Book Description
Impairment of energy metabolism is a hallmark of brain aging and several neurodegenerative diseases, such as the Alzheimer’s disease (AD). Age- and disease-related hypometabolism is commonly associated with oxidative stress and they are both regarded as major contributors to the decline in synaptic plasticity and cognition. Neuroinflammatory changes, entailing microglial activation and elevated expression of inflammatory cytokines, also correlate with age-related cognitive decline. It is still under debate whether the mitochondrial dysfunction-induced metabolic deficits or the microglia activation-mediated neuroinflammation is the initiator of the cognitive changes in aging and AD. Nevertheless, multiple lines of evidence support the notion that mitochondrial dysfunction and chronic inflammation exacerbate each other, and these mechanistic diversities have cellular redox dysregulation as a common denominator. This research topic focuses on the role of a metabolic-inflammatory axis encompassing the bioenergetic activity, brain inflammatory responses and their redox regulation in healthy brain aging and neurodegenerative diseases. Dynamic interactions among these systems are reviewed in terms of their causative or in-tandem occurrence and how the systemic environment, –e.g., insulin resistance, diabetes, and systemic inflammation–, impacts on brain function.

Book Description
How can we slow the signs of aging? Although aging is a natural process for all living things, doing so without dramatic alterations of health and well-being is an important aim in health care. Understanding this gradual but continuous process is fundamental in order to avoid, or at least improve, aging associated illnesses and conditions. The reviews and studies compiled here address various aspects of the relationship between systemic and central changes during the aging process, with hormonal signals as the important liaison.

Book Description
Methodology and applications of redox proteomics The relatively new and rapidly changing field of redox proteomics has the potential to revolutionize how we diagnose disease, assess risks, determine prognoses, and target therapeutic strategies for people with inflammatory and aging-associated diseases. This collection brings together, in one comprehensive volume, a broad array of information and insights into normal and altered physiology, molecular mechanisms of disease states, and new applications of the rapidly evolving techniques of proteomics. Written by some of the finest investigators in this area, Redox Proteomics: From Protein Modifications to Cellular Dysfunction and Diseases examines the key topics of redox proteomics and redox control of cellular function, including: * The role of oxidized proteins in various disorders * Pioneering studies on the development of redox proteomics * Analytical methodologies for identification and structural characterization of proteins affected by oxidative/nitrosative modifications * The response and regulation of protein oxidation in different cell types * The pathological implications of protein oxidation for conditions, including asthma, cardiovascular disease, diabetes, preeclampsia, and Alzheimer's disease Distinguished by its in-depth discussions, balanced methodological approach, and emphasis on medical applications and diagnosis development, Redox Proteomics is a rich resource for all professionals with an interest in proteomics, cellular physiology and its alterations in disease states, and related fields.

Book Description
Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders. * Contains the latest information on the subject of neurodegenerative disorders* Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems

Book Description
The enteric nervous system (ENS) is a complex neural network embedded in the gut wall that orchestrates the reflex behaviors of the intestine. The ENS is often referred to as the “little brain” in the gut because the ENS is more similar in size, complexity and autonomy to the central nervous system (CNS) than other components of the autonomic nervous system. Like the brain, the ENS is composed of neurons that are surrounded by glial cells. Enteric glia are a unique type of peripheral glia that are similar to astrocytes of the CNS. Yet enteric glial cells also differ from astrocytes in many important ways. The roles of enteric glial cell populations in the gut are beginning to come to light and recent evidence implicates enteric glia in almost every aspect of gastrointestinal physiology and pathophysiology. However, elucidating the exact mechanisms by which enteric glia influence gastrointestinal physiology and identifying how those roles are altered during gastrointestinal pathophysiology remain areas of intense research. The purpose of this e-book is to provide an introduction to enteric glial cells and to act as a resource for ongoing studies on this fascinating population of glia. Table of Contents: Introduction / A Historical Perspective on Enteric Glia / Enteric Glia: The Astroglia of the Gut / Molecular Composition of Enteric Glia / Development of Enteric Glia / Functional Roles of Enteric Glia / Enteric Glia and Disease Processes in the Gut / Concluding Remarks / References / Author Biography

Book Description
Interest in the mind-body connection has grown in recent years, with accumulating evidence showing that the gut microbiome can alter behavioral, neural, and psychological outcomes. This publication brings together a group of international experts who are investigating the microbiome and its potential to contribute to the causes and treatment of mental illness. The contributions are not aimed solely at specialists in clinical and experimental neuroscience. They cover a range of key topics, including the role of the microbiome in mental health and specific psychiatric disorders that occur across the lifespan, interactions with the immune system, diet, and pharmacological interventions. Furthermore, the microbial metabolite production and the potential for psychobiotic interventions that target the microbiome to improve mental health outcomes are discussed. This book is unique in its focus on the mechanisms and consequences of the activities of gut microorganisms in mental health and illness, providing expert insight into the current state of the art and important future directions for this emerging area of research. Additionally, it provides an excellent knowledge base for newcomers and a refresher for researchers and clinicians working in the fields of neuroscience, psychology, or psychiatry.
