General Submission of an original article implies: that the work described has not been published before (except in the form of an abstract or as part of a published lecture, review, or thesis); that it is not under consideration for publication elsewhere; that its publication has been approved by all coauthors, if any, as well as by the responsible authorities at the institute where the work has been carried out (including ethical committees and national licencing authorities); that, if and when the manuscript is accepted for publication, the authors agree to automatic transfer of the copyright to the publisher; and that the manuscript will not be published elsewhere in any language without the consent of the copyright holders.
Manuscripts should be submitted in triplicate (original and two copies); they should be double-spaced, with wide margins on one side of the paper only, and should be carefully prepared in the style of this journal and checked before submission. Typing errors should be corrected legibly. All manuscripts are subject to copy editing and, if necessary, will be returned to the authors for open questions to be answered or for missing information to be supplied before being sent to the printers. When extensive corrections are necessary, authors are responsible for having manuscripts retyped. Pages should be consecutively numbered, starting with the title page. The desired position of figures and tables should be marked in the margin. Changes in the proofs should be kept to a minimum: a charge will be made for changes introduced after the manuscript has been set in type.
Organization of the manuscript The speed of publication depends greatly upon following these guidelines precisely.
1. The manuscript should be divided clearly into an Introduction, Materials and Methods, Results, Discussion and Conclusion and References. The text should be concise and consistent as to spelling, abbreviations, etc…
2. The title page should include the title of the work, first and last name(s) of author(s), name of institution, any footnotes referring to the title (marked with an asterisk), and the address of the author to whom the proofs are to be sent. To facilitate communication between the authors, editors and publisher, the author should furnish a telex or fax number on the title page of the manuscript.
3.The abstract should be a summary of the hypothesis or aims of the work, the basic material and methods and the conclusion of the study.
4. Immediately following the abstract, up to 7 relevant key words should be sypplied for subject indexing.
5. Footnotes, other than those refering to the title heading, should be numbered consecutively.
6. The accuracy of the References is the responsibility of the authors. The list of references should only include works that are cited in the text and that have been published or accepted for publication. Personal communications should be mentioned in the text only. The list should be in alphabetical order according to the first author’s name. Works by two authors should be listed alphabetically according to the second author’s name, then chronologically; those by three or more authors should be in chronological order. References should be styled as follows. Biancos J.A., Eimaleh D.R., Leppo Jl.A. (1986) Effect of glucose and insulin infusion on the myocardial extraction of a radioiodinated methyl-substituted fatty acid. Eur. J. Nucl. Mad. 12: 120-124. Gullberg G.T., Malko J.A., Eisner R.L. (1983) Bounday determination methods for attenuation correction in single photon emission computed tomography. In: Esser PD (ed). Emission computed tomography: current trends. Society of Nuclear Medicine, New-York, pp. 33-53. Meltzer YL (1971) Hormonal and attractant pesticide technology. Noyes data, Park Ridge, New Jersey. Citations in the text should be given in parentheses (Child 1941; Godwin and Cohen 1969; MacWilliams et al., 1970), except when the author is mentioned, as in “and the study of Hiliman and Tasca (1977)”.
7. Tables should be submitted on separate sheets. Numerical data given in graphs and tables must not be duplicated.
8. All figures, whether photographs, graphs or diagrams, should be numbered consecutively throughout and submitted on separate sheets. Plate layouts or single figures may either match the width of the column (9 cm) or be 11.8 cm in width with the legend at the side. The maximum height for a figure or plate is 23 cm, including the legend printed at its foot. Photographs can be grouped into plates. They must be mounted on regular bond paper, not on cardboard. All photographs and electron micrographs should be supplied as highcontrast glossy prints trimmed at right angles. Inscriptions on illustrations should allow for reduction if this is necessary; figures and letters should have a final height of 2 mm after reproduction. Color illustrations will be accepted: however, the authors will be expected to make a contribution (approximately BF 7.500 per page) to the additional costs involved.
9. Typewritten mathematical equations should be clear, so that there is no opportunity for misinterpretation by the printer. All letters contained in formulae as well as single letters in the text are automatically set in italics and therefore require no underlining. Hence, abbreviations that appear in formulae and are to be set in roman type (the type normally used for the text) should be specially marked by underlining in yellow, if possible. It will be helpful to the printer if Greek characters are underlined in red and script in green. Lowercase letters should then be underlined once and capital letters twice; this applies also to Latin letters in formulae (in pencil). Boldface type (heavy type) should be marked by wavy underlining. Subscripts and superscripts should be indicated by an inverted caret below the line, or a caret above the line, respectively: 12 12; a subscript to a subscript is styled: 12. Obscure primes and dots must be clarified for the printer. The following must be differentiated clearly: number 1 and letter l; zero 0 and letters O, o, e, c, n, u, v, primes and apostrophes. Fractional exponents should be used in, stead of root signs and the solidus (/) for fractions whenever they are horizon. tal; an exp notation must be numbered sequentially in arabic numerals in parentheses on the right-hand side of the page.
10. Fifty (50) offprints of each paper with additional copies are available in lots of 100, (provided the order is teceived with the corrected proofs) may be supplied charged to the authors. 11. Enclose the picture of the first author of each article.
