer teaching/learning interactions key to productive lectures, PBL (problem-based learning) or traditional tutorials, or e-learning approaches. Advance praise for the second edition: "The Challenging Cases are compelling both from a scientific viewpoint and for the perspective they provide on the history of medicine." David M. Jameson, University of Hawaii "Using case studies to reinforce the biochemistry lessons is extremely effective - as well as entertaining!" Joseph P. Albanesi, UT Southwestern Medical Center Advance Praise for the first edition: "This textbook provides a modern and integrative perspective of human biochemistry and will be a faithful companion to health science students following curricula in which this discipline is addressed. This textbook will be a most useful tool for the teaching community." Joan Guinovart Former director of the Institute for Research in Biomedicine, Barcelona, Spain, and former president of the International Union of Biochemistry and Molecular Biology, IUBMB
This book is an attempt to indicate to researchers and clinicians a simple way to approach the complexity of cardiovascular neural regulation. A conceptual pillar like homeostasis is contrasted with instability and a continuous interaction of opposing mechanisms that have negative and positive feedback characteristics, and is considered to subserve the multitude of patterns pertaining to physiology. However, in pathophysiological conditions the final design is most often replaced by largely purposeless neural mechanisms. The complexity of cardiovascular neural regulation, reflected by the state of sympathovagal balance, is also assessed in the frequency domain. Power spectrum analysis of heart rate and arterial pressure variability, a sophisticated but simply explained approach, provides an unprecedented tool to evaluate this interaction in both physiological and pathophysiological conditions. The elementary characteristics of nonlinear dynamics are also outlined. Finally, the need for an ethical structure for science and medicine is analyzed.
I wrote this book urged by the overwhelming desire that arises towards the end of life to recapitulate the past. My goal was to summarize my experience of practicing science at the end of the 20th and early 21st centuries in Argentina, a country located far away from the world's leading scientific centers. In the book, I summarize the intricacies of the pineal gland ("the stone of madness") as historical, mystical and medical entity and its entry in contemporary medicine with the description of melatonin. I also reflect on how being associated with an unexplored subject at the beginning of his scientific career impacts the life of a scientist throughout their entire life. Today we know that in humans pineal melatonin is released every day late in the evening, and there is evidence that it is the trigger for the sleep process. But the most exciting aspect of melatonin is that it is a substance that is present in all living creatures, from unicellular organisms to plants and higher mammals, a fact that evinces its importance for life. Further, the neuroprotective action of melatonin promises to be crucial for the control of neurodegenerative diseases we face as a pandemic in this century. The discoverer of melatonin, Aaron Lerner, based its name on melano, the Greek word for black, because of its effect on the pigment cells of the skin. As in "La vie en rose", the immortal Edith Piaf song written in 1946, my lifelong work with melatonin could well be called "Ma vie en noir".
This book provides a clearly structured introduction to hydrogen biology and medicine. Hydrogen is the one of the most abundant elements in the universe and has the simplest structure. In 2007, Japanese researchers found that the selective oxidation of hydrogen has a therapeutic effect on various diseases and injuries, sparking widespread interest in the biomedical field. In recent years, hundreds of peer-reviewed papers have been published internationally reporting the positive effects of hydrogen on many human diseases, including strokes, diabetes, Parkinson's disease, Alzheimer's disease and sepsis. The authors provide readers with a comprehensive overview of this subject, from its physical and chemical properties to its biological effects, as well as the problems and obstacles that exist.

This question-based learning text aims to provoke thinking and it should make learning physiology both enjoyable and challenging.
The central nervous system, which includes the brain and spinal cord, has a high metabolic demand. The physiology of the brain is such that it is easily affected by alterations in other systems, which in turn can compromise cerebral blood flow and oxygenation. Together the brain and spinal cord control the automatic function of our body systems. While other systems of body controls individual functions, central nervous system at the same time does many different functions, especially, controlling the function of other systems. This interaction between the brain and other systems is important when it comes to understanding how injuries to the brain can, at times, produce complications in remote organs or systems of the body, such as the lungs. This book explains the lesser-known crosstalks between acutely or chronically affected brain and lung, describing the pathophysiology of the lung following brain injury and discussing in detail the conflicts between the brain and lungs in relation to the tidal volumes, positive end-expiratory pressures, arterial carbon dioxide and oxygen levels, recruitment maneuvers and positioning, as well as potential therapeutic targets.

The cyclic purine nucleotides 3',5'-cAMP and 3',5'-cGMP are well-established second messengers. cGMP has recently been covered in a volume of the Handbook of Experimental Pharmacology (volume 191). In addition to 3',5'-cAMP and 3',5'-cGMP, so-called non-canonical cyclic nucleotides exist. These comprise the cyclic pyrimidine nucleotides 3',5'-cCMP and 3',5'-cUMP, the purine nucleotide 3',5'-cIMP, the 2',3'-nucleoside monophosphates and cyclic dinucleotides. In this volume of the Handbook of Pharmacology, word-leading experts in the field summarize our current knowledge on these non-canonical cyclic nucleotides, discuss open questions, future research directions and the pharmacotherapeutic implications. Special emphasis will be given to the emerging roles of 3',5'-cCMP and 3',5'-cUMP as second messengers with regard to generators, effectors, biological functions, inactivation and bacterial toxins. The role of 3',5'-cIMP as potential second messenger will also be critically discussed. Furthermore, we will consider transport of cyclic nucleotides and their potential role as first messengers. The role of the cyclic dinucleotide cGAMP in the immune system will covered, too. Lastly, the book will present important methodological aspects ranging from mass-spectrometric methods for cyclic nucleotide detection to the synthesis of nucleotide analogs as experimental tools and holistic methods for analysis of cyclic nucleotide effects.

