Maturation was defined as the visualization of a polar body at the end of the incubation period.
The osteoblast maturation is defined by the biosynthesis and organization of extracellular matrix proteins, such as osteocalcin, bone sialoprotein and osteonectin [ 23].
Meiotic maturation is defined by the transition to metaphase I, signified by nuclear envelope breakdown, rearrangement of the cortical cytoskeleton, and meiotic spindle assembly.
Oocyte meiotic maturation is defined by the transition between diakinesis and metaphase of meiosis I and is accompanied by nuclear envelope breakdown, rearrangement of the cortical cytoskeleton, and meiotic spindle assembly (Masui and Clarke 1979).
Given our survival observations (see results), 'old females' were defined as 30 days post maturation and 'old males' as 10 12 days post maturation.
Early meristems were defined as those containing only two mature open flowers, while late meristems were defined as those that had experienced the maturation of twenty flowers.
Egg quality is acquired during oocyte growth and maturation and can be defined as the ability of the egg to be fertilized and subsequently develop into a normal embryo.
The mechanism of decline in the catalytic activity of intestinal lactase during neonatal maturation has not been defined, but a shift in the lactase subunit synthesis from an active 130-kDa subunit to an inactive 100-kDa species has now been noted in the adult rat (Quan, R., Santiago, N. A., Tsuboi, K. K., and Gray, G. M. (1990) J. Biol.
In those infants with a clear maturation stage could be defined using the classical definition, we examined the possibility that trends in the data as well as the quantization of the time series due to the resolution of the temperature probe would affect the DFA calculation.
However, several of the mechanisms required for full antibody maturation have yet to be defined.
