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
Background & Objective: Doxorubicin as an effective chemotherapeutic agent is frequently used in various cancers. Nowadays, the application of doxorubicin is limited due to its cardiotoxic effects. The important mechanism which is involved in the cardiac injury of doxorubicin is the generation of reactive oxygen species; therefore antioxidant compounds may reduce cardiotoxicity. In the present study, we evaluated the protective effects of Portulaca oleracea extract against doxorubicin-induced damage in cardiomyocytes cell line H9c2. Materials & Methods: The H9c2 cells were pre-treated for 2h with different concentrations of extract (12-400µg/ml) or resveratrol (50µM, positive control), and then doxorubicin was added for 24h. Afterward, the cell viability, and parameters of oxidative stress including lipid peroxidation and reactive oxygen species (ROS) generation, and also apoptosis rate, were measured. Results: The results revealed that doxorubicin extremely decreased cell viability via increasing malondialdehyde, ROS, and apoptotic cells. The extract could reverse doxorubicin-induced cardiotoxicity through anti-oxidant activity. Conclusion: In conclusion, we witnessed that P. oleracea has protective effect against doxorubicin-caused cardiomyocytes damage.
