Perhaps you should try some spelling variations:
their progenies » their properties (Expand search), their progeny (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
life decrease » life decreases (Expand search), life decreased (Expand search), life increase (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (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 life decrease their progenies ) OR ( decrease OR decrease toc decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease life decrease their progenies ) OR ( decrease or decrease toc decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease life decrease their progenies ) OR ( decrease or decrease toc decrease ))*.
