For skin, samples of the same age clustered next to each other, indicating that age-specific transcript patterns are similar in both short- and longer-lived strains.
In skin, samples of the same age clustered better than those of the same strain, whereas in brain, samples of the same strain seemed to cluster better than age.
In the present study, 28 different signs were used to quantify aging, clustered into four clinical domains: wrinkles and skin texture, ptosis and sagging (tissues slackening), pigmentation disorders, and others.
Upon aging, clustering of Pd atoms within the Fe Mn solid solution occurs.
For all the women in the S-S and S-P groups, we analyzed on all age clusters the difference between apparent age, as estimated by a panel of 30 people, and real age.
After statistical testing, 169 seniors were assigned to the active ageing (AG) cluster and 69 to the inactive ageing (IG) cluster.
The genes repressed in both ages (Cluster F, Table 2) include proliferation related genes, which complement the genes induced in cells from both age groups.
Age was clustered into four groups: age 4-18 years (children), 19 39 years (young adults), 40 64 years (older adults), and 65 years and older (elderly).
Age was clustered into four groups: age 16 24 years, 25 44 years, 45 64 years, and 65 years and older.
Ages were clustered so that results would be comparable with the 2005 GBD study.
