RT Journal T1 Cold spring harbor symposia on quantitative biology..volume xiii: Biological applications of tracer elements JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1949 FD October 22 VO 141 IS 8 SP 570 OP 570 DO 10.1001/jama.1949.02910080070043 UL http://dx.doi.org/10.1001/jama.1949.02910080070043 AB Each of the previous symposiums has dealt with a single, though broad, problem in the borderline areas of biology, physics, chemistry and mathematics. The present symposium differs in that it centers on a method which is applicable to many problems. The primary emphasis is on the results obtained in biologic experimentation, rather than on the questions of production of tracer compounds or of the methods applied in their use.This volume contains twenty-five contributions, including studies on lipids, radioisotopes, purine metabolism and biosynthesis of porphyrins. The authors have contributed original knowledge and speak with authority on their respective fields. However, this is obviously not a book for the average general practitioner or internist. It is a valuable reference work for the physiologist, biochemist and pharmacologist and for the physician who wishes to use tracer elements in the diagnosis or treatment of disease.
