Xenobiotic Metabolic Enzymes Bioactivation and Antioxidant Defense
Xenobiotics are commonly referred to as xenobiotics that humans digest or inhale and are not produced by the body, such as foods, drugs, other chemicals, and air pollutants. Metabolic conversion of xenobiotics to facilitate their removal from the body is catalyzed by activation and detoxification enzymes. These enzymes are essential for bioactivation and detoxification of xenobiotics. Many xenobiotics are non-toxic in nature; however, some of them become cytotoxic or carcinogenic after metabolic conversion. Reactive intermediates or metabolites generated during metabolic conversion are generally electrophilic in nature and are either cations or neutral compounds, including reactive oxygen species and free radicals. Metabolic reactive intermediate-mediated oxidative stress can cause damages to cellular components such as impairment of protein functions, membrane lipid peroxidation, and formation of DNA adduct.
The Proteasome in Neurodegeneration
This book contains up-to-date reviews on different aspects of the ubiquitin proteasome system and its involvement in several neurodegenerative diseases. It is an indispensable source of information for scientists studying neurodegeneration. The book provides information on the basics of the ubiquitin proteasome system, but mainly describes a number of aspects of involvement of this system in neurodegeneration. All major hypotheses on the possible causes of neurodegeneration, such as oxidative stress, inflammation, and aging, are discussed in view of their effect on the ubiquitin proteasome system.
Reactive Oxygen Species in Plant Biology
This book highlights the latest advances made in the niche area of Reactive Oxygen Species and Redox processes in plants. It offers a valuable guide for researchers and students alike, providing insights into sensing, detox scavenging, the role in oxidative deterioration, and signaling associated with redox-regulatory processes in plants. The book also dramatically demonstrates how these amazingly resourceful molecular species and radicals are poised at the core of a sophisticated network of signaling pathways, and act as vital regulators of plants’ cell physiology and cellular responses to the environment. The molecular language associated with ROS-mediated signal transduction, which produces modulations in gene expression that determine plants’ stress acclamatory performance, is also discussed. The book subsequently provides information on current trends in redox proteomics and genomics, which include efforts to gain a fuller understanding of these redox players’ role in cellular processes, and to further the application of this knowledge to technology and agriculture. Given its scope and format, the book offers a valuable asset for students of Plant Sciences, Agriculture, and Molecular Biology, as well as readers engaged in research on and teaching ROS Biology.
OZONE : A New Medical Drug
Clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classic biochemical, physiological and pharmacological knowledge. Ozone is an oxidising molecule, a sort of superactive oxygen, which, by reacting with blood components, generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes, infections and cancer. Moreover ozone therapy, by inducing nitric oxide synthase, may mobilize endogenous stem cells, which will promote regeneration of ischaemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why, when properly used as a real drug within the therapeutic range, not only does not procure adverse effects but yields a feeling of wellness. Half of the book describes the value of ozone therapy in several diseases, particularly cutaneous infections and vascular diseases where ozone really behaves as a "wonder" drug.
Oxidative Stress in Aging : From Model Systems to Human Diseases
Oxidative Stress in Aging: From Model Systems to Human Diseases discusses the role of free radicals in aging in different animal models, as well as the relevance of free radicals on age-related diseases and pathological conditions in humans (following an introduction section of the basics and theory of free radicals). Human aging is a complex phenomenon - not everyone gets the same diseases and dies from the same cause. Accumulating reports implicate the connection between free radicals and various diseases and age-related pathological conditions. Although the causal relationships have not been established, it is necessary to discuss how free radicals are involved in each situation. In addition, the major interventions trials of antioxidant supplements in age-related disease, cancer and so forth are reviewed and discussed.
Oxidative Stress and Neuroprotection
This book deals with basic and clinical aspects of monoamine oxidase (MAO) subtypes A and B highlighting its importance in neurological and psychiatric diseases. Consequently the therapeutic actions of MAO-A and -B inhibitors in Parkinson’s disease (PK) and depression are the focus of several chapters. As MAO is the basis of the development of the "oxidative stress hypothesis" of PD, several chapters are devoted to iron and iron-induced oxidative stress in various experimental studies and clinical conditions. Based on these findings, new compounds have been developed which not only block MAO, but are in addition, either inhibitors of acetylcholine esterase or have iron chelating properties. The aspect of "preclinical" and "clinical" neuro protection as well as MAO neuroprotection are additional topics covered in this book. MAO, iron and neuroprotection are seen in the framework of general anti Parkinson’s therapy with chapters on levodopa, dopaminergic receptor agonists and clinical issues.
