Perhaps you should try some spelling variations:
experimentellen pharmacologic » experimentelle pharmakologie, experimental pharmacologic, experimental pharmacology
experimentellen dermatologie » experimenteller dermatologie, experimentelle teratologie, experimentelle rheumatologie
experimentelle gerontologie » experimentelle teratologie, experimentelle neuroonkologie, experimenteller dermatologie

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( handbook of experimentellen pharmakologie ) OR ((( handbook of experimentellen pharmacologic ) OR ((( handbook of experimentellen dermatologie ) OR ( handbook of experimentelle gerontologie )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( handbook of experimentellen pharmakologie ) or ((( handbook of experimentellen pharmacologic ) or ((( handbook of experimentellen dermatologie ) OR ( handbook of experimentelle gerontologie ))))))".
• Adding a wildcard symbol may retrieve word variants: (( handbook of experimentellen pharmakologie ) or ((( handbook of experimentellen pharmacologic ) or ((( handbook of experimentellen dermatologie ) OR ( handbook of experimentelle gerontologie ))))))*.
