Book Description
Hydrogen sulfide (H2S) is a naturally occurring signaling molecule produced in vivo and plays a pivotal role in regulating a wide array of physiological processes. Additionally, emerging findings have illuminated that many of the biological effects initially attributed to H2S may actually stem from other reactive sulfur species (RSS), including hydropersulfides (RSSH) and various higher-order polysulfur species (RSSnH, RSSnR, and HSnH, where n > 1). These studies have underscored the contributions of these species to essential cellular processes, such as the efficient scavenging of reactive oxygen species and electrophiles, and their influence on mitochondrial function. Nonetheless, the chemistry of RSS remains challenging due to their inherently reactive nature, and their precise measurement within biological systems continues to pose a formidable challenge. This compilation of reprints focuses on recent advancements in the field of H2S/RSS chemical biology. It encompasses original research studies and comprehensive reviews, all geared towards exploring the therapeutic potential of H2S/RSS donors in the treatment of various conditions, including cancer, neurological disorders, and cardiovascular disease. Furthermore, it delves into the molecular mechanisms and physiological roles played by RSS along with the development of methodologies for quantifying and measuring the distribution of RSS within biological systems.

Book Description
This book is based on the papers presented at the "Fourth International Congress on Oxygen Radicals (4-ICOR)," held June 27 - July 3, 1987, at the University of California, La Jolla. The chapters deal with the phenomena associated with highly reactive oxygen species (hydroxy, peroxy, alkoxy, aroxy, and superoxide radicals, as well as singlet oxygen) and their peroxidation products (hydrogen peroxide, hydroperoxides, peroxides, and epoxides) as they relate to the fields of chemistry, food technology, nutrition, biology, pharmacology, and medicine. The kinetics, energetics, and mechanistic aspects of the reactions of these species and the interrelationship of oxygen radicals (or any other free radicals) and peroxidized products have been emphasized. Special attention is focused on the mechanisms of the generation of free radicals and peroxy products in biosystems and on the adverse effects of these radicals and products in humans. The topics span the continuum from the simple chemistry of model systems to the complex considerations of clinical medicine. The book also explores the mechanisms of agents that protect against free radicals and peroxy products in vitro and in vivo. These agents include antioxidants used in materials, food antioxidants, physiological antioxidants, and antioxienzymes (SOD, glutathione peroxidase, and catalases). The use of these inhibitors to prevent damage to organs being prepared for transplantation, thereby maintaining the quality of transplanted organs and/or extending their "shelf-life," also is examined.

Book Description
Vitamin E was discovered in 1922 by Evans and Bishop as an essential micronutrient for reproduction in rats. The active substance was isolated in 1936 by Evans and was named tocopherol, although the tocopherols and tocotrienols are actually a group of eight isomeric molecules that are characterized by a chromanol ring structure and a side chain. Providing an overview of the state-of-the-art of the chemistry of vitamin E, this book reflects the issues stemming from the complexity of the role and actions in vivo as well as in vitro. It summarizes information on the properties and function of vitamin E, the current understanding of the advantages and limitations of it, and also its application in promotion of health and prevention of diseases. Based on sound, solid scientific evidence, this is a timely addition to the literature as the centennial anniversary of the discovery of this important vitamin approaches.
