Instructions for Authors continued

the title page of the manuscript. Material prepared on a word processor should be printed on a letter-quality printer. All manuscripts accepted for publication should be accompanied by a final version in electronic format. Cover Letter A cover letter must accompany all submitted manuscripts. The cover letter should provide the name, complete address, telephone number, and facsimile number of the corresponding author (and electronic mail address if available). Acknowledgment of receipt of manuscripts by the Editorial Office will be made via facsimile or e-mail only. Title Page The title page of the original copy of the manuscript must include the full name(s), highest academic title(s), and affiliation(s) of all authors. The full address and telephone/ facsimile numbers of the corresponding author should be clearly indicated separately. The two additional copies to be sent to the reviewer should include only the full title of the manuscript and should not include the authors’ names or affiliations nor identify the corresponding author. Similarly, the Materials and Methods section in the two additional copies submitted should not identify the institution(s) where the work was performed. This information, however, must be provided in the original copy submitted to the Editors and in the final version for publication. Abstract The abstract should be typed on a separate page and should not exceed 250 words. The abstract should be followed by a maximum of 6 key words for indexing purposes. Tables All tables must be numbered sequentially in the order of their citation in the text. Each table should be typed doublespaced on a separate sheet of paper and should be accompanied by a clear and specific title. Figures and Figure Legends All figures must be numbered sequentially in the text and accompanied by figure legends typed on a separate page. Legends should be brief and specific. The type of stain used should be indicated in the legend only if other than hematoxylin and eosin. Do not provide magnifications for histological preparations; the magnification may be cited in the corresponding figure legend as ‘‘scanning,’’ ‘‘medium power,’’ and ‘‘high power,’’ if needed. Original magnifications should be cited in the figure legends for electron micrographs. All illustrations should be submitted in triplicate. Only one set should be labeled with the first author’s name on the back and included in a separate enveloped marked ‘‘for publication’’; the two additional sets of illustrations should only include the figure number and short title of the paper. Indicate the top of the figure with an arrow on the back of the print. Original artwork (graphs, charts, line drawings, etc) should be submitted as glossy black & white prints. All illustrations should be unmounted and submitted as sets in separate envelopes. Color illustrations may be included at the author’s expense. Submit the original set of color illustrations as 2  2 Kodachromes and the additional two sets for the reviewers as color prints. Figures may be submitted in electronic format. Images should be provided in EPS or TIF format on Zip disk, CD, floppy, Jaz, or 3.5 MO. Graphics software such as Photoshop and Illustrator, not presentation software such as PowerPoint, CorelDraw, or Harvard Graphics, should be used to

create the art. Color images must be CMYK, at least 300 DPI, with a digital color proof, not a color laser print or color photography (this proof will be used at press for color reproduction). Gray scale images should be at least 300 DPI and accompanied by a proof. Combinations of gray scale and line art should be at least 1200 DPI and accompanied by a proof. Line art (black and white or color) should be at least 1200 DPI and accompanied by a proof. Please include hardware and software information, in addition to the file names. References Reference numbers in the text should follow numerical order and be enclosed in parentheses or superscripted. References are listed in the order in which they are referred in the text, not in alphabetical order; they must follow the style of the samples provided. Include all author names when there are three or fewer authors; for references that contain more than three authors, list only the first three and use et al. Personal communications and unpublished observations should be indicated in parentheses within the text but excluded from the reference list. Information from manuscripts submitted but not yet accepted should be cited in the text indicated in parentheses as ‘‘unpublished observations.’’ Authors are responsible for the bibliographic accuracy of all references.
