International Journal of Diabetes Research

International Journal of Diabetes Research publishes reports of experimental and clinical research on diabetes mellitus and metabolism. Original contributions on morphological, biochemical, physiological and clinical aspects of research on diabetes and metabolism are welcome. The role of the journal is to provide a venue for dissemination of knowledge and discussion of topics related to diabetes clinical research and patient care.