Oxidation : The Cornerstone of Carcinogenesis: Oxidation and Tobacco Smoke Carcinogenesis : A Relationship Between Cause and Effect
In order to learn oncology, it is necessary to acquire a comprehensive knowledge of molecular biology in carcinogenesis, and then, with this as a background, to consider the principles of the theoretical and clinical basis of the subject. For graduate students who are preparing themselves for the specialty of internal medicine or clinical oncology, and physicians who wish to become proficient in oncology, it is exceedingly difficult to be highly skilled and completely informed in this expanding field of science without a comprehensive text on the subject. This book is unique, due to its collective approach to the key aspects of the interdependency between three entities: oxidative stress, tobacco smoke and carcinogenesis, operating in a cause-effect sequence, in a concise and to the point manner. I hope this book will prove to be a helpful companion to the internist, the oncologist and the research scientist in molecular biology as well as a work of reference for the general practitioner and physician interested in cancer research.
Oxidants and Antioxidant Defense Systems
Oxidative stress is one of the major symptoms accompanying physiological functions and numerous diseases. Oxidants and free radicals are connected with diseases such as cancer, diabetes, infectious, cardiovascular and neurodegenerative diseases and also in the aging process itself. Therefore, comprehensive knowledge of the underlying mechanisms of oxidant and free radical production and the defence against this permanent threat to cells is important for the understanding of many physiological and pathophysiological processes. This book overviews the basic mechanisms of oxidant formation and antioxidant defences. In addition, the formation of oxidants and their detoxification, the damage of macromolecules and the major repair and removal systems will be highlighted.
Obesity and Cancer
This book highlights the concordance between signaling pathways that are involved in obesity and cancer cross-talks. It describes the role of cytokines, chemokines, growth factors, insulin, and adipokines in the development of obesity-associated cancers. The book reviews the role of inflammatory signaling pathways such as estrogen-mediated signaling, mTOR and AMP-activated protein kinase pathway and the involvement of adaptive and innate immunity, oxidative stress, gene polymorphism, dietary phytochemicals, and miRNAs in obesity and cancer. In addition, it covers the latest research on the drugs and natural therapeutic agents that target obesity-induced cancers and discusses various in vivo models for studying obesity and obesity-associated cancer. Lastly, it analyses the role of genetic polymorphisms in the obesity-related genes that influence cancer development.
Nutritional psychiatry
Provides a comprehensive overview of nutritional psychiatry, elucidating its theoretical foundations, the biological mechanisms linking diet to mental health (including inflammation, oxidative stress, disrupted energy metabolism the gut–brain axis and other implicated pathways), and the current evidence base for dietary impacts on major psychiatric disorders such as depression, anxiety, schizophrenia, bipolar disorder, and ADHD.
Neurodegeneration and Prion Disease
This volume provides an in-depth overview from world experts on prion disease. These fatal diseases include Creutzfeldt-Jakob disease, chronic wasting disease in deer, scrapie of sheep, bovine spongiform encephalopathy (mad cow’s disease) of cattle and related diseases. Understanding what causes neuronal death in these diseases is essential to both preventing and curing them. The most recent advances in understanding neuronal death in prion diseases are presented. Prion diseases serve as an experimental model for all neurodegenerative conditions. This book will provide understanding of neurodegeneration and provide an up-to-date record of the state of the art for other specialists and non-specialists in related fields.
Human semen analysis : From the WHO manual to the clinical management of infertile men
Intended to bridge the gap between the laboratory manual and the clinician by explaining in detail the test indication, its clinical utility, interpretation of results, and presenting a decision algorithm based on the test results. Thebook has 19 chapters grouped under seven sections that follow the chapters of the sixth edition of the WHO manual. Each chapter is written and reviewed by a team of senior clinicians, thus bringing a perspective that is truly clinically relevant. This book will be of great value to all clinicians involved in the management of male infertility and will also be of interest to laboratory scientists involved in semen testing by providing them with clinical perspectives of the test they perform. Human Semen Analysis: From the WHO Manual to the Clinical Management of Infertile Men is a useful guide for utilizing the WHO manual, interpreting test results, and deciding what subsequent clinical actions to take.
