Book excerpt: Over activation of the sympathetic nervous system is prevalent in many forms of cardiovascular disease such as chronic heart failure (CHF) and hypertension. Although increased neuronal renin-angiotensin system activity in presympathetic neurons has been well implicated in mediating this sympatho-excitation, many of the neuronal effects of angiotensin II (Ang II) signaling remain poorly understood. One particular mechanism of Ang II-mediated increases in presympathetic neuronal activity is through reductions in voltage-gated K+ currents. Another pathway that has profound effects on neuronal K+ currents and that has been previously implicated in Ang II-signaling is brain-derived neurotrophic factor (BDNF) activity through its receptor tyrosine kinase B (TrkB). Therefore, we hypothesized that BDNF/TrkB signaling is an important mediator of the neuronal effects of Ang II in modulating voltage-gated K+ currents and autonomic dysfunction in cardiovascular disease states such as CHF and hypertension. We employed cell culture and whole-animal models to explore this hypothesis and utilized electrophysiological, molecular, and in vivo physiological techniques. Patch-clamp studies demonstrated that BDNF is involved in Ang II-induced reductions to K+ currents. Further in-vivo experiments found that overexpression of Kv4.3 into the rostral ventrolateral medulla attenuates the increase in sympathetic nerve activity of rats post-myocardial infarction. Baroreflex dysfunction is common in CHF, and desensitization of central neuronal areas such as the nucleus tractus solitarius (NTS) can mediate this dysfunction. We therefore hypothesized that changes in BDNF/TrkB signaling in the NTS mediated baroreflex dysfunction in CHF. Blocking TrkB with ANA-12 in the NTS blunted baroreflex sensitivity in sham rats but had little effect on the already blunted baroreflex sensitivity of CHF rats. TrkB expression was reduced in CHF rats, implicating reduced BDNF/TrkB signaling in the NTS as a mechanism for reduced baroreflex sensitivity during CHF. In a final set of experiments we explored the connection between Ang II and BDNF in vivo. Central administration of Ang II increased mean arterial pressure and induced sympatho-excitation, both of which were attenuated by coinfusion of ANA-12. Overall, these data implicate BDNF as an important factor in mediating the neuronal effects of Ang II on K+ currents, hemodynamics, baroreflex sensitivity, and sympathetic nerve activity.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Available in PDF, EPUB and Kindle. Book excerpt: Most cancer deaths are a result of metastasis. The spread of a primary tumor to colonize neighboring and distant organs is the relentless endgame that defines the neoplastic process. Patients who have been diagnosed with cancer are treated to prevent both the recurrence of the tumor at the site of origin and metastasis that would re-stage them as advanced stage IV cancer. Historically and still with some types of cancer, stage IV is perceived by patients as “terminal.” Fortunately, recent molecular therapies have extended the lives of patients with advanced cancer and reassuringly people living with metastatic disease increasingly visit our clinics. What is the path forward? Given that the consilience of science and medicine is a dynamic art from which therapies arise, it would be misguided to consider any single work adequate at capturing the horizon for research. So with humility we constructed this text as primer for scientists. It begins with a broad introduction to the clinical management of common cancers. This is intended to serve as a foundation for investigators to consider when developing basic science hypotheses. Unquestionably, medical and surgical care of cancer patients reveals biology and dictates how novel therapeutics will ultimately be evaluated in clinical trials. The second section of this text offers provocative and evolving insights that underscore the breadth of science involved in the elucidation of cancer metastasis biology. The text concludes with information that integrates scientific and clinical foundations to highlight translational research. This book serves as a framework for scientists to conceptualize clinical and translational knowledge on the complexity of disease that is metastatic cancer.

Book excerpt: In recent decades, it has become increasingly clear that the immune and nervous systems communicate with each other in a bidirectional way. The role of chronic stress in allergic disease and inflammation has been confirmed and raises the important question of how psychosocial factors influence the outcome of allergic conditions.This book explains the roles of the autonomic, peripheral and central nervous systems in allergy and asthma. With contributions from leading authorities - both clinicians and basic researchers - it covers a wide range of topics from psychology over epigenetics to brain imaging. The 15 invited reviews discuss topics such as the role of stress in allergy and asthma, the concept of programming in utero and in childhood and adulthood, the significance of neurotrophins, and the involvement of the nervous system in the lung in asthma and lung inflammation. The interactions between mast cells and the nervous system are examined as well as the role of the gut microbiome in regulating the hypothalamic-pituitary-adrenal axis and the stress response. Further chapters are devoted to neural and behavioral changes associated with food allergy, the role of the neuroendocrine system in the skin, and the way in which itch is processed by the brain.Unique in its field, this valuable volume is recommended reading not only for allergologists, psychologists specializing in allergy and somatic manifestations, respirologists and asthma researchers, but for anyone interested in psychoneuroimmunology.

Available in PDF, EPUB and Kindle. Book excerpt: With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.

