Perhaps you should try some spelling variations:
decrease flooding » decrease following (Expand search), decrease lodging (Expand search), decrease food (Expand search)
flooding process » flooding processes (Expand search), loading process (Expand search), folding process (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
further decrease » further increase (Expand search), faster decrease (Expand search), the decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
lesions case » lesion case (Expand search), lesions caused (Expand search), lesions based (Expand search)
case further » scale further (Expand search), coast further (Expand search), can further (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 NOT decrease flooding process ) OR ( decrease lesions case further decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease flooding process ) OR ( decrease lesions case further decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease flooding process ) OR ( decrease lesions case further decrease ))*.
