It can be used when discussing variations or stages in the aging process, often in contexts related to biology, health, or social studies.
Example: "The study examined the effects of exercise on cognitive function at different levels of aging."
Alternatives: "across various stages of aging" or "at various ages of development."
Current aging research in China may need to collaborate with researchers in other countries to integrate the approaches of molecular imaging, stem cell biology, molecular genetics and genomics, molecular pathology, histology and embryology, systematic biology, bioinformatics, and clinical medicine to conduct research at different levels of aging and related diseases.
To examine the effect of interaction between age, ER status, and iTIL, we built multivariate Cox regression models for iTILs at different levels of age and ER status.
The objective of this study was to predict the E* dynamic moduli of the actual field mixtures placed in Arizona using more than 25 years of data at two different levels of aging: original and RTFO aged conditions.
The transcriptional association between CR and aging varied at different levels of analysis.
This simplification is reasonable since the incubation period for influenza is typically very short, e.g., 1.48 days in [ 21]. (2) Influenza vaccine is efficacious in preventing influenza infection and effective against influenza-like illness, albeit at different levels of efficacy and effectiveness for different age groups [ 8, 9].
Unfortunately, no manual exists to guide the preparations of nations at different levels of development or stages of the demographic ageing transition, and governments have to navigate without adequate maps or GPS systems.
The coefficients and R-squared shown in the table are the results of different regressions, each of them including as an independent variable the lagged employment rate defined at different levels of aggregation, i.e. skill 1 (defined by age and education) and skill 2 (defined by age).
Biological aging is a universal phenomenon occurring at different levels of organization including cellular level.
Based on the adjusted model, we calculated the differences in BMD for the average woman with respect to age and weight at different levels of exposure.
According to Balshaw, we are entering "the age of systems biology," with a growing ability to integrate data at different levels of organization and increasing levels of complexity.
