This book has been developed from its earlier and far less formal presentment as the proceedings of a symposium entitled The Biochemistry of S-Adenosylmethionine as a Basis for Drug Design that was held at the Solstrand Fjord Hotel in Bergen, Norway on June 30-July 4, 1985. The purpose of the symposium was to bring together scientists from various disciplines (biochemistry, pharmacology, virology, immunology, chemistry, medicine, and so on) to discuss the recent advances that have been made in our understanding of the biological roles of S adenosylmethionine (AdoMet) and to discuss the feasibility of utilizing AdoMet-dependent enzymes as targets for drug design. Thus the information provided...
Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme in both folate and homocysteine metabolism. It first achieved medical recognition in 1972 with the report of severe deficiency of MTHFR in a patient with homocystinuria, an inborn error of metabolism characterized by marked elevation of homocyst(e)ine in plasma and urine. Although the majority of cases of homocystinuria are due to a deficiency of the first enzyme in the transsulfuration pathway for homocysteine metabolism, cystathionine-ß-synthase (CBS), disruption of homocysteine remethylation to methionine can also result in homocystinuria. With the identification of additional patients with severe MTHFR deficiency, the heterogeneity of this disorder became manifest. This book covers many of the complex traits that have been reported to be influenced by the well-characterized 677C→T variant; there is less information on the 1298A→C variant, but it is discussed where appropriate. It is quite surprising, and unique, that a single variant should influence such a wide variety of clinical conditions.
This volume is the first comprehensive treatise on homocysteine to treat the topic from the basic biochemical, metabolic, genetic, and dietary determinants to disease relationships, including concepts of pathogenesis. In addition, the public health implications of these associations are described. To date, evidence strongly supports the hypotheses that Hyperhomocysteinemia is a strong independent determinant of vascular disease and Many cases of hyperhomocysteinemia are amenable to homocysteine-lowering treatment with B-vitamins.£/LIST£ The strength of this evidence is prompting discussion of large-scale homocysteine-lowering interventions. Against this background of growing recognition of...
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. Whe...
This is an unusually comprehensive 2001 account of the broad range of medical implications of homocysteine.
How to quickly recognize and treat your own specific kind of headache/migraine. This "Migraines and Headaches" is outstanding because of its diverse therapeutical approach and its practical attitude in dealing with this common aggravating affliction. A unique questionnaire helps to trace the real nature of the problems. Each migraine or headache has its own cause. The following causes of headaches/migraines are dealt with: vascular problems, a stressed system, hormonal imbalance, spine and neck afflictions, lowered resistance, infections, metabolic and digestive problems (including allergy), toxification, dental and scar disorders, electro stress, psychological factors and many others. Many suggestions are given as to the various treatments that might help in finding the cause of the headaches/migraine, such as: DIY-reflexology programmes, herbs, exercises in respiration, energy related exercises, relaxing techniques, healing, psychotherapeutic possibilities.The authors have joined their skills for many years, published several books, meditation cd's and articles
