Metric Options: CountsSelecting 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
A new method was modified and evaluated as a simple, sensitive and quantitative procedure for measuring metallothionein (MT) in tissues. Heat denatured cytosolic fractions of tissue homogenates were incubated with 109 Cd and bovine hemoglobin was added to scavenge Cd not bound to MT. The hemoglobin and excess Cd were separated from the 109 Cd-MT by heating. The Cd remaining in the supernatant was a quantitative measure of the MT present. Analysis of Sephadex G-75 and DEAE-ion exchange fractions of liver supernatants from Cd and Zn-treated rats indicated that the assay is specific for MT. Levels of MT in six rat tissues were quantitated in untreated and Cd-treated rats and were consistent with previous studies on tissue levels of MT. Because of its speed and sensitivity, this assay may be useful for measuring MT in large studies where time and expense are limiting factors.
