Redox homeostasis results from the balance between the production of reactive species (e.g. ROS, RNS, etc) and their detoxification by endogenous or exogenous antioxidants. ROS play several important physiological roles, however, their excessive production or impaired detoxification is associated with oxidative stress and cellular injury. Importantly, oxidative damage to vulnerable central nervous system (CNS) cells is a common pathological feature of several neurodegenerative diseases. Antioxidants have been considered as attractive potential therapeutic agents to prevent or halt disease progression but the clinical efficacy of antioxidant treatment strategies is still marginal. Improvement of antioxidant therapy effectiveness might involve adjustment of preclinical to clinical settings and development of new efficient delivery methods and will require a more in-depth knowledge of cellular redox-signaling mechanisms. Promising novel redox-based therapeutic strategies are gaining relevance to combat oxidative stress associated with neurodegenerative diseases. These include boosting the endogenous antioxidant machinery through activation of the antioxidant master regulator Nrf2 (nuclear factor erythroid 2-related factor 2) or modulation of ROS production by NOX (nicotinamide adenine dinucleotide phosphate (NADPH) oxidase) inhibitors. Redox regulation of key cellular functions is currently recognized as an important cellular signaling mechanism and events such as post-translational modifications (e.g. S_glutathionylation, S_nitrosylation, glycosylation, etc) play important roles in redox signal transduction and might be instrumental to uncover pathological mechanisms and identify novel therapeutic targets in neurodegenerative diseases. This Research Topic focuses on redox signaling mechanisms and aims to provide novel insights into the role of redox-signaling, with particular emphasis on redox regulation involving post-translational modifications, in the pathophysiology of neurodegenerative diseases. Moreover, it aims to present an overview of the potential of antioxidants as therapeutics for CNS disorders with a special focus on emerging novel therapeutic redox-based strategies. We are particularly interested in studies: -addressing new redox-based molecular mechanisms contributing to neurodegenerative diseases; -exploring the role of naturally occurring compounds, standard medications, and nutraceuticals with antioxidant properties in modulating redox-signaling pathways and limiting and/or preventing oxidative damage associated with these disorders; -addressing mechanistically the role of post-translational modifications in the pathophysiology of neurodegenerative disorders.

This book aims to present the age-related alterations in redox signaling networks and their diagnostic biomarkers in aging cells using multidisciplinary approach. Establishing sensitive and specific biomarkers of dynamic redox homeostasis is crucially important in the development of effective antiaging and senolytic interventions. Recent years have seen tremendous advances in the understanding of redox signaling events which highlight the process of aging and age-related pathologies. A major challenge in biological aging research is developing reliable biomarkers to determine the consequences of disrupted redox signaling networks long before the clinical diagnosis of age-related diseases is made. Therefore, we have chosen to concentrate on aging-induced aberrant redox signaling networks, their biomarkers, and pathological consequences in this book. Although oxidation is a natural metabolic process, the imbalance in the level of oxidants and antioxidants causes oxidative stress and eventually leads to inflammatory conditions, diabetes, neurodegenerative diseases, and cancer. Novel redox-sensitive biomarkers for the evaluation of aging-induced proteinopathies such as amyloid ß and tau proteins in Alzheimer's disease, α-synuclein in Parkinson's disease, and islet amyloid polypeptides in type 2 diabetes mellitus recently drew the attention of researchers. Inside this textbook, readers will find comprehensive perspectives on the association between redox homeostasis and the aging process both at the molecular and clinical levels. Due to the inherent relationship between impaired metabolic activities and oxidative stress, the temporal interaction between intermediary metabolism and disturbed redox status can lead to greater susceptibility to aging-induced diseases and disorders, such as cardiovascular diseases, hypertension, and diabetes. This knowledge could be a key to continued research toward improving medication regimens such as in cancer and cardiovascular therapies, and procedural outcomes for patients. This book brings together current research evidence and knowledge on redox signaling and biomarkers in aging in chapters written by leading global experts in this rapidly evolving field. We hope that this textbook is of interest to a wide group of researchers, advanced students, scientifically curious non-specialist readers and clinicians alike.

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

The editor of this volume, having research interests in the field of ROS production and the damage to cellular systems, has identified a number of enzymes showing ·OH scavenging activities details of which are anticipated to be published in the near future as confirmatory experiments are awaited. It is hoped that the information presented in this book on NDs will stimulate both expert and novice researchers in the field with excellent overviews of the current status of research and pointers to future research goals. Clinicians, nurses as well as families and caregivers should also benefit from the material presented in handling and treating their specialised cases. Also the insights gained should be valuable for further understanding of the diseases at molecular levels and should lead to development of new biomarkers, novel diagnostic tools and more effective therapeutic drugs to treat the clinical problems raised by these devastating diseases.

In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease. The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics and so on. The chapters are written by national or international experts and specialists.

This comprehensive volume examines the current state of free radical biology and its impact on otology, laryngology, and head and neck function. The chapters collectively highlight the interrelationship of basic and translational studies in each area, define the challenges to translation, and identify the existing basic issues that demand investigation as well as the opportunities for novel intervention to prevent and treat ENT pathology and impairment. In each chapter, or in some cases pairs of chapters, the author(s) have included or married issues of basic research with translational challenges and research, thus defining the pathway by which new basic insights may lead to interventions to prevent or treat impairment. The final chapter of this book reflects a meeting of all the contributors, culminating in a discussion and “white paper” that identifies the challenges to the field and defines the studies and collaborations that may lead to improved understanding of free radical biology in ENT and, subsequently, new interventions to medically treat ENT pathology.

Alzheimer’s disease is an increasingly common form of dementia and despite rising interest in discovery of novel treatments and investigation into aetiology, there are no currently approved treatments that directly tackle the causes of the condition. Due to its multifactorial pathogenesis, current treatments are directed against symptoms and even precise diagnosis remains difficult as the majority of cases are diagnosed symptomatically and usually confirmed only by autopsy. Alzheimer’s Disease: Recent Findings in Pathophysiology, Diagnostic and Therapeutic Modalities provides a comprehensive overview from aetiology and neurochemistry to diagnosis, evaluation and management of Alzheimer's disease, and latest therapeutic approaches. Intended to provide an introduction to all aspects of the disease and latest developments, this book is ideal for students, postgraduates and researchers in neurochemistry, neurological drug discovery and Alzheimer’s disease.

Neurodegenerative diseases are debilitating disorders defined as loss of function or progressive destructing structure of the nervous system with high prevalence among the aging population. These diseases mainly include Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and amyotrophic lateral sclerosis (ALS). They are significantly associated with age and degeneration, becoming a devastating global health issue as a result of the growth of mean life expectancy worldwide. Few or no effective treatments are available for age-related neurodegenerative diseases, causing large socioeconomic and personal costs. The last 15 years have seen a boom in the use and integration of “omic” approaches (such as genomic, transcriptomic, epigenomic and metabolomic techniques) to study neurodegenerative disease in an unprecedented way. While, to date, no therapy based on these approaches is available to cure neurodegenerative diseases. Therefore, it is necessary to search for new, safe, and effective drug candidates and treatment strategies. In this Research Topic, our prime focus would be on the use and integration of “omic” approaches to study biomarkers, pathogenesis, disease progression and new therapeutic target of neurodegenerative diseases, so as to search for new, safe, and effective drug candidates.
