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
The aim of this study was to investigate the influence of different cyclodextrins (CyD) on physical characteristics of inhalation dry powders. The particle size was characterised by Aerosizer LD and aerodynamic behaviour of inhaled complexes assessed by twin-stage liquid impinger. The in vitro release profile of the powders was studied through Franz cell modified method. Produced particles showed a suitable size for pulmonary delivery, ranging between 1 and 5 lm. The nature of the CyD affected the powders performance on reaching the lower compartment ("Lungs"), mainly by the altering their aerodynamic properties, which is reflected on the different percentages of their emitted respirable fractions. HP-γ-CyD: fluticasone propionate complex showed a fast release of corticosteroid while γ-CyD had a constant release throughout time. The best characteristics for pulmonary delivery were obtained with acetyl-γ-CyD: fluticasone propionate complex.
