Perhaps you should try some spelling variations:
increase lesions » pancreas lesions (Expand search), disease lesions (Expand search), increase long (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease baking » decrease walking (Expand search), decrease during (Expand search), decrease owing (Expand search)
baking process » making process (Expand search), aging process (Expand search), buying process (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not increase » and increase (Expand search), an increase (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 _ decrease baking process ) OR ( decrease NOT increase lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease _ decrease baking process ) OR ( decrease not increase lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease baking process ) OR ( decrease not increase lesions decrease ))*.
