Papers may come from any country but must be written in English. Manuscripts may be submitted for consideration as regular papers or reports. Authors are urged to keep the length of regular papers to six printed pages or fewer. Reports (formerly known as Accelerated publications) can be no longer than five printed pages, including all spaces, references, figures and tables. A five-page paper is usually less than 30,000 characters plus two figures or tables (if each figure or table is less than one-fourth page). Manuscripts submitted under multiple authorship are reviewed on the assumption that all listed authors concur in the submission. How to submit Manuscripts should be submitted either in-person to the editorial office, secretary of the Journal, Faculty of Science, Ain Shams University, Abbassia, Cairo, Egypt, or electronically via the journal’s e-mail address: EJPAS@sci.asu.edu.eg Initial manuscript submission 1. Prepare the text in Microsoft Word 6.0 or a later version. Organize the manuscript similar to a published paper. The document will have the approximate appearance and layout shown (below): The text should be single-spaced (Use 12-point Times New Roman font). Use 11-point Times New Roman font, and select size and bolding to mimic the appearance shown above for the title section. Do not imbed graphics in the Word document, but submit them independently (separate files) or insert them at the end of the PDF file that you will form (point “3.” below). 2. Prepare figures at publication-quality resolution, using only applications capable of generating high-resolution TIFF or EPS files. Number each figure. 3. Using Adobe Acrobat (see http://adobe.com/products/main.html for information), save your manuscript text and figures in a single file in PDF format with the figures at the end. The file name should be one word with no spaces and have a .pdf extension (e.g. manuscript.pdf). Authors are responsible for assuring the accuracy and quality of the PDF. 4. Print the PDF file and carefully review text and figures. It is the author's responsibility to make sure that the manuscript is suitable for review. Manuscripts that do not have figures of sufficient quality for scientific review will be returned to authors. Check the PDF file size. Most files should be around 1 MB but not larger than 10 MB. 5. Submit your manuscript, where you will need: Contact information for the submitting author Information about the authors and the manuscript A cover letter with information for the Editor and Associate Editors Single PDF file of your manuscript under 10 MB in size. Organization of the manuscript 1. Formatted for standard A4 paper 2. Single spacing throughout 3. Text typed in 12-point Times New Roman 4. Manuscript is to be arranged in the following order: (a) title, author(s), complete name(s) of institution(s) and running title (b) abstract (c) introduction (d) materials and methods (e) results (f) discussion (g) references (h) footnotes (i) figure legends (j) tables (k) figures 5. Number all pages, including those with figures. Text Title section It is important that the major findings of your study are intelligible to all JBC readers, including those who are not specialists in the field. The title should be as short and informative as possible (not to exceed two lines). If acronyms or abbreviations are used, the name/term should be first indicated in full followed by the short form/acronym (e.g. , Visualization of Polarized Membrane Type 1 Matrix Metalloproteinase (MT1-MMP) Activity in Live Cells by Fluorescence Resonance Energy Transfer (FRET) Imaging.) A full name is not required for the most common biochemical abbreviations (e.g. ATP). Please review your title and abstract carefully to make sure they convey your essential points succinctly and clearly. Authors Contains names of all authors and their complete mailing addresses and identifies who will receive correspondence regarding the a) name b) telephone and fax numbers c) e-mail address Running title Will be at the top of each printed page and cannot exceed 60 characters and spaces Abstract Should succinctly and clearly describe the major findings reported in the manuscript Must not exceed 350 words Introduction Presents the purpose of the studies reported and their relationship to earlier work in the field Should not be an extensive review of the literature nor, in general, exceed one typed page Materials and methods Brief but sufficiently complete to permit a qualified reader to repeat the experiments reported Only truly new procedures should be described in detail Cite previously published procedures in references Modifications of previously published procedures not given in detail except when necessary to repeat the work Results Presented in figures and tables Some results not requiring documentation given solely in the text Discussion Concise (usually less than two typed pages) Focused on the interpretation of the results rather than a repetition of the "Results" section N.B. The results and discussion sections can be merged into a single section References Cited in text by number and not by author and date Numbered consecutively in the order of appearance References for journals and books should be in the following styles: 1. Ellis, R. R., Yuan, J. and Horvitz, H. R. (1991). Mechanisms and functions of cell death. Annu. Rev. Cell Biol., 7:663–698. 2. Sambrook, J., Fritsch, E. F., and Maniatis, T. (1989). Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, NY 3. References appearing as e-pubs should be in the following style: Farrell, C., and Rollman, L. (June 10, 2004) J. Biol. Chem. 10.1074/jbc.M401234200 Journal names are abbreviated according to Chemical Abstracts (http://www.cas.org/). Authors are responsible for the accuracy of the references. Tables and figures The number of tables and figures used to present data essential to illustrate or prove a point should be kept to a minimum. Tables should have titles and sufficient experimental detail in a legend immediately following the title to be understandable without reference to the text. Each column in a table must have a heading, and abbreviations, when necessary, should be defined in the legend. Figures should have titles and legends containing sufficient detail to make the figure easily understood. Legends should be printed consecutively in a separate section of the manuscript. Authors are responsible for providing digital art that has been properly sized and cropped. Numbers, letters and symbols used in multipaneled figures must be consistent. Indicate the figure number on each figure. All figures should be created with applications that are capable of preparing high-resolution TIFF or EPS files acceptable for publication. Although you will initially submit figures with the text in a single PDF file, we will require submission of figures as separate TIFF or EPS files at publicationquality resolution for print and online publication if your paper is accepted. It is the author's responsibility to verify the quality of the graphics in the PDF that has been prepared and that compression of the files for submission does not distort the images. While image manipulation is often desirable for clarity and/or brevity of presentation, manipulation for deceptive purposes either to unfairly enhance or eliminate or otherwise obscure data is misconduct and will be resolved according to journal policy. Publication charges Setup fee: A L.E 100 setup fee is charged to each submitted manuscript that is due upon initial submission and should be handed to the editorial office (address above) prior to the review process. Page charges: There is a set fee for published manuscripts that is L.E 500 including the first 6 printed pages in addition to a L.E 75 per-page charge for each additional page over 6. Color figures: We encourage authors to use color figures when they will enhance the presentation of the data. The cost is L.E 250 for each page containing color. (Note: When using the electronic submission system, any figure submitted in color will be reviewed and processed with the understanding that the figure will be published in color) Reprints: 10 reprints are provided free of charge. To order any additional reprints, pricing is based upon the quantity ordered. All page and color fees must be paid by the authors.
