Abstracts and Key Words
An abstract not exceeding 250 words structured under the following section titles: Objective, Material and Methods, Results, Conclusions. Use only standard abbreviations. Enter some key words (not more than 10) in alphabetic order below the Abstract. Use terms from the Medical Subject Headings list from Index Medicus. Give the name, current address, fax number and e-mail address of the author(s) to whom correspondence, proofs and offprints are to be addressed.

Acknowledgements
Acknowledge only persons who have made a substantive contribution to the study. Authors are responsible for obtaining written permission from everyone acknowledged by name because readers may infer their endorsement of the data and conclusions. Acknowledge the source of any financial support.

Tables
Type each table, double-spaced, on a separate page. Do not format tables as photographs. Number them consecutively in roman numerals and give each a short descriptive heading. Place explanatory matter in footnotes to the table, including any non-standard abbreviations. Omit internal horizontal and vertical rules (lines). If data from another published or unpublished source are used, obtain permission and acknowledge fully. Make sure that tables are self-explanatory and understandable without reference to the text of the article.

Figures
Submit each figure as a separate file and in TIFF or EPS format with a resolution of at least 300 dpi. Number figures consecutively using Arabic numerals. Prepare the figures in proportion to each other, so that lettering, numerals and symbols in different figures will be roughly the same size after reduction. Decide whether a figure is to cover one, one-and-a-half or two columns of the journal in print, and then plan accordingly. Submit photographs scaled as near to printed size as possible. If magnification is significant, indicate using a bar on the print rather than a magnification factor in the figure legend. If someone appears in a photograph, either s/he must not be identifiable or written permission for use of the photograph must accompany the manuscript. Give each figure a legend containing sufficient information to make the figure intelligible without the reader having to refer to the text. Key all the legends together. If a figure has been published previously, acknowledge the original source and submit written permission from the copyright holder to reproduce it. Authors will be required to pay for the extra cost of printing illustrations in colour (USD 750).

References
Present the reference list with entries numbered in the order in which they are first mentioned in the text, i.e. consecutively, and include all works cross-referred in the text and in the tables and legends. Give the names of the first SIX authors in the case of multi-author works. If there are seven or more authors, give the names of the first six followed by et al. Verify accuracy of the reference list before submitting the manuscript for publication and abbreviate titles of journals in accordance with the style used in Index Medicus.

Identify reference indicators in the text, tables and legends using Arabic numerals in parentheses. For example, in the text, give the name of the author followed by the appropriate number in parentheses, e.g. 'Hansen (1) has reported . . .', 'Hansen & Olsen (2) have reported . . .', or by simply giving the appropriate number in parentheses, e.g. 'As has recently been reported (1, 2) . . .'. When there are more than two authors, give only the name of the first author followed by 'et al.'. Information from manuscripts submitted but not yet accepted should be cited in the text as 'Unpublished observations' (in parentheses).

Abbreviations
Please consult the CBE Manual for standard abbreviations. Explain any non-standard abbreviations (to be avoided if possible) in the text the first time they are used. Avoid abbreviations in the title of the article. Express quantities and units in accordance with the recommendations of the Système International d'Unités (SI).

Letters to the Editor
Correspondence concerning articles in the journal, short reports, etc., will be considered for publication under the heading “Correspondence”. Do not exceed 500 words, and include no more than one table/illustration and 10 references (and no Abstract).
