Dear Nature Index Support Team,I am writing to seek your assistance regarding a potential metadata distribution issue for one of our recently published articles.
The article in question is:
Title: Fine Particulate Matter (PM2.5) and the Blood-Testis Barrier: An in Vivo and in Vitro Mechanistic Study.
Authors: Shaoakai Zheng, Nannan Zhao, et al.
DOI:10.1289/EHP14447
Online Publication Date: April 15, 2025
We have confirmed that the article（It is a primary research article）is live on the EHP website and has been indexed by theDimensions database. However, it has not yet been picked up by the Nature Index, which sources its data from Dimensions.This suggests there might be a delay or an issue in the metadata flow from EHP to the broader indexing services. Could you kindlyverify from your end that the metadata for this article has been successfully and completely distributed to all relevant aggregators, including Dimensions?Your help in investigating this matter would be greatly appreciated, as the inclusion in the Nature Index is important for our institution's assessment.Thank you for your time and support.
Sincerely,
Lianglin Qiu
