The phrase "age identical" is not a standard expression in written English and may cause confusion.
It could be used in contexts discussing individuals or entities that share the same age, but it is not commonly used.
Example: "The twins are age identical, making it difficult to tell them apart."
Alternatives: "same age" or "age-matched".
In order to determine the potential impact of infant responses at birth on the subsequent immunogenicity of delayed BCG vaccination at 6 weeks of age, identical assays were repeated in infants at 16 weeks of age.
This type of inter-unit variability study would have required both studies to use absolute duplicates of the same metabolic analysis systems (identical age, identical maintenance, identical volume and gas calibrations, and identical testing conditions).
In this proof-of-concept study, plasma from seven Trisomy 21 pregnancies and seven appropriately matched controls (similar maternal age, identical gestational week and fetal gender) was selected (Table 1).
To obtain a final concentration at 55 years of age identical to the one in the first scenario, the daily exposure levels were optimized to the following levels: 18.7 ng/kg/day for PCB-153, 13.8 ng/kg/day for PCB-180, and 11.6 ng/kg/day for HCB.
The main difference between these two approaches was that in the age-based, group classification was based on how fast or slow the children grow as their age was identical or constrained to be identical.
The subset of women we excluded was comparable to the study population; for example, their mean age was identical (74.3 years) and average BMI was very similar (28.8 vs. 29.2 kg/m).
In whole-rock isochron methods that make use of the rubidium-strontium or samarium-neodymium decay schemes, a series of rocks or minerals are chosen that can be assumed to have the same age and identical abundances of their initial isotopic ratios.
BALB/c corneas appeared larger overall compared to C57BL6 corneas; measurements of the overall mass of the enucleated eyes and diameters of the flat-mounted corneas confirmed that C57BL6 eyes and corneas were 6.8%and4.4%4% smaller respectively than those of BALB/c mice even though the masses of the two mouse strains at 8 weeks of age were identical.
For each test age, three identical replicate samples were prepared.
Variations in illumination, expression, gender, and age of identical twins' faces were also considered in this study.
Fourteen healthy, untrained young males (mean ± SD: 17.9 ± 0.7 yrs of age) performed identical maximal cycle tests in the morning (08 00-11 00 h) and late afternoon (16:00-19:00 h) in random order.
