Our findings of clear age-related advantages between age 8 and young adulthood in learning a new morphological skill do not support a simple notion of a restricted developmental time window or a 'critical period' of heightened plasticity in linguistic skill acquisition.
There was an absence of a clear age-related pattern for utilization of this service (only men 75-79 had statistically more visits than the comparison group of men aged 65-69).
The differential impact of stigma is less clear: age disparities are common throughout sub-Saharan Africa; 42 however, the recent increase in anti-sugar daddy campaigns may lead to greater stigmatisation of age-disparate relationships.
For the number of teeth, there is a clear age gradient, a social class gradient and the expected income effect.
However, in the cohorts that received their MenCC immunization after the tetanus booster at 9 years of age, a clear age-related increase and persistence of tetanus-specific antibodies was observed, similar to the MenC-specific antibody levels (Fig. 3).
While no gender-dependent differences were demonstrated for the Sr concentrations in the liver and kidney of the cats, clear age-related variations were found.
However, a clear ageing of the TB mare population from 1982-3 to 2002 was evident similar to our observations.
Using data set 3, demonstrating distinct age-related gene clustering (Supplementary Material, Fig. S2A), MCT8 is prominently ranked among the subset of genes with a clear age-dependent decrease in expression (Supplementary Material, Fig. S2B).
In animals of advanced age (30 months) clear age-related changes became apparent, in which the enlargement of the print area of the hindpaws was the most prominent one.
To examine the possible expression of TXNL6 in lens epithelial and lens fibers, whole human lenses (average age of clear lenses obtained was 63 years of age) were microdissected into epithelium and cortical fiber cells and RNA and protein prepared.
