Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Digestion of nuclei of the cerebral hemisphere of young (18-20 week) and old (90-97 week) rats by DNase I shows that the rate and extent of digestion is lower in the old. Time course analysis of the DNA fragments produced by DNase I by polyacrylamide gel electrophoresis shows that more of the lower base pair fragments are produced in the young. Also, the rate of production of these fragments is higher in the young than in the old. Assay of template-engaged RNA polymerase II (α-amanitin sensitive) shows that in the old it is only about 50% of that of the young. Addition of exogenous eukaryotic (wheat germ) RNA polymerase II is not able to restore transcription of the chromatin in the old to the level of the young. These data show that chromatin undergoes increasing condensation as a function of age, resulting in decreased transcriptional activity in old age. © 1985 Dr W. Junk Publishers.
