Four databases (CINAHL, EMBASE, PubMed and SPORTDiscus) were searched using various combinations of the keywords: "risk OR predisposition OR genetic* OR aetiology OR etiology OR overuse OR pathogenesis" AND "Achilles OR Achilles Tendon" AND "tendinopathy* OR tendinitis OR tendonitis OR tendinosis OR injury OR pain" AND "exercise OR physical activity OR sport* OR run*".
Molecular signatures of selection were searched using various statistical tests.
Eleven electronic literature databases were searched using key terms of various combinations and filter string terms.
Rather than using any of these programs or a combination of them as strict filters we generated a database containing all the results that could be browsed or searched using various criteria to extract particular gene families of interest.
Binding sites of the catalysts that recognize the targets have been searched by using various kinds of chemical libraries.
Drug-like ligands obtained from protein ligand complexes deposited in the Protein Databank were subjected to conformational searching using various force fields and solvation settings.
In addition, data obtained from the LC-MS/MS analyses were searched against various databases using Mascot and were alternatively interpreted de novo and searched against the same databases using MS BLAST [ 33].
Fortuitously discovered to begin with, TEs were then searched for using various methods, including transposon trapping, and are now mainly identified as repeated sequences with particular features within sequenced genomes, or through protein homology, with the help of various and numerous programs and databases.
This search was supplemented using various methods, including most related articles searching for each of the included studies in PubMed, searching articles that reference the included studies in Web of Science (also called forward citation searching), and scanning the reference lists of included studies and relevant reviews.
HydA1 rare codons were searched for in various organisms using a software that compares genes sequences from NCBI with the codon usage data from different genomes of Kazusa DNA Research Institute (Japan).
