The journal provides the reader with a thorough description of theoretical and applied aspects of trace elements in medicine and biology and is devoted to the advancement of scientific knowledge about trace elements and trace element species. Trace elements play essential roles in the maintenance of physiological processes. During the last decades there has been an important progress in scientific investigation about the function and binding of trace elements. The Journal of Trace Elements in Medicine and Biology focuses on the description and dissemination of scientific results concerning the biological role and action of trace elements including different fields such as analytical methods, biochemistry, patho-biochemistry of metabolic processes, molecular biology, nutrition, toxicology, environmental toxicology, epidemiology, clinical applications in diagnosis, therapy, food chain and veterinary medicine. Progress in the knowledge of the biological role of trace elements depends, however, on advances in trace elements chemistry. The Journal of Trace Elements in Medicine and Biology publishes high quality, evidence-based research and includes only those studies that base their results on proven analytical methods and in which the quality assurance regarding the execution of experiments and achievement of results is guaranteed.