Available in PDF, EPUB and Kindle. Book excerpt: This entry in the Oxford Library of Psychology compiles cutting- edge research organized around the concept "molecular psychology," which applies principles of molecular biology to the study of behavior and its neural underpinnings. Determining the biological bases for behavior, and the extent to which we can observe and explain their neural underpinnings, requires a bold, broadly defined research methodology. The interdisciplinary entries in this handbook are organized around the principle of "molecular psychology," which unites cutting-edge research from such wide-ranging disciplines as clinical neuroscience and genetics, psychology, behavioral neuroscience, and neuroethology. For the first time in a single volume, leaders in diverse research areas use molecular approaches to investigate social behavior, psychopathology, emotion, cognition and stress in healthy volunteers, patient populations, and an array of non-human species including rodents, insects, fish, and non-human primates. Chapters draw on molecular methods covering candidate genes, genome-wide association studies, copy number variations, gene expression studies, and epigenetics while addressing the ethical, legal, and social issues to emerge from this new and exciting research approach.

Book excerpt: Neurocardiovascular diseases and disturbances are a distinguished group of the pathological entities that demand an integrative scientific approach to be studied, treated and finally, cured. Brain-heart and vessels axes can be comprehended as a complex, bidirectional unit of utmost importance for organism survival. Harmonized functioning of this unit through the autonomic nervous system interface can be fatally compromised by stress, infection, systemic diseases, dietary habits, pharmacological and surgical interventions. The scope of this Research Topic is to emphasize the importance of the scientists’ and medical practitioners’ attention to molecular and systemic modes of the brain-heart and vessels functioning and, often underestimated, neurocardiovascular pathology by a patient’s bedside. In the last couple of decades, this research area flourished and contributed to the general knowledge by placing the new milestones neurocardiovascular physiology and pathology. We hope that by this modest contribution we will provide an interesting, practical and innovative update on the novelties in the field of neurocardiovascular research.

Book excerpt: The book describes how the balance between pro- and anti-inflammatory molecules is related to health and disease. It is suggested that many diseases are initiated and their progress is influenced by inflammatory molecules and a decrease in the production and/or action of anti-inflammatory molecules and this imbalance between pro- and anti-inflammatory molecules seems to have been initiated in the perinatal period. This implies that strategies to prevent and manage various adult diseases should start in the perinatal period. An alteration in the metaolism of essential fatty acids and their anti-inflammatory molecules such as lipoxins, resolvins, protecitns, maresins and nitrolipids seems to play a major role in the pathobiology of several adult diseases. Based on these concepts, novel therapeutic approaches in the management of insulin resistance, obesity, type 2 diabetes mellitus, metabolic syndrome, cancer, lupus, rheumatoid arthritis and other auto-immune diseases are presented. Based on all these evidences, a unified concept that several adult diseases are due to an alteration in the balance between pro- and anti-inflammatory molecules is discussed and novel methods of their management are presented.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to present a focused approach to the pathophysiology, diagnosis, and management of the most common autonomic disorders that may present to the clinical neurologist. Autonomic Neurology is divided into 3 sections. The first section includes 5 chapters reviewing the anatomical and biochemical mechanisms of central and peripheral nervous system control of autonomic function, principles of autonomic pharmacology, and a clinical and laboratory approach to the diagnosis of autonomic disorders. The second section focuses on the pathophysiology and management of orthostatic hypotension, postural tachycardia, baroreflex failure; syncope, disorders of sweating, neurogenic bladder and sexual dysfunction, gastrointestinal dysmotility, and autonomic hyperactivity. The final section is devoted to specific autonomic disorders, including central neurodegenerative disorders; common peripheral neuropathies with prominent autonomic failure; painful small fiber neuropathies; autoimmune autonomic ganglionopathies and neuropathies; focal brain disorders; focal spinal cord disorders; and chronic pain disorders with autonomic manifestations. This book is the product of the extensive experience of its contributors in the evaluation and management of the many patients with autonomic symptoms who are referred for neurologic consultation at Mayo Clinic in Rochester, Minnesota. Autonomic Neurology focuses on clinical scenarios and presentation of clinical cases and includes several figures showing the results of normal and abnormal autonomic testing in typical conditions. Its abundance of tables summarizing the differential diagnosis, testing, and management of autonomic disorders also help set this book apart from other books focused on the autonomic nervous system.

Available in PDF, EPUB and Kindle. Book excerpt: The first report that rapid eye movements occur in sleep in humans was published in 1953. The research journey from this point to the realization that sleep consists of two entirely independent states of being (eventually labeled REM sleep and non-REM sleep) was convoluted, but by 1960 the fundamental duality of sleep was well established including the description of REM sleep in cats associated with “wide awake” EEG patterns and EMG suppression. The first report linking REM sleep to a pathology occurred in 1961 and a clear association of sleep onset REM periods, cataplexy, hypnagogic hallucinations and sleep paralysis was fully established by 1966. When a naïve individual happens to observe a full-blown cataplexy attack, it is both dramatic and unnerving. Usually the observer assumes that the loss of muscle tone represents syncope or seizure. In order to educate health professionals and the general public, Christian Guilleminault and I made movies of full-blown cataplectic episodes (not an easy task). We showed these movies of cataplexy attacks to a number of professional audiences, and were eventually rewarded with the report of a similar abrupt loss of muscle tone in a dog. We were able to bring the dog to Stanford University and with this as the trigger, we were able to develop the Stanford Canine Narcolepsy Colony. Breeding studies revealed the genetic determinants of canine narcolepsy, an autosomal recessive gene we termed canarc1. Emmanuel Mignot took over the colony in 1986 and began sequencing DNA, finally isolating canarc1 in 1999.