This book examines the new knowledge that has been gained from the objective monitoring of habitual physical activity by means of pedometers and accelerometers. It reviews current advances in the technology of activity monitoring and details advantages of objective monitors relative to physical activity questionnaires. It points to continuing gaps in knowledge, and explores the potential for further advances in the design of objective monitoring devices. Epidemiologists have studied relationships between questionnaire assessments of habitual physical activity and various medical conditions for some seventy years. In general, they have observed positive associations between regular exercise and good health, but because of inherent limitations in the reliability and accuracy of physical activity questionnaires, optimal exercise recommendations for the prevention and treatment of disease have remained unclear. Inexpensive pedometers and accelerometers now offer the epidemiologist the potential to collect relatively precisely graded and objective information on the volume, intensity and patterns of effort that people are undertaking, to relate this data to past and future health experience, and to establish dose/response relationships between physical activity and the various components of health. Such information is important both in assessing the causal nature of the observed associations and in establishing evidence-based recommendations concerning the minimal levels of daily physical activity needed to maintain good health.
In a normal physiological state, several bacteria are present in the human gut that is essential to maintain the normal to healthy gastrointestinal function. Disturbances in this "normal flora" lead to gut inflammation and infection. This volume explores the potential of probiotics, the healthy bacteria, to manage gut-related diseases including gastrointestinal cancers, ulcerative colitis, H. pylori infections, and diarrhea; vaginosis; oral health; airway inflammation; and atopic dermatitis. The concept of designer probiotics, edible vaccines and future scope of research in the field is also presented. The animal models used for studying the benefits of probiotics in gut inflammation are described for beginners.
This book presents the current concepts of semaphorin biology. In the early 1990s, semaphorins were originally identified as axon guidance cues that function during neuronal development. However, cumulative findings have clarified that they have diverse functions in many physiological processes, including cardiogenesis, angiogenesis, vasculogenesis, osteoclastogenesis, retinal homeostasis, and immune regulation. Additionally, they have been implicated in the pathogenesis of various human diseases, including tumorigenesis/tumor metastasis, neuroregenerative diseases, retinal degeneration, irregular pulse/sudden death, and immune disorders. Based on this current research background, the book covers the essential state-of-the-art findings for basic scientists in biochemistry, molecular biology, neuroscience, developmental biology, and structural biology, as well as for physicians in neurology, cardiology, oncology, orthopedic surgery, otorhinolaryngology, ophthalmology, allergology, and rheumatology.

This is the first book to assemble the leading researchers in the field of LRRK2 biology and neurology and provide a snapshot of the current state of knowledge, encompassing all major aspects of its function and dysfunction. The contributors are experts in cell biology and physiology, neurobiology, and medicinal chemistry, bringing a multidisciplinary perspective on the gene and its role in disease. The book covers the identification of LRRK2 as a major contributor to the pathogenesis of Parkinson's Disease. It also discusses the current state of the field after a decade of research, putative normal physiological roles of LRRK2, and the various pathways that have been identified in the search for the mechanism(s) of its induction of neurodegeneration.
The concept of immunotherapy was in infancy when the first edition was written; since then, major advances have been made, not only with several prominent clinical trials, but also with the approval of cell-based therapy by the FDA for the treatment of cancer in 2010. These events resulted in a gradually narrowing gap between early scientific knowledge and the late development of immune-based therapies. Consequently, the significance and magnitude of these advances warranted a revision of this contribution; this revised edition will provide a deeper understanding of the recent advances and discoveries related to the function of the immune response and their applications in the development of novel therapies to treat human diseases. Some of the key discoveries during the past five years include: the identification of the new subsets of helper T cells; new cytokines and their networks; and novel signal transduction mechanisms. For example, the identification of TH17 subset of helper T cells, in addition to TH1 and TH2 cells, not only advanced our understanding of the function of the basic immune response, but also raised our awareness of the possible etiology and pathogenesis of diseases such as allergy, asthma, rheumatoid arthritis, and other auto-immune/immune system based diseases. The newly identified powerful cytokine networks, that regulate both innate and acquired immune responses, emerged as a result of the finding of new cell types such as innate lymphoid cells and iNKT. Identification of the novel cytokines and their networks has advanced our knowledge of the mechanisms involved in the maintenance of tissue homeostasis, including inflammation and tissue repair during stress and injury. The development of HIV vaccines has also seen dramatic changes over the last few years. There has been a shift from a sole focus on T cell vaccines to a holistic approach that pertains to the induction of both humoral and cellular elements. This entails the induction of antibodies - both binding and neutralizing - to prevent infection. The cellular vaccination produces a safety net of CD8+ T-cell responses to suppress the replication of the virus in the infected patients, and both of the effector arms are aided by helper T cells. From the perspective of clinical applications, significant advances have also been made in: oral immunotherapy for allergic disease, the possible treatment of HIV infection, the development of new monoclonal antibodies and their fragments to treat human diseases, and immune cell based therapies for cancer.
Leading researchers are specially invited to provide a complete understanding of a key topic within the multidisciplinary fields of physiology, biochemistry and pharmacology. In a form immediately useful to scientists, this periodical aims to filter, highlight and review the latest developments in these rapidly advancing fields. |
