Book Description
This book will be the first book that presents the beneficial effects of hydrogen sulfide in the treatment of various kidney pathologies. Hydrogen sulfide (H2S), a gas with a distinctive smell of rotten eggs, was known for over three centuries for its toxicity and death at high concentrations especially among agricultural and industrial workers. This is due to its ability to reversibly antagonize complex IV of the mitochondrial electron transport chain. However, studies over the past two decades have shown that H2S has risen above its historic notorious label and has received significant experimental attention as an endogenously produced gaseous signaling molecule that plays an important role in cellular homeostasis and influences a myriad of physiological and pathological processes at low concentrations. Its production is enzymatically regulated and has specific molecular targets. Several recent in vitro and in vivo studies have demonstrated that at low micromolar concentrations, H2S exhibits important therapeutic characteristics that target multiple molecular pathways and thereby preventing the development and progression of several pathologies. This beneficial effect of H2S suggests that it may meet the demand for alternative and/or additional therapeutic agents against various renal pathologies in which reduced levels of renal and plasma H2S were observed. Interestingly, while the distribution of H2S-producing enzymes is tissue-specific, they are abundantly expressed in the glomeruli and in the brush border and cytoplasm of epithelial cells of the renal tubules and in the peritubular capillaries. This makes the kidney a rich source of endogenous H2S production. From pre-clinical and clinical perspectives, this book is topical and timely, and seeks to lay the foundation for future clinical applications of H2S in nephrology.

Book Description
This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.

Book Description
On-board fires can occur on submarines after events such as collision or explosion. These fires expose crew members to toxic concentrations of combustion products such as ammonia, carbon monoxide, hydrogen chloride, and hydrogen sulfide. Exposure to these substances at high concentrations may cause toxic effects to the respiratory and central nervous system; leading possible to death. T protect crew members on disabled submarines, scientists at the U.S. Navy Health Research Center's Toxicology Detachment have proposed two exposure levels, called submarine escape action level (SEAL) 1 and SEAL 2, for each substance. SEAL 1 is the maximum concentration of a gas in a disabled submarine below which healthy submariners can be exposed for up to 10 days without encountering irreversible health effects while SEAL 2 the maximum concentration of a gas in below which healthy submariners can be exposed for up to 24 hours without experiencing irreversible health effects. SEAL 1 and SEAL 2 will not impair the functions of the respiratory system and central nervous system to the extent of impairing the ability of crew members in a disabled submarine to escape, be rescued, or perform specific tasks. Hoping to better protect the safety of submariners, the chief of the Bureau of Medicine and Surgery requested that the National Research Council (NRC) review the available toxicologic and epidemiologic data on eight gases that are likely to be produced in a disabled submarine and to evaluate independently the scientific validity of the Navy's proposed SEALs for those gases. The NRC assigned the task to the Committee on Toxicology's (COT's) Subcommittee on Submarine Escape Action Levels. The specific task of the subcommittee was to review the toxicologic, epidemiologic, and related data on ammonia, carbon monoxide, chlorine, hydrogen chloride, hydrogen cyanide, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide in order to validate the Navy's proposed SEALs. The subcommittee also considered the implications of exposures at hyperbaric conditions and potential interactions between the eight gases. Review of Submarine Escape Action Levels for Selected Chemicals presents the subcommittee's findings after evaluation human data from experimental, occupational, and epidemiologic studies; data from accident reports; and experimental-animal data. The evaluations focused primarily on high-concentration inhalation exposure studies. The subcommittee's recommended SEALs are based solely on scientific data relevant to health effects. The report includes the recommendations for each gas as determined by the subcommittee as well as the Navy's original instructions for these substances.

Book Description
The metabolism of sulfur especially by sulfurtransferases had been intensively studied in mid 1900’s. Three enzymes, cystathionine β–synthase (CBS), cystathionine γ–lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3MST) were found to have the capacity to produce H2S in vitro. However, H2S was recognized simply as a by-product of the metabolic pathways or as a marker for evaluating the activity of enzymes rather than as a physiological active molecule. In the late 1980’s relatively high concentrations of sulfide were measured in the brain that led to the successive studies of identifying the physiological functions of H2S. Recently, the steady-state concentrations of H2S have been re-evaluated and found to be much less than that initially measured. However, despite these differences, such re-evaluations served to further confirm the existence of H2S in mammalian tissues. H2S is produced in almost every organ and plays various roles such as neuromodulation, vasodilation, insulin release, inflammation, angiogenesis and cytoprotection. The unregulated production of H2S and improper responses of target molecules are involved in the pathogenesis of various diseases. This book focuses on these topics as well as on the recent progress in the biology and the therapeutic development of this molecule.

Book Description
Due to population aging, calcific aortic valve disease (CAVD) has become the most common heart valve disease in Western countries. No therapies exist to slow this disease progression, and surgical valve replacement is the only effective treatment. Calcific Aortic Valve Disease covers the contemporary understanding of basic valve biology and the mechanisms of CAVD, provides novel insights into the genetics, proteomics, and metabolomics of CAVD, depicts new strategies in heart valve tissue engineering and regenerative medicine, and explores current treatment approaches. As we are on the verge of understanding the mechanisms of CAVD, we hope that this book will enable readers to comprehend our current knowledge and focus on the possibility of preventing disease progression in the future.
