Dear waleed Fouad Abobatta ,

In addition to what is suggested by Anton Vrdoljak . For a bit more details why their name popped up, have a look at:

https://www.researchgate.net/post/Identification_of_yet_another_predatory_publisher it describes a so-called sting paper issue, proving that at least one of their journals do not perform (proper) peer review. Additional red flags are:

-According to: https://meddocsonline.org/about-us.html and the mentioned contact info: https://www.bizapedia.com/addresses/401-ryland-st-suite-200-a-reno-nv-89502.html seems to suggest that this is ‘just’ a virtual office for registration purposes in order to suggest American origin, question remains whether this is really true

-They charge 1500 USD which is ridiculously high for basically non indexed journals

-The same ‘address’ is used by several other ‘publishers’: https://opencorporates.com/companies/us_nv/E0545022010-6 YELLOWBIRD PUBLISHING LLC and https://www.federalpay.org/paycheck-protection-program/kipling-publishing-group-llc-reno-nv Kipling Publishing Group LLC http://en.nevadacorporates.com/1205565/ UNITED KING PUBLISHING, LL

-Checked a number of their journals that do not seem to attract a lot of submissions. Furthermore, I have reasons to believe that not all journals assign a DOI to the papers (although all have a prominent CrossRef logo)

All together I think this is one to avoid.

Best regards.
