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 and Objective: The 1,450-nm Smooth-beam™ Laser is a diode laser equipped with a cryogen cooling spray. Primary objectives were to evaluate the effects of this non-ablative laser on Apligraf® (bioengineered skin-substitute) and to document its use as a model for non-ablative procedures. We also measured the effects of laser fluence levels on collagen and elastin expression. Study Design/Materials and Methods: Three sheets of Apligraf® were used for this study. Each received six separate laser applications at 4J, 6J, 8J, 10J, 12J, and 14J. The sheets were then incubated with 10% CO at 37°C and samples were collected and analyzed 3 days later, using RT-PCR and immunofluorescent staining. Results: Collagen III expressions significantly increased in both mRNA and protein levels at approximately 12J. Conclusions: There appears to be a threshold effect where there is very little increased collagen III mRNA and protein expression until the laser fluence reaches around 12J. © 2005 Wiley-Liss, Inc.
