Perhaps you should try some spelling variations:
increases during » increase during (Expand search), increases brain (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease lethal » decrease fetal (Expand search), decrease renal (Expand search), decrease total (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)
lethal doses » lethal dose (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: "(( increases during decrease NOT decrease ) OR ( decrease toc decrease lethal doses ))~".
• Adding a wildcard symbol may retrieve word variants: (( increases during decrease NOT decrease ) OR ( decrease toc decrease lethal doses ))*.
