Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
and professions » and profession (Expand search), and professionals (Expand search), and professional (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease akt » decrease at (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decreases » decreased (Expand search)

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: (( decrease lesions decrease AND professions ) OR ( decrease akt decrease AND decreases ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease and professions ) OR ( decrease akt decrease and decreases ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease and professions ) OR ( decrease akt decrease and decreases ))*.
