**Meet the editors**

György M. Nagy, MD, PhD, DSc graduated from the Medical University in Pécs in 1974. He started his work at the Semmelweis University in 1974 at the 2nd Department of Anatomy led by Prof. Béla Halász. He obtained his PhD in Neuroendocrinology in 1992 and his Doctor of Science Degree in 1995. He worked in Birmingham (University of Alabama at Birmingham,

USA) as a Research Fellow from 1984 to 1987 in the laboratory of Jimmy D. Neill. He also spent two years (from 1989 till 1991) as a visiting professor in Charleston, SC at the Medical University of South Carolina, USA, in the laboratory of Steve L. Frawley and one year (between 1997-1998) at the Florida State University, Tallahassee, FL, USA in Marc E. Freeman's laboratory. At present, he is a Professor of The Ross University, Department of Anatomy, Commonwealth of Dominica. His main interests are the hypothalamic regulation of pituitary prolactin secretion and the molecular aspects of the function of mammotrope cells. The title of his best cited article is "Prolactin: Structure, function and regulation of secretion", written by Freeman ME, Kanyicska B, Lerant A, and Nagy GM (Physiological Reviews 80: 1523-1631, 2000)

Bela Ernest Toth Dipl. Eng, MD, PhD started his education with School of Engineering, (Dipl. Eng), graduated as a Medical Doctor (MD), and completed PhD in Neuroscience. He worked as a lecturer for graduate and postgraduate education at Medical School and also at Faculties of Bioengineering and Healthcare Sciences. His scientific background is based on university appoint-

ments and academic collaborations (Semmelweis University Budapest, Neuroendocrine Research Group Hungarian Academy of Sciences, Rudolph Magnus Institute of Pharmacology, University of Utrecht; Dept. of Molecular and Cell Biology Penn State University, USA; University of Veterinary Sciences, Hungary). Dr. Toth's research interest on circadian rhythms of PRL secretion started during the university years. He later continued to focus on biology of nutrition, development and regulation of immune cell response, and function of DA in neuroendocrine regulation. Lately, his interests are involving pre-clinical research. Dr. Toth continues his work as an expert in clinical trials for pharmaceutical drug development.
