It has been reported that the amount of D-aspartic acid in dentin is highly correlated with age. However, further studies are necessary to determine the details of this correlation. We quantitatively determined L- and D-aspartic acids in de...

Three potential errors in applying the Gompertz growth model are discussed: 1. Restriction of growth data to the subadult or juvenile phase; 2. Confusion of mean growth rate with (mean) maximum growth rate; 3. Improper application of the gr...
