Perhaps you should try some spelling variations:
decrease their » increase their (Expand search), decreases the (Expand search)
their projects » the projects (Expand search), their products (Expand search), thematic projects (Expand search)
treg decrease » urea decrease (Expand search), drugs decrease (Expand search), break decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and 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 the decrease treg decrease ) OR ( decrease AND decrease their projects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrease treg decrease ) OR ( decrease and decrease their projects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease treg decrease ) OR ( decrease and decrease their projects ))*.
