I speak Spanish and have examined parts of the web site.  If you go to
the following page you can click on "ingles" at the bottom of the page
and see the journal list in English.

http://www.imbiomed.com

The URL you have takes you to the journal index.  I looked under
"Reconocimientos" where I found  "Que es Imbiomed?"  (What is Imbiomed?)
Here it tells you that there is free access for health care
professionals, but you do have to register.

Hope this helps.
