These new volumes of Methods in Enzymology (554 and 555) on Hydrogen Sulfide Signaling continue the legacy established by previous volumes on another gasotransmitter, nitric oxide (Methods in Enzymology volumes 359, 396, 440, and 441), with quality chapters authored by leaders in the field of hydrogen sulfide research. These volumes of Methods in Enzymology were designed as a compendium for hydrogen sulfide detection methods, the pharmacological activity of hydrogen sulfide donors, the redox biochemistry of hydrogen sulfide and its metabolism in mammalian tissues, the mechanisms inherent in hydrogen sulfide cell signaling and transcriptional pathways, and cell signaling in specific systems, such as cardiovascular and nervous system as well as its function in inflammatory responses. Two chapters are also devoted to hydrogen sulfide in plants and a newcomer, molecular hydrogen, its function as a novel antioxidant. Continues the legacy of this premier serial with quality chapters on hydrogen sulfide research authored by leaders in the field Covers conventional and new hydrogen sulfide detection methods Covers the pharmacological activity of hydrogen sulfide donors Contains chapters on important topics on hydrogen sulfide modulation of cell signaling and transcriptional pathways, and the role of hydrogen sulfide in the cardiovascular and nervous systems and in inflammation

In the past few years there has been the increasing recognition that the effects of oxidative stress are not limited to the damage of cellular constituents. There is now evidence that reactive oxygen species (ROS) can alter cell function by acting upon the intermediates, or second messengers, in signal transductions. Such effects on signalling mechanisms probably account for the role of oxidative stress in inflammation, ageing, and cancer. The volume brings together researchers in both the major areas covered by the book, oxidative stress and signal transduction. The work is organized in three sections. The first deals with the immediate cellular responses to oxidative stress and the production of second messengers. The second details the connection between second messengers and the gene. The third part looks more closely at the level of the gene.

Free radicals are molecules with an unpaired electron in the outer shell or an electron that was damaged from either attack or from a poor splitting bond. After a free radical is formed it will continue to attack other molecules, which usually results in the damage of tissue or destruction of a healthy cell. Free radicals arise normally through metabolism. However, sometimes the body’s immune system will create them on purpose to neutralize viruses and bacteria. Free radicals are implicated in many ophthalmic disorders including uveitis, optic nerve damage, retinal ischemia, and macular degeneration. Free Radicals in Ophthalmic Disorders presents the most current knowledge pertaining to the role of free radicals/oxidants in ocular disorders, and the use of antioxidants in the prevention of these disorders.Written by today’s leading ocular scientists and clinicians, Free Radicals in Ophthalmic Disorders: gives comprehensive coverage of the role of free radicals/oxidants in ocular disorderscovers the use of antioxidants to prevent oxidative stress and ocular tissue damageexamines external factors that may result in the stimulation and heightened occurrence of free radicals/oxidants

Micronutrients and Brain Health addresses cutting-edge research related to processes of oxidative stress that affect brain function, an area of increasing significance for those concerned and involved with public health and translational medicine. Edited by four leading micronutrient researchers, the book brings together the investigative work of more than 70 leading researchers from across the world. Chapters identify brain-specific micronutrients that support function as well as the molecular mechanisms underlying their neuroprotectant activity. These explore age-related metabolic pathways, mitochondrial nutrients, neurodegeneration and micronutrients, cell signaling, and neuronal functions. General chapters are included on brain structure, function, and metabolism, while several other chapters are devoted to the role of specific micronutrients. The book explores how brain micronutrients are found to be both metabolic and redox regulators, thereby establishing a cross-talk between the major pathways involved in modulation of cell signaling and gene expression. Specific areas of research covered include: Uses of nutritional interventions to target age-related neuronal and behavioral deficitsEffects of various micronutrients on Alzheimer’s disease, including lipoic acid, green tea, and Ginkgo biloba extractsNutrients specific to essential mitochondrial functions Cognitive and behavioral consequences of iron deficiency with specific emphasis on women of reproductive ageOmega-3 fatty acids and their relation to brain function in the elderlyChallenges inherent in the development of neuroprotective-neurorescue drugs This book belongs to the groundbreaking CRC Press Series on Oxidative Stress and Disease. The series now includes more than two dozen volumes that address increasing evidence regarding the multiple ways that oxidative stress initiates and accelerates disease mechanisms. Most importantly, this book, like the series, offers invaluable information regarding nutritional and lifestyle choices, and pharmaceutical interventions that can be employed to prevent, control, and even ameliorate disease processes attributed to oxidative stress.

Mitochondria have traditionally been associated with metabolic functions; however recent research has uncovered a central role for these organelles in cell signaling, cell survival, and cell death. Mitochondrial dysfunction is a factor in a myriad of pathophysiological conditions, including age-related neurodegenerative disorders, cancer, metabolic syndrome, and cardiovascular disease. Mitochondrial Signaling in Health and Disease examines themes essential for the maintenance of the mitochondrial redox (reduction-oxidation) energy axis.With contributions from an impressive cadre of internationally recognized scientists, the book discusses coordinated mitochondrial functions that regulate cell function by discrete signaling pathways. Topics discussed include: Electron transport and energy productionMitochondrial biogenesis and dynamicsMitochondrial signalingApoptosis and autophagyPharmacology signalingEpigenetic signaling: mitochondrial methylation and acetylation reactionsAn essential resource for life and health scientists as well as pharmaceutical industry professionals, this volume highlights the importance of mitochondrial signaling and its role in establishing a harmonized communication between several cellular compartments. The information in this volume is critical to those developing mitochondrion-targeted therapies aimed at assuaging mitochondrial dysfunction or the specific factors contributing to its dysfunction.
