It presents chromatograms with exact elution programs enabling visual analysis and compares the advantages-disadvantages of various chromatographic techniques. In accordance with the chronological order of the development of chromatographic methods, different techniques are discussed: The possibilities of gas chromatography (GC), followed by those of the high performance liquid chromatography (HPLC) and the most recent techniques capillary electrophoresis (CE), capillary, electrochromatography (CEC). The characteristics of the given chromatographic procedure, relating to the topic in question, are classified according to the preliminary preparation/derivatization process(es), which means the simple methods, suitable for the analysis of the selected compound(s) in natural form, are followed by various derivatization proposals.

Book Description
Trace Amines and Neurological Disorders: Potential Mechanisms and Risk Factors explores trace amines which, under normal conditions, are present in the mammalian brain and peripheral nervous tissues at very low (nanomolar) concentrations. However, in a diverse array of human pathologies ranging from substance abuse, depression, attention deficit hyperactivity disorder, eating disorders, schizophrenia, and other neurological and neuropsychiatric diseases, the levels of trace amines are unusually high with an imbalance in their functions. Furthermore, the rapid turnover of trace amines is evidenced by their dramatic increases following treatment with monoamine oxidase inhibitors (MAOI) or deletion of the MAO genes. This suggests that the concentration of trace amines may be considerably higher at neuronal synapses than predicted by steady-state measures, implicating some pathophysiological role. Therefore, understanding molecular mechanisms and developing selective agonists and antagonists for trace amine-associated receptors (TAARs) has become a good approach for treating these diseases. Although the effects of trace amines at low physiological concentrations in mammalian species have been difficult to demonstrate, they may serve to maintain the neuronal activity of other monoamine neurotransmitters by possessing postsynaptic modulatory effects, particularly dopamine and serotonin, within defined physiological limits. Such an effect of trace amines makes them ideal candidates for the development of novel therapeutics for a wide range of human disorders. This book presents up-to-date, cutting-edge, and comprehensive information on the link between trace amines and neurological disorders. Focuses on recent findings on trace amines, providing insights into the functional significance, molecular mechanisms, and biological relevance of TAARS in neurological disorders Edited work with chapters authored by leaders in the field from around the globe, the broadest, most expert coverage available Provides cutting-edge research on trace amines-mediated signaling in vertebrate model systems

Book Description
Amines and Schizophrenia is a collection of articles that survey and discuss the biochemical basis present, if any, in schizophrenia, focusing on the role of certain amines. The book discusses certain hypotheses dealing with the field of bio-chemistry as the basis for diseases such as schizophrenia, manic-depressive psychosis, and related diseases. Discussions start with the properties of mescaline, because the psychotic effect of the drug has some aspects similar to that of a schizophrenic syndrome. One paper examines the presence of certain amines, such as norepinephrine, dopamine, and serotonin in the brain, including their role in the synaptic transmission of nerve impulses in the central nervous system. Other papers review the role of derangements of tryptophan metabolism in psychotic behavior; the metabolic interrelationships of tryptophan and methionine in mental illness; and the results obtained with psychomimetic and non-psychomimetic congeners of three classes of indoleamines including LSD. The book gives more details on the actions of various biological amines on single neurons in the limbic system of the brain. The text also evaluates the use of hallucinogenic drugs in considering their heuristic value in the study of the biochemical basis of mental function. The selection will prove relevant for psychologists, psychiatrists, drug researchers, pharmacologists, and chemical laboratory workers and technicians.

Book Description
A precise analysis of biogenic amines is important as an indicator of food freshness or spoilage that can cause serious toxicity. This book provides comprehensive background information on biogenic amines and their occurrence in various foods and drinks such as fermented and non-fermented sausages and fish products, cheeses, vegetables and beverages, e.g. beer, cider and wine. It gives a detailed description of both the established analytical methods and the emerging technologies for the analysis of them. As the first book on the detection of biogenic amines in all types of food, it provides help to get a better understanding of the risks associated with biogenic amines and how to avoid them. It serves as an excellent and up-to-date reference for food scientists, food chemists and food safety professionals.

Book Description
Biogenic amines have been known for some time. These compounds are found in varying concentrations in a wide range of foods (fish, cheese, meat, wine, beer, vegetables, etc.) and their formations are influenced by different factors associated to those foods (composition, additives, ingredients, storage, microorganism, packaging, handing, conservation, etc.). The intake of foods containing high concentrations of biogenic amines can present a health hazard. Additionally, they have been used to establish indexes in various foods in order to signal the degree of freshness and/or deterioration of food. Nowadays, there has been an increase in the number of food poisoning episodes in consumers associated with the presence of these biogenic amines, mainly associated with histamines. Food safety is one of the main concerns of the consumer and safety agencies of different countries (EFSA, FDA, FSCJ, etc.), which have, as one of their main objectives, to control these biogenic amines, principally histamine, to assure a high level of food safety. Therefore, it is necessary to deepen our understanding of the formation, monitoring and reduction of biogenic amines during the development, processing and storage of food, even the effect of biogenic amines in consumers after digestion of foods with different levels of these compounds. With this aim, we are preparing a Special Issue on the topic of "Biogenic Amines in Food Safety", and we invite researchers to contribute original and unpublished research articles and reviews articles that involve studies of biogenic amines in food, which can provide an update to our knowledge of these compounds and their impacts on food quality and food safety.

Book Description
Biogenic amines (BA) are sources of nitrogen and precursors for synthesis of hormones, alkaloids, nucleic acids and proteins, occurring in all organisms. Under normal condition in humans the consumption of food or beverages containing these compounds have not toxic effects because they are rapidly detoxified by the activity of the amine oxidizing enzymes, monoamine (MAO) and diamine oxidases (DAO). However in presence of high BA content, in allergic individuals or if MAO inhibitors are applied the detoxification system is not capable of metabolizing dietary intake of BA. This fact can induce toxicological risks and health troubles, but the European Union established regulation for just only histamine levels in fish and fishery products. The presence of BA in foods is due to the enzymatic decarboxylation of free amino acids by microorganisms that possess this activity. Many foods such as meat products, cheeses, fishes, fermented products and beverages could contain high levels of these compounds. Determination of BA rates in food are important as indicators of the degree of freshness or spoilage other then from the point of view of their toxicology. The content of the E-Book deals the presence of BA in some fermented and non fermented foods and the measures to control their content.
