It is not necessary to repeat information presented in the Methods and Results sections. It is particularly important in the Discussion section to use subheadings so that the reader can follow the authors' train of thought. Manuscripts of any type that advance a particular instrument, device, or methodology must contain a statement indicating whether any author has a financial interest in the subject under discussion. Exercise care in choosing illustrations for publication. All black and white figures approved by the Editorial Board will be published free of charge.
Authors are responsible for the costs of reproducing color figures.
The type size of any lettering on the art should not be less than 9 points. Different patterns are generally preferred to shading. The back of each figure must be clearly labeled in pencil, including the correct orientation, and consecutively numbered in relation to their appearance in text. Letters and arrows should be applied directly to the figure. Electron micrographs must contain measurement bars to indicate their magnification.
