DOI number (Digital Object Identifier)
We are not affiliated with and didn’t subscribe to https://www.doi.org for obtaining DOI numbers.
Reason

DOI numbers are attributed to manuscripts that are only published in a digital form and thus online. As we have a physical magazine in which we publish the articles in March, June, September and December, and we publish the articles on this website also, our articles can’t be considered as digital only.
However, you can always communicate your PMID number (available in PubMed) to whom is requesting your (inexistant) DOI number.
