Perhaps you should try some spelling variations:
decrease lesion » decrease adhesion (Expand search), decrease asian (Expand search), decrease soon (Expand search)
lesion pattern » lesions pattern (Expand search), lesion patterns (Expand search), design pattern (Expand search)
decrease food » decreases food (Expand search), increase food (Expand search), decreases blood (Expand search)
food decrease » food decreases (Expand search), foods decreases (Expand search), flow decrease (Expand search)
decrease hiv » decrease in (Expand search), decrease their (Expand search), decreased high (Expand search)
hiv decrease » via decrease (Expand search), hiv increase (Expand search), will decrease (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 AND decrease hiv decrease ) OR ( decrease food decrease lesion pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease hiv decrease ) OR ( decrease food decrease lesion pattern ))*.
