Several individuals made important contributions to this book. I thank Dr. JoAnna Perry, who edited, contributed to several chapters, and obtained permissions for reproducing data; Sylvia Wrobel, who contributed to the first three chapters; Jordan Licata, who compiled the glossary; and Janie Langford, who helped obtain permissions.

I also thank others who contributed to the book in various ways: Jo Tunstall, Pat Harris, Brenda Lloyd, Susan Marshall, Dr. David Gorelick, Dr. Eliot Gardner, Dr. Roy Wise, Dr. Leonard Howell, Dr. Heather Kimmel, and Dr. Darryl Neill.

The editors, Russ Hall and Kirk Jensen, provided much needed advice and assistance every step of the way.

I am very grateful for my mentors, colleagues, and trainees, who, for more than four decades helped develop my skills and knowledge so that this book was possible. Support from the National Institutes of Health (NIH) was essential.
