After I compile my PNAS journal document, a part of the references should be in helvetica-boldoblique style. However, it is printed simple bold (helvetica-bold). When I change the font settings in the style and class file from boldoblique to oblique, it text will be italic but not bold anymore.
I have tried this solution, but it is not working: Latex font error ... I can't find 'hv'
