Perhaps you should try some spelling variations:
"murine model" » "murine models"
"linear mode" » "linear model", "linear models", "bilinear model"
"line models" » "line model", "linear models", "murine models", "line modells", "lines modells", "online models"
"line mode" » "line model", "lines model", "online mode"

Try widening your search to All Fields.

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: (((("line mode") OR ("linear mode"))) OR ((("line models") OR ("murine model")))).
• Removing quotes may allow a broader search: (((( line mode ) or ( linear mode ))) or ((( line models ) or ( murine model )))).
• Adding a wildcard symbol may retrieve word variants: (((("line mode") or ("linear mode"))) or ((("line models") or ("murine model"))))*.
