These different specialties were chosen on the basis of differences in procedures and organization of work, connected with characteristics of tasks, patient contacts and cooperation with other disciplines.
In one instance, material once referred to four genera and seven species on the basis of differences in molar shape is now thought to represent differently aged individuals of a single species, Cardiatherium paranense.
Screening of differentially expressed genes (DEGs) was performed on the basis of differences in the IMF, TG and PLIP contents at different ages in each breed.
