- Only standard symbols and abbreviations could be used in the main text of the manuscript. All abbreviations, except units (l, m2, kg , etc.) may be used only after the original spelling of each term in decrypted form and then its abbreviation form, which is given in parentheses. If more than 10 acronyms are used in the article, a separate list of abbreviations should be established.

- When describing drugs one should indicate their International Nonproprietary Names (INN) and stick carefully calibrated doses.

- Semantic allocations are to be made bold or italic.

- Grants, sources of financial support, technical and other assistance are indicated in the “Acknowledgements” section at the end of the text before the list of references.

IIa. Illustrative material

- Illustrations (tables, charts, diagrams, drawings, photographs) are to be submitted as separate files in jpg, tiff, eps, psd; captions – in a separate file in Word format in the form of numbered. All illustrations numbers should be consistent with the numbering in the text of the manuscript. Image size in the sending file must be equal to its final physical size (in millimeters), with a resolution of at least 300 dpi or of not less than 2 megabytes. The name of each file containing the image must conform to the numbering of figures – “Fig. 1 (2, 3, etc.)”. Screen copies (printscreens) will not be accepted.

- Tables allow concisely and accurately represent important information, thereby reducing the volume of the main text of the manuscript. Tables should contain only the necessary data, and provide a generalized and statistically processed materials. Do not use horizontal or vertical lines within the table. Legends and explanatory captions should be placed below the table. Reductions used in a table must be decoded at the end of a legend in alphabetical order. References to tables in the text of the manuscript are made as follows: “Table 1 (2, 3, etc.)”. Do not insert tables into the text of the manuscript.

- Drawings (schemes of operations, etc.) must be carried out professionally in black on a white background, photographed and presented in a quality digital image. Letters, numbers, symbols in the figures should contrast with the background, to be clear, uniform and large enough to remain legible after the publication of the picture.

- The same type of images must be identical in size, scale, nature of information. Names and explanations of the content of the picture should be presented in the caption (legend), and not on the figure.

- Radiographs, tomograms, ultrasonograms and other diagnostic images, as well as images of operational and pathological preparations and microscopic slides are to be presented in the form of contrasting black and white, or (preferably) color photographs. Signatures below the micrographs shall indicate the scale (the magnification) and the method of staining.

- Other photos (intraoperative photos, images of devices, tools, equipment, etc.) should be sharp, possibly colored and contain easily understandable symbols. Photos of potentially identifiable people (patients, whose face is unmasked) must be accompanied by an indication of the written permission to be published.

- Captions (legends) must be typed on a separate sheet (in a text editor Word, font Times New Roman, size 12, line spacing 2.0, 2.5 cm in all margins, shifts in words and indentation – automatic) and numbered in Arabic numerals in order of appearance figures in the text. At the end of each legend authors must specify (in alphabetical order) and decipher all abbreviations in the figures available.

- If the drawing (table, photo etc.) has been previously published elsewhere, indicate the original source and obtain written permission from the copyright holder for reproduction the pattern, except for documents in the public domain.

IIb. Bibliographic references

- The Editorial Board invites the authors to make bibliographic references to original works. Avoid references to abstracts and review articles.

- The bibliographic references in the text of the manuscript, tables, and legends under tables and images are marked with Arabic numerals in square brackets, starting with [1] and then [2, 3, 4, 5 ....]. Do not use superscript numbers of references and endnotes. Number consecutively all bibliographic references as they appear in the text. In accordance with this numbering (in order of citation) compile a list of references where each bibliographic reference begins with the author’s name, or (if there is a large number of authors) – with a title of an article or book (see below – GOST 7.1–2003). References provided in tables or figure captions, but absent in the main text should be numbered in sequence corresponding to the first mention of the table or figure in the main text of the manuscript. Requirement to make a list of references in order of citation also applies to articles written by foreign authors in English.

- The list of references in manuscripts written in Russian, is to be drawn up in accordance with Russian standard GOST 7.1-2005 “Bibliographic record. Bibliographic description”**. References in manuscripts written by foreign authors in English, are to be compiled in accordance with European and American standards for bibliographic description of printed works. In the list of references would be done:

• – for books: surname and initials of the author, book title, place of publication (city), publisher, year, volume, number of pages, or a link to a specific page.
• – for journal articles: surname and initials of the author, article title, journal name, year, volume, issue, page numbers from and to, or link to a specific page.
• – for proceedings of scientific conferences: surname and initials of the author, title of article, title of the conference, place (city), year, page numbers to and from, or link to a specific page.
• – for dissertation abstracts: surname and initials of the author, title, place of publication (city), year, number of pages***.

- Do not include manuscripts (dissertations), unpublished works and textbooks in the list of references.

- When citing electronic materials authors are required to make reference to relevant Internet resources (electronic documents, databases, portals, sites, web pages, etc.).

- The Editorial Board of the journal “Clinical and Experimental Surgery. Journal named by Academician B.V. Petrovsky” adheres to the principles set forth in the Helsinki Declaration of the World Medical Association (WMA) “Ethical Principles for Medical Research Involving Human Subjects Research”, adopted by the 18th WMA General Assembly in June 1964, amended and supplemented by the General Assemblies of WMA in 1975– 2008 (http://www.wma.net/e/policy/b3.htm), and holds that all clinical researches involving human subjects should be conducted in accordance with such principles. In the “Material and methods” section, authors should specify that a written voluntary informed consent was obtained from all patients or volunteers before they were subjected to a scientific research.

- Information such as names, initials, numbers of patient records should not be published either in the text or illustrations (e.g. X-ray films) or captions to them, except in cases where such information is essential for scientific purposes. In such cases, a written voluntary consent of patients (parents or guardians) is mandatory. The same goes for images of patients. Authors should inform the patient, whether his or here data (including photographs) would be published in print or online. Informed consent requires that patients consenting to publish their data would be able to review the manuscript and illustrative material prior to publication.

- If animals are used as the study subjects, it should be noted in the text of the manuscript that authors have provided a humane attitude toward them. In the “Material and methods” section it is necessary to indicate that all investigators are acted in accordance with the “Rules for the Care and Use of Laboratory Animals” (see http://www.nap.edu/readingroom/ books/labrats/contents.html) or in accordance with local or national guidelines on that subject.

- The contribution of each author in the research must be essential. Each author should be directly involved in the research study and writing of the manuscript, and to be responsible for its content. Other participants in the work that do not meet criteria for authorship, should be specified in the “Acknowledgements” at the end of the manuscript.

Fee for publication will not be charged.
