The chemical symbols look inconsistent, nuclear ancient Ca2+ upright,
Ca2+ homeostasis oblique. Do you have special reasons to avoid mhchem,
which comes preloaded with LyX? If you use the mhchem-macro for
chemicals such as \ce{Ca^2+} in LyX math mode, then you get a
consistent typesetting and a preview.
