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
Aims: To screen the preeclampsia-related protein by proteomics. Methods: Proteomics was performed to identify differential protein expression profiles between normal full-term pregnancy, early-onset severe preeclampsia (ES-PE) or late-onset severe preeclampsia (LS-PE; n = 10 per group). Real-time quantitative PCR and immunohistochemistry were conducted to confirm the expression of α -antitrypsin (α -AT) in the decidual tissues of different subjects. ELISA was employed to detect the α -AT content in the peripheral blood of 90 women (n = 30 per group). Results: We successfully constructed two-dimensional electrophoresis maps of decidual tissues, and a total of 20 differentially expressed proteins were identified. The α -AT expression was different among the three groups. The normal full-term pregnancy women expressed the most α -AT, and the LS-PE women expressed the least amount of α -AT. The difference in the α -AT expression was consistent with the proteomics data. The peripheral α -AT content was the highest in the normal full-term pregnancy group (1.85 ± 0.15 g/l), moderate in the ES-PE group (0.77 ± 0.14 g/l) and lowest in the LS-PE group (0.42 ± 0.07 g/l; p < 0.05). Conclusion: Using 2D PAGE, we identified twenty proteins with significantly altered expression in PE. These differentially expressed proteins include prevention protein, in which α -AT is downregulated in PE. © 2012 S. Karger AG, Basel.
