Perhaps you should try some spelling variations:
within progenies » sibling progenies (Expand search), in progenies (Expand search), their progenies (Expand search)
decrease within » decrease with (Expand search), decreases with (Expand search), disease within (Expand search)
decrease limb » decrease lipid (Expand search), decrease liver (Expand search), decrease in (Expand search)
limb decrease » will decrease (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), and decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease limb decrease within progenies ) OR ( decrease rate decrease to decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease limb decrease within progenies ) OR ( decrease rate decrease to decrease ))*.
