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
In Drosophila, heat shock (HS) during the pupal stage chronically hinders adult locomotor performance by disrupting wing development and cellular and/or tissue-level mechanisms that support walking and flight. Furthermore, heat pretreatment (PT) protects locomotor function against these disruptions. HS flies with abnormal wings were less able to alter trajectory in free fall relative to control, PT-only, and PT + HS wild-type flies. This deficit was less severe but still present in HS-only flies with wild-type wings. Transgenic increases in the copies of genes encoding the major inducible heat-shock protein of Drosophila melanogaster, Hsp70, also protected walking ability from disruption due to pupal HS. Walking velocity did not differ between excision (five natural hsp70 copies) and extracopy (five natural and six transgenic hsp70 copies) flies in the control, PT, and PT + HS groups, nor did velocity vary among these thermal treatment groups. HS dramatically reduced walking velocity, however, but this effect occurred primarily in the excision flies. These results suggest that Hsp70 and other mechanisms protect against heat-induced locomotor impairment.
