Wilfred Stein is the author of three previous books on membrane transport, the first appearing almost fifty years ago. He has edited numerous books and written some 180 papers on various aspects of membrane transport and especially transport kinetics. These papers, especially those written together with his colleague William Lieb, defined many of the concepts used today in discussing movement across cell membranes. More recently he has turned to the study of the kinetics of drugs used in cancer therapy and in the treatment of malaria. He has taught biochemistry, biophysics and physiology at the University of Manchester and the Hebrew University of Jerusalem and also at the Weizmann Institute in Israel. He is currently Emeritus Professor of Biophysics at the Hebrew University. He is married to a librarian and has four children and nine grandchildren. Thomas Litman works as a senior research scientist at LEO Pharma, where he is responsible for implementing bioinformatics in translational research. He has taught biophysics and transport physiology at the University of Copenhagen since 1994 and is the author of some 70 papers, most of which focus on multidrug resistance and functional characterization of drug transporters, such as P-glycoprotein. In particular the papers on transport kinetics of anticancer drugs, written together with his mentor, Professor Wilfred Stein, have been recognized as exemplary in the field. He completed his post-doctoral work at The National Cancer Institute, NIH 1997-9, where he played a key role in the identification and characterization of a new transporter, ABCG2 (MXR), involved in multidrug resistance. In 2002 he was appointed as Weimann associate research professor, and 2003-6 he was responsible for the master’s program in medical bioinformatics at the Bioinformatics Centre, University of Copenhagen. His interests range from basic and translational research to information technology and applied bioinformatics, including confocal microscopy, microarray analysis, noncoding RNA, proteomics, next-generation sequencing, and molecular modeling.

"...an excellent resource on the current understanding of channels, carriers, and pumps as well as transport processes and their important roles in health and disease. Score: 91 = 4 Stars" --Doody'sPraise for the previous edition:"It has become the "Bible" for my lab" --Tony Carruthers, Dean, Graduate School of Biomedical Sciences, UMass Medical School"The strength of this book is the way in which rigorous yet lucid expositions of the theoretical basis of various types of transport are integrated with illuminating discussions of experimental results. [This book] will continue to be rewarding reading when many symposium reports have become outdated, and it is warmly welcomed and recommended." --D.K. Apps, FEBS LETTERS, August 1991"With so much diversity in biology it is exhilarating to read Stein’s attempt at synthesis. More of this is needed . . . Stein’s book should earn a place of its own, for it does something that few others attempt: it puts channels, carriers, and pumps under one roof . . . the book’s greatest value: its potential for catalytic action on sometimes disparate fields." --Louis J. DeFelice, California Institute of Technology, CELL, August 1991
