Abstract

The repeat sequence primer-PCR technique was used to determine DNA polymorphism of the aphid Aphis gossypii (Glover) collected from 8 different localites in China. Three primers were selected and used for similarity index (SI) and cluster analysis based on the data of Nei's genetic distance (D). We found that the populations in the north and northwest of China was linked before they were joined by those in southern China. A proposed explanation emphasizes the populations in the north and northwest of China were located near — 4 °C isotherm or lower in January with less than 200 frost-free days per year, whereas populations in southern China were located near 0 °C isotherm or higher with more than 300 frost - free days per year. So it may be the over-winter host plants instead of the geographic distance or gene flow, exert pronounced influence on the geographic population differentiation of A. gossypii. Species on different over-winter host plants may directly lead to the genetic differentiation of their summer offsprings.

Abstract

Purpose: Literature reports of adverse drug events can be replicated across multiple companies, resulting in extreme duplication (defined as a majority of reports being duplicates) in the FDA Adverse Event Reporting System (FAERS) database because they can escape legacy duplicate detection algorithms routinely deployed on that data source. Literature reference field, added to in 2014, could potentially be utilized to identify replicated reports. FAERS does not enforce adherence to the Vancouver referencing convention, thus the same article may be referenced differently leading to duplication. The objective of this analysis is to determine if variations of the same literature references observed in FAERS can be resolved with text normalization and fuzzy string matching., Methods: We normalized the literature references recorded in the FAERS database through the first quarter of 2021 with a rule-based algorithm so that they better conform to the Vancouver convention. Levenshtein distance was then utilized to merge sufficiently similar normalized literature references together., Results: Normalization of literature references increases the percentage that can be parsed into author, title, and journal from 61.74% to 93.93%. We observe that about 98% of pairs within groups do have a Levenshtein similarity of the title above the threshold. The extreme duplication ranged from 66% to 87% with a median of 72% of reports being duplicates and often involved addictovigilance scenarios., Conclusions: We have shown that these normalized references can be merged via fuzzy string matching to improve enumeration of all the individual case safety reports that refer to the same article. Inclusion of the PubMed ID and adherence to the Vancouver convention could facilitate identification of duplicates in the FAERS dataset. Awareness of this phenomenon may improve disproportionality analysis, especially in areas such as addictovigilance., (© 2022 John Wiley & Sons Ltd.)