Handbook of nutrition and ophthalmology
The Handbook of Nutrition in Ophthalmology is the first general text on nutrition and eye health created for physicians, nutritionists, and researchers. Dr. Richard D. Semba provides important links between the epidemic of obesity and implications it has for eye disease and blindness. The volume addresses three broad themes throughout. The first is that a healthy diet as a major lifelong habit will likely have an impact on reducing a substantial portion of visual impairment and blindness. The second is that a historical perspective is essential to understanding current challenges in ophthalmology, medicine, and public health. The third theme is that many nutrients play a role in oxidative stress and inflammation, and this theory has emerged as a major underlying hypothesis in the pathogenesis of eye diseases.
Glucose-6-phosphate dehydrogenase deficiency
Glucose-6-phosphate dehydrogenase deficiency, the most common enzyme deficiency worldwide, causes a spectrum of disease including neonatal hyperbilirubinemia, acute hemolysis, and chronic hemolysis. Persons with this condition also may be asymptomatic. This X-linked inherited disorder most commonly affects persons of African, Asian, Mediterranean, or MiddleEastern descent. Because acute hemolysis is caused by exposure to an oxidative stressor in the form of an infection, oxidative drug, or fava beans, treatment is geared toward avoidance of these and other stressors.
Genotype - Proteotype - Phenotype Relationships in Neurodegenerative Diseases
Improved understanding of role of protein dysmetabolism in neurodegeneration promises to improve diagnoses, facilitate the development of biological markers relevant to disease pathophysiology, and provide tractable therapeutic targets. This Fondation IPSEN conference summary provides an update on the latest advances of the role of protein misfolding in the pathophysiology of neurodegenerative diseases.
Free-Radical-Induced DNA Damage and Its Repair : A Chemical Perspective
Understanding of the molecular basis of DNA damage and its repair has increased dramatically in recent years, and substantial knowledge now exists concerning the products arising from free-radical attack on DNA. Free-radical DNA damage may lead to mutations, cancer, and cell death. Free radicals have various sources, notably ionizing radiation and oxidative stress. In radiotherapy for cancer and with some anticancer drugs, use is made of cell death by excessive DNA damage. The mechanisms leading to products of free-radical attack which have been studied in models and with small double-stranded DNA fragments are discussed in detail, and the basics of the underlying free-radical chemistry are dealt with in separate chapters.
Effect of antioxidants in plant extracts and free radicals on blood sample
Antioxidants are substances that inhibit and regulate the formation of free radicals, and prevent or slow down the damage to cells caused by free radicals. There is a balance between antioxidants and free radicals throughout the body, and free radicals become dangerous when the balance is disturbed Free radicals play a key role in many physiological decisions in cells. Since free radicals are toxic to cellular components, it is known that they cause DNA damage, contribute to DNA instability and mutation and thus favor carcinogenesis.Low levels of free radicals and steady state levels of antioxidant enzymes are responsible for the fine tuning of redox status inside cells. A change in redox state is a way to modify the physiological status of the cell.Many healthful foods contain antioxidants. If a person consumes some or all of these foods regularly, they may increase their antioxidant levels, potentially helping them prevent the damage that doctors associate with oxidative stress.
L’insuffisance rénale aiguë = Acute renal failure
The aim of this book is to make current data from the experimental and clinical literature accessible to readers. More than a thousand articles are published each year on the theme and the authors aim to synthesize this information. These data relate in particular to the identification of early markers of renal dysfunction without which screening, recognition of the main pathophysiological determinants and prevention remain uncertain. This book focuses attention on clinical situations characterized by the renal impact of the main dysfunctions of vital functions, the prognosis of which is worsened by the occurrence of this renal failure. The following will be treated in particular: the renal consequences of oxidative stress, the renal consequences of respiratory dysfunction, cardiac dysfunction, hepatic dysfunction, alterations in hemostasis, septic shock and hemorrhagic shock. Finally, the physiopathological data from experimental models are gradually finding their echo in the clinical field, opening up therapeutic avenues whose recent evaluations will be analyzed.
Cigarette Smoke and Oxidative Stress
From a public health point of view, there is little doubt that one of the most important preventable causes of disease worldwide is tobacco smoking. From a scientifc point of view, we found it of interest to make a comprehensive ov- view of what we presently know about oxidative stress and tobacco smoke, because sm- ing is presently the best-known common condition associated with oxidative stress, and it may serve as a model for others. To this end, we have asked distinguished researchers from the public and the private sectors to evaluate the present scientifc status in their particular area. Authors were selected purely because of their scientifc merits.
