Book Description
This book comprehensively reviews the association of homocysteine metabolism with the etiology of various human disorders. The well-defined chapters embedded the central and peripheral effects of homocysteine metabolism intricately related with cardiovascular, neurodegenerative, metabolic, and autoimmune disorders. Further, it discusses the mechanisms of perturbance of cellular proteostasis by elevated homocysteine levels and provides a comprehensive account of pathophysiological consequences and clinical implications of homocysteine-containing proteins. The book also reviews association of genetic variants of homocysteine metabolic genes with type 2 diabetes mellitus and obesity. It also describes the molecular mechanism of hyperhomocysteinemia in the negative/feedback regulation of neural stem cell proliferation and alterations in DNA methylation. Taken together, it summarizes the mechanisms of hyper homocysteinemia-induced endothelial dysfunction and physiological functions of hydrogen sulfide as the protective agent.

Book Description
This is an important and timely volume. The history of research in homocysteine metabolism can be divided into three periods. The first phase was the exploration of the individual reactions and metabolites that characterize the transmethylation and transsulfuration sequences. The former originated with his description of the biosynthesis of methylpyridine and culminated in the work of Cantoni and Axelrod. Similarly the finding that insulin contained cystine was a potent catalyst for the metabolic and nutritional studies of Rose and du Vigneaud. The description and the definition of homocystinuria, a rare inherited meta bolic disorder, marked the beginning of the second historical period. Where previously there had been few laboratories located largely in the United States soon there were numerous research groups representing many nationalities. The more intense focus led to major advances, both in the laboratory and in the clinics. Studies of afflicted individuals, when combined with investigations in experimental animals, provided the basis for a concept of methionine metabo lism that encompassed both transmethylation and transsulfuration. The central role of homocysteine was apparent.

Book Description
Excess of homocysteine, a product of the metabolism of the essential amino acid methionine, is associated with poor health, is linked to heart and brain diseases in general human populations, and accelerates mortality in heart disease patients. Neurological and cardiovascular abnormalities occur in patients with severe genetic hyperhomocysteinemia and lead to premature death due to vascular complications. Although it is considered a non-protein amino acid, studies over the past dozen years have discovered mechanisms by which homocysteine becomes a component of proteins. Homocysteine-containing proteins lose their normal biological function and become auto-immunogenic and pro-thrombotic. In this book, the author, a pioneer and a leading contributor to the field, describes up-to date studies of the biological chemistry of homocysteine-containing proteins, as well as pathological consequences and clinical implications of their formation. This is a comprehensive account of the broad range of basic science and medical implications of homocysteine-containing proteins for health and disease. ​

Book Description
More than 30 years ago, a young Harvard pathologist offered the medical community a theory for the cause of one of today's biggest killers-- heart disease. It is called the Homocysteine Theory and is the medical breakthrough that inspired Andrew Weil to label Dr. McCully as a visionary medical pioneer well ahead of his time. This discovery has the potential to save millions, yet ironically destroyed Dr. McCully's medical career. Homocysteine, a byproduct of metabolism, has been discovered to be a better risk indicator of heart disease than high cholesterol. A simple B6 vitamin and folic acid play a major role in controlling homocysteine levels. This proven theory will change the way the medical establishment views and treats heart disease. Today, the medical community is beginning to accept Dr. McCully's findings transforming his story from medical heresy to legitimate medicine. Updated and revised, complete with a new introduction by Walter Wilett, this eye opening book combines Dr. McCully's personal story and scientific philosophy with a fascinating exposition of his discovery and a special program to make use of this information to improve overall health.

Book Description
Elevated blood concentrations of homocysteine, B vitamins deficiencies and oxidative stress are etiological factors for many human chronic diseases, yet the etiologic relationship of hyperhomocysteinemia to these disorders remains poorly understood. Clinical trials continue to support the notion that hyperhomocysteinemia is involved in the pathogenesis of oxidative stress and its associated impairment of cellular redox status. Antioxidants, phytochemicals, and bioactive agents are thought to be associated with the reduction of oxidative stress and reducing risk of chronic diseases, yet their role in preventing hyperhomocysteinemia-mediated oxidative stress has not been well covered in the literature. Nutritional Management and Metabolic Aspects and of Hyperhomocysteinemia comprehensively covers the nutritional-based intervention for combating hyperhomocysteinemia-mediated oxidative stress, metabolic regulation of homocysteine-dependent transulfuration and transmethylation pathways, and the identification of novel biomarkers for early diagnosis of hyperhomocysteinemia. The main goal of this text is to address the biochemical and nutritional aspects of hyperhomocysteinemia in relation to increasing risk of chronic diseases, providing insight into the etiology of hyperhomocysteinemia and covering new research on the effective reduction and management of hyperhomocysteinemia-associated chronic diseases. For researchers seeking a singular source for the understanding of the biochemical aspects and nutrition-based combat of hyperhomocysteinemia, its risk factors, preventive measures, and possible treatments currently available, this text provides all of the important needed information in up-to-date and comprehensive form.

Book Description
The complex roles of glutathione and sulfur amino acids in human health Glutathione (γ-L-glutamyl-L-cysteinylglycine, GSH) is a major antioxidant acting as a free radical scavenger that protects the cell from reactive oxygen species (ROS). Sulfur amino acids (SAAs), such as methionine and cysteine, play a critical role in the maintenance of health. GSH depletion as well as alterations of SAA metabolism are linked to a host of disease states including liver cirrhosis, various pulmonary diseases, myocardial ischemia and reperfusion injury, aging, Parkinson's disease, Alzheimer's disease, sepsis, and others. This book provides researchers with a comprehensive review of the biochemistry, absorption, metabolism, biological activities, disease prevention, and health promotion of glutathione and sulfur amino acids. The twenty-two chapters explore such topics as: Chemistry, absorption, transport, and metabolism of GSH and sulfur amino acids Antioxidant and detoxification properties of GSH and sulfur amino acids, highlighting the enzymatic systems involved in antioxidant defenses Biological activities of GSH and sulfur amino acids and their role in modulating cell processes Role of GSH and sulfur amino acid deficiency and alteration in the onset of diseases and in aging Protective effects exerted by GSH and sulfur amino acids when used as drugs, functional foods, and nutraceuticals in humans and animals Special attention is paid to the molecular mechanisms for the modulation of transcription factors and enzyme activities, as well as the nutritional and therapeutic significance of dietary sulfur amino acids as shown in human and animal models. With more than 2,000 scientific references, this book provides food scientists, nutritionists, biochemists, food technologists, chemists, molecular biologists, and public health professionals with a comprehensive and up-to-date examination of glutathione and sulfur amino acids in human health and disease.

Book Description
The first description of homocysteine (Hcy), a non-proteinogenic amino acid, was introduced in a case study more than 70 years ago. In recent years, numerous studies have shown a positive correlation between serum levels and various diseases, especially vascular pathology. Vitamins B6, B12, and folic acid play a major role in controlling homocysteine levels. In this book are presented both methods for the determination of homocysteine and its involvement in human pathology. Homocysteine levels can be taken as an early indicator for the detection of cardiovascular diseases because Hcy levels increase after a myocardial infarction or stroke.
