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 modified and derived ethanol injection (MDEI) process was developed to produce liposomes. The aim of the present study was to more efficiently control the vesicle diameter than with the conventional ethanol injection method. A hot ethanolic solution of lipids (60°C) was injected into a hot aqueous buffer (70°C). Then, ethanol was removed by rotary evaporation under reduced pressure. The size of the liposomes could be controlled by the ratio of ethanol to hydroalcoholic solution before evaporation. The concentration of lipids, the charge of lipids, and the type of aqueous phase had little effect on the vesicle diameter when the process involved a ratio of 33% (v/v) ethanol. In addition, it was possible to obtain lipid concentrations 10- to 30-fold higher that the conventional ethanol injection method. The encapsulation of a hydrophilic compound was feasible with this MDEI process. The observation by cryogenic transmission electron microscopy revealed that these liposomes were predominantly unilamellar at a ratio as high as 33 or 50% (v/v) ethanol. Thus, the results showed that MDEI is an appropriate alternative for the manufacture of liposomes with respect to the ethanol injection process. © 2013 Informa Healthcare USA, Inc.
