Output should include the LipidX ID and the corresponding SwissLipids ID(s) and name(s) plus PubMed ID(s). 
This query first identifies SwissLipids identifiers for a given list of LipidX identifiers. It then retrieves the corresponding Isomeric subspecies that are linked to at least one publication, and the corresponding PMIDs.
