On behalf of the American Physician Scientists Association, it is my pleasure to invite you to the 4th Annual Meeting of the American Physician Scientists Association which will be held in conjunction with the American Society for Clinical Investigation and the Association of American Physicians. This promises to be yet another stellar meeting as this will be the ASCI's centennial meeting. So save the date!!! April 25-27, 2008. Information will be available on the APSA Meetings Page (http://www.physicianscientists.org/Meetings.html) as it becomes available.
