Perhaps you should try some spelling variations:
"i large decrease" » "i marked decrease" (Expand Search), "i large increases" (Expand Search), "i large degree" (Expand Search), "_ large decrease" (Expand Search), "via large decrease" (Expand Search), "i larvae decrease" (Expand Search)
"a large decrease" » "a marked decrease" (Expand Search), "a large increases" (Expand Search), "a large degree" (Expand Search), "_ large decrease" (Expand Search)
"wt levels increased" » "atp levels increased" (Expand Search), "alt levels increased" (Expand Search), "_ levels increased" (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: "((\"wt levels increased\") OR (((\"i large decrease\") OR (\"a large decrease\"))))~".
• Removing quotes may allow a broader search: (( wt levels increased ) OR ((( i large decrease ) OR ( a large decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("wt levels increased") OR ((("i large decrease") OR ("a large decrease"))))*.
