Entire Blog Switched to Italics

Ok, I have searched the forums and tried the various suggested fixes (searched for open or <i> tags, as well as checking the box to correct invalidly nested XHTML automatically) and my blog is still showing in all italics, including the sidebar and navigation bar. It seems to be something amiss with one of my three most recent posts, as I didn’t have this problem before then. Can anyone take a look at my site code and see what I am missing? thanks!
